2727 (PEEK_TOKEN): Now calls an optimized variant of peek_token_(0).
2728 (next_token_): Don't call peek_token_. Renamed to forward_token_.

2880 bit-string, bit_one_node and bit_zero_node were switched.

3009 Give up on trying to use the cleanup mechanism in stmt.c to
3010 make sure the exception handler get unlinked on goto/exit/return.

3074 * lex.l (readstring): Add processing of control sequence
3075 in character string literals. The granting mechanism writes

3095 the entrypoint of a process.
3096 (build_process_header): Change PROCESS arguments to be
3097 like arguments of a function. There will be a wrapper
3098 which is the real entry point for a PROCESS. This wrapper
3099 is automatically build after a PROCESS definition and gets
3100 as argument a pointer to a structure looking like the
3101 arguments of the PROCESS. This wrapper will call the
3102 PROCESS (see build_process_wrapper).
3103 (build_process_wrapper): New function (see above).
3104 (build_start_process): Change processing of arguments.
3105 (tasking_setup): Add processing of a different entry point

3134 * Makefile.in (GNUCHILL_VERSION): Remove it, its defined in
3137 * chill.in: In case of -fgrant-only pass "-S -o /dev/null"
3138 to the compiler to avoid generation of an object file.
3140 Thu Sep 8 12:07:28 1994 Per Bothner (bothner@kalessin.cygnus.com)
3142 * convert.c (display_int_cst), ch-tree.h: New function.
3143 * convert.c (digest_array_tuple): Use digest_int_cst to
3144 provide better error messages. Return error_mark_node on error.

3156 * except.c (finish_handler_array): Avoid calling C-specific kludge
3157 complete_array_type.
3159 * convert.c (digest_constructor): Rename, and re-write to:
3160 (digest_array_tuple, convert): No longer use the code in
3161 ../c-typeck.c; use a Chill-only implementation (sigh).
3163 * typeck.c (chill_expand_tuple): Remove unneeded call to
3164 complete_array_type.
3166 * expr.c (fold_set_expr), grant.c (decode_constant),
3167 typeck.c (expand_constant_to_buffer): Update name of called
3168 function unpack_set_constructor to get_set_constructor_bits.
3169 * expr.c (powersetlen ): Remove redundant call to convert.

3173 * inout.c (build_chill_writetext): Handle 64-bit integer literals
3174 by trying to convert them to a smaller type.
3176 * lex.l (convert_number): Always use long long type (possibly
3177 unsigned) to avoid problems with constant folding truncation.
3179 Mon Sep 5 08:08:22 1994 Wilfried Moser (moser@rtl.cygnus.com)
3181 * ch-tree.h (enum chill_built_in_function): Add BUILT_IN_QUEUE_LENGTH.

3194 getting rid of [f]lex.
3196 * lex.l (convert_number): Use mul_double and add_double.
3197 Set result type to a reasonable type in which the literal
3198 will fit. Give error message if literal is too big.
3200 * lex.l (equal_number): Switch (temporarily) to permanent obstack.
3202 * typeck.c (build_chill_slice_with_range): Check for empty
3203 slice *after* we have checked for upper/lower limit in range.
3205 * grant.c (decode_mode): Remove unused code. (BOOL and
3206 CHAR ranges are represented as INTEGER_TYPEs.)
3208 * tasking.c (build_process_header): Add missing call to
3209 expand_start_bindings.
3210 * parse.c (end_function): Add missing expand_end_bindings.
3212 Wed Aug 31 17:25:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3214 * decl.c (init_decl_processing): Set set_alignment.
3216 Tue Aug 30 16:40:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
3218 * actions.c (print_missing_cases, check_missing_cases,
3219 BITARRAY_TEST, BITARRAY_SET): New functions and macros,
3220 to check for completeness of case actions and expressions.
3221 * decl.c (c_decode_option, init_decl_processing):
3222 Don't set warn_switch.
3223 * expr.c (chill_expand_case_expr): Call check_missing_cases
3224 instead of check_for_full_enumeration_handling.
3225 * parse.c (parse_case_actions): Call check_missing_cases.
3227 * expr.c (build_chill_binary_op): Remove some dead code.
3228 * expr.c (chill_truthvalue_conversion): Call build_chill_binary_op
3229 instead of build_binary_op.
3230 * ch-tree.h (binary_op_error, build_binary_op): Unused. Removed.
3232 * parse.c (end_function): Use kept_level_p in parameter to
3233 poplevel. This reverts a June 13 change.
3235 Fri Aug 26 11:50:19 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3237 * configure: Ignore --without, as ../configure does.
3239 Wed Aug 24 01:17:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3241 * lex.l: Change rule for decimal numbers to allow identifiers
3242 to start with an underscore (_).

3246 * tasking.c (build_receive_signal_case_label): Remove backwards
3247 chill_convert_for_assignment (which converted whatever garbage
3248 was in the *target* to the type of the signal argument!).
3250 Fri Aug 19 07:10:43 1994 Wilfried Moser (moser@rtl.cygnus.com)
3252 * inout.c (build_chill_io_list_type, build_enum_tables),
3253 tasking.c (build_tasking_struct): Temporarily reset
3254 maximum_field_alignment to 0, so that the compiler-built
3255 data structures needed by the RTS can be independent of -fpack.
3257 Thu Aug 18 13:39:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3259 * typeck.c (build_init_struct): Temporarily reset
3260 maximum_field_alignment to 0, so that the compiler-built
3261 data structures needed by the RTS can be independent of -fpack.
3263 Wed Aug 17 23:48:33 1994 Wilfried Moser (moser@rtl.cygnus.com)
3265 * parse.c (parse_primval, expect, parse_on_exception_list):
3266 Print error message only in pass 2.

3270 * decl.c (switch_to_pass_2): Revert June 13 change,

3273 * ch-tree.def (SLICE_EXPR): New tree-code.
3274 * typeck.c (build_chill_slice): For building a slice of a
3275 bit-string, just generate a SLICE_EXPR.
3276 * decl.c (init_decl_processing): Declare __pscpy.
3277 * actions.c (chill_expand_assignment): Handle a SLICE_EXPR
3278 on the LHS of assignment, by calling __pscpy.
3279 * expr.c (chill_expand_expr): Handle SLICE_EXPR (as a RHS
3280 value) by using __psslice to copy slice to a temp.
3282 Wed Aug 17 05:52:44 1994 Wilfried Moser (moser@rtl.cygnus.com)
3284 * Make-lang.in: Change version of GNUCHILL compiler to 1.4.1.
3285 * expr.c (build_chill_length): Enable LENGTH built-in to process
3286 Buffers and Events too (Z.200/1992).
3287 * lex.l (yywrap): Always set yyin to finput and/or grt_in. On
3288 a linux system the previous version was not able to run.
3289 * tasking.c: Correct processing of infinite buffer- and event-length
3290 to avoid RANGEFAIL warning.
3292 Thu Aug 11 11:46:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3294 * parse.c (parse_if_expression_body): Don't call the C-specific
3295 build_conditional_expr. Just do build_nt (COND_EXPR, ...).
3296 * convert.c (convert): Convert a COND_EXPR by converting
3299 * convert.c (convert): Don't call convert before
3300 convert_to_reference. It's apt to do weird and unneedful things.
3301 * convert.c (convert): If the expression is varying, just call
3302 varying_to_slice, which simplifies quite a bit.
3304 * ch-tree.h (varying_to_slice): Add prototype.
3305 * typeck.c (varying_to_slice): Remove prototype.
3307 * satisfy.c (satisfy): Move case PAREN_EXPR from type 'e'
3310 * except.c (emit_setup_handler): Temporarily reset the
3311 maximum_field_alignment to zero so the compiler's exception
3312 data structures can be compatible with the run-time system,
3313 even when we're compiling with -fpack.
3315 * expr.c (compare_records): Call saved_if_needed on operands.
3317 * expr.c (build_set_expr case NE_EXPR): Don't use __nepowerset
3318 which has been reimplemented to just call __eqpowerset and
3319 invert the result. Inline this new implementation by
3320 handling as EQ_EXPR, and inverting the result.
3321 * decl.c (init_decl_processing): Don't define unused __eqpowerset.
3323 * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
3324 type boolean_type_node, not void_type_node. (Fixing this
3325 avoids a crash in the back-end.)
3327 * grant.c (decode_constant): In a CALL_EXPR, if the argument
3328 list is not a TREE_LIST (as in string repetiation), don't
3331 Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3333 * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
3334 CONST_DECL is from a SET definition. (This is safer than
3335 checking that the type is ENUMERAL_TYPE, because synonym
3336 definitions may have a NULL TREE_TYPE.)
3337 Also, if we have duplicate enums whose types are identical,
3339 * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
3340 an extra 'quiet' parameter, which is true if we're called from
3341 bind_sub_modules. (In that case an error message about duplicated
3342 decls would be repeated later, so suppress it.)
3344 * parse.c (stmt_count): Removed, not used.
3345 (INIT_ACTION): Call emit_line_note only if !ignoring.
3346 (parse_begin_end_block): Do INIT_ACTION even if ignoring.
3348 Fri Aug 5 12:39:11 1994 Per Bothner (bothner@kalessin.cygnus.com)
3350 * parse.c (parse_untyped_expr): Add missing semi-colon.

3354 * parse.c (parse_untyped_expr): Fix various problem for the
3355 case that we see a '(': Add missing 'case' keyword.
3356 Only recurse if '(' is followed by 'if', 'case' or '[',
3357 and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
3359 * parse.c (parse_send_action): Remove extra nreverse.
3361 Thu Jul 28 04:00:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3363 * expr.c (build_allocate_global_memory_call, build_allocate_memory_call):
3366 Tue Jul 26 22:48:15 1994 Michael Tiemann (tiemann@blues.cygnus.com)

3369 Added a missing call to `require' as well.
3371 Tue Jul 19 10:30:12 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3373 * lex.l (yywrap): Define as yywrap_chill to avoid conflicts with
3374 the extern declaration in the flex skeleton.
3376 Mon Jul 18 23:06:04 1994 Per Bothner (bothner@kalessin.cygnus.com)
3378 * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
3379 Check the type of the instance expr using CH_COMPATIBLE,
3380 and not just == instance_type_node. (This allows
3381 the expression to have mode READ INSTANCE).
3382 * tasking.c (build_instance_type): Give instance_type_node
3383 a non-null novelty (i.e. different from a struct).
3384 * tasking.c (build_receive_case_start, build_delay_case_start):
3385 Check that for a location using CH_LOCATION_P.
3387 Mon Jul 18 13:22:23 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
3389 * expr.c (finish_chill_unary_op): Use TREE_SET_CODE not TREE_CODE
3390 to modify a tree code.
3392 Mon Jul 18 11:24:57 1994 Bill Cox (bill@rtl.cygnus.com)
3394 * convert.c (digest_structure_tuple): Fix thinko in TREE_CODE
3397 Mon Jul 18 05:40:15 1994 Doug Evans (dje@canuck.cygnus.com)
3399 * decl.c (warn_bad_function_cast): Define so cc1chill will link.

3403 * parse.c (parse_send_action): Do tree_cons *before* checking
3406 Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3408 * convert.c (digest_structure_tuple): Don't use convert to
3409 coerce initial value, use chill_convert_for_assignment instead.
3410 (Thus we also get range_checking.)
3412 * expr.c (build_chill_card): Use force_addr_of instead of
3413 build_chill_addr_expr.
3415 * loop.c (build_temporary_variable): Stylistic tweak.
3416 * loop.c (maybe_make_for_temp): Initialize temp using
3417 explicitly, not using assignment. Avoids a problem if
3418 the expression is read-only.
3419 * typeck.c (smash_dummy_type): Always used the saved TYPE_NAME
3420 and CH_NOVELTY_FLAG.
3422 Wed Jul 6 20:12:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3424 * expr.c, ch-tree.h (finish_chill_unary_op): New function,
3425 based on code ripped out of build_chill_unary_op.
3426 (build_chill_unary_op): Call finish_chill_unary_op unless pass==1.

3433 build_chill_slice_with_length): Call save_if_neeed on array arg.
3434 * expr.c (varying_to_slice): Re-write to use save_if_needed.
3436 * typeck.c (extract_constant_from_buffer): Handle BOOLEAN_TYPE.
3438 Mon Jun 27 01:11:10 1994 Wilfried Moser (moser@rtl.cygnus.com)
3440 * inout.c (build_chill_io_list_type): Change layout of __tmp_WIO_list
3441 that it is always the same, regardless if compiled with -fpack
3444 Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3446 * lex.l (yywrap): Kludge to work around mis-synchronization
3447 between lexer (which read ahead) and parser: Don't emit
3448 (left-over) uze_seizefile directives at the end of file.
3450 * typeck.c (build_chill_array_ref): Allow the derived
3451 array indexing syntax for arrays of bit strings.
3452 Add a comment explaining why.
3454 * typeck.c, ch-tree.h (string_assignment_condition): Change
3455 the interface. Return a boolean expression (which can be
3456 used in a conditional at run-time); never expand anything.
3458 * actions.c (chill_convert_for_assignment): Check
3459 string_assignment_condition here, rather than in callers.
3460 * actions.c (chill_expand_assignment): Don't need to check
3461 string_assignment_condition here.
3462 * expr.c (build_chill_function_call): Likewise.
3463 * satisfy.c (safe_satisfy_decl): Update accordingly.
3464 * decl.c (do_decl): Simplify testing and conversion by
3465 deferring everything to chill_convert_for_assignment.
3467 * parse.c: Combine the two variables 'ignore_exprs' and
3468 'ignore_actions' into one variable called 'ignoring'.
3469 * ch-tree.h: Add 'extern int ignoring'.
3470 * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
3471 Rename ignore_actions and ignore_exprs to ignoring.
3472 Remove unneeded extern declarations.
3473 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3474 build_chill_arrow_expr, build_generalized_call, build_delay_action,
3475 build_buffer_type, build_event_type): I changed my mind. It is
3476 cleaner to check for 'ignoring' in the parser, rather than here.
3477 * parse.c (parse_action, parse_primval, parse_opt_mode):
3478 Therefore we must check for ignoring here.
3479 * parse.c (parse_loc_declaration): Set ignoring in pass 2
3480 when parsing the mode.
3482 * tasking.c (generate_tasking_code_variable): Do arithmetic
3483 on signal_code etc using unsigned rather than signed shorts.
3485 * grant.c (static char* current_grant_modename): Removed.
3486 * grant.c (decode_decl case CONST_DECL): Remove error message.
3488 * Make-lang.in (CHILL_SRCS): Add $(srcdir)/ch/parse.c.
3489 * Makefile.in: Fix dependencies for parse.o.
3490 Remove some duplicate dependencies for $(TREE_H).
3492 Mon Jun 13 14:25:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3494 * typeck.c (build_chill_cast): Allow a value cast between
3495 non-discrete object of the same size, but with a pedwarn.
3496 * typeck.c (bit_string_assignment_condition,
3497 char_string_assignment_condition): Merge near-duplicate functions
3498 and place the code in string_assignment_condition.
3500 * decl.c (parm_flag, declare_parm_level, in_param_level_p):
3502 * decl.c (start_chill_function, finish_chill_function): Make
3503 parameter level have same nesting level as body, as required by Z200.
3504 * decl.c (switch_to_pass_2): Always exit if an error has been found.
3505 * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
3506 generated from GRANT ALL.
3507 * decl.c (lookup_name_for_seizing): Don't seize from
3508 the nesting level of builtins (predefined objects).
3509 * decl.c (lookup_name_for_seizing): Make more robust on error.
3511 * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
3512 be 'RESULT' (or 'result'). This makes it more accessible from gdb.
3513 Also, use do_decl to declare it, so that debugging symbols are
3514 generated. And, re-arrange so that actions that need to
3515 be done both passes (such as push_levels) use the same code.
3517 * parse.c (get_type_of): If ignore_exprs, don't lookup name.
3518 * parse.c (end_function): Fix poplevel params.
3519 * parse.c (expect): Don't read forwards on an error.
3520 * parse.c (parse_field): Don't define two tag_list locals!
3521 * parse.c (parse_pass_1_2): Better error message.
3523 * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
3524 parse_opt_mode, rather than vice versa. If parse_opt_mode
3525 returns NULL_EXPR, then parse_mode gives an error.
3526 Change parse_opt_mode (and any functions it calls) to only
3527 return NULL_TREE if there is no mode (even on ignore_exprs).
3528 (parse_set_mode, parse_structure_mode, parse_procedure_mode):
3529 Never return NULL_EXPR.
3530 * tasking.c (build_buffer_type, build_event_type): Return
3531 void_type_node instead of NULL_EXPR if ignore_exprs is true.
3533 * parse.c (parse_synonym_definition): Call parse_untyped_expr
3534 only if we have a mode.
3535 * parse.c (parse_send_action): Parse list of untyped_expr's,
3536 rather than a list of (typed) expressions.
3537 * parse.c (parse_primval): Emit error if '[' seen without
3538 preceding mode name. (If this is to be allowed, call
3539 parse_untyped_expr instead.)
3541 * parse.c (parse_array_index): Renamed to ...
3542 (parse_index_mode): ... to match Z200 terminology.
3543 Re-write to resolve some of the nastier ambiguities,
3544 and allow things like ' CHAR(10) : CHAR(20) '.
3546 * parse.c (parse_tuple_element): Change interface to return
3547 reversed list, so don't call nreverse.
3548 * parse.c (parse_tuple): No longer nreverse element list here.
3549 * parse.c (parse_opt_element_list): Do nreverse here instead.
3550 * parse.c (parse_case_label_list): Call nreverse at end.
3552 Fri Jun 10 15:36:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
3554 * typeck.c (chill_similar): Remove bogus "else".
3556 Wed Jun 8 00:01:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
3558 * ch-tree.h (TYPE_ARRAY_MAX_SIZE): New macro (and comment)
3559 to make it clearer that we are using TYPE_MAX_VALUE in a special way.
3560 * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
3561 * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
3562 * convert.c (convert): When converting a fixed string/array
3563 to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
3564 of (the type of) the padding.
3565 * convert.c (convert): If the concatenation is non-constant, use
3566 the low-level 'build' to set the type of the result (which is usually
3567 a fixed-size array) rather than depend on build_chill_binary_op
3568 to figure it out (it's unable to simplify the size to a constant).
3570 Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
3572 * lang.c (lang_decode_option): Let -fspecial_UC imply
3573 -fno-ignore-case without requiring it explicitly.
3574 * lang.c (lang_decode_option): Support (experimentally)
3575 the -fpack and -fno-pack flags.
3577 Thu Jun 2 20:49:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3579 * configure: Add support for --program-prefix and --program-suffix.
3581 Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3583 * convert.c (digest_constructor): Check that initial value
3584 is compatible with element mode before calling convert.
3585 * typeck.c (chill_compatible): A string mode is not compatible
3586 with an untyped constructor.
3587 * decl.c (do_decl): Clean up error messages. Use error_with_decl.
3589 * ch-tree.h: Fix inconsistencies: bool_true_node ->
3590 boolean_true_node, and bool_false_node -> boolean_false_node.
3591 * typeck.c (valid_array_index_): Minor simplification.
3593 Tue May 31 04:33:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3595 * inout.c (build_chill_writetext): Add correct processing
3596 of POWERSET RANGE (setmode).
3598 * lex.l (same_file): Add searching for file(s) in
3601 Fri May 27 14:22:42 1994 Per Bothner (bothner@kalessin.cygnus.com)
3603 * Make-lang.c (CHILL.mostlyclean, CHILL.distdir): Don't list
3604 yacc/bison output files, since the grammer is no longer in yacc.
3605 * config-lang.in (diff_excludes): Likewise.
3607 Thu May 26 16:38:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3609 * gperf, hash.h, lex.l, parse.h: Rename PROCESS_TYPE token
3610 (in some files spelled PROCESS_TYPE_ to avoid clashes
3611 with the PROCESS_TYPE tree_code) to PROCESS_TYPE_TOKEN.
3613 Thu May 26 02:18:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3615 * timing.c (build_cycle_start): Change call to __define_timeout.
3616 * decl.c (init_decl_processing): Change definitions of
3617 __define_timeout and __wait_timeout.
3619 Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
3621 Replace yacc-based parser with a recursive-decent parser.
3622 (This may seem backwards, but Chill [like C++] is not a
3623 language that is remotely LALR(1). Using a R-D parser
3624 allows us to use look-ahead and to back-up to resolve the
3625 difficult ambiguities.)
3627 * parse.c, parse.h: New files, containing new r-d parser.
3628 * Makefile.in: Update accordingly.
3629 * actions.c (chill_convert_for_assignment): Don't return
3630 NULL_EXPR if ignore_exprs is true. It simplifies the parser
3631 if we consistently reserve NULL_EXPR for a missing expression.
3632 * expr.c (build_chill_function_call): Likewise.
3634 * lex.l: Tweaks for new parser.
3635 * lex.l (prepare_paren_colon, paren_paren_colon_level,
3636 paren_level): Ugly hack no longer needed.
3638 * expr.c (build_chill_function_call): Cleanup.
3639 Call chill_convert_for_assignment to convert IN/INOUT
3640 paramaters on both input and output. For LOC parameters,
3641 give error if actual is a non-referable location.
3642 * actions.c (convert_for_assignment): Add new parameter (a
3643 "place" string used in error messages).
3644 * actions.c (adjust_parm_or_field): Removed.
3645 * actions.c (chill_expand_assignment): Take just a single LHS,
3646 and move support for multiple assignments to ...
3647 (expand_assignment_action): ... here. Some cleaning up.
3648 * timing.c (build_cycle_start): Adjust accordingly.
3649 * actions.c (expand_assignment_to_varying_array): Likewise.
3650 * tasking.c (many places): Ditto.
3651 * ch-tree.h: Fix declarations appropriately.
3653 * parse.c (parse_defining_occurrence_list): Return a single
3654 IDENTIFIER_NODE (instead of a singleton list) in the common
3655 case. Minor complication to save a minor amount of space.
3656 * decl.c (do_based_decls): Move guts of code into ...
3657 (do_based_decl): ... this new function.
3658 * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
3659 * decl.c (push_syndecl): Replace by ...
3660 (push_syndecl): ... (which only supports a single name).
3661 (push_modedef): Only handle a single name.
3662 * tasking.c (build_process_header, build_signal_struct_type):
3665 * expr.c (build_generalized_call): Handle string repetition.
3666 * expr.c (build_chill_repetition_op): Change interface.
3667 * grant.c (decode_constant): Allow parameter list to be
3668 a non-TREE_LIST. (Used for string repetition.)
3670 Wed May 25 11:28:48 1994 Per Bothner (bothner@kalessin.cygnus.com)
3672 * lex.l (make_identifier): Replaced by ...
3673 (read_identifier, handle_name): ... new functions.
3674 * lex.l: Parse an identifiers using read_identifier using
3675 read_identifier and handle_name, rather than having [f]lex
3676 do it. (One reason is that lex uses a fixed-size buffer.)
3678 * lex.l (read_directive, skip_directive): New functions.
3679 Use them to parse compiler-directives, instead of rather
3680 ugly and useless use of lexer start conditions.
3682 Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3684 * decl.c (unnamed_module_number): Renamed to ...
3685 (module_number): .. and make non-static.
3686 (push_module): Always increment module_number.
3687 * lex.l (yywrap): Print warning if no modules seen.
3689 * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
3690 decl to current_seizefile_name (which is unreliable).
3691 * grant.c (chill_grant): Set it here instead.
3693 * expr.c (fold_set_expr): Use int_size_in_bytes instead of
3694 TYPE_PRECISION (which is not defined for a SET_TYPE).
3696 Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
3698 Cleanup to remove need for variables in common storage.
3699 * decl.c: Remove unused use of current_obstack.
3700 * actions.c (maybe_chill_check_decl): Remove unused function.
3701 * actions.h, lang.c: Remove uses of doing_chill_thang.
3702 * ch-tree.h (void_list_node): Make extern (rather than common).
3703 * decl.c (void_list_node): Add definition.
3705 Thu May 19 06:54:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
3707 * configure (build): Build canon_host and canon_target
3708 to pass it to all subsequently generated Makefiles (needed
3709 for testsuite/execute in case of cross build).
3711 Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
3713 * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
3714 the input type, which loses with the no-longer-new 2-pass
3715 implementation, since the input "type" could be an IDENTIFIER_NODE.
3716 * grant.c (raw_decode_mode): Rename to decode_mode.
3718 Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3720 * typeck.c (chill_location): Neither a STRING_CST nor a
3721 CONSTRUCTOR is a location.
3722 * typeck.c (chill_root_mode): Convert a function to a
3723 pointer-to-function.
3724 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3725 build_chill_arrow_expr): If ignore_exprs, return operand
3726 rather than NULL_EXPR. This makes it easier for the parser to
3727 distinguish missing expressions.
3728 * expr.c (build_max_min): Convert the lower bound of a
3729 set to a long before calling run-time routine.
3730 * expr.c (build_chill_pred_or_succ): Use discrete_type_p
3731 to check the argument type.
3732 * expr.c (build_chill_arrow_expr): If argument is not a location,
3733 do a predwarn if it is a STRING_CST or has function type.
3735 Tue May 17 06:05:13 1994 Wilfried Moser (moser@rtl.cygnus.com)
3737 * configure (build): Remove building of canon_host and canon_target.
3738 It doesn't work in any case.
3740 Mon May 16 02:10:35 1994 Wilfried Moser (moser@rtl.cygnus.com)
3742 * configure (build): Build canon_host and canon_target
3743 to pass it to all subsequently generated Makefiles (needed
3744 for testsuite/execute in case of cross build).
3745 * Make-lang.in (chill-runtime): Change chill to CHILL in the case
3746 statement to build chill-runtime automatically.
3748 Mon May 9 15:30:08 1994 Doug Evans (dje@canuck.cygnus.com)
3750 * Makefile.in (FLAGS_TO_PASS): Define.
3752 (../cc1chill): Depend on $(OBJDEPS) $(C_OBJS).
3753 * Make-lang.in (cc1chill): Delete dependency on $(OBJS) $(BC_OBJS).
3754 (CHILL.mostlyclean): Use `mostlyclean' as recursive target.
3756 Sun May 8 13:05:00 1994 Per Bothner (bothner@cygnus.com)
3758 * Make-lang.in (cc1chill): Should not depend on libgcc.a.
3760 Thu May 5 18:58:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
3762 * decl.c (copy_lang_decl): New (dummy) function.
3764 Mon May 2 14:33:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
3766 * parse.y (sendaction): Fix thinko (in sense of condition).
3767 * tasking.c (build_receive_case_label): Another thinko.
3769 * parse.y (optsigdest): Force ignore_exprs to 0 while parsing
3772 * decl.c (build_chill_function_type): Don't call layout_type
3773 (since that may prevent parameter or result types being
3774 properly satisfied).
3775 * satisfy.c (satisfy): Layout FUNCTION_TYPEs.
3776 * parse.y (procmode): Call build_chill_pointer_type, rather
3777 than build_pointer_type (which incorrectly sets TYPE_SIZE).
3779 * parse.y (get_type_of): Handle TYPE_DECL (again).
3780 * parse.y (optresultspec): Call build_chill_reference_type, rather
3781 than build_reference_type (which incorrectly sets TYPE_SIZE).
3782 * parse.y (range_or_mode): Rename to plain range, since it
3783 no longer matches modename.
3784 * actions.c (chill_handle_case_label_range): New function, with
3785 functionality moved out of chill_handle_case_label.
3786 * actions.c (chill_handle_case_label): Handle here the case that
3787 the label_value is a TYPE_DECL (modename). Also clean up some.
3788 * typeck.c (build_chill_slice_with_length): Convert max_index
3789 to the type of min_value. (Old code broke on varying strings.)
3791 Sun May 1 13:53:36 1994 Doug Evans (dje@canuck.cygnus.com)
3793 * Makefile.in (BC_OBJS): Delete all references
3794 (OBJS): Cat ../stamp-objlist to get language independent files.
3795 (../cc1chill): Delete dependency on $(OBJS).
3796 * Make-lang.in (cc1chill): Depend on stamp-objlist.
3798 Sat Apr 30 14:50:15 1994 Per Bothner (bothner@kalessin.cygnus.com)
3800 * lex.h, lex.c: Remove lastiddecl.
3801 * lex.l (name_type_signal): Simplify. We no longer check for
3802 TYPENAME or SIGNALNAME (which was unreliable with two passes).
3803 Also rename to make_identifier.
3804 * parse.y: Cleaned up grammar to not need SIGNALNAME or TYPENAME.
3805 * Makefile.in (stamp-parse); One conflict fewer!
3806 * parse.y (rccase_label_flag): Moved to tasking.c.
3807 * parse.y (rccase_label): Move most of the logic to
3808 build_receive_case_label in tasking.c.
3809 * parse.y (sendaction): Re-write to not depend on SIGNALNAME.
3811 * parse.y (name): Do name lookup here (and not in location).
3812 * parse.y: Replace most uses of NAME by higher-level non-terminals:
3813 simple_name_string, name_string, defining_occurrence, or name.
3815 * tasking.c (build_receive_signal_case_label,
3816 build_receive_buffer_case_label): New functions, split out from
3817 build_receive_case_label.
3818 * tasking.c (build_receive_case_label): Change parameters
3819 and return type. Moved stuff here (from the parser).
3820 * tasking.c (struct rc_state_type): Removed had_errors.
3821 Return error_mark_node instead.
3822 * tasking.c (build_rccase_set_error), ch-tree.h: Removed.
3824 * expr.c (build_generalized_call): If func is a signal type,
3825 call build_signal_descriptor.
3827 * parse.y (arrayindex): Renamed to index_mode, to match Z.200.
3828 * parse.y (ioindexmode): Removed; use index_mode instead.
3829 * expr.c (build_generalized_call): If args is a RANGE_EXPR,
3830 we have either a slice or a range mode, depending on func.
3831 * parse.y (index_mode): If we got an 'expr', only allow a name,
3833 * parse.y (call): A slice with both end points can be a range
3834 mode, so defer handling to build_generalized_call (or index_mode).
3836 * typeck.c (build_chill_slice_with_length): Fix type-checking.
3837 * typeck.c (chill_novelty): Undo (part of) change of April 28:
3838 The novelty of a range mode is the novlety of the parent.
3839 * typeck.c (chill_root_mode): Don't return integer_type_node
3840 if argument has non-nil novelty.
3842 * decl.c (global_bindings_p): Return -1 as true, for the sake
3843 of variable_size (in ../stor-layout.c).
3845 Fri Apr 29 13:42:43 1994 Per Bothner (bothner@kalessin.cygnus.com)
3847 * parse.y: Remove TYPENAME and modename. These are now plain
3848 NAMEs. Modify parsing actions appropriately.
3849 * expr.c (build_generalized_call): Handle the case that
3850 TREE_CODE (func) == TYPE_DECL (as in a cast).
3851 * lex.l (name_type_signal): Never return TYPENAME.
3852 * parse.y (get_type_of): If pass 1, just return the argument.
3854 * decl.c (do_decl): If an initializer has the wrong type,
3855 replace it by NULL_TREE, to avoid subsequent errors.
3857 Thu Apr 28 15:21:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
3859 * Makefile.in: Add new file timing.c to rules.
3860 * timing.c: New file. Implements the timing actions AT,
3862 * decl.c (init_decl_processing): Add new builtin function
3864 * expr.c (build_chill_indirect_ref): Change error message and
3865 add check agains an IDENTIFIER_NODE.
3866 * gperf, hash.h: Change EVENT_CODE, BUFFER_CODE to IGNORED_DIRECTIVE.
3867 They are no longer needed.
3868 * grant.c (print_integer_type): Add processing of builtin types
3870 * lex.l: Remove processing of directive EVENT_CODE & BUFFER_CODE.
3871 * parse.y (timingactions): split up to afteraction, ataction
3873 * parse.y (afteraction): New rule.
3874 * parse.y (ataction): New rule and put actions in.
3875 * parse.y (cycleaction): New rule and put actions in.
3876 * parse.y (sendaction): Add code for SEND buffer.
3877 * parse.y (rccase_label): Change error processing.
3878 * tasking.c (build_gen_inst): More checks.
3879 * tasking.c (build_gen_code): Add checking for argument is a

4338 * typeck.c (valid_array_index_p): Change interface to pass
4339 validity conditions back on caller's TREE_LIST. We
4340 cannot link the conditions to anything which a
4341 layout_type routine will expand, since that will occur
4342 before the exception handler is set up.
4343 Change calls to valid_array_index_p also.
4345 Fri Mar 18 14:40:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
4347 * actions.c, except.c, loop.c, tasking.c: Call
4348 build_chill_function_call instead of the C-specific
4349 build_function_call.
4350 * except.c (initialize_exceptions): Fix parmtype of __builtin_setjmp.
4351 * loop.c (top_loop_end_check): Coerce library function arg.
4352 * convert.c, expr.c: Re-write to avoid calls to C-specific
4353 function build_unary_op (e.g. by calling build1 directly).
4355 * typeck.c (chill_equivalent): Change to force failure
4356 for non-matching integral types (even if not ranges).
4358 * typeck.c, ch-tree.h (build_chill_slice): Make non-static.
4359 * expr.c (varying_to_slice): Call build_chill_slice (and not
4360 build_chill_slice_with_length, which does bunches of range
4361 checking and does not allow the length to be zero).
4362 * convert.c (convert): Fix off-by-one error.
4363 * actions.c (chill_expand_array_assignment): Minor cleaning up.
4365 Fri Mar 18 00:12:48 1994 Per Bothner (bothner@deneb.cygnus.com)
4367 * decl.c (init_decl_processing): __lepowerset and __ltpowerset
4368 take *two* pointer parameters, not one.
4369 * satisfy.c (satisfy): Only call the appropriate layout routine
4370 if TYPE_SIZE is 0 (i.e. type hasn't already been laid out).
4371 * typeck.c (build_chill_slice_with_length): Fix Bill's previous fix.
4373 Thu Mar 17 17:29:43 1994 Bill Cox (bill@rtl.cygnus.com)
4375 * expr.c (build_chill_function_call): Give function call the correct
4377 * typeck.c (build_chill_slice_with_length): Restore dynamic range
4378 checking, so it doesn't obscure the CONSTANTness of the length.
4380 Wed Mar 16 17:23:31 1994 Per Bothner (bothner@kalessin.cygnus.com)
4382 * typeck.c (build_chill_slice), expr.c (chill_expand_expr
4383 [case CONCAT_EXPR]): Remove kludge setting slice size upper bound
4384 in TYPE_LANG_SPECIFIC, and restore kludge setting it in MAX_VALUE.
4385 * typeck.c (build_chill_slice): Use TYPE_MAX_VALUE of
4386 array_type if needed for size upper bound of slice_type.
4387 * expr.c (build_concat_expr): Improve calculation of size upper bound.
4389 * typeck.c (valid_array_index_p): Check compatibility using
4391 * typeck.c (build_chill_slice_with_length); For now revert
4392 calling valid_array_index_p on length. (It makes it harder
4393 to realize when the slice is constant length.)
4394 * expr.c (build_chill_indirect_expr): Minor tweak. (This
4395 seems to work around a weird C compiler bug. ??)
4397 * expr.c (build_chill_function_call): Cleanup so it doesn't
4398 call build_function_call (in c-typeck.c).
4399 * typeck.c, expr.c: Use build_chill_function_call instead of
4400 build_function_call (in c-typeck.c).
4402 * parse.y (discrete_mode): Move some of the rules from
4403 non_array_mode into new non-terminal.
4404 (arrayindex): Use discrete_mode (with NAME and TYPENAME) to
4405 avoid some misparses.
4406 * ch-tree.h (SLICE_PTR, SLICE_LENGTH): Removed; unused.
4407 * convert.c (digest_structure_tuple): Add missing parameter.
4408 * decl.c (comptypes): Remove unused prototype.
4409 * decl.c (build_chill_function_type): Handle NULL return_type
4410 correctly (convert to void_type_node).
4411 * decl.c (init_decl_processing): layout boolean_type_node *after*
4412 we've set it's TYPE_MIN_VALUE and TYPE_MAX_VALUE.
4414 Wed Mar 16 16:08:22 1994 Bill Cox (bill@rtl.cygnus.com)

4417 * convert.c (convert): Correct calculation of padding length.
4418 * decl.c (grok_chill_fixedfields): Move ignore_exprs test to
4419 parse.y where it belongs. This permits the removal of a kludge
4420 in make_process_struct.
4421 * lex.l, parse.y: Call to_global_level for several errors. Add
4422 code to output error in only one pass.
4423 * tasking.c (make_process_struct): Delete kludge inserted on
4425 (build_receive_case_end): Add Wilfried's check for errors.

4429 * actions.c: Fix comment.
4430 (build_rts_call): Ifdef it out - never used.
4431 (expand_varying_length_assignment): call valid_array_index_p.
4432 rather than validate_varying_array_ref.
4433 * ch-tree.h: Fix prototype for valid_array_index_p.
4434 * expr.c (chill_expand_expr): Call build_chill_array_ref to get
4436 (build_hill_lower, build_chill_upper): Return value now inherits
4437 the novelty of the input parameter.
4438 (varying_to_slice): Use CH_NOVELTY macro rather than calling
4439 chill_novelty directly.
4440 * grant.c (newstring): Make len unsigned and cast xmalloc parameter
4442 (print_integer_type): Pass string value as APPEND's second parameter.
4443 (decode_decl): Pass a boolean expression as print_proc_tail's
4445 (chill_finish_module_code): Make xmalloc's parameter unsigned.
4446 * lex.l: Pass sizes to xmalloc as unsigned ints. Pass second
4447 parameter to in_word_set as unsigned.
4448 * loop.c (build_loop_start): Check top_loop_end_check return value.
4449 * parse.y: Add casts to int for third do_decls parameter, fifth
4450 build_loop_iterator parameter, etc.
4451 * tasking.c (build_receive_case_end): Chack cond_stack before popping.
4452 * typeck.c (validate_varying_array_ref, chill_max_vary_array_index,
4453 valid_array_index): Delete them. They're now unused.
4454 (valid_array_index_p): Add function, call it everywhere that an
4455 array index is checked.
4456 (build_chill_slice): Restore old functionality where varying_to_slice
4457 is called to handle slices of varying arrays, rather than handling
4459 (build_chill_slice_with_range, build_chill_slice_with_length):
4460 Check range limits for TREE_CONST before calling tree_int_cst_lt.
4461 Delete now-obsolete checks of constant indices.
4463 Mon Mar 14 17:26:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4465 * parse.y (modeless_expr): New rule to allow ([...]) and (if...)
4466 to count as untyped_exprs. (This is not really permitted by the
4467 Blue Book, but has been requested by customers.)
4469 Thu Mar 10 10:11:02 1994 Bill Cox (bill@rtl.cygnus.com)
4471 * chill.texi: Document new command-line options.
4472 * expr.c (build_chill_num): Set unsigned parameter for
4473 type_for_size call correctly (unsigned for enums).
4474 * lang.c (lang_decode_option): Add command-line options to
4475 enable/disable runtime range-checking.
4476 * lex.l: Eat more whitespace.
4478 Thu Mar 10 09:41:37 1994 Bill Cox (bill@rtl.cygnus.com)
4480 * Makefile.in: Have rules to make parse.h, y.tab.c and other
4481 derived files. This allows the gcc/configure list of CHILL
4482 files machinery to work.
4483 * ch-tree.h (permanent_allocation): Add a parameter flag.
4484 * decl.c (finish_chill_function, finish_decl): Provide the
4485 new permanent_allocation flag.
4486 (poplevel): Return early, avoid a seg fault.
4487 * lex.l (NORMAL): Replace this whole state with the predefined
4488 INITIAL state. Force compilation state to global level after
4489 compiler directive error - prevents endless loop on error.
4490 (handle_use_seizefile_directive): Rewrite for readability.
4491 (chill_same_grant_file): Reindent.
4492 Generally handle whitespace differently.
4493 * regression.prpt: Print ten PR numbers per line. The report's
4496 Wed Mar 9 09:58:51 1994 Bill Cox (bill@rtl.cygnus.com)
4498 * decl.c (do_decl): Suppress the string-assignment-condition
4499 error - it was too often seen.
4500 * expr.c (expand_chill_expr): In CONCAT_EXPR, when argument has a
4501 runtime-changing length (as in a slice), get the parent array's
4502 allocation size from its type tree.
4503 * typeck.c (build_chill_slice): Support VARYING arrays. Pass
4504 parent array's static allocation size along in the slice type.
4506 Wed Mar 9 08:54:24 1994 Bill Cox (bill@rtl.cygnus.com)
4508 * lex.l (name_type_signal): Avoid dereferencing a NULL TRE_TYPE.
4510 Tue Mar 8 11:51:10 1994 Bill Cox (bill@rtl.cygnus.com)
4512 * expr.c (build_chill_sizeof): Fix typo in error msg, add
4514 * lex.l (name_type_signal): Add debug output.
4515 * parse.y (call): Allow EVENTNAME and BUFFERNAME parameters
4516 to a call, so that SIZE () works on them.
4517 * tasking.c (make_process_struct): Force ignore_exprs non-zero
4518 when processing a SEIZEd PROCESS declaration. This prevents
4519 grox-fixed_fields from returning a NULL, and indirectly protects
4520 the chill_integer_type_node tree from corruption.
4522 Mon Mar 7 19:14:05 1994 Bill Cox (bill@rtl.cygnus.com)
4524 * Makefile.in: Use the 'all' target to build the runtime
4525 library and chillrt0.o.

4528 chill.regress.cron: Move to utils subdirectory.
4529 * expr.c (build_chill_function_call): Mark the INOUT
4530 temporary so it doesn't get optimized into a
4531 register. Fixes the execute/inout.ch bug.
4532 * typeck.c (layout_chill_range_type): Restrict it
4533 from complaining about an empty string type's
4536 Mon Mar 7 09:06:39 1994 Bill Cox (bill@rtl.cygnus.com)

4569 * lex.l (INITIAL): Remove all code to discard 'header lines'.
4571 * parse.y (optheader): Remove - it's obsolete, as is the
4572 HEADEREL token definition.
4574 Fri Mar 4 09:41:18 1994 Bill Cox (bill@rtl.cygnus.com)
4576 * addtest: Fix suffix removal when suffix is .c186.
4577 * regression.sh: Allow for underscores on PR filenames.
4578 * typeck.c: Check in the rewrite mentioned earlier.

4596 range-checking code. Handle reference_type in convert call.
4597 (chill_expand_assignment): Produce an INDIRECT_REF for a

4671 name for correctness.
4673 Wed Feb 23 15:07:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4675 New cleaner solution to the following problem:
4676 Chill allows an action to be followed by an ON-handler.
4677 But we don't know if an action has a handler until we've parsed
4678 its end, yet we want to generate extra code to set up an
4679 exception handling contour only if needed. The old solution
4680 would generate code for the action into an rtl sequence, and then
4681 splice in the exception-setup code if we later found we needed it.
4682 This has a few problems (for example it confuses the management
4683 of stack temporaries), and is ugly. Now that the compiler is 2-pass
4684 we have a cleaner solution: In pass 1, we remember which actions
4685 were followed by ON-handlers. In pass 2, we use this information
4686 to generate appropriate code before an action.
4687 * except.c (push_handler, pop_handler): In pass 1, set up data
4688 structures (global_handler_list) to remember if an action has an
4689 ON-handler. In pass 2, digest this information, and setup
4691 * except.c, actions.h (pop_handler): Take an extra int arg.
4692 * except.c (emit_setup_handler): New function, with code (moved
4693 from chill_start_on) to emit code before an action that has a handler.
4694 * except.c (except_init_pass_2): New function.
4695 * parse.y (pass1_2): Call except_init_pass_2 before pass 2.
4696 * parse.y (POP_UNUSED_ON_CONTEXT): Don't call pop_sequence.
4697 * parse.y: Invoke POP_UNUSED_ON_CONTEXT and POP_USED_ON_CONTEXT
4698 in pass 1 as well as pass 2.
4699 * parse.y (BEGIN ... END): Re-arrange logic to avoid block_stack
4700 (local to ../stmt.c) getting out of sync.
4701 * actions.c (push_action): Don't need to emit a NOP,
4702 now that we're no longer moving sequences around.
4703 * actions.c (push_action): Call push_handler even in pass one.
4705 Wed Feb 23 11:06:14 1994 Bill Cox (bill@rtl.cygnus.com)

4768 mis-match if the LHS is varying.
4770 Fri Feb 18 18:10:04 1994 Bill Cox (bill@rtl.cygnus.com)

5304 * chill.regress.cron: Add crontab file for regression tests.
5305 * regression.sh: Add regression test control script.

5310 Sat Jan 15 14:54:07 1994 Bill Cox (bill@rtl.cygnus.com)
5312 * ch-*.*: All of these files are now moved to the ch subdirectory.
5313 Further update changes should be recorded in the ch/ChangeLog file.

5318 ch-satisfy.c, ch-typeck.c: Undo all of initializer-related changes
5319 that Tiemann did earlier this month.
5320 * c-typeck.c (really_start_incremental_init): Save
5321 constructor_elements and (old value of) constructor_stack
5322 on constructor_stack, to allow for nested initializers.
5323 * ch-convert.c (digest_constructor): If we need a varying
5324 array, and have a constructor (for the array elements),
5325 make sure to use convert so that the constructor gets
5326 wrapped in an implicit record constructor.
5327 * ch-decl.c (do_decl): If there is no initializer for a
5328 varying array (or bitstring), create default constructor.
5330 * ch-expr.c (build_chill_lower): Fix thinko for ARRAY_TYPE.
5331 * ch-satisfy.c (safe_satisfy_decl): Make sure that we make
5332 original decl to check if we need to make an rtl.
5334 * ch-typeck.c (build_chill_array_ref_1), ch-tree.h: New function
5335 which does the actual work for build_chill_array_ref (which
5336 now just loops over an argument list).
5337 * ch-actions.c, ch-expr.c, ch-inout.c: Use build_chill_array_ref_1
5338 instead of build_chill_array_ref where appropriate.
5339 * ch-actions.c, ch-expr.c, ch-typeck.c: Make operand 1 of a
5340 VARY_ARRAY_REF is a single index, not an index list.
5342 * ch-grant.c (__init_list): Renamed to _ch_init_list, to
5343 avoid a conflict on the Alpha.
5345 Wed Jan 12 10:19:35 1994 Bill Cox (bill@rtl.cygnus.com)
5347 * ch-lex.l (WS): Add BS, VT and CR to definition of

5354 conditional so error messages are output.
5355 * ch-expr.c (build_chill_addr_expr): Add error message.
5356 * ch-grant.c (chill_finish_module_code): Avoid abort by
5357 giving the init_list constructor a type.
5358 (chill_finish_compile): Delete unused code.
5359 * ch-lex.l: Make most build_init_2 calls from the
5360 permanent obstack, so that enumeration values endure.
5361 * ch-loop.c (build_chill_iterator): Add several error
5364 Tue Jan 11 12:31:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
5366 * ch-expr.c, ch-typeck.c: Rewrite some instances of
5367 'struct ch_class class = chill_expr_class (expr);' to
5368 'struct ch_class class; class = chill_expr_class (expr);'
5369 to work around a bug in /usr/ucb/cc on SunOS4.
5371 Mon Jan 10 18:29:36 1994 Bill Cox (bill@rtl.cygnus.com)
5373 * ch-actions.c (chill_convert_for_assignment): Avoid seg fault.
5374 * ch-expr.c (expand_packed_set): Add new parameter to pass
5375 set's minimum ordinal value. Fix loop invariant problem.
5376 (fold_set_expr): Change to add new parameter to
5377 expand_packed_set call.
5378 * ch-grant.c: Move extern declaration to ch-tree.h.

5392 Convert result to correct class.
5393 * ch-expr.c (build_chill_repetition_op): Preserve CH_DERIVED_FLAG.
5394 Also, fix some bugs for bitstrings (with ranges).
5396 (Patches from Tiemann.)
5397 * ch-convert.c (convert1): New function to force TREE_TYPE.
5398 (convert): Use convert1 where appropriate.
5399 * ch-typeck.c: Formatting change.
5400 * ch-parse.y (build_chill_constructor): Fix thinko.
5402 * ch-expr.c (varying_to_slice): If array is not referable,
5403 call save_expr on it, rather than stabilize_reference.
5404 * ch-satisfy.c (safe_satify_decl, for CONST_DECL):
5405 Don't force value to value class if mode is not explicitly
5406 specified. Also, make sure convert etc is only done once.
5408 Sat Jan 8 16:37:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
5410 * ch-decl.c (build_chill_function_type): Don't call
5411 build_function_type, because it does hash canonicalization,
5412 which once in a while looses badly.
5413 * tree.c (build_function_type): Remove no-longer-needed test
5414 for doing_chill_thang.
5416 * ch-tree.h (CH_DERIVED_FLAG): New flag.

5430 convert_float, convert_number): Set CH_DERIVED_FLAG for literals.
5431 * ch-expr.c (finish_chill_binary_op): Use convert_to_class.
5432 * ch-satisfy.c (safe_satisfy_decl): For CONST_DECL, make sure
5433 DECL_INITIAL gets set to result of convert.
5434 Also, clear CH_DERIVED_FLAG for SYN value.
5435 * expr.c (store_constructor): If a [power]set is exactly one
5436 word long, use single-word move.
5438 Sat Jan 8 08:38:29 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5440 * c-typeck.c (chill_initializer_constant_valid_p): Fix typo.
5442 Wed Jan 5 05:18:46 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5444 * ch-typeck.c (build_chill_slice_with_length): Test that ARRAY is of
5445 ARRAY_TYPE before assuming so. Also, subtract 1 from LENGTH in
5446 computation of SLICE_END.
5448 * ch-typeck.c (chill_location): Treat CONSTRUCTORs like STRING_CSTs.
5450 * ch-expr.c (build_chill_indirect_ref): Handle MODE == NULL_TREE.
5452 * ch-expr.c (fold_set_expr): Handle OP1 == NULL_TREE (which happens
5453 for unary set operations).
5455 * ch-expr.c (build_chill_array_expr): Take new argument FORCE. All
5456 callers changed. All callers changed.
5458 * ch-convert.c (digest_structure_tuple): Handle SELECTED_VARIANT
5459 being NULL_TREE until we've started walking the list of values via
5460 the loop over VARIANTs.
5462 * ch-parse.y (build_chill_constructor): If we see an IDENTIFIER_NODE,
5463 treat it as an enum value (and hence constant). Also, only set
5464 TREE_STATIC if the constructor is indeed constant.
5465 * c-typeck.c (chill_initializer_constant_valid_p): If we see a
5466 VAR_DECL, test the TREE_CONSTANT field of the DECL_INITIAL, don't
5467 recurse on the DECL_INITIAL.
5469 Wed Jan 5 01:24:50 1994 Bill Cox (bill@cygnus.com)
5471 * Makefile.in: Add CHILL to LANGUAGES variable.
5472 * ch-actions.c (check_range): Call build_binary_op instead of
5473 fold, build to get the common types chosen.
5474 (cond_range_exception, cond_overflow_exception,
5475 cond_type_range_exception): Delete, obsolete.
5476 (chill_convert_for_assignment): Enable this, get particular
5477 about when to generate rangecheck code.
5478 * ch-expr.c (build_chill_function_call): Sketch in where to
5479 perform chill_convert_for_assignment on actual parameters.
5480 (build_chill_addr_expr): Correct compiler warning.
5481 * ch-loop.c (build_chill_iterator): Add runtime check for
5482 negative loop step expression.
5483 * ch-tree.h: Add prototype.
5484 * ch-typeck.c (chill_max_vary_array_ref): Correct misunderstanding.
5485 A varying array's length field counts the NUMBER of active array
5486 array entries, not the byte-length of them.
5488 Tue Jan 4 17:57:39 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5490 * ch-decl.c (do_decl): Call `suspend_momenary' if the
5491 converted constructor must live on the permanent_obstack.
5492 * ch-convert.c (convert): When building a new SET_TYPE
5493 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5494 * c-typeck.c (chill_initializer_constant_valid_p): Handle VAR_DECLs.
5496 * ch-typeck.c (chill_location): CONSTRUCTORS that are static
5498 * ch-satisfy.c (safe_satisfy_decl): Convert DECL_INITIAL of CONST_DECL
5499 on permanent_obstack if necessary.
5501 * ch-convert.c (digest_structure_tuple): When building a new SET_TYPE
5502 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5504 * ch-decl.c (do_decl): Fix handling of REFERENCE_TYPEs which
5505 the patch below helped to mess up.
5507 * ch-expr.c (build_chill_arrow_expr): Call `mark_addressable'.
5508 (build_chill_addr_expr): Take new argument ERRORMSG.
5509 All callers changed. Also, call `build_chill_addr_expr' where
5510 we used to call `build1 (ADDR_EXPR, ptr_type_node, ...)' since
5511 that now calls `mark_addressable' automagically.
5513 * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.
5514 This is needed because variables may appear in initialization
5515 statements, and their DECL_INITIALs are their values at
5516 initialization time.
5517 * ch-convert.c (digest_structure_tuple,digest_constructor): Changed
5518 to handle VAR_DECLs as initializers.
5520 * ch-convert.c (digest_structure_tuple): Copy elements of INITS so
5521 they aren't destroyed for later use.
5523 Tue Jan 4 15:25:30 1994 Bill Cox (bill@cygnus.com)
5525 * ch-expr.c (chill_expand_expr): Correct check-range lo_limit
5526 parameter for varying_array_ref calculations.
5527 (build_chill_indirect_ref): Prevent seg fault due to syntax error.
5528 * ch-typeck.c (build_chill_slice_with_range): Correct issuance
5529 of bogus error in votrics.
5530 (build_chill_slice_with_length): Change for debug tracability.
5532 Tue Jan 4 02:43:37 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5534 * ch-convert.c (digest_structure_tuple): Fix phasing problem in
5535 handling variant record initializers.
5536 (various places): Change `pop_init_level' calls to match
5537 `push_init_level' wrt implicit variable.
5539 * ch-typeck.c (build_chill_slice): Convert the dynamic max index to
5540 `integer_type_node' before using it in comparisons. FIXME: should
5541 this be done in `chill_max_vary_array_index' by default?
5543 Tue Jan 4 00:24:14 1994 Bill Cox (bill@cygnus.com)
5545 * ch-actions.c: Fix comments.
5546 * ch-parse.y: Define caseaction_flag.
5547 (caseaction): Create new caseaction_flag node at the start,
5548 then free it at the end. Check it before the ELSE code.
5549 (expanded_case_label): Check the flag here. If set in either
5550 place, generate a jump to the end of the case.
5551 * ch-typeck.c (build_chill_slice_with_length,
5552 build_chill_slice_with_range): Add lots of compile-time
5553 parameter range checking.
5555 Mon Jan 3 21:49:04 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5557 * ch-convert.c (digest_structure_tuple): Call `push_init_level' with
5558 implicit==0 everywhere, not 1.
5559 (digest_constructor): Ditto.
5561 * ch-actions.c (check_range): Permit limits to be NULL_TREE.
5562 Also, hack out some dead code.
5563 * ch-typeck.c (build_chill_slice): Check varying and non-varying
5564 slice constructs for range failures.
5565 (build_chill_slice_with_range): Reindented, but not changed.
5567 * ch-typeck.c (chill_max_vary_array_index): New function.
5568 * ch-expr.c (chill_expand_expr): Call it.
5570 * ch-decl.c (var_data_id, var_length_id): New variables.
5571 (init_decl_processing): Initialize them. All calls to
5572 get_identifier (VAR_LENGTH or VAR_DATA) are now replaced
5573 by references to these variables. This simplifies the code
5574 w/o obscuring anything.
5576 Mon Jan 3 21:24:44 1994 Bill Cox (bill@cygnus.com)
5578 * c-typeck.c: Fix comment.
5579 * ch-actions.c (chill_expand_assignment): Error assigning to
5580 READONLY location. (PR_3903) Pass filename, linenumber
5581 to setbitpowerset runtime routine.
5582 * ch-decl.c (init_decl_processing): Add filename, linenumber
5583 parameters to setbitpowerset prototype.
5584 * ch-expr.c (build_chill_function_call): Error when passing a
5585 READonly location as a LOC or INOUT parameter.
5586 * ch-parse.y (mode): Correct code marking type as readonly.
5588 Mon Jan 3 19:03:55 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5590 * ch-actions.c (chill_expand_assignment): Disable code that defeats
5591 building varying array references.
5592 * ch-expr.c (chill_expand_expr): Add rangecheck code to
5593 VARY_ARRAY_REF case.
5594 * ch-typeck.c (build_chill_array_ref): Don't call an `expand_'
5595 function (in this case, `validate_varying_array_ref') when we're
5596 doing a `build_' operation.
5598 * ch-typeck.c (validate_varying_array_ref): Simplify interface
5599 since INDEX parameter can never meaningfully be an INDEXLIST.
5600 * ch-actions.c (expand_varying_length_assignment): Caller changed.
5602 Mon Jan 3 07:29:45 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5604 * ch-typeck.c (build_chill_cast): Set TREE_CONSTANT on NOP_EXPRs.
5605 * ch-convert.c (digest_structure_tuple): Switch to permanent_obstack
5606 if we need to build a CONSTRUCTOR for a SET_TYPE initializer.
5607 (digest_structure_tuple): If TREE_VALUE (VALUE) == NULL_TREE, don't
5608 call CH_COMPATIBLE or try to convert it to TREE_TYPE (FIELD). This
5609 can happen when constructors are output incrementally.
5610 * c-typeck.c (initializer_constant_valid_p): Handle SET_TYPEs.
5611 * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
5614 Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5616 * ch-convert (digest_structure_tuple): Handle SET_TYPEs. Also, call
5617 `convert' so we can handle INSTANCE types (and other anomolies)
5620 * ch-convert.c (digest_structure_tuple): Fixed variant
5621 structure initialization. Also fixed a typo (TYPE_NAME
5622 was being used on a FIELD_DECL instead of DECL_NAME).
5623 * c-typeck.c (initializer_constant_valid_p): Pass missing
5624 ENDTYPE argument on recursive call.
5625 (set_init_field): New function, needed by ch-convert.c change above.
5627 * ch-decl.c (layout_chill_variants): Added a FIXME next to an
5628 almost certain typo.
5630 * ch-expr.c (build_chill_arrow_expr): Call `build1' and set
5631 TREE_CONSTANT for static references.
5632 * ch-except.c (chill_start_on): Change calls to
5633 `build_unary_op' (which is C-specific) to `build_chill_arrow_expr'
5634 which has CHILL semantics.
5635 * ch-convert.c (convert): Ditto (albeit in some disabled code).
5637 Sat Jan 1 21:26:43 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5639 * ch-satisfy.c (safe_satisfy_decl): Reorder conditional test of
5640 TREE_CODE of DECL in case it's altered by actions in the switch.
5642 * ch-satisfy.c (satisfy): Undo abort added earlier on 1 Jan. CVS log
5643 mentions where to find code that triggers this case.
5645 * ch-actions.c (adjust_parm_or_field): Handle CONSTRUCTORS here as
5648 * ch-convert.c (digest_structure_tuple): Push to permanent_obstack if
5649 we're dealing with a CONSTRUCTOR that is TREE_PERMANENT.
5650 (digest_constructor): Ditto.
5652 Sat Jan 1 10:29:19 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5654 * ch-parse.y (handleraction,resultaction,assignaction,call): Modified
5655 so that CONSTRUCTORS are properly handled before being used.
5657 * ch-convert.c (chill_start_init): New function. All callers to
5658 `start_init' changed to call this function instead.
5659 (digest_struct_tuple): Defend against initialization machinery
5660 mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
5661 IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
5662 needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
5663 can be refered to throughout the compilation unit. Also remove an
5664 extraneous call to `process_init_element' erroneously added to the
5665 variant record sub-loop.
5666 (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
5667 CONSTRUCTORS of SET_TYPE.
5668 * ch-parse.y (build_chill_constructor): Refix typo. Also set
5669 TREE_STATIC if at top level.
5671 * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
5672 TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
5673 should have been called.
5675 * ch-convert.c (digest_struct_tuple): Restore code which tracks
5676 field initializations so that the compiler can deduce what variant
5677 initializations to assume.
5679 * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
5680 when we push into a scope that has a DECL with a CONSTRUCTOR as its
5683 * ch-parse.y (build_chill_constructor): Change the name of the
5684 parameter to something more meaningful. Fix typo. Also, handle case
5685 where element is an untyped CONSTRUCTOR.
5687 * ch-except.c (finish_handler_array): Set TREE_CONSTANT on
5688 constant ADDR_EXPRs.
5689 (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT
5690 on JBUF_REF (instead of calling `build1' which does not).
5692 * ch-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
5694 * ch-typeck.c (chill_expand_tuple): Deleted.
5695 * ch-parse.y (primval rule): Don't call `chill_expand_tuple';
5696 instead, use initialization machinery for CONSTRUCTORS that
5698 * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
5699 that are created here.
5700 * ch-satisfy (satisfy): Abort in case we would have called
5701 chill_expand_tuple. FIXME: some other code is needed here,
5702 but I don't know what yet.
5704 * ch-parse.y (build_chill_constructor): New function to
5705 propagate TREE_CONSTANT bits to CONSTRUCTORS.
5706 (untyped_expr rule): Use it.
5707 (primval rule): Use it.
5709 * ch-decl.c (do_decl): Call `finish_init'.
5710 * ch-convert.c (convert): If we spontaneously create a CONSTRUCTOR in
5711 this function, make sure the initialization machinery is set up.
5713 * ch-convert.c (digest_structure_tuple, digest_constructor): Add
5716 Fri Dec 31 11:31:01 1993 Michael Tiemann (tiemann@blues.cygnus.com)
5718 * ch-grant.c (chill_finish_module_code): Mark ADDR_EXPR built by hand
5719 as being TREE_CONSTANT. Otherwise it gets bounded by the initializer
5722 * ch-decl.c (do_decl): Change in CONSTRUCTOR handling due to...
5723 * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
5724 rewritten to work with GCC's initialization code. The basic change
5725 was to keep the initializers in sync with the initialization
5726 machinery that `process_init_element' imposes. Both of these
5727 functions now return `void'.
5728 * ch-convert.c (convert): Changed calls to `digest_...' functions.
5730 FIXME: the code handling UNION_TYPE (and variant records) has not
5733 Fri Dec 31 15:32:56 1993 Bill Cox (bill@rtl.cygnus.com)
5735 * ch-lex.l (convert_number): Output the converted number if
5737 * ch-parse.y (signaldef): Set ignore_exprs correctly for a
5740 Fri Dec 31 13:17:48 1993 Bill Cox (bill@cygnus.com)
5742 * ch-parse.y: Cleanup handling of RETURN actions, to distinguish
5743 a RETURN without a value (which cannot have an exception
5744 handler) from a RETURN with a value (which can). Eliminate
5745 some shift/reduce and reduce/reduce conflicts.
5747 Thu Dec 30 17:42:32 1993 Michael Tiemann (tiemann@blues.cygnus.com)
5749 * ch-inout.c (build_chill_writetext): Deal with 2 cases where
5750 types returned from `type_for_size' are not expected. FIXME.
5751 * ch-decl.c (init_decl_processing): Mark `char_type_node' unsigned.
5752 This is required when range checking is enabled.
5754 Thu Dec 30 14:28:25 1993 Bill Cox (bill@rtl.cygnus.com)
5756 DELAY CASE works now.
5757 * ch-decl.c (init_decl_processing): Move rest of tasking-related
5758 initialization into tasking_init().
5759 * ch-parse.y (delaycaseaction): Pervasive additions/corrections.
5760 (optsetprio): New non-terminal.
5761 * ch-tasking.c (get_task_name): Delete, obsolete.
5762 (build_instance_type): build pointer to instance type also.
5763 (build_receive_case_start): Cleanup per -Wall messages.
5764 (build_receive_case_label): Move between start and end functions.
5765 (build_delay_case_start): Pass SET name and priority also.
5766 Generally update to correct functioning.
5767 (build_delay_case_label): Move between start and end fucntions,

5786 Tue Dec 28 18:20:14 1993 Bill Cox (bill@rtl.cygnus.com)
5788 DELAY actions work now.
5789 * ch-decl.c: Correct spelling in comments.

5793 * ch-expr.c (build_chill_indirect_ref): Prevent a syntax error from
5794 becoming a seg fault.
5795 * ch-grant.c: Correct a comment.
5796 * ch-loop.c: Delete/correct comments.
5797 * ch-parse.y (delaycaseaction): Add push/poplevel calls. Turn 'sorry'
5798 into rough draft of actual code.
5799 (delayaction): Don't make a new scope here, use get_unique_identifier
5801 (locdec): process event decls here, too.
5802 (mode): Add code to forbid READonly EVENT and BUFFER decls. Delete
5803 code which required EVENTs and BUFFERs to be declared at global scope.
5804 (simple_name_string): Add an EVENTNAME.
5805 * ch-satisfy.c (safe_satisfy_decl): Prevent a syntax error from
5806 becoming a seg fault.
5807 * ch-tasking.c (tasking_setup): Add the event queue's max. length

5820 * gcc.c (CHILL SPECS): Delete references to -M -MM -MD -MMD
5821 options. Delete C-specific defines. Disable piping from
5822 pre-processor to cc1chill (even if -pipe is specified), since cc1chill
5823 rewinds its input for its second pass. Piping still works
5824 from cc1chill to as.
5826 Thu Dec 23 12:31:55 1993 Bill Cox (bill@rtl.cygnus.com)
5828 * ch-tasking.c (decl_tasking_code_variable): Assure that the

5835 Wed Dec 22 10:46:31 1993 Bill Cox (bill@rtl.cygnus.com)
5837 * ch-decl.c (do_seize): Delete - it's unused. Fix comments.
5838 * ch-loop.c (build_chill_iterator): Convert BY expression

5864 distinguish a string from a char array, and to distinguish a
5865 bitstring from regulat (power)set. (Needed for Chill.)
5866 * dbxout.c (dbxout_type): Only check for baseclasses in
5867 type.binfo is a vector. (It is used in Chill for tagged unions.)
5869 Fri Dec 17 09:56:07 1993 Bill Cox (bill@rtl.cygnus.com)

5889 * ch-tree.h: Fix prototypes.
5890 * ch-typeck.c (smash_dummy_type): Handle all four kinds of LANG_TYPE

5907 * ch-decl.c (push_scope_decls): Re-arrange so that normal
5908 (non-seize) declarations are proclaim_decl'd *before* we
5909 handle the ALIAS_DECLs for seizes. The advantage is
5910 that we can now test for (an approximation) to the
5911 'seizeable' concept, thus avoiding duplicate definitions
5912 when a module has both GRANTs and SEIZE ALL.
5914 * ch-expr.c (build_chill_arrow_expr): No longer re-write
5915 addr-of-conversion to pointer-conversion-of-addr.
5916 * ch-expr.c (build_chill_addr_expr): Re-write to just use

5925 * ch-expr.c (finish_chill_binary_op): Use CH_ROOT_RESULTING_MODE
5926 macro (which works on expressions), rather than CH_RESULTING_MODE
5927 (which works on modes, and isn't quite correct).
5928 * ch-tree.h (CH_IS_BOUND_REFERENCE_MODE): New macro.
5929 * ch-typeck.c (chill_read_compatible, chill_compatible):
5930 Use the new macro, which handles NEWMODEs of PTR correctly.

5932 dynamic-length array (and string) types (e.g. slices).
5933 * ch-typeck.c (chill_root_mode): If the mode has a Novelty,
5934 just return it as is. (This is still not 100% correct for
5935 NEWMODE of RANGEs, but is close enough.)

6054 of set elements of similar set modes.
6056 * ch-parse.y (caseaction): Call language-independent
6057 expand_start_case rather than c_expand_start_case (which

6668 (sigdef): Comment out special handling for external signals.
6669 Chain tasking_variable_decl onto signal structure decl, for
6670 easier non-symbol-table access later.
6671 * ch-tasking.c (generate_tasking_code_variable): Do work in both
6672 passes, using do_decl so we can pass the pass 2 value of the
6673 process_type or signal_code to it. Only update the process_type
6674 if the incoming pointer isn't null and pass == 2. Use a new
6675 parameter to know whether to include an init expression.
6676 (build_process_header): Attach tasking-code_variable to process
6677 function_decl for easy access later, not through the hash table.

6692 generation for decls to not use DECL_ASSEMBLER_NAME.
6693 * ch-decl.c: Set DECL_ASSEMBLER_NAME to DECL_NAME.
6694 This matches C, and allows dbxout to emit proper user-level names.
6695 (It would be cleaner to fix dbxout to use DECL_NAME ...)
6696 * ch-decl.c (outer_decls): New global list of the decls granted
6697 into the outer scope.

6719 not error_mark_node.
6720 * ch-actions.c (chill_expand_assignment): Allow such borderline
6721 constructs as: LHS OR:= [X].

6724 * ch-decl.c (do_decl): Remove CONSTRUCTOR kludge.
6725 * ch-typeck.c (chill_compatible): Allow expr to have NULL mode
6726 if it's a CASE_EXPR or COND_EXPR (and not just CONSTRUCTOR).

6740 commented-out code as example for assignment of module address to its
6743 Sun Oct 17 15:16:54 1993 Bill Cox (bill@cygnus.com)
6745 * ch-convert.c: Move semicolon to separate line - easier to see.
6746 * ch-decl.c (do_decl): Handle untyped_expr initializers by
6747 simply using the variable's declared type - no compatibility
6748 check can be made if the expression has no type.

6751 (fold_set_expr): Fix two other endless loops by passing
6752 correct parameters to unpack_set_constructor.

6986 stabilize_reference on RHS.
6987 * ch-typeck.c (build_chill_modify_expr), ch-tree.h: Remove

7011 push_extern_process and push_extern_signal.
7012 * ch-parse.y (end_function): Delete parameter. Check current_function_decl
7013 whether it's actually a process, and whether it has parameters.
7014 Make Michael's change simplifying the pass 2 test, preventing a seg

7017 code saving value from build_process_header. Delete redundant chill_
7018 phrases from some function calls.
7019 * ch-tasking.c: Remove some redundant _chill phrases from function
7021 * ch-tree.h: Remove some redundant _chill phrases from function
7022 names. Add the CH_VARYING_ARRAY_TYPE macro, call it from

7102 * ch-decl.c (find_implied_types): New interface. Now pre-pend
7103 new enum types to a given input list. This makes it easier to

7107 functionality over new functions (push_scope_decls, pop_scope_decls,
7108 build_implied_names, bind_sub_modules). The goal (which seems to
7109 have been more-or-less attained) was to fix weak name handling.
7110 * ch-decl.c (poplevel): Use new function pop_scope_decls.
7112 * ch-tasking.c (build_signal_struct, build_tasking_message_type):
7113 Use build_decl directly, rather than grok_chill_fixedfields
7114 (which depends on ignore_exprs and has more overhead).
7115 * ch-tasking.c (build_signal_struct): Construct the type
7117 * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
7118 than build_array_ref (which does C-specific "optimizations").
7119 (Hence move my_build_array_ref up earlier in the file.)
7121 Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7123 * ch-tasking.c: Declare static variable `void_ftype_void'.
7124 (chill_tasking_init): Initialize `void_ftype_void' here.
7125 (build_tasking_struct): Use, don't declare `void_ftype_void'.
7126 (generate_tasking_code_variable): Call `do_decl', not
7127 `decl_temp1' to declare TASKING_CODE_NAME.
7128 (tasking_setup): Drop into 1-pass mode so that all
7129 tasking-related declarations are installed in the global
7130 scope. Use correct CHILL types for initializers (since
7131 ptr_type_node doesn't have the right meaning for CHILL).
7132 Also, call `do_decl' instead of `decl_temp1' for
7134 (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
7135 `chill_finish_compile' in sync between passes.
7137 * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
7138 declarations on pass zero. Keep obstacks in sync, and always
7139 call `finish_decl' for pass zero declarations.
7140 (push_chill_extern_function): Keep obstacks in sync, and always
7141 call `finish_decl' for pass zero declarations.
7142 (build_enumerator): Ditto.
7143 (grok_chill_variantdefs): Change PASS test to exclude only
7145 (finish_struct): Ditto.

7153 * ch-decl.c (build_chill_exception_decl): Clarify reasons for
7154 extra pushing and popping of obstacks.
7156 * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
7157 on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
7159 * ch-grant.c (chill_finish_compile): Clear out both
7160 MODULE_INIT_LIST and TASKING_LIST if either contains stuff
7163 * ch-parse.y (rccase_label): Add NAME rules so that pass one
7164 works w/o knowing we're parsing a signal. Simplify SIGNALNAME
7165 rules since we only get SIGNALNAME tokens in pass two.
7166 (sendaction): Ditto.
7167 * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
7168 BUFFERNAME on pass two. The grammar now handles this.
7169 * ch-decl.c (lookup_remembered_decl): Deleted.
7171 Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
7173 * ch-decl.c (lookup_remembered_names): Removed. It was being
7174 misused in ch-lex.l.
7175 * ch-lex.l (name_type_signal): Revert last change. Basically,
7176 we cannot use the C typedef/variable name trick in CHILL, due
7177 due to the language's 2-pass nature.
7178 * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
7180 * ch-tree.h (lookup_remembered_name): Comment out the prototype.
7182 Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7184 * ch-decl.c (do_decl, push_chill_extern_function): Change pass
7185 checks so the pass == 0 case is handled for built-in types.
7186 (push_modedef): Add check for error_mark_node.
7187 (lookup_remembered_decl): New function.
7188 (pushlevel, poplevel) Change pass checks.
7189 (pushdecl): Check type as well for NULL.
7190 (build_enumerator): Handle pass == 0 case.
7191 * ch-lex.l: Use lookup_remembered_decl to get lastiddecl
7193 * ch-parse.y: Set pass to zero to indicate initial decl processing.
7194 Replace NAME references with SIGNALNAME references.
7195 (startaction): Only check copy number if not ignoring actions.
7196 Always call build_chill_start_process.
7197 (optstartset): Don't lookup the instance name.
7198 * ch-tasking.c (generate_tasking_code_variable): Replace
7199 do_decl call with decl_temp1 call.
7200 (build_chill_start_action): Check for ignore_actions here.
7201 (build_tasking_message_type): Layout the type.
7202 (rc_state_type): New structure to keep nested receive-case
7204 (build_chill_receive_case_start, build_chill_receive_case_end):
7208 Fri Sep 24 04:19:15 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7210 * ch-tasking.c (build_chill_receive_case_start): `namedecl'
7211 should be a _DECL, not an IDENTIFIER_NODE.

7215 * ch-decl.c (find_implied_types): Handle VAR_DECLs.

7224 of ranges, not just once.
7225 * ch-typeck.c (chill_root_resulting_mode), ch-tree.h: New function.
7226 * ch-typeck.c (layout_chill_rang_type): Re-do type-checking

7233 Changes to store in the new DECL_SEIZEFILE field each seize
7234 ALIAS_DECL the name in the most recent use_seize_file directive.
7235 (This requires that use_seize_file directives written to the
7236 grant file be written before the SEIZEs that need it.)
7237 Allow clashing declarations granted into the global scope
7238 (produce a warning), but remember the seizefile case from
7239 (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
7240 The a SEIZE will select the granted decl that matches its
7241 DECL_SEIZEFILE (in other words: grants from the most recent
7242 use_seize_file will be preferred).
7243 * ch-tree.h (DECL_SEIZEFILE), ch-tree.def: New macro.
7244 * ch-tree.h (global_value, IDENTIFIER_GLOBAL_VALUE): Renamed
7245 to outer_value, IDENTIFIER_OUTER_VALUE.
7246 Changes to cause the use_seize_file directives to be written
7247 out in order as they're seen in source.
7248 * ch-lex.l (files_to_seize, next_file_to_seize, last_file_to_seize):
7249 Changed to have type TREE_LIST of pointer to IDENTIFIER_NODE.
7250 * ch-lex.l (handle_use_seizefile_directive): Modify appropriately.
7251 Don't call grant_use_seizefile.
7252 * ch-lex.l (mark_use_seizefile_written): New function.
7253 * ch-grant.c (decode_decl): Write out use_seize_file directive,
7254 if needed, before writing a seize declarations.
7255 * ch-decl.c (pop_module): Handle decls granted into the global
7256 module specially, setting IDENTIFIER_OUTER_VALUE.
7257 * ch-decl.c (lookup_name_for_seizing): Check IDENTIFIER_OUTER_VALUE.
7259 Thu Sep 23 19:05:37 1993 Bill Cox (bill@cygnus.com)
7261 * ch-decl.c (push_chill_extern_process): Delete unused variables,
7262 declare the process' tasking_code variable as external.
7263 * ch-parse.y (process): Force ignore_exprs to FALSE while parsing
7265 * ch-tasking.c (sigdef): Move resetting of quasi_signal from here
7267 * ch-tree.h: Add prototype.
7268 * expr.c (store_constructor): Emergency first-aid. Rewrite later.

7272 * ch-expr.c (build_chill_function_call): Move possible call to
7273 chill_start_module_code until we know we're not calling a builtin.
7274 * ch-decl.c (save_expr_under_name): Use pushdecllist,
7275 not proclaim_decl (which provide for popping the decl).
7276 * ch-parse.y (optname): Also allow TYPENAME.
7278 Thu Sep 23 09:18:35 1993 Bill Cox (bill@cygnus.com)
7280 * ch-decl.c (print_lang_decl): Make weak name output more standard.
7281 (print_lang_identifier): Make signal-data flag output more standard.
7282 (push_chill_extern_process): Pass correct arg tree to
7283 push_chill_extern_function.

7306 * ch-grant.c (print_struct): Add missing loop for tag_list.
7307 (print_struct): Look for variant fields by checking for a
7308 UNION_TYPE, not a NULL name, since we must use a dummy name.
7309 * ch-parse.y (structured_variable): Various fixing.
7310 * ch-decl.c (shadow_record_fields): Rename arg decl -> struct_val.
7312 * ch-satisfy.c (safe_satisfy_decl): Disable copying of modes
7313 for NEWMODE (and hence novelty checking), until we figure out
7316 * ch-except.c (finish_handler_array): Use null_pointer_node,

7328 New functions. Handle 2-pass and variant records.
7329 * ch-parse.y (primval DOT name): Use instead of build_component_ref.

7340 * ch-decl.c (grok_chill_variantdefs): Now return a FIELD_DECL
7341 rather than just its type.

7348 Support multiple tag fields.
7350 * ch-convert.c (remove_tree_element, digest_structure_tuple):
7351 New functions, to digest structure tuples, without calling the

7375 doing the type's layout.
7376 (processpar): Use paramnamelist, but reformat it into a

7491 decl_seen_p, processed_decls, allocated, nr_decls): Removed
7492 no-longer-useful functions and variables that used to guard

8036 Use to print out GRANT and SEIZE statements.
8037 * ch-decl.c (ALL_POSTFIX): New global variable.
8038 * ch-decl.c (bind_saved_names, pop_module): Change to use new
8039 ALIAS_DECL layout, and support general prefix rename and ALL.

8041 * ch-parse.y (build_prefix_clause): New function (handle PREFIXED).
8042 * ch-parse.y (optprogendname, optname): Rename to opt_end_label.
8043 * ch-parse.y: Add support for compound name strings, but defer

8045 Howver, do use defining_occurrence where appropriate.
8046 * ch-parse.y: Re-write syntax and semantics of GRANT and SEIZE
8047 statements to support Blue Book functionality. Neato!

9848 function, for external and seized function declarations.
9849 Make sure to use permanent obstack.
9850 * ch-parse.y (quasi_pdef, extprocedure): Use new function.
9852 * ch-grant.c (chill_finish_module_code): Since module

9857 to end of parameter types list.
9859 * ch-grant.c (chill_start_module_code): Make sure module

9932 (compiler_directive): Replaced by equal_number. Now the only
9933 recursive call to yylex happens in check_newline at the beginning
9936 Sat Apr 10 09:55:50 1993 Bill Cox (bill@rtl.cygnus.com)
9938 * ch-actions.c (build_chill_case_expr): Added from ch-parse.y.
9939 * ch-lex.l (ENTRY, PERVASIVE, ROW, STEP): Add token recognition to

9944 * ch-tree.h (build_chill_case_expr): Add prototype.
9945 * ch-typeck.c (build_chill_cast): Allow untyped_expr - just assign the

10077 Fri Apr 2 21:55:14 1993 Per Bothner (bothner@rtl.cygnus.com)
10079 Major re-write of New module/seize/grant stuff.
10080 Now, a grantfile is a spec module and contains all the
10081 top-level declarations of the granting module, not just
10082 those that are granted. It also contains explicit grant
10083 statments naming those declared names that are granted.
10084 It also has seize statements and use_seize_file directives
10085 to correctly handle transitive dependencies.
10087 * ch-parse.y: Change to allow multiple modules per source file.
10088 Allow spec modules (including quasi definitions) as well as
10090 Allow spec modules inside normal modules; these behave as if
10091 they were outermost. This violates the Blue Book, but is
10092 needed by the new grantfile mechanism. (A grant file is a
10093 spec module that gets included by the use_seize_file directive.)
10094 * ch-parse.y (struct module *current_module, push_module,
10095 pop_module): Support module nesting (for spec modules only).
10097 * ch-tree.h (struct module): New.
10098 * ch-grant.c (granted_decls): New list of declarations
10099 that have been granted into the outermode pseudo-module.
10100 * ch-grant.c (decode_mode): If the decl has a name,
10101 always write the name, not just if the decl has already
10102 been written. Since we write out all decls, we can assume
10103 it will be written later, and depend on the forward
10104 declaration kludges to catch it.
10105 * ch-grant.c (decode_decl): Don't write out _EXTERN.
10106 Instead write out standard (Blue Book) quasi-definitions.
10107 * ch-grant.c (push_granted): New function.
10108 * ch-grant.c (seize_implied_names): New function. Re-write
10109 how set element names are seized when a set type is seized.
10110 * ch-grant.c (chill_seize): Work by seraching the
10111 granted_decls list and copying the declaration.
10112 * ch-grant.c (chill_grant): Write all declarations
10113 declared in this module. Write GRANT statements for
10114 those granted. seize statements for decls seized from
10115 other modules. Write extra syntax to make a complete
10117 * ch-grant.c (grant_use_seizefile): Copy use_seize_file
10118 directives into grant file.
10119 * ch-lex.l (setup_seizefile_read): Call grant_use_seizefile.
10121 * ch-lex.l (struct input_state, current_input_state,
10122 push_input_file, pop_input_file): New (type, variable,
10123 function*2). Used to save and restore state on an input file.
10124 * ch-lex.l: Clean up to handle nested input seizefiles
10125 (needed by new grant/seize mechanism.
10126 * ch-lex.l (skip_to_end_of_directive): New function.
10127 * ch-lex.l (compiler_directive: USE_SEIZE_FILE): Make sure
10128 we skip to the end of the directive *before* we switch
10130 * ch-lex.l (setup_seizefile_read): Prevent reading the
10131 same seizefile twice (otherwise likely with new grant/seize).
10132 * ch-lex.l: Recognize SPEC. Misc cleanups.
10134 * ch-parse.y: Fixed foreward references of types.
10135 Removed the unknown_type_node crock.
10136 * ch-decl.c: Remove all uses of unknown_type_node.
10137 Check for TYPE_SIZE zero instead.
10138 * ch-decl.c (fixup_unknown_type): Make sure new mode
10139 gets copied into old mode. Merge their variant chains.
10140 * c-decl.c (lookup_name_current_level): Make non-static.
10141 * ch-decl.c (lookup_name_current_level): No longer needed.
10143 * ch-parse.y (call): Allow an implicitly defined function
10144 name following the CALL keyword.
10145 * ch-tree.h (struct lang_identifier): Add implicit_decl,
10146 and make sure order of fields matches c-tree.h.
10148 * ch-actions.c (lang_init, build_allocate_memory_call,
10149 build_allocate_globals_memory_call): Fix names (add initial '_')
10150 and prototypes of _allocate_[global_]memory (2nd param is ref).
10151 Use build_chill_function_call, not build_function_call,
10152 so the reference parameter gets handled.
10153 * ch-actions.c. (lang_init): Make sure boolean_{true,false}_node
10154 have boolean_type_node as their types.
10155 * ch-actions.c (build_chill_lower, build_chill_upper): Fix to
10156 work for arrays with BOOLEAN_TYPE ranges (and simplify some).
10158 * ch-except.c: Make sure an end_label is generated,
10159 and jump to it if there is no exception.
10161 * ch-convert.c (convert_to_reference): Strip off NOP_EXPR casts.
10162 * expr.c (expand_expr): Handle NOP_EXPR as Chill-style casts.
10163 (Need cleaning up and FSF installation!)
10164 * ch-parse.y: If taking the address of a cast, move the
10165 ADDR_EXPR inside the NOP_EXPR.
10167 * ch-typeck.c (my_build_array_ref): Simplified, more suitable
10168 versions of build_array_ref from c-decl.c. (E.g. don't barf
10169 if index type is char or bool.)
10170 * ch-typeck.c (build_chill_array_ref): Use my_build_array-ref.
10172 * ch-typech.c (build_chill_bin_type): New function.
10173 Support BIN(N) range type specification.
10174 * ch-parse.y (mode2), ch-lex.l: Recognize BIN(N).
10176 * ch-tree.h (CH_SIMILAR): Redefine in terms of chill_similar.
10177 * ch-typeck.c (chill_similar): New function. Recognize that
10178 that range types are similar to their parent types.
10180 * ch-tree.h: Declare flag_local_loop_counter.
10181 * ch-loop.c: Whether the loop variable is local to the loop
10182 in now controlled by flag_local_loop_counter, instead of
10183 #ifdef'd on CREATE_SCOPE.
10184 * ch-actions.c (lang_decode_option): Recognize flags
10185 "-f[no-]local-loop-counter".
10186 * toplev.c (lang_options): Add Chill flags -f[no-]local-loop-counter.
10188 * varasm.c (make_function_rtl): Due to problems with forward
10189 references, don't rename nested functions in Chill. (Kudge!)
10191 Sun Mar 28 10:12:45 1993 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10193 * ch-lex.l (push_back, readstring): Fix prototypes.

10204 * ch-parse.y (get_type_of): Add function to deal with possible fwd
10205 declared type name. Call it from lotsa places. Add lotsa checks

10215 as-yet-undeclared types. Check for IDENTIFIER_NODE, lookup its
10216 DECL if there, pass TREE_TYPE of decl to build_pointer_type.
10217 (variantfields, varianthack): Clean up.
10218 (variantfield): Check for IDENTIFIER_NODE, lookup its DECL if
10219 there, pass TREE_TYPE of decl to grok_fixedfields.
10220 (labellist): Explicitly assign error_mark_node to signal error.
10221 * ch-typeck.c (chill_compatible): Report FALSE for bad parameters,

10259 * ch-lang.c (finish_chill_enum): Don't allocate a dummy
10260 TYPE_DECL for the enum. I don't think it is needed (?),

10299 vents seg fault when only WITH operand is invalid.
10300 * ch-parse.y (label_spec): Correct assignment within IF expression which
10301 was intended to be equality test. Remove unused variables.
10302 * ch-tree.h: Add prototype. Remove unused EXCP_CODE enumeration, and
10303 prototyping editorial comments.
10304 * ch-typeck.c: Disable generation of code to validate array index for
10305 now. Should be done as a call-back from more generic array_ref code.

10459 * ch-loop.c: Make CREATE_SCOPE #define to enable creation of a new scope
10460 for each CHILL loop, as Z.200 requires. Add powerset and error flags
10461 to loop structure. Evaluate user's powerset expression into a temp,
10462 scan it destructively with __ffsetclrpowerset or __flsetclrpowerset
10463 for powerset loop. Only do loop-end assignments if NOT a powerset
10464 loop, which has much less overhead now.

10682 * ch-lex.l (convert_bitstring), Changed SET_TYPE_CONSTRUCTOR to
10683 take a list of elements which are in the set. This corresponds
10684 better to the tuple input form in Chill (and Pascal).
10685 * varasm.c (unpack_set_constructor, pack_set_constructor):
10686 New functions, to expand SET_TYPE CONSTRUCTORs.
10687 * varasm.c (output_constructor): Use pack_set_constructor
10688 to assemble a SET_TYPE constant from a CONSTRUCTOR.
10690 * ch-grant.c (decode_constant): Better grant for strings,
10691 enumeral, and bitstring constants.
10692 * ch-grant.c: Fixes in seize to avoid duplicates, and emit
10693 things in the correct order.
10694 * c-typeck.c (chill_initializer_constant_valid_p): Kludge
10695 needed to export a static function.
10696 * ch-typeck.c (convert): Avoid needlessly (and lossingly) calling
10697 chill_expand_tuple to convert fix string to varying.
10698 * ch-actions.c (build_chill_binary_op): Promote short
10699 integer operands if needed (otherwise emit routines barf).
10700 * ch-tree.h (SET_WORD_SIZE): New macro.
10701 * ch-parse.y: Fix syntax for RECEIVE CASE.
10702 * ch-parse.y (location): If IDENTIFIER is a CONST_DECL

10719 chill_integer_type_node. Rewrite _max and _min routines,
10720 redefine the signatures for those runtime routines. Move
10721 empty-set check into runtime.
10722 * ch-expr.c, ch-loop.c, ch-process.c, ch-tree.c, ch-typeck.c: change
10723 most integer_type_node references to chill_integer_type_node.

10728 * ch-parse.y: Add working exception handling support.
10729 * ch-lex.l, ch-parse.y: Prefer standard type terminology
10730 (BOOLS, CHARS) even though non-standard (BITS, CHAR) is ok.
10731 * ch-grant.c: Fix various problems related to granting
10732 types such as bitsets.
10733 * ch-tree.c (build_bitstring_type): Set TYPE_MIN_VALUE

10737 * ch-tree.h, ch-actions.c (lang_init), ch-grant.c (decode_mode):
10738 Undo kludge where integer_type_node was hardwired to 16 bits.
10739 Make integer_type_node etc have the same size as in cc1.
10740 New types chill_integer_type_node and chill_unsigned_type_node
10741 that correspond to the Chill source types INT and UINT.
10742 For now, these match the C 'short' types, but that should
10743 become a configuration option later,
10745 Tue Feb 9 11:41:25 1993 Bill Cox (bill@rtl.cygnus.com)
10747 * ch-actions.c (build_chill_unary_op): allow NOT of a set.
10749 Tue Feb 9 08:27:18 1993 Bill Cox (bill@rtl.cygnus.com)

10754 * ch-loop.c (begin_chill_loop, end_chill_loop): remove
10755 emit_nop() calls - they now (since exceptions) cause seg faults.

10758 * ch-tree.h: remove prototypes added to c-tree.h.
10759 * ch-typeck.c (build_chill_array_ref): correct getting domain

10763 Sun Feb 7 18:20:49 1993 Bill Cox (bill@rtl.cygnus.com)
10765 * ch-tree.def: add a new tree type - just for varying array
10766 references. We were using ARRAY_REF, but the underlying C
10767 code also generates that one.
10768 * ch-convert.c, ch-expr.c, ch-typeck.c: use the new tree type.
10770 Sun Feb 7 17:33:17 1993 Bill Cox (bill@rtl.cygnus.com)

10834 smaller actions directly (maybe_array_ref() used to call them).
10835 * ch-tree.h: add build_chill_function_call, build_chill_slice
10836 * ch-typeck.c: add build_chill_slice()

10997 * dwarfout.c (output_type): Add hack that matches the one in the
10998 chill front end to distinquish between true string types and
10999 arrays of char, since it uses ARRAY_TYPE for both, rather than
11000 trying to use the existing support for STRING_TYPE.

11062 * chill.gperf, ch-hash.h: add Wilfried's tokens
11063 * ch-lex.l: fold in Wilfried's changes. Some tokens

11108 function __builtin_setbitinstring.
11109 * ch-expr.c (chill_expand_assignmment): Special-case handling
11110 for BIT_FIELD_REF with non-constant bit position (which is
11111 not yet handled by expand_expr).

11125 * ch-actions.c: define sizetype for everyone, use it to build
11127 * ch-parse.y: tiny cleanup.
11129 Wed Jan 6 13:25:33 1993 Bill Cox (bill@cygnus.com)
11131 * modules: use gdb rather than naked-gdb, to get opcodes
11132 in chill definition.
11134 Wed Jan 6 09:48:35 1993 Bill Cox (bill@cygnus.com)
11136 * ch-typeck.c: add code to handle references to elements of VARYING
11137 arrays. Simplify chill_give_type_to_expr. Add rough draft of run-
11138 time index checking for VARYING arrays (under #if 0).
11139 * ch-actions.c: new function cond_type_range_exception & calls.
11140 New function cond_range_exception, for more general range-checking.

11142 for the special varying field names.
11143 * ch-tree.h: define macros for varying field names.
11144 * ch-expr.c: use macros for varying struct names. Simplify

11159 Move shared code into ...
11160 * ch-decl.c (start_chill_function): ... here.
11161 * ch-decl.c (start_chill_function): Add missing call to
11162 expand_start_bindings.

11174 Mon Jan 4 17:57:48 1993 Per Bothner (bothner@cygnus.com)
11176 * ch-grant.c, ch-parse.y: Remove all code for explicitly
11177 calling initializer functions. This is not needed, since we
11178 use the same mechanism used for C++ static constructors.
11179 * ch-grant.c (chill_start_module_code): Make sure the
11180 init_name starts with the magic string also used for C++
11181 initializers. Also, don't embed the file name in the name,
11182 just use the module name.
11183 * ch-grant.c (chill_finish_module_code): Now that the
11184 initializer name follows the standard 'collect' convention,
11185 don't need to call assembler_constructor_alias, but can
11186 use the standard assemble_constructor instead.
11187 * varasm.c (assemble_constructor_alias): Remove no-longer-
11189 * ch-parse.y: Move code that is common to the beginning of
11190 all functions to a new macro INIT_ACTION.
11191 Make sure INIT_ACTION is also done for callaction, fixing a bug.
11192 * ch-parse.y (INIT_ACTION): Do chill_start_module_code()
11193 before emit_line_note(), not after.
11195 Mon Jan 4 11:43:12 1993 Bill Cox (bill@cygnus.com)
11197 * ch-parse.y: restore requirement for :upper-bound in array decl.
11198 * ch-actions.c: enhance upper, lower, length functions for VARYING.
11200 Mon Jan 4 09:28:44 1993 Bill Cox (bill@cygnus.com)

11207 * ch-lex.l: better compiler-directive error messages,
11208 allow underscores in exponents
11209 * ch-loop.c: prevent passing NULL ptr to printf
11211 Sun Jan 3 11:57:13 1993 Bill Cox (bill@cygnus.com)

11215 Sun Jan 3 11:36:39 1993 Bill Cox (bill@cygnus.com)
11217 * ch-parse.y: define IGNORED_DIRECTIVE
11218 * ch-typeck.c: subtract array's lower domain value, even if
11219 index expression is constant.

11223 * ch-lex.l (convert_float): Fix misspelling in error message.
11225 Sat Jan 2 16:02:16 1993 Per Bothner (bothner@rtl.cygnus.com)
11227 * Makefile.in: Took out chill-runtime support.
11228 Chill run times are now in ../chillrt, not ./chillrt.p
11230 Sat Jan 2 15:04:13 1993 Bill Cox (bill@cygnus.com)
11232 * ch-hash.h, chill.gperf: cleanup. fewer keywords seen by ch-parse.y.
11234 Sat Jan 2 13:27:49 1993 Per Bothner (bothner@rtl.cygnus.com)
11236 * ch-lex.l (check_newline): Use the orginal versions (derived
11237 from the C code, not the simplified, special-case version).
11238 Also, fix that version of check_newline to not call yylex()
11240 * ch-lex.l (yy_input): Call check_newline to handle
11241 newlines and check for # directives.
11242 * ch-lex.l (syntax): Don't recognize #-directives; these
11243 are now handled by check_newline.
11244 * ch-actions.c (lang_init): Call the modified version of
11245 check_newline(). Do this at the *after* we've initialized
11246 standard types, so this can be done while lineno is still 0.
11248 Sat Jan 2 10:57:20 1993 Bill Cox (bill@cygnus.com)
11250 * ch-hash.h, chill.gperf: add remaining reserved words.
11252 Sat Jan 2 09:59:55 1993 Bill Cox (bill@cygnus.com)
11254 * ch-tree.h, ch-parse.y, ch-lex.l: add remaining reserved words,
11255 names for exceptions
11257 Fri Jan 1 12:30:31 1993 Fred Fish (fnf@cygnus.com)
11259 * ch-tree.h (JOINER): Define joiner character the same way
11261 * ch-grant.c (chill_start_module_code): Use JOINER character
11262 to implement name mangling for the initializer function name.
11263 Algorithm is designed to be simple, distinct from C++ mangled
11264 symbols, and easy to convert to demangled form.
11266 Thu Dec 31 10:30:51 1992 Bill Cox (bill@rtl.cygnus.com)
11268 * ch-expr.c: make array assignments work with indirect refs.
11269 * ch-actions.c: prepare for array parameter handling.
11270 * ch-loop.c, ch-parse.y, ch-tree.def, ch-typeck.c: clean up.
11272 Thu Dec 31 15:29:20 1992 Per Bothner (bothner@rtl.cygnus.com)
11274 * ch-lex.l (yy_input): Re-write to return more than one
11275 character at a time (execpt when reading seize-files).
11276 Don't increment lineno until we start reading the next line.
11277 This fixes some off-by-one errors in lineno.
11279 Wed Dec 30 16:15:23 1992 Per Bothner (bothner@rtl.cygnus.com)
11281 * ch-convert.c: Assume use of new common.c.
11282 * ch-convert.c (convert_to_reference, convert_from_reference):
11283 New routines, to handle loc-identity declared variables and
11284 LOC parameters (both of which are implemented as references).
11285 * ch-lang.c (convert_to_boolean, convert_to_char): Move to
11286 ch-convert.c, where they would seem to belong.
11287 * ch-convert.c (convert): New function, since we no longer
11288 link in c-convert.c.
11289 * ch-expr.c (chill_expand_assignment): Handle by calling
11290 convert() instead of chill_comptypes().
11291 Also handle the LHS being a reference.
11292 * ch-parse.y: Add a procedure call as an action.
11293 * ch-parse.y (locdec, optlocinit): Move handling of
11294 loc-identity declarations from optlocinit to locdec
11295 - and add working semantics for it.
11296 * ch-parse.y (seizestatement, visibilty_stmt): Simplify.
11297 * ch-parse.y (grantstatement etc): Don't bother making list.
11298 * ch-lex.l: #include <sys/types.h> before <sys/stat.h>.
11300 Wed Dec 30 16:06:55 1992 Bill Cox (bill@rtl.cygnus.com)
11302 * ch-parse.y, ch-expr.c: add support for declaring & assigning
11304 * ch-typeck.c: allow VARYING structures in assign_type_to_expr.
11306 Tue Dec 29 15:28:48 1992 Bill Cox (bill@cygnus.com)
11308 * ch-actions.c: implement expressions of arrays of char,
11309 ( concatenation, relationals ), correct type of code parameters
11310 * ch-expr.c: correct type of code parameters
11312 Tue Dec 29 11:16:19 1992 Bill Cox (bill@cygnus.com)
11314 * ch-decl.c: cleanup.
11315 * ch-parse.y: put emit_line_note() calls in lotsa places,
11316 per Fred's request; be sure that statements get counted also.
11317 * ch-lex.l: standardize function headers.
11319 Tue Dec 29 10:41:56 1992 Fred Fish (fnf@cygnus.com)
11321 * ch-decl.c (start_chill_function): Always return 1, rather
11322 than a random value.
11323 * ch-lex.l (check_newline): Add a version for chill that
11324 just snarfs the right value for main_input_filename out of
11325 the first line of the input file, without disturbing the
11326 lexer state or requiring it's assistance.
11327 * ch-actions.c (lang_init): Call check_newline, like the
11328 other language frontends, to get main_input_filename set
11329 from first line of input file.
11331 Mon Dec 28 18:49:01 1992 Bill Cox (bill@cygnus.com)
11333 * ch-parse.y: clean up conflicts. The remaining one is
11336 Mon Dec 28 17:28:40 1992 Bill Cox (bill@cygnus.com)
11338 * ch-parse.y, ch-lex.l, ch-actions.c: add stubs for I/O,
11339 clean up some parser conflicts.
11341 Mon Dec 28 15:00:20 1992 Bill Cox (bill@cygnus.com)
11343 * ch-parse.y, ch-lex.l: add keywords and parsing for most of
11346 Sat Dec 26 20:48:23 1992 Fred Fish (fnf@cygnus.com)
11348 * chillrt/chillrt0.c: Oops, SVR4 doesn't need leading '_'
11349 on build_exceptions.
11351 Sat Dec 26 11:00:36 1992 Fred Fish (fnf@cygnus.com)
11353 * ch-grant.c (chill_finish_module_code): Call
11354 assemble_constructor_alias rather than assemble_constructor.
11355 * varasm.c (assemble_constructor_alias): New function,
11356 like assemble_constructor, but also handles the case where
11357 ASM_OUTPUT_CONSTRUCTOR is not defined and GNU ld is not
11358 being used. Emits a symbol table alias name with the correct
11359 prefix for collect to find and add to the __CTOR_LIST__.
11360 * chillrt/chillrt0.c: Build on previous hack that gets
11361 _build_exceptions into the __CTOR_LIST__, to make it work
11362 for both the non GNU-ld case and for the SVR4 case.
11364 Tue Dec 22 18:24:55 1992 Bill Cox (bill@cygnus.com)
11366 * ch-loop.c: clean up location enumeration - one more

11380 ch-loop.c: rough draft of location enumeration
11381 ch-lex.l, ch-expr.c, ch-decl.c: minor cleanup
11382 ch-actions.c: finish making pred() and succ() work.
11384 Mon Dec 21 10:04:35 1992 Bill Cox (bill@cygnus.com)
11386 * ch-actions.c: allow pred(char) and succ(char).
11388 Sun Dec 20 16:04:28 1992 Bill Cox (bill@cygnus.com)
11390 * ch-expr.c, ch-actions.c, ch-parse.y, ch-loop.c,
11391 c-expr.c: make DO WITH work.
11393 Sun Dec 20 12:22:53 1992 Bill Cox (bill@cygnus.com)
11395 * ch-loop.c, ch-actions.c, ch-typeck.c: powerset loops
11398 Sat Dec 19 14:20:23 1992 Per Bothner (bothner@cygnus.com)
11400 * c-typeck.c (process_init_constructor): Add warning if
11401 there is a duplicate default initializer element.
11402 * ch-typeck.c (chill_give_type_to_expr): New function,
11403 to handle coercion of an expression to context-given type,
11404 Takes care of untyped tuples, and case expressions.
11405 * ch-decl.c (do_decls), ch-typeck.c (chill_expand_return,
11406 chill_expand_result), ch-parse.y <assignaction>:
11407 Use chill_give_type_to_expr().
11408 * ch-typeck.c (chill_handle_case_label): New parameter list,
11409 to handle the (new) conventions for <case_label>, including
11410 default elements and ranges.
11411 * ch-parse.y <expanded_case_label>, ch-typeck.c
11412 (expand_case_expr): Use new version of chill_handle_case_label.
11413 * ch-decl.c (push_syndecls): Change parameters: Instead of
11414 TREE_LIST representing a compete <synonym definition statement>,
11415 just pass the parts of a single <synonym definition> as 3
11416 different parameters. Also, use chill_give_type_to_expr(),
11417 to handle untyped tuples in the RHS.
11418 * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct
11419 a tree - just call push_syndecls() on each <synonum_definition>
11421 * ch-parse.y (exprlist_get_single): Remove; no longer needed.
11422 * ch-parse.y: Handle <tuple> without mode name diferently from
11423 <tuple> with mode name. The latter is a <primval> that can be
11424 in most contexts, but if the <mode name> is missing, the <tuple>
11425 is only allowed in certain contexts. Use the new non-terminal
11426 <untyped_expr> to indicate those contexts where untyped tuples
11427 (and case expressions) are valid because the expression gets a
11428 type from its context (such as the RHS of an assignment).
11429 Use chill_give_type_to_expr in those contexts.
11431 Sat Dec 19 14:01:26 1992 Bill Cox (bill@cygnus.com)
11433 * ch-actions.c, ch-loop.c, Makefile.in: looping stuff.
11435 Sat Dec 19 10:16:20 1992 Bill Cox (bill@cygnus.com)
11437 * ch-parse.y: clean up warning messages from byacc. bison
11438 still complains thrice.
11440 Fri Dec 18 12:33:29 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11442 * ch-actions.c (maybe_chill_comptypes): Delete unused
11444 (chill_comptypes): Add new parameter ERRSTR. All callers
11446 (build_chill_binary_op): Fix indentation to match GNU coding
11449 Fri Dec 18 08:18:13 1992 Bill Cox (bill@rtl.cygnus.com)
11451 * ch-parse.y, ch-expr.c, ch-actions.c, expr.c: major

11461 a default initializer element.
11462 * ch-parse.y: Implement default elements for tuples
11463 (as in '(else):' and '(*):' ).
11465 * ch-parse.y: Previous change to dis-ambiguate case-labels
11466 seems to have allowed getting rid of all of the expr_or_list hair.
11467 * ch-decl.c (do_decls): Undo Tiemann's change to "Handle
11468 initialization of multiple variables by a tuple" - the
11471 Wed Dec 16 11:17:53 1992 Bill Cox (bill@cygnus.com)
11473 * ch-parse.y: complete re-write of DO statement handling.
11474 now operational, except WITH is stubbed out. Improved
11475 syntax error message.
11476 * ch-actions.c: DO support: high_domain_value(), low_domain_value ().
11477 * ch-expr.c: fixes to IN_EXPR handling.
11479 Tue Dec 15 17:15:13 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11481 * ch-grant.c: Add casts to alloca return to avoid compiler warning.
11482 * ch-lex.c: Likewise.
11484 * Makefile.in (ch-lex.c): Delete incorrect free declaration added
11485 by flex to avoid compiler error.
11487 Tue Dec 15 08:41:08 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11489 * ch-decl.c (do_decls): Handle initialization of multiple
11490 variables by a tuple.
11492 * ch-decl.c (do_decls,start_chill_function): Make DECL public
11493 if we're doing a GRANT ALL at top level.
11495 * ch-lang.c (build_range_type): Deal with typecast to CHAR in
11498 * c-typeck.c (digest_init): SET_TYPE is not a scalar type.
11499 BOOLEAN_TYPE and CHAR_TYPE are scalar types.
11501 Mon Dec 14 14:58:32 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11503 * ch-lex.l (get_chill_{linenumber,filename}): New functions.
11504 (convert_number): Use LONG_TYPE_NODE instead of INTEGER_TYPE_NODE.
11506 Mon Dec 14 13:36:44 1992 Bill Cox (bill@cygnus.com)
11508 * expr.c: install and test newer Pascal IN_EXPR code,
11509 but don't activate it - it's very verbose.
11511 Mon Dec 14 00:22:49 1992 Fred Fish (fnf@cygnus.com)
11513 * Makefile.in (LANGUAGES): Add chill.
11514 * Makefile.in (CHILL_INSTALL_NAME, CHILL_CROSS_NAME):
11515 New macros for chill native and cross installation names.
11516 * Makefile.in (COMPILERS): Add cc1chill.
11517 * Makefile.in (CHILL_OBJS): New macro, chill objects.
11518 * Makefile.in (CHILL_TREE_H): New macro, chill headers.
11519 * Makefile.in (CHILL, chill, cc1chill, chill-runtime, libchill.a,
11520 sublibchill.a, ch-parse.o, ch-parse.c ch-*.o, install-libchill,
11521 install-librmt): New targets.
11522 * Makefile.in (install-native): Add install-libchill,
11525 Sun Dec 13 15:21:06 1992 Bill Cox (bill@cygnus.com)
11527 * ch-actions.c, ch-expr.c: Fix the pop-count in library calls.
11529 Sun Dec 13 14:07:32 1992 Bill Cox (bill@cygnus.com)
11531 * ch-actions.c: fix unary operations, modulus ops,
11532 (discovered after extending regression tests).
11534 Sun Dec 13 12:16:32 1992 Bill Cox (bill@cygnus.com)
11536 * resync with Michael and Wilfried
11538 Sun Dec 13 09:11:25 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11540 * ch-parse.y (output_constant): Fixed some whitespace
11542 * ch-tree.h: Add declarations for new chill functions that
11543 have been implemented but not (yet) declared.
11545 Sat Dec 12 00:17:23 1992 Per Bothner (bothner@cygnus.com)
11547 * c-typeck.c (process_init_constructor): Warn about duplicate
11548 labels for labelled initializer elements.
11549 * ch-lex.l (various operator tokens, such as "+"): Don't
11550 set yylval.code to a TREE_CODE; this is better done in parser.
11551 * ch-parse.y: Some work with case labels and tuples.
11552 Get literal range as tuple (and case) labels working.
11553 Fix some problems introduced by recent grammar overhaul.
11555 Fri Dec 11 13:28:48 1992 Bill Cox (bill@cygnus.com)
11557 * ch-actions.c, ch-parse.y ch-tree.h ch-expr.c, ch-typeck.c:
11558 got long, real expressions working. We can also call a func-
11559 tion and use its return value.
11561 Thu Dec 10 14:45:17 1992 Per Bothner (bothner@cygnus.com)
11563 * ch-parse.y: Major change to remove or at least identify
11564 parser ambiguities. One result: We now allow actions that
11565 start with '(', as required by teh Blue Book. This does break
11566 some things; look for FIXME for things that need work.
11567 * ch-typeck.c (chill_expand_case_expr): We need an extra
11568 level of looping to (in the future) support <case label
11569 specification>s with more than one <case label list>.

11593 on arrays of BOOLs.
11595 Mon Dec 7 08:55:20 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11597 * ch-actions.c (lang_init): Set LINENO to 1 at beginning to
11598 indicate we are done with initialization.
11600 * ch-decl.c (do_decls): Set TREE_PUBLIC if we are doing a
11602 (start_chill_function): Ditto.
11604 * ch-lex.c (convert_bitstring): Set TREE_CONSTANT.

11621 * tree.def: Move CARD_EXPR and SET_LE_EXPR back down with the other
11622 Pascal-required ones, since C++ no longer needs them. When
11623 Chill's public, a comment can be added to the effect that

11667 (push_newmode,push_synmode): Call `fixup_unknown_type' when we
11668 see a declaration that uses `unknown_type_node'. FIXME.
11670 * ch-grant.c (decode_constant): New function.
11671 (decode_decl): Call `decode_constant' for CONST_DECLs.
11673 * ch-lex.l (char action): Use ridpointers instead of
11674 lookup_name to get "char"'s declaration.
11676 * ch-parse.y: Call `build_lang_decl' instead of `build_decl'
11677 when we need to build a TYPE_DECL.
11679 Tue Dec 2 09:44:05 1992 Bill Cox (bill@cygnus.com)
11681 * ch-typeck.c: clean up a gcc warning with a forward
11682 declaration of build_string_type.

11687 that are duplicated in c-decl.c
11689 Tue Dec 1 16:38:51 1992 Fred Fish (fnf@cygnus.com)
11691 * ch-actions.c (lang_init): Ifdef out initializations for
11692 __builtin_abs and __builtin_fabs, since they are duplicates of
11693 initializations in c-decl.c, and trigger spurious warnings.
11695 Tue Dec 1 16:35:18 1992 Bill Cox (bill@cygnus.com)
11697 * ch-parse.y: make size() work with a typename argument.

11724 Mon Nov 30 17:35:33 1992 Fred Fish (fnf@cygnus.com)
11726 * chillsh: New script frontend (ala g++), installed as "chill".
11727 Can't be called "chill.sh" because make tries to cat it into the
11728 "chill" directory. Can't be called just "chill" cause that's
11729 already there as a directory.
11730 * Makefile.in: Add rules to install chillsh as "chill".
11731 * chill/libchill.c: Temporarily ifdef out stuff that wants
11732 to conflict with i486/SVR4 runtime or wants to pull in librmt.a,
11733 which itself causes linkage to fail.

11737 * ch-lex.l: added keywords for TRUNC, ROUND, FLOAT, LFLOAT
11738 conversion routines.
11739 * ch-parse.y: added %tokens for TRUNC, ROUND, FLOAT, LFLOAT.
11740 Added production for SIZE(expr).

11745 * ch-lex.l, ch-parse.y: Translate token PFEIL into English ARROW.
11746 * ch-parse.y (op6): Remove handling of string repetition operator,
11747 until we can figure out a way to parse it correctly.

11749 * ch-parse.y (tuple): Merge the two variants using optmodename.
11750 * ch-parse.y (location): Add semantic actions for
11751 dereferencing operator ->.

11755 * ch-actions.c: removed compile warning, better code for abs.
11757 * ch-parse.y: add productions for builtin functions succ, pred,
11758 abs, and size. Add %tokens also. Sort %tokens alphabetically.
11760 * ch-lex.l: add parsing for builtin function names, such as abs,
11761 pred, succ, etc. Put flex -a option into Makefile.in, so we can
11762 clean up the lexer soon.

11766 * ch-typeck.c (chill_handle_case_label, chill_handle_case_default):
11767 New functions, for code common to CASE actions and expressions.
11768 * chill.y: Replace some code by calls to chill_handle_case_label
11769 and chill_handle_case_default.
11770 * ch-typeck.c (chill_expand_case_expr): Add semantics.
11772 * tree.c: Change doing_chill_thang from extern to common.
11774 Mon Nov 23 18:34:22 1992 Per Bothner (bothner@rtl.cygnus.com)
11776 * ch-tree.def: New CASE_EXPR type, for case expressions.
11777 * ch-expr.c (chill_expand_expr): Hook for CASE_EXPR.
11778 * ch-typeck.c (chill_expand_case_expr): New function.
11779 Placeholder to implement case expressions.
11780 * ch-typeck.c (chill_expand_result, chill_expand_return):
11781 Handle mode-unspecified tuples and case expressions in
11782 the context of RETURN and RESULT actions.
11783 * chill.y (assignaction): Handle case expressions in the
11784 context of the RHS of an assignment action.
11785 * chill.y (caseaction): Remove spurious duplicate OF in grammar.
11786 * chill.y: Handle labeled structure tuples.
11787 * chill.y: New rules to parse CASE expressions.
11788 * tree.c (build_function_types): Allow Chill functions
11789 to return arrays and functions.
11791 Wed Nov 18 13:50:28 1992 Per Bothner (bothner@rtl.cygnus.com)
11793 * ch-typeck.c (chill_expand_tuple): New function. Expand a
11794 tuple (constructor) given an expected (context) type.
11795 * chill.y: Implement 'LHS := TUPLE' using expand_chill_tuple,
11796 using the mode of the LHS and the expected type of the TUPLE.
11797 * chill.y: Implement initialization.
11798 * chill.y: Fix some syntax bugs (forbidlist must be surrounded
11799 by parentheses), and remove or note ambiguities.
11800 * chill.y: Started converting layout style to be like c-parse.in.
11801 * chill.y: Implement IF expressions.
11802 * chill.y: Added syntax rules for tuples. Labelled and unlabelled
11803 array tuples should now work (in some contexts).
11804 * ch-actions.c: Initialize doing_chill_thang to 1.
11805 * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
11806 initializer, to make pushdecl and finish_decl work.
11807 * c-decl.c (convert_for_assignment): If Chill, don't convert
11808 function and arrays into pointers. (Maybe functions should
11809 still be converted?)
11810 * c-typeck.c (grokdeclarator): Allow functions in Chill
11811 to return arrays and functions.
11813 Mon Nov 16 15:40:47 1992 Per Bothner (bothner@rtl.cygnus.com)
