389 Revert revision 178346 (2011-08-30)
390 which changed the prototype of check_qualified_type and related
391 functions so that their parameters were just 'tree' and not
392 'const_tree'. This seemed necessary at the time because of a
393 change to TYPE_BLOCK_FACTOR(), which in turn called function
394 that hashed the type node pointer. The hash functions did
395 not accept "const void *" pointers. Implement a work around
396 that removes this restriction.
397 * c/c-typeck.c: Revert.

1402 Re-implement the pass that lowers trees generated by
1403 the UPC front-end into GENERIC. Previously this was
1404 done within the gimplification framework, but this
1405 required that gimplification be run before inlining
1406 and various other passes, which did not fit in well
1407 with the current design of the middle-end passes.
1408 Now, the lowering is done by a newly defined language
1409 specific genericize hook. With this change, we are
1410 are able to undo some extensions made to the gimplify
1411 logic, and thus can revert several files to trunk.
1412 * c-decl.c: Add a check for UPC deprecated names which
1413 may appear as undefined function names.
1414 * libfuncs.h (LTI_upc_barrier, LTI_upc_notify, LTI_upc_wait,

1416 library function names. These were defined back when
1417 the libfunc interface was used to call these routines.

1419 in UPC lowering (genericize) pass.
1420 * langhooks.h (gimplify_expr): Revert to trunk's definition.

1424 * c-typeck.c (build_unary_op): Adjust reference to
1425 upc_genericize() in a comment.
1426 * gimplify.c (create_tmp_var_raw): Delete logic that
1427 was converting UPC shared types into unshared types
1428 to be used for temporaries. Now handled in upc_genericize().
1429 Replace with an assertion check.
1430 (prepare_gimple_addressable): Revert to trunk's definition.
1431 No longer needed as an externally called function.
1432 (flag_instrument_functions_exclude_p): Re-define as

1460 libcpp/
1461 * include/cpplib.h (enum c_lang):

1464 * init.c (lang_defaults): Add an entry for UPC.
1466 2011-06-09 Gary Funck <gary@intrepid.com>
1468 * c-parser.c (upc_localsizeof_type): Fix an ICE when compiling for
1469 a 32-bit target, the size expression overflowed, the result was
1470 error_mark_node, and an ICE was triggered on an attempt to evaluate
1471 C_TYPE_VARIABLE_SIZE() on the error node.
1472 (upc_blocksizeof_expr, upc_blocksizeof_type,
1473 upc_elemsizeof_expr, upc_elemsizeof_type, upc_localsizeof_expr):

1493 * configure.ac: Make the default order of the virtual
1494 address field in a UPC pointer-to-shared to be "first".
1495 This reverts to the previous setting, and is a short term
1496 measure to work around a bug found on the IA64,
1497 where vaddr=last led to incorrect code generation.
1498 Rename UPC_PTS_VADDR_FIRST to HAVE_UPC_PTS_VADDR_FIRST
1499 in AC_DEFINE(), to agree with recent changes in files

1834 Move UPC start files, end files, and linker specs.
1835 into libupc. This reduces the impact on common GCC
1836 configuration files, and ensures that these UPC-specific
1837 components are only built when the UPC language dialect is selected.
1838 * c-family/c.opt: Add -fupc-link switch, used to select UPC-specific
1839 linker specs. Fix typo in -fupc-debug message.
1840 * config/upc-conf.h, config/darwin.h: Move defines for
1841 UPC-related section begins/ends into libupc/config/default/
1842 upc-crt-config.h.

1844 UPC-related linker compiler specifications,
1845 accessed via %:include().
1846 * configure.ac, configure: Remove logic related to building
1847 upc-crtbegin/end. Remove config. tests for numa and cpu
1848 affinity (previously used by the 'upc' driver); these
1849 settings are now propagated by target-specific compiler
1850 specs. built by libupc. Regenerate autoconf.
1851 * gcc.c (LINK_COMMAND_SPEC): Add call outs to UPC-related
1852 linker compiler specifications, accessed via %:include().

1879 Diagnose an attempt to convert from an integer to
1880 a pointer-to-shared as an error. Also, fix various
1881 error messages so that they use the preferred term
1882 pointer-to-shared instead of "shared pointer".
1884 2011-02-07 Gary Funck <gary@intrepid.com>
1886 * c-typeck.c: (convert_for_assignment)

1904 2010-10-19 Gary Funck <gary@intrepid.com>
1906 * c-typeck.c: Fix typo in previous fix
1907 which led to a mis-compare for equal block sizes.
1909 2010-10-18 Gary Funck <gary@intrepid.com>
1911 * c-typeck.c: Fix bug: Cast of (shared <type> * shared) not
1912 diagnosed as an error
1913 The conversion from any type (shared or not) to
1914 a shared type is likely either meaningless or an error. This update
1915 makes any conversion to a shared type, an error.
1917 2010-10-18 Gary Funck <gary@intrepid.com>
1919 * c-typeck.c: Fix bug: passing int to shared pointer arg.
1920 generates spurious warning
1921 Add a #define procedure that does the same thing as
1922 WARN_FOR_ASSIGNMENT but issues an error diagnostic instead. Use
1923 this procedure to diagnose passing an integer value to a
1924 pointer-to-shared as an error.
1926 2010-10-18 Gary Funck <gary@intrepid.com>
1928 * c-typeck.c: Fix bug: shared [] in prototype silently ignored when
1929 matching routine declaration.
1930 When checking for type compatibility, shared qualified types must
1931 have the same block factor. This check was missing from
1932 comptypes_internal(). This update adds the check for blocking
1933 factor equality.
1935 2010-10-17 Gary Funck <gary@intrepid.com>
1937 * dwarf2out.c: Fix GCC Bug 45870 - note: non-delegitimized UNSPEC 5

1951 operations on generic pointer-to-shared as a compilation error.
1953 2010-10-17 Gary Funck <gary@intrepid.com>
1955 * c-decl.c: Fix a segfault/ICE that occurred when printing an error
1956 message regarding a function parameter being declared with a shared
1957 qualifier.
1958 The parameter's 'name' value is not defined at this point, and
1959 cannot be used in the error message. This update removes the
1960 reference to 'name', and eliminates the segfault.
1962 2010-10-16 Gary Funck <gary@intrepid.com>
1964 * Makefile.in: Implement fixes for SGI/IRIX/MIPS port.
1965 The gcc/Makefile.in rules for install-plugin had to be re-written to
1966 break up a long list of header files that exceeded the command line
1967 limitation imposed by Irix.
1968 Access functions for TFmode types had to be implemented.
1969 Apparently, this is the mode used for the SGI/MIPS port to represent
1970 "long float".
1972 2010-10-14 Gary Funck <gary@intrepid.com>
1974 * c-decl.c: Fix bug: Multiple equal blocking factors specified
1975 via typedef chain should not be diagnosed as an error.
1976 If the block size that is given by the typedef is equal to the block
1977 size given explicitly in the variable declaration, then do not
1978 complain. The easiest way to make this check was to create a
1979 temporary type that is a clone of the element type and then set its
1980 block size using the given layout qualifier. Then compare the block
1981 size of the temporary (the declaration) to the block size specified
1982 in the typedef. This complexity is needed, because the '[*]' block
1983 size needs to be calculated, and the '[]' needs to be mapped into a
1984 zero block size.
1986 2010-10-10 Gary Funck <gary@intrepid.com>
1988 * c-decl.c: Fix bug: ICE: two or more layout qualifiers
1989 specified
1990 The compiler properly detected the presence of two or more layout
1991 qualifiers as an error, but then hit an assertion check, because the
1992 code that followed the error expected to see a qualifier and not a
1993 layout specifier. The fix is simple: just return immediately after
1994 detecting the error.
1996 2010-10-10 Gary Funck <gary@intrepid.com>
1998 * c-decl.c: Improve error diagnostics for various cases of UPC
1999 shared array type declarations.
2000 Add the check for this error: "In the dynamic translation
2001 environment, THREADS may not appear in declarations of shared arrays
2002 with indefinite block size". Also, fix up a few of the other
2003 related error diagnostics.
2005 2010-10-09 Gary Funck <gary@intrepid.com>
2007 * c-common.c: Fix bug: segfault on incomplete array definition.
2008 This turned out to be a bit complicated. The logic in
2009 upc_lang_layout_decl had to be re-arranged to avoid trying to lookup
2010 the THREADS identifier in the case where the blocking factor has
2011 been set to indefinite ([]). This can happen when indefinite array
2012 declarations are processed for shared arrays. At that time, the
2013 file scope has been closed and THREADS is no longer in scope. Some
2014 more work is needed on upc_lang_layout_decl(). It has some
2015 duplication, and notably duplicates the two branches of the if
2016 having to do with TYPE_SIZE and TYPE_SIZE_UNIT, that appear in the
2017 caller of this routine (layout_decl()).
2018 The method of forcing a layout qualifier of [] in the indefinite
2019 declaration handler is odd a well. The code that just does the
2020 setting of the block factor, needs to moved into its own routine
2021 that doesn't depend upon a declspec for '[]' to be passed in, just
2022 in order to set the blocking factor to some value (in this case, 0).
2023 Also, the logic for how that shared type is constructed is strange.
2024 First the type with 0 blocking factor is set. Then the shared
2025 qualifier is removed from the type, and then added back later. The
2026 intermediate type has a blocking factor set, but it has no shared
2027 qualifier. Fixing this will require some thought. It is tempting
2028 just to make indefinite shared arrays an error, rather than forcing
2029 the dimension to be '1'.
2030 This likely fixes a serious error in the previous update to
2031 upc_lang_layout_decl(), where it didn't have the logic to set
2032 TYPE_SIZE_UNIT() in the main part of the 'if' statement. This means
2033 the previous update would fail on many tests.
2035 2010-10-09 Gary Funck <gary@intrepid.com>
2037 * varasm.c: Add an assertion check for the case that DECL_SIZE_UNIT
2038 (decl) is null, which can happen if some layout error occurred
2039 upstream.
2041 2010-10-09 Gary Funck <gary@intrepid.com>
2043 * c-decl.c: Fix bug: file scope shared arrays mis-diagnosed as
2044 "variable-sized" when compiled in dynamic threads.
2045 This long-standing bug is easily fixed. Just check
2046 for the situation that the non-constant sized type is shared and
2047 that it does not have a dimension that references a multiple of
2048 threads. If this criteria is met, then issue a meaningful
2049 diagnostic.
2051 2010-10-01 Gary Funck <gary@intrepid.com>
2053 * configure, configure.ac: Update manual page, and bug reporting
2054 URL. Update "man" page to reflect debugging switches.
2055 Also, some general clean up. Change the bug reporting
2056 URL to point to gccupc.org.
2058 2010-09-27 Gary Funck <gary@intrepid.com>
2060 * c-parser.c, config/upc-conf.h: Issue a descriptive message when
2061 the UPC forall depth count variable is not found.
2062 The __upc_forall_depth variable should be defined in gcc-upc-lib.h.
2063 The compiler will generate code that references this variable in
2064 order to implement nested upc_forall semantics. If there is a
2065 compiler build or install problem, this variable may not be found.
2066 In this case, terminate with an internal_error().
2068 2010-09-26 Gary Funck <gary@intrepid.com>
2070 * c-parser.c: Fix Bug 240: upc_forall with empty clauses
2071 mis-diagnosed as syntax error.
2072 Fix a failure exhibited by the Berkeley test case,
2073 bug873a.upc, which has the code:
2074 double d;
2075 upc_forall (;;;d) {...} The compiler did not properly handle
2076 the empty "condition" clause, and did not recover well when it was
2077 determined that the use of a double value, "d" above, was neither a
2078 pointer-to-shared nor an integer expression. The update implements a
2079 fix for both issues.

2082 2010-09-23 Gary Funck <gary@intrepid.com>
2084 * c-decl.c: Fix Bug 29: Layout qualifier within a typedef is not
2085 incorporated into the referencing type.
2086 This was semi-fixed a few times before. This update fixes a few
2087 more places where the layout qualifier wasn't being propagated
2088 through typedef's properly. What made this a bit tricky is shown in
2089 the example cited in the bug report:
2090 typedef shared [5] int A_t; A_t A[5*THREADS];
2091 In the typedef, the blocksize is being applied to a shared *scalar*,
2092 and the code was applying the blocksize only to arrays. This update
2093 handles shared scalars correctly.
2095 2010-09-22 Gary Funck <gary@intrepid.com>
2097 * c-parser.c, c-tree.h, stub-upc.c: Fix Bug 403: Nested
2098 upc_forall() semantics are not implemented
2099 The checkforall test in the Berkeley harness test suite indicated
2100 that GCC/UPC was not properly implementing nested upc_forall
2101 semantics. Nested upc_forall statements (both statically or
2102 dynamically nested) must implement their affinity clause as if it
2103 were "continue"; thus all steps in the loop must execute without
2104 regard for affinity. To implement these semantics a global depth
2105 counter, __upc_forall_depth, is maintained by the generated code
2106 that implements upc_forall.

2111 2010-09-19 Gary Funck <gary@intrepid.com>
2113 * c-decl.c: c-decl.c: zero out the layout specifier, after
2114 processing an array type.
2115 Fix the previous fix, that moved the setting of the type's layout
2116 qualifier to the outside of the array type processing loop. What is
2117 missing from the fix is that the layout_qualifier variable needs to
2118 be cleared after setting the type's blocksize.
2120 2010-09-19 Gary Funck <gary@intrepid.com>
2122 * config/upc-conf.h: Fix Bug 375: error message is off-by-one when
2123 given blocksize is greater than UPC_MAX_BLOCKSIZE.
2124 The value we were using for UPC_MAX_BLOCK_SIZE was one bigger than
2125 the actual maximum block size. Therefore, the message was correct,
2126 but the underlying value that was being checked was wrong. Change
2127 the values so that they agree with the actual implementation-defined
2128 limit.
2130 2010-09-11 Gary Funck <gary@intrepid.com>
2132 * c-decl.c: Fix Bug 402: ICE: '[*]' layout factor on
2133 multi-dimensional shared array with dynamic threads.
2134 This declaration caused an internal compiler error when compiled
2135 with dynamic threads:
2136 shared [*] int A[THREADS][16]; The bug was discovered when
2137 compiling the RTED_UPC test suite.
2138 The fix is to process layout qualifiers after the entire array type
2139 has been built. Otherwise, we try to calculate the blocksize on a
2140 shared array type that has not had its "size depends upon the value
2141 of THREADS" flag set.
2142 Also, added a test case.

2147 Fix a bug where a statement in c_build_qualified_type()
2148 in the trunk had been inadvertently deleted.
2149 This bug showed up in the IA64 port, because jmpbuf's
2150 on that architecture must be 16 byte aligned, and they were not.
2151 c-typeck.c (c_build_qualified_type): Revive the deleted line.
2153 2010-07-08 Gary Funck <gary@intrepid.com>
2155 Make changes so that other language compilers
2156 will build and bootstrap.
2157 * c-family/c-common.c (compiling_upc, flag_upc,

2165 It had been incorrectly spelled as Objc.
2166 * c-family/c.opt: Add UPC for the various switches
2167 that are valid for both C and ObjC.
2168 * c-fmaily/c-opts.c: Add CL_UPC to the list of
2169 supported options switches when compiling assembly
2170 language.
2171 * lto/lto-lang.c (use_upc_dwarf2_extensions,
2172 flag_upc_instrument, flag_upc_instrument_functions):

2175 * upc/ChangeLog: Move relevant entries
2176 to ChangeLog.upc.
2177 * c-family/stub-upc.c (compiling_upc, flag_upc,

2183 * objc/objc-act.c (objc_gimplify_expr): Add additional
2184 parameters to c_gimplify_expr() call, that are used

2193 * java/Make-lang.in (C_STUB_OBJS): Likewise.
2194 * objc/Make-lang.in: Link with c-family/stub-upc.o
2195 to avoid undefined references.
2196 c-parser.c: Fix line indentation.
2197 * libcpp/include/cpplib.h: Remove CL_UPC from
2198 the list of language kinds accepted by the
2199 C preprocessor. This is not necessary because
2200 UPC is a derivative of C99, and does not need
2201 a different language kind.
2202 * c-fmaily/c-opts.c (c_common_handle_option):
2203 Call set_std_c99() when processing the

2309 * tree.h (check_qualified_type): Change 'const_tree'
2310 argument types back to 'tree' to avoid complaints
2311 of assignment drops qualifiers for invocations of the
2312 newly implemented TYPE_BLOCK_FACTOR() macro, which
2313 invokes hash functions with 'tree' pointer values that

2365 (upc_grok_layout_qualifier, upc_lang_layout_decl, upc_pts_int_sum):
2366 Rename UPC_TYPE_HAS_THREADS_FACTOR() to TYPE_HAS_THREADS_FACTOR().

2415 * print_tree.c (print_node): Re-format a long line.
2417 2011-08-28 Gary Funck <gary@intrepid.com>
2419 Re-work the type machinery to fully support and to unify support
2420 for the UPC layout qualifier (blocking factor).
2421 * upc/upc-genericize.c (upc_simplify_shared_ref): Call
2422 c_build_qualified_type_1() instead of upc_set_block_factor()

2435 the block size of the element type into the result type, and checks
2436 for errors due to an attempt to merge differing blocking factors.

2601 Re-implement the pass that lowers trees generated by
2602 the UPC front-end into GENERIC. Previously this was
2603 done within the gimplification framework, but this
2604 required that gimplification be run before inlining
2605 and various other passes, which did not fit in well
2606 with the current design of the middle-end passes.
2607 Now, the lowering is done by a newly defined language
2608 specific genericize hook. With this change, we are
2609 are able to undo some extensions made to the gimplify
2610 logic, and thus can revert several files to trunk.
2611 * c-decl.c: Add a check for UPC deprecated names which
2612 may appear as undefined function names.
2613 * libfuncs.h (LTI_upc_barrier, LTI_upc_notify, LTI_upc_wait,
2614 LTI_upc_getaddr): Remove definitions of unused UPC
2615 library function names. These were defined back when
2616 the libfunc interface was used to call these routines.

2618 in UPC lowering (genericize) pass.
2619 * langhooks.h (gimplify_expr): Revert to trunk's definition.

2624 upc_genericize() in a comment.
2625 * gimplify.c (create_tmp_var_raw): Delete logic that
2626 was converting UPC shared types into unshared types
2627 to be used for temporaries. Now handled in upc_genericize().
2628 Replace with an assertion check.
2629 (prepare_gimple_addressable): Revert to trunk's definition.
2630 No longer needed as an externally called function.
2631 (flag_instrument_functions_exclude_p): Re-define as

2668 Re-implement the pass that lowers trees generated by
2669 the UPC front-end into GENERIC. Previously this was
2670 done within the gimplification framework, but this
2671 required that gimplification be run before inlining
2672 and various other passes, which did not fit in well
2673 with the current design of the middle-end passes.
2674 Now, the lowering is done by a newly defined language
2675 specific genericize hook. With this change, we are
2676 are able to undo some extensions made to the gimplify
2677 logic, and thus can revert several files to trunk.

2708 upc-pts-struct.c, upc-gasp.c, upc-pts-packed.c,
2709 upc-cmd.c, upc-act.c: Improve/add comments, fix
2710 typos and spelling errors.
2712 2011-06-13 Gary Funck <gary@intrepid.com>
2714 libcpp/
2715 * include/cpplib.h (enum c_lang):
2716 Move the entry for CLK_UPC so that it follows CLK_STDC1X.
2717 This keeps all the "C" variants together.
2718 * init.c (lang_defaults): Add an entry for UPC.
2720 2011-06-10 Gary Funck <gary@intrepid.com>
2722 * upc/upc-act.c (upc_set_block_factor): Handle the case where
2723 the UPC blocking factor expression overflowed.
2725 2011-06-09 Gary Funck <gary@intrepid.com>
2727 * c-parser.c (upc_localsizeof_type): Fix an ICE when compiling for
2728 a 32-bit target, the size expression overflowed, the result was
2729 error_mark_node, and an ICE was triggered on an attempt to evaluate
2730 C_TYPE_VARIABLE_SIZE() on the error node.
2731 (upc_blocksizeof_expr, upc_blocksizeof_type,
2732 upc_elemsizeof_expr, upc_elemsizeof_type, upc_localsizeof_expr):

2753 * upc/upc-lang.c (upc_check_decl_init): Use recently defined
2754 'append_to_statement_list_force' function to add UPC
2755 initialization statements to the UPC initialization
2756 statement list ('upc_init_stmt_list').
2757 (upc_build_init_func): Use recently defined
2758 'append_to_statement_list_force' function to add
2759 statements listed in 'upc_init_stmt_list' onto the
2760 function body constructed to implement initialization
2761 of UPC declarations that require active initialization
2762 at program start up. The previous methods of manipulating
2763 statement lists no longer worked, due to changes in the
2764 the statement list structure.
2766 2011-05-30 Gary Funck <gary@intrepid.com>
2768 * configure.ac: Make the default order of the virtual
2769 address field in a UPC pointer-to-shared to be "first".
2770 This reverts to the previous setting, and is a short term
2771 measure to work around a bug found on the IA64,
2772 where vaddr=last led to incorrect code generation.
2773 Rename UPC_PTS_VADDR_FIRST to HAVE_UPC_PTS_VADDR_FIRST
2774 in AC_DEFINE(), to agree with recent changes in files
2775 that reference this define.
2776 configure, config.in: Regenerate.

2787 * upc/upc-pts-struct.c: Revert to code that aligned the
2788 internal pointer-to-shared representation to
2789 twice the alignment of a pointer. This fixes
2790 an ICE that occurred when building the compiler
2791 on an IA64 target.
2793 2011-05-18 Gary Funck <gary@intrepid.com>
2795 Merge trunk version 173845 into gupc branch.

2821 types and objects.
2822 * c-parser.c (c_parser_upc_forall_statement): Remove
2823 reference to UPC_FORALL_DEPTH_NAME, and call

2826 moved to "upc/upc-rts-names.h", "defaults.h", and
2827 "upc/upc-pts.h".

3298 2011-03-21 Gary Funck <gary@intrepid.com>
3300 Merge trunk version 171202 into gupc branch.
3302 2011-03-20 Gary Funck <gary@intrepid.com>
3304 * varasm.c: Call error() directly with a format specifier,
3305 rather than using sprintf() to format the message.
3306 This should make it easier to internationalize UPC's error messages.
3308 2011-03-20 Gary Funck <gary@intrepid.com>
3310 * configure.ac: Fix the check for gnu ld when enabling
3311 UPC link script support.
3312 configure: Regenerate (also picks up changes from previous
3313 merge with trunk).
3315 2011-03-20 Gary Funck <gary@intrepid.com>
3317 Move UPC start files, end files, and linker specs.
3318 into libupc. This reduces the impact on common GCC
3319 configuration files, and ensures that these UPC-specific
3320 components are only built when the UPC language dialect is selected.
3321 * c-family/c.opt: Add -fupc-link switch, used to select UPC-specific
3322 linker specs. Fix typo in -fupc-debug message.
3323 * config/upc-conf.h, config/darwin.h: Move defines for
3324 UPC-related section begins/ends into libupc/config/default/
3325 upc-crt-config.h.
3326 * config/darwin.h(LINK_COMMAND_SPEC_A): Add call outs to
3327 UPC-related linker compiler specifications,
3328 accessed via %:include().
3329 * configure.ac, configure: Remove logic related to building
3330 upc-crtbegin/end. Remove config. tests for numa and cpu
3331 affinity (previously used by the 'upc' driver); these
3332 settings are now propagated by target-specific compiler
3333 specs. built by libupc. Regenerate autoconf.
3334 * gcc.c (LINK_COMMAND_SPEC): Add call outs to UPC-related
3335 linker compiler specifications, accessed via %:include().
3336 Define 'upc_crtbegin_spec', 'upc_crtend_spec', and
3337 'link_upc_spec'.
3338 * Makefile.in: Remove definition of UPC_CRTSTUFF_CFLAGS.
3339 * config/linux.h, config/i386/darwin.h, config/i386/linux64.h,
3340 config/i386/linux.h, config/i386/t-darwin, config/i386/t-darwin64,
3341 config/ia64/linux.h, config/mips/t-iris,
3342 config/mips/iris6.h: Revert to trunk version 167307.
3343 libgcc/
3344 * configure, configure.ac, config.host, Makefile.in:
3345 Revert to trunk version 167307.
3347 2011-03-20 Gary Funck <gary@intrepid.com>
3349 * upc/upc-act.c: Call error() directly with a format specifier,
3350 rather than using sprintf() to format the message.
3351 This should make it easier to internationalize UPC's error messages.
3353 2011-03-20 Gary Funck <gary@intrepid.com>
3355 Move UPC start files, end files, and linker specs.
3356 into libupc. This reduces the impact on common GCC
3357 configuration files, and ensures that these UPC-specific
3358 components are only built when the UPC language dialect is selected.
3359 * upc/config-lang.in: Remove setting of 'upc_extra_parts', which
3360 was used to specify which upc-crtbegin and upc-crtend files
3361 need to built. Remove extraneous (commented out)
3362 settings of 'cfiles'. The listed configuration files
3363 have been reverted to trunk, and weren't referenced
3364 via cfiles in any event.
3365 * upc/upc-cmd.c: Remove test for HAVE_UPC_LINK_SCRIPT.
3366 Simply test for the presence of the UPC link script
3367 in the current directory or the libupc directory.
3368 Add -B<path-to-libupc> to the switches passed to 'gcc';
3369 this is needed in order to find the upc-crtbegin
3370 and upc-crtend object files now built in libupc.
3371 Remove test for and inclusion of UPC_LINKER_SWITCHES.
3372 if extra switches are needed for a particular target
3373 (like SGI/Irix), they will be defined by the custom
3374 linker spec. built in libupc. Remove test for
3375 HAVE_UPC_NUMA_SUPPORT; if '-lnuma' is needed, it
3376 will be added to the custom linker specs. built
3377 in libupc.
3378 * upc/upc-crtstuff.c: Move to libupc.
3380 2011-02-23 Gary Funck <gary@intrepid.com>
3382 * c-decl.c (undeclared_variable): fix typo. Inadvertently
3383 removed negation on following 'if'.
3385 2011-02-22 Gary Funck <gary@intrepid.com>
3387 * c-decl.c (undeclared_variable): call upc_diagnose_deprecated_stmt
3388 to check for the usage of certain deprecated UPC keywords.
3389 * c-family/stub-upc.c (upc_diagnose_deprecated_stmt): New.
3390 * c-tree.h (undeclared_variable): Define prototype.
3392 2011-02-22 Gary Funck <gary@intrepid.com>
3394 * upc/upc-act.c (upc_diagnose_deprecated_stmt): New.
3395 upc-act.h (upc_diagnose_deprecated_stmt): Define.
3396 Check usage of deprecated keywords and issue
3397 error message.
3399 2011-02-12 Gary Funck <gary@intrepid.com>
3401 * c-typeck.c: (build_c_cast, convert_for_assignment)
3402 Diagnose an attempt to convert from an integer to
3403 a pointer-to-shared as an error. Also, fix various
3404 error messages so that they use the preferred term
3405 pointer-to-shared instead of "shared pointer".
3407 2011-02-08 Gary Funck <gary@intrepid.com>
3409 * upc/upc-pts-struct.c: Fix bug: (pts + int) fails when int is negative
3410 for struct-pts representation
3411 Analysis indicated that for something like (+ ptr -80) this was
3412 being represented as (+ ptr (- 80)) and further, when the
3413 calculations were propagated into the individual operations on the
3414 components of the 'struct' pointer, it would end up with something
3415 like (+ ptr.vaddr (- 80)), and the type of (- 80) would end up as
3416 "long unsigned int" because of the addition to the pointer. This
3417 caused the calculations involving the signed 'int' operand to be
3418 performed incorrectly. This fix insures that the 'int' operand is
3419 signed.
3421 2011-02-08 Gary Funck <gary@intrepid.com>
3423 * upc/config-lang.in, upc/lang-specs.h, upc/Makefile.in,
3424 upc/Make-lang.in, upc/upc.1, upc/upc-act.c, upc/upc-act.h,

3428 upc/upc-pts-struct.c, upc/upc-tree.def, upc/upc-tree.h:
3429 Update copyright notices.
3431 2011-02-07 Gary Funck <gary@intrepid.com>
3433 * c-typeck.c: (convert_for_assignment)
3434 Fix typo. in error message.
3436 2011-01-23 Gary Funck <gary@intrepid.com>
3438 * c-typeck.c: (c_build_qualified_type)
3439 derive UPC block size by calling upc_get_block_size(),
3440 to ensure that the element type of an array of an array
3441 is derived correctly.
3443 2011-01-09 Gary Funck <gary@intrepid.com>
3445 Fix behavior of upc_localsizeof() when called in a dynamic
3446 threads compilation environment. This bug, and the expected
3447 behavior is documented in this bug report:
3448 https://upc-bugs.lbl.gov/bugzilla/show_bug.cgi?id=2960.
3449 * upc/_act.c (upc_localsizeof): Re-implement.
3451 2010-12-29 Gary Funck <gary@intrepid.com>
3453 Merge trunk version 168314 into gupc branch.
3455 2010-12-15 Gary Funck <gary@intrepid.com>
3457 Merge trunk version 167307 into gupc branch.
3459 2010-12-15 Gary Funck <gary@intrepid.com>
3461 Merge trunk version 167307 into gupc branch.
3462 * upc/_act.h: (upc_handle_option) add location and struct
3463 cl_option_handlers * parameters.
3464 (upc_finish_file) Remove.
3465 (upc_write_global_declarations) New, replaces upc_finish_file.
3466 * lang-spec.h: Disable multi-file compilation for .upc files.
3467 This fixes an issue where file-scoped static variables were
3468 diagnosed as multiply-defined. Both "C" and "ObjC" also disable
3469 multi-file compilation.
3470 * upc/upc-gimplify.c: (upc_expand_put) Check for INDIRECT_REF_P()
3471 explicitly when deciding whether a UPC shared object is addressable.
3472 is_gimple_addressable() used to do this, but now checks for MEM_REF
3473 which does not apply to UPC shared objects.
3474 (upc_gimplify_lval, upc_gimplify_expr) Delete references to
3475 ALIGN_INDIRECT_REF and MISALIGNED_INDIRECT_REF.
3476 These are no longer defined.
3477 (upc_genericize) Add call to bitmap_obstack_initialize()
3478 and bitmap_obstack_release() around call to gimplify_function_tree().
3479 * upc/upc-lang.c: Add #include of "opts.h" and "options.h".
3480 (flag_upc_debug, flag_upc_inline_lib, flag_upc_instrument,
3481 flag_upc_instrument_functions) Remove. Use definitions
3482 generated by the options file.
3483 (upc_init_options) Use cl_decoded_option struct.
3484 (LANG_HOOKS_WRITE_GLOBALS) Define as upc_write_global_declarations.
3485 (finish_file) Delete.
3486 (upc_init_options) Call control_warning_option() to specify
3487 -Werror=pointer-arith as the default. Remove call to
3488 enable_warning_as_error().
3489 * upc/upc-pts-struct.c: (upc_pts_init_type) Move test that
3490 UPC_PTS_THREAD_SIZE is a multiple of a byte into an "if" statement
3491 rather than an #ifdef; this macro now depends upon a
3492 target size macro which must be evaluated at runtime.
3493 * upc/Make-lang.in: (cc1-dummy) Remove make target.
3494 (cc1upc-checksum.c) Generate directly from object files.
3495 * upc/upc-cmd.c: (SWITCH_TAKES_ARG, WORD_SWITCH_TAKES_ARG) Delete
3496 references to these deprecated macro definitions.
3497 (GCC_WORD_SWITCH_TAKES_ARG, GCC_WORD_SWITCH_TAKES_ARG) New.
3498 (all_exec_args) Delete variable.
3499 (exec_args) Re-define as (const char *).
3500 (exec_arg_list) New. Make copy of exec_args to pass to 'exec'.
3501 * upc/upc-act.c: (upc_handle_option) Update argument list to accept
3502 (cl_option_handlers *) argument.
3503 (upc_finish_file) Rename to upc_write_global_declarations.
3504 (upc_write_global_declarations) New.
3506 2010-10-19 Gary Funck <gary@intrepid.com>
3508 * c-typeck.c: Fix typo in previous fix
3509 which led to a mis-compare for equal block sizes.
3511 2010-10-18 Gary Funck <gary@intrepid.com>
3513 * c-typeck.c: Fix bug: Cast of (shared <type> * shared) not
3514 diagnosed as an error
3515 The conversion from any type (shared or not) to
3516 a shared type is likely either meaningless or an error. This update
3517 makes any conversion to a shared type, an error.
3519 2010-10-18 Gary Funck <gary@intrepid.com>
3521 * c-typeck.c: Fix bug: passing int to shared pointer arg.
3522 generates spurious warning
3523 Add a #define procedure that does the same thing as
3524 WARN_FOR_ASSIGNMENT but issues an error diagnostic instead. Use
3525 this procedure to diagnose passing an integer value to a
3526 pointer-to-shared as an error.
3528 2010-10-18 Gary Funck <gary@intrepid.com>
3530 * c-typeck.c: Fix bug: shared [] in prototype silently ignored when
3531 matching routine declaration.
3532 When checking for type compatibility, shared qualified types must
3533 have the same block factor. This check was missing from
3534 comptypes_internal(). This update adds the check for blocking
3535 factor equality.
3537 2010-10-17 Gary Funck <gary@intrepid.com>
3539 * dwarf2out.c: Fix GCC Bug 45870 - note: non-delegitimized UNSPEC 5
3540 found (-O1 -g)
3541 See: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45870#c6
3543 2010-10-17 Gary Funck <gary@intrepid.com>
3545 * tree-cfg.c: Implement the fix for GCC Bugzilla Bug
3546 45869 - [4.5/4.6 Regression] type mismatch in shift expression
3547 produces ice with -O3 and -m32.
3548 See: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45869
3550 2010-10-17 Gary Funck <gary@intrepid.com>
3552 * c-common.c: Diagnose the application of the various "*sizeof"
3553 operations on generic pointer-to-shared as a compilation error.
3555 2010-10-17 Gary Funck <gary@intrepid.com>
3557 * c-decl.c: Fix a segfault/ICE that occurred when printing an error
3558 message regarding a function parameter being declared with a shared
3559 qualifier.
3560 The parameter's 'name' value is not defined at this point, and
3561 cannot be used in the error message. This update removes the
3562 reference to 'name', and eliminates the segfault.
3564 2010-10-17 Gary Funck <gary@intrepid.com>
3566 * upc/upc-act.c: Issue a compilation error on attempts to perform
3567 arithmetic on generic pointer-to-shared values.
3568 (The rest of this update is a small code clean up.)
3570 2010-10-17 Gary Funck <gary@intrepid.com>
3572 * upc/upc-lang.c: For UPC only, issue errors for arithmetic and related
3573 operations on void types.
3574 This update simulates the effect of -Werror=pointer-arith, thus
3575 causing arithmetic on void types, sizeof(void) and so on to be
3576 considered compilation errors. This meets the expectations of some
3577 harness tests and the RTED/CTED test suites. GCC is more
3578 permissive, but since this is for UPC only, we can fairly safely
3579 define this new policy.
3581 2010-10-16 Gary Funck <gary@intrepid.com>
3583 * Makefile.in: Implement fixes for SGI/IRIX/MIPS port.
3584 The gcc/Makefile.in rules for install-plugin had to be re-written to
3585 break up a long list of header files that exceeded the command line
3586 limitation imposed by Irix.
3587 Access functions for TFmode types had to be implemented.
3588 Apparently, this is the mode used for the SGI/MIPS port to represent
3589 "long float".
3591 2010-10-16 Gary Funck <gary@intrepid.com>
3593 * upc/upc-act.c: Fix bug: Static initialization of shared
3594 arrays is unsupported -- issue an error message.
3595 Currently, static initialization of a shared array is not
3596 implemented correctly.
3597 We do not plan to fix this for a while, therefore the compiler will
3598 issue an error message indicating that this is an unsupported
3599 operation.
3601 2010-10-14 Gary Funck <gary@intrepid.com>
3603 * c-decl.c: Fix bug: Multiple equal blocking factors specified
3604 via typedef chain should not be diagnosed as an error.
3605 If the block size that is given by the typedef is equal to the block
3606 size given explicitly in the variable declaration, then do not
3607 complain. The easiest way to make this check was to create a
3608 temporary type that is a clone of the element type and then set its
3609 block size using the given layout qualifier. Then compare the block
3610 size of the temporary (the declaration) to the block size specified
3611 in the typedef. This complexity is needed, because the '[*]' block
3612 size needs to be calculated, and the '[]' needs to be mapped into a
3613 zero block size.
3615 2010-10-13 Gary Funck <gary@intrepid.com>
3617 * upc/upc-act.c: Fix bug: negative layout qualifiers not diagnosed
3618 as an error.
3619 The CTED_UPC test c_A_1_3_b.upc, specified a negative blocksize, but
3620 it was not diagnosed as an error. With this fix, negative block
3621 sizes will generate a translation error.
3623 2010-10-10 Gary Funck <gary@intrepid.com>
3625 * c-decl.c: Fix bug: ICE: two or more layout qualifiers
3626 specified
3627 The compiler properly detected the presence of two or more layout
3628 qualifiers as an error, but then hit an assertion check, because the
3629 code that followed the error expected to see a qualifier and not a
3630 layout specifier. The fix is simple: just return immediately after
3631 detecting the error.
3633 2010-10-10 Gary Funck <gary@intrepid.com>
3635 * c-decl.c: Improve error diagnostics for various cases of UPC
3636 shared array type declarations.
3637 Add the check for this error: "In the dynamic translation
3638 environment, THREADS may not appear in declarations of shared arrays
3639 with indefinite block size". Also, fix up a few of the other
3640 related error diagnostics.
3642 2010-10-10 Gary Funck <gary@intrepid.com>
3644 * upc/upc-act.c: Fix bug: ICE: Attempt to take the difference of
3645 shared and non-shared pointers
3646 The compiler detected the error, and then tried to return
3647 error_mark_node. This apparently is not acceptable, as there is an
3648 explicit assertion check to prevent this from happening in
3649 build_binary_op. Return the more user-friendly size_one_node
3650 instead.
3652 2010-10-09 Gary Funck <gary@intrepid.com>
3654 * c-common.c: Fix bug: segfault on incomplete array definition.
3655 This turned out to be a bit complicated. The logic in
3656 upc_lang_layout_decl had to be re-arranged to avoid trying to lookup
3657 the THREADS identifier in the case where the blocking factor has
3658 been set to indefinite ([]). This can happen when indefinite array
3659 declarations are processed for shared arrays. At that time, the
3660 file scope has been closed and THREADS is no longer in scope. Some
3661 more work is needed on upc_lang_layout_decl(). It has some
3662 duplication, and notably duplicates the two branches of the if
3663 having to do with TYPE_SIZE and TYPE_SIZE_UNIT, that appear in the
3664 caller of this routine (layout_decl()).
3665 The method of forcing a layout qualifier of [] in the indefinite
3666 declaration handler is odd a well. The code that just does the
3667 setting of the block factor, needs to moved into its own routine
3668 that doesn't depend upon a declspec for '[]' to be passed in, just
3669 in order to set the blocking factor to some value (in this case, 0).
3670 Also, the logic for how that shared type is constructed is strange.
3671 First the type with 0 blocking factor is set. Then the shared
3672 qualifier is removed from the type, and then added back later. The
3673 intermediate type has a blocking factor set, but it has no shared
3674 qualifier. Fixing this will require some thought. It is tempting
3675 just to make indefinite shared arrays an error, rather than forcing
3676 the dimension to be '1'.
3677 This likely fixes a serious error in the previous update to
3678 upc_lang_layout_decl(), where it didn't have the logic to set
3679 TYPE_SIZE_UNIT() in the main part of the 'if' statement. This means
3680 the previous update would fail on many tests.
3682 2010-10-09 Gary Funck <gary@intrepid.com>
3684 * varasm.c: Add an assertion check for the case that DECL_SIZE_UNIT
3685 (decl) is null, which can happen if some layout error occurred
3686 upstream.
3688 2010-10-09 Gary Funck <gary@intrepid.com>
3690 * c-decl.c: Fix bug: file scope shared arrays mis-diagnosed as
3691 "variable-sized" when compiled in dynamic threads.
3692 This long-standing bug is easily fixed. Just check
3693 for the situation that the non-constant sized type is shared and
3694 that it does not have a dimension that references a multiple of
3695 threads. If this criteria is met, then issue a meaningful
3696 diagnostic.
3698 2010-10-09 Gary Funck <gary@intrepid.com>
3700 * upc/upc-act.c: Fix bug: segfault on incomplete array definition.
3701 This turned out to be a bit complicated. The logic in
3702 upc_lang_layout_decl had to be re-arranged to avoid trying to lookup
3703 the THREADS identifier in the case where the blocking factor has
3704 been set to indefinite ([]). This can happen when indefinite array
3705 declarations are processed for shared arrays. At that time, the
3706 file scope has been closed and THREADS is no longer in scope. Some
3707 more work is needed on upc_lang_layout_decl(). It has some
3708 duplication, and notably duplicates the two branches of the if
3709 having to do with TYPE_SIZE and TYPE_SIZE_UNIT, that appear in the
3710 caller of this routine (layout_decl()).
3711 The method of forcing a layout qualifier of [] in the indefinite
3712 declaration handler is odd a well. The code that just does the
3713 setting of the block factor, needs to moved into its own routine
3714 that doesn't depend upon a declspec for '[]' to be passed in, just
3715 in order to set the blocking factor to some value (in this case, 0).
3716 Also, the logic for how that shared type is constructed is strange.
3717 First the type with 0 blocking factor is set. Then the shared
3718 qualifier is removed from the type, and then added back later. The
3719 intermediate type has a blocking factor set, but it has no shared
3720 qualifier. Fixing this will require some thought. It is tempting
3721 just to make indefinite shared arrays an error, rather than forcing
3722 the dimension to be '1'.
3723 This likely fixes a serious error in the previous update to
3724 upc_lang_layout_decl(), where it didn't have the logic to set
3725 TYPE_SIZE_UNIT() in the main part of the 'if' statement. This means
3726 the previous update would fail on many tests.

3747 * upc/upc-act.c: Do not zap all qualifier bits when constructing a
3748 non-shared result node.
3749 This fix was suggested by Paul H. in the following Berkeley Bugzilla
3750 report: https://upc-bugs.lbl.gov/bugzilla/show_bug.cgi?id=2061 The
3751 use of "!" rather than "~" zapped all the type qualifier bits rather
3752 than just those that are related to the "shared" qualifier. This
3753 fix clears only the relevant bits.

3757 * c-parser.c, config/upc-conf.h: Issue a descriptive message when
3758 the UPC forall depth count variable is not found.
3759 The __upc_forall_depth variable should be defined in gcc-upc-lib.h.
3760 The compiler will generate code that references this variable in
3761 order to implement nested upc_forall semantics. If there is a
3762 compiler build or install problem, this variable may not be found.
3763 In this case, terminate with an internal_error().

3767 * c-parser.c: Fix Bug 240: upc_forall with empty clauses
3768 mis-diagnosed as syntax error.
3769 Fix a failure exhibited by the Berkeley test case,
3770 bug873a.upc, which has the code:
3771 double d;
3772 upc_forall (;;;d) {...} The compiler did not properly handle
3773 the empty "condition" clause, and did not recover well when it was
3774 determined that the use of a double value, "d" above, was neither a
3775 pointer-to-shared nor an integer expression. The update implements a
3776 fix for both issues.

3781 * upc/upc-act.c: Fix bug: upc_forall with empty clauses
3782 mis-diagnosed as syntax error.
3783 A failure was exhibited by the Berkeley test case,
3784 bug873a.upc, which has the code:
3785 double d;
3786 upc_forall (;;;d) {...} The compiler did not properly handle
3787 the empty "condition" clause, and did not recover well when it was
3788 determined that the use of a double value, "d" above, was neither a
3789 pointer-to-shared nor an integer expression. The update implements a
3790 fix for both issues.

3795 * upc/upc-pts-struct.c: Fix an ICE on 32-bit/struct target: failed
3796 gimple check when calculating affinity for upc_forall.
3797 Intrepid test, test10.upc, failed to compile due a mis-match between
3798 the COMPONENT_REF node and the internal 'thread' field. Changed the
3799 code to make the types agree, and added a conversion to sizetype if
3800 necessary.
3802 2010-09-23 Gary Funck <gary@intrepid.com>
3804 * c-decl.c: Fix Bug 29: Layout qualifier within a typedef is not
3805 incorporated into the referencing type.
3806 This was semi-fixed a few times before. This update fixes a few
3807 more places where the layout qualifier wasn't being propagated
3808 through typedef's properly. What made this a bit tricky is shown in
3809 the example cited in the bug report:
3810 typedef shared [5] int A_t; A_t A[5*THREADS];
3811 In the typedef, the blocksize is being applied to a shared *scalar*,
3812 and the code was applying the blocksize only to arrays. This update
3813 handles shared scalars correctly.
3815 2010-09-23 Gary Funck <gary@intrepid.com>
3817 * upc/upc-act.c: Fix bug: ICE: '[*]' layout factor applied to array
3818 with static threads and size not a multiple of threads.
3819 Add an extra check for an attempt to apply a '[*]' layout qualifier
3820 to a shared array that does not specify a size that is a multiple of
3821 THREADS, when compiled in a static THREADS compilation environment.
3823 2010-09-22 Gary Funck <gary@intrepid.com>
3825 * c-parser.c, c-tree.h, stub-upc.c: Fix Bug 403: Nested
3826 upc_forall() semantics are not implemented
3827 The checkforall test in the Berkeley harness test suite indicated
3828 that GCC/UPC was not properly implementing nested upc_forall
3829 semantics. Nested upc_forall statements (both statically or
3830 dynamically nested) must implement their affinity clause as if it
3831 were "continue"; thus all steps in the loop must execute without
3832 regard for affinity. To implement these semantics a global depth
3833 counter, __upc_forall_depth, is maintained by the generated code
3834 that implements upc_forall.

3841 * upc/upc-act.c, upc/upc-act.h: Fix bug: Nested upc_forall() semantics
3842 are not implemented
3843 The checkforall test in the Berkeley harness test suite indicated
3844 that GCC/UPC was not properly implementing nested upc_forall
3845 semantics. Nested upc_forall statements (both statically or
3846 dynamically nested) must implement their affinity clause as if it
3847 were "continue"; thus all steps in the loop must execute without
3848 regard for affinity. To implement these semantics a global depth
3849 counter, __upc_forall_depth, is maintained by the generated code
3850 that implements upc_forall.

3857 * c-decl.c: c-decl.c: zero out the layout specifier, after
3858 processing an array type.
3859 Fix the previous fix, that moved the setting of the type's layout
3860 qualifier to the outside of the array type processing loop. What is
3861 missing from the fix is that the layout_qualifier variable needs to
3862 be cleared after setting the type's blocksize.
3864 2010-09-19 Gary Funck <gary@intrepid.com>
3866 * config/upc-conf.h: Fix Bug 375: error message is off-by-one when
3867 given blocksize is greater than UPC_MAX_BLOCKSIZE.
3868 The value we were using for UPC_MAX_BLOCK_SIZE was one bigger than
3869 the actual maximum block size. Therefore, the message was correct,
3870 but the underlying value that was being checked was wrong. Change
3871 the values so that they agree with the actual implementation-defined
3872 limit.
3874 2010-09-18 Gary Funck <gary@intrepid.com>
3876 * upc/upc-act.c, upc/upc-pts-packed.c, upc/upc-pts-struct.c:
3877 Implement -fupc-debug switch.
3879 2010-09-11 Gary Funck <gary@intrepid.com>
3881 * c-decl.c: Fix Bug 402: ICE: '[*]' layout factor on
3882 multi-dimensional shared array with dynamic threads.
3883 This declaration caused an internal compiler error when compiled
3884 with dynamic threads:
3885 shared [*] int A[THREADS][16]; The bug was discovered when
3886 compiling the RTED_UPC test suite.
3887 The fix is to process layout qualifiers after the entire array type
3888 has been built. Otherwise, we try to calculate the blocksize on a
3889 shared array type that has not had its "size depends upon the value
3890 of THREADS" flag set.
3891 Also, added a test case.

3896 Fix a bug where a statement in c_build_qualified_type()
3897 in the trunk had been inadvertently deleted.
3898 This bug showed up in the IA64 port, because jmpbuf's
3899 on that architecture must be 16 byte aligned, and they were not.
3900 c-typeck.c (c_build_qualified_type): Revive the deleted line.
3902 2010-07-08 Gary Funck <gary@intrepid.com>
3904 Make changes so that other language compilers
3905 will build and bootstrap.
3906 * c-family/c-common.c (compiling_upc, flag_upc,
3907 flag_upc_instrument, flag_upc_instrument_functions,
3908 use_upc_dwarf2_extensions): Move to stub-upc.c and
3909 upc-lang.c.
3910 * c-family/c-common.h (use_upc_dwarf2_extensions,
3911 compiling_upc): Add extern definitions - needed
3912 to compile/build other language front ends.
3913 * c-family/c.opt: Fix the spelling of ObjC.
3914 It had been incorrectly spelled as Objc.
3915 * c-family/c.opt: Add UPC for the various switches
3916 that are valid for both C and ObjC.
3917 * c-fmaily/c-opts.c: Add CL_UPC to the list of
3918 supported options switches when compiling assembly
3919 language.
3920 * lto/lto-lang.c (use_upc_dwarf2_extensions,
3921 flag_upc_instrument, flag_upc_instrument_functions):
3922 Remove these definitions. They have been moved
3923 to c-family/stub-upc.c.
3924 * upc/ChangeLog: Move relevant entries
3925 to ChangeLog.upc.
3926 * c-family/stub-upc.c (compiling_upc, flag_upc,
3927 flag_upc_instrument, flag_upc_instrument_functions,
3928 use_upc_dwarf2_extensions): Moved from c-common.c
3929 * upc/upc-lang.c (compiling_upc, flag_upc,
3930 flag_upc_instrument, flag_upc_instrument_functions,
3931 use_upc_dwarf2_extensions): Moved from c-common.c
3932 * objc/objc-act.c (objc_gimplify_expr): Add additional
3933 parameters to c_gimplify_expr() call, that are used
3934 by upc's tree rewrites.
3935 * cp/cp-gimplify.c (cp_gimplify_expr): Likewise.
3936 * gcc/cp/lex.c (init_reswords): If not compiling
3937 UPC, then mask off the UPC keywords.
3938 * cp/Make-lang.in (C_STUB_OBJS): Use this
3939 make macro to link with c-family/stub-objc.o
3940 and c-family/stub-upc.o.
3941 * fortran/Make-lang.in (C_STUB_OBJS): Likewise.
3942 * java/Make-lang.in (C_STUB_OBJS): Likewise.
3943 * objc/Make-lang.in: Link with c-family/stub-upc.o
3944 to avoid undefined references.
3945 c-parser.c: Fix line indentation.
3946 * libcpp/include/cpplib.h: Remove CL_UPC from
3947 the list of language kinds accepted by the
3948 C preprocessor. This is not necessary because
3949 UPC is a derivative of C99, and does not need
3950 a different language kind.
3951 * c-fmaily/c-opts.c (c_common_handle_option):
3952 Call set_std_c99() when processing the
3953 "--lang upc" switch, instead of setting the
3954 language kind to CL_UPC.
3955 * libupc/testsuite/libupc.upc/intrepid/ChangeLog: New.
3957 2010-07-03 Gary Funck <gary@intrepid.com>

3962 Add 'unused' attributes to avoid "set, but
3963 not referenced" warnings.
3964 * libupc/testsuite/libupc.upc/intrepid/test18.upc:
