2964 Tue Oct 25 14:11:07 1994 Per Bothner <bothner@kalessin.cygnus.com>
2966 * convert.c (convert): When converting BOOL constant to
2967 bit-string, bit_one_node and bit_zero_node were switched.
2968 * actions.c (chill_expand_assignment): Use force_addr_of,
2969 not build_chill_addr_expr - latter yields bogus error.
2971 Fri Oct 21 14:26:52 1994 Per Bothner <bothner@kalessin.cygnus.com>
2973 * expr.c (build_chill_indirect_ref): Check for POINTER_TYPE (only)
2974 after converting from REFERENCE_TYPE.
2975 * expr.c (build_compare_expr): Convert to common mode *after*
2976 we've checked compatibility.

3013 * convert.c (convert): Only call digest_array_tuple if ARRAY_TYPE.
3014 * typeck.c (chill_expand_tuple): Print error if type is
3015 neither array, struct, or powerset.
3017 * expr.c (chill_expand_expr cases CONCAT_EXPR, SET_*_EXPR,
3018 UNDEFINED_EXPR): Call preserve_temp_slots for temp targets.
3019 If target is not MEM, make temp (even if not REG) to simplify
3020 - and don't copy original target to temp target first. (Not needed.)
3022 * lang.c (maybe_objc_comptypes): Just return -1.

3031 timing.c, typeck.c: Change build1 (ADDR_EXPR, ptr_type_node, XX)
3032 to force_addr_of (XX). Add call to mark_addressable where needed
3033 for other calls to build 1 (ADDR_EXPR, TYPE, XX).

3052 * expr.c (build_chill_descr): Add missing call to mark_addressable.
3053 * loop.c (toop_loop_end_check): Replace build1 (ADDR_EXPR ...)
3054 with call to force_addr_of (which calls mark_addressable).
3055 * expr.c (build_chill_descr, build_chill_inttime): Likewise.

3096 Give up on trying to use the cleanup mechanism in stmt.c to
3097 make sure the exception handler get unlinked on goto/exit/return.

3161 * lex.l (readstring): Add processing of control sequence
3162 in character string literals. The granting mechanism writes

3182 the entrypoint of a process.
3183 (build_process_header): Change PROCESS arguments to be
3184 like arguments of a function. There will be a wrapper
3185 which is the real entry point for a PROCESS. This wrapper
3186 is automatically build after a PROCESS definition and gets
3187 as argument a pointer to a structure looking like the
3188 arguments of the PROCESS. This wrapper will call the
3189 PROCESS (see build_process_wrapper).
3190 (build_process_wrapper): New function (see above).
3191 (build_start_process): Change processing of arguments.
3192 (tasking_setup): Add processing of a different entry point

3221 * Makefile.in (GNUCHILL_VERSION): Remove it, its defined in
3224 * chill.in: In case of -fgrant-only pass "-S -o /dev/null"
3225 to the compiler to avoid generation of an object file.
3227 Thu Sep 8 12:07:28 1994 Per Bothner (bothner@kalessin.cygnus.com)
3229 * convert.c (display_int_cst), ch-tree.h: New function.
3230 * convert.c (digest_array_tuple): Use digest_int_cst to
3231 provide better error messages. Return error_mark_node on error.
3232 * grant.c (decode_const): Simplify by using digest_int_cst.
3233 * grant.c (format_character, find_assoc): Removed.
3235 * decl.c (do_decl): Add missing TREE_CHAIN.
3237 * decl.c (finish_incomplete_decl): Removed.

3240 array from initialization.
3241 (complete_array_type): Just make it abort.
3243 * except.c (finish_handler_array): Avoid calling C-specific kludge
3244 complete_array_type.
3246 * convert.c (digest_constructor): Rename, and re-write to:
3247 (digest_array_tuple, convert): No longer use the code in
3248 ../c-typeck.c; use a Chill-only implementation (sigh).
3250 * typeck.c (chill_expand_tuple): Remove unneeded call to
3251 complete_array_type.
3253 * expr.c (fold_set_expr), grant.c (decode_constant),
3254 typeck.c (expand_constant_to_buffer): Update name of called
3255 function unpack_set_constructor to get_set_constructor_bits.

3260 * inout.c (build_chill_writetext): Handle 64-bit integer literals
3261 by trying to convert them to a smaller type.
3263 * lex.l (convert_number): Always use long long type (possibly
3264 unsigned) to avoid problems with constant folding truncation.

3268 * ch-tree.h (enum chill_built_in_function): Add BUILT_IN_QUEUE_LENGTH.

3278 Thu Sep 1 15:38:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3280 * lex.l (default_lex): New function. Progress towards
3281 getting rid of [f]lex.
3283 * lex.l (convert_number): Use mul_double and add_double.
3284 Set result type to a reasonable type in which the literal
3285 will fit. Give error message if literal is too big.
3287 * lex.l (equal_number): Switch (temporarily) to permanent obstack.
3289 * typeck.c (build_chill_slice_with_range): Check for empty
3290 slice *after* we have checked for upper/lower limit in range.

3293 CHAR ranges are represented as INTEGER_TYPEs.)
3295 * tasking.c (build_process_header): Add missing call to
3296 expand_start_bindings.
3297 * parse.c (end_function): Add missing expand_end_bindings.

3305 * actions.c (print_missing_cases, check_missing_cases,
3306 BITARRAY_TEST, BITARRAY_SET): New functions and macros,
3307 to check for completeness of case actions and expressions.
3308 * decl.c (c_decode_option, init_decl_processing):
3309 Don't set warn_switch.
3310 * expr.c (chill_expand_case_expr): Call check_missing_cases

3314 * expr.c (build_chill_binary_op): Remove some dead code.
3315 * expr.c (chill_truthvalue_conversion): Call build_chill_binary_op

3333 * tasking.c (build_receive_signal_case_label): Remove backwards
3334 chill_convert_for_assignment (which converted whatever garbage
3335 was in the *target* to the type of the signal argument!).
3337 Fri Aug 19 07:10:43 1994 Wilfried Moser (moser@rtl.cygnus.com)
3339 * inout.c (build_chill_io_list_type, build_enum_tables),
3340 tasking.c (build_tasking_struct): Temporarily reset
3341 maximum_field_alignment to 0, so that the compiler-built
3342 data structures needed by the RTS can be independent of -fpack.
3344 Thu Aug 18 13:39:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3346 * typeck.c (build_init_struct): Temporarily reset
3347 maximum_field_alignment to 0, so that the compiler-built

3352 * parse.c (parse_primval, expect, parse_on_exception_list):

3360 * ch-tree.def (SLICE_EXPR): New tree-code.
3361 * typeck.c (build_chill_slice): For building a slice of a
3362 bit-string, just generate a SLICE_EXPR.
3363 * decl.c (init_decl_processing): Declare __pscpy.
3364 * actions.c (chill_expand_assignment): Handle a SLICE_EXPR
3365 on the LHS of assignment, by calling __pscpy.
3366 * expr.c (chill_expand_expr): Handle SLICE_EXPR (as a RHS
3367 value) by using __psslice to copy slice to a temp.
3369 Wed Aug 17 05:52:44 1994 Wilfried Moser (moser@rtl.cygnus.com)
3371 * Make-lang.in: Change version of GNUCHILL compiler to 1.4.1.
3372 * expr.c (build_chill_length): Enable LENGTH built-in to process
3373 Buffers and Events too (Z.200/1992).
3374 * lex.l (yywrap): Always set yyin to finput and/or grt_in. On
3375 a linux system the previous version was not able to run.
3376 * tasking.c: Correct processing of infinite buffer- and event-length
3377 to avoid RANGEFAIL warning.
3379 Thu Aug 11 11:46:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3381 * parse.c (parse_if_expression_body): Don't call the C-specific
3382 build_conditional_expr. Just do build_nt (COND_EXPR, ...).
3383 * convert.c (convert): Convert a COND_EXPR by converting
3386 * convert.c (convert): Don't call convert before
3387 convert_to_reference. It's apt to do weird and unneedful things.
3388 * convert.c (convert): If the expression is varying, just call
3389 varying_to_slice, which simplifies quite a bit.
3391 * ch-tree.h (varying_to_slice): Add prototype.
3392 * typeck.c (varying_to_slice): Remove prototype.
3394 * satisfy.c (satisfy): Move case PAREN_EXPR from type 'e'
3397 * except.c (emit_setup_handler): Temporarily reset the
3398 maximum_field_alignment to zero so the compiler's exception
3399 data structures can be compatible with the run-time system,
3400 even when we're compiling with -fpack.
3402 * expr.c (compare_records): Call saved_if_needed on operands.
3404 * expr.c (build_set_expr case NE_EXPR): Don't use __nepowerset
3405 which has been reimplemented to just call __eqpowerset and
3406 invert the result. Inline this new implementation by
3407 handling as EQ_EXPR, and inverting the result.
3408 * decl.c (init_decl_processing): Don't define unused __eqpowerset.
3410 * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
3411 type boolean_type_node, not void_type_node. (Fixing this
3412 avoids a crash in the back-end.)
3414 * grant.c (decode_constant): In a CALL_EXPR, if the argument
3415 list is not a TREE_LIST (as in string repetiation), don't
3418 Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3420 * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
3421 CONST_DECL is from a SET definition. (This is safer than
3422 checking that the type is ENUMERAL_TYPE, because synonym
3423 definitions may have a NULL TREE_TYPE.)
3424 Also, if we have duplicate enums whose types are identical,
3426 * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
3427 an extra 'quiet' parameter, which is true if we're called from
3428 bind_sub_modules. (In that case an error message about duplicated
3429 decls would be repeated later, so suppress it.)
3431 * parse.c (stmt_count): Removed, not used.
3432 (INIT_ACTION): Call emit_line_note only if !ignoring.
3433 (parse_begin_end_block): Do INIT_ACTION even if ignoring.

3441 * parse.c (parse_untyped_expr): Fix various problem for the
3442 case that we see a '(': Add missing 'case' keyword.
3443 Only recurse if '(' is followed by 'if', 'case' or '[',
3444 and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
3446 * parse.c (parse_send_action): Remove extra nreverse.
3448 Thu Jul 28 04:00:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3450 * expr.c (build_allocate_global_memory_call, build_allocate_memory_call):
3453 Tue Jul 26 22:48:15 1994 Michael Tiemann (tiemann@blues.cygnus.com)
3455 * parse.c (parse_untyped_expr): Added missing "case" before LPRN.
3456 Added a missing call to `require' as well.
3458 Tue Jul 19 10:30:12 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3460 * lex.l (yywrap): Define as yywrap_chill to avoid conflicts with
3461 the extern declaration in the flex skeleton.
3463 Mon Jul 18 23:06:04 1994 Per Bothner (bothner@kalessin.cygnus.com)
3465 * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
3466 Check the type of the instance expr using CH_COMPATIBLE,
3467 and not just == instance_type_node. (This allows
3468 the expression to have mode READ INSTANCE).
3469 * tasking.c (build_instance_type): Give instance_type_node
3470 a non-null novelty (i.e. different from a struct).
3471 * tasking.c (build_receive_case_start, build_delay_case_start):
3472 Check that for a location using CH_LOCATION_P.
3474 Mon Jul 18 13:22:23 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
3476 * expr.c (finish_chill_unary_op): Use TREE_SET_CODE not TREE_CODE
3477 to modify a tree code.
3479 Mon Jul 18 11:24:57 1994 Bill Cox (bill@rtl.cygnus.com)
3481 * convert.c (digest_structure_tuple): Fix thinko in TREE_CODE
3484 Mon Jul 18 05:40:15 1994 Doug Evans (dje@canuck.cygnus.com)
3486 * decl.c (warn_bad_function_cast): Define so cc1chill will link.
3488 Thu Jul 14 18:37:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3490 * parse.c (parse_send_action): Do tree_cons *before* checking
3493 Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3495 * convert.c (digest_structure_tuple): Don't use convert to
3496 coerce initial value, use chill_convert_for_assignment instead.
3497 (Thus we also get range_checking.)
3499 * expr.c (build_chill_card): Use force_addr_of instead of
3500 build_chill_addr_expr.
3502 * loop.c (build_temporary_variable): Stylistic tweak.
3503 * loop.c (maybe_make_for_temp): Initialize temp using
3504 explicitly, not using assignment. Avoids a problem if
3505 the expression is read-only.
3506 * typeck.c (smash_dummy_type): Always used the saved TYPE_NAME
3507 and CH_NOVELTY_FLAG.
3509 Wed Jul 6 20:12:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3511 * expr.c, ch-tree.h (finish_chill_unary_op): New function,
3512 based on code ripped out of build_chill_unary_op.
3513 (build_chill_unary_op): Call finish_chill_unary_op unless pass==1.
3514 * satisfy.c (satisfy): Call finish_chill_unary_op when needed.
3516 Mon Jun 27 11:29:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3518 * tree.c (save_if_needed), ch-tree.h: New function.
3519 * typeck.c (build_chill_slice_with_range,
3520 build_chill_slice_with_length): Call save_if_neeed on array arg.
3521 * expr.c (varying_to_slice): Re-write to use save_if_needed.
3523 * typeck.c (extract_constant_from_buffer): Handle BOOLEAN_TYPE.
3525 Mon Jun 27 01:11:10 1994 Wilfried Moser (moser@rtl.cygnus.com)
3527 * inout.c (build_chill_io_list_type): Change layout of __tmp_WIO_list
3528 that it is always the same, regardless if compiled with -fpack
3531 Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3533 * lex.l (yywrap): Kludge to work around mis-synchronization
3534 between lexer (which read ahead) and parser: Don't emit
3535 (left-over) uze_seizefile directives at the end of file.
3537 * typeck.c (build_chill_array_ref): Allow the derived
3538 array indexing syntax for arrays of bit strings.
3539 Add a comment explaining why.
3541 * typeck.c, ch-tree.h (string_assignment_condition): Change
3542 the interface. Return a boolean expression (which can be
3543 used in a conditional at run-time); never expand anything.
3545 * actions.c (chill_convert_for_assignment): Check
3546 string_assignment_condition here, rather than in callers.
3547 * actions.c (chill_expand_assignment): Don't need to check
3548 string_assignment_condition here.
3549 * expr.c (build_chill_function_call): Likewise.
3550 * satisfy.c (safe_satisfy_decl): Update accordingly.
3551 * decl.c (do_decl): Simplify testing and conversion by
3552 deferring everything to chill_convert_for_assignment.
3554 * parse.c: Combine the two variables 'ignore_exprs' and
3555 'ignore_actions' into one variable called 'ignoring'.
3556 * ch-tree.h: Add 'extern int ignoring'.
3557 * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
3558 Rename ignore_actions and ignore_exprs to ignoring.
3559 Remove unneeded extern declarations.
3560 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3561 build_chill_arrow_expr, build_generalized_call, build_delay_action,
3562 build_buffer_type, build_event_type): I changed my mind. It is
3563 cleaner to check for 'ignoring' in the parser, rather than here.
3564 * parse.c (parse_action, parse_primval, parse_opt_mode):
3565 Therefore we must check for ignoring here.
3566 * parse.c (parse_loc_declaration): Set ignoring in pass 2
3567 when parsing the mode.
3569 * tasking.c (generate_tasking_code_variable): Do arithmetic
3570 on signal_code etc using unsigned rather than signed shorts.
3572 * grant.c (static char* current_grant_modename): Removed.
3573 * grant.c (decode_decl case CONST_DECL): Remove error message.
3575 * Make-lang.in (CHILL_SRCS): Add $(srcdir)/ch/parse.c.
3576 * Makefile.in: Fix dependencies for parse.o.
3577 Remove some duplicate dependencies for $(TREE_H).
3579 Mon Jun 13 14:25:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3581 * typeck.c (build_chill_cast): Allow a value cast between
3582 non-discrete object of the same size, but with a pedwarn.
3583 * typeck.c (bit_string_assignment_condition,
3584 char_string_assignment_condition): Merge near-duplicate functions
3585 and place the code in string_assignment_condition.
3587 * decl.c (parm_flag, declare_parm_level, in_param_level_p):
3589 * decl.c (start_chill_function, finish_chill_function): Make
3590 parameter level have same nesting level as body, as required by Z200.
3591 * decl.c (switch_to_pass_2): Always exit if an error has been found.
3592 * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
3593 generated from GRANT ALL.
3594 * decl.c (lookup_name_for_seizing): Don't seize from
3595 the nesting level of builtins (predefined objects).
3596 * decl.c (lookup_name_for_seizing): Make more robust on error.
3598 * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
3599 be 'RESULT' (or 'result'). This makes it more accessible from gdb.
3600 Also, use do_decl to declare it, so that debugging symbols are
3601 generated. And, re-arrange so that actions that need to
3602 be done both passes (such as push_levels) use the same code.
3604 * parse.c (get_type_of): If ignore_exprs, don't lookup name.
3605 * parse.c (end_function): Fix poplevel params.
3606 * parse.c (expect): Don't read forwards on an error.
3607 * parse.c (parse_field): Don't define two tag_list locals!
3608 * parse.c (parse_pass_1_2): Better error message.
3610 * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
3611 parse_opt_mode, rather than vice versa. If parse_opt_mode
3612 returns NULL_EXPR, then parse_mode gives an error.
3613 Change parse_opt_mode (and any functions it calls) to only
3614 return NULL_TREE if there is no mode (even on ignore_exprs).
3615 (parse_set_mode, parse_structure_mode, parse_procedure_mode):
3616 Never return NULL_EXPR.
3617 * tasking.c (build_buffer_type, build_event_type): Return
3618 void_type_node instead of NULL_EXPR if ignore_exprs is true.
3620 * parse.c (parse_synonym_definition): Call parse_untyped_expr
3621 only if we have a mode.
3622 * parse.c (parse_send_action): Parse list of untyped_expr's,
3623 rather than a list of (typed) expressions.
3624 * parse.c (parse_primval): Emit error if '[' seen without
3625 preceding mode name. (If this is to be allowed, call
3626 parse_untyped_expr instead.)
3628 * parse.c (parse_array_index): Renamed to ...
3629 (parse_index_mode): ... to match Z200 terminology.
3630 Re-write to resolve some of the nastier ambiguities,
3631 and allow things like ' CHAR(10) : CHAR(20) '.
3633 * parse.c (parse_tuple_element): Change interface to return
3634 reversed list, so don't call nreverse.
3635 * parse.c (parse_tuple): No longer nreverse element list here.
3636 * parse.c (parse_opt_element_list): Do nreverse here instead.
3637 * parse.c (parse_case_label_list): Call nreverse at end.
3639 Fri Jun 10 15:36:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
3641 * typeck.c (chill_similar): Remove bogus "else".
3643 Wed Jun 8 00:01:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
3645 * ch-tree.h (TYPE_ARRAY_MAX_SIZE): New macro (and comment)
3646 to make it clearer that we are using TYPE_MAX_VALUE in a special way.
3647 * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
3648 * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
3649 * convert.c (convert): When converting a fixed string/array
3650 to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
3651 of (the type of) the padding.
3652 * convert.c (convert): If the concatenation is non-constant, use
3653 the low-level 'build' to set the type of the result (which is usually
3654 a fixed-size array) rather than depend on build_chill_binary_op
3655 to figure it out (it's unable to simplify the size to a constant).
3657 Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
3659 * lang.c (lang_decode_option): Let -fspecial_UC imply
3660 -fno-ignore-case without requiring it explicitly.
3661 * lang.c (lang_decode_option): Support (experimentally)
3662 the -fpack and -fno-pack flags.
3664 Thu Jun 2 20:49:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3666 * configure: Add support for --program-prefix and --program-suffix.
3668 Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3670 * convert.c (digest_constructor): Check that initial value
3671 is compatible with element mode before calling convert.
3672 * typeck.c (chill_compatible): A string mode is not compatible
3673 with an untyped constructor.
3674 * decl.c (do_decl): Clean up error messages. Use error_with_decl.
3676 * ch-tree.h: Fix inconsistencies: bool_true_node ->
3677 boolean_true_node, and bool_false_node -> boolean_false_node.
3678 * typeck.c (valid_array_index_): Minor simplification.
3680 Tue May 31 04:33:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3682 * inout.c (build_chill_writetext): Add correct processing
3683 of POWERSET RANGE (setmode).
3685 * lex.l (same_file): Add searching for file(s) in
3688 Fri May 27 14:22:42 1994 Per Bothner (bothner@kalessin.cygnus.com)
3690 * Make-lang.c (CHILL.mostlyclean, CHILL.distdir): Don't list
3691 yacc/bison output files, since the grammer is no longer in yacc.
3692 * config-lang.in (diff_excludes): Likewise.
3694 Thu May 26 16:38:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3696 * gperf, hash.h, lex.l, parse.h: Rename PROCESS_TYPE token
3697 (in some files spelled PROCESS_TYPE_ to avoid clashes
3698 with the PROCESS_TYPE tree_code) to PROCESS_TYPE_TOKEN.
3700 Thu May 26 02:18:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3702 * timing.c (build_cycle_start): Change call to __define_timeout.
3703 * decl.c (init_decl_processing): Change definitions of
3704 __define_timeout and __wait_timeout.
3706 Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
3708 Replace yacc-based parser with a recursive-decent parser.
3709 (This may seem backwards, but Chill [like C++] is not a
3710 language that is remotely LALR(1). Using a R-D parser
3711 allows us to use look-ahead and to back-up to resolve the
3712 difficult ambiguities.)
3714 * parse.c, parse.h: New files, containing new r-d parser.
3715 * Makefile.in: Update accordingly.
3716 * actions.c (chill_convert_for_assignment): Don't return
3717 NULL_EXPR if ignore_exprs is true. It simplifies the parser
3718 if we consistently reserve NULL_EXPR for a missing expression.
3719 * expr.c (build_chill_function_call): Likewise.
3721 * lex.l: Tweaks for new parser.
3722 * lex.l (prepare_paren_colon, paren_paren_colon_level,
3723 paren_level): Ugly hack no longer needed.
3725 * expr.c (build_chill_function_call): Cleanup.
3726 Call chill_convert_for_assignment to convert IN/INOUT
3727 paramaters on both input and output. For LOC parameters,
3728 give error if actual is a non-referable location.
3729 * actions.c (convert_for_assignment): Add new parameter (a
3730 "place" string used in error messages).
3731 * actions.c (adjust_parm_or_field): Removed.
3732 * actions.c (chill_expand_assignment): Take just a single LHS,
3733 and move support for multiple assignments to ...
3734 (expand_assignment_action): ... here. Some cleaning up.
3735 * timing.c (build_cycle_start): Adjust accordingly.
3736 * actions.c (expand_assignment_to_varying_array): Likewise.
3737 * tasking.c (many places): Ditto.
3738 * ch-tree.h: Fix declarations appropriately.
3740 * parse.c (parse_defining_occurrence_list): Return a single
3741 IDENTIFIER_NODE (instead of a singleton list) in the common
3742 case. Minor complication to save a minor amount of space.
3743 * decl.c (do_based_decls): Move guts of code into ...
3744 (do_based_decl): ... this new function.
3745 * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
3746 * decl.c (push_syndecl): Replace by ...
3747 (push_syndecl): ... (which only supports a single name).
3748 (push_modedef): Only handle a single name.
3749 * tasking.c (build_process_header, build_signal_struct_type):
3752 * expr.c (build_generalized_call): Handle string repetition.
3753 * expr.c (build_chill_repetition_op): Change interface.
3754 * grant.c (decode_constant): Allow parameter list to be
3755 a non-TREE_LIST. (Used for string repetition.)
3757 Wed May 25 11:28:48 1994 Per Bothner (bothner@kalessin.cygnus.com)
3759 * lex.l (make_identifier): Replaced by ...
3760 (read_identifier, handle_name): ... new functions.
3761 * lex.l: Parse an identifiers using read_identifier using
3762 read_identifier and handle_name, rather than having [f]lex
3763 do it. (One reason is that lex uses a fixed-size buffer.)
3765 * lex.l (read_directive, skip_directive): New functions.
3766 Use them to parse compiler-directives, instead of rather
3767 ugly and useless use of lexer start conditions.
3769 Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3771 * decl.c (unnamed_module_number): Renamed to ...
3772 (module_number): .. and make non-static.
3773 (push_module): Always increment module_number.
3774 * lex.l (yywrap): Print warning if no modules seen.
3776 * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
3777 decl to current_seizefile_name (which is unreliable).
3778 * grant.c (chill_grant): Set it here instead.
3780 * expr.c (fold_set_expr): Use int_size_in_bytes instead of
3781 TYPE_PRECISION (which is not defined for a SET_TYPE).
3783 Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
3785 Cleanup to remove need for variables in common storage.
3786 * decl.c: Remove unused use of current_obstack.
3787 * actions.c (maybe_chill_check_decl): Remove unused function.
3788 * actions.h, lang.c: Remove uses of doing_chill_thang.
3789 * ch-tree.h (void_list_node): Make extern (rather than common).
3790 * decl.c (void_list_node): Add definition.
3792 Thu May 19 06:54:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
3794 * configure (build): Build canon_host and canon_target
3795 to pass it to all subsequently generated Makefiles (needed
3796 for testsuite/execute in case of cross build).
3798 Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
3800 * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
3801 the input type, which loses with the no-longer-new 2-pass
3802 implementation, since the input "type" could be an IDENTIFIER_NODE.
3803 * grant.c (raw_decode_mode): Rename to decode_mode.
3805 Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3807 * typeck.c (chill_location): Neither a STRING_CST nor a
3808 CONSTRUCTOR is a location.
3809 * typeck.c (chill_root_mode): Convert a function to a
3810 pointer-to-function.
3811 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3812 build_chill_arrow_expr): If ignore_exprs, return operand
3813 rather than NULL_EXPR. This makes it easier for the parser to
3814 distinguish missing expressions.
3815 * expr.c (build_max_min): Convert the lower bound of a
3816 set to a long before calling run-time routine.
3817 * expr.c (build_chill_pred_or_succ): Use discrete_type_p
3818 to check the argument type.
3819 * expr.c (build_chill_arrow_expr): If argument is not a location,
3820 do a predwarn if it is a STRING_CST or has function type.
3822 Tue May 17 06:05:13 1994 Wilfried Moser (moser@rtl.cygnus.com)
3824 * configure (build): Remove building of canon_host and canon_target.
3825 It doesn't work in any case.
3827 Mon May 16 02:10:35 1994 Wilfried Moser (moser@rtl.cygnus.com)
3829 * configure (build): Build canon_host and canon_target
3830 to pass it to all subsequently generated Makefiles (needed
3831 for testsuite/execute in case of cross build).
3832 * Make-lang.in (chill-runtime): Change chill to CHILL in the case
3833 statement to build chill-runtime automatically.
3835 Mon May 9 15:30:08 1994 Doug Evans (dje@canuck.cygnus.com)
3837 * Makefile.in (FLAGS_TO_PASS): Define.
3839 (../cc1chill): Depend on $(OBJDEPS) $(C_OBJS).
3840 * Make-lang.in (cc1chill): Delete dependency on $(OBJS) $(BC_OBJS).
3841 (CHILL.mostlyclean): Use `mostlyclean' as recursive target.
3843 Sun May 8 13:05:00 1994 Per Bothner (bothner@cygnus.com)
3845 * Make-lang.in (cc1chill): Should not depend on libgcc.a.
3847 Thu May 5 18:58:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
3849 * decl.c (copy_lang_decl): New (dummy) function.
3851 Mon May 2 14:33:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
3853 * parse.y (sendaction): Fix thinko (in sense of condition).
3854 * tasking.c (build_receive_case_label): Another thinko.
3856 * parse.y (optsigdest): Force ignore_exprs to 0 while parsing
3859 * decl.c (build_chill_function_type): Don't call layout_type
3860 (since that may prevent parameter or result types being
3861 properly satisfied).
3862 * satisfy.c (satisfy): Layout FUNCTION_TYPEs.
3863 * parse.y (procmode): Call build_chill_pointer_type, rather
3864 than build_pointer_type (which incorrectly sets TYPE_SIZE).
3866 * parse.y (get_type_of): Handle TYPE_DECL (again).
3867 * parse.y (optresultspec): Call build_chill_reference_type, rather
3868 than build_reference_type (which incorrectly sets TYPE_SIZE).
3869 * parse.y (range_or_mode): Rename to plain range, since it
3870 no longer matches modename.
3871 * actions.c (chill_handle_case_label_range): New function, with
3872 functionality moved out of chill_handle_case_label.
3873 * actions.c (chill_handle_case_label): Handle here the case that
3874 the label_value is a TYPE_DECL (modename). Also clean up some.
3875 * typeck.c (build_chill_slice_with_length): Convert max_index
3876 to the type of min_value. (Old code broke on varying strings.)
3878 Sun May 1 13:53:36 1994 Doug Evans (dje@canuck.cygnus.com)
3880 * Makefile.in (BC_OBJS): Delete all references
3881 (OBJS): Cat ../stamp-objlist to get language independent files.
3882 (../cc1chill): Delete dependency on $(OBJS).
3883 * Make-lang.in (cc1chill): Depend on stamp-objlist.
3885 Sat Apr 30 14:50:15 1994 Per Bothner (bothner@kalessin.cygnus.com)
3887 * lex.h, lex.c: Remove lastiddecl.
3888 * lex.l (name_type_signal): Simplify. We no longer check for
3889 TYPENAME or SIGNALNAME (which was unreliable with two passes).
3890 Also rename to make_identifier.
3891 * parse.y: Cleaned up grammar to not need SIGNALNAME or TYPENAME.
3892 * Makefile.in (stamp-parse); One conflict fewer!

4346 * typeck.c (layout_chill_range_type): Instead of tree_int_cst_lt
4347 use compare_int_csts (which is more robust when signedness differs).
4348 Also, convert the bounds *after* doing range checking.
4350 * ch-tree.def (SET_IN_EXPR): New.
4351 * expr.c (chill_expand_expr): Code to expand SET_IN_EXPR,
4352 moved from expand_expr in ../expr.c. Also add some extra
4353 conversions (because we're now using build_chill_function-call).
4354 * actions.c, decl.c, expr.c, grant.c, parse.y, typeck.c:
4355 Use SET_IN_EXPR in place of IN_EXPR.
4357 * expr.c (build_compare_discrete_expr), ch-tree.h: New function,
4358 with code moved from build_compare_expr.
4359 * expr.c (build_compare_expr): Re-enable compatibility test.

4368 Sun Mar 20 21:49:59 1994 Bill Cox (bill@rtl.cygnus.com)
4370 * actions.c (check_range): Call build_compare_expr rather than
4372 (adjust_parm_or_field): Call convert_for_assignment rathern than
4373 convert, to get the range-checking.
4374 * expr.c (build_chill_pred_or_succ): Fix up rangefail code.
4375 Generate a compile-time message if possible.
4376 (build_compare_expr): Comment out compatibility test - should
4377 not be needed in here. Fix a couple of typos. Add some types
4378 to some build calls.
4380 Sun Mar 20 11:48:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
4382 * decl.c (init_decl_processing): Clean up parameter type
4383 list for __setbitpowerset,
4385 * typeck.c (chill_compatible_classes): Allow the M-reference
4386 to be compatible with the N-value class, with suitable M and N.
4387 * typeck.c (build_chill_slice): Don't smash a void TREE_TYPE.
4388 (We don't need to, and it causes confusion.)
4390 * expr.c (build_compare_expr): Fix thinko. Add save_exprs.
4392 * expr.c (build_compare_expr): Fix a transcription bug
4393 (for converting NULL INSTANCEs). Also #include convert.h.
4395 * expr.c (compare_int_csts): New. Compare INTEGER_CSTs.
4396 Works even if their types have different TREE_UNSIGNED.
4397 * expr.c (finish_chill_binary_op): Moved code dealing with
4398 the comparison operators from here ...
4399 * expr.c (build_compare_expr): ... to new function here.
4400 Also, for discrete types, tries to Do The Right Thing, even for
4401 differing values of TYPE_PRECISION and TREE_UNSIGNED.
4403 * ch-tree.h: Declare new functions.
4404 * typeck.c (valid_array_index_p): Various cleanups,
4405 including using new build_parse_expr.
4406 * parse.y: Use new build_compare_expr.
4408 * inout.c (build_chill_writetext): Handle REFERENCE_TYPE args.
4410 Sun Mar 20 08:54:27 1994 Bill Cox (bill@rtl.cygnus.com)

4422 to get runtime index checking.
4423 * expr.c (build_chill_pred_or_succ): Fix cond tree
4424 to have consistent operand types.
4425 * typeck.c (valid_array_index_p): Change interface to pass
4426 validity conditions back on caller's TREE_LIST. We
4427 cannot link the conditions to anything which a
4428 layout_type routine will expand, since that will occur
4429 before the exception handler is set up.
4430 Change calls to valid_array_index_p also.
4432 Fri Mar 18 14:40:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
4434 * actions.c, except.c, loop.c, tasking.c: Call
4435 build_chill_function_call instead of the C-specific
4436 build_function_call.
4437 * except.c (initialize_exceptions): Fix parmtype of __builtin_setjmp.
4438 * loop.c (top_loop_end_check): Coerce library function arg.
4439 * convert.c, expr.c: Re-write to avoid calls to C-specific
4440 function build_unary_op (e.g. by calling build1 directly).
4442 * typeck.c (chill_equivalent): Change to force failure
4443 for non-matching integral types (even if not ranges).
4445 * typeck.c, ch-tree.h (build_chill_slice): Make non-static.
4446 * expr.c (varying_to_slice): Call build_chill_slice (and not
4447 build_chill_slice_with_length, which does bunches of range
4448 checking and does not allow the length to be zero).
4449 * convert.c (convert): Fix off-by-one error.
4450 * actions.c (chill_expand_array_assignment): Minor cleaning up.
4452 Fri Mar 18 00:12:48 1994 Per Bothner (bothner@deneb.cygnus.com)
4454 * decl.c (init_decl_processing): __lepowerset and __ltpowerset
4455 take *two* pointer parameters, not one.
4456 * satisfy.c (satisfy): Only call the appropriate layout routine
4457 if TYPE_SIZE is 0 (i.e. type hasn't already been laid out).
4458 * typeck.c (build_chill_slice_with_length): Fix Bill's previous fix.
4460 Thu Mar 17 17:29:43 1994 Bill Cox (bill@rtl.cygnus.com)
4462 * expr.c (build_chill_function_call): Give function call the correct
4464 * typeck.c (build_chill_slice_with_length): Restore dynamic range
4465 checking, so it doesn't obscure the CONSTANTness of the length.
4467 Wed Mar 16 17:23:31 1994 Per Bothner (bothner@kalessin.cygnus.com)
4469 * typeck.c (build_chill_slice), expr.c (chill_expand_expr
4470 [case CONCAT_EXPR]): Remove kludge setting slice size upper bound
4471 in TYPE_LANG_SPECIFIC, and restore kludge setting it in MAX_VALUE.
4472 * typeck.c (build_chill_slice): Use TYPE_MAX_VALUE of
4473 array_type if needed for size upper bound of slice_type.
4474 * expr.c (build_concat_expr): Improve calculation of size upper bound.
4476 * typeck.c (valid_array_index_p): Check compatibility using
4478 * typeck.c (build_chill_slice_with_length); For now revert
4479 calling valid_array_index_p on length. (It makes it harder
4480 to realize when the slice is constant length.)
4481 * expr.c (build_chill_indirect_expr): Minor tweak. (This
4482 seems to work around a weird C compiler bug. ??)
4484 * expr.c (build_chill_function_call): Cleanup so it doesn't
4485 call build_function_call (in c-typeck.c).
4486 * typeck.c, expr.c: Use build_chill_function_call instead of
4487 build_function_call (in c-typeck.c).
4489 * parse.y (discrete_mode): Move some of the rules from
4490 non_array_mode into new non-terminal.
4491 (arrayindex): Use discrete_mode (with NAME and TYPENAME) to
4492 avoid some misparses.
4493 * ch-tree.h (SLICE_PTR, SLICE_LENGTH): Removed; unused.
4494 * convert.c (digest_structure_tuple): Add missing parameter.
4495 * decl.c (comptypes): Remove unused prototype.
4496 * decl.c (build_chill_function_type): Handle NULL return_type
4497 correctly (convert to void_type_node).
4498 * decl.c (init_decl_processing): layout boolean_type_node *after*
4499 we've set it's TYPE_MIN_VALUE and TYPE_MAX_VALUE.
4501 Wed Mar 16 16:08:22 1994 Bill Cox (bill@rtl.cygnus.com)

4504 * convert.c (convert): Correct calculation of padding length.
4505 * decl.c (grok_chill_fixedfields): Move ignore_exprs test to
4506 parse.y where it belongs. This permits the removal of a kludge
4507 in make_process_struct.
4508 * lex.l, parse.y: Call to_global_level for several errors. Add
4509 code to output error in only one pass.
4510 * tasking.c (make_process_struct): Delete kludge inserted on

4517 (build_rts_call): Ifdef it out - never used.
4518 (expand_varying_length_assignment): call valid_array_index_p.
4519 rather than validate_varying_array_ref.
4520 * ch-tree.h: Fix prototype for valid_array_index_p.
4521 * expr.c (chill_expand_expr): Call build_chill_array_ref to get
4523 (build_hill_lower, build_chill_upper): Return value now inherits
4524 the novelty of the input parameter.
4525 (varying_to_slice): Use CH_NOVELTY macro rather than calling
4526 chill_novelty directly.
4527 * grant.c (newstring): Make len unsigned and cast xmalloc parameter
4529 (print_integer_type): Pass string value as APPEND's second parameter.
4530 (decode_decl): Pass a boolean expression as print_proc_tail's
4532 (chill_finish_module_code): Make xmalloc's parameter unsigned.
4533 * lex.l: Pass sizes to xmalloc as unsigned ints. Pass second
4534 parameter to in_word_set as unsigned.
4535 * loop.c (build_loop_start): Check top_loop_end_check return value.
4536 * parse.y: Add casts to int for third do_decls parameter, fifth
4537 build_loop_iterator parameter, etc.
4538 * tasking.c (build_receive_case_end): Chack cond_stack before popping.
4539 * typeck.c (validate_varying_array_ref, chill_max_vary_array_index,
4540 valid_array_index): Delete them. They're now unused.
4541 (valid_array_index_p): Add function, call it everywhere that an
4542 array index is checked.
4543 (build_chill_slice): Restore old functionality where varying_to_slice
4544 is called to handle slices of varying arrays, rather than handling
4546 (build_chill_slice_with_range, build_chill_slice_with_length):
4547 Check range limits for TREE_CONST before calling tree_int_cst_lt.
4548 Delete now-obsolete checks of constant indices.
4550 Mon Mar 14 17:26:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4552 * parse.y (modeless_expr): New rule to allow ([...]) and (if...)
4553 to count as untyped_exprs. (This is not really permitted by the
4554 Blue Book, but has been requested by customers.)
4556 Thu Mar 10 10:11:02 1994 Bill Cox (bill@rtl.cygnus.com)
4558 * chill.texi: Document new command-line options.
4559 * expr.c (build_chill_num): Set unsigned parameter for

4561 * lang.c (lang_decode_option): Add command-line options to
4562 enable/disable runtime range-checking.
4563 * lex.l: Eat more whitespace.
4565 Thu Mar 10 09:41:37 1994 Bill Cox (bill@rtl.cygnus.com)
4567 * Makefile.in: Have rules to make parse.h, y.tab.c and other
4568 derived files. This allows the gcc/configure list of CHILL
4569 files machinery to work.
4570 * ch-tree.h (permanent_allocation): Add a parameter flag.
4571 * decl.c (finish_chill_function, finish_decl): Provide the
4572 new permanent_allocation flag.
4573 (poplevel): Return early, avoid a seg fault.
4574 * lex.l (NORMAL): Replace this whole state with the predefined
4575 INITIAL state. Force compilation state to global level after
4576 compiler directive error - prevents endless loop on error.
4577 (handle_use_seizefile_directive): Rewrite for readability.
4578 (chill_same_grant_file): Reindent.
4579 Generally handle whitespace differently.
4580 * regression.prpt: Print ten PR numbers per line. The report's
4583 Wed Mar 9 09:58:51 1994 Bill Cox (bill@rtl.cygnus.com)
4585 * decl.c (do_decl): Suppress the string-assignment-condition
4586 error - it was too often seen.
4587 * expr.c (expand_chill_expr): In CONCAT_EXPR, when argument has a
4588 runtime-changing length (as in a slice), get the parent array's
4589 allocation size from its type tree.
4590 * typeck.c (build_chill_slice): Support VARYING arrays. Pass
4591 parent array's static allocation size along in the slice type.
4593 Wed Mar 9 08:54:24 1994 Bill Cox (bill@rtl.cygnus.com)
4595 * lex.l (name_type_signal): Avoid dereferencing a NULL TRE_TYPE.

4599 * expr.c (build_chill_sizeof): Fix typo in error msg, add
4601 * lex.l (name_type_signal): Add debug output.
4602 * parse.y (call): Allow EVENTNAME and BUFFERNAME parameters
4603 to a call, so that SIZE () works on them.
4604 * tasking.c (make_process_struct): Force ignore_exprs non-zero
4605 when processing a SEIZEd PROCESS declaration. This prevents
4606 grox-fixed_fields from returning a NULL, and indirectly protects
4607 the chill_integer_type_node tree from corruption.
4609 Mon Mar 7 19:14:05 1994 Bill Cox (bill@rtl.cygnus.com)
4611 * Makefile.in: Use the 'all' target to build the runtime
4612 library and chillrt0.o.

4615 chill.regress.cron: Move to utils subdirectory.
4616 * expr.c (build_chill_function_call): Mark the INOUT
4617 temporary so it doesn't get optimized into a
4618 register. Fixes the execute/inout.ch bug.
4619 * typeck.c (layout_chill_range_type): Restrict it
4620 from complaining about an empty string type's
4623 Mon Mar 7 09:06:39 1994 Bill Cox (bill@rtl.cygnus.com)

4627 Add $(FLAGS_TO_PASS) to sub-make invocations.
4628 * ch_decomment.l, ch_makedepend, chill.patches, printf.c,

4655 * inout.c (build_chill_writetext): Add handling of a REAL.
4656 * lex.l (INITIAL): Remove all code to discard 'header lines'.
4658 * parse.y (optheader): Remove - it's obsolete, as is the
4659 HEADEREL token definition.
4661 Fri Mar 4 09:41:18 1994 Bill Cox (bill@rtl.cygnus.com)
4663 * addtest: Fix suffix removal when suffix is .c186.
4664 * regression.sh: Allow for underscores on PR filenames.
4665 * typeck.c: Check in the rewrite mentioned earlier.

4683 range-checking code. Handle reference_type in convert call.
4684 (chill_expand_assignment): Produce an INDIRECT_REF for a

4752 string_assignment_condition for some of it.

4758 name for correctness.
4760 Wed Feb 23 15:07:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4762 New cleaner solution to the following problem:
4763 Chill allows an action to be followed by an ON-handler.
4764 But we don't know if an action has a handler until we've parsed
4765 its end, yet we want to generate extra code to set up an
4766 exception handling contour only if needed. The old solution
4767 would generate code for the action into an rtl sequence, and then
4768 splice in the exception-setup code if we later found we needed it.
4769 This has a few problems (for example it confuses the management
4770 of stack temporaries), and is ugly. Now that the compiler is 2-pass
4771 we have a cleaner solution: In pass 1, we remember which actions
4772 were followed by ON-handlers. In pass 2, we use this information
4773 to generate appropriate code before an action.
4774 * except.c (push_handler, pop_handler): In pass 1, set up data
4775 structures (global_handler_list) to remember if an action has an
4776 ON-handler. In pass 2, digest this information, and setup
4778 * except.c, actions.h (pop_handler): Take an extra int arg.
4779 * except.c (emit_setup_handler): New function, with code (moved
4780 from chill_start_on) to emit code before an action that has a handler.
4781 * except.c (except_init_pass_2): New function.
4782 * parse.y (pass1_2): Call except_init_pass_2 before pass 2.
4783 * parse.y (POP_UNUSED_ON_CONTEXT): Don't call pop_sequence.
4784 * parse.y: Invoke POP_UNUSED_ON_CONTEXT and POP_USED_ON_CONTEXT
4785 in pass 1 as well as pass 2.
4786 * parse.y (BEGIN ... END): Re-arrange logic to avoid block_stack
4787 (local to ../stmt.c) getting out of sync.
4788 * actions.c (push_action): Don't need to emit a NOP,
4789 now that we're no longer moving sequences around.
4790 * actions.c (push_action): Call push_handler even in pass one.
4792 Wed Feb 23 11:06:14 1994 Bill Cox (bill@rtl.cygnus.com)

5407 * c-typeck.c (really_start_incremental_init): Save
5408 constructor_elements and (old value of) constructor_stack
5409 on constructor_stack, to allow for nested initializers.
5410 * ch-convert.c (digest_constructor): If we need a varying
5411 array, and have a constructor (for the array elements),
5412 make sure to use convert so that the constructor gets
5413 wrapped in an implicit record constructor.
5414 * ch-decl.c (do_decl): If there is no initializer for a
5415 varying array (or bitstring), create default constructor.
5417 * ch-expr.c (build_chill_lower): Fix thinko for ARRAY_TYPE.

5419 original decl to check if we need to make an rtl.
5421 * ch-typeck.c (build_chill_array_ref_1), ch-tree.h: New function
5422 which does the actual work for build_chill_array_ref (which
5423 now just loops over an argument list).
5424 * ch-actions.c, ch-expr.c, ch-inout.c: Use build_chill_array_ref_1
5425 instead of build_chill_array_ref where appropriate.
5426 * ch-actions.c, ch-expr.c, ch-typeck.c: Make operand 1 of a
5427 VARY_ARRAY_REF is a single index, not an index list.
5429 * ch-grant.c (__init_list): Renamed to _ch_init_list, to
5430 avoid a conflict on the Alpha.

5442 * ch-expr.c (build_chill_addr_expr): Add error message.
5443 * ch-grant.c (chill_finish_module_code): Avoid abort by
5444 giving the init_list constructor a type.
5445 (chill_finish_compile): Delete unused code.
5446 * ch-lex.l: Make most build_init_2 calls from the

5454 'struct ch_class class = chill_expr_class (expr);' to
5455 'struct ch_class class; class = chill_expr_class (expr);'
5456 to work around a bug in /usr/ucb/cc on SunOS4.
5458 Mon Jan 10 18:29:36 1994 Bill Cox (bill@rtl.cygnus.com)
5460 * ch-actions.c (chill_convert_for_assignment): Avoid seg fault.

5485 (convert): Use convert1 where appropriate.
5486 * ch-typeck.c: Formatting change.
5487 * ch-parse.y (build_chill_constructor): Fix thinko.
5489 * ch-expr.c (varying_to_slice): If array is not referable,
5490 call save_expr on it, rather than stabilize_reference.
5491 * ch-satisfy.c (safe_satify_decl, for CONST_DECL):
5492 Don't force value to value class if mode is not explicitly
5493 specified. Also, make sure convert etc is only done once.
5495 Sat Jan 8 16:37:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
5497 * ch-decl.c (build_chill_function_type): Don't call
5498 build_function_type, because it does hash canonicalization,
5499 which once in a while looses badly.
5500 * tree.c (build_function_type): Remove no-longer-needed test
5501 for doing_chill_thang.
5503 * ch-tree.h (CH_DERIVED_FLAG): New flag.

5517 convert_float, convert_number): Set CH_DERIVED_FLAG for literals.
5518 * ch-expr.c (finish_chill_binary_op): Use convert_to_class.
5519 * ch-satisfy.c (safe_satisfy_decl): For CONST_DECL, make sure
5520 DECL_INITIAL gets set to result of convert.
5521 Also, clear CH_DERIVED_FLAG for SYN value.
5522 * expr.c (store_constructor): If a [power]set is exactly one
5523 word long, use single-word move.
5525 Sat Jan 8 08:38:29 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5527 * c-typeck.c (chill_initializer_constant_valid_p): Fix typo.
5529 Wed Jan 5 05:18:46 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5531 * ch-typeck.c (build_chill_slice_with_length): Test that ARRAY is of
5532 ARRAY_TYPE before assuming so. Also, subtract 1 from LENGTH in
5533 computation of SLICE_END.
5535 * ch-typeck.c (chill_location): Treat CONSTRUCTORs like STRING_CSTs.
5537 * ch-expr.c (build_chill_indirect_ref): Handle MODE == NULL_TREE.
5539 * ch-expr.c (fold_set_expr): Handle OP1 == NULL_TREE (which happens
5540 for unary set operations).
5542 * ch-expr.c (build_chill_array_expr): Take new argument FORCE. All
5543 callers changed. All callers changed.
5545 * ch-convert.c (digest_structure_tuple): Handle SELECTED_VARIANT
5546 being NULL_TREE until we've started walking the list of values via
5547 the loop over VARIANTs.
5549 * ch-parse.y (build_chill_constructor): If we see an IDENTIFIER_NODE,
5550 treat it as an enum value (and hence constant). Also, only set
5551 TREE_STATIC if the constructor is indeed constant.
5552 * c-typeck.c (chill_initializer_constant_valid_p): If we see a
5553 VAR_DECL, test the TREE_CONSTANT field of the DECL_INITIAL, don't
5554 recurse on the DECL_INITIAL.
5556 Wed Jan 5 01:24:50 1994 Bill Cox (bill@cygnus.com)
5558 * Makefile.in: Add CHILL to LANGUAGES variable.
5559 * ch-actions.c (check_range): Call build_binary_op instead of
5560 fold, build to get the common types chosen.
5561 (cond_range_exception, cond_overflow_exception,
5562 cond_type_range_exception): Delete, obsolete.
5563 (chill_convert_for_assignment): Enable this, get particular
5564 about when to generate rangecheck code.
5565 * ch-expr.c (build_chill_function_call): Sketch in where to
5566 perform chill_convert_for_assignment on actual parameters.
5567 (build_chill_addr_expr): Correct compiler warning.
5568 * ch-loop.c (build_chill_iterator): Add runtime check for
5569 negative loop step expression.
5570 * ch-tree.h: Add prototype.
5571 * ch-typeck.c (chill_max_vary_array_ref): Correct misunderstanding.
5572 A varying array's length field counts the NUMBER of active array
5573 array entries, not the byte-length of them.
5575 Tue Jan 4 17:57:39 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5577 * ch-decl.c (do_decl): Call `suspend_momenary' if the
5578 converted constructor must live on the permanent_obstack.
5579 * ch-convert.c (convert): When building a new SET_TYPE
5580 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5581 * c-typeck.c (chill_initializer_constant_valid_p): Handle VAR_DECLs.
5583 * ch-typeck.c (chill_location): CONSTRUCTORS that are static

5586 on permanent_obstack if necessary.
5588 * ch-convert.c (digest_structure_tuple): When building a new SET_TYPE

5592 the patch below helped to mess up.
5594 * ch-expr.c (build_chill_arrow_expr): Call `mark_addressable'.
5595 (build_chill_addr_expr): Take new argument ERRORMSG.
5596 All callers changed. Also, call `build_chill_addr_expr' where
5597 we used to call `build1 (ADDR_EXPR, ptr_type_node, ...)' since
5598 that now calls `mark_addressable' automagically.
5600 * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.
5601 This is needed because variables may appear in initialization
5602 statements, and their DECL_INITIALs are their values at
5603 initialization time.
5604 * ch-convert.c (digest_structure_tuple,digest_constructor): Changed
5605 to handle VAR_DECLs as initializers.
5607 * ch-convert.c (digest_structure_tuple): Copy elements of INITS so
5608 they aren't destroyed for later use.

5613 parameter for varying_array_ref calculations.
5614 (build_chill_indirect_ref): Prevent seg fault due to syntax error.
5615 * ch-typeck.c (build_chill_slice_with_range): Correct issuance
5616 of bogus error in votrics.
5617 (build_chill_slice_with_length): Change for debug tracability.
5619 Tue Jan 4 02:43:37 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5621 * ch-convert.c (digest_structure_tuple): Fix phasing problem in
5622 handling variant record initializers.
5623 (various places): Change `pop_init_level' calls to match
5624 `push_init_level' wrt implicit variable.
5626 * ch-typeck.c (build_chill_slice): Convert the dynamic max index to
5627 `integer_type_node' before using it in comparisons. FIXME: should
5628 this be done in `chill_max_vary_array_index' by default?
5630 Tue Jan 4 00:24:14 1994 Bill Cox (bill@cygnus.com)
5632 * ch-actions.c: Fix comments.
5633 * ch-parse.y: Define caseaction_flag.
5634 (caseaction): Create new caseaction_flag node at the start,
5635 then free it at the end. Check it before the ELSE code.
5636 (expanded_case_label): Check the flag here. If set in either
5637 place, generate a jump to the end of the case.
5638 * ch-typeck.c (build_chill_slice_with_length,
5639 build_chill_slice_with_range): Add lots of compile-time
5640 parameter range checking.
5642 Mon Jan 3 21:49:04 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5644 * ch-convert.c (digest_structure_tuple): Call `push_init_level' with
5645 implicit==0 everywhere, not 1.
5646 (digest_constructor): Ditto.
5648 * ch-actions.c (check_range): Permit limits to be NULL_TREE.
5649 Also, hack out some dead code.
5650 * ch-typeck.c (build_chill_slice): Check varying and non-varying
5651 slice constructs for range failures.
5652 (build_chill_slice_with_range): Reindented, but not changed.
5654 * ch-typeck.c (chill_max_vary_array_index): New function.
5655 * ch-expr.c (chill_expand_expr): Call it.
5657 * ch-decl.c (var_data_id, var_length_id): New variables.
5658 (init_decl_processing): Initialize them. All calls to
5659 get_identifier (VAR_LENGTH or VAR_DATA) are now replaced
5660 by references to these variables. This simplifies the code
5661 w/o obscuring anything.
5663 Mon Jan 3 21:24:44 1994 Bill Cox (bill@cygnus.com)
5665 * c-typeck.c: Fix comment.
5666 * ch-actions.c (chill_expand_assignment): Error assigning to
5667 READONLY location. (PR_3903) Pass filename, linenumber
5668 to setbitpowerset runtime routine.
5669 * ch-decl.c (init_decl_processing): Add filename, linenumber
5670 parameters to setbitpowerset prototype.
5671 * ch-expr.c (build_chill_function_call): Error when passing a
5672 READonly location as a LOC or INOUT parameter.
5673 * ch-parse.y (mode): Correct code marking type as readonly.
5675 Mon Jan 3 19:03:55 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5677 * ch-actions.c (chill_expand_assignment): Disable code that defeats
5678 building varying array references.
5679 * ch-expr.c (chill_expand_expr): Add rangecheck code to
5680 VARY_ARRAY_REF case.
5681 * ch-typeck.c (build_chill_array_ref): Don't call an `expand_'
5682 function (in this case, `validate_varying_array_ref') when we're
5683 doing a `build_' operation.
5685 * ch-typeck.c (validate_varying_array_ref): Simplify interface
5686 since INDEX parameter can never meaningfully be an INDEXLIST.
5687 * ch-actions.c (expand_varying_length_assignment): Caller changed.
5689 Mon Jan 3 07:29:45 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5691 * ch-typeck.c (build_chill_cast): Set TREE_CONSTANT on NOP_EXPRs.
5692 * ch-convert.c (digest_structure_tuple): Switch to permanent_obstack
5693 if we need to build a CONSTRUCTOR for a SET_TYPE initializer.
5694 (digest_structure_tuple): If TREE_VALUE (VALUE) == NULL_TREE, don't
5695 call CH_COMPATIBLE or try to convert it to TREE_TYPE (FIELD). This
5696 can happen when constructors are output incrementally.
5697 * c-typeck.c (initializer_constant_valid_p): Handle SET_TYPEs.
5698 * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
5701 Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5703 * ch-convert (digest_structure_tuple): Handle SET_TYPEs. Also, call
5704 `convert' so we can handle INSTANCE types (and other anomolies)
5707 * ch-convert.c (digest_structure_tuple): Fixed variant
5708 structure initialization. Also fixed a typo (TYPE_NAME
5709 was being used on a FIELD_DECL instead of DECL_NAME).
5710 * c-typeck.c (initializer_constant_valid_p): Pass missing
5711 ENDTYPE argument on recursive call.
5712 (set_init_field): New function, needed by ch-convert.c change above.
5714 * ch-decl.c (layout_chill_variants): Added a FIXME next to an
5715 almost certain typo.
5717 * ch-expr.c (build_chill_arrow_expr): Call `build1' and set
5718 TREE_CONSTANT for static references.
5719 * ch-except.c (chill_start_on): Change calls to
5720 `build_unary_op' (which is C-specific) to `build_chill_arrow_expr'
5721 which has CHILL semantics.
5722 * ch-convert.c (convert): Ditto (albeit in some disabled code).
5724 Sat Jan 1 21:26:43 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5726 * ch-satisfy.c (safe_satisfy_decl): Reorder conditional test of
5727 TREE_CODE of DECL in case it's altered by actions in the switch.
5729 * ch-satisfy.c (satisfy): Undo abort added earlier on 1 Jan. CVS log
5730 mentions where to find code that triggers this case.
5732 * ch-actions.c (adjust_parm_or_field): Handle CONSTRUCTORS here as
5735 * ch-convert.c (digest_structure_tuple): Push to permanent_obstack if
5736 we're dealing with a CONSTRUCTOR that is TREE_PERMANENT.
5737 (digest_constructor): Ditto.
5739 Sat Jan 1 10:29:19 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5741 * ch-parse.y (handleraction,resultaction,assignaction,call): Modified
5742 so that CONSTRUCTORS are properly handled before being used.
5744 * ch-convert.c (chill_start_init): New function. All callers to
5745 `start_init' changed to call this function instead.
5746 (digest_struct_tuple): Defend against initialization machinery
5747 mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
5748 IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
5749 needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
5750 can be refered to throughout the compilation unit. Also remove an
5751 extraneous call to `process_init_element' erroneously added to the
5752 variant record sub-loop.
5753 (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
5754 CONSTRUCTORS of SET_TYPE.
5755 * ch-parse.y (build_chill_constructor): Refix typo. Also set
5756 TREE_STATIC if at top level.
5758 * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
5759 TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
5760 should have been called.
5762 * ch-convert.c (digest_struct_tuple): Restore code which tracks
5763 field initializations so that the compiler can deduce what variant
5764 initializations to assume.
5766 * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
5767 when we push into a scope that has a DECL with a CONSTRUCTOR as its
5770 * ch-parse.y (build_chill_constructor): Change the name of the

5775 constant ADDR_EXPRs.
5776 (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT
5777 on JBUF_REF (instead of calling `build1' which does not).
5779 * ch-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
5781 * ch-typeck.c (chill_expand_tuple): Deleted.
5782 * ch-parse.y (primval rule): Don't call `chill_expand_tuple';
5783 instead, use initialization machinery for CONSTRUCTORS that
5785 * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
5786 that are created here.
5787 * ch-satisfy (satisfy): Abort in case we would have called
5788 chill_expand_tuple. FIXME: some other code is needed here,
5789 but I don't know what yet.
5791 * ch-parse.y (build_chill_constructor): New function to
5792 propagate TREE_CONSTANT bits to CONSTRUCTORS.

5810 * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
5811 rewritten to work with GCC's initialization code. The basic change
5812 was to keep the initializers in sync with the initialization
5813 machinery that `process_init_element' imposes. Both of these
5814 functions now return `void'.
5815 * ch-convert.c (convert): Changed calls to `digest_...' functions.
5817 FIXME: the code handling UNION_TYPE (and variant records) has not

5829 * ch-parse.y: Cleanup handling of RETURN actions, to distinguish
5830 a RETURN without a value (which cannot have an exception
5831 handler) from a RETURN with a value (which can). Eliminate
5832 some shift/reduce and reduce/reduce conflicts.
5834 Thu Dec 30 17:42:32 1993 Michael Tiemann (tiemann@blues.cygnus.com)
5836 * ch-inout.c (build_chill_writetext): Deal with 2 cases where
5837 types returned from `type_for_size' are not expected. FIXME.
5838 * ch-decl.c (init_decl_processing): Mark `char_type_node' unsigned.
5839 This is required when range checking is enabled.

5843 DELAY CASE works now.
5844 * ch-decl.c (init_decl_processing): Move rest of tasking-related

5888 (locdec): process event decls here, too.
5889 (mode): Add code to forbid READonly EVENT and BUFFER decls. Delete
5890 code which required EVENTs and BUFFERs to be declared at global scope.
5891 (simple_name_string): Add an EVENTNAME.
5892 * ch-satisfy.c (safe_satisfy_decl): Prevent a syntax error from
5893 becoming a seg fault.

5907 * gcc.c (CHILL SPECS): Delete references to -M -MM -MD -MMD
5908 options. Delete C-specific defines. Disable piping from
5909 pre-processor to cc1chill (even if -pipe is specified), since cc1chill
5910 rewinds its input for its second pass. Piping still works
5911 from cc1chill to as.
5913 Thu Dec 23 12:31:55 1993 Bill Cox (bill@rtl.cygnus.com)
5915 * ch-tasking.c (decl_tasking_code_variable): Assure that the

5922 Wed Dec 22 10:46:31 1993 Bill Cox (bill@rtl.cygnus.com)
5924 * ch-decl.c (do_seize): Delete - it's unused. Fix comments.
5925 * ch-loop.c (build_chill_iterator): Convert BY expression
5926 so loop involving a SET works. Additional errors generated
5927 for numbered SET expression as start or end expression.
5928 * ch-tree.h: Prototypes for future DELAY functions.
5929 * ch-typeck.c: Standard indentation.

5951 distinguish a string from a char array, and to distinguish a
5952 bitstring from regulat (power)set. (Needed for Chill.)
5953 * dbxout.c (dbxout_type): Only check for baseclasses in
5954 type.binfo is a vector. (It is used in Chill for tagged unions.)

5976 * ch-tree.h: Fix prototypes.
5977 * ch-typeck.c (smash_dummy_type): Handle all four kinds of LANG_TYPE

5994 * ch-decl.c (push_scope_decls): Re-arrange so that normal
5995 (non-seize) declarations are proclaim_decl'd *before* we
5996 handle the ALIAS_DECLs for seizes. The advantage is
5997 that we can now test for (an approximation) to the
5998 'seizeable' concept, thus avoiding duplicate definitions
5999 when a module has both GRANTs and SEIZE ALL.
6001 * ch-expr.c (build_chill_arrow_expr): No longer re-write
6002 addr-of-conversion to pointer-conversion-of-addr.

6010 * ch-tree.h (chill_root_resulting_mode): Fix typo (missing '_').
6012 * ch-expr.c (finish_chill_binary_op): Use CH_ROOT_RESULTING_MODE
6013 macro (which works on expressions), rather than CH_RESULTING_MODE
6014 (which works on modes, and isn't quite correct).
6015 * ch-tree.h (CH_IS_BOUND_REFERENCE_MODE): New macro.

6017 Use the new macro, which handles NEWMODEs of PTR correctly.

6019 dynamic-length array (and string) types (e.g. slices).
6020 * ch-typeck.c (chill_root_mode): If the mode has a Novelty,
6021 just return it as is. (This is still not 100% correct for
6022 NEWMODE of RANGEs, but is close enough.)

6047 to print buffer size - it's no longer kept here.

6141 of set elements of similar set modes.
6143 * ch-parse.y (caseaction): Call language-independent
6144 expand_start_case rather than c_expand_start_case (which
6145 doesn't allow chars or booleans).

6730 code variables associated with a process or signal.
6731 * ch-tasking.c (build_gen_inst, build_gen_ptype): Use the decl's

6746 static variable, point the process' function_decl at it for later
6747 reference by build_start_process.
6748 (print_mode): Use CHILL upper-case convention to print modes.
6749 * ch-lex.l: Must initialize tasking-related trees to NULL at start
6750 of each pass, or we lose the fact that the user did or did not
6751 specify a value for each of them.
6752 * ch-parse.y (check_end_label, action, exceptlist): Only output
6753 error message in pass 1.
6754 (sendaction): Add comments.

6759 passes, using do_decl so we can pass the pass 2 value of the
6760 process_type or signal_code to it. Only update the process_type

6762 parameter to know whether to include an init expression.
6763 (build_process_header): Attach tasking-code_variable to process
6764 function_decl for easy access later, not through the hash table.

6779 generation for decls to not use DECL_ASSEMBLER_NAME.
6780 * ch-decl.c: Set DECL_ASSEMBLER_NAME to DECL_NAME.
6781 This matches C, and allows dbxout to emit proper user-level names.
6782 (It would be cleaner to fix dbxout to use DECL_NAME ...)

6801 * ch-expr.c (finish_chill_binary_op): Convert TRUNC_DIV_EXPR
6802 to RDIV_EXPR if an operand is floating. (This functionality
6803 got dropped when hacking finish_chill_binary_op).
6805 * ch-actions.c (build_chill_case_expr): Set type to NULL_TREE.
6806 not error_mark_node.
6807 * ch-actions.c (chill_expand_assignment): Allow such borderline
6808 constructs as: LHS OR:= [X].
6809 * ch-convert.c (convert): Hande CASE_EXPR (and COND_EXPR)
6810 with unknown (NULL_EXPR) type, not just CONSTRUCTORS.
6811 * ch-decl.c (do_decl): Remove CONSTRUCTOR kludge.
6812 * ch-typeck.c (chill_compatible): Allow expr to have NULL mode
6813 if it's a CASE_EXPR or COND_EXPR (and not just CONSTRUCTOR).

6827 commented-out code as example for assignment of module address to its
6830 Sun Oct 17 15:16:54 1993 Bill Cox (bill@cygnus.com)
6832 * ch-convert.c: Move semicolon to separate line - easier to see.
6833 * ch-decl.c (do_decl): Handle untyped_expr initializers by
6834 simply using the variable's declared type - no compatibility
6835 check can be made if the expression has no type.
6836 * ch-expr.c (expand_packed_set): Fix endless loop - increment
6838 (fold_set_expr): Fix two other endless loops by passing
6839 correct parameters to unpack_set_constructor.

7073 stabilize_reference on RHS.
7074 * ch-typeck.c (build_chill_modify_expr), ch-tree.h: Remove

7098 push_extern_process and push_extern_signal.
7099 * ch-parse.y (end_function): Delete parameter. Check current_function_decl

7123 * ch-tree.h (CH_LOCATION_P): New macro.
7124 * ch-typeck.c (layout_chill_range_type): Fix call to
7125 type_for_size, when figuring out a defaulted parent type.
7126 * ch-expr.c (build_chill_lower, build_chill_sizeof): Check
7127 for TREE_CODE_CLASS != 't' rather than == 'd'.
7128 * ch-expr.c (build_chill_function_call): Use CH_LOCATION_P
7129 to check for location, rather than TYPE_CODE_CLASS == 'd'.
7131 * ch-tree.c (build_string_type): Make 2-pass safe. Also,
7132 change parameter to be length, not index type.
7133 * ch-parse.y (mode2), ch-expr.c (build_concat_expr), ch-lex.l
7134 (build_chill_string): Modify callers of build_string_type accordingly.
7135 * ch-lex.l (check_newline): Don't look for # directive inside a
7137 * ch-grant.c (grant_array_type): Make more robust for char-
7138 and bit-strings (allow non-constant sizes). Change parameters
7139 and return types. (raw_decode_mode): Use grant_array_type
7140 for bitstrings. (otherwise): Fix grant_array_type callers.
7142 Mon Sep 27 16:57:57 1993 Per Bothner (bothner@kalessin.cygnus.com)
7144 Remove changes of Sep 15.
7145 * ch-tree.h (CH_SINGLETON_DOMAIN): Removed.
7146 * ch-typeck.c (chill_similar): Don't allow a singleton
7147 powerset to be similar to its domain.
7148 * ch-convert.c (convert_to_boolean): Don't convert a singleton
7149 SET_TYPE constructor to a Boolean.
7151 * ch-actions.c (chill_expand_assignment): Handle IN_EXPR on
7152 LHS of assignment, which is what we're current (temporarily?) using.
7154 Mon Sep 27 06:01:57 1993 Bill Cox (bill@rtl.cygnus.com)
7156 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
7157 ch-grant.c, ch-inout.c, ch-parse.y, ch-satisfy.c,
7158 ch-tasking.c, ch-tree.c, ch-tree.h, ch-typeck.c:
7159 -Wall cleanup. Add prototypes where missing.
7160 Delete unused variables. Cast uses of tree_codes
7161 to chill_tree_code, which they are.
7163 Sun Sep 26 13:09:57 1993 Bill Cox (bill@rtl.cygnus.com)
7165 * ch-decl.c (do_decl): Save initializer in pass zero
7167 * ch-lex.l: Fix comments, indentation.
7168 * ch-parse.y: Standardize error messages to use
7169 uppercase for CHILL keywords rather than quoting them.
7170 Suggestion from docs department.
7171 * ch-tasking.c: Pervasive changes to get processes to
7173 * ch-tree.h: Delete prototypes for functions whic
7174 I made static inside ch-tasking.c.

7178 * ch-lex.l (yywrap): Call `check_newline' in case the file
7179 started with a line directive.
7181 Sat Sep 25 13:54:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
7183 * ch-decl.c: Expand pre-amble comment.
7184 * ch-decl.c (struct scope, push_module): Use new field
7185 tail_chain_module to build child-module list in order.
7186 (Just to make compiler debugging a little less confusing.)
7188 * ch-decl.c (struct scope): New field weak_decls.
7189 * ch-decl.c (find_implied_types): New interface. Now pre-pend
7190 new enum types to a given input list. This makes it easier to
7191 avoid duplicates, which should at least be more efficient.
7192 Also, handle FUNCTION_DECL.
7193 * ch-decl.c (bind_saved_names): Removed. Distribute its
7194 functionality over new functions (push_scope_decls, pop_scope_decls,
7195 build_implied_names, bind_sub_modules). The goal (which seems to
7196 have been more-or-less attained) was to fix weak name handling.
7197 * ch-decl.c (poplevel): Use new function pop_scope_decls.
7199 * ch-tasking.c (build_signal_struct, build_tasking_message_type):
7200 Use build_decl directly, rather than grok_chill_fixedfields
7201 (which depends on ignore_exprs and has more overhead).
7202 * ch-tasking.c (build_signal_struct): Construct the type
7204 * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
7205 than build_array_ref (which does C-specific "optimizations").
7206 (Hence move my_build_array_ref up earlier in the file.)
7208 Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7210 * ch-tasking.c: Declare static variable `void_ftype_void'.
7211 (chill_tasking_init): Initialize `void_ftype_void' here.
7212 (build_tasking_struct): Use, don't declare `void_ftype_void'.
7213 (generate_tasking_code_variable): Call `do_decl', not
7214 `decl_temp1' to declare TASKING_CODE_NAME.
7215 (tasking_setup): Drop into 1-pass mode so that all
7216 tasking-related declarations are installed in the global
7217 scope. Use correct CHILL types for initializers (since
7218 ptr_type_node doesn't have the right meaning for CHILL).
7219 Also, call `do_decl' instead of `decl_temp1' for
7221 (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
7222 `chill_finish_compile' in sync between passes.
7224 * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
7225 declarations on pass zero. Keep obstacks in sync, and always
7226 call `finish_decl' for pass zero declarations.
7227 (push_chill_extern_function): Keep obstacks in sync, and always
7228 call `finish_decl' for pass zero declarations.
7229 (build_enumerator): Ditto.
7230 (grok_chill_variantdefs): Change PASS test to exclude only
7232 (finish_struct): Ditto.
7233 * ch-expr.c (build_chill_component_ref): Ditto.
7234 (build_chill_binary_op): Ditto.
7235 * ch-tree.c (build_powerset_type): Ditto.
7236 (build_bitstring_type): Ditto.
7237 * ch-typeck.c (build_chill_range_type): Ditto.
7238 (build_chill_struct_type): Ditto.
7240 * ch-decl.c (build_chill_exception_decl): Clarify reasons for
7241 extra pushing and popping of obstacks.
7243 * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
7244 on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
7246 * ch-grant.c (chill_finish_compile): Clear out both
7247 MODULE_INIT_LIST and TASKING_LIST if either contains stuff
7250 * ch-parse.y (rccase_label): Add NAME rules so that pass one
7251 works w/o knowing we're parsing a signal. Simplify SIGNALNAME
7252 rules since we only get SIGNALNAME tokens in pass two.
7253 (sendaction): Ditto.
7254 * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
7255 BUFFERNAME on pass two. The grammar now handles this.
7256 * ch-decl.c (lookup_remembered_decl): Deleted.
7258 Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
7260 * ch-decl.c (lookup_remembered_names): Removed. It was being
7261 misused in ch-lex.l.
7262 * ch-lex.l (name_type_signal): Revert last change. Basically,
7263 we cannot use the C typedef/variable name trick in CHILL, due
7264 due to the language's 2-pass nature.
7265 * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
7267 * ch-tree.h (lookup_remembered_name): Comment out the prototype.
7269 Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7271 * ch-decl.c (do_decl, push_chill_extern_function): Change pass
7272 checks so the pass == 0 case is handled for built-in types.
7273 (push_modedef): Add check for error_mark_node.
7274 (lookup_remembered_decl): New function.
7275 (pushlevel, poplevel) Change pass checks.
7276 (pushdecl): Check type as well for NULL.
7277 (build_enumerator): Handle pass == 0 case.
7278 * ch-lex.l: Use lookup_remembered_decl to get lastiddecl
7280 * ch-parse.y: Set pass to zero to indicate initial decl processing.
7281 Replace NAME references with SIGNALNAME references.
7282 (startaction): Only check copy number if not ignoring actions.
7283 Always call build_chill_start_process.
7284 (optstartset): Don't lookup the instance name.
7285 * ch-tasking.c (generate_tasking_code_variable): Replace
7286 do_decl call with decl_temp1 call.

7288 (build_tasking_message_type): Layout the type.
7289 (rc_state_type): New structure to keep nested receive-case
7291 (build_chill_receive_case_start, build_chill_receive_case_end):
7295 Fri Sep 24 04:19:15 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7297 * ch-tasking.c (build_chill_receive_case_start): `namedecl'
7298 should be a _DECL, not an IDENTIFIER_NODE.
7300 Thu Sep 23 18:18:24 1993 Per Bothner (bothner@kalessin.cygnus.com)
7302 * ch-decl.c (find_implied_types): Handle VAR_DECLs.

7320 Changes to store in the new DECL_SEIZEFILE field each seize
7321 ALIAS_DECL the name in the most recent use_seize_file directive.
7322 (This requires that use_seize_file directives written to the
7323 grant file be written before the SEIZEs that need it.)
7324 Allow clashing declarations granted into the global scope
7325 (produce a warning), but remember the seizefile case from
7326 (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
7327 The a SEIZE will select the granted decl that matches its
7328 DECL_SEIZEFILE (in other words: grants from the most recent
7329 use_seize_file will be preferred).
7330 * ch-tree.h (DECL_SEIZEFILE), ch-tree.def: New macro.
7331 * ch-tree.h (global_value, IDENTIFIER_GLOBAL_VALUE): Renamed
7332 to outer_value, IDENTIFIER_OUTER_VALUE.

7336 Changed to have type TREE_LIST of pointer to IDENTIFIER_NODE.
7337 * ch-lex.l (handle_use_seizefile_directive): Modify appropriately.
7338 Don't call grant_use_seizefile.
7339 * ch-lex.l (mark_use_seizefile_written): New function.
7340 * ch-grant.c (decode_decl): Write out use_seize_file directive,
7341 if needed, before writing a seize declarations.
7342 * ch-decl.c (pop_module): Handle decls granted into the global
7343 module specially, setting IDENTIFIER_OUTER_VALUE.
7344 * ch-decl.c (lookup_name_for_seizing): Check IDENTIFIER_OUTER_VALUE.
7346 Thu Sep 23 19:05:37 1993 Bill Cox (bill@cygnus.com)
7348 * ch-decl.c (push_chill_extern_process): Delete unused variables,
7349 declare the process' tasking_code variable as external.
7350 * ch-parse.y (process): Force ignore_exprs to FALSE while parsing
7352 * ch-tasking.c (sigdef): Move resetting of quasi_signal from here
7354 * ch-tree.h: Add prototype.

7359 * ch-expr.c (build_chill_function_call): Move possible call to
7360 chill_start_module_code until we know we're not calling a builtin.
7361 * ch-decl.c (save_expr_under_name): Use pushdecllist,
7362 not proclaim_decl (which provide for popping the decl).
7363 * ch-parse.y (optname): Also allow TYPENAME.
7365 Thu Sep 23 09:18:35 1993 Bill Cox (bill@cygnus.com)
7367 * ch-decl.c (print_lang_decl): Make weak name output more standard.

7393 * ch-grant.c (print_struct): Add missing loop for tag_list.
7394 (print_struct): Look for variant fields by checking for a
7395 UNION_TYPE, not a NULL name, since we must use a dummy name.
7396 * ch-parse.y (structured_variable): Various fixing.
7397 * ch-decl.c (shadow_record_fields): Rename arg decl -> struct_val.
7399 * ch-satisfy.c (safe_satisfy_decl): Disable copying of modes
7400 for NEWMODE (and hence novelty checking), until we figure out
7403 * ch-except.c (finish_handler_array): Use null_pointer_node,

7430 Change callers appropriately.
7432 * ch-tree.h (TYPE_TAG_VALUES): Add an extra level of TREE_LIST,

7483 REFERENCE_TYPE still has VALUE class, even if an ADDR_EXPR.
7484 * ch-actions.c (adjust_parm_or_field):, ch-tree.h: Change last
7485 parameter, so we can reliably recognize LOC parameters.
7486 * ch-tasking.c, ch-expr.c: Change callers appropriately.

8531 way I allocated the shadow_list on an obstack was too fragile,

8711 theses in its extern name.
8712 (check_newline): Call getlc less often, so that user
8713 labels aren't lowercased before their time. Add BEGIN

10035 Sat Apr 10 01:10:51 1993 Per Bothner (bothner@rtl.cygnus.com)
10037 * ch-parse,y (in_pseudo_module): New variable. Try if we're

10117 * ch-decl.c (push_parms): Use new massage_param_node().

10164 Fri Apr 2 21:55:14 1993 Per Bothner (bothner@rtl.cygnus.com)
10166 Major re-write of New module/seize/grant stuff.
10167 Now, a grantfile is a spec module and contains all the
10168 top-level declarations of the granting module, not just
10169 those that are granted. It also contains explicit grant
10170 statments naming those declared names that are granted.
10171 It also has seize statements and use_seize_file directives
10172 to correctly handle transitive dependencies.
10174 * ch-parse.y: Change to allow multiple modules per source file.
10175 Allow spec modules (including quasi definitions) as well as
10177 Allow spec modules inside normal modules; these behave as if
10178 they were outermost. This violates the Blue Book, but is
10179 needed by the new grantfile mechanism. (A grant file is a
10180 spec module that gets included by the use_seize_file directive.)
10181 * ch-parse.y (struct module *current_module, push_module,
10182 pop_module): Support module nesting (for spec modules only).
10184 * ch-tree.h (struct module): New.
10185 * ch-grant.c (granted_decls): New list of declarations
10186 that have been granted into the outermode pseudo-module.
10187 * ch-grant.c (decode_mode): If the decl has a name,
10188 always write the name, not just if the decl has already
10189 been written. Since we write out all decls, we can assume
10190 it will be written later, and depend on the forward
10191 declaration kludges to catch it.
10192 * ch-grant.c (decode_decl): Don't write out _EXTERN.
10193 Instead write out standard (Blue Book) quasi-definitions.
10194 * ch-grant.c (push_granted): New function.
10195 * ch-grant.c (seize_implied_names): New function. Re-write
10196 how set element names are seized when a set type is seized.
10197 * ch-grant.c (chill_seize): Work by seraching the
10198 granted_decls list and copying the declaration.
10199 * ch-grant.c (chill_grant): Write all declarations
10200 declared in this module. Write GRANT statements for
10201 those granted. seize statements for decls seized from
10202 other modules. Write extra syntax to make a complete
10204 * ch-grant.c (grant_use_seizefile): Copy use_seize_file
10205 directives into grant file.
10206 * ch-lex.l (setup_seizefile_read): Call grant_use_seizefile.
10208 * ch-lex.l (struct input_state, current_input_state,
10209 push_input_file, pop_input_file): New (type, variable,
10210 function*2). Used to save and restore state on an input file.
10211 * ch-lex.l: Clean up to handle nested input seizefiles
10212 (needed by new grant/seize mechanism.
10213 * ch-lex.l (skip_to_end_of_directive): New function.
10214 * ch-lex.l (compiler_directive: USE_SEIZE_FILE): Make sure
10215 we skip to the end of the directive *before* we switch
10217 * ch-lex.l (setup_seizefile_read): Prevent reading the
10218 same seizefile twice (otherwise likely with new grant/seize).
10219 * ch-lex.l: Recognize SPEC. Misc cleanups.
10221 * ch-parse.y: Fixed foreward references of types.
10222 Removed the unknown_type_node crock.
10223 * ch-decl.c: Remove all uses of unknown_type_node.
10224 Check for TYPE_SIZE zero instead.
10225 * ch-decl.c (fixup_unknown_type): Make sure new mode
10226 gets copied into old mode. Merge their variant chains.
10227 * c-decl.c (lookup_name_current_level): Make non-static.
10228 * ch-decl.c (lookup_name_current_level): No longer needed.
10230 * ch-parse.y (call): Allow an implicitly defined function

10236 build_allocate_globals_memory_call): Fix names (add initial '_')
10237 and prototypes of _allocate_[global_]memory (2nd param is ref).
10238 Use build_chill_function_call, not build_function_call,
10239 so the reference parameter gets handled.
10240 * ch-actions.c. (lang_init): Make sure boolean_{true,false}_node
10241 have boolean_type_node as their types.
10242 * ch-actions.c (build_chill_lower, build_chill_upper): Fix to
10243 work for arrays with BOOLEAN_TYPE ranges (and simplify some).

10302 as-yet-undeclared types. Check for IDENTIFIER_NODE, lookup its
10303 DECL if there, pass TREE_TYPE of decl to build_pointer_type.
10304 (variantfields, varianthack): Clean up.
10305 (variantfield): Check for IDENTIFIER_NODE, lookup its DECL if
10306 there, pass TREE_TYPE of decl to grok_fixedfields.

10341 array and its type get on the permanent obstack.
10342 * ch-grant.c (write_grant_file): Don't write the _INIT=name

10346 * ch-lang.c (finish_chill_enum): Don't allocate a dummy
10347 TYPE_DECL for the enum. I don't think it is needed (?),
10348 and removing it is needed for the change above.
10350 * ch-grant.c (grant_array_type, decode_mode): Remove unused
10352 * ch-grant.ch (raw_decode_mode): New function, based on old
10354 * ch-grant.c (decode_mode); This is now just a wrapper around

10384 * ch-parse.y (structured_variable): Return NULL_TREE is invalid WITH
10385 parameter is seen, don't count it in structured_variable_list. Pre-
10386 vents seg fault when only WITH operand is invalid.
10387 * ch-parse.y (label_spec): Correct assignment within IF expression which
10388 was intended to be equality test. Remove unused variables.
10389 * ch-tree.h: Add prototype. Remove unused EXCP_CODE enumeration, and
10390 prototyping editorial comments.
10391 * ch-typeck.c: Disable generation of code to validate array index for
10392 now. Should be done as a call-back from more generic array_ref code.

10541 build_chill_length: Move VARYING array handling before regular char
10543 * ch-expr.c chill_expand_expr: Disable concatenate code - we need to
10544 the VARYING status of the target to do this correctly. Use powersetlen
10545 for the powerset operations, not a byte length.
10546 * ch-loop.c: Make CREATE_SCOPE #define to enable creation of a new scope
10547 for each CHILL loop, as Z.200 requires. Add powerset and error flags
10548 to loop structure. Evaluate user's powerset expression into a temp,
10549 scan it destructively with __ffsetclrpowerset or __flsetclrpowerset
10550 for powerset loop. Only do loop-end assignments if NOT a powerset
10551 loop, which has much less overhead now.

10724 special-case support for a BIT_FIELD_REF in right-hand-side.
10725 * ch-lang.c (finish_chill_enum): Patch up enum elements to
10726 have the correct type (instead of integers, as in C).
10728 * ch-lex.l, ch-parse.y: Add disgusting hack (involving

10769 * ch-lex.l (convert_bitstring), Changed SET_TYPE_CONSTRUCTOR to
10770 take a list of elements which are in the set. This corresponds

10785 * ch-actions.c (build_chill_binary_op): Promote short
10786 integer operands if needed (otherwise emit routines barf).

10789 * ch-parse.y (location): If IDENTIFIER is a CONST_DECL

10815 * ch-parse.y: Add working exception handling support.
10816 * ch-lex.l, ch-parse.y: Prefer standard type terminology
10817 (BOOLS, CHARS) even though non-standard (BITS, CHAR) is ok.
10818 * ch-grant.c: Fix various problems related to granting
10819 types such as bitsets.
10820 * ch-tree.c (build_bitstring_type): Set TYPE_MIN_VALUE

10824 * ch-tree.h, ch-actions.c (lang_init), ch-grant.c (decode_mode):

10827 New types chill_integer_type_node and chill_unsigned_type_node
10828 that correspond to the Chill source types INT and UINT.
10829 For now, these match the C 'short' types, but that should
10830 become a configuration option later,

10834 * ch-actions.c (build_chill_unary_op): allow NOT of a set.

10841 * ch-loop.c (begin_chill_loop, end_chill_loop): remove
10842 emit_nop() calls - they now (since exceptions) cause seg faults.

10845 * ch-tree.h: remove prototypes added to c-tree.h.

10852 * ch-tree.def: add a new tree type - just for varying array
10853 references. We were using ARRAY_REF, but the underlying C
10854 code also generates that one.
10855 * ch-convert.c, ch-expr.c, ch-typeck.c: use the new tree type.
10857 Sun Feb 7 17:33:17 1993 Bill Cox (bill@rtl.cygnus.com)

10922 * ch-tree.h: add build_chill_function_call, build_chill_slice
10923 * ch-typeck.c: add build_chill_slice()

11084 * dwarfout.c (output_type): Add hack that matches the one in the
11085 chill front end to distinquish between true string types and
11086 arrays of char, since it uses ARRAY_TYPE for both, rather than
11087 trying to use the existing support for STRING_TYPE.

11149 * chill.gperf, ch-hash.h: add Wilfried's tokens
11150 * ch-lex.l: fold in Wilfried's changes. Some tokens
11151 weren't getting recognized, and INSTANCE wasn't correctly
11152 reported to ch-parse.y as a PREDEF_MODEDCL.
11154 Thu Jan 14 15:02:39 1993 Per Bothner (bothner@cygnus.com)

11163 * calls.c, expr.c, function.c, stmt.c, varasm.c: Set
11164 MEM_IN_STRUCT_P for SET_TYPE where it is set for other aggregates
11165 * expmed.c (store_bit_field, extract_field_field): Undo
11166 yesterday's removal of MEM_IN_STRUCT_P "sanity test".
11168 * ch-decl.c (do_decls): Put back support for initializing.

11177 * ch-lex.l (convert_bitstring): Change to pack bits
11178 within words, not bytes, and to use machine bit-order
11179 (not always little-endian).
11180 * ch-parse.y: Allow BOOLS(n) as well as BITS(n).
11181 Use build_bitstring_type, not build_string_type.
11182 * expmed.c (store_bit_field, extract_field_field): Remove
11183 "sanity test" that prevents use with SET_TYPE.
11184 * tree.c (build_bitstring_type, build_powerset_type,
11185 build_string_type): Move (so far) Chill-specific functions to ...
11186 * ch-tree.c: ... new file.

11218 * modules: use gdb rather than naked-gdb, to get opcodes
11219 in chill definition.
11221 Wed Jan 6 09:48:35 1993 Bill Cox (bill@cygnus.com)
11223 * ch-typeck.c: add code to handle references to elements of VARYING
11224 arrays. Simplify chill_give_type_to_expr. Add rough draft of run-
11225 time index checking for VARYING arrays (under #if 0).

11261 Mon Jan 4 17:57:48 1993 Per Bothner (bothner@cygnus.com)
11263 * ch-grant.c, ch-parse.y: Remove all code for explicitly
11264 calling initializer functions. This is not needed, since we
11265 use the same mechanism used for C++ static constructors.
11266 * ch-grant.c (chill_start_module_code): Make sure the
11267 init_name starts with the magic string also used for C++
11268 initializers. Also, don't embed the file name in the name,
11269 just use the module name.
11270 * ch-grant.c (chill_finish_module_code): Now that the
11271 initializer name follows the standard 'collect' convention,
11272 don't need to call assembler_constructor_alias, but can
11273 use the standard assemble_constructor instead.
11274 * varasm.c (assemble_constructor_alias): Remove no-longer-
11276 * ch-parse.y: Move code that is common to the beginning of
11277 all functions to a new macro INIT_ACTION.
11278 Make sure INIT_ACTION is also done for callaction, fixing a bug.
11279 * ch-parse.y (INIT_ACTION): Do chill_start_module_code()
11280 before emit_line_note(), not after.
11282 Mon Jan 4 11:43:12 1993 Bill Cox (bill@cygnus.com)
11284 * ch-parse.y: restore requirement for :upper-bound in array decl.
11285 * ch-actions.c: enhance upper, lower, length functions for VARYING.
11287 Mon Jan 4 09:28:44 1993 Bill Cox (bill@cygnus.com)

11305 * ch-typeck.c: subtract array's lower domain value, even if
11306 index expression is constant.

11310 * ch-lex.l (convert_float): Fix misspelling in error message.
11312 Sat Jan 2 16:02:16 1993 Per Bothner (bothner@rtl.cygnus.com)
11314 * Makefile.in: Took out chill-runtime support.
11315 Chill run times are now in ../chillrt, not ./chillrt.p
11317 Sat Jan 2 15:04:13 1993 Bill Cox (bill@cygnus.com)
11319 * ch-hash.h, chill.gperf: cleanup. fewer keywords seen by ch-parse.y.
11321 Sat Jan 2 13:27:49 1993 Per Bothner (bothner@rtl.cygnus.com)
11323 * ch-lex.l (check_newline): Use the orginal versions (derived
11324 from the C code, not the simplified, special-case version).
11325 Also, fix that version of check_newline to not call yylex()
11327 * ch-lex.l (yy_input): Call check_newline to handle
11328 newlines and check for # directives.
11329 * ch-lex.l (syntax): Don't recognize #-directives; these
11330 are now handled by check_newline.
11331 * ch-actions.c (lang_init): Call the modified version of
11332 check_newline(). Do this at the *after* we've initialized
11333 standard types, so this can be done while lineno is still 0.
11335 Sat Jan 2 10:57:20 1993 Bill Cox (bill@cygnus.com)
11337 * ch-hash.h, chill.gperf: add remaining reserved words.
11339 Sat Jan 2 09:59:55 1993 Bill Cox (bill@cygnus.com)
11341 * ch-tree.h, ch-parse.y, ch-lex.l: add remaining reserved words,
11342 names for exceptions
11344 Fri Jan 1 12:30:31 1993 Fred Fish (fnf@cygnus.com)
11346 * ch-tree.h (JOINER): Define joiner character the same way
11348 * ch-grant.c (chill_start_module_code): Use JOINER character
11349 to implement name mangling for the initializer function name.
11350 Algorithm is designed to be simple, distinct from C++ mangled
11351 symbols, and easy to convert to demangled form.
11353 Thu Dec 31 10:30:51 1992 Bill Cox (bill@rtl.cygnus.com)
11355 * ch-expr.c: make array assignments work with indirect refs.
11356 * ch-actions.c: prepare for array parameter handling.
11357 * ch-loop.c, ch-parse.y, ch-tree.def, ch-typeck.c: clean up.
11359 Thu Dec 31 15:29:20 1992 Per Bothner (bothner@rtl.cygnus.com)
11361 * ch-lex.l (yy_input): Re-write to return more than one
11362 character at a time (execpt when reading seize-files).
11363 Don't increment lineno until we start reading the next line.
11364 This fixes some off-by-one errors in lineno.
11366 Wed Dec 30 16:15:23 1992 Per Bothner (bothner@rtl.cygnus.com)
11368 * ch-convert.c: Assume use of new common.c.
11369 * ch-convert.c (convert_to_reference, convert_from_reference):
11370 New routines, to handle loc-identity declared variables and
11371 LOC parameters (both of which are implemented as references).
11372 * ch-lang.c (convert_to_boolean, convert_to_char): Move to
11373 ch-convert.c, where they would seem to belong.
11374 * ch-convert.c (convert): New function, since we no longer
11375 link in c-convert.c.
11376 * ch-expr.c (chill_expand_assignment): Handle by calling
11377 convert() instead of chill_comptypes().
11378 Also handle the LHS being a reference.
11379 * ch-parse.y: Add a procedure call as an action.
11380 * ch-parse.y (locdec, optlocinit): Move handling of
11381 loc-identity declarations from optlocinit to locdec
11382 - and add working semantics for it.
11383 * ch-parse.y (seizestatement, visibilty_stmt): Simplify.
11384 * ch-parse.y (grantstatement etc): Don't bother making list.
11385 * ch-lex.l: #include <sys/types.h> before <sys/stat.h>.

11389 * ch-parse.y, ch-expr.c: add support for declaring & assigning
11391 * ch-typeck.c: allow VARYING structures in assign_type_to_expr.
11393 Tue Dec 29 15:28:48 1992 Bill Cox (bill@cygnus.com)
11395 * ch-actions.c: implement expressions of arrays of char,
11396 ( concatenation, relationals ), correct type of code parameters
11397 * ch-expr.c: correct type of code parameters
11399 Tue Dec 29 11:16:19 1992 Bill Cox (bill@cygnus.com)
11401 * ch-decl.c: cleanup.
11402 * ch-parse.y: put emit_line_note() calls in lotsa places,
11403 per Fred's request; be sure that statements get counted also.
11404 * ch-lex.l: standardize function headers.
11406 Tue Dec 29 10:41:56 1992 Fred Fish (fnf@cygnus.com)
11408 * ch-decl.c (start_chill_function): Always return 1, rather
11409 than a random value.
11410 * ch-lex.l (check_newline): Add a version for chill that
11411 just snarfs the right value for main_input_filename out of
11412 the first line of the input file, without disturbing the
11413 lexer state or requiring it's assistance.
11414 * ch-actions.c (lang_init): Call check_newline, like the
11415 other language frontends, to get main_input_filename set
11416 from first line of input file.
11418 Mon Dec 28 18:49:01 1992 Bill Cox (bill@cygnus.com)
11420 * ch-parse.y: clean up conflicts. The remaining one is
11423 Mon Dec 28 17:28:40 1992 Bill Cox (bill@cygnus.com)
11425 * ch-parse.y, ch-lex.l, ch-actions.c: add stubs for I/O,
11426 clean up some parser conflicts.
11428 Mon Dec 28 15:00:20 1992 Bill Cox (bill@cygnus.com)
11430 * ch-parse.y, ch-lex.l: add keywords and parsing for most of
11433 Sat Dec 26 20:48:23 1992 Fred Fish (fnf@cygnus.com)
11435 * chillrt/chillrt0.c: Oops, SVR4 doesn't need leading '_'
11436 on build_exceptions.
11438 Sat Dec 26 11:00:36 1992 Fred Fish (fnf@cygnus.com)
11440 * ch-grant.c (chill_finish_module_code): Call
11441 assemble_constructor_alias rather than assemble_constructor.
11442 * varasm.c (assemble_constructor_alias): New function,
11443 like assemble_constructor, but also handles the case where
11444 ASM_OUTPUT_CONSTRUCTOR is not defined and GNU ld is not
11445 being used. Emits a symbol table alias name with the correct
11446 prefix for collect to find and add to the __CTOR_LIST__.
11447 * chillrt/chillrt0.c: Build on previous hack that gets
11448 _build_exceptions into the __CTOR_LIST__, to make it work
11449 for both the non GNU-ld case and for the SVR4 case.
11451 Tue Dec 22 18:24:55 1992 Bill Cox (bill@cygnus.com)
11453 * ch-loop.c: clean up location enumeration - one more

11467 ch-loop.c: rough draft of location enumeration
11468 ch-lex.l, ch-expr.c, ch-decl.c: minor cleanup
11469 ch-actions.c: finish making pred() and succ() work.
11471 Mon Dec 21 10:04:35 1992 Bill Cox (bill@cygnus.com)
11473 * ch-actions.c: allow pred(char) and succ(char).
11475 Sun Dec 20 16:04:28 1992 Bill Cox (bill@cygnus.com)
11477 * ch-expr.c, ch-actions.c, ch-parse.y, ch-loop.c,
11478 c-expr.c: make DO WITH work.
11480 Sun Dec 20 12:22:53 1992 Bill Cox (bill@cygnus.com)
11482 * ch-loop.c, ch-actions.c, ch-typeck.c: powerset loops
11485 Sat Dec 19 14:20:23 1992 Per Bothner (bothner@cygnus.com)
11487 * c-typeck.c (process_init_constructor): Add warning if
11488 there is a duplicate default initializer element.
11489 * ch-typeck.c (chill_give_type_to_expr): New function,
11490 to handle coercion of an expression to context-given type,
11491 Takes care of untyped tuples, and case expressions.
11492 * ch-decl.c (do_decls), ch-typeck.c (chill_expand_return,
11493 chill_expand_result), ch-parse.y <assignaction>:
11494 Use chill_give_type_to_expr().
11495 * ch-typeck.c (chill_handle_case_label): New parameter list,
11496 to handle the (new) conventions for <case_label>, including
11497 default elements and ranges.
11498 * ch-parse.y <expanded_case_label>, ch-typeck.c
11499 (expand_case_expr): Use new version of chill_handle_case_label.
11500 * ch-decl.c (push_syndecls): Change parameters: Instead of
11501 TREE_LIST representing a compete <synonym definition statement>,
11502 just pass the parts of a single <synonym definition> as 3
11503 different parameters. Also, use chill_give_type_to_expr(),
11504 to handle untyped tuples in the RHS.
11505 * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct
11506 a tree - just call push_syndecls() on each <synonum_definition>
11508 * ch-parse.y (exprlist_get_single): Remove; no longer needed.
11509 * ch-parse.y: Handle <tuple> without mode name diferently from
11510 <tuple> with mode name. The latter is a <primval> that can be
11511 in most contexts, but if the <mode name> is missing, the <tuple>
11512 is only allowed in certain contexts. Use the new non-terminal
11513 <untyped_expr> to indicate those contexts where untyped tuples
11514 (and case expressions) are valid because the expression gets a
11515 type from its context (such as the RHS of an assignment).
11516 Use chill_give_type_to_expr in those contexts.
11518 Sat Dec 19 14:01:26 1992 Bill Cox (bill@cygnus.com)
11520 * ch-actions.c, ch-loop.c, Makefile.in: looping stuff.

11529 * ch-actions.c (maybe_chill_comptypes): Delete unused
11531 (chill_comptypes): Add new parameter ERRSTR. All callers
11533 (build_chill_binary_op): Fix indentation to match GNU coding
11536 Fri Dec 18 08:18:13 1992 Bill Cox (bill@rtl.cygnus.com)
11538 * ch-parse.y, ch-expr.c, ch-actions.c, expr.c: major

11550 (as in '(else):' and '(*):' ).
11552 * ch-parse.y: Previous change to dis-ambiguate case-labels
11553 seems to have allowed getting rid of all of the expr_or_list hair.
11554 * ch-decl.c (do_decls): Undo Tiemann's change to "Handle
11555 initialization of multiple variables by a tuple" - the
11558 Wed Dec 16 11:17:53 1992 Bill Cox (bill@cygnus.com)
11560 * ch-parse.y: complete re-write of DO statement handling.
11561 now operational, except WITH is stubbed out. Improved
11562 syntax error message.
11563 * ch-actions.c: DO support: high_domain_value(), low_domain_value ().
11564 * ch-expr.c: fixes to IN_EXPR handling.
11566 Tue Dec 15 17:15:13 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11568 * ch-grant.c: Add casts to alloca return to avoid compiler warning.

11634 * c-typeck.c (process_init_constructor): Warn about duplicate
11635 labels for labelled initializer elements.
11636 * ch-lex.l (various operator tokens, such as "+"): Don't
11637 set yylval.code to a TREE_CODE; this is better done in parser.
11638 * ch-parse.y: Some work with case labels and tuples.
11639 Get literal range as tuple (and case) labels working.
11640 Fix some problems introduced by recent grammar overhaul.

11644 * ch-actions.c, ch-parse.y ch-tree.h ch-expr.c, ch-typeck.c:
11645 got long, real expressions working. We can also call a func-
11646 tion and use its return value.
11648 Thu Dec 10 14:45:17 1992 Per Bothner (bothner@cygnus.com)
11650 * ch-parse.y: Major change to remove or at least identify
11651 parser ambiguities. One result: We now allow actions that
11652 start with '(', as required by teh Blue Book. This does break
11653 some things; look for FIXME for things that need work.
11654 * ch-typeck.c (chill_expand_case_expr): We need an extra
11655 level of looping to (in the future) support <case label
11656 specification>s with more than one <case label list>.

11685 indicate we are done with initialization.
11687 * ch-decl.c (do_decls): Set TREE_PUBLIC if we are doing a
11689 (start_chill_function): Ditto.
11691 * ch-lex.c (convert_bitstring): Set TREE_CONSTANT.

11693 equality comparison operators.
11695 * ch-parse.y: Clear CURRENT_LOCNAMELIST after calling do_decls.

11708 * tree.def: Move CARD_EXPR and SET_LE_EXPR back down with the other
11709 Pascal-required ones, since C++ no longer needs them. When
11710 Chill's public, a comment can be added to the effect that
11711 SET_LE_EXPR is also used by Chill.
11713 Fri Dec 4 12:05:01 1992 Bill Cox (bill@cygnus.com)
11715 * Restore CARD_EXPR and SET_LE_EXPR to tree.def.

11754 (push_newmode,push_synmode): Call `fixup_unknown_type' when we
11755 see a declaration that uses `unknown_type_node'. FIXME.
11757 * ch-grant.c (decode_constant): New function.
11758 (decode_decl): Call `decode_constant' for CONST_DECLs.
11760 * ch-lex.l (char action): Use ridpointers instead of
11761 lookup_name to get "char"'s declaration.
11763 * ch-parse.y: Call `build_lang_decl' instead of `build_decl'
11764 when we need to build a TYPE_DECL.
11766 Tue Dec 2 09:44:05 1992 Bill Cox (bill@cygnus.com)
11768 * ch-typeck.c: clean up a gcc warning with a forward
11769 declaration of build_string_type.
11771 Tue Dec 1 16:51:05 1992 Bill Cox (bill@cygnus.com)
11773 * ch-actions.c: completely remove those builtin calls
11774 that are duplicated in c-decl.c
11776 Tue Dec 1 16:38:51 1992 Fred Fish (fnf@cygnus.com)
11778 * ch-actions.c (lang_init): Ifdef out initializations for
11779 __builtin_abs and __builtin_fabs, since they are duplicates of
11780 initializations in c-decl.c, and trigger spurious warnings.
11782 Tue Dec 1 16:35:18 1992 Bill Cox (bill@cygnus.com)
11784 * ch-parse.y: make size() work with a typename argument.

11813 * chillsh: New script frontend (ala g++), installed as "chill".
11814 Can't be called "chill.sh" because make tries to cat it into the
11815 "chill" directory. Can't be called just "chill" cause that's
11816 already there as a directory.
11817 * Makefile.in: Add rules to install chillsh as "chill".
11818 * chill/libchill.c: Temporarily ifdef out stuff that wants
11819 to conflict with i486/SVR4 runtime or wants to pull in librmt.a,
11820 which itself causes linkage to fail.
11822 Mon Nov 30 16:28:19 1992 Bill Cox (bill@cygnus.com)
11824 * ch-lex.l: added keywords for TRUNC, ROUND, FLOAT, LFLOAT
11825 conversion routines.
11826 * ch-parse.y: added %tokens for TRUNC, ROUND, FLOAT, LFLOAT.
11827 Added production for SIZE(expr).

11832 * ch-lex.l, ch-parse.y: Translate token PFEIL into English ARROW.
11833 * ch-parse.y (op6): Remove handling of string repetition operator,

11848 pred, succ, etc. Put flex -a option into Makefile.in, so we can
11849 clean up the lexer soon.

11853 * ch-typeck.c (chill_handle_case_label, chill_handle_case_default):
11854 New functions, for code common to CASE actions and expressions.
11855 * chill.y: Replace some code by calls to chill_handle_case_label
11856 and chill_handle_case_default.
11857 * ch-typeck.c (chill_expand_case_expr): Add semantics.
11859 * tree.c: Change doing_chill_thang from extern to common.

11865 * ch-typeck.c (chill_expand_case_expr): New function.
11866 Placeholder to implement case expressions.
11867 * ch-typeck.c (chill_expand_result, chill_expand_return):
11868 Handle mode-unspecified tuples and case expressions in
11869 the context of RETURN and RESULT actions.
11870 * chill.y (assignaction): Handle case expressions in the
11871 context of the RHS of an assignment action.
11872 * chill.y (caseaction): Remove spurious duplicate OF in grammar.
11873 * chill.y: Handle labeled structure tuples.
11874 * chill.y: New rules to parse CASE expressions.
11875 * tree.c (build_function_types): Allow Chill functions
11876 to return arrays and functions.

11881 tuple (constructor) given an expected (context) type.
11882 * chill.y: Implement 'LHS := TUPLE' using expand_chill_tuple,
11883 using the mode of the LHS and the expected type of the TUPLE.
11884 * chill.y: Implement initialization.
11885 * chill.y: Fix some syntax bugs (forbidlist must be surrounded
11886 by parentheses), and remove or note ambiguities.
11887 * chill.y: Started converting layout style to be like c-parse.in.
11888 * chill.y: Implement IF expressions.
11889 * chill.y: Added syntax rules for tuples. Labelled and unlabelled
11890 array tuples should now work (in some contexts).
11891 * ch-actions.c: Initialize doing_chill_thang to 1.
11892 * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
11893 initializer, to make pushdecl and finish_decl work.
11894 * c-decl.c (convert_for_assignment): If Chill, don't convert
11895 function and arrays into pointers. (Maybe functions should
11896 still be converted?)
11897 * c-typeck.c (grokdeclarator): Allow functions in Chill
11898 to return arrays and functions.
11900 Mon Nov 16 15:40:47 1992 Per Bothner (bothner@rtl.cygnus.com)
