712 Fix dependence on computed configure variables.
713 * doc/Makefile.am (common_dep): Depend on $(top_srcdir)/configure not

715 as PACKAGE_VERSION, are seen.
716 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.

742 but, in general, we still can't be sure of our next release name.
743 * bootstrap: Add a quick hack to remove from .gitignore the
744 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
745 entry. This should really be fixed in gnulib instead.
746 * bootstrap.conf (gnulib_modules): Add gnumakefile.
747 * configure.ac (AC_INIT): Set version name by invoking

778 Fix some .gitignore and .cvsignore problems.
779 * bootstrap (insert_sorted_if_absent): Replace all uses with...

781 .gitignore entries before passing them to insert_sorted_if_absent.
782 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that

801 * lib/.gitignore, lib/.cvsignore (/unsetenv.c): Add.
802 * m4/.gitignore, m4/.cvsignore (/environ.m4): Add.
804 * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
805 the first argument because it may become position-dependent, and unset
806 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
807 Add comments explaining these issues in more detail.

871 Revert prior patch, by working around autoconf regression.
872 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
873 ("Output file name: ("): Uncomment test.
874 ("Output file name: )"): Likewise.
875 Based on an idea from Noah Misch.
877 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
879 Work-around an Autoconf 2.62 AT_SETUP bug that was not present in

893 Update to the current gnulib CVS repository, and fix trigraph handling
895 * bootstrap: Update gnulib CVS repository URL.
896 (symlink_to_dir): Encapsulate the code that guarantees the destination
897 directory exists into...
898 (check_dst_dir): ... this new function, and...
899 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
900 fail when copying files into lib/uniwidth/.
901 * src/output.c (prepare_symbols): When writing yytname muscles, where
902 symbol names will be encoded in C-string literals, tell quotearg to
903 escape trigraphs. This used to be the default in gnulib.
904 * tests/regression.at (Token definitions): Because of the change in
905 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
906 escapes trigraphs in symbol names. Thus, yytname no longer has
907 trigraphs unnecessarily doubly escaped. Update test case output.
908 Extend test case to be sure Bison's own error messages will no longer
909 have trigraphs in symbol names unnecessarily escaped once.

924 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
925 consistency. Update the -g and -x entries now that they take
926 arguments. Use brackets to indicate optional arguments.
927 * src/getargs.c (usage): Explain the relationship between arguments of
928 long and short options more completely. Document --defines and -d
929 separately since the former takes an argument but, for POSIX Yacc, the
931 (short_options): Let -W take an optional argument like --warnings.

989 (yypstate_allocated): Define for impure push parsers regardless of
990 whether the pull interface is also requested.
991 * tests/push.at (Push Parsing: Multiple impure instances): Extend to
992 check impure push parsers without the pull interface.
994 * data/yacc.c (yypstate_new): Don't try to invoke yyerror since
995 yyerror takes arguments specified by %parse-param while yypstate_new

1526 Make xml2dot.xsl and --graph produce the same output.
1527 * data/xslt/xml2dot.xsl (xsl:template match="rule"): Use a ` '
1528 instead of a `\n'. That is, don't add escapes yet or they'll be doubly

1583 * data/location.cc (b4_namespace): Likewise.
1584 * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
1585 inside a new table in the general %define entry. Document `%define

1587 explains it more completely in the case of C++.
1588 (C++ Bison Interface): Mention `%define namespace' instead of
1590 (Table of Symbols): Remove the `%define push_pull' entry. The %define
1592 * tests/c++.at (Relative namespace references): New test case.
1593 (Absolute namespace references): New test case.
1594 (Syntactically invalid namespace references): New test case.

1631 * data/bison.m4 (b4_cat): New.
1632 (b4_error, b4_error_at): Use b4_cat to send error directives directly

1637 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately

1640 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
1641 instead of just in them. Recognize @\n in both places. Both expand to

1686 parsing requests here...
1687 * data/yacc.c: ... hack this to switch to push.c any time

1689 will go away when we mv push.c yacc.c.
1690 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
1691 push parsing is not supported since unused %define variables are

1922 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
1925 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
1927 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
1928 true since it's then always used regardless of whether yyoverflow is
1929 defined. Reported by Christian Burger at
1930 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
1931 * THANKS: Add Christian Burger.
1933 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
1934 node names: say "Decl Summary" not "Bison Declaration Summary".
1936 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
1938 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
1939 determine whether this function has already complained about an invalid
1940 value for a %define boolean variable, don't check whether Bison has
1941 ever examined the value. As written, the check was a tautology.
1942 Instead, record and check for this complaint using a separate muscle.
1944 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
1946 Fix push parsing memory leak reported by Brandon Lucia at
1947 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
1948 * THANKS: Add Brandon Lucia.
1949 * data/push.c (yypstate_delete): Free the stack if it was reallocated
1950 but the parse never completed and thus freed it.
1951 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
1952 * tests/testsuite.at: Include push.at.
1953 * test/push.at: New.
1954 (Push Parsing: Memory Leak for Early Deletion): New test case.
1956 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
1958 Improve handling of multiple S/R conflicts in the same state and of S/R
1959 conflicts involving multiple reductions.
1960 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
1961 set for a state here or Bison will abort if it is reassigned on a
1962 later conflicted reduction in the same state.
1963 Similarly, don't finalize and assign the solved conflicts report here
1964 or it will be lost if it is reassigned on a later conflicted reduction
1966 (set_conflicts): Instead, assign them both here after all S/R conflicts
1967 in the state have been fully examined.
1968 * src/print.c (shift_set): Rename to...
1969 (no_reduce_set): ... this.
1970 (print_reductions): Update for rename, and add %nonassoc error action
1971 tokens to no_reduce_set so that, when printing the first remaining
1972 reduction on an error action token, the reduction is enclosed in
1974 (print_results): Update for rename.
1975 * tests/conflicts.at (Solved conflicts report for multiple reductions
1976 in a state): New test case.
1977 (%nonassoc error actions for multiple reductions in a state): New test
1980 * src/main.c (main): Don't depend on C99 features.
1982 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
1984 * build-aux/.cvsignore: Add compile.
1985 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
1988 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
1990 * bootstrap (slurp): Create target directories that don't exist.
1991 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
1993 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
1995 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
1997 * closure.c (closure): Likewise.
1998 * state.h (reductions): Comment sorting of rules.
1999 (state): Comment sorting of items.
2001 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
2003 Fix C++ test cases after recent Gnulib changes. Discussed starting at
2004 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
2005 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
2006 definition in order to avoid Gnulib headers since we don't use config.h
2008 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
2009 rather than AT_DATA so that config.h is included.
2011 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
2013 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
2014 instead of fprintf. Guard these functions with #if YYDEBUG instead of
2015 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
2016 and so that YYFPRINTF is guaranteed to be defined here.
2018 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
2020 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
2022 (muscle_percent_define_check_values): ... this more helpful function.
2023 Again, it's not used yet, but it will be.
2024 * src/muscle_tab.h: Likewise.
2026 Improve some comments in parser table construction.
2027 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
2028 (generate_states): Don't mention ruleset, which is internal to closure.
2029 * src/closure.c (closure): Explain sorting of core and itemset, which
2030 is required for this function to behave correctly.
2031 * src/closure.h (closure): Mention sorting.
2033 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
2035 * src/lalr.c (state_lookahead_tokens_count): For code readability,
2036 move the check for disabled transitions to an aver since conflict
2037 resolution hasn't happened yet.
2039 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
2040 labels a state as inconsistent just because it has error transitions.
2041 The original form of this check appeared in revision 1.1 of lalr.c,
2042 which was committed on 1991-12-21. Now (at least), changing the
2043 consistency label on such a state appears to have no useful effect in
2044 any of the places it is examined, which I enumerate below. The key
2045 point to understanding each item in this enumeration is that a state
2046 with an error transition is labelled consistent in the first place only
2047 if it has no rules, so the check cannot matter for states that have
2048 rules. (1) Labelling a state as inconsistent will cause set_conflicts
2049 to try to identify its conflicts, and a state must have *rules* to have
2050 conflicts. (2) Labelling a state as inconsistent will affect how
2051 action_row sets the default *rule* for the state. (3) Labelling a
2052 state as inconsistent will cause build_relations to add lookback edges
2053 to *rules* in that state.
2054 * src/state.h (struct state): Word the comment for member consistent
2057 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
2059 Don't depend on C99 features.
2060 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
2061 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
2062 * src/reader.c (check_and_convert_grammar): Fix for-loop.
2063 * src/state.c (state_mark_reachable_states): Fix for-loop.
2064 (state_remove_unreachable_states): Fix for-loop.
2066 Don't widen struct state with member reachable just to temporarily
2067 record reachability. Instead, use a local bitset.
2068 * src/state.h (struct state): Remove member.
2069 * src/state.c (state_new): Don't initialize it.
2070 (state_mark_reachable_states): Rename to...
2071 (state_record_reachable_states): ... this, and use bitset.
2072 (state_remove_unreachable_states): Use bitset.
2074 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
2076 * src/Makefile.am (yacc): Quote target action commands properly so
2077 that the yacc script isn't corrupt. Reported by Hans Aberg at
2078 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
2080 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
2081 the case of pure parsers. Reported by Frans Englich at
2082 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
2083 * THANKS: Add Frans Englich.
2085 * NEWS (2.3a+): In the %code entry, reference section `Bison
2086 Declaration Summary' from the manual now since the %code summary has
2088 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
2089 in the rules section must be terminated by semicolons.
2091 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
2093 Extend the front-end API for %define variables to more completely
2094 mirror the back-end. This will be useful in the future.
2095 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
2096 Update comments to mention the new front-end counterparts of these
2098 * src/muscle_tab.c (MUSCLE_COMMON_DECODE): New macro with common code

2106 implementation more closely.
2107 (muscle_percent_define_invalid_value): New function.
2108 * src/muscle_tab.h (muscle_percent_define_get,
2109 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
2112 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
2114 * NEWS (2.3a+): Mention yesterday's state-removal change.
2115 (2.3a): Remove the %language entry, which was added after 2.3a.
2116 * src/LR0.c, src/closure.c, src/closure.h, src/conflicts.c,
2117 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
2118 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
2119 tests/existing.at: Update copyright date.
2121 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
2123 If conflict resolution makes states unreachable, remove those states,
2124 report rules that are then unused, and don't report conflicts in those
2126 * src/conflicts.c, src/conflicts.h (conflicts_update_state_numbers):
2127 New global function.
2128 * src/lalr.c, src/lalr.h (lalr_update_state_numbers): New global

2141 an unused rule is discovered.
2143 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
2145 Minor code cleanup in parser table construction.
2146 * src/LR0.c (new_itemsets): Use item_number_is_symbol_number.
2147 (new_itemsets, save_reductions): Update for rename to nitemset.
2148 * src/closure.c (nritemset): Rename to...
2149 (nitemset): ... this since the "r" appears to meaningless and isn't
2150 used in the comments.
2151 (closure): Update for rename.
2152 * src/closure.h (nritemset): Update extern to...
2153 (nitemset): ... this.

2159 2007-04-04 Paul Eggert <eggert@cs.ucla.edu>
2161 * THANKS: Use ASCII for Sebastien Fricker's name. Bison source
2162 still sticks to ASCII. Sorry!

2197 abstract". Rename "%define union_name" to "%define stype".
2198 Rename method names according to previous patch.
2199 (Java Scanner Interface): Describe "%code lexer" instead of
2200 "%pure-parser" and "%define single_class".
2201 (Java Differences): Mention "%code lexer".
2203 * tests/java.at (_AT_DATA_JAVA_CALC_Y): Remove final argument.
2204 Include scanner here, using macros from tests/local.at.
2205 (AT_DATA_CALC_Y): Remove final argument.
2206 (_AT_CHECK_JAVA_CALC): Likewise.
2207 (AT_CHECK_JAVA_CALC): Likewise. Test all four combinations

2211 (AT_BISON_OPTION_POPDEFS): Pop it.
2213 2007-03-07 Juan Manuel Guerrero <juan.guerrero@gmx.de>
2215 DJGPP spefic issue. Inhibit the use of disallowed characters for
2216 file name genertion on Win98, WinXP, etc. These are |<>":?*\
2217 and concern testsuite case 46.
2218 * Makefile.am: djgpp/testsuite.sed added to EXTRA_DIST
2219 * djgpp/testsuite.sed: Inhibit the use of disallowed characters.
2220 * djgpp/config.bat: Inhibit the use of disallowed characters.

2226 values are interpreted.
2227 * doc/bison.texinfo (Decl Summary): Clean up and extend %define
2228 documentation a little more.
2229 * src/muscle_tab.c (MUSCLE_USER_NAME_CONVERT,
2230 muscle_percent_define_insert, muscle_percent_code_grow): New

2240 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
2241 Bison uses of names rather than just skeleton uses of names.
2242 (b4_percent_define_get, b4_percent_define_ifdef): Rename

2249 * src/muscle_tab.c, src/muscle_tab.h (muscle_percent_define_flag_if,
2250 muscle_percent_define_default): New functions mimicking
2251 b4_percent_define_flag_if and b4_percent_define_default.
2253 For %define variables, report locations for invalid values and
2255 * data/bison.m4 (b4_percent_define_flag_if): Read
2256 b4_percent_define_loc(VARIABLE) to report the location of an invalid
2258 (b4_percent_define_default): Save a special location in
2259 b4_percent_define_loc(VARIABLE) in case the default value for VARIABLE

2263 (muscle_percent_define_insert): Record the location of VARIABLE in
2264 muscle percent_define_loc(VARIABLE), and use it to report the previous

2271 * src/muscle_tab.h (muscle_location_grow): Prototype.
2272 * tests/input.at (%define errors): Update expected output.
2273 * tests/skeletons.at (%define boolean variables: invalid skeleton
2274 defaults): New test case.
2276 2007-02-28 Joel E. Denny <jdenny@ces.clemson.edu>
2278 * src/print.c (lookahead_set, state_default_rule): Remove.
2279 (print_reductions): Replace state_default_rule invocation with
2280 equivalent use of yydefact, which was computed in token_actions in
2282 (print_results): Don't allocate lookahead_set.
2284 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
2286 * data/lalr1.java: Prefix all private members with yy.
2288 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
2290 Use YYFPRINTF instead of fprintf where appropriate. Reported by
2291 Sebastien Fricker at
2292 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
2293 * THANKS: Add Sebastien Fricker.
2294 * data/glr.c, data/push.c, data/yacc.c (yy_reduce_print): Implement.
2295 * doc/bison.texinfo (Tracing): Make it clearer that YYFPRINTF must

2300 * bootstrap: Remove occurrences of .#bootmp from lib/Makefile.
2302 2007-02-13 Juan Manuel Guerrero <juan.guerrero@gmx.de>
2304 * djgpp/config.bat: Adjustments concerning the use of autoconf 2.61.

2308 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
2310 Undo my 2007-02-07 change, switching back to the c-strcase module
2311 introduced in the 2007-02-03 change. Bruno Haible reported that
2312 the 2007-02-07 change would be dangerous in Turkish if we add a
2313 language whose name contains "i", since "i" is not lowercase "I"
2315 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
2316 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
2317 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
2318 * m4/.cvsignore: Remove strcase.m4.
2319 * src/getargs.c: Revert 2007-02-07 change, as follows.
2320 Include c-strcase.h.
2321 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
2323 2007-02-11 Bruno Haible <bruno@clisp.org>
2325 Enable the Java related testsuite tests when the only Java compiler
2326 found is a gcj < 4.3. Discussed at
2327 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
2328 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
2330 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
2332 * data/Makefile.am: Update copyright date.
2333 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
2334 yypstate_new returns NULL.
2335 (yypstate_new): Return NULL if malloc does.
2336 * src/reader.c (packgram): Move translation of rule actions from the
2337 beginning of packgram to...
2338 (check_and_convert_grammar): ... here right before packgram is invoked
2339 so it's easier to write more complete comments, and remove redundant
2342 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
2344 As in semantic actions, make @$ in %initial-action, %destructor, and
2345 %printer imply %locations.
2346 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
2348 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
2349 (@$ in %initial-action implies %locations,
2350 @$ in %destructor implies %locations,
2351 @$ in %printer implies %locations): ... these new test cases.
2353 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
2355 Undo most of the 2007-02-03 change, switching to the strcase module
2356 now that gnulib strcase has been fixed.
2357 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
2358 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
2359 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
2360 * m4/.cvsignore: Add strcase.m4.
2361 * src/getargs.c: Revert 2007-02-03 change, as follows.
2362 Don't include c-strcase.h.
2363 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
2364 strcasecmp has "unspecified behavior" outside the POSIX locale,
2365 but it works fine in practice if at least one argument is ASCII,
2366 as is the case in Bison.
2368 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
2370 * tests/java.at: Skip tests if only one of javac/java is present.
2371 Reported by Joel E. Denny.
2372 * tests/atlocal.in: Adjust copyright years.
2374 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
2376 * data/lalr1.java (Stack): Work around old verifiers that disallow
2377 access to the private fields of an inner class, from the outer class.
2378 We can make Stack's fields public because user code doesn't have access
2379 to the instance of Stack used by parse(). Reported by Paul Eggert.
2381 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
2383 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
2384 the right spot for these files?
2385 * bootstrap.conf (gnulib_modules): Add c-strcase.
2386 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
2388 * src/getargs.c: Include c-strcase.h.
2389 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
2390 to avoid unspecified behavior.
2392 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
2394 * doc/bison.texinfo (Decl Summary): Correct typo.
2396 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
2398 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
2399 Complain if the value does not match empty, "true" or "false".
2400 * data/c++.m4: Adjust default definitions of %define variables.
2401 * data/java.m4: Adjust default definitions of %define variables.
2402 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
2404 * tests/input.at (Boolean %define variables): Test new behavior.
2406 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
2408 * NEWS: Mention java.
2409 * TODO: Remove things that are done.
2410 * bootstrap.conf: Add javacomp-script and javaexec-script.
2411 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
2413 * data/Makefile.am: Add new files.
2414 * data/java-skel.m4: New.
2415 * data/java.m4: New.
2416 * data/lalr1.java: New.
2418 * doc/bison.texinfo: Put "A Complete C++ Example" under
2419 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
2420 under Other Languages.
2422 * src/getargs.c (valid_languages): Add Java.
2423 * src/getargs.h (struct bison_language): Update size of string fields.
2425 * tests/Makefile.am: Add java.at.
2426 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
2427 * tests/java.at: New.
2428 * tests/testsuite.at: Include it.
2430 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
2433 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
2434 at_directive_argv arguments so these no longer have to be global
2435 variables. Also, update the implementation for the following changes.
2436 (fail_for_at_directive_too_many_args,
2437 fail_for_at_directive_too_few_args): Add at_directive_name argument.
2438 (at_directive_name): Remove as at_directive_argv[0] will be used for
2440 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
2441 for the directive name.
2442 (at_directive_argc, at_directive_argv): Make these local within
2443 skel_lex instead of global.
2444 (INITIAL): Update directive start action for above changes.
2445 (SC_AT_DIRECTIVE_ARG): Rename to...
2446 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
2447 (SC_AT_DIRECTIVE_SKIP_WS): Update.
2448 (scan_skel): Move yylex_destroy to...
2449 (skel_scanner_free): ... here.
2450 * tests/skeletons.at (installed skeleton file name): Rename to...
2451 (installed skeleton file names): ... this.
2453 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
2455 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
2456 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
2457 Summary" not "Directives".
2458 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
2459 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
2460 since the former is now the more complete one.
2461 (Prologue Alternatives): Likewise and do the same for %defines.
2462 (Table of Symbols): Add summary of %code, add summary of %define, and
2463 move full %code documentation to...
2464 (Decl Summary): ... here for consistency with other entries in these
2466 Move %define entry in order to keep this list alphabetized.
2467 Reword %define entry a little to put less emphasis on the skeleton
2468 concept, which most users shouldn't have to think about.
2470 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
2472 Adjust to recent gnulib changes.
2473 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
2474 Add string.h, string_.h, unistd_.h, wchar_.h.
2475 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
2476 * src/system.h: Don't include <stpcpy.h>; this is now done by
2479 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
2481 Simplify implementation of unqualified %code, implement macros for
2482 uniform treatment of boolean %define flags. Document %define.
2483 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
2484 b4_percent_code_ifdef): New.
2485 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
2486 * data/c++.m4: Define default value for global_tokens_and_yystype.
2487 * data/glr.cc: Likewise.
2488 * data/location.cc: Use b4_percent_define_flag_if.
2490 * doc/bison.texinfo (Decl Summary): Document %define.
2492 * src/parse-gram.y (Unqualified %code): Change muscle name to
2494 (content.opt): Default to empty.
2496 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
2498 Implement support for relative and absolute skeleton file names.
2499 Discussed starting at
2500 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
2501 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
2502 (Bison Options): Document in --skeleton entry.
2503 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
2504 full_skeleton can't necessarily hold all of pkgdatadir.
2505 If the specified skeleton file name contains a `/', don't prepend
2507 * src/parse-gram.y (prologue_declaration): If the specified skeleton
2508 file name contains a `/', prepend the grammar file directory.
2509 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
2510 * skeletons.at: New file.
2511 (relative skeleton file names): New test case.
2512 (installed skeleton file names): New test case.
2513 * tests/testsuite.at: Include skeletons.at.
2515 * bootstrap: Update copyright to 2007.
2517 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
2519 * bootstrap: Remove occurrences of .#bootmp from the files.
2521 2007-01-17 Akim Demaille <akim@epita.fr>
2523 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
2525 Use per-type %printer.
2527 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>

2541 (Calc++ Scanner): Exit with failure if we can't open the input
2543 Accept "-" standing for stdin.
2544 (Calc++ Top Level): Print the result only if the parsing was

2551 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
2552 and Joel E. Denny <jdenny@ces.clemson.edu>
2554 Clean up %define and %code implementation in M4 some. Most
2555 importantly, rename all related macros to be in the b4_percent_define
2556 and b4_percent_code namespaces. Also, complete support for `.' in
2557 %define variable names and %code qualifiers.
2558 * data/bison.m4 (b4_check_user_names): Check for special
2559 "SKELETON-NAMESPACE(name)" macros instead of using two nested
2561 (b4_get_percent_define, b4_get_percent_code): Rename to...
2562 (b4_percent_define_get, b4_percent_code_get): ... these.
2563 Extend documentation with examples.
2564 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
2565 b4_percent_define_skeleton_variables and
2566 b4_percent_code_skeleton_qualifiers.
2567 Expect any value for the %define variable `foo' to be stored in the
2568 macro named `b4_percent_define(foo)'; expect any %code blocks for the
2569 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
2570 expect any unqualified %code blocks to be stored in a macro named
2571 `b4_percent_code_unqualified'.
2572 Use m4_indir so that %define variable names and %code qualifiers can
2573 contain `.', which is allowed by the grammar parser.
2574 (b4_percent_define_default): New macro to set a default value for a
2576 (m4_wrap): Update wrapped code, and fix some underquoting.
2577 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
2578 Expect grammar uses of %define variables and %code qualifiers to be
2579 defined in b4_percent_define_user_variables and
2580 b4_percent_code_user_qualifiers.
2581 * data/c++.m4: Use b4_percent_define_default rather than
2582 m4_define_default. Fix some underquoting. Skeleton usage of %define
2583 variable define_location_comparison now implies skeleton usage of
2584 %define variable filename_type.
2585 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
2586 data/push.c, data/yacc.c: Update macro names.
2587 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
2590 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
2592 DJGPP specific issues.
2594 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
2595 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
2597 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
2599 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
2600 run parsers in all tests so that Valgrind is invoked during
2601 maintainer-check-valgrind.
2602 (Duplicate representation of merged trees): Free all semantic values.
2603 (Duplicated user destructor for lookahead): Likewise.
2605 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
2607 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
2608 command-line prefix.
2609 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
2610 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
2611 miss Valgrind messages.
2612 (Exploding the Stack Size with Malloc): Likewise.
2614 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
2616 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
2617 locals. Reported by Juan Manuel Guerrero at
2618 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
2619 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
2620 Fix some indentation also.
2621 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
2622 explaining this issue.
2624 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
2625 and Joel E. Denny <jdenny@ces.clemson.edu>
2627 Simplify union and prologue handling, and escape union and lex/parse
2628 params with digraphs.
2629 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
2630 values to the empty string since these are no longer guaranteed
2631 initialized by the front-end.
2632 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
2633 braces around b4_user_stype since this is no longer done by the
2635 * src/files.c, src/files.h (pre_prologue_obstack,
2636 post_prologue_obstack): Remove.
2637 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
2638 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
2639 with digraphs. This fixes lex params and parse params.
2640 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
2641 * src/output.c (prepare): Remove muscle insertion of the prologues.
2642 (output): Remove freeing of pre_prologue_obstack and
2643 post_prologue_obstack.
2644 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
2645 than prologue_augment for prologue parsing so you don't need prologue
2647 (grammar_declaration): For %union RHS, use `braceless' instead of
2648 "{...}" so that braces are already stripped and code is escaped with
2650 * src/reader.c (prologue_augment): Remove.
2651 (reader): Remove initialization of pre_prologue_obstack and
2652 post_prologue_obstack.
2653 * src/reader.h (prologue_augment): Remove.
2655 * data/c.m4: Remove stray parenthesis.
2657 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2659 Remove quotes from variables names in %define directives and from
2660 qualifiers in %code directives, and restrict the characters that are
2661 allowed in them to M4-friendly ones. For %define, continue to support
2662 the quoted form as a deprecated feature. Discussed starting at
2663 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
2664 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
2666 * doc/bison.texinfo (Prologue Alternatives): Update.
2667 (Decl Summary): In %defines entry, update mention of `%code requires'
2668 and `%code provides'.
2669 (C++ Location Values): Update %define uses.
2670 (Calc++ Parser Interface): Likewise.
2671 (Calc++ Parser): Likewise, and update `%code requires' uses.
2672 (Table of Symbols): Update %code documentation.
2673 * src/parse-gram.y (prologue_declaration): For %define variables, use
2674 `variable' instead of `STRING'.
2675 (grammar_declaration): For %code qualifiers, use `ID' instead of
2677 (variable): New nonterminal that takes an `ID' or a `STRING'.
2678 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
2680 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
2681 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
2682 (%define errors): Update %define uses.
2684 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2686 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
2687 instead of muscle_insert for %define values so that M4-special
2688 characters are replaced with digraphs.
2689 * tests/input.at (%define errors): Extend to check weird values.
2691 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2693 Instead of having skeletons declare all valid %define variables and
2694 %code qualifiers, provide macros that retrieve the associated values
2695 and build these lists automatically. Thus Bison will now warn when a
2696 variable or qualifier is not used by the skeleton in the current
2697 invocation regardless of whether it might sometimes be used by that
2698 skeleton in other invocations. Also, move all %define value macros to
2699 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
2700 form, which is replaced by %code.
2701 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
2702 (b4_check_user_names): ... this, and change the series of valid name
2703 arguments to a single list argument for names used in the skeleton
2704 similar to the existing list argument for names used in the grammar.
2705 Warn instead of complaining.
2706 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
2707 values and %code code, to format %code code properly, and to build
2708 lists of all %define variables and %code qualifiers used in the
2709 skeleton: b4_skeleton_percent_define_variables and
2710 b4_skeleton_percent_code_qualifiers.
2711 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
2713 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
2714 the skeleton names lists can finish building first. In place of
2715 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
2716 expect the lists b4_user_percent_define_variables and
2717 b4_user_percent_code_qualifiers.
2718 * data/c++.m4: Where setting default values for b4_parser_class_name,
2719 b4_location_type, b4_filename_type, b4_namespace, and
2720 b4_define_location_comparison, update their names to the
2721 b4_percent_define_ namespace.
2722 * data/glr.c: Don't use b4_check_percent_define_variables and
2723 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
2724 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
2725 (b4_parser_class_name, b4_namespace): Define these using
2726 b4_get_percent_define for parser_class_name and namespace.
2727 * data/location.cc: Use b4_get_percent_define.
2728 * data/push.c: Don't use b4_check_percent_define_variables and
2729 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
2730 * data/yacc.c: Likewise, and don't call m4_exit in
2731 b4_use_push_for_pull_if or m4_wrap code will never execute.
2732 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
2734 (muscle_grow_user_name_list): ... this for consistency with the
2735 terminology used in bison.m4.
2736 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
2737 %define variable names, and rename muscle used_percent_define_variables
2738 to user_percent_define_variables.
2739 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
2740 user_percent_code_qualifiers.
2742 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
2743 {CODE} form is no longer accepted.
2744 * tests/input.at (Reject bad %code qualifiers): Rename to...
2745 (Reject unused %code qualifiers): ... this, and update test output.
2746 (%define error): Update test output.
2748 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
2750 Check for unrecognized %define variables similar to checking for
2751 unrecognized %code qualifiers. Check for redefined %define variables.
2752 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
2754 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
2755 (b4_check_percent_define_variables): New, also wraps it.
2756 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
2757 variables using b4_check_percent_define_variables.
2758 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
2759 all those exercised in the test suite and all those listed in the
2760 `Default values' section of c++.m4. Are there others?
2761 * data/push.c, data/yacc.c: Declare no valid %define variables.
2762 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
2763 similar to muscle_find, but it works even when the muscle stores a
2765 (muscle_grow_used_name_list): New function for constructing the used
2766 name list muscles that b4_check_for_unrecognized_names requires.
2767 * src/parse-gram.y (prologue_declaration): Warn if a variable is
2768 %define'd more than once. Define the b4_used_percent_define_variables
2769 muscle with muscle_grow_used_name_list.
2770 (grammar_declaration): Abbreviate %code code with
2771 muscle_grow_used_name_list.
2772 * tests/input.at (%define errors): New.
2774 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
2776 Provide warn_at, complain_at, and fatal_at function callbacks to the
2777 skeletons, and use this for %code qualifier complaints.
2778 * data/bison.m4 (b4_error_at): New, invoked by...
2779 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
2780 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
2781 @fatal_at(...@) directives.
2782 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
2783 qualifiers in b4_used_percent_code_qualifiers and to use
2785 * src/location.c, src/location.h (boundary_set_from_string): New global
2787 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
2789 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
2790 to b4_used_percent_code_qualifiers.
2791 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
2793 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
2794 (lineno): Rename to...
2795 (out_lineno): ... this so I don't misunderstand it again.
2796 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
2797 here; these newlines are in the input but not the output file.
2798 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
2799 (at_directive_perform): ... this new static function, and add handling
2800 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
2802 * tests/input.at (Reject bad %code qualifiers): Update test output with
2803 locations and extend.
2805 * tests/output.at (Output file name: [, Output file name: ]): Remove
2806 bogus comment about these tests failing.
2808 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
2810 Clean up b4_check_percent_code_qualifiers a little.
2811 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
2812 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
2813 documentation and add examples.
2814 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
2817 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
2819 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
2820 unreliable -- especially when they're hidden inside another macro.
2821 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
2822 data/c.m4: Remove m4_divert(-1).
2823 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
2824 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
2825 m4_divert_push(0) and m4_divert_pop(0).
2826 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
2827 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
2828 pushed and popped by m4sugar, should be first on the stack.
2830 Provide warn, complain, and fatal function callbacks to the skeletons.
2831 This provides more flexibility than m4_fatal, improves the error
2832 message format, and captures messages for translation. Discussed
2834 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
2835 * data/bison.m4 (b4_error): New, invoked by...
2836 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
2837 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
2838 directives. Because these M4 macros might be called when the current
2839 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
2840 the previous removal of uses of m4_divert, which caused trouble.
2841 (b4_check_percent_code_qualifiers): Use b4_complain instead of
2842 m4_fatal to report unrecognized %code qualifiers.
2843 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
2844 push parser requests.
2845 * data/glr.c: Use b4_complain instead of m4_fatal to report
2846 non-deterministic push parser requests.
2847 Update @output usage to @output(...@) form.
2848 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
2849 report missing %defines. Update @output usage to @output(...@) form.
2850 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
2852 * src/main.c (main): Invoke skel_scanner_free.
2853 * src/scan-skel.h (skel_scanner_free): Prototype new function.
2854 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
2855 obstack_for_string from flex-scanner.h.
2856 (YY_DECL): Use to declare skel_lex static.
2857 (decode_at_digraphs): Remove; now handled in the new
2858 SC_AT_DIRECTIVE_ARG start condition.
2859 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
2861 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
2862 at_directive_argv): New static globals.
2863 (INITIAL): Use fail_for_invalid_at.
2864 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
2865 recognize the start of a generalized `@directive(...@)' form and
2867 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
2868 directive args (using the new obstack_for_string), to decode the
2869 contained @ diagraphs, and to perform the directive. It recognizes
2870 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
2872 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
2873 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
2875 (scan_skel): Initialize obstack_for_string on the first call.
2876 (skel_scanner_free): New function to free obstack_for_string.
2877 * tests/input.at (Reject bad %code qualifiers): Update test output.
2879 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
2881 Consolidate the 4 prologue alternative directives (%code, %requires,
2882 %provides, and %code-top) into a single %code directive with an
2883 optional qualifier field. Discussed at
2884 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
2885 * NEWS (2.3a+): Rewrite the existing entry for the prologue
2887 * doc/bison.texinfo (Prologue Alternatives): Update.
2888 (Decl Summary): Update to %code "requires" and %code "provides".
2889 (Calc++ Parser): Update to %code "requires".
2890 (Table of Symbols): Remove entries for %requires, %provides, and
2891 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
2892 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
2893 are replaced by b4_percent_code_provides and b4_percent_code_requires,
2894 which are skeleton-specific.
2895 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
2896 declare what %code qualifiers it supports and to complain if any other
2897 qualifiers were used in the grammar.
2898 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
2899 and b4_user_code([b4_percent_code_provides]) in place of
2900 b4_user_requires and b4_user_provides.
2901 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
2902 Add b4_user_code([b4_percent_code_top]) and
2903 b4_user_code([b4_percent_code]).
2904 Invoke b4_check_percent_code_qualifiers.
2905 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
2906 PERCENT_REQUIRES): Remove.
2907 (grammar_declaration): Remove RHS's for %code-top, %provides, and
2908 %requires. Rewrite the %code RHS as the unqualified form defining the
2909 muscle b4_percent_code. Add another RHS for the qualified %code form,
2910 which defines muscles of the form b4_percent_code_QUALIFIER and the
2911 b4_used_percent_code_qualifiers muscle.
2912 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
2913 PERCENT_REQUIRES): Remove.
2914 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
2915 %code "requires" and %code "provides".
2916 * tests/input.at (Reject bad %code qualifiers): New.
2918 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
2920 Use the new code_props interface for destructors and printers.
2921 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
2922 printer_location members, and change the type of the destructor and
2923 printer members to code_props.
2924 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
2925 symbol_printer_get, semantic_type_destructor_set,
2926 semantic_type_printer_set, default_tagged_destructor_set,
2927 default_tagless_destructor_set, default_tagged_printer_set,
2928 default_tagless_printer_set): Use code_props in arguments and return
2929 types in place of char const * and location.
2930 (symbol_destructor_location_get, symbol_printer_location_get): Remove
2931 since the locations are now contained in the return of
2932 symbol_destructor_get and symbol_printer_get.
2933 * src/output.c (symbol_destructors_output, symbol_printers_output):
2935 (symbol_code_props_output): ... this to eliminate duplicate code.
2936 (output_skeleton): Update to use symbol_code_props_output.
2937 * src/reader.c (symbol_should_be_used): Update use of
2938 symbol_destructor_get.
2939 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
2940 Update uses of the various _destructor_set and _printer_set functions.
2941 * src/symtab.c: (default_tagged_destructor_location,
2942 default_tagless_destructor_location, default_tagged_printer_location,
2943 default_tagless_printer_location): Remove since we...
2944 (default_tagged_destructor, default_tagless_destructor,
2945 default_tagged_printer, default_tagless_printer): ... change the type
2946 of these to code_props.
2947 (symbol_new, semantic_type_new, symbol_destructor_set,
2948 semantic_type_destructor_set, symbol_destructor_get,
2949 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
2950 symbol_check_alias_consistency, default_tagged_destructor_set,
2951 default_tagless_destructor_set, default_tagged_printer_set,
2952 default_tagless_printer_set): Update.
2953 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
2954 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
2956 (symbol_print): Use SYMBOL_CODE_PRINT.
2958 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
2960 Use the new code_props interface for rule actions.
2961 * src/symlist.h (symbol_list): Replace action, action_location, and
2962 used members with a code_props action_props member.
2963 * src/reader.c (symbol_should_be_used, grammar_rule_check,
2964 grammar_midrule_action, grammar_current_rule_merge_set,
2965 grammar_current_rule_symbol_append, packgram): Update.
2966 * src/scan-code.h (translate_rule_action): Remove, no longer used.
2967 * src/scan-code.l (handle_action_dollar): Update.
2968 (translate_rule_action): Remove, no longer used.
2969 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
2971 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
2973 Use the new code_props interface in parse-gram.y.
2974 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
2975 Update all uses of translate_* functions to use the new code_props
2976 interface and to use gram_scanner_last_string_free and
2977 code_scanner_last_string_free where possible.
2978 (grammar_declaration): symbol_list_destructor_set and
2979 symbol_list_printer_set now perform the translation, so don't do it
2980 here. Use gram_scanner_last_string_free where possible.
2981 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
2982 translate_code): Remove, no longer used.
2983 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
2984 symbol_list_printer_set): Perform code translation here rather than
2985 depending on the caller to do so.
2987 * src/symlist.h (struct symbol_list): Correct some documentation typos.
2988 * src/scan-gram.h (gram_last_string): Remove declaration.
2989 * src/scan-gram.l (last_string): Declare it static.
2991 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
2993 Encapsulate code properties and related functionality for the various
2994 destructors, printers, and actions into a code_props structure and
2995 interface. This patch merely implements code_props in scan-code.h and
2996 scan-code.l. Future patches will rewrite other modules to use it.
2997 Discussed starting at
2998 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
2999 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
3000 consistently initialize const structs that have an empty location
3002 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
3003 to ensure consistency.
3004 * src/scan-code.h (code_props): New structure.
3005 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
3006 function, macro, and const global variable for initializing a
3007 code_props with no code.
3008 (code_props_plain_init, code_props_symbol_action_init,
3009 code_props_rule_action_init, code_props_translate_code): The rest of
3010 the new code_props functional interface. Among other things, the init
3011 functions set the code_props kind field so that
3012 code_props_translate_code will know whether to behave like
3013 translate_symbol_action, translate_rule_action, or translate_code.
3014 These old translate functions must remain until all other modules are
3015 updated to use the new code_props interface.
3016 (code_scanner_last_string_free): New function similar to
3017 gram_scanner_last_string_free.
3018 (code_scanner_free): Add documentation.
3019 * src/scan-code.l: Implement the new interface.
3020 (code_lex): Make it static, add a code_props* argument, and remove the
3022 (last_string): New static global similar to the one in scan-gram.l.
3023 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
3025 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
3026 code_props since Bison may one day use this information for destructors
3028 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
3029 (handle_action_dollar): Use symbol_list_n_get and set used flag
3030 directly since symbol_list_n_used_set is removed.
3031 (translate_action): Add a code_props* argument and remove the rule,
3032 action, and location arguments. Pass the code_props* on to code_lex.
3033 (translate_rule_action, translate_symbol_action, translate_code):
3034 Rewrite as wrappers around the new code_props interface.
3035 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
3036 it would eventually need to break the encapsulation of code_props.
3038 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
3040 * etc/.cvsignore: New.
3042 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
3044 Add maintainer-push-check to run maintainer-check using push parsing in
3045 place of pull parsing where available.
3046 * Makefile.am (maintainer-push-check): New.
3047 * data/bison.m4 (b4_use_push_for_pull_if): New.
3048 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
3049 appropriately based on their existing values.
3050 (yypush_parse): Don't print push-parser-specific diagnostics if push
3051 parsing is being used in place of pull parsing.
3052 * data/yacc.c: If push parsing should replace pull parsing, redirect to
3054 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
3055 variable, and insert b4_use_push_for_pull_flag into muscles.
3056 * tests/Makefile.am (maintainer-push-check): New.
3058 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
3060 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
3061 (whether successful or failed) so that yypush_parse can be invoked
3062 again to start a new parse using the same yypstate.
3063 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
3064 check multiple yypull_parse invocations on the same yypstate. For pull
3065 mode, extend to check multiple yyparse invocations.
3066 (Exploding the Stack Size with Alloca): Extend to try with
3068 (Exploding the Stack Size with Malloc): Likewise.
3070 * tests/calc.at (Simple LALR Calculator): Don't specify
3071 %skeleton "push.c" since %push-pull-parser implies that now.
3072 * tests/headers.at (export YYLTYPE): Don't check for the push
3073 declarations. Otherwise, this test case can't be used to see if push
3074 mode can truly emulate pull mode.
3075 * tests/input.at (Torturing the Scanner): Likewise.
3076 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
3077 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
3078 AT_YACC_IF, which now includes the case of push mode since %skeleton
3079 need not be used for push mode. This will be more intuitive once
3080 push.c is renamed to yacc.c.
3082 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
3084 For push mode, convert yyparse from a macro to a function, invoke yylex
3085 instead of passing a yylexp argument to yypull_parse, and don't
3086 generate yypull_parse or yyparse unless %push-pull-parser is declared.
3087 Discussed starting at
3088 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
3089 * data/bison.m4 (b4_pull_if): New.
3090 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
3091 * data/push.c: Improve M4 quoting a little.
3092 (b4_generate_macro_args, b4_parenthesize): Remove.
3093 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
3094 any time a pull parser is requested.
3095 Don't #define this as a wrapper around yypull_parse. Instead, when
3096 both push and pull are requested, make it a function that does that
3098 (yypull_parse): If there's a b4_prefix, #define this to
3099 b4_prefix[pull_parse] when both push and pull are requested.
3100 Don't define this as a function unless both push and pull are
3102 Remove the yylexp argument and hard-code yylex invocation instead.
3103 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
3105 * src/getargs.c (pull_parser): New global initialized to true.
3106 * getargs.h (pull_parser): extern it.
3107 * src/output.c (prepare): Insert pull_flag muscle.
3108 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
3109 (prologue_declaration): Set both push_parser and pull_parser = true for
3110 %push-pull-parser. Set push_parser = true and pull_parser = false for
3112 * src/scan-gram.l: Don't accept %push_parser as an alternative to
3113 %push-parser since there's no backward-compatibility concern here.
3114 Scan %push-pull-parser.
3115 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
3116 instead of %push-parser.
3117 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
3118 prototype it in the module that calls yyparse.
3119 * tests/input.at (Torturing the Scanner): Likewise.
3120 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
3122 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
3124 Update etc/bench.pl. Optimize push mode a little (the yyn change
3125 deserves most of the credit).
3126 * Makefile.am (SUBDIRS): Add etc subdirectory.
3127 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
3128 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
3129 yytoken, yyval, and yyloc declarations to...
3130 (yyparse or yypush_parse): ... here to improve performance. For
3131 yypush_parse invocations after the first, be sure to assign yyn its old
3133 (yypstate_new): Don't bother initializing the yyresult field since the
3134 initial value isn't used.
3135 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
3136 remove the #define that, in push mode, set it to yyps->NAME.
3137 * etc/Makefile.am: New.
3138 * etc/bench.pl: Remove and build it instead from...
3139 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
3140 "tests/bison" from the build directory by default rather than just
3141 invoking "bison" from $PATH.
3142 (calc_grammar): Update push parser code: don't declare yylval globally,
3143 don't define yyparse_wrapper, and don't #define yyparse.
3144 (bench_grammar): Update to check all working combinations of yacc.c,
3145 push.c, impure, pure, pull, and push.
3147 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
3149 For push mode, add pull wrappers around yypush_parse.
3150 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
3151 (yypull_parse): New function wrapping yypush_parse.
3152 (yyparse): New #define wrapping yypull_parse.
3153 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
3155 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
3156 prototype yylex in the module that calls yyparse, and don't prototype
3157 yyparse there. Otherwise, the yyparse expansion won't compile.
3158 * tests/input.at (Torturing the Scanner): Likewise.
3160 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
3162 Enable push parsers to operate in impure mode. Thus, %push-parser no
3163 longer implies %pure-parser. The point of this change is to move
3164 towards being able to test the push parser code by running the entire
3165 test suite as if %push-parser had been declared.
3166 * data/push.c (yypush_parse): For impure mode, remove the
3167 yypushed_char, yypushed_val, and yypushed_loc arguments.
3168 Instead, declare these as local variables initialized to the global
3169 yychar, yylval, and yylloc.
3170 For the first yypush_parse invocation only, restore the initial values
3171 of these global variables when it's time to read a token since they
3172 have been overwritten.
3173 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
3175 * tests/calc.at (Simple LALR(1) Calculator): Always declare
3176 %pure-parser along with %push-parser since this test case was designed
3177 for pure push parsers.
3178 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
3179 (AT_YACC_OR_PUSH_IF): New.
3180 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
3181 add a note that it's still wrong for some cases (as it has been for a
3183 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
3184 %push-parser no longer implies %pure-parser.
3186 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3188 Remove some unnecessary differences between the pull parser code and
3189 the push parser code. This patch enables yynerrs in push mode.
3190 * data/push.c: Reformat M4 a little.
3191 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
3192 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
3193 because push mode is on. Instead, if pure mode is on, move yynerrs
3195 (b4_declare_parser_state_variables): ... here.
3196 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
3197 to yyps->NAME so it can be used in yypush_parse.
3198 (yypush_parse): Don't omit uses of yynerrs in push mode.
3200 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3202 Fix bug such that the first pushed token's value and location are
3203 sometimes overwritten (sometimes by %initial-action) before being used.
3204 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
3205 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
3206 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
3207 more closely mimic the pull parser logic.
3208 Don't copy the pushed token to yychar, yylval, and yylloc until it's
3209 time to read a token, which is after any initialization of yylval and
3211 (gottoken): Rename label to...
3212 (yyread_pushed_token): ... for clarity and to avoid infringing on the
3215 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3217 Rearrange initialization of the parser state variables so that the
3218 skeleton doesn't have to have a copy for pull mode and another for push
3219 mode. This patch also fixes at least a bug such that yylloc was not
3220 initialized (with b4_location_initial_line and
3221 b4_location_initial_column) upon calling yypush_parse. However, that
3222 initialization now overwrites the first token's location;
3223 %initial-action assigning @$ already did the same thing, and both bugs
3224 will be fixed in a later patch.
3225 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
3226 (b4_declare_parser_state_variables): Remove initialization of yytoken,
3227 yyss, yyvs, yyls, and yystacksize.
3228 (yypstate_new): Remove initialization of some yypstate fields: yystate,
3229 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
3231 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
3232 yyps->NAME so it can be used in yypush_parse.
3233 (yyparse or yypush_parse): For yypush_parse, don't print the
3234 "Starting parse" diagnostic for invocations after the first.
3235 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
3236 yypush_parse, only do it for the first invocation.
3237 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
3238 initialization to occur in yypush_parse but only on the first
3241 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3243 * data/push.c: Add CPP guards around push parser declarations in both
3244 the header and the code file.
3245 In the code file, move the push parser declarations to the same place
3246 they appear in the header file.
3247 Clean up the M4 some, especially the inconsistent underquoting in
3248 some b4_c_function_def and b4_c_function_decl uses.
3250 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3252 Encapsulate the push parser state variables into an M4 macro so the
3253 push skeleton doesn't have to list them again for pull mode's yyparse.
3254 For push mode, remove yypush_parse's local equivalents of these
3255 variables to eliminate unnecessary copying between the two sets at
3256 run-time. This patch also fixes at least a bug related to multiple
3257 %initial-action invocations in push mode.
3258 * data/push.c (b4_declare_parser_variables): Rename to...
3259 (b4_declare_scanner_communication_variables): ... this for clarity and
3261 (b4_declare_yyparse_variables): Remove and move its contents to the one
3262 spot where it was invoked.
3263 (b4_declare_parser_state_variables): New macro containing the parser
3264 state variables required by push mode.
3265 (struct yypstate): Replace all fields but yynew with
3266 b4_declare_parser_state_variables.
3267 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
3268 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
3269 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
3270 (yyparse or yypush_parse): For yyparse in pull mode, replace local
3271 parser state variable declarations with
3272 b4_declare_parser_state_variables.
3273 Don't initialize parser state variables when calling yypush_parse since
3274 yypstate_new already does that.
3275 Invoke the user's initial action only upon the first yypush_parse
3277 Remove all code that copies between the local parser state variables
3280 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3282 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
3283 prevent a name collision in a future patch where these names will
3284 sometimes be #define'd.
3285 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
3286 since it no longer has the same name as the existing argument.
3287 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
3289 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
3290 and Joel E. Denny <jdenny@ces.clemson.edu>
3292 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
3293 that the argument is case-insensitive, and there's no `=' here.
3294 For the %skeleton entry, mention that %language is better.
3295 (Bison Options): Likewise for --language and --skeleton. Move the
3296 --skeleton entry so that the `Tuning the parser' section is sorted
3297 alphabetically on long options.
3298 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
3299 %language directive in detail here; cross-reference the %language
3300 documentation instead.
3301 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
3302 `%require "2.3b"' so that the example is always up-to-date.
3303 (Table of Symbols): Add entries for %language and %skeleton.
3304 * examples/extexi (normalize): Instead of replacing every %require
3305 argument with the current Bison version, just substitute for
3306 `@value{VERSION}'. This guarantees that we're testing what actually
3307 appears in the documentation.
3308 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
3309 rather than `@VERSION@'.
3311 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3313 * NEWS: Reword the %language news a bit, and put it earlier.
3315 * src/getargs.c (skeleton_arg): Last arg is now location const *.
3316 Rewrite to simplify the logic.
3317 (language_argmatch): Likewise.
3318 (program_name): We now own this var.
3319 * src/getargs.h (struct bison_language): Use char[] rather than
3322 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
3324 * src/complain.c (program_name): Remove decl; no longer needed.
3325 * src/main.c (program_name): Remove; now belongs to getargs.
3327 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
3329 * NEWS: Document %language.
3331 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
3333 * data/c-skel.m4, data/c++-skel.m4: New files.
3334 * data/glr.c: Complain on push parsers.
3336 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
3338 (Decl Summary): Document %language and %skeleton.
3339 (Command line): Document -L.
3341 * examples/extexi: Rewrite %require directive.
3342 * examples/calc++/Makefile.am: Pass VERSION to extexi.
3344 * src/files.c (compute_exts_from_gc): Look in language structure
3346 (compute_file_name_parts): Check whether .tab should be added.
3347 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
3348 (language, skeleton_arg, language_argmatch): New.
3349 (long_options): Add --language.
3350 (getargs): Use skeleton_arg, add -L/--language.
3351 * src/getargs.h: Include location.h.
3352 (struct bison_language, language, skeleton_arg, language_argmatch): New.
3353 * src/output.c (prepare): Pick default skeleton from struct language.
3354 Don't dispatch C skeletons here.
3355 * src/parse-gram.y (PERCENT_LANGUAGE): New.
3356 (prologue_declaration): Add "%language" rule, use skeleton_arg.
3357 * src/scan-gram.l ("%language"): New rule.
3359 * tests/calc.at: Test %skeleton and %language.
3360 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
3361 (AT_GLR_IF): Look for %skeleton "glr.cc".
3362 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
3363 (AT_YACC_IF): Reject %language.
3365 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3367 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
3368 since it wasn't used; only the typedef name 'semantic_type' is needed.
3369 Also, omit trailing white space.
3371 * bootstrap: Sync from coreutils.
3372 (gnulib_extra_files): Add build-aux/announce.gen.
3373 (slurp): Adjust .gitignore files like .cvsignore files.
3374 * build-aux/announce-gen: Remove from CVS, since bootstrap
3377 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
3379 Make %push-parser imply %pure-parser. This fixes several bugs; see
3380 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
3381 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
3383 * data/push.c: Don't bother testing b4_push_if when deciding whether
3384 to expand b4_declare_parser_variables globally.
3385 (yypush_parse): Likewise in here.
3387 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
3388 (yy_reduce_print): Reformat M4 for readability.
3390 2006-12-15 Bob Rossi <bob@brasko.net>
3391 and Joel Denny <jdenny@ces.clemson.edu>
3393 * data/push.c (yypstate): Add typedef, and update all uses of
3394 struct yypstate to just yypstate.
3395 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
3397 2006-12-14 Bob Rossi <bob@brasko.net>
3399 * data/push.c (yypush_parse): Declare prototype regardless of
3402 2006-12-14 Bob Rossi <bob@brasko.net>
3404 * data/push.c (yyparse): Remove the prototype and the #define when in
3407 2006-12-13 Bob Rossi <bob@brasko.net>
3409 * data/push.c (yypstate_init): Rename to...
3410 (yypstate_new): ... this and use b4_c_function_def.
3411 (yypstate_delete): New.
3412 (yypush_parse): Change parameters yynval and yynlloc to be const.
3413 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
3414 yypstate_delete functions.
3416 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
3418 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
3419 strange test case titles. Reported by Bob Rossi.
3421 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
3423 * TODO: Add pointer to Sylvain Schmitz's work on static detection
3424 of potential ambiguities in GLR grammers.
3426 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
3428 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
3429 `bison ', use m4_index instead of m4_substr since chopping up a string
3430 containing M4-special characters causes problems here.
3432 Fix a couple of bugs related to special characters in user-specified
3433 file names, and make it easier for skeletons to compute output file
3434 names with the same file name prefix as Bison-computed output file
3436 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
3437 b4_parser_file_name and b4_spec_defines_file instead of
3438 @output_parser_name@ and @output_header_name@, which are now redundant.
3439 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
3440 b4_parser_file_name, b4_spec_defines_file, and the new
3441 @basename(FILENAME@) instead of @output_parser_name@ and
3442 @output_header_name@, which inappropriately escaped the file names as
3444 * src/files.c (all_but_ext): Remove static qualifier.
3445 (compute_output_file_names): Move `free (all_but_ext)' to...
3446 (output_file_names_free): ... here since all_but_ext is needed later.
3447 * src/files.h (all_but_ext): Extern.
3448 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
3449 exactly what MUSCLE_INSERT_STRING used to do.
3450 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
3451 characters are escaped properly.
3452 * src/output.c (prepare): Define muscle file_name_all_but_ext as
3454 For pkgdatadir muscle, maintain previous functionality by using
3455 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
3456 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
3457 digraphs would never be expanded. Hopefully no one has M4-special
3458 characters in his Bison installation path.
3459 * src/scan-skel.l: Don't parse @output_header_name@ and
3460 @output_parser_name@ anymore since they're now redundant.
3461 In @output, use decode_at_digraphs.
3462 Parse a new @basename command that invokes last_component.
3463 (decode_at_digraphs): New.
3464 (BASE_QPUTS): Remove unused.
3465 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
3466 (Output file name): New tests.
3468 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
3470 Warn about output files that are generated by the skeletons and that
3471 conflict with other output files.
3472 * data/glr.c: Don't generate the header file here when glr.cc does.
3473 * src/files.c (file_names, file_names_count): New static globals.
3474 (compute_output_file_names): Invoke output_file_name_check for files
3475 not generated by the skeletons and remove existing checks.
3476 (output_file_name_check): New function that warns about conflicting
3478 (output_file_names_free): Free file_names.
3479 * src/files.h (output_file_name_check): Declare.
3480 * src/scan-skel.l: Invoke output_file_name_check for files generated by
3482 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
3483 (Conflicting output files): New tests.
3485 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3487 * doc/bison.texinfo: Fix a couple of typos.
3489 2006-12-08 Bob Rossi <bob@brasko.net>
3491 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
3493 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
3495 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
3496 (yypush_parse): Rename yypvars argument to yyps and remove redundant
3498 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
3499 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
3501 2006-12-07 Bob Rossi <bob@brasko.net>
3502 and Joel Denny <jdenny@ces.clemson.edu>
3504 * data/push.c (yypvarsinit): Change return type from void* to struct
3505 yypvars*. No longer cast to void* on return.
3506 (struct yypvars): Remove yylen since it need not be remembered between
3507 yypushparse invocations.
3508 (yypushparse): Don't copy between yylen and pv->yylen.
3510 2006-12-05 Bob Rossi <bob@brasko.net>
3512 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
3513 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
3514 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
3515 (struct yypvars): Remove b4_declare_parser_variables.
3516 (yypvarsinit): Remove init code for removed variables.
3517 (global scope): Do not declare b4_declare_parser_variables if
3519 (yypushparse): Add b4_declare_parser_variables.
3520 Init new local variables, and remove init code for removed
3523 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
3524 and yyparse for other modes.
3525 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
3526 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
3527 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
3528 (AT_PURE_LEX_IF): True if pure or push parser.

3606 grammar is maintained with Bison's highest standards.

3611 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
3612 later. Reported by Paul Eggert in
3613 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
3614 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
3615 * src/scan-code.l (translate_action): Don't bother invoking
3616 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
3617 (code_scanner_free): Instead of invoking
3618 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,
3620 * src/scan-gram.l (gram_scanner_free): Likewise.

3626 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
3627 has been called previously for the same key.
3628 (muscle_find): Return storage instead of value so that
3629 --enable-gcc-warnings doesn't produce warnings that the return discards
3630 const. aver that the value and storage are the same since storage
3631 could potentially be NULL when value is not.

3637 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
3638 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives

3659 src_extension, and header_extension.
3660 (output_file_names_free): New public function to free
3661 spec_verbose_file, spec_graph_file, spec_defines_file,
3662 parser_file_name, and dir_prefix.

3665 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
3666 (which previously existed but was unused), and quotearg_free.
3667 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
3668 * src/muscle_tab.c: Likewise.
3669 (muscle_entry): Make the value char const *,
3670 and add a new storage member that is char * and can be freed.
3671 (muscle_entry_free): New private function.
3672 (muscle_init): Use it instead of free.
3673 (muscle_insert, muscle_grow): Update and use new storage member.
3674 (muscle_code_grow): Free the string passed to muscle_grow
3675 since it's not needed anymore.
3676 * src/parse-gram.y (%union): Make `chars' member a `char const *', and

3691 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
3692 expecting a non-zero exit status sets --leak-check=summary and
3693 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
3694 this case, and we don't want to hear about it.
3696 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3698 * bootstrap (runtime-po/Makevars): Derive from po/Makevars

3715 declarations): Run tests with and without --warnings=midrule-values.
3717 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather

3739 empty subargument list. For example: `bison --warnings= parser.y'.
3741 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
3743 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
3744 the parser header file so that gcc doesn't warn.
3746 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>

3797 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
3798 like $@n instead of just @n so that the default %destructor/%printer
3799 logic doesn't see them as user-defined symbols.
3800 (symbol_is_dummy): Check for both forms of the name.
3801 * src/reader.c (packgram): Remove the `$' from each midrule symbol
3802 name for which the midrule value is referenced in any action.

3814 all actions have already been scanned in order to set `used' flags.
3815 Otherwise, checking that a midrule's $$ is set will not always work
3816 properly because the midrule check must forward-reference the midrule's

3945 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell

3951 * bootstrap (usage, main program, symlink_to_gnulib): Add option
3952 --copy. Inspired by a suggestion from Bruno Haible.
3954 2006-10-03 Jim Meyering <jim@meyering.net>

3959 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
3961 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than

4114 * src/getargs.c (usage): Rework to use conventions similar to
4115 coreutils, to make translation a bit easier and the code a bit
4116 smaller. Problem reported by Tim Van Holder.
4118 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
4120 Use some of gnulib's new modules, taken from coreutils.
4122 * bootstrap: Sync from coreutils, except add support for gnulib_files.
4123 * bootstrap.conf: New file.
4124 (gnulib_modules): Add configmake, inttypes, unistd.
4125 (XGETTEXT_OPTIONS): Add complain, complain_at,
4126 fatal, fatal_at, warn, warn_at, unexpected_end.
4127 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
4128 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
4130 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
4132 (GNULIB_AUTOCONF_SNIPPET): Remove.
4133 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
4135 * lib/.cvsignore: Add inttypes_.h.
4136 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
4137 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
4138 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
4139 no-longer-necessary initializations.
4140 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
4141 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
4142 use the unistd module.
4143 * src/system.h: Likewise.
4144 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
4145 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
4146 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
4147 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
4148 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
4149 * src/system.h: Include inttypes.h unconditionally, now that we
4150 use the inttypes module. Don't bother to include stdint.h, since
4151 inttypes.h now does that for us.
4152 (LOCALEDIR): Remove, now that we use the configmake module.
4153 * src/getargs.c: Include configmake.h.
4154 * src/main.c: Likewise.
4155 * src/output.c: Likewise.
4156 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
4157 not from $abs_top_builddir, since config.h moved.
4160 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
4161 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
4163 * src/parse-gram.y (symbol_declaration): Don't put statements
4164 before declarations; it's not portable to C89.
4165 * src/scan-code.l (handle_action_at): Likewise.
4167 * src/scan-code.l: Always initialize braces_level; the old code
4168 left it uninitialized and therefore had undefined behavior.
4170 Don't attempt to redefine 'assert', since it runs afoul of
4171 systems where standard headers (mistakenly) include <assert.h>.
4172 Instead, define and use our own alternative, called 'aver'.
4173 * src/reader.c: Don't include assert.h, since we no longer
4175 * src/scan-code.l: Likewise.
4176 * src/system.h (assert): Remove, replacing with....
4177 (aver): New function, taking a bool arg. All uses changed.
4178 * src/tables.c (pack_vector): Ensure that aver arg is bool,
4179 not merely an integer.
4181 2006-09-15 Bob Rossi <bob@brasko.net>
4183 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
4184 * data/c.m4 (YYPUSH): New.
4185 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
4186 * src/getargs.c (push_parser): New var.
4187 * src/getargs.h (push_parser): New declaration.
4188 * src/output.c (prepare): Add macro insertion of `push_flag'.
4189 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
4190 (prologue_declaration): Parse %push-parser.
4191 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
4192 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
4193 list of removed lines from the traces observed.
4194 (AT_CHECK_CALC_LALR): Added push parser tests.
4196 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
4198 * NEWS: Version 2.3a.
4199 * configure.ac (AC_INIT): Likewise.
4201 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
4202 "#define YYSTYPE int" that caused "make maintainer-check" to fail
4203 due to header ordering dependencies. I don't know why the #define
4206 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
4207 runtime cost when YYDEBUG is not defined, and so that some tests
4208 that used to fail now work. Problem and initial suggestion by
4210 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
4211 * data/glr.cc (b4_parser_class_name):
4212 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
4213 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
4214 (yydebug_) [YYDEBUG]: New member.
4215 (yycdebug_): Now defined only if YYDEBUG.
4216 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
4217 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
4218 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
4220 (debug_stream, set_debug_stream, debug_level, set_debug_level):
4221 Define only if YYDEBUG.
4222 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
4224 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
4225 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
4226 AT_CHECK_CALC_GLR_CC that are working now.
4228 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
4230 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
4231 We don't need them in glr.cc, and glr.c defines them.
4232 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
4233 assumes that defining it to anything is the same as defining
4234 it to 1. Problem reported by Paolo Bonzini.
4236 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
4238 * data/c.m4 (b4_null, b4_case): Define.
4239 * src/output.c (prepare_symbols): Use b4_null.
4240 (user_actions_output): Use b4_case.
4242 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
4244 * data/glr.c (b4_shared_declarations): Put start-header first,
4245 before any #includes that we generate, so that feature-test
4246 macros work. Problem reported by Michael Deutschmann in
4247 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
4248 * data/lalr1.cc: Likewise.
4249 * doc/bison.texinfo (Prologue): Document that feature-test macros
4250 should be defined before any Bison declarations.
4251 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
4252 that depend on location.hh after, not before, Bison decls, since
4253 we now include location.hh after the first user prologue.
4255 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
4256 Sander Brandenburg in
4257 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
4258 Also, fix minor white space and comment issues.
4259 (Prologue): Mention that it's better to define feature-test macros
4260 before Bison declarations. Problem reported by Michael Deutschmann.
4262 * README-cvs: Fix typo: "&" should be "&&". Problem reported
4264 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
4265 This adjusts to recent gnulib changes.
4267 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
4269 Finish implementation of per-type %destructor/%printer. Discussed
4271 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
4273 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
4274 * NEWS (2.3+): Add a description of this feature to the default
4275 %destructor/%printer description.
4276 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
4277 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
4278 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
4279 list node contains a semantic type.
4280 * src/symtab.c, src/symtab.h: Extend with a table that associates
4281 semantic types with their %destructor's and %printer's.
4282 (semantic_type_from_uniqstr, semantic_type_get,
4283 semantic_type_destructor_set, semantic_type_printer_set): New functions
4284 composing the public interface of that table.
4285 (symbol_destructor_get, symbol_destructor_location_get,
4286 symbol_printer_get, symbol_printer_location_get): If there's no
4287 per-symbol %destructor/%printer, look up the per-type before trying
4289 * tests/actions.at (Per-type %printer and %destructor): New test case.
4290 * tests/input.at (Default %printer and %destructor redeclared):
4291 Extend to check that multiple occurrences of %symbol-default in a
4292 single %destructor/%printer declaration is an error.
4293 (Per-type %printer and %destructor redeclared, Unused values with
4294 per-type %destructor): New test cases.
4296 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
4298 Require default %destructor/%printer to be declared using
4299 %symbol-default instead of an empty symbol list, and start working on
4300 new per-type %destructor/%printer. Discussed at
4301 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
4302 * NEWS (2.3+): Add %symbol-default to example.
4303 * bison.texinfo (Freeing Discarded Symbols): Likewise.
4304 (Table of Symbols): Add entry for %symbol-default.
4305 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
4306 (generic_symlist, generic_symlist_item): New nonterminals for creating
4307 a list in which each item is a symbol, semantic type, or
4309 (grammar_declaration): Use generic_symlist in %destructor and %printer
4310 declarations instead of symbols.1 or an empty list.
4311 (symbol_declaration, precedence_declaration, symbols.1): Update actions
4312 for changes to symbol_list.
4313 * src/reader.c: Update for changes to symbol_list.
4314 * src/scan-code.l: Likewise.
4315 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
4316 * src/symlist.c, src/symlist.h: Extend such that a list node may
4317 represent a semantic type or a %symbol-default in addition to just an
4318 ordinary symbol. Add switched functions for setting %destructor's and
4320 * tests/actions.at, tests/input.at: Add %symbol-default to all default
4321 %destructor/%printer declarations.
4323 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
4325 Whether the default %destructor/%printer applies to a particular symbol
4326 isn't a question of whether the user *declares* that symbol (in %token,
4327 for example). It's a question of whether the user by any means
4328 *defines* the symbol at all (by simply using a char token, for
4329 example). $end is defined by Bison whereas any other token with token
4330 number 0 is defined by the user. The error token is always defined by
4331 Bison regardless of whether the user declares it with %token, but we
4332 may one day let the user define error as a nonterminal instead.
4333 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
4334 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
4335 the meaning of "user-defined".
4336 * tests/actions.at (Default %printer and %destructor for user-declared
4337 end token): Rename to...
4338 (Default %printer and %destructor for user-defined end token): ...
4341 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
4342 computation of whether to apply the default, don't maintain a list of
4343 every Bison-defined symbol. Instead, just check for a first character
4344 of '$', which a user symbol cannot have, and check for the error token.
4346 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
4348 Don't apply the default %destructor or %printer to the error token,
4349 $undefined, or $accept. This change fits the general rule that the
4350 default %destructor and %printer are only for user-declared symbols,
4351 and it solves several difficulties that are described in the new test
4353 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
4354 * tests/actions.at (Default %printer and %destructor are not for error
4355 or $undefined, Default %printer and %destructor are not for $accept):
4358 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
4360 Allow %start after the first rule.
4361 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
4362 when parsing the first rule.
4363 (check_and_convert_grammar): Search for it here after all grammar
4364 declarations have been parsed. Skip midrules, which have dummy LHS
4366 * src/symtab.c (symbol_is_dummy): New function.
4367 * src/symtab.h (symbol_is_dummy): Declare it.
4368 * tests/input.at (%start after first rule): New test.
4370 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
4372 Redo some of the previous commit: add back the ability to use
4373 non-aliased/undeclared string literals since it might be useful to
4374 those declaring %token-table.
4375 * src/reader.c (check_and_convert_grammar): Undo changes in previous
4376 commit: don't worry about complaints from symbols_pack.
4377 * src/symtab.c (symbol_new, symbol_class_set,
4378 symbol_check_alias_consistency): Undo changes in previous commit: count
4379 each string literal as a new symbol and token, assign it a symbol
4380 number, and don't complain about non-aliased string literals.
4381 (symbols_pack): Since symbol_make_alias still does not decrement symbol
4382 and token counts but does still set aliased tokens to the same number,
4383 symbol_pack_processor now leaves empty slots in the symbols array.
4385 * tests/regression.at (Undeclared string literal): Remove test case
4386 added in previous commit since non-aliased string literals are allowed
4388 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
4389 remove unnecessary string literal declarations.
4390 * tests/sets.at (Firsts): Likewise.
4392 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
4394 Don't allow an undeclared string literal, but allow a string literal to
4395 be used before its declaration.
4396 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
4397 symbols_pack complained.
4398 * src/symtab.c (symbol_new): Don't count a string literal as a new
4400 (symbol_class_set): Don't count a string literal as a new token, and
4401 don't assign it a symbol number since symbol_make_alias does that.
4402 (symbol_make_alias): It's not necessary to decrement the symbol and
4403 token counts anymore. Don't assume that an alias declaration occurs
4404 before any uses of the identifier or string, and thus don't assert that
4405 one of them has the highest symbol number so far.
4406 (symbol_check_alias_consistency): Complain if there's a string literal
4407 that wasn't declared as an alias.
4408 (symbols_pack): Bail if symbol_check_alias_consistency failed since
4409 symbol_pack asserts that every token has been assigned a symbol number
4410 although undeclared string literals have not.
4411 * tests/regression.at (String alias declared after use, Undeclared
4412 string literal): New test cases.
4413 (Characters Escapes, Web2c Actions): Declare string literals as
4415 * tests/sets.at (Firsts): Likewise.
4417 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
4419 In the grammar scanner, STRING_FINISH unclosed constructs and return
4420 them to the parser in order to improve error messages.
4421 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
4422 SC_BRACED_CODE, SC_PROLOGUE): Implement.
4423 * tests/input.at (Unclosed constructs): New test case.
4424 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
4427 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
4430 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
4432 Handle string aliases for character tokens correctly.
4433 * src/symtab.c (symbol_user_token_number_set): If the token has an
4434 alias, check and set its alias's user token number instead of its own,
4435 which is set to indicate the alias. Previously, every occurrence of
4436 the character token in the grammar overwrote that alias indicator with
4438 * tests/input.at (String aliases for character tokens): New test.
4440 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
4442 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
4444 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
4446 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
4447 to prevent failures when building on older platforms.
4448 Check for autopoint failure.
4449 Set XGETTEXT_OPTIONS to values that check for C format strings,
4450 so that translators are warned about them (this also helps
4451 prevent core dumps).
4453 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
4454 function, since it simplifies our code a bit.
4456 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
4457 rather than -W, so we don't get bogus warnings about sign comparisons.
4458 Add -Wpointer-arith, since that warning is useful (it reports code
4459 that does not conform to C89 and that some compilers reject).
4460 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
4461 since it's no longer needed.
4463 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
4465 Clean up scanners a bit.
4466 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
4467 definitions so gcc won't warn when obstack_for_string is unused.
4468 * src/scan-code.l: config.h and system.h are already #include'd by
4469 scan-code-c.c, so get rid of them here.
4470 * src/scan-gram.l: Likewise.
4471 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
4472 definitions rather than duplicating the rest of it.
4473 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
4475 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
4477 Suppress signed/unsigned comparison warnings for yycheck.
4478 * data/c.m4 (b4_safest_int_type): New macro.
4479 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
4480 a signed int type, cast it to b4_safest_int_type first.
4481 * data/yacc.c: Likewise.
4482 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
4485 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
4487 * doc/bison.texinfo: Fix some typos.
4489 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
4491 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
4492 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
4494 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
4495 the latest gnulib does this a different way.
4496 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
4497 translation was patched, so stop omitting it.
4499 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
4501 Enable declaration of default %printer/%destructor. Make the parser
4502 use these for all user-declared grammar symbols for which the user does
4503 not declare a specific %printer/%destructor. Thus, the parser uses it
4504 for token 0 if the user declares it but not if Bison generates it as
4505 $end. Discussed starting at
4506 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
4507 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
4509 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
4510 * NEWS (2.3+): Mention.
4511 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
4512 declare a %destructor for a mid-rule's semantic value. It's just
4513 impossible to declare one specific to it.
4514 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
4515 code. Describe default %destructor form.
4516 * src/parse-gram.y (grammar_declaration): Parse default
4517 %printer/%destructor declarations.
4518 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
4519 and symbol_destructor_location_get rather than accessing the destructor
4520 and destructor_location members of struct symbol.
4521 (symbol_printers_output): Likewise but for %printer's.
4522 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
4524 * src/symtab.c (default_destructor, default_destructor_location,
4525 default_printer, default_printer_location): New static global
4526 variables to record the default %destructor and %printer.
4527 (symbol_destructor_get, symbol_destructor_location_get,
4528 symbol_printer_get, symbol_printer_location_get): New functions to
4529 compute the appropriate %destructor and %printer for a symbol.
4530 (default_destructor_set, default_printer_set): New functions to set the
4531 default %destructor and %printer.
4532 * src/symtab.h: Prototype all those new functions.
4533 * tests/actions.at (Default %printer and %destructor): New test to
4534 check that the right %printer and %destructor are called, that they're
4535 not called for $end, and that $$ and @$ work correctly.
4536 (Default %printer and %destructor for user-declared end token): New
4537 test to check that the default %printer and %destructor are called for
4538 a user-declared end token.
4539 * tests/input.at (Default %printer and %destructor redeclared, Unused
4540 values with default %destructor): New tests to check related grammar
4541 warnings and errors.

4545 Clean up handling of %destructor for the end token (token 0).
4546 Discussed starting at
4547 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
4549 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
4551 Make the skeletons consistent in how they pop the end token and invoke
4553 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
4554 state, which has token number 0, since this would invoke the
4555 %destructor for the end token.
4556 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
4557 until after shifting the end token, or else it won't be popped.
4558 * data/yacc.c (yyparse): Likewise.
4560 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
4561 it's the end token. Upon termination, destroy an unshifted lookahead
4562 even when it's the end token.
4563 * data/lalr1.cc (yy::parser::parse): Likewise.
4564 * data/yacc.c (yyparse): Likewise.
4566 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
4567 value warnings for the end token when the user gives the end token a
4570 * tests/actions.at (Printers and Destructors): Test all the above.
4572 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
4574 Update to latest gnulib and gettext versions.
4575 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
4577 (gnulib_files): Add m4/warning.m4. Don't worry about files
4578 overwritten by autopoint.
4579 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
4580 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
4582 Don't use autoreconf; instead, invoke autopoint etc. by hand,
4583 so that we can remove the intl files at a better time.
4584 (intl_files_to_remove): Remove aclocal.m4, since it gets
4585 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
4586 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
4587 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
4588 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
4589 Remove datarootdir hack; no longer needed.
4590 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
4591 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
4592 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
4594 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
4595 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
4597 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
4599 * bootstrap: Adjust to today's change to gnulib-tool by invoking
4600 it with --assume-autoconf='latest-stable'.
4602 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
4604 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
4605 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
4607 * src/muscle_tab.h (muscle_grow): Replace the header comments with
4608 those from muscle_tab.c since the old ones are misleading.
4610 2006-07-13 Akim Demaille <akim@epita.fr>
4612 Support %define "KEY" {VALUE}.
4613 * src/scan-code.h, src/scan-code.l (translate_action)
4614 (translate_rule_action, translate_symbol_action, translate_code):
4615 Return char *, not const char *.
4616 * src/parse-gram.y (declaration): Rename as...
4617 (prologue_declaration): this.
4618 (string_content): Remove this nonterminal, use STRING.
4619 (braceless, content, content.opt): New nonterminal.
4621 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
4623 * src/scan-gram.l (getargs.h): Don't include it.
4625 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
4627 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
4628 rather than a for-loop that declares a local bool variable. This
4629 should work around a compatibility problem with a Cray x1e C++
4630 compiler reported by Hung Nguyen in
4631 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
4632 The for-loop was introduced in the 2004-11-17 change but I don't
4633 know why it was needed.
4635 2006-07-12 Akim Demaille <akim@epita.fr>
4637 * data/c.m4: Comment changes.
4639 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
4641 * src/complain.c (error_message, ERROR_MESSAGE): New.
4643 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
4644 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
4646 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
4648 * NEWS: Instead of %union, you can define and use your own union type
4649 YYSTYPE if your grammar contains at least one <type> tag.
4650 Your YYSTYPE need not be a macro; it can be a typedef.
4651 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
4652 (Union Decl, Decl Summary): Document this.
4653 * data/glr.c (YYSTYPE): Implement this.
4654 * data/glr.cc (YYSTYPE): Likewise.
4655 * data/lalr1.cc (YYSTYPE): Likewise.
4656 * data/yacc.c (YYSTYPE): Likewise.
4657 * src/output.c (prepare): Output tag_seen_flag.
4658 * src/parse-gram.y (declaration, grammar_declaration):
4659 Use 'union_seen' rather than 'typed' to determine whether
4660 %union has been seen, since grammars can now be typed without
4662 (symbol_declaration, type.opt, symbol_def):
4663 Keep track of whether a tag has been seen.
4664 * src/reader.c (union_seen, tag_seen): New vars.
4666 * src/reader.h (union_seen, tag_seen, typed): Likewise.
4667 * src/scan-code.l (untyped_var_seen): New variable.
4668 (handle_action_dollar): Adjust to above changes.
4669 (handle_action_dollar, handle_action_at):
4670 Improve overflow checking for outlandish numbers.
4671 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
4672 avoid new diagnostics generated by above changes.
4673 * tests/regression.at (YYSTYPE typedef): Add test to check
4674 for type tags without %union.
4676 * src/symlist.c (symbol_list_length): Return int, not unsigned
4677 int, since callers expect int. This may need to get revisited
4678 once we have proper integer overflow checking.
4680 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
4681 object is now static.
4683 * src/getargs.c (flags_argmatch): Return void, not int,
4684 to pacify ./configure --enable-gcc-warnings.
4686 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
4687 since last_string is already defined to FLEX_PREFIX (last_string).
4689 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
4691 Implement --warnings/-W.
4692 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
4694 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
4696 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
4697 (warnings_args, warnings_types): New.
4698 (getargs, short_options, long_options): Accept -W/--warnings.
4699 Sort the options by alphabetical order, upper case letter right
4700 before its lower case.
4702 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
4704 Change %merge result type clash warnings to errors. Discussed at
4705 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
4706 * src/reader.c (record_merge_function_type): Use complain_at.
4707 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4708 declared later): Update test case results.
4710 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
4712 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
4713 to be in alphabetical order.
4714 (trace_args): Spelling fixes.
4716 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
4718 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
4719 so they don't collide with user-defined macros.
4720 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
4721 this was never guaranteed, and now that we're using gnulib stdint,
4722 which defines int_fast16_t to long int, the problem is exposed.
4724 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
4726 * data/c.m4 (b4_basename): Simplify a bit, since we don't
4727 need the full POSIX semantics (and weren't implementing them
4730 Adjust to Autoconf 2.60 and today's gnulib.
4731 * bootstrap (gnulib_modules): Add stdint.
4732 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
4733 no longer copies it.
4734 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
4735 since stdint needs the former and wcwidth (which is now required
4736 by mbswidth) needs the latter.
4737 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
4738 work around a compatibility glitch between gettext 0.14.6 and
4740 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
4741 Do not check for uintptr_t, since new stdint module does the right
4743 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
4744 Add stdint.h, stdint_.h, wcwidth.h.
4745 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
4746 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
4747 stdint.m4, wchar_t.m4, wcwidth.m4.
4748 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
4749 usual order for ../lib/*.h files.
4750 (file_name_split): Use last_component, not base_name, to adjust
4752 * src/parse-gram.h: Include <strverscmp.h> in the usual order
4753 for ../lib/*.h files.
4754 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
4755 Define unconditionally, since we now assume the stdint module.
4756 * src/scan-skel.l: Include <dirname.h>.
4757 (BASE_QPUTS): Use last_component, not base_name.
4758 * src/system.h: Include <unlocked-io.h> in the usual order
4759 for ../lib/*.h files. Include <stdint.h> unconditionally,
4760 since we now use the stdint module.
4761 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
4762 HAVE_UINTPTR_T, since we now use the stdint module.
4763 (base_name): Remove decl, since files now include <dirname.h>
4766 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
4768 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
4770 * data/yacc.c, data/glr.c, data/location.cc: Use them.
4771 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
4773 * tests/calc.at: Adjust.
4775 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
4777 * data/c.m4 (b4_basename): New.
4778 (b4_syncline): Also output the location of its invocation (from
4780 (b4_user_action, b4_define_user_action, b4_user_actions)
4781 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
4782 (b4_user_stype): New.
4783 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
4785 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
4787 In the grammar file, the first column is 1 not 0 on the first line as
4788 on every other line.
4789 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
4790 * tests/input.at (Torturing the Scanner): Update output.
4792 * src/scan-gram.l (scanner_cursor): Declare it static.
4794 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
4796 In warnings, say "previous declaration" rather than "first
4798 * src/symtab.c (redeclaration): Do that here.
4799 * src/reader.c (record_merge_function_type): In the case of a result
4800 type clash, report the previous declaration rather than the very first
4801 one in the grammar file.
4802 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4803 declared later): Add a third declaration to check this behavior.
4804 * tests/input.at (Incompatible Aliases): Update output.
4806 2006-06-27 Akim Demaille <akim@epita.fr>
4808 * doc/Doxyfile.in: New.
4809 * doc/Makefile.am: Use it.
4810 * src/lalr.h, src/symtab.h: Initial doxygenation.
4812 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4814 Don't miss %merge result type warnings just because the LHS types are
4815 declared after the %merge. This continues the effort of the previous
4817 * src/reader.c (get_merge_function): Don't set the merger type yet.
4818 (record_merge_function_type): New function for setting the merger type
4819 and checking for clashes.
4820 (grammar_current_rule_merge_set): Set the location of the %merge for
4822 (packgram): Invoke record_merge_function_type for each rule now that
4823 all symbol type declarations have been parsed.
4824 * src/reader.h (merger_list.type_declaration_location): New member
4825 storing the location of the first %merge from which the type for this
4826 merging function was derived.
4827 * src/symlist.h (symbol_list.merger_declaration_location): New member
4828 storing the location of a rule's %merge, if any.
4829 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4830 declared later): New test to catch the error fixed by the above patch.
4832 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4834 Get action warnings (grammar_rule_check) right even when symbol
4835 declarations appear after the rules. Discussed at
4836 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
4838 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
4839 Don't mistake the type of $$ in a midrule to be that of its parent
4841 * src/reader.c (grammar_current_rule_end): Don't invoke
4842 grammar_rule_check yet since not all symbol declarations may have been
4844 (grammar_midrule_action): Likewise.
4845 Don't record whether the midrule's $$ has been used yet since actions
4846 haven't been translated yet.
4847 Record the midrule's parent rule and its RHS index within the parent
4849 (grammar_current_rule_action_append): Don't translate the action yet
4850 since not all symbol declarations may have been parsed yet and, thus,
4851 warnings about types for $$, $n, @$, and @n can't be reported yet.
4852 (packgram): Translate the action and invoke grammar_rule_check now that
4853 all symbol declarations have been parsed.
4854 * src/scan-code.l (handle_action_dollar): Now that this is invoked
4855 after parsing the entire grammar file, the symbol list here in the case
4856 of a midrule is actually the midrule's empty RHS, so reference its
4857 parent rule's RHS where necessary.
4858 On the other hand, now that you can already know it's a midrule, you
4859 aren't forced to think $$ has the same type as its parent rule's $$.
4860 (handle_action_at): In the case of a midrule, reference the parent rule
4862 * src/symlist.c (symbol_list_new): Initialize new midrule-related
4864 (symbol_list_length): Now that this is invoked after all rules have
4865 been parsed, a NULL symbol (rather than a NULL symbol list node)
4866 terminates a rule. symbol_list_print already does this correctly.
4867 * src/symlist.h (symbol_list.midrule_parent_rule,
4868 symbol_list.midrule_parent_rhs_index): New members so that midrules can
4869 remember their relationships with their parents.
4870 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
4871 fixed by the above patch.
4872 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
4874 (Unused values): ... this old test case and...
4875 (Unused values before symbol declarations): ... this new test case.
4876 This one is the same as `Unused values' except that all symbol
4877 declarations appear after the rules in order to catch the rest of the
4878 errors fixed by the above patch.
4880 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4883 * src/reader.c (current_rule): Declare it static since it's no longer
4884 used outside this file.
4885 (grammar_current_rule_action_append): Remove redundant arguments from
4886 translate_rule_action invocation.
4887 * src/reader.h (current_rule): Remove this unused extern.
4888 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
4889 * src/scan-code.l (translate_rule_action): Likewise.
4891 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
4893 Clean up yesterday's patch.
4894 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
4896 * src/reader.c (grammar_current_rule_action_append): ... here for
4897 consistency with grammar_current_rule_symbol_append.
4898 * tests/regression.at (Braced code in declaration in rules section):
4899 Make yyerror and yylex static as usual.
4901 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
4903 Fix bug that mistakes braced code in a declaration in the rules section
4904 to be a rule action. Mentioned at
4905 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
4906 * src/scan-gram.l: Move midrule action detection from the start of the
4907 scanning of any braced code to...
4908 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
4909 action. For readability, use $2 and @2 rather than the equivalent
4911 * tests/regression.at (Braced code in declaration in rules section):
4912 New test to catch the error fixed by the above patch.
4914 Work on code readability some.
4915 * src/scan-code.l (current_rule): Get rid of this misleading and
4916 redundant declaration: it's actually extern'ed in reader.h.
4917 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
4918 translate_action): Add a rule argument and use it instead of the global
4920 (translate_rule_action): This already receives current_rule through an
4921 argument, so pass it on to translate_action instead of assigning
4922 current_rule to current_rule.
4923 (translate_symbol_action, translate_code): Pass rule = NULL to
4926 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
4928 Rename %before-definitions to %start-header and %after-definitions to
4929 %end-header. Don't use these declarations to separate pre-prologue
4930 blocks from post-prologue blocks. Add new order-independent
4931 declarations %before-header and %after-header as alternatives to the
4932 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
4933 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
4934 * NEWS (2.3+): Update for these changes.
4935 * data/glr.c (b4_before_definitions): Update to...
4936 (b4_start_header): ... this.
4937 (b4_after_definitions): Update to...
4938 (b4_end_header): ... this.
4939 * data/glr.cc: Likewise.
4940 * data/lalr1.cc: Likewise.
4941 * data/yacc.c: Likewise.
4942 * doc/bison.texinfo (The prologue): Update names, and replace remaining
4943 prologue blocks with %*-header declarations.
4944 (Calc++ Parser): Likewise.
4945 (Decl Summary): Update names.
4946 (Table of Symbols): Update description.
4947 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
4948 (PERCENT_END_HEADER): ... this.
4949 (PERCENT_BEFORE_DEFINITIONS): Update to...
4950 (PERCENT_START_HEADER): ... this.
4951 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
4952 (declaration): Update token names and m4 macro names.
4953 When parsing %end-header and %start-header, invoke translate_code
4954 before muscle_code_grow, and no longer set global booleans to remember
4955 whether these declarations have been seen.
4956 Parse new %after-header and %before-header.
4957 * src/reader.c (before_definitions, after_definitions): Remove.
4958 (prologue_augment): Accept a new bool argument to specify whether to
4959 augment the pre-prologue or post-prologue.
4960 * src/reader.h (before_definitions, after_definitions): Remove these
4962 (prologue_augment): Add new bool argument.
4963 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
4964 (PERCENT_END_HEADER): ... this.
4965 (PERCENT_BEFORE_DEFINITIONS): Update to...
4966 (PERCENT_START_HEADER): ... this.
4967 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
4968 * tests/actions.at (Printers and Destructors): Update names.
4970 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
4972 Add comparison operators for C++ location classes. Discussed at
4973 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
4974 * data/c++.m4 (b4_define_location_comparison): New boolean %define
4975 declaration indicating whether filename_type has an operator==. If
4976 filename_type is `std::string', it defaults to `1', `0' otherwise.
4977 * data/location.cc: Iff b4_define_location_comparison is `1', add
4978 operator== and operator!= for class position and for class location.
4981 * src/scan-action.l: Remove unused file.
4982 * src/symtab.c (symbol_printer_set): Use printer_location not
4983 destructor_location.
4984 * src/symtab.h (struct symbol): Replace incorrect source comment for
4986 * tests/input.at (Incompatible Aliases): Update output with correct
4989 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
4991 Don't put the pre-prologue in the header file. For the yacc.c code
4992 file and the glr.c header and code files, move the pre-prologue before
4993 the token definitions. Add new %before-definitions and
4994 %after-definitions to declare code that will go in both the header file
4995 and code file. Discussed at
4996 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,

5000 * NEWS (2.3+): Describe these changes.
5001 * data/glr.c (b4_pre_prologue): Move from within to before...
5002 (b4_shared_declarations): ... this.
5003 Add new b4_before_definitions before b4_token_enums.
5004 Add new b4_after_definitions at the end.
5005 * data/glr.cc (b4_pre_prologue): Replace with...
5006 (b4_before_definitions): ... this in the header file.
5007 (b4_after_definitions): New near the end of the header file.
5008 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
5009 code file right before including the header file.
5010 (b4_before_definitions): New in the previous position of
5011 b4_pre_prologue in the header file.
5012 (b4_after_definitions): New near the end of the header file.
5013 * data/yacc.c: Clean up some m4 quoting especially in the header file.
5014 (b4_token_enums_defines): In the code file, move to right before
5015 YYSTYPE for consistency with the header file.
5016 (b4_before_definitions): New right before b4_token_enums_defines in
5017 both the header and code file.
5018 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
5019 header and code file.
5020 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
5021 of prologues for %union dependencies.
5022 (Decl Summary): In %defines description, mention the effect of
5023 %before-definitions and %after-definitions on the header file.
5024 (Calc++ Parser): Forward declare driver in a %before-definitions rather
5025 than in the pre-prologue so that make check succeeds.
5026 (Table of Symbols): Add entries for %before-definitions and
5028 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
5029 %before-definitions.
5030 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
5031 (declaration): Parse those declarations and append to
5032 b4_before_definitions and b4_after_definitions, respectively.
5033 * src/reader.c (before_definitions, after_definitions): New bools to
5034 track whether those declarations have been seen.
5035 (prologue_augment): Add to the post-prologue if %union,
5036 %before-definitions, or %after-definitions has been seen.
5037 * src/reader.h (before_definitions, after_definitions): New extern's.
5038 * src/scan-gram.l: Scan the new declarations.
5039 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
5040 prologue block in a %before-definitions or a %after-definitions based
5041 on whether the %union is declared.
5042 * tests/regression.at (Early token definitions with --yacc, Early token
5043 definitions without --yacc): Move tests for token definitions into the
5044 post-prologue since token names are no longer defined in the
5047 2006-06-20 Akim Demaille <akim@epita.fr>
5049 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
5050 (symbol_get): Use it.
5051 * src/parse-gram.y: Use it.
5053 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
5055 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
5056 build succeeds when configured with --enable-gcc-warnings.
5058 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5060 * src/parse-gram.y (char_name): New function.
5061 (CHAR, STRING, string_content): For %printer, properly escape.
5062 (ID): Prefer fputs to fprintf.
5063 (id): Reindent to be consistent with other rules.
5064 Properly quote char.
5066 The Translation Project changed its way of publishing translations
5067 to maintainers. I haven't received any responses to my request
5068 for supporting the old way, or for documenting the new way. I
5069 have modified 'bootstrap' to use screen scraping
5070 (in this case, HTML scraping). This is unreliable and inelegant,
5071 but I don't see any better way. Yuck.
5072 * bootstrap (TP_URL, WGET_COMMAND): New vars.
5073 (get_translations): New function, which uses HTML scraping to
5074 deduce locations of latest translations.
5075 Use this function to grab both bison and bison-runtime .po files.
5076 Don't bother priming the pump for the runtime-po domain any more,
5077 as it's now translated better than bison is.
5079 2006-06-19 Akim Demaille <akim@epita.fr>
5081 * src/scan-gram.l: No longer "parse" things after `%union' until
5082 `{'. Rather, return a single "%union" token.
5083 No longer make symbols: return strings, and leave the conversion
5084 to symbols to the parser.
5085 (SC_PRE_CODE, token_type): Remove.
5086 * src/parse-gram.y (%union): New field `character'.
5089 (ID, ID_COLON): Now that the scanner no longer makes them
5090 identifiers, adjust all uses to invoke symbol_get.
5091 (id_colon): New, wraps the conversion from string to symbol.
5092 (%union): Accept a possible union_name.
5093 (symbol): Now can be a char.
5094 * data/c.m4 (b4_union_name): Leave a default value.
5095 * data/glr.c, data/yacc.c: Use it.
5097 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
5099 For associating token numbers with token names for "yacc.c", don't use
5100 #define statements unless `--yacc' is specified; always use enum
5101 yytokentype. Most important discussions start at:
5102 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
5103 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
5105 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
5106 * NEWS (2.3+): Mention.
5107 * data/c.m4 (b4_yacc_if): New.
5108 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
5110 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
5111 on token name definitions.
5112 * src/getargs.c (usage): Capitalize `Yacc' in English.
5113 * src/output.c (prepare): Define b4_yacc_flag.
5114 * tests/regression.at (Early token definitions): Test that tokens names
5115 are defined before the pre-prologue not just before the post-prologue.
5116 Remove this test case and copy to...
5117 (Early token definitions with --yacc): ... this to test #define's.
5118 (Early token definitions without --yacc): ... and this to test enums.
5120 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
5122 * NEWS: Reword the post-2.3 change to not be so optimistic about
5123 removing the old "look-ahead" spelling.
5124 Update previous look-ahead/lookahead change reports.
5125 * REFERENCES: look-ahead -> lookahead (since that's
5126 what he actually wrote).
5127 * doc/refcard.tex: look ahead -> lookahead,
5128 look-ahead -> lookahead
5130 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
5132 For consistency, use `lookahead' instead of `look-ahead' or
5133 `look_ahead'. Discussed starting at
5134 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>

5166 * src/print.c: Update English in comments.
5167 (lookahead_set): Rename from look_ahead_set.

5203 2006-06-08 Joel E. Denny <jdenny@ces.clemson.edu>
5205 * src/flex-scanner.h (yytext): Remove stray `*/' in #define.
5207 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5209 * TODO: Add request from Nelson H. F. Beebe to be able to install
5210 Bison without installing the yacc script.
5212 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
5214 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
5215 and yytext if they're already #define'd.
5216 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
5217 * src/scan-code-c.c: ... here.
5218 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include
5221 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
5223 Get Bison to build again when configured with --enable-gcc-warnings.
5224 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
5226 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
5227 loc argument as it shadows a global.
5228 * src/scan-gram.l: Remove stray comma that prevents boundary_set
5231 * src/.cvsignore: Add scan-code.c.
5233 2006-06-07 Akim Demaille <akim@epita.fr>
5235 * src/scan-gram.l: Move the "add a trailing ; to actions" code
5237 * src/scan-code.l: here.
5238 * tests/input.at (Torturing the Scanner): Fix another location
5241 2006-06-07 Akim Demaille <akim@epita.fr>
5243 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
5245 2006-06-06 Akim Demaille <akim@epita.fr>
5247 Extract the parsing of user actions from the grammar scanner.
5248 As a consequence, the relation between the grammar scanner and
5249 parser is much simpler. We can also split "composite tokens" back
5251 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
5252 * src/scan-gram.l (add_column_width, adjust_location): Move to and
5254 * src/location.h, src/location.c (add_column_width)
5255 (location_compute): these.
5256 Fix the column count: the initial column is 0.
5257 (location_print): Be robust to ending column being 0.
5258 * src/location.h (boundary_set): New.
5259 * src/main.c: Adjust to scanner_free being renamed as
5261 * src/output.c: Include scan-code.h.
5262 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
5264 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
5265 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
5266 which is now, again, a separate token.
5267 Adjust all dependencies.
5268 Whereever actions with $ and @ are used, use translate_code.
5269 (action): Remove this nonterminal which is now useless.
5270 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
5271 (grammar_current_rule_action_append): Use translate_code.
5272 (packgram): Bound check ruleno, itemno, and rule_length.

5274 (last_string, last_braced_code_loc, max_left_semantic_context)
5275 (scanner_initialize, scanner_free, scanner_last_string_free)
5276 (gram_out, gram_lineno, YY_DECL_): Move to...
5277 * src/scan-gram.h: this new file.
5278 (YY_DECL): Rename as...
5280 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
5281 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
5282 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
5283 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
5284 Move these declarations, and...
5285 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
5287 * src/flex-scanner.h: this new file.
5288 * src/scan-gram.l (rule_length, rule_length_overflow)
5289 (increment_rule_length): Remove.
5290 (last_braced_code_loc): Rename as...
5291 (gram_last_braced_code_loc): this.
5292 Adjust to the changes of the parser.
5293 Move all the handling of $ and @ into...
5294 * src/scan-code.l: here.
5295 * src/scan-gram.l (handle_dollar, handle_at): Remove.
5296 (handle_action_dollar, handle_action_at): Move to...
5297 * src/scan-code.l: here.

5308 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
5310 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
5311 Use Akim's wording from
5312 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
5314 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
5316 Between Bison releases, manually append `+' to the previous Bison
5317 release number, and use that as a signal to automatically print the
5318 ChangeLog's CVS Id keyword from --version. Discussed starting at
5319 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
5320 * ChangeLog: Add Id header.
5321 * configure.ac (AC_INIT): Append `+' to `2.3'.
5322 * src/.cvsignore: Add revision.c.
5323 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
5324 (BUILT_SOURCES): Add revision.c.
5325 (revision.c): New target rule. This file defines a new global variable
5326 named revision. It initializes it with either the Id from ChangeLog
5327 or, if VERSION doesn't contain `+', with the empty string.
5328 * src/getargs.c (version): Print the value of revision.
5329 * src/revision.h: Extern revision.
5331 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5333 * NEWS: Version 2.3.
5334 * configure.ac (AC_INIT): Likewise.
5336 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5338 * data/glr.c (YYRECOVERING): Define to be a function-like macro
5339 with no arguments, not as an object-like macro. This is for
5340 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
5341 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
5342 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
5345 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
5347 * src/getargs.c (usage): Back out yesterday's modification of the
5348 --help output so that we don't have to wait for translation before
5351 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5353 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
5354 Problem reported by Akim Demaille.
5356 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
5358 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
5360 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5362 * data/yacc.c (yy_reduce_print): Omit trailing white space in
5363 generated source code. Problem reported by Frans Englich in
5364 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
5366 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
5368 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
5369 shell, not within 'make', so that 'make' by an ordinary builder
5370 (using GNU make) does not worry about configuring gzip. This also
5371 works around a bug reported independently by Keith Thompson and by
5372 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
5373 stderr rather than stdout, messing up the build logs.
5375 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
5377 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
5378 to make sure that YYID will never be unused. This fixes a 'make
5379 maintainer-check' failure caused by the recent changes to the 'Trivial
5380 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
5382 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
5384 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
5386 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
5387 state before an empty RHS is always resolved here. Only the location
5388 of that state is guaranteed to be resolved, and that's enough. This
5389 fixes the remaining bug reported by Derek M. Jones in
5390 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
5391 * tests/glr-regression.at (Uninitialized location when reporting
5392 ambiguity): Test the above case.
5393 Also, the embedded comments in this test case claim it checks the case
5394 of an empty RHS that has inherited the initial location. However, the
5395 corresponding LHS was already resolved, so yyresolveLocations didn't
5396 actually have reason to modify it. Fix this by forcing
5397 nondeterministic operation at the beginning of the parse.
5399 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5401 * data/c.m4 (b4_yy_symbol_print_generate):
5402 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
5403 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
5404 of the bugs reported today by Derek M Jones in
5405 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
5406 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
5407 defined to be a type name without parens or brackets.
5408 (Location Type): Similarly for YYLTYPE.
5409 * tests/regression.at (Trivial grammars): Put in a test for this
5410 bug that will be caught by 'make maintainer-check' (though not,
5411 alas, by 'make check' unless your compiler is picky).
5413 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5415 * NEWS: Version 2.2.
5416 * configure.ac (AC_INIT): Likewise.
5418 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
5420 * data/glr.c (yyreportTree): Make room in yystates for the state
5421 preceding the RHS. This fixes the segmentation fault reported by Derek
5423 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
5424 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
5425 to the user. Reported for yyreportTree by Derek M. Jones later in the
5427 * THANKS: Add Derek M. Jones.
5428 Update my email address.
5429 Fix typo in Steve Murphy's name.
5431 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5433 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
5434 checking against YYLAST that caused the parser to miss a potential
5435 alternative in its diagnostic.
5436 Problem reported by Maria Jose Moron Fernandez in
5437 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
5438 * data/lalr1.cc (yysyntax_error_): Likewise.
5439 * data/yacc.c (yysyntax_error): Likewise.
5440 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
5441 tokens, in case we run into an older C compiler.
5442 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
5443 Use them to check for the off-by-one error fixed above.
5445 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
5446 YYSIZE_T, not size_t.
5447 * tests/regression.at (Trivial grammars): New test, to catch
5448 the error fixed by the above patch.
5450 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5452 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
5454 Reported by Steve Murphy.
5456 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5458 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
5459 * data/glr.cc: b4_location_flag is now b4_locations_flag.
5461 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5463 Implement --trace=m4.
5464 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
5465 * src/output.c (output_skeleton): When set, pass -dV to m4.
5467 Factor the handling of flags in m4.
5468 * src/output.c (prepare): Rename the muscle names debug, defines,
5469 error_verbose to debug_flag, defines_flag, error_verbose_flag.
5470 * data/c.m4: Adjust.
5471 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
5472 Use b4_define_flag_if to define other b4_FLAG_if macros.
5473 (b4_location_if): As a consequence, rename as...
5474 (b4_locations_if): this, for consistency.
5475 Adjust all the skeletons.
5477 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5479 * etc/bench.pm: Shorten bench names.
5481 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5483 * src/output.h, src/output.c (error_verbose): Move to...
5484 * src/getargs.h, src/getargs.c: here.
5486 Adjust dependencies.
5488 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5490 * data/c.m4 (b4_copyright): Put the special exception for Bison
5491 skeletons here, so we don't have to put it in each skeleton. All
5492 uses changed. Suggested by Akim Demaille. Also, wrap the
5493 copyright notice, in case it is longer than 80 columns. Replace
5494 comma by newline after title.
5496 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5498 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
5499 incompatibility, not a bug. Mention that it wasn't fixed as of
5502 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
5504 * examples/extexi: Enforce the precedence of concatenation over
5506 Reported by Tommy Nordgren.
5508 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
5510 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
5511 with the member "token".
5512 Reported by Martin Nylin.
5514 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
5516 * data/glr.c: Switch to Bison 2.2 special-exception language in
5517 the copyright notice. Use more-regular format for titles and
5519 * data/glr.cc: Likewise.
5520 * data/location.cc: Likewise.
5521 * data/yacc.cc: Likewise.
5522 * doc/bison.texinfo (Conditions): Document this.
5523 * NEWS: likewise. Upgrade version to 2.2.
5525 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
5527 * data/glr.cc: Remove dead code.
5529 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5531 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
5532 that variable and the line breaks the bootstrap. Problem reported
5533 by Juan M. Guerrero.
5535 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
5537 * doc/bison.texinfo (Multiple start-symbols): New.
5539 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
5541 * etc/README, etc/bench.pl: New.
5543 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
5545 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
5547 Reported by Mickael Labau.
5548 * tests/input.at (Torturing the Scanner): Test it.
5550 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
5552 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
5553 Problem reported by Bob Rossi.
5555 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
5557 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
5558 and didn't really work.
5559 For the index, use @ifnotinfo, not @iftex.
5560 Minor cleanups of spacing and terminology.
5562 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
5564 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
5565 of AT_NAME_PREFIX when %name-prefix is not used.
5567 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
5569 Apply --prefix to C++ skeletons too: they change the namespace.
5570 The test suite already exercize these cases.
5571 * data/c++.m4 (b4_namespace): New.
5572 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
5573 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
5574 * data/yacc.c, data/glr.c: Remove a useless `[]'.
5575 * doc/bison.texinfo: Document it.
5576 (Option Cross Key): Use @multitable in all formats. It looks
5577 nicer, even in TeX outputs.
5578 (Rules): Use the same code whatever the output type is.
5579 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
5580 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
5581 * tests/calc.at: Use it, instead of hard coding `yy'.
5583 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
5585 * TODO: Remove dead items.
5587 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
5589 * doc/FAQ: Remove, merged into...
5590 * doc/bison.texinfo (FAQ): this.
5591 * doc/Makefile.am (EXTRA_DIST): Adjust.
5593 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
5595 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
5597 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
5598 * doc/bison.texinfo (Calc++ Scanner): Use it.
5600 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
5602 Fix two nits reported by twlevo, plus one more that I discovered.
5604 * src/assoc.h (assoc_to_string): Give a name to the arg, as
5605 this is the usual Bison style.
5606 * src/location.h (location_print): Likewise.
5608 * src/reader.h (token_name): Likewise.
5610 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
5612 Fix some nits reported by twlevo.
5613 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
5614 and "POSIX". Use more-modern syntax for URLs. Mention C++
5615 and ask for Java. Don't hardwire OS version numbers. Add
5617 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
5618 * src/conflicts.c (solved_conflicts_obstack): Now static.
5620 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
5622 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
5623 page. Say "you can use it" not "you may use it" as on the web page;
5624 we're describing capabilities not granting permission.
5626 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
5628 * data/glr.c (yyresolveLocations): Rename local variables to avoid
5629 shadowing warnings. Use usual patter for iterating through RHS.
5630 * tests/glr-regression.at
5631 (Uninitialized location when reporting ambiguity):
5632 Modify yylex so that it uses its argument, rather than trying
5633 to rely on ARGSUSED (which doesn't work for gcc with warnings).
5634 const char -> char const.
5636 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
5637 Don't use tabs inside commands; it messes up 'ps'.
5638 Problem reported by twlevo.
5640 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
5642 * tests/glr-regression.at (Uninitialized location when reporting
5643 ambiguity): New test case.
5644 * data/glr.c (yyresolveLocations): New function, which uses
5646 (yyresolveValue): Invoke yyresolveLocations before reporting an
5648 * doc/bison.texinfo (Default Action for Locations): Note
5649 YYLLOC_DEFAULT's usage for ambiguity locations.
5650 (GLR Semantic Actions): Cross-reference those notes.
5652 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
5654 * tests/glr-regression.at (Leaked semantic values when reporting
5655 ambiguity): Remove unnecessary union and type declarations.
5656 (Leaked lookahead after nondeterministic parse syntax error): New test
5658 * data/glr.c (yyparse): Check for zero stacks remaining before
5659 attempting to shift the lookahead so that you don't lose it.
5661 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
5663 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
5664 * tests/glr-regression.at (Leaked semantic values when reporting
5665 ambiguity): New test case.
5666 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
5667 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
5668 now unnecessary yystackp parameter.
5669 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
5670 destructors can be called.
5672 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
5673 in existing testcases.
5675 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
5677 Don't leak semantic values for parent RHS when a user action cuts the
5678 parser, and clean up related code a bit.
5679 * tests/glr-regression.at (Leaked merged semantic value if user action
5680 cuts parse): Rename to...
5681 (Leaked semantic values if user action cuts parse): ... this. Add check
5682 for leaked parent RHS values.
5683 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
5684 between an unresolved state (non-empty chain of semantic options) and
5685 an incomplete one (signaled by an empty chain).
5686 (yyresolveStates): Document the interface. Move all manipulation of a
5687 successfully or unsuccessfully resolved yyGLRState to...
5688 (yyresolveValue): ... here so that yyresolveValue always leaves a
5689 yyGLRState with consistent data and thus is easier to understand.
5690 Remove the yyvalp and yylocp parameters since they are always just
5691 taken from the yys parameter. When reporting a discarded merged value
5692 in debugging output, note that it is incompletely merged. Document the
5694 (yyresolveAction): If resolving any of the RHS states fails, destroy
5695 them all rather than leaking them. Thus, as long as user actions are
5696 written to clean up the RHS correctly, yyresolveAction always cleans up
5697 the RHS of a semantic option. Document the interface.
5699 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
5701 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
5702 led to a segmentation fault in GNU Pascal. Problem reported
5705 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
5707 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
5708 mid-rule action inside a nonterminal symbol in order to declare a
5709 destructor for its semantic value.
5711 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>
5713 * data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !
5714 YYSTACK_USE_ALLOCA && ! defined YYSTACK_ALLOC && defined
5715 __cplusplus && ! defined _STDLIB_H && !
5716 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
5717 defined free))]: Include <stdlib.h> rather than rolling our own
5718 declarations of malloc and free, to avoid problems with
5719 incompatible declarations (using 'throw') C++'s stdlib.h. This
5720 should fix Debian bug 340012
5721 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=340012>,
5722 reported by Guillaume Melquiond.

5726 * NEWS: Clarify symbols versus types in unused-value warnings.
5728 * configure.ac (AC_INIT): Bump version number.
5730 2006-02-13 Paul Eggert <eggert@cs.ucla.edu>
5732 * NEWS: Version 2.1a.
5733 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
5734 since C99 requires this.
5736 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
5738 * m4/c-working.m4: New file.
5739 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
5741 2006-02-10 Paul Eggert <eggert@cs.ucla.edu>
5743 * Makefile.maint: Merge from coreutils.
5745 2006-02-09 Paul Eggert <eggert@cs.ucla.edu>
5747 More portability fixes for problems summarized by Nelson H. F. Beebe.
5749 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
5750 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
5751 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
5752 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this
5753 messes up because C++ code is compiled in 32-bit mode but linked

5758 More portability fixes for problems summarized by Nelson H. F. Beebe.
5760 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
5761 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
5763 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
5764 nodist_PROGRAMS, since we don't need to actually compile the
5765 example if we're just doing a plain 'make'. This avoids bothering
5766 the installer unnecessarily about problems due to weird C++
5769 2006-02-06 Paul Eggert <eggert@cs.ucla.edu>
5771 More portability fixes for problems summarized by Nelson H. F. Beebe.
5773 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
5774 than #include "...", and compile with -I'.'. The old method was
5775 not portable, according to Posix and the C standard, and it does
5776 not work with Sun C 5.7, where previous #line directives affect
5777 the working directory used in later #include "..." directives.

5787 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check that
5788 '#include <map>' works and that you can apply ++ to iterators.
5790 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
5792 Work around portability problems summarized by Nelson H. F. Beebe in

5795 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
5796 that '#include <string>' works.
5798 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
5799 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
5800 "warning: sorry: semantics of inline function static data `const
5801 unsigned char translate_table[262]' are wrong (you'll wind up with
5804 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
5805 or, xor to not_, and_, or_, and xor_, respectively. This works
5806 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
5807 random system header somewhere that includes the equivalent of
5810 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
5811 -E" works; it apparently doesn't work with PathScale EKO Compiler
5814 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
5816 During deterministic GLR operation, user actions should be able to
5817 influence the parse by changing yychar. To make this easier to fix and
5818 to make glr.c easier to evolve in general, don't maintain yytoken in
5819 parallel with yychar; just compute yytoken when needed.
5820 * tests/glr-regression.at (Incorrect lookahead during deterministic
5821 GLR): Check that setting yychar in a user action has the intended
5823 * data/glr.c (yyGLRStack): Remove yytokenp member.
5824 (yyclearin): Don't set *yytokenp.
5825 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
5826 yychar rather than *yytokenp to determine the current lookahead.
5827 Compute yytoken locally when needed.
5828 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
5831 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
5832 after `--report' documentation.

5836 * src/parse-gram.y (grammar_declaration): Location of printer
5837 symbol is @1, not list->location. Bug reported by twlevo.

5840 2006-01-29 Paul Eggert <eggert@cs.ucla.edu>
5842 * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do
5843 all the test at once. This makes the output easier to read in the
5846 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
5847 got from <http://bro-ids.org/download.html>. The bug is that
5848 when two actions appeared in succession, the second one was
5849 scanned before the first one was added to the grammar rule
5850 as a midrule action. Bison then output the incorrect warning
5851 "parse.y:905.17-906.36: warning: unused value: $3".
5852 * src/parse-gram.y (BRACED_CODE, action): These are no longer
5853 associated with a value.
5854 (rhs): Don't invoke grammar_current_rule_action_append.
5855 (action): Invoke it here instead.
5856 * src/reader.c (grammar_midrule_action): Now extern.
5857 (grammar_current_rule_action_append): Don't invoke
5858 grammar_midrule_action; that is now the scanner's job.
5859 * src/reader.h (last_string, last_braced_code_loc):
5860 (grammar_midrule_action): New decls.
5861 * src/scan-gram.l (last_string): Now extern, sigh.
5862 (last_braced_code_loc): New extern variable.
5863 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
5864 rule already has an action.
5865 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
5866 * tests/input.at (AT_CHECK_UNUSED_VALUES):
5867 Add some tests to check that the above changes fixed the bug.
5869 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
5871 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
5872 All used changed. Check whether the symbol has a destructor,
5873 not whether it is typed.
5874 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
5875 that the values are still reported as unused. All line numbers

5889 Work around a bug in Pike 7.0, and give the Pike folks a
5890 better way to override the usual int widths.
5891 * data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the
5892 user can override the types.
5893 (short): #undef, to work around a bug in Pike 7.0.
5894 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
5895 (union yyalloc.yyss): Use yytype_int16 rather than short.
5897 (yysigned_char): Remove.
5898 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
5899 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.
5900 * tests/regression.at (Web2c Actions): Adjust to above changes.
5902 * src/reader.c (check_and_convert_grammar): New function.
5903 (reader): Close the input file even if something went wrong during
5904 parsing. Minor file descriptor leak reported by twlevo.
5906 * src/assoc.c (assoc_to_string): Use a default: abort (); case
5907 to pacify gcc -Wswitch-default.
5908 * src/scan-gram.l (adjust_location): Use a default: break; case
5909 to pacify gcc -Wswitch-default.
5910 * src/scan-skel.h (skel_get_lineno, skel_get_in, skel_get_out):
5911 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
5912 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
5913 Move these decls to scan-skel.l, since they don't need to be
5915 * src/scan-skel.l: Accept the above decls.
5916 (skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31
5919 2006-01-21 Paul Eggert <eggert@cs.ucla.edu>
5921 * Makefile.cfg (local-checks-to-skip): Add changelog-check,

6113 in the yychar entry.
6114 In the yychar entry, remove mention of the local yychar case (pure
6115 parser) since this is irrelevant information when writing semantic
6116 actions and since it's already discussed in `Table of Symbols' where
6117 yychar is otherwise described as an external variable.
6118 In the yychar entry, don't call it the `current' look-ahead since it
6119 isn't when semantic actions are deferred.
6120 In the yychar and yyclearin entries, add note about deferred semantic
6122 Add yylloc and yylval entries discussing look-ahead usage.
6123 (Look-Ahead Tokens): When discussing yychar, don't call it the

6144 appropriately during nondeterministic operation.
6145 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
6146 members to store the current lookahead to be used by the deferred
6148 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
6149 from which the RHS is taken. Set the lookahead members of the new
6150 yySemanticOption according to the lookahead status for stack yyk.

6152 yyaddDeferredAction.
6153 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead

6162 char value < 128 in main.
6163 (Incorrect lookahead during deterministic GLR): New test case.
6164 (Incorrect lookahead during nondeterministic GLR): New test case.
6166 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
6168 * data/c.m4 (b4_yy_symbol_print_generate): In yy_symbol_print, accept

6178 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
6180 * data/glr.c (yyresolveValue): When merging semantic options, if at
6181 least one user action succeeds but a later one cuts the parse, then
6182 destroy the semantic value before returning rather than leaking it.
6183 (yyresolveStates): If a user action cuts the parse and thus
6184 yyresolveValue fails, ignore the (unset) semantic value rather than
6185 corrupting the yyGLRState, and empty the semantic options list since
6186 the user actions should have called all necessary destructors.
6187 Simplify code with YYCHK.
6188 * tests/glr-regression.at (Corrupted semantic options if user action
6189 cuts parse): New test case.
6190 (Undesirable destructors if user action cuts parse): New test case.
6191 Before applying any of this patch, this test case never actually failed
6192 for me... but only because the corrupted semantic options usually

6236 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain

6244 * src/symtab.h (struct symbol.declared): New member.
6245 * src/symtab.c (symbol_new): Initialize it to false.
6246 (symbol_class_set): New arg DECLARING, specifying whether

6387 Undo 2005-12-01 tentative license wording change. The wording is
6388 still being reviewed by the lawyers, and we don't want to wait for
6389 them before publishing a test release. For now, revert to the

6405 for consistency. Fix some spelling errors and reword recently-included
6407 * tests/cxx-type.at: Cast results of malloc, for C++.
6409 2005-12-21 Joel E. Denny <address@hidden>
6411 * tests/cxx-type.at: Construct a tree, count the parents of shared
6412 nodes, and free each node once and only once. Previously, the memory
6413 for semantic values was leaked instead.
6415 2005-12-21 Joel E. Denny <address@hidden>
6417 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.
6418 (yylval, yylloc): If pure, #define to yystackp->yyval and
6419 yystackp->yyloc similar to yychar and yynerrs.
6420 (yyparse): If pure, remove local yylval and yylloc. Add local

6429 accessible through yystackp. If not pure, they are still accessible

6432 `if (YYID (N))' to pacify lint.
6434 2005-12-21 Akim Demaille <akim@epita.fr>
6436 YYACCEPT, YYERROR, and YYABORT, as user actions, should not
6437 destroy the RHS symbols of a rule.
6438 * data/yacc.c (yylen): Initialize to 0.
6439 Keep its value to the number of items to possibly shift.
6440 In particular, a regular successful parse that ends on YYFINAL by
6441 a (internal) YYACCEPT must not have yylen != 0.
6442 (yyerrorlab, yyreturn): Pop the RHS.
6443 Reorder a bit to emphasize the `shifting' bits of code.

6454 * djgpp/config.bat: Replace every occurence of the file name
6455 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
6456 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
6457 * djgpp/config.sed: Replace every occurence of the file name
6458 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

6488 sed out the final state number.
6490 Work around portability problem on Solaris 10: flex-generated
6491 files include <stdio.h> before <config.h>, which messes up
6492 because the latter defines __EXTENSIONS__. Address the problem
6493 by creating two new little files that include <config.h> first,
6494 then include the flex-generated files. Rewrite everyone else
6495 to include <config.h> first, as well.
6496 * lib/timevar.c: Always include "config.h".
6497 * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with

6538 definition if 'lint' is defined.
6539 (YYID): New macro (or function, if lint).
6540 All uses of /*CONSTCOND*/0 replaced by YYID(0).
6541 * data/yacc.c: Likewise.
6542 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
6543 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
6544 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
6546 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
6547 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
6548 Use YYID(0) rather than 0, for lint.
6549 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
6550 (yysyntax_error): Rewrite to avoid lint warnings about parenthesization.

6570 * NEWS: Document the following change.
6571 * data/yacc.c: Say "parser skeleton" rather than "file", since
6572 it's no longer just a file.
6573 * data/glr.c: Grant a special exception for C GLR parsers, that
6574 reads like the already-existing exception for C LALR(1) parsers.

6576 * data/lalr1.cc: Likewise.
6577 * data/location.cc: Likewise.

6861 * data/lalr1.cc (yysymprint_, yydestruct_): Use a call to suppress
6862 unused-variable warnings.
6864 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>
6866 * Makefile.am: DJGPP specific files added to EXTRA_DIST.
6868 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
6870 Use unlocked I/O for a minor performance improvement on hosts like
6871 GNU/Linux and Solaris that support unlocked I/O. The basic idea
6872 is to use the gnlib unlocked-io module, and to prefer putc and
6873 puts to printf when either will work (since the latter doesn't
6874 come in an unlocked flavor).
6875 * bootstrap (gnulib_modules): Add unlocked-io.
6876 * data/c.m4 (yysymprint): Prefer puts and putc to printf.
6877 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.

6889 * src/output.c (escaped_output): Likewise.
6890 (user_actions_output): Coalesce two printfs.
6891 * src/parse-gram.y (%printer): Prefer putc and puts to printf.
6892 * src/reduce.c (reduce_print): Likewise.
6893 * src/state.c (state_rule_look_ahead_tokens_print): Likewise.
6894 * src/system.h: Include unlocked-io.h rather than stdio.h.
6896 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as
6897 this confuses xgettext.

6922 (spec_defines_file): Now const.
6924 (short_base_name): Remove.
6925 * src/files.c: Adjust.

6937 * src/scan-skel.l (@dir_prefix@): New.
6939 2005-10-02 Juan Manuel Guerrero <juan.guerrero@gmx.de>
6941 * lib/subpipe.c: New function end_of_output_subpipe() added
6942 to allow support for non-posix systems. This is a no-op function
6945 * lib/subpipe.h: New function end_of_output_subpipe() added
6946 to allow support for non-posix systems. This is a no-op function
6949 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
6950 handle the lack of pipe/fork functionality on non-posix systems.
6952 * djgpp/Makefile.maint: DJGPP specific file.
6954 * djgpp/README.in: DJGPP specific file.
6956 * djgpp/config.bat: DJGPP specific configuration file.
6958 * djgpp/config.sed: DJGPP specific configuration file.

6971 * data/lalr1.cc: here.
6972 (location.hh): Include it after the user prologue, in case the
6973 filename type is defined by the user.
6974 Forward declation location and position before the pre-prologue.
6975 (yyresult_): Rename as...
6976 (yyresult): this, it's a local variable, not an attribute.
6977 * data/Makefile.am (dist_pkgdata_DATA): Adjust.
6979 2005-10-01 Akim Demaille <akim@epita.fr>
6981 * examples/extexi: Restore the #line generation.
6983 2005-09-30 Akim Demaille <akim@epita.fr>,
6984 Alexandre Duret-Lutz <adl@gnu.org>
6986 Move the token type and YYSTYPE in the parser class.
6987 * data/lalr1.cc (stack.hh, location.hh): Include earlier.
6988 (parser::token): New, from the moved free definition of tokens.
6989 (parser::semantic_value): Now a full definition instead of an
6990 indirection to YYSTYPE.
6991 (b4_post_prologue): No longer included in the header file, but
6992 in the implementation file.
6993 * doc/bison.texi (C+ Language Interface): Update.
6994 * src/parse-gram.y: Support unary %define.
6995 * tests/actions.at: Define global_tokens_and_yystype for backward

6999 to simplify the code.
7001 2005-09-29 Paul Eggert <eggert@cs.ucla.edu>
7003 Port to SunOS 4.1.4, which lacks strtoul and strerror.
7004 Ah, the good old days! Problem reported by Peter Klein.

7018 (yysyntax_error_): Takes the state number as argument.
7019 (yyreduce_print_): Use the argument yyrule, not the former
7022 2005-09-26 Paul Eggert <eggert@cs.ucla.edu>
7024 * bootstrap (gnulib_modules): Add verify.
7025 * lib/.cvsignore: Add verify.h.

7034 local variables whose names begin with 'yy'.
7035 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
7036 Trivial changes from Joel E. Denny.
7038 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
7040 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
7041 don't use alloca any more.
7043 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
7044 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
7045 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
7046 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
7047 to match yacc.c, to test more hosts.
7049 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
7051 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
7052 doesn't affect behavior.
7053 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
7055 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
7056 This works a bit better with glibc, if user code has already included
7058 * doc/bison.texinfo (Bison Parser): Document that users can't
7059 arbitrarily use malloc and free for other purposes. Document
7060 that <alloca.h> and <malloc.h> might be included.

7071 2005-09-19 Paul Eggert <eggert@cs.ucla.edu>
7073 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
7074 (YYSTACK_ALLOC_MAXIMUM): Use it.
7075 (yysyntax_error): New function.
7076 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
7077 multiple syntax errors are reported, and alloca is being used.
7078 Instead, reallocate buffers twice as big each time, so that
7079 we waste at most half the allocated memory. Start with a small
7080 (128-byte) buffer that will suffice in most cases anyway.
7081 Use yysyntax_error to do most of the work.
7083 * doc/bison.texinfo (Error Reporting, Table of Symbols):
7084 yynerrs is the number of errors reported, not the number of
7087 * tests/glr-regression.at (Duplicated user destructor for lookahead):
7088 Mark it as expected to fail.
7089 Cast result of malloc; problem reported by twlevo@xs4all.nl.
7090 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
7091 Don't start user-code symbols with "yy", to avoid name space problems.
7093 2005-09-19 Akim Demaille <akim@epita.fr>
7095 Remove the traits, failed experiment.
7096 It never proved useful, and anyway because of the current
7097 definition, it was not possible to have several specialization of
7098 this traits, making it useless.
7099 * data/lalr1.cc (yy:traits): Remove.
7100 Inline its definitions in the parser class.
7102 2005-09-19 Akim Demaille <akim@epita.fr>
7104 * tests/atlocal.in (LIBS): Pass INTLLIBS to address failures on at

7122 * data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing
7124 * src/output.c (prepare): Likewise.
7125 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
7126 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
7127 is not defined. This is an awful hack, but it's enough for now.
7128 All callers changed.
7129 * tests/glr-regression-at (make_value): Args are const pointers now,
7130 to avoid GCC warning.
7131 (Duplicated user destructor for lookahead): New test. Currently
7132 skipped. It fails on my host but I'm not sure it'll always fail.
7134 2005-09-16 Akim Demaille <akim@epita.fr>
7136 * src/symtab.h (struct symbol): Declare the printer and destructor
7137 as const, to avoid accidental calls to free.
7138 (symbol_destructor_set, symbol_printer_set): Adjust.
7139 * src/symtab.c: Adjust.
7141 2005-09-16 Akim Demaille <akim@epita.fr>
7143 * data/c.m4 (b4_token_enums): New.
7144 (b4_token_defines): Rename as...
7145 (b4_token_enums_defines): this.
7146 (b4_token_defines): New, output only the #defines.
7147 * data/yacc.c, data/glr.c: Adjust.
7148 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
7149 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
7152 2005-09-16 Akim Demaille <akim@epita.fr>
7154 * data/lalr1.cc (yylex_): Remove, inline its code.
7155 (yyreport_syntax_error_): Remove, replaced by...
7156 (yysyntax_error_): this which returns a string and leaves to the
7157 caller the call to the users' error function.
7158 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
7159 Move from members of the parser object...
7160 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
7161 to local variables of the parse function.
7163 2005-09-16 Akim Demaille <akim@epita.fr>
7165 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
7166 since it's in Bison's name space.
7168 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
7170 * data/glr.c (yyresolveValue): Add default case to pacify
7171 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
7173 * NEWS: Document when yyparse started to return 2.
7174 * doc/bison.texinfo (Parser Function): Document when yyparse
7177 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
7178 (b4_filename_type): Renamed back from b4_file_name_type. All uses
7180 (class position): file_name -> filename (reverting). All uses changed.
7182 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
7184 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
7185 do anything if $@ exists. This reverts part of the 2005-07-07
7188 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
7190 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
7191 contains obsolete information and isn't worth distributing as a
7192 separate file anyway.
7193 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
7194 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
7195 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
7196 (yyparse): Abort if user code uses longjmp to throw an unexpected
7199 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
7201 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
7202 Suggested by twlevo@xs4all.nl.
7204 * data/glr.c (YYCHK1): Do not assume YYE is in range.
7205 This avoids a diagnostic from gcc -Wswitch-enum.
7206 Problem reported by twlevo@xs4all.nl.
7208 * doc/bison.texinfo: Don't use "filename", as per GNU coding
7209 standards. Use "file name" or "file" or "name", depending on
7211 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
7212 not to hack/foo.tab.c.
7213 (Calc++ Top Level): 2nd arg of main is not const.
7214 * data/glr.c: b4_filename -> b4_file_name.
7215 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.
7217 (class position): filename -> file_name. All uses changed.

7224 * src/muscle_tab.c (muscle_init): Output b4_file_name, not b4_filename.
7226 2005-09-08 Paul Eggert <eggert@cs.ucla.edu>
7228 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
7229 to accommodate latest gnulib.
7231 * tests/glr-regression.at (Duplicate representation of merged trees):
7232 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
7234 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
7237 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7239 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
7240 All uses changed. Invoke user destructor after an error during a
7241 split parse (trivial change from Joel E. Denny).
7243 * tests/glr-regression.at
7244 (User destructor after an error during a split parse): New test case.
7245 Problem reported by Joel E. Denny in:
7246 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
7248 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7250 * README-cvs: Give URLs for recommended tools.
7251 Mention Gzip version problem, and bootstrapping issues.
7252 Remove troubleshooting section, as it's somewhat obsolete.
7254 * bootstrap (no_cache): New var, to accommodate different wget
7255 variants. Use it instead of '-C off'. Problem reported by
7258 * data/glr.c (yydestroyStackItem): New function.
7259 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
7260 debugging information. Problem reported by Joel E. Denny.
7262 2005-08-25 Akim Demaille <akim@epita.fr>
7264 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
7266 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>
7268 * data/glr.c (yyrecoverSyntaxError, yyreturn):
7269 Don't invoke destructor on unresolved entries.
7270 * tests/glr-regression.at
7271 (User destructor for unresolved GLR semantic value): New test case.
7272 Problem reported by Joel E. Denny in:
7273 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
7275 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
7277 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
7279 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
7280 lib-prefix.m4, po.m4.
7282 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
7283 in yydestruct diagnostic, since it might not be an error.
7284 Problem reported by Joel Denny near end of
7285 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
7286 * data/lalr1.cc (yyerturn): Likewise.
7287 * data/yacc.c (yyreturn): Likewise.
7288 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
7290 * src/files.c: Remove obsolete FIXME comment.
7292 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
7293 with the other templates, and to fix bogus run-on messages such
7294 as the one reported at the end of
7295 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
7296 All callers changed to avoid the newline.
7297 (yyprocessOneStack): Output two lines rather than one, to accommodate
7298 the above change. This changes the debug output format slightly.
7300 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
7301 reported by Joel E. Denny in
7302 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
7304 * tests/glr-regression.at (Duplicate representation of merged trees):
7305 New test, from Joel E. Denny in:
7306 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
7307 * THANKS: Add Joel E. Denny.
7309 * configure.ac (AC_INIT): Bump to 2.0c.
7311 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
7313 * NEWS: Version 2.0b.
7315 * Makefile.am (SUBDIRS): Put examples before tests, so that
7316 "make check" doesn't finish with "All 1 tests passed".
7318 * tests/regression.at (Token definitions): Don't rely on
7319 AT_PARSER_CHECK for data that contains backslashes. It currently
7320 uses 'echo', and 'echo' isn't portable if its argument contains
7321 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
7322 that the byte '\0xff' is not printable in the C locale; it is,
7323 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
7324 not printable, so use '\0x81' to test.
7326 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
7327 version of GCC, since the macro is used with non-GCC compilers.
7329 Fix core dump reported by Pablo De Napoli in
7330 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
7331 * tests/regression.at (Invalid inputs with {}): New test.
7332 * src/parse-gram.y (token_name): Translate type before using
7335 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
7336 the user's name space. All uses changed to __attribute__
7338 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
7339 Add __attribute__ ((__noreturn__)).
7341 * etc/clcommit: Remove. We weren't using it, and it failed
7342 "make maintainer-distcheck".
7343 * Makefile.maint: Merge from coreutils.
7344 (CVS_LIST, CVS_LIST_EXCEPT): New macros.

7362 (signatures, %.asc): Remove.
7363 (rel-files, announcement): Remove signatures.
7364 Restore old updating code, even though we don't use it, so
7365 that we're the same as coreutils.

7367 Make the upload commands.
7369 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.

7376 * tests/sets.at: Likewise.
7378 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
7379 we comment out the Autoconf version number.
7380 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
7381 it's error-prone and "make maintainer-distcheck" rejects it.
7383 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
7384 Indent calls to "error" to pacify "make maintainer-distcheck",

7391 (sc_tight_scope): New rule, from coreutils.
7393 * src/files.c (src_extension, header_extension):
7394 Now static, not extern.
7395 * src/getargs.c (short_options): Likewise.
7396 * src/muscle_tab.c (muscle_table): Likewise.
7397 * src/parse-gram.y (current_class, current_type, current_prec):
7399 * src/reader.c (grammar_end, previous_rule_end): Likewise.
7400 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
7401 * src/main.c (main): Cast bindtextdomain and textdomain calls to
7402 void, to avoid warning when NLS is disabled.
7403 * src/output.c: Include scan-skel.h.
7404 (scan_skel): Remove decl, since scan-skel.h does this.
7406 Indent calls to "error" to pacify "make maintainer-distcheck".
7407 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
7408 * src/reader.h (gram_end, gram_lineno): New decls to pacify
7409 "make maintainer-distcheck".
7410 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
7411 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):

7416 Indent calls to "error" to pacify "make maintainer-distcheck".
7418 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
7421 * tests/torture.at: Revamp to avoid misuse of atoi that
7422 "make maintainer-distcheck" complained about.
7424 * examples/extexi (message): Don't print a message more than once,
7425 and omit line-number decoration that makes Emacs compile think
7426 that informative messages are worth worrying about.
7428 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
7430 * configure.ac: Update version number.
7432 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
7434 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
7435 autogenerated by the maintainer.
7436 * examples/calc++/.cvsignore: Add *.yy.
7438 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.

7440 * lib/bitsetv.c (bitsetv_alloc): Likewise.
7442 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
7444 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
7445 from maintainer-distcheck about casting the argument of 'free'.
7447 * NEWS: Mention recent yytname changes.
7448 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
7450 * bootstrap: For translations that have not yet been upgraded to
7451 the new runtime-po domain, prime the pump by extracting the
7452 relevant strings from the obsolete translations. This code can be
7453 removed once the bison-runtime domain has been translated by each
7456 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
7457 now that token names are already quoted.
7459 Fix problem reported by Anthony Heading.
7460 * data/glr.c (YYTOKEN_TABLE): New macro.
7461 (yytname): Define if YYTOKEN_TABLE.
7462 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
7463 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
7464 (YYERROR_VERBOSE): Define the same way the other skeletons do.

7467 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
7469 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
7470 again if the first call fails.
7472 * data/glr.c (yytnamerr): New function.
7473 (yyreportSyntaxError): Use it to dequote most string literals.
7474 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
7475 with other skeletons. All uses changed.
7476 (yytnameerr_): New function.
7477 (yyreport_syntax_error): Use it to dequote most string literals.
7478 * data/yacc.c (yytnamerr): New function.
7479 (yyerrlab): Use it to decode most string literals.
7480 * doc/bison.texinfo (Decl Summary, Calling Convention):
7481 Clarify quoting convention of yytname.
7482 * src/output.c (prepare_symbols): Quote all names. This undoes
7483 the 2005-04-17 change, which is now accomplished (mostly) via
7484 changes in the parsers as described above.
7485 * tests/regression.at (Token definitions, Web2c Actions):
7486 Undo most 2005-04-17 change here, too.
7488 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
7490 Fix more problems reported by twlevo@xs4all.nl.
7491 * tests/cxx-type.at: Don't pipe output of ./types through sed to
7492 remove trailing spaces. This loses the exit status of ./types,
7493 and isn't needed since ./types shouldn't be emitting trailing
7495 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
7496 as the stack isn't valid in that case.
7498 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
7499 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
7500 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
7501 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
7503 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
7504 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
7505 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
7508 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
7509 overly-picky compilers that reject 'char *foo = "bar";'.
7511 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
7512 to FILE * parameter, not to stderr. This fixes a typo introduced
7513 in the 2005-07-12 change.
7515 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
7516 warnings from GCC 4.
7518 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
7519 (yyglrShiftDefer, yysplitStack):
7520 Remove unused parameters b4_pure_formals. All uses changed.
7521 (yyglrShift): Remove unused parameters b4_user_formals.
7523 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
7525 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
7527 Destructor cleanups and regularization among the three skeletons.
7528 * NEWS: Document the behavior changes.
7529 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
7530 stack before failing, as the cleanup code will do it for us now.
7531 * data/lalr1.cc (yyerrlab): Likewise.
7532 * data/glr.c (yyparse): Pop everything off the stack before
7533 freeing it, so that destructors get called properly.
7534 * data/lalr1.cc (yyreturn): Likewise.
7535 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
7536 This is more consistent.
7537 * doc/bison.texinfo (Destructor Decl): Mention more reasons
7538 why destructors might be called. 1.875 -> 2.1.
7539 (Destructor Decl, Decl Summary, Table of Symbols):
7540 Some English-language cleanups for %destructor.
7541 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
7542 Add output line for destructor of start symbol.
7543 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
7544 because of that same extra output line.
7546 * NEWS: Document minor wording changes in diagnostics of
7547 Bison-generated parsers.
7548 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
7549 Remove unused formals. All uses changed.
7550 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
7551 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
7552 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
7553 Rename yyoverflowab to yyexhaustedlab.
7554 When memory exhaustion occurs during syntax-error reporting,
7555 report it separately rather than in a single diagnostic; this
7557 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
7558 (Memory Exhausted): Renamed from Parser Stack Overflow.
7559 Revamp wording slightly to prefer "memory exhaustion".
7560 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
7562 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
7564 Add i18n support to the GLR skeleton. Partially fix the C++
7565 skeleton; a C++ expert needs to finish this. Remove debugging
7566 msgids; there's little point to having them translated, since they
7567 can be understood only by someone who can read the
7568 (English-language) source code.
7570 Generate runtime-po/bison-runtime.pot automatically, so that we
7571 don't have to worry about garbage getting in that file. We'll
7572 make sure after the next official release that old msgids don't
7574 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
7576 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
7578 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
7579 Fix typos in explanations of the runtime file.
7580 * bootstrap: Change gettext keyword from YYI18N to YY_.
7581 Use standard Makefile.in.in in runtime-po, since we'll arrange
7582 for backward-compatible bison-runtime.po files in a different way.
7583 * data/glr.c (YY_): New macro, from yacc.c.
7584 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
7585 Translate messages intended for users.
7586 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
7587 the wording in the other skeletons. We don't know that the memory
7589 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
7590 Use same method that yacc.c uses.
7591 Don't translate debugging messages.
7592 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
7593 it doesn't work (yet), and requires C++ expertise to fix.
7594 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
7595 Move defn to a more logical place, to be consistent with other
7597 Don't translate debugging messages.
7598 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
7599 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
7600 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
7601 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
7603 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
7604 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
7606 * tests/glr-regression.at (Badly Collapsed GLR States):
7608 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
7609 yylex should return 0 at EOF rather than aborting.
7611 Improve tests for stack overflow in GLR parser.
7612 Problem reported by twlevo@xs4all.nl.
7613 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
7615 (yyStackOverflow): Just longjmp, but with value 2 so that caller
7616 can handle the problem.
7617 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
7618 (yyparse): New local variable yyresult to record the result.
7619 Use result of setjmp to set it, rather than storing itinto
7621 (yyDone): Remove label.
7622 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
7623 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
7624 if YYABORT is used).
7625 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
7626 yyparse status; put status > 1 into diagnostic.
7627 Check that status==2 works.
7628 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
7629 Use exit status 3 for failure to open (which shouldn't happen).
7631 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
7633 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
7634 1 on syntax error; just let yyparse do its thing.
7635 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
7636 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
7637 (Exploding the Stack Size with Alloca):
7638 (Exploding the Stack Size with Malloc):
7639 Expect exit status 2, not 1, since the parser is supposed to blow
7640 its stack. Problem reported by twlevo@xs4all.nl.
7642 * data/glr.c (yyparse): Don't assume that the initial calls
7643 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
7644 Print a stack-overflow message and fail instead.
7645 Initialize the line-number information before creating the stack,
7646 so that the stack-overflow message can report line zero safely.
7648 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
7650 Fix problems reported by twlevo@xs4all.nl.
7651 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
7652 (yyuserMerge): Provide a default case if b4_mergers is empty.
7653 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
7654 * tests/glr-regression.at
7655 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
7656 Add casts to pacify C++ compilers.
7657 * tests/glr-regression.at (Improper merging of GLR delayed action
7658 sets): Declare yylex before using it.
7659 * tests/Makefile.am (maintainer-check-g++): Fix a stray
7660 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
7661 test for valgrind; valgrind is independent of g++.
7662 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
7663 for compatibility with POSIX 1003.1-2001 (if running coreutils).
7664 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
7665 Use a destructor, so that we can expand the stack. Change
7666 YYSTYPE to char * so that we can free it. Cast result of malloc.
7668 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
7670 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
7671 a valgrind failure. Problem reported by twlevo@xs4all.nl.
7673 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
7675 * PACKAGING: New file, suggested by Bruno Haible and taken from
7676 similar wording in gettext's PACKAGING file.
7677 * NEWS: Mention PACKAGING.

7682 * NEWS: Document recent i18n improvements.
7683 * bootstrap: Get runtime translations into runtime-po.
7684 Create runtime-po files automatically, if possible.
7685 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
7686 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
7687 does not infringe on the user's name space.
7688 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
7689 * doc/bison.texinfo (Internationalization): Revamp the English
7690 and Texinfo syntax a bit, to try to make it clearer.
7691 (Bison Options, Option Cross Key): Mention --print-localedir.
7692 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
7693 YYENABLE_NLS. Quote a bit more.
7694 * runtime-po/.cvsignore: New file.

7703 * runtime-po/Makevars: Likewise.
7704 * runtime-po/LINGUAS: Likewise.
7705 * runtime-po/de.po: Likewise; we will rely on the translation project
7706 to maintain this, so "bootstrap" should get it.
7707 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
7709 * src/main.c (main): Bind the bison-runtime domain, too.
7711 2005-07-12 Bruno Haible <bruno@clisp.org>
7713 * data/yacc.c: Include <libintl.h> when NLS is enabled.
7714 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
7715 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
7716 * runtime-po: New directory.
7717 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
7718 $(DOMAIN).pot-update rule, so that old messages are never dropped.
7719 * runtime-po/Rules-quot: New file, copied from po/.
7720 * runtime-po/quot.sed: Likewise.
7721 * runtime-po/boldquot.sed: Likewise.

7743 2005-07-12 Akim Demaille <akim@epita.fr>
7745 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
7746 for consistency with the rest of the code.

7767 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
7768 and Pennello's paper.
7770 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
7772 * data/yacc.c (yyparse): Undo previous patch. Instead,
7773 set yylsp[0] and yyvsp[0] only if the initial action
7774 sets yylloc and yylval, respectively.
7776 * data/yacc.c (yyparse): In the initial action, set
7777 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
7778 This avoids the use of undefined variables if the initial
7779 action does not set yylloc and/or yylval.
7781 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7783 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
7784 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
7785 Remove from CVS. These files are automatically generated.
7786 * examples/extexi: Clarify that this file is now part of Bison,
7787 not GNU M4, and that it works with any POSIX-compatible Awk.
7788 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
7789 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
7790 so that we also get calc++-parser.yy. Geneate it.
7791 Use $(AWK), not gawk, since any conforming Awk will do.
7792 Put comment before action, since older 'make' can't handle comment
7794 $(BUILT_SOURCES): List all built sources, not just some of them.
7795 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
7796 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
7797 $($(calc_sources_generated)): Remove unnecessary test for existence
7798 of target. (This had a shell syntax error anyway; a stray "x".)
7799 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
7801 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
7803 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
7804 implied by the other modules.
7806 2005-07-06 Akim Demaille <akim@epita.fr>
7808 Bind examples/calc++ to the package.
7809 * examples/calc++/Makefile: Remove, replaced by...
7810 * examples/calc++/Makefile.am: ... this new file.
7811 * examples/calc++/test: Remove input.
7812 * examples/calc++/compile: Remove.
7813 * examples/Makefile.am: New.
7814 * configure.ac, Makefile.am: Adjust.
7815 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
7817 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
7819 * data/glr.c (yyFail): Drastically simplify; since the format argument
7820 never had any % directives, we can simply pass it to yyerror.
7821 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
7822 be modified later, as that is the usual style in glr.c.
7823 Problems reported by Paul Hilfinger.
7825 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
7826 and size overflow errors.
7827 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
7828 in case the user prolog sets feature-test macros like _GNU_SOURCE.
7829 (YYSIZEMAX): New macro.
7830 (yystpcpy): New function, taken from yacc.c.
7831 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
7832 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
7833 so that we don't have to maintain their signatures.
7834 (yyFail): Check for buffer overflow, by using vsnprintf rather
7835 than vsprintf. Allocate a bigger buffer if possible.
7836 Report an error if buffer allocation fails.
7837 (yyStackOverflow): New function.
7838 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
7839 the initialization was successful. It might fail if storage was
7841 (yyexpandGLRStack): Add more checks for storage allocation failure.
7842 Use yyStackOverflow to report failures.
7843 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
7844 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
7845 Don't assume stack number fits in int.
7846 (yysplitStack): Check for storage allocation failure.
7847 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
7848 can print diagnostics on storage allocation failure. All callers
7850 (yyresolveValue): Use yybool for boolean.
7851 (yyreportSyntaxError): Check for size-calculation overflow.
7852 This code is taken from yacc.c.
7853 (yyparse): Check for storage allocation errors when allocating
7856 2005-07-05 Akim Demaille <akim@epita.fr>
7858 Extract calc++ from the documentation.
7859 * doc/bison.texinfo (Calc++): Add the extraction marks.
7860 * examples/extexi: New, from the aborted GNU Programming 2E.
7861 Separate the different paragraph of a file with empty lines.
7862 * examples/Makefile: Use it to extract the whole calc++ example.
7864 2005-06-24 Akim Demaille <akim@epita.fr>
7866 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
7869 2005-06-22 Akim Demaille <akim@epita.fr>
7871 * doc/bison.texinfo (C++ Language Interface): First stab.
7872 (C++ Parsers): Remove.
7874 2005-06-22 Akim Demaille <akim@epita.fr>
7876 * data/lalr1.cc (yylex_): Honor %lex-param.
7878 2005-06-22 Akim Demaille <akim@epita.fr>
7880 Start a set of simple examples.

7883 * examples/calc++/calc++-parser.yy,
7884 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
7885 * examples/calc++/compile, examples/calc++/test: New.
7887 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
7889 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
7890 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
7891 which stems from the 2005-05-27 patch.
7893 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
7895 * data/glr.c: Modify treatment of unused parameters to permit use
7896 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
7898 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
7900 Fix infringement on user name space reported by Janos Zoltan Szabo.
7901 * data/yacc.c (yyparse): strlen -> yystrlen.
7903 2005-05-30 Akim Demaille <akim@epita.fr>
7905 * data/lalr1.cc (_): New.
7906 Translate the various messages.
7908 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
7910 Fix infringement on user name space reported by Bruno Haible.
7911 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
7912 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
7913 the user's name space.
7914 (alloca): Include <stdlib.h> to get it, if it's not built in.
7915 (YYMALLOC, YYFREE): Define only if needed.
7916 (malloc, free): Declare, but only if needed, as this infringes on
7917 the user name space.
7919 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
7921 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
7922 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
7924 * lib/ebitset.c (min, max): Undef before defining.
7925 * lib/vbitset.c (min, max): Likewise.
7926 * lib/subpipe.c (create_subpipe): Save local variables in case
7927 vfork clobbers them.
7929 2005-05-24 Bruno Haible <bruno@clisp.org>
7931 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
7932 error message syntax used by gcc-4.0.
7934 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
7936 * README: Mention m4 1.4.3. Remove obsolete advice about
7937 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
7939 * bootstrap: Remove workaround for problem I encountered with
7940 gettext 0.14.1; it seems to be fixed now.
7942 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
7944 * NEWS: Version 2.0a.
7946 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
7947 the previous change.
7949 Various maintainer cleanups.
7950 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
7951 conftest*, for benefit of CVS commands run at the same time as
7952 "configure". Add build-aux, since "bootstrap" now creates it and
7954 * Makefile.cfg (move_if_change): Remove.
7955 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
7956 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

7961 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
7963 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
7964 this is now the recommended name.
7965 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
7966 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
7967 ylwrap. These files now go into build-aux.
7968 * config/move-if-change: Remove.
7969 * config/prev-version.txt: Bump from 1.75 to 2.0.
7971 * bootstrap: Add stdio-safer, unistd-safer modules.
7972 Remove m4/glibc2.m4 (introduced by latest gnulib, but
7974 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
7975 fopen-safer.c, stdio-safer.h, unistd-safer.h.
7976 * lib/subpipe.c: Include "unistd-safer.h".
7977 (create_subpipe): Make sure all the newly-created
7978 file descriptors are > 2, so that diagnostics don't
7979 get sent down them (which might cause Bison to hang, in theory).
7980 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
7981 * src/files.c (xfopen): Use fopen_safer, not fopen.
7983 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
7984 yesterday's yacc.c fix.
7986 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>

7990 Fix a destructor bug reported by Wolfgang Spraul in
7991 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
7992 * data/yacc.c (yyabortlab): Don't call destructor, and
7993 don't set yychar to EMPTY.
7994 (yyoverflowlab): Don't call destructor.
7995 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
7996 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
7997 since we no longer output the message "discarding lookahead token
8000 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8002 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
8003 fix a small glitch in debugging output.
8004 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
8005 after YY_SYMBOL_PRINT where needed.
8007 (struct yyGLRState): Add some comments.
8008 (struct yySemanticOption): Add some comments.
8009 (union yyGLRStackItem): Add comment.
8011 (yymergeOptionSets): Correct this to properly perform the union,
8012 avoiding infinite reported by Michael Rosien.

8056 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
8058 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
8059 Problem reported by Ralf Menzel.
8061 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8063 * tests/actions.at: Test that stack overflow invokes destructors.
8064 From Marcus Holland-Moritz.
8065 * data/yacc.c (yyerrlab): Move the code that destroys the stack
8067 (yyreturn): to here. That way, destructors are called properly
8068 even if the stack overflows, or the user calls YYACCEPT or
8069 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
8070 (yyoverflowlab): Destroy the lookahead.
8072 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
8074 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
8076 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
8078 * NEWS: Bison-generated C parsers no longer quote literal strings
8079 associated with tokens.
8080 * src/output.c (prepare_symbols): Don't escape strings,
8081 since users don't want to see C escapes.
8082 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
8084 * tests/input.at (Torturing the Scanner): Likewise.
8085 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
8087 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
8089 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
8090 the data size is known to be too small and we can't increase it.
8091 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
8093 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
8095 * src/parse-gram.y: Include quotearg.h.
8096 (string_as_id): Quote $1 before using it as a key, since the
8097 lexer no longer quotes it for us.
8098 (string_content): Don't strip quotes, since lexer no longer
8100 * src/scan-gram.l: Include quotearg.h.
8102 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
8103 a key, since the rest of the lexer doesn't quote it.
8104 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
8105 * tests/regression.at (Token definitions): Check for backslashes
8108 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
8109 (YYSIZE_T): Define to unsigned long int when using an older compiler.
8110 (yyparse): Revamp code to generate long syntax error message, to
8111 make it easier to translate, and to avoid problems with arithmetic
8112 overflow. Change "virtual memory" to "memory" in diagnostic, since
8113 we don't know whether the memory is virtual.
8115 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8117 * NEWS: Bison-generated C parsers now use the _ macro to
8119 * data/yacc.c (_) [!defined _]: New macro.
8120 All English strings wrapped inside this macro.
8121 * doc/bison.texinfo (Bison Parser): Document _.
8122 * po/POTFILES.in: Include src/parse-gram.c, since it now
8123 includes translateable strings that parse-gram.y doesn't.
8125 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
8127 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
8128 reverting the 2004-10-11 change to this function.
8129 (symbol_check_alias_consistency): Don't call symbol_type_set
8130 if the type name is already correct.
8131 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
8133 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
8135 * tests/regression.at (Token definitions): Don't use a token named
8136 c, as that generates a "#define c ..." that runs afoul of buggy
8137 stdlib.h that uses the identifier c as a member of struct
8138 drand48_data. Problem reported by Horst Wente.
8140 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
8142 * bootstrap: Change translation URL from
8143 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
8144 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
8145 redirection glitches. Problem reported by twlevo@xs4all.nl.
8147 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
8149 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
8150 after operands; POSIX says this isn't portable for the c99 command.
8152 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
8154 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
8155 immediately if a data overrun has occurred; this may help us track
8156 down what may be a spurious failure on MacOS.
8158 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
8160 Respond to problems reported by twlevo@xs4all.nl.
8162 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
8164 * src/vcg.h: Comment fix.
8165 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
8166 (G_CMAX): Change to -1 instead of INT_MAX.
8168 * data/yacc.c (yyparse): Omit spaces before #line.
8170 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
8172 * src/tables.c (state_number_to_vector_number): Put it inside an
8173 "#if 0", since it's not currently used. Problem reported by
8176 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
8178 * src/output.c (escaped_output): Renamed from
8179 escaped_file_name_output, since we now use it for symbol tags as
8180 well. All uses changed.
8181 (symbol_destructors_output, symbol_printers_output):
8182 Escape symbol tags too.
8183 Problem reported by Matyas Forstner in
8184 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
8186 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
8188 * src/output.c (user_actions_output, token_definitions_output,
8189 symbol_destructors_output, symbol_printers_output): Likewise.
8190 * src/reader.c (prologue_augment): Likewise.
8191 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
8193 * src/vcg.c (output_edge): Don't quote linestyle arg.
8194 Problem reported by twlevo@xs4all.nl.
8196 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
8198 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
8199 example, reported by Derek M Jones. Also, make the example even
8200 more outrageous, to better illustrate how bad the problem is.
8202 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
8204 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
8205 putsym. Typo reported by Sebastian Piping.
8207 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8209 * doc/bison.texinfo (Language and Grammar): some -> same
8210 (Epilogue): int he -> in the
8211 Typos reported by Sebastian Piping via Justin Pence.
8213 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8215 * tests/glr-regression.at (Improper handling of embedded actions
8216 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
8217 embedded actions and $-N in GLR parsers", work around an Autoconf bug
8218 with dollar signs in test names.
8219 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
8220 for a similar reason.
8222 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8224 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
8225 wants to redefine G_VIEW.
8227 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
8229 * src/vcg.c (get_view_str): Remove case for normal_view.
8230 Problem reported by twlevo@xs4all.nl.
8232 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
8234 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
8235 Problem reported by twlevo@xs4all.nl.
8237 * doc/bison.texinfo: Change @dircategory from "GNU programming
8238 tools" to "Software development". Requested by Richard Stallman
8241 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
8243 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
8244 Problem reported by twlevo@xs4all.nl.
8246 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
8248 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
8249 keyword; it's not needed with modern compilers, and it doesn't
8250 affect correctness with older compilers. Suggested by
8253 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
8255 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
8256 gcc -Wswitch-default.
8257 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
8258 * data/yacc.c (yyparse): Likewise.
8260 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
8262 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
8263 already. Let config.h define any nonstandard values.
8265 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
8267 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
8268 for the benefit of slower hosts. Problem reported by
8271 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
8273 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
8274 being defined and not used.
8275 * data/lalr1.cc (yyparse): Likewise.
8276 Use "if (false)" rather than "if (0)".
8278 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
8280 * TODO: Mention that we should allow NUL bytes in tokens.
8282 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
8284 * src/scan-skel.l (<<EOF>>): Don't close standard output.
8285 Problem reported by Hans Aberg.
8287 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
8289 * src/getargs.c (version): Happy new year; update overall
8290 program copyright date from 2004 to 2005.
8292 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
8293 Problem reported by Hans Aberg.
8294 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
8295 (Output file names.): Add a test for the case when standard output
8298 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
8300 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
8301 to fix an oversight in the Bison 2.0 manual.
8303 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
8305 * NEWS: Version 2.0. Reformat the existing news items since
8306 1.875, so that related items are grouped together.
8307 * configure.ac (AC_INIT): Bump version to 2.0.
8308 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
8310 * tests/torture.at (Exploding the Stack Size with Alloca): Set
8311 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
8312 otherwise, we're not testing alloca. Unfortunately there's no
8313 simple way to consult HAVE_ALLOCA here.
8315 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
8318 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
8319 hand. This avoids a warning about comparing int to size_t when
8320 GCC warnings are enabled.
8322 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
8324 * NEWS: Bison-generated parsers no longer default to using the
8325 alloca function (when available) to extend the parser stack, due
8326 to widespread problems in unchecked stack-overflow detection.
8327 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
8328 responsibility to set it to a positive value. This lets the user
8329 specify a value that is not a preprocessor constant.
8330 * data/yacc.c (YYMAXDEPTH): Likewise.
8331 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
8332 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
8333 to be a compile-time constant. However, explain the constraints on it.
8334 Also, explain the constraints on YYINITDEPTH.
8335 (Table of Symbols): Explain that alloca is no longer the default.
8336 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
8339 * doc/bison.texinfo (Location Default Action): Mention that n must
8340 be zero when k is zero. Suggested by Frank Heckenbach.
8342 2004-12-22 Akim Demaille <akim@epita.fr>
8344 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
8345 (parser::state_type, parser::semantic_type, parser::location_type):
8346 Private, not public.
8347 (parser::parse): Return ints, not bool.
8348 Returning a bool introduces a problem: 0 corresponds to false, and
8349 it seems weird to return false on success. Returning true changes
8350 the conventions for yyparse.
8351 Alternatively we could return void and send an exception.
8352 There is no clear consensus (yet?).
8353 (state_stack, semantic_stack, location_stack): Rename as...
8354 (state_stack_type, semantic_stack_type, location_stack_type): these.
8355 Private, not public.
8356 * tests/c++.at: New.
8357 * tests/testsuite.at, tests/Makefile.am: Adjust.
8359 2004-12-21 Akim Demaille <akim@epita.fr>
8361 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
8363 2004-12-21 Akim Demaille <akim@epita.fr>
8365 Don't impose std::string for filenames.
8367 * data/lalr1.cc (b4_filename_type): New.
8368 (position::filename): Use it.
8369 (parser.hh): Move the inclusion of stack.hh and location.hh below
8370 the user code, so that needed headers for the filename type can be
8372 Forward declare them before the user code.
8373 * tests/Makefile.am (check-local, installcheck-local): Pass
8374 TESTSUITEFLAGS to the TESTSUITE.
8376 2004-12-20 Akim Demaille <akim@epita.fr>
8378 Use more STL like names: my_class instead of MyClass.
8380 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
8381 (SemanticStack, SemanticType, StateStack, StateType)
8382 (TokenNumberType, Stack, Slice, Traits, Parser::location)
8383 (Parser::value): Rename as...
8384 (location_stack, location_type, rhs_number_type, semantic_stack)
8385 (semantic_type, state_stack, state_type, token_number_type, stack)
8386 (slice, traits, parser::yylloc, parser::yylval): these.
8388 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
8390 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
8392 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
8393 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
8395 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
8397 Remove uses of 'short int' and 'unsigned short int'. This raises
8398 some arbitrary limits. It uses more memory but nowadays that's
8399 not much of an issue.
8401 This change does not affect the generated parsers; that's a different
8402 task, as some users will want to conserve memory there.
8404 Ideally we should use size_t to represent all object counts, and
8405 something like ptrdiff_t to represent signed differences of object
8406 counts; but that will require more code-cleanup than I have the
8407 time to do right now.
8409 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
8410 Use size_t, not int or short int, to count objects.
8411 * src/closure.c (nritemset, closure): Likewise.
8412 * src/closure.h (nritemset, closure): Likewise.
8413 * src/nullable.c (nullable_compute): Likewise.
8414 * src/print.c (print_core): Likewise.
8415 * src/print_graph.c (print_core): Likewise.
8416 * src/state.c (state_compare, state_hash): Likewise.
8417 * src/state.h (struct state): Likewise.
8418 * src/tables.c (default_goto, goto_actions): Likewise.
8420 * src/gram.h (rule_number, rule): Use int, not short int.
8421 * src/output.c (prepare_rules): Likewise.
8422 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
8423 errs, reductions): Likewise.
8424 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
8426 * src/tables.c (vector_number, tally, action_number,
8427 ACTION_NUMBER_MINIMUM): Likewise.
8428 * src/output.c (muscle_insert_short_int_table): Remove.
8430 2004-12-17 Akim Demaille <akim@epita.fr>
8432 * data/lalr1.cc: Extensive Doxygenation.
8433 (error_): Rename as...
8434 (error): this, since it is visible to the user.
8436 (Parser::message): Now an automatic variable from...
8437 (Parser::yyreport_syntax_error_): here.
8438 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
8440 * tests/input.at: Escape $.
8442 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
8444 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
8445 Parenthesize rhs to avoid obscure problems with mistakes like
8446 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
8447 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
8448 b4_rhs_location): Likewise.
8449 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
8450 b4_rhs_location): Likewise.
8452 2004-12-16 Akim Demaille <akim@epita.fr>
8454 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
8455 yacc.c: be sure to stay within yycheck_.
8456 * tests/actions.at: Re-enable C++ tests.
8458 2004-12-16 Akim Demaille <akim@epita.fr>
8460 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
8463 2004-12-16 Akim Demaille <akim@epita.fr>
8465 Use #define to handle the %name-prefix.
8467 * data/glr.c, data/yacc.c: Comment changes.
8468 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
8469 so that one can refer to yylex in the parser file, and have it
8470 renamed, as is the case with other skeletons.
8472 2004-12-16 Akim Demaille <akim@epita.fr>
8474 Move lalr1.cc internals into yy*.

8494 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
8496 Fix some problems reported by twlevo at xs4all.
8497 * src/symtab.c (symbol_new): Report an error if the input grammar
8498 contains too many symbols. This is better than calling abort() later.
8499 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
8500 (struct node, struct graph):
8501 Rename member expand to stretch. All uses changed.
8502 (struct graph): Remove member layoutalgorithm. All uses removed.
8503 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
8504 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.

8508 2004-12-15 Akim Demaille <akim@epita.fr>
8510 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
8511 Add more Doxygen comments.
8512 (symprint_, stack_print_, reduce_print_, destruct_, pop)
8513 (report_syntax_error_, translate_): Rename as...
8514 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
8515 (yypop_, yyreport_syntax_error_, yytranslate_): this.
8517 2004-12-15 Akim Demaille <akim@epita.fr>
8519 * data/lalr1.cc (lex_): Rename as...
8521 Move the trace here.
8522 Take the %name-prefix into account.
8523 Reported by Alexandre Duret-Lutz.
8525 2004-12-15 Akim Demaille <akim@epita.fr>
8527 Simplify the C++ parser constructor.
8529 * data/lalr1.cc (debug_): Rename as...
8530 (yydebug_): so that the parser's internals are always in the yy*
8533 (b4_parse_param_decl): Remove the leading comma as it is now only
8534 called as unique argument list.
8535 (Parser::Parser): Remove the constructor accepting a location and
8536 an initial debugging level.
8537 Remove from the other ctor the argument for the debugging level.
8538 (debug_level_type, debug_level, set_debug_level): New.
8540 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
8543 2004-12-15 Akim Demaille <akim@epita.fr>
8545 Remove b4_root related material: failure experiment
8546 (which goal was to allow to derive from a class).
8548 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
8549 definitions and uses.
8551 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
8553 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
8554 not 2, since it's not portable to subtract 1 from the start of an
8555 array. The new item 0 is never set or used. All uses changed.
8557 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
8558 the default definition of YYLLOC_DEFAULT. Problem reported
8559 by Frank Heckenbach.
8561 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
8563 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
8564 the normal case and one for the error case. Just use the
8565 first one uniformly. Problem reported by Frank Heckenbach.
8566 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
8567 use exactly the same macro in both places.
8568 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
8569 so that the normal-case YYRHSLOC works for the error case too.
8571 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
8572 (YYLLOC_DEFAULT): Use the same macro as glr.c.
8573 * doc/bison.texinfo (Location Default Action): Don't claim that
8574 we have an array of locations. Use the same macro for both glr
8575 and lalr parsers. Mention YYRHSLOC. Mention what happens when
8578 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
8580 * HACKING: Update email addresses to send announcements to.
8582 * configure.ac (AC_INIT): Bump version to 1.875f.
8584 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
8586 * NEWS: Version 1.875e.
8587 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
8589 * src/scan-skel.l: Include "complain.h", for "fatal".
8591 * src/relation.h (relation_print, relation_digraph):
8592 Relation sizes are of type relation_node, not size_t (this is
8593 merely a doc fix, since the two types are equivalent).
8594 (relation_transpose): Relation sizes are of type relation_node,
8596 * src/relation.c: Likewise.
8597 (top, infinity): Now of type relation_node, not int.
8598 (traverse, relation_transpose): Use relation_node, not int.
8600 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
8601 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
8602 (yyparse): Remove unused local introduced in 2004-10-25 patch.
8604 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
8605 specifying whether the test should be skipped. Use it tp
8606 specify that the [%defines %skeleton "lalr1.cc"] tests currently
8607 fail on some hosts, and should be skipped.
8609 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
8611 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
8612 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
8613 unless otherwise specified below.
8615 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
8616 to allocate kernel_base, kernel_items, kernel_size, since
8617 they needn't be initialized to 0.
8618 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
8619 * src/closure.c (new_closure): Likewise, for itemset.
8620 * src/derives.c (derives_compute): Likewise, for delts, derives, q.

8632 (token_actions): Likewise for yydefact, actrow, conflrow,
8634 (save_column): Likewise for froms[symno], tos[symno].
8635 (goto_actions): Likewise for state_count.
8636 (pack_table): Likewise for base, pos, check.
8637 (tables_generate): Likewise for width.
8639 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
8640 for initial core. Just have a separate core, so we needn't worry
8641 about whether kernel_size and kernel_base are initialized.
8643 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
8644 kernel_size, kernel_items): Remove unnecessary initialization.
8645 * src/conflicts.c (conflicts): Likewise.

8649 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
8650 conflrow, conflict_table, conflict_list, table, check):
8653 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
8654 This is because all callers pass unsigned int.
8655 * src/closure.h (new_closure): Likewise.
8657 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
8658 (build_relations): Initialize includes[i] in all cases.
8659 * src/reader.c (packgram): Always initialize rules[ruleno].prec
8660 and rules[ruleno].precsym. Initialize members in order.
8661 * src/relation.c (relation_transpose): Always initialize new_R[i]
8663 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
8665 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
8666 conflict_list[0] was always 0, but now it isn't initialized.
8668 * src/table.c (table_grow): When conflict_table grew, the grown
8669 area wasn't cleared. Fix this.
8671 * lib/.cvsignore: Add strdup.c, strdup.h.
8672 * m4/.cvsignore: Add strdup.m4.
8674 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
8676 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
8677 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
8678 GOTO_NUMBER_MAXIMUM, since we occasionally compute
8679 ngotos + 1 without checking for overflow.
8680 (build_relations): Use END_NODE, not -1, to denote end of edges.
8681 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
8682 build_relations): Use goto_number, not int, for goto numbers.
8683 * src/tables.c (save_column, default_goto): Likewise.
8685 2004-11-23 Akim Demaille <akim@epita.fr>
8687 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
8688 of #defining from yystype.
8689 Don't typedef yystype, C++ does not need it.
8690 This lets it possible to forward declare it as union.
8692 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
8694 * bootstrap (gnulib_modules): Add extensions.
8695 Problem reported by Jim Meyering.
8697 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>

8701 src/system.h, src/tables.c: XFREE -> free, to accommodate
8702 recent change to gnulib xalloc.h.
8703 Problem reported by Jim Meyering.
8705 2004-11-17 Akim Demaille <akim@epita.fr>
8707 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
8709 2004-11-17 Akim Demaille <akim@epita.fr>,
8710 Alexandre Duret-Lutz <adl@gnu.org>
8712 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
8715 Use it instead of cdebug_.
8716 (Parser::debug_stream, Parser::set_debug_stream): New.
8717 (Parser::symprint_): Define cdebug_ for temporary backward

8722 2004-11-17 Akim Demaille <akim@epita.fr>
8724 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
8725 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
8726 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
8727 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
8729 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
8731 * data/glr.c (yyloc_default): Remove; not used.
8732 Problem reported by Frank Heckenbach.
8734 2004-10-25 Akim Demaille <akim@epita.fr>
8736 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
8737 Introduce another definition to address simple location arrays.
8738 (yyGLRStack): New member: yyerror_range.
8739 (yyrecoverSyntaxError, yyparse): Update it.
8740 (yyrecoverSyntaxError): Use it when shifting the error token to
8741 have an accurate range, equivalent to the one computed by both
8742 yacc.c and lalr1.cc.
8743 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
8744 that column numbers start at column 0, as per GNU Coding
8745 Standards, the others tests, and the doc.
8746 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
8747 Adjust to the above change (first column is 0).
8748 And adjust the location of the "<error>", now covering the whole
8751 2004-10-22 Akim Demaille <akim@epita.fr>
8752 and Paul Eggert <eggert@cs.ucla.edu>
8754 Remove some arbitrary limits on goto numbers and relations.
8755 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
8756 initial values, since they're never used.
8757 (set_goto_map): ngotos is now unsigned, so test for overflow
8758 by seeing whether it wraps around to zero.
8759 * src/lalr.h (goto_number): Now size_t, not short int.
8760 (GOTO_NUMBER_MAXIMUM): Remove.
8761 * src/relation.c (relation_print, traverse, relation_transpose):
8762 Check for END_NODE rather than looking at sign.
8763 * src/relation.h (END_NODE): New macro.
8764 (relation_node): Now size_t, not short int.
8766 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
8768 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
8769 keyword, not an identifier. Problem reported by Baron Schwartz in
8770 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
8772 2004-10-11 Akim Demaille <akim@epita.fr>
8774 * src/symtab.c (symbol_check_alias_consistency): Also check
8775 type names, destructors, and printers.
8776 Reported by Alexandre Duret-Lutz.
8777 Recode the handling of associativity and precedence in terms
8778 of symbol_precedence_set.
8779 Accept no redeclaration at all, not even equal to the previous
8781 (redeclaration): New.
8782 Use it to factor redeclaration complaints.
8783 (symbol_make_alias): Don't set the type of the alias, let
8784 symbol_check_alias_consistency do it as for other features.
8785 * src/symtab.h (symbol): Add new member prec_location, and
8787 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
8788 * tests/input.at (Incompatible Aliases): New.
8790 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
8792 .cvsignore fixes to accommodate gnulib changes,
8793 and the practice of naming build directories "_build".
8794 * .cvsignore: Add "_*". Sort.
8795 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
8796 * m4/.cvsignore: Add "*_gl.m4".
8798 2004-10-06 Akim Demaille <akim@epita.fr>
8800 * src/parse-gram.y (add_param): Fix the truncation of trailing
8803 2004-10-05 Akim Demaille <akim@epita.fr>
8805 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
8806 whether the reducion was empty or not. This leaves room to
8807 improve the use of YYLLOC_DEFAULT in such a case.
8808 lalr1.cc is still experimental, so changing this is acceptable.
8809 And finally, there are probably not many users who changed the
8810 handling of locations in GLR, so changing is admissible too.
8812 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
8813 empty reduction, set @$ to an empty location ending the previously
8815 Adjust uses to make sure the code is triggered on empty
8817 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
8818 expected output: empty reductions have empty locations.
8820 2004-09-29 Akim Demaille <akim@epita.fr>
8822 * data/lalr1.cc: Move towards a more standard C++ coding style
8823 for templates: Class < T > -> Class<T>.
8825 2004-09-29 Akim Demaille <akim@epita.fr>
8827 * data/lalr1.cc: Reinstall the former ctor, for sake of
8828 compatibility, but warn it will be removed.
8829 Move towards a more standard C++ coding style (i.e., type *var ->
8832 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
8834 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
8835 since it's less likely to work if NULs are involved in the future.
8837 2004-09-27 Akim Demaille <akim@epita.fr>
8839 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
8841 2004-09-27 Akim Demaille <akim@epita.fr>
8843 * data/lalr1.cc (b4_parse_param_decl_1): New.
8844 (b4_parse_param_decl): Use it to have different names between attribute

8848 2004-09-24 Akim Demaille <akim@epita.fr>
8850 * src/parse-gram.y (add_param): Strip the leading and trailing
8851 blanks from a formal argument declaration.
8852 (YY_LOCATION_PRINT): New.
8854 2004-09-24 Akim Demaille <akim@epita.fr>

8865 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
8866 the useless parentheses.
8867 Suggested by Paul Eggert.
8869 2004-09-20 Akim Demaille <akim@epita.fr>
8871 Let the initial-action act on the look-ahead, and use it for the
8872 "initial push" (corresponding to an hypothetical beginning-of-file).
8873 And let lalr1.cc honor %initial-action.
8875 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
8877 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
8878 (Parser::Parser): Remove the ctor that used to initialize it.
8879 (Parser::parse): Like in the other skeletons, issue the "starting
8880 parse" message before any action.
8881 Honor %initial-action.
8882 Initialize the stacks with the lookahead.
8883 * data/yacc.c: Let $$ and @$ in %initial-action designate the
8885 Push them in the stacks.
8886 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
8888 2004-09-20 Akim Demaille <akim@epita.fr>
8890 * doc/bison.texinfo (Initial Action Decl): New.
8892 2004-09-20 Akim Demaille <akim@epita.fr>
8894 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
8895 clearer criterion to define it.
8896 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
8897 When reducing on an empty RHS, use the latest stacked location as
8899 yylloc is not always available.
8900 * data/glr.c: Likewise.
8901 Also, honor initial-actions.
8903 2004-09-20 Akim Demaille <akim@epita.fr>
8905 * data/yacc.c (YY_LOCATION_PRINT): New.
8906 Define when we know YYLTYPE's structure, i.e., when the default
8907 YYLLOC_DEFAULT is used.
8908 * data/c.m4 (b4_yysymprint_generate): Use it.
8909 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
8910 value of the result.
8911 (error_start_): Replace with...
8912 (error_range_): this location array.
8913 This allows to replace code relying on the implementation of
8914 locations by portable code.
8915 * data/yacc.c (yylerrsp): Replace with...
8916 (yyerror_range): this.
8917 Every time a token is popped, update yyerror_range[0], to have an
8918 accurate location for the error token.
8919 * data/glr.c (YY_LOCATION_PRINT): New.
8920 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
8921 deference a pointer.
8922 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
8923 report the location in %printers.
8925 * src/scan-skel.l: Instead of abort, report error messages to ease
8926 understanding skeleton scanning failures.
8928 2004-09-16 Akim Demaille <akim@epita.fr>
8930 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
8931 (iterator, const_iterator): these, to be more in the C++ spirit.
8932 Also, return reverse iterators so that when displaying the stack
8933 we display its bottom first.
8934 (Parser::stack_print_, Parser::reduce_print_): Match the messages
8936 We should probably use vector here though.
8938 2004-09-16 Akim Demaille <akim@epita.fr>
8940 Have more complete shift traces.
8942 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
8943 to report Shifts instead of ad hoc YYDPRINTF invocations,
8944 including for the error token.
8945 * data/lalr1.cc (symprint_): Output the location.
8946 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
8947 output the location within the %printer.
8948 Activate GLR tests, at least to make sure they compile properly.
8949 They still don't pass though.
8950 * tests/calc.at: Adjust expect verbose output, since now "Entering
8951 state..." is on a different line than the "Shifting" message.
8953 2004-09-08 Akim Demaille <akim@epita.fr>
8955 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
8956 Bison directive from the Bison file to the invocation of this
8957 macro, so that these directives are passed to
8958 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
8959 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
8960 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
8961 the extra Bison directives instead of the whole series.
8962 Change the grammar so that there are recoverable errors, and
8963 unrecoverable errors. Now we can have the parser give up before
8964 consuming the whole input. As a result we now can observe that
8965 the lookahead is freed when needed.
8966 Change the parser source to parse argv[1] instead of a hard coded
8968 Simplify yylex, and give a value and location to EOF.
8969 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
8970 passed directives already coded in the file.
8971 Add some tests to check the location of "error".
8972 For some tests, the C++ parser is correct, and not yacc.c.
8973 For other tests, they provide different, but unsatisfying, values,
8974 so keep the C++ value so that at least one parser is "correct"
8975 according to the test suite.
8976 (Actions after errors): Remove, this is subsumed by the
8977 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
8979 2004-09-06 Akim Demaille <akim@epita.fr>
8981 * data/lalr1.cc: Adjust the indentation of the labels.
8985 2004-09-06 Akim Demaille <akim@epita.fr>
8987 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
8988 argument, an informative message.
8989 Call YY_SYMBOL_PRINT.
8990 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
8991 * data/lalr1.cc (destruct_): Likewise.
8992 In addition, no longer depend on b4_yysymprint_generate and
8993 b4_yydestruct_generate to generate these functions, do it "by
8996 2004-09-03 Akim Demaille <akim@epita.fr>
8998 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
8999 invoked, yydestruct the lookahead.
9000 * tests/calc.at (Calculator $1): Update the expected lengths of
9001 traces: there is an added line for the discarded lookahead.
9002 * doc/bison.texinfo (Destructor Decl): Some rewording.
9003 Define "discarded" symbols.
9005 2004-09-02 Akim Demaille <akim@epita.fr>
9007 * data/lalr1.cc (translate_, destruct_): No reason to be static.
9009 2004-09-02 Akim Demaille <akim@epita.fr>
9011 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
9012 (YYDSYMPRINTF): Rename as...
9013 (YY_SYMBOL_PRINT): this.
9014 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
9016 Use it instead of direct symprint_ calls.
9017 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
9020 2004-09-02 Akim Demaille <akim@epita.fr>
9022 * data/lalr1.cc (b4_yysymprint_generate): New.
9023 (symprint_): New member function, defined when YYDEBUG.
9024 Use it consistently instead of token/nterm debugging output by
9026 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
9027 %printer calls to use cdebug_ when using lalr1.cc.
9029 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
9031 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
9032 with #ifdef YYDEBUG.
9034 2004-08-26 Akim Demaille <akim@epita.fr>
9036 * doc/bison.texinfo (Implementing Loops): Rename as...
9037 (Implementing Gotos/Loops): this.
9039 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
9041 Adjust to latest gnulib.
9042 * bootstrap (gnulib_modules): Add xalloc-die.
9043 Set LC_ALL=C so that file names sort consistently.
9044 Prefer the gnulib copies of gettext.m4, glibc21.m4,
9045 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
9046 uintmax_t.m4, ulonglong.m4.
9047 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
9048 po.m4 since we are now using _gl.m4 instead.
9050 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
9052 * src/scan-action.l: Remove. Scanning of semantic actions is
9053 handled in scan-gram.l.
9055 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
9057 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
9059 * src/location.h (struct): The file member is a uniqstr.
9060 (equal_boundaries): Use UNIQSTR_EQ for comparison.
9062 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
9064 Fix bug with non-%union parsers that have printers or destructors,
9065 which led to a Bison core dump. Reported by Peter Fales in
9066 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
9068 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
9069 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
9070 not to our own type.
9071 * src/output.c (symbol_destructors_output, symbol_printers_output):
9072 Don't assume %union.
9073 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
9074 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
9075 UNION-FLAG. All callers changed.
9076 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
9077 Use type char, not unsigned int, when declaring an array of char;
9078 this lets us remove a cast.
9079 (Printers and Destructors): Add non-%union test cases.
9081 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
9083 * doc/bison.texinfo: Minor editorial changes, mostly to the new
9084 GLR writeups. E.g., avoid frenchspacing and the future tense,
9085 change "lookahead" to "look-ahead", and change "wrt" to "with
9088 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9090 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
9091 New sections, split off from the GLR Parsers section. Put the new
9092 Simple GLR Parser near the start of the GLR section, for clarity.
9093 Rewrite connective text.
9095 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
9097 * doc/bison.texinfo (Simple GLR Parsers): New section.
9099 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
9101 * NEWS, TODO, doc/bison.texinfo:
9102 Use "look-ahead" instead of "lookahead", to be consistent.
9103 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
9104 while we're fixing "look-ahead".
9105 * src/conflicts.c (shift_set): Renamed from shiftset.
9106 (look_ahead_set): Renamed from lookaheadset.
9107 * src/print.c: Likewise.

9122 AT_DATA_LOOKAHEADS_GRAMMAR.
9124 2004-06-03 Paul Eggert <eggert@cs.ucla.edu>
9126 * README: Update location of patched M4 distribution.
9128 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
9130 Don't assume the C++ compiler takes the same arguments as the C compiler
9132 * configure.ac (O0CXXFLAGS): New var.
9133 * tests/atlocal.in (CXXFLAGS): Use it.
9135 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
9137 Fix some "make check" problems with C++ reported by
9138 Albert Chin-A-Young for Tru64 C++ in this thread:
9139 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
9141 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
9142 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
9143 Output to a .cc file for C++, not to a .c file.

9145 * tests/regression.at (AT_CHECK_DANCER): Likewise.
9146 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
9148 2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
9150 * tests/calc.at, tests/actions.at: Workaround for SGI
9151 C++ compiler. (trivial change)
9153 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
9155 Spent a few hours checking out which prerequisite versions the
9156 current sources actually require. I went all the way back to
9157 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
9158 a seemingly endless set of combinations of versions more recent
9159 than that. The bottom line is that the current sources require
9160 fairly recent versions of the build tools, and it'll be some work
9162 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
9163 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
9164 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
9165 Add comments explaining why those particular versions are
9168 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
9169 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
9170 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
9172 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
9173 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
9175 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9177 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
9178 0.11.5. Suggested by Bruno Haible.
9179 * bootstrap: Remove gettext version checking.
9181 * doc/bison.texinfo (Decl Summary): Also mention that %union
9182 can depend on prerequisite types. Problem reported by Tim

9200 Undo change made earlier today: it caused autopoint to not bring
9201 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
9204 * bootstrap: Check that gettext version matches what's in
9205 configure.ac. Warn users to ignore robots.txt ERROR 404.
9206 * bootstrap: Undo today's earlier change (logged below).
9207 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
9209 The gettext version checking is causing more trouble than it's
9210 curing; remove it. Problem reported by Paul Hilfinger.
9212 * bootstrap: Issue a warning that one can expect a message
9213 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
9214 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
9216 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>

9246 supported by GCC 3.4.0.
9247 * README: Mention GNU m4 1.4 or later; mention m4 patches.

9286 * src/.cvsignore: Add *.output.
9288 * src/parse-gram.y: Put copyright notice inside %{ %} so it
9289 gets copied to the output file.
9291 2004-04-28 Paul Eggert <eggert@twinsun.com>
9293 Get files from the gnulib and po repositories, instead of relying
9294 on them being in our CVS. Upgrade to latest versions of gnulib
9297 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
9298 * bootstrap: Bootstrap from gnulib and po repositories.
9299 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
9300 * README-cvs: Document these changes. Remove version numbers from

9306 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
9308 (AC_ISC_POSIX): Remove; we no longer support this
9309 ancient OS, as it gets in the way of latest Autoconf & gnulib.

9327 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
9328 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):

9423 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
9424 so that this include file can stand alone.
9425 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
9426 does this now. Include subpipe.h first after config.h, to
9427 test whether it can stand alone.
9429 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
9430 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the

9434 the union, because empty unions aren't allowed in C. Caught
9437 2004-04-13 Jim Meyering <jim@meyering.net>
9439 * src/conflicts.c (conflicts_print): Correct format string typo:

9541 token so that it covers all the discarded tokens.
9542 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
9543 it can be called with `%skeleton "lalr1.cc"', and do that.
9545 2004-02-02 Paul Eggert <eggert@twinsun.com>
9547 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
9548 $(top_srcdir)/lib and ../lib. This fixes a bug reported
9549 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
9550 There's no need to mention top_builddir since Automake does that
9552 (INCLUDES): Remove, as Automake says it's obsolescent.
9553 Contents migrated into AM_CPPFLAGS as described above.

9565 resulting parsers are compilable with C++.
9567 2003-12-23 Paul Eggert <eggert@twinsun.com>
9569 * config/depcomp, config/install-sh: Sync with Automake 1.8.
9570 * src/output.c (output_skeleton): Rename local var.
9571 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
9572 Bison tokens, as this runs afoul of the 2003-10-07 change that
9573 disallowed NUL bytes in character constants or string literals.
9575 * tests/local.at: Require Autoconf 2.59's Autotest.
9576 * tests/testsuite.at: Don't include local.at, since we now assume
9577 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
9579 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
9580 multiple inclusion warnings.
9582 2003-12-02 Akim Demaille <akim@epita.fr>

9595 if testsuite doesn't exist.

9598 literals, unfortunately.
9599 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
9600 Complain about NUL bytes in character constants or string literals.
9602 2003-10-05 Paul Eggert <eggert@twinsun.com>
9604 * NEWS: Don't document %no-default-prec, as it's still
9606 * doc/bison.texinfo: Document %no-default-prec only if
9607 the defaultprec flag is set. Normally it's not.
9609 2003-10-04 Paul Eggert <eggert@twinsun.com>
9611 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
9612 non-modifiable lvalue, instead of a modifiable one.
9613 * doc/bison.texinfo (Actions): Document that $$ can

9675 2003-08-25 Akim Demaille <akim@epita.fr>
9677 When reducing initial empty rules, Bison parser read an initial
9678 location that is not defined. This results in garbage, and that
9679 affects Bison's own parser. Therefore we need (i) to extend Bison
9680 to support a means to initialize this location, and (ii) to use
9681 this CVS Bison to fix CVS Bison's parser.
9683 * src/reader.h, reader.c (epilogue_augment): Remove, replace
9685 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
9686 * src/parse-gram.y: Adjust.
9687 (%initial-action): New.
9688 (%error-verbose): Since we require CVS Bison, there is no reason
9690 * src/scan-gram.l: Adjust.

9719 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
9720 error recovery loops. This patch is based on
9721 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
9722 Also, augment the similarity between lalr1.cc and yacc.c.
9723 Note: the locations of error recovery rules are not correct yet.
9725 * data/lalr1.cc: Comment changes to augment the similarity between
9726 lalr1.cc and yacc.c.
9727 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
9728 (yyerrlab1): Remove, but where it used to be (now the bottom part of
9729 yyerrlab), when hitting EOF, pop the whole stack here instead of
9730 merely falling thru the default error handling mechanism.
9731 (yyerrorlab): New label, with the old contents of YYERROR,
9732 plus the following change: pop the stack of rhs corresponding
9733 to the production that invoked YYERROR. That is how Yacc
9734 behaves (required by POSIX).
9735 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
9738 2003-08-25 Akim Demaille <akim@epita.fr>
9740 Tune local.at so that people can "autom4te -l autotest calc.at -o
9741 calc" for instance, to extract a sub test suite.
9743 * tests/testsuite.at: Move the initialization, Autotest version
9744 requirement, and AT_TESTED invocation into...
9745 * tests/local.at: here.
9746 * tests/testsuite.at: Include it for compatibility with Autoconf
9748 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
9751 2003-08-04 Paul Eggert <eggert@twinsun.com>
9753 Rework code slightly to avoid gcc -Wtraditional warnings.
9754 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
9755 The returned value is now stored in *YY0. All callers changed.
9756 * src/output.c (merge_output): Adjust to the above change.
9758 2003-07-26 Paul Eggert <eggert@twinsun.com>
9760 * data/glr.c (YYASSERT): New macro.
9761 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
9762 yyresolveStates, yyprocessOneStack):
9763 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
9764 Derived from a suggestion by Frank Heckenbach.
9766 2003-07-25 Paul Eggert <eggert@twinsun.com>
9768 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
9769 for portability to K&R C (after ansi2knr, presumably). See
9770 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
9771 by Frank Heckenbach, though I have omitted the structure-initialization
9772 part of his glr-knr.diff patch since I recall that the Portable
9773 C Compiler didn't require that change.
9775 Let the user specify how to allocate and free memory.
9776 Derived from a suggestion by Frank Heckenbach in

9778 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
9779 All uses of free, malloc, realloc changed to use these macros,
9780 and unnecessary casts removed.
9781 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
9783 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
9785 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):

9806 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
9807 yyreportTree): Do not assume that size_t is the same width as int,
9808 when printing sizes. Print sizes using an unsigned format.
9809 Problem reported by Frank Heckenbach in
9810 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
9812 Port to Forte Developer 7 C compiler.
9813 * data/glr.c (struct YYLTYPE): If locations are not being used,
9814 declare a single dummy member, as empty structs do not conform
9816 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
9817 the Forte Developer 7 C compiler complains that end-of-loop
9818 code is not reached.
9820 2003-06-17 Paul Eggert <eggert@twinsun.com>

9862 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
9863 `How Can I Reset @code{yyparse}', since texinfo does not allow
9864 arbitrary @ in node names.
9866 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
9867 shouldn't be needed according to the gettext 0.12.1 documentation
9868 but which seem to be needed anyway: codeset.m4 glibc21.m4
9869 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4

9891 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
9892 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
9893 the tests right now.
9894 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
9895 yyerror are declared before use; C99 requires this.
9897 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
9899 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
9901 (yyrecoverSyntaxError): Correct the logic for setting and testing
9903 Correct comment on handling EOF.
9904 Allow states with only a default reduction, rather than failing
9905 (I can't quite reconstruct why these were not allowed before).
9907 Fixes to avoid problem that $-N rules in GLR parsers can cause
9908 buffer overruns, corrupting state.
9910 * src/output.c (prepare_rules): Output max_left_semantic_context
9912 * src/reader.h (max_left_semantic_context): New variable declaration.
9913 * src/scan-gram.l (max_left_semantic_context): Define.

9922 * data/glr.c (YYLTYPE): Make trivial if locations not used.
9923 (YYRHSLOC): Add parentheses, and define only if locations used.
9924 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if

9927 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
9929 * tests/cxx-type.at: Exercise location information; update tests
9930 to differentiate output with and without locations.
9931 Remove forward declarations of yylex and yyerror---caused errors
9932 because default YYLTYPE not yet defined.
9933 Change semantic actions to compute strings, rather than printing
9934 them directly (to test proper passing of semantics values). Change
9935 output to prefix notation and update test data and expected results.
9936 (yylex): Track locations.
9937 (stmtMerge): Return value rather than printing, and include arguments
9940 2003-06-03 Paul Eggert <eggert@twinsun.com>
9942 Avoid warnings generated by GCC 2.95.4 when Bison is
9943 configured with --enable-gcc-warnings.

9945 yy::]b4_parser_class_name[::translate_,

9947 yy::Stack::operator[] (unsigned) const,
9948 yy::Slice::operator[] (unsigned),
9949 yy::Slice::operator[] (unsigned) const):
9950 Rename local vars to avoid warnings.
9951 * tests/glr-regression.at (Improper handling of embedded actions
9952 and $-N in GLR parsers): Remove unused local variable from yylex.
9953 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
9954 (void) as arg when not pure, since we now assume C89 when building
9955 Bison. Pacify GCC by using parameter.
9957 2003-06-02 Paul Eggert <eggert@twinsun.com>
9959 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
9960 yy::Location::lines, yy::Location::columns): Rename arguments
9961 to avoid shadowing; this removes a warning generated by GCC 3.3.
9963 2003-06-01 Paul Eggert <eggert@twinsun.com>
9965 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
9966 to g++, as GCC 3.3 complains if you do it.
9967 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
9968 everything that WARNING_CFLAGS has, except omit warnings
9969 not suitable for C++.
9970 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
9971 * tests/atlocal.in (CXXFLAGS): New var.
9972 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
9974 Fix a GLR parser bug I reported in February; see
9975 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
9976 The problem was that GLR parsers did not conform to the C standard,
9977 because actions like { $1 = $2 + $3; } expanded to expressions
9978 that invoked YYFILL in separate subexpressions, and YYFILL assigned
9979 to a local variable. The C standard says that expressions
9980 like (var = f ()) + (var = f ()) have undefined behavior.
9981 Another problem was that GCC sometimes issues warnings that
9982 yyfill and its parameters are unused.
9984 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
9986 (yyfill): New function.
9988 (yyuserAction): Change type of yynormal to bool, so that it matches
9989 the new yyfill signature. Mark it as possibly unused.
9992 Follow up on a bug I reported in February, where a Bison-generated
9993 parser can loop. Provide a test case and a fix for yacc.c. I
9994 don't have a fix for lalr1.cc or for glr.c, unfortunately.
9995 The original bug report is in:
9996 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
9998 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
9999 macro's size was becoming unwieldy.
10000 (yyerrlab): Do not discard an empty lookahead symbol, as this
10001 might destroy garbage.
10002 (yyerrorlab): New label, with the old contents of YYERROR,
10003 plus the following change: pop the stack of rhs corresponding
10004 to the production that invoked YYERROR. That is how Yacc
10005 behaves, and POSIX requires this behavior.
10006 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
10007 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
10008 Define 'alarm' to do nothing if unistd.h is not available.
10009 Add a new rule "exp: '-' error;" to test the above change to
10010 data/yacc.c. Use 'alarm' to abort any test taking longer than
10011 10 seconds, as it's probably looping.
10012 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
10013 Also, the new yacc.c generates two fewer diagnostics for an
10016 2003-05-24 Paul Eggert <eggert@twinsun.com>
10018 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
10019 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
10020 This fixes a problem reported by John Bowman when the Compaq/HP
10021 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
10022 -ansi -Wall -gall).
10023 * data/yacc.c (union yyalloc): Likewise.
10024 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
10026 Switch from 'int' to 'bool' where that makes sense.
10028 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
10029 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
10030 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,
10031 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
10032 Return or accept bool, not int. All callers changed.
10033 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
10034 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.

10036 bitset_copy_, bitset_op4_cmp, bitset_and_or_cmp_, bitset_andn_or_cmp_,

10038 * lib/bitset.h (bitset_test, bitset_only_set_p): Likewise.
10039 * lib/bitset_stats.c (bitset_stats_print, bitset_stats_toggle,
10040 bitset_stats_test, bitset_stats_empty_p, bitset_stats_disjoint_p,

10043 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
10044 bitset_stats_or_and_cmp): Likewise.
10045 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,
10046 ebitset_test, ebitset_empty_p, ebitset_subset_p, ebitset_disjoint_p,
10047 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
10048 ebitset_xor_cmp): Likewise.
10049 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
10050 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
10051 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
10052 lbitset_xor_cmp): Likewise.
10053 * lib/bbitset.h: Include <stdbool.h>.
10054 (struct bitset_vtable): The following members now return bool, not
10055 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
10056 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
10058 * src/conflicts.c (count_rr_conflicts): Likewise.
10059 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
10061 * lib/ebitset.c (ebitset_obstack_init): Likewise.
10062 * lib/lbitset.c (lbitset_obstack_init): Likewise.
10063 * src/getargs.c (debug_flag, defines_flag, locations_flag,
10064 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
10065 graph_flag): Likewise.
10066 * src/getargs.h (debug_flag, defines_flag, locations_flag,
10067 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
10068 graph_flag): Likewise.
10069 * src/output.c (error_verbose): Likewise.
10070 * src/output.h (error_verbose): Likewise.
10071 * src/reader.c (start_flag, typed): Likewise.
10072 * src/reader.h (typed): Likewise.
10073 * src/getargs.c (LOCATIONS_OPTION): New constant.
10074 (long_options, getargs): Use it.
10075 * src/lalr.c (build_relations): Use bool, not int.
10076 * src/nullable.c (nullable_compute): Likewise.
10077 * src/print.c (print_reductions): Likewise.
10078 * src/tables.c (action_row, pack_vector): Likewise.
10079 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
10080 * src/output.c (prepare): Use it.
10081 * src/output.c (token_definitions_output,
10082 symbol_destructors_output, symbol_destructors_output): Use string,
10083 not boolean integer, to keep track of whether to output separator.
10084 * src/print_graph.c (print_core): Likewise.
10085 * src/state.c (state_rule_lookaheads_print): Likewise.
10087 * config/install-sh: Sync from automake 1.7.5.
10089 2003-05-14 Paul Eggert <eggert@twinsun.com>
10091 * src/parse-gram.y (rules_or_grammar_declaration): Require a
10092 semicolon after a grammar declaration, in the interest of possible
10093 future changes to the Bison input language.
10094 Do not allow a stray semicolon at the start of the grammar.
10095 (rhses.1): Allow one or more semicolons after any rule, including
10096 just before "|" as required by POSIX.
10097 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
10100 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
10102 %parse-param support for lalr1.cc.
10104 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
10105 b4_cc_constructor_calls, b4_cc_constructor_call,
10106 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
10108 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
10109 parse-param arguments.
10110 (yy::b4_parser_class_name): Declare instance variables to
10111 hold parse-param arguments.
10112 * tests/calc.at: s/value/semantic_value/ because value clashes
10113 with a member of yy::b4_parser_class_name. Adjust C++ code
10114 to handle %parse-param. Enable %parse-param test in C++.
10116 2003-05-12 Paul Eggert <eggert@twinsun.com>
10118 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
10119 English a bit. Fix fclose typo. Change "const char" to "char
10120 const", and use ANSI C rather than K&R for "main". Suggest
10121 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
10122 and suggest yy_switch_to_buffer.
10124 2003-05-05 Paul Eggert <eggert@twinsun.com>
10126 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
10127 C89. This avoids a diagnostic on compilers that define __STDC__
10128 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
10129 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
10131 2003-05-03 Paul Eggert <eggert@twinsun.com>
10133 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
10134 Do not overrun array bounds.
10135 This should fix a bug reported today by Olatunji Oluwabukunmi in
10136 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
10138 2003-04-29 Akim Demaille <akim@epita.fr>
10140 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
10141 * src/getargs.c, src/getargs.h: here, as bool, not int.
10142 (nondeterministic_parser): New.
10143 * src/parse-gram.y, src/scan-gram.l: Support
10144 %nondeterministic-parser.
10145 * src/output.c (prepare): Use nondeterministic_parser instead
10146 of glr_parser where appropriate.
10147 * src/tables.c (conflict_row, action_row, save_row)
10148 (token_actions, token_actions, pack_vector): Ditto.
10150 2003-04-29 Akim Demaille <akim@epita.fr>
10152 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
10154 2003-04-29 Akim Demaille <akim@epita.fr>
10156 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
10157 with %pure-parser and %locations to exercise the patch from Yakov
10160 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
10162 * data/yacc.c: (b4_lex_param): Corrected for the case where
10163 %lex-param is provided and %pure-parser isn't.
10165 2003-04-27 Paul Eggert <eggert@twinsun.com>
10167 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
10168 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
10169 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
10170 if it is not defined.
10171 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
10173 2003-04-26 Paul Eggert <eggert@twinsun.com>
10175 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
10176 Declare to be of type suitable for the ninf value itself, not of
10177 type suitable for the corresponding table, since the latter might
10178 be unsigned but the ninf value might be negative. This fixes a
10179 bug reported by Alexandre Duret-Lutz in
10180 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
10182 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
10183 invokes it. We shouldn't invoke it twice because it will attempt
10184 to put error.o in the archive twice. This fixes a glitch reported
10185 by Martin Mokrejs in
10186 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
10188 2003-04-21 Paul Eggert <eggert@twinsun.com>
10190 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
10193 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
10195 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
10196 Fix obvious typo that results in uncompilable GLR parsers
10197 when both %pure-parser and %locations are used. (trivial change)
10199 2003-04-17 Paul Eggert <eggert@twinsun.com>
10201 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
10202 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
10203 Do not insert the expected token via unput, as this runs afoul
10204 of a POSIX-compatibility bug in flex 2.5.31.
10205 All uses changed to BEGIN the parent state,
10206 since we no longer insert the expected token via unput.
10207 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
10208 that is no longer emitted after the above change.
10210 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
10211 the first one. This change is from Paul Hilfinger, and it fixes
10212 regression reported by Werner Lemberg in
10213 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
10215 (resolve_sr_conflict): Don't invoke state_errs_set
10216 unless one or more tokens have been explicitly made errors.
10217 Otherwise, the above change causes Bison to abort.
10219 * tests/existing.at (GNU pic Grammar): New test case, taken from
10222 2003-03-31 Akim Demaille <akim@epita.fr>
10224 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
10226 2003-03-31 Akim Demaille <akim@epita.fr>
10228 * src/output.c (prepare_symbols): Avoid trailing spaces in the
10231 2003-03-31 Akim Demaille <akim@epita.fr>
10233 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
10234 From Paul Hilfinger.
10236 2003-03-29 Akim Demaille <akim@epita.fr>
10238 * m4/error.m4: Do not put under dynamic conditions some code which
10239 expansion is under static control.
10241 2003-03-29 Akim Demaille <akim@epita.fr>
10243 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
10245 2003-03-29 Akim Demaille <akim@epita.fr>
10247 * doc/bison.texinfo (Strings are Destroyed): New.
10249 2003-03-13 Paul Eggert <eggert@twinsun.com>
10251 * .cvsignore: Add configure.lineno.
10252 * src/.cvsignore: Add yacc.
10253 * tests/.cvsignore: Add testsuite.log.
10254 * doc/fdl.texi: Sync with latest FSF version.
10256 2003-03-12 Paul Eggert <eggert@twinsun.com>
10258 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
10259 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
10260 cursor, instead of leaving it undefined. This fixes a bug
10261 reported by Tim Van Holder in
10262 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
10263 * tests/input.at (Torturing the Scanner): Test the scanner on
10264 an empty input file, which was Tim Van Holder's test case.
10266 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
10267 <sys/resource.h> can be included, include sys/time.h and
10268 sys/times.h first, if available. This works around the SunOS
10269 4.1.4 porting bug reported by Bruce Becker in
10270 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
10272 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
10273 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
10274 AC_HEADER_SYS_WAIT.
10276 Merge changes from gnulib. This was prompted because the CVS
10277 snapshot didn't build on Solaris 7 due to strnlen problems.
10279 These changes need to be merged back into gnulib:
10280 * lib/hash.c: Include <stdbool.h> unconditionally.
10281 * m4/onceonly.m4 (m4_quote): New macro.
10282 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
10283 Quote AC_FOREACH variable-expansions properly.
10284 The 2003-01-03 obstack.h change also needs merging.
10285 {end of changes requiring merging}
10287 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
10288 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
10289 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
10290 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
10291 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
10292 New files, imported from gnulib.
10293 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
10296 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
10297 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
10300 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
10302 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
10303 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
10304 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
10305 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
10306 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
10307 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
10308 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
10309 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
10310 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
10311 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
10312 (jm_PREREQ_ARGMATCH): Remove.
10313 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
10314 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
10316 * src/system.h: Include <stdbool.h> unconditionally.
10318 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
10319 assuming at least C89 in the bitset code for some time now.
10321 2003-03-03 Akim Demaille <akim@epita.fr>
10325 2003-03-02 Akim Demaille <akim@epita.fr>
10327 * doc/bison.texinfo (Table of Symbols): Reactivate the
10328 documentation for %lex-param, and %parse-param.
10330 2003-03-02 Akim Demaille <akim@epita.fr>
10332 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
10333 generate verbose error messages.
10334 Use the number of tokens as an upper bound in yytname, as it
10335 cannot be a non terminal.
10337 2003-03-02 Akim Demaille <akim@epita.fr>
10339 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
10342 2003-03-02 Akim Demaille <akim@epita.fr>
10344 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
10345 Use them to exercise yycheck overrun.
10346 Based on Andrew Suffield's grammar.
10348 2003-03-02 Akim Demaille <akim@epita.fr>
10350 Create tests/local.at for Bison generic testing macros.
10352 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
10353 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
10355 * tests/calc.at (AT_CHECK_CALC): Adjust.
10356 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
10357 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
10358 * tests/local.at: here.
10359 (AT_COMPILE_CXX): Tags the tests using it as c++.
10360 Ignore the test if CXX is not functional.
10362 2003-03-01 Paul Eggert <eggert@twinsun.com>
10364 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
10365 not loc->end, since loc->end might contain garbage and this leads
10366 to undefined behavior on some platforms.
10367 (id_loc, token_start): Use (IF_LINTed) initial values that do not
10368 depend on *loc, so that the reader doesn't give the the false
10369 impression that *loc is initialized.
10370 (<INITIAL>"%%"): Do not bother setting code_start, since its value
10371 does not survive the return.
10373 2003-03-01 Akim Demaille <akim@epita.fr>
10375 * src/scan-gram.l (code_start): Always initialize it when entering
10376 into yylex, as SC_EPILOGUE is activated *before* the corresponding
10377 yylex invocation. An alternative would be making it static, but
10378 then it starts with the second %%'s beginning, instead of its end.
10380 2003-02-28 Paul Eggert <eggert@twinsun.com>
10382 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
10383 around a UnixWare 7.1.1 porting bug reported by John Hughes in
10384 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
10386 2003-02-26 Paul Eggert <eggert@twinsun.com>
10388 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
10389 Remove Sequent/Pyramid discussion (nobody uses them any more).
10390 Merge VMS and MS-DOS discussion; these ports may well be dead
10391 but let's keep mentioning them for now. Put <> around email
10392 addresses. Add copyright notice.
10394 2003-02-24 Paul Eggert <eggert@twinsun.com>
10396 * data/glr.c (yy_reduce_print): yylineno -> yylno,
10397 to avoid collision with flex use of yylineno.
10398 Problem reported by Bruce Lilly in
10399 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
10400 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
10401 * data/yacc.c (yy_reduce_print): Likewise.
10403 * config/depcomp: Sync with Automake 1.7.3.
10405 2003-02-21 Akim Demaille <akim@epita.fr>
10407 * data/lalr1.cc: Use temporary variables instead of casts to
10408 change integer types.
10409 Suggested by Paul Eggert.
10411 2003-02-21 Akim Demaille <akim@epita.fr>
10413 * doc/bison.texinfo: Use "location" consistently to refer to @n,
10414 to avoid confusions with lalr1.cc's notion of Position.
10415 Suggested by Paul Eggert.
10417 2003-02-20 Akim Demaille <akim@epita.fr>
10419 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
10420 before initial_columns.
10421 (location.hh): Use consistent variable names when defining the
10423 Use "last" so that we subtract from Positions, not from unsigned.
10425 2003-02-20 Akim Demaille <akim@epita.fr>
10427 * data/lalr1.cc (position.hh): New subfile, including the extended
10428 and Doxygen'ed documentation of class Position.
10429 (location.hh): Use it.
10430 Document a` la Doxygen.
10431 With the help of Benoit Perrot.
10433 2003-02-20 Akim Demaille <akim@epita.fr>
10435 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
10437 Redefine AT_YYERROR_SEES_LOC_IF using it.
10438 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
10440 Don't use the location in yy::Parser::error_ and
10441 yy::Parser::print_ when not %locations.
10442 Activate more lalr1.cc tests.
10444 2003-02-19 Akim Demaille <akim@epita.fr>
10446 * data/lalr1.cc: When displaying a line number, be sure to make it
10449 2003-02-19 Akim Demaille <akim@epita.fr>
10451 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
10453 (YYABORT, YYACCEPT, YYERROR): New.
10454 * tests/calc.at: Renable the lalr1.cc test.
10456 2003-02-19 Akim Demaille <akim@epita.fr>
10458 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
10459 error recovery, mixing with/without pops and discarding of the
10462 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
10464 2003-02-17 Paul Eggert <eggert@twinsun.com>
10466 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
10467 * tests/testsuite.at (AT_COMPILE): Use them.
10468 This fixes the testsuite problem reported by Robert Lentz in
10469 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
10471 2003-02-12 Paul Eggert <eggert@twinsun.com>
10473 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
10474 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
10475 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
10476 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
10477 Check for malloc failure, for consistency with yacc.c.
10478 (yytname_size): Remove, for consistency with yacc.c.
10480 The bug still remains in data/lalr1.cc, as I didn't have time
10483 2003-02-06 Akim Demaille <akim@epita.fr>
10485 * configure.ac (GXX): Rename as...
10486 (CXX): this, to keep the original Autoconf semantics.
10488 * data/lalr1.cc: Fix b4_copyright invocations.
10489 If YYDEBUG is not defined, don't depend upon name_ being defined.
10490 (location.hh): Include string and iostream.
10491 (Position::filename): New member.
10492 (Position::Position ()): New.
10493 (operator<< (Position)): New.
10494 (operator- (Position, int)): New.
10495 (Location::first, Location::last): Rename as...
10496 (Location::begin, Location::end): these, to mock the conventional
10498 (operator<< (Location)): New.
10499 * tests/atlocal.in (CXX): New.
10500 * tests/testsuite.at (AT_COMPILE_CXX): New.
10501 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
10502 locations in a more synthetic way.
10503 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
10505 Adjust the C locations to match those from Emacs: first column is
10507 Change all the expected results.
10508 Conform to the GCS: simplify the locations when applicable.
10509 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
10510 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
10511 these CPP macros with the m4 macros new defined by...
10512 (AT_CHECK_PUSHDEFS): this, i.e.:
10513 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
10514 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
10516 (AT_CHECK_POPDEFS): Undefine them.
10517 (AT_CHECK_CALC_LALR1_CC): New.
10518 Use it for the first lalr1.cc test.
10520 2003-02-04 Akim Demaille <akim@epita.fr>
10522 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
10523 Location as is defined.
10525 2003-02-04 Akim Demaille <akim@epita.fr>
10527 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
10528 name_ being defined.
10530 2003-02-03 Paul Eggert <eggert@twinsun.com>
10532 * src/gram.h (start_symbol): Remove unused decl.
10534 Use more-consistent naming conventions for local vars.
10536 * src/derives.c (derives_compute): Change type of local var from
10537 int to rule_number.
10538 * src/gram.c (grammar_rules_partial_print): Likewise.
10539 * src/print.c (print_core): Likewise.
10540 * src/reduce.c (reduce_grammar_tables): Likewise.
10542 * src/gram.c (grammar_dump): Change name of item_number *
10543 local var from r to rp.
10544 * src/nullable.c (nullable_compute): Likewise.
10546 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
10548 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
10549 for symbol or symbol_number var.
10550 * src/reader.c (grammar_start_symbol_set): Likewise.
10551 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
10553 * src/state.c (transitions_to): Likewise.
10554 * src/state.h: Likewise.
10555 * src/tables.c (symbol_number_to_vector_number): Likewise.
10557 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
10560 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
10563 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
10566 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
10567 Use str, not s, for char * var. Use ch, not c, for character var.
10568 Use size for size var.
10570 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
10572 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
10574 * src/uniqstr.h: Likewise.
10576 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
10577 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
10578 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
10579 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
10580 param to have same name as that of enum, so that we don't use
10581 "s" to stand for a non-state.
10583 2003-02-02 Akim Demaille <akim@epita.fr>
10585 * src/scan-skel.l: Scan more than one inert character per yylex
10588 2003-02-01 Paul Eggert <eggert@twinsun.com>
10592 * po/LINGUAS: Add ms.
10594 2003-01-30 Akim Demaille <akim@epita.fr>
10596 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
10598 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10600 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
10603 Changes in response to error report by S. Eken: GLR mode does not
10604 handle negative $ indices or $ indices in embedded rules correctly.
10605 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
10607 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
10608 (b4_rhs_location): Ditto.
10609 (yyfill): New function to copy from stack tree into array
10611 (yyuserAction): Modify to allow incremental move of semantic values
10612 to rhs array when in GLR mode.
10613 Define YYFILL to use in user-defined actions to fill semantic array
10615 Remove dummy use of yystack, as there is now a guaranteed use.
10616 (yydoAction): Modify to allow incremental move of semantic values
10617 to rhs array when in GLR mode.
10618 (yyresolveAction): Ditto.
10619 (yyglrShiftDefer): Update comment.
10620 (yyresolveStates): Use X == NULL for pointers, not !X.
10621 (yyglrReduce): Ditto.
10622 (yydoAction): Ditto
10624 * tests/glr-regr1.at: Rename to ...
10625 * tests/glr-regression.at: Add new regression test for the problems
10626 described above (adapted from S. Eken).
10627 Update copyright notice.
10628 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
10629 * tests/Makefile.am: Ditto.
10631 2003-01-28 Paul Eggert <eggert@twinsun.com>
10633 * data/lalr1.cc: Do not use @output_header_name@ unless
10634 b4_defines_flag is set. This fixes two bugs reported by
10636 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
10637 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
10639 2003-01-21 Paul Eggert <eggert@twinsun.com>
10641 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
10642 we don't need to worry about yyerrlab1 being reported as an
10643 "unused label" by non-GCC C compilers. The downside is that if
10644 locations are used then a couple of statements are duplicated each
10645 time YYERROR is invoked, but the upside is that the warnings
10647 (yyerrlab1): Move code to YERROR.
10648 (yyerrlab2): Remove. Change uses back to yyerrlab1.
10649 This reverts some of the 2002-12-27 change.
10651 2003-01-17 Paul Eggert <eggert@twinsun.com>
10653 * src/output.c (symbol_printers_output): Fix typo that led
10654 to core dump. Problem reported by Antonio Rus in
10655 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
10657 2003-01-13 Akim Demaille <akim@epita.fr>,
10658 Quoc Peyrot <chojin@lrde.epita.fr>,
10659 Robert Anisko <anisko_r@lrde.epita.fr>
10661 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
10662 when the stacks contain one element, as the loop would otherwise
10663 free the last state, and then use the top state (the one we just
10664 popped). This means that the initial elements will not be freed
10665 explicitly, as is the case in yacc.c; it is not a problem, as
10666 these elements have fake values.
10668 2003-01-11 Paul Eggert <eggert@twinsun.com>
10670 * NEWS: %expect-violations are now just warnings, reverting
10671 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
10672 bootstrapping problem reported by Matthias Klose; see
10673 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
10674 * src/conflicts.c (conflicts_print): Likewise.
10675 * tests/conflicts.at (%expect not enough, %expect too much,
10676 %expect with reduce conflicts): Likewise.
10677 * doc/bison.texinfo (Expect Decl): Document this. Also mention
10678 that the warning is enabled if the number of conflicts changes
10679 (not necessarily increases).
10681 * src/getargs.c (version): Update copyright year.
10683 2003-01-09 Akim Demaille <akim@epita.fr>
10685 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
10687 2003-01-08 Paul Eggert <eggert@twinsun.com>
10689 * Makefile.maint (WGETFLAGS):
10690 New macro, containing "-C off" to disable proxy caches.
10691 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
10692 (rel-check): Use $(WGET) instead of wget.
10694 2003-01-06 Paul Eggert <eggert@twinsun.com>
10696 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
10697 the GLR paper of Scott, Johnstone and Hussain.
10699 2003-01-04 Paul Eggert <eggert@twinsun.com>
10701 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
10702 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
10703 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
10704 (EXTRA_LIBRARIES): New var, for liby.a.
10705 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
10706 (EXTRA_SCRIPTS): New var, for yacc.
10708 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
10709 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
10710 Problem reported by Nelson H. F. Beebe.
10712 2003-01-03 Paul Eggert <eggert@twinsun.com>
10714 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
10715 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
10716 when compiling Bison 1.875's `bitset bset = obstack_alloc
10717 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
10719 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
10720 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
10721 grow to a huge size with typical invocation.
10723 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
10724 Use the pattern recommended by Autoconf 2.57, except also protect
10725 against double-definition.
10726 * src/system.h: Likewise.
10727 Portability issues reported by Nelson H. F. Beebe.
10729 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
10730 All uses changed. Provide a definition in both C and C++.
10731 (yytrue, yyfalse): Define even if defined (__cplusplus).
10733 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
10734 Reported by Nelson H. F. Beebe.
10736 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
10738 2003-01-02 Paul Eggert <eggert@twinsun.com>
10740 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
10741 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
10742 Bug reported by Nelson H. F. Beebe.
10744 2003-01-01 Paul Eggert <eggert@twinsun.com>
10748 2002-12-30 Paul Eggert <eggert@twinsun.com>
10750 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
10752 (<INITIAL>","): Here. This causes stray "," to be treated
10755 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
10756 last brace in braced code when not in Yacc mode, for compatibility
10757 with Bison 1.35. This resurrects the 2001-12-15 patch to
10760 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
10761 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
10763 2002-12-28 Paul Eggert <eggert@twinsun.com>
10765 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
10766 that of SYM's type. This fixes Debian bug 168069, reported by
10769 2002-12-28 Paul Eggert <eggert@twinsun.com>
10773 Switch back to the Yacc style of conflict reports, undoing some
10774 of the 2002-07-30 change.
10775 * doc/bison.texinfo (Understanding): Use Yacc style for
10776 conflict reports. Also, use new way of locating rules.
10777 * src/conflicts.c (conflict_report):
10778 Renamed from conflict_report_yacc, removing the old
10779 'conflict_report'. Translate the entire conflict report at once,
10780 so that we don't assume that "," has the same interpretation in
10782 (conflicts_output): Use Yacc-style conflict report for each state,
10783 instead of our more-complicated style.
10784 (conflicts_print): Use Yacc-style conflict report, except print
10785 the input file name when not emulating Yacc.
10786 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
10787 Conflicted Reduction, %expect not enough, %expect too much,
10788 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
10789 * tests/existing.at (GNU Cim Grammar): Likewise.
10790 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
10792 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
10793 fatal): Don't invoke fflush; it's not needed and it might even be
10794 harmful for stdout, as stdout might not be open.
10795 * src/reduce.c (reduce_print): Likewise.
10797 2002-12-27 Paul Eggert <eggert@twinsun.com>
10799 Fix a bug where error locations were not being recorded correctly.
10800 This problem was originally reported by Paul Hilfinger in
10801 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
10803 * data/yacc.c (yyparse): New local var yylerrsp, to record the
10804 top of the location stack's error locations.
10805 (yyerrlab): Set it. When discarding a token, push its location
10806 onto yylerrsp so that we don't lose track of the error's end.
10807 (yyerrlab1): Now is only the target of YYERROR, so that we can
10808 properly record the location of the action that failed. For GCC
10809 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
10810 GCC warning about yyerrlab1 being unused if YYERROR is unused.
10811 (yyerrlab2): New label, which yyerrlab now falls through to.
10812 Compute the error's location by applying YYLLOC_DEFAULT to
10813 the locations of all the symbols that went into the error.
10814 * doc/bison.texinfo (Location Default Action): Mention that
10815 YYLLOC_DEFAULT is also invoked for syntax errors.
10816 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
10817 Error locations include the locations of all the tokens that were
10818 discarded, not just the last token.
10820 2002-12-26 Paul Eggert <eggert@twinsun.com>
10822 * src/files.c: Include quote.h.
10823 (compute_output_file_names): Warn if we detect conflicting
10824 outputs to the same file. This should catch the misunderstanding
10825 exemplified by Debian Bug 165349, reported by Bruce Stephens..
10827 * src/conflicts.c (conflicts_print): If the user specifies
10828 "%expect N", report an error if there are any reduce/reduce
10829 conflicts. This is what the manual says should happen.
10830 This fixes Debian bug 130890, reported by Anthony DeRobertis.
10831 * tests/conflicts.at (%expect with reduce conflicts): New test.
10833 Don't use m4_include on relative file names, as it doesn't work as
10834 desired if there happens to be a file with that name under ".".
10836 * m4sugar/version.m4: Remove; it was included but it wasn't used.
10837 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
10838 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
10839 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
10840 * src/output.c (output_skeleton): Use full path names when
10841 specifying a file to include; don't rely on include path, as
10842 it's unreliable when the working file contains a file with
10845 2002-12-25 Paul Eggert <eggert@twinsun.com>
10847 Remove obsolete references to bison.simple and bison.hairy.
10848 Problem mentioned by Aubin Mahe in
10849 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
10850 * data/glr.c: Comment fix.
10851 * doc/bison.1: Remove references. Also, mention "yacc".
10853 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
10856 * src/parse-gram.y (declaration): Use enum "report_states" rather
10857 than its numeric value 1.
10859 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
10860 opening a new one. This fixes Debian bug 165349, reported by
10863 2002-12-24 Paul Eggert <eggert@twinsun.com>
10867 * Makefile.maint (cvs-update): Don't assume that the shell
10868 supports $(...), as Solaris sh doesn't.
10870 * src/parse-gram.y (lloc_default): Remove test for empty
10871 nonterminals at the end, since it didn't change the result.
10873 2002-12-24 Paul Eggert <eggert@twinsun.com>
10875 If the user does not define YYSTYPE as a macro, Bison now declares it
10876 using typedef instead of defining it as a macro. POSIX requires this.
10877 For consistency, YYLTYPE is also declared instead of defined.
10879 %union directives can now have a tag before the `{', e.g., the
10880 directive `%union foo {...}' now generates the C code
10881 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
10882 The default union tag is `YYSTYPE', for compatibility with Solaris 9
10883 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
10884 instead of `yyltype'.
10886 `yystype' and `yyltype' are now obsolescent macros instead of being
10887 typedefs or tags; they are no longer documented and will be
10888 withdrawn in a future release.
10890 * data/glr.c (b4_location_type): Remove.
10891 (YYSTYPE): Renamed from yystype.
10892 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
10893 (struct YYLTYPE): Renamed from struct yyltype.
10894 (YYLTYPE): Renamed from yyltype.
10895 (yyltype, yystype): New (and obsolescent) macros,
10896 for backward compatibility.
10897 * data/yacc.c: Likewise.
10899 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
10900 does not specify a union tag. This is for compatibility with
10903 * src/parse-gram.y (add_param): 2nd arg is now char * not char
10904 const *, since it is now modified by stripping surrounding { }.
10905 (current_braced_code): Remove.
10906 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
10907 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
10908 trailing " {...}". Now of type <chars>.
10909 (grammar_declaration): Adjust to bundled tokens.
10910 (code_content): Remove; stripping is now done by add_param.
10911 (print_token_value): Print contents of bundled tokens.
10912 (token_name): New function.
10914 * src/reader.h (braced_code, current_braced_code): Remove.
10915 (token_name): New decl.
10917 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
10918 token_type, not braced_code code_kind. All uses changed.
10919 (SC_PRE_CODE): New state, for scanning after a keyword that
10920 has (or usually has) an immediately-following braced code.
10921 (token_type): New local var, to keep track of which token type
10922 to return when scanning braced code.
10923 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
10924 <INITIAL>"%parse-param", <INITIAL>"%printer",
10925 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
10926 instead of returning a token type immediately.
10927 (<INITIAL>"{"): Set token type.
10928 (<SC_BRACED_CODE>"}"): Use it.
10929 (handle_action_dollar, handle_action_at): Now returns bool
10930 indicating success. Fail if ! current_rule; this prevents a core dump.
10931 (handle_symbol_code_dollar, handle_symbol_code_at):
10932 Remove; merge body into caller.
10933 (handle_dollar, handle_at): Complain in invalid contexts.
10935 * NEWS, doc/bison.texinfo: Document the above.
10936 * NEWS: Fix years and program names in copyright notice.
10938 2002-12-17 Paul Eggert <eggert@twinsun.com>
10940 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
10941 Reporting, Table of Symbols): Omit mentions of %lex-param and
10942 %parse-param from the documentation for now.
10944 2002-12-15 Paul Eggert <eggert@twinsun.com>
10946 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
10947 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
10948 lookahead symbol, and which sets yychar in parser actions) and it
10949 disagreed with the Bison documentation. Bug
10950 reported by Andrew Walrond.
10952 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
10953 as the caller now does that.
10954 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
10955 (YYEMPTY): Parenthesize right hand side, since others use it.
10956 (yyparse): Don't assume that our generated code is the only code

10992 Remove unportable casts and storage allocation tricks.
10993 While we're at it, remove almost all casts, since they
10994 usually aren't needed and are a sign of trouble.
10996 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
10998 * src/derives.c (derives_compute): Do not subtract NTOKENS from
10999 the pointer DSET returned by malloc; this isn't portable.

11027 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
11030 * src/muscle_tab.c (muscle_m4_output):
11031 Now inline. Return bool, not int.
11032 * src/state.c (state_compare): Likewise.

11044 hash_symbol_hasher): Likewise.
11045 * src/uniqstr.c (uniqstr_print_processor): Likewise.
11046 * src/muscle_tab.c (muscles_m4_output):
11047 Use new functions instead of casting old functions unportably.
11048 * src/state.c (state_hash_new): Likewise.
11049 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
11050 symbols_token_translations_init):
11052 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
11054 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
11055 var instead of casting to long, to avoid casts.
11056 (prepare_states): Use MALLOC rather than alloca, so that we don't
11057 have to worry about alloca.
11058 * src/state.c (state_hash_lookup): Likewise.
11060 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
11061 local var instead of casting to unsigned char, to avoid casts.
11063 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
11064 STATE_ALLOC): Remove.
11065 (transitions_new, errs_new, reductions_new, state_new): Use malloc

11070 * src/state.c (state_hash): Use unsigned accumulator, not signed.
11072 * src/symtab.c (symbol_free): Remove; unused.

11075 hashing-related ones.
11077 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
11078 (symbol_processor): Remove.
11079 (symbols_do): Remove decl; now static.
11081 * src/system.h (alloca): Remove; decl no longer needed.
11082 (<stddef.h>): Include, for offsetof.
11083 (<inttypes.>, <stdint.h>): Include if available.
11084 (uintptr_t): New type, if system lacks it.
11085 (CALLOC, MALLOC, REALLOC): New macros.
11086 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these

11102 2002-12-09 Paul Eggert <eggert@twinsun.com>
11104 Change identifier spellings to avoid collisions with names
11105 that are reserved by POSIX.
11107 Don't use names ending in _t, since POSIX reserves them.
11108 For consistency, remove _e and _s endings -- they're weren't
11109 needed to remove ambiguity. All uses changed.
11110 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
11111 turn was just renamed from struniq_t.
11112 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
11113 which in turn was just renamed from struniq_processor_t.
11114 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which

11185 value_t_as_yystype -> value_as_yystype.
11187 Don't include <errno.h> in the mainstream code, since it
11188 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
11189 * lib/get-errno.c, lib/get-errno.h: New files.
11190 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,

11205 likewise for "STRUNIQ" and "UNIQSTR".
11206 * src/uniqstr.c: Renamed from src/struniq.c.
11207 * src/uniqstr.h: Renamed from src/struniq.h.
11208 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

11245 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
11248 Sort include-file uses.
11250 Reorder all include files under src to be in the order "system.h".
11251 then the ../lib include files in angle brackets (alphabetized),
11252 then the . include files in double-quotes (alphabetized). Fix
11253 dependency breakages encountered in this process, as follows:
11254 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
11255 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.

11258 2002-12-08 Paul Eggert <eggert@twinsun.com>
11260 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
11261 since this causes problems when __file__ contains character
11262 sequences like "@" that are treated specially by src/scan-skel.l.
11263 Instead, just use the file's basename. This fixes the bug
11264 reported by Martin Mokrejs in
11265 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
11267 2002-12-06 Paul Eggert <eggert@twinsun.com>
11269 Add support for rules that do not have trailing semicolons, as

11273 * src/location.c: Include <quotearg.h>.
11274 (empty_location): Now const.
11275 (location_print): New function. Follow the recommendation of the

11277 * src/location.h: Do not include <quotearg.h>; no longer needed.
11278 (boundary): New type.
11279 (location_t): Use it. This allows locations to span file boundaries.
11280 All member uses changed: file -> start.file or end.file (as needed),
11281 first_line -> start.line, first_column -> start.column,
11282 last_line -> end.line, last_column -> end.column.
11283 (equal_boundaries): New function.

11285 (LOCATION_PRINT): Remove. All callers changed to use location_print.
11286 (empty_location): Now const.
11287 (location_print): New decl.
11288 * src/parse-gram.y (lloc_default): New function, which handles
11289 empty locations more accurately.
11290 (YYLLOC_DEFAULT): Use it.
11291 (%token COLON): Remove.
11292 (%token ID_COLON): New token.

11300 * src/reader.h: Include location.h.
11301 (scanner_cursor): New decl.

11304 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
11306 (STEP): Remove. No longer needed, now that adjust_location does
11307 the work. All uses removed.
11308 (scanner_cursor): New var.
11309 (adjust_location): Renamed from extend_location. It now sets
11310 *loc and adjusts the scanner cursor. All uses changed.
11311 Don't bother testing for CR.
11312 (handle_syncline): Remove location arg; now updates scanner cursor.
11313 All callers changed.
11314 (unexpected_end_of_file): Now accepts start boundary of token or
11315 comment, not location. All callers changed. Update scanner cursor,
11317 (SC_AFTER_IDENTIFIER): New state.
11318 (context_state): Renamed from c_context. All uses changed.
11319 (id_loc, code_start, token_start): New local vars.
11320 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
11321 processing of Yacc white space and equivalents here.
11322 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
11323 instead of returning ID immediately, since we need to search for
11324 a subsequent colon.
11325 (<INITIAL>"'", "\""): Save token_start.
11326 (<INITIAL>"%{", "{", "%%"): Save code_start.
11327 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
11328 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
11329 BEGIN context_state at end, not INITIAL.
11330 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
11331 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
11332 Return correct token start.
11333 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
11334 the start of a character, string or multiline comment is found.
11335 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
11336 Reduction): Adjust reported locations to match the more-precise
11337 results now expected.
11338 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
11339 * tests/reduce.at (Useless Rules, Reduced Automaton,
11340 Underivable Rules): Likewise.
11341 * tests/regression.at (Invalid inputs): No longer `expecting ";"
11342 or "|"' now that so many other tokens are allowed by the new grammar.
11344 * src/complain.h (current_file): Remove duplicate decl;
11345 current_file is now owned by files.h.
11346 * src/complain.c, src/scan-gram.l: Include files.h.
11348 2002-12-06 Paul Eggert <eggert@twinsun.com>
11350 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
11351 promotes to int; it might be unsigned int.
11352 * data/yacc.c (yy_reduce_print): Likewise.
11354 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
11355 be #defined in the prologue, not in the Bison declarations.
11356 This fixes Debian Bug 102878, reported by Shaul Karl.
11358 2002-12-02 Paul Eggert <eggert@twinsun.com>
11360 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
11361 * lib/strtoul.c: New file, from gnulib.
11362 This fixes a porting bug reported by Peter Klein in
11363 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
11365 2002-11-30 Paul Eggert <eggert@twinsun.com>
11367 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
11368 and put only a forward declaration in the prologue. This is for
11369 consistency with the other scanner helper functions.
11371 Type clashes now generate warnings, not errors, since it
11372 appears that POSIX may allow some grammars with type clashes.
11373 * src/reader.c (grammar_current_rule_check): Warn about
11374 type clashes instead of complaining.
11375 * tests/input.at (Type Clashes): Expect warnings, not complaints.
11377 Add Yacc library, since POSIX requires it.
11378 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
11379 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
11380 * lib/main.c, lib/yyerror.c: New files.
11382 gram_error can be static; it need not be extern.
11383 * src/reader.h (gram_error): Remove decl.
11384 * src/parse-gram.y (gram_error): Now static. Add static decl.
11385 (print_token_value): Omit parameter names from forward decl,
11388 2002-11-29 Paul Eggert <eggert@twinsun.com>
11390 * doc/bison.texinfo: Emphasize that yylex and yyerror must
11391 be declared before being used. E.g., one should typically
11392 declare them in the prologue. Use GNU coding style in examples.
11393 Put "const" consistently after the type it modifies. Mention
11394 that C99 supports "inline". Mention that yyerror traditionally
11397 %parse-param and %lex-param now take just one argument, the
11398 declaration; the argument name is deduced from the declaration.
11400 * doc/bison.texinfo (Parser Function, Pure Calling, Error
11401 Reporting, Table of Symbols): Document this.
11402 * src/parse-gram.y (add_param): New function.
11404 (declaration): Implement new rule for %parse-param and %lex-param.
11405 * src/scan-gram.l: "," now elicits a warning, rather than being
11406 a token; this is more compatible with byacc.
11407 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
11409 2002-11-27 Paul Eggert <eggert@twinsun.com>
11411 Rename identifiers to avoid real and potential collisions.
11413 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
11414 to avoid collision with lex macro described by Bruce Lilly in
11415 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
11416 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
11417 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
11418 * src/parse-gram.y (print_token_value): Renamed from yyprint.
11420 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
11421 The name "yycontrol" violates the name space rules, and this stuff
11422 wasn't being used anyway.
11423 (input): Remove action; this stuff wasn't being used.
11424 (gram_error): Rename local variable yylloc -> loc.
11425 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
11426 (YY_DECL): Don't use "yy" at start of local variables.
11427 All uses changed, e.g., yylloc -> loc.
11428 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
11429 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
11430 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
11431 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
11433 * src/parse-gram.y (gram_error): loc is now const *.
11434 * src/reader.h (gram_error): Likewise.
11436 2002-11-24 Paul Eggert <eggert@twinsun.com>
11440 * tests/actions.at (Actions after errors): Use an output format
11441 more similar to that of the Printers and Destructors test.
11442 Test the position of the ';' token too.
11443 (Printers and Destructors): Likewise.
11444 (Printers and Destructors: %glr-parser): Remove for now, to avoid
11445 unnecessarily alarming people when the test fails.
11447 * data/yacc.c (yyerrlab1): Move this label down, so that the
11448 parser does not discard the lookahead token if the user code
11449 invokes YYERROR. This change is required for POSIX conformance.
11451 * lib/error.c: Sync with gnulib.
11453 2002-11-22 Paul Eggert <eggert@twinsun.com>
11455 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
11456 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
11457 * lib/xmalloc.c: Likewise.
11459 2002-11-20 Paul Eggert <eggert@twinsun.com>
11461 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
11463 2002-11-20 Paul Eggert <eggert@twinsun.com>
11465 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
11466 should use `if (! x) abort ();' rather than `assert (x);', and
11467 anyway it's one less thing to worry about configuring.
11469 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
11470 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
11471 and replace all instances of assert with abort.
11472 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
11473 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
11475 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
11476 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
11477 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
11478 hash_find_entry, hash_rehash, hash_insert): Likewise.
11479 * src/conflicts.c (resolve_sr_conflict): Likewise.
11480 * src/lalr.c (set_goto_map, map_goto): Likewise.
11481 * src/nullable.c (nullable_compute): Likewise.
11482 * src/output.c (prepare_rules, token_definitions_output): Likewise.
11483 * src/reader.c (packgram, reader): Likewise.

11485 state_reduction_find): Likewise.
11486 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
11487 symbol_pack): Likewise.
11488 * src/tables.c (conflict_row, pack_vector): Likewise.
11489 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
11490 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
11491 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
11492 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
11494 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
11495 (ARGMATCH_CONSTRAINT): New macro.
11496 (ARGMATCH_ASSERT): Use it.
11498 * src/system.h (verify): New macro.
11499 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
11500 rather than assert.
11501 * src/tables.c (tables_generate): Likewise.
11503 * src/struniq.c (struniq_assert): Now returns void, and aborts
11504 if the assertion is false.
11505 (struniq_assert_p): Remove.
11506 * src/struniq.h: Likewise.
11508 2002-11-18 Paul Eggert <eggert@twinsun.com>
11510 * data/glr.c (yygetLRActions): Replace `yyindex' with
11511 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
11512 This fixes the regression with Sun ONE Studio 7 cc that I reported in
11513 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
11515 2002-11-18 Akim Demaille <akim@epita.fr>
11517 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
11519 From Tim Van Holder.
11521 2002-11-17 Paul Eggert <eggert@twinsun.com>
11523 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
11524 to "SyntaxError" for consistency with my 2002-11-15 change.
11526 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
11527 not define to {}, since this breaks the common use of `YYDPRINTF
11528 ((...));' if a single statement is desired (e.g. before `else').
11529 Work around GCC warnings by surrounding corresponding calls with
11531 (yyhasResolvedValue): Remove unused function.
11532 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
11534 (yyreportSyntaxError): Renamed from yyreportParseError.
11535 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
11537 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
11538 extern when possible. Remove unused initializations.
11540 2002-11-16 Akim Demaille <akim@epita.fr>
11542 Augment the similarity between GLR and LALR traces.
11544 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
11545 (YY_REDUCE_PRINT): New.
11546 (yyparse): Use them.
11547 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
11549 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
11550 state reached after the reduction/recovery, since...
11551 (yyparse, yyprocessOneStack): Report the state we are entering in.
11553 2002-11-16 Akim Demaille <akim@epita.fr>
11555 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
11556 Add support for --trace=skeleton.
11557 * src/scan-skel.l: %option debug.
11558 Scan strings of non-@ or \n instead of character by character.
11559 (scan_skel): Handle trace_skeleton.
11561 (@output_parser_name@, @output_header_name@): ``Restore'' their
11562 support (used to be M4 macros).
11563 * data/yacc.c: Quote larger chunks, a la glr.c.
11564 * data/lalr1.cc: Likewise.
11565 The header guards are no longer available, so use some other
11566 string than `YYLSP_NEEDED'.
11568 2002-11-16 Akim Demaille <akim@epita.fr>
11570 Make the ``Printers and Destructors'' test more verbose, taking
11571 `yacc.c''s behavior as (possibly wrong) reference.
11573 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
11574 instead of fprint on stdout.
11575 Set and report the last_line of the symbols.
11576 Consistently display values and locations.
11578 2002-11-16 Paul Eggert <eggert@twinsun.com>
11580 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
11582 2002-11-15 Paul Eggert <eggert@twinsun.com>
11584 * tests/actions.at (Actions after errors): New test case.
11586 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
11587 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
11588 tests/action.at, tests/calc.at, tests/conflicts.at,
11589 tests/cxx-type.at, tests/regression.at:
11590 "parse error" -> "syntax error" for POSIX compatibility.
11591 "parsing stack overflow..." -> "parser stack overflow" so
11592 that code matches Bison documentation.
11594 2002-11-15 Akim Demaille <akim@epita.fr>
11596 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
11597 take two BRACED_CODE, not two string_content.
11598 Free the scanner's obstack when we are done.
11599 (code_content): New.
11600 * tests/calc.at: Adjust.
11601 * doc/bison.texinfo: Adjust.
11602 Also, make sure to include the `,' for these declarations.
11604 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
11606 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
11607 definition; avoids potential autoreconf problems.
11609 2002-11-15 Akim Demaille <akim@epita.fr>
11611 Always check the value returned by yyparse.
11613 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
11614 returned by yyparse.
11615 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
11617 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
11618 returned by yyparse.
11620 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11622 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
11625 2002-11-14 Paul Eggert <eggert@twinsun.com>
11627 * src/output.c (output_skeleton): Call xfopen instead of
11628 duplicating xfopen's body.
11630 Fix bugs reported by Nelson H. F. Beebe in
11631 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
11633 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
11634 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
11635 Group compiler. Instead, use "$CC -E bar.c". Include the .h
11636 file twice in the grammar, as an extra check.
11638 * tests/input.at (Torturing the Scanner): Surround the
11639 backslash-newline tests with "#if 0", to make it less likely that
11640 we'll run into compiler bugs. Bring back solitary \ inside
11641 comment, but add a closing comment to work around HP C bug. Don't
11642 test backslash-newline in C character constant.
11644 2002-11-14 Akim Demaille <akim@epita.fr>
11646 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
11647 status of the compiler.
11648 Calling `exit 1' is no longer needed.
11649 Reported by Nelson H. F. Beebe.
11651 2002-11-14 Akim Demaille <akim@epita.fr>
11653 * tests/atlocal.in (CPPFLAGS): We have config.h.

11657 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
11658 * tests/regression.at, tests/torture.at: Use them for all the
11659 grammars that are to be compiled.
11660 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
11661 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
11662 * doc/bison.texinfo (GLR Parsers): Document `inline'.
11664 2002-11-14 Akim Demaille <akim@epita.fr>
11666 * doc/bison.texinfo: Various formatting changes (alignments in
11667 samples, additional @group/@end group, GCS in samples.
11668 Use @deffn instead of simple @table to define the directives,
11669 macros, variables etc.
11671 2002-11-13 Paul Eggert <eggert@twinsun.com>
11673 Fix some bugs reported by Albert Chin-A-Young in
11674 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
11676 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
11677 -o c"; the HP C compiler chatters during compilation.
11678 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
11679 * tests/headers.at (export YYLTYPE): Likewise.
11681 * tests/input.at (Torturing the Scanner): Remove lines containing
11682 solitary backslashes, as they tickle a bug in the HP C compiler.
11684 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
11685 comments, since they're not portable. Use GNU coding style.
11687 2002-11-13 Akim Demaille <akim@epita.fr>
11689 * data/yacc.c: Leave bigger chunks of quoted text.
11690 (YYDSYMPRINTF): New.
11691 Use it to report symbol activities.
11692 * data/glr.c (YYDSYMPRINTF): New.
11695 2002-11-12 Paul Eggert <eggert@twinsun.com>
11699 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
11700 (yyglrReduce): Return yyok, not 0.
11701 This should avoid the enumerated-type warnings reported
11702 by Nelson H. F. Beebe in
11703 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.

11706 * lib/bitset.h [! BITSET_INLINE]: Remove.
11707 (bitset_set, bitset_reset, bitset_test): Rename local vars
11708 to avoid shadowing warnings by GCC.
11710 * data/glr.c (inline): Remove #define. It's the user's
11711 responsibility to #define it away, just like 'const'.
11712 This fixes one of the bugs reported by Nelson H. F. Beebe in
11713 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
11715 * Makefile.maint (po-check): Scan .l and .y files instead of the
11716 .c and the .h files that they generate. This fixes the bug
11717 reported by Tim Van Holder in:
11718 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
11719 Look for N_ as well as for _. Try to avoid matching #define for
11721 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
11722 src/system.h. Add src/parse-gram.y, src/scan-gram.l.

11724 do not confuse xgettext.
11726 * src/struniq.h (struniq_new): Do not declare the return type
11727 to be 'const'; this violates the C standard.
11728 * src/struniq.c (struniq_new): Likewise.
11730 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
11732 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
11733 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq

11738 * Makefile.maint: Sync with Autoconf:
11739 (local_updates): New.

11755 2002-11-12 Akim Demaille <akim@epita.fr>
11757 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
11758 Use it to test the GLR parser.
11760 2002-11-12 Akim Demaille <akim@epita.fr>
11762 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
11764 * data/glr.c (yystos): New.
11765 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
11766 (YYDSYMPRINT): New.
11767 (yyval): Don't define it, it is handled via M4.
11768 (yyrecoverParseError): Free verbosely the discarded symbols.
11769 * data/yacc.c (yysymprint): Remove, rather...
11770 (b4_yysymprint_generate): invoke.

11772 Accept pointers as arguments, as opposed to the version from
11774 (b4_yydestruct_generate): Likewise.
11775 * tests/cations.at (Printers and Destructors): Use Bison directives
11776 instead of CPP macros.
11777 Don't rely on internal details.
11779 2002-11-12 Akim Demaille <akim@epita.fr>
11781 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
11782 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
11783 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
11784 it against YYEMPTY and so forth), work on yytoken (i.e., set
11785 it to YYEMPTY etc.).
11786 (yydestruct): Replace with a b4_yydestruct_generate invocation.
11787 (b4_symbol_actions): Remove.
11788 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
11789 for 0, end-of-input.
11791 2002-11-12 Akim Demaille <akim@epita.fr>
11793 * doc/bison.texinfo (Destructor Decl): New.
11795 2002-11-12 Akim Demaille <akim@epita.fr>
11797 * src/tables.c (tables_generate): Use free for pointers that
11798 cannot be NULL, not XFREE.
11799 (pack_vector): Use assert, not fatal, for bound violations.
11800 * src/state.c (state_new): Likewise.
11801 * src/reader.c (reader): Likewise.
11802 * src/lalr.c (set_goto_map): Likewise.

11806 2002-11-12 Akim Demaille <akim@epita.fr>
11808 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
11810 * src/scan-gram.l (last_string): Is global to the file, not to
11812 * src/parse-gram.y (input): Don't append the epilogue here,
11813 (epilogue.opt): do it here, and free the scanner's obstack.
11814 * src/reader.c (epilogue_set): Rename as...
11815 (epilogue_augment): this.
11816 * data/c.m4 (b4_epilogue): Defaults to empty.

11829 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
11831 Use struniq for symbols.
11833 * src/symtab.h (symbol_t): The tag member is a struniq.
11834 (symbol_type_set): Adjust.
11835 * src/symtab.c (symbol_new): Takes a struniq.

11841 * src/symlist.h, src/symlist.c (symbol_list_n_type_name_get):
11843 * src/reader.h (merger_list, grammar_currentmerge_set): The name
11844 and type members are struniqs.
11845 * src/reader.c (get_merge_function)
11846 (grammar_current_rule_merge_set): Adjust.
11847 (TYPE, current_type): Are struniq.
11849 Use struniq for file names.
11851 * src/files.h, src/files.c (infile): Split into...
11852 (grammar_file, current_file): these.
11853 * src/scan-gram.c (YY_USER_INIT, handle_syncline): Adjust.
11854 * src/reduce.c (reduce_print): Likewise.
11855 * src/getargs.c (getargs): Likewise.
11856 * src/complain.h, src/complain.c: Likewise.
11857 * src/main.c (main): Call struniqs_new early enough to use it for
11859 Don't free the input file name.
11861 2002-11-12 Akim Demaille <akim@epita.fr>
11863 * src/symtab.c (symbol_free): Remove dead deactivated code:

11874 2002-11-11 Paul Eggert <eggert@twinsun.com>
11876 Revamp to fix many (but not all) of the C- and M4-related quoting
11877 problems. Among other things, this fixes the Bison bug reported
11878 by Jan Hubicka when processing the Bash grammar; see:
11879 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
11881 Use new @ escapes consistently. Represent brackets with @{ and @}
11882 rather than @<:@ and @:>@, since this works a bit better with dumb
11883 editors like vi. Represent @ with @@, since @ is now consistently
11884 an escape. Use @oline@ and @ofile@ rather than __oline__ and
11885 __ofile__, to avoid unexpected expansions. Similarly, use @output
11886 rather than #output.
11888 * data/c.m4 (b4_copyright): Omit file name from comment, since
11889 the file name could contain "*/".
11890 (b4_synclines_flag): Don't quote the 2nd argument; it should already
11891 be quoted. All uses changed.
11893 * data/glr.c: Use new @ escapes consistently.
11894 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
11895 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
11896 Remove, since they couldn't handle arbitrary characters in file
11898 * data/lalr1.cc: Likewise.
11899 * data/yacc.c: Likewise.
11901 * src/files.c (output_infix): Remove; all uses removed.
11902 * src/files.h: Likewise.
11904 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
11905 mishandled funny characters in file names, and anyway it isn't
11907 * data/yacc.c: Likewise.
11908 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
11910 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
11911 * data/yacc.c: Likewise.
11913 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
11915 (muscle_init): Quote filename as a C string.
11916 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
11917 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
11918 * src/output.c (escaped_file_name_output): New function.
11919 (prepare_symbols): Quote tokens for M4.
11920 (prepare): Don't insert output_infix, output_prefix,
11921 output_parser_name, output_header_name; this is now down by scan-skel.
11922 Insert skeleton as a C string.
11924 * src/output.c (user_actions_output, symbol_destructors_output,
11925 symbol_printers_output): Quote filenames for C and M4.
11926 * src/reader.c (prologue_augment, epilogue_set): Likewise.
11928 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
11929 escapes other than \\ and \'; this simplifies the code.
11930 (<SC_STRING>): Likewise, for \\ and \".
11931 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
11932 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
11933 Use new escapes @{ and @} for [ and ].
11935 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
11936 them with auto vars.
11937 Switch to new escape scheme, where @ is the escape character uniformly.
11938 Abort if a stray escape character is found. Avoid unbounded input
11939 buffer when parsing non-escaped text.
11941 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
11942 __oline__, #output, $@, and @{ do not have unintended meanings.
11944 2002-11-09 Paul Eggert <eggert@twinsun.com>
11946 Fix the test failure due to GCC warnings described in
11947 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
11948 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
11949 evaluate to 0 if it's impossible for NINF to be in the respective
11951 (yygetLRActions, yyrecoverParseError): Use them.
11953 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
11954 counted in the token inserted at end of file. Now takes
11955 location_t *, not location_t, so that the location can be
11956 adjusted. All uses changed.
11958 * tests/regression.at (Invalid inputs): Adjust wording in
11959 diagnostic to match the new behavior.
11961 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
11962 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
11963 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
11964 abort ();'. This reduces the runtime of the "Many lookaheads"
11965 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
11968 2002-11-07 Paul Eggert <eggert@twinsun.com>
11970 * src/parse-gram.y (CHARACTER): Remove unused token.
11973 * src/scan-gram.l: Remove stack option. We no longer use the
11974 stack, since the stack was never deeper than 1; instead, use the
11975 new auto var c_context to record the stacked value.
11977 Remove nounput option. At an unexpected end of file, we now unput
11978 the minimal input necessary to end cleanly; this simplifies the
11981 Avoid unbounded token sizes where this is easy.
11983 (unexpected_end_of_file): New function.
11984 Use it to systematize the error message on unexpected EOF.
11985 (last-string): Now auto, not static.
11986 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
11987 (scanner_last_string_free): Remove; not used.
11988 (percent_percent_count): Move decl to just before use.
11989 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
11990 not the (never otherwised-used) CHARACTER.
11992 2002-11-07 Akim Demaille <akim@epita.fr>
11994 Let yyerror always receive the msg as last argument, so that
11995 yyerror can be variadic.
11997 * data/yacc.c (b4_yyerror_args): New.
11998 Use it when calling yyerror.
11999 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.

12005 2002-11-06 Akim Demaille <akim@epita.fr>
12007 #line should have quoted strings.
12008 Ideally, this should be done by m4_quotearg.

12012 * src/output.c (symbol_printers_output)
12013 (symbol_destructors_output): Quote the file name.

12028 * src/output.c (user_actions_output): Likewise.
12029 (prepare): Define 'b4_synclines_flag'.
12030 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
12032 2002-11-06 Akim Demaille <akim@epita.fr>

12042 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12044 * src/tables.c (matching_state): Don't allow states to match if
12045 either has GLR conflict entries.
12047 2002-11-05 Paul Eggert <eggert@twinsun.com>
12049 * src/scan-gram.l: Use more accurate diagnostics, e.g.
12050 "integer out of range" rather than "invalid value".
12051 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
12054 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
12055 Also, remove one static variable in the scanner.
12057 * src/scan-gram.l (braces_level): Now auto, not static.
12058 Initialize to zero if the compiler is being picky.
12059 (INITIAL): Clear braces_level instead of incrementing it.
12060 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
12061 as POSIX 1003.1-2001 requires.
12062 * src/system.h (IF_LINT): New macro, taken from coreutils.
12063 * configure.ac: Define "lint" if --enable-gcc-warnings.
12065 2002-11-05 Akim Demaille <akim@epita.fr>
12067 * src/scan-gram.l: When it starts with `%', complain about the
12068 whole directive, not just that `invalid character: %'.
12070 2002-11-04 Akim Demaille <akim@epita.fr>
12072 * Makefile.maint: Update from Autoconf.
12073 (update, cvs-update, po-update, do-po-update): New.

12088 * src/scan-gram.l: Use [\'] instead of ['] to pacify
12091 Use quote, not quote_n since LOCATION_PRINT no longer uses the
12094 2002-11-03 Paul Eggert <eggert@twinsun.com>
12096 * src/reader.c (get_merge_function, grammar_current_rule_check):
12097 Use consistent diagnostics for reporting type name clashes.
12098 Quote the types with <>, for consistency with Yacc.
12099 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
12101 2002-11-03 Akim Demaille <akim@epita.fr>
12103 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
12105 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
12106 (b4_parse_param): Remove.
12107 Use b4_identification.
12108 Propagate b4_pure_args where needed to pass them to yyerror.
12109 * data/glr.m4 (b4_parse_param): Remove.
12110 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)

12115 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
12116 (yyreportAmbiguity): When using a pure parser, also need
12117 the location, and the parse-params.
12119 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
12120 When using a pure parser, also need the parse-params.
12122 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
12123 (%pure-parser + %parse-param) LALR and GLR parsers.
12124 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
12125 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
12126 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
12127 (_AT_DATA_CALC_Y): Equip for purity of yyerror.

12130 * doc/bison.texinfo: Untabify the whole file.
12131 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
12132 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
12133 (Error Reporting): Adjust to these new directives.
12134 Document %error-verbose, deprecate YYERROR_VERBOSE.
12136 2002-11-03 Akim Demaille <akim@epita.fr>
12138 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
12139 AT_CHECK_CALC_GLR invocations to use % directives, instead of
12140 command line options.
12141 * tests/cxx-type.at: Formatting changes.
12143 2002-11-03 Paul Eggert <eggert@twinsun.com>
12145 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
12146 to count columns correctly, and to check for invalid inputs.
12148 Use mbsnwidth to count columns correctly. Account for tabs, too.

12150 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
12151 (extend_location): New function.
12152 (YY_LINES): Remove.
12154 Handle CRLF in C code rather than in Lex code.

12156 (no_cr_read): New function.
12158 Scan UCNs, even though we don't fully handle them yet.
12159 (convert_ucn_to_byte): New function.
12161 Handle backslash-newline correctly in C code.
12162 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
12163 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
12165 (tag, splice): New EREs. Do not allow NUL or newline in tags.
12166 Use {splice} wherever C allows backslash-newline.
12167 YY_STEP after space, newline, vertical-tab.
12168 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
12170 (letter, id): Don't assume ASCII; e.g., spell out a-z.
12172 ({int}, handle_action_dollar, handle_action_at): Check for integer
12175 (YY_STEP): Omit trailing semicolon, so that it's more like C.
12177 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
12178 as well as \000. Check for UCHAR_MAX, not 255.
12179 Allow \x with an arbitrary positive number of digits, as in C.
12180 Check for overflow here.
12181 Allow \? and UCNs, for compatibility with C.
12183 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
12184 with quote slot used by complain_at.
12186 * tests/input.at: Add tests for backslash-newline, m4 quotes
12187 in symbols, long literals, and funny escapes in strings.

12196 (Symbols): Document that trigraphs have no special meaning in Bison,
12197 nor is backslash-newline allowed.
12198 (Actions): Document that trigraphs have no special meaning.
12200 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
12203 2002-11-02 Paul Eggert <eggert@twinsun.com>
12205 * src/reader.c: Don't include quote.h; not needed.
12206 (get_merge_function): Reword warning to be consistent with
12207 type clash diagnostic in grammar_current_rule_check.
12209 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
12210 bug in trigraph handling.
12212 * src/output.c (prepare_symbols): When printing token names,
12213 escape "[" as "@<:@" and likewise for "]".
12215 * src/system.h (errno): Remove declaration, as we are now
12216 assuming C89 or better, and C89 guarantees errno.
12218 2002-10-30 Paul Eggert <eggert@twinsun.com>
12220 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
12221 Check for close failures.
12222 * src/files.h (xfclose): Return void, not int, since it always
12224 * src/files.c (xfclose): Likewise. Report I/O error if ferror
12226 * src/output.c (output_skeleton): Use xfclose rather than fclose
12227 and ferror. xfclose now checks ferror.
12229 * data/glr.c (YYLEFTMOST_STATE): Remove.
12230 (yyreportTree): Use a stack-based leftmost state. This avoids
12231 our continuing battles with bogus warnings about initializers.
12233 2002-10-30 Akim Demaille <akim@epita.fr>
12235 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only

12240 * tests/glr-regr1.at: New test for reported regressions.
12241 * tests/testsuite.at: Add glr-regr1.at test.
12242 * tests/Makefile.am: Add glr-regr1.at test.

12248 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
12249 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
12250 we use malloc. Don't assume 'A' through 'Z' are contiguous.
12251 Don't assume strdup exists; POSIX says its an XSI extension.
12252 Check for buffer overflow on input.
12254 2002-10-24 Akim Demaille <akim@epita.fr>
12256 * src/output.c (output_skeleton): Don't disable M4sugar comments
12257 too soon: it results in comments being expanded.
12258 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
12261 2002-10-24 Akim Demaille <akim@epita.fr>
12263 * data/yacc.c (m4_int_type): New.
12264 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
12265 char' as only yacc.c wants K&R portability.
12266 * data/glr.c (yysigned_char): Remove.
12267 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
12268 Reported by Quoc Peyrot.
12270 2002-10-23 Paul Eggert <eggert@twinsun.com>
12272 * src/main.c (main): With --trace=time, report times even if a
12273 non-fatal error occurs. Formerly, the times were reported in some
12274 such cases but not in others.
12275 * src/reader.c (reader): Just return if a complaint has been issued,
12276 instead of exiting, so that 'main' can report times.
12278 2002-10-22 Akim Demaille <akim@epita.fr>
12280 * src/system.h: Include sys/types.
12281 Reported by Bert Deknuydt.
12283 2002-10-23 Paul Eggert <eggert@twinsun.com>
12285 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
12286 Suggested by Art Haas.
12288 2002-10-22 Paul Eggert <eggert@twinsun.com>
12290 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
12291 decl; not needed any more.
12292 * src/main.c (main): Use return to exit, undoing yesterday's change.
12293 The last OS that we could find where this wouldn't work is
12294 SunOS 3.5, and that's too old to worry about now.
12296 * data/glr.c (struct yyltype): Define members even when not
12297 doing locations. This is more consistent with yacc.c, and it
12298 works around the following bug reports:
12299 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
12300 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
12302 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
12303 @acronym consistently. Standardize on "Yacc" instead of "YACC",
12304 "Algol" instead of "ALGOL". Give a bit more history about BNF.
12306 2002-10-22 Akim Demaille <akim@epita.fr>
12308 * data/README: New.
12310 2002-10-21 Paul Eggert <eggert@twinsun.com>
12312 Be consistent about 'bool'; the old code used an enum in one
12313 module and an int in another, and this violates the C standard.
12314 * m4/stdbool.m4: New file, from coreutils 4.5.3.
12315 * configure.ac (AC_HEADER_STDBOOL): Add.
12316 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
12317 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
12318 * src/symtab.c (hash_compare_symbol_t): Likewise.
12319 * src/system.h (bool, false, true): Use a definition consistent
12320 with ../lib/hash.c. All uses changed.
12322 * src/complain.c (warning_issued): Renamed from warn_message_count,
12323 so that we needn't worry about integer overflow (!).
12324 Now of type bool. All uses changed.
12325 (complaint_issued): Renamed from complain_message_count; likewise.
12327 * src/main.c (main): Use exit to exit with failure.
12329 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
12330 rather than 1 and 0.
12331 * src/main.c (main): Likewise.
12332 * src/getargs.c (getargs): Likewise.
12333 * src/reader.c (reader): Likewise.
12335 * src/getarg.c (getargs): Remove duplicate code for
12336 "Try `bison --help'".
12338 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
12339 What was that "2" for?
12341 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
12342 * src/getargs.c (usage): Likewise.
12344 * src/getargs.c (getargs): When there are too few operands, report
12345 the last one. When there are too many, report the first extra
12346 one. This is how diffutils does it.
12348 2002-10-20 Paul Eggert <eggert@twinsun.com>
12350 Remove K&R vestiges.
12351 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.

12355 fatal): Assume prototypes.
12356 * src/complain.h: Assume prototypes.
12357 * src/system.h (PARAMS): Remove.
12358 Include <limits.h> unconditionally, since it's guaranteeed even
12359 for a freestanding C89 compiler.
12360 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
12361 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.

12369 (yyprocessOneStack): Use them.
12370 (yy_reduce_print): New.
12371 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
12373 2002-10-20 Akim Demaille <akim@epita.fr>
12375 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
12376 arguments and output `void'.
12377 (b4_c_function): Rename as...
12378 (b4_c_function_def): this.
12379 (b4_c_function_decl, b4_c_ansi_function_def)
12380 (b4_c_ansi_function_decl): New.
12381 Change the interpretation of the arguments: before `int, foo', now

12384 Adjust b4_c_function_def uses.
12385 * data/glr.c (yyparse): Likewise, but ANSI only.
12387 2002-10-20 Akim Demaille <akim@epita.fr>
12389 * src/output.c (prepare): Move the definition of `tokens_number',
12390 `nterms_number', `undef_token_number', `user_token_number_max'
12392 (prepare_tokens): Here.
12393 (prepare_tokens): Rename as...
12394 (prepare_symbols): this.
12395 (prepare): Move the definition of `rules_number' to...
12396 (prepare_rules): here.
12397 (prepare): Move the definition of `last', `final_state_number',
12398 `states_number' to...
12399 (prepare_states): here.
12400 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
12402 2002-10-20 Akim Demaille <akim@epita.fr>
12404 * src/tables.h, src/tables.c, src/output.c: Comment changes.
12406 2002-10-20 Akim Demaille <akim@epita.fr>

12416 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
12418 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
12419 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
12422 2002-10-19 Paul Eggert <eggert@twinsun.com>
12424 Do not create a temporary file, as that involves security and
12425 cleanup headaches. Instead, use a pair of pipes.
12426 Derived from a suggestion by Florian Krohm.
12427 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
12428 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
12429 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
12430 (BISON_PREREQ_SUBPIPE): Add.
12431 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
12432 Add subpipe.h, subpipe.c.

12440 Check for pipe I/O error.
12441 * src/scan-skel.l (readpipe): Remove decl.
12442 (scan_skel): New function, to be used in place of m4_invoke.
12443 Read from stream rather than file.
12445 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
12446 float, as this generates a warning on Solaris 8 + GCC 3.2 with
12447 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
12448 this generates a more-accurate value anyway.
12450 * lib/timevar.c (timervar_accumulate): Rename locals to
12451 avoid confusion with similarly-named more-global.
12452 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
12454 * src/output.c (prepare): Use xstrdup to convert char const *
12455 to char *, to avoid GCC warning.
12457 2002-10-19 Akim Demaille <akim@epita.fr>
12459 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
12460 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
12461 Use them to have `calc.y' ready for %pure-parser.
12462 * data/yacc.c (YYLEX): Pass a yylex return type to
12463 b4_c_function_call.
12465 2002-10-19 Akim Demaille <akim@epita.fr>
12467 Prototype support of %lex-param and %parse-param.
12469 * src/parse-gram.y: Add the definition of the %lex-param and
12470 %parse-param tokens, plus their rules.
12471 Drop the `_' version of %glr-parser.
12473 * src/scan-gram.l (INITIAL): Scan them.
12474 * src/muscle_tab.c: Comment changes.
12475 (muscle_insert, muscle_find): Rename `pair' as `probe'.
12476 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
12477 (muscle_entry_s): The `value' member is no longer const.
12478 Adjust all dependencies.
12479 * src/muscle_tab.c (muscle_init): Adjust: use
12480 MUSCLE_INSERT_STRING.
12481 Initialize the obstack earlier.
12482 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
12483 (muscle_pair_list_grow): New.
12484 * data/c.m4 (b4_c_function_call, b4_c_args): New.
12485 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
12486 * tests/calc.at: Use %locations, not --locations.
12487 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
12489 2002-10-19 Akim Demaille <akim@epita.fr>
12491 * src/getargs.c (usage): Take status as argument and exit
12493 Report the traditional `Try ... --help' message when status != 0.
12494 (usage, version): Don't take a FILE * as arg, it is pointless.
12495 (getargs): When there is an incorrect number of arguments, make it
12496 an error, and report it GNUlically thanks to `usage ()'.
12498 2002-10-18 Paul Eggert <eggert@twinsun.com>
12500 * data/glr.c (yyreportParseError): Don't assume that sprintf
12501 yields the length of the printed string, as this is not true
12502 on SunOS 4.1.4. Reported by Peter Klein.
12504 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
12505 * tests/conflicts.at (%nonassoc and eof): Likewise.
12506 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
12508 2002-10-17 Akim Demaille <akim@epita.fr>
12510 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
12511 * src/getargs.c (trace_types, trace_args): Adjust.
12512 * src/reader.c (grammar_current_rule_prec_set)
12513 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
12514 Standardize error messages.
12515 And s/@prec/%prec/!
12516 (reader): Use trace_flag to enable scanner/parser debugging,
12517 instead of an adhoc scheme.
12518 * src/scan-gram.l: Remove trailing debugging code.
12520 2002-10-16 Paul Eggert <eggert@twinsun.com>
12522 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
12525 * NEWS: Officially drop support for building Bison with K&R C,
12526 since it didn't work anyway and it's not worth worrying about.
12527 * Makefile.maint (wget_files): Remove ansi2knr.c.
12528 (ansi2knr.c-url_prefix): Remove.
12529 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
12530 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
12531 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
12533 2002-10-15 Paul Eggert <eggert@twinsun.com>
12535 Stop using the "enum_" trick for K&R-style function definitions;
12536 it confused me, and I was the author! Instead, assume that people
12537 who want to use K&R C compilers (when using these modules in GCC,
12538 perhaps?) will run ansi2knr.
12540 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
12541 All uses of "enum_" changed to "enum ".
12542 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
12543 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
12545 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

12552 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
12553 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
12554 Use function prototypes; this removes the need for declaring
12555 static functions simply to provide their prototypes.
12556 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

12630 tests/cxx-type.at, tests/headers.at, tests/input.at,
12631 tests/regression.at, tests/synclines.at, tests/torture.at:
12632 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
12633 so that the tests still work even if POSIXLY_CORRECT is set.
12634 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
12636 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
12637 for portability to K&R hosts. Fix typo: signed char is guaranteed
12638 only to 127, not to 128.
12639 * data/glr.c (yysigned_char): New type.
12640 * data/yacc.c (yysigned_char): Likewise.
12641 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
12643 2002-10-13 Paul Eggert <eggert@twinsun.com>
12645 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
12646 true due to limited range of data type" warning from GCC.
12648 * data/c.m4 (b4_token_defines): Protect against double-inclusion
12649 by wrapping enum yytokentype's definition inside #ifndef
12650 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
12652 2002-10-13 Akim Demaille <akim@epita.fr>
12654 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
12655 Un yy- yyrhs to avoid the name clash with the global YYRHS.
12657 2002-10-13 Akim Demaille <akim@epita.fr>
12659 * Makefile.maint: Update from Autoconf 2.54.
12660 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
12662 2002-10-13 Akim Demaille <akim@epita.fr>
12664 * src/print.c (print_state): Separate the list of solved conflicts
12665 from the other items.
12666 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
12668 2002-10-13 Akim Demaille <akim@epita.fr>
12670 Let nondeterministic skeletons be usable with deterministic
12673 With the patch, GAWK compiled by GCC without -O2 passes its test
12674 suite using a GLR parser driven by LALR tables. It fails with -O2
12675 because `struct stat' gives two different answers on my machine:
12676 88 (definition of an auto var) and later 96 (memset on this var).
12677 Hence the stack is badly corrumpted. The headers inclusion is to
12678 blame: if I move the awk.h inclusion before GLR's system header
12679 inclusion, the two struct stat have the same size.
12681 * src/tables.c (pack_table): Always create conflict_table.
12682 (token_actions): Always create conflict_list.
12683 * data/glr.c (YYFLAG): Remove, unused.
12685 2002-10-13 Akim Demaille <akim@epita.fr>
12687 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
12689 (VALGRIND, GXX): New.
12690 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
12691 * tests/bison.in: Run $PREBISON a pre-command.
12692 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
12693 (maintainer-check-g++): New.
12694 * Makefile.am (maintainer-check): New.
12696 2002-10-13 Akim Demaille <akim@epita.fr>
12698 * data/glr.c: Formatting changes.
12699 Tweak some trace messages to match yacc.c's.
12701 2002-10-13 Akim Demaille <akim@epita.fr>
12703 GLR parsers sometimes raise parse errors instead of performing the
12705 Reported by Charles-Henry de Boysson.
12707 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
12708 check the length of the traces when %glr.
12709 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
12711 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
12713 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
12714 (yyltype): Remove the yy prefix from the member names.
12715 (yytable): Complete its comment.
12716 (yygetLRActions): Map error action number from YYTABLE from
12718 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
12719 (which was a bug: it should have been YYTABEL_NINF, and yet it was
12720 not satisfying as we could compare an YYACTION computed from
12721 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
12722 only value for error actions.
12723 (yyreportParseError): In verbose parse error messages, don't issue
12724 `error' in the list of expected tokens.
12725 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
12726 next action to perform to match glr.c's decoding.
12727 (yytable): Complete its comment.

12731 Fix problem reported by Henrik Grubbstroem in
12732 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
12733 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
12734 because the Bison parser reads the second action before reducing
12736 * src/scan-gram.l (rule_length): New static var.
12737 Use it to keep track of the rule length in the scanner, since
12738 we can't expect the parser to be in lock-step sync with the scanner.
12739 (handle_action_dollar, handle_action_at): Use this var.
12740 * tests/actions.at (Exotic Dollars): Test for the problem.
12742 2002-10-12 Paul Eggert <eggert@twinsun.com>
12744 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
12745 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
12746 Include <sys/time.h> when checking for clock_t and struct tms.
12747 Use same include order as source.
12748 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
12749 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
12751 * lib/timevar.c: Update copyright date and clarify comments.
12752 (get_time) [IN_GCC]: Keep the GCC version for reference.
12754 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
12755 GCC version as of today, then merge Bison's changes.
12756 Change "GCC" to "Bison" in copyright notice. timevar.def's
12757 author is Akim, so change that too.
12759 * src/reader.c (grammar_current_rule_check):
12760 Don't worry about the default action if $$ is untyped.
12761 Prevents bogus warnings reported by Jim Gifford in
12762 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
12764 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
12765 * data/glr.c, data/lalr1.cc, data/yacc.c:
12766 Output token definitions before the first part of user declarations.
12767 Fixes compatibility problem reported by Jim Gifford for kbd in
12768 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
12770 2002-10-11 Paul Eggert <eggert@twinsun.com>
12772 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
12773 (yyparse): here. This undoes some of the 2002-07-25 change.
12774 Compatibility problem reported by Ralf S. Engelschall with
12775 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
12777 2002-10-11 Akim Demaille <akim@epita.fr>

12788 2002-10-10 Paul Eggert <eggert@twinsun.com>
12790 Portability fixes for bitsets; this also avoids several GCC
12793 * lib/abitset.c: Include <stddef.h>, for offsetof.
12794 * lib/lbitset.c: Likewise.
12796 * lib/abitset.c (abitset_bytes): Return a size that is aligned
12797 properly for vectors of objects. Do not assume that adding a
12798 header size to a multiple of a word size yields a value that is
12799 properly aligned for the whole union.
12800 * lib/bitsetv.c (bitsetv_alloc): Likewise.
12802 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
12803 unique names for structures.
12804 * lib/ebitset.c (ebitset_bytes): Likewise.
12805 * lib/lbitset.c (lbitset_bytes): Likewise.
12807 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,

12813 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
12814 to improve the type-checking that GCC can do.

12816 * lib/bitset_stats.c (bitset_stats_count,
12817 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,

12833 * lib/lbitset.h: Likewise.
12835 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
12836 All instances of parameters of type enum bitset_opts are now of
12837 type enum_bitset_opts, to conform to the C Standard, and similarly
12838 for enum_bitset_type.
12839 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
12840 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
12842 Do not use "struct bitset_struct" to mean different things in
12843 different modules. Not only is this confusing, it violates
12844 the C Standard, which requires that structure types in different
12845 modules must be compatible if one is to be passed to the other.
12846 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
12847 All instances of "struct bitset_struct *" replaced with "bitset".
12848 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
12849 (union bitset_union, struct abitset_struct, struct ebitset_struct,
12850 struct lbitset_struct, struct bitset_stats_struct): New types.
12851 All uses of struct bitset_struct changed to union bitset_union,

12856 struct bitset_struct): Remove.
12857 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
12858 bitset_struct): Remove.
12859 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
12862 Do not call a function of type T using a call that assumes the
12863 function is of a different type U. Standard C requires that a
12864 function must be called with a type that is compatible with its
12866 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
12868 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
12870 * lib/ebitset.c (PFV): Remove.
12871 * lib/lbitset.c (PFV): Likewise.

12886 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
12887 Use offsetof, for simplicity.
12889 2002-10-06 Paul Eggert <eggert@twinsun.com>
12891 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
12892 the same width as int. This reapplies a hunk of the 2002-08-12 patch
12893 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
12894 which was inadvertently undone by the 2002-09-30 patch.
12895 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
12896 the same width as int.
12898 2002-10-04 Paul Eggert <eggert@twinsun.com>
12902 * configure.ac (AC_INIT), NEWS: Increment version number.
12904 * doc/bison.texinfo: Minor spelling, grammar, and white space
12906 (Symbols): Mention that any negative value returned from yylex
12907 signifies end-of-input. Warn about negative chars. Mention
12908 the portable Standard C character set.
12910 The GNU coding standard says CFLAGS and YFLAGS are reserved
12911 for the installer to set.
12912 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
12913 * src/Makefile.am (AM_CFLAGS): Likewise.
12914 (AM_YFLAGS): Renamed from YFLAGS.
12916 Fix some MAX and MIN problems.

12919 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
12920 * src/reader.c (reader): Use it.
12922 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
12923 POSIX 1003.1-2001 has removed fgrep.
12925 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
12927 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
12928 interpreted as signed.

13254 outside the C locale.

13257 this is a GCC extension and is not portable to other compilers.

13270 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
13271 exit status as failure, not just exit status 1. Sun C exits
13272 with status 2 sometimes.

13442 parsers now contain `reduce 0' as default reduction.

13490 yycontrol without making too strong assumptions on the parser

13493 token_translations instead of `0'.
13494 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
13496 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
13497 for the time being: %locations ought to provide it to yyerror.
13499 2002-07-25 Akim Demaille <akim@epita.fr>
13501 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

13516 Handle the `- 1' part in rule numbers from/to item numbers.

15157 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
15158 etc. instead of 10, 20, 30 (which was used to `jump' over error
15159 (256) and undefined (2)).

15198 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
15199 full stderr, and strip it according to the bison options, instead
15200 of composing the error message from different bits.
15201 This makes it easier to check for several error messages.
15202 Adjust all the invocations.
15203 Add an invocation exercising the error token.
15204 Add an invocation demonstrating a stupid error message.
15205 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

15223 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
15224 `user_token_number_max'.
15225 Output `undef_token_number'.

15265 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
15266 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
15267 passes, but produces negative #line number, once fixed, GCC is

15470 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
15471 lacking `+ 1' to nrules, Bison reported as useless a token if it
15472 was used solely to set the precedence of the last rule...
15474 2002-04-07 Akim Demaille <akim@epita.fr>
15476 * data/bison.c++, data/bison.simple: Don't output the current file
15477 name in #line, to avoid useless diffs between two identical
15478 outputs under different names.

15482 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

15498 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
15499 RHS, instead of being an index in RITEMS.
15501 2002-04-04 Paul Eggert <eggert@twinsun.com>
15503 * doc/bison.texinfo: Update copyright date.
15504 (Rpcalc Lexer, Symbols, Token Decl): Don't assume ASCII.

16058 * tests/Makefile.am (package.m4): Create it by hand,
16059 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
16061 2002-01-06 Akim Demaille <akim@epita.fr>
16063 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
16066 2002-01-04 Paul Eggert <eggert@twinsun.com>
16068 * doc/bison.texinfo (Debugging):
16069 Remove YYSTDERR; it's no longer defined or used.
16070 Also, s/cstdio.h/cstdio/.
16072 2002-01-03 Akim Demaille <akim@epita.fr>
16074 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
16076 2002-01-03 Akim Demaille <akim@epita.fr>
16078 * src/parse-skel.y (process_skeleton): Don't bind the parser's
16079 tracing code to --trace, wait for a better --trace option, with
16082 2002-01-03 Akim Demaille <akim@epita.fr>
16084 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
16085 The ISO C++ standard is extremely clear about it: stderr is
16086 considered a macro, not a regular symbol (see table 94 `Header
16087 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
16088 Therefore std:: does not apply to it. It still does with fprintf.
16089 Also, s/cstdio.h/cstdio/.
16091 2002-01-03 Akim Demaille <akim@epita.fr>
16093 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
16094 for non system headers.
16096 2002-01-02 Akim Demaille <akim@epita.fr>
16098 Equip the skeleton chain with location tracking, runtime trace,
16099 pure parser and scanner.
16101 * src/parse-skel.y: Request a pure parser, locations, and prefix
16103 (%union): Having several members with the same type does not help
16104 type mismatches, simplify.
16105 (YYPRINT, yyprint): New.
16106 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
16107 (skel_error): this.
16109 * src/scan-skel.l: Adjust to these changes.
16110 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
16111 (LOCATION_PRINT, skel_control_t): New.
16113 2001-12-30 Akim Demaille <akim@epita.fr>
16115 * src/parse-skel.y: Get rid of the shift/reduce conflict:
16116 replace `gb' with BLANKS.
16117 * src/scan-skel.l: Adjust.
16119 2001-12-30 Akim Demaille <akim@epita.fr>
16121 * src/system.h: We don't need nor want bcopy.
16122 Throw away MS-DOS crap: we don't need getpid.
16123 * configure.in: We don't need strndup. It was even causing
16124 problems: because Flex includes the headers *before* us,
16125 _GNU_SOURCE is not defined by config.h, and therefore strndup was
16127 * lib/xstrndup.c: New.
16128 * src/scan-skel.l: Use it.
16129 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
16130 * src/parse-skel.y: Use %directives instead of #defines.
16132 2001-12-30 Akim Demaille <akim@epita.fr>
16134 * src/skeleton.h: New.
16135 * src/output.c (output_parser, output_master_parser): Remove, dead
16137 * src/output.h (get_lines_number, actions_output, guards_output)
16138 (token_definitions_output): Prototype them.
16139 * src/parse-skel.y: Add the license notice.
16140 Include output.h and skeleton.h.
16141 (process_skeleton): Returns void, and takes a single parameter.
16142 * src/scan-skel.l: Add the license notice.
16143 Include skeleton.h.
16144 Don't use %option yylineno: it seems that then Flex imagines
16145 REJECT has been used, and therefore it won't reallocate its
16146 buffers (which makes no other sense to me than a bug). It results
16147 in warnings for `unused: yy_flex_realloc'.
16149 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
16151 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
16152 (MUSCLE_INSERT_PREFIX): ...to there.
16153 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
16154 (MUSCLE_INSERT_PREFIX): Move from here...
16156 * src/bison.hairy: Add a section directive. Put braces around muscle
16157 names. This parser skeleton is still broken, but Bison should not
16158 choke on a bad muscle 'syntax'.
16159 * src/bison.simple: Add a section directive. Put braces around muscle
16162 * src/files.h (strsuffix, stringappend): Add declarations.
16163 (tab_extension): Add declaration.
16164 (short_base_name): Add declaration.
16166 * src/files.c (strsuffix, stringappend): No longer static. These
16167 functions are used in the skeleton parser.
16168 (tab_extension): New.
16169 (compute_base_names): Use the computations done in this function
16170 to guess if the generated parsers should have '.tab' in their
16172 (short_base_name): No longer static.
16174 * src/output.c (output_skeleton): New.
16175 (output): Disable call to output_master_parser, and give a try to
16176 a new skeleton handling system.
16177 (guards_output, actions_output): No longer static.
16178 (token_definitions_output, get_lines_number): No longer static.
16180 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
16182 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
16185 * src/parse-skel.y: New file.
16186 * src/scan-skel.l: New file.
16188 2001-12-29 Akim Demaille <akim@epita.fr>
16190 %name-prefix is broken.
16192 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
16193 Adjust all dependencies.
16194 * tests/headers.at (export YYLTYPE): Strengthen this test: use
16197 Renaming yylval but not yylloc is not consistent. Now we do.
16199 * src/bison.simple: Prefix yylloc if used.
16200 * doc/bison.texinfo (Decl Summary): Document that.
16202 2001-12-29 Akim Demaille <akim@epita.fr>
16204 * doc/bison.texinfo: Promote `%long-directive' over
16206 Remove all references to fixed-output-files, yacc is enough.
16208 2001-12-29 Akim Demaille <akim@epita.fr>
16210 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
16211 user prologue. These are defaults.
16212 * tests/actions.at (Mid-rule actions): Make sure the user can
16213 define YYDEBUG and YYERROR_VERBOSE.
16215 2001-12-29 Akim Demaille <akim@epita.fr>
16217 * src/output.c (header_output): Don't forget to export YYLTYPE and
16219 * tests/headers.at (export YYLTYPE): New, make sure it does.
16220 * tests/regression.at (%union and --defines, Invalid CPP headers):
16222 * tests/headers.at: here.
16224 2001-12-29 Akim Demaille <akim@epita.fr>
16226 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
16228 2001-12-29 Akim Demaille <akim@epita.fr>
16230 * tests/actions.at (Mid-rule actions): Output on a single line
16231 instead of several.
16233 2001-12-29 Akim Demaille <akim@epita.fr>
16235 * doc/bison.texinfo: Formatting changes.
16237 2001-12-29 Akim Demaille <akim@epita.fr>
16239 Don't store the token defs in a muscle, just be ready to output it
16240 on command. Now possible via `symbols'. Fixes a memory leak.
16242 * src/output.c (token_definitions_output): New.
16243 (output_parser, header_output): Use it.
16244 * src/reader.c (symbols_save): Remove.
16246 2001-12-29 Akim Demaille <akim@epita.fr>
16248 * src/bison.simple: Do not provide a default for YYSTYPE and
16249 YYLTYPE before the user's prologue. Otherwise it's hardly... a
16252 2001-12-29 Akim Demaille <akim@epita.fr>
16254 Mid-rule actions are simply... ignored!
16256 * src/reader.c (readgram): Be sure to attach mid-rule actions to
16257 the empty-rule associated to the dummy symbol, not to the host
16259 * tests/actions.at (Mid-rule actions): New.
16261 2001-12-29 Akim Demaille <akim@epita.fr>
16265 * src/reader.c (reader): Free grammar.
16267 2001-12-29 Akim Demaille <akim@epita.fr>
16271 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
16272 since it allocates it for each state, although only one is needed.
16273 (allocate_storage): Do it here.
16275 2001-12-29 Akim Demaille <akim@epita.fr>
16277 * src/options.h, src/options.c (create_long_option_table): Rename
16279 (long_option_table_new): this, with a clearer prototype.
16280 (percent_table): Remove, unused,
16281 * src/getargs.c (getargs): Adjust.
16283 2001-12-29 Akim Demaille <akim@epita.fr>
16285 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
16286 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
16289 2001-12-29 Akim Demaille <akim@epita.fr>
16291 * src/lalr.c (build_relations): Rename `states' as `states1'.
16292 Sorry, I don't understand exactly what it is, no better name...
16294 2001-12-29 Akim Demaille <akim@epita.fr>
16296 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
16297 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
16298 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
16301 2001-12-29 Akim Demaille <akim@epita.fr>
16303 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
16306 2001-12-29 Akim Demaille <akim@epita.fr>
16308 * src/reader.c, src/reader.h (user_toknums): Remove.
16309 Adjust all users to use symbols[i]->user_token_number.
16311 2001-12-29 Akim Demaille <akim@epita.fr>
16313 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
16314 Adjust all users to use symbols[i]->prec or ->assoc.
16316 2001-12-29 Akim Demaille <akim@epita.fr>
16318 * src/reader.c, src/reader.h (tags): Remove.
16319 Adjust all users to use symbols[i]->tag.
16321 2001-12-29 Akim Demaille <akim@epita.fr>
16323 * src/gram.h, src/gram.c (symbols): New, similar to state_table
16325 * src/reader.c (packsymbols): Fill this table.
16327 * src/conflicts.c (resolve_sr_conflict): Adjust.
16328 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
16330 Use symbols[i]->tag instead of tags[i].
16332 2001-12-29 Akim Demaille <akim@epita.fr>
16334 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
16335 In addition, put a comment in there, to replace...
16336 * tests/regression.at (%union and C comments): Remove.
16338 2001-12-29 Akim Demaille <akim@epita.fr>
16340 * tests/regression.at (Web2c Actions): Blindly move the actual
16341 output as expected output. The contents *seem* right to me, but I
16342 can't pretend reading perfectly parser tables... Nonetheless, all
16343 the other tests pass correctly, the table look OK, even though the
16344 presence of `$axiom' is to be noted: AFAICS it is useless (but
16347 2001-12-29 Akim Demaille <akim@epita.fr>
16349 * src/reader.c (readgram): Don't add the rule 0 if there were no
16350 rules read. In other words, add it _after_ having performed
16351 grammar sanity checks.
16352 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
16354 2001-12-29 Akim Demaille <akim@epita.fr>
16356 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
16357 visible, and some states have now a different number.
16359 2001-12-29 Akim Demaille <akim@epita.fr>
16361 * src/reader.c (readgram): Bind the initial rule's lineno to that
16363 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
16364 (Solved SR Conflicts): Adjust rule 0's line number.
16366 2001-12-29 Akim Demaille <akim@epita.fr>
16368 Fix the `GAWK Grammar' failure.
16370 * src/LR0.c (final_state): Initialize to -1 so that we do compute
16371 the reductions of the first state which was mistakenly confused
16372 with the final state because precisely final_state was initialized
16374 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
16375 now noticed by Bison.
16376 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
16377 have a reduction on $default.
16379 2001-12-29 Akim Demaille <akim@epita.fr>
16381 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
16383 * src/closure.c (print_closure): Likewise.
16384 * src/derives.c (print_derives): Likewise.
16385 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
16388 2001-12-29 Akim Demaille <akim@epita.fr>
16390 * src/lalr.c (lookaheads_print): New.
16391 (lalr): Call it when --trace-flag.
16392 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
16395 2001-12-29 Akim Demaille <akim@epita.fr>
16397 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
16398 when walking through ritem, even via rule->rhs.
16399 * src/reduce.c (dump_grammar, useful_production, reduce_output)
16400 (useful_production, useless_nonterminals): Likewise.
16401 (reduce_grammar_tables): Likewise, plus update nritems.
16402 * src/nullable.c (set_nullable): Likewise.
16403 * src/lalr.c (build_relations): Likewise.
16404 * tests/sets.at (Nullable): Adjust.
16405 Fortunately, now, the $axiom is no longer nullable.
16407 2001-12-29 Akim Demaille <akim@epita.fr>
16409 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
16411 * src/gram.c (ritem_longest_rhs): Likewise.
16412 * src/reduce.c (nonterminals_reduce): Likewise.
16413 * src/print_graph.c (print_graph): Likewise.
16414 * src/output.c (output_rule_data): Likewise.
16415 * src/nullable.c (set_nullable): Likewise.
16417 2001-12-29 Akim Demaille <akim@epita.fr>
16419 * src/output.c: Comment changes.
16421 2001-12-27 Paul Eggert <eggert@twinsun.com>
16423 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
16424 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
16425 Sparc, as they were causing more porting problems than the
16426 (minor) performance improvement was worth.
16428 Also, catch up with 1.31's YYSTD.
16430 2001-12-27 Akim Demaille <akim@epita.fr>
16432 * src/output.c (output_gram): Rely on nritems, not the
16433 0-sentinel. See below.
16434 Use -1 as separator, not 0.
16435 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
16436 Rely on -1 as separator in yyrhs, instead of 0.
16437 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
16438 twice `Now at end of input', therefore there are two lines less to
16441 2001-12-27 Akim Demaille <akim@epita.fr>
16443 * tests/regression.at (Unresolved SR Conflicts):
16444 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
16447 2001-12-27 Akim Demaille <akim@epita.fr>
16449 * src/LR0.c (new_state): Recognize the final state by the fact it
16450 is reached by eoftoken.
16451 (insert_start_shifting_state, insert_eof_shifting_state)
16452 (insert_accepting_state, augment_automaton): Remove, since now
16453 these states are automatically computed from the initial state.
16454 (generate_states): Adjust.
16455 * src/print.c: When reporting a rule number to the user, substract
16456 1, so that the axiom rule is rule 0, and the first user rule is 1.
16457 * src/reduce.c: Likewise.
16458 * src/print_graph.c (print_core): For the time being, just as for
16459 the report, depend upon --trace-flags to dump the full set of
16461 * src/reader.c (readgram): Once the grammar read, insert the rule
16462 0: `$axiom: START-SYMBOL $'.
16463 * tests/set.at: Adjust: rule 0 is now displayed, and since the
16464 number of the states has changed (the final state is no longer
16465 necessarily the last), catch up.
16467 2001-12-27 Akim Demaille <akim@epita.fr>
16469 Try to make the use of the eoftoken valid. Given that its value
16470 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
16471 is used instead of > 0 where appropriate, (ii), depend upon nritems
16472 instead of the 0-sentinel.
16474 * src/gram.h, src/gram.c (nritems): New.
16475 Expected to be duplication of nitems, but for the time being...
16476 * src/reader.c (packgram): Assert nritems and nitems are equal.
16477 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
16478 * src/closure.c (print_closure, print_fderives): Likewise.
16479 * src/gram.c (ritem_print): Likewise.
16480 * src/print.c (print_core, print_grammar): Likewise.
16481 * src/print_graph.c: Likewise.
16483 2001-12-27 Akim Demaille <akim@epita.fr>
16485 * src/main.c (main): If there are complains after grammar
16486 reductions, then output the report anyway if requested, then die.
16487 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
16488 * src/reader.c (eoftoken): New.
16489 (parse_token_decl): If the token being defined has value `0', it
16491 (packsymbols): No longer hack `tags' to insert `$' by hand.
16492 Be sure to preserve the value of the eoftoken.
16493 (reader): Make sure eoftoken is defined.
16494 Initialize nsyms to 0: now eoftoken is created just like the others.
16495 * src/print.c (print_grammar): Don't special case the eof token.
16496 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
16497 lie anyway, albeit pleasant.
16498 * tests/calc.at: Exercise error messages with eoftoken.
16499 Change the grammar so that empty input is invalid.
16500 Adjust expectations.
16501 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
16503 2001-12-27 Akim Demaille <akim@epita.fr>
16505 * configure.in: Check the protos of strchr ans strspn.
16506 Replace strchr if needed.
16507 * src/system.h: Provide the protos of strchr, strspn and memchr if
16509 * lib/strchr.c: New.
16510 * src/reader.c (symbols_save): Use strchr.
16512 2001-12-27 Akim Demaille <akim@epita.fr>
16514 * src/print.c, src/print_graph.c (escape): New.
16515 Use it to quote the TAGS outputs.
16516 * src/print_graph.c (print_state): Now errors are in red, and
16517 reductions in green.
16518 Prefer high to wide: output the state number on a line of its own.
16520 2001-12-27 Akim Demaille <akim@epita.fr>
16522 * src/state.h, src/state.c (reductions_new): New.
16523 * src/LR0.c (set_state_table): Let all the states have a
16524 `reductions', even if reduced to 0.
16525 (save_reductions): Adjust.
16526 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
16527 * src/print.c (print_reductions, print_actions): Adjust.
16528 * src/output.c (action_row): Adjust.
16530 2001-12-27 Akim Demaille <akim@epita.fr>
16532 * src/state.h, src/state.c (errs_new, errs_dup): New.
16533 * src/LR0.c (set_state_table): Let all the states have an errs,
16534 even if reduced to 0.
16535 * src/print.c (print_errs, print_reductions): Adjust.
16536 * src/output.c (output_actions, action_row): Adjust.
16537 * src/conflicts.c (resolve_sr_conflict): Adjust.
16539 2001-12-27 Akim Demaille <akim@epita.fr>
16541 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
16543 2001-12-27 Akim Demaille <akim@epita.fr>
16545 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
16546 * src/print.c: here.
16547 (lookaheadset, shiftset): New, used as additional storage by
16549 (print_results): Adjust.
16550 (print_shifts, print_gotos, print_errs): New, extracted from...
16551 (print_actions): here.
16552 * src/print_graph.c (print_actions): Remove dead code.
16554 2001-12-27 Akim Demaille <akim@epita.fr>
16556 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
16559 2001-12-27 Akim Demaille <akim@epita.fr>
16561 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
16562 (build_relations): Adjust.
16564 2001-12-27 Akim Demaille <akim@epita.fr>
16566 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
16569 2001-12-27 Akim Demaille <akim@epita.fr>
16571 * src/reader.c (packgram): Catch nitems overflows.
16573 2001-12-27 Akim Demaille <akim@epita.fr>
16575 * src/files.c, src/files.h (guard_obstack): Remove.
16576 * src/output.c (output): Adjust.
16577 * src/reader.c (parse_braces): New, factoring...
16578 (copy_action, copy_guard): these two which are renamed as...
16579 (parse_action, parse_guard): these.
16580 As a voluntary consequence, using braces around guards is now
16583 2001-12-27 Akim Demaille <akim@epita.fr>
16585 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
16586 * src/reader.c (symbol_list): `guard' and `guard_line' are new
16588 (symbol_list_new): Adjust.
16589 (copy_action): action_line is the first line, not the last.
16590 (copy_guard): Just as for actions, store the `action' only, not
16591 the switch/case/break flesh.
16592 Don't parse the user action that might follow the guard, let...
16593 (readgram): do it, i.e., now, there can be an action after a
16595 In other words the guard is just explicitly optional.
16596 (packgram): Adjust.
16597 * src/output.c (guards_output): New.
16598 (output_parser): Call it when needed.
16599 (output): Also free the guard and attrs obstacks.
16600 * src/files.c, src/files.h (obstack_save): Remove.
16601 (output_files): Remove.
16602 As a result, if one needs the former `.act' file, using an
16603 appropriate skeleton which requires actions and guards is now
16605 * src/main.c (main): Adjust.
16606 * tests/semantic.at: New.
16607 * tests/regression.at: Use `input.y' as input file name.
16608 Avoid 8+3 problems by requiring input.c when the test needs the
16611 2001-12-27 Akim Demaille <akim@epita.fr>
16613 * src/reader.c (symbol_list_new): Be sure to initialize all the
16616 2001-12-27 Akim Demaille <akim@epita.fr>
16618 All the hacks using a final pseudo state are now useless.
16620 * src/LR0.c (set_state_table): state_table holds exactly nstates.
16621 * src/lalr.c (nLA): New.
16622 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
16623 instead of lookaheadsp from the pseudo state (nstate + 1).
16625 2001-12-27 Akim Demaille <akim@epita.fr>
16627 * src/output.c (action_row, token_actions): Use a state_t instead
16628 of a integer, and nlookaheads instead of the following state's
16631 2001-12-27 Akim Demaille <akim@epita.fr>
16633 * src/conflicts.c (log_resolution, flush_shift)
16634 (resolve_sr_conflict, set_conflicts, solve_conflicts)
16635 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
16636 (conflicts_print, print_reductions): Use a state_t instead of an
16637 integer when referring to a state.
16638 As much as possible, depend upon nlookaheads, instead of the
16639 `lookaheadsp' member of the following state (since lookaheads of
16640 successive states are successive, the difference between state n + 1
16641 and n served as the number of lookaheads for state n).
16642 * src/lalr.c (add_lookback_edge): Likewise.
16643 * src/print.c (print_core, print_actions, print_state)
16644 (print_results): Likewise.
16645 * src/print_graph.c (print_core, print_actions, print_state)
16646 (print_graph): Likewise.
16647 * src/conflicts.h: Adjust.
16649 2001-12-27 Akim Demaille <akim@epita.fr>
16651 * src/bison.hairy: Formatting/comment changes.
16653 Remove `register' indications.
16654 Add plenty of `static'.
16656 2001-12-27 Akim Demaille <akim@epita.fr>
16658 * src/output.c (prepare): Drop the muscle `ntbase' which
16659 duplicates ntokens.
16660 * src/bison.simple: Formatting/comment changes.
16661 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
16662 is an undocumented synonym.
16664 2001-12-22 Akim Demaille <akim@epita.fr>
16666 * src/output.c (output_table_data): Change the prototype to use
16667 `int' for array ranges: some invocations do pass an int, not a
16669 Reported by Wayne Green.
16671 2001-12-22 Akim Demaille <akim@epita.fr>
16673 Some actions of web2c.y are improperly triggered.
16674 Reported by Mike Castle.
16676 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
16677 * tests/regression.at (Web2c): Rename as...
16678 (Web2c Report): this.
16679 (Web2c Actions): New.
16681 2001-12-22 Akim Demaille <akim@epita.fr>
16683 Reductions in web2c.y are improperly reported.
16684 Reported by Mike Castle.
16686 * src/conflicts.c (print_reductions): Fix.
16687 * tests/regression.at (Web2c): New.
16689 2001-12-18 Akim Demaille <akim@epita.fr>
16691 Some host fail on `assert (!"foo")', which expands to
16692 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
16693 Reported by Nelson Beebee.
16695 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
16696 `#define it_succeeded 0' and `assert (it_succeeded)'.
16698 2001-12-17 Marc Autret <autret_m@epita.fr>
16700 * src/bison.simple: Don't hard code the skeleton line and filename.
16701 * src/output.c (output_parser): Rename 'line' as 'output_line'.
16702 New line counter 'skeleton_line' (skeleton-line muscle).
16704 2001-12-17 Paul Eggert <eggert@twinsun.com>
16706 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
16707 YYDEBUG must be defined to a nonzero value.
16709 * src/bison.simple (yytname): Do not assume that the user defines
16710 YYDEBUG to a properly parenthesized expression.
16712 2001-12-17 Akim Demaille <akim@epita.fr>
16714 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
16715 nlookaheads is a new member.
16717 * src/lalr.h (nlookaheads): Remove this orphan declaration.
16718 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
16721 2001-12-17 Akim Demaille <akim@epita.fr>
16723 * src/files.h, src/files.c (open_files, close_files): Remove.
16724 * src/main.c (main): Don't open/close files, nor invoke lex_free,
16726 * src/reader.c (reader): Do it.
16728 2001-12-17 Akim Demaille <akim@epita.fr>
16730 * src/conflicts.c (print_reductions): Formatting changes.
16732 2001-12-17 Akim Demaille <akim@epita.fr>
16734 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
16735 (flush_reduce): New.
16736 (resolve_sr_conflict): Adjust.
16738 2001-12-17 Akim Demaille <akim@epita.fr>
16740 * src/output.c (output_obstack): Be static and rename as...
16741 (format_obstack): this, to avoid any confusion with files.c's
16743 * src/reader.h (muscle_obstack): Move to...
16744 * src/output.h: here, since it's defined in output.c.
16746 2001-12-17 Akim Demaille <akim@epita.fr>
16748 * src/output.c (action_row, save_column, default_goto)
16749 (sort_actions, matching_state, pack_vector): Better variable
16752 2001-12-17 Akim Demaille <akim@epita.fr>
16754 * src/output.c: Various formatting changes.
16756 2001-12-17 Akim Demaille <akim@epita.fr>
16758 * src/files.c (output_files): Free the output_obstack.
16759 * src/main.c (main): Call print and print_graph conditionally.
16760 * src/print.c (print): Work unconditionally.
16761 * src/print_graph.c (print_graph): Work unconditionally.
16762 * src/conflicts.c (log_resolution): Output only if verbose_flag.
16764 2001-12-16 Marc Autret <autret_m@epita.fr>
16766 * src/output.c (actions_output): Fix. When we use %no-lines,
16767 there is one less line per action.
16769 2001-12-16 Marc Autret <autret_m@epita.fr>
16771 * src/bison.simple: Remove a useless #line directive.
16772 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
16773 * src/output.c (get_lines_number): New.
16774 (output_parser): Adjust, now takes care about the lines of a
16776 Fix line numbering.
16777 (actions_output): Computes the number of lines taken by actions.
16778 (output_master_parser): Insert new skeleton which is the name of
16779 the output parser file name.
16781 2001-12-15 Marc Autret <autret_m@epita.fr>
16783 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
16785 2001-12-15 Marc Autret <autret_m@epita.fr>
16787 * src/output.c (output_gram): Keep track of the hairy one.
16789 2001-12-15 Akim Demaille <akim@epita.fr>
16791 Make `make distcheck' work.
16793 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
16794 system.h which uses libgettext.h.
16796 2001-12-15 Akim Demaille <akim@epita.fr>
16798 * src/nullable.c (set_nullable): Useless rules must be skipped,
16799 otherwise, since we range over their symbols, we might look at a
16800 nonterminal which no longer ``exists'', i.e., it is not counted in
16801 `nvars', hence we overflow our arrays.
16803 2001-12-15 Akim Demaille <akim@epita.fr>
16805 The header can also be produced directly, without any obstack!
16808 * src/files.c, src/files.h (defines_obstack): Remove.
16809 (compute_header_macro): Global.
16810 (defines_obstack_save): Remove.
16811 * src/reader.c (parse_union_decl): No longer output to
16812 defines_obstack: its content can be found in the `stype' muscle
16814 (output_token_translations): Merge into...
16815 (symbols_output): this.
16817 (symbols_save): this.
16819 * src/output.c (header_output): New.
16822 2001-12-15 Akim Demaille <akim@epita.fr>
16824 * src/reader.c (parse_union_decl): Instead of handling two obstack
16825 simultaneously, use one to define the `stype' muscle, and use the
16826 value of the latter to fill defines_obstack.
16827 (copy_comment): Remove.
16828 (copy_comment2): Work for a single obstack.
16830 (copy_comment): this.
16832 2001-12-15 Akim Demaille <akim@epita.fr>
16834 * src/lex.c, src/lex.h (xgetc): No longer static.
16835 * src/reader.c (parse_union_decl): Revamp.
16837 2001-12-15 Akim Demaille <akim@epita.fr>
16839 Still making progress in separating Bison into (i) input, (ii)
16840 process, (iii) output: now we can directly output the parser file
16841 without using table_obstack at all.
16843 * src/files.c, src/files.h (table_obstack): Bye bye.
16844 (parser_file_name): New.
16845 * src/files.c (compute_output_file_names): Compute it.
16846 * src/output.c (actions_output, output_parser)
16847 (output_master_parser): To a file instead of an obstack.
16849 2001-12-15 Akim Demaille <akim@epita.fr>
16851 Attach actions to rules, instead of pre-outputting them to
16854 * src/gram.h (rule_t): action and action_line are new members.
16855 * src/reader.c (symbol_list): Likewise.
16856 (copy_action): Save the actions within the rule.
16857 (packgram): Save them in rule_table.
16858 * src/output.c (actions_output): New.
16859 (output_parser): Use it on `%%actions'.
16860 (output_rule_data): Don't free rule_table.
16862 (prepare): Don't save the `action' muscle.
16863 * src/bison.simple: s/%%action/%%actions/.
16865 2001-12-15 Akim Demaille <akim@epita.fr>
16867 * src/reader.c (copy_action): When --yacc, don't append a `;'
16868 to the user action: let it fail if lacking.
16869 Suggested by Arnold Robbins and Tom Tromey.
16871 2001-12-14 Akim Demaille <akim@epita.fr>
16873 * src/lex.c (literalchar): Simply return the char you decoded, non
16874 longer mess around with obstacks and int pointers.
16875 Adjust all callers.
16877 2001-12-14 Akim Demaille <akim@epita.fr>
16879 * src/lex.c (literalchar): Don't escape the special characters,
16880 just decode them, and keep them as char (before, eol was output as
16881 the 2 char string `\n' etc.).
16882 * src/output.c (output_rule_data): Use quotearg to output the
16885 2001-12-13 Paul Eggert <eggert@twinsun.com>
16887 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
16888 Do not infringe on the global user namespace when using C++.
16889 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
16890 All uses of `fprintf' and `stderr' changed.
16892 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
16894 2001-12-13 Akim Demaille <akim@epita.fr>
16896 The computation of nullable is broken: it doesn't handle empty
16899 * tests/torture.at (GNU AWK Grammar): New.
16900 * tests/sets.at (Nullable): New.
16901 * src/nullable.c (set_nullable): Instead of blindly looping over
16902 `ritems', loop over the rules, and then over their rhs's.
16904 Work around Autotest bugs.
16906 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
16907 frame, because Autotest understand lines starting with a `+' as
16908 traces from the shell. Then, they are not processed properly.
16909 Admittedly an Autotest bug, but we don't have time to wait for
16910 Autotest to catch up.
16911 * tests/regression.at (Broken Closure): Adjust to the new table
16914 * tests/sets.at: here.
16916 2001-12-13 Akim Demaille <akim@epita.fr>
16918 * src/closure.c (closure): Use nrules instead of playing tricks
16919 with BITS_PER_WORD.
16921 2001-12-13 Akim Demaille <akim@epita.fr>
16923 * src/print.c (print_actions): Output the handling of `$' as the
16924 traces do: shifting the token EOF. Before EOF was treated as a
16926 * tests/regression.at: Adjust some tests.
16927 * src/print_graph.c (print_core): Complete the set of items via
16928 closure. The next-to-final and final states are still unsatisfying,
16929 but that's to be addressed elsewhere.
16930 No longer output the rule numbers, but do output the state number.
16931 A single loop for the shifts + gotos is enough, but picked a
16932 distinct color for each.
16933 (print_graph): Initialize and finalize closure.
16935 2001-12-13 Akim Demaille <akim@epita.fr>
16937 * src/reader.c (readgram): Remove dead code, an strip useless
16939 (get_type): Remove, unused.
16941 2001-12-12 Akim Demaille <akim@epita.fr>
16943 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
16944 on that of lib/error.c.
16946 2001-12-12 Akim Demaille <akim@epita.fr>
16948 Some hosts don't like `/' in includes.
16950 * src/system.h: Include libgettext.h without qualifying the path.
16951 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
16954 2001-12-11 Marc Autret <autret_m@epita.fr>
16956 * src/output.c (output_parser): Remove useless muscle.
16958 2001-12-11 Marc Autret <autret_m@epita.fr>
16960 * src/bison.simple: Remove #line just before %%epilogue. It
16961 is now handled in ...
16962 * src/reader.c (read_additionnal_code): Add the output of a
16963 #line for the epilogue.
16965 2001-12-10 Marc Autret <autret_m@epita.fr>
16967 * src/reader.c (copy_definition): Re-use CPP-outed code which
16968 replace precedent remove.
16969 * src/bison.simple: Remove #line before %%prologue because
16970 %%input-line is wrong at this time.
16972 2001-12-10 Marc Autret <autret_m@epita.fr>
16974 * src/reader.c (symbols_output): Clean up.
16975 * src/output.c (output_gram, output): Clean up.
16977 2001-12-10 Akim Demaille <akim@epita.fr>
16979 * src/lalr.c (initialize_lookaheads): New. Extracted from...
16980 * src/LR0.c (set_state_table): here.
16981 * src/lalr.c (lalr): Call it.
16983 2001-12-10 Akim Demaille <akim@epita.fr>
16985 * src/state.h (shifts): Remove the `number' member: shifts are
16986 attached to state, hence no longer need to be labelled with a
16989 2001-12-10 Akim Demaille <akim@epita.fr>
16991 Now that states have a complete set of members, the linked list of
16992 shifts is useless: just fill directly the state's shifts member.
16994 * src/state.h (shifts): Remove the `next' member.
16995 * src/LR0.c (first_state, last_state): Remove.
16996 Adjust the callers.
16997 (augment_automaton): Don't look for the shifts that must be added
16998 a shift on EOF: it is those of the state we looked for! But now,
16999 since shifts are attached, it is no longer needed to looking
17000 merely by its id: its number.
17002 2001-12-10 Akim Demaille <akim@epita.fr>
17004 * src/LR0.c (augment_automaton): Better variable locality.
17005 Remove an impossible branch: if there is a state corresponding to
17006 the start symbol being shifted, then there is shift for the start
17007 symbol from the initial state.
17009 2001-12-10 Akim Demaille <akim@epita.fr>
17011 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
17012 only when appropriate: when insert_start_shifting_state' is not
17014 * tests/regression.at (Rule Line Numbers): Adjust.
17016 2001-12-10 Akim Demaille <akim@epita.fr>
17018 * src/LR0.c (augment_automaton): Now that all states have shifts,
17019 merge the two cases addition shifts to the initial state.
17021 2001-12-10 Akim Demaille <akim@epita.fr>
17023 * src/lalr.c (set_state_table): Move to...
17025 * src/lalr.c (lalr): Don't call it...
17026 * src/LR0.c (generate_states): do it.
17027 * src/LR0.h (first_state): Remove, only the table is used.
17029 2001-12-10 Akim Demaille <akim@epita.fr>
17031 * src/LR0.h (first_shift, first_reduction): Remove.
17032 * src/lalr.c: Don't use first_shift: find shifts through the
17035 2001-12-10 Akim Demaille <akim@epita.fr>
17037 * src/LR0.c: Attach shifts to states as soon as they are
17039 * src/lalr.c (set_state_table): Instead of assigning shifts to
17040 state, just assert that the mapping was properly done.
17042 2001-12-10 Akim Demaille <akim@epita.fr>
17044 * src/LR0.c (insert_start_shift): Rename as...
17045 (insert_start_shifting_state): this.
17046 (insert_eof_shifting_state, insert_accepting_state): New.
17047 (augment_automaton): Adjust.
17048 Better locality of the variables.
17049 When looking if the start_symbol is shifted from the initial
17050 state, using `while (... symbol != start_symbol ...)' sounds
17051 better than `while (... symbol < start_symbol ...)': If fail
17052 to see how the order between symbols could be relevant!
17054 2001-12-10 Akim Demaille <akim@epita.fr>
17056 * src/getargs.h: Don't declare `spec_name_prefix' and
17057 `spec_file_prefix', declared by src/files.h.
17058 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
17059 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
17060 * src/output.c (prepare): Adjust.
17061 * src/reader.c (symbols_output): Likewise.
17062 * src/vmsgetargs.c: Vaguely adjust, but who cares?
17064 2001-12-10 Akim Demaille <akim@epita.fr>
17066 * src/muscle_tab.c (muscle_init): NULL is a better default than
17069 2001-12-10 Akim Demaille <akim@epita.fr>
17071 * src/reader.c (reader): Calling symbols_output once is enough.
17073 2001-12-10 Akim Demaille <akim@epita.fr>
17075 Now that states have a complete set of members, the linked list of
17076 reductions is useless: just fill directly the state's reductions
17079 * src/state.h (struct reductions): Remove member `number' and
17081 * src/LR0.c (first_reduction, last_reduction): Remove.
17082 (save_reductions): Don't link the new reductions, store them in
17084 * src/lalr.c (set_state_table): No need to attach reductions to
17085 states, it's already done.
17086 * src/output.c (output_actions): No longer free the shifts, then
17087 the reductions, then the states: free all the states and their
17090 2001-12-10 Akim Demaille <akim@epita.fr>
17092 * src/options.c (OPTN, DRTV, BOTH): New.
17093 (option_table): Use them.
17095 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
17096 the job of system.h.
17097 * src/options.c: Don't include stdio.h and xalloc.h for the same
17100 2001-12-10 Akim Demaille <akim@epita.fr>
17102 * src/output.c (output, prepare): Make sure the values of the
17103 muscles `action' and `prologue' are 0-terminated.
17105 2001-12-10 Akim Demaille <akim@epita.fr>
17107 Clean up GCC warnings.
17109 * src/reader.c (copy_action): `buf' is not used.
17110 (parse_skel_decl): Be static.
17111 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
17112 * src/options.h (create_long_option_table): Have a real prototype.
17113 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)

17117 2001-12-10 Akim Demaille <akim@epita.fr>
17119 * configure.in: Require 2.52g.
17120 M4 is not needed, but AUTOM4TE is.
17121 * m4/m4.m4: Remove.
17122 * tests/Makefile.am: Adjust.
17124 2001-12-10 Akim Demaille <akim@epita.fr>
17126 One structure for states is enough, even though theoretically
17127 there are LR(0) states and LALR(1) states.
17129 * src/lalr.h (state_t): Remove.
17130 (state_table): Be state_t **, not state_t *.
17131 * src/state.h (core, CORE_ALLOC): Rename as...
17132 (state_t, STATE_ALLOC): this.
17133 Add the LALR(1) members: shifts, reductions, errs.
17134 * src/LR0.c (state_table): Rename as...
17135 (state_hash): this, to avoid name clashes with the global
17137 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
17138 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
17140 2001-12-10 Akim Demaille <akim@epita.fr>
17142 Bison dumps core on bash.y.
17143 Reported by Pascal Bart.
17145 * src/warshall.c (bitmatrix_print): New.
17147 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
17148 j must be the outer loop.
17149 * tests/regression.at (Broken Closure): New.
17151 2001-12-05 Akim Demaille <akim@epita.fr>
17153 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
17155 Reported by Peter Hamorsky.

17160 (resolve_sr_conflict): Adjust.
17161 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
17163 (state_t.reductions, state_t.shifts): this.
17165 2001-12-05 Akim Demaille <akim@epita.fr>
17167 * src/reduce.c (reduce_grammar_tables): No longer disable the
17168 removal of useless rules via CPP but via `if (0)', so that the
17169 compiler still check the code is valid.
17170 For instance, it should have noticed `rline' no longer exists: use
17171 the `line' member of rule_t.
17172 * src/gram.c (dummy, rline): Remove, unused.
17174 2001-12-05 Akim Demaille <akim@epita.fr>
17176 * src/output.c (pack_vector): Use assert, not berror.
17177 * src/main.c (berror): Remove, unused.
17179 2001-12-05 Akim Demaille <akim@epita.fr>
17181 New experimental feature: if --verbose --trace output all the
17182 items of a state, not only its kernel.
17184 * src/print.c (print_core): If `trace_flag', then invoke closure
17185 before outputting the items of the state (print_core is no longer
17186 a correct name them).
17187 (print_results): Invoke new_closure/free_closure if needed.
17189 2001-12-05 Akim Demaille <akim@epita.fr>
17191 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
17192 * src/closure.c, src/closure.h (itemsetsize): Rename as...
17193 (nitemset): for consistency with the rest of the project.
17195 2001-12-05 Akim Demaille <akim@epita.fr>
17197 * src/closure.c (print_closure): Improve.
17198 (closure): Use it for printing input and output.
17200 2001-12-05 Akim Demaille <akim@epita.fr>
17202 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
17203 indexed by nonterminals.
17205 2001-12-05 Akim Demaille <akim@epita.fr>
17207 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

17223 2001-12-05 Akim Demaille <akim@epita.fr>
17225 * src/output.c (action_row): De-obfuscate
17226 using the good o' techniques: arrays not pointers, variable
17227 locality, BITISSET, RESETBIT etc.
17229 2001-12-05 Akim Demaille <akim@epita.fr>
17231 Pessimize the code to simplify it: from now on, all the states
17232 have a valid SHIFTS, which NSHIFTS is possibly 0.
17234 * src/LR0.c (shifts_new): Be global and move to..
17235 * src/state.c, src/state.h: here.
17236 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
17237 * src/print_graph: Adjust.
17239 2001-12-05 Akim Demaille <akim@epita.fr>
17241 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
17242 * src/conflicts.c: Use it.
17243 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
17244 incorrectly ``simplified''.
17246 2001-12-05 Akim Demaille <akim@epita.fr>
17248 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
17249 using the good o' techniques: arrays not pointers, variable
17250 locality, BITISSET, RESETBIT etc.
17252 2001-12-05 Akim Demaille <akim@epita.fr>
17254 * src/state.h (SHIFT_SYMBOL): New.
17255 * src/conflicts.c: Use it to deobfuscate.

17259 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
17260 (print_reductions): De-obfuscate using the good o' techniques:
17261 arrays not pointers, variable locality, BITISSET.

17284 2001-12-05 Akim Demaille <akim@epita.fr>
17286 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
17287 * src/lalr.c: Use them.
17289 2001-12-05 Akim Demaille <akim@epita.fr>
17291 * src/LR0.c (augment_automaton): Formatting changes.
17292 Better variable locality.

17296 * src/lalr.c (matrix_print): New.
17297 (transpose): Use it.

17300 2001-12-05 Akim Demaille <akim@epita.fr>
17302 * src/lalr.c (maxrhs): Move to...
17303 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
17304 * src/lalr.c (build_relations): Adjust.
17306 2001-12-05 Akim Demaille <akim@epita.fr>
17308 * src/lalr.c (transpose): Free the memory allocated to the
17309 argument, as it is replaced by the results by the unique caller.
17310 (build_relations): Merely invoke transpose: it handles the memory
17312 Improve variable locality.
17313 Avoid variables used as mere abbreviations.
17314 (compute_lookaheads): Use arrays instead of pointers.
17316 2001-12-05 Akim Demaille <akim@epita.fr>
17318 * src/lalr.c (initialize_F): Improve variable locality.
17319 Avoid variables used as mere abbreviations.
17321 2001-12-05 Akim Demaille <akim@epita.fr>
17323 * src/derives.c (print_derives): Display the ruleno.
17324 * src/lalr.c (initialize_F, transpose): Better variable locality

17332 2001-12-05 Akim Demaille <akim@epita.fr>
17334 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
17335 the handling of squeue.
17336 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
17338 2001-12-05 Akim Demaille <akim@epita.fr>
17340 Because useless nonterminals are now kept alive (instead of being
17341 `destroyed'), we now sometimes examine them, and store information
17342 related to them. Hence we need to know their number, and adjust
17343 memory allocations.
17345 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
17347 * src/LR0.c (allocate_itemsets): The memory allocated to
17348 `symbol_count' was used for two different purpose: once to count
17349 the number of occurrences of each symbol, and later reassigned to
17350 `shift_symbol', containing the symbol that can be shifted from a
17352 Deobfuscate, i.e., allocate, use and free `symbol_count' here
17354 (new_itemsets): Allocate `shift_symbol' here.
17355 (allocate_itemsets): symbol_count includes useless nonterminals.
17356 Make room for them.
17357 (free_storage): Use `free', not `XFREE', for pointers that cannot
17360 2001-12-05 Akim Demaille <akim@epita.fr>
17362 * src/nullable.c (set_nullable): Deobfuscate the handling of
17364 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
17366 2001-12-05 Akim Demaille <akim@epita.fr>
17368 * src/gram.c, src/gram.h (ritem_print): New.
17369 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
17370 (This useless function was defined only to work around VMS linkers
17371 that can't handle compilation units with variables only).
17372 * src/reduce.c (dump_grammar): Use it to trace the construction of
17375 2001-12-04 Paul Eggert <eggert@twinsun.com>
17377 * src/bison.simple (union yyalloc): Change member names
17378 to be the same as the stack names.
17379 (yyparse): yyptr is now union yyalloc *, not char *.
17380 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
17381 and may generate better code on some machines.
17382 (yystpcpy): Use prototype if __STDC__ is defined, not just
17383 if __cplusplus is defined.
17385 2001-11-30 Akim Demaille <akim@epita.fr>
17387 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
17388 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
17389 Gettext doesn't compile cleanly, and dies with -Werror.
17390 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
17391 Include WARNING_CFLAGS here.
17392 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
17393 before being defined.
17395 2001-11-27 Paul Eggert <eggert@twinsun.com>
17397 * lib/quotearg.h (quotearg_n, quotearg_n_style):
17398 First arg is int, not unsigned.
17399 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
17400 (SIZE_MAX, UINT_MAX): New macros.
17401 (quotearg_n_options): Abort if N is negative.
17402 Avoid overflow check on hosts where size_t is 64 bits and int
17403 is 32 bits, as overflow is impossible there.
17404 Fix off-by-one typo that caused unnecessary reallocation.
17406 2001-11-29 Paul Eggert <eggert@twinsun.com>
17408 Name space cleanup in generated parser.
17410 * doc/bison.texinfo (Bison Parser): Discuss system headers
17411 and their effect on the user name space.
17413 * src/bison.simple:
17414 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
17415 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
17416 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
17418 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
17419 on user names when possible.
17421 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
17422 Simplify test for whather <alloca.h> exists.
17424 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
17426 (<stdio.h>): Include if YYDEBUG.
17428 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
17429 ! defined (yyoverflow) && ! defined (yymemcpy).
17431 (yymemcpy, yyparse): Rename local variables as needed so that
17432 they all begin with 'yy'.
17434 (yystrlen, yystpcpy): New functions.
17436 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
17439 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
17440 instead of relying on string.h functions. Use YYSTACK_ALLOC
17441 and YYSTACK_FREE instead of malloc and free.
17443 2001-11-30 Akim Demaille <akim@epita.fr>
17445 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
17446 before their first uses.
17447 (YYBISON, YYPURE): Move to the top of the output.
17449 2001-11-30 Akim Demaille <akim@epita.fr>
17451 * tests/reduce.at (Useless Nonterminals): Fix.
17453 2001-11-30 Akim Demaille <akim@epita.fr>
17455 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
17456 if body instead of `;' to pacify GCC's warnings.
17458 2001-11-30 Akim Demaille <akim@epita.fr>
17460 Instead of mapping the LHS of unused rules to -1, keep the LHS
17461 valid, but flag the rules as invalid.
17463 * src/gram.h (rule_t): `useful' is a new member.
17464 * src/print.c (print_grammar): Adjust.
17465 * src/derives.c (set_derives): Likewise.
17466 * src/reader.c (packgram, reduce_output): Likewise.
17467 * src/reduce.c (reduce_grammar_tables): Likewise.
17468 * tests/reduce.at (Underivable Rules, Useless Rules): New.
17470 2001-11-30 Akim Demaille <akim@epita.fr>
17472 * src/reduce.c (reduce_output): Formatting changes.
17473 * src/print.c (print_results, print_grammar): Likewise.
17474 * tests/regression.at (Rule Line Numbers)
17475 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
17477 2001-11-30 Akim Demaille <akim@epita.fr>
17479 * src/reduce.c (nonterminals_reduce): Instead of throwing away
17480 useless nonterminals, move them at the end of the symbol arrays.
17481 (reduce_output): Adjust.
17482 * tests/reduce.at (Useless Nonterminals): Adjust.
17484 2001-11-30 Akim Demaille <akim@epita.fr>
17486 * src/reduce.c: Various comment/formatting changes.
17487 (nonterminals_reduce): New, extracted from...
17488 (reduce_grammar_tables): here.
17489 (reduce_grammar): Call nonterminals_reduce.
17491 2001-11-29 Paul Eggert <eggert@twinsun.com>
17493 * src/bison.simple (YYSTACK_REALLOC): Remove.
17494 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
17495 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
17497 (union yyalloc): New type.
17498 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
17499 an arbitrary restriction on hosts where size_t is wider than int.
17501 (yyparse): Don't dump core if alloca or malloc fails; instead, report
17502 a parser stack overflow. Allocate just one block of memory for all
17503 three stacks, instead of allocating three blocks; this typically is
17504 faster and reduces fragmentation.
17506 Do not limit the number of items in the stack to a value that fits
17507 in 'int', as this is an arbitrary limit on hosts with 64-bit
17508 size_t and 32-bit int.
17510 2001-11-29 Marc Autret <autret_m@epita.fr>
17512 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
17513 of defining YYERROR_VERBOSE.

17523 2001-11-28 Marc Autret <autret_m@epita.fr>
17525 * src/output.h: And put its extern declaration here.
17526 * src/output.c (error_verbose): Define here.
17527 (prepare): Echo name modification.
17528 * src/getargs.h: Clean its extern declaration.
17529 * src/getargs.c (error_verbose_flag): Remove.
17530 (getargs): Remove case 'e'.

17558 2001-11-28 Akim Demaille <akim@epita.fr>
17560 * src/closure.c (closure): `b' and `ruleno' denote the same value:
17563 2001-11-28 Akim Demaille <akim@epita.fr>
17565 * src/closure.c (closure): Instead of looping over word in array
17566 then bits in words, loop over bits in array.
17568 2001-11-28 Akim Demaille <akim@epita.fr>
17570 * src/closure.c (closure): No longer optimize the special case
17571 where all the bits of `ruleset[r]' are set to 0, to make the code

19320 New, from fileutils 4.0.37.
19321 * configure.in: Require Autoconf 2.49c. I took some time before

19345 s/\bENDFILE\b/tok_eof/g;

19367 * src/files.c (open_files): Don't call `compute_base_names', don't

19372 introduces a guaranteed SEGV for semantic parsers.
19373 * doc/bison.texinfo: Document them.
19374 * tests/suite.at: Exercise these %options.

19445 * src/bison.hairy: Likewise.

19594 Use `obstack_save'.
19595 * src/main.c (main): Don't use `atexit' to register `done', since
19596 it no longer has to remove tmp files, just call `output_files'
19597 when there are no errors.
19599 2000-11-02 Akim Demaille <akim@epita.fr>

19671 called after `//' or `/*' was read.
19672 (copy_comment, copy_definition, parse_union_decl, copy_action)
19673 (copy_guard): Adjust.
19675 2000-10-16 Akim Demaille <akim@epita.fr>
19677 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

19701 2000-10-04 Akim Demaille <akim@epita.fr>
19703 When a literal string is used to define two different tokens,
19704 `bison -v' segfaults.
19705 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
19707 * tests/regression.m4: New file.
19708 Include the core of the sample provided by Piotr Gackiewicz.
19709 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
19712 2000-10-04 Akim Demaille <akim@epita.fr>
19714 * src/reader.c (parse_expect_decl): Keep `count' within the size
19718 2000-10-02 Paul Eggert <eggert@twinsun.com>

19726 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
19729 2000-10-02 Akim Demaille <akim@epita.fr>
19731 * src/derives.c, src/print.c, src/reduce.c: To ease the
19732 translation, move some `\n' out of the translated strings.
19734 2000-10-02 Akim Demaille <akim@epita.fr>
19736 The location tracking mechanism is precious for parse error
19737 messages. Nevertheless, it is enabled only when `@n' is used in
19738 the grammar, which is a different issue (you can use it in error
19739 message, but not in the grammar per se). Therefore, there should
19740 be another means to enable it.
19742 * src/getargs.c (getargs): Support `--locations'.
19743 (usage): Report it.
19744 * src/getargs.h (locationsflag): Export it.
19745 * src/lex.c (percent_table): Support `%locations'.
19746 * src/reader.c (yylsp_needed): Remove this variable, now replaced
19747 with `locationsflag'.
19748 * doc/bison.texinfo: Document `--locations' and `%locations'.
19750 * tests/calc.m4: Test it.
19752 For regularity of the names, replace each
19753 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
19754 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
19755 In addition replace each `flag' with `_flag'.
19757 2000-10-02 Akim Demaille <akim@epita.fr>
19759 Also test parse error messages, including with YYERROR_VERBOSE.
19761 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
19763 Use it to check the computations.
19764 Use it to check `nonassoc' is honored.
19765 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
19766 `--yyerror-verbose'.
19767 (_AT_CHECK_CALC): Adjust to this option.

19770 2000-10-02 Akim Demaille <akim@epita.fr>
19772 Test also `--verbose', `--defines' and `--name-prefix'. Testing
19773 the latter demonstrates a flaw in the handling of non debugging
19774 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
19775 was used in order to simplify:
19791 unfortunately this leads to a CPP conflict when
19792 `--name-prefix=foo' is used since it produces `#define yydebug
19795 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
19796 (YYDPRINTF): New macro.
19798 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
19800 Also test `--verbose', `--defines' and `--name-prefix'.

19804 Improve the readability of the produced parsers.
19806 * src/bison.s1: Formatting changes.
19807 Improve the comment related to the `$' mark.
19808 (yydefault): Don't fall through to `yyresume': `goto' there.
19809 * src/output.c (output_parser): When the `$' is met, skip the end
19811 New variable, `number_of_dollar_signs', to check there's exactly
19812 one `$' in the parser skeleton.
19814 2000-10-02 Akim Demaille <akim@epita.fr>
19816 * lib/xstrdup.c: New file, from the fileutils.
19817 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
19818 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
19819 instead of strlen + xmalloc + strcpy.
19820 * src/symtab.c (copys): Remove, use xstrdup instead.
19822 2000-10-02 Akim Demaille <akim@epita.fr>
19824 * src/gram.h (associativity): New enum type which replaces the
19825 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
19826 `right_assoc', `left_assoc' and `non_assoc'.
19827 Adjust all dependencies.
19828 * src/reader.c: Formatting changes.
19829 (LTYPESTR): Don't define it, use it as a literal in
19830 `reader_output_yylsp'.
19831 * src/symtab.h (symbol_class): New enum type which replaces the
19832 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
19833 `sunknown', `stoken and `snterm'.
19835 2000-10-02 Akim Demaille <akim@epita.fr>
19837 * src/getargs.c (fixed_outfiles): Rename as...
19838 (yaccflag): for consistency and accuracy.
19839 Adjust dependencies.
19841 2000-10-02 Akim Demaille <akim@epita.fr>
19843 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
19844 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
19845 difficult and introduced a lot of core dump. It turns out that
19846 Bison used an implementation of `xmalloc' based on `calloc', and
19847 at various places it does depend upon the initialization to 0. I
19848 have not tried to isolate the pertinent places, and all the former
19849 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
19850 someone should address this issue.
19852 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
19853 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

19863 * src/system.h: Include `assert.h'.
19865 2000-10-02 Akim Demaille <akim@epita.fr>
19867 * src/state.h (nstates, final_state, first_state, first_shift)
19868 (first_reduction): Move their exportation from here...

19870 Adjust dependencies.
19871 * src/getargs.c (statisticsflag): New variable.
19872 Add support for `--statistics'.

19879 * src/LR0.h: New file.
19882 2000-10-02 Akim Demaille <akim@epita.fr>

19909 Propagate its inclusion.
19910 * src/reduce.c: Topological sort and other formatting changes.
19911 (bool, TRUE, FALSE): Move their definition to...
19912 * src/system.h: here.
19914 2000-10-02 Akim Demaille <akim@epita.fr>
19916 * src/files.c: Formatting changes.
19917 (tryopen, tryclose, openfiles): Rename as...

19947 * src/output.c (token_actions): Introduce a temporary array,
19948 YYDEFACT, that makes it possible for this function to use
19949 output_short_table.
19951 2000-10-02 Akim Demaille <akim@epita.fr>
19953 `user_toknums' is output as a `short[]' in `output.c', while it is
19954 defined as a `int[]' in `reader.c'. For consistency with the
19955 other output tables, `user_toknums' is now defined as a table of

20220 Change the handling of @s so that they behave exactly like $s.
20221 There is now a pseudo variable @$ (readble and writable), location
20222 of the lhs of the rule (by default ranging from the location of
20223 the first symbol of the rhs, to the location of the last symbol,
20224 or, if the rhs is empty, YYLLOC).
20226 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
20228 (yyparse): When providing a default semantic action, provide a
20229 default location action.

20231 same way you stack YYVAL.
20232 * src/reader.c (read_declarations): Use warns.
20233 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

20258 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
20259 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
20260 One `#if YYDEBUG' remains, since it uses variables which are
20261 defined only if `YYDEBUG != 0'.
20263 2000-03-16 Akim Demaille <akim@epita.fr>
20265 * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

20932 * src/reader.c (reader_output_yylsp):
20934 (readgram): Use `#if 0' around code that accepted %command
20935 inside grammar rules: The documentation doesn't allow it,
20936 and it will fail since the %command processors scan for the next %.

20938 declaration to allow a multi-character symbol as an alias.
20939 (parse_thong_decl): New function.

20950 Revised and use multiple warnxxx functions to avoid using VARARGS1.
20951 (read_declarations): Improve the error message for
20952 an invalid character. Do not abort.
20953 (read_declarations, copy_guard, copy_action): Use
20954 printable_version to avoid unprintable characters in printed output.
20955 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
20956 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):

20979 (literalchar); new function to deal with reading \ escapes.
20980 (lex): Use literalchar.
20981 (lex): Implemented "..." tokens.
20982 (literalchar, lex, parse_percent_token): Made tokenbuffer
20983 always contain the token. This includes growing the token
20984 buffer while reading an integer.
20985 (parse_percent_token): Replaced if-else statement with percent_table.
20986 (parse_percent_token): Added % declarations as another
20987 way to specify the flags -n, -l, and -r. Also added hooks for
20988 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
20989 major changes to files.c.
20990 (lex) Retain in the incoming stream a character following
20992 (skip_white_space, lex): Revised most error messages
20993 and changed fatal to warn to avoid aborting.

20996 * src/gram.h: Comment changes.
20998 * src/files.c (openfiles, open_extra_files, done):
