3488 Wed Sep 21 00:54:21 1994 Per Bothner (bothner@kalessin.cygnus.com)
3490 Give up on trying to use the cleanup mechanism in stmt.c to
3491 make sure the exception handler get unlinked on goto/exit/return.
3492 Instead, do it ourselves. (Much simpler.)
3493 * except.c, ch-tree.h (action_nesting_level): New global.
3494 * ch-tree.h (DECL_ACTION_NESTING_LEVEL): New macro.
3495 * decl.c (define_label): Set DECL_ACTION_NESTING_LEVEL.

3534 * except.c (emit_setup_handler): Add a cleanup to
3535 unlink from exception stack if we return/exit/goto from here.
3536 * loop.c (begin_loop_scope): Move pushlevel from here ...
3537 * parse.c (parse_do_action): ... to here.

3555 * lex.l (readstring): Add processing of control sequence
3556 in character string literals. The granting mechanism writes
3557 this to grant files.

3561 * expr.c (compare_records): In case of -fpack do always
3562 a memcmp instead of comparing each field of the

3576 the entrypoint of a process.
3577 (build_process_header): Change PROCESS arguments to be
3578 like arguments of a function. There will be a wrapper
3579 which is the real entry point for a PROCESS. This wrapper
3580 is automatically build after a PROCESS definition and gets
3581 as argument a pointer to a structure looking like the
3582 arguments of the PROCESS. This wrapper will call the
3583 PROCESS (see build_process_wrapper).
3584 (build_process_wrapper): New function (see above).
3585 (build_start_process): Change processing of arguments.
3586 (tasking_setup): Add processing of a different entry point

3613 will get generated every time a new Makefile will get
3615 * Makefile.in (GNUCHILL_VERSION): Remove it, its defined in
3618 * chill.in: In case of -fgrant-only pass "-S -o /dev/null"
3619 to the compiler to avoid generation of an object file.
3621 Thu Sep 8 12:07:28 1994 Per Bothner (bothner@kalessin.cygnus.com)
3623 * convert.c (display_int_cst), ch-tree.h: New function.
3624 * convert.c (digest_array_tuple): Use digest_int_cst to
3625 provide better error messages. Return error_mark_node on error.
3626 * grant.c (decode_const): Simplify by using digest_int_cst.
3627 * grant.c (format_character, find_assoc): Removed.
3629 * decl.c (do_decl): Add missing TREE_CHAIN.
3631 * decl.c (finish_incomplete_decl): Removed.
3632 (init_decl_processing): Don't set incomplete_decl_finalize_hook.
3633 (finish_decl): Remove old C-specific code to deduce size of
3634 array from initialization.
3635 (complete_array_type): Just make it abort.
3637 * except.c (finish_handler_array): Avoid calling C-specific kludge
3638 complete_array_type.
3640 * convert.c (digest_constructor): Rename, and re-write to:
3641 (digest_array_tuple, convert): No longer use the code in
3642 ../c-typeck.c; use a Chill-only implementation (sigh).
3644 * typeck.c (chill_expand_tuple): Remove unneeded call to
3645 complete_array_type.
3647 * expr.c (fold_set_expr), grant.c (decode_constant),
3648 typeck.c (expand_constant_to_buffer): Update name of called
3649 function unpack_set_constructor to get_set_constructor_bits.
3650 * expr.c (powersetlen ): Remove redundant call to convert.
3652 * ch-tree.h (unpack_set_constructor): Removed obsolete declaration.
3654 * inout.c (build_chill_writetext): Handle 64-bit integer literals
3655 by trying to convert them to a smaller type.
3657 * lex.l (convert_number): Always use long long type (possibly
3658 unsigned) to avoid problems with constant folding truncation.
3660 Mon Sep 5 08:08:22 1994 Wilfried Moser (moser@rtl.cygnus.com)
3662 * ch-tree.h (enum chill_built_in_function): Add BUILT_IN_QUEUE_LENGTH.

3665 * expr.c (build_generalized_call): Add processing of
3666 BUILT_IN_QUEUE_LENGTH.
3668 * tasking.c (build_queue_length): New function.
3670 * tasking.c (tasking_init): Add new external function definition.
3672 Thu Sep 1 15:38:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3674 * lex.l (default_lex): New function. Progress towards
3675 getting rid of [f]lex.
3677 * lex.l (convert_number): Use mul_double and add_double.
3678 Set result type to a reasonable type in which the literal
3679 will fit. Give error message if literal is too big.
3681 * lex.l (equal_number): Switch (temporarily) to permanent obstack.
3683 * typeck.c (build_chill_slice_with_range): Check for empty
3684 slice *after* we have checked for upper/lower limit in range.
3686 * grant.c (decode_mode): Remove unused code. (BOOL and
3687 CHAR ranges are represented as INTEGER_TYPEs.)
3689 * tasking.c (build_process_header): Add missing call to
3690 expand_start_bindings.
3691 * parse.c (end_function): Add missing expand_end_bindings.
3693 Wed Aug 31 17:25:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3695 * decl.c (init_decl_processing): Set set_alignment.
3697 Tue Aug 30 16:40:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
3699 * actions.c (print_missing_cases, check_missing_cases,
3700 BITARRAY_TEST, BITARRAY_SET): New functions and macros,
3701 to check for completeness of case actions and expressions.
3702 * decl.c (c_decode_option, init_decl_processing):
3703 Don't set warn_switch.
3704 * expr.c (chill_expand_case_expr): Call check_missing_cases
3705 instead of check_for_full_enumeration_handling.
3706 * parse.c (parse_case_actions): Call check_missing_cases.
3708 * expr.c (build_chill_binary_op): Remove some dead code.
3709 * expr.c (chill_truthvalue_conversion): Call build_chill_binary_op
3710 instead of build_binary_op.
3711 * ch-tree.h (binary_op_error, build_binary_op): Unused. Removed.
3713 * parse.c (end_function): Use kept_level_p in parameter to
3714 poplevel. This reverts a June 13 change.
3716 Fri Aug 26 11:50:19 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3718 * configure: Ignore --without, as ../configure does.
3720 Wed Aug 24 01:17:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3722 * lex.l: Change rule for decimal numbers to allow identifiers
3723 to start with an underscore (_).
3725 Fri Aug 19 16:38:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
3727 * tasking.c (build_receive_signal_case_label): Remove backwards
3728 chill_convert_for_assignment (which converted whatever garbage
3729 was in the *target* to the type of the signal argument!).
3731 Fri Aug 19 07:10:43 1994 Wilfried Moser (moser@rtl.cygnus.com)
3733 * inout.c (build_chill_io_list_type, build_enum_tables),
3734 tasking.c (build_tasking_struct): Temporarily reset
3735 maximum_field_alignment to 0, so that the compiler-built
3736 data structures needed by the RTS can be independent of -fpack.
3738 Thu Aug 18 13:39:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3740 * typeck.c (build_init_struct): Temporarily reset
3741 maximum_field_alignment to 0, so that the compiler-built
3742 data structures needed by the RTS can be independent of -fpack.
3744 Wed Aug 17 23:48:33 1994 Wilfried Moser (moser@rtl.cygnus.com)
3746 * parse.c (parse_primval, expect, parse_on_exception_list):
3747 Print error message only in pass 2.
3749 Wed Aug 17 13:47:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3751 * decl.c (switch_to_pass_2): Revert June 13 change,
3752 (Don't exit after pass 1 if an error was found.)
3754 * ch-tree.def (SLICE_EXPR): New tree-code.
3755 * typeck.c (build_chill_slice): For building a slice of a
3756 bit-string, just generate a SLICE_EXPR.
3757 * decl.c (init_decl_processing): Declare __pscpy.
3758 * actions.c (chill_expand_assignment): Handle a SLICE_EXPR
3759 on the LHS of assignment, by calling __pscpy.
3760 * expr.c (chill_expand_expr): Handle SLICE_EXPR (as a RHS
3761 value) by using __psslice to copy slice to a temp.
3763 Wed Aug 17 05:52:44 1994 Wilfried Moser (moser@rtl.cygnus.com)
3765 * Make-lang.in: Change version of GNUCHILL compiler to 1.4.1.
3766 * expr.c (build_chill_length): Enable LENGTH built-in to process
3767 Buffers and Events too (Z.200/1992).
3768 * lex.l (yywrap): Always set yyin to finput and/or grt_in. On
3769 a linux system the previous version was not able to run.
3770 * tasking.c: Correct processing of infinite buffer- and event-length
3771 to avoid RANGEFAIL warning.
3773 Thu Aug 11 11:46:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3775 * parse.c (parse_if_expression_body): Don't call the C-specific
3776 build_conditional_expr. Just do build_nt (COND_EXPR, ...).
3777 * convert.c (convert): Convert a COND_EXPR by converting
3780 * convert.c (convert): Don't call convert before
3781 convert_to_reference. It's apt to do weird and unneedful things.
3782 * convert.c (convert): If the expression is varying, just call
3783 varying_to_slice, which simplifies quite a bit.
3785 * ch-tree.h (varying_to_slice): Add prototype.
3786 * typeck.c (varying_to_slice): Remove prototype.
3788 * satisfy.c (satisfy): Move case PAREN_EXPR from type 'e'
3791 * except.c (emit_setup_handler): Temporarily reset the
3792 maximum_field_alignment to zero so the compiler's exception
3793 data structures can be compatible with the run-time system,
3794 even when we're compiling with -fpack.
3796 * expr.c (compare_records): Call saved_if_needed on operands.
3798 * expr.c (build_set_expr case NE_EXPR): Don't use __nepowerset
3799 which has been reimplemented to just call __eqpowerset and
3800 invert the result. Inline this new implementation by
3801 handling as EQ_EXPR, and inverting the result.
3802 * decl.c (init_decl_processing): Don't define unused __eqpowerset.
3804 * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
3805 type boolean_type_node, not void_type_node. (Fixing this
3806 avoids a crash in the back-end.)
3808 * grant.c (decode_constant): In a CALL_EXPR, if the argument
3809 list is not a TREE_LIST (as in string repetiation), don't
3812 Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3814 * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
3815 CONST_DECL is from a SET definition. (This is safer than
3816 checking that the type is ENUMERAL_TYPE, because synonym
3817 definitions may have a NULL TREE_TYPE.)
3818 Also, if we have duplicate enums whose types are identical,
3820 * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
3821 an extra 'quiet' parameter, which is true if we're called from
3822 bind_sub_modules. (In that case an error message about duplicated
3823 decls would be repeated later, so suppress it.)
3825 * parse.c (stmt_count): Removed, not used.
3826 (INIT_ACTION): Call emit_line_note only if !ignoring.
3827 (parse_begin_end_block): Do INIT_ACTION even if ignoring.
3829 Fri Aug 5 12:39:11 1994 Per Bothner (bothner@kalessin.cygnus.com)
3831 * parse.c (parse_untyped_expr): Add missing semi-colon.
3833 Thu Aug 4 17:40:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
3835 * parse.c (parse_untyped_expr): Fix various problem for the
3836 case that we see a '(': Add missing 'case' keyword.
3837 Only recurse if '(' is followed by 'if', 'case' or '[',
3838 and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
3840 * parse.c (parse_send_action): Remove extra nreverse.
3842 Thu Jul 28 04:00:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3844 * expr.c (build_allocate_global_memory_call, build_allocate_memory_call):
3847 Tue Jul 26 22:48:15 1994 Michael Tiemann (tiemann@blues.cygnus.com)
3849 * parse.c (parse_untyped_expr): Added missing "case" before LPRN.
3850 Added a missing call to `require' as well.
3852 Tue Jul 19 10:30:12 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3854 * lex.l (yywrap): Define as yywrap_chill to avoid conflicts with
3855 the extern declaration in the flex skeleton.
3857 Mon Jul 18 23:06:04 1994 Per Bothner (bothner@kalessin.cygnus.com)
3859 * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
3860 Check the type of the instance expr using CH_COMPATIBLE,
3861 and not just == instance_type_node. (This allows
3862 the expression to have mode READ INSTANCE).
3863 * tasking.c (build_instance_type): Give instance_type_node
3864 a non-null novelty (i.e. different from a struct).
3865 * tasking.c (build_receive_case_start, build_delay_case_start):
3866 Check that for a location using CH_LOCATION_P.
3868 Mon Jul 18 13:22:23 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
3870 * expr.c (finish_chill_unary_op): Use TREE_SET_CODE not TREE_CODE
3871 to modify a tree code.
3873 Mon Jul 18 11:24:57 1994 Bill Cox (bill@rtl.cygnus.com)
3875 * convert.c (digest_structure_tuple): Fix thinko in TREE_CODE
3878 Mon Jul 18 05:40:15 1994 Doug Evans (dje@canuck.cygnus.com)
3880 * decl.c (warn_bad_function_cast): Define so cc1chill will link.
3882 Thu Jul 14 18:37:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3884 * parse.c (parse_send_action): Do tree_cons *before* checking
3887 Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3889 * convert.c (digest_structure_tuple): Don't use convert to
3890 coerce initial value, use chill_convert_for_assignment instead.
3891 (Thus we also get range_checking.)
3893 * expr.c (build_chill_card): Use force_addr_of instead of
3894 build_chill_addr_expr.
3896 * loop.c (build_temporary_variable): Stylistic tweak.
3897 * loop.c (maybe_make_for_temp): Initialize temp using
3898 explicitly, not using assignment. Avoids a problem if
3899 the expression is read-only.
3900 * typeck.c (smash_dummy_type): Always used the saved TYPE_NAME
3901 and CH_NOVELTY_FLAG.
3903 Wed Jul 6 20:12:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3905 * expr.c, ch-tree.h (finish_chill_unary_op): New function,
3906 based on code ripped out of build_chill_unary_op.
3907 (build_chill_unary_op): Call finish_chill_unary_op unless pass==1.
3908 * satisfy.c (satisfy): Call finish_chill_unary_op when needed.

3912 * tree.c (save_if_needed), ch-tree.h: New function.
3913 * typeck.c (build_chill_slice_with_range,
3914 build_chill_slice_with_length): Call save_if_neeed on array arg.
3915 * expr.c (varying_to_slice): Re-write to use save_if_needed.
3917 * typeck.c (extract_constant_from_buffer): Handle BOOLEAN_TYPE.
3919 Mon Jun 27 01:11:10 1994 Wilfried Moser (moser@rtl.cygnus.com)
3921 * inout.c (build_chill_io_list_type): Change layout of __tmp_WIO_list
3922 that it is always the same, regardless if compiled with -fpack
3925 Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3927 * lex.l (yywrap): Kludge to work around mis-synchronization
3928 between lexer (which read ahead) and parser: Don't emit
3929 (left-over) uze_seizefile directives at the end of file.
3931 * typeck.c (build_chill_array_ref): Allow the derived
3932 array indexing syntax for arrays of bit strings.
3933 Add a comment explaining why.
3935 * typeck.c, ch-tree.h (string_assignment_condition): Change
3936 the interface. Return a boolean expression (which can be
3937 used in a conditional at run-time); never expand anything.
3939 * actions.c (chill_convert_for_assignment): Check
3940 string_assignment_condition here, rather than in callers.
3941 * actions.c (chill_expand_assignment): Don't need to check
3942 string_assignment_condition here.
3943 * expr.c (build_chill_function_call): Likewise.
3944 * satisfy.c (safe_satisfy_decl): Update accordingly.
3945 * decl.c (do_decl): Simplify testing and conversion by
3946 deferring everything to chill_convert_for_assignment.
3948 * parse.c: Combine the two variables 'ignore_exprs' and
3949 'ignore_actions' into one variable called 'ignoring'.
3950 * ch-tree.h: Add 'extern int ignoring'.
3951 * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
3952 Rename ignore_actions and ignore_exprs to ignoring.
3953 Remove unneeded extern declarations.
3954 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3955 build_chill_arrow_expr, build_generalized_call, build_delay_action,
3956 build_buffer_type, build_event_type): I changed my mind. It is
3957 cleaner to check for 'ignoring' in the parser, rather than here.
3958 * parse.c (parse_action, parse_primval, parse_opt_mode):
3959 Therefore we must check for ignoring here.
3960 * parse.c (parse_loc_declaration): Set ignoring in pass 2
3961 when parsing the mode.
3963 * tasking.c (generate_tasking_code_variable): Do arithmetic
3964 on signal_code etc using unsigned rather than signed shorts.
3966 * grant.c (static char* current_grant_modename): Removed.
3967 * grant.c (decode_decl case CONST_DECL): Remove error message.
3969 * Make-lang.in (CHILL_SRCS): Add $(srcdir)/ch/parse.c.
3970 * Makefile.in: Fix dependencies for parse.o.
3971 Remove some duplicate dependencies for $(TREE_H).
3973 Mon Jun 13 14:25:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3975 * typeck.c (build_chill_cast): Allow a value cast between
3976 non-discrete object of the same size, but with a pedwarn.
3977 * typeck.c (bit_string_assignment_condition,
3978 char_string_assignment_condition): Merge near-duplicate functions
3979 and place the code in string_assignment_condition.
3981 * decl.c (parm_flag, declare_parm_level, in_param_level_p):
3983 * decl.c (start_chill_function, finish_chill_function): Make
3984 parameter level have same nesting level as body, as required by Z200.
3985 * decl.c (switch_to_pass_2): Always exit if an error has been found.
3986 * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
3987 generated from GRANT ALL.
3988 * decl.c (lookup_name_for_seizing): Don't seize from
3989 the nesting level of builtins (predefined objects).
3990 * decl.c (lookup_name_for_seizing): Make more robust on error.
3992 * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
3993 be 'RESULT' (or 'result'). This makes it more accessible from gdb.
3994 Also, use do_decl to declare it, so that debugging symbols are
3995 generated. And, re-arrange so that actions that need to
3996 be done both passes (such as push_levels) use the same code.
3998 * parse.c (get_type_of): If ignore_exprs, don't lookup name.
3999 * parse.c (end_function): Fix poplevel params.
4000 * parse.c (expect): Don't read forwards on an error.
4001 * parse.c (parse_field): Don't define two tag_list locals!
4002 * parse.c (parse_pass_1_2): Better error message.
4004 * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
4005 parse_opt_mode, rather than vice versa. If parse_opt_mode
4006 returns NULL_EXPR, then parse_mode gives an error.
4007 Change parse_opt_mode (and any functions it calls) to only
4008 return NULL_TREE if there is no mode (even on ignore_exprs).
4009 (parse_set_mode, parse_structure_mode, parse_procedure_mode):
4010 Never return NULL_EXPR.
4011 * tasking.c (build_buffer_type, build_event_type): Return
4012 void_type_node instead of NULL_EXPR if ignore_exprs is true.
4014 * parse.c (parse_synonym_definition): Call parse_untyped_expr
4015 only if we have a mode.
4016 * parse.c (parse_send_action): Parse list of untyped_expr's,
4017 rather than a list of (typed) expressions.
4018 * parse.c (parse_primval): Emit error if '[' seen without
4019 preceding mode name. (If this is to be allowed, call
4020 parse_untyped_expr instead.)
4022 * parse.c (parse_array_index): Renamed to ...
4023 (parse_index_mode): ... to match Z200 terminology.
4024 Re-write to resolve some of the nastier ambiguities,
4025 and allow things like ' CHAR(10) : CHAR(20) '.
4027 * parse.c (parse_tuple_element): Change interface to return
4028 reversed list, so don't call nreverse.
4029 * parse.c (parse_tuple): No longer nreverse element list here.
4030 * parse.c (parse_opt_element_list): Do nreverse here instead.
4031 * parse.c (parse_case_label_list): Call nreverse at end.
4033 Fri Jun 10 15:36:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
4035 * typeck.c (chill_similar): Remove bogus "else".
4037 Wed Jun 8 00:01:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
4039 * ch-tree.h (TYPE_ARRAY_MAX_SIZE): New macro (and comment)
4040 to make it clearer that we are using TYPE_MAX_VALUE in a special way.
4041 * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
4042 * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
4043 * convert.c (convert): When converting a fixed string/array
4044 to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
4045 of (the type of) the padding.
4046 * convert.c (convert): If the concatenation is non-constant, use
4047 the low-level 'build' to set the type of the result (which is usually
4048 a fixed-size array) rather than depend on build_chill_binary_op
4049 to figure it out (it's unable to simplify the size to a constant).
4051 Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
4053 * lang.c (lang_decode_option): Let -fspecial_UC imply
4054 -fno-ignore-case without requiring it explicitly.
4055 * lang.c (lang_decode_option): Support (experimentally)
4056 the -fpack and -fno-pack flags.
4058 Thu Jun 2 20:49:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4060 * configure: Add support for --program-prefix and --program-suffix.
4062 Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
4064 * convert.c (digest_constructor): Check that initial value
4065 is compatible with element mode before calling convert.
4066 * typeck.c (chill_compatible): A string mode is not compatible
4067 with an untyped constructor.
4068 * decl.c (do_decl): Clean up error messages. Use error_with_decl.
4070 * ch-tree.h: Fix inconsistencies: bool_true_node ->
4071 boolean_true_node, and bool_false_node -> boolean_false_node.
4072 * typeck.c (valid_array_index_): Minor simplification.
4074 Tue May 31 04:33:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
4076 * inout.c (build_chill_writetext): Add correct processing
4077 of POWERSET RANGE (setmode).
4079 * lex.l (same_file): Add searching for file(s) in
4082 Fri May 27 14:22:42 1994 Per Bothner (bothner@kalessin.cygnus.com)
4084 * Make-lang.c (CHILL.mostlyclean, CHILL.distdir): Don't list
4085 yacc/bison output files, since the grammer is no longer in yacc.
4086 * config-lang.in (diff_excludes): Likewise.
4088 Thu May 26 16:38:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
4090 * gperf, hash.h, lex.l, parse.h: Rename PROCESS_TYPE token
4091 (in some files spelled PROCESS_TYPE_ to avoid clashes
4092 with the PROCESS_TYPE tree_code) to PROCESS_TYPE_TOKEN.
4094 Thu May 26 02:18:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
4096 * timing.c (build_cycle_start): Change call to __define_timeout.
4097 * decl.c (init_decl_processing): Change definitions of
4098 __define_timeout and __wait_timeout.
4100 Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
4102 Replace yacc-based parser with a recursive-decent parser.
4103 (This may seem backwards, but Chill [like C++] is not a
4104 language that is remotely LALR(1). Using a R-D parser
4105 allows us to use look-ahead and to back-up to resolve the
4106 difficult ambiguities.)
4108 * parse.c, parse.h: New files, containing new r-d parser.
4109 * Makefile.in: Update accordingly.
4110 * actions.c (chill_convert_for_assignment): Don't return
4111 NULL_EXPR if ignore_exprs is true. It simplifies the parser
4112 if we consistently reserve NULL_EXPR for a missing expression.
4113 * expr.c (build_chill_function_call): Likewise.
4115 * lex.l: Tweaks for new parser.
4116 * lex.l (prepare_paren_colon, paren_paren_colon_level,
4117 paren_level): Ugly hack no longer needed.
4119 * expr.c (build_chill_function_call): Cleanup.
4120 Call chill_convert_for_assignment to convert IN/INOUT
4121 paramaters on both input and output. For LOC parameters,
4122 give error if actual is a non-referable location.
4123 * actions.c (convert_for_assignment): Add new parameter (a
4124 "place" string used in error messages).
4125 * actions.c (adjust_parm_or_field): Removed.
4126 * actions.c (chill_expand_assignment): Take just a single LHS,
4127 and move support for multiple assignments to ...
4128 (expand_assignment_action): ... here. Some cleaning up.
4129 * timing.c (build_cycle_start): Adjust accordingly.
4130 * actions.c (expand_assignment_to_varying_array): Likewise.
4131 * tasking.c (many places): Ditto.
4132 * ch-tree.h: Fix declarations appropriately.
4134 * parse.c (parse_defining_occurrence_list): Return a single
4135 IDENTIFIER_NODE (instead of a singleton list) in the common
4136 case. Minor complication to save a minor amount of space.
4137 * decl.c (do_based_decls): Move guts of code into ...
4138 (do_based_decl): ... this new function.
4139 * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
4140 * decl.c (push_syndecl): Replace by ...
4141 (push_syndecl): ... (which only supports a single name).
4142 (push_modedef): Only handle a single name.
4143 * tasking.c (build_process_header, build_signal_struct_type):
4146 * expr.c (build_generalized_call): Handle string repetition.
4147 * expr.c (build_chill_repetition_op): Change interface.
4148 * grant.c (decode_constant): Allow parameter list to be
4149 a non-TREE_LIST. (Used for string repetition.)
4151 Wed May 25 11:28:48 1994 Per Bothner (bothner@kalessin.cygnus.com)
4153 * lex.l (make_identifier): Replaced by ...
4154 (read_identifier, handle_name): ... new functions.
4155 * lex.l: Parse an identifiers using read_identifier using
4156 read_identifier and handle_name, rather than having [f]lex
4157 do it. (One reason is that lex uses a fixed-size buffer.)
4159 * lex.l (read_directive, skip_directive): New functions.
4160 Use them to parse compiler-directives, instead of rather
4161 ugly and useless use of lexer start conditions.
4163 Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4165 * decl.c (unnamed_module_number): Renamed to ...
4166 (module_number): .. and make non-static.
4167 (push_module): Always increment module_number.
4168 * lex.l (yywrap): Print warning if no modules seen.
4170 * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
4171 decl to current_seizefile_name (which is unreliable).
4172 * grant.c (chill_grant): Set it here instead.
4174 * expr.c (fold_set_expr): Use int_size_in_bytes instead of
4175 TYPE_PRECISION (which is not defined for a SET_TYPE).
4177 Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
4179 Cleanup to remove need for variables in common storage.
4180 * decl.c: Remove unused use of current_obstack.
4181 * actions.c (maybe_chill_check_decl): Remove unused function.
4182 * actions.h, lang.c: Remove uses of doing_chill_thang.
4183 * ch-tree.h (void_list_node): Make extern (rather than common).
4184 * decl.c (void_list_node): Add definition.
4186 Thu May 19 06:54:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
4188 * configure (build): Build canon_host and canon_target
4189 to pass it to all subsequently generated Makefiles (needed
4190 for testsuite/execute in case of cross build).
4192 Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4194 * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
4195 the input type, which loses with the no-longer-new 2-pass
4196 implementation, since the input "type" could be an IDENTIFIER_NODE.
4197 * grant.c (raw_decode_mode): Rename to decode_mode.
4199 Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
4201 * typeck.c (chill_location): Neither a STRING_CST nor a
4202 CONSTRUCTOR is a location.
4203 * typeck.c (chill_root_mode): Convert a function to a
4204 pointer-to-function.
4205 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
4206 build_chill_arrow_expr): If ignore_exprs, return operand
4207 rather than NULL_EXPR. This makes it easier for the parser to
4208 distinguish missing expressions.
4209 * expr.c (build_max_min): Convert the lower bound of a
4210 set to a long before calling run-time routine.
4211 * expr.c (build_chill_pred_or_succ): Use discrete_type_p
4212 to check the argument type.
4213 * expr.c (build_chill_arrow_expr): If argument is not a location,
4214 do a predwarn if it is a STRING_CST or has function type.
4216 Tue May 17 06:05:13 1994 Wilfried Moser (moser@rtl.cygnus.com)
4218 * configure (build): Remove building of canon_host and canon_target.
4219 It doesn't work in any case.
4221 Mon May 16 02:10:35 1994 Wilfried Moser (moser@rtl.cygnus.com)
4223 * configure (build): Build canon_host and canon_target
4224 to pass it to all subsequently generated Makefiles (needed
4225 for testsuite/execute in case of cross build).
4226 * Make-lang.in (chill-runtime): Change chill to CHILL in the case
4227 statement to build chill-runtime automatically.
4229 Mon May 9 15:30:08 1994 Doug Evans (dje@canuck.cygnus.com)
4231 * Makefile.in (FLAGS_TO_PASS): Define.
4233 (../cc1chill): Depend on $(OBJDEPS) $(C_OBJS).
4234 * Make-lang.in (cc1chill): Delete dependency on $(OBJS) $(BC_OBJS).
4235 (CHILL.mostlyclean): Use `mostlyclean' as recursive target.
4237 Sun May 8 13:05:00 1994 Per Bothner (bothner@cygnus.com)
4239 * Make-lang.in (cc1chill): Should not depend on libgcc.a.
4241 Thu May 5 18:58:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
4243 * decl.c (copy_lang_decl): New (dummy) function.
4245 Mon May 2 14:33:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
4247 * parse.y (sendaction): Fix thinko (in sense of condition).
4248 * tasking.c (build_receive_case_label): Another thinko.
4250 * parse.y (optsigdest): Force ignore_exprs to 0 while parsing
4253 * decl.c (build_chill_function_type): Don't call layout_type
4254 (since that may prevent parameter or result types being
4255 properly satisfied).
4256 * satisfy.c (satisfy): Layout FUNCTION_TYPEs.
4257 * parse.y (procmode): Call build_chill_pointer_type, rather
4258 than build_pointer_type (which incorrectly sets TYPE_SIZE).
4260 * parse.y (get_type_of): Handle TYPE_DECL (again).
4261 * parse.y (optresultspec): Call build_chill_reference_type, rather
4262 than build_reference_type (which incorrectly sets TYPE_SIZE).
4263 * parse.y (range_or_mode): Rename to plain range, since it
4264 no longer matches modename.
4265 * actions.c (chill_handle_case_label_range): New function, with
4266 functionality moved out of chill_handle_case_label.
4267 * actions.c (chill_handle_case_label): Handle here the case that
4268 the label_value is a TYPE_DECL (modename). Also clean up some.
4269 * typeck.c (build_chill_slice_with_length): Convert max_index
4270 to the type of min_value. (Old code broke on varying strings.)
4272 Sun May 1 13:53:36 1994 Doug Evans (dje@canuck.cygnus.com)
4274 * Makefile.in (BC_OBJS): Delete all references
4275 (OBJS): Cat ../stamp-objlist to get language independent files.
4276 (../cc1chill): Delete dependency on $(OBJS).
4277 * Make-lang.in (cc1chill): Depend on stamp-objlist.
4279 Sat Apr 30 14:50:15 1994 Per Bothner (bothner@kalessin.cygnus.com)
4281 * lex.h, lex.c: Remove lastiddecl.
4282 * lex.l (name_type_signal): Simplify. We no longer check for
4283 TYPENAME or SIGNALNAME (which was unreliable with two passes).
4284 Also rename to make_identifier.
4285 * parse.y: Cleaned up grammar to not need SIGNALNAME or TYPENAME.
4286 * Makefile.in (stamp-parse); One conflict fewer!
4287 * parse.y (rccase_label_flag): Moved to tasking.c.
4288 * parse.y (rccase_label): Move most of the logic to
4289 build_receive_case_label in tasking.c.
4290 * parse.y (sendaction): Re-write to not depend on SIGNALNAME.
4292 * parse.y (name): Do name lookup here (and not in location).
4293 * parse.y: Replace most uses of NAME by higher-level non-terminals:
4294 simple_name_string, name_string, defining_occurrence, or name.
4296 * tasking.c (build_receive_signal_case_label,
4297 build_receive_buffer_case_label): New functions, split out from
4298 build_receive_case_label.
4299 * tasking.c (build_receive_case_label): Change parameters
4300 and return type. Moved stuff here (from the parser).
4301 * tasking.c (struct rc_state_type): Removed had_errors.
4302 Return error_mark_node instead.
4303 * tasking.c (build_rccase_set_error), ch-tree.h: Removed.
4305 * expr.c (build_generalized_call): If func is a signal type,
4306 call build_signal_descriptor.
4308 * parse.y (arrayindex): Renamed to index_mode, to match Z.200.
4309 * parse.y (ioindexmode): Removed; use index_mode instead.
4310 * expr.c (build_generalized_call): If args is a RANGE_EXPR,
4311 we have either a slice or a range mode, depending on func.
4312 * parse.y (index_mode): If we got an 'expr', only allow a name,
4314 * parse.y (call): A slice with both end points can be a range
4315 mode, so defer handling to build_generalized_call (or index_mode).
4317 * typeck.c (build_chill_slice_with_length): Fix type-checking.
4318 * typeck.c (chill_novelty): Undo (part of) change of April 28:
4319 The novelty of a range mode is the novlety of the parent.
4320 * typeck.c (chill_root_mode): Don't return integer_type_node
4321 if argument has non-nil novelty.
4323 * decl.c (global_bindings_p): Return -1 as true, for the sake
4324 of variable_size (in ../stor-layout.c).
4326 Fri Apr 29 13:42:43 1994 Per Bothner (bothner@kalessin.cygnus.com)
4328 * parse.y: Remove TYPENAME and modename. These are now plain
4329 NAMEs. Modify parsing actions appropriately.
4330 * expr.c (build_generalized_call): Handle the case that
4331 TREE_CODE (func) == TYPE_DECL (as in a cast).
4332 * lex.l (name_type_signal): Never return TYPENAME.
4333 * parse.y (get_type_of): If pass 1, just return the argument.
4335 * decl.c (do_decl): If an initializer has the wrong type,
4336 replace it by NULL_TREE, to avoid subsequent errors.
4338 Thu Apr 28 15:21:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
4340 * Makefile.in: Add new file timing.c to rules.
4341 * timing.c: New file. Implements the timing actions AT,

4345 * expr.c (build_chill_indirect_ref): Change error message and
4346 add check agains an IDENTIFIER_NODE.
4347 * gperf, hash.h: Change EVENT_CODE, BUFFER_CODE to IGNORED_DIRECTIVE.
4348 They are no longer needed.
4349 * grant.c (print_integer_type): Add processing of builtin types
4351 * lex.l: Remove processing of directive EVENT_CODE & BUFFER_CODE.
4352 * parse.y (timingactions): split up to afteraction, ataction
4354 * parse.y (afteraction): New rule.
4355 * parse.y (ataction): New rule and put actions in.

4366 * tasking.c (build_receive_case_label): Add processing of BUFFER's.
4367 * tasking.c (build_receive_buffer_case_end, build_receive_signal_case_end):
4368 New functions to process the end of a RECEIVE CASE action in case
4369 of BUFFER's and SIGNAL's.
4370 * tasking.c (build_receive_case_end): Do only general processing and
4371 call one of the above mentioned functions.
4372 * tasking.c (build_delay_case_start, build_delay_case_label,
4373 build_delay_case_end): Rewritten due to new implementation of events.
4374 * tasking.c (build_delay_action): Rewritten due to new implementation

4380 Thu Apr 28 14:11:29 1994 Per Bothner (bothner@kalessin.cygnus.com)
4382 * typeck.c (smash_dummy_type): Handle the special case of a
4383 NEWMODE of a range mode, as required by Z200, by creating a
4384 new parent mode with the new novelty (and casting the min
4385 and max of the range to teh new parent mode).
4386 * typeck.c (chill_novelty, chill_root_mode): Remove special
4387 kludges for of NEWMODE ranges.
4388 * expr.c (build_chill_lower_or_upper): New function, combining
4389 the "guts" of build_chill_lower and build_chill_upper.

4391 need to kludge the novelties.
4393 * typeck.c (valid_array_index_p): A string index expression
4394 need not be Compatible with the index type; only similar.
4396 * decl.c (layout_chill_variants): If error seen, skip stuff

4429 * grant.c (set_use_this_gf): Removed.
4430 * grant.c (set_default_grant_file): Set grant_file_name here,
4431 because we need it earlier (due to above lexer change).

4527 * actions.c (chill_expand_assignment): Check for compatibility
4528 _after_ "expanding out" a binary operation. This fixes
4529 the case "STRING //:= CHAR".

4780 to be compatible with the N-value class, with suitable M and N.
4781 * typeck.c (build_chill_slice): Don't smash a void TREE_TYPE.

4784 * expr.c (build_compare_expr): Fix thinko. Add save_exprs.
4786 * expr.c (build_compare_expr): Fix a transcription bug
4787 (for converting NULL INSTANCEs). Also #include convert.h.

4818 to have consistent operand types.
4819 * typeck.c (valid_array_index_p): Change interface to pass
4820 validity conditions back on caller's TREE_LIST. We
4821 cannot link the conditions to anything which a
4822 layout_type routine will expand, since that will occur
4823 before the exception handler is set up.
4824 Change calls to valid_array_index_p also.

4839 * typeck.c, ch-tree.h (build_chill_slice): Make non-static.
4840 * expr.c (varying_to_slice): Call build_chill_slice (and not
4841 build_chill_slice_with_length, which does bunches of range
4842 checking and does not allow the length to be zero).

4848 * decl.c (init_decl_processing): __lepowerset and __ltpowerset
4849 take *two* pointer parameters, not one.
4850 * satisfy.c (satisfy): Only call the appropriate layout routine
4851 if TYPE_SIZE is 0 (i.e. type hasn't already been laid out).
4852 * typeck.c (build_chill_slice_with_length): Fix Bill's previous fix.
4854 Thu Mar 17 17:29:43 1994 Bill Cox (bill@rtl.cygnus.com)
4856 * expr.c (build_chill_function_call): Give function call the correct
4858 * typeck.c (build_chill_slice_with_length): Restore dynamic range
4859 checking, so it doesn't obscure the CONSTANTness of the length.
4861 Wed Mar 16 17:23:31 1994 Per Bothner (bothner@kalessin.cygnus.com)
4863 * typeck.c (build_chill_slice), expr.c (chill_expand_expr
4864 [case CONCAT_EXPR]): Remove kludge setting slice size upper bound
4865 in TYPE_LANG_SPECIFIC, and restore kludge setting it in MAX_VALUE.
4866 * typeck.c (build_chill_slice): Use TYPE_MAX_VALUE of
4867 array_type if needed for size upper bound of slice_type.
4868 * expr.c (build_concat_expr): Improve calculation of size upper bound.
4870 * typeck.c (valid_array_index_p): Check compatibility using
4872 * typeck.c (build_chill_slice_with_length); For now revert
4873 calling valid_array_index_p on length. (It makes it harder
4874 to realize when the slice is constant length.)
4875 * expr.c (build_chill_indirect_expr): Minor tweak. (This
4876 seems to work around a weird C compiler bug. ??)
4878 * expr.c (build_chill_function_call): Cleanup so it doesn't
4879 call build_function_call (in c-typeck.c).
4880 * typeck.c, expr.c: Use build_chill_function_call instead of
4881 build_function_call (in c-typeck.c).
4883 * parse.y (discrete_mode): Move some of the rules from
4884 non_array_mode into new non-terminal.
4885 (arrayindex): Use discrete_mode (with NAME and TYPENAME) to
4886 avoid some misparses.
4887 * ch-tree.h (SLICE_PTR, SLICE_LENGTH): Removed; unused.
4888 * convert.c (digest_structure_tuple): Add missing parameter.
4889 * decl.c (comptypes): Remove unused prototype.
4890 * decl.c (build_chill_function_type): Handle NULL return_type
4891 correctly (convert to void_type_node).
4892 * decl.c (init_decl_processing): layout boolean_type_node *after*
4893 we've set it's TYPE_MIN_VALUE and TYPE_MAX_VALUE.
4895 Wed Mar 16 16:08:22 1994 Bill Cox (bill@rtl.cygnus.com)

4898 * convert.c (convert): Correct calculation of padding length.
4899 * decl.c (grok_chill_fixedfields): Move ignore_exprs test to
4900 parse.y where it belongs. This permits the removal of a kludge
4901 in make_process_struct.
4902 * lex.l, parse.y: Call to_global_level for several errors. Add
4903 code to output error in only one pass.
4904 * tasking.c (make_process_struct): Delete kludge inserted on

4911 (build_rts_call): Ifdef it out - never used.
4912 (expand_varying_length_assignment): call valid_array_index_p.
4913 rather than validate_varying_array_ref.
4914 * ch-tree.h: Fix prototype for valid_array_index_p.
4915 * expr.c (chill_expand_expr): Call build_chill_array_ref to get
4917 (build_hill_lower, build_chill_upper): Return value now inherits
4918 the novelty of the input parameter.
4919 (varying_to_slice): Use CH_NOVELTY macro rather than calling
4920 chill_novelty directly.
4921 * grant.c (newstring): Make len unsigned and cast xmalloc parameter
4923 (print_integer_type): Pass string value as APPEND's second parameter.
4924 (decode_decl): Pass a boolean expression as print_proc_tail's
4926 (chill_finish_module_code): Make xmalloc's parameter unsigned.
4927 * lex.l: Pass sizes to xmalloc as unsigned ints. Pass second
4928 parameter to in_word_set as unsigned.
4929 * loop.c (build_loop_start): Check top_loop_end_check return value.
4930 * parse.y: Add casts to int for third do_decls parameter, fifth
4931 build_loop_iterator parameter, etc.
4932 * tasking.c (build_receive_case_end): Chack cond_stack before popping.
4933 * typeck.c (validate_varying_array_ref, chill_max_vary_array_index,
4934 valid_array_index): Delete them. They're now unused.
4935 (valid_array_index_p): Add function, call it everywhere that an
4936 array index is checked.
4937 (build_chill_slice): Restore old functionality where varying_to_slice
4938 is called to handle slices of varying arrays, rather than handling
4940 (build_chill_slice_with_range, build_chill_slice_with_length):
4941 Check range limits for TREE_CONST before calling tree_int_cst_lt.
4942 Delete now-obsolete checks of constant indices.
4944 Mon Mar 14 17:26:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4946 * parse.y (modeless_expr): New rule to allow ([...]) and (if...)
4947 to count as untyped_exprs. (This is not really permitted by the
4948 Blue Book, but has been requested by customers.)
4950 Thu Mar 10 10:11:02 1994 Bill Cox (bill@rtl.cygnus.com)
4952 * chill.texi: Document new command-line options.
4953 * expr.c (build_chill_num): Set unsigned parameter for

4956 enable/disable runtime range-checking.
4957 * lex.l: Eat more whitespace.
4959 Thu Mar 10 09:41:37 1994 Bill Cox (bill@rtl.cygnus.com)
4961 * Makefile.in: Have rules to make parse.h, y.tab.c and other
4962 derived files. This allows the gcc/configure list of CHILL
4963 files machinery to work.
4964 * ch-tree.h (permanent_allocation): Add a parameter flag.
4965 * decl.c (finish_chill_function, finish_decl): Provide the
4966 new permanent_allocation flag.
4967 (poplevel): Return early, avoid a seg fault.
4968 * lex.l (NORMAL): Replace this whole state with the predefined
4969 INITIAL state. Force compilation state to global level after
4970 compiler directive error - prevents endless loop on error.
4971 (handle_use_seizefile_directive): Rewrite for readability.
4972 (chill_same_grant_file): Reindent.
4973 Generally handle whitespace differently.
4974 * regression.prpt: Print ten PR numbers per line. The report's

4979 * decl.c (do_decl): Suppress the string-assignment-condition
4980 error - it was too often seen.
4981 * expr.c (expand_chill_expr): In CONCAT_EXPR, when argument has a
4982 runtime-changing length (as in a slice), get the parent array's
4983 allocation size from its type tree.
4984 * typeck.c (build_chill_slice): Support VARYING arrays. Pass
4985 parent array's static allocation size along in the slice type.
4987 Wed Mar 9 08:54:24 1994 Bill Cox (bill@rtl.cygnus.com)
4989 * lex.l (name_type_signal): Avoid dereferencing a NULL TRE_TYPE.

4993 * expr.c (build_chill_sizeof): Fix typo in error msg, add
4995 * lex.l (name_type_signal): Add debug output.
4996 * parse.y (call): Allow EVENTNAME and BUFFERNAME parameters
4997 to a call, so that SIZE () works on them.
4998 * tasking.c (make_process_struct): Force ignore_exprs non-zero
4999 when processing a SEIZEd PROCESS declaration. This prevents
5000 grox-fixed_fields from returning a NULL, and indirectly protects
5001 the chill_integer_type_node tree from corruption.

5005 * Makefile.in: Use the 'all' target to build the runtime
5006 library and chillrt0.o.

5009 chill.regress.cron: Move to utils subdirectory.
5010 * expr.c (build_chill_function_call): Mark the INOUT
5011 temporary so it doesn't get optimized into a
5012 register. Fixes the execute/inout.ch bug.
5013 * typeck.c (layout_chill_range_type): Restrict it
5014 from complaining about an empty string type's
5017 Mon Mar 7 09:06:39 1994 Bill Cox (bill@rtl.cygnus.com)

5050 * lex.l (INITIAL): Remove all code to discard 'header lines'.
5052 * parse.y (optheader): Remove - it's obsolete, as is the
5053 HEADEREL token definition.
5055 Fri Mar 4 09:41:18 1994 Bill Cox (bill@rtl.cygnus.com)
5057 * addtest: Fix suffix removal when suffix is .c186.

5152 name for correctness.
5154 Wed Feb 23 15:07:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
5156 New cleaner solution to the following problem:
5157 Chill allows an action to be followed by an ON-handler.
5158 But we don't know if an action has a handler until we've parsed
5159 its end, yet we want to generate extra code to set up an
5160 exception handling contour only if needed. The old solution
5161 would generate code for the action into an rtl sequence, and then
5162 splice in the exception-setup code if we later found we needed it.
5163 This has a few problems (for example it confuses the management
5164 of stack temporaries), and is ugly. Now that the compiler is 2-pass
5165 we have a cleaner solution: In pass 1, we remember which actions
5166 were followed by ON-handlers. In pass 2, we use this information
5167 to generate appropriate code before an action.
5168 * except.c (push_handler, pop_handler): In pass 1, set up data
5169 structures (global_handler_list) to remember if an action has an
5170 ON-handler. In pass 2, digest this information, and setup
5172 * except.c, actions.h (pop_handler): Take an extra int arg.
5173 * except.c (emit_setup_handler): New function, with code (moved
5174 from chill_start_on) to emit code before an action that has a handler.
5175 * except.c (except_init_pass_2): New function.

5177 * parse.y (POP_UNUSED_ON_CONTEXT): Don't call pop_sequence.
5178 * parse.y: Invoke POP_UNUSED_ON_CONTEXT and POP_USED_ON_CONTEXT
5179 in pass 1 as well as pass 2.
5180 * parse.y (BEGIN ... END): Re-arrange logic to avoid block_stack
5181 (local to ../stmt.c) getting out of sync.
5182 * actions.c (push_action): Don't need to emit a NOP,
5183 now that we're no longer moving sequences around.
5184 * actions.c (push_action): Call push_handler even in pass one.
5186 Wed Feb 23 11:06:14 1994 Bill Cox (bill@rtl.cygnus.com)

5288 if TREE_TYPE has not been laid out.
5289 * typeck.c (build_chill_array_type): Update accordingly.
5290 * typeck.c (build_chill_slice): Replace calls to build_array_type

5293 * convert.c (convert): The same.
5295 * grant.c (decode_constant): Clean up. Remove remnants of switch

5815 * ch-typeck.c (build_chill_array_ref_1), ch-tree.h: New function
5816 which does the actual work for build_chill_array_ref (which
5817 now just loops over an argument list).
5818 * ch-actions.c, ch-expr.c, ch-inout.c: Use build_chill_array_ref_1
5819 instead of build_chill_array_ref where appropriate.
5820 * ch-actions.c, ch-expr.c, ch-typeck.c: Make operand 1 of a
5821 VARY_ARRAY_REF is a single index, not an index list.
5823 * ch-grant.c (__init_list): Renamed to _ch_init_list, to
5824 avoid a conflict on the Alpha.
5826 Wed Jan 12 10:19:35 1994 Bill Cox (bill@rtl.cygnus.com)
5828 * ch-lex.l (WS): Add BS, VT and CR to definition of
5830 (convert_number): Allow for uppercase hex digits.

5835 conditional so error messages are output.
5836 * ch-expr.c (build_chill_addr_expr): Add error message.
5837 * ch-grant.c (chill_finish_module_code): Avoid abort by
5838 giving the init_list constructor a type.
5839 (chill_finish_compile): Delete unused code.
5840 * ch-lex.l: Make most build_init_2 calls from the
5841 permanent obstack, so that enumeration values endure.

5848 'struct ch_class class = chill_expr_class (expr);' to
5849 'struct ch_class class; class = chill_expr_class (expr);'
5850 to work around a bug in /usr/ucb/cc on SunOS4.
5852 Mon Jan 10 18:29:36 1994 Bill Cox (bill@rtl.cygnus.com)
5854 * ch-actions.c (chill_convert_for_assignment): Avoid seg fault.
5855 * ch-expr.c (expand_packed_set): Add new parameter to pass

5875 Also, fix some bugs for bitstrings (with ranges).
5877 (Patches from Tiemann.)
5878 * ch-convert.c (convert1): New function to force TREE_TYPE.
5879 (convert): Use convert1 where appropriate.
5880 * ch-typeck.c: Formatting change.
5881 * ch-parse.y (build_chill_constructor): Fix thinko.
5883 * ch-expr.c (varying_to_slice): If array is not referable,
5884 call save_expr on it, rather than stabilize_reference.
5885 * ch-satisfy.c (safe_satify_decl, for CONST_DECL):
5886 Don't force value to value class if mode is not explicitly
5887 specified. Also, make sure convert etc is only done once.
5889 Sat Jan 8 16:37:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
5891 * ch-decl.c (build_chill_function_type): Don't call
5892 build_function_type, because it does hash canonicalization,
5893 which once in a while looses badly.

5895 for doing_chill_thang.
5897 * ch-tree.h (CH_DERIVED_FLAG): New flag.

5911 convert_float, convert_number): Set CH_DERIVED_FLAG for literals.
5912 * ch-expr.c (finish_chill_binary_op): Use convert_to_class.
5913 * ch-satisfy.c (safe_satisfy_decl): For CONST_DECL, make sure
5914 DECL_INITIAL gets set to result of convert.
5915 Also, clear CH_DERIVED_FLAG for SYN value.
5916 * expr.c (store_constructor): If a [power]set is exactly one
5917 word long, use single-word move.
5919 Sat Jan 8 08:38:29 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5921 * c-typeck.c (chill_initializer_constant_valid_p): Fix typo.

5934 for unary set operations).
5936 * ch-expr.c (build_chill_array_expr): Take new argument FORCE. All
5937 callers changed. All callers changed.
5939 * ch-convert.c (digest_structure_tuple): Handle SELECTED_VARIANT
5940 being NULL_TREE until we've started walking the list of values via
5941 the loop over VARIANTs.
5943 * ch-parse.y (build_chill_constructor): If we see an IDENTIFIER_NODE,
5944 treat it as an enum value (and hence constant). Also, only set
5945 TREE_STATIC if the constructor is indeed constant.
5946 * c-typeck.c (chill_initializer_constant_valid_p): If we see a
5947 VAR_DECL, test the TREE_CONSTANT field of the DECL_INITIAL, don't
5948 recurse on the DECL_INITIAL.
5950 Wed Jan 5 01:24:50 1994 Bill Cox (bill@cygnus.com)
5952 * Makefile.in: Add CHILL to LANGUAGES variable.
5953 * ch-actions.c (check_range): Call build_binary_op instead of
5954 fold, build to get the common types chosen.
5955 (cond_range_exception, cond_overflow_exception,
5956 cond_type_range_exception): Delete, obsolete.
5957 (chill_convert_for_assignment): Enable this, get particular
5958 about when to generate rangecheck code.
5959 * ch-expr.c (build_chill_function_call): Sketch in where to
5960 perform chill_convert_for_assignment on actual parameters.
5961 (build_chill_addr_expr): Correct compiler warning.
5962 * ch-loop.c (build_chill_iterator): Add runtime check for
5963 negative loop step expression.
5964 * ch-tree.h: Add prototype.
5965 * ch-typeck.c (chill_max_vary_array_ref): Correct misunderstanding.
5966 A varying array's length field counts the NUMBER of active array
5967 array entries, not the byte-length of them.
5969 Tue Jan 4 17:57:39 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5971 * ch-decl.c (do_decl): Call `suspend_momenary' if the
5972 converted constructor must live on the permanent_obstack.
5973 * ch-convert.c (convert): When building a new SET_TYPE
5974 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5975 * c-typeck.c (chill_initializer_constant_valid_p): Handle VAR_DECLs.
5977 * ch-typeck.c (chill_location): CONSTRUCTORS that are static

5980 on permanent_obstack if necessary.
5982 * ch-convert.c (digest_structure_tuple): When building a new SET_TYPE
5983 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5985 * ch-decl.c (do_decl): Fix handling of REFERENCE_TYPEs which

5988 * ch-expr.c (build_chill_arrow_expr): Call `mark_addressable'.
5989 (build_chill_addr_expr): Take new argument ERRORMSG.
5990 All callers changed. Also, call `build_chill_addr_expr' where
5991 we used to call `build1 (ADDR_EXPR, ptr_type_node, ...)' since
5992 that now calls `mark_addressable' automagically.
5994 * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.
5995 This is needed because variables may appear in initialization
5996 statements, and their DECL_INITIALs are their values at
5997 initialization time.
5998 * ch-convert.c (digest_structure_tuple,digest_constructor): Changed
5999 to handle VAR_DECLs as initializers.
6001 * ch-convert.c (digest_structure_tuple): Copy elements of INITS so
6002 they aren't destroyed for later use.
6004 Tue Jan 4 15:25:30 1994 Bill Cox (bill@cygnus.com)
6006 * ch-expr.c (chill_expand_expr): Correct check-range lo_limit
6007 parameter for varying_array_ref calculations.
6008 (build_chill_indirect_ref): Prevent seg fault due to syntax error.
6009 * ch-typeck.c (build_chill_slice_with_range): Correct issuance
6010 of bogus error in votrics.
6011 (build_chill_slice_with_length): Change for debug tracability.

6015 * ch-convert.c (digest_structure_tuple): Fix phasing problem in
6016 handling variant record initializers.
6017 (various places): Change `pop_init_level' calls to match
6018 `push_init_level' wrt implicit variable.
6020 * ch-typeck.c (build_chill_slice): Convert the dynamic max index to
6021 `integer_type_node' before using it in comparisons. FIXME: should
6022 this be done in `chill_max_vary_array_index' by default?
6024 Tue Jan 4 00:24:14 1994 Bill Cox (bill@cygnus.com)
6026 * ch-actions.c: Fix comments.
6027 * ch-parse.y: Define caseaction_flag.
6028 (caseaction): Create new caseaction_flag node at the start,
6029 then free it at the end. Check it before the ELSE code.
6030 (expanded_case_label): Check the flag here. If set in either
6031 place, generate a jump to the end of the case.
6032 * ch-typeck.c (build_chill_slice_with_length,
6033 build_chill_slice_with_range): Add lots of compile-time
6034 parameter range checking.
6036 Mon Jan 3 21:49:04 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6038 * ch-convert.c (digest_structure_tuple): Call `push_init_level' with
6039 implicit==0 everywhere, not 1.
6040 (digest_constructor): Ditto.
6042 * ch-actions.c (check_range): Permit limits to be NULL_TREE.
6043 Also, hack out some dead code.
6044 * ch-typeck.c (build_chill_slice): Check varying and non-varying
6045 slice constructs for range failures.
6046 (build_chill_slice_with_range): Reindented, but not changed.
6048 * ch-typeck.c (chill_max_vary_array_index): New function.
6049 * ch-expr.c (chill_expand_expr): Call it.
6051 * ch-decl.c (var_data_id, var_length_id): New variables.
6052 (init_decl_processing): Initialize them. All calls to
6053 get_identifier (VAR_LENGTH or VAR_DATA) are now replaced
6054 by references to these variables. This simplifies the code
6055 w/o obscuring anything.
6057 Mon Jan 3 21:24:44 1994 Bill Cox (bill@cygnus.com)
6059 * c-typeck.c: Fix comment.
6060 * ch-actions.c (chill_expand_assignment): Error assigning to
6061 READONLY location. (PR_3903) Pass filename, linenumber
6062 to setbitpowerset runtime routine.
6063 * ch-decl.c (init_decl_processing): Add filename, linenumber
6064 parameters to setbitpowerset prototype.
6065 * ch-expr.c (build_chill_function_call): Error when passing a
6066 READonly location as a LOC or INOUT parameter.
6067 * ch-parse.y (mode): Correct code marking type as readonly.
6069 Mon Jan 3 19:03:55 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6071 * ch-actions.c (chill_expand_assignment): Disable code that defeats
6072 building varying array references.
6073 * ch-expr.c (chill_expand_expr): Add rangecheck code to
6074 VARY_ARRAY_REF case.
6075 * ch-typeck.c (build_chill_array_ref): Don't call an `expand_'
6076 function (in this case, `validate_varying_array_ref') when we're
6077 doing a `build_' operation.
6079 * ch-typeck.c (validate_varying_array_ref): Simplify interface
6080 since INDEX parameter can never meaningfully be an INDEXLIST.
6081 * ch-actions.c (expand_varying_length_assignment): Caller changed.
6083 Mon Jan 3 07:29:45 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6085 * ch-typeck.c (build_chill_cast): Set TREE_CONSTANT on NOP_EXPRs.
6086 * ch-convert.c (digest_structure_tuple): Switch to permanent_obstack
6087 if we need to build a CONSTRUCTOR for a SET_TYPE initializer.
6088 (digest_structure_tuple): If TREE_VALUE (VALUE) == NULL_TREE, don't
6089 call CH_COMPATIBLE or try to convert it to TREE_TYPE (FIELD). This
6090 can happen when constructors are output incrementally.
6091 * c-typeck.c (initializer_constant_valid_p): Handle SET_TYPEs.
6092 * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
6095 Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6097 * ch-convert (digest_structure_tuple): Handle SET_TYPEs. Also, call
6098 `convert' so we can handle INSTANCE types (and other anomolies)
6101 * ch-convert.c (digest_structure_tuple): Fixed variant
6102 structure initialization. Also fixed a typo (TYPE_NAME
6103 was being used on a FIELD_DECL instead of DECL_NAME).
6104 * c-typeck.c (initializer_constant_valid_p): Pass missing
6105 ENDTYPE argument on recursive call.
6106 (set_init_field): New function, needed by ch-convert.c change above.
6108 * ch-decl.c (layout_chill_variants): Added a FIXME next to an
6109 almost certain typo.
6111 * ch-expr.c (build_chill_arrow_expr): Call `build1' and set
6112 TREE_CONSTANT for static references.
6113 * ch-except.c (chill_start_on): Change calls to
6114 `build_unary_op' (which is C-specific) to `build_chill_arrow_expr'
6115 which has CHILL semantics.
6116 * ch-convert.c (convert): Ditto (albeit in some disabled code).
6118 Sat Jan 1 21:26:43 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6120 * ch-satisfy.c (safe_satisfy_decl): Reorder conditional test of
6121 TREE_CODE of DECL in case it's altered by actions in the switch.
6123 * ch-satisfy.c (satisfy): Undo abort added earlier on 1 Jan. CVS log
6124 mentions where to find code that triggers this case.
6126 * ch-actions.c (adjust_parm_or_field): Handle CONSTRUCTORS here as
6129 * ch-convert.c (digest_structure_tuple): Push to permanent_obstack if
6130 we're dealing with a CONSTRUCTOR that is TREE_PERMANENT.
6131 (digest_constructor): Ditto.
6133 Sat Jan 1 10:29:19 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6135 * ch-parse.y (handleraction,resultaction,assignaction,call): Modified
6136 so that CONSTRUCTORS are properly handled before being used.
6138 * ch-convert.c (chill_start_init): New function. All callers to
6139 `start_init' changed to call this function instead.
6140 (digest_struct_tuple): Defend against initialization machinery
6141 mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
6142 IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
6143 needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
6144 can be refered to throughout the compilation unit. Also remove an
6145 extraneous call to `process_init_element' erroneously added to the
6146 variant record sub-loop.
6147 (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
6148 CONSTRUCTORS of SET_TYPE.
6149 * ch-parse.y (build_chill_constructor): Refix typo. Also set
6150 TREE_STATIC if at top level.
6152 * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
6153 TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
6154 should have been called.
6156 * ch-convert.c (digest_struct_tuple): Restore code which tracks
6157 field initializations so that the compiler can deduce what variant
6158 initializations to assume.
6160 * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
6161 when we push into a scope that has a DECL with a CONSTRUCTOR as its
6164 * ch-parse.y (build_chill_constructor): Change the name of the
6165 parameter to something more meaningful. Fix typo. Also, handle case
6166 where element is an untyped CONSTRUCTOR.
6168 * ch-except.c (finish_handler_array): Set TREE_CONSTANT on
6169 constant ADDR_EXPRs.
6170 (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT
6171 on JBUF_REF (instead of calling `build1' which does not).
6173 * ch-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
6175 * ch-typeck.c (chill_expand_tuple): Deleted.
6176 * ch-parse.y (primval rule): Don't call `chill_expand_tuple';
6177 instead, use initialization machinery for CONSTRUCTORS that
6179 * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
6180 that are created here.
6181 * ch-satisfy (satisfy): Abort in case we would have called
6182 chill_expand_tuple. FIXME: some other code is needed here,
6183 but I don't know what yet.
6185 * ch-parse.y (build_chill_constructor): New function to
6186 propagate TREE_CONSTANT bits to CONSTRUCTORS.
6187 (untyped_expr rule): Use it.
6188 (primval rule): Use it.
6190 * ch-decl.c (do_decl): Call `finish_init'.
6191 * ch-convert.c (convert): If we spontaneously create a CONSTRUCTOR in
6192 this function, make sure the initialization machinery is set up.
6194 * ch-convert.c (digest_structure_tuple, digest_constructor): Add
6197 Fri Dec 31 11:31:01 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6199 * ch-grant.c (chill_finish_module_code): Mark ADDR_EXPR built by hand
6200 as being TREE_CONSTANT. Otherwise it gets bounded by the initializer
6203 * ch-decl.c (do_decl): Change in CONSTRUCTOR handling due to...
6204 * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
6205 rewritten to work with GCC's initialization code. The basic change
6206 was to keep the initializers in sync with the initialization
6207 machinery that `process_init_element' imposes. Both of these
6208 functions now return `void'.
6209 * ch-convert.c (convert): Changed calls to `digest_...' functions.
6211 FIXME: the code handling UNION_TYPE (and variant records) has not
6214 Fri Dec 31 15:32:56 1993 Bill Cox (bill@rtl.cygnus.com)
6216 * ch-lex.l (convert_number): Output the converted number if
6218 * ch-parse.y (signaldef): Set ignore_exprs correctly for a
6221 Fri Dec 31 13:17:48 1993 Bill Cox (bill@cygnus.com)
6223 * ch-parse.y: Cleanup handling of RETURN actions, to distinguish
6224 a RETURN without a value (which cannot have an exception
6225 handler) from a RETURN with a value (which can). Eliminate
6226 some shift/reduce and reduce/reduce conflicts.
6228 Thu Dec 30 17:42:32 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6230 * ch-inout.c (build_chill_writetext): Deal with 2 cases where
6231 types returned from `type_for_size' are not expected. FIXME.
6232 * ch-decl.c (init_decl_processing): Mark `char_type_node' unsigned.
6233 This is required when range checking is enabled.
6235 Thu Dec 30 14:28:25 1993 Bill Cox (bill@rtl.cygnus.com)
6237 DELAY CASE works now.
6238 * ch-decl.c (init_decl_processing): Move rest of tasking-related

6249 correct its functioning.
6250 (build_delay_case_end): Correct the code.

6258 failed full regression testing.
6259 * ch-lex.l (name_type_signal): Add debug output.
6260 * ch-parse.y (structured_variable): Add a debug variable.
6262 Wed Dec 29 02:05:51 1993 Bill Cox (bill@rtl.cygnus.com)
6264 * ch-decl.c (get_next_decl): Revert change which failed full
6267 Tue Dec 28 18:20:14 1993 Bill Cox (bill@rtl.cygnus.com)
6269 DELAY actions work now.
6270 * ch-decl.c: Correct spelling in comments.
6271 (get_next_decl): NULL out the decl's TREE_CHAIN before returning
6272 it, to prevent accidental access to the remembered_decls.

6274 * ch-expr.c (build_chill_indirect_ref): Prevent a syntax error from
6275 becoming a seg fault.
6276 * ch-grant.c: Correct a comment.

6279 into rough draft of actual code.
6280 (delayaction): Don't make a new scope here, use get_unique_identifier
6282 (locdec): process event decls here, too.
6283 (mode): Add code to forbid READonly EVENT and BUFFER decls. Delete
6284 code which required EVENTs and BUFFERs to be declared at global scope.
6285 (simple_name_string): Add an EVENTNAME.
6286 * ch-satisfy.c (safe_satisfy_decl): Prevent a syntax error from
6287 becoming a seg fault.
6288 * ch-tasking.c (tasking_setup): Add the event queue's max. length
6289 as the 'entry_point' parameter in the list.

6291 calling runtime routine until we know whether we have a signal
6292 or a buffer to wait for.
6293 (build_delay_case_start, build_delay_case_end,
6294 build_delay_case_label, build_delay_action,
6295 process_event_decls): Added functions.

6301 * gcc.c (CHILL SPECS): Delete references to -M -MM -MD -MMD
6302 options. Delete C-specific defines. Disable piping from
6303 pre-processor to cc1chill (even if -pipe is specified), since cc1chill
6304 rewinds its input for its second pass. Piping still works
6305 from cc1chill to as.
6307 Thu Dec 23 12:31:55 1993 Bill Cox (bill@rtl.cygnus.com)
6309 * ch-tasking.c (decl_tasking_code_variable): Assure that the

6313 Other changes to variable names to increase 'self-documentation'
6314 the only kind GNU CHILL will get, for a while..
6316 Wed Dec 22 10:46:31 1993 Bill Cox (bill@rtl.cygnus.com)
6318 * ch-decl.c (do_seize): Delete - it's unused. Fix comments.
6319 * ch-loop.c (build_chill_iterator): Convert BY expression

6321 for numbered SET expression as start or end expression.
6322 * ch-tree.h: Prototypes for future DELAY functions.
6323 * ch-typeck.c: Standard indentation.
6325 Tue Dec 21 15:30:57 1993 Per Bothner (bothner@kalessin.cygnus.com)

6345 distinguish a string from a char array, and to distinguish a
6346 bitstring from regulat (power)set. (Needed for Chill.)
6347 * dbxout.c (dbxout_type): Only check for baseclasses in
6348 type.binfo is a vector. (It is used in Chill for tagged unions.)

6370 * ch-tree.h: Fix prototypes.
6371 * ch-typeck.c (smash_dummy_type): Handle all four kinds of LANG_TYPE

6389 (non-seize) declarations are proclaim_decl'd *before* we
6390 handle the ALIAS_DECLs for seizes. The advantage is
6391 that we can now test for (an approximation) to the
6392 'seizeable' concept, thus avoiding duplicate definitions
6393 when a module has both GRANTs and SEIZE ALL.
6395 * ch-expr.c (build_chill_arrow_expr): No longer re-write
6396 addr-of-conversion to pointer-conversion-of-addr.
6397 * ch-expr.c (build_chill_addr_expr): Re-write to just use

6406 * ch-expr.c (finish_chill_binary_op): Use CH_ROOT_RESULTING_MODE
6407 macro (which works on expressions), rather than CH_RESULTING_MODE
6408 (which works on modes, and isn't quite correct).
6409 * ch-tree.h (CH_IS_BOUND_REFERENCE_MODE): New macro.

6413 dynamic-length array (and string) types (e.g. slices).
6414 * ch-typeck.c (chill_root_mode): If the mode has a Novelty,
6415 just return it as is. (This is still not 100% correct for
6416 NEWMODE of RANGEs, but is close enough.)

6535 of set elements of similar set modes.
6537 * ch-parse.y (caseaction): Call language-independent

7175 This matches C, and allows dbxout to emit proper user-level names.
7176 (It would be cleaner to fix dbxout to use DECL_NAME ...)
7177 * ch-decl.c (outer_decls): New global list of the decls granted
7178 into the outer scope.
7179 (pop_module): Change code that grants into outer scope accordingly.

7194 * ch-tree.h: Restore old version.
7195 * ch-expr.c (finish_chill_binary_op): Convert TRUNC_DIV_EXPR
7196 to RDIV_EXPR if an operand is floating. (This functionality

7200 not error_mark_node.
7201 * ch-actions.c (chill_expand_assignment): Allow such borderline
7202 constructs as: LHS OR:= [X].
7203 * ch-convert.c (convert): Hande CASE_EXPR (and COND_EXPR)
7204 with unknown (NULL_EXPR) type, not just CONSTRUCTORS.
7205 * ch-decl.c (do_decl): Remove CONSTRUCTOR kludge.
7206 * ch-typeck.c (chill_compatible): Allow expr to have NULL mode
7207 if it's a CASE_EXPR or COND_EXPR (and not just CONSTRUCTOR).

7221 commented-out code as example for assignment of module address to its
7224 Sun Oct 17 15:16:54 1993 Bill Cox (bill@cygnus.com)
7226 * ch-convert.c: Move semicolon to separate line - easier to see.
7227 * ch-decl.c (do_decl): Handle untyped_expr initializers by
7228 simply using the variable's declared type - no compatibility
7229 check can be made if the expression has no type.
7230 * ch-expr.c (expand_packed_set): Fix endless loop - increment
7232 (fold_set_expr): Fix two other endless loops by passing
7233 correct parameters to unpack_set_constructor.
7234 * varasm.c: Standardize 'for' loop.

7278 Thu Oct 14 13:08:07 1993 Per Bothner (bothner@kalessin.cygnus.com)
7280 Changes to better support 1984 version of Chill, which doesn't
7281 really distinguish BOOL and BITS(1) or CHAR and CHARS(1).
7282 * ch-lang.c, toplev.c, ch-tree.h (flag_old_strings): New flag.
7283 * ch-typeck.c (chill_similar): Support flag_old_strings.

7290 Allows cascaded conversions: CHAR -> CHARS(1) -> varying CHARS.
7291 * ch-decl.c (string_type_node, const_string_type_node,
7292 int_array_type_node), ch-tree.h: Removed.

7366 for example, as the module-level code's name.
7367 * ch-loop.c (build_temporary_variable, begin_for_range,
7368 init_loop_counter): Add parameter to decl_temp1 call.
7369 * ch-parse.y (quasi_signaldef): Clear quasi_signal flag here,
7370 for easier maintenance.

7375 to make the variable public (visible to linker).
7376 (build_start_process): Add parameter to decl_temp1 call.
7377 (tasking_setup): Comment out band-aid hack which calls
7378 generate_tasking_code_variable. Shouldn't be necessary.

7416 Mon Oct 4 15:43:56 1993 Per Bothner (bothner@kalessin.cygnus.com)
7418 * ch-convert.c (digest_constructor): Convert element to element_type.
7419 * ch-parse.y (end_function): Use DECL_ARGUMENTS to check
7420 for parameterless process.
7422 Fri Oct 1 13:57:30 1993 Per Bothner (bothner@kalessin.cygnus.com)
7424 * ch-typeck.c (chill_location): New function.
7425 Based on lvalue_p, but also handle Chill-specific VARY_ARRAY_REF.
7426 * ch-typeck.c, ch-tree.h (CH_LOCATION_P), ch-convert.c: Use
7427 chill_location instead of lvalue_p.
7430 Fri Oct 1 11:28:42 1993 Bill Cox (bill@cygnus.com)
7432 * ch-convert.c (convert): Back out Michael's changes, unintentionally
7434 * ch-lex.l (handle_use_seizefile_directive): No longer downcase

7445 * ch-tree.c (build_string_type, build_bitstring_type),
7446 ch-convert.c (convert): Use it.
7447 * ch-typeck.c (build_chill_slice): Take length rather than upper
7448 bound. This makes it easier to recognize that A(X UP LENGTH)
7449 really has fixed length. Also, if the argument is string,
7450 mark the slice as a string too. Also, handle varying strings.
7452 * ch-typeck.c (conflate_singleton_strings): New global.
7453 * ch-typeck.c (chill_similar): If conflate_singleton_strings is
7454 set (as it currently is), allow CHARS(1)/BOOLS(1) to be similar
7455 to CHAR/BOOL, as required by the 1984 version of Z.200.
7456 * ch-convert.c (convert_to_char): Convert CHARS(1) to CHAR.
7457 * ch-convert.c ( build_array_type_for_scalar): If input is string,
7459 * ch-convert (maybe_turn_scalar_into_arra), ch-tree.h: Removed.
7460 * ch-convert.c (convert): Convert CHAR to CHARS(1).
7462 This fixes 'X // := Y' and is also a general simplification.
7463 * ch-actions.c (chill_expand_assignment): Convert 'LHS OP := RHS'
7464 to 'LHS := LHS OP RHS' (using stabilize_reference on LHS).
7465 Also, call save_expr on RHS if a multiple assignment.
7466 * ch-parse.y (assignaction): Therefore, no longer need to call
7467 stabilize_reference on RHS.
7468 * ch-typeck.c (build_chill_modify_expr), ch-tree.h: Remove
7469 modifycode parameter. Make it the caller's responsibility to
7470 handle <assigning operator>.

7472 ch-loop.c: Fix calls to build_chill_modify_expr accordingly.
7474 Wed Sep 29 18:02:55 1993 Per Bothner (bothner@kalessin.cygnus.com)
7476 * ch-lang.c (string_index_type_dummy), ch-tree.h: New variable.
7477 * ch-decl.c (integer_minus_one_node), ch-tree.h: New variable.
7479 * ch-parse.y (arrayindex: modename): Remove useless code.
7480 * ch-satisfy.c (satisfy): Don't gag on string_index_type_dummy,
7481 * ch-tree.c (build_string_type): Pass string_index_type_dummy as
7482 the parent type of the index range.
7483 * ch-typeck.c (layout_chill_range_type): Recognize and handle
7484 string_index_type_dummy - specifically allow an empty range.

7488 * ch-convert.c (convert_to_reference): Check for loc-identity
7489 mismatches correctly (and remove one of those chill_compatible
7491 * ch-decl.c (decl_tasking_code_var): New function, called from
7492 push_extern_process and push_extern_signal.
7493 * ch-parse.y (end_function): Delete parameter. Check current_function_decl
7494 whether it's actually a process, and whether it has parameters.
7495 Make Michael's change simplifying the pass 2 test, preventing a seg
7497 (procedure, process): Change calls to end_function, remove
7498 code saving value from build_process_header. Delete redundant chill_
7499 phrases from some function calls.
7500 * ch-tasking.c: Remove some redundant _chill phrases from function
7502 * ch-tree.h: Remove some redundant _chill phrases from function
7503 names. Add the CH_VARYING_ARRAY_TYPE macro, call it from
7504 all relevant places.
7505 * ch-typeck.c: Use the new macro. Cast TREE_CODEs to chill_tree_code.
7507 Wed Sep 29 13:07:43 1993 Per Bothner (bothner@kalessin.cygnus.com)
7509 * ch-convert.c (convert_to_reference): Remove redundancies.
7510 * ch-convert.c (convert): Handle convert_to_reference
7511 with a recursive convert call.
7512 * ch-decl.c (do_decl): Add missing compatibility-checking
7513 of initializer (don't depend on convert).
7515 Tue Sep 28 00:02:25 1993 Per Bothner (bothner@kalessin.cygnus.com)
7517 * ch-tree.h (CH_LOCATION_P): New macro.
7518 * ch-typeck.c (layout_chill_range_type): Fix call to
7519 type_for_size, when figuring out a defaulted parent type.
7520 * ch-expr.c (build_chill_lower, build_chill_sizeof): Check
7521 for TREE_CODE_CLASS != 't' rather than == 'd'.
7522 * ch-expr.c (build_chill_function_call): Use CH_LOCATION_P
7523 to check for location, rather than TYPE_CODE_CLASS == 'd'.
7525 * ch-tree.c (build_string_type): Make 2-pass safe. Also,
7526 change parameter to be length, not index type.
7527 * ch-parse.y (mode2), ch-expr.c (build_concat_expr), ch-lex.l
7528 (build_chill_string): Modify callers of build_string_type accordingly.
7529 * ch-lex.l (check_newline): Don't look for # directive inside a
7531 * ch-grant.c (grant_array_type): Make more robust for char-
7532 and bit-strings (allow non-constant sizes). Change parameters
7533 and return types. (raw_decode_mode): Use grant_array_type
7534 for bitstrings. (otherwise): Fix grant_array_type callers.
7536 Mon Sep 27 16:57:57 1993 Per Bothner (bothner@kalessin.cygnus.com)
7538 Remove changes of Sep 15.
7539 * ch-tree.h (CH_SINGLETON_DOMAIN): Removed.
7540 * ch-typeck.c (chill_similar): Don't allow a singleton
7541 powerset to be similar to its domain.
7542 * ch-convert.c (convert_to_boolean): Don't convert a singleton
7543 SET_TYPE constructor to a Boolean.
7545 * ch-actions.c (chill_expand_assignment): Handle IN_EXPR on
7546 LHS of assignment, which is what we're current (temporarily?) using.
7548 Mon Sep 27 06:01:57 1993 Bill Cox (bill@rtl.cygnus.com)
7550 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
7551 ch-grant.c, ch-inout.c, ch-parse.y, ch-satisfy.c,
7552 ch-tasking.c, ch-tree.c, ch-tree.h, ch-typeck.c:
7553 -Wall cleanup. Add prototypes where missing.
7554 Delete unused variables. Cast uses of tree_codes
7555 to chill_tree_code, which they are.
7557 Sun Sep 26 13:09:57 1993 Bill Cox (bill@rtl.cygnus.com)
7559 * ch-decl.c (do_decl): Save initializer in pass zero
7561 * ch-lex.l: Fix comments, indentation.
7562 * ch-parse.y: Standardize error messages to use
7563 uppercase for CHILL keywords rather than quoting them.
7564 Suggestion from docs department.
7565 * ch-tasking.c: Pervasive changes to get processes to
7567 * ch-tree.h: Delete prototypes for functions whic
7568 I made static inside ch-tasking.c.
7570 Sun Sep 26 02:40:02 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7572 * ch-lex.l (yywrap): Call `check_newline' in case the file
7573 started with a line directive.
7575 Sat Sep 25 13:54:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
7577 * ch-decl.c: Expand pre-amble comment.
7578 * ch-decl.c (struct scope, push_module): Use new field
7579 tail_chain_module to build child-module list in order.
7580 (Just to make compiler debugging a little less confusing.)
7582 * ch-decl.c (struct scope): New field weak_decls.
7583 * ch-decl.c (find_implied_types): New interface. Now pre-pend
7584 new enum types to a given input list. This makes it easier to
7585 avoid duplicates, which should at least be more efficient.
7586 Also, handle FUNCTION_DECL.
7587 * ch-decl.c (bind_saved_names): Removed. Distribute its
7588 functionality over new functions (push_scope_decls, pop_scope_decls,
7589 build_implied_names, bind_sub_modules). The goal (which seems to
7590 have been more-or-less attained) was to fix weak name handling.
7591 * ch-decl.c (poplevel): Use new function pop_scope_decls.
7593 * ch-tasking.c (build_signal_struct, build_tasking_message_type):
7594 Use build_decl directly, rather than grok_chill_fixedfields
7595 (which depends on ignore_exprs and has more overhead).
7596 * ch-tasking.c (build_signal_struct): Construct the type
7598 * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
7599 than build_array_ref (which does C-specific "optimizations").
7600 (Hence move my_build_array_ref up earlier in the file.)
7602 Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7604 * ch-tasking.c: Declare static variable `void_ftype_void'.
7605 (chill_tasking_init): Initialize `void_ftype_void' here.
7606 (build_tasking_struct): Use, don't declare `void_ftype_void'.
7607 (generate_tasking_code_variable): Call `do_decl', not
7608 `decl_temp1' to declare TASKING_CODE_NAME.
7609 (tasking_setup): Drop into 1-pass mode so that all
7610 tasking-related declarations are installed in the global
7611 scope. Use correct CHILL types for initializers (since
7612 ptr_type_node doesn't have the right meaning for CHILL).
7613 Also, call `do_decl' instead of `decl_temp1' for
7615 (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
7616 `chill_finish_compile' in sync between passes.
7618 * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
7619 declarations on pass zero. Keep obstacks in sync, and always
7620 call `finish_decl' for pass zero declarations.
7621 (push_chill_extern_function): Keep obstacks in sync, and always
7622 call `finish_decl' for pass zero declarations.
7623 (build_enumerator): Ditto.

7635 extra pushing and popping of obstacks.
7637 * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
7638 on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
7640 * ch-grant.c (chill_finish_compile): Clear out both
7641 MODULE_INIT_LIST and TASKING_LIST if either contains stuff
7644 * ch-parse.y (rccase_label): Add NAME rules so that pass one
7645 works w/o knowing we're parsing a signal. Simplify SIGNALNAME
7646 rules since we only get SIGNALNAME tokens in pass two.
7647 (sendaction): Ditto.
7648 * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
7649 BUFFERNAME on pass two. The grammar now handles this.

7652 Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
7654 * ch-decl.c (lookup_remembered_names): Removed. It was being
7655 misused in ch-lex.l.
7656 * ch-lex.l (name_type_signal): Revert last change. Basically,
7657 we cannot use the C typedef/variable name trick in CHILL, due
7658 due to the language's 2-pass nature.
7659 * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
7661 * ch-tree.h (lookup_remembered_name): Comment out the prototype.
7663 Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)

7674 * ch-parse.y: Set pass to zero to indicate initial decl processing.
7675 Replace NAME references with SIGNALNAME references.
7676 (startaction): Only check copy number if not ignoring actions.
7677 Always call build_chill_start_process.
7678 (optstartset): Don't lookup the instance name.
7679 * ch-tasking.c (generate_tasking_code_variable): Replace
7680 do_decl call with decl_temp1 call.

7691 * ch-tasking.c (build_chill_receive_case_start): `namedecl'
7692 should be a _DECL, not an IDENTIFIER_NODE.

7715 ALIAS_DECL the name in the most recent use_seize_file directive.
7716 (This requires that use_seize_file directives written to the
7717 grant file be written before the SEIZEs that need it.)
7718 Allow clashing declarations granted into the global scope
7719 (produce a warning), but remember the seizefile case from
7720 (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
7721 The a SEIZE will select the granted decl that matches its
7722 DECL_SEIZEFILE (in other words: grants from the most recent
7723 use_seize_file will be preferred).
7724 * ch-tree.h (DECL_SEIZEFILE), ch-tree.def: New macro.
7725 * ch-tree.h (global_value, IDENTIFIER_GLOBAL_VALUE): Renamed
7726 to outer_value, IDENTIFIER_OUTER_VALUE.

7732 Don't call grant_use_seizefile.
7733 * ch-lex.l (mark_use_seizefile_written): New function.
7734 * ch-grant.c (decode_decl): Write out use_seize_file directive,

7737 module specially, setting IDENTIFIER_OUTER_VALUE.
7738 * ch-decl.c (lookup_name_for_seizing): Check IDENTIFIER_OUTER_VALUE.

10333 * ch-grant.c (chill_finish_module_code): Since module
10334 function is no longer visible,, can't get it using
10335 lookup_name(). Use current_function_decl instead.
10337 * ch-decl.c (build_chill_function_type): Add void_type_node
10338 to end of parameter types list.
10340 * ch-grant.c (chill_start_module_code): Make sure module

10411 (start state 'ccitt'): Deleted, unused. Moved unused, but reserved,
10412 tokens to NORMAL state.
10413 (compiler_directive): Replaced by equal_number. Now the only
10414 recursive call to yylex happens in check_newline at the beginning
10417 Sat Apr 10 09:55:50 1993 Bill Cox (bill@rtl.cygnus.com)
10419 * ch-actions.c (build_chill_case_expr): Added from ch-parse.y.
10420 * ch-lex.l (ENTRY, PERVASIVE, ROW, STEP): Add token recognition to

10429 Sat Apr 10 01:10:51 1993 Per Bothner (bothner@rtl.cygnus.com)
10431 * ch-parse,y (in_pseudo_module): New variable. Try if we're
10432 in a seizefile, but not in a module nested in the seizefile.

10454 out of sequence" (they're both legal and work).
10455 * varasm.c (mak_function_rtl): Remove kludge that may
10456 not be necessary (and loses anyway).

10496 assignment, clean up.
10497 * ch-typeck.c: Add prototype for require_complete_type.

10510 * ch-tree.h (massage_param_node): New prototype.
10511 * ch-decl.c (push_parms): Use new massage_param_node().

10558 Fri Apr 2 21:55:14 1993 Per Bothner (bothner@rtl.cygnus.com)
10560 Major re-write of New module/seize/grant stuff.
10561 Now, a grantfile is a spec module and contains all the
10562 top-level declarations of the granting module, not just
10563 those that are granted. It also contains explicit grant
10564 statements naming those declared names that are granted.
10565 It also has seize statements and use_seize_file directives
10566 to correctly handle transitive dependencies.
10568 * ch-parse.y: Change to allow multiple modules per source file.
10569 Allow spec modules (including quasi definitions) as well as
10571 Allow spec modules inside normal modules; these behave as if
10572 they were outermost. This violates the Blue Book, but is
10573 needed by the new grantfile mechanism. (A grant file is a
10574 spec module that gets included by the use_seize_file directive.)
10575 * ch-parse.y (struct module *current_module, push_module,
10576 pop_module): Support module nesting (for spec modules only).
10578 * ch-tree.h (struct module): New.
10579 * ch-grant.c (granted_decls): New list of declarations
10580 that have been granted into the outermode pseudo-module.
10581 * ch-grant.c (decode_mode): If the decl has a name,
10582 always write the name, not just if the decl has already
10583 been written. Since we write out all decls, we can assume
10584 it will be written later, and depend on the forward
10585 declaration kludges to catch it.
10586 * ch-grant.c (decode_decl): Don't write out _EXTERN.
10587 Instead write out standard (Blue Book) quasi-definitions.
10588 * ch-grant.c (push_granted): New function.
10589 * ch-grant.c (seize_implied_names): New function. Re-write
10590 how set element names are seized when a set type is seized.
10591 * ch-grant.c (chill_seize): Work by seraching the
10592 granted_decls list and copying the declaration.
10593 * ch-grant.c (chill_grant): Write all declarations
10594 declared in this module. Write GRANT statements for
10595 those granted. seize statements for decls seized from
10596 other modules. Write extra syntax to make a complete
10598 * ch-grant.c (grant_use_seizefile): Copy use_seize_file
10599 directives into grant file.
10600 * ch-lex.l (setup_seizefile_read): Call grant_use_seizefile.
10602 * ch-lex.l (struct input_state, current_input_state,
10603 push_input_file, pop_input_file): New (type, variable,
10604 function*2). Used to save and restore state on an input file.
10605 * ch-lex.l: Clean up to handle nested input seizefiles
10606 (needed by new grant/seize mechanism.
10607 * ch-lex.l (skip_to_end_of_directive): New function.
10608 * ch-lex.l (compiler_directive: USE_SEIZE_FILE): Make sure
10609 we skip to the end of the directive *before* we switch
10611 * ch-lex.l (setup_seizefile_read): Prevent reading the
10612 same seizefile twice (otherwise likely with new grant/seize).
10613 * ch-lex.l: Recognize SPEC. Misc cleanups.
10615 * ch-parse.y: Fixed foreward references of types.
10616 Removed the unknown_type_node crock.
10617 * ch-decl.c: Remove all uses of unknown_type_node.
10618 Check for TYPE_SIZE zero instead.
10619 * ch-decl.c (fixup_unknown_type): Make sure new mode
10620 gets copied into old mode. Merge their variant chains.
10621 * c-decl.c (lookup_name_current_level): Make non-static.
10622 * ch-decl.c (lookup_name_current_level): No longer needed.

10625 name following the CALL keyword.
10626 * ch-tree.h (struct lang_identifier): Add implicit_decl,
10627 and make sure order of fields matches c-tree.h.
10629 * ch-actions.c (lang_init, build_allocate_memory_call,
10630 build_allocate_globals_memory_call): Fix names (add initial '_')
10631 and prototypes of _allocate_[global_]memory (2nd param is ref).
10632 Use build_chill_function_call, not build_function_call,
10633 so the reference parameter gets handled.
10634 * ch-actions.c. (lang_init): Make sure boolean_{true,false}_node
10635 have boolean_type_node as their types.
10636 * ch-actions.c (build_chill_lower, build_chill_upper): Fix to
10637 work for arrays with BOOLEAN_TYPE ranges (and simplify some).
10639 * ch-except.c: Make sure an end_label is generated,
10640 and jump to it if there is no exception.
10642 * ch-convert.c (convert_to_reference): Strip off NOP_EXPR casts.
10643 * expr.c (expand_expr): Handle NOP_EXPR as Chill-style casts.
10644 (Need cleaning up and FSF installation!)
10645 * ch-parse.y: If taking the address of a cast, move the
10646 ADDR_EXPR inside the NOP_EXPR.
10648 * ch-typeck.c (my_build_array_ref): Simplified, more suitable
10649 versions of build_array_ref from c-decl.c. (E.g. don't barf
10650 if index type is char or bool.)
10651 * ch-typeck.c (build_chill_array_ref): Use my_build_array-ref.
10653 * ch-typech.c (build_chill_bin_type): New function.
10654 Support BIN(N) range type specification.
10655 * ch-parse.y (mode2), ch-lex.l: Recognize BIN(N).
10657 * ch-tree.h (CH_SIMILAR): Redefine in terms of chill_similar.

10659 that range types are similar to their parent types.
10661 * ch-tree.h: Declare flag_local_loop_counter.
10662 * ch-loop.c: Whether the loop variable is local to the loop
10663 in now controlled by flag_local_loop_counter, instead of

10665 * ch-actions.c (lang_decode_option): Recognize flags
10666 "-f[no-]local-loop-counter".
10667 * toplev.c (lang_options): Add Chill flags -f[no-]local-loop-counter.
10669 * varasm.c (make_function_rtl): Due to problems with forward
10670 references, don't rename nested functions in Chill. (Kudge!)
10672 Sun Mar 28 10:12:45 1993 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10674 * ch-lex.l (push_back, readstring): Fix prototypes.

10696 as-yet-undeclared types. Check for IDENTIFIER_NODE, lookup its
10697 DECL if there, pass TREE_TYPE of decl to build_pointer_type.
10698 (variantfields, varianthack): Clean up.
10699 (variantfield): Check for IDENTIFIER_NODE, lookup its DECL if
10700 there, pass TREE_TYPE of decl to grok_fixedfields.

10735 array and its type get on the permanent obstack.
10736 * ch-grant.c (write_grant_file): Don't write the _INIT=name

10740 * ch-lang.c (finish_chill_enum): Don't allocate a dummy
10741 TYPE_DECL for the enum. I don't think it is needed (?),

10778 * ch-parse.y (structured_variable): Return NULL_TREE is invalid WITH
10779 parameter is seen, don't count it in structured_variable_list. Pre-
10780 vents seg fault when only WITH operand is invalid.
10781 * ch-parse.y (label_spec): Correct assignment within IF expression which
10782 was intended to be equality test. Remove unused variables.
10783 * ch-tree.h: Add prototype. Remove unused EXCP_CODE enumeration, and
10784 prototyping editorial comments.
10785 * ch-typeck.c: Disable generation of code to validate array index for
10786 now. Should be done as a call-back from more generic array_ref code.

10935 build_chill_length: Move VARYING array handling before regular char
10937 * ch-expr.c chill_expand_expr: Disable concatenate code - we need to
10938 the VARYING status of the target to do this correctly. Use powersetlen
10939 for the powerset operations, not a byte length.
10940 * ch-loop.c: Make CREATE_SCOPE #define to enable creation of a new scope
10941 for each CHILL loop, as Z.200 requires. Add powerset and error flags
10942 to loop structure. Evaluate user's powerset expression into a temp,
10943 scan it destructively with __ffsetclrpowerset or __flsetclrpowerset
10944 for powerset loop. Only do loop-end assignments if NOT a powerset
10945 loop, which has much less overhead now.

11167 New functions, to expand SET_TYPE CONSTRUCTORs.
11168 * varasm.c (output_constructor): Use pack_set_constructor
11169 to assemble a SET_TYPE constant from a CONSTRUCTOR.

11172 enumeral, and bitstring constants.
11173 * ch-grant.c: Fixes in seize to avoid duplicates, and emit
11174 things in the correct order.
11175 * c-typeck.c (chill_initializer_constant_valid_p): Kludge
11176 needed to export a static function.
11177 * ch-typeck.c (convert): Avoid needlessly (and lossingly) calling
11178 chill_expand_tuple to convert fix string to varying.
11179 * ch-actions.c (build_chill_binary_op): Promote short
11180 integer operands if needed (otherwise emit routines barf).
11181 * ch-tree.h (SET_WORD_SIZE): New macro.
11182 * ch-parse.y: Fix syntax for RECEIVE CASE.
11183 * ch-parse.y (location): If IDENTIFIER is a CONST_DECL
11184 return its value instead.

11200 chill_integer_type_node. Rewrite _max and _min routines,
11201 redefine the signatures for those runtime routines. Move
11202 empty-set check into runtime.
11203 * ch-expr.c, ch-loop.c, ch-process.c, ch-tree.c, ch-typeck.c: change
11204 most integer_type_node references to chill_integer_type_node.

11209 * ch-parse.y: Add working exception handling support.
11210 * ch-lex.l, ch-parse.y: Prefer standard type terminology
11211 (BOOLS, CHARS) even though non-standard (BITS, CHAR) is ok.
11212 * ch-grant.c: Fix various problems related to granting
11213 types such as bitsets.
11214 * ch-tree.c (build_bitstring_type): Set TYPE_MIN_VALUE
11215 to distinguish bitstrings from powersets (in the same way
11216 we distinguish char strings from char arrays).

11218 * ch-tree.h, ch-actions.c (lang_init), ch-grant.c (decode_mode):
11219 Undo kludge where integer_type_node was hardwired to 16 bits.
11220 Make integer_type_node etc have the same size as in cc1.
11221 New types chill_integer_type_node and chill_unsigned_type_node
11222 that correspond to the Chill source types INT and UINT.
11223 For now, these match the C 'short' types, but that should
11224 become a configuration option later,
11226 Tue Feb 9 11:41:25 1993 Bill Cox (bill@rtl.cygnus.com)
11228 * ch-actions.c (build_chill_unary_op): allow NOT of a set.
11230 Tue Feb 9 08:27:18 1993 Bill Cox (bill@rtl.cygnus.com)
11232 * ch-actions.c (build_chill_function_call): add test for
11233 too many/few actual parameters (and avoid seg fault).

11235 * ch-loop.c (begin_chill_loop, end_chill_loop): remove
11236 emit_nop() calls - they now (since exceptions) cause seg faults.

11239 * ch-tree.h: remove prototypes added to c-tree.h.

11244 Sun Feb 7 18:20:49 1993 Bill Cox (bill@rtl.cygnus.com)
11246 * ch-tree.def: add a new tree type - just for varying array
11247 references. We were using ARRAY_REF, but the underlying C
11248 code also generates that one.
11249 * ch-convert.c, ch-expr.c, ch-typeck.c: use the new tree type.
11251 Sun Feb 7 17:33:17 1993 Bill Cox (bill@rtl.cygnus.com)

11315 smaller actions directly (maybe_array_ref() used to call them).
11316 * ch-tree.h: add build_chill_function_call, build_chill_slice
11317 * ch-typeck.c: add build_chill_slice()

11478 * dwarfout.c (output_type): Add hack that matches the one in the
11479 chill front end to distinquish between true string types and
11480 arrays of char, since it uses ARRAY_TYPE for both, rather than
11481 trying to use the existing support for STRING_TYPE.

11543 * chill.gperf, ch-hash.h: add Wilfried's tokens
11544 * ch-lex.l: fold in Wilfried's changes. Some tokens

11591 for BIT_FIELD_REF with non-constant bit position (which is
11592 not yet handled by expand_expr).

11608 * ch-parse.y: tiny cleanup.
11610 Wed Jan 6 13:25:33 1993 Bill Cox (bill@cygnus.com)
11612 * modules: use gdb rather than naked-gdb, to get opcodes
11613 in chill definition.
11615 Wed Jan 6 09:48:35 1993 Bill Cox (bill@cygnus.com)
11617 * ch-typeck.c: add code to handle references to elements of VARYING
11618 arrays. Simplify chill_give_type_to_expr. Add rough draft of run-
11619 time index checking for VARYING arrays (under #if 0).
11620 * ch-actions.c: new function cond_type_range_exception & calls.
11621 New function cond_range_exception, for more general range-checking.

11623 for the special varying field names.
11624 * ch-tree.h: define macros for varying field names.
11625 * ch-expr.c: use macros for varying struct names. Simplify
11626 chill_expand_array_assignment.

11640 Move shared code into ...
11641 * ch-decl.c (start_chill_function): ... here.
11642 * ch-decl.c (start_chill_function): Add missing call to
11643 expand_start_bindings.

11655 Mon Jan 4 17:57:48 1993 Per Bothner (bothner@cygnus.com)
11657 * ch-grant.c, ch-parse.y: Remove all code for explicitly
11658 calling initializer functions. This is not needed, since we
11659 use the same mechanism used for C++ static constructors.
11660 * ch-grant.c (chill_start_module_code): Make sure the
11661 init_name starts with the magic string also used for C++
11662 initializers. Also, don't embed the file name in the name,
11663 just use the module name.
11664 * ch-grant.c (chill_finish_module_code): Now that the
11665 initializer name follows the standard 'collect' convention,
11666 don't need to call assembler_constructor_alias, but can
11667 use the standard assemble_constructor instead.
11668 * varasm.c (assemble_constructor_alias): Remove no-longer-
11670 * ch-parse.y: Move code that is common to the beginning of
11671 all functions to a new macro INIT_ACTION.
11672 Make sure INIT_ACTION is also done for callaction, fixing a bug.
11673 * ch-parse.y (INIT_ACTION): Do chill_start_module_code()
11674 before emit_line_note(), not after.
11676 Mon Jan 4 11:43:12 1993 Bill Cox (bill@cygnus.com)
11678 * ch-parse.y: restore requirement for :upper-bound in array decl.
11679 * ch-actions.c: enhance upper, lower, length functions for VARYING.
11681 Mon Jan 4 09:28:44 1993 Bill Cox (bill@cygnus.com)

11696 Sun Jan 3 11:36:39 1993 Bill Cox (bill@cygnus.com)
11698 * ch-parse.y: define IGNORED_DIRECTIVE
11699 * ch-typeck.c: subtract array's lower domain value, even if
11700 index expression is constant.

11704 * ch-lex.l (convert_float): Fix misspelling in error message.
11706 Sat Jan 2 16:02:16 1993 Per Bothner (bothner@rtl.cygnus.com)
11708 * Makefile.in: Took out chill-runtime support.
11709 Chill run times are now in ../chillrt, not ./chillrt.p
11711 Sat Jan 2 15:04:13 1993 Bill Cox (bill@cygnus.com)
11713 * ch-hash.h, chill.gperf: cleanup. fewer keywords seen by ch-parse.y.
11715 Sat Jan 2 13:27:49 1993 Per Bothner (bothner@rtl.cygnus.com)
11717 * ch-lex.l (check_newline): Use the orginal versions (derived
11718 from the C code, not the simplified, special-case version).
11719 Also, fix that version of check_newline to not call yylex()
11721 * ch-lex.l (yy_input): Call check_newline to handle
11722 newlines and check for # directives.
11723 * ch-lex.l (syntax): Don't recognize #-directives; these
11724 are now handled by check_newline.
11725 * ch-actions.c (lang_init): Call the modified version of
11726 check_newline(). Do this at the *after* we've initialized
11727 standard types, so this can be done while lineno is still 0.
11729 Sat Jan 2 10:57:20 1993 Bill Cox (bill@cygnus.com)
11731 * ch-hash.h, chill.gperf: add remaining reserved words.
11733 Sat Jan 2 09:59:55 1993 Bill Cox (bill@cygnus.com)
11735 * ch-tree.h, ch-parse.y, ch-lex.l: add remaining reserved words,
11736 names for exceptions
11738 Fri Jan 1 12:30:31 1993 Fred Fish (fnf@cygnus.com)
11740 * ch-tree.h (JOINER): Define joiner character the same way
11742 * ch-grant.c (chill_start_module_code): Use JOINER character
11743 to implement name mangling for the initializer function name.
11744 Algorithm is designed to be simple, distinct from C++ mangled
11745 symbols, and easy to convert to demangled form.
11747 Thu Dec 31 10:30:51 1992 Bill Cox (bill@rtl.cygnus.com)
11749 * ch-expr.c: make array assignments work with indirect refs.
11750 * ch-actions.c: prepare for array parameter handling.
11751 * ch-loop.c, ch-parse.y, ch-tree.def, ch-typeck.c: clean up.
11753 Thu Dec 31 15:29:20 1992 Per Bothner (bothner@rtl.cygnus.com)
11755 * ch-lex.l (yy_input): Re-write to return more than one
11756 character at a time (execpt when reading seize-files).
11757 Don't increment lineno until we start reading the next line.
11758 This fixes some off-by-one errors in lineno.
11760 Wed Dec 30 16:15:23 1992 Per Bothner (bothner@rtl.cygnus.com)
11762 * ch-convert.c: Assume use of new common.c.
11763 * ch-convert.c (convert_to_reference, convert_from_reference):
11764 New routines, to handle loc-identity declared variables and
11765 LOC parameters (both of which are implemented as references).
11766 * ch-lang.c (convert_to_boolean, convert_to_char): Move to
11767 ch-convert.c, where they would seem to belong.
11768 * ch-convert.c (convert): New function, since we no longer
11769 link in c-convert.c.
11770 * ch-expr.c (chill_expand_assignment): Handle by calling
11771 convert() instead of chill_comptypes().
11772 Also handle the LHS being a reference.
11773 * ch-parse.y: Add a procedure call as an action.
11774 * ch-parse.y (locdec, optlocinit): Move handling of
11775 loc-identity declarations from optlocinit to locdec
11776 - and add working semantics for it.
11777 * ch-parse.y (seizestatement, visibilty_stmt): Simplify.
11778 * ch-parse.y (grantstatement etc): Don't bother making list.
11779 * ch-lex.l: #include <sys/types.h> before <sys/stat.h>.
11781 Wed Dec 30 16:06:55 1992 Bill Cox (bill@rtl.cygnus.com)
11783 * ch-parse.y, ch-expr.c: add support for declaring & assigning
11785 * ch-typeck.c: allow VARYING structures in assign_type_to_expr.
11787 Tue Dec 29 15:28:48 1992 Bill Cox (bill@cygnus.com)
11789 * ch-actions.c: implement expressions of arrays of char,
11790 ( concatenation, relationals ), correct type of code parameters
11791 * ch-expr.c: correct type of code parameters
11793 Tue Dec 29 11:16:19 1992 Bill Cox (bill@cygnus.com)
11795 * ch-decl.c: cleanup.
11796 * ch-parse.y: put emit_line_note() calls in lotsa places,
11797 per Fred's request; be sure that statements get counted also.
11798 * ch-lex.l: standardize function headers.
11800 Tue Dec 29 10:41:56 1992 Fred Fish (fnf@cygnus.com)
11802 * ch-decl.c (start_chill_function): Always return 1, rather
11803 than a random value.
11804 * ch-lex.l (check_newline): Add a version for chill that
11805 just snarfs the right value for main_input_filename out of
11806 the first line of the input file, without disturbing the
11807 lexer state or requiring it's assistance.
11808 * ch-actions.c (lang_init): Call check_newline, like the
11809 other language frontends, to get main_input_filename set
11810 from first line of input file.
11812 Mon Dec 28 18:49:01 1992 Bill Cox (bill@cygnus.com)
11814 * ch-parse.y: clean up conflicts. The remaining one is
11817 Mon Dec 28 17:28:40 1992 Bill Cox (bill@cygnus.com)
11819 * ch-parse.y, ch-lex.l, ch-actions.c: add stubs for I/O,
11820 clean up some parser conflicts.
11822 Mon Dec 28 15:00:20 1992 Bill Cox (bill@cygnus.com)
11824 * ch-parse.y, ch-lex.l: add keywords and parsing for most of
11827 Sat Dec 26 20:48:23 1992 Fred Fish (fnf@cygnus.com)
11829 * chillrt/chillrt0.c: Oops, SVR4 doesn't need leading '_'
11830 on build_exceptions.
11832 Sat Dec 26 11:00:36 1992 Fred Fish (fnf@cygnus.com)
11834 * ch-grant.c (chill_finish_module_code): Call
11835 assemble_constructor_alias rather than assemble_constructor.
11836 * varasm.c (assemble_constructor_alias): New function,
11837 like assemble_constructor, but also handles the case where
11838 ASM_OUTPUT_CONSTRUCTOR is not defined and GNU ld is not
11839 being used. Emits a symbol table alias name with the correct
11840 prefix for collect to find and add to the __CTOR_LIST__.
11841 * chillrt/chillrt0.c: Build on previous hack that gets
11842 _build_exceptions into the __CTOR_LIST__, to make it work
11843 for both the non GNU-ld case and for the SVR4 case.
11845 Tue Dec 22 18:24:55 1992 Bill Cox (bill@cygnus.com)
11847 * ch-loop.c: clean up location enumeration - one more

11861 ch-loop.c: rough draft of location enumeration
11862 ch-lex.l, ch-expr.c, ch-decl.c: minor cleanup
11863 ch-actions.c: finish making pred() and succ() work.
11865 Mon Dec 21 10:04:35 1992 Bill Cox (bill@cygnus.com)
11867 * ch-actions.c: allow pred(char) and succ(char).
11869 Sun Dec 20 16:04:28 1992 Bill Cox (bill@cygnus.com)
11871 * ch-expr.c, ch-actions.c, ch-parse.y, ch-loop.c,
11872 c-expr.c: make DO WITH work.
11874 Sun Dec 20 12:22:53 1992 Bill Cox (bill@cygnus.com)
11876 * ch-loop.c, ch-actions.c, ch-typeck.c: powerset loops
11879 Sat Dec 19 14:20:23 1992 Per Bothner (bothner@cygnus.com)
11881 * c-typeck.c (process_init_constructor): Add warning if
11882 there is a duplicate default initializer element.
11883 * ch-typeck.c (chill_give_type_to_expr): New function,
11884 to handle coercion of an expression to context-given type,
11885 Takes care of untyped tuples, and case expressions.
11886 * ch-decl.c (do_decls), ch-typeck.c (chill_expand_return,
11887 chill_expand_result), ch-parse.y <assignaction>:
11888 Use chill_give_type_to_expr().
11889 * ch-typeck.c (chill_handle_case_label): New parameter list,
11890 to handle the (new) conventions for <case_label>, including
11891 default elements and ranges.
11892 * ch-parse.y <expanded_case_label>, ch-typeck.c
11893 (expand_case_expr): Use new version of chill_handle_case_label.
11894 * ch-decl.c (push_syndecls): Change parameters: Instead of
11895 TREE_LIST representing a compete <synonym definition statement>,
11896 just pass the parts of a single <synonym definition> as 3
11897 different parameters. Also, use chill_give_type_to_expr(),
11898 to handle untyped tuples in the RHS.
11899 * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct
11900 a tree - just call push_syndecls() on each <synonum_definition>
11902 * ch-parse.y (exprlist_get_single): Remove; no longer needed.
11903 * ch-parse.y: Handle <tuple> without mode name diferently from
11904 <tuple> with mode name. The latter is a <primval> that can be
11905 in most contexts, but if the <mode name> is missing, the <tuple>
11906 is only allowed in certain contexts. Use the new non-terminal
11907 <untyped_expr> to indicate those contexts where untyped tuples
11908 (and case expressions) are valid because the expression gets a
11909 type from its context (such as the RHS of an assignment).
11910 Use chill_give_type_to_expr in those contexts.
11912 Sat Dec 19 14:01:26 1992 Bill Cox (bill@cygnus.com)
11914 * ch-actions.c, ch-loop.c, Makefile.in: looping stuff.
11916 Sat Dec 19 10:16:20 1992 Bill Cox (bill@cygnus.com)
11918 * ch-parse.y: clean up warning messages from byacc. bison
11919 still complains thrice.

11923 * ch-actions.c (maybe_chill_comptypes): Delete unused
11925 (chill_comptypes): Add new parameter ERRSTR. All callers
11927 (build_chill_binary_op): Fix indentation to match GNU coding
11930 Fri Dec 18 08:18:13 1992 Bill Cox (bill@rtl.cygnus.com)
11932 * ch-parse.y, ch-expr.c, ch-actions.c, expr.c: major

11942 a default initializer element.
11943 * ch-parse.y: Implement default elements for tuples
11944 (as in '(else):' and '(*):' ).
11946 * ch-parse.y: Previous change to dis-ambiguate case-labels
11947 seems to have allowed getting rid of all of the expr_or_list hair.
11948 * ch-decl.c (do_decls): Undo Tiemann's change to "Handle
11949 initialization of multiple variables by a tuple" - the
11952 Wed Dec 16 11:17:53 1992 Bill Cox (bill@cygnus.com)
11954 * ch-parse.y: complete re-write of DO statement handling.
11955 now operational, except WITH is stubbed out. Improved
11956 syntax error message.
11957 * ch-actions.c: DO support: high_domain_value(), low_domain_value ().
11958 * ch-expr.c: fixes to IN_EXPR handling.
11960 Tue Dec 15 17:15:13 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11962 * ch-grant.c: Add casts to alloca return to avoid compiler warning.
11963 * ch-lex.c: Likewise.
11965 * Makefile.in (ch-lex.c): Delete incorrect free declaration added
11966 by flex to avoid compiler error.
11968 Tue Dec 15 08:41:08 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11970 * ch-decl.c (do_decls): Handle initialization of multiple
11971 variables by a tuple.
11973 * ch-decl.c (do_decls,start_chill_function): Make DECL public
11974 if we're doing a GRANT ALL at top level.
11976 * ch-lang.c (build_range_type): Deal with typecast to CHAR in
11979 * c-typeck.c (digest_init): SET_TYPE is not a scalar type.
11980 BOOLEAN_TYPE and CHAR_TYPE are scalar types.
11982 Mon Dec 14 14:58:32 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11984 * ch-lex.l (get_chill_{linenumber,filename}): New functions.
11985 (convert_number): Use LONG_TYPE_NODE instead of INTEGER_TYPE_NODE.
11987 Mon Dec 14 13:36:44 1992 Bill Cox (bill@cygnus.com)
11989 * expr.c: install and test newer Pascal IN_EXPR code,
11990 but don't activate it - it's very verbose.
11992 Mon Dec 14 00:22:49 1992 Fred Fish (fnf@cygnus.com)
11994 * Makefile.in (LANGUAGES): Add chill.
11995 * Makefile.in (CHILL_INSTALL_NAME, CHILL_CROSS_NAME):
11996 New macros for chill native and cross installation names.
11997 * Makefile.in (COMPILERS): Add cc1chill.

12001 sublibchill.a, ch-parse.o, ch-parse.c ch-*.o, install-libchill,
12002 install-librmt): New targets.
12003 * Makefile.in (install-native): Add install-libchill,

12008 * ch-actions.c, ch-expr.c: Fix the pop-count in library calls.
12010 Sun Dec 13 14:07:32 1992 Bill Cox (bill@cygnus.com)
12012 * ch-actions.c: fix unary operations, modulus ops,
12013 (discovered after extending regression tests).

12017 * resync with Michael and Wilfried
12019 Sun Dec 13 09:11:25 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
12021 * ch-parse.y (output_constant): Fixed some whitespace
12023 * ch-tree.h: Add declarations for new chill functions that
12024 have been implemented but not (yet) declared.
12026 Sat Dec 12 00:17:23 1992 Per Bothner (bothner@cygnus.com)
12028 * c-typeck.c (process_init_constructor): Warn about duplicate
12029 labels for labelled initializer elements.
12030 * ch-lex.l (various operator tokens, such as "+"): Don't
12031 set yylval.code to a TREE_CODE; this is better done in parser.
12032 * ch-parse.y: Some work with case labels and tuples.
12033 Get literal range as tuple (and case) labels working.
12034 Fix some problems introduced by recent grammar overhaul.
12036 Fri Dec 11 13:28:48 1992 Bill Cox (bill@cygnus.com)
12038 * ch-actions.c, ch-parse.y ch-tree.h ch-expr.c, ch-typeck.c:
12039 got long, real expressions working. We can also call a func-
12040 tion and use its return value.
12042 Thu Dec 10 14:45:17 1992 Per Bothner (bothner@cygnus.com)
12044 * ch-parse.y: Major change to remove or at least identify
12045 parser ambiguities. One result: We now allow actions that
12046 start with '(', as required by teh Blue Book. This does break
12047 some things; look for FIXME for things that need work.
12048 * ch-typeck.c (chill_expand_case_expr): We need an extra
12049 level of looping to (in the future) support <case label
12050 specification>s with more than one <case label list>.

12074 on arrays of BOOLs.
12076 Mon Dec 7 08:55:20 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
12078 * ch-actions.c (lang_init): Set LINENO to 1 at beginning to
12079 indicate we are done with initialization.
12081 * ch-decl.c (do_decls): Set TREE_PUBLIC if we are doing a
12083 (start_chill_function): Ditto.
12085 * ch-lex.c (convert_bitstring): Set TREE_CONSTANT.

12102 * tree.def: Move CARD_EXPR and SET_LE_EXPR back down with the other
12103 Pascal-required ones, since C++ no longer needs them. When
12104 Chill's public, a comment can be added to the effect that
12105 SET_LE_EXPR is also used by Chill.

12147 * ch-decl.c (fixup_unknown_type): New function.
12148 (push_newmode,push_synmode): Call `fixup_unknown_type' when we
12149 see a declaration that uses `unknown_type_node'. FIXME.
12151 * ch-grant.c (decode_constant): New function.
12152 (decode_decl): Call `decode_constant' for CONST_DECLs.
12154 * ch-lex.l (char action): Use ridpointers instead of
12155 lookup_name to get "char"'s declaration.
12157 * ch-parse.y: Call `build_lang_decl' instead of `build_decl'
12158 when we need to build a TYPE_DECL.
12160 Tue Dec 2 09:44:05 1992 Bill Cox (bill@cygnus.com)
12162 * ch-typeck.c: clean up a gcc warning with a forward
12163 declaration of build_string_type.
12165 Tue Dec 1 16:51:05 1992 Bill Cox (bill@cygnus.com)
12167 * ch-actions.c: completely remove those builtin calls
12168 that are duplicated in c-decl.c
12170 Tue Dec 1 16:38:51 1992 Fred Fish (fnf@cygnus.com)
12172 * ch-actions.c (lang_init): Ifdef out initializations for
12173 __builtin_abs and __builtin_fabs, since they are duplicates of
12174 initializations in c-decl.c, and trigger spurious warnings.
12176 Tue Dec 1 16:35:18 1992 Bill Cox (bill@cygnus.com)
12178 * ch-parse.y: make size() work with a typename argument.

12205 Mon Nov 30 17:35:33 1992 Fred Fish (fnf@cygnus.com)
12207 * chillsh: New script frontend (ala g++), installed as "chill".
12208 Can't be called "chill.sh" because make tries to cat it into the
12209 "chill" directory. Can't be called just "chill" cause that's
12210 already there as a directory.
12211 * Makefile.in: Add rules to install chillsh as "chill".
12212 * chill/libchill.c: Temporarily ifdef out stuff that wants
12213 to conflict with i486/SVR4 runtime or wants to pull in librmt.a,
12214 which itself causes linkage to fail.
12216 Mon Nov 30 16:28:19 1992 Bill Cox (bill@cygnus.com)
12218 * ch-lex.l: added keywords for TRUNC, ROUND, FLOAT, LFLOAT
12219 conversion routines.
12220 * ch-parse.y: added %tokens for TRUNC, ROUND, FLOAT, LFLOAT.
12221 Added production for SIZE(expr).
12222 * ch-actions.c: Add semantic routine chill_sizeof ().

12226 * ch-lex.l, ch-parse.y: Translate token PFEIL into English ARROW.
12227 * ch-parse.y (op6): Remove handling of string repetition operator,
12228 until we can figure out a way to parse it correctly.
12229 * ch-parse.y (optmodename): New non-terminal.
12230 * ch-parse.y (tuple): Merge the two variants using optmodename.
12231 * ch-parse.y (location): Add semantic actions for
12232 dereferencing operator ->.

12236 * ch-actions.c: removed compile warning, better code for abs.
12238 * ch-parse.y: add productions for builtin functions succ, pred,
12239 abs, and size. Add %tokens also. Sort %tokens alphabetically.
12241 * ch-lex.l: add parsing for builtin function names, such as abs,
12242 pred, succ, etc. Put flex -a option into Makefile.in, so we can
12243 clean up the lexer soon.
12245 Tue Nov 24 14:18:48 1992 Per Bothner (bothner@rtl.cygnus.com)
12247 * ch-typeck.c (chill_handle_case_label, chill_handle_case_default):
12248 New functions, for code common to CASE actions and expressions.
12249 * chill.y: Replace some code by calls to chill_handle_case_label
12250 and chill_handle_case_default.
12251 * ch-typeck.c (chill_expand_case_expr): Add semantics.
12253 * tree.c: Change doing_chill_thang from extern to common.
12255 Mon Nov 23 18:34:22 1992 Per Bothner (bothner@rtl.cygnus.com)
12257 * ch-tree.def: New CASE_EXPR type, for case expressions.
12258 * ch-expr.c (chill_expand_expr): Hook for CASE_EXPR.
12259 * ch-typeck.c (chill_expand_case_expr): New function.
12260 Placeholder to implement case expressions.
12261 * ch-typeck.c (chill_expand_result, chill_expand_return):
12262 Handle mode-unspecified tuples and case expressions in
12263 the context of RETURN and RESULT actions.
12264 * chill.y (assignaction): Handle case expressions in the
12265 context of the RHS of an assignment action.
12266 * chill.y (caseaction): Remove spurious duplicate OF in grammar.
12267 * chill.y: Handle labeled structure tuples.
12268 * chill.y: New rules to parse CASE expressions.
12269 * tree.c (build_function_types): Allow Chill functions
12270 to return arrays and functions.
12272 Wed Nov 18 13:50:28 1992 Per Bothner (bothner@rtl.cygnus.com)
12274 * ch-typeck.c (chill_expand_tuple): New function. Expand a
12275 tuple (constructor) given an expected (context) type.
12276 * chill.y: Implement 'LHS := TUPLE' using expand_chill_tuple,
12277 using the mode of the LHS and the expected type of the TUPLE.
12278 * chill.y: Implement initialization.
12279 * chill.y: Fix some syntax bugs (forbidlist must be surrounded
12280 by parentheses), and remove or note ambiguities.
12281 * chill.y: Started converting layout style to be like c-parse.in.
12282 * chill.y: Implement IF expressions.
12283 * chill.y: Added syntax rules for tuples. Labelled and unlabelled
12284 array tuples should now work (in some contexts).
12285 * ch-actions.c: Initialize doing_chill_thang to 1.
12286 * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
12287 initializer, to make pushdecl and finish_decl work.
12288 * c-decl.c (convert_for_assignment): If Chill, don't convert
12289 function and arrays into pointers. (Maybe functions should
12290 still be converted?)
12291 * c-typeck.c (grokdeclarator): Allow functions in Chill
12292 to return arrays and functions.
12294 Mon Nov 16 15:40:47 1992 Per Bothner (bothner@rtl.cygnus.com)

12306 bound of domain if non-zero. Preliminary hook for range checking.
12307 * ch-tree.h, chill.l: Combine variables range_check and
12308 range_check_disabled into global variable range_checking.
