2882 Thu Oct 27 12:50:24 1994 Per Bothner <bothner@kalessin.cygnus.com>
2884 * expr.c (build_chill_repetition_op): Fix repeating all-zero
2885 bitstring with orig_len!=1. Also, call build_boring_bitstring
2886 if original string was all ones, using one range. Also:
2887 Cannot use one-bit TYPE_PRECISION to get bitstring length.
2889 Tue Oct 25 14:11:07 1994 Per Bothner <bothner@kalessin.cygnus.com>
2891 * convert.c (convert): When converting BOOL constant to
2892 bit-string, bit_one_node and bit_zero_node were switched.
2893 * actions.c (chill_expand_assignment): Use force_addr_of,
2894 not build_chill_addr_expr - latter yields bogus error.
2896 Fri Oct 21 14:26:52 1994 Per Bothner <bothner@kalessin.cygnus.com>
2898 * expr.c (build_chill_indirect_ref): Check for POINTER_TYPE (only)
2899 after converting from REFERENCE_TYPE.
2900 * expr.c (build_compare_expr): Convert to common mode *after*
2901 we've checked compatibility.
2903 Fri Oct 21 02:29:15 1994 Wilfried Moser (moser@rtl.cygnus.com)
2905 * lex.l (check_newline): Use getc instead of getlc to read
2906 the filename in a # line name directive to avoid possibly
2907 downcaseing of a filename.

2924 of NUM. NUM delivers the INT derived class.
2926 * grant.c (write_spec_module): Add writing of
2927 <> USE_SEIZE_FILE "x.grt" <>
2928 SEIZE ALL;

2938 * convert.c (convert): Only call digest_array_tuple if ARRAY_TYPE.
2939 * typeck.c (chill_expand_tuple): Print error if type is
2940 neither array, struct, or powerset.
2942 * expr.c (chill_expand_expr cases CONCAT_EXPR, SET_*_EXPR,
2943 UNDEFINED_EXPR): Call preserve_temp_slots for temp targets.
2944 If target is not MEM, make temp (even if not REG) to simplify
2945 - and don't copy original target to temp target first. (Not needed.)
2947 * lang.c (maybe_objc_comptypes): Just return -1.

2977 * expr.c (build_chill_descr): Add missing call to mark_addressable.
2978 * loop.c (toop_loop_end_check): Replace build1 (ADDR_EXPR ...)
2979 with call to force_addr_of (which calls mark_addressable).
2980 * expr.c (build_chill_descr, build_chill_inttime): Likewise.
2981 * inout.c (build_chill_writetext): Likewise.
2983 Mon Sep 26 05:19:21 1994 Wilfried Moser (moser@rtl.cygnus.com)

3086 * lex.l (readstring): Add processing of control sequence
3087 in character string literals. The granting mechanism writes
3088 this to grant files.

3092 * expr.c (compare_records): In case of -fpack do always
3093 a memcmp instead of comparing each field of the

3107 the entrypoint of a process.
3108 (build_process_header): Change PROCESS arguments to be
3109 like arguments of a function. There will be a wrapper
3110 which is the real entry point for a PROCESS. This wrapper
3111 is automatically build after a PROCESS definition and gets
3112 as argument a pointer to a structure looking like the
3113 arguments of the PROCESS. This wrapper will call the
3114 PROCESS (see build_process_wrapper).
3115 (build_process_wrapper): New function (see above).
3116 (build_start_process): Change processing of arguments.
3117 (tasking_setup): Add processing of a different entry point

3129 * decl.c (init_decl_processing): Add declaration of memcmp
3130 function.
3132 * ch-tree.h: Add new prototype for build_process_wrapper,
3133 change prototypes for add_taskstuff_to_list and

3145 generated.
3146 * Makefile.in (GNUCHILL_VERSION): Remove it, its defined in
3147 Make-lang.in.
3149 * chill.in: In case of -fgrant-only pass "-S -o /dev/null"
3150 to the compiler to avoid generation of an object file.
3152 Thu Sep 8 12:07:28 1994 Per Bothner (bothner@kalessin.cygnus.com)
3154 * convert.c (display_int_cst), ch-tree.h: New function.
3155 * convert.c (digest_array_tuple): Use digest_int_cst to
3156 provide better error messages. Return error_mark_node on error.
3157 * grant.c (decode_const): Simplify by using digest_int_cst.
3158 * grant.c (format_character, find_assoc): Removed.
3160 * decl.c (do_decl): Add missing TREE_CHAIN.
3162 * decl.c (finish_incomplete_decl): Removed.

3164 (finish_decl): Remove old C-specific code to deduce size of
3165 array from initialization.
3166 (complete_array_type): Just make it abort.
3168 * except.c (finish_handler_array): Avoid calling C-specific kludge
3169 complete_array_type.
3171 * convert.c (digest_constructor): Rename, and re-write to:
3172 (digest_array_tuple, convert): No longer use the code in
3173 ../c-typeck.c; use a Chill-only implementation (sigh).
3175 * typeck.c (chill_expand_tuple): Remove unneeded call to
3176 complete_array_type.
3178 * expr.c (fold_set_expr), grant.c (decode_constant),
3179 typeck.c (expand_constant_to_buffer): Update name of called
3180 function unpack_set_constructor to get_set_constructor_bits.
3181 * expr.c (powersetlen ): Remove redundant call to convert.
3183 * ch-tree.h (unpack_set_constructor): Removed obsolete declaration.
3185 * inout.c (build_chill_writetext): Handle 64-bit integer literals
3186 by trying to convert them to a smaller type.
3188 * lex.l (convert_number): Always use long long type (possibly
3189 unsigned) to avoid problems with constant folding truncation.

3193 * ch-tree.h (enum chill_built_in_function): Add BUILT_IN_QUEUE_LENGTH.

3199 * tasking.c (build_queue_length): New function.
3201 * tasking.c (tasking_init): Add new external function definition.
3203 Thu Sep 1 15:38:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3205 * lex.l (default_lex): New function. Progress towards
3206 getting rid of [f]lex.
3208 * lex.l (convert_number): Use mul_double and add_double.
3209 Set result type to a reasonable type in which the literal
3210 will fit. Give error message if literal is too big.
3212 * lex.l (equal_number): Switch (temporarily) to permanent obstack.
3214 * typeck.c (build_chill_slice_with_range): Check for empty
3215 slice *after* we have checked for upper/lower limit in range.

3218 CHAR ranges are represented as INTEGER_TYPEs.)
3220 * tasking.c (build_process_header): Add missing call to
3221 expand_start_bindings.
3222 * parse.c (end_function): Add missing expand_end_bindings.
3224 Wed Aug 31 17:25:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3226 * decl.c (init_decl_processing): Set set_alignment.
3228 Tue Aug 30 16:40:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
3230 * actions.c (print_missing_cases, check_missing_cases,
3231 BITARRAY_TEST, BITARRAY_SET): New functions and macros,
3232 to check for completeness of case actions and expressions.
3233 * decl.c (c_decode_option, init_decl_processing):
3234 Don't set warn_switch.
3235 * expr.c (chill_expand_case_expr): Call check_missing_cases
3236 instead of check_for_full_enumeration_handling.
3237 * parse.c (parse_case_actions): Call check_missing_cases.
3239 * expr.c (build_chill_binary_op): Remove some dead code.
3240 * expr.c (chill_truthvalue_conversion): Call build_chill_binary_op

3258 * tasking.c (build_receive_signal_case_label): Remove backwards
3259 chill_convert_for_assignment (which converted whatever garbage
3260 was in the *target* to the type of the signal argument!).
3262 Fri Aug 19 07:10:43 1994 Wilfried Moser (moser@rtl.cygnus.com)
3264 * inout.c (build_chill_io_list_type, build_enum_tables),
3265 tasking.c (build_tasking_struct): Temporarily reset
3266 maximum_field_alignment to 0, so that the compiler-built
3267 data structures needed by the RTS can be independent of -fpack.
3269 Thu Aug 18 13:39:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3271 * typeck.c (build_init_struct): Temporarily reset
3272 maximum_field_alignment to 0, so that the compiler-built
3273 data structures needed by the RTS can be independent of -fpack.
3275 Wed Aug 17 23:48:33 1994 Wilfried Moser (moser@rtl.cygnus.com)
3277 * parse.c (parse_primval, expect, parse_on_exception_list):
3278 Print error message only in pass 2.

3287 bit-string, just generate a SLICE_EXPR.
3288 * decl.c (init_decl_processing): Declare __pscpy.
3289 * actions.c (chill_expand_assignment): Handle a SLICE_EXPR
3290 on the LHS of assignment, by calling __pscpy.
3291 * expr.c (chill_expand_expr): Handle SLICE_EXPR (as a RHS
3292 value) by using __psslice to copy slice to a temp.
3294 Wed Aug 17 05:52:44 1994 Wilfried Moser (moser@rtl.cygnus.com)
3296 * Make-lang.in: Change version of GNUCHILL compiler to 1.4.1.
3297 * expr.c (build_chill_length): Enable LENGTH built-in to process
3298 Buffers and Events too (Z.200/1992).
3299 * lex.l (yywrap): Always set yyin to finput and/or grt_in. On
3300 a linux system the previous version was not able to run.
3301 * tasking.c: Correct processing of infinite buffer- and event-length
3302 to avoid RANGEFAIL warning.
3304 Thu Aug 11 11:46:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3306 * parse.c (parse_if_expression_body): Don't call the C-specific
3307 build_conditional_expr. Just do build_nt (COND_EXPR, ...).
3308 * convert.c (convert): Convert a COND_EXPR by converting
3309 each branch.
3311 * convert.c (convert): Don't call convert before
3312 convert_to_reference. It's apt to do weird and unneedful things.
3313 * convert.c (convert): If the expression is varying, just call
3314 varying_to_slice, which simplifies quite a bit.
3316 * ch-tree.h (varying_to_slice): Add prototype.
3317 * typeck.c (varying_to_slice): Remove prototype.
3319 * satisfy.c (satisfy): Move case PAREN_EXPR from type 'e'
3320 to type '1'.
3322 * except.c (emit_setup_handler): Temporarily reset the
3323 maximum_field_alignment to zero so the compiler's exception
3324 data structures can be compatible with the run-time system,
3325 even when we're compiling with -fpack.
3327 * expr.c (compare_records): Call saved_if_needed on operands.
3329 * expr.c (build_set_expr case NE_EXPR): Don't use __nepowerset
3330 which has been reimplemented to just call __eqpowerset and
3331 invert the result. Inline this new implementation by
3332 handling as EQ_EXPR, and inverting the result.
3333 * decl.c (init_decl_processing): Don't define unused __eqpowerset.
3335 * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
3336 type boolean_type_node, not void_type_node. (Fixing this
3337 avoids a crash in the back-end.)
3339 * grant.c (decode_constant): In a CALL_EXPR, if the argument
3340 list is not a TREE_LIST (as in string repetiation), don't
3341 emit parentheses.
3343 Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3345 * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
3346 CONST_DECL is from a SET definition. (This is safer than
3347 checking that the type is ENUMERAL_TYPE, because synonym
3348 definitions may have a NULL TREE_TYPE.)
3349 Also, if we have duplicate enums whose types are identical,
3350 this is an error.
3351 * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
3352 an extra 'quiet' parameter, which is true if we're called from
3353 bind_sub_modules. (In that case an error message about duplicated
3354 decls would be repeated later, so suppress it.)
3356 * parse.c (stmt_count): Removed, not used.
3357 (INIT_ACTION): Call emit_line_note only if !ignoring.
3358 (parse_begin_end_block): Do INIT_ACTION even if ignoring.
3360 Fri Aug 5 12:39:11 1994 Per Bothner (bothner@kalessin.cygnus.com)
3362 * parse.c (parse_untyped_expr): Add missing semi-colon.
3364 Thu Aug 4 17:40:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
3366 * parse.c (parse_untyped_expr): Fix various problem for the
3367 case that we see a '(': Add missing 'case' keyword.
3368 Only recurse if '(' is followed by 'if', 'case' or '[',
3369 and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
3371 * parse.c (parse_send_action): Remove extra nreverse.
3373 Thu Jul 28 04:00:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3375 * expr.c (build_allocate_global_memory_call, build_allocate_memory_call):
3376 Add new checks.
3378 Tue Jul 26 22:48:15 1994 Michael Tiemann (tiemann@blues.cygnus.com)
3380 * parse.c (parse_untyped_expr): Added missing "case" before LPRN.
3381 Added a missing call to `require' as well.
3383 Tue Jul 19 10:30:12 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3385 * lex.l (yywrap): Define as yywrap_chill to avoid conflicts with
3386 the extern declaration in the flex skeleton.
3388 Mon Jul 18 23:06:04 1994 Per Bothner (bothner@kalessin.cygnus.com)
3390 * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
3391 Check the type of the instance expr using CH_COMPATIBLE,
3392 and not just == instance_type_node. (This allows
3393 the expression to have mode READ INSTANCE).
3394 * tasking.c (build_instance_type): Give instance_type_node
3395 a non-null novelty (i.e. different from a struct).
3396 * tasking.c (build_receive_case_start, build_delay_case_start):
3397 Check that for a location using CH_LOCATION_P.
3399 Mon Jul 18 13:22:23 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
3401 * expr.c (finish_chill_unary_op): Use TREE_SET_CODE not TREE_CODE
3402 to modify a tree code.
3404 Mon Jul 18 11:24:57 1994 Bill Cox (bill@rtl.cygnus.com)
3406 * convert.c (digest_structure_tuple): Fix thinko in TREE_CODE
3407 comparison.
3409 Mon Jul 18 05:40:15 1994 Doug Evans (dje@canuck.cygnus.com)
3411 * decl.c (warn_bad_function_cast): Define so cc1chill will link.
3413 Thu Jul 14 18:37:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3415 * parse.c (parse_send_action): Do tree_cons *before* checking
3416 for end of loop.
3418 Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3420 * convert.c (digest_structure_tuple): Don't use convert to
3421 coerce initial value, use chill_convert_for_assignment instead.
3422 (Thus we also get range_checking.)
3424 * expr.c (build_chill_card): Use force_addr_of instead of
3425 build_chill_addr_expr.
3427 * loop.c (build_temporary_variable): Stylistic tweak.
3428 * loop.c (maybe_make_for_temp): Initialize temp using
3429 explicitly, not using assignment. Avoids a problem if
3430 the expression is read-only.
3431 * typeck.c (smash_dummy_type): Always used the saved TYPE_NAME
3432 and CH_NOVELTY_FLAG.
3434 Wed Jul 6 20:12:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3436 * expr.c, ch-tree.h (finish_chill_unary_op): New function,
3437 based on code ripped out of build_chill_unary_op.
3438 (build_chill_unary_op): Call finish_chill_unary_op unless pass==1.
3439 * satisfy.c (satisfy): Call finish_chill_unary_op when needed.
3441 Mon Jun 27 11:29:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3443 * tree.c (save_if_needed), ch-tree.h: New function.
3444 * typeck.c (build_chill_slice_with_range,
3445 build_chill_slice_with_length): Call save_if_neeed on array arg.
3446 * expr.c (varying_to_slice): Re-write to use save_if_needed.
3448 * typeck.c (extract_constant_from_buffer): Handle BOOLEAN_TYPE.
3450 Mon Jun 27 01:11:10 1994 Wilfried Moser (moser@rtl.cygnus.com)
3452 * inout.c (build_chill_io_list_type): Change layout of __tmp_WIO_list
3453 that it is always the same, regardless if compiled with -fpack
3454 or not.
3456 Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3458 * lex.l (yywrap): Kludge to work around mis-synchronization
3459 between lexer (which read ahead) and parser: Don't emit
3460 (left-over) uze_seizefile directives at the end of file.
3462 * typeck.c (build_chill_array_ref): Allow the derived
3463 array indexing syntax for arrays of bit strings.
3464 Add a comment explaining why.
3466 * typeck.c, ch-tree.h (string_assignment_condition): Change
3467 the interface. Return a boolean expression (which can be
3468 used in a conditional at run-time); never expand anything.
3470 * actions.c (chill_convert_for_assignment): Check
3471 string_assignment_condition here, rather than in callers.
3472 * actions.c (chill_expand_assignment): Don't need to check
3473 string_assignment_condition here.
3474 * expr.c (build_chill_function_call): Likewise.
3475 * satisfy.c (safe_satisfy_decl): Update accordingly.
3476 * decl.c (do_decl): Simplify testing and conversion by
3477 deferring everything to chill_convert_for_assignment.
3479 * parse.c: Combine the two variables 'ignore_exprs' and
3480 'ignore_actions' into one variable called 'ignoring'.
3481 * ch-tree.h: Add 'extern int ignoring'.
3482 * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
3483 Rename ignore_actions and ignore_exprs to ignoring.
3484 Remove unneeded extern declarations.
3485 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3486 build_chill_arrow_expr, build_generalized_call, build_delay_action,
3487 build_buffer_type, build_event_type): I changed my mind. It is
3488 cleaner to check for 'ignoring' in the parser, rather than here.
3489 * parse.c (parse_action, parse_primval, parse_opt_mode):
3490 Therefore we must check for ignoring here.
3491 * parse.c (parse_loc_declaration): Set ignoring in pass 2
3492 when parsing the mode.
3494 * tasking.c (generate_tasking_code_variable): Do arithmetic
3495 on signal_code etc using unsigned rather than signed shorts.
3497 * grant.c (static char* current_grant_modename): Removed.
3498 * grant.c (decode_decl case CONST_DECL): Remove error message.
3500 * Make-lang.in (CHILL_SRCS): Add $(srcdir)/ch/parse.c.
3501 * Makefile.in: Fix dependencies for parse.o.
3502 Remove some duplicate dependencies for $(TREE_H).
3504 Mon Jun 13 14:25:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3506 * typeck.c (build_chill_cast): Allow a value cast between
3507 non-discrete object of the same size, but with a pedwarn.
3508 * typeck.c (bit_string_assignment_condition,
3509 char_string_assignment_condition): Merge near-duplicate functions
3510 and place the code in string_assignment_condition.
3512 * decl.c (parm_flag, declare_parm_level, in_param_level_p):
3513 Removed. Not used.
3514 * decl.c (start_chill_function, finish_chill_function): Make
3515 parameter level have same nesting level as body, as required by Z200.
3516 * decl.c (switch_to_pass_2): Always exit if an error has been found.
3517 * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
3518 generated from GRANT ALL.
3519 * decl.c (lookup_name_for_seizing): Don't seize from
3520 the nesting level of builtins (predefined objects).
3521 * decl.c (lookup_name_for_seizing): Make more robust on error.
3523 * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
3524 be 'RESULT' (or 'result'). This makes it more accessible from gdb.
3525 Also, use do_decl to declare it, so that debugging symbols are
3526 generated. And, re-arrange so that actions that need to
3527 be done both passes (such as push_levels) use the same code.
3529 * parse.c (get_type_of): If ignore_exprs, don't lookup name.
3530 * parse.c (end_function): Fix poplevel params.
3531 * parse.c (expect): Don't read forwards on an error.
3532 * parse.c (parse_field): Don't define two tag_list locals!
3533 * parse.c (parse_pass_1_2): Better error message.
3535 * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
3536 parse_opt_mode, rather than vice versa. If parse_opt_mode
3537 returns NULL_EXPR, then parse_mode gives an error.
3538 Change parse_opt_mode (and any functions it calls) to only
3539 return NULL_TREE if there is no mode (even on ignore_exprs).
3540 (parse_set_mode, parse_structure_mode, parse_procedure_mode):
3541 Never return NULL_EXPR.
3542 * tasking.c (build_buffer_type, build_event_type): Return
3543 void_type_node instead of NULL_EXPR if ignore_exprs is true.
3545 * parse.c (parse_synonym_definition): Call parse_untyped_expr
3546 only if we have a mode.
3547 * parse.c (parse_send_action): Parse list of untyped_expr's,
3548 rather than a list of (typed) expressions.
3549 * parse.c (parse_primval): Emit error if '[' seen without
3550 preceding mode name. (If this is to be allowed, call
3551 parse_untyped_expr instead.)
3553 * parse.c (parse_array_index): Renamed to ...
3554 (parse_index_mode): ... to match Z200 terminology.
3555 Re-write to resolve some of the nastier ambiguities,
3556 and allow things like ' CHAR(10) : CHAR(20) '.
3558 * parse.c (parse_tuple_element): Change interface to return
3559 reversed list, so don't call nreverse.
3560 * parse.c (parse_tuple): No longer nreverse element list here.
3561 * parse.c (parse_opt_element_list): Do nreverse here instead.
3562 * parse.c (parse_case_label_list): Call nreverse at end.
3564 Fri Jun 10 15:36:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
3566 * typeck.c (chill_similar): Remove bogus "else".
3568 Wed Jun 8 00:01:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
3570 * ch-tree.h (TYPE_ARRAY_MAX_SIZE): New macro (and comment)
3571 to make it clearer that we are using TYPE_MAX_VALUE in a special way.
3572 * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
3573 * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
3574 * convert.c (convert): When converting a fixed string/array
3575 to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
3576 of (the type of) the padding.
3577 * convert.c (convert): If the concatenation is non-constant, use
3578 the low-level 'build' to set the type of the result (which is usually
3579 a fixed-size array) rather than depend on build_chill_binary_op
3580 to figure it out (it's unable to simplify the size to a constant).
3582 Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
3584 * lang.c (lang_decode_option): Let -fspecial_UC imply
3585 -fno-ignore-case without requiring it explicitly.
3586 * lang.c (lang_decode_option): Support (experimentally)
3587 the -fpack and -fno-pack flags.
3589 Thu Jun 2 20:49:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3591 * configure: Add support for --program-prefix and --program-suffix.
3593 Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3595 * convert.c (digest_constructor): Check that initial value
3596 is compatible with element mode before calling convert.
3597 * typeck.c (chill_compatible): A string mode is not compatible
3598 with an untyped constructor.
3599 * decl.c (do_decl): Clean up error messages. Use error_with_decl.
3601 * ch-tree.h: Fix inconsistencies: bool_true_node ->
3602 boolean_true_node, and bool_false_node -> boolean_false_node.
3603 * typeck.c (valid_array_index_): Minor simplification.
3605 Tue May 31 04:33:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3607 * inout.c (build_chill_writetext): Add correct processing
3608 of POWERSET RANGE (setmode).
3610 * lex.l (same_file): Add searching for file(s) in
3611 seize_path_list.
3613 Fri May 27 14:22:42 1994 Per Bothner (bothner@kalessin.cygnus.com)
3615 * Make-lang.c (CHILL.mostlyclean, CHILL.distdir): Don't list
3616 yacc/bison output files, since the grammer is no longer in yacc.
3617 * config-lang.in (diff_excludes): Likewise.
3619 Thu May 26 16:38:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3621 * gperf, hash.h, lex.l, parse.h: Rename PROCESS_TYPE token
3622 (in some files spelled PROCESS_TYPE_ to avoid clashes
3623 with the PROCESS_TYPE tree_code) to PROCESS_TYPE_TOKEN.
3625 Thu May 26 02:18:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3627 * timing.c (build_cycle_start): Change call to __define_timeout.
3628 * decl.c (init_decl_processing): Change definitions of
3629 __define_timeout and __wait_timeout.
3631 Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
3633 Replace yacc-based parser with a recursive-decent parser.
3634 (This may seem backwards, but Chill [like C++] is not a
3635 language that is remotely LALR(1). Using a R-D parser
3636 allows us to use look-ahead and to back-up to resolve the
3637 difficult ambiguities.)
3638 * parse.y: Removed.
3639 * parse.c, parse.h: New files, containing new r-d parser.
3640 * Makefile.in: Update accordingly.
3641 * actions.c (chill_convert_for_assignment): Don't return
3642 NULL_EXPR if ignore_exprs is true. It simplifies the parser
3643 if we consistently reserve NULL_EXPR for a missing expression.
3644 * expr.c (build_chill_function_call): Likewise.
3646 * lex.l: Tweaks for new parser.
3647 * lex.l (prepare_paren_colon, paren_paren_colon_level,
3648 paren_level): Ugly hack no longer needed.
3650 * expr.c (build_chill_function_call): Cleanup.
3651 Call chill_convert_for_assignment to convert IN/INOUT
3652 paramaters on both input and output. For LOC parameters,
3653 give error if actual is a non-referable location.
3654 * actions.c (convert_for_assignment): Add new parameter (a
3655 "place" string used in error messages).
3656 * actions.c (adjust_parm_or_field): Removed.
3657 * actions.c (chill_expand_assignment): Take just a single LHS,
3658 and move support for multiple assignments to ...
3659 (expand_assignment_action): ... here. Some cleaning up.
3660 * timing.c (build_cycle_start): Adjust accordingly.
3661 * actions.c (expand_assignment_to_varying_array): Likewise.
3662 * tasking.c (many places): Ditto.
3663 * ch-tree.h: Fix declarations appropriately.
3665 * parse.c (parse_defining_occurrence_list): Return a single
3666 IDENTIFIER_NODE (instead of a singleton list) in the common
3667 case. Minor complication to save a minor amount of space.
3668 * decl.c (do_based_decls): Move guts of code into ...
3669 (do_based_decl): ... this new function.
3670 * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
3671 * decl.c (push_syndecl): Replace by ...
3672 (push_syndecl): ... (which only supports a single name).
3673 (push_modedef): Only handle a single name.
3674 * tasking.c (build_process_header, build_signal_struct_type):
3675 Adjust accordingly.
3677 * expr.c (build_generalized_call): Handle string repetition.
3678 * expr.c (build_chill_repetition_op): Change interface.
3679 * grant.c (decode_constant): Allow parameter list to be
3680 a non-TREE_LIST. (Used for string repetition.)
3682 Wed May 25 11:28:48 1994 Per Bothner (bothner@kalessin.cygnus.com)
3684 * lex.l (make_identifier): Replaced by ...
3685 (read_identifier, handle_name): ... new functions.
3686 * lex.l: Parse an identifiers using read_identifier using
3687 read_identifier and handle_name, rather than having [f]lex
3688 do it. (One reason is that lex uses a fixed-size buffer.)
3690 * lex.l (read_directive, skip_directive): New functions.
3691 Use them to parse compiler-directives, instead of rather
3692 ugly and useless use of lexer start conditions.
3694 Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3696 * decl.c (unnamed_module_number): Renamed to ...
3697 (module_number): .. and make non-static.
3698 (push_module): Always increment module_number.
3699 * lex.l (yywrap): Print warning if no modules seen.
3701 * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
3702 decl to current_seizefile_name (which is unreliable).
3703 * grant.c (chill_grant): Set it here instead.
3705 * expr.c (fold_set_expr): Use int_size_in_bytes instead of
3706 TYPE_PRECISION (which is not defined for a SET_TYPE).
3708 Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
3710 Cleanup to remove need for variables in common storage.
3711 * decl.c: Remove unused use of current_obstack.
3712 * actions.c (maybe_chill_check_decl): Remove unused function.
3713 * actions.h, lang.c: Remove uses of doing_chill_thang.
3714 * ch-tree.h (void_list_node): Make extern (rather than common).
3715 * decl.c (void_list_node): Add definition.
3717 Thu May 19 06:54:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
3719 * configure (build): Build canon_host and canon_target
3720 to pass it to all subsequently generated Makefiles (needed
3721 for testsuite/execute in case of cross build).
3723 Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
3725 * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
3726 the input type, which loses with the no-longer-new 2-pass
3727 implementation, since the input "type" could be an IDENTIFIER_NODE.
3728 * grant.c (raw_decode_mode): Rename to decode_mode.
3730 Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3732 * typeck.c (chill_location): Neither a STRING_CST nor a
3733 CONSTRUCTOR is a location.
3734 * typeck.c (chill_root_mode): Convert a function to a
3735 pointer-to-function.
3736 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3737 build_chill_arrow_expr): If ignore_exprs, return operand
3738 rather than NULL_EXPR. This makes it easier for the parser to
3739 distinguish missing expressions.
3740 * expr.c (build_max_min): Convert the lower bound of a
3741 set to a long before calling run-time routine.
3742 * expr.c (build_chill_pred_or_succ): Use discrete_type_p
3743 to check the argument type.
3744 * expr.c (build_chill_arrow_expr): If argument is not a location,
3745 do a predwarn if it is a STRING_CST or has function type.
3747 Tue May 17 06:05:13 1994 Wilfried Moser (moser@rtl.cygnus.com)
3749 * configure (build): Remove building of canon_host and canon_target.
3750 It doesn't work in any case.
3752 Mon May 16 02:10:35 1994 Wilfried Moser (moser@rtl.cygnus.com)
3754 * configure (build): Build canon_host and canon_target
3755 to pass it to all subsequently generated Makefiles (needed
3756 for testsuite/execute in case of cross build).
3757 * Make-lang.in (chill-runtime): Change chill to CHILL in the case
3758 statement to build chill-runtime automatically.
3760 Mon May 9 15:30:08 1994 Doug Evans (dje@canuck.cygnus.com)
3762 * Makefile.in (FLAGS_TO_PASS): Define.
3763 (OBJDEPS): Define.
3764 (../cc1chill): Depend on $(OBJDEPS) $(C_OBJS).
3765 * Make-lang.in (cc1chill): Delete dependency on $(OBJS) $(BC_OBJS).
3766 (CHILL.mostlyclean): Use `mostlyclean' as recursive target.
3768 Sun May 8 13:05:00 1994 Per Bothner (bothner@cygnus.com)
3770 * Make-lang.in (cc1chill): Should not depend on libgcc.a.
3772 Thu May 5 18:58:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
3774 * decl.c (copy_lang_decl): New (dummy) function.
3776 Mon May 2 14:33:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
3778 * parse.y (sendaction): Fix thinko (in sense of condition).
3779 * tasking.c (build_receive_case_label): Another thinko.
3781 * parse.y (optsigdest): Force ignore_exprs to 0 while parsing
3782 the (signal-)name.
3784 * decl.c (build_chill_function_type): Don't call layout_type
3785 (since that may prevent parameter or result types being
3786 properly satisfied).
3787 * satisfy.c (satisfy): Layout FUNCTION_TYPEs.
3788 * parse.y (procmode): Call build_chill_pointer_type, rather
3789 than build_pointer_type (which incorrectly sets TYPE_SIZE).
3791 * parse.y (get_type_of): Handle TYPE_DECL (again).
3792 * parse.y (optresultspec): Call build_chill_reference_type, rather
3793 than build_reference_type (which incorrectly sets TYPE_SIZE).
3794 * parse.y (range_or_mode): Rename to plain range, since it
3795 no longer matches modename.
3796 * actions.c (chill_handle_case_label_range): New function, with
3797 functionality moved out of chill_handle_case_label.
3798 * actions.c (chill_handle_case_label): Handle here the case that
3799 the label_value is a TYPE_DECL (modename). Also clean up some.
3800 * typeck.c (build_chill_slice_with_length): Convert max_index
3801 to the type of min_value. (Old code broke on varying strings.)

3812 * lex.h, lex.c: Remove lastiddecl.
3813 * lex.l (name_type_signal): Simplify. We no longer check for

3840 * parse.y (ioindexmode): Removed; use index_mode instead.
3841 * expr.c (build_generalized_call): If args is a RANGE_EXPR,
3842 we have either a slice or a range mode, depending on func.

3844 or a range mode.
3845 * parse.y (call): A slice with both end points can be a range
3846 mode, so defer handling to build_generalized_call (or index_mode).
3848 * typeck.c (build_chill_slice_with_length): Fix type-checking.
3849 * typeck.c (chill_novelty): Undo (part of) change of April 28:
3850 The novelty of a range mode is the novlety of the parent.
3851 * typeck.c (chill_root_mode): Don't return integer_type_node
3852 if argument has non-nil novelty.
3854 * decl.c (global_bindings_p): Return -1 as true, for the sake

3857 Fri Apr 29 13:42:43 1994 Per Bothner (bothner@kalessin.cygnus.com)
3859 * parse.y: Remove TYPENAME and modename. These are now plain
3860 NAMEs. Modify parsing actions appropriately.
3861 * expr.c (build_generalized_call): Handle the case that
3862 TREE_CODE (func) == TYPE_DECL (as in a cast).
3863 * lex.l (name_type_signal): Never return TYPENAME.

3913 * typeck.c (smash_dummy_type): Handle the special case of a
3914 NEWMODE of a range mode, as required by Z200, by creating a
3915 new parent mode with the new novelty (and casting the min
3916 and max of the range to teh new parent mode).

4255 string assignment case.
4256 * expr.c (chill_expand_expr): Now that we're using build_chill_function_call,

4267 * satisfy.c (safe_satisfy_decl): Add range-check for a SYN's value.
4269 Mon Mar 21 13:29:23 1994 Per Bothner (bothner@kalessin.cygnus.com)
4271 * typeck.c (layout_chill_range_type): Instead of tree_int_cst_lt
4272 use compare_int_csts (which is more robust when signedness differs).
4273 Also, convert the bounds *after* doing range checking.
4275 * ch-tree.def (SET_IN_EXPR): New.
4276 * expr.c (chill_expand_expr): Code to expand SET_IN_EXPR,
4277 moved from expand_expr in ../expr.c. Also add some extra

4300 Generate a compile-time message if possible.
4301 (build_compare_expr): Comment out compatibility test - should
4302 not be needed in here. Fix a couple of typos. Add some types
4303 to some build calls.
4305 Sun Mar 20 11:48:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
4307 * decl.c (init_decl_processing): Clean up parameter type
4308 list for __setbitpowerset,
4310 * typeck.c (chill_compatible_classes): Allow the M-reference
4311 to be compatible with the N-value class, with suitable M and N.
4312 * typeck.c (build_chill_slice): Don't smash a void TREE_TYPE.
4313 (We don't need to, and it causes confusion.)
4315 * expr.c (build_compare_expr): Fix thinko. Add save_exprs.
4317 * expr.c (build_compare_expr): Fix a transcription bug
4318 (for converting NULL INSTANCEs). Also #include convert.h.

4321 Works even if their types have different TREE_UNSIGNED.
4322 * expr.c (finish_chill_binary_op): Moved code dealing with
4323 the comparison operators from here ...
4324 * expr.c (build_compare_expr): ... to new function here.
4325 Also, for discrete types, tries to Do The Right Thing, even for
4326 differing values of TYPE_PRECISION and TREE_UNSIGNED.
4327 the code from lay
4328 * ch-tree.h: Declare new functions.
4329 * typeck.c (valid_array_index_p): Various cleanups,
4330 including using new build_parse_expr.
4331 * parse.y: Use new build_compare_expr.
4333 * inout.c (build_chill_writetext): Handle REFERENCE_TYPE args.
4335 Sun Mar 20 08:54:27 1994 Bill Cox (bill@rtl.cygnus.com)

4338 Call build_chill_array_ref to get index checking.
4339 (chill_convert_for_assignment): Delete unused errstr
4340 variable.
4341 (chill_expand_assignment): Call build_chill_array_ref
4342 to get runtime index checking.

4349 to have consistent operand types.
4350 * typeck.c (valid_array_index_p): Change interface to pass
4351 validity conditions back on caller's TREE_LIST. We
4352 cannot link the conditions to anything which a
4353 layout_type routine will expand, since that will occur
4354 before the exception handler is set up.
4355 Change calls to valid_array_index_p also.
4357 Fri Mar 18 14:40:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
4359 * actions.c, except.c, loop.c, tasking.c: Call
4360 build_chill_function_call instead of the C-specific
4361 build_function_call.

4363 * loop.c (top_loop_end_check): Coerce library function arg.
4364 * convert.c, expr.c: Re-write to avoid calls to C-specific
4365 function build_unary_op (e.g. by calling build1 directly).
4367 * typeck.c (chill_equivalent): Change to force failure
4368 for non-matching integral types (even if not ranges).
4370 * typeck.c, ch-tree.h (build_chill_slice): Make non-static.
4371 * expr.c (varying_to_slice): Call build_chill_slice (and not
4372 build_chill_slice_with_length, which does bunches of range
4373 checking and does not allow the length to be zero).
4374 * convert.c (convert): Fix off-by-one error.
4375 * actions.c (chill_expand_array_assignment): Minor cleaning up.
4377 Fri Mar 18 00:12:48 1994 Per Bothner (bothner@deneb.cygnus.com)
4379 * decl.c (init_decl_processing): __lepowerset and __ltpowerset
4380 take *two* pointer parameters, not one.
4381 * satisfy.c (satisfy): Only call the appropriate layout routine
4382 if TYPE_SIZE is 0 (i.e. type hasn't already been laid out).
4383 * typeck.c (build_chill_slice_with_length): Fix Bill's previous fix.
4385 Thu Mar 17 17:29:43 1994 Bill Cox (bill@rtl.cygnus.com)
4387 * expr.c (build_chill_function_call): Give function call the correct
4388 type tree.
4389 * typeck.c (build_chill_slice_with_length): Restore dynamic range
4390 checking, so it doesn't obscure the CONSTANTness of the length.
4392 Wed Mar 16 17:23:31 1994 Per Bothner (bothner@kalessin.cygnus.com)
4394 * typeck.c (build_chill_slice), expr.c (chill_expand_expr
4395 [case CONCAT_EXPR]): Remove kludge setting slice size upper bound
4396 in TYPE_LANG_SPECIFIC, and restore kludge setting it in MAX_VALUE.
4397 * typeck.c (build_chill_slice): Use TYPE_MAX_VALUE of
4398 array_type if needed for size upper bound of slice_type.
4399 * expr.c (build_concat_expr): Improve calculation of size upper bound.
4401 * typeck.c (valid_array_index_p): Check compatibility using
4402 correct types.
4403 * typeck.c (build_chill_slice_with_length); For now revert
4404 calling valid_array_index_p on length. (It makes it harder
4405 to realize when the slice is constant length.)
4406 * expr.c (build_chill_indirect_expr): Minor tweak. (This
4407 seems to work around a weird C compiler bug. ??)
4409 * expr.c (build_chill_function_call): Cleanup so it doesn't
4410 call build_function_call (in c-typeck.c).
4411 * typeck.c, expr.c: Use build_chill_function_call instead of
4412 build_function_call (in c-typeck.c).
4414 * parse.y (discrete_mode): Move some of the rules from
4415 non_array_mode into new non-terminal.
4416 (arrayindex): Use discrete_mode (with NAME and TYPENAME) to
4417 avoid some misparses.
4418 * ch-tree.h (SLICE_PTR, SLICE_LENGTH): Removed; unused.
4419 * convert.c (digest_structure_tuple): Add missing parameter.
4420 * decl.c (comptypes): Remove unused prototype.
4421 * decl.c (build_chill_function_type): Handle NULL return_type
4422 correctly (convert to void_type_node).
4423 * decl.c (init_decl_processing): layout boolean_type_node *after*
4424 we've set it's TYPE_MIN_VALUE and TYPE_MAX_VALUE.
4426 Wed Mar 16 16:08:22 1994 Bill Cox (bill@rtl.cygnus.com)

4429 * convert.c (convert): Correct calculation of padding length.
4430 * decl.c (grok_chill_fixedfields): Move ignore_exprs test to
4431 parse.y where it belongs. This permits the removal of a kludge
4432 in make_process_struct.
4433 * lex.l, parse.y: Call to_global_level for several errors. Add
4434 code to output error in only one pass.

4436 March 8.
4437 (build_receive_case_end): Add Wilfried's check for errors.

4444 rather than validate_varying_array_ref.
4445 * ch-tree.h: Fix prototype for valid_array_index_p.
4446 * expr.c (chill_expand_expr): Call build_chill_array_ref to get
4447 index validation.
4448 (build_hill_lower, build_chill_upper): Return value now inherits
4449 the novelty of the input parameter.
4450 (varying_to_slice): Use CH_NOVELTY macro rather than calling
4451 chill_novelty directly.
4452 * grant.c (newstring): Make len unsigned and cast xmalloc parameter
4453 to unsigned.
4454 (print_integer_type): Pass string value as APPEND's second parameter.
4455 (decode_decl): Pass a boolean expression as print_proc_tail's
4456 first parameter.
4457 (chill_finish_module_code): Make xmalloc's parameter unsigned.
4458 * lex.l: Pass sizes to xmalloc as unsigned ints. Pass second
4459 parameter to in_word_set as unsigned.
4460 * loop.c (build_loop_start): Check top_loop_end_check return value.
4461 * parse.y: Add casts to int for third do_decls parameter, fifth
4462 build_loop_iterator parameter, etc.
4463 * tasking.c (build_receive_case_end): Chack cond_stack before popping.
4464 * typeck.c (validate_varying_array_ref, chill_max_vary_array_index,
4465 valid_array_index): Delete them. They're now unused.

4467 array index is checked.
4468 (build_chill_slice): Restore old functionality where varying_to_slice
4469 is called to handle slices of varying arrays, rather than handling
4470 handling them here.
4471 (build_chill_slice_with_range, build_chill_slice_with_length):
4472 Check range limits for TREE_CONST before calling tree_int_cst_lt.
4473 Delete now-obsolete checks of constant indices.
4475 Mon Mar 14 17:26:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4477 * parse.y (modeless_expr): New rule to allow ([...]) and (if...)
4478 to count as untyped_exprs. (This is not really permitted by the
4479 Blue Book, but has been requested by customers.)
4481 Thu Mar 10 10:11:02 1994 Bill Cox (bill@rtl.cygnus.com)
4483 * chill.texi: Document new command-line options.
4484 * expr.c (build_chill_num): Set unsigned parameter for
4485 type_for_size call correctly (unsigned for enums).

4488 * lex.l: Eat more whitespace.
4490 Thu Mar 10 09:41:37 1994 Bill Cox (bill@rtl.cygnus.com)
4492 * Makefile.in: Have rules to make parse.h, y.tab.c and other
4493 derived files. This allows the gcc/configure list of CHILL
4494 files machinery to work.
4495 * ch-tree.h (permanent_allocation): Add a parameter flag.
4496 * decl.c (finish_chill_function, finish_decl): Provide the
4497 new permanent_allocation flag.
4498 (poplevel): Return early, avoid a seg fault.
4499 * lex.l (NORMAL): Replace this whole state with the predefined
4500 INITIAL state. Force compilation state to global level after
4501 compiler directive error - prevents endless loop on error.
4502 (handle_use_seizefile_directive): Rewrite for readability.
4503 (chill_same_grant_file): Reindent.
4504 Generally handle whitespace differently.
4505 * regression.prpt: Print ten PR numbers per line. The report's
4506 getting too long.
4508 Wed Mar 9 09:58:51 1994 Bill Cox (bill@rtl.cygnus.com)
4510 * decl.c (do_decl): Suppress the string-assignment-condition
4511 error - it was too often seen.
4512 * expr.c (expand_chill_expr): In CONCAT_EXPR, when argument has a
4513 runtime-changing length (as in a slice), get the parent array's
4514 allocation size from its type tree.
4515 * typeck.c (build_chill_slice): Support VARYING arrays. Pass
4516 parent array's static allocation size along in the slice type.

4524 * expr.c (build_chill_sizeof): Fix typo in error msg, add
4525 some whitespace.
4526 * lex.l (name_type_signal): Add debug output.
4527 * parse.y (call): Allow EVENTNAME and BUFFERNAME parameters
4528 to a call, so that SIZE () works on them.
4529 * tasking.c (make_process_struct): Force ignore_exprs non-zero
4530 when processing a SEIZEd PROCESS declaration. This prevents
4531 grox-fixed_fields from returning a NULL, and indirectly protects
4532 the chill_integer_type_node tree from corruption.
4534 Mon Mar 7 19:14:05 1994 Bill Cox (bill@rtl.cygnus.com)
4536 * Makefile.in: Use the 'all' target to build the runtime
4537 library and chillrt0.o.

4540 chill.regress.cron: Move to utils subdirectory.
4541 * expr.c (build_chill_function_call): Mark the INOUT
4542 temporary so it doesn't get optimized into a
4543 register. Fixes the execute/inout.ch bug.
4544 * typeck.c (layout_chill_range_type): Restrict it
4545 from complaining about an empty string type's
4546 bounds (0:-1).
4548 Mon Mar 7 09:06:39 1994 Bill Cox (bill@rtl.cygnus.com)
4550 * Makefile.in (compiler): Restore this target.
4551 (OBJS, BC_OBJS): Delete unused variables.
4552 Add $(FLAGS_TO_PASS) to sub-make invocations.
4553 * ch_decomment.l, ch_makedepend, chill.patches, printf.c,
4554 tcov.awk, tcov.el, tcov.sh: Move to utils subdirectory.

4558 * except.c (finish_handler_array): When computing address of
4559 the array ex_decl, don't call build_array_ref.

4580 * inout.c (build_chill_writetext): Add handling of a REAL.
4581 * lex.l (INITIAL): Remove all code to discard 'header lines'.
4582 no longer needed.
4583 * parse.y (optheader): Remove - it's obsolete, as is the
4584 HEADEREL token definition.
4586 Fri Mar 4 09:41:18 1994 Bill Cox (bill@rtl.cygnus.com)
4588 * addtest: Fix suffix removal when suffix is .c186.
4589 * regression.sh: Allow for underscores on PR filenames.
4590 * typeck.c: Check in the rewrite mentioned earlier.

4674 since we don't need it until we're testing.
4675 * addtest: Strip suffix from each input filename.
4676 * decl.c (do_decl): Correct error checking. Call
4677 string_assignment_condition for some of it.

4687 New cleaner solution to the following problem:
4688 Chill allows an action to be followed by an ON-handler.
4689 But we don't know if an action has a handler until we've parsed
4690 its end, yet we want to generate extra code to set up an
4691 exception handling contour only if needed. The old solution
4692 would generate code for the action into an rtl sequence, and then
4693 splice in the exception-setup code if we later found we needed it.
4694 This has a few problems (for example it confuses the management
4695 of stack temporaries), and is ugly. Now that the compiler is 2-pass
4696 we have a cleaner solution: In pass 1, we remember which actions
4697 were followed by ON-handlers. In pass 2, we use this information
4698 to generate appropriate code before an action.
4699 * except.c (push_handler, pop_handler): In pass 1, set up data
4700 structures (global_handler_list) to remember if an action has an
4701 ON-handler. In pass 2, digest this information, and setup
4702 handler if needed.
4703 * except.c, actions.h (pop_handler): Take an extra int arg.
4704 * except.c (emit_setup_handler): New function, with code (moved
4705 from chill_start_on) to emit code before an action that has a handler.
4706 * except.c (except_init_pass_2): New function.
4707 * parse.y (pass1_2): Call except_init_pass_2 before pass 2.

4710 in pass 1 as well as pass 2.
4711 * parse.y (BEGIN ... END): Re-arrange logic to avoid block_stack
4712 (local to ../stmt.c) getting out of sync.
4713 * actions.c (push_action): Don't need to emit a NOP,
4714 now that we're no longer moving sequences around.
4715 * actions.c (push_action): Call push_handler even in pass one.

5334 on constructor_stack, to allow for nested initializers.
5335 * ch-convert.c (digest_constructor): If we need a varying
5336 array, and have a constructor (for the array elements),
5337 make sure to use convert so that the constructor gets
5338 wrapped in an implicit record constructor.
5339 * ch-decl.c (do_decl): If there is no initializer for a
5340 varying array (or bitstring), create default constructor.
5342 * ch-expr.c (build_chill_lower): Fix thinko for ARRAY_TYPE.

5347 which does the actual work for build_chill_array_ref (which
5348 now just loops over an argument list).
5349 * ch-actions.c, ch-expr.c, ch-inout.c: Use build_chill_array_ref_1
5350 instead of build_chill_array_ref where appropriate.
5351 * ch-actions.c, ch-expr.c, ch-typeck.c: Make operand 1 of a
5352 VARY_ARRAY_REF is a single index, not an index list.
5354 * ch-grant.c (__init_list): Renamed to _ch_init_list, to
5355 avoid a conflict on the Alpha.
5357 Wed Jan 12 10:19:35 1994 Bill Cox (bill@rtl.cygnus.com)
5359 * ch-lex.l (WS): Add BS, VT and CR to definition of

5381 to work around a bug in /usr/ucb/cc on SunOS4.
5383 Mon Jan 10 18:29:36 1994 Bill Cox (bill@rtl.cygnus.com)
5385 * ch-actions.c (chill_convert_for_assignment): Avoid seg fault.
5386 * ch-expr.c (expand_packed_set): Add new parameter to pass
5387 set's minimum ordinal value. Fix loop invariant problem.
5388 (fold_set_expr): Change to add new parameter to
5389 expand_packed_set call.

5406 Also, fix some bugs for bitstrings (with ranges).
5408 (Patches from Tiemann.)
5409 * ch-convert.c (convert1): New function to force TREE_TYPE.
5410 (convert): Use convert1 where appropriate.
5411 * ch-typeck.c: Formatting change.
5412 * ch-parse.y (build_chill_constructor): Fix thinko.
5414 * ch-expr.c (varying_to_slice): If array is not referable,
5415 call save_expr on it, rather than stabilize_reference.
5416 * ch-satisfy.c (safe_satify_decl, for CONST_DECL):
5417 Don't force value to value class if mode is not explicitly
5418 specified. Also, make sure convert etc is only done once.
5420 Sat Jan 8 16:37:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
5422 * ch-decl.c (build_chill_function_type): Don't call
5423 build_function_type, because it does hash canonicalization,
5424 which once in a while looses badly.
5425 * tree.c (build_function_type): Remove no-longer-needed test
5426 for doing_chill_thang.
5428 * ch-tree.h (CH_DERIVED_FLAG): New flag.

5443 * ch-expr.c (finish_chill_binary_op): Use convert_to_class.
5444 * ch-satisfy.c (safe_satisfy_decl): For CONST_DECL, make sure
5445 DECL_INITIAL gets set to result of convert.
5446 Also, clear CH_DERIVED_FLAG for SYN value.
5447 * expr.c (store_constructor): If a [power]set is exactly one
5448 word long, use single-word move.
5450 Sat Jan 8 08:38:29 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5452 * c-typeck.c (chill_initializer_constant_valid_p): Fix typo.
5454 Wed Jan 5 05:18:46 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5456 * ch-typeck.c (build_chill_slice_with_length): Test that ARRAY is of
5457 ARRAY_TYPE before assuming so. Also, subtract 1 from LENGTH in
5458 computation of SLICE_END.
5460 * ch-typeck.c (chill_location): Treat CONSTRUCTORs like STRING_CSTs.
5462 * ch-expr.c (build_chill_indirect_ref): Handle MODE == NULL_TREE.
5464 * ch-expr.c (fold_set_expr): Handle OP1 == NULL_TREE (which happens
5465 for unary set operations).
5467 * ch-expr.c (build_chill_array_expr): Take new argument FORCE. All
5468 callers changed. All callers changed.
5470 * ch-convert.c (digest_structure_tuple): Handle SELECTED_VARIANT
5471 being NULL_TREE until we've started walking the list of values via
5472 the loop over VARIANTs.
5474 * ch-parse.y (build_chill_constructor): If we see an IDENTIFIER_NODE,
5475 treat it as an enum value (and hence constant). Also, only set
5476 TREE_STATIC if the constructor is indeed constant.
5477 * c-typeck.c (chill_initializer_constant_valid_p): If we see a
5478 VAR_DECL, test the TREE_CONSTANT field of the DECL_INITIAL, don't
5479 recurse on the DECL_INITIAL.
5481 Wed Jan 5 01:24:50 1994 Bill Cox (bill@cygnus.com)
5483 * Makefile.in: Add CHILL to LANGUAGES variable.
5484 * ch-actions.c (check_range): Call build_binary_op instead of
5485 fold, build to get the common types chosen.
5486 (cond_range_exception, cond_overflow_exception,
5487 cond_type_range_exception): Delete, obsolete.
5488 (chill_convert_for_assignment): Enable this, get particular
5489 about when to generate rangecheck code.

5491 perform chill_convert_for_assignment on actual parameters.
5492 (build_chill_addr_expr): Correct compiler warning.
5493 * ch-loop.c (build_chill_iterator): Add runtime check for
5494 negative loop step expression.
5495 * ch-tree.h: Add prototype.
5496 * ch-typeck.c (chill_max_vary_array_ref): Correct misunderstanding.
5497 A varying array's length field counts the NUMBER of active array
5498 array entries, not the byte-length of them.
5500 Tue Jan 4 17:57:39 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5502 * ch-decl.c (do_decl): Call `suspend_momenary' if the
5503 converted constructor must live on the permanent_obstack.
5504 * ch-convert.c (convert): When building a new SET_TYPE
5505 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5506 * c-typeck.c (chill_initializer_constant_valid_p): Handle VAR_DECLs.
5508 * ch-typeck.c (chill_location): CONSTRUCTORS that are static
5509 are locations.

5511 on permanent_obstack if necessary.
5513 * ch-convert.c (digest_structure_tuple): When building a new SET_TYPE
5514 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.

5517 the patch below helped to mess up.
5519 * ch-expr.c (build_chill_arrow_expr): Call `mark_addressable'.
5520 (build_chill_addr_expr): Take new argument ERRORMSG.
5521 All callers changed. Also, call `build_chill_addr_expr' where
5522 we used to call `build1 (ADDR_EXPR, ptr_type_node, ...)' since
5523 that now calls `mark_addressable' automagically.
5525 * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.
5526 This is needed because variables may appear in initialization
5527 statements, and their DECL_INITIALs are their values at
5528 initialization time.
5529 * ch-convert.c (digest_structure_tuple,digest_constructor): Changed
5530 to handle VAR_DECLs as initializers.
5532 * ch-convert.c (digest_structure_tuple): Copy elements of INITS so
5533 they aren't destroyed for later use.

5538 parameter for varying_array_ref calculations.
5539 (build_chill_indirect_ref): Prevent seg fault due to syntax error.
5540 * ch-typeck.c (build_chill_slice_with_range): Correct issuance
5541 of bogus error in votrics.
5542 (build_chill_slice_with_length): Change for debug tracability.
5544 Tue Jan 4 02:43:37 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5546 * ch-convert.c (digest_structure_tuple): Fix phasing problem in
5547 handling variant record initializers.
5548 (various places): Change `pop_init_level' calls to match
5549 `push_init_level' wrt implicit variable.
5551 * ch-typeck.c (build_chill_slice): Convert the dynamic max index to
5552 `integer_type_node' before using it in comparisons. FIXME: should
5553 this be done in `chill_max_vary_array_index' by default?
5555 Tue Jan 4 00:24:14 1994 Bill Cox (bill@cygnus.com)
5557 * ch-actions.c: Fix comments.
5558 * ch-parse.y: Define caseaction_flag.
5559 (caseaction): Create new caseaction_flag node at the start,
5560 then free it at the end. Check it before the ELSE code.
5561 (expanded_case_label): Check the flag here. If set in either
5562 place, generate a jump to the end of the case.
5563 * ch-typeck.c (build_chill_slice_with_length,
5564 build_chill_slice_with_range): Add lots of compile-time
5565 parameter range checking.
5567 Mon Jan 3 21:49:04 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5569 * ch-convert.c (digest_structure_tuple): Call `push_init_level' with
5570 implicit==0 everywhere, not 1.
5571 (digest_constructor): Ditto.
5573 * ch-actions.c (check_range): Permit limits to be NULL_TREE.
5574 Also, hack out some dead code.
5575 * ch-typeck.c (build_chill_slice): Check varying and non-varying
5576 slice constructs for range failures.
5577 (build_chill_slice_with_range): Reindented, but not changed.
5579 * ch-typeck.c (chill_max_vary_array_index): New function.
5580 * ch-expr.c (chill_expand_expr): Call it.
5582 * ch-decl.c (var_data_id, var_length_id): New variables.
5583 (init_decl_processing): Initialize them. All calls to
5584 get_identifier (VAR_LENGTH or VAR_DATA) are now replaced
5585 by references to these variables. This simplifies the code
5586 w/o obscuring anything.
5588 Mon Jan 3 21:24:44 1994 Bill Cox (bill@cygnus.com)
5590 * c-typeck.c: Fix comment.
5591 * ch-actions.c (chill_expand_assignment): Error assigning to
5592 READONLY location. (PR_3903) Pass filename, linenumber
5593 to setbitpowerset runtime routine.
5594 * ch-decl.c (init_decl_processing): Add filename, linenumber
5595 parameters to setbitpowerset prototype.
5596 * ch-expr.c (build_chill_function_call): Error when passing a
5597 READonly location as a LOC or INOUT parameter.
5598 * ch-parse.y (mode): Correct code marking type as readonly.
5600 Mon Jan 3 19:03:55 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5602 * ch-actions.c (chill_expand_assignment): Disable code that defeats
5603 building varying array references.
5604 * ch-expr.c (chill_expand_expr): Add rangecheck code to
5605 VARY_ARRAY_REF case.
5606 * ch-typeck.c (build_chill_array_ref): Don't call an `expand_'
5607 function (in this case, `validate_varying_array_ref') when we're
5608 doing a `build_' operation.
5610 * ch-typeck.c (validate_varying_array_ref): Simplify interface
5611 since INDEX parameter can never meaningfully be an INDEXLIST.
5612 * ch-actions.c (expand_varying_length_assignment): Caller changed.
5614 Mon Jan 3 07:29:45 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5616 * ch-typeck.c (build_chill_cast): Set TREE_CONSTANT on NOP_EXPRs.
5617 * ch-convert.c (digest_structure_tuple): Switch to permanent_obstack
5618 if we need to build a CONSTRUCTOR for a SET_TYPE initializer.
5619 (digest_structure_tuple): If TREE_VALUE (VALUE) == NULL_TREE, don't
5620 call CH_COMPATIBLE or try to convert it to TREE_TYPE (FIELD). This
5621 can happen when constructors are output incrementally.
5622 * c-typeck.c (initializer_constant_valid_p): Handle SET_TYPEs.
5623 * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
5624 CONSTRUCTORS.
5626 Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5628 * ch-convert (digest_structure_tuple): Handle SET_TYPEs. Also, call
5629 `convert' so we can handle INSTANCE types (and other anomolies)
5630 correctly.
5632 * ch-convert.c (digest_structure_tuple): Fixed variant
5633 structure initialization. Also fixed a typo (TYPE_NAME
5634 was being used on a FIELD_DECL instead of DECL_NAME).
5635 * c-typeck.c (initializer_constant_valid_p): Pass missing
5636 ENDTYPE argument on recursive call.
5637 (set_init_field): New function, needed by ch-convert.c change above.
5639 * ch-decl.c (layout_chill_variants): Added a FIXME next to an
5640 almost certain typo.
5642 * ch-expr.c (build_chill_arrow_expr): Call `build1' and set
5643 TREE_CONSTANT for static references.
5644 * ch-except.c (chill_start_on): Change calls to
5645 `build_unary_op' (which is C-specific) to `build_chill_arrow_expr'
5646 which has CHILL semantics.
5647 * ch-convert.c (convert): Ditto (albeit in some disabled code).
5649 Sat Jan 1 21:26:43 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5651 * ch-satisfy.c (safe_satisfy_decl): Reorder conditional test of
5652 TREE_CODE of DECL in case it's altered by actions in the switch.
5654 * ch-satisfy.c (satisfy): Undo abort added earlier on 1 Jan. CVS log
5655 mentions where to find code that triggers this case.
5657 * ch-actions.c (adjust_parm_or_field): Handle CONSTRUCTORS here as
5658 well.
5660 * ch-convert.c (digest_structure_tuple): Push to permanent_obstack if
5661 we're dealing with a CONSTRUCTOR that is TREE_PERMANENT.
5662 (digest_constructor): Ditto.
5664 Sat Jan 1 10:29:19 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5666 * ch-parse.y (handleraction,resultaction,assignaction,call): Modified
5667 so that CONSTRUCTORS are properly handled before being used.
5669 * ch-convert.c (chill_start_init): New function. All callers to
5670 `start_init' changed to call this function instead.
5671 (digest_struct_tuple): Defend against initialization machinery
5672 mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
5673 IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
5674 needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
5675 can be refered to throughout the compilation unit. Also remove an
5676 extraneous call to `process_init_element' erroneously added to the
5677 variant record sub-loop.
5678 (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
5679 CONSTRUCTORS of SET_TYPE.
5680 * ch-parse.y (build_chill_constructor): Refix typo. Also set
5681 TREE_STATIC if at top level.
5683 * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
5684 TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
5685 should have been called.
5687 * ch-convert.c (digest_struct_tuple): Restore code which tracks
5688 field initializations so that the compiler can deduce what variant
5689 initializations to assume.
5691 * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
5692 when we push into a scope that has a DECL with a CONSTRUCTOR as its
5693 DECL_INIT.
5695 * ch-parse.y (build_chill_constructor): Change the name of the
5696 parameter to something more meaningful. Fix typo. Also, handle case
5697 where element is an untyped CONSTRUCTOR.
5699 * ch-except.c (finish_handler_array): Set TREE_CONSTANT on
5700 constant ADDR_EXPRs.
5701 (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT
5702 on JBUF_REF (instead of calling `build1' which does not).
5704 * ch-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
5706 * ch-typeck.c (chill_expand_tuple): Deleted.
5707 * ch-parse.y (primval rule): Don't call `chill_expand_tuple';
5708 instead, use initialization machinery for CONSTRUCTORS that
5709 come through here.
5710 * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
5711 that are created here.
5712 * ch-satisfy (satisfy): Abort in case we would have called
5713 chill_expand_tuple. FIXME: some other code is needed here,
5714 but I don't know what yet.
5716 * ch-parse.y (build_chill_constructor): New function to
5717 propagate TREE_CONSTANT bits to CONSTRUCTORS.
5718 (untyped_expr rule): Use it.
5719 (primval rule): Use it.
5721 * ch-decl.c (do_decl): Call `finish_init'.
5722 * ch-convert.c (convert): If we spontaneously create a CONSTRUCTOR in
5723 this function, make sure the initialization machinery is set up.
5725 * ch-convert.c (digest_structure_tuple, digest_constructor): Add
5726 missing prototypes.
5728 Fri Dec 31 11:31:01 1993 Michael Tiemann (tiemann@blues.cygnus.com)
5730 * ch-grant.c (chill_finish_module_code): Mark ADDR_EXPR built by hand
5731 as being TREE_CONSTANT. Otherwise it gets bounded by the initializer
5732 code.
5734 * ch-decl.c (do_decl): Change in CONSTRUCTOR handling due to...
5735 * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
5736 rewritten to work with GCC's initialization code. The basic change
5737 was to keep the initializers in sync with the initialization
5738 machinery that `process_init_element' imposes. Both of these
5739 functions now return `void'.
5740 * ch-convert.c (convert): Changed calls to `digest_...' functions.
5742 FIXME: the code handling UNION_TYPE (and variant records) has not
5743 been tested yet.
5745 Fri Dec 31 15:32:56 1993 Bill Cox (bill@rtl.cygnus.com)
5747 * ch-lex.l (convert_number): Output the converted number if
5748 yydebug is enabled.
5749 * ch-parse.y (signaldef): Set ignore_exprs correctly for a
5750 SIGNAL declaration.
5752 Fri Dec 31 13:17:48 1993 Bill Cox (bill@cygnus.com)
5754 * ch-parse.y: Cleanup handling of RETURN actions, to distinguish
5755 a RETURN without a value (which cannot have an exception
5756 handler) from a RETURN with a value (which can). Eliminate
5757 some shift/reduce and reduce/reduce conflicts.
5759 Thu Dec 30 17:42:32 1993 Michael Tiemann (tiemann@blues.cygnus.com)
5761 * ch-inout.c (build_chill_writetext): Deal with 2 cases where
5762 types returned from `type_for_size' are not expected. FIXME.
5763 * ch-decl.c (init_decl_processing): Mark `char_type_node' unsigned.
5764 This is required when range checking is enabled.
5766 Thu Dec 30 14:28:25 1993 Bill Cox (bill@rtl.cygnus.com)
5768 DELAY CASE works now.
5769 * ch-decl.c (init_decl_processing): Move rest of tasking-related
5770 initialization into tasking_init().
5771 * ch-parse.y (delaycaseaction): Pervasive additions/corrections.
5772 (optsetprio): New non-terminal.
5773 * ch-tasking.c (get_task_name): Delete, obsolete.

5776 (build_receive_case_label): Move between start and end functions.
5777 (build_delay_case_start): Pass SET name and priority also.
5778 Generally update to correct functioning.
5779 (build_delay_case_label): Move between start and end fucntions,
5780 correct its functioning.
5781 (build_delay_case_end): Correct the code.
5782 (tasking_init): Lots of tasking-related code moved here from
5783 init_decl_processing.
5784 * ch-tree.h: Update, add prototypes.
5786 Wed Dec 29 10:13:10 1993 Bill Cox (bill@rtl.cygnus.com)
5788 * ch-expr.c (build_chill_indirect_ref): Revert change which
5789 failed full regression testing.
5790 * ch-lex.l (name_type_signal): Add debug output.
5791 * ch-parse.y (structured_variable): Add a debug variable.
5793 Wed Dec 29 02:05:51 1993 Bill Cox (bill@rtl.cygnus.com)
5795 * ch-decl.c (get_next_decl): Revert change which failed full
5796 regression testing.
5798 Tue Dec 28 18:20:14 1993 Bill Cox (bill@rtl.cygnus.com)
5800 DELAY actions work now.
5801 * ch-decl.c: Correct spelling in comments.

5805 * ch-expr.c (build_chill_indirect_ref): Prevent a syntax error from
5806 becoming a seg fault.
5807 * ch-grant.c: Correct a comment.
5808 * ch-loop.c: Delete/correct comments.
5809 * ch-parse.y (delaycaseaction): Add push/poplevel calls. Turn 'sorry'
5810 into rough draft of actual code.
5811 (delayaction): Don't make a new scope here, use get_unique_identifier
5812 instead.
5813 (locdec): process event decls here, too.
5814 (mode): Add code to forbid READonly EVENT and BUFFER decls. Delete
5815 code which required EVENTs and BUFFERs to be declared at global scope.
5816 (simple_name_string): Add an EVENTNAME.
5817 * ch-satisfy.c (safe_satisfy_decl): Prevent a syntax error from
5818 becoming a seg fault.
5819 * ch-tasking.c (tasking_setup): Add the event queue's max. length
5820 as the 'entry_point' parameter in the list.
5821 (build_receive_case_start, build_receive_case_label): Defer
5822 calling runtime routine until we know whether we have a signal
5823 or a buffer to wait for.
5824 (build_delay_case_start, build_delay_case_end,
5825 build_delay_case_label, build_delay_action,
5826 process_event_decls): Added functions.
5827 * ch-typeck.c (chill_similar): Allow all integers of differing
5828 precisions to be similar.
5830 Thu Dec 23 18:00:40 1993 Bill Cox (bill@rtl.cygnus.com)
5832 * gcc.c (CHILL SPECS): Delete references to -M -MM -MD -MMD
5833 options. Delete C-specific defines. Disable piping from
5834 pre-processor to cc1chill (even if -pipe is specified), since cc1chill
5835 rewinds its input for its second pass. Piping still works
5836 from cc1chill to as.
5838 Thu Dec 23 12:31:55 1993 Bill Cox (bill@rtl.cygnus.com)
5840 * ch-tasking.c (decl_tasking_code_variable): Assure that the
5841 tasking_code variable is allocated on the permanent obstack.
5842 (tasking_setup): Lots of changes - handle EVENT/BUFFER max.
5843 queue length (passed as the entry_point parameter).
5844 Other changes to variable names to increase 'self-documentation'
5845 the only kind GNU CHILL will get, for a while..
5847 Wed Dec 22 10:46:31 1993 Bill Cox (bill@rtl.cygnus.com)
5849 * ch-decl.c (do_seize): Delete - it's unused. Fix comments.
5850 * ch-loop.c (build_chill_iterator): Convert BY expression
5851 so loop involving a SET works. Additional errors generated
5852 for numbered SET expression as start or end expression.
5853 * ch-tree.h: Prototypes for future DELAY functions.
5854 * ch-typeck.c: Standard indentation.
5856 Tue Dec 21 15:30:57 1993 Per Bothner (bothner@kalessin.cygnus.com)

5871 Return 2 if also a referable.
5872 * ch-typeck.c (chill_referable): Re-define to use chill_location.
5873 * ch-tree.h (CH_EQUIVALENT): Re-defined to use chill_equivalent.
5875 * dbxout.c (dbxout_type): Output the type attribute "@S;" to
5876 distinguish a string from a char array, and to distinguish a
5877 bitstring from regulat (power)set. (Needed for Chill.)
5878 * dbxout.c (dbxout_type): Only check for baseclasses in
5879 type.binfo is a vector. (It is used in Chill for tagged unions.)
5881 Fri Dec 17 09:56:07 1993 Bill Cox (bill@rtl.cygnus.com)
5883 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
5884 ch-grant.c, ch-inout.c, ch-loop.c, ch-parse.y,

5896 the expressions in a STEP loop.
5897 * ch-tasking.c (rc_state): Add fields to flag SIGNAL and BUFFER
5898 names in receivecasealternative. Generate error messages
5899 if they're mixed in the same receive case.
5900 (process_buffer_decl): Renamed from build_buffer_decl.
5901 * ch-tree.h: Fix prototypes.
5902 * ch-typeck.c (smash_dummy_type): Handle all four kinds of LANG_TYPE

5912 * ch-loop.c (declare_temps): Calculate end-of-array pointer

5914 (begin_chill_loop): Build loop-bypass expression in the
5915 type of the start expression, not in the unsigned type.
5917 Tue Dec 14 15:41:32 1993 Per Bothner (bothner@kalessin.cygnus.com)
5919 * ch-decl.c (push_scope_decls): Re-arrange so that normal
5920 (non-seize) declarations are proclaim_decl'd *before* we
5921 handle the ALIAS_DECLs for seizes. The advantage is
5922 that we can now test for (an approximation) to the
5923 'seizeable' concept, thus avoiding duplicate definitions
5924 when a module has both GRANTs and SEIZE ALL.
5926 * ch-expr.c (build_chill_arrow_expr): No longer re-write
5927 addr-of-conversion to pointer-conversion-of-addr.
5928 * ch-expr.c (build_chill_addr_expr): Re-write to just use

5933 * ch-expr.c (build_chill_addr_expr, build_chill_addr_expr): Don't re-write
5935 * ch-tree.h (chill_root_resulting_mode): Fix typo (missing '_').
5937 * ch-expr.c (finish_chill_binary_op): Use CH_ROOT_RESULTING_MODE
5938 macro (which works on expressions), rather than CH_RESULTING_MODE
5939 (which works on modes, and isn't quite correct).
5940 * ch-tree.h (CH_IS_BOUND_REFERENCE_MODE): New macro.
5941 * ch-typeck.c (chill_read_compatible, chill_compatible):
5942 Use the new macro, which handles NEWMODEs of PTR correctly.
5943 * ch-typeck.c (chill_similar): Return 1 rather than 0 for
5944 dynamic-length array (and string) types (e.g. slices).
5945 * ch-typeck.c (chill_root_mode): If the mode has a Novelty,
5946 just return it as is. (This is still not 100% correct for
5947 NEWMODE of RANGEs, but is close enough.)
5949 Mon Dec 13 16:27:06 1993 Bill Cox (bill@rtl.cygnus.com)
5951 * ch-parse.y (locdec): Avoid passing IDENTIFIER_NODEs to

5954 of bufdecl closer to its use.
5956 Mon Dec 13 14:57:55 1993 Bill Cox (bill@rtl.cygnus.com)

5961 * ch-parse.y (sendaction): Delete unused statement, use the 'name'
5962 variable.
5963 * ch-tasking.c: Use expand_expr_stmt to avoid C-specific
5964 conversions.
5965 (build_buffer_decl): Save the tasking_code_variable's decl
5966 in the buffer decl tree.
5967 (build_buffer_descriptor): Real, working version.
5969 Mon Dec 13 03:13:36 1993 Bill Cox (bill@rtl.cygnus.com)
5971 * ch-decl.c (print_lang_identifier): Delete code
5972 to print buffer size - it's no longer kept here.
5973 * ch-parse.y (expand_send_buffer): Renamed from
5974 build_send_buffer.
5975 (locdec): Enable building of a buffer decl.
5976 (optresultspec, optresultattr): Add optional

5981 * ch-typeck.c (chill_expr_class): Do more complete,
5982 job of classifying expressions. Thanks, Per.

5987 for bitstring constants.
5988 * ch-typeck.c (chill_novelty): The novelty of an (unnamed)
5989 range mode is that of its parent mode; the novelty of READ M
5990 is that of M.
5992 Sat Dec 11 15:14:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
5994 * ch-expr.c (varying_to_slice): Call stabilize_reference
5995 rather than save_expr.
5996 * ch-typeck.c (build_chill_slice): Don't emit warning
5997 if array is a SAVE_EXPR (it is effectively referable).
5998 * ch-typeck.c (chill_root_resulting_mode): Handle
5999 correctly the case that one operand is DERIVED and one is VALUE.

6023 assignment, check that all the targets are equivalent.
6025 * ch-typeck.c (chill_l_equivalent, CH_L_EQUIVALENT): New function

6028 initial check of read-only-ness.
6029 * ch-typeck.c (build_readonly_type): Fix thinkos.
6031 Wed Dec 8 09:11:46 1993 Bill Cox (bill@rtl.cygnus.com)
6033 * ch-decl.c (pop_module): Only warn about duplicate grant

6041 * ch-decl.c (start_chill_function): Handle attributes in pass 1,
6042 rather than in pass 2. (It seems to make more sense that way.)
6043 * ch-parse.y (procedureattr): Build attribute list if pass != 2.
6045 * ch-parse.y (mode): Don't call build_readonly_type in pass 2.
6047 Mon Dec 6 14:35:31 1993 Per Bothner (bothner@kalessin.cygnus.com)
6049 This implements NOVELTY and READONLY checking.

6052 * ch-tree.h: New prototypes.
6053 * ch-decl.c (push_modedef): If newmode, lazily "copy" the given mode
6054 immediately (even if it's just a type name), using a LANG_TYPE.
6055 * ch-parse.y (mode): Call build_readonly_type to handle READ.
6056 * ch-decl.c (find_implied_types), ch-grant.c (raw_decode_mode),
6057 ch-satisfy.c (satisfy): Handle a LANG_TYPE.
6058 * ch-decl.c: Remove chill_modes_equiv and other unused junk.
6059 * ch-satisfy.c (safe_satisfy_decl/CONST_DECL): Better
6060 mode compatibility checking for SYN declarations.
6062 * ch-typeck.c (chill_similar): Be more general when checking set
6063 modes for similarity - specifically support calling chill_similar
6064 BEFORE the modes have been satisfied (needed by proclaim_decl).
6065 * ch-decl.c (proclaim_decl): Allow duplicate definitions

6560 a handler following BEGIN END comes before the final poplevel.
6561 * ch-typeck.c (build_chill_cast): Just return if already correct type.
6563 Re-do DO WITH so that build_component_ref for is done lazily
6564 (at each reference) instead of eagerly (at the beginning
6565 of DO WITH). This is needed for tagged variants,
6566 * ch-tree.def (WITH_DECL): New declaration tree code.
6567 * ch-decl.c (lookup_name): Recognize WITH_DECLs.
6568 * ch-decl.c (handle_one_level): Variant parts are currently

6614 builtins have a pointer-to-pointer-to-void
6615 first parameter, rather than a reference parameter.
6616 * ch-expr.c (build_allocate_memory_call,
6617 build_allocate_global_memory_call): Do automatic
6618 ADDR () on the first parameter, for backward
6619 compatibility.

6655 code variables associated with a process or signal.
6656 * ch-tasking.c (build_gen_inst, build_gen_ptype): Use the decl's
6657 tasking_code_decl pointer, rather than trying to look it up
6658 in the hash table or linked scope list.
6660 Wed Oct 20 09:52:44 1993 Bill Cox (bill@rtl.cygnus.com)
6662 * ch-actions.c (lookup_and_handle_exit): Only output error message

6671 static variable, point the process' function_decl at it for later
6672 reference by build_start_process.
6673 (print_mode): Use CHILL upper-case convention to print modes.
6674 * ch-lex.l: Must initialize tasking-related trees to NULL at start
6675 of each pass, or we lose the fact that the user did or did not
6676 specify a value for each of them.
6677 * ch-parse.y (check_end_label, action, exceptlist): Only output
6678 error message in pass 1.
6679 (sendaction): Add comments.

6684 passes, using do_decl so we can pass the pass 2 value of the
6685 process_type or signal_code to it. Only update the process_type
6686 if the incoming pointer isn't null and pass == 2. Use a new
6687 parameter to know whether to include an init expression.
6688 (build_process_header): Attach tasking-code_variable to process

6704 generation for decls to not use DECL_ASSEMBLER_NAME.
6705 * ch-decl.c: Set DECL_ASSEMBLER_NAME to DECL_NAME.
6706 This matches C, and allows dbxout to emit proper user-level names.

6709 into the outer scope.
6710 (pop_module): Change code that grants into outer scope accordingly.

6725 * ch-tree.h: Restore old version.
6726 * ch-expr.c (finish_chill_binary_op): Convert TRUNC_DIV_EXPR
6727 to RDIV_EXPR if an operand is floating. (This functionality

6731 not error_mark_node.
6732 * ch-actions.c (chill_expand_assignment): Allow such borderline

6752 commented-out code as example for assignment of module address to its
6753 init_list entry.
6755 Sun Oct 17 15:16:54 1993 Bill Cox (bill@cygnus.com)
6757 * ch-convert.c: Move semicolon to separate line - easier to see.
6758 * ch-decl.c (do_decl): Handle untyped_expr initializers by
6759 simply using the variable's declared type - no compatibility
6760 check can be made if the expression has no type.

6762 the loop variable.
6763 (fold_set_expr): Fix two other endless loops by passing
6764 correct parameters to unpack_set_constructor.

6944 * ch-parse.y (sigdef): .. here. And make indentation changes.
6945 * ch-tree.h: Rename functions, add return values.
6947 Mon Oct 4 15:43:56 1993 Per Bothner (bothner@kalessin.cygnus.com)
6949 * ch-convert.c (digest_constructor): Convert element to element_type.
6950 * ch-parse.y (end_function): Use DECL_ARGUMENTS to check
6951 for parameterless process.
6953 Fri Oct 1 13:57:30 1993 Per Bothner (bothner@kalessin.cygnus.com)
6955 * ch-typeck.c (chill_location): New function.
6956 Based on lvalue_p, but also handle Chill-specific VARY_ARRAY_REF.
6957 * ch-typeck.c, ch-tree.h (CH_LOCATION_P), ch-convert.c: Use
6958 chill_location instead of lvalue_p.
6961 Fri Oct 1 11:28:42 1993 Bill Cox (bill@cygnus.com)
6963 * ch-convert.c (convert): Back out Michael's changes, unintentionally
6964 checked in.
6965 * ch-lex.l (handle_use_seizefile_directive): No longer downcase
6966 seize file names.
6967 * ch-parse.y (sendaction): Fix a couple of seg faults. Comment out
6968 SEND BUFFER processing for now.
6969 * ch-tree.h: Fix comment.
6971 Thu Sep 30 17:00:42 1993 Per Bothner (bothner@kalessin.cygnus.com)
6973 * ch-tree.h (CH_CHARS_ONE_P, CH_BOOLS_ONE_P): New macros,
6974 for recognizing singleton strings.
6975 * ch-tree.h (MARK_AS_STRING_TYPE): New macro.
6976 * ch-tree.c (build_string_type, build_bitstring_type),
6977 ch-convert.c (convert): Use it.
6978 * ch-typeck.c (build_chill_slice): Take length rather than upper
6979 bound. This makes it easier to recognize that A(X UP LENGTH)
6980 really has fixed length. Also, if the argument is string,
6981 mark the slice as a string too. Also, handle varying strings.
6983 * ch-typeck.c (conflate_singleton_strings): New global.
6984 * ch-typeck.c (chill_similar): If conflate_singleton_strings is
6985 set (as it currently is), allow CHARS(1)/BOOLS(1) to be similar
6986 to CHAR/BOOL, as required by the 1984 version of Z.200.
6987 * ch-convert.c (convert_to_char): Convert CHARS(1) to CHAR.
6988 * ch-convert.c ( build_array_type_for_scalar): If input is string,
6989 so is output.
6990 * ch-convert (maybe_turn_scalar_into_arra), ch-tree.h: Removed.
6991 * ch-convert.c (convert): Convert CHAR to CHARS(1).
6993 This fixes 'X // := Y' and is also a general simplification.
6994 * ch-actions.c (chill_expand_assignment): Convert 'LHS OP := RHS'
6995 to 'LHS := LHS OP RHS' (using stabilize_reference on LHS).
6996 Also, call save_expr on RHS if a multiple assignment.
6997 * ch-parse.y (assignaction): Therefore, no longer need to call
6998 stabilize_reference on RHS.
6999 * ch-typeck.c (build_chill_modify_expr), ch-tree.h: Remove
7000 modifycode parameter. Make it the caller's responsibility to
7001 handle <assigning operator>.
7002 * ch-actions.c, ch-decl.c, ch-except.c, ch-expr.c, ch-grant.c,
7003 ch-loop.c: Fix calls to build_chill_modify_expr accordingly.
7005 Wed Sep 29 18:02:55 1993 Per Bothner (bothner@kalessin.cygnus.com)
7007 * ch-lang.c (string_index_type_dummy), ch-tree.h: New variable.
7008 * ch-decl.c (integer_minus_one_node), ch-tree.h: New variable.
7010 * ch-parse.y (arrayindex: modename): Remove useless code.
7011 * ch-satisfy.c (satisfy): Don't gag on string_index_type_dummy,
7012 * ch-tree.c (build_string_type): Pass string_index_type_dummy as
7013 the parent type of the index range.
7014 * ch-typeck.c (layout_chill_range_type): Recognize and handle
7015 string_index_type_dummy - specifically allow an empty range.
7017 Wed Sep 29 13:36:23 1993 1993 Bill Cox (bill@cygnus.com)
7019 * ch-convert.c (convert_to_reference): Check for loc-identity
7020 mismatches correctly (and remove one of those chill_compatible
7021 calls).
7022 * ch-decl.c (decl_tasking_code_var): New function, called from
7023 push_extern_process and push_extern_signal.
7024 * ch-parse.y (end_function): Delete parameter. Check current_function_decl
7025 whether it's actually a process, and whether it has parameters.
7026 Make Michael's change simplifying the pass 2 test, preventing a seg
7027 fault.
7028 (procedure, process): Change calls to end_function, remove
7029 code saving value from build_process_header. Delete redundant chill_
7030 phrases from some function calls.
7031 * ch-tasking.c: Remove some redundant _chill phrases from function
7032 names.
7033 * ch-tree.h: Remove some redundant _chill phrases from function
7034 names. Add the CH_VARYING_ARRAY_TYPE macro, call it from
7035 all relevant places.
7036 * ch-typeck.c: Use the new macro. Cast TREE_CODEs to chill_tree_code.
7038 Wed Sep 29 13:07:43 1993 Per Bothner (bothner@kalessin.cygnus.com)
7040 * ch-convert.c (convert_to_reference): Remove redundancies.
7041 * ch-convert.c (convert): Handle convert_to_reference
7042 with a recursive convert call.
7043 * ch-decl.c (do_decl): Add missing compatibility-checking
7044 of initializer (don't depend on convert).
7046 Tue Sep 28 00:02:25 1993 Per Bothner (bothner@kalessin.cygnus.com)
7048 * ch-tree.h (CH_LOCATION_P): New macro.
7049 * ch-typeck.c (layout_chill_range_type): Fix call to
7050 type_for_size, when figuring out a defaulted parent type.
7051 * ch-expr.c (build_chill_lower, build_chill_sizeof): Check
7052 for TREE_CODE_CLASS != 't' rather than == 'd'.
7053 * ch-expr.c (build_chill_function_call): Use CH_LOCATION_P
7054 to check for location, rather than TYPE_CODE_CLASS == 'd'.
7056 * ch-tree.c (build_string_type): Make 2-pass safe. Also,
7057 change parameter to be length, not index type.
7058 * ch-parse.y (mode2), ch-expr.c (build_concat_expr), ch-lex.l
7059 (build_chill_string): Modify callers of build_string_type accordingly.
7060 * ch-lex.l (check_newline): Don't look for # directive inside a
7061 C-style comment.
7062 * ch-grant.c (grant_array_type): Make more robust for char-
7063 and bit-strings (allow non-constant sizes). Change parameters
7064 and return types. (raw_decode_mode): Use grant_array_type
7065 for bitstrings. (otherwise): Fix grant_array_type callers.
7067 Mon Sep 27 16:57:57 1993 Per Bothner (bothner@kalessin.cygnus.com)
7069 Remove changes of Sep 15.
7070 * ch-tree.h (CH_SINGLETON_DOMAIN): Removed.
7071 * ch-typeck.c (chill_similar): Don't allow a singleton
7072 powerset to be similar to its domain.
7073 * ch-convert.c (convert_to_boolean): Don't convert a singleton
7074 SET_TYPE constructor to a Boolean.
7076 * ch-actions.c (chill_expand_assignment): Handle IN_EXPR on
7077 LHS of assignment, which is what we're current (temporarily?) using.
7079 Mon Sep 27 06:01:57 1993 Bill Cox (bill@rtl.cygnus.com)
7081 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
7082 ch-grant.c, ch-inout.c, ch-parse.y, ch-satisfy.c,
7083 ch-tasking.c, ch-tree.c, ch-tree.h, ch-typeck.c:
7084 -Wall cleanup. Add prototypes where missing.
7085 Delete unused variables. Cast uses of tree_codes
7086 to chill_tree_code, which they are.
7088 Sun Sep 26 13:09:57 1993 Bill Cox (bill@rtl.cygnus.com)
7090 * ch-decl.c (do_decl): Save initializer in pass zero
7091 case also.
7092 * ch-lex.l: Fix comments, indentation.
7093 * ch-parse.y: Standardize error messages to use
7094 uppercase for CHILL keywords rather than quoting them.
7095 Suggestion from docs department.
7096 * ch-tasking.c: Pervasive changes to get processes to
7097 compile and START.
7098 * ch-tree.h: Delete prototypes for functions whic
7099 I made static inside ch-tasking.c.
7101 Sun Sep 26 02:40:02 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7103 * ch-lex.l (yywrap): Call `check_newline' in case the file
7104 started with a line directive.
7106 Sat Sep 25 13:54:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
7108 * ch-decl.c: Expand pre-amble comment.
7109 * ch-decl.c (struct scope, push_module): Use new field
7110 tail_chain_module to build child-module list in order.
7111 (Just to make compiler debugging a little less confusing.)
7113 * ch-decl.c (struct scope): New field weak_decls.
7114 * ch-decl.c (find_implied_types): New interface. Now pre-pend
7115 new enum types to a given input list. This makes it easier to
7116 avoid duplicates, which should at least be more efficient.
7117 Also, handle FUNCTION_DECL.
7118 * ch-decl.c (bind_saved_names): Removed. Distribute its
7119 functionality over new functions (push_scope_decls, pop_scope_decls,
7120 build_implied_names, bind_sub_modules). The goal (which seems to
7121 have been more-or-less attained) was to fix weak name handling.
7122 * ch-decl.c (poplevel): Use new function pop_scope_decls.
7124 * ch-tasking.c (build_signal_struct, build_tasking_message_type):
7125 Use build_decl directly, rather than grok_chill_fixedfields
7126 (which depends on ignore_exprs and has more overhead).
7127 * ch-tasking.c (build_signal_struct): Construct the type
7128 only in pass 1.
7129 * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
7130 than build_array_ref (which does C-specific "optimizations").
7131 (Hence move my_build_array_ref up earlier in the file.)
7133 Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7135 * ch-tasking.c: Declare static variable `void_ftype_void'.
7136 (chill_tasking_init): Initialize `void_ftype_void' here.
7137 (build_tasking_struct): Use, don't declare `void_ftype_void'.
7138 (generate_tasking_code_variable): Call `do_decl', not
7139 `decl_temp1' to declare TASKING_CODE_NAME.
7140 (tasking_setup): Drop into 1-pass mode so that all
7141 tasking-related declarations are installed in the global
7142 scope. Use correct CHILL types for initializers (since
7143 ptr_type_node doesn't have the right meaning for CHILL).
7144 Also, call `do_decl' instead of `decl_temp1' for
7145 `init_struct'.
7146 (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
7147 `chill_finish_compile' in sync between passes.
7149 * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
7150 declarations on pass zero. Keep obstacks in sync, and always
7151 call `finish_decl' for pass zero declarations.
7152 (push_chill_extern_function): Keep obstacks in sync, and always
7153 call `finish_decl' for pass zero declarations.
7154 (build_enumerator): Ditto.
7155 (grok_chill_variantdefs): Change PASS test to exclude only
7156 pass one.
7157 (finish_struct): Ditto.
7158 * ch-expr.c (build_chill_component_ref): Ditto.
7159 (build_chill_binary_op): Ditto.
7160 * ch-tree.c (build_powerset_type): Ditto.
7161 (build_bitstring_type): Ditto.
7162 * ch-typeck.c (build_chill_range_type): Ditto.
7163 (build_chill_struct_type): Ditto.
7165 * ch-decl.c (build_chill_exception_decl): Clarify reasons for
7166 extra pushing and popping of obstacks.
7168 * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
7169 on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
7171 * ch-grant.c (chill_finish_compile): Clear out both
7172 MODULE_INIT_LIST and TASKING_LIST if either contains stuff
7173 from pass one.
7175 * ch-parse.y (rccase_label): Add NAME rules so that pass one
7176 works w/o knowing we're parsing a signal. Simplify SIGNALNAME
7177 rules since we only get SIGNALNAME tokens in pass two.
7178 (sendaction): Ditto.
7179 * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
7180 BUFFERNAME on pass two. The grammar now handles this.
7181 * ch-decl.c (lookup_remembered_decl): Deleted.
7183 Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
7185 * ch-decl.c (lookup_remembered_names): Removed. It was being
7186 misused in ch-lex.l.
7187 * ch-lex.l (name_type_signal): Revert last change. Basically,
7188 we cannot use the C typedef/variable name trick in CHILL, due
7189 due to the language's 2-pass nature.
7190 * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
7191 a seg fault.
7192 * ch-tree.h (lookup_remembered_name): Comment out the prototype.
7194 Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7196 * ch-decl.c (do_decl, push_chill_extern_function): Change pass
7197 checks so the pass == 0 case is handled for built-in types.
7198 (push_modedef): Add check for error_mark_node.
7199 (lookup_remembered_decl): New function.
7200 (pushlevel, poplevel) Change pass checks.
7201 (pushdecl): Check type as well for NULL.
7202 (build_enumerator): Handle pass == 0 case.
7203 * ch-lex.l: Use lookup_remembered_decl to get lastiddecl
7204 during pass 1.
7205 * ch-parse.y: Set pass to zero to indicate initial decl processing.
7206 Replace NAME references with SIGNALNAME references.
7207 (startaction): Only check copy number if not ignoring actions.
7208 Always call build_chill_start_process.
7209 (optstartset): Don't lookup the instance name.
7210 * ch-tasking.c (generate_tasking_code_variable): Replace
7211 do_decl call with decl_temp1 call.
7212 (build_chill_start_action): Check for ignore_actions here.
7213 (build_tasking_message_type): Layout the type.
7214 (rc_state_type): New structure to keep nested receive-case
7215 info in.
7216 (build_chill_receive_case_start, build_chill_receive_case_end):
7217 Use the new struct.
7220 Fri Sep 24 04:19:15 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7222 * ch-tasking.c (build_chill_receive_case_start): `namedecl'
7223 should be a _DECL, not an IDENTIFIER_NODE.
7225 Thu Sep 23 18:18:24 1993 Per Bothner (bothner@kalessin.cygnus.com)
7227 * ch-decl.c (find_implied_types): Handle VAR_DECLs.
7229 * ch-decl.c (print_lang_identifier): Print IDENTIFIER_OUTER_VALUE.
7230 * ch-actions.c (chill_expand_result): Allow value-less RETURN.
7231 * ch-expr.c (resolve_component_ref): Recognize error_mark.
7233 * ch-convert.c (digest_constructor): Handle a nested powerset tuple.
7234 * ch-satisfy.c (satisfy): Use return value of layout_chill_range_type.
7235 * ch-typeck.c (chill_similar): Repeatedly get parent modes
7236 of ranges, not just once.
7237 * ch-typeck.c (chill_root_resulting_mode), ch-tree.h: New function.
7238 * ch-typeck.c (layout_chill_rang_type): Re-do type-checking
7239 to follow Blue Book better (check for Compatibility).
7241 * ch-tree.h (CH_ROOT_RESULTING_MODE): New macro.
7242 * ch-lex.l (use_seizefile_name, current_seizefile_name), ch-tree.h:
7243 New variables. The latter replaces in_seizefile.
7245 Changes to store in the new DECL_SEIZEFILE field each seize
7246 ALIAS_DECL the name in the most recent use_seize_file directive.
7247 (This requires that use_seize_file directives written to the
7248 grant file be written before the SEIZEs that need it.)
7249 Allow clashing declarations granted into the global scope
7250 (produce a warning), but remember the seizefile case from
7251 (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
7252 The a SEIZE will select the granted decl that matches its
7253 DECL_SEIZEFILE (in other words: grants from the most recent
7254 use_seize_file will be preferred).
7255 * ch-tree.h (DECL_SEIZEFILE), ch-tree.def: New macro.
7256 * ch-tree.h (global_value, IDENTIFIER_GLOBAL_VALUE): Renamed
7257 to outer_value, IDENTIFIER_OUTER_VALUE.
7258 Changes to cause the use_seize_file directives to be written
7259 out in order as they're seen in source.
7260 * ch-lex.l (files_to_seize, next_file_to_seize, last_file_to_seize):
7261 Changed to have type TREE_LIST of pointer to IDENTIFIER_NODE.
7262 * ch-lex.l (handle_use_seizefile_directive): Modify appropriately.
7263 Don't call grant_use_seizefile.
7264 * ch-lex.l (mark_use_seizefile_written): New function.
7265 * ch-grant.c (decode_decl): Write out use_seize_file directive,
7266 if needed, before writing a seize declarations.
7267 * ch-decl.c (pop_module): Handle decls granted into the global
7268 module specially, setting IDENTIFIER_OUTER_VALUE.
7269 * ch-decl.c (lookup_name_for_seizing): Check IDENTIFIER_OUTER_VALUE.
7271 Thu Sep 23 19:05:37 1993 Bill Cox (bill@cygnus.com)
7273 * ch-decl.c (push_chill_extern_process): Delete unused variables,
7274 declare the process' tasking_code variable as external.
7275 * ch-parse.y (process): Force ignore_exprs to FALSE while parsing
7276 the process header.
7277 * ch-tasking.c (sigdef): Move resetting of quasi_signal from here
7278 to (signaldef).
7279 * ch-tree.h: Add prototype.
7280 * expr.c (store_constructor): Emergency first-aid. Rewrite later.
7282 Thu Sep 23 12:57:53 1993 Per Bothner (bothner@kalessin.cygnus.com)
7284 * ch-expr.c (build_chill_function_call): Move possible call to
7285 chill_start_module_code until we know we're not calling a builtin.
7286 * ch-decl.c (save_expr_under_name): Use pushdecllist,
7287 not proclaim_decl (which provide for popping the decl).
7288 * ch-parse.y (optname): Also allow TYPENAME.
7290 Thu Sep 23 09:18:35 1993 Bill Cox (bill@cygnus.com)
7292 * ch-decl.c (print_lang_decl): Make weak name output more standard.
7293 (print_lang_identifier): Make signal-data flag output more standard.
7294 (push_chill_extern_process): Pass correct arg tree to
7295 push_chill_extern_function.
7296 (push_syn_decls, fixup_unknown_type, chill_modes_equiv):
7297 Standardize function header layouts (Makes the tcov script
7298 work better).
7299 * ch-except.c (chill_finish_on): Standardize function header.
7300 * ch-expr.c (fold_set_or): Standardize function header.
7301 * ch-grant.c (print_proc_tail, print_proc_exceptions): Standardize
7302 function headers.
7303 (decode_constant): Make sure that alpha operators are surrounded
7304 with whitespace.
7305 * ch-parse.y: Spell Z.200 correctly in comments.
7307 Wed Sep 22 10:42:31 1993 Per Bothner (bothner@kalessin.cygnus.com)
7309 * ch-expr.c (build_chill_addr_expr), ch-tree.h: New function.
7310 * ch-parse.y, ch-decl.c (shadow_record_fields): Use it.
7311 * ch-lex.l (handle_use_seizefile_directive): Don't emit
7312 use_seize_file directive if in_seizefile.
7314 * ch-convert.c (digest_structure_tuple): Fix code that checks
7315 for excess init values.
7316 * ch-decl.c (layout_chill_variants): Move increment of nlabels
7317 inside the proper loop.
7318 * ch-grant.c (print_struct): Add missing loop for tag_list.
7319 (print_struct): Look for variant fields by checking for a
7320 UNION_TYPE, not a NULL name, since we must use a dummy name.
7321 * ch-parse.y (structured_variable): Various fixing.
7322 * ch-decl.c (shadow_record_fields): Rename arg decl -> struct_val.
7324 * ch-satisfy.c (safe_satisfy_decl): Disable copying of modes
7325 for NEWMODE (and hence novelty checking), until we figure out
7326 a better way.
7328 * ch-except.c (finish_handler_array): Use null_pointer_node,
7329 not integer_zero_node (which fails to type-check).
7331 * c-typeck.c (get_constructor_element_type): New function.
7332 * ch-tree.h (CH_NOVELTY_FLAG): Now also used in TYPE_DECLs.
7333 (CH_NOVELTY): Redefined to call new function chill_novelty.
7334 (CH_CLASS_IS_XXX, TYPE_NEWMODE, CH_CLASS_MODE): Removed.
7335 * ch-typeck.c (classify_chill_expr renamed to chill_expr_class):
7336 Take extra output parameter (for M, as in M-value class).
7337 * ch-typeck.c (chill_novelty): New function. (Also de-references.)
7339 * ch-expr.c (resolve_component_ref, build_chill_component_ref):
7340 New functions. Handle 2-pass and variant records.
7341 * ch-parse.y (primval DOT name): Use instead of build_component_ref.
7342 * ch-satisfy.c (satisfy, case COMPONENT_REF):
7343 New case, call resolve_component_ref.
7345 * ch-expr.c (build_generalized_call): Extract single arg from
7346 arg list before calling build_chill_cast.
7348 * ch-parse.y (defining_occurrence_list): New non-terminal.
7349 Use it to replace locnamelist, synnames, and modenames.
7350 * ch-parse.y: Re-write parsing of variant records.
7352 * ch-decl.c (grok_chill_variantdefs): Now return a FIELD_DECL
7353 rather than just its type.
7354 * ch-inout.c (build_chill_io_list_type), ch-parse.y:
7355 Change callers appropriately.
7357 * ch-tree.h (TYPE_TAG_VALUES): Add an extra level of TREE_LIST,
7358 to support multiple tag fields.
7359 * ch-grant.c (print_struct), ch-decl.c (layout_chill_variants):
7360 Support multiple tag fields.
7362 * ch-convert.c (remove_tree_element, digest_structure_tuple):

7387 doing the type's layout.
7388 (processpar): Use paramnamelist, but reformat it into a

7392 type's layout.
7393 * ch-tasking.c (generate_tasking_code_variable): Call do_decl to

7434 Fri Sep 10 12:23:41 1993 Wilfried Moser (fs_moser@cygnus.com)
7436 * Makefile.in: Change installation of the chill script. gcc will
7437 be called always with the full path. That made problems when

8638 labels aren't lowercased before their time. Add BEGIN
8639 INITIAL before starting pass 2, so the header is

10091 Major re-write of New module/seize/grant stuff.
10092 Now, a grantfile is a spec module and contains all the
10093 top-level declarations of the granting module, not just
10094 those that are granted. It also contains explicit grant
10095 statments naming those declared names that are granted.
10096 It also has seize statements and use_seize_file directives
10097 to correctly handle transitive dependencies.
10099 * ch-parse.y: Change to allow multiple modules per source file.
10100 Allow spec modules (including quasi definitions) as well as
10101 regular modules.
10102 Allow spec modules inside normal modules; these behave as if
10103 they were outermost. This violates the Blue Book, but is
10104 needed by the new grantfile mechanism. (A grant file is a
10105 spec module that gets included by the use_seize_file directive.)
10106 * ch-parse.y (struct module *current_module, push_module,
10107 pop_module): Support module nesting (for spec modules only).
10109 * ch-tree.h (struct module): New.
10110 * ch-grant.c (granted_decls): New list of declarations
10111 that have been granted into the outermode pseudo-module.
10112 * ch-grant.c (decode_mode): If the decl has a name,
10113 always write the name, not just if the decl has already
10114 been written. Since we write out all decls, we can assume
10115 it will be written later, and depend on the forward
10116 declaration kludges to catch it.
10117 * ch-grant.c (decode_decl): Don't write out _EXTERN.
10118 Instead write out standard (Blue Book) quasi-definitions.
10119 * ch-grant.c (push_granted): New function.
10120 * ch-grant.c (seize_implied_names): New function. Re-write
10121 how set element names are seized when a set type is seized.
10122 * ch-grant.c (chill_seize): Work by seraching the
10123 granted_decls list and copying the declaration.
10124 * ch-grant.c (chill_grant): Write all declarations
10125 declared in this module. Write GRANT statements for
10126 those granted. seize statements for decls seized from
10127 other modules. Write extra syntax to make a complete
10128 spec module.
10129 * ch-grant.c (grant_use_seizefile): Copy use_seize_file
10130 directives into grant file.
10131 * ch-lex.l (setup_seizefile_read): Call grant_use_seizefile.
10133 * ch-lex.l (struct input_state, current_input_state,
10134 push_input_file, pop_input_file): New (type, variable,
10135 function*2). Used to save and restore state on an input file.
10136 * ch-lex.l: Clean up to handle nested input seizefiles
10137 (needed by new grant/seize mechanism.
10138 * ch-lex.l (skip_to_end_of_directive): New function.
10139 * ch-lex.l (compiler_directive: USE_SEIZE_FILE): Make sure
10140 we skip to the end of the directive *before* we switch
10141 input files.
10142 * ch-lex.l (setup_seizefile_read): Prevent reading the
10143 same seizefile twice (otherwise likely with new grant/seize).
10144 * ch-lex.l: Recognize SPEC. Misc cleanups.
10146 * ch-parse.y: Fixed foreward references of types.
10147 Removed the unknown_type_node crock.
10148 * ch-decl.c: Remove all uses of unknown_type_node.
10149 Check for TYPE_SIZE zero instead.
10150 * ch-decl.c (fixup_unknown_type): Make sure new mode
10151 gets copied into old mode. Merge their variant chains.
10152 * c-decl.c (lookup_name_current_level): Make non-static.
10153 * ch-decl.c (lookup_name_current_level): No longer needed.
10155 * ch-parse.y (call): Allow an implicitly defined function
10156 name following the CALL keyword.
10157 * ch-tree.h (struct lang_identifier): Add implicit_decl,
10158 and make sure order of fields matches c-tree.h.
10160 * ch-actions.c (lang_init, build_allocate_memory_call,
10161 build_allocate_globals_memory_call): Fix names (add initial '_')
10162 and prototypes of _allocate_[global_]memory (2nd param is ref).
10163 Use build_chill_function_call, not build_function_call,
10164 so the reference parameter gets handled.
10165 * ch-actions.c. (lang_init): Make sure boolean_{true,false}_node
10166 have boolean_type_node as their types.
10167 * ch-actions.c (build_chill_lower, build_chill_upper): Fix to
10168 work for arrays with BOOLEAN_TYPE ranges (and simplify some).
10170 * ch-except.c: Make sure an end_label is generated,
10171 and jump to it if there is no exception.
10173 * ch-convert.c (convert_to_reference): Strip off NOP_EXPR casts.
10174 * expr.c (expand_expr): Handle NOP_EXPR as Chill-style casts.
10175 (Need cleaning up and FSF installation!)
10176 * ch-parse.y: If taking the address of a cast, move the
10177 ADDR_EXPR inside the NOP_EXPR.
10179 * ch-typeck.c (my_build_array_ref): Simplified, more suitable
10180 versions of build_array_ref from c-decl.c. (E.g. don't barf
10181 if index type is char or bool.)
10182 * ch-typeck.c (build_chill_array_ref): Use my_build_array-ref.
10184 * ch-typech.c (build_chill_bin_type): New function.
10185 Support BIN(N) range type specification.
10186 * ch-parse.y (mode2), ch-lex.l: Recognize BIN(N).
10188 * ch-tree.h (CH_SIMILAR): Redefine in terms of chill_similar.
10189 * ch-typeck.c (chill_similar): New function. Recognize that
10190 that range types are similar to their parent types.
10192 * ch-tree.h: Declare flag_local_loop_counter.
10193 * ch-loop.c: Whether the loop variable is local to the loop
10194 in now controlled by flag_local_loop_counter, instead of
10195 #ifdef'd on CREATE_SCOPE.
10196 * ch-actions.c (lang_decode_option): Recognize flags
10197 "-f[no-]local-loop-counter".
10198 * toplev.c (lang_options): Add Chill flags -f[no-]local-loop-counter.
10200 * varasm.c (make_function_rtl): Due to problems with forward
10201 references, don't rename nested functions in Chill. (Kudge!)
10203 Sun Mar 28 10:12:45 1993 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10205 * ch-lex.l (push_back, readstring): Fix prototypes.

10215 * ch-lex.l (convert_charliteral): Rewrite to avoid bogus error msg.
10216 * ch-parse.y (get_type_of): Add function to deal with possible fwd
10217 declared type name. Call it from lotsa places. Add lotsa checks

10224 * ch-parse.y (action): Add recognition for allocate_memory and
10225 allocate_global_memory system calls.
10226 (mode2): Remove ill-conceived error check that broke REFs to
10227 as-yet-undeclared types. Check for IDENTIFIER_NODE, lookup its
10228 DECL if there, pass TREE_TYPE of decl to build_pointer_type.
10229 (variantfields, varianthack): Clean up.
10230 (variantfield): Check for IDENTIFIER_NODE, lookup its DECL if
10231 there, pass TREE_TYPE of decl to grok_fixedfields.
10232 (labellist): Explicitly assign error_mark_node to signal error.
10233 * ch-typeck.c (chill_compatible): Report FALSE for bad parameters,
10234 rather than seg faulting.
10236 Thu Mar 25 10:35:58 1993 Bill Cox (bill@rtl.cygnus.com)
10238 * ch-actions.c (lang_init): build_function_type for allocate_memory

10259 code-generation.
10260 * ch-expr.c (chill_expand_array_assignment): Generate the CONCAT_EXPR
10261 code.

10266 array and its type get on the permanent obstack.
10267 * ch-grant.c (write_grant_file): Don't write the _INIT=name
10268 specifier: It isn't needed, and loses (because of funny

10271 * ch-lang.c (finish_chill_enum): Don't allocate a dummy
10272 TYPE_DECL for the enum. I don't think it is needed (?),

10289 after each statement. Move convert call into
10290 chill_expand_assignment from ch-parse.y.
10291 * ch-grant.c: Generally re-order, clean up. Include Per's decode_mode
10292 simplification. Include commented-out hack in decode_mode to return

10311 vents seg fault when only WITH operand is invalid.
10312 * ch-parse.y (label_spec): Correct assignment within IF expression which
10313 was intended to be equality test. Remove unused variables.
10314 * ch-tree.h: Add prototype. Remove unused EXCP_CODE enumeration, and
10315 prototyping editorial comments.
10316 * ch-typeck.c: Disable generation of code to validate array index for
10317 now. Should be done as a call-back from more generic array_ref code.
10318 Clean up parameter checking. Remove unused variables.
10320 Fri Mar 12 11:57:32 1993 Bill Cox (bill@rtl.cygnus.com)

10405 where modeb is undefined.
10407 Tue Mar 2 20:16:37 1993 Bill Cox (bill@rtl.cygnus.com)
10409 * ch-actions.c: Add builtin function descriptions for memset and
10410 bitsetpowerset. Allow build_chill_num expression to exceed 16 bits,
10411 but not 32.

10418 * c-decl.c (init_decl_processing): Disable creation of C-specific
10419 builtin functions. They pollute the CHILL name space.
10420 * stor-layout.c (variable_size): Allow variable-size objects at file
10421 scope, for CHILL.
10423 Fri Feb 26 07:14:34 1993 Bill Cox (bill@rtl.cygnus.com)

10426 error for CHILL
10427 * ch-actions.c: Call build_temporary_variable, fix build_tree_list
10428 call in build_chill_cause_exception.
10429 * ch-convert.c, ch-expr.c: Use tree_cons to build list's last entry
10430 * ch-loop.c (build_temporary_variable): New function
10431 * ch-process.c: Call build_temporary_variable, spell start_process
10432 correctly.
10433 * ch-tree.h: Extern for build_temporary_variable
10435 Thu Feb 25 12:09:01 1993 Bill Cox (bill@rtl.cygnus.com)
10437 * c-decl.c (init_decl_processing): Disable initial creation of C-specific
10438 builtins - they pollute the CHILL name space.
10439 * ch-typeck.c (valid_array_index): Correct upper-bound check.
10440 * expr.c (expand_expr): Use actual library name for __inpowerset
10441 builtin.
10442 * stor-layout.c (variable_size): Disable complaint about variable-
10443 size type or decl at file scope. Perhaps later this s.b. a warning.

10445 (output_constant): Call new emit_set_data function for VAR_DECLs,
10446 in addition to CONSTRUCTORs.

10450 * ch-actions.c: Change all builtin functions names to their
10451 actual library names. Change references to boolean_type_node
10452 to references to the TREE_CODE == BOOLEAN_TYPE, to follow the
10453 convention.
10454 build_set_expr: Remove length parameter, call powersetlen() instead.
10455 remove handling of CHAR arrays - they're handled in build_char_array_expr.
10456 Call __eqpowerset to test for equality - we can't use a byte-length -
10457 need bitcount instead.
10458 build_chill_compound_expr, internal_build_compound_expr: Copy from C
10459 version that does stuff we don't want.
10460 build_binary_op: Check for in_size_in_bytes return < 0, indicating
10461 size is changeable at run time. Build two memcpy calls to implement
10462 string concatenation.
10463 powersetlen: Add function.
10464 build_chill_card: Call powersetlen.
10465 build_chill_max_min: Common code for powerset max/min.
10466 build_chill_length: Move VARYING array handling before regular char
10467 array handling.
10468 * ch-expr.c chill_expand_expr: Disable concatenate code - we need to
10469 the VARYING status of the target to do this correctly. Use powersetlen
10470 for the powerset operations, not a byte length.
10471 * ch-loop.c: Make CREATE_SCOPE #define to enable creation of a new scope
10472 for each CHILL loop, as Z.200 requires. Add powerset and error flags
10473 to loop structure. Evaluate user's powerset expression into a temp,
10474 scan it destructively with __ffsetclrpowerset or __flsetclrpowerset
10475 for powerset loop. Only do loop-end assignments if NOT a powerset
10476 loop, which has much less overhead now.
10477 * ch-tree.h: Add prototype for powersetlen.

10490 we are going to return 0.
10492 * ch-convert.c (convert_to_reference): Don't use
10493 TYPE_MAIN_VARIANT, because REFTYPE's type may be a newmode
10494 (which must match the type of the expr).
10496 * ch-grant.c (chill_seize): Don't let a type be copied just
10497 because we are seizing it.
10499 * ch-lang.c (finish_chill_enum): Convert TYPE_MIN_VALUE and
10500 TYPE_MAX_VALUE to integer type.
10502 * ch-loop.c (begin_for_range): Set lp->iter_type based on the
10503 tree type of the bounds.
10504 (build_loop_top): type of GE_EXPR and LE_EXPR is
10505 boolean_type_node, not lp->iter_type.
10506 (for_location): Ditto.
10508 * ch-action.c (build_chill_lower,build_chill_upper): Handle
10509 ENUMERAL_TYPE. Also, handle different kinds of arguments more

10513 match the type of modename.
10515 * ch-grant.c (chill_seize_aggr): Search also through anonymous
10516 types.
10518 * ch-grant.c (chill_seize): Check to see if SEIZEITEM has
10519 already been seized, and if so, do nothing.
10521 * c-typeck.c (process_init_constructor): If DEFAULT_VALUE
10522 comes out error_mark_node, set ERRONEOUS.
10524 * ch-actions.c (build_chill_binary_op_1): If EXP is NULL_TREE,
10525 don't use it.
10527 * ch-action.c (chill_comptypes): Test for structural
10528 equivalence of enums.
10530 * ch-typeck.c (build_chill_array_ref): Convert INDEX to
10531 TYPE_MIN_VALUE of DOMAIN if the types are compatible.
10533 * ch-grant.c (chill_seize): If DECLS is a TYPE_DECL for an
10534 ARRAY_TYPE, seize the domain type if its a set.
10536 Thu Feb 18 20:02:15 1993 Per Bothner (bothner@rtl.cygnus.com)
10538 * c-typeck.c (process_init_constructor): Emit error if some
10539 array elements are not initialized.

10595 * ch-convert.c (convert): Slightly more correct conversion
10596 for ARRAY_TYPEs (return as OK if CH_COMPATIBLE).
10597 * ch-expr.c (chill_expand_array_assignment): Invoke
10598 __builtin_memcpy using build_function_call, not directly at
10599 the rtx level (which doesn't work).

10615 * ch-decl.c (grok_chill_variantdefs): Really implement variant
10616 records for CHILL.
10617 * ch-grant.c (get_tag_value): New function.
10618 * ch-grant.c (decode_mode): Grant variant records.
10620 * ch-grant.c (chill_seize): If we seize a set, seize the set
10621 values.

10649 special-case support for a BIT_FIELD_REF in right-hand-side.
10650 * ch-lang.c (finish_chill_enum): Patch up enum elements to
10651 have the correct type (instead of integers, as in C).
10653 * ch-lex.l, ch-parse.y: Add disgusting hack (involving
10654 context-dependent look-ahead) so we can parse exception
10655 handlers correctly.
10656 * c-typeck.c (digest_init): Set output type for SET_TYPEs.
10657 * varasm.c (unpack_set_constructor): Add support for

10694 * ch-lex.l (convert_bitstring), Changed SET_TYPE_CONSTRUCTOR to
10695 take a list of elements which are in the set. This corresponds
10696 better to the tuple input form in Chill (and Pascal).

10698 New functions, to expand SET_TYPE CONSTRUCTORs.
10699 * varasm.c (output_constructor): Use pack_set_constructor
10700 to assemble a SET_TYPE constant from a CONSTRUCTOR.
10702 * ch-grant.c (decode_constant): Better grant for strings,
10703 enumeral, and bitstring constants.
10704 * ch-grant.c: Fixes in seize to avoid duplicates, and emit
10705 things in the correct order.
10706 * c-typeck.c (chill_initializer_constant_valid_p): Kludge
10707 needed to export a static function.
10708 * ch-typeck.c (convert): Avoid needlessly (and lossingly) calling
10709 chill_expand_tuple to convert fix string to varying.
10710 * ch-actions.c (build_chill_binary_op): Promote short
10711 integer operands if needed (otherwise emit routines barf).
10712 * ch-tree.h (SET_WORD_SIZE): New macro.
10713 * ch-parse.y: Fix syntax for RECEIVE CASE.
10714 * ch-parse.y (location): If IDENTIFIER is a CONST_DECL

10734 * ch-expr.c, ch-loop.c, ch-process.c, ch-tree.c, ch-typeck.c: change
10735 most integer_type_node references to chill_integer_type_node.

10739 * ch-except.c: New file. Stuff for exception handling.
10740 * ch-parse.y: Add working exception handling support.
10741 * ch-lex.l, ch-parse.y: Prefer standard type terminology
10742 (BOOLS, CHARS) even though non-standard (BITS, CHAR) is ok.
10743 * ch-grant.c: Fix various problems related to granting
10744 types such as bitsets.
10745 * ch-tree.c (build_bitstring_type): Set TYPE_MIN_VALUE
10746 to distinguish bitstrings from powersets (in the same way
10747 we distinguish char strings from char arrays).
10748 * ch-tree.h: New macro CH_BOOL_TYPE_P.
10749 * ch-tree.h, ch-actions.c (lang_init), ch-grant.c (decode_mode):
10750 Undo kludge where integer_type_node was hardwired to 16 bits.
10751 Make integer_type_node etc have the same size as in cc1.
10752 New types chill_integer_type_node and chill_unsigned_type_node
10753 that correspond to the Chill source types INT and UINT.
10754 For now, these match the C 'short' types, but that should
10755 become a configuration option later,
10757 Tue Feb 9 11:41:25 1993 Bill Cox (bill@rtl.cygnus.com)
10759 * ch-actions.c (build_chill_unary_op): allow NOT of a set.
10761 Tue Feb 9 08:27:18 1993 Bill Cox (bill@rtl.cygnus.com)

10764 too many/few actual parameters (and avoid seg fault).
10765 * ch-decl.c (do_decls): code cleanup for readability.
10766 * ch-loop.c (begin_chill_loop, end_chill_loop): remove
10767 emit_nop() calls - they now (since exceptions) cause seg faults.
10768 Make derogation on poor CHILL compiler non-specific.
10769 * ch-parse.y (mode2): enable VARYING keyword in CHAR(expr).
10770 * ch-tree.h: remove prototypes added to c-tree.h.
10771 * ch-typeck.c (build_chill_array_ref): correct getting domain
10772 subtree for a PARM_DECL. Subscripting a SET_TYPE is turned into
10773 an IN_EXPR.
10775 Sun Feb 7 18:20:49 1993 Bill Cox (bill@rtl.cygnus.com)
10777 * ch-tree.def: add a new tree type - just for varying array
10778 references. We were using ARRAY_REF, but the underlying C
10779 code also generates that one.
10780 * ch-convert.c, ch-expr.c, ch-typeck.c: use the new tree type.
10782 Sun Feb 7 17:33:17 1993 Bill Cox (bill@rtl.cygnus.com)
10784 * ch-convert.c: test given type against type of expr before
10785 calling chill_expand_tuple. We were getting lots of spurious
10786 calls...

10790 * cccp.c: Merge in various Chill-specific changes.
10791 * gcc.c (default_compilers array): Pass -lang-chill
10792 to cpp, not -lang-ch.

10796 * Makefile.in (install-libchill, install-librmt): Removed.
10797 * ch-actions.c (build_chill_exception_decl): Change decl
10798 to initialized char array, rather than unitialized common.
10799 (Simplifies extracting string name of exception.)
10800 * ch-actions.c: Adjust interface to cause_exception accordingly.
10801 * ch-typeck.c (build_chill_array_ref): Cause rangefail if
10802 index > limit, not >= limit.

10805 formal parameter.
10806 * ch-decl.c (do_decls): Allow (again) general initializer exprs.
10807 * ch-parse.y (call): Test for function call needs to test for
10808 FUNCTION_TYPE, not FUNCTION_DECL.
10809 nreverse arg list to build_chill_array_ref.
10810 * ch-typeck.c (build_chill_array_ref): Do recursive call at end
10811 and only if multiple indexes.
10812 * ch-typeck.c: Cleanups.

10817 * ch-loop.c (begin_for_range): correct interface to expand_start_cond
10818 and build_binary_op.
10819 * ch-tree.h: lots more prototypes

10821 * ch-typeck.c (chill_expand_tuple): handle set initializations better.
10823 Thu Jan 28 17:41:58 1993 Per Bothner (bothner@rtl.cygnus.com)
10825 * ch-grant.c (set_default_grant_file): Change default.
10826 Normally, grant file should end up in cwd.
10827 * ch-lang.c (build_chill_struct_type): Call pushtag,
10828 for the sake of debugging.
10829 * ch-lex.l: Improve comment parsing.
10830 * ch-lex.l (readstring): Some improvements.
10831 Initial support for control sequences in string literals.a

11010 chill front end to distinquish between true string types and
11011 arrays of char, since it uses ARRAY_TYPE for both, rather than
11012 trying to use the existing support for STRING_TYPE.

11058 index validation.

11074 * chill.gperf, ch-hash.h: add Wilfried's tokens
11075 * ch-lex.l: fold in Wilfried's changes. Some tokens

11090 * expmed.c (store_bit_field, extract_field_field): Undo
11091 yesterday's removal of MEM_IN_STRUCT_P "sanity test".
11093 * ch-decl.c (do_decls): Put back support for initializing.
11094 (Was accidentally removed in Jan 8 change.)

11190 use the same mechanism used for C++ static constructors.
11191 * ch-grant.c (chill_start_module_code): Make sure the
11192 init_name starts with the magic string also used for C++
11193 initializers. Also, don't embed the file name in the name,

11195 * ch-grant.c (chill_finish_module_code): Now that the
11196 initializer name follows the standard 'collect' convention,
11197 don't need to call assembler_constructor_alias, but can

11199 * varasm.c (assemble_constructor_alias): Remove no-longer-
11200 needed function.
11201 * ch-parse.y: Move code that is common to the beginning of

11205 before emit_line_note(), not after.
11207 Mon Jan 4 11:43:12 1993 Bill Cox (bill@cygnus.com)

11244 * ch-hash.h, chill.gperf: cleanup. fewer keywords seen by ch-parse.y.
11246 Sat Jan 2 13:27:49 1993 Per Bothner (bothner@rtl.cygnus.com)
11248 * ch-lex.l (check_newline): Use the orginal versions (derived
11249 from the C code, not the simplified, special-case version).
11250 Also, fix that version of check_newline to not call yylex()
11251 recursively.
11252 * ch-lex.l (yy_input): Call check_newline to handle
11253 newlines and check for # directives.
11254 * ch-lex.l (syntax): Don't recognize #-directives; these
11255 are now handled by check_newline.
11256 * ch-actions.c (lang_init): Call the modified version of
11257 check_newline(). Do this at the *after* we've initialized
11258 standard types, so this can be done while lineno is still 0.

11267 names for exceptions
11269 Fri Jan 1 12:30:31 1993 Fred Fish (fnf@cygnus.com)
11271 * ch-tree.h (JOINER): Define joiner character the same way
11272 C++ defines it.
11273 * ch-grant.c (chill_start_module_code): Use JOINER character
11274 to implement name mangling for the initializer function name.
11275 Algorithm is designed to be simple, distinct from C++ mangled
11276 symbols, and easy to convert to demangled form.
11278 Thu Dec 31 10:30:51 1992 Bill Cox (bill@rtl.cygnus.com)
11280 * ch-expr.c: make array assignments work with indirect refs.

11286 * ch-lex.l (yy_input): Re-write to return more than one
11287 character at a time (execpt when reading seize-files).
11288 Don't increment lineno until we start reading the next line.
11289 This fixes some off-by-one errors in lineno.
11291 Wed Dec 30 16:15:23 1992 Per Bothner (bothner@rtl.cygnus.com)
11293 * ch-convert.c: Assume use of new common.c.
11294 * ch-convert.c (convert_to_reference, convert_from_reference):
11295 New routines, to handle loc-identity declared variables and
11296 LOC parameters (both of which are implemented as references).
11297 * ch-lang.c (convert_to_boolean, convert_to_char): Move to
11298 ch-convert.c, where they would seem to belong.
11299 * ch-convert.c (convert): New function, since we no longer
11300 link in c-convert.c.
11301 * ch-expr.c (chill_expand_assignment): Handle by calling
11302 convert() instead of chill_comptypes().
11303 Also handle the LHS being a reference.
11304 * ch-parse.y: Add a procedure call as an action.
11305 * ch-parse.y (locdec, optlocinit): Move handling of
11306 loc-identity declarations from optlocinit to locdec
11307 - and add working semantics for it.
11308 * ch-parse.y (seizestatement, visibilty_stmt): Simplify.
11309 * ch-parse.y (grantstatement etc): Don't bother making list.
11310 * ch-lex.l: #include <sys/types.h> before <sys/stat.h>.

11314 * ch-parse.y, ch-expr.c: add support for declaring & assigning
11315 VARYING arrays.
11316 * ch-typeck.c: allow VARYING structures in assign_type_to_expr.
11318 Tue Dec 29 15:28:48 1992 Bill Cox (bill@cygnus.com)
11320 * ch-actions.c: implement expressions of arrays of char,
11321 ( concatenation, relationals ), correct type of code parameters
11322 * ch-expr.c: correct type of code parameters
11324 Tue Dec 29 11:16:19 1992 Bill Cox (bill@cygnus.com)
11326 * ch-decl.c: cleanup.
11327 * ch-parse.y: put emit_line_note() calls in lotsa places,
11328 per Fred's request; be sure that statements get counted also.
11329 * ch-lex.l: standardize function headers.
11331 Tue Dec 29 10:41:56 1992 Fred Fish (fnf@cygnus.com)
11333 * ch-decl.c (start_chill_function): Always return 1, rather
11334 than a random value.
11335 * ch-lex.l (check_newline): Add a version for chill that
11336 just snarfs the right value for main_input_filename out of
11337 the first line of the input file, without disturbing the
11338 lexer state or requiring it's assistance.
11339 * ch-actions.c (lang_init): Call check_newline, like the
11340 other language frontends, to get main_input_filename set
11341 from first line of input file.
11343 Mon Dec 28 18:49:01 1992 Bill Cox (bill@cygnus.com)
11345 * ch-parse.y: clean up conflicts. The remaining one is
11346 harmless.
11348 Mon Dec 28 17:28:40 1992 Bill Cox (bill@cygnus.com)
11350 * ch-parse.y, ch-lex.l, ch-actions.c: add stubs for I/O,
11351 clean up some parser conflicts.
11353 Mon Dec 28 15:00:20 1992 Bill Cox (bill@cygnus.com)
11355 * ch-parse.y, ch-lex.l: add keywords and parsing for most of
11356 CHILL I/O
11358 Sat Dec 26 20:48:23 1992 Fred Fish (fnf@cygnus.com)
11360 * chillrt/chillrt0.c: Oops, SVR4 doesn't need leading '_'
11361 on build_exceptions.
11363 Sat Dec 26 11:00:36 1992 Fred Fish (fnf@cygnus.com)
11365 * ch-grant.c (chill_finish_module_code): Call
11366 assemble_constructor_alias rather than assemble_constructor.
11367 * varasm.c (assemble_constructor_alias): New function,
11368 like assemble_constructor, but also handles the case where
11369 ASM_OUTPUT_CONSTRUCTOR is not defined and GNU ld is not
11370 being used. Emits a symbol table alias name with the correct
11371 prefix for collect to find and add to the __CTOR_LIST__.
11372 * chillrt/chillrt0.c: Build on previous hack that gets
11373 _build_exceptions into the __CTOR_LIST__, to make it work
11374 for both the non GNU-ld case and for the SVR4 case.
11376 Tue Dec 22 18:24:55 1992 Bill Cox (bill@cygnus.com)
11378 * ch-loop.c: clean up location enumeration - one more
11379 pass to do.
11381 Tue Dec 22 16:31:48 1992 Bill Cox (bill@cygnus.com)
11383 * ch-loop.c: Working version of location enumeration loop
11385 Tue Dec 22 14:42:14 1992 Bill Cox (bill@cygnus.com)
11387 * ch-lex.l: readability cleanup

11392 ch-loop.c: rough draft of location enumeration
11393 ch-lex.l, ch-expr.c, ch-decl.c: minor cleanup
11394 ch-actions.c: finish making pred() and succ() work.
11396 Mon Dec 21 10:04:35 1992 Bill Cox (bill@cygnus.com)
11398 * ch-actions.c: allow pred(char) and succ(char).
11400 Sun Dec 20 16:04:28 1992 Bill Cox (bill@cygnus.com)
11402 * ch-expr.c, ch-actions.c, ch-parse.y, ch-loop.c,
11403 c-expr.c: make DO WITH work.
11405 Sun Dec 20 12:22:53 1992 Bill Cox (bill@cygnus.com)
11407 * ch-loop.c, ch-actions.c, ch-typeck.c: powerset loops
11408 now work
11410 Sat Dec 19 14:20:23 1992 Per Bothner (bothner@cygnus.com)
11412 * c-typeck.c (process_init_constructor): Add warning if
11413 there is a duplicate default initializer element.
11414 * ch-typeck.c (chill_give_type_to_expr): New function,
11415 to handle coercion of an expression to context-given type,
11416 Takes care of untyped tuples, and case expressions.
11417 * ch-decl.c (do_decls), ch-typeck.c (chill_expand_return,
11418 chill_expand_result), ch-parse.y <assignaction>:
11419 Use chill_give_type_to_expr().
11420 * ch-typeck.c (chill_handle_case_label): New parameter list,
11421 to handle the (new) conventions for <case_label>, including
11422 default elements and ranges.
11423 * ch-parse.y <expanded_case_label>, ch-typeck.c
11424 (expand_case_expr): Use new version of chill_handle_case_label.
11425 * ch-decl.c (push_syndecls): Change parameters: Instead of
11426 TREE_LIST representing a compete <synonym definition statement>,
11427 just pass the parts of a single <synonym definition> as 3
11428 different parameters. Also, use chill_give_type_to_expr(),
11429 to handle untyped tuples in the RHS.
11430 * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct
11431 a tree - just call push_syndecls() on each <synonum_definition>
11432 as we see it.
11433 * ch-parse.y (exprlist_get_single): Remove; no longer needed.
11434 * ch-parse.y: Handle <tuple> without mode name diferently from
11435 <tuple> with mode name. The latter is a <primval> that can be
11436 in most contexts, but if the <mode name> is missing, the <tuple>
11437 is only allowed in certain contexts. Use the new non-terminal
11438 <untyped_expr> to indicate those contexts where untyped tuples
11439 (and case expressions) are valid because the expression gets a
11440 type from its context (such as the RHS of an assignment).
11441 Use chill_give_type_to_expr in those contexts.
11443 Sat Dec 19 14:01:26 1992 Bill Cox (bill@cygnus.com)
11445 * ch-actions.c, ch-loop.c, Makefile.in: looping stuff.
11447 Sat Dec 19 10:16:20 1992 Bill Cox (bill@cygnus.com)
11449 * ch-parse.y: clean up warning messages from byacc. bison
11450 still complains thrice.
11452 Fri Dec 18 12:33:29 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11454 * ch-actions.c (maybe_chill_comptypes): Delete unused
11455 function.
11456 (chill_comptypes): Add new parameter ERRSTR. All callers
11457 changed.
11458 (build_chill_binary_op): Fix indentation to match GNU coding
11459 style.
11461 Fri Dec 18 08:18:13 1992 Bill Cox (bill@rtl.cygnus.com)
11463 * ch-parse.y, ch-expr.c, ch-actions.c, expr.c: major

11473 a default initializer element.
11474 * ch-parse.y: Implement default elements for tuples
11475 (as in '(else):' and '(*):' ).
11477 * ch-parse.y: Previous change to dis-ambiguate case-labels
11478 seems to have allowed getting rid of all of the expr_or_list hair.
11479 * ch-decl.c (do_decls): Undo Tiemann's change to "Handle
11480 initialization of multiple variables by a tuple" - the
11481 idea is bogus.
11483 Wed Dec 16 11:17:53 1992 Bill Cox (bill@cygnus.com)
11485 * ch-parse.y: complete re-write of DO statement handling.
11486 now operational, except WITH is stubbed out. Improved
11487 syntax error message.
11488 * ch-actions.c: DO support: high_domain_value(), low_domain_value ().
11489 * ch-expr.c: fixes to IN_EXPR handling.
11491 Tue Dec 15 17:15:13 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11493 * ch-grant.c: Add casts to alloca return to avoid compiler warning.
11494 * ch-lex.c: Likewise.
11496 * Makefile.in (ch-lex.c): Delete incorrect free declaration added
11497 by flex to avoid compiler error.
11499 Tue Dec 15 08:41:08 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11501 * ch-decl.c (do_decls): Handle initialization of multiple
11502 variables by a tuple.
11504 * ch-decl.c (do_decls,start_chill_function): Make DECL public
11505 if we're doing a GRANT ALL at top level.
11507 * ch-lang.c (build_range_type): Deal with typecast to CHAR in
11508 range expression.
11510 * c-typeck.c (digest_init): SET_TYPE is not a scalar type.
11511 BOOLEAN_TYPE and CHAR_TYPE are scalar types.
11513 Mon Dec 14 14:58:32 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11515 * ch-lex.l (get_chill_{linenumber,filename}): New functions.
11516 (convert_number): Use LONG_TYPE_NODE instead of INTEGER_TYPE_NODE.
11518 Mon Dec 14 13:36:44 1992 Bill Cox (bill@cygnus.com)
11520 * expr.c: install and test newer Pascal IN_EXPR code,
11521 but don't activate it - it's very verbose.
11523 Mon Dec 14 00:22:49 1992 Fred Fish (fnf@cygnus.com)
11525 * Makefile.in (LANGUAGES): Add chill.

11532 sublibchill.a, ch-parse.o, ch-parse.c ch-*.o, install-libchill,
11533 install-librmt): New targets.

11541 Sun Dec 13 14:07:32 1992 Bill Cox (bill@cygnus.com)
11543 * ch-actions.c: fix unary operations, modulus ops,
11544 (discovered after extending regression tests).
11546 Sun Dec 13 12:16:32 1992 Bill Cox (bill@cygnus.com)
11548 * resync with Michael and Wilfried
11550 Sun Dec 13 09:11:25 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11552 * ch-parse.y (output_constant): Fixed some whitespace
11553 problems.
11554 * ch-tree.h: Add declarations for new chill functions that
11555 have been implemented but not (yet) declared.
11557 Sat Dec 12 00:17:23 1992 Per Bothner (bothner@cygnus.com)
11559 * c-typeck.c (process_init_constructor): Warn about duplicate
11560 labels for labelled initializer elements.
11561 * ch-lex.l (various operator tokens, such as "+"): Don't
11562 set yylval.code to a TREE_CODE; this is better done in parser.
11563 * ch-parse.y: Some work with case labels and tuples.
11564 Get literal range as tuple (and case) labels working.
11565 Fix some problems introduced by recent grammar overhaul.
11567 Fri Dec 11 13:28:48 1992 Bill Cox (bill@cygnus.com)
11569 * ch-actions.c, ch-parse.y ch-tree.h ch-expr.c, ch-typeck.c:
11570 got long, real expressions working. We can also call a func-
11571 tion and use its return value.
11573 Thu Dec 10 14:45:17 1992 Per Bothner (bothner@cygnus.com)
11575 * ch-parse.y: Major change to remove or at least identify
11576 parser ambiguities. One result: We now allow actions that
11577 start with '(', as required by teh Blue Book. This does break
11578 some things; look for FIXME for things that need work.
11579 * ch-typeck.c (chill_expand_case_expr): We need an extra
11580 level of looping to (in the future) support <case label
11581 specification>s with more than one <case label list>.
11583 Thu Dec 10 09:21:41 1992 Bill Cox (bill@cygnus.com)
11585 * ch-actions.c, ch-expr.c: Implement string assignments
11586 and relationals.

11594 * ch-parse.y, ch-actions.c, ch-expr.c: redo type checking.
11595 regression test and fix bit arrays and set ops.
11597 Mon Dec 7 14:57:46 1992 Bill Cox (bill@cygnus.com)
11599 * ch-actions.c: implement crude relationals between
11600 non-exotic operands, such as integers.
11602 Mon Dec 7 10:42:35 1992 Bill Cox (bill@cygnus.com)
11604 * ch-actions.c: implement relational, logic operations
11605 on arrays of BOOLs.
11607 Mon Dec 7 08:55:20 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11609 * ch-actions.c (lang_init): Set LINENO to 1 at beginning to
11610 indicate we are done with initialization.
11612 * ch-decl.c (do_decls): Set TREE_PUBLIC if we are doing a
11613 `grant all'.
11614 (start_chill_function): Ditto.
11616 * ch-lex.c (convert_bitstring): Set TREE_CONSTANT.
11617 (compiler_directive): Don't confuse compiler directives with
11618 equality comparison operators.

11631 Fri Dec 4 13:54:58 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
11633 * tree.def: Move CARD_EXPR and SET_LE_EXPR back down with the other
11634 Pascal-required ones, since C++ no longer needs them. When
11635 Chill's public, a comment can be added to the effect that
11636 SET_LE_EXPR is also used by Chill.
11638 Fri Dec 4 12:05:01 1992 Bill Cox (bill@cygnus.com)
11640 * Restore CARD_EXPR and SET_LE_EXPR to tree.def.

11679 (push_newmode,push_synmode): Call `fixup_unknown_type' when we
11680 see a declaration that uses `unknown_type_node'. FIXME.
11682 * ch-grant.c (decode_constant): New function.
11683 (decode_decl): Call `decode_constant' for CONST_DECLs.
11685 * ch-lex.l (char action): Use ridpointers instead of
11686 lookup_name to get "char"'s declaration.
11688 * ch-parse.y: Call `build_lang_decl' instead of `build_decl'
11689 when we need to build a TYPE_DECL.
11691 Tue Dec 2 09:44:05 1992 Bill Cox (bill@cygnus.com)
11693 * ch-typeck.c: clean up a gcc warning with a forward
11694 declaration of build_string_type.
11696 Tue Dec 1 16:51:05 1992 Bill Cox (bill@cygnus.com)
11698 * ch-actions.c: completely remove those builtin calls
11699 that are duplicated in c-decl.c
11701 Tue Dec 1 16:38:51 1992 Fred Fish (fnf@cygnus.com)
11703 * ch-actions.c (lang_init): Ifdef out initializations for
11704 __builtin_abs and __builtin_fabs, since they are duplicates of
11705 initializations in c-decl.c, and trigger spurious warnings.
11707 Tue Dec 1 16:35:18 1992 Bill Cox (bill@cygnus.com)
11709 * ch-parse.y: make size() work with a typename argument.
11711 Tue Dec 1 16:15:56 1992 Bill Cox (bill@cygnus.com)
11713 * ch-parse.y, ch-lex.l, ch-actions.c: add builtin

11728 * dwarfout.c (output_compile_unit_die): Test language_string and
11729 set LANG_CHILL if appropriate.
11730 * ch-parse.y (language_string): New for chill.
11731 * chillrt: Renamed directory chill to chillrt.
11732 * chill: Renamed chillsh to chill.
11733 * Makefile.in: Adjust for renamings.
11734 * chillrt/Makefile: Adjust for directory renaming.
11736 Mon Nov 30 17:35:33 1992 Fred Fish (fnf@cygnus.com)
11738 * chillsh: New script frontend (ala g++), installed as "chill".
11739 Can't be called "chill.sh" because make tries to cat it into the
11740 "chill" directory. Can't be called just "chill" cause that's
11741 already there as a directory.
11742 * Makefile.in: Add rules to install chillsh as "chill".
11743 * chill/libchill.c: Temporarily ifdef out stuff that wants
11744 to conflict with i486/SVR4 runtime or wants to pull in librmt.a,
11745 which itself causes linkage to fail.
11747 Mon Nov 30 16:28:19 1992 Bill Cox (bill@cygnus.com)
11749 * ch-lex.l: added keywords for TRUNC, ROUND, FLOAT, LFLOAT
11750 conversion routines.
11751 * ch-parse.y: added %tokens for TRUNC, ROUND, FLOAT, LFLOAT.
11752 Added production for SIZE(expr).
11753 * ch-actions.c: Add semantic routine chill_sizeof ().
11755 Mon Nov 30 16:20:40 1992 Per Bothner (bothner@cygnus.com)
11757 * ch-lex.l, ch-parse.y: Translate token PFEIL into English ARROW.
11758 * ch-parse.y (op6): Remove handling of string repetition operator,
11759 until we can figure out a way to parse it correctly.
11760 * ch-parse.y (optmodename): New non-terminal.
11761 * ch-parse.y (tuple): Merge the two variants using optmodename.
11762 * ch-parse.y (location): Add semantic actions for
11763 dereferencing operator ->.
11765 Mon Nov 30 08:01:29 1992 Bill Cox (bill@cygnus.com)
11767 * ch-actions.c: removed compile warning, better code for abs.
11769 * ch-parse.y: add productions for builtin functions succ, pred,
11770 abs, and size. Add %tokens also. Sort %tokens alphabetically.
11772 * ch-lex.l: add parsing for builtin function names, such as abs,
11773 pred, succ, etc. Put flex -a option into Makefile.in, so we can
11774 clean up the lexer soon.
11776 Tue Nov 24 14:18:48 1992 Per Bothner (bothner@rtl.cygnus.com)
11778 * ch-typeck.c (chill_handle_case_label, chill_handle_case_default):
11779 New functions, for code common to CASE actions and expressions.
11780 * chill.y: Replace some code by calls to chill_handle_case_label
11781 and chill_handle_case_default.
11782 * ch-typeck.c (chill_expand_case_expr): Add semantics.
11784 * tree.c: Change doing_chill_thang from extern to common.
11786 Mon Nov 23 18:34:22 1992 Per Bothner (bothner@rtl.cygnus.com)
11788 * ch-tree.def: New CASE_EXPR type, for case expressions.
11789 * ch-expr.c (chill_expand_expr): Hook for CASE_EXPR.
11790 * ch-typeck.c (chill_expand_case_expr): New function.
11791 Placeholder to implement case expressions.
11792 * ch-typeck.c (chill_expand_result, chill_expand_return):
11793 Handle mode-unspecified tuples and case expressions in
11794 the context of RETURN and RESULT actions.
11795 * chill.y (assignaction): Handle case expressions in the
11796 context of the RHS of an assignment action.
11797 * chill.y (caseaction): Remove spurious duplicate OF in grammar.
11798 * chill.y: Handle labeled structure tuples.
11799 * chill.y: New rules to parse CASE expressions.
11800 * tree.c (build_function_types): Allow Chill functions
11801 to return arrays and functions.
11803 Wed Nov 18 13:50:28 1992 Per Bothner (bothner@rtl.cygnus.com)
11805 * ch-typeck.c (chill_expand_tuple): New function. Expand a
11806 tuple (constructor) given an expected (context) type.
11807 * chill.y: Implement 'LHS := TUPLE' using expand_chill_tuple,
11808 using the mode of the LHS and the expected type of the TUPLE.
11809 * chill.y: Implement initialization.
11810 * chill.y: Fix some syntax bugs (forbidlist must be surrounded
11811 by parentheses), and remove or note ambiguities.
11812 * chill.y: Started converting layout style to be like c-parse.in.
11813 * chill.y: Implement IF expressions.
11814 * chill.y: Added syntax rules for tuples. Labelled and unlabelled
11815 array tuples should now work (in some contexts).
11816 * ch-actions.c: Initialize doing_chill_thang to 1.
11817 * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
11818 initializer, to make pushdecl and finish_decl work.
11819 * c-decl.c (convert_for_assignment): If Chill, don't convert
11820 function and arrays into pointers. (Maybe functions should
11821 still be converted?)
11822 * c-typeck.c (grokdeclarator): Allow functions in Chill
11823 to return arrays and functions.
11825 Mon Nov 16 15:40:47 1992 Per Bothner (bothner@rtl.cygnus.com)
11827 * chill.y (exprlist_get_single): New function, used when
11828 parsing tuples.
11829 * chill.y: Re-did parsing of tuples to remove ambiguities.
11830 This was a bitch.
11832 Tue Nov 10 16:30:55 1992 Per Bothner (bothner@rtl.cygnus.com)
11834 * ch-typeck.c (chill_expand_result); Set TREE_SIDE_EFEFCTS
11835 flags on assignment to result.
11836 * ch-typeck.c (build_chill_array_ref): Subtract lower
11837 bound of domain if non-zero. Preliminary hook for range checking.
11838 * ch-tree.h, chill.l: Combine variables range_check and
11839 range_check_disabled into global variable range_checking.
11840 * ch-tree.h: Better definitions of CH_CLASS_IS_VALUE
11841 CH_CLASS_IS_DERIVED.
