3443 (build_process_wrapper): New function (see above).
3444 (build_start_process): Change processing of arguments.
3445 (tasking_setup): Add processing of a different entry point
3446 in case of PROCESSes.
3448 * parse.c (parse_process_definition): Add call to
3449 build_process_wrapper.
3450 * parse.c (end_function): Remove the poplevel() call.
3451 build_process_header no longer makes the corresponding
3454 * grant.c (print_proc_tail): Remove special processing
3455 of PROCESSes, they look now like normal functions.
3457 * decl.c (init_decl_processing): Add declaration of memcmp
3460 * ch-tree.h: Add new prototype for build_process_wrapper,
3461 change prototypes for add_taskstuff_to_list and

3469 * Make-lang.in (CHILL.mostlyclean): Add ch/ch-version.c.
3471 * Makefile.in (CHILL_OBJS): Add ch-version.o. ch-version.c
3472 will get generated every time a new Makefile will get
3474 * Makefile.in (GNUCHILL_VERSION): Remove it, its defined in
3477 * chill.in: In case of -fgrant-only pass "-S -o /dev/null"
3478 to the compiler to avoid generation of an object file.
3480 Thu Sep 8 12:07:28 1994 Per Bothner (bothner@kalessin.cygnus.com)
3482 * convert.c (display_int_cst), ch-tree.h: New function.
3483 * convert.c (digest_array_tuple): Use digest_int_cst to
3484 provide better error messages. Return error_mark_node on error.
3485 * grant.c (decode_const): Simplify by using digest_int_cst.
3486 * grant.c (format_character, find_assoc): Removed.
3488 * decl.c (do_decl): Add missing TREE_CHAIN.
3490 * decl.c (finish_incomplete_decl): Removed.
3491 (init_decl_processing): Don't set incomplete_decl_finalize_hook.
3492 (finish_decl): Remove old C-specific code to deduce size of
3493 array from initialization.
3494 (complete_array_type): Just make it abort.
3496 * except.c (finish_handler_array): Avoid calling C-specific kludge
3497 complete_array_type.
3499 * convert.c (digest_constructor): Rename, and re-write to:
3500 (digest_array_tuple, convert): No longer use the code in
3501 ../c-typeck.c; use a Chill-only implementation (sigh).
3503 * typeck.c (chill_expand_tuple): Remove unneeded call to
3504 complete_array_type.
3506 * expr.c (fold_set_expr), grant.c (decode_constant),
3507 typeck.c (expand_constant_to_buffer): Update name of called
3508 function unpack_set_constructor to get_set_constructor_bits.
3509 * expr.c (powersetlen ): Remove redundant call to convert.
3511 * ch-tree.h (unpack_set_constructor): Removed obsolete declaration.
3513 * inout.c (build_chill_writetext): Handle 64-bit integer literals
3514 by trying to convert them to a smaller type.
3516 * lex.l (convert_number): Always use long long type (possibly
3517 unsigned) to avoid problems with constant folding truncation.
3519 Mon Sep 5 08:08:22 1994 Wilfried Moser (moser@rtl.cygnus.com)
3521 * ch-tree.h (enum chill_built_in_function): Add BUILT_IN_QUEUE_LENGTH.
3522 Add new prototype (see tasking.c).
3524 * expr.c (build_generalized_call): Add processing of
3525 BUILT_IN_QUEUE_LENGTH.
3527 * tasking.c (build_queue_length): New function.
3529 * tasking.c (tasking_init): Add new external function definition.
3531 Thu Sep 1 15:38:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3533 * lex.l (default_lex): New function. Progress towards
3534 getting rid of [f]lex.
3536 * lex.l (convert_number): Use mul_double and add_double.
3537 Set result type to a reasonable type in which the literal
3538 will fit. Give error message if literal is too big.
3540 * lex.l (equal_number): Switch (temporarily) to permanent obstack.
3542 * typeck.c (build_chill_slice_with_range): Check for empty
3543 slice *after* we have checked for upper/lower limit in range.
3545 * grant.c (decode_mode): Remove unused code. (BOOL and
3546 CHAR ranges are represented as INTEGER_TYPEs.)
3548 * tasking.c (build_process_header): Add missing call to
3549 expand_start_bindings.
3550 * parse.c (end_function): Add missing expand_end_bindings.
3552 Wed Aug 31 17:25:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3554 * decl.c (init_decl_processing): Set set_alignment.
3556 Tue Aug 30 16:40:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
3558 * actions.c (print_missing_cases, check_missing_cases,
3559 BITARRAY_TEST, BITARRAY_SET): New functions and macros,
3560 to check for completeness of case actions and expressions.
3561 * decl.c (c_decode_option, init_decl_processing):
3562 Don't set warn_switch.
3563 * expr.c (chill_expand_case_expr): Call check_missing_cases
3564 instead of check_for_full_enumeration_handling.
3565 * parse.c (parse_case_actions): Call check_missing_cases.
3567 * expr.c (build_chill_binary_op): Remove some dead code.
3568 * expr.c (chill_truthvalue_conversion): Call build_chill_binary_op
3569 instead of build_binary_op.
3570 * ch-tree.h (binary_op_error, build_binary_op): Unused. Removed.
3572 * parse.c (end_function): Use kept_level_p in parameter to
3573 poplevel. This reverts a June 13 change.
3575 Fri Aug 26 11:50:19 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3577 * configure: Ignore --without, as ../configure does.
3579 Wed Aug 24 01:17:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3581 * lex.l: Change rule for decimal numbers to allow identifiers
3582 to start with an underscore (_).
3584 Fri Aug 19 16:38:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
3586 * tasking.c (build_receive_signal_case_label): Remove backwards
3587 chill_convert_for_assignment (which converted whatever garbage
3588 was in the *target* to the type of the signal argument!).
3590 Fri Aug 19 07:10:43 1994 Wilfried Moser (moser@rtl.cygnus.com)
3592 * inout.c (build_chill_io_list_type, build_enum_tables),
3593 tasking.c (build_tasking_struct): Temporarily reset
3594 maximum_field_alignment to 0, so that the compiler-built
3595 data structures needed by the RTS can be independent of -fpack.
3597 Thu Aug 18 13:39:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3599 * typeck.c (build_init_struct): Temporarily reset
3600 maximum_field_alignment to 0, so that the compiler-built
3601 data structures needed by the RTS can be independent of -fpack.
3603 Wed Aug 17 23:48:33 1994 Wilfried Moser (moser@rtl.cygnus.com)
3605 * parse.c (parse_primval, expect, parse_on_exception_list):
3606 Print error message only in pass 2.
3608 Wed Aug 17 13:47:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3610 * decl.c (switch_to_pass_2): Revert June 13 change,
3611 (Don't exit after pass 1 if an error was found.)
3613 * ch-tree.def (SLICE_EXPR): New tree-code.
3614 * typeck.c (build_chill_slice): For building a slice of a
3615 bit-string, just generate a SLICE_EXPR.
3616 * decl.c (init_decl_processing): Declare __pscpy.
3617 * actions.c (chill_expand_assignment): Handle a SLICE_EXPR
3618 on the LHS of assignment, by calling __pscpy.
3619 * expr.c (chill_expand_expr): Handle SLICE_EXPR (as a RHS
3620 value) by using __psslice to copy slice to a temp.
3622 Wed Aug 17 05:52:44 1994 Wilfried Moser (moser@rtl.cygnus.com)
3624 * Make-lang.in: Change version of GNUCHILL compiler to 1.4.1.
3625 * expr.c (build_chill_length): Enable LENGTH built-in to process
3626 Buffers and Events too (Z.200/1992).
3627 * lex.l (yywrap): Always set yyin to finput and/or grt_in. On
3628 a linux system the previous version was not able to run.
3629 * tasking.c: Correct processing of infinite buffer- and event-length
3630 to avoid RANGEFAIL warning.
3632 Thu Aug 11 11:46:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3634 * parse.c (parse_if_expression_body): Don't call the C-specific
3635 build_conditional_expr. Just do build_nt (COND_EXPR, ...).
3636 * convert.c (convert): Convert a COND_EXPR by converting
3639 * convert.c (convert): Don't call convert before
3640 convert_to_reference. It's apt to do weird and unneedful things.
3641 * convert.c (convert): If the expression is varying, just call
3642 varying_to_slice, which simplifies quite a bit.
3644 * ch-tree.h (varying_to_slice): Add prototype.
3645 * typeck.c (varying_to_slice): Remove prototype.
3647 * satisfy.c (satisfy): Move case PAREN_EXPR from type 'e'
3650 * except.c (emit_setup_handler): Temporarily reset the
3651 maximum_field_alignment to zero so the compiler's exception
3652 data structures can be compatible with the run-time system,
3653 even when we're compiling with -fpack.
3655 * expr.c (compare_records): Call saved_if_needed on operands.
3657 * expr.c (build_set_expr case NE_EXPR): Don't use __nepowerset
3658 which has been reimplemented to just call __eqpowerset and
3659 invert the result. Inline this new implementation by
3660 handling as EQ_EXPR, and inverting the result.
3661 * decl.c (init_decl_processing): Don't define unused __eqpowerset.
3663 * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
3664 type boolean_type_node, not void_type_node. (Fixing this
3665 avoids a crash in the back-end.)
3667 * grant.c (decode_constant): In a CALL_EXPR, if the argument
3668 list is not a TREE_LIST (as in string repetiation), don't
3671 Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3673 * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
3674 CONST_DECL is from a SET definition. (This is safer than
3675 checking that the type is ENUMERAL_TYPE, because synonym
3676 definitions may have a NULL TREE_TYPE.)
3677 Also, if we have duplicate enums whose types are identical,
3679 * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
3680 an extra 'quiet' parameter, which is true if we're called from
3681 bind_sub_modules. (In that case an error message about duplicated
3682 decls would be repeated later, so suppress it.)
3684 * parse.c (stmt_count): Removed, not used.
3685 (INIT_ACTION): Call emit_line_note only if !ignoring.
3686 (parse_begin_end_block): Do INIT_ACTION even if ignoring.
3688 Fri Aug 5 12:39:11 1994 Per Bothner (bothner@kalessin.cygnus.com)
3690 * parse.c (parse_untyped_expr): Add missing semi-colon.
3692 Thu Aug 4 17:40:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
3694 * parse.c (parse_untyped_expr): Fix various problem for the
3695 case that we see a '(': Add missing 'case' keyword.
3696 Only recurse if '(' is followed by 'if', 'case' or '[',
3697 and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
3699 * parse.c (parse_send_action): Remove extra nreverse.
3701 Thu Jul 28 04:00:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3703 * expr.c (build_allocate_global_memory_call, build_allocate_memory_call):
3706 Tue Jul 26 22:48:15 1994 Michael Tiemann (tiemann@blues.cygnus.com)
3708 * parse.c (parse_untyped_expr): Added missing "case" before LPRN.
3709 Added a missing call to `require' as well.
3711 Tue Jul 19 10:30:12 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3713 * lex.l (yywrap): Define as yywrap_chill to avoid conflicts with
3714 the extern declaration in the flex skeleton.
3716 Mon Jul 18 23:06:04 1994 Per Bothner (bothner@kalessin.cygnus.com)
3718 * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
3719 Check the type of the instance expr using CH_COMPATIBLE,
3720 and not just == instance_type_node. (This allows
3721 the expression to have mode READ INSTANCE).
3722 * tasking.c (build_instance_type): Give instance_type_node
3723 a non-null novelty (i.e. different from a struct).
3724 * tasking.c (build_receive_case_start, build_delay_case_start):
3725 Check that for a location using CH_LOCATION_P.
3727 Mon Jul 18 13:22:23 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
3729 * expr.c (finish_chill_unary_op): Use TREE_SET_CODE not TREE_CODE
3730 to modify a tree code.
3732 Mon Jul 18 11:24:57 1994 Bill Cox (bill@rtl.cygnus.com)
3734 * convert.c (digest_structure_tuple): Fix thinko in TREE_CODE
3737 Mon Jul 18 05:40:15 1994 Doug Evans (dje@canuck.cygnus.com)
3739 * decl.c (warn_bad_function_cast): Define so cc1chill will link.
3741 Thu Jul 14 18:37:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3743 * parse.c (parse_send_action): Do tree_cons *before* checking
3746 Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3748 * convert.c (digest_structure_tuple): Don't use convert to
3749 coerce initial value, use chill_convert_for_assignment instead.
3750 (Thus we also get range_checking.)
3752 * expr.c (build_chill_card): Use force_addr_of instead of
3753 build_chill_addr_expr.
3755 * loop.c (build_temporary_variable): Stylistic tweak.
3756 * loop.c (maybe_make_for_temp): Initialize temp using
3757 explicitly, not using assignment. Avoids a problem if
3758 the expression is read-only.
3759 * typeck.c (smash_dummy_type): Always used the saved TYPE_NAME
3760 and CH_NOVELTY_FLAG.
3762 Wed Jul 6 20:12:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3764 * expr.c, ch-tree.h (finish_chill_unary_op): New function,
3765 based on code ripped out of build_chill_unary_op.
3766 (build_chill_unary_op): Call finish_chill_unary_op unless pass==1.
3767 * satisfy.c (satisfy): Call finish_chill_unary_op when needed.
3769 Mon Jun 27 11:29:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3771 * tree.c (save_if_needed), ch-tree.h: New function.
3772 * typeck.c (build_chill_slice_with_range,
3773 build_chill_slice_with_length): Call save_if_neeed on array arg.
3774 * expr.c (varying_to_slice): Re-write to use save_if_needed.
3776 * typeck.c (extract_constant_from_buffer): Handle BOOLEAN_TYPE.
3778 Mon Jun 27 01:11:10 1994 Wilfried Moser (moser@rtl.cygnus.com)
3780 * inout.c (build_chill_io_list_type): Change layout of __tmp_WIO_list
3781 that it is always the same, regardless if compiled with -fpack
3784 Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3786 * lex.l (yywrap): Kludge to work around mis-synchronization
3787 between lexer (which read ahead) and parser: Don't emit
3788 (left-over) uze_seizefile directives at the end of file.
3790 * typeck.c (build_chill_array_ref): Allow the derived
3791 array indexing syntax for arrays of bit strings.
3792 Add a comment explaining why.
3794 * typeck.c, ch-tree.h (string_assignment_condition): Change
3795 the interface. Return a boolean expression (which can be
3796 used in a conditional at run-time); never expand anything.
3798 * actions.c (chill_convert_for_assignment): Check
3799 string_assignment_condition here, rather than in callers.
3800 * actions.c (chill_expand_assignment): Don't need to check
3801 string_assignment_condition here.
3802 * expr.c (build_chill_function_call): Likewise.
3803 * satisfy.c (safe_satisfy_decl): Update accordingly.
3804 * decl.c (do_decl): Simplify testing and conversion by
3805 deferring everything to chill_convert_for_assignment.
3807 * parse.c: Combine the two variables 'ignore_exprs' and
3808 'ignore_actions' into one variable called 'ignoring'.
3809 * ch-tree.h: Add 'extern int ignoring'.
3810 * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
3811 Rename ignore_actions and ignore_exprs to ignoring.
3812 Remove unneeded extern declarations.
3813 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3814 build_chill_arrow_expr, build_generalized_call, build_delay_action,
3815 build_buffer_type, build_event_type): I changed my mind. It is
3816 cleaner to check for 'ignoring' in the parser, rather than here.
3817 * parse.c (parse_action, parse_primval, parse_opt_mode):
3818 Therefore we must check for ignoring here.
3819 * parse.c (parse_loc_declaration): Set ignoring in pass 2
3820 when parsing the mode.
3822 * tasking.c (generate_tasking_code_variable): Do arithmetic
3823 on signal_code etc using unsigned rather than signed shorts.
3825 * grant.c (static char* current_grant_modename): Removed.
3826 * grant.c (decode_decl case CONST_DECL): Remove error message.
3828 * Make-lang.in (CHILL_SRCS): Add $(srcdir)/ch/parse.c.
3829 * Makefile.in: Fix dependencies for parse.o.
3830 Remove some duplicate dependencies for $(TREE_H).
3832 Mon Jun 13 14:25:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3834 * typeck.c (build_chill_cast): Allow a value cast between
3835 non-discrete object of the same size, but with a pedwarn.
3836 * typeck.c (bit_string_assignment_condition,
3837 char_string_assignment_condition): Merge near-duplicate functions
3838 and place the code in string_assignment_condition.
3840 * decl.c (parm_flag, declare_parm_level, in_param_level_p):
3842 * decl.c (start_chill_function, finish_chill_function): Make
3843 parameter level have same nesting level as body, as required by Z200.
3844 * decl.c (switch_to_pass_2): Always exit if an error has been found.
3845 * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
3846 generated from GRANT ALL.
3847 * decl.c (lookup_name_for_seizing): Don't seize from
3848 the nesting level of builtins (predefined objects).
3849 * decl.c (lookup_name_for_seizing): Make more robust on error.
3851 * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
3852 be 'RESULT' (or 'result'). This makes it more accessible from gdb.
3853 Also, use do_decl to declare it, so that debugging symbols are
3854 generated. And, re-arrange so that actions that need to
3855 be done both passes (such as push_levels) use the same code.
3857 * parse.c (get_type_of): If ignore_exprs, don't lookup name.
3858 * parse.c (end_function): Fix poplevel params.
3859 * parse.c (expect): Don't read forwards on an error.
3860 * parse.c (parse_field): Don't define two tag_list locals!
3861 * parse.c (parse_pass_1_2): Better error message.
3863 * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
3864 parse_opt_mode, rather than vice versa. If parse_opt_mode
3865 returns NULL_EXPR, then parse_mode gives an error.
3866 Change parse_opt_mode (and any functions it calls) to only
3867 return NULL_TREE if there is no mode (even on ignore_exprs).
3868 (parse_set_mode, parse_structure_mode, parse_procedure_mode):
3869 Never return NULL_EXPR.
3870 * tasking.c (build_buffer_type, build_event_type): Return
3871 void_type_node instead of NULL_EXPR if ignore_exprs is true.
3873 * parse.c (parse_synonym_definition): Call parse_untyped_expr
3874 only if we have a mode.
3875 * parse.c (parse_send_action): Parse list of untyped_expr's,
3876 rather than a list of (typed) expressions.
3877 * parse.c (parse_primval): Emit error if '[' seen without
3878 preceding mode name. (If this is to be allowed, call
3879 parse_untyped_expr instead.)
3881 * parse.c (parse_array_index): Renamed to ...
3882 (parse_index_mode): ... to match Z200 terminology.
3883 Re-write to resolve some of the nastier ambiguities,
3884 and allow things like ' CHAR(10) : CHAR(20) '.
3886 * parse.c (parse_tuple_element): Change interface to return
3887 reversed list, so don't call nreverse.
3888 * parse.c (parse_tuple): No longer nreverse element list here.
3889 * parse.c (parse_opt_element_list): Do nreverse here instead.
3890 * parse.c (parse_case_label_list): Call nreverse at end.
3892 Fri Jun 10 15:36:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
3894 * typeck.c (chill_similar): Remove bogus "else".
3896 Wed Jun 8 00:01:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
3898 * ch-tree.h (TYPE_ARRAY_MAX_SIZE): New macro (and comment)
3899 to make it clearer that we are using TYPE_MAX_VALUE in a special way.
3900 * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
3901 * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
3902 * convert.c (convert): When converting a fixed string/array
3903 to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
3904 of (the type of) the padding.
3905 * convert.c (convert): If the concatenation is non-constant, use
3906 the low-level 'build' to set the type of the result (which is usually
3907 a fixed-size array) rather than depend on build_chill_binary_op
3908 to figure it out (it's unable to simplify the size to a constant).
3910 Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
3912 * lang.c (lang_decode_option): Let -fspecial_UC imply
3913 -fno-ignore-case without requiring it explicitly.
3914 * lang.c (lang_decode_option): Support (experimentally)
3915 the -fpack and -fno-pack flags.

3919 * configure: Add support for --program-prefix and --program-suffix.
3921 Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3923 * convert.c (digest_constructor): Check that initial value
3924 is compatible with element mode before calling convert.
3925 * typeck.c (chill_compatible): A string mode is not compatible
3926 with an untyped constructor.
3927 * decl.c (do_decl): Clean up error messages. Use error_with_decl.
3929 * ch-tree.h: Fix inconsistencies: bool_true_node ->
3930 boolean_true_node, and bool_false_node -> boolean_false_node.
3931 * typeck.c (valid_array_index_): Minor simplification.
3933 Tue May 31 04:33:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3935 * inout.c (build_chill_writetext): Add correct processing
3936 of POWERSET RANGE (setmode).
3938 * lex.l (same_file): Add searching for file(s) in
3941 Fri May 27 14:22:42 1994 Per Bothner (bothner@kalessin.cygnus.com)
3943 * Make-lang.c (CHILL.mostlyclean, CHILL.distdir): Don't list
3944 yacc/bison output files, since the grammer is no longer in yacc.
3945 * config-lang.in (diff_excludes): Likewise.
3947 Thu May 26 16:38:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3949 * gperf, hash.h, lex.l, parse.h: Rename PROCESS_TYPE token
3950 (in some files spelled PROCESS_TYPE_ to avoid clashes
3951 with the PROCESS_TYPE tree_code) to PROCESS_TYPE_TOKEN.
3953 Thu May 26 02:18:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3955 * timing.c (build_cycle_start): Change call to __define_timeout.
3956 * decl.c (init_decl_processing): Change definitions of
3957 __define_timeout and __wait_timeout.
3959 Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
3961 Replace yacc-based parser with a recursive-decent parser.
3962 (This may seem backwards, but Chill [like C++] is not a
3963 language that is remotely LALR(1). Using a R-D parser
3964 allows us to use look-ahead and to back-up to resolve the
3965 difficult ambiguities.)
3967 * parse.c, parse.h: New files, containing new r-d parser.
3968 * Makefile.in: Update accordingly.
3969 * actions.c (chill_convert_for_assignment): Don't return
3970 NULL_EXPR if ignore_exprs is true. It simplifies the parser
3971 if we consistently reserve NULL_EXPR for a missing expression.
3972 * expr.c (build_chill_function_call): Likewise.
3974 * lex.l: Tweaks for new parser.
3975 * lex.l (prepare_paren_colon, paren_paren_colon_level,
3976 paren_level): Ugly hack no longer needed.
3978 * expr.c (build_chill_function_call): Cleanup.
3979 Call chill_convert_for_assignment to convert IN/INOUT
3980 paramaters on both input and output. For LOC parameters,
3981 give error if actual is a non-referable location.
3982 * actions.c (convert_for_assignment): Add new parameter (a
3983 "place" string used in error messages).
3984 * actions.c (adjust_parm_or_field): Removed.
3985 * actions.c (chill_expand_assignment): Take just a single LHS,
3986 and move support for multiple assignments to ...
3987 (expand_assignment_action): ... here. Some cleaning up.
3988 * timing.c (build_cycle_start): Adjust accordingly.
3989 * actions.c (expand_assignment_to_varying_array): Likewise.
3990 * tasking.c (many places): Ditto.
3991 * ch-tree.h: Fix declarations appropriately.
3993 * parse.c (parse_defining_occurrence_list): Return a single
3994 IDENTIFIER_NODE (instead of a singleton list) in the common
3995 case. Minor complication to save a minor amount of space.
3996 * decl.c (do_based_decls): Move guts of code into ...
3997 (do_based_decl): ... this new function.
3998 * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
3999 * decl.c (push_syndecl): Replace by ...
4000 (push_syndecl): ... (which only supports a single name).
4001 (push_modedef): Only handle a single name.
4002 * tasking.c (build_process_header, build_signal_struct_type):
4005 * expr.c (build_generalized_call): Handle string repetition.
4006 * expr.c (build_chill_repetition_op): Change interface.
4007 * grant.c (decode_constant): Allow parameter list to be
4008 a non-TREE_LIST. (Used for string repetition.)
4010 Wed May 25 11:28:48 1994 Per Bothner (bothner@kalessin.cygnus.com)
4012 * lex.l (make_identifier): Replaced by ...
4013 (read_identifier, handle_name): ... new functions.
4014 * lex.l: Parse an identifiers using read_identifier using
4015 read_identifier and handle_name, rather than having [f]lex
4016 do it. (One reason is that lex uses a fixed-size buffer.)
4018 * lex.l (read_directive, skip_directive): New functions.
4019 Use them to parse compiler-directives, instead of rather
4020 ugly and useless use of lexer start conditions.
4022 Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4024 * decl.c (unnamed_module_number): Renamed to ...
4025 (module_number): .. and make non-static.
4026 (push_module): Always increment module_number.
4027 * lex.l (yywrap): Print warning if no modules seen.
4029 * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
4030 decl to current_seizefile_name (which is unreliable).
4031 * grant.c (chill_grant): Set it here instead.
4033 * expr.c (fold_set_expr): Use int_size_in_bytes instead of
4034 TYPE_PRECISION (which is not defined for a SET_TYPE).
4036 Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
4038 Cleanup to remove need for variables in common storage.
4039 * decl.c: Remove unused use of current_obstack.
4040 * actions.c (maybe_chill_check_decl): Remove unused function.
4041 * actions.h, lang.c: Remove uses of doing_chill_thang.
4042 * ch-tree.h (void_list_node): Make extern (rather than common).
4043 * decl.c (void_list_node): Add definition.
4045 Thu May 19 06:54:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
4047 * configure (build): Build canon_host and canon_target
4048 to pass it to all subsequently generated Makefiles (needed
4049 for testsuite/execute in case of cross build).
4051 Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4053 * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
4054 the input type, which loses with the no-longer-new 2-pass
4055 implementation, since the input "type" could be an IDENTIFIER_NODE.
4056 * grant.c (raw_decode_mode): Rename to decode_mode.
4058 Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
4060 * typeck.c (chill_location): Neither a STRING_CST nor a
4061 CONSTRUCTOR is a location.
4062 * typeck.c (chill_root_mode): Convert a function to a
4063 pointer-to-function.
4064 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
4065 build_chill_arrow_expr): If ignore_exprs, return operand
4066 rather than NULL_EXPR. This makes it easier for the parser to
4067 distinguish missing expressions.
4068 * expr.c (build_max_min): Convert the lower bound of a
4069 set to a long before calling run-time routine.
4070 * expr.c (build_chill_pred_or_succ): Use discrete_type_p
4071 to check the argument type.
4072 * expr.c (build_chill_arrow_expr): If argument is not a location,
4073 do a predwarn if it is a STRING_CST or has function type.
4075 Tue May 17 06:05:13 1994 Wilfried Moser (moser@rtl.cygnus.com)
4077 * configure (build): Remove building of canon_host and canon_target.
4078 It doesn't work in any case.
4080 Mon May 16 02:10:35 1994 Wilfried Moser (moser@rtl.cygnus.com)
4082 * configure (build): Build canon_host and canon_target
4083 to pass it to all subsequently generated Makefiles (needed
4084 for testsuite/execute in case of cross build).
4085 * Make-lang.in (chill-runtime): Change chill to CHILL in the case
4086 statement to build chill-runtime automatically.
4088 Mon May 9 15:30:08 1994 Doug Evans (dje@canuck.cygnus.com)
4090 * Makefile.in (FLAGS_TO_PASS): Define.
4092 (../cc1chill): Depend on $(OBJDEPS) $(C_OBJS).
4093 * Make-lang.in (cc1chill): Delete dependency on $(OBJS) $(BC_OBJS).
4094 (CHILL.mostlyclean): Use `mostlyclean' as recursive target.
4096 Sun May 8 13:05:00 1994 Per Bothner (bothner@cygnus.com)
4098 * Make-lang.in (cc1chill): Should not depend on libgcc.a.
4100 Thu May 5 18:58:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
4102 * decl.c (copy_lang_decl): New (dummy) function.
4104 Mon May 2 14:33:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
4106 * parse.y (sendaction): Fix thinko (in sense of condition).
4107 * tasking.c (build_receive_case_label): Another thinko.
4109 * parse.y (optsigdest): Force ignore_exprs to 0 while parsing
4112 * decl.c (build_chill_function_type): Don't call layout_type
4113 (since that may prevent parameter or result types being
4114 properly satisfied).
4115 * satisfy.c (satisfy): Layout FUNCTION_TYPEs.
4116 * parse.y (procmode): Call build_chill_pointer_type, rather
4117 than build_pointer_type (which incorrectly sets TYPE_SIZE).
4119 * parse.y (get_type_of): Handle TYPE_DECL (again).
4120 * parse.y (optresultspec): Call build_chill_reference_type, rather
4121 than build_reference_type (which incorrectly sets TYPE_SIZE).
4122 * parse.y (range_or_mode): Rename to plain range, since it
4123 no longer matches modename.
4124 * actions.c (chill_handle_case_label_range): New function, with
4125 functionality moved out of chill_handle_case_label.
4126 * actions.c (chill_handle_case_label): Handle here the case that
4127 the label_value is a TYPE_DECL (modename). Also clean up some.
4128 * typeck.c (build_chill_slice_with_length): Convert max_index
4129 to the type of min_value. (Old code broke on varying strings.)
4131 Sun May 1 13:53:36 1994 Doug Evans (dje@canuck.cygnus.com)
4133 * Makefile.in (BC_OBJS): Delete all references
4134 (OBJS): Cat ../stamp-objlist to get language independent files.
4135 (../cc1chill): Delete dependency on $(OBJS).
4136 * Make-lang.in (cc1chill): Depend on stamp-objlist.
4138 Sat Apr 30 14:50:15 1994 Per Bothner (bothner@kalessin.cygnus.com)
4140 * lex.h, lex.c: Remove lastiddecl.
4141 * lex.l (name_type_signal): Simplify. We no longer check for
4142 TYPENAME or SIGNALNAME (which was unreliable with two passes).
4143 Also rename to make_identifier.
4144 * parse.y: Cleaned up grammar to not need SIGNALNAME or TYPENAME.
4145 * Makefile.in (stamp-parse); One conflict fewer!
4146 * parse.y (rccase_label_flag): Moved to tasking.c.
4147 * parse.y (rccase_label): Move most of the logic to
4148 build_receive_case_label in tasking.c.
4149 * parse.y (sendaction): Re-write to not depend on SIGNALNAME.
4151 * parse.y (name): Do name lookup here (and not in location).
4152 * parse.y: Replace most uses of NAME by higher-level non-terminals:
4153 simple_name_string, name_string, defining_occurrence, or name.
4155 * tasking.c (build_receive_signal_case_label,
4156 build_receive_buffer_case_label): New functions, split out from
4157 build_receive_case_label.
4158 * tasking.c (build_receive_case_label): Change parameters
4159 and return type. Moved stuff here (from the parser).
4160 * tasking.c (struct rc_state_type): Removed had_errors.
4161 Return error_mark_node instead.
4162 * tasking.c (build_rccase_set_error), ch-tree.h: Removed.
4164 * expr.c (build_generalized_call): If func is a signal type,
4165 call build_signal_descriptor.
4167 * parse.y (arrayindex): Renamed to index_mode, to match Z.200.
4168 * parse.y (ioindexmode): Removed; use index_mode instead.
4169 * expr.c (build_generalized_call): If args is a RANGE_EXPR,
4170 we have either a slice or a range mode, depending on func.
4171 * parse.y (index_mode): If we got an 'expr', only allow a name,
4173 * parse.y (call): A slice with both end points can be a range
4174 mode, so defer handling to build_generalized_call (or index_mode).
4176 * typeck.c (build_chill_slice_with_length): Fix type-checking.
4177 * typeck.c (chill_novelty): Undo (part of) change of April 28:
4178 The novelty of a range mode is the novlety of the parent.
4179 * typeck.c (chill_root_mode): Don't return integer_type_node
4180 if argument has non-nil novelty.
4182 * decl.c (global_bindings_p): Return -1 as true, for the sake
4183 of variable_size (in ../stor-layout.c).
4185 Fri Apr 29 13:42:43 1994 Per Bothner (bothner@kalessin.cygnus.com)
4187 * parse.y: Remove TYPENAME and modename. These are now plain
4188 NAMEs. Modify parsing actions appropriately.
4189 * expr.c (build_generalized_call): Handle the case that
4190 TREE_CODE (func) == TYPE_DECL (as in a cast).
4191 * lex.l (name_type_signal): Never return TYPENAME.
4192 * parse.y (get_type_of): If pass 1, just return the argument.
4194 * decl.c (do_decl): If an initializer has the wrong type,
4195 replace it by NULL_TREE, to avoid subsequent errors.
4197 Thu Apr 28 15:21:56 1994 Wilfried Moser (moser@rtl.cygnus.com)

4230 call one of the above mentioned functions.
4231 * tasking.c (build_delay_case_start, build_delay_case_label,
4232 build_delay_case_end): Rewritten due to new implementation of events.
4233 * tasking.c (build_delay_action): Rewritten due to new implementation
4235 * tasking.c (expand_send_buffer), ch-tree.h: New function.
4236 * timing.c (build_at_action, build_cycle_start, build_cycle_end),

4241 * typeck.c (smash_dummy_type): Handle the special case of a
4242 NEWMODE of a range mode, as required by Z200, by creating a
4243 new parent mode with the new novelty (and casting the min
4244 and max of the range to teh new parent mode).
4245 * typeck.c (chill_novelty, chill_root_mode): Remove special
4246 kludges for of NEWMODE ranges.
4247 * expr.c (build_chill_lower_or_upper): New function, combining
4248 the "guts" of build_chill_lower and build_chill_upper.

4250 need to kludge the novelties.
4252 * typeck.c (valid_array_index_p): A string index expression
4253 need not be Compatible with the index type; only similar.
4255 * decl.c (layout_chill_variants): If error seen, skip stuff
4256 (rather than aborting or crashing).
4257 * decl (push_modedef): If newdecl's type is an error mark,
4258 continue rather than aborting.

4262 * Make-lang.in: Update of directory reorg from fsf.
4263 * config-lang.in: Ditto.

4267 * typeck.c (chill_similar): Check RECORD_TYPEs properly,
4268 * convert.c (convert): If all else fails, just call convert1.
4269 Thus we can now convert RECORD_TYPEs (assuming they are similar).
4271 * parse.y, lex.l: Remove BUFFERNAME (use location/expr instead).

4279 * parse.y (modename): No longer match SIGNALNAME. Instead, add it
4280 to name and simple_name_string. This removes a reduce/reduce conflict.
4281 * Makefile.in (stamp-parse): Expect fewer conlicts.
4283 * lex.l (yywrap): Move check for circularly seizeing current
4284 grant-file from here ...
4285 * lex.l (handle_use_seizefile_directive): ... to here.
4286 This is to avoid calling stat on a not-yet written grantfile,
4287 now that we're using same_file (which calls stat).
4288 * grant.c (set_use_this_gf): Removed.
4289 * grant.c (set_default_grant_file): Set grant_file_name here,
4290 because we need it earlier (due to above lexer change).
4292 * typeck.c (layout_chill_struct_type): Remove useless code to
4293 remove zero-width bitfield (which messes up CONST_DECLs).
4295 Sat Apr 23 13:16:39 1994 Bill Cox (bill@rtl.cygnus.com)
4297 * Makefile.in (check): Assure that 'ld' is available before checking.

4338 * Makefile.in (check): Simplified regression.sh call.
4339 * regression.sh: Change command-line parsing. Default
4340 srcdir to the script's path. Calculate objdir
4341 internally - don't pass it in.

4386 * actions.c (chill_expand_assignment): Check for compatibility
4387 _after_ "expanding out" a binary operation. This fixes
4388 the case "STRING //:= CHAR".
4390 * lex.l (equal_number): Convert symbol to integer_type_node, to
4391 force the value to be INT-derived (and avoid novelty conflicts).

4493 Clean up error message for OUT//INOUT not location to use only 1 line.
4494 Add error message for OUT/INOUT if type is READonly.
4495 * typeck.c (build_chill_modify_expr): Simplify.
4497 Sun Mar 27 19:30:25 1994 Bill Cox (bill@rtl.cygnus.com)
4499 * Makefile.in: Clean up generally. Assure that

4531 Wed Mar 23 13:34:18 1994 Bill Cox (bill@rtl.cygnus.com)
4533 * expr.c (build_generalized_call): Revert previous change.
4534 To do this correctly, we need a new parsing mechanism, and

4556 * configure: Generate better .gdbinit files.
4558 Tue Mar 22 11:59:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
4560 * actions.c (check_range): Don't emit dynamic checks
4561 if not current_function_decl.

4564 at semantic level if not the NAME of a type).
4565 * typeck.c (build_chill_cast): Re-enable some casts.
4566 * satisfy.c (safe_satisfy_decl): Remove redundant CONST check.

4583 string assignment case.
4584 * expr.c (chill_expand_expr): Now that we're using build_chill_function_call,

4586 type explicitly. Do that.
4587 * satisfy.c (safe_satisfy_decl): Correct range-checking code.
4589 Mon Mar 21 16:25:07 1994 Bill Cox (bill@rtl.cygnus.com)

4599 * typeck.c (layout_chill_range_type): Instead of tree_int_cst_lt
4600 use compare_int_csts (which is more robust when signedness differs).

4604 * expr.c (chill_expand_expr): Code to expand SET_IN_EXPR,

4606 conversions (because we're now using build_chill_function-call).
4607 * actions.c, decl.c, expr.c, grant.c, parse.y, typeck.c:
4608 Use SET_IN_EXPR in place of IN_EXPR.
4610 * expr.c (build_compare_discrete_expr), ch-tree.h: New function,
4611 with code moved from build_compare_expr.
4612 * expr.c (build_compare_expr): Re-enable compatibility test.

4639 to be compatible with the N-value class, with suitable M and N.
4640 * typeck.c (build_chill_slice): Don't smash a void TREE_TYPE.

4643 * expr.c (build_compare_expr): Fix thinko. Add save_exprs.
4645 * expr.c (build_compare_expr): Fix a transcription bug
4646 (for converting NULL INSTANCEs). Also #include convert.h.

4649 Works even if their types have different TREE_UNSIGNED.
4650 * expr.c (finish_chill_binary_op): Moved code dealing with
4651 the comparison operators from here ...
4652 * expr.c (build_compare_expr): ... to new function here.

4677 to have consistent operand types.
4678 * typeck.c (valid_array_index_p): Change interface to pass
4679 validity conditions back on caller's TREE_LIST. We
4680 cannot link the conditions to anything which a
4681 layout_type routine will expand, since that will occur
4682 before the exception handler is set up.
4683 Change calls to valid_array_index_p also.
4685 Fri Mar 18 14:40:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
4687 * actions.c, except.c, loop.c, tasking.c: Call

4691 * loop.c (top_loop_end_check): Coerce library function arg.
4692 * convert.c, expr.c: Re-write to avoid calls to C-specific
4693 function build_unary_op (e.g. by calling build1 directly).
4695 * typeck.c (chill_equivalent): Change to force failure
4696 for non-matching integral types (even if not ranges).
4698 * typeck.c, ch-tree.h (build_chill_slice): Make non-static.
4699 * expr.c (varying_to_slice): Call build_chill_slice (and not
4700 build_chill_slice_with_length, which does bunches of range
4701 checking and does not allow the length to be zero).
4702 * convert.c (convert): Fix off-by-one error.
4703 * actions.c (chill_expand_array_assignment): Minor cleaning up.

4708 take *two* pointer parameters, not one.

4711 * typeck.c (build_chill_slice_with_length): Fix Bill's previous fix.

4722 * typeck.c (build_chill_slice), expr.c (chill_expand_expr
4723 [case CONCAT_EXPR]): Remove kludge setting slice size upper bound
4724 in TYPE_LANG_SPECIFIC, and restore kludge setting it in MAX_VALUE.
4725 * typeck.c (build_chill_slice): Use TYPE_MAX_VALUE of
4726 array_type if needed for size upper bound of slice_type.
4727 * expr.c (build_concat_expr): Improve calculation of size upper bound.
4729 * typeck.c (valid_array_index_p): Check compatibility using
4731 * typeck.c (build_chill_slice_with_length); For now revert
4732 calling valid_array_index_p on length. (It makes it harder
4733 to realize when the slice is constant length.)
4734 * expr.c (build_chill_indirect_expr): Minor tweak. (This
4735 seems to work around a weird C compiler bug. ??)
4737 * expr.c (build_chill_function_call): Cleanup so it doesn't
4738 call build_function_call (in c-typeck.c).
4739 * typeck.c, expr.c: Use build_chill_function_call instead of
4740 build_function_call (in c-typeck.c).
4742 * parse.y (discrete_mode): Move some of the rules from
4743 non_array_mode into new non-terminal.
4744 (arrayindex): Use discrete_mode (with NAME and TYPENAME) to

4747 * convert.c (digest_structure_tuple): Add missing parameter.
4748 * decl.c (comptypes): Remove unused prototype.
4749 * decl.c (build_chill_function_type): Handle NULL return_type
4750 correctly (convert to void_type_node).
4751 * decl.c (init_decl_processing): layout boolean_type_node *after*
4752 we've set it's TYPE_MIN_VALUE and TYPE_MAX_VALUE.
4754 Wed Mar 16 16:08:22 1994 Bill Cox (bill@rtl.cygnus.com)

4757 * convert.c (convert): Correct calculation of padding length.
4758 * decl.c (grok_chill_fixedfields): Move ignore_exprs test to
4759 parse.y where it belongs. This permits the removal of a kludge
4760 in make_process_struct.

4762 code to output error in only one pass.

4773 * ch-tree.h: Fix prototype for valid_array_index_p.
4774 * expr.c (chill_expand_expr): Call build_chill_array_ref to get
4776 (build_hill_lower, build_chill_upper): Return value now inherits
4777 the novelty of the input parameter.
4778 (varying_to_slice): Use CH_NOVELTY macro rather than calling
4779 chill_novelty directly.
4780 * grant.c (newstring): Make len unsigned and cast xmalloc parameter
4782 (print_integer_type): Pass string value as APPEND's second parameter.
4783 (decode_decl): Pass a boolean expression as print_proc_tail's
4785 (chill_finish_module_code): Make xmalloc's parameter unsigned.
4786 * lex.l: Pass sizes to xmalloc as unsigned ints. Pass second
4787 parameter to in_word_set as unsigned.
4788 * loop.c (build_loop_start): Check top_loop_end_check return value.
4789 * parse.y: Add casts to int for third do_decls parameter, fifth
4790 build_loop_iterator parameter, etc.
4791 * tasking.c (build_receive_case_end): Chack cond_stack before popping.
4792 * typeck.c (validate_varying_array_ref, chill_max_vary_array_index,
4793 valid_array_index): Delete them. They're now unused.
4794 (valid_array_index_p): Add function, call it everywhere that an
4795 array index is checked.
4796 (build_chill_slice): Restore old functionality where varying_to_slice
4797 is called to handle slices of varying arrays, rather than handling
4799 (build_chill_slice_with_range, build_chill_slice_with_length):
4800 Check range limits for TREE_CONST before calling tree_int_cst_lt.
4801 Delete now-obsolete checks of constant indices.
4803 Mon Mar 14 17:26:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4805 * parse.y (modeless_expr): New rule to allow ([...]) and (if...)
4806 to count as untyped_exprs. (This is not really permitted by the
4807 Blue Book, but has been requested by customers.)
4809 Thu Mar 10 10:11:02 1994 Bill Cox (bill@rtl.cygnus.com)
4811 * chill.texi: Document new command-line options.
4812 * expr.c (build_chill_num): Set unsigned parameter for

5013 Wed Feb 23 15:07:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
5015 New cleaner solution to the following problem:
5016 Chill allows an action to be followed by an ON-handler.
5017 But we don't know if an action has a handler until we've parsed
5018 its end, yet we want to generate extra code to set up an
5019 exception handling contour only if needed. The old solution
5020 would generate code for the action into an rtl sequence, and then
5021 splice in the exception-setup code if we later found we needed it.
5022 This has a few problems (for example it confuses the management
5023 of stack temporaries), and is ugly. Now that the compiler is 2-pass
5024 we have a cleaner solution: In pass 1, we remember which actions
5025 were followed by ON-handlers. In pass 2, we use this information
5026 to generate appropriate code before an action.
5027 * except.c (push_handler, pop_handler): In pass 1, set up data
5028 structures (global_handler_list) to remember if an action has an
5029 ON-handler. In pass 2, digest this information, and setup
5031 * except.c, actions.h (pop_handler): Take an extra int arg.
5032 * except.c (emit_setup_handler): New function, with code (moved
5033 from chill_start_on) to emit code before an action that has a handler.
5034 * except.c (except_init_pass_2): New function.
5035 * parse.y (pass1_2): Call except_init_pass_2 before pass 2.
5036 * parse.y (POP_UNUSED_ON_CONTEXT): Don't call pop_sequence.
5037 * parse.y: Invoke POP_UNUSED_ON_CONTEXT and POP_USED_ON_CONTEXT
5038 in pass 1 as well as pass 2.
5039 * parse.y (BEGIN ... END): Re-arrange logic to avoid block_stack
5040 (local to ../stmt.c) getting out of sync.
5041 * actions.c (push_action): Don't need to emit a NOP,
5042 now that we're no longer moving sequences around.
5043 * actions.c (push_action): Call push_handler even in pass one.

5790 * ch-expr.c (build_chill_indirect_ref): Handle MODE == NULL_TREE.
5792 * ch-expr.c (fold_set_expr): Handle OP1 == NULL_TREE (which happens
5793 for unary set operations).
5795 * ch-expr.c (build_chill_array_expr): Take new argument FORCE. All
5796 callers changed. All callers changed.
5798 * ch-convert.c (digest_structure_tuple): Handle SELECTED_VARIANT
5799 being NULL_TREE until we've started walking the list of values via
5800 the loop over VARIANTs.
5802 * ch-parse.y (build_chill_constructor): If we see an IDENTIFIER_NODE,
5803 treat it as an enum value (and hence constant). Also, only set
5804 TREE_STATIC if the constructor is indeed constant.
5805 * c-typeck.c (chill_initializer_constant_valid_p): If we see a
5806 VAR_DECL, test the TREE_CONSTANT field of the DECL_INITIAL, don't
5807 recurse on the DECL_INITIAL.
5809 Wed Jan 5 01:24:50 1994 Bill Cox (bill@cygnus.com)
5811 * Makefile.in: Add CHILL to LANGUAGES variable.
5812 * ch-actions.c (check_range): Call build_binary_op instead of
5813 fold, build to get the common types chosen.
5814 (cond_range_exception, cond_overflow_exception,
5815 cond_type_range_exception): Delete, obsolete.
5816 (chill_convert_for_assignment): Enable this, get particular
5817 about when to generate rangecheck code.
5818 * ch-expr.c (build_chill_function_call): Sketch in where to
5819 perform chill_convert_for_assignment on actual parameters.
5820 (build_chill_addr_expr): Correct compiler warning.
5821 * ch-loop.c (build_chill_iterator): Add runtime check for
5822 negative loop step expression.
5823 * ch-tree.h: Add prototype.
5824 * ch-typeck.c (chill_max_vary_array_ref): Correct misunderstanding.
5825 A varying array's length field counts the NUMBER of active array
5826 array entries, not the byte-length of them.
5828 Tue Jan 4 17:57:39 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5830 * ch-decl.c (do_decl): Call `suspend_momenary' if the
5831 converted constructor must live on the permanent_obstack.
5832 * ch-convert.c (convert): When building a new SET_TYPE
5833 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5834 * c-typeck.c (chill_initializer_constant_valid_p): Handle VAR_DECLs.
5836 * ch-typeck.c (chill_location): CONSTRUCTORS that are static
5838 * ch-satisfy.c (safe_satisfy_decl): Convert DECL_INITIAL of CONST_DECL
5839 on permanent_obstack if necessary.
5841 * ch-convert.c (digest_structure_tuple): When building a new SET_TYPE
5842 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5844 * ch-decl.c (do_decl): Fix handling of REFERENCE_TYPEs which
5845 the patch below helped to mess up.
5847 * ch-expr.c (build_chill_arrow_expr): Call `mark_addressable'.
5848 (build_chill_addr_expr): Take new argument ERRORMSG.
5849 All callers changed. Also, call `build_chill_addr_expr' where
5850 we used to call `build1 (ADDR_EXPR, ptr_type_node, ...)' since
5851 that now calls `mark_addressable' automagically.
5853 * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.
5854 This is needed because variables may appear in initialization
5855 statements, and their DECL_INITIALs are their values at
5856 initialization time.
5857 * ch-convert.c (digest_structure_tuple,digest_constructor): Changed
5858 to handle VAR_DECLs as initializers.
5860 * ch-convert.c (digest_structure_tuple): Copy elements of INITS so
5861 they aren't destroyed for later use.
5863 Tue Jan 4 15:25:30 1994 Bill Cox (bill@cygnus.com)
5865 * ch-expr.c (chill_expand_expr): Correct check-range lo_limit
5866 parameter for varying_array_ref calculations.
5867 (build_chill_indirect_ref): Prevent seg fault due to syntax error.
5868 * ch-typeck.c (build_chill_slice_with_range): Correct issuance
5869 of bogus error in votrics.
5870 (build_chill_slice_with_length): Change for debug tracability.

5874 * ch-convert.c (digest_structure_tuple): Fix phasing problem in
5875 handling variant record initializers.
5876 (various places): Change `pop_init_level' calls to match
5877 `push_init_level' wrt implicit variable.
5879 * ch-typeck.c (build_chill_slice): Convert the dynamic max index to
5880 `integer_type_node' before using it in comparisons. FIXME: should
5881 this be done in `chill_max_vary_array_index' by default?
5883 Tue Jan 4 00:24:14 1994 Bill Cox (bill@cygnus.com)
5885 * ch-actions.c: Fix comments.
5886 * ch-parse.y: Define caseaction_flag.
5887 (caseaction): Create new caseaction_flag node at the start,
5888 then free it at the end. Check it before the ELSE code.
5889 (expanded_case_label): Check the flag here. If set in either
5890 place, generate a jump to the end of the case.
5891 * ch-typeck.c (build_chill_slice_with_length,
5892 build_chill_slice_with_range): Add lots of compile-time
5893 parameter range checking.
5895 Mon Jan 3 21:49:04 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5897 * ch-convert.c (digest_structure_tuple): Call `push_init_level' with
5898 implicit==0 everywhere, not 1.
5899 (digest_constructor): Ditto.
5901 * ch-actions.c (check_range): Permit limits to be NULL_TREE.
5902 Also, hack out some dead code.
5903 * ch-typeck.c (build_chill_slice): Check varying and non-varying
5904 slice constructs for range failures.
5905 (build_chill_slice_with_range): Reindented, but not changed.
5907 * ch-typeck.c (chill_max_vary_array_index): New function.
5908 * ch-expr.c (chill_expand_expr): Call it.
5910 * ch-decl.c (var_data_id, var_length_id): New variables.
5911 (init_decl_processing): Initialize them. All calls to
5912 get_identifier (VAR_LENGTH or VAR_DATA) are now replaced
5913 by references to these variables. This simplifies the code
5914 w/o obscuring anything.
5916 Mon Jan 3 21:24:44 1994 Bill Cox (bill@cygnus.com)
5918 * c-typeck.c: Fix comment.
5919 * ch-actions.c (chill_expand_assignment): Error assigning to
5920 READONLY location. (PR_3903) Pass filename, linenumber
5921 to setbitpowerset runtime routine.
5922 * ch-decl.c (init_decl_processing): Add filename, linenumber
5923 parameters to setbitpowerset prototype.
5924 * ch-expr.c (build_chill_function_call): Error when passing a
5925 READonly location as a LOC or INOUT parameter.
5926 * ch-parse.y (mode): Correct code marking type as readonly.
5928 Mon Jan 3 19:03:55 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5930 * ch-actions.c (chill_expand_assignment): Disable code that defeats
5931 building varying array references.
5932 * ch-expr.c (chill_expand_expr): Add rangecheck code to
5933 VARY_ARRAY_REF case.
5934 * ch-typeck.c (build_chill_array_ref): Don't call an `expand_'
5935 function (in this case, `validate_varying_array_ref') when we're
5936 doing a `build_' operation.
5938 * ch-typeck.c (validate_varying_array_ref): Simplify interface
5939 since INDEX parameter can never meaningfully be an INDEXLIST.
5940 * ch-actions.c (expand_varying_length_assignment): Caller changed.
5942 Mon Jan 3 07:29:45 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5944 * ch-typeck.c (build_chill_cast): Set TREE_CONSTANT on NOP_EXPRs.
5945 * ch-convert.c (digest_structure_tuple): Switch to permanent_obstack
5946 if we need to build a CONSTRUCTOR for a SET_TYPE initializer.
5947 (digest_structure_tuple): If TREE_VALUE (VALUE) == NULL_TREE, don't
5948 call CH_COMPATIBLE or try to convert it to TREE_TYPE (FIELD). This
5949 can happen when constructors are output incrementally.
5950 * c-typeck.c (initializer_constant_valid_p): Handle SET_TYPEs.
5951 * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
5954 Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5956 * ch-convert (digest_structure_tuple): Handle SET_TYPEs. Also, call
5957 `convert' so we can handle INSTANCE types (and other anomolies)
5960 * ch-convert.c (digest_structure_tuple): Fixed variant
5961 structure initialization. Also fixed a typo (TYPE_NAME
5962 was being used on a FIELD_DECL instead of DECL_NAME).
5963 * c-typeck.c (initializer_constant_valid_p): Pass missing
5964 ENDTYPE argument on recursive call.
5965 (set_init_field): New function, needed by ch-convert.c change above.
5967 * ch-decl.c (layout_chill_variants): Added a FIXME next to an
5968 almost certain typo.
5970 * ch-expr.c (build_chill_arrow_expr): Call `build1' and set
5971 TREE_CONSTANT for static references.
5972 * ch-except.c (chill_start_on): Change calls to
5973 `build_unary_op' (which is C-specific) to `build_chill_arrow_expr'
5974 which has CHILL semantics.
5975 * ch-convert.c (convert): Ditto (albeit in some disabled code).
5977 Sat Jan 1 21:26:43 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5979 * ch-satisfy.c (safe_satisfy_decl): Reorder conditional test of
5980 TREE_CODE of DECL in case it's altered by actions in the switch.
5982 * ch-satisfy.c (satisfy): Undo abort added earlier on 1 Jan. CVS log
5983 mentions where to find code that triggers this case.
5985 * ch-actions.c (adjust_parm_or_field): Handle CONSTRUCTORS here as
5988 * ch-convert.c (digest_structure_tuple): Push to permanent_obstack if
5989 we're dealing with a CONSTRUCTOR that is TREE_PERMANENT.
5990 (digest_constructor): Ditto.
5992 Sat Jan 1 10:29:19 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5994 * ch-parse.y (handleraction,resultaction,assignaction,call): Modified
5995 so that CONSTRUCTORS are properly handled before being used.
5997 * ch-convert.c (chill_start_init): New function. All callers to
5998 `start_init' changed to call this function instead.
5999 (digest_struct_tuple): Defend against initialization machinery
6000 mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
6001 IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
6002 needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
6003 can be refered to throughout the compilation unit. Also remove an
6004 extraneous call to `process_init_element' erroneously added to the
6005 variant record sub-loop.
6006 (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
6007 CONSTRUCTORS of SET_TYPE.
6008 * ch-parse.y (build_chill_constructor): Refix typo. Also set
6009 TREE_STATIC if at top level.
6011 * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
6012 TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
6013 should have been called.
6015 * ch-convert.c (digest_struct_tuple): Restore code which tracks
6016 field initializations so that the compiler can deduce what variant
6017 initializations to assume.
6019 * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
6020 when we push into a scope that has a DECL with a CONSTRUCTOR as its
6023 * ch-parse.y (build_chill_constructor): Change the name of the
6024 parameter to something more meaningful. Fix typo. Also, handle case
6025 where element is an untyped CONSTRUCTOR.
6027 * ch-except.c (finish_handler_array): Set TREE_CONSTANT on
6028 constant ADDR_EXPRs.
6029 (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT
6030 on JBUF_REF (instead of calling `build1' which does not).
6032 * ch-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
6034 * ch-typeck.c (chill_expand_tuple): Deleted.
6035 * ch-parse.y (primval rule): Don't call `chill_expand_tuple';
6036 instead, use initialization machinery for CONSTRUCTORS that
6038 * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
6039 that are created here.
6040 * ch-satisfy (satisfy): Abort in case we would have called
6041 chill_expand_tuple. FIXME: some other code is needed here,
6042 but I don't know what yet.
6044 * ch-parse.y (build_chill_constructor): New function to
6045 propagate TREE_CONSTANT bits to CONSTRUCTORS.
6046 (untyped_expr rule): Use it.
6047 (primval rule): Use it.
6049 * ch-decl.c (do_decl): Call `finish_init'.
6050 * ch-convert.c (convert): If we spontaneously create a CONSTRUCTOR in
6051 this function, make sure the initialization machinery is set up.
6053 * ch-convert.c (digest_structure_tuple, digest_constructor): Add
6056 Fri Dec 31 11:31:01 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6058 * ch-grant.c (chill_finish_module_code): Mark ADDR_EXPR built by hand
6059 as being TREE_CONSTANT. Otherwise it gets bounded by the initializer
6062 * ch-decl.c (do_decl): Change in CONSTRUCTOR handling due to...
6063 * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
6064 rewritten to work with GCC's initialization code. The basic change
6065 was to keep the initializers in sync with the initialization
6066 machinery that `process_init_element' imposes. Both of these
6067 functions now return `void'.
6068 * ch-convert.c (convert): Changed calls to `digest_...' functions.
6070 FIXME: the code handling UNION_TYPE (and variant records) has not
6073 Fri Dec 31 15:32:56 1993 Bill Cox (bill@rtl.cygnus.com)
6075 * ch-lex.l (convert_number): Output the converted number if
6077 * ch-parse.y (signaldef): Set ignore_exprs correctly for a
6080 Fri Dec 31 13:17:48 1993 Bill Cox (bill@cygnus.com)
6082 * ch-parse.y: Cleanup handling of RETURN actions, to distinguish
6083 a RETURN without a value (which cannot have an exception
6084 handler) from a RETURN with a value (which can). Eliminate
6085 some shift/reduce and reduce/reduce conflicts.
6087 Thu Dec 30 17:42:32 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6089 * ch-inout.c (build_chill_writetext): Deal with 2 cases where
6090 types returned from `type_for_size' are not expected. FIXME.
6091 * ch-decl.c (init_decl_processing): Mark `char_type_node' unsigned.
6092 This is required when range checking is enabled.
6094 Thu Dec 30 14:28:25 1993 Bill Cox (bill@rtl.cygnus.com)
6096 DELAY CASE works now.
6097 * ch-decl.c (init_decl_processing): Move rest of tasking-related
6098 initialization into tasking_init().
6099 * ch-parse.y (delaycaseaction): Pervasive additions/corrections.
6100 (optsetprio): New non-terminal.
6101 * ch-tasking.c (get_task_name): Delete, obsolete.

6108 correct its functioning.
6109 (build_delay_case_end): Correct the code.
6110 (tasking_init): Lots of tasking-related code moved here from
6111 init_decl_processing.
6112 * ch-tree.h: Update, add prototypes.
6114 Wed Dec 29 10:13:10 1993 Bill Cox (bill@rtl.cygnus.com)
6116 * ch-expr.c (build_chill_indirect_ref): Revert change which
6117 failed full regression testing.
6118 * ch-lex.l (name_type_signal): Add debug output.
6119 * ch-parse.y (structured_variable): Add a debug variable.
6121 Wed Dec 29 02:05:51 1993 Bill Cox (bill@rtl.cygnus.com)
6123 * ch-decl.c (get_next_decl): Revert change which failed full
6126 Tue Dec 28 18:20:14 1993 Bill Cox (bill@rtl.cygnus.com)
6128 DELAY actions work now.
6129 * ch-decl.c: Correct spelling in comments.
6130 (get_next_decl): NULL out the decl's TREE_CHAIN before returning
6131 it, to prevent accidental access to the remembered_decls.
6132 (init_decl_processing): Add wait_event to runtime functions.
6133 * ch-expr.c (build_chill_indirect_ref): Prevent a syntax error from
6134 becoming a seg fault.
6135 * ch-grant.c: Correct a comment.
6136 * ch-loop.c: Delete/correct comments.
6137 * ch-parse.y (delaycaseaction): Add push/poplevel calls. Turn 'sorry'
6138 into rough draft of actual code.
6139 (delayaction): Don't make a new scope here, use get_unique_identifier
6141 (locdec): process event decls here, too.
6142 (mode): Add code to forbid READonly EVENT and BUFFER decls. Delete
6143 code which required EVENTs and BUFFERs to be declared at global scope.
6144 (simple_name_string): Add an EVENTNAME.
6145 * ch-satisfy.c (safe_satisfy_decl): Prevent a syntax error from
6146 becoming a seg fault.
6147 * ch-tasking.c (tasking_setup): Add the event queue's max. length
6148 as the 'entry_point' parameter in the list.
6149 (build_receive_case_start, build_receive_case_label): Defer
6150 calling runtime routine until we know whether we have a signal
6151 or a buffer to wait for.

6153 build_delay_case_label, build_delay_action,
6154 process_event_decls): Added functions.
6155 * ch-typeck.c (chill_similar): Allow all integers of differing
6156 precisions to be similar.

6160 * gcc.c (CHILL SPECS): Delete references to -M -MM -MD -MMD
6161 options. Delete C-specific defines. Disable piping from
6162 pre-processor to cc1chill (even if -pipe is specified), since cc1chill
6163 rewinds its input for its second pass. Piping still works
6164 from cc1chill to as.
6166 Thu Dec 23 12:31:55 1993 Bill Cox (bill@rtl.cygnus.com)
6168 * ch-tasking.c (decl_tasking_code_variable): Assure that the
6169 tasking_code variable is allocated on the permanent obstack.
6170 (tasking_setup): Lots of changes - handle EVENT/BUFFER max.
6171 queue length (passed as the entry_point parameter).
6172 Other changes to variable names to increase 'self-documentation'
6173 the only kind GNU CHILL will get, for a while..
6175 Wed Dec 22 10:46:31 1993 Bill Cox (bill@rtl.cygnus.com)
6177 * ch-decl.c (do_seize): Delete - it's unused. Fix comments.
6178 * ch-loop.c (build_chill_iterator): Convert BY expression
6179 so loop involving a SET works. Additional errors generated
6180 for numbered SET expression as start or end expression.
6181 * ch-tree.h: Prototypes for future DELAY functions.
6182 * ch-typeck.c: Standard indentation.
6184 Tue Dec 21 15:30:57 1993 Per Bothner (bothner@kalessin.cygnus.com)

6194 * ch-lex.l (init_lex): Use new macro to make more terse.
6195 * ch-typeck.c (chill_equivalent): New function.
6196 Also check that ranges have the same bounds.
6197 * ch-typeck.c (my_build_array_ref): Add optional range-checking.
6198 * ch-typeck.c (chill_location): Handle COMPOUND_EXPR properly.
6199 Return 2 if also a referable.
6200 * ch-typeck.c (chill_referable): Re-define to use chill_location.
6201 * ch-tree.h (CH_EQUIVALENT): Re-defined to use chill_equivalent.
6203 * dbxout.c (dbxout_type): Output the type attribute "@S;" to
6204 distinguish a string from a char array, and to distinguish a
6205 bitstring from regulat (power)set. (Needed for Chill.)
6206 * dbxout.c (dbxout_type): Only check for baseclasses in
6207 type.binfo is a vector. (It is used in Chill for tagged unions.)
6209 Fri Dec 17 09:56:07 1993 Bill Cox (bill@rtl.cygnus.com)
6211 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
6212 ch-grant.c, ch-inout.c, ch-loop.c, ch-parse.y,
6213 ch-satisfy.c, ch-tasking.c, ch-tree.h, ch-typeck.c:
6215 * ch-actions.c (chill_expand_assignment): Error if assigning
6216 a value to a BUFFER or EVENT variable.
6217 * ch-expr.c (invalid_left_operand): Delete, unused.
6218 * ch-grant.c (tasking_setup): Call build_enum_tables.
6219 * ch-inout.c (get_final_type_and_range, build_enum_tables,):
6221 (build_chill_writetext): Lots of changes to support other
6222 basic CHILL data types.
6223 * ch-loop.c (build_chill_iterator): Lots of new code to check
6224 the expressions in a STEP loop.
6225 * ch-tasking.c (rc_state): Add fields to flag SIGNAL and BUFFER
6226 names in receivecasealternative. Generate error messages
6227 if they're mixed in the same receive case.
6228 (process_buffer_decl): Renamed from build_buffer_decl.
6229 * ch-tree.h: Fix prototypes.
6230 * ch-typeck.c (smash_dummy_type): Handle all four kinds of LANG_TYPE

6235 * ch-decl.c (push_scope_decls): Re-arrange some more, so
6236 that normal SEIZES (without ALL) are handled before SEIZE ALL.
6238 Wed Dec 15 13:01:22 1993 Bill Cox (bill@rtl.cygnus.com)
6240 * ch-loop.c (declare_temps): Calculate end-of-array pointer
6241 using correct type (NOT chill_integer_type).
6242 (begin_chill_loop): Build loop-bypass expression in the
6243 type of the start expression, not in the unsigned type.
6245 Tue Dec 14 15:41:32 1993 Per Bothner (bothner@kalessin.cygnus.com)
6247 * ch-decl.c (push_scope_decls): Re-arrange so that normal
6248 (non-seize) declarations are proclaim_decl'd *before* we
6249 handle the ALIAS_DECLs for seizes. The advantage is

6252 when a module has both GRANTs and SEIZE ALL.

7006 error message in pass 1.

7015 parameter to know whether to include an init expression.

7059 not error_mark_node.
7060 * ch-actions.c (chill_expand_assignment): Allow such borderline

7223 * ch-grant.c (chill_finish_compile): Add code to spoof
7224 get_file_function_name, so we don't get __tmp_s1_code,
7225 for example, as the module-level code's name.
7226 * ch-loop.c (build_temporary_variable, begin_for_range,
7227 init_loop_counter): Add parameter to decl_temp1 call.

7275 Mon Oct 4 15:43:56 1993 Per Bothner (bothner@kalessin.cygnus.com)
7277 * ch-convert.c (digest_constructor): Convert element to element_type.
7278 * ch-parse.y (end_function): Use DECL_ARGUMENTS to check
7279 for parameterless process.
7281 Fri Oct 1 13:57:30 1993 Per Bothner (bothner@kalessin.cygnus.com)
7283 * ch-typeck.c (chill_location): New function.
7284 Based on lvalue_p, but also handle Chill-specific VARY_ARRAY_REF.
7285 * ch-typeck.c, ch-tree.h (CH_LOCATION_P), ch-convert.c: Use
7286 chill_location instead of lvalue_p.
7289 Fri Oct 1 11:28:42 1993 Bill Cox (bill@cygnus.com)

7305 ch-convert.c (convert): Use it.
7306 * ch-typeck.c (build_chill_slice): Take length rather than upper
7307 bound. This makes it easier to recognize that A(X UP LENGTH)
7308 really has fixed length. Also, if the argument is string,
7309 mark the slice as a string too. Also, handle varying strings.
7311 * ch-typeck.c (conflate_singleton_strings): New global.
7312 * ch-typeck.c (chill_similar): If conflate_singleton_strings is
7313 set (as it currently is), allow CHARS(1)/BOOLS(1) to be similar
7314 to CHAR/BOOL, as required by the 1984 version of Z.200.
7315 * ch-convert.c (convert_to_char): Convert CHARS(1) to CHAR.
7316 * ch-convert.c ( build_array_type_for_scalar): If input is string,
7318 * ch-convert (maybe_turn_scalar_into_arra), ch-tree.h: Removed.
7319 * ch-convert.c (convert): Convert CHAR to CHARS(1).
7321 This fixes 'X // := Y' and is also a general simplification.
7322 * ch-actions.c (chill_expand_assignment): Convert 'LHS OP := RHS'
7323 to 'LHS := LHS OP RHS' (using stabilize_reference on LHS).
7324 Also, call save_expr on RHS if a multiple assignment.
7325 * ch-parse.y (assignaction): Therefore, no longer need to call
7326 stabilize_reference on RHS.
7327 * ch-typeck.c (build_chill_modify_expr), ch-tree.h: Remove
7328 modifycode parameter. Make it the caller's responsibility to
7329 handle <assigning operator>.
7330 * ch-actions.c, ch-decl.c, ch-except.c, ch-expr.c, ch-grant.c,
7331 ch-loop.c: Fix calls to build_chill_modify_expr accordingly.
7333 Wed Sep 29 18:02:55 1993 Per Bothner (bothner@kalessin.cygnus.com)
7335 * ch-lang.c (string_index_type_dummy), ch-tree.h: New variable.
7336 * ch-decl.c (integer_minus_one_node), ch-tree.h: New variable.
7338 * ch-parse.y (arrayindex: modename): Remove useless code.
7339 * ch-satisfy.c (satisfy): Don't gag on string_index_type_dummy,
7340 * ch-tree.c (build_string_type): Pass string_index_type_dummy as
7341 the parent type of the index range.
7342 * ch-typeck.c (layout_chill_range_type): Recognize and handle
7343 string_index_type_dummy - specifically allow an empty range.
7345 Wed Sep 29 13:36:23 1993 1993 Bill Cox (bill@cygnus.com)
7347 * ch-convert.c (convert_to_reference): Check for loc-identity
7348 mismatches correctly (and remove one of those chill_compatible
7350 * ch-decl.c (decl_tasking_code_var): New function, called from
7351 push_extern_process and push_extern_signal.
7352 * ch-parse.y (end_function): Delete parameter. Check current_function_decl
7353 whether it's actually a process, and whether it has parameters.
7354 Make Michael's change simplifying the pass 2 test, preventing a seg
7356 (procedure, process): Change calls to end_function, remove
7357 code saving value from build_process_header. Delete redundant chill_
7358 phrases from some function calls.
7359 * ch-tasking.c: Remove some redundant _chill phrases from function
7361 * ch-tree.h: Remove some redundant _chill phrases from function
7362 names. Add the CH_VARYING_ARRAY_TYPE macro, call it from
7363 all relevant places.
7364 * ch-typeck.c: Use the new macro. Cast TREE_CODEs to chill_tree_code.
7366 Wed Sep 29 13:07:43 1993 Per Bothner (bothner@kalessin.cygnus.com)
7368 * ch-convert.c (convert_to_reference): Remove redundancies.

7370 with a recursive convert call.
7371 * ch-decl.c (do_decl): Add missing compatibility-checking
7372 of initializer (don't depend on convert).
7374 Tue Sep 28 00:02:25 1993 Per Bothner (bothner@kalessin.cygnus.com)
7376 * ch-tree.h (CH_LOCATION_P): New macro.
7377 * ch-typeck.c (layout_chill_range_type): Fix call to
7378 type_for_size, when figuring out a defaulted parent type.
7379 * ch-expr.c (build_chill_lower, build_chill_sizeof): Check
7380 for TREE_CODE_CLASS != 't' rather than == 'd'.
7381 * ch-expr.c (build_chill_function_call): Use CH_LOCATION_P
7382 to check for location, rather than TYPE_CODE_CLASS == 'd'.
7384 * ch-tree.c (build_string_type): Make 2-pass safe. Also,
7385 change parameter to be length, not index type.
7386 * ch-parse.y (mode2), ch-expr.c (build_concat_expr), ch-lex.l
7387 (build_chill_string): Modify callers of build_string_type accordingly.
7388 * ch-lex.l (check_newline): Don't look for # directive inside a
7390 * ch-grant.c (grant_array_type): Make more robust for char-
7391 and bit-strings (allow non-constant sizes). Change parameters
7392 and return types. (raw_decode_mode): Use grant_array_type
7393 for bitstrings. (otherwise): Fix grant_array_type callers.
7395 Mon Sep 27 16:57:57 1993 Per Bothner (bothner@kalessin.cygnus.com)
7397 Remove changes of Sep 15.
7398 * ch-tree.h (CH_SINGLETON_DOMAIN): Removed.
7399 * ch-typeck.c (chill_similar): Don't allow a singleton
7400 powerset to be similar to its domain.
7401 * ch-convert.c (convert_to_boolean): Don't convert a singleton
7402 SET_TYPE constructor to a Boolean.
7404 * ch-actions.c (chill_expand_assignment): Handle IN_EXPR on
7405 LHS of assignment, which is what we're current (temporarily?) using.
7407 Mon Sep 27 06:01:57 1993 Bill Cox (bill@rtl.cygnus.com)
7409 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
7410 ch-grant.c, ch-inout.c, ch-parse.y, ch-satisfy.c,
7411 ch-tasking.c, ch-tree.c, ch-tree.h, ch-typeck.c:
7412 -Wall cleanup. Add prototypes where missing.
7413 Delete unused variables. Cast uses of tree_codes
7414 to chill_tree_code, which they are.
7416 Sun Sep 26 13:09:57 1993 Bill Cox (bill@rtl.cygnus.com)
7418 * ch-decl.c (do_decl): Save initializer in pass zero
7420 * ch-lex.l: Fix comments, indentation.
7421 * ch-parse.y: Standardize error messages to use
7422 uppercase for CHILL keywords rather than quoting them.
7423 Suggestion from docs department.
7424 * ch-tasking.c: Pervasive changes to get processes to
7426 * ch-tree.h: Delete prototypes for functions whic
7427 I made static inside ch-tasking.c.
7429 Sun Sep 26 02:40:02 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7431 * ch-lex.l (yywrap): Call `check_newline' in case the file
7432 started with a line directive.
7434 Sat Sep 25 13:54:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
7436 * ch-decl.c: Expand pre-amble comment.
7437 * ch-decl.c (struct scope, push_module): Use new field
7438 tail_chain_module to build child-module list in order.
7439 (Just to make compiler debugging a little less confusing.)
7441 * ch-decl.c (struct scope): New field weak_decls.
7442 * ch-decl.c (find_implied_types): New interface. Now pre-pend
7443 new enum types to a given input list. This makes it easier to
7444 avoid duplicates, which should at least be more efficient.
7445 Also, handle FUNCTION_DECL.
7446 * ch-decl.c (bind_saved_names): Removed. Distribute its
7447 functionality over new functions (push_scope_decls, pop_scope_decls,
7448 build_implied_names, bind_sub_modules). The goal (which seems to
7449 have been more-or-less attained) was to fix weak name handling.
7450 * ch-decl.c (poplevel): Use new function pop_scope_decls.
7452 * ch-tasking.c (build_signal_struct, build_tasking_message_type):
7453 Use build_decl directly, rather than grok_chill_fixedfields
7454 (which depends on ignore_exprs and has more overhead).
7455 * ch-tasking.c (build_signal_struct): Construct the type
7457 * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
7458 than build_array_ref (which does C-specific "optimizations").
7459 (Hence move my_build_array_ref up earlier in the file.)
7461 Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7463 * ch-tasking.c: Declare static variable `void_ftype_void'.
7464 (chill_tasking_init): Initialize `void_ftype_void' here.
7465 (build_tasking_struct): Use, don't declare `void_ftype_void'.
7466 (generate_tasking_code_variable): Call `do_decl', not
7467 `decl_temp1' to declare TASKING_CODE_NAME.
7468 (tasking_setup): Drop into 1-pass mode so that all
7469 tasking-related declarations are installed in the global
7470 scope. Use correct CHILL types for initializers (since
7471 ptr_type_node doesn't have the right meaning for CHILL).
7472 Also, call `do_decl' instead of `decl_temp1' for
7474 (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
7475 `chill_finish_compile' in sync between passes.
7477 * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
7478 declarations on pass zero. Keep obstacks in sync, and always
7479 call `finish_decl' for pass zero declarations.
7480 (push_chill_extern_function): Keep obstacks in sync, and always
7481 call `finish_decl' for pass zero declarations.
7482 (build_enumerator): Ditto.
7483 (grok_chill_variantdefs): Change PASS test to exclude only
7485 (finish_struct): Ditto.
7486 * ch-expr.c (build_chill_component_ref): Ditto.
7487 (build_chill_binary_op): Ditto.
7488 * ch-tree.c (build_powerset_type): Ditto.
7489 (build_bitstring_type): Ditto.
7490 * ch-typeck.c (build_chill_range_type): Ditto.
7491 (build_chill_struct_type): Ditto.
7493 * ch-decl.c (build_chill_exception_decl): Clarify reasons for
7494 extra pushing and popping of obstacks.
7496 * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
7497 on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
7499 * ch-grant.c (chill_finish_compile): Clear out both
7500 MODULE_INIT_LIST and TASKING_LIST if either contains stuff
7503 * ch-parse.y (rccase_label): Add NAME rules so that pass one
7504 works w/o knowing we're parsing a signal. Simplify SIGNALNAME
7505 rules since we only get SIGNALNAME tokens in pass two.
7506 (sendaction): Ditto.
7507 * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
7508 BUFFERNAME on pass two. The grammar now handles this.
7509 * ch-decl.c (lookup_remembered_decl): Deleted.
7511 Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
7513 * ch-decl.c (lookup_remembered_names): Removed. It was being
7514 misused in ch-lex.l.
7515 * ch-lex.l (name_type_signal): Revert last change. Basically,
7516 we cannot use the C typedef/variable name trick in CHILL, due
7517 due to the language's 2-pass nature.
7518 * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
7520 * ch-tree.h (lookup_remembered_name): Comment out the prototype.
7522 Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7524 * ch-decl.c (do_decl, push_chill_extern_function): Change pass
7525 checks so the pass == 0 case is handled for built-in types.
7526 (push_modedef): Add check for error_mark_node.
7527 (lookup_remembered_decl): New function.
7528 (pushlevel, poplevel) Change pass checks.
7529 (pushdecl): Check type as well for NULL.
7530 (build_enumerator): Handle pass == 0 case.
7531 * ch-lex.l: Use lookup_remembered_decl to get lastiddecl
7533 * ch-parse.y: Set pass to zero to indicate initial decl processing.
7534 Replace NAME references with SIGNALNAME references.
7535 (startaction): Only check copy number if not ignoring actions.
7536 Always call build_chill_start_process.
7537 (optstartset): Don't lookup the instance name.
7538 * ch-tasking.c (generate_tasking_code_variable): Replace
7539 do_decl call with decl_temp1 call.
7540 (build_chill_start_action): Check for ignore_actions here.
7541 (build_tasking_message_type): Layout the type.
7542 (rc_state_type): New structure to keep nested receive-case
7544 (build_chill_receive_case_start, build_chill_receive_case_end):
7548 Fri Sep 24 04:19:15 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7550 * ch-tasking.c (build_chill_receive_case_start): `namedecl'
7551 should be a _DECL, not an IDENTIFIER_NODE.
7553 Thu Sep 23 18:18:24 1993 Per Bothner (bothner@kalessin.cygnus.com)
7555 * ch-decl.c (find_implied_types): Handle VAR_DECLs.
7557 * ch-decl.c (print_lang_identifier): Print IDENTIFIER_OUTER_VALUE.
7558 * ch-actions.c (chill_expand_result): Allow value-less RETURN.
7559 * ch-expr.c (resolve_component_ref): Recognize error_mark.
7561 * ch-convert.c (digest_constructor): Handle a nested powerset tuple.
7562 * ch-satisfy.c (satisfy): Use return value of layout_chill_range_type.
7563 * ch-typeck.c (chill_similar): Repeatedly get parent modes
7564 of ranges, not just once.
7565 * ch-typeck.c (chill_root_resulting_mode), ch-tree.h: New function.
7566 * ch-typeck.c (layout_chill_rang_type): Re-do type-checking
7567 to follow Blue Book better (check for Compatibility).
7569 * ch-tree.h (CH_ROOT_RESULTING_MODE): New macro.
7570 * ch-lex.l (use_seizefile_name, current_seizefile_name), ch-tree.h:
7571 New variables. The latter replaces in_seizefile.
7573 Changes to store in the new DECL_SEIZEFILE field each seize
7574 ALIAS_DECL the name in the most recent use_seize_file directive.
7575 (This requires that use_seize_file directives written to the
7576 grant file be written before the SEIZEs that need it.)
7577 Allow clashing declarations granted into the global scope
7578 (produce a warning), but remember the seizefile case from
7579 (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
7580 The a SEIZE will select the granted decl that matches its
7581 DECL_SEIZEFILE (in other words: grants from the most recent
7582 use_seize_file will be preferred).
7583 * ch-tree.h (DECL_SEIZEFILE), ch-tree.def: New macro.
7584 * ch-tree.h (global_value, IDENTIFIER_GLOBAL_VALUE): Renamed
7585 to outer_value, IDENTIFIER_OUTER_VALUE.
7586 Changes to cause the use_seize_file directives to be written
7587 out in order as they're seen in source.

10270 (start state 'ccitt'): Deleted, unused. Moved unused, but reserved,
10271 tokens to NORMAL state.
10272 (compiler_directive): Replaced by equal_number. Now the only
10273 recursive call to yylex happens in check_newline at the beginning
10276 Sat Apr 10 09:55:50 1993 Bill Cox (bill@rtl.cygnus.com)
10278 * ch-actions.c (build_chill_case_expr): Added from ch-parse.y.
10279 * ch-lex.l (ENTRY, PERVASIVE, ROW, STEP): Add token recognition to
10281 * ch-parse.y (case_expr): Move code into ch-actions.c. There will

10284 * ch-tree.h (build_chill_case_expr): Add prototype.
10285 * ch-typeck.c (build_chill_cast): Allow untyped_expr - just assign the

10288 Sat Apr 10 01:10:51 1993 Per Bothner (bothner@rtl.cygnus.com)
10290 * ch-parse,y (in_pseudo_module): New variable. Try if we're
10291 in a seizefile, but not in a module nested in the seizefile.

10304 * ch-lex.l: Re-write to use start states, to avoid calling
10305 yylex() recursively.
10306 * ch-lex.l (compiler_directive); This is now obsolste. FIXME.
10307 * ch-lex.l: Call push_module and pop_module when reading a
10308 seizefile. This creates a pseudo-module.
10309 * ch-parse.y: Clean up handling of empty declarations and
10310 action statements; semicolons are now optional a number of
10312 * ch-parse.y: Remove some bogus tests for "statement
10313 out of sequence" (they're both legal and work).
10314 * varasm.c (mak_function_rtl): Remove kludge that may
10315 not be necessary (and loses anyway).
10317 Fri Apr 9 09:37:38 1993 Bill Cox (bill@rtl.cygnus.com)

10369 * ch-tree.h (massage_param_node): New prototype.
10370 * ch-decl.c (push_parms): Use new massage_param_node().
10371 * ch-parse.y (pmodearg): Use new massage_param_node().

10417 Fri Apr 2 21:55:14 1993 Per Bothner (bothner@rtl.cygnus.com)
10419 Major re-write of New module/seize/grant stuff.
10420 Now, a grantfile is a spec module and contains all the
10421 top-level declarations of the granting module, not just
10422 those that are granted. It also contains explicit grant
10423 statments naming those declared names that are granted.
10424 It also has seize statements and use_seize_file directives
10425 to correctly handle transitive dependencies.
10427 * ch-parse.y: Change to allow multiple modules per source file.
10428 Allow spec modules (including quasi definitions) as well as
10430 Allow spec modules inside normal modules; these behave as if
10431 they were outermost. This violates the Blue Book, but is
10432 needed by the new grantfile mechanism. (A grant file is a
10433 spec module that gets included by the use_seize_file directive.)
10434 * ch-parse.y (struct module *current_module, push_module,
10435 pop_module): Support module nesting (for spec modules only).
10437 * ch-tree.h (struct module): New.
10438 * ch-grant.c (granted_decls): New list of declarations
10439 that have been granted into the outermode pseudo-module.
10440 * ch-grant.c (decode_mode): If the decl has a name,
10441 always write the name, not just if the decl has already
10442 been written. Since we write out all decls, we can assume
10443 it will be written later, and depend on the forward
10444 declaration kludges to catch it.
10445 * ch-grant.c (decode_decl): Don't write out _EXTERN.
10446 Instead write out standard (Blue Book) quasi-definitions.
10447 * ch-grant.c (push_granted): New function.
10448 * ch-grant.c (seize_implied_names): New function. Re-write
10449 how set element names are seized when a set type is seized.
10450 * ch-grant.c (chill_seize): Work by seraching the
10451 granted_decls list and copying the declaration.
10452 * ch-grant.c (chill_grant): Write all declarations
10453 declared in this module. Write GRANT statements for
10454 those granted. seize statements for decls seized from
10455 other modules. Write extra syntax to make a complete
10457 * ch-grant.c (grant_use_seizefile): Copy use_seize_file
10458 directives into grant file.
10459 * ch-lex.l (setup_seizefile_read): Call grant_use_seizefile.
10461 * ch-lex.l (struct input_state, current_input_state,
10462 push_input_file, pop_input_file): New (type, variable,
10463 function*2). Used to save and restore state on an input file.
10464 * ch-lex.l: Clean up to handle nested input seizefiles
10465 (needed by new grant/seize mechanism.
10466 * ch-lex.l (skip_to_end_of_directive): New function.
10467 * ch-lex.l (compiler_directive: USE_SEIZE_FILE): Make sure
10468 we skip to the end of the directive *before* we switch
10470 * ch-lex.l (setup_seizefile_read): Prevent reading the
10471 same seizefile twice (otherwise likely with new grant/seize).
10472 * ch-lex.l: Recognize SPEC. Misc cleanups.
10474 * ch-parse.y: Fixed foreward references of types.
10475 Removed the unknown_type_node crock.
10476 * ch-decl.c: Remove all uses of unknown_type_node.
10477 Check for TYPE_SIZE zero instead.
10478 * ch-decl.c (fixup_unknown_type): Make sure new mode
10479 gets copied into old mode. Merge their variant chains.
10480 * c-decl.c (lookup_name_current_level): Make non-static.
10481 * ch-decl.c (lookup_name_current_level): No longer needed.
10483 * ch-parse.y (call): Allow an implicitly defined function
10484 name following the CALL keyword.
10485 * ch-tree.h (struct lang_identifier): Add implicit_decl,
10486 and make sure order of fields matches c-tree.h.
10488 * ch-actions.c (lang_init, build_allocate_memory_call,
10489 build_allocate_globals_memory_call): Fix names (add initial '_')
10490 and prototypes of _allocate_[global_]memory (2nd param is ref).
10491 Use build_chill_function_call, not build_function_call,
10492 so the reference parameter gets handled.
10493 * ch-actions.c. (lang_init): Make sure boolean_{true,false}_node
10494 have boolean_type_node as their types.
10495 * ch-actions.c (build_chill_lower, build_chill_upper): Fix to
10496 work for arrays with BOOLEAN_TYPE ranges (and simplify some).
10498 * ch-except.c: Make sure an end_label is generated,
10499 and jump to it if there is no exception.
10501 * ch-convert.c (convert_to_reference): Strip off NOP_EXPR casts.
10502 * expr.c (expand_expr): Handle NOP_EXPR as Chill-style casts.
10503 (Need cleaning up and FSF installation!)
10504 * ch-parse.y: If taking the address of a cast, move the
10505 ADDR_EXPR inside the NOP_EXPR.
10507 * ch-typeck.c (my_build_array_ref): Simplified, more suitable
10508 versions of build_array_ref from c-decl.c. (E.g. don't barf
10509 if index type is char or bool.)
10510 * ch-typeck.c (build_chill_array_ref): Use my_build_array-ref.
10512 * ch-typech.c (build_chill_bin_type): New function.
10513 Support BIN(N) range type specification.
10514 * ch-parse.y (mode2), ch-lex.l: Recognize BIN(N).
10516 * ch-tree.h (CH_SIMILAR): Redefine in terms of chill_similar.
10517 * ch-typeck.c (chill_similar): New function. Recognize that
10518 that range types are similar to their parent types.
10520 * ch-tree.h: Declare flag_local_loop_counter.
10521 * ch-loop.c: Whether the loop variable is local to the loop
10522 in now controlled by flag_local_loop_counter, instead of
10523 #ifdef'd on CREATE_SCOPE.
10524 * ch-actions.c (lang_decode_option): Recognize flags
10525 "-f[no-]local-loop-counter".
10526 * toplev.c (lang_options): Add Chill flags -f[no-]local-loop-counter.
10528 * varasm.c (make_function_rtl): Due to problems with forward
10529 references, don't rename nested functions in Chill. (Kudge!)
10531 Sun Mar 28 10:12:45 1993 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10533 * ch-lex.l (push_back, readstring): Fix prototypes.
10535 Fri Mar 26 18:32:15 1993 Bill Cox (bill@rtl.cygnus.com)
10537 * ch-parse.y: Put %type directives back into alpha order.

10544 * ch-parse.y (get_type_of): Add function to deal with possible fwd
10545 declared type name. Call it from lotsa places. Add lotsa checks
10546 for error_mark_node. Standardize indentations.
10548 Thu Mar 25 15:00:11 1993 Bill Cox (bill@rtl.cygnus.com)

10552 * ch-parse.y (action): Add recognition for allocate_memory and
10553 allocate_global_memory system calls.
10554 (mode2): Remove ill-conceived error check that broke REFs to
10555 as-yet-undeclared types. Check for IDENTIFIER_NODE, lookup its
10556 DECL if there, pass TREE_TYPE of decl to build_pointer_type.
10557 (variantfields, varianthack): Clean up.
10558 (variantfield): Check for IDENTIFIER_NODE, lookup its DECL if
10559 there, pass TREE_TYPE of decl to grok_fixedfields.
10560 (labellist): Explicitly assign error_mark_node to signal error.
10561 * ch-typeck.c (chill_compatible): Report FALSE for bad parameters,

10594 array and its type get on the permanent obstack.
10595 * ch-grant.c (write_grant_file): Don't write the _INIT=name
10596 specifier: It isn't needed, and loses (because of funny
10597 characters in the chill_initializer_name).
10598 * ch-decl.c (push_synmode): Set TYPE_NAME(mode) = syndecl.
10599 * ch-lang.c (finish_chill_enum): Don't allocate a dummy
10600 TYPE_DECL for the enum. I don't think it is needed (?),

10605 * ch-grant.ch (raw_decode_mode): New function, based on old
10607 * ch-grant.c (decode_mode); This is now just a wrapper around

10617 after each statement. Move convert call into
10618 chill_expand_assignment from ch-parse.y.
10619 * ch-grant.c: Generally re-order, clean up. Include Per's decode_mode

10641 was intended to be equality test. Remove unused variables.
10642 * ch-tree.h: Add prototype. Remove unused EXCP_CODE enumeration, and
10643 prototyping editorial comments.
10644 * ch-typeck.c: Disable generation of code to validate array index for
10645 now. Should be done as a call-back from more generic array_ref code.
10646 Clean up parameter checking. Remove unused variables.

10768 * expr.c (expand_expr): Use actual library name for __inpowerset
10770 * stor-layout.c (variable_size): Disable complaint about variable-
10771 size type or decl at file scope. Perhaps later this s.b. a warning.

10779 actual library names. Change references to boolean_type_node
10780 to references to the TREE_CODE == BOOLEAN_TYPE, to follow the
10782 build_set_expr: Remove length parameter, call powersetlen() instead.
10783 remove handling of CHAR arrays - they're handled in build_char_array_expr.

10785 need bitcount instead.
10786 build_chill_compound_expr, internal_build_compound_expr: Copy from C
10787 version that does stuff we don't want.
10788 build_binary_op: Check for in_size_in_bytes return < 0, indicating

10794 build_chill_length: Move VARYING array handling before regular char
10796 * ch-expr.c chill_expand_expr: Disable concatenate code - we need to
10797 the VARYING status of the target to do this correctly. Use powersetlen
10798 for the powerset operations, not a byte length.
10799 * ch-loop.c: Make CREATE_SCOPE #define to enable creation of a new scope
10800 for each CHILL loop, as Z.200 requires. Add powerset and error flags
10801 to loop structure. Evaluate user's powerset expression into a temp,
10802 scan it destructively with __ffsetclrpowerset or __flsetclrpowerset
10803 for powerset loop. Only do loop-end assignments if NOT a powerset
10804 loop, which has much less overhead now.

10850 comes out error_mark_node, set ERRONEOUS.
10852 * ch-actions.c (build_chill_binary_op_1): If EXP is NULL_TREE,
10855 * ch-action.c (chill_comptypes): Test for structural
10856 equivalence of enums.

11022 * ch-lex.l (convert_bitstring), Changed SET_TYPE_CONSTRUCTOR to
11023 take a list of elements which are in the set. This corresponds

11026 New functions, to expand SET_TYPE CONSTRUCTORs.
11027 * varasm.c (output_constructor): Use pack_set_constructor

11033 things in the correct order.
11034 * c-typeck.c (chill_initializer_constant_valid_p): Kludge
11035 needed to export a static function.
11036 * ch-typeck.c (convert): Avoid needlessly (and lossingly) calling
11037 chill_expand_tuple to convert fix string to varying.
11038 * ch-actions.c (build_chill_binary_op): Promote short
11039 integer operands if needed (otherwise emit routines barf).

11042 * ch-parse.y (location): If IDENTIFIER is a CONST_DECL

11068 * ch-parse.y: Add working exception handling support.
11069 * ch-lex.l, ch-parse.y: Prefer standard type terminology
11070 (BOOLS, CHARS) even though non-standard (BITS, CHAR) is ok.
11071 * ch-grant.c: Fix various problems related to granting
11072 types such as bitsets.
11073 * ch-tree.c (build_bitstring_type): Set TYPE_MIN_VALUE
11074 to distinguish bitstrings from powersets (in the same way
11075 we distinguish char strings from char arrays).
11076 * ch-tree.h: New macro CH_BOOL_TYPE_P.
11077 * ch-tree.h, ch-actions.c (lang_init), ch-grant.c (decode_mode):
11078 Undo kludge where integer_type_node was hardwired to 16 bits.
11079 Make integer_type_node etc have the same size as in cc1.
11080 New types chill_integer_type_node and chill_unsigned_type_node
11081 that correspond to the Chill source types INT and UINT.
11082 For now, these match the C 'short' types, but that should
11083 become a configuration option later,

11087 * ch-actions.c (build_chill_unary_op): allow NOT of a set.

11094 * ch-loop.c (begin_chill_loop, end_chill_loop): remove
11095 emit_nop() calls - they now (since exceptions) cause seg faults.

11098 * ch-tree.h: remove prototypes added to c-tree.h.
11099 * ch-typeck.c (build_chill_array_ref): correct getting domain

11105 * ch-tree.def: add a new tree type - just for varying array
11106 references. We were using ARRAY_REF, but the underlying C
11107 code also generates that one.
11108 * ch-convert.c, ch-expr.c, ch-typeck.c: use the new tree type.
11110 Sun Feb 7 17:33:17 1993 Bill Cox (bill@rtl.cygnus.com)

11125 * ch-actions.c (build_chill_exception_decl): Change decl

11128 * ch-actions.c: Adjust interface to cause_exception accordingly.
11129 * ch-typeck.c (build_chill_array_ref): Cause rangefail if
11130 index > limit, not >= limit.

11136 FUNCTION_TYPE, not FUNCTION_DECL.
11137 nreverse arg list to build_chill_array_ref.

11581 newlines and check for # directives.
11582 * ch-lex.l (syntax): Don't recognize #-directives; these
11583 are now handled by check_newline.
11584 * ch-actions.c (lang_init): Call the modified version of
11585 check_newline(). Do this at the *after* we've initialized
11586 standard types, so this can be done while lineno is still 0.
11588 Sat Jan 2 10:57:20 1993 Bill Cox (bill@cygnus.com)
11590 * ch-hash.h, chill.gperf: add remaining reserved words.
11592 Sat Jan 2 09:59:55 1993 Bill Cox (bill@cygnus.com)
11594 * ch-tree.h, ch-parse.y, ch-lex.l: add remaining reserved words,
11595 names for exceptions
11597 Fri Jan 1 12:30:31 1993 Fred Fish (fnf@cygnus.com)
11599 * ch-tree.h (JOINER): Define joiner character the same way
11601 * ch-grant.c (chill_start_module_code): Use JOINER character
11602 to implement name mangling for the initializer function name.
11603 Algorithm is designed to be simple, distinct from C++ mangled
11604 symbols, and easy to convert to demangled form.
11606 Thu Dec 31 10:30:51 1992 Bill Cox (bill@rtl.cygnus.com)
11608 * ch-expr.c: make array assignments work with indirect refs.
11609 * ch-actions.c: prepare for array parameter handling.
11610 * ch-loop.c, ch-parse.y, ch-tree.def, ch-typeck.c: clean up.
11612 Thu Dec 31 15:29:20 1992 Per Bothner (bothner@rtl.cygnus.com)
11614 * ch-lex.l (yy_input): Re-write to return more than one
11615 character at a time (execpt when reading seize-files).
11616 Don't increment lineno until we start reading the next line.
11617 This fixes some off-by-one errors in lineno.
11619 Wed Dec 30 16:15:23 1992 Per Bothner (bothner@rtl.cygnus.com)
11621 * ch-convert.c: Assume use of new common.c.
11622 * ch-convert.c (convert_to_reference, convert_from_reference):
11623 New routines, to handle loc-identity declared variables and
11624 LOC parameters (both of which are implemented as references).
11625 * ch-lang.c (convert_to_boolean, convert_to_char): Move to
11626 ch-convert.c, where they would seem to belong.
11627 * ch-convert.c (convert): New function, since we no longer
11628 link in c-convert.c.
11629 * ch-expr.c (chill_expand_assignment): Handle by calling
11630 convert() instead of chill_comptypes().
11631 Also handle the LHS being a reference.
11632 * ch-parse.y: Add a procedure call as an action.
11633 * ch-parse.y (locdec, optlocinit): Move handling of
11634 loc-identity declarations from optlocinit to locdec
11635 - and add working semantics for it.
11636 * ch-parse.y (seizestatement, visibilty_stmt): Simplify.
11637 * ch-parse.y (grantstatement etc): Don't bother making list.
11638 * ch-lex.l: #include <sys/types.h> before <sys/stat.h>.
11640 Wed Dec 30 16:06:55 1992 Bill Cox (bill@rtl.cygnus.com)
11642 * ch-parse.y, ch-expr.c: add support for declaring & assigning
11644 * ch-typeck.c: allow VARYING structures in assign_type_to_expr.
11646 Tue Dec 29 15:28:48 1992 Bill Cox (bill@cygnus.com)
11648 * ch-actions.c: implement expressions of arrays of char,
11649 ( concatenation, relationals ), correct type of code parameters
11650 * ch-expr.c: correct type of code parameters
11652 Tue Dec 29 11:16:19 1992 Bill Cox (bill@cygnus.com)
11654 * ch-decl.c: cleanup.
11655 * ch-parse.y: put emit_line_note() calls in lotsa places,
11656 per Fred's request; be sure that statements get counted also.
11657 * ch-lex.l: standardize function headers.
11659 Tue Dec 29 10:41:56 1992 Fred Fish (fnf@cygnus.com)
11661 * ch-decl.c (start_chill_function): Always return 1, rather
11662 than a random value.
11663 * ch-lex.l (check_newline): Add a version for chill that
11664 just snarfs the right value for main_input_filename out of
11665 the first line of the input file, without disturbing the
11666 lexer state or requiring it's assistance.
11667 * ch-actions.c (lang_init): Call check_newline, like the
11668 other language frontends, to get main_input_filename set
11669 from first line of input file.
11671 Mon Dec 28 18:49:01 1992 Bill Cox (bill@cygnus.com)
11673 * ch-parse.y: clean up conflicts. The remaining one is
11676 Mon Dec 28 17:28:40 1992 Bill Cox (bill@cygnus.com)
11678 * ch-parse.y, ch-lex.l, ch-actions.c: add stubs for I/O,
11679 clean up some parser conflicts.
11681 Mon Dec 28 15:00:20 1992 Bill Cox (bill@cygnus.com)
11683 * ch-parse.y, ch-lex.l: add keywords and parsing for most of
11686 Sat Dec 26 20:48:23 1992 Fred Fish (fnf@cygnus.com)
11688 * chillrt/chillrt0.c: Oops, SVR4 doesn't need leading '_'
11689 on build_exceptions.
11691 Sat Dec 26 11:00:36 1992 Fred Fish (fnf@cygnus.com)
11693 * ch-grant.c (chill_finish_module_code): Call
11694 assemble_constructor_alias rather than assemble_constructor.
11695 * varasm.c (assemble_constructor_alias): New function,
11696 like assemble_constructor, but also handles the case where
11697 ASM_OUTPUT_CONSTRUCTOR is not defined and GNU ld is not
11698 being used. Emits a symbol table alias name with the correct
11699 prefix for collect to find and add to the __CTOR_LIST__.
11700 * chillrt/chillrt0.c: Build on previous hack that gets
11701 _build_exceptions into the __CTOR_LIST__, to make it work
11702 for both the non GNU-ld case and for the SVR4 case.
11704 Tue Dec 22 18:24:55 1992 Bill Cox (bill@cygnus.com)
11706 * ch-loop.c: clean up location enumeration - one more

11713 Tue Dec 22 14:42:14 1992 Bill Cox (bill@cygnus.com)
11715 * ch-lex.l: readability cleanup
11717 Mon Dec 21 14:58:39 1992 Bill Cox (bill@cygnus.com)
11719 * ch-parse.y, c-decl.c: Add Jukka's Pascal WITH code.
11720 ch-loop.c: rough draft of location enumeration
11721 ch-lex.l, ch-expr.c, ch-decl.c: minor cleanup
11722 ch-actions.c: finish making pred() and succ() work.
11724 Mon Dec 21 10:04:35 1992 Bill Cox (bill@cygnus.com)
11726 * ch-actions.c: allow pred(char) and succ(char).
11728 Sun Dec 20 16:04:28 1992 Bill Cox (bill@cygnus.com)
11730 * ch-expr.c, ch-actions.c, ch-parse.y, ch-loop.c,
11731 c-expr.c: make DO WITH work.
11733 Sun Dec 20 12:22:53 1992 Bill Cox (bill@cygnus.com)
11735 * ch-loop.c, ch-actions.c, ch-typeck.c: powerset loops
11738 Sat Dec 19 14:20:23 1992 Per Bothner (bothner@cygnus.com)
11740 * c-typeck.c (process_init_constructor): Add warning if
11741 there is a duplicate default initializer element.
11742 * ch-typeck.c (chill_give_type_to_expr): New function,
11743 to handle coercion of an expression to context-given type,
11744 Takes care of untyped tuples, and case expressions.
11745 * ch-decl.c (do_decls), ch-typeck.c (chill_expand_return,
11746 chill_expand_result), ch-parse.y <assignaction>:
11747 Use chill_give_type_to_expr().
11748 * ch-typeck.c (chill_handle_case_label): New parameter list,
11749 to handle the (new) conventions for <case_label>, including
11750 default elements and ranges.
11751 * ch-parse.y <expanded_case_label>, ch-typeck.c
11752 (expand_case_expr): Use new version of chill_handle_case_label.
11753 * ch-decl.c (push_syndecls): Change parameters: Instead of
11754 TREE_LIST representing a compete <synonym definition statement>,
11755 just pass the parts of a single <synonym definition> as 3
11756 different parameters. Also, use chill_give_type_to_expr(),
11757 to handle untyped tuples in the RHS.
11758 * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct
11759 a tree - just call push_syndecls() on each <synonum_definition>
11761 * ch-parse.y (exprlist_get_single): Remove; no longer needed.
11762 * ch-parse.y: Handle <tuple> without mode name diferently from
11763 <tuple> with mode name. The latter is a <primval> that can be
11764 in most contexts, but if the <mode name> is missing, the <tuple>
11765 is only allowed in certain contexts. Use the new non-terminal
11766 <untyped_expr> to indicate those contexts where untyped tuples
11767 (and case expressions) are valid because the expression gets a
11768 type from its context (such as the RHS of an assignment).
11769 Use chill_give_type_to_expr in those contexts.
11771 Sat Dec 19 14:01:26 1992 Bill Cox (bill@cygnus.com)
11773 * ch-actions.c, ch-loop.c, Makefile.in: looping stuff.
11775 Sat Dec 19 10:16:20 1992 Bill Cox (bill@cygnus.com)
11777 * ch-parse.y: clean up warning messages from byacc. bison
11778 still complains thrice.

11782 * ch-actions.c (maybe_chill_comptypes): Delete unused
11784 (chill_comptypes): Add new parameter ERRSTR. All callers
11786 (build_chill_binary_op): Fix indentation to match GNU coding
11789 Fri Dec 18 08:18:13 1992 Bill Cox (bill@rtl.cygnus.com)
11791 * ch-parse.y, ch-expr.c, ch-actions.c, expr.c: major

11801 a default initializer element.
11802 * ch-parse.y: Implement default elements for tuples
11803 (as in '(else):' and '(*):' ).
11805 * ch-parse.y: Previous change to dis-ambiguate case-labels
11806 seems to have allowed getting rid of all of the expr_or_list hair.
11807 * ch-decl.c (do_decls): Undo Tiemann's change to "Handle
11808 initialization of multiple variables by a tuple" - the
11811 Wed Dec 16 11:17:53 1992 Bill Cox (bill@cygnus.com)
11813 * ch-parse.y: complete re-write of DO statement handling.
11814 now operational, except WITH is stubbed out. Improved
11815 syntax error message.
11816 * ch-actions.c: DO support: high_domain_value(), low_domain_value ().
11817 * ch-expr.c: fixes to IN_EXPR handling.
11819 Tue Dec 15 17:15:13 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11821 * ch-grant.c: Add casts to alloca return to avoid compiler warning.
11822 * ch-lex.c: Likewise.
11824 * Makefile.in (ch-lex.c): Delete incorrect free declaration added
11825 by flex to avoid compiler error.
11827 Tue Dec 15 08:41:08 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11829 * ch-decl.c (do_decls): Handle initialization of multiple
11830 variables by a tuple.
11832 * ch-decl.c (do_decls,start_chill_function): Make DECL public
11833 if we're doing a GRANT ALL at top level.
11835 * ch-lang.c (build_range_type): Deal with typecast to CHAR in
11838 * c-typeck.c (digest_init): SET_TYPE is not a scalar type.
11839 BOOLEAN_TYPE and CHAR_TYPE are scalar types.
11841 Mon Dec 14 14:58:32 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11843 * ch-lex.l (get_chill_{linenumber,filename}): New functions.
11844 (convert_number): Use LONG_TYPE_NODE instead of INTEGER_TYPE_NODE.
11846 Mon Dec 14 13:36:44 1992 Bill Cox (bill@cygnus.com)
11848 * expr.c: install and test newer Pascal IN_EXPR code,
11849 but don't activate it - it's very verbose.
11851 Mon Dec 14 00:22:49 1992 Fred Fish (fnf@cygnus.com)
11853 * Makefile.in (LANGUAGES): Add chill.
11854 * Makefile.in (CHILL_INSTALL_NAME, CHILL_CROSS_NAME):
11855 New macros for chill native and cross installation names.
11856 * Makefile.in (COMPILERS): Add cc1chill.

11869 Sun Dec 13 14:07:32 1992 Bill Cox (bill@cygnus.com)
11871 * ch-actions.c: fix unary operations, modulus ops,
11872 (discovered after extending regression tests).
11874 Sun Dec 13 12:16:32 1992 Bill Cox (bill@cygnus.com)
11876 * resync with Michael and Wilfried
11878 Sun Dec 13 09:11:25 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11880 * ch-parse.y (output_constant): Fixed some whitespace
11882 * ch-tree.h: Add declarations for new chill functions that
11883 have been implemented but not (yet) declared.
11885 Sat Dec 12 00:17:23 1992 Per Bothner (bothner@cygnus.com)
11887 * c-typeck.c (process_init_constructor): Warn about duplicate
11888 labels for labelled initializer elements.
11889 * ch-lex.l (various operator tokens, such as "+"): Don't
11890 set yylval.code to a TREE_CODE; this is better done in parser.
11891 * ch-parse.y: Some work with case labels and tuples.
11892 Get literal range as tuple (and case) labels working.
11893 Fix some problems introduced by recent grammar overhaul.

11897 * ch-actions.c, ch-parse.y ch-tree.h ch-expr.c, ch-typeck.c:
11898 got long, real expressions working. We can also call a func-
11899 tion and use its return value.
11901 Thu Dec 10 14:45:17 1992 Per Bothner (bothner@cygnus.com)
11903 * ch-parse.y: Major change to remove or at least identify
11904 parser ambiguities. One result: We now allow actions that
11905 start with '(', as required by teh Blue Book. This does break
11906 some things; look for FIXME for things that need work.
11907 * ch-typeck.c (chill_expand_case_expr): We need an extra
11908 level of looping to (in the future) support <case label
11909 specification>s with more than one <case label list>.

11933 on arrays of BOOLs.
11935 Mon Dec 7 08:55:20 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11937 * ch-actions.c (lang_init): Set LINENO to 1 at beginning to
11938 indicate we are done with initialization.
11940 * ch-decl.c (do_decls): Set TREE_PUBLIC if we are doing a
11942 (start_chill_function): Ditto.
11944 * ch-lex.c (convert_bitstring): Set TREE_CONSTANT.
11945 (compiler_directive): Don't confuse compiler directives with
11946 equality comparison operators.
11948 * ch-parse.y: Clear CURRENT_LOCNAMELIST after calling do_decls.

11961 * tree.def: Move CARD_EXPR and SET_LE_EXPR back down with the other
11962 Pascal-required ones, since C++ no longer needs them. When
11963 Chill's public, a comment can be added to the effect that
11964 SET_LE_EXPR is also used by Chill.
11966 Fri Dec 4 12:05:01 1992 Bill Cox (bill@cygnus.com)
11968 * Restore CARD_EXPR and SET_LE_EXPR to tree.def.

11995 * chill (library): Remove chillrt0.o.
11996 * chillrt/Makefile: Remove maintenance of chillrt0.o as a

12007 (push_newmode,push_synmode): Call `fixup_unknown_type' when we
12008 see a declaration that uses `unknown_type_node'. FIXME.
12010 * ch-grant.c (decode_constant): New function.
12011 (decode_decl): Call `decode_constant' for CONST_DECLs.
12013 * ch-lex.l (char action): Use ridpointers instead of
12014 lookup_name to get "char"'s declaration.
12016 * ch-parse.y: Call `build_lang_decl' instead of `build_decl'
12017 when we need to build a TYPE_DECL.
12019 Tue Dec 2 09:44:05 1992 Bill Cox (bill@cygnus.com)
12021 * ch-typeck.c: clean up a gcc warning with a forward
12022 declaration of build_string_type.
12024 Tue Dec 1 16:51:05 1992 Bill Cox (bill@cygnus.com)
12026 * ch-actions.c: completely remove those builtin calls
12027 that are duplicated in c-decl.c
12029 Tue Dec 1 16:38:51 1992 Fred Fish (fnf@cygnus.com)
12031 * ch-actions.c (lang_init): Ifdef out initializations for
12032 __builtin_abs and __builtin_fabs, since they are duplicates of
12033 initializations in c-decl.c, and trigger spurious warnings.
12035 Tue Dec 1 16:35:18 1992 Bill Cox (bill@cygnus.com)
12037 * ch-parse.y: make size() work with a typename argument.

12046 * ch-lex.l: fix char-type
12048 Tue Dec 1 11:10:56 1992 Bill Cox (bill@cygnus.com)
12050 * ch-parse.y, ch-actions: added parsing and processing
12051 for upper, lower, and length built-ins.
12053 Tue Dec 1 09:40:49 1992 Fred Fish (fnf@cygnus.com)
12055 * dwarf.h (LANG_CHILL): Add as GNU extension.
12056 * dwarfout.c (output_compile_unit_die): Test language_string and
12057 set LANG_CHILL if appropriate.
12058 * ch-parse.y (language_string): New for chill.
12059 * chillrt: Renamed directory chill to chillrt.
12060 * chill: Renamed chillsh to chill.
12061 * Makefile.in: Adjust for renamings.
12062 * chillrt/Makefile: Adjust for directory renaming.
12064 Mon Nov 30 17:35:33 1992 Fred Fish (fnf@cygnus.com)
12066 * chillsh: New script frontend (ala g++), installed as "chill".
12067 Can't be called "chill.sh" because make tries to cat it into the
12068 "chill" directory. Can't be called just "chill" cause that's
12069 already there as a directory.
12070 * Makefile.in: Add rules to install chillsh as "chill".
12071 * chill/libchill.c: Temporarily ifdef out stuff that wants
12072 to conflict with i486/SVR4 runtime or wants to pull in librmt.a,
12073 which itself causes linkage to fail.
12075 Mon Nov 30 16:28:19 1992 Bill Cox (bill@cygnus.com)
12077 * ch-lex.l: added keywords for TRUNC, ROUND, FLOAT, LFLOAT
12078 conversion routines.
12079 * ch-parse.y: added %tokens for TRUNC, ROUND, FLOAT, LFLOAT.
12080 Added production for SIZE(expr).
12081 * ch-actions.c: Add semantic routine chill_sizeof ().
12083 Mon Nov 30 16:20:40 1992 Per Bothner (bothner@cygnus.com)
12085 * ch-lex.l, ch-parse.y: Translate token PFEIL into English ARROW.
12086 * ch-parse.y (op6): Remove handling of string repetition operator,
12087 until we can figure out a way to parse it correctly.
12088 * ch-parse.y (optmodename): New non-terminal.
12089 * ch-parse.y (tuple): Merge the two variants using optmodename.
12090 * ch-parse.y (location): Add semantic actions for
12091 dereferencing operator ->.
12093 Mon Nov 30 08:01:29 1992 Bill Cox (bill@cygnus.com)
12095 * ch-actions.c: removed compile warning, better code for abs.
12097 * ch-parse.y: add productions for builtin functions succ, pred,
12098 abs, and size. Add %tokens also. Sort %tokens alphabetically.
12100 * ch-lex.l: add parsing for builtin function names, such as abs,
12101 pred, succ, etc. Put flex -a option into Makefile.in, so we can
12102 clean up the lexer soon.
12104 Tue Nov 24 14:18:48 1992 Per Bothner (bothner@rtl.cygnus.com)
12106 * ch-typeck.c (chill_handle_case_label, chill_handle_case_default):
12107 New functions, for code common to CASE actions and expressions.
12108 * chill.y: Replace some code by calls to chill_handle_case_label
12109 and chill_handle_case_default.
12110 * ch-typeck.c (chill_expand_case_expr): Add semantics.
12112 * tree.c: Change doing_chill_thang from extern to common.
12114 Mon Nov 23 18:34:22 1992 Per Bothner (bothner@rtl.cygnus.com)
12116 * ch-tree.def: New CASE_EXPR type, for case expressions.
12117 * ch-expr.c (chill_expand_expr): Hook for CASE_EXPR.
12118 * ch-typeck.c (chill_expand_case_expr): New function.
12119 Placeholder to implement case expressions.
12120 * ch-typeck.c (chill_expand_result, chill_expand_return):
12121 Handle mode-unspecified tuples and case expressions in
12122 the context of RETURN and RESULT actions.
12123 * chill.y (assignaction): Handle case expressions in the
12124 context of the RHS of an assignment action.
12125 * chill.y (caseaction): Remove spurious duplicate OF in grammar.
12126 * chill.y: Handle labeled structure tuples.
12127 * chill.y: New rules to parse CASE expressions.
12128 * tree.c (build_function_types): Allow Chill functions
12129 to return arrays and functions.
12131 Wed Nov 18 13:50:28 1992 Per Bothner (bothner@rtl.cygnus.com)
12133 * ch-typeck.c (chill_expand_tuple): New function. Expand a
12134 tuple (constructor) given an expected (context) type.
12135 * chill.y: Implement 'LHS := TUPLE' using expand_chill_tuple,
12136 using the mode of the LHS and the expected type of the TUPLE.
12137 * chill.y: Implement initialization.
12138 * chill.y: Fix some syntax bugs (forbidlist must be surrounded
12139 by parentheses), and remove or note ambiguities.
12140 * chill.y: Started converting layout style to be like c-parse.in.
12141 * chill.y: Implement IF expressions.
12142 * chill.y: Added syntax rules for tuples. Labelled and unlabelled
12143 array tuples should now work (in some contexts).
12144 * ch-actions.c: Initialize doing_chill_thang to 1.
12145 * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
12146 initializer, to make pushdecl and finish_decl work.
12147 * c-decl.c (convert_for_assignment): If Chill, don't convert
12148 function and arrays into pointers. (Maybe functions should
12149 still be converted?)
12150 * c-typeck.c (grokdeclarator): Allow functions in Chill
12151 to return arrays and functions.
12153 Mon Nov 16 15:40:47 1992 Per Bothner (bothner@rtl.cygnus.com)
12155 * chill.y (exprlist_get_single): New function, used when
12157 * chill.y: Re-did parsing of tuples to remove ambiguities.
12160 Tue Nov 10 16:30:55 1992 Per Bothner (bothner@rtl.cygnus.com)
12162 * ch-typeck.c (chill_expand_result); Set TREE_SIDE_EFEFCTS
12163 flags on assignment to result.
12164 * ch-typeck.c (build_chill_array_ref): Subtract lower
12165 bound of domain if non-zero. Preliminary hook for range checking.
12166 * ch-tree.h, chill.l: Combine variables range_check and
12167 range_check_disabled into global variable range_checking.
12168 * ch-tree.h: Better definitions of CH_CLASS_IS_VALUE
12169 CH_CLASS_IS_DERIVED.
