2995 Check string_assignment_condition for varying strings too.
2997 * typeck.c (build_chill_cast): If the types have different sizes,

3019 * parse.c: Don't always keep a valid token in terminal_buffer[0].
3020 The extra look-ahead may have made the parser faster, but caused
3021 some problems synchronizing with the lexer. Specifically:
3022 (PEEK_TOKEN): Now calls an optimized variant of peek_token_(0).

3441 * grant.c (format_character, find_assoc): Removed.
3443 * decl.c (do_decl): Add missing TREE_CHAIN.
3445 * decl.c (finish_incomplete_decl): Removed.
3446 (init_decl_processing): Don't set incomplete_decl_finalize_hook.
3447 (finish_decl): Remove old C-specific code to deduce size of
3448 array from initialization.
3449 (complete_array_type): Just make it abort.
3451 * except.c (finish_handler_array): Avoid calling C-specific kludge
3452 complete_array_type.
3454 * convert.c (digest_constructor): Rename, and re-write to:
3455 (digest_array_tuple, convert): No longer use the code in
3456 ../c-typeck.c; use a Chill-only implementation (sigh).
3458 * typeck.c (chill_expand_tuple): Remove unneeded call to
3459 complete_array_type.
3461 * expr.c (fold_set_expr), grant.c (decode_constant),
3462 typeck.c (expand_constant_to_buffer): Update name of called
3463 function unpack_set_constructor to get_set_constructor_bits.
3464 * expr.c (powersetlen ): Remove redundant call to convert.
3466 * ch-tree.h (unpack_set_constructor): Removed obsolete declaration.
3468 * inout.c (build_chill_writetext): Handle 64-bit integer literals
3469 by trying to convert them to a smaller type.
3471 * lex.l (convert_number): Always use long long type (possibly
3472 unsigned) to avoid problems with constant folding truncation.
3474 Mon Sep 5 08:08:22 1994 Wilfried Moser (moser@rtl.cygnus.com)
3476 * ch-tree.h (enum chill_built_in_function): Add BUILT_IN_QUEUE_LENGTH.
3477 Add new prototype (see tasking.c).
3479 * expr.c (build_generalized_call): Add processing of
3480 BUILT_IN_QUEUE_LENGTH.
3482 * tasking.c (build_queue_length): New function.
3484 * tasking.c (tasking_init): Add new external function definition.
3486 Thu Sep 1 15:38:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3488 * lex.l (default_lex): New function. Progress towards
3489 getting rid of [f]lex.
3491 * lex.l (convert_number): Use mul_double and add_double.
3492 Set result type to a reasonable type in which the literal
3493 will fit. Give error message if literal is too big.
3495 * lex.l (equal_number): Switch (temporarily) to permanent obstack.
3497 * typeck.c (build_chill_slice_with_range): Check for empty
3498 slice *after* we have checked for upper/lower limit in range.
3500 * grant.c (decode_mode): Remove unused code. (BOOL and
3501 CHAR ranges are represented as INTEGER_TYPEs.)
3503 * tasking.c (build_process_header): Add missing call to
3504 expand_start_bindings.
3505 * parse.c (end_function): Add missing expand_end_bindings.
3507 Wed Aug 31 17:25:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3509 * decl.c (init_decl_processing): Set set_alignment.
3511 Tue Aug 30 16:40:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
3513 * actions.c (print_missing_cases, check_missing_cases,
3514 BITARRAY_TEST, BITARRAY_SET): New functions and macros,
3515 to check for completeness of case actions and expressions.
3516 * decl.c (c_decode_option, init_decl_processing):
3517 Don't set warn_switch.
3518 * expr.c (chill_expand_case_expr): Call check_missing_cases
3519 instead of check_for_full_enumeration_handling.
3520 * parse.c (parse_case_actions): Call check_missing_cases.
3522 * expr.c (build_chill_binary_op): Remove some dead code.
3523 * expr.c (chill_truthvalue_conversion): Call build_chill_binary_op
3524 instead of build_binary_op.
3525 * ch-tree.h (binary_op_error, build_binary_op): Unused. Removed.
3527 * parse.c (end_function): Use kept_level_p in parameter to
3528 poplevel. This reverts a June 13 change.
3530 Fri Aug 26 11:50:19 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3532 * configure: Ignore --without, as ../configure does.
3534 Wed Aug 24 01:17:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3536 * lex.l: Change rule for decimal numbers to allow identifiers
3537 to start with an underscore (_).
3539 Fri Aug 19 16:38:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
3541 * tasking.c (build_receive_signal_case_label): Remove backwards
3542 chill_convert_for_assignment (which converted whatever garbage
3543 was in the *target* to the type of the signal argument!).
3545 Fri Aug 19 07:10:43 1994 Wilfried Moser (moser@rtl.cygnus.com)
3547 * inout.c (build_chill_io_list_type, build_enum_tables),
3548 tasking.c (build_tasking_struct): Temporarily reset
3549 maximum_field_alignment to 0, so that the compiler-built
3550 data structures needed by the RTS can be independent of -fpack.
3552 Thu Aug 18 13:39:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3554 * typeck.c (build_init_struct): Temporarily reset
3555 maximum_field_alignment to 0, so that the compiler-built
3556 data structures needed by the RTS can be independent of -fpack.
3558 Wed Aug 17 23:48:33 1994 Wilfried Moser (moser@rtl.cygnus.com)
3560 * parse.c (parse_primval, expect, parse_on_exception_list):
3561 Print error message only in pass 2.
3563 Wed Aug 17 13:47:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3565 * decl.c (switch_to_pass_2): Revert June 13 change,
3566 (Don't exit after pass 1 if an error was found.)
3568 * ch-tree.def (SLICE_EXPR): New tree-code.
3569 * typeck.c (build_chill_slice): For building a slice of a
3570 bit-string, just generate a SLICE_EXPR.
3571 * decl.c (init_decl_processing): Declare __pscpy.
3572 * actions.c (chill_expand_assignment): Handle a SLICE_EXPR
3573 on the LHS of assignment, by calling __pscpy.
3574 * expr.c (chill_expand_expr): Handle SLICE_EXPR (as a RHS
3575 value) by using __psslice to copy slice to a temp.
3577 Wed Aug 17 05:52:44 1994 Wilfried Moser (moser@rtl.cygnus.com)
3579 * Make-lang.in: Change version of GNUCHILL compiler to 1.4.1.
3580 * expr.c (build_chill_length): Enable LENGTH built-in to process
3581 Buffers and Events too (Z.200/1992).
3582 * lex.l (yywrap): Always set yyin to finput and/or grt_in. On
3583 a linux system the previous version was not able to run.
3584 * tasking.c: Correct processing of infinite buffer- and event-length
3585 to avoid RANGEFAIL warning.
3587 Thu Aug 11 11:46:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3589 * parse.c (parse_if_expression_body): Don't call the C-specific
3590 build_conditional_expr. Just do build_nt (COND_EXPR, ...).
3591 * convert.c (convert): Convert a COND_EXPR by converting
3594 * convert.c (convert): Don't call convert before
3595 convert_to_reference. It's apt to do weird and unneedful things.
3596 * convert.c (convert): If the expression is varying, just call
3597 varying_to_slice, which simplifies quite a bit.
3599 * ch-tree.h (varying_to_slice): Add prototype.
3600 * typeck.c (varying_to_slice): Remove prototype.
3602 * satisfy.c (satisfy): Move case PAREN_EXPR from type 'e'
3605 * except.c (emit_setup_handler): Temporarily reset the
3606 maximum_field_alignment to zero so the compiler's exception
3607 data structures can be compatible with the run-time system,
3608 even when we're compiling with -fpack.
3610 * expr.c (compare_records): Call saved_if_needed on operands.
3612 * expr.c (build_set_expr case NE_EXPR): Don't use __nepowerset
3613 which has been reimplemented to just call __eqpowerset and
3614 invert the result. Inline this new implementation by
3615 handling as EQ_EXPR, and inverting the result.
3616 * decl.c (init_decl_processing): Don't define unused __eqpowerset.
3618 * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
3619 type boolean_type_node, not void_type_node. (Fixing this
3620 avoids a crash in the back-end.)
3622 * grant.c (decode_constant): In a CALL_EXPR, if the argument
3623 list is not a TREE_LIST (as in string repetiation), don't
3626 Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3628 * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
3629 CONST_DECL is from a SET definition. (This is safer than
3630 checking that the type is ENUMERAL_TYPE, because synonym
3631 definitions may have a NULL TREE_TYPE.)
3632 Also, if we have duplicate enums whose types are identical,
3634 * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
3635 an extra 'quiet' parameter, which is true if we're called from
3636 bind_sub_modules. (In that case an error message about duplicated
3637 decls would be repeated later, so suppress it.)
3639 * parse.c (stmt_count): Removed, not used.
3640 (INIT_ACTION): Call emit_line_note only if !ignoring.
3641 (parse_begin_end_block): Do INIT_ACTION even if ignoring.
3643 Fri Aug 5 12:39:11 1994 Per Bothner (bothner@kalessin.cygnus.com)
3645 * parse.c (parse_untyped_expr): Add missing semi-colon.
3647 Thu Aug 4 17:40:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
3649 * parse.c (parse_untyped_expr): Fix various problem for the
3650 case that we see a '(': Add missing 'case' keyword.
3651 Only recurse if '(' is followed by 'if', 'case' or '[',
3652 and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
3654 * parse.c (parse_send_action): Remove extra nreverse.
3656 Thu Jul 28 04:00:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3658 * expr.c (build_allocate_global_memory_call, build_allocate_memory_call):
3661 Tue Jul 26 22:48:15 1994 Michael Tiemann (tiemann@blues.cygnus.com)
3663 * parse.c (parse_untyped_expr): Added missing "case" before LPRN.
3664 Added a missing call to `require' as well.
3666 Tue Jul 19 10:30:12 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3668 * lex.l (yywrap): Define as yywrap_chill to avoid conflicts with
3669 the extern declaration in the flex skeleton.
3671 Mon Jul 18 23:06:04 1994 Per Bothner (bothner@kalessin.cygnus.com)
3673 * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
3674 Check the type of the instance expr using CH_COMPATIBLE,
3675 and not just == instance_type_node. (This allows
3676 the expression to have mode READ INSTANCE).
3677 * tasking.c (build_instance_type): Give instance_type_node
3678 a non-null novelty (i.e. different from a struct).
3679 * tasking.c (build_receive_case_start, build_delay_case_start):
3680 Check that for a location using CH_LOCATION_P.
3682 Mon Jul 18 13:22:23 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
3684 * expr.c (finish_chill_unary_op): Use TREE_SET_CODE not TREE_CODE
3685 to modify a tree code.
3687 Mon Jul 18 11:24:57 1994 Bill Cox (bill@rtl.cygnus.com)
3689 * convert.c (digest_structure_tuple): Fix thinko in TREE_CODE
3692 Mon Jul 18 05:40:15 1994 Doug Evans (dje@canuck.cygnus.com)
3694 * decl.c (warn_bad_function_cast): Define so cc1chill will link.
3696 Thu Jul 14 18:37:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3698 * parse.c (parse_send_action): Do tree_cons *before* checking
3701 Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3703 * convert.c (digest_structure_tuple): Don't use convert to
3704 coerce initial value, use chill_convert_for_assignment instead.
3705 (Thus we also get range_checking.)
3707 * expr.c (build_chill_card): Use force_addr_of instead of
3708 build_chill_addr_expr.
3710 * loop.c (build_temporary_variable): Stylistic tweak.
3711 * loop.c (maybe_make_for_temp): Initialize temp using
3712 explicitly, not using assignment. Avoids a problem if
3713 the expression is read-only.
3714 * typeck.c (smash_dummy_type): Always used the saved TYPE_NAME
3715 and CH_NOVELTY_FLAG.
3717 Wed Jul 6 20:12:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3719 * expr.c, ch-tree.h (finish_chill_unary_op): New function,
3720 based on code ripped out of build_chill_unary_op.
3721 (build_chill_unary_op): Call finish_chill_unary_op unless pass==1.
3722 * satisfy.c (satisfy): Call finish_chill_unary_op when needed.
3724 Mon Jun 27 11:29:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3726 * tree.c (save_if_needed), ch-tree.h: New function.
3727 * typeck.c (build_chill_slice_with_range,
3728 build_chill_slice_with_length): Call save_if_neeed on array arg.
3729 * expr.c (varying_to_slice): Re-write to use save_if_needed.
3731 * typeck.c (extract_constant_from_buffer): Handle BOOLEAN_TYPE.
3733 Mon Jun 27 01:11:10 1994 Wilfried Moser (moser@rtl.cygnus.com)
3735 * inout.c (build_chill_io_list_type): Change layout of __tmp_WIO_list
3736 that it is always the same, regardless if compiled with -fpack
3739 Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3741 * lex.l (yywrap): Kludge to work around mis-synchronization
3742 between lexer (which read ahead) and parser: Don't emit
3743 (left-over) uze_seizefile directives at the end of file.
3745 * typeck.c (build_chill_array_ref): Allow the derived
3746 array indexing syntax for arrays of bit strings.
3747 Add a comment explaining why.
3749 * typeck.c, ch-tree.h (string_assignment_condition): Change
3750 the interface. Return a boolean expression (which can be
3751 used in a conditional at run-time); never expand anything.
3753 * actions.c (chill_convert_for_assignment): Check
3754 string_assignment_condition here, rather than in callers.
3755 * actions.c (chill_expand_assignment): Don't need to check
3756 string_assignment_condition here.
3757 * expr.c (build_chill_function_call): Likewise.
3758 * satisfy.c (safe_satisfy_decl): Update accordingly.
3759 * decl.c (do_decl): Simplify testing and conversion by
3760 deferring everything to chill_convert_for_assignment.
3762 * parse.c: Combine the two variables 'ignore_exprs' and
3763 'ignore_actions' into one variable called 'ignoring'.
3764 * ch-tree.h: Add 'extern int ignoring'.
3765 * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
3766 Rename ignore_actions and ignore_exprs to ignoring.
3767 Remove unneeded extern declarations.
3768 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3769 build_chill_arrow_expr, build_generalized_call, build_delay_action,
3770 build_buffer_type, build_event_type): I changed my mind. It is
3771 cleaner to check for 'ignoring' in the parser, rather than here.
3772 * parse.c (parse_action, parse_primval, parse_opt_mode):
3773 Therefore we must check for ignoring here.
3774 * parse.c (parse_loc_declaration): Set ignoring in pass 2
3775 when parsing the mode.
3777 * tasking.c (generate_tasking_code_variable): Do arithmetic
3778 on signal_code etc using unsigned rather than signed shorts.
3780 * grant.c (static char* current_grant_modename): Removed.
3781 * grant.c (decode_decl case CONST_DECL): Remove error message.
3783 * Make-lang.in (CHILL_SRCS): Add $(srcdir)/ch/parse.c.
3784 * Makefile.in: Fix dependencies for parse.o.
3785 Remove some duplicate dependencies for $(TREE_H).
3787 Mon Jun 13 14:25:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3789 * typeck.c (build_chill_cast): Allow a value cast between
3790 non-discrete object of the same size, but with a pedwarn.
3791 * typeck.c (bit_string_assignment_condition,
3792 char_string_assignment_condition): Merge near-duplicate functions
3793 and place the code in string_assignment_condition.
3795 * decl.c (parm_flag, declare_parm_level, in_param_level_p):
3797 * decl.c (start_chill_function, finish_chill_function): Make
3798 parameter level have same nesting level as body, as required by Z200.
3799 * decl.c (switch_to_pass_2): Always exit if an error has been found.
3800 * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
3801 generated from GRANT ALL.
3802 * decl.c (lookup_name_for_seizing): Don't seize from
3803 the nesting level of builtins (predefined objects).
3804 * decl.c (lookup_name_for_seizing): Make more robust on error.
3806 * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
3807 be 'RESULT' (or 'result'). This makes it more accessible from gdb.
3808 Also, use do_decl to declare it, so that debugging symbols are
3809 generated. And, re-arrange so that actions that need to
3810 be done both passes (such as push_levels) use the same code.
3812 * parse.c (get_type_of): If ignore_exprs, don't lookup name.
3813 * parse.c (end_function): Fix poplevel params.
3814 * parse.c (expect): Don't read forwards on an error.
3815 * parse.c (parse_field): Don't define two tag_list locals!
3816 * parse.c (parse_pass_1_2): Better error message.
3818 * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
3819 parse_opt_mode, rather than vice versa. If parse_opt_mode
3820 returns NULL_EXPR, then parse_mode gives an error.
3821 Change parse_opt_mode (and any functions it calls) to only
3822 return NULL_TREE if there is no mode (even on ignore_exprs).
3823 (parse_set_mode, parse_structure_mode, parse_procedure_mode):
3824 Never return NULL_EXPR.
3825 * tasking.c (build_buffer_type, build_event_type): Return
3826 void_type_node instead of NULL_EXPR if ignore_exprs is true.
3828 * parse.c (parse_synonym_definition): Call parse_untyped_expr
3829 only if we have a mode.
3830 * parse.c (parse_send_action): Parse list of untyped_expr's,
3831 rather than a list of (typed) expressions.
3832 * parse.c (parse_primval): Emit error if '[' seen without
3833 preceding mode name. (If this is to be allowed, call
3834 parse_untyped_expr instead.)
3836 * parse.c (parse_array_index): Renamed to ...
3837 (parse_index_mode): ... to match Z200 terminology.
3838 Re-write to resolve some of the nastier ambiguities,
3839 and allow things like ' CHAR(10) : CHAR(20) '.
3841 * parse.c (parse_tuple_element): Change interface to return
3842 reversed list, so don't call nreverse.
3843 * parse.c (parse_tuple): No longer nreverse element list here.
3844 * parse.c (parse_opt_element_list): Do nreverse here instead.
3845 * parse.c (parse_case_label_list): Call nreverse at end.
3847 Fri Jun 10 15:36:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
3849 * typeck.c (chill_similar): Remove bogus "else".
3851 Wed Jun 8 00:01:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
3853 * ch-tree.h (TYPE_ARRAY_MAX_SIZE): New macro (and comment)
3854 to make it clearer that we are using TYPE_MAX_VALUE in a special way.
3855 * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
3856 * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
3857 * convert.c (convert): When converting a fixed string/array
3858 to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
3859 of (the type of) the padding.
3860 * convert.c (convert): If the concatenation is non-constant, use
3861 the low-level 'build' to set the type of the result (which is usually
3862 a fixed-size array) rather than depend on build_chill_binary_op
3863 to figure it out (it's unable to simplify the size to a constant).
3865 Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
3867 * lang.c (lang_decode_option): Let -fspecial_UC imply
3868 -fno-ignore-case without requiring it explicitly.
3869 * lang.c (lang_decode_option): Support (experimentally)
3870 the -fpack and -fno-pack flags.
3872 Thu Jun 2 20:49:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3874 * configure: Add support for --program-prefix and --program-suffix.
3876 Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3878 * convert.c (digest_constructor): Check that initial value
3879 is compatible with element mode before calling convert.
3880 * typeck.c (chill_compatible): A string mode is not compatible
3881 with an untyped constructor.
3882 * decl.c (do_decl): Clean up error messages. Use error_with_decl.
3884 * ch-tree.h: Fix inconsistencies: bool_true_node ->
3885 boolean_true_node, and bool_false_node -> boolean_false_node.
3886 * typeck.c (valid_array_index_): Minor simplification.
3888 Tue May 31 04:33:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3890 * inout.c (build_chill_writetext): Add correct processing
3891 of POWERSET RANGE (setmode).
3893 * lex.l (same_file): Add searching for file(s) in
3896 Fri May 27 14:22:42 1994 Per Bothner (bothner@kalessin.cygnus.com)
3898 * Make-lang.c (CHILL.mostlyclean, CHILL.distdir): Don't list
3899 yacc/bison output files, since the grammer is no longer in yacc.
3900 * config-lang.in (diff_excludes): Likewise.
3902 Thu May 26 16:38:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3904 * gperf, hash.h, lex.l, parse.h: Rename PROCESS_TYPE token
3905 (in some files spelled PROCESS_TYPE_ to avoid clashes
3906 with the PROCESS_TYPE tree_code) to PROCESS_TYPE_TOKEN.
3908 Thu May 26 02:18:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3910 * timing.c (build_cycle_start): Change call to __define_timeout.
3911 * decl.c (init_decl_processing): Change definitions of
3912 __define_timeout and __wait_timeout.
3914 Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
3916 Replace yacc-based parser with a recursive-decent parser.
3917 (This may seem backwards, but Chill [like C++] is not a
3918 language that is remotely LALR(1). Using a R-D parser
3919 allows us to use look-ahead and to back-up to resolve the
3920 difficult ambiguities.)
3922 * parse.c, parse.h: New files, containing new r-d parser.
3923 * Makefile.in: Update accordingly.
3924 * actions.c (chill_convert_for_assignment): Don't return
3925 NULL_EXPR if ignore_exprs is true. It simplifies the parser
3926 if we consistently reserve NULL_EXPR for a missing expression.
3927 * expr.c (build_chill_function_call): Likewise.
3929 * lex.l: Tweaks for new parser.
3930 * lex.l (prepare_paren_colon, paren_paren_colon_level,
3931 paren_level): Ugly hack no longer needed.
3933 * expr.c (build_chill_function_call): Cleanup.
3934 Call chill_convert_for_assignment to convert IN/INOUT
3935 paramaters on both input and output. For LOC parameters,
3936 give error if actual is a non-referable location.
3937 * actions.c (convert_for_assignment): Add new parameter (a
3938 "place" string used in error messages).
3939 * actions.c (adjust_parm_or_field): Removed.
3940 * actions.c (chill_expand_assignment): Take just a single LHS,
3941 and move support for multiple assignments to ...
3942 (expand_assignment_action): ... here. Some cleaning up.
3943 * timing.c (build_cycle_start): Adjust accordingly.
3944 * actions.c (expand_assignment_to_varying_array): Likewise.
3945 * tasking.c (many places): Ditto.
3946 * ch-tree.h: Fix declarations appropriately.
3948 * parse.c (parse_defining_occurrence_list): Return a single
3949 IDENTIFIER_NODE (instead of a singleton list) in the common
3950 case. Minor complication to save a minor amount of space.
3951 * decl.c (do_based_decls): Move guts of code into ...
3952 (do_based_decl): ... this new function.
3953 * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
3954 * decl.c (push_syndecl): Replace by ...
3955 (push_syndecl): ... (which only supports a single name).
3956 (push_modedef): Only handle a single name.
3957 * tasking.c (build_process_header, build_signal_struct_type):
3960 * expr.c (build_generalized_call): Handle string repetition.
3961 * expr.c (build_chill_repetition_op): Change interface.
3962 * grant.c (decode_constant): Allow parameter list to be
3963 a non-TREE_LIST. (Used for string repetition.)
3965 Wed May 25 11:28:48 1994 Per Bothner (bothner@kalessin.cygnus.com)
3967 * lex.l (make_identifier): Replaced by ...
3968 (read_identifier, handle_name): ... new functions.
3969 * lex.l: Parse an identifiers using read_identifier using
3970 read_identifier and handle_name, rather than having [f]lex
3971 do it. (One reason is that lex uses a fixed-size buffer.)
3973 * lex.l (read_directive, skip_directive): New functions.
3974 Use them to parse compiler-directives, instead of rather
3975 ugly and useless use of lexer start conditions.
3977 Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3979 * decl.c (unnamed_module_number): Renamed to ...
3980 (module_number): .. and make non-static.
3981 (push_module): Always increment module_number.
3982 * lex.l (yywrap): Print warning if no modules seen.
3984 * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
3985 decl to current_seizefile_name (which is unreliable).
3986 * grant.c (chill_grant): Set it here instead.
3988 * expr.c (fold_set_expr): Use int_size_in_bytes instead of
3989 TYPE_PRECISION (which is not defined for a SET_TYPE).
3991 Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
3993 Cleanup to remove need for variables in common storage.
3994 * decl.c: Remove unused use of current_obstack.
3995 * actions.c (maybe_chill_check_decl): Remove unused function.
3996 * actions.h, lang.c: Remove uses of doing_chill_thang.
3997 * ch-tree.h (void_list_node): Make extern (rather than common).
3998 * decl.c (void_list_node): Add definition.
4000 Thu May 19 06:54:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
4002 * configure (build): Build canon_host and canon_target
4003 to pass it to all subsequently generated Makefiles (needed
4004 for testsuite/execute in case of cross build).
4006 Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4008 * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
4009 the input type, which loses with the no-longer-new 2-pass
4010 implementation, since the input "type" could be an IDENTIFIER_NODE.
4011 * grant.c (raw_decode_mode): Rename to decode_mode.
4013 Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
4015 * typeck.c (chill_location): Neither a STRING_CST nor a
4016 CONSTRUCTOR is a location.
4017 * typeck.c (chill_root_mode): Convert a function to a
4018 pointer-to-function.
4019 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
4020 build_chill_arrow_expr): If ignore_exprs, return operand
4021 rather than NULL_EXPR. This makes it easier for the parser to
4022 distinguish missing expressions.
4023 * expr.c (build_max_min): Convert the lower bound of a
4024 set to a long before calling run-time routine.
4025 * expr.c (build_chill_pred_or_succ): Use discrete_type_p
4026 to check the argument type.
4027 * expr.c (build_chill_arrow_expr): If argument is not a location,
4028 do a predwarn if it is a STRING_CST or has function type.
4030 Tue May 17 06:05:13 1994 Wilfried Moser (moser@rtl.cygnus.com)
4032 * configure (build): Remove building of canon_host and canon_target.
4033 It doesn't work in any case.
4035 Mon May 16 02:10:35 1994 Wilfried Moser (moser@rtl.cygnus.com)
4037 * configure (build): Build canon_host and canon_target
4038 to pass it to all subsequently generated Makefiles (needed
4039 for testsuite/execute in case of cross build).
4040 * Make-lang.in (chill-runtime): Change chill to CHILL in the case
4041 statement to build chill-runtime automatically.
4043 Mon May 9 15:30:08 1994 Doug Evans (dje@canuck.cygnus.com)
4045 * Makefile.in (FLAGS_TO_PASS): Define.
4047 (../cc1chill): Depend on $(OBJDEPS) $(C_OBJS).
4048 * Make-lang.in (cc1chill): Delete dependency on $(OBJS) $(BC_OBJS).
4049 (CHILL.mostlyclean): Use `mostlyclean' as recursive target.
4051 Sun May 8 13:05:00 1994 Per Bothner (bothner@cygnus.com)
4053 * Make-lang.in (cc1chill): Should not depend on libgcc.a.
4055 Thu May 5 18:58:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
4057 * decl.c (copy_lang_decl): New (dummy) function.
4059 Mon May 2 14:33:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
4061 * parse.y (sendaction): Fix thinko (in sense of condition).
4062 * tasking.c (build_receive_case_label): Another thinko.
4064 * parse.y (optsigdest): Force ignore_exprs to 0 while parsing
4067 * decl.c (build_chill_function_type): Don't call layout_type
4068 (since that may prevent parameter or result types being
4069 properly satisfied).
4070 * satisfy.c (satisfy): Layout FUNCTION_TYPEs.
4071 * parse.y (procmode): Call build_chill_pointer_type, rather
4072 than build_pointer_type (which incorrectly sets TYPE_SIZE).
4074 * parse.y (get_type_of): Handle TYPE_DECL (again).
4075 * parse.y (optresultspec): Call build_chill_reference_type, rather
4076 than build_reference_type (which incorrectly sets TYPE_SIZE).
4077 * parse.y (range_or_mode): Rename to plain range, since it
4078 no longer matches modename.
4079 * actions.c (chill_handle_case_label_range): New function, with
4080 functionality moved out of chill_handle_case_label.
4081 * actions.c (chill_handle_case_label): Handle here the case that
4082 the label_value is a TYPE_DECL (modename). Also clean up some.
4083 * typeck.c (build_chill_slice_with_length): Convert max_index
4084 to the type of min_value. (Old code broke on varying strings.)
4086 Sun May 1 13:53:36 1994 Doug Evans (dje@canuck.cygnus.com)
4088 * Makefile.in (BC_OBJS): Delete all references
4089 (OBJS): Cat ../stamp-objlist to get language independent files.
4090 (../cc1chill): Delete dependency on $(OBJS).
4091 * Make-lang.in (cc1chill): Depend on stamp-objlist.
4093 Sat Apr 30 14:50:15 1994 Per Bothner (bothner@kalessin.cygnus.com)
4095 * lex.h, lex.c: Remove lastiddecl.
4096 * lex.l (name_type_signal): Simplify. We no longer check for
4097 TYPENAME or SIGNALNAME (which was unreliable with two passes).
4098 Also rename to make_identifier.
4099 * parse.y: Cleaned up grammar to not need SIGNALNAME or TYPENAME.
4100 * Makefile.in (stamp-parse); One conflict fewer!
4101 * parse.y (rccase_label_flag): Moved to tasking.c.
4102 * parse.y (rccase_label): Move most of the logic to
4103 build_receive_case_label in tasking.c.
4104 * parse.y (sendaction): Re-write to not depend on SIGNALNAME.
4106 * parse.y (name): Do name lookup here (and not in location).
4107 * parse.y: Replace most uses of NAME by higher-level non-terminals:
4108 simple_name_string, name_string, defining_occurrence, or name.
4110 * tasking.c (build_receive_signal_case_label,
4111 build_receive_buffer_case_label): New functions, split out from
4112 build_receive_case_label.
4113 * tasking.c (build_receive_case_label): Change parameters
4114 and return type. Moved stuff here (from the parser).
4115 * tasking.c (struct rc_state_type): Removed had_errors.
4116 Return error_mark_node instead.
4117 * tasking.c (build_rccase_set_error), ch-tree.h: Removed.
4119 * expr.c (build_generalized_call): If func is a signal type,
4120 call build_signal_descriptor.
4122 * parse.y (arrayindex): Renamed to index_mode, to match Z.200.
4123 * parse.y (ioindexmode): Removed; use index_mode instead.
4124 * expr.c (build_generalized_call): If args is a RANGE_EXPR,
4125 we have either a slice or a range mode, depending on func.
4126 * parse.y (index_mode): If we got an 'expr', only allow a name,
4128 * parse.y (call): A slice with both end points can be a range
4129 mode, so defer handling to build_generalized_call (or index_mode).
4131 * typeck.c (build_chill_slice_with_length): Fix type-checking.
4132 * typeck.c (chill_novelty): Undo (part of) change of April 28:
4133 The novelty of a range mode is the novlety of the parent.
4134 * typeck.c (chill_root_mode): Don't return integer_type_node
4135 if argument has non-nil novelty.
4137 * decl.c (global_bindings_p): Return -1 as true, for the sake
4138 of variable_size (in ../stor-layout.c).
4140 Fri Apr 29 13:42:43 1994 Per Bothner (bothner@kalessin.cygnus.com)
4142 * parse.y: Remove TYPENAME and modename. These are now plain
4143 NAMEs. Modify parsing actions appropriately.
4144 * expr.c (build_generalized_call): Handle the case that
4145 TREE_CODE (func) == TYPE_DECL (as in a cast).
4146 * lex.l (name_type_signal): Never return TYPENAME.
4147 * parse.y (get_type_of): If pass 1, just return the argument.
4149 * decl.c (do_decl): If an initializer has the wrong type,
4150 replace it by NULL_TREE, to avoid subsequent errors.
4152 Thu Apr 28 15:21:56 1994 Wilfried Moser (moser@rtl.cygnus.com)

4192 ch-tree: New functions.
4194 Thu Apr 28 14:11:29 1994 Per Bothner (bothner@kalessin.cygnus.com)
4196 * typeck.c (smash_dummy_type): Handle the special case of a
4197 NEWMODE of a range mode, as required by Z200, by creating a
4198 new parent mode with the new novelty (and casting the min
4199 and max of the range to teh new parent mode).
4200 * typeck.c (chill_novelty, chill_root_mode): Remove special
4201 kludges for of NEWMODE ranges.
4202 * expr.c (build_chill_lower_or_upper): New function, combining
4203 the "guts" of build_chill_lower and build_chill_upper.
4204 * expr.c (build_chill_lower_or_upper): Simplify; no longer
4205 need to kludge the novelties.
4207 * typeck.c (valid_array_index_p): A string index expression
4208 need not be Compatible with the index type; only similar.
4210 * decl.c (layout_chill_variants): If error seen, skip stuff
4211 (rather than aborting or crashing).
4212 * decl (push_modedef): If newdecl's type is an error mark,
4213 continue rather than aborting.
4215 Thu Apr 28 02:07:42 1994 Doug Evans (dje@cygnus.com)
4217 * Make-lang.in: Update of directory reorg from fsf.
4218 * config-lang.in: Ditto.

4222 * typeck.c (chill_similar): Check RECORD_TYPEs properly,
4223 * convert.c (convert): If all else fails, just call convert1.
4224 Thus we can now convert RECORD_TYPEs (assuming they are similar).
4226 * parse.y, lex.l: Remove BUFFERNAME (use location/expr instead).
4227 * parse.y: Re-do BUFFER handling (similar to previous EVENT change).

4235 to name and simple_name_string. This removes a reduce/reduce conflict.
4236 * Makefile.in (stamp-parse): Expect fewer conlicts.
4238 * lex.l (yywrap): Move check for circularly seizeing current
4239 grant-file from here ...
4240 * lex.l (handle_use_seizefile_directive): ... to here.
4241 This is to avoid calling stat on a not-yet written grantfile,
4242 now that we're using same_file (which calls stat).
4243 * grant.c (set_use_this_gf): Removed.
4244 * grant.c (set_default_grant_file): Set grant_file_name here,
4245 because we need it earlier (due to above lexer change).
4247 * typeck.c (layout_chill_struct_type): Remove useless code to
4248 remove zero-width bitfield (which messes up CONST_DECLs).
4250 Sat Apr 23 13:16:39 1994 Bill Cox (bill@rtl.cygnus.com)
4252 * Makefile.in (check): Assure that 'ld' is available before checking.

4293 * Makefile.in (check): Simplified regression.sh call.
4294 * regression.sh: Change command-line parsing. Default
4295 srcdir to the script's path. Calculate objdir
4296 internally - don't pass it in.

4320 * lex.l (chill_same_grant_file): Rename to same_file. Change to
4321 take two files names rather than two DECLs. Also check that the
4322 filesystems (st_dev) are equal. Finally, make static.

4324 USE_SEIZE_FILE directives using same_file.
4325 * decl.c (pop_module): Remove dubious call to chill_same_grant_file.

4341 * actions.c (chill_expand_assignment): Check for compatibility
4342 _after_ "expanding out" a binary operation. This fixes
4343 the case "STRING //:= CHAR".
4345 * lex.l (equal_number): Convert symbol to integer_type_node, to
4346 force the value to be INT-derived (and avoid novelty conflicts).

4450 * typeck.c (build_chill_modify_expr): Simplify.
4452 Sun Mar 27 19:30:25 1994 Bill Cox (bill@rtl.cygnus.com)
4454 * Makefile.in: Clean up generally. Assure that
4455 runtime is built before running regressions.

4486 Wed Mar 23 13:34:18 1994 Bill Cox (bill@rtl.cygnus.com)
4488 * expr.c (build_generalized_call): Revert previous change.
4489 To do this correctly, we need a new parsing mechanism, and

4511 * configure: Generate better .gdbinit files.
4513 Tue Mar 22 11:59:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
4515 * actions.c (check_range): Don't emit dynamic checks
4516 if not current_function_decl.
4518 * parse.y (arrayindex): Allow expr (error is emitted
4519 at semantic level if not the NAME of a type).
4520 * typeck.c (build_chill_cast): Re-enable some casts.
4521 * satisfy.c (safe_satisfy_decl): Remove redundant CONST check.

4538 string assignment case.
4539 * expr.c (chill_expand_expr): Now that we're using build_chill_function_call,

4541 type explicitly. Do that.
4542 * satisfy.c (safe_satisfy_decl): Correct range-checking code.
4544 Mon Mar 21 16:25:07 1994 Bill Cox (bill@rtl.cygnus.com)

4554 * typeck.c (layout_chill_range_type): Instead of tree_int_cst_lt
4555 use compare_int_csts (which is more robust when signedness differs).

4559 * expr.c (chill_expand_expr): Code to expand SET_IN_EXPR,
4560 moved from expand_expr in ../expr.c. Also add some extra
4561 conversions (because we're now using build_chill_function-call).
4562 * actions.c, decl.c, expr.c, grant.c, parse.y, typeck.c:
4563 Use SET_IN_EXPR in place of IN_EXPR.
4565 * expr.c (build_compare_discrete_expr), ch-tree.h: New function,
4566 with code moved from build_compare_expr.
4567 * expr.c (build_compare_expr): Re-enable compatibility test.

4594 to be compatible with the N-value class, with suitable M and N.
4595 * typeck.c (build_chill_slice): Don't smash a void TREE_TYPE.

4598 * expr.c (build_compare_expr): Fix thinko. Add save_exprs.
4600 * expr.c (build_compare_expr): Fix a transcription bug
4601 (for converting NULL INSTANCEs). Also #include convert.h.

4605 * expr.c (finish_chill_binary_op): Moved code dealing with
4606 the comparison operators from here ...
4607 * expr.c (build_compare_expr): ... to new function here.

4612 * typeck.c (valid_array_index_p): Various cleanups,
4613 including using new build_parse_expr.

4632 to have consistent operand types.
4633 * typeck.c (valid_array_index_p): Change interface to pass
4634 validity conditions back on caller's TREE_LIST. We
4635 cannot link the conditions to anything which a
4636 layout_type routine will expand, since that will occur
4637 before the exception handler is set up.
4638 Change calls to valid_array_index_p also.
4640 Fri Mar 18 14:40:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
4642 * actions.c, except.c, loop.c, tasking.c: Call

4645 * except.c (initialize_exceptions): Fix parmtype of __builtin_setjmp.
4646 * loop.c (top_loop_end_check): Coerce library function arg.
4647 * convert.c, expr.c: Re-write to avoid calls to C-specific
4648 function build_unary_op (e.g. by calling build1 directly).
4650 * typeck.c (chill_equivalent): Change to force failure
4651 for non-matching integral types (even if not ranges).
4653 * typeck.c, ch-tree.h (build_chill_slice): Make non-static.
4654 * expr.c (varying_to_slice): Call build_chill_slice (and not
4655 build_chill_slice_with_length, which does bunches of range
4656 checking and does not allow the length to be zero).
4657 * convert.c (convert): Fix off-by-one error.
4658 * actions.c (chill_expand_array_assignment): Minor cleaning up.
4660 Fri Mar 18 00:12:48 1994 Per Bothner (bothner@deneb.cygnus.com)

4663 take *two* pointer parameters, not one.
4664 * satisfy.c (satisfy): Only call the appropriate layout routine
4665 if TYPE_SIZE is 0 (i.e. type hasn't already been laid out).
4666 * typeck.c (build_chill_slice_with_length): Fix Bill's previous fix.

4677 * typeck.c (build_chill_slice), expr.c (chill_expand_expr
4678 [case CONCAT_EXPR]): Remove kludge setting slice size upper bound
4679 in TYPE_LANG_SPECIFIC, and restore kludge setting it in MAX_VALUE.
4680 * typeck.c (build_chill_slice): Use TYPE_MAX_VALUE of
4681 array_type if needed for size upper bound of slice_type.
4682 * expr.c (build_concat_expr): Improve calculation of size upper bound.
4684 * typeck.c (valid_array_index_p): Check compatibility using
4686 * typeck.c (build_chill_slice_with_length); For now revert
4687 calling valid_array_index_p on length. (It makes it harder
4688 to realize when the slice is constant length.)
4689 * expr.c (build_chill_indirect_expr): Minor tweak. (This
4690 seems to work around a weird C compiler bug. ??)
4692 * expr.c (build_chill_function_call): Cleanup so it doesn't
4693 call build_function_call (in c-typeck.c).
4694 * typeck.c, expr.c: Use build_chill_function_call instead of
4695 build_function_call (in c-typeck.c).
4697 * parse.y (discrete_mode): Move some of the rules from
4698 non_array_mode into new non-terminal.
4699 (arrayindex): Use discrete_mode (with NAME and TYPENAME) to
4700 avoid some misparses.
4701 * ch-tree.h (SLICE_PTR, SLICE_LENGTH): Removed; unused.
4702 * convert.c (digest_structure_tuple): Add missing parameter.
4703 * decl.c (comptypes): Remove unused prototype.
4704 * decl.c (build_chill_function_type): Handle NULL return_type
4705 correctly (convert to void_type_node).
4706 * decl.c (init_decl_processing): layout boolean_type_node *after*
4707 we've set it's TYPE_MIN_VALUE and TYPE_MAX_VALUE.
4709 Wed Mar 16 16:08:22 1994 Bill Cox (bill@rtl.cygnus.com)

4712 * convert.c (convert): Correct calculation of padding length.
4713 * decl.c (grok_chill_fixedfields): Move ignore_exprs test to
4714 parse.y where it belongs. This permits the removal of a kludge
4715 in make_process_struct.

4717 code to output error in only one pass.

4726 (expand_varying_length_assignment): call valid_array_index_p.
4727 rather than validate_varying_array_ref.
4728 * ch-tree.h: Fix prototype for valid_array_index_p.
4729 * expr.c (chill_expand_expr): Call build_chill_array_ref to get
4731 (build_hill_lower, build_chill_upper): Return value now inherits
4732 the novelty of the input parameter.
4733 (varying_to_slice): Use CH_NOVELTY macro rather than calling
4734 chill_novelty directly.
4735 * grant.c (newstring): Make len unsigned and cast xmalloc parameter
4737 (print_integer_type): Pass string value as APPEND's second parameter.
4738 (decode_decl): Pass a boolean expression as print_proc_tail's
4740 (chill_finish_module_code): Make xmalloc's parameter unsigned.
4741 * lex.l: Pass sizes to xmalloc as unsigned ints. Pass second
4742 parameter to in_word_set as unsigned.
4743 * loop.c (build_loop_start): Check top_loop_end_check return value.
4744 * parse.y: Add casts to int for third do_decls parameter, fifth
4745 build_loop_iterator parameter, etc.
4746 * tasking.c (build_receive_case_end): Chack cond_stack before popping.
4747 * typeck.c (validate_varying_array_ref, chill_max_vary_array_index,
4748 valid_array_index): Delete them. They're now unused.
4749 (valid_array_index_p): Add function, call it everywhere that an
4750 array index is checked.
4751 (build_chill_slice): Restore old functionality where varying_to_slice
4752 is called to handle slices of varying arrays, rather than handling
4754 (build_chill_slice_with_range, build_chill_slice_with_length):
4755 Check range limits for TREE_CONST before calling tree_int_cst_lt.
4756 Delete now-obsolete checks of constant indices.
4758 Mon Mar 14 17:26:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4760 * parse.y (modeless_expr): New rule to allow ([...]) and (if...)
4761 to count as untyped_exprs. (This is not really permitted by the
4762 Blue Book, but has been requested by customers.)
4764 Thu Mar 10 10:11:02 1994 Bill Cox (bill@rtl.cygnus.com)
4766 * chill.texi: Document new command-line options.

4775 * Makefile.in: Have rules to make parse.h, y.tab.c and other
4776 derived files. This allows the gcc/configure list of CHILL
4777 files machinery to work.
4778 * ch-tree.h (permanent_allocation): Add a parameter flag.
4779 * decl.c (finish_chill_function, finish_decl): Provide the
4780 new permanent_allocation flag.
4781 (poplevel): Return early, avoid a seg fault.
4782 * lex.l (NORMAL): Replace this whole state with the predefined
4783 INITIAL state. Force compilation state to global level after
4784 compiler directive error - prevents endless loop on error.
4785 (handle_use_seizefile_directive): Rewrite for readability.
4786 (chill_same_grant_file): Reindent.
4787 Generally handle whitespace differently.
4788 * regression.prpt: Print ten PR numbers per line. The report's
4791 Wed Mar 9 09:58:51 1994 Bill Cox (bill@rtl.cygnus.com)
4793 * decl.c (do_decl): Suppress the string-assignment-condition
4794 error - it was too often seen.
4795 * expr.c (expand_chill_expr): In CONCAT_EXPR, when argument has a
4796 runtime-changing length (as in a slice), get the parent array's
4797 allocation size from its type tree.
4798 * typeck.c (build_chill_slice): Support VARYING arrays. Pass
4799 parent array's static allocation size along in the slice type.

4968 Wed Feb 23 15:07:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4970 New cleaner solution to the following problem:
4971 Chill allows an action to be followed by an ON-handler.
4972 But we don't know if an action has a handler until we've parsed
4973 its end, yet we want to generate extra code to set up an
4974 exception handling contour only if needed. The old solution
4975 would generate code for the action into an rtl sequence, and then
4976 splice in the exception-setup code if we later found we needed it.
4977 This has a few problems (for example it confuses the management
4978 of stack temporaries), and is ugly. Now that the compiler is 2-pass
4979 we have a cleaner solution: In pass 1, we remember which actions
4980 were followed by ON-handlers. In pass 2, we use this information
4981 to generate appropriate code before an action.
4982 * except.c (push_handler, pop_handler): In pass 1, set up data
4983 structures (global_handler_list) to remember if an action has an
4984 ON-handler. In pass 2, digest this information, and setup
4986 * except.c, actions.h (pop_handler): Take an extra int arg.
4987 * except.c (emit_setup_handler): New function, with code (moved
4988 from chill_start_on) to emit code before an action that has a handler.
4989 * except.c (except_init_pass_2): New function.
4990 * parse.y (pass1_2): Call except_init_pass_2 before pass 2.
4991 * parse.y (POP_UNUSED_ON_CONTEXT): Don't call pop_sequence.
4992 * parse.y: Invoke POP_UNUSED_ON_CONTEXT and POP_USED_ON_CONTEXT
4993 in pass 1 as well as pass 2.
4994 * parse.y (BEGIN ... END): Re-arrange logic to avoid block_stack
4995 (local to ../stmt.c) getting out of sync.
4996 * actions.c (push_action): Don't need to emit a NOP,
4997 now that we're no longer moving sequences around.
4998 * actions.c (push_action): Call push_handler even in pass one.

5772 about when to generate rangecheck code.
5773 * ch-expr.c (build_chill_function_call): Sketch in where to
5774 perform chill_convert_for_assignment on actual parameters.
5775 (build_chill_addr_expr): Correct compiler warning.
5776 * ch-loop.c (build_chill_iterator): Add runtime check for
5777 negative loop step expression.
5778 * ch-tree.h: Add prototype.
5779 * ch-typeck.c (chill_max_vary_array_ref): Correct misunderstanding.
5780 A varying array's length field counts the NUMBER of active array
5781 array entries, not the byte-length of them.
5783 Tue Jan 4 17:57:39 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5785 * ch-decl.c (do_decl): Call `suspend_momenary' if the
5786 converted constructor must live on the permanent_obstack.
5787 * ch-convert.c (convert): When building a new SET_TYPE
5788 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5789 * c-typeck.c (chill_initializer_constant_valid_p): Handle VAR_DECLs.
5791 * ch-typeck.c (chill_location): CONSTRUCTORS that are static
5793 * ch-satisfy.c (safe_satisfy_decl): Convert DECL_INITIAL of CONST_DECL
5794 on permanent_obstack if necessary.
5796 * ch-convert.c (digest_structure_tuple): When building a new SET_TYPE
5797 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5799 * ch-decl.c (do_decl): Fix handling of REFERENCE_TYPEs which
5800 the patch below helped to mess up.
5802 * ch-expr.c (build_chill_arrow_expr): Call `mark_addressable'.
5803 (build_chill_addr_expr): Take new argument ERRORMSG.
5804 All callers changed. Also, call `build_chill_addr_expr' where
5805 we used to call `build1 (ADDR_EXPR, ptr_type_node, ...)' since
5806 that now calls `mark_addressable' automagically.
5808 * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.
5809 This is needed because variables may appear in initialization
5810 statements, and their DECL_INITIALs are their values at
5811 initialization time.
5812 * ch-convert.c (digest_structure_tuple,digest_constructor): Changed
5813 to handle VAR_DECLs as initializers.
5815 * ch-convert.c (digest_structure_tuple): Copy elements of INITS so
5816 they aren't destroyed for later use.
5818 Tue Jan 4 15:25:30 1994 Bill Cox (bill@cygnus.com)
5820 * ch-expr.c (chill_expand_expr): Correct check-range lo_limit
5821 parameter for varying_array_ref calculations.
5822 (build_chill_indirect_ref): Prevent seg fault due to syntax error.
5823 * ch-typeck.c (build_chill_slice_with_range): Correct issuance
5824 of bogus error in votrics.
5825 (build_chill_slice_with_length): Change for debug tracability.
5827 Tue Jan 4 02:43:37 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5829 * ch-convert.c (digest_structure_tuple): Fix phasing problem in
5830 handling variant record initializers.
5831 (various places): Change `pop_init_level' calls to match
5832 `push_init_level' wrt implicit variable.
5834 * ch-typeck.c (build_chill_slice): Convert the dynamic max index to
5835 `integer_type_node' before using it in comparisons. FIXME: should
5836 this be done in `chill_max_vary_array_index' by default?
5838 Tue Jan 4 00:24:14 1994 Bill Cox (bill@cygnus.com)
5840 * ch-actions.c: Fix comments.
5841 * ch-parse.y: Define caseaction_flag.
5842 (caseaction): Create new caseaction_flag node at the start,
5843 then free it at the end. Check it before the ELSE code.
5844 (expanded_case_label): Check the flag here. If set in either
5845 place, generate a jump to the end of the case.
5846 * ch-typeck.c (build_chill_slice_with_length,
5847 build_chill_slice_with_range): Add lots of compile-time
5848 parameter range checking.
5850 Mon Jan 3 21:49:04 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5852 * ch-convert.c (digest_structure_tuple): Call `push_init_level' with
5853 implicit==0 everywhere, not 1.
5854 (digest_constructor): Ditto.
5856 * ch-actions.c (check_range): Permit limits to be NULL_TREE.
5857 Also, hack out some dead code.
5858 * ch-typeck.c (build_chill_slice): Check varying and non-varying
5859 slice constructs for range failures.
5860 (build_chill_slice_with_range): Reindented, but not changed.
5862 * ch-typeck.c (chill_max_vary_array_index): New function.
5863 * ch-expr.c (chill_expand_expr): Call it.
5865 * ch-decl.c (var_data_id, var_length_id): New variables.
5866 (init_decl_processing): Initialize them. All calls to
5867 get_identifier (VAR_LENGTH or VAR_DATA) are now replaced
5868 by references to these variables. This simplifies the code
5869 w/o obscuring anything.
5871 Mon Jan 3 21:24:44 1994 Bill Cox (bill@cygnus.com)
5873 * c-typeck.c: Fix comment.
5874 * ch-actions.c (chill_expand_assignment): Error assigning to
5875 READONLY location. (PR_3903) Pass filename, linenumber
5876 to setbitpowerset runtime routine.
5877 * ch-decl.c (init_decl_processing): Add filename, linenumber
5878 parameters to setbitpowerset prototype.
5879 * ch-expr.c (build_chill_function_call): Error when passing a
5880 READonly location as a LOC or INOUT parameter.
5881 * ch-parse.y (mode): Correct code marking type as readonly.
5883 Mon Jan 3 19:03:55 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5885 * ch-actions.c (chill_expand_assignment): Disable code that defeats
5886 building varying array references.
5887 * ch-expr.c (chill_expand_expr): Add rangecheck code to
5888 VARY_ARRAY_REF case.
5889 * ch-typeck.c (build_chill_array_ref): Don't call an `expand_'
5890 function (in this case, `validate_varying_array_ref') when we're
5891 doing a `build_' operation.
5893 * ch-typeck.c (validate_varying_array_ref): Simplify interface
5894 since INDEX parameter can never meaningfully be an INDEXLIST.
5895 * ch-actions.c (expand_varying_length_assignment): Caller changed.
5897 Mon Jan 3 07:29:45 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5899 * ch-typeck.c (build_chill_cast): Set TREE_CONSTANT on NOP_EXPRs.
5900 * ch-convert.c (digest_structure_tuple): Switch to permanent_obstack
5901 if we need to build a CONSTRUCTOR for a SET_TYPE initializer.
5902 (digest_structure_tuple): If TREE_VALUE (VALUE) == NULL_TREE, don't
5903 call CH_COMPATIBLE or try to convert it to TREE_TYPE (FIELD). This
5904 can happen when constructors are output incrementally.
5905 * c-typeck.c (initializer_constant_valid_p): Handle SET_TYPEs.
5906 * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
5909 Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5911 * ch-convert (digest_structure_tuple): Handle SET_TYPEs. Also, call
5912 `convert' so we can handle INSTANCE types (and other anomolies)
5915 * ch-convert.c (digest_structure_tuple): Fixed variant
5916 structure initialization. Also fixed a typo (TYPE_NAME
5917 was being used on a FIELD_DECL instead of DECL_NAME).
5918 * c-typeck.c (initializer_constant_valid_p): Pass missing
5919 ENDTYPE argument on recursive call.
5920 (set_init_field): New function, needed by ch-convert.c change above.
5922 * ch-decl.c (layout_chill_variants): Added a FIXME next to an
5923 almost certain typo.
5925 * ch-expr.c (build_chill_arrow_expr): Call `build1' and set
5926 TREE_CONSTANT for static references.
5927 * ch-except.c (chill_start_on): Change calls to
5928 `build_unary_op' (which is C-specific) to `build_chill_arrow_expr'
5929 which has CHILL semantics.
5930 * ch-convert.c (convert): Ditto (albeit in some disabled code).
5932 Sat Jan 1 21:26:43 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5934 * ch-satisfy.c (safe_satisfy_decl): Reorder conditional test of
5935 TREE_CODE of DECL in case it's altered by actions in the switch.
5937 * ch-satisfy.c (satisfy): Undo abort added earlier on 1 Jan. CVS log
5938 mentions where to find code that triggers this case.
5940 * ch-actions.c (adjust_parm_or_field): Handle CONSTRUCTORS here as
5943 * ch-convert.c (digest_structure_tuple): Push to permanent_obstack if
5944 we're dealing with a CONSTRUCTOR that is TREE_PERMANENT.
5945 (digest_constructor): Ditto.
5947 Sat Jan 1 10:29:19 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5949 * ch-parse.y (handleraction,resultaction,assignaction,call): Modified
5950 so that CONSTRUCTORS are properly handled before being used.
5952 * ch-convert.c (chill_start_init): New function. All callers to
5953 `start_init' changed to call this function instead.
5954 (digest_struct_tuple): Defend against initialization machinery
5955 mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
5956 IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
5957 needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
5958 can be refered to throughout the compilation unit. Also remove an
5959 extraneous call to `process_init_element' erroneously added to the
5960 variant record sub-loop.
5961 (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
5962 CONSTRUCTORS of SET_TYPE.
5963 * ch-parse.y (build_chill_constructor): Refix typo. Also set
5964 TREE_STATIC if at top level.
5966 * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
5967 TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
5968 should have been called.
5970 * ch-convert.c (digest_struct_tuple): Restore code which tracks
5971 field initializations so that the compiler can deduce what variant
5972 initializations to assume.
5974 * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
5975 when we push into a scope that has a DECL with a CONSTRUCTOR as its
5978 * ch-parse.y (build_chill_constructor): Change the name of the
5979 parameter to something more meaningful. Fix typo. Also, handle case
5980 where element is an untyped CONSTRUCTOR.
5982 * ch-except.c (finish_handler_array): Set TREE_CONSTANT on
5983 constant ADDR_EXPRs.
5984 (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT
5985 on JBUF_REF (instead of calling `build1' which does not).
5987 * ch-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
5989 * ch-typeck.c (chill_expand_tuple): Deleted.
5990 * ch-parse.y (primval rule): Don't call `chill_expand_tuple';
5991 instead, use initialization machinery for CONSTRUCTORS that
5993 * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
5994 that are created here.
5995 * ch-satisfy (satisfy): Abort in case we would have called
5996 chill_expand_tuple. FIXME: some other code is needed here,
5997 but I don't know what yet.
5999 * ch-parse.y (build_chill_constructor): New function to
6000 propagate TREE_CONSTANT bits to CONSTRUCTORS.
6001 (untyped_expr rule): Use it.
6002 (primval rule): Use it.
6004 * ch-decl.c (do_decl): Call `finish_init'.
6005 * ch-convert.c (convert): If we spontaneously create a CONSTRUCTOR in
6006 this function, make sure the initialization machinery is set up.
6008 * ch-convert.c (digest_structure_tuple, digest_constructor): Add
6011 Fri Dec 31 11:31:01 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6013 * ch-grant.c (chill_finish_module_code): Mark ADDR_EXPR built by hand
6014 as being TREE_CONSTANT. Otherwise it gets bounded by the initializer
6017 * ch-decl.c (do_decl): Change in CONSTRUCTOR handling due to...
6018 * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
6019 rewritten to work with GCC's initialization code. The basic change
6020 was to keep the initializers in sync with the initialization
6021 machinery that `process_init_element' imposes. Both of these
6022 functions now return `void'.
6023 * ch-convert.c (convert): Changed calls to `digest_...' functions.
6025 FIXME: the code handling UNION_TYPE (and variant records) has not
6028 Fri Dec 31 15:32:56 1993 Bill Cox (bill@rtl.cygnus.com)
6030 * ch-lex.l (convert_number): Output the converted number if
6032 * ch-parse.y (signaldef): Set ignore_exprs correctly for a
6035 Fri Dec 31 13:17:48 1993 Bill Cox (bill@cygnus.com)
6037 * ch-parse.y: Cleanup handling of RETURN actions, to distinguish
6038 a RETURN without a value (which cannot have an exception
6039 handler) from a RETURN with a value (which can). Eliminate
6040 some shift/reduce and reduce/reduce conflicts.
6042 Thu Dec 30 17:42:32 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6044 * ch-inout.c (build_chill_writetext): Deal with 2 cases where
6045 types returned from `type_for_size' are not expected. FIXME.
6046 * ch-decl.c (init_decl_processing): Mark `char_type_node' unsigned.
6047 This is required when range checking is enabled.
6049 Thu Dec 30 14:28:25 1993 Bill Cox (bill@rtl.cygnus.com)
6051 DELAY CASE works now.
6052 * ch-decl.c (init_decl_processing): Move rest of tasking-related
6053 initialization into tasking_init().
6054 * ch-parse.y (delaycaseaction): Pervasive additions/corrections.
6055 (optsetprio): New non-terminal.
6056 * ch-tasking.c (get_task_name): Delete, obsolete.
6057 (build_instance_type): build pointer to instance type also.
6058 (build_receive_case_start): Cleanup per -Wall messages.
6059 (build_receive_case_label): Move between start and end functions.
6060 (build_delay_case_start): Pass SET name and priority also.
6061 Generally update to correct functioning.
6062 (build_delay_case_label): Move between start and end fucntions,
6063 correct its functioning.
6064 (build_delay_case_end): Correct the code.
6065 (tasking_init): Lots of tasking-related code moved here from
6066 init_decl_processing.
6067 * ch-tree.h: Update, add prototypes.
6069 Wed Dec 29 10:13:10 1993 Bill Cox (bill@rtl.cygnus.com)
6071 * ch-expr.c (build_chill_indirect_ref): Revert change which
6072 failed full regression testing.
6073 * ch-lex.l (name_type_signal): Add debug output.
6074 * ch-parse.y (structured_variable): Add a debug variable.
6076 Wed Dec 29 02:05:51 1993 Bill Cox (bill@rtl.cygnus.com)
6078 * ch-decl.c (get_next_decl): Revert change which failed full
6081 Tue Dec 28 18:20:14 1993 Bill Cox (bill@rtl.cygnus.com)
6083 DELAY actions work now.
6084 * ch-decl.c: Correct spelling in comments.
6085 (get_next_decl): NULL out the decl's TREE_CHAIN before returning
6086 it, to prevent accidental access to the remembered_decls.
6087 (init_decl_processing): Add wait_event to runtime functions.
6088 * ch-expr.c (build_chill_indirect_ref): Prevent a syntax error from
6089 becoming a seg fault.
6090 * ch-grant.c: Correct a comment.
6091 * ch-loop.c: Delete/correct comments.
6092 * ch-parse.y (delaycaseaction): Add push/poplevel calls. Turn 'sorry'
6093 into rough draft of actual code.
6094 (delayaction): Don't make a new scope here, use get_unique_identifier
6096 (locdec): process event decls here, too.
6097 (mode): Add code to forbid READonly EVENT and BUFFER decls. Delete
6098 code which required EVENTs and BUFFERs to be declared at global scope.
6099 (simple_name_string): Add an EVENTNAME.
6100 * ch-satisfy.c (safe_satisfy_decl): Prevent a syntax error from
6101 becoming a seg fault.
6102 * ch-tasking.c (tasking_setup): Add the event queue's max. length
6103 as the 'entry_point' parameter in the list.
6104 (build_receive_case_start, build_receive_case_label): Defer
6105 calling runtime routine until we know whether we have a signal
6106 or a buffer to wait for.
6107 (build_delay_case_start, build_delay_case_end,
6108 build_delay_case_label, build_delay_action,
6109 process_event_decls): Added functions.
6110 * ch-typeck.c (chill_similar): Allow all integers of differing
6111 precisions to be similar.
6113 Thu Dec 23 18:00:40 1993 Bill Cox (bill@rtl.cygnus.com)
6115 * gcc.c (CHILL SPECS): Delete references to -M -MM -MD -MMD
6116 options. Delete C-specific defines. Disable piping from
6117 pre-processor to cc1chill (even if -pipe is specified), since cc1chill
6118 rewinds its input for its second pass. Piping still works
6119 from cc1chill to as.
6121 Thu Dec 23 12:31:55 1993 Bill Cox (bill@rtl.cygnus.com)
6123 * ch-tasking.c (decl_tasking_code_variable): Assure that the
6124 tasking_code variable is allocated on the permanent obstack.
6125 (tasking_setup): Lots of changes - handle EVENT/BUFFER max.
6126 queue length (passed as the entry_point parameter).
6127 Other changes to variable names to increase 'self-documentation'
6128 the only kind GNU CHILL will get, for a while..
6130 Wed Dec 22 10:46:31 1993 Bill Cox (bill@rtl.cygnus.com)
6132 * ch-decl.c (do_seize): Delete - it's unused. Fix comments.
6133 * ch-loop.c (build_chill_iterator): Convert BY expression
6134 so loop involving a SET works. Additional errors generated
6135 for numbered SET expression as start or end expression.
6136 * ch-tree.h: Prototypes for future DELAY functions.
6137 * ch-typeck.c: Standard indentation.
6139 Tue Dec 21 15:30:57 1993 Per Bothner (bothner@kalessin.cygnus.com)
6141 * ch-actions.c (build_cause_exception): New function.

6149 * ch-lex.l (init_lex): Use new macro to make more terse.
6150 * ch-typeck.c (chill_equivalent): New function.
6151 Also check that ranges have the same bounds.
6152 * ch-typeck.c (my_build_array_ref): Add optional range-checking.
6153 * ch-typeck.c (chill_location): Handle COMPOUND_EXPR properly.
6154 Return 2 if also a referable.
6155 * ch-typeck.c (chill_referable): Re-define to use chill_location.
6156 * ch-tree.h (CH_EQUIVALENT): Re-defined to use chill_equivalent.
6158 * dbxout.c (dbxout_type): Output the type attribute "@S;" to
6159 distinguish a string from a char array, and to distinguish a
6160 bitstring from regulat (power)set. (Needed for Chill.)
6161 * dbxout.c (dbxout_type): Only check for baseclasses in
6162 type.binfo is a vector. (It is used in Chill for tagged unions.)
6164 Fri Dec 17 09:56:07 1993 Bill Cox (bill@rtl.cygnus.com)
6166 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
6167 ch-grant.c, ch-inout.c, ch-loop.c, ch-parse.y,
6168 ch-satisfy.c, ch-tasking.c, ch-tree.h, ch-typeck.c:
6170 * ch-actions.c (chill_expand_assignment): Error if assigning
6171 a value to a BUFFER or EVENT variable.
6172 * ch-expr.c (invalid_left_operand): Delete, unused.
6173 * ch-grant.c (tasking_setup): Call build_enum_tables.
6174 * ch-inout.c (get_final_type_and_range, build_enum_tables,):
6176 (build_chill_writetext): Lots of changes to support other
6177 basic CHILL data types.
6178 * ch-loop.c (build_chill_iterator): Lots of new code to check
6179 the expressions in a STEP loop.
6180 * ch-tasking.c (rc_state): Add fields to flag SIGNAL and BUFFER
6181 names in receivecasealternative. Generate error messages
6182 if they're mixed in the same receive case.
6183 (process_buffer_decl): Renamed from build_buffer_decl.
6184 * ch-tree.h: Fix prototypes.
6185 * ch-typeck.c (smash_dummy_type): Handle all four kinds of LANG_TYPE
6186 correctly. Thanks Per!
6188 Wed Dec 15 15:05:56 1993 Per Bothner (bothner@kalessin.cygnus.com)
6190 * ch-decl.c (push_scope_decls): Re-arrange some more, so
6191 that normal SEIZES (without ALL) are handled before SEIZE ALL.
6193 Wed Dec 15 13:01:22 1993 Bill Cox (bill@rtl.cygnus.com)
6195 * ch-loop.c (declare_temps): Calculate end-of-array pointer
6196 using correct type (NOT chill_integer_type).
6197 (begin_chill_loop): Build loop-bypass expression in the
6198 type of the start expression, not in the unsigned type.
6200 Tue Dec 14 15:41:32 1993 Per Bothner (bothner@kalessin.cygnus.com)
6202 * ch-decl.c (push_scope_decls): Re-arrange so that normal
6203 (non-seize) declarations are proclaim_decl'd *before* we
6204 handle the ALIAS_DECLs for seizes. The advantage is
6205 that we can now test for (an approximation) to the
6206 'seizeable' concept, thus avoiding duplicate definitions
6207 when a module has both GRANTs and SEIZE ALL.
6209 * ch-expr.c (build_chill_arrow_expr): No longer re-write
6210 addr-of-conversion to pointer-conversion-of-addr.
6211 * ch-expr.c (build_chill_addr_expr): Re-write to just use
6212 build_chill_arrow_expr.
6214 Mon Dec 13 16:44:43 1993 Per Bothner (bothner@kalessin.cygnus.com)
6216 * ch-expr.c (build_chill_addr_expr, build_chill_addr_expr): Don't re-write
6218 * ch-tree.h (chill_root_resulting_mode): Fix typo (missing '_').
6220 * ch-expr.c (finish_chill_binary_op): Use CH_ROOT_RESULTING_MODE
6221 macro (which works on expressions), rather than CH_RESULTING_MODE
6222 (which works on modes, and isn't quite correct).
6223 * ch-tree.h (CH_IS_BOUND_REFERENCE_MODE): New macro.
6224 * ch-typeck.c (chill_read_compatible, chill_compatible):
6225 Use the new macro, which handles NEWMODEs of PTR correctly.

6959 specify a value for each of them.
6960 * ch-parse.y (check_end_label, action, exceptlist): Only output
6961 error message in pass 1.
6962 (sendaction): Add comments.

6970 parameter to know whether to include an init expression.
6971 (build_process_header): Attach tasking-code_variable to process
6972 function_decl for easy access later, not through the hash table.

6987 generation for decls to not use DECL_ASSEMBLER_NAME.
6988 * ch-decl.c: Set DECL_ASSEMBLER_NAME to DECL_NAME.
6989 This matches C, and allows dbxout to emit proper user-level names.

7014 not error_mark_node.
7015 * ch-actions.c (chill_expand_assignment): Allow such borderline

7176 * ch-expr.c (chill_expand_case_expr): Add parameter
7178 * ch-grant.c (chill_finish_compile): Add code to spoof
7179 get_file_function_name, so we don't get __tmp_s1_code,
7180 for example, as the module-level code's name.
7181 * ch-loop.c (build_temporary_variable, begin_for_range,
7182 init_loop_counter): Add parameter to decl_temp1 call.
7183 * ch-parse.y (quasi_signaldef): Clear quasi_signal flag here,
7184 for easier maintenance.

7190 (build_start_process): Add parameter to decl_temp1 call.
7191 (tasking_setup): Comment out band-aid hack which calls
7192 generate_tasking_code_variable. Shouldn't be necessary.

7230 Mon Oct 4 15:43:56 1993 Per Bothner (bothner@kalessin.cygnus.com)
7232 * ch-convert.c (digest_constructor): Convert element to element_type.
7233 * ch-parse.y (end_function): Use DECL_ARGUMENTS to check
7234 for parameterless process.
7236 Fri Oct 1 13:57:30 1993 Per Bothner (bothner@kalessin.cygnus.com)
7238 * ch-typeck.c (chill_location): New function.
7239 Based on lvalue_p, but also handle Chill-specific VARY_ARRAY_REF.
7240 * ch-typeck.c, ch-tree.h (CH_LOCATION_P), ch-convert.c: Use
7241 chill_location instead of lvalue_p.
7244 Fri Oct 1 11:28:42 1993 Bill Cox (bill@cygnus.com)
7246 * ch-convert.c (convert): Back out Michael's changes, unintentionally
7248 * ch-lex.l (handle_use_seizefile_directive): No longer downcase
7250 * ch-parse.y (sendaction): Fix a couple of seg faults. Comment out
7251 SEND BUFFER processing for now.

7260 ch-convert.c (convert): Use it.
7261 * ch-typeck.c (build_chill_slice): Take length rather than upper
7262 bound. This makes it easier to recognize that A(X UP LENGTH)
7263 really has fixed length. Also, if the argument is string,
7264 mark the slice as a string too. Also, handle varying strings.
7266 * ch-typeck.c (conflate_singleton_strings): New global.
7267 * ch-typeck.c (chill_similar): If conflate_singleton_strings is
7268 set (as it currently is), allow CHARS(1)/BOOLS(1) to be similar
7269 to CHAR/BOOL, as required by the 1984 version of Z.200.
7270 * ch-convert.c (convert_to_char): Convert CHARS(1) to CHAR.
7271 * ch-convert.c ( build_array_type_for_scalar): If input is string,
7273 * ch-convert (maybe_turn_scalar_into_arra), ch-tree.h: Removed.
7274 * ch-convert.c (convert): Convert CHAR to CHARS(1).
7276 This fixes 'X // := Y' and is also a general simplification.
7277 * ch-actions.c (chill_expand_assignment): Convert 'LHS OP := RHS'
7278 to 'LHS := LHS OP RHS' (using stabilize_reference on LHS).
7279 Also, call save_expr on RHS if a multiple assignment.
7280 * ch-parse.y (assignaction): Therefore, no longer need to call
7281 stabilize_reference on RHS.
7282 * ch-typeck.c (build_chill_modify_expr), ch-tree.h: Remove
7283 modifycode parameter. Make it the caller's responsibility to
7284 handle <assigning operator>.
7285 * ch-actions.c, ch-decl.c, ch-except.c, ch-expr.c, ch-grant.c,
7286 ch-loop.c: Fix calls to build_chill_modify_expr accordingly.
7288 Wed Sep 29 18:02:55 1993 Per Bothner (bothner@kalessin.cygnus.com)
7290 * ch-lang.c (string_index_type_dummy), ch-tree.h: New variable.
7291 * ch-decl.c (integer_minus_one_node), ch-tree.h: New variable.
7293 * ch-parse.y (arrayindex: modename): Remove useless code.
7294 * ch-satisfy.c (satisfy): Don't gag on string_index_type_dummy,
7295 * ch-tree.c (build_string_type): Pass string_index_type_dummy as
7296 the parent type of the index range.
7297 * ch-typeck.c (layout_chill_range_type): Recognize and handle
7298 string_index_type_dummy - specifically allow an empty range.
7300 Wed Sep 29 13:36:23 1993 1993 Bill Cox (bill@cygnus.com)
7302 * ch-convert.c (convert_to_reference): Check for loc-identity
7303 mismatches correctly (and remove one of those chill_compatible
7305 * ch-decl.c (decl_tasking_code_var): New function, called from
7306 push_extern_process and push_extern_signal.
7307 * ch-parse.y (end_function): Delete parameter. Check current_function_decl
7308 whether it's actually a process, and whether it has parameters.
7309 Make Michael's change simplifying the pass 2 test, preventing a seg
7311 (procedure, process): Change calls to end_function, remove
7312 code saving value from build_process_header. Delete redundant chill_
7313 phrases from some function calls.
7314 * ch-tasking.c: Remove some redundant _chill phrases from function
7316 * ch-tree.h: Remove some redundant _chill phrases from function
7317 names. Add the CH_VARYING_ARRAY_TYPE macro, call it from
7318 all relevant places.
7319 * ch-typeck.c: Use the new macro. Cast TREE_CODEs to chill_tree_code.
7321 Wed Sep 29 13:07:43 1993 Per Bothner (bothner@kalessin.cygnus.com)
7323 * ch-convert.c (convert_to_reference): Remove redundancies.
7324 * ch-convert.c (convert): Handle convert_to_reference
7325 with a recursive convert call.
7326 * ch-decl.c (do_decl): Add missing compatibility-checking
7327 of initializer (don't depend on convert).
7329 Tue Sep 28 00:02:25 1993 Per Bothner (bothner@kalessin.cygnus.com)
7331 * ch-tree.h (CH_LOCATION_P): New macro.
7332 * ch-typeck.c (layout_chill_range_type): Fix call to
7333 type_for_size, when figuring out a defaulted parent type.
7334 * ch-expr.c (build_chill_lower, build_chill_sizeof): Check
7335 for TREE_CODE_CLASS != 't' rather than == 'd'.
7336 * ch-expr.c (build_chill_function_call): Use CH_LOCATION_P
7337 to check for location, rather than TYPE_CODE_CLASS == 'd'.
7339 * ch-tree.c (build_string_type): Make 2-pass safe. Also,
7340 change parameter to be length, not index type.
7341 * ch-parse.y (mode2), ch-expr.c (build_concat_expr), ch-lex.l
7342 (build_chill_string): Modify callers of build_string_type accordingly.
7343 * ch-lex.l (check_newline): Don't look for # directive inside a
7345 * ch-grant.c (grant_array_type): Make more robust for char-
7346 and bit-strings (allow non-constant sizes). Change parameters
7347 and return types. (raw_decode_mode): Use grant_array_type
7348 for bitstrings. (otherwise): Fix grant_array_type callers.
7350 Mon Sep 27 16:57:57 1993 Per Bothner (bothner@kalessin.cygnus.com)
7352 Remove changes of Sep 15.
7353 * ch-tree.h (CH_SINGLETON_DOMAIN): Removed.
7354 * ch-typeck.c (chill_similar): Don't allow a singleton
7355 powerset to be similar to its domain.
7356 * ch-convert.c (convert_to_boolean): Don't convert a singleton
7357 SET_TYPE constructor to a Boolean.
7359 * ch-actions.c (chill_expand_assignment): Handle IN_EXPR on
7360 LHS of assignment, which is what we're current (temporarily?) using.
7362 Mon Sep 27 06:01:57 1993 Bill Cox (bill@rtl.cygnus.com)
7364 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
7365 ch-grant.c, ch-inout.c, ch-parse.y, ch-satisfy.c,
7366 ch-tasking.c, ch-tree.c, ch-tree.h, ch-typeck.c:
7367 -Wall cleanup. Add prototypes where missing.
7368 Delete unused variables. Cast uses of tree_codes
7369 to chill_tree_code, which they are.
7371 Sun Sep 26 13:09:57 1993 Bill Cox (bill@rtl.cygnus.com)
7373 * ch-decl.c (do_decl): Save initializer in pass zero
7375 * ch-lex.l: Fix comments, indentation.
7376 * ch-parse.y: Standardize error messages to use
7377 uppercase for CHILL keywords rather than quoting them.
7378 Suggestion from docs department.
7379 * ch-tasking.c: Pervasive changes to get processes to
7381 * ch-tree.h: Delete prototypes for functions whic
7382 I made static inside ch-tasking.c.
7384 Sun Sep 26 02:40:02 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7386 * ch-lex.l (yywrap): Call `check_newline' in case the file
7387 started with a line directive.
7389 Sat Sep 25 13:54:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
7391 * ch-decl.c: Expand pre-amble comment.
7392 * ch-decl.c (struct scope, push_module): Use new field
7393 tail_chain_module to build child-module list in order.
7394 (Just to make compiler debugging a little less confusing.)
7396 * ch-decl.c (struct scope): New field weak_decls.
7397 * ch-decl.c (find_implied_types): New interface. Now pre-pend
7398 new enum types to a given input list. This makes it easier to
7399 avoid duplicates, which should at least be more efficient.
7400 Also, handle FUNCTION_DECL.
7401 * ch-decl.c (bind_saved_names): Removed. Distribute its
7402 functionality over new functions (push_scope_decls, pop_scope_decls,
7403 build_implied_names, bind_sub_modules). The goal (which seems to
7404 have been more-or-less attained) was to fix weak name handling.
7405 * ch-decl.c (poplevel): Use new function pop_scope_decls.
7407 * ch-tasking.c (build_signal_struct, build_tasking_message_type):
7408 Use build_decl directly, rather than grok_chill_fixedfields
7409 (which depends on ignore_exprs and has more overhead).
7410 * ch-tasking.c (build_signal_struct): Construct the type
7412 * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
7413 than build_array_ref (which does C-specific "optimizations").
7414 (Hence move my_build_array_ref up earlier in the file.)
7416 Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7418 * ch-tasking.c: Declare static variable `void_ftype_void'.
7419 (chill_tasking_init): Initialize `void_ftype_void' here.
7420 (build_tasking_struct): Use, don't declare `void_ftype_void'.
7421 (generate_tasking_code_variable): Call `do_decl', not
7422 `decl_temp1' to declare TASKING_CODE_NAME.
7423 (tasking_setup): Drop into 1-pass mode so that all
7424 tasking-related declarations are installed in the global
7425 scope. Use correct CHILL types for initializers (since
7426 ptr_type_node doesn't have the right meaning for CHILL).
7427 Also, call `do_decl' instead of `decl_temp1' for
7429 (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
7430 `chill_finish_compile' in sync between passes.
7432 * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
7433 declarations on pass zero. Keep obstacks in sync, and always
7434 call `finish_decl' for pass zero declarations.
7435 (push_chill_extern_function): Keep obstacks in sync, and always
7436 call `finish_decl' for pass zero declarations.
7437 (build_enumerator): Ditto.
7438 (grok_chill_variantdefs): Change PASS test to exclude only
7440 (finish_struct): Ditto.
7441 * ch-expr.c (build_chill_component_ref): Ditto.
7442 (build_chill_binary_op): Ditto.
7443 * ch-tree.c (build_powerset_type): Ditto.
7444 (build_bitstring_type): Ditto.
7445 * ch-typeck.c (build_chill_range_type): Ditto.
7446 (build_chill_struct_type): Ditto.
7448 * ch-decl.c (build_chill_exception_decl): Clarify reasons for
7449 extra pushing and popping of obstacks.
7451 * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
7452 on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
7454 * ch-grant.c (chill_finish_compile): Clear out both
7455 MODULE_INIT_LIST and TASKING_LIST if either contains stuff
7458 * ch-parse.y (rccase_label): Add NAME rules so that pass one
7459 works w/o knowing we're parsing a signal. Simplify SIGNALNAME
7460 rules since we only get SIGNALNAME tokens in pass two.
7461 (sendaction): Ditto.
7462 * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
7463 BUFFERNAME on pass two. The grammar now handles this.
7464 * ch-decl.c (lookup_remembered_decl): Deleted.
7466 Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
7468 * ch-decl.c (lookup_remembered_names): Removed. It was being
7469 misused in ch-lex.l.
7470 * ch-lex.l (name_type_signal): Revert last change. Basically,
7471 we cannot use the C typedef/variable name trick in CHILL, due
7472 due to the language's 2-pass nature.
7473 * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
7475 * ch-tree.h (lookup_remembered_name): Comment out the prototype.
7477 Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7479 * ch-decl.c (do_decl, push_chill_extern_function): Change pass
7480 checks so the pass == 0 case is handled for built-in types.
7481 (push_modedef): Add check for error_mark_node.
7482 (lookup_remembered_decl): New function.
7483 (pushlevel, poplevel) Change pass checks.
7484 (pushdecl): Check type as well for NULL.
7485 (build_enumerator): Handle pass == 0 case.
7486 * ch-lex.l: Use lookup_remembered_decl to get lastiddecl
7488 * ch-parse.y: Set pass to zero to indicate initial decl processing.
7489 Replace NAME references with SIGNALNAME references.
7490 (startaction): Only check copy number if not ignoring actions.
7491 Always call build_chill_start_process.
7492 (optstartset): Don't lookup the instance name.
7493 * ch-tasking.c (generate_tasking_code_variable): Replace
7494 do_decl call with decl_temp1 call.
7495 (build_chill_start_action): Check for ignore_actions here.
7496 (build_tasking_message_type): Layout the type.
7497 (rc_state_type): New structure to keep nested receive-case
7499 (build_chill_receive_case_start, build_chill_receive_case_end):
7503 Fri Sep 24 04:19:15 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7505 * ch-tasking.c (build_chill_receive_case_start): `namedecl'
7506 should be a _DECL, not an IDENTIFIER_NODE.
7508 Thu Sep 23 18:18:24 1993 Per Bothner (bothner@kalessin.cygnus.com)
7510 * ch-decl.c (find_implied_types): Handle VAR_DECLs.
7512 * ch-decl.c (print_lang_identifier): Print IDENTIFIER_OUTER_VALUE.
7513 * ch-actions.c (chill_expand_result): Allow value-less RETURN.
7514 * ch-expr.c (resolve_component_ref): Recognize error_mark.
7516 * ch-convert.c (digest_constructor): Handle a nested powerset tuple.
7517 * ch-satisfy.c (satisfy): Use return value of layout_chill_range_type.
7518 * ch-typeck.c (chill_similar): Repeatedly get parent modes
7519 of ranges, not just once.
7520 * ch-typeck.c (chill_root_resulting_mode), ch-tree.h: New function.
7521 * ch-typeck.c (layout_chill_rang_type): Re-do type-checking
7522 to follow Blue Book better (check for Compatibility).
7524 * ch-tree.h (CH_ROOT_RESULTING_MODE): New macro.
7525 * ch-lex.l (use_seizefile_name, current_seizefile_name), ch-tree.h:
7526 New variables. The latter replaces in_seizefile.
7528 Changes to store in the new DECL_SEIZEFILE field each seize
7529 ALIAS_DECL the name in the most recent use_seize_file directive.
7530 (This requires that use_seize_file directives written to the
7531 grant file be written before the SEIZEs that need it.)
7532 Allow clashing declarations granted into the global scope
7533 (produce a warning), but remember the seizefile case from
7534 (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
7535 The a SEIZE will select the granted decl that matches its
7536 DECL_SEIZEFILE (in other words: grants from the most recent
7537 use_seize_file will be preferred).
7538 * ch-tree.h (DECL_SEIZEFILE), ch-tree.def: New macro.
7539 * ch-tree.h (global_value, IDENTIFIER_GLOBAL_VALUE): Renamed
7540 to outer_value, IDENTIFIER_OUTER_VALUE.
7541 Changes to cause the use_seize_file directives to be written
7542 out in order as they're seen in source.
7543 * ch-lex.l (files_to_seize, next_file_to_seize, last_file_to_seize):
7544 Changed to have type TREE_LIST of pointer to IDENTIFIER_NODE.
7545 * ch-lex.l (handle_use_seizefile_directive): Modify appropriately.
7546 Don't call grant_use_seizefile.
7547 * ch-lex.l (mark_use_seizefile_written): New function.
7548 * ch-grant.c (decode_decl): Write out use_seize_file directive,
7549 if needed, before writing a seize declarations.
7550 * ch-decl.c (pop_module): Handle decls granted into the global
7551 module specially, setting IDENTIFIER_OUTER_VALUE.
7552 * ch-decl.c (lookup_name_for_seizing): Check IDENTIFIER_OUTER_VALUE.
7554 Thu Sep 23 19:05:37 1993 Bill Cox (bill@cygnus.com)
7556 * ch-decl.c (push_chill_extern_process): Delete unused variables,
7557 declare the process' tasking_code variable as external.
7558 * ch-parse.y (process): Force ignore_exprs to FALSE while parsing
7560 * ch-tasking.c (sigdef): Move resetting of quasi_signal from here
7562 * ch-tree.h: Add prototype.
7563 * expr.c (store_constructor): Emergency first-aid. Rewrite later.

10259 * ch-lex.l: Re-write to use start states, to avoid calling
10260 yylex() recursively.
10261 * ch-lex.l (compiler_directive); This is now obsolste. FIXME.
10262 * ch-lex.l: Call push_module and pop_module when reading a
10263 seizefile. This creates a pseudo-module.
10264 * ch-parse.y: Clean up handling of empty declarations and
10265 action statements; semicolons are now optional a number of
10267 * ch-parse.y: Remove some bogus tests for "statement
10268 out of sequence" (they're both legal and work).
10269 * varasm.c (mak_function_rtl): Remove kludge that may
10270 not be necessary (and loses anyway).

10372 Fri Apr 2 21:55:14 1993 Per Bothner (bothner@rtl.cygnus.com)
10374 Major re-write of New module/seize/grant stuff.
10375 Now, a grantfile is a spec module and contains all the
10376 top-level declarations of the granting module, not just
10377 those that are granted. It also contains explicit grant
10378 statments naming those declared names that are granted.
10379 It also has seize statements and use_seize_file directives
10380 to correctly handle transitive dependencies.
10382 * ch-parse.y: Change to allow multiple modules per source file.
10383 Allow spec modules (including quasi definitions) as well as
10385 Allow spec modules inside normal modules; these behave as if
10386 they were outermost. This violates the Blue Book, but is
10387 needed by the new grantfile mechanism. (A grant file is a
10388 spec module that gets included by the use_seize_file directive.)
10389 * ch-parse.y (struct module *current_module, push_module,
10390 pop_module): Support module nesting (for spec modules only).
10392 * ch-tree.h (struct module): New.
10393 * ch-grant.c (granted_decls): New list of declarations
10394 that have been granted into the outermode pseudo-module.
10395 * ch-grant.c (decode_mode): If the decl has a name,
10396 always write the name, not just if the decl has already
10397 been written. Since we write out all decls, we can assume
10398 it will be written later, and depend on the forward
10399 declaration kludges to catch it.
10400 * ch-grant.c (decode_decl): Don't write out _EXTERN.
10401 Instead write out standard (Blue Book) quasi-definitions.
10402 * ch-grant.c (push_granted): New function.
10403 * ch-grant.c (seize_implied_names): New function. Re-write
10404 how set element names are seized when a set type is seized.
10405 * ch-grant.c (chill_seize): Work by seraching the
10406 granted_decls list and copying the declaration.
10407 * ch-grant.c (chill_grant): Write all declarations
10408 declared in this module. Write GRANT statements for
10409 those granted. seize statements for decls seized from
10410 other modules. Write extra syntax to make a complete
10412 * ch-grant.c (grant_use_seizefile): Copy use_seize_file
10413 directives into grant file.
10414 * ch-lex.l (setup_seizefile_read): Call grant_use_seizefile.
10416 * ch-lex.l (struct input_state, current_input_state,
10417 push_input_file, pop_input_file): New (type, variable,
10418 function*2). Used to save and restore state on an input file.
10419 * ch-lex.l: Clean up to handle nested input seizefiles
10420 (needed by new grant/seize mechanism.
10421 * ch-lex.l (skip_to_end_of_directive): New function.
10422 * ch-lex.l (compiler_directive: USE_SEIZE_FILE): Make sure
10423 we skip to the end of the directive *before* we switch
10425 * ch-lex.l (setup_seizefile_read): Prevent reading the
10426 same seizefile twice (otherwise likely with new grant/seize).
10427 * ch-lex.l: Recognize SPEC. Misc cleanups.
10429 * ch-parse.y: Fixed foreward references of types.
10430 Removed the unknown_type_node crock.
10431 * ch-decl.c: Remove all uses of unknown_type_node.
10432 Check for TYPE_SIZE zero instead.
10433 * ch-decl.c (fixup_unknown_type): Make sure new mode
10434 gets copied into old mode. Merge their variant chains.
10435 * c-decl.c (lookup_name_current_level): Make non-static.
10436 * ch-decl.c (lookup_name_current_level): No longer needed.
10438 * ch-parse.y (call): Allow an implicitly defined function
10439 name following the CALL keyword.
10440 * ch-tree.h (struct lang_identifier): Add implicit_decl,
10441 and make sure order of fields matches c-tree.h.
10443 * ch-actions.c (lang_init, build_allocate_memory_call,
10444 build_allocate_globals_memory_call): Fix names (add initial '_')
10445 and prototypes of _allocate_[global_]memory (2nd param is ref).
10446 Use build_chill_function_call, not build_function_call,
10447 so the reference parameter gets handled.
10448 * ch-actions.c. (lang_init): Make sure boolean_{true,false}_node
10449 have boolean_type_node as their types.
10450 * ch-actions.c (build_chill_lower, build_chill_upper): Fix to
10451 work for arrays with BOOLEAN_TYPE ranges (and simplify some).
10453 * ch-except.c: Make sure an end_label is generated,
10454 and jump to it if there is no exception.
10456 * ch-convert.c (convert_to_reference): Strip off NOP_EXPR casts.
10457 * expr.c (expand_expr): Handle NOP_EXPR as Chill-style casts.
10458 (Need cleaning up and FSF installation!)
10459 * ch-parse.y: If taking the address of a cast, move the
10460 ADDR_EXPR inside the NOP_EXPR.
10462 * ch-typeck.c (my_build_array_ref): Simplified, more suitable
10463 versions of build_array_ref from c-decl.c. (E.g. don't barf
10464 if index type is char or bool.)
10465 * ch-typeck.c (build_chill_array_ref): Use my_build_array-ref.
10467 * ch-typech.c (build_chill_bin_type): New function.
10468 Support BIN(N) range type specification.
10469 * ch-parse.y (mode2), ch-lex.l: Recognize BIN(N).
10471 * ch-tree.h (CH_SIMILAR): Redefine in terms of chill_similar.
10472 * ch-typeck.c (chill_similar): New function. Recognize that
10473 that range types are similar to their parent types.
10475 * ch-tree.h: Declare flag_local_loop_counter.
10476 * ch-loop.c: Whether the loop variable is local to the loop
10477 in now controlled by flag_local_loop_counter, instead of
10478 #ifdef'd on CREATE_SCOPE.
10479 * ch-actions.c (lang_decode_option): Recognize flags
10480 "-f[no-]local-loop-counter".
10481 * toplev.c (lang_options): Add Chill flags -f[no-]local-loop-counter.
10483 * varasm.c (make_function_rtl): Due to problems with forward
10484 references, don't rename nested functions in Chill. (Kudge!)
10486 Sun Mar 28 10:12:45 1993 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10488 * ch-lex.l (push_back, readstring): Fix prototypes.
10490 Fri Mar 26 18:32:15 1993 Bill Cox (bill@rtl.cygnus.com)
10492 * ch-parse.y: Put %type directives back into alpha order.

10507 * ch-parse.y (action): Add recognition for allocate_memory and
10508 allocate_global_memory system calls.
10509 (mode2): Remove ill-conceived error check that broke REFs to
10510 as-yet-undeclared types. Check for IDENTIFIER_NODE, lookup its
10511 DECL if there, pass TREE_TYPE of decl to build_pointer_type.
10512 (variantfields, varianthack): Clean up.
10513 (variantfield): Check for IDENTIFIER_NODE, lookup its DECL if
10514 there, pass TREE_TYPE of decl to grok_fixedfields.
10515 (labellist): Explicitly assign error_mark_node to signal error.
10516 * ch-typeck.c (chill_compatible): Report FALSE for bad parameters,
10517 rather than seg faulting.

10549 array and its type get on the permanent obstack.
10550 * ch-grant.c (write_grant_file): Don't write the _INIT=name
10551 specifier: It isn't needed, and loses (because of funny
10552 characters in the chill_initializer_name).
10553 * ch-decl.c (push_synmode): Set TYPE_NAME(mode) = syndecl.
10554 * ch-lang.c (finish_chill_enum): Don't allocate a dummy
10555 TYPE_DECL for the enum. I don't think it is needed (?),

10596 was intended to be equality test. Remove unused variables.
10597 * ch-tree.h: Add prototype. Remove unused EXCP_CODE enumeration, and
10598 prototyping editorial comments.
10599 * ch-typeck.c: Disable generation of code to validate array index for
10600 now. Should be done as a call-back from more generic array_ref code.

10720 * c-decl.c (init_decl_processing): Disable initial creation of C-specific
10721 builtins - they pollute the CHILL name space.

10723 * expr.c (expand_expr): Use actual library name for __inpowerset
10725 * stor-layout.c (variable_size): Disable complaint about variable-
10726 size type or decl at file scope. Perhaps later this s.b. a warning.

10733 * ch-actions.c: Change all builtin functions names to their
10734 actual library names. Change references to boolean_type_node
10735 to references to the TREE_CODE == BOOLEAN_TYPE, to follow the
10737 build_set_expr: Remove length parameter, call powersetlen() instead.
10738 remove handling of CHAR arrays - they're handled in build_char_array_expr.
10739 Call __eqpowerset to test for equality - we can't use a byte-length -
10740 need bitcount instead.
10741 build_chill_compound_expr, internal_build_compound_expr: Copy from C
10742 version that does stuff we don't want.
10743 build_binary_op: Check for in_size_in_bytes return < 0, indicating

10749 build_chill_length: Move VARYING array handling before regular char
10751 * ch-expr.c chill_expand_expr: Disable concatenate code - we need to
10752 the VARYING status of the target to do this correctly. Use powersetlen
10753 for the powerset operations, not a byte length.
10754 * ch-loop.c: Make CREATE_SCOPE #define to enable creation of a new scope
10755 for each CHILL loop, as Z.200 requires. Add powerset and error flags
10756 to loop structure. Evaluate user's powerset expression into a temp,
10757 scan it destructively with __ffsetclrpowerset or __flsetclrpowerset
10758 for powerset loop. Only do loop-end assignments if NOT a powerset
10759 loop, which has much less overhead now.

10805 comes out error_mark_node, set ERRONEOUS.
10807 * ch-actions.c (build_chill_binary_op_1): If EXP is NULL_TREE,
10810 * ch-action.c (chill_comptypes): Test for structural
10811 equivalence of enums.

10821 * c-typeck.c (process_init_constructor): Emit error if some
10822 array elements are not initialized.
10823 * c-typeck.c (process_init_constructor): Call digest_init()
10824 recursively to expand default_value.

10991 * ch-typeck.c (convert): Avoid needlessly (and lossingly) calling

11023 * ch-parse.y: Add working exception handling support.
11024 * ch-lex.l, ch-parse.y: Prefer standard type terminology
11025 (BOOLS, CHARS) even though non-standard (BITS, CHAR) is ok.
11026 * ch-grant.c: Fix various problems related to granting
11027 types such as bitsets.
11028 * ch-tree.c (build_bitstring_type): Set TYPE_MIN_VALUE

11032 * ch-tree.h, ch-actions.c (lang_init), ch-grant.c (decode_mode):

11035 New types chill_integer_type_node and chill_unsigned_type_node
11036 that correspond to the Chill source types INT and UINT.
11037 For now, these match the C 'short' types, but that should
11038 become a configuration option later,

11042 * ch-actions.c (build_chill_unary_op): allow NOT of a set.

11053 * ch-tree.h: remove prototypes added to c-tree.h.

11060 * ch-tree.def: add a new tree type - just for varying array
11061 references. We were using ARRAY_REF, but the underlying C
11062 code also generates that one.

11084 * ch-typeck.c (build_chill_array_ref): Cause rangefail if

11108 * ch-grant.c (set_default_grant_file): Change default.
11109 Normally, grant file should end up in cwd.
11110 * ch-lang.c (build_chill_struct_type): Call pushtag,
11111 for the sake of debugging.
11112 * ch-lex.l: Improve comment parsing.

11474 * ch-grant.c (chill_start_module_code): Make sure the
11475 init_name starts with the magic string also used for C++
11476 initializers. Also, don't embed the file name in the name,

11531 * ch-lex.l (check_newline): Use the orginal versions (derived
11532 from the C code, not the simplified, special-case version).
11533 Also, fix that version of check_newline to not call yylex()
11535 * ch-lex.l (yy_input): Call check_newline to handle
11536 newlines and check for # directives.
11537 * ch-lex.l (syntax): Don't recognize #-directives; these

11539 * ch-actions.c (lang_init): Call the modified version of
11540 check_newline(). Do this at the *after* we've initialized
11541 standard types, so this can be done while lineno is still 0.

11569 * ch-lex.l (yy_input): Re-write to return more than one
11570 character at a time (execpt when reading seize-files).
11571 Don't increment lineno until we start reading the next line.
11572 This fixes some off-by-one errors in lineno.
11574 Wed Dec 30 16:15:23 1992 Per Bothner (bothner@rtl.cygnus.com)
11576 * ch-convert.c: Assume use of new common.c.
11577 * ch-convert.c (convert_to_reference, convert_from_reference):
11578 New routines, to handle loc-identity declared variables and
11579 LOC parameters (both of which are implemented as references).
11580 * ch-lang.c (convert_to_boolean, convert_to_char): Move to
11581 ch-convert.c, where they would seem to belong.
11582 * ch-convert.c (convert): New function, since we no longer
11583 link in c-convert.c.
11584 * ch-expr.c (chill_expand_assignment): Handle by calling
11585 convert() instead of chill_comptypes().
11586 Also handle the LHS being a reference.
11587 * ch-parse.y: Add a procedure call as an action.
11588 * ch-parse.y (locdec, optlocinit): Move handling of
11589 loc-identity declarations from optlocinit to locdec
11590 - and add working semantics for it.

11592 * ch-parse.y (grantstatement etc): Don't bother making list.
11593 * ch-lex.l: #include <sys/types.h> before <sys/stat.h>.

11597 * ch-parse.y, ch-expr.c: add support for declaring & assigning
11599 * ch-typeck.c: allow VARYING structures in assign_type_to_expr.
11601 Tue Dec 29 15:28:48 1992 Bill Cox (bill@cygnus.com)
11603 * ch-actions.c: implement expressions of arrays of char,
11604 ( concatenation, relationals ), correct type of code parameters
11605 * ch-expr.c: correct type of code parameters
11607 Tue Dec 29 11:16:19 1992 Bill Cox (bill@cygnus.com)
11609 * ch-decl.c: cleanup.
11610 * ch-parse.y: put emit_line_note() calls in lotsa places,
11611 per Fred's request; be sure that statements get counted also.
11612 * ch-lex.l: standardize function headers.
11614 Tue Dec 29 10:41:56 1992 Fred Fish (fnf@cygnus.com)
11616 * ch-decl.c (start_chill_function): Always return 1, rather
11617 than a random value.
11618 * ch-lex.l (check_newline): Add a version for chill that
11619 just snarfs the right value for main_input_filename out of
11620 the first line of the input file, without disturbing the
11621 lexer state or requiring it's assistance.
11622 * ch-actions.c (lang_init): Call check_newline, like the
11623 other language frontends, to get main_input_filename set
11624 from first line of input file.
11626 Mon Dec 28 18:49:01 1992 Bill Cox (bill@cygnus.com)
11628 * ch-parse.y: clean up conflicts. The remaining one is

11633 * ch-parse.y, ch-lex.l, ch-actions.c: add stubs for I/O,
11634 clean up some parser conflicts.
11636 Mon Dec 28 15:00:20 1992 Bill Cox (bill@cygnus.com)
11638 * ch-parse.y, ch-lex.l: add keywords and parsing for most of
11641 Sat Dec 26 20:48:23 1992 Fred Fish (fnf@cygnus.com)
11643 * chillrt/chillrt0.c: Oops, SVR4 doesn't need leading '_'
11644 on build_exceptions.
11646 Sat Dec 26 11:00:36 1992 Fred Fish (fnf@cygnus.com)
11648 * ch-grant.c (chill_finish_module_code): Call
11649 assemble_constructor_alias rather than assemble_constructor.
11650 * varasm.c (assemble_constructor_alias): New function,
11651 like assemble_constructor, but also handles the case where
11652 ASM_OUTPUT_CONSTRUCTOR is not defined and GNU ld is not
11653 being used. Emits a symbol table alias name with the correct
11654 prefix for collect to find and add to the __CTOR_LIST__.
11655 * chillrt/chillrt0.c: Build on previous hack that gets
11656 _build_exceptions into the __CTOR_LIST__, to make it work
11657 for both the non GNU-ld case and for the SVR4 case.
11659 Tue Dec 22 18:24:55 1992 Bill Cox (bill@cygnus.com)
11661 * ch-loop.c: clean up location enumeration - one more

11675 ch-loop.c: rough draft of location enumeration
11676 ch-lex.l, ch-expr.c, ch-decl.c: minor cleanup
11677 ch-actions.c: finish making pred() and succ() work.
11679 Mon Dec 21 10:04:35 1992 Bill Cox (bill@cygnus.com)
11681 * ch-actions.c: allow pred(char) and succ(char).
11683 Sun Dec 20 16:04:28 1992 Bill Cox (bill@cygnus.com)
11685 * ch-expr.c, ch-actions.c, ch-parse.y, ch-loop.c,
11686 c-expr.c: make DO WITH work.
11688 Sun Dec 20 12:22:53 1992 Bill Cox (bill@cygnus.com)
11690 * ch-loop.c, ch-actions.c, ch-typeck.c: powerset loops
11693 Sat Dec 19 14:20:23 1992 Per Bothner (bothner@cygnus.com)
11695 * c-typeck.c (process_init_constructor): Add warning if
11696 there is a duplicate default initializer element.
11697 * ch-typeck.c (chill_give_type_to_expr): New function,
11698 to handle coercion of an expression to context-given type,
11699 Takes care of untyped tuples, and case expressions.
11700 * ch-decl.c (do_decls), ch-typeck.c (chill_expand_return,
11701 chill_expand_result), ch-parse.y <assignaction>:
11702 Use chill_give_type_to_expr().
11703 * ch-typeck.c (chill_handle_case_label): New parameter list,
11704 to handle the (new) conventions for <case_label>, including
11705 default elements and ranges.
11706 * ch-parse.y <expanded_case_label>, ch-typeck.c
11707 (expand_case_expr): Use new version of chill_handle_case_label.
11708 * ch-decl.c (push_syndecls): Change parameters: Instead of
11709 TREE_LIST representing a compete <synonym definition statement>,
11710 just pass the parts of a single <synonym definition> as 3
11711 different parameters. Also, use chill_give_type_to_expr(),
11712 to handle untyped tuples in the RHS.
11713 * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct
11714 a tree - just call push_syndecls() on each <synonum_definition>
11716 * ch-parse.y (exprlist_get_single): Remove; no longer needed.
11717 * ch-parse.y: Handle <tuple> without mode name diferently from
11718 <tuple> with mode name. The latter is a <primval> that can be
11719 in most contexts, but if the <mode name> is missing, the <tuple>
11720 is only allowed in certain contexts. Use the new non-terminal
11721 <untyped_expr> to indicate those contexts where untyped tuples
11722 (and case expressions) are valid because the expression gets a
11723 type from its context (such as the RHS of an assignment).
11724 Use chill_give_type_to_expr in those contexts.
11726 Sat Dec 19 14:01:26 1992 Bill Cox (bill@cygnus.com)
11728 * ch-actions.c, ch-loop.c, Makefile.in: looping stuff.
11730 Sat Dec 19 10:16:20 1992 Bill Cox (bill@cygnus.com)
11732 * ch-parse.y: clean up warning messages from byacc. bison
11733 still complains thrice.
11735 Fri Dec 18 12:33:29 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11737 * ch-actions.c (maybe_chill_comptypes): Delete unused
11739 (chill_comptypes): Add new parameter ERRSTR. All callers
11741 (build_chill_binary_op): Fix indentation to match GNU coding
11744 Fri Dec 18 08:18:13 1992 Bill Cox (bill@rtl.cygnus.com)
11746 * ch-parse.y, ch-expr.c, ch-actions.c, expr.c: major

11756 a default initializer element.
11757 * ch-parse.y: Implement default elements for tuples
11758 (as in '(else):' and '(*):' ).
11760 * ch-parse.y: Previous change to dis-ambiguate case-labels
11761 seems to have allowed getting rid of all of the expr_or_list hair.
11762 * ch-decl.c (do_decls): Undo Tiemann's change to "Handle
11763 initialization of multiple variables by a tuple" - the
11766 Wed Dec 16 11:17:53 1992 Bill Cox (bill@cygnus.com)
11768 * ch-parse.y: complete re-write of DO statement handling.
11769 now operational, except WITH is stubbed out. Improved
11770 syntax error message.
11771 * ch-actions.c: DO support: high_domain_value(), low_domain_value ().
11772 * ch-expr.c: fixes to IN_EXPR handling.
11774 Tue Dec 15 17:15:13 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11776 * ch-grant.c: Add casts to alloca return to avoid compiler warning.
11777 * ch-lex.c: Likewise.
11779 * Makefile.in (ch-lex.c): Delete incorrect free declaration added
11780 by flex to avoid compiler error.

11785 variables by a tuple.
11787 * ch-decl.c (do_decls,start_chill_function): Make DECL public
11788 if we're doing a GRANT ALL at top level.
11790 * ch-lang.c (build_range_type): Deal with typecast to CHAR in
11793 * c-typeck.c (digest_init): SET_TYPE is not a scalar type.
11794 BOOLEAN_TYPE and CHAR_TYPE are scalar types.
11796 Mon Dec 14 14:58:32 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11798 * ch-lex.l (get_chill_{linenumber,filename}): New functions.
11799 (convert_number): Use LONG_TYPE_NODE instead of INTEGER_TYPE_NODE.
11801 Mon Dec 14 13:36:44 1992 Bill Cox (bill@cygnus.com)
11803 * expr.c: install and test newer Pascal IN_EXPR code,
11804 but don't activate it - it's very verbose.
11806 Mon Dec 14 00:22:49 1992 Fred Fish (fnf@cygnus.com)
11808 * Makefile.in (LANGUAGES): Add chill.
11809 * Makefile.in (CHILL_INSTALL_NAME, CHILL_CROSS_NAME):

11824 Sun Dec 13 14:07:32 1992 Bill Cox (bill@cygnus.com)
11826 * ch-actions.c: fix unary operations, modulus ops,
11827 (discovered after extending regression tests).
11829 Sun Dec 13 12:16:32 1992 Bill Cox (bill@cygnus.com)
11831 * resync with Michael and Wilfried

11837 * ch-tree.h: Add declarations for new chill functions that
11838 have been implemented but not (yet) declared.
11840 Sat Dec 12 00:17:23 1992 Per Bothner (bothner@cygnus.com)
11842 * c-typeck.c (process_init_constructor): Warn about duplicate
11843 labels for labelled initializer elements.
11844 * ch-lex.l (various operator tokens, such as "+"): Don't
11845 set yylval.code to a TREE_CODE; this is better done in parser.
11846 * ch-parse.y: Some work with case labels and tuples.
11847 Get literal range as tuple (and case) labels working.
11848 Fix some problems introduced by recent grammar overhaul.

11852 * ch-actions.c, ch-parse.y ch-tree.h ch-expr.c, ch-typeck.c:
11853 got long, real expressions working. We can also call a func-
11854 tion and use its return value.
11856 Thu Dec 10 14:45:17 1992 Per Bothner (bothner@cygnus.com)
11858 * ch-parse.y: Major change to remove or at least identify
11859 parser ambiguities. One result: We now allow actions that
11860 start with '(', as required by teh Blue Book. This does break
11861 some things; look for FIXME for things that need work.
11862 * ch-typeck.c (chill_expand_case_expr): We need an extra
11863 level of looping to (in the future) support <case label
11864 specification>s with more than one <case label list>.
11866 Thu Dec 10 09:21:41 1992 Bill Cox (bill@cygnus.com)
11868 * ch-actions.c, ch-expr.c: Implement string assignments

11888 on arrays of BOOLs.
11890 Mon Dec 7 08:55:20 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11892 * ch-actions.c (lang_init): Set LINENO to 1 at beginning to
11893 indicate we are done with initialization.
11895 * ch-decl.c (do_decls): Set TREE_PUBLIC if we are doing a
11897 (start_chill_function): Ditto.
11899 * ch-lex.c (convert_bitstring): Set TREE_CONSTANT.
11900 (compiler_directive): Don't confuse compiler directives with
11901 equality comparison operators.
11903 * ch-parse.y: Clear CURRENT_LOCNAMELIST after calling do_decls.
11905 Sun Dec 6 13:12:32 1992 Bill Cox (bill@cygnus.com)

11916 * tree.def: Move CARD_EXPR and SET_LE_EXPR back down with the other
11917 Pascal-required ones, since C++ no longer needs them. When
11918 Chill's public, a comment can be added to the effect that
11919 SET_LE_EXPR is also used by Chill.
11921 Fri Dec 4 12:05:01 1992 Bill Cox (bill@cygnus.com)
11923 * Restore CARD_EXPR and SET_LE_EXPR to tree.def.

11962 (push_newmode,push_synmode): Call `fixup_unknown_type' when we
11963 see a declaration that uses `unknown_type_node'. FIXME.
11965 * ch-grant.c (decode_constant): New function.
11966 (decode_decl): Call `decode_constant' for CONST_DECLs.
11968 * ch-lex.l (char action): Use ridpointers instead of
11969 lookup_name to get "char"'s declaration.
11971 * ch-parse.y: Call `build_lang_decl' instead of `build_decl'
11972 when we need to build a TYPE_DECL.
11974 Tue Dec 2 09:44:05 1992 Bill Cox (bill@cygnus.com)
11976 * ch-typeck.c: clean up a gcc warning with a forward
11977 declaration of build_string_type.
11979 Tue Dec 1 16:51:05 1992 Bill Cox (bill@cygnus.com)
11981 * ch-actions.c: completely remove those builtin calls
11982 that are duplicated in c-decl.c
11984 Tue Dec 1 16:38:51 1992 Fred Fish (fnf@cygnus.com)
11986 * ch-actions.c (lang_init): Ifdef out initializations for
11987 __builtin_abs and __builtin_fabs, since they are duplicates of
11988 initializations in c-decl.c, and trigger spurious warnings.
11990 Tue Dec 1 16:35:18 1992 Bill Cox (bill@cygnus.com)
11992 * ch-parse.y: make size() work with a typename argument.

12001 * ch-lex.l: fix char-type
12003 Tue Dec 1 11:10:56 1992 Bill Cox (bill@cygnus.com)
12005 * ch-parse.y, ch-actions: added parsing and processing
12006 for upper, lower, and length built-ins.

12019 Mon Nov 30 17:35:33 1992 Fred Fish (fnf@cygnus.com)
12021 * chillsh: New script frontend (ala g++), installed as "chill".
12022 Can't be called "chill.sh" because make tries to cat it into the
12023 "chill" directory. Can't be called just "chill" cause that's
12024 already there as a directory.
12025 * Makefile.in: Add rules to install chillsh as "chill".
12026 * chill/libchill.c: Temporarily ifdef out stuff that wants
12027 to conflict with i486/SVR4 runtime or wants to pull in librmt.a,
12028 which itself causes linkage to fail.
12030 Mon Nov 30 16:28:19 1992 Bill Cox (bill@cygnus.com)

12040 * ch-lex.l, ch-parse.y: Translate token PFEIL into English ARROW.
12041 * ch-parse.y (op6): Remove handling of string repetition operator,
12042 until we can figure out a way to parse it correctly.
12043 * ch-parse.y (optmodename): New non-terminal.
12044 * ch-parse.y (tuple): Merge the two variants using optmodename.
12045 * ch-parse.y (location): Add semantic actions for
12046 dereferencing operator ->.

12050 * ch-actions.c: removed compile warning, better code for abs.
12052 * ch-parse.y: add productions for builtin functions succ, pred,
12053 abs, and size. Add %tokens also. Sort %tokens alphabetically.
12055 * ch-lex.l: add parsing for builtin function names, such as abs,
12056 pred, succ, etc. Put flex -a option into Makefile.in, so we can
12057 clean up the lexer soon.

12061 * ch-typeck.c (chill_handle_case_label, chill_handle_case_default):
12062 New functions, for code common to CASE actions and expressions.
12063 * chill.y: Replace some code by calls to chill_handle_case_label
12064 and chill_handle_case_default.
12065 * ch-typeck.c (chill_expand_case_expr): Add semantics.
12067 * tree.c: Change doing_chill_thang from extern to common.
12069 Mon Nov 23 18:34:22 1992 Per Bothner (bothner@rtl.cygnus.com)
12071 * ch-tree.def: New CASE_EXPR type, for case expressions.
12072 * ch-expr.c (chill_expand_expr): Hook for CASE_EXPR.
12073 * ch-typeck.c (chill_expand_case_expr): New function.
12074 Placeholder to implement case expressions.
12075 * ch-typeck.c (chill_expand_result, chill_expand_return):
12076 Handle mode-unspecified tuples and case expressions in
12077 the context of RETURN and RESULT actions.
12078 * chill.y (assignaction): Handle case expressions in the
12079 context of the RHS of an assignment action.
12080 * chill.y (caseaction): Remove spurious duplicate OF in grammar.
12081 * chill.y: Handle labeled structure tuples.
12082 * chill.y: New rules to parse CASE expressions.
12083 * tree.c (build_function_types): Allow Chill functions
12084 to return arrays and functions.
12086 Wed Nov 18 13:50:28 1992 Per Bothner (bothner@rtl.cygnus.com)
12088 * ch-typeck.c (chill_expand_tuple): New function. Expand a
12089 tuple (constructor) given an expected (context) type.
12090 * chill.y: Implement 'LHS := TUPLE' using expand_chill_tuple,
12091 using the mode of the LHS and the expected type of the TUPLE.
12092 * chill.y: Implement initialization.
12093 * chill.y: Fix some syntax bugs (forbidlist must be surrounded
12094 by parentheses), and remove or note ambiguities.
12095 * chill.y: Started converting layout style to be like c-parse.in.
12096 * chill.y: Implement IF expressions.
12097 * chill.y: Added syntax rules for tuples. Labelled and unlabelled
12098 array tuples should now work (in some contexts).
12099 * ch-actions.c: Initialize doing_chill_thang to 1.
12100 * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
12101 initializer, to make pushdecl and finish_decl work.
12102 * c-decl.c (convert_for_assignment): If Chill, don't convert
12103 function and arrays into pointers. (Maybe functions should
12104 still be converted?)
12105 * c-typeck.c (grokdeclarator): Allow functions in Chill
12106 to return arrays and functions.
12108 Mon Nov 16 15:40:47 1992 Per Bothner (bothner@rtl.cygnus.com)
12110 * chill.y (exprlist_get_single): New function, used when
12112 * chill.y: Re-did parsing of tuples to remove ambiguities.
12115 Tue Nov 10 16:30:55 1992 Per Bothner (bothner@rtl.cygnus.com)
12117 * ch-typeck.c (chill_expand_result); Set TREE_SIDE_EFEFCTS
12118 flags on assignment to result.
12119 * ch-typeck.c (build_chill_array_ref): Subtract lower
12120 bound of domain if non-zero. Preliminary hook for range checking.
12121 * ch-tree.h, chill.l: Combine variables range_check and
12122 range_check_disabled into global variable range_checking.
12123 * ch-tree.h: Better definitions of CH_CLASS_IS_VALUE
12124 CH_CLASS_IS_DERIVED.
