3466 * convert.c (convert_to_boolean): Allow any integral input type.
3468 Sat Sep 24 22:47:54 1994 Per Bothner (bothner@kalessin.cygnus.com)

3478 Wed Sep 21 00:54:21 1994 Per Bothner (bothner@kalessin.cygnus.com)
3480 Give up on trying to use the cleanup mechanism in stmt.c to
3481 make sure the exception handler get unlinked on goto/exit/return.
3482 Instead, do it ourselves. (Much simpler.)
3483 * except.c, ch-tree.h (action_nesting_level): New global.
3484 * ch-tree.h (DECL_ACTION_NESTING_LEVEL): New macro.
3485 * decl.c (define_label): Set DECL_ACTION_NESTING_LEVEL.

3524 * except.c (emit_setup_handler): Add a cleanup to
3525 unlink from exception stack if we return/exit/goto from here.
3526 * loop.c (begin_loop_scope): Move pushlevel from here ...
3527 * parse.c (parse_do_action): ... to here.

3545 * lex.l (readstring): Add processing of control sequence
3546 in character string literals. The granting mechanism writes
3547 this to grant files.

3551 * expr.c (compare_records): In case of -fpack do always
3552 a memcmp instead of comparing each field of the

3566 the entrypoint of a process.
3567 (build_process_header): Change PROCESS arguments to be
3568 like arguments of a function. There will be a wrapper
3569 which is the real entry point for a PROCESS. This wrapper
3570 is automatically build after a PROCESS definition and gets
3571 as argument a pointer to a structure looking like the
3572 arguments of the PROCESS. This wrapper will call the
3573 PROCESS (see build_process_wrapper).
3574 (build_process_wrapper): New function (see above).
3575 (build_start_process): Change processing of arguments.
3576 (tasking_setup): Add processing of a different entry point

3603 will get generated every time a new Makefile will get
3605 * Makefile.in (GNUCHILL_VERSION): Remove it, its defined in
3608 * chill.in: In case of -fgrant-only pass "-S -o /dev/null"
3609 to the compiler to avoid generation of an object file.
3611 Thu Sep 8 12:07:28 1994 Per Bothner (bothner@kalessin.cygnus.com)
3613 * convert.c (display_int_cst), ch-tree.h: New function.
3614 * convert.c (digest_array_tuple): Use digest_int_cst to
3615 provide better error messages. Return error_mark_node on error.
3616 * grant.c (decode_const): Simplify by using digest_int_cst.
3617 * grant.c (format_character, find_assoc): Removed.
3619 * decl.c (do_decl): Add missing TREE_CHAIN.
3621 * decl.c (finish_incomplete_decl): Removed.
3622 (init_decl_processing): Don't set incomplete_decl_finalize_hook.
3623 (finish_decl): Remove old C-specific code to deduce size of
3624 array from initialization.
3625 (complete_array_type): Just make it abort.
3627 * except.c (finish_handler_array): Avoid calling C-specific kludge
3628 complete_array_type.
3630 * convert.c (digest_constructor): Rename, and re-write to:
3631 (digest_array_tuple, convert): No longer use the code in
3632 ../c-typeck.c; use a Chill-only implementation (sigh).
3634 * typeck.c (chill_expand_tuple): Remove unneeded call to
3635 complete_array_type.
3637 * expr.c (fold_set_expr), grant.c (decode_constant),
3638 typeck.c (expand_constant_to_buffer): Update name of called
3639 function unpack_set_constructor to get_set_constructor_bits.
3640 * expr.c (powersetlen ): Remove redundant call to convert.
3642 * ch-tree.h (unpack_set_constructor): Removed obsolete declaration.
3644 * inout.c (build_chill_writetext): Handle 64-bit integer literals
3645 by trying to convert them to a smaller type.
3647 * lex.l (convert_number): Always use long long type (possibly
3648 unsigned) to avoid problems with constant folding truncation.
3650 Mon Sep 5 08:08:22 1994 Wilfried Moser (moser@rtl.cygnus.com)
3652 * ch-tree.h (enum chill_built_in_function): Add BUILT_IN_QUEUE_LENGTH.

3655 * expr.c (build_generalized_call): Add processing of
3656 BUILT_IN_QUEUE_LENGTH.
3658 * tasking.c (build_queue_length): New function.
3660 * tasking.c (tasking_init): Add new external function definition.
3662 Thu Sep 1 15:38:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3664 * lex.l (default_lex): New function. Progress towards
3665 getting rid of [f]lex.
3667 * lex.l (convert_number): Use mul_double and add_double.
3668 Set result type to a reasonable type in which the literal
3669 will fit. Give error message if literal is too big.
3671 * lex.l (equal_number): Switch (temporarily) to permanent obstack.
3673 * typeck.c (build_chill_slice_with_range): Check for empty
3674 slice *after* we have checked for upper/lower limit in range.
3676 * grant.c (decode_mode): Remove unused code. (BOOL and
3677 CHAR ranges are represented as INTEGER_TYPEs.)
3679 * tasking.c (build_process_header): Add missing call to
3680 expand_start_bindings.
3681 * parse.c (end_function): Add missing expand_end_bindings.
3683 Wed Aug 31 17:25:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3685 * decl.c (init_decl_processing): Set set_alignment.
3687 Tue Aug 30 16:40:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
3689 * actions.c (print_missing_cases, check_missing_cases,
3690 BITARRAY_TEST, BITARRAY_SET): New functions and macros,
3691 to check for completeness of case actions and expressions.
3692 * decl.c (c_decode_option, init_decl_processing):
3693 Don't set warn_switch.
3694 * expr.c (chill_expand_case_expr): Call check_missing_cases
3695 instead of check_for_full_enumeration_handling.
3696 * parse.c (parse_case_actions): Call check_missing_cases.
3698 * expr.c (build_chill_binary_op): Remove some dead code.
3699 * expr.c (chill_truthvalue_conversion): Call build_chill_binary_op
3700 instead of build_binary_op.
3701 * ch-tree.h (binary_op_error, build_binary_op): Unused. Removed.
3703 * parse.c (end_function): Use kept_level_p in parameter to
3704 poplevel. This reverts a June 13 change.
3706 Fri Aug 26 11:50:19 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3708 * configure: Ignore --without, as ../configure does.
3710 Wed Aug 24 01:17:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3712 * lex.l: Change rule for decimal numbers to allow identifiers
3713 to start with an underscore (_).
3715 Fri Aug 19 16:38:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
3717 * tasking.c (build_receive_signal_case_label): Remove backwards
3718 chill_convert_for_assignment (which converted whatever garbage
3719 was in the *target* to the type of the signal argument!).
3721 Fri Aug 19 07:10:43 1994 Wilfried Moser (moser@rtl.cygnus.com)
3723 * inout.c (build_chill_io_list_type, build_enum_tables),
3724 tasking.c (build_tasking_struct): Temporarily reset
3725 maximum_field_alignment to 0, so that the compiler-built
3726 data structures needed by the RTS can be independent of -fpack.
3728 Thu Aug 18 13:39:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3730 * typeck.c (build_init_struct): Temporarily reset
3731 maximum_field_alignment to 0, so that the compiler-built
3732 data structures needed by the RTS can be independent of -fpack.
3734 Wed Aug 17 23:48:33 1994 Wilfried Moser (moser@rtl.cygnus.com)
3736 * parse.c (parse_primval, expect, parse_on_exception_list):
3737 Print error message only in pass 2.
3739 Wed Aug 17 13:47:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3741 * decl.c (switch_to_pass_2): Revert June 13 change,
3742 (Don't exit after pass 1 if an error was found.)
3744 * ch-tree.def (SLICE_EXPR): New tree-code.
3745 * typeck.c (build_chill_slice): For building a slice of a
3746 bit-string, just generate a SLICE_EXPR.
3747 * decl.c (init_decl_processing): Declare __pscpy.
3748 * actions.c (chill_expand_assignment): Handle a SLICE_EXPR
3749 on the LHS of assignment, by calling __pscpy.
3750 * expr.c (chill_expand_expr): Handle SLICE_EXPR (as a RHS
3751 value) by using __psslice to copy slice to a temp.
3753 Wed Aug 17 05:52:44 1994 Wilfried Moser (moser@rtl.cygnus.com)
3755 * Make-lang.in: Change version of GNUCHILL compiler to 1.4.1.
3756 * expr.c (build_chill_length): Enable LENGTH built-in to process
3757 Buffers and Events too (Z.200/1992).
3758 * lex.l (yywrap): Always set yyin to finput and/or grt_in. On
3759 a linux system the previous version was not able to run.
3760 * tasking.c: Correct processing of infinite buffer- and event-length
3761 to avoid RANGEFAIL warning.
3763 Thu Aug 11 11:46:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3765 * parse.c (parse_if_expression_body): Don't call the C-specific
3766 build_conditional_expr. Just do build_nt (COND_EXPR, ...).
3767 * convert.c (convert): Convert a COND_EXPR by converting
3770 * convert.c (convert): Don't call convert before
3771 convert_to_reference. It's apt to do weird and unneedful things.
3772 * convert.c (convert): If the expression is varying, just call
3773 varying_to_slice, which simplifies quite a bit.
3775 * ch-tree.h (varying_to_slice): Add prototype.
3776 * typeck.c (varying_to_slice): Remove prototype.
3778 * satisfy.c (satisfy): Move case PAREN_EXPR from type 'e'
3781 * except.c (emit_setup_handler): Temporarily reset the
3782 maximum_field_alignment to zero so the compiler's exception
3783 data structures can be compatible with the run-time system,
3784 even when we're compiling with -fpack.
3786 * expr.c (compare_records): Call saved_if_needed on operands.
3788 * expr.c (build_set_expr case NE_EXPR): Don't use __nepowerset
3789 which has been reimplemented to just call __eqpowerset and
3790 invert the result. Inline this new implementation by
3791 handling as EQ_EXPR, and inverting the result.
3792 * decl.c (init_decl_processing): Don't define unused __eqpowerset.
3794 * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
3795 type boolean_type_node, not void_type_node. (Fixing this
3796 avoids a crash in the back-end.)
3798 * grant.c (decode_constant): In a CALL_EXPR, if the argument
3799 list is not a TREE_LIST (as in string repetiation), don't
3802 Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3804 * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
3805 CONST_DECL is from a SET definition. (This is safer than
3806 checking that the type is ENUMERAL_TYPE, because synonym
3807 definitions may have a NULL TREE_TYPE.)
3808 Also, if we have duplicate enums whose types are identical,
3810 * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
3811 an extra 'quiet' parameter, which is true if we're called from
3812 bind_sub_modules. (In that case an error message about duplicated
3813 decls would be repeated later, so suppress it.)
3815 * parse.c (stmt_count): Removed, not used.
3816 (INIT_ACTION): Call emit_line_note only if !ignoring.
3817 (parse_begin_end_block): Do INIT_ACTION even if ignoring.
3819 Fri Aug 5 12:39:11 1994 Per Bothner (bothner@kalessin.cygnus.com)
3821 * parse.c (parse_untyped_expr): Add missing semi-colon.

3825 * parse.c (parse_untyped_expr): Fix various problem for the
3826 case that we see a '(': Add missing 'case' keyword.
3827 Only recurse if '(' is followed by 'if', 'case' or '[',
3828 and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
3830 * parse.c (parse_send_action): Remove extra nreverse.
3832 Thu Jul 28 04:00:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3834 * expr.c (build_allocate_global_memory_call, build_allocate_memory_call):
3837 Tue Jul 26 22:48:15 1994 Michael Tiemann (tiemann@blues.cygnus.com)
3839 * parse.c (parse_untyped_expr): Added missing "case" before LPRN.
3840 Added a missing call to `require' as well.
3842 Tue Jul 19 10:30:12 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3844 * lex.l (yywrap): Define as yywrap_chill to avoid conflicts with
3845 the extern declaration in the flex skeleton.
3847 Mon Jul 18 23:06:04 1994 Per Bothner (bothner@kalessin.cygnus.com)
3849 * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
3850 Check the type of the instance expr using CH_COMPATIBLE,
3851 and not just == instance_type_node. (This allows
3852 the expression to have mode READ INSTANCE).
3853 * tasking.c (build_instance_type): Give instance_type_node
3854 a non-null novelty (i.e. different from a struct).
3855 * tasking.c (build_receive_case_start, build_delay_case_start):
3856 Check that for a location using CH_LOCATION_P.
3858 Mon Jul 18 13:22:23 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
3860 * expr.c (finish_chill_unary_op): Use TREE_SET_CODE not TREE_CODE
3861 to modify a tree code.
3863 Mon Jul 18 11:24:57 1994 Bill Cox (bill@rtl.cygnus.com)
3865 * convert.c (digest_structure_tuple): Fix thinko in TREE_CODE
3868 Mon Jul 18 05:40:15 1994 Doug Evans (dje@canuck.cygnus.com)
3870 * decl.c (warn_bad_function_cast): Define so cc1chill will link.
3872 Thu Jul 14 18:37:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3874 * parse.c (parse_send_action): Do tree_cons *before* checking
3877 Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3879 * convert.c (digest_structure_tuple): Don't use convert to
3880 coerce initial value, use chill_convert_for_assignment instead.
3881 (Thus we also get range_checking.)
3883 * expr.c (build_chill_card): Use force_addr_of instead of
3884 build_chill_addr_expr.
3886 * loop.c (build_temporary_variable): Stylistic tweak.
3887 * loop.c (maybe_make_for_temp): Initialize temp using
3888 explicitly, not using assignment. Avoids a problem if
3889 the expression is read-only.
3890 * typeck.c (smash_dummy_type): Always used the saved TYPE_NAME
3891 and CH_NOVELTY_FLAG.
3893 Wed Jul 6 20:12:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3895 * expr.c, ch-tree.h (finish_chill_unary_op): New function,
3896 based on code ripped out of build_chill_unary_op.
3897 (build_chill_unary_op): Call finish_chill_unary_op unless pass==1.
3898 * satisfy.c (satisfy): Call finish_chill_unary_op when needed.

3902 * tree.c (save_if_needed), ch-tree.h: New function.
3903 * typeck.c (build_chill_slice_with_range,
3904 build_chill_slice_with_length): Call save_if_neeed on array arg.
3905 * expr.c (varying_to_slice): Re-write to use save_if_needed.
3907 * typeck.c (extract_constant_from_buffer): Handle BOOLEAN_TYPE.
3909 Mon Jun 27 01:11:10 1994 Wilfried Moser (moser@rtl.cygnus.com)
3911 * inout.c (build_chill_io_list_type): Change layout of __tmp_WIO_list
3912 that it is always the same, regardless if compiled with -fpack
3915 Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3917 * lex.l (yywrap): Kludge to work around mis-synchronization
3918 between lexer (which read ahead) and parser: Don't emit
3919 (left-over) uze_seizefile directives at the end of file.
3921 * typeck.c (build_chill_array_ref): Allow the derived
3922 array indexing syntax for arrays of bit strings.
3923 Add a comment explaining why.
3925 * typeck.c, ch-tree.h (string_assignment_condition): Change
3926 the interface. Return a boolean expression (which can be
3927 used in a conditional at run-time); never expand anything.
3929 * actions.c (chill_convert_for_assignment): Check
3930 string_assignment_condition here, rather than in callers.
3931 * actions.c (chill_expand_assignment): Don't need to check
3932 string_assignment_condition here.
3933 * expr.c (build_chill_function_call): Likewise.
3934 * satisfy.c (safe_satisfy_decl): Update accordingly.
3935 * decl.c (do_decl): Simplify testing and conversion by
3936 deferring everything to chill_convert_for_assignment.
3938 * parse.c: Combine the two variables 'ignore_exprs' and
3939 'ignore_actions' into one variable called 'ignoring'.
3940 * ch-tree.h: Add 'extern int ignoring'.
3941 * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
3942 Rename ignore_actions and ignore_exprs to ignoring.
3943 Remove unneeded extern declarations.
3944 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3945 build_chill_arrow_expr, build_generalized_call, build_delay_action,
3946 build_buffer_type, build_event_type): I changed my mind. It is
3947 cleaner to check for 'ignoring' in the parser, rather than here.
3948 * parse.c (parse_action, parse_primval, parse_opt_mode):
3949 Therefore we must check for ignoring here.
3950 * parse.c (parse_loc_declaration): Set ignoring in pass 2
3951 when parsing the mode.
3953 * tasking.c (generate_tasking_code_variable): Do arithmetic
3954 on signal_code etc using unsigned rather than signed shorts.
3956 * grant.c (static char* current_grant_modename): Removed.
3957 * grant.c (decode_decl case CONST_DECL): Remove error message.
3959 * Make-lang.in (CHILL_SRCS): Add $(srcdir)/ch/parse.c.
3960 * Makefile.in: Fix dependencies for parse.o.
3961 Remove some duplicate dependencies for $(TREE_H).
3963 Mon Jun 13 14:25:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3965 * typeck.c (build_chill_cast): Allow a value cast between
3966 non-discrete object of the same size, but with a pedwarn.
3967 * typeck.c (bit_string_assignment_condition,
3968 char_string_assignment_condition): Merge near-duplicate functions
3969 and place the code in string_assignment_condition.
3971 * decl.c (parm_flag, declare_parm_level, in_param_level_p):
3973 * decl.c (start_chill_function, finish_chill_function): Make
3974 parameter level have same nesting level as body, as required by Z200.
3975 * decl.c (switch_to_pass_2): Always exit if an error has been found.
3976 * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
3977 generated from GRANT ALL.
3978 * decl.c (lookup_name_for_seizing): Don't seize from
3979 the nesting level of builtins (predefined objects).
3980 * decl.c (lookup_name_for_seizing): Make more robust on error.
3982 * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
3983 be 'RESULT' (or 'result'). This makes it more accessible from gdb.
3984 Also, use do_decl to declare it, so that debugging symbols are
3985 generated. And, re-arrange so that actions that need to
3986 be done both passes (such as push_levels) use the same code.
3988 * parse.c (get_type_of): If ignore_exprs, don't lookup name.
3989 * parse.c (end_function): Fix poplevel params.
3990 * parse.c (expect): Don't read forwards on an error.
3991 * parse.c (parse_field): Don't define two tag_list locals!
3992 * parse.c (parse_pass_1_2): Better error message.
3994 * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
3995 parse_opt_mode, rather than vice versa. If parse_opt_mode
3996 returns NULL_EXPR, then parse_mode gives an error.
3997 Change parse_opt_mode (and any functions it calls) to only
3998 return NULL_TREE if there is no mode (even on ignore_exprs).
3999 (parse_set_mode, parse_structure_mode, parse_procedure_mode):
4000 Never return NULL_EXPR.
4001 * tasking.c (build_buffer_type, build_event_type): Return
4002 void_type_node instead of NULL_EXPR if ignore_exprs is true.
4004 * parse.c (parse_synonym_definition): Call parse_untyped_expr
4005 only if we have a mode.
4006 * parse.c (parse_send_action): Parse list of untyped_expr's,
4007 rather than a list of (typed) expressions.
4008 * parse.c (parse_primval): Emit error if '[' seen without
4009 preceding mode name. (If this is to be allowed, call
4010 parse_untyped_expr instead.)
4012 * parse.c (parse_array_index): Renamed to ...
4013 (parse_index_mode): ... to match Z200 terminology.
4014 Re-write to resolve some of the nastier ambiguities,
4015 and allow things like ' CHAR(10) : CHAR(20) '.
4017 * parse.c (parse_tuple_element): Change interface to return
4018 reversed list, so don't call nreverse.
4019 * parse.c (parse_tuple): No longer nreverse element list here.
4020 * parse.c (parse_opt_element_list): Do nreverse here instead.
4021 * parse.c (parse_case_label_list): Call nreverse at end.
4023 Fri Jun 10 15:36:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
4025 * typeck.c (chill_similar): Remove bogus "else".
4027 Wed Jun 8 00:01:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
4029 * ch-tree.h (TYPE_ARRAY_MAX_SIZE): New macro (and comment)
4030 to make it clearer that we are using TYPE_MAX_VALUE in a special way.
4031 * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
4032 * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
4033 * convert.c (convert): When converting a fixed string/array
4034 to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
4035 of (the type of) the padding.
4036 * convert.c (convert): If the concatenation is non-constant, use
4037 the low-level 'build' to set the type of the result (which is usually
4038 a fixed-size array) rather than depend on build_chill_binary_op
4039 to figure it out (it's unable to simplify the size to a constant).
4041 Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
4043 * lang.c (lang_decode_option): Let -fspecial_UC imply
4044 -fno-ignore-case without requiring it explicitly.
4045 * lang.c (lang_decode_option): Support (experimentally)
4046 the -fpack and -fno-pack flags.
4048 Thu Jun 2 20:49:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4050 * configure: Add support for --program-prefix and --program-suffix.
4052 Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
4054 * convert.c (digest_constructor): Check that initial value
4055 is compatible with element mode before calling convert.
4056 * typeck.c (chill_compatible): A string mode is not compatible
4057 with an untyped constructor.
4058 * decl.c (do_decl): Clean up error messages. Use error_with_decl.
4060 * ch-tree.h: Fix inconsistencies: bool_true_node ->
4061 boolean_true_node, and bool_false_node -> boolean_false_node.
4062 * typeck.c (valid_array_index_): Minor simplification.
4064 Tue May 31 04:33:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
4066 * inout.c (build_chill_writetext): Add correct processing
4067 of POWERSET RANGE (setmode).
4069 * lex.l (same_file): Add searching for file(s) in
4072 Fri May 27 14:22:42 1994 Per Bothner (bothner@kalessin.cygnus.com)
4074 * Make-lang.c (CHILL.mostlyclean, CHILL.distdir): Don't list
4075 yacc/bison output files, since the grammer is no longer in yacc.
4076 * config-lang.in (diff_excludes): Likewise.
4078 Thu May 26 16:38:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
4080 * gperf, hash.h, lex.l, parse.h: Rename PROCESS_TYPE token
4081 (in some files spelled PROCESS_TYPE_ to avoid clashes
4082 with the PROCESS_TYPE tree_code) to PROCESS_TYPE_TOKEN.
4084 Thu May 26 02:18:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
4086 * timing.c (build_cycle_start): Change call to __define_timeout.
4087 * decl.c (init_decl_processing): Change definitions of
4088 __define_timeout and __wait_timeout.
4090 Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
4092 Replace yacc-based parser with a recursive-decent parser.
4093 (This may seem backwards, but Chill [like C++] is not a
4094 language that is remotely LALR(1). Using a R-D parser
4095 allows us to use look-ahead and to back-up to resolve the
4096 difficult ambiguities.)
4098 * parse.c, parse.h: New files, containing new r-d parser.
4099 * Makefile.in: Update accordingly.
4100 * actions.c (chill_convert_for_assignment): Don't return
4101 NULL_EXPR if ignore_exprs is true. It simplifies the parser
4102 if we consistently reserve NULL_EXPR for a missing expression.
4103 * expr.c (build_chill_function_call): Likewise.
4105 * lex.l: Tweaks for new parser.
4106 * lex.l (prepare_paren_colon, paren_paren_colon_level,
4107 paren_level): Ugly hack no longer needed.
4109 * expr.c (build_chill_function_call): Cleanup.
4110 Call chill_convert_for_assignment to convert IN/INOUT
4111 paramaters on both input and output. For LOC parameters,
4112 give error if actual is a non-referable location.
4113 * actions.c (convert_for_assignment): Add new parameter (a
4114 "place" string used in error messages).
4115 * actions.c (adjust_parm_or_field): Removed.
4116 * actions.c (chill_expand_assignment): Take just a single LHS,
4117 and move support for multiple assignments to ...
4118 (expand_assignment_action): ... here. Some cleaning up.
4119 * timing.c (build_cycle_start): Adjust accordingly.
4120 * actions.c (expand_assignment_to_varying_array): Likewise.
4121 * tasking.c (many places): Ditto.
4122 * ch-tree.h: Fix declarations appropriately.
4124 * parse.c (parse_defining_occurrence_list): Return a single
4125 IDENTIFIER_NODE (instead of a singleton list) in the common
4126 case. Minor complication to save a minor amount of space.
4127 * decl.c (do_based_decls): Move guts of code into ...
4128 (do_based_decl): ... this new function.
4129 * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
4130 * decl.c (push_syndecl): Replace by ...
4131 (push_syndecl): ... (which only supports a single name).
4132 (push_modedef): Only handle a single name.
4133 * tasking.c (build_process_header, build_signal_struct_type):
4136 * expr.c (build_generalized_call): Handle string repetition.
4137 * expr.c (build_chill_repetition_op): Change interface.
4138 * grant.c (decode_constant): Allow parameter list to be
4139 a non-TREE_LIST. (Used for string repetition.)
4141 Wed May 25 11:28:48 1994 Per Bothner (bothner@kalessin.cygnus.com)
4143 * lex.l (make_identifier): Replaced by ...
4144 (read_identifier, handle_name): ... new functions.
4145 * lex.l: Parse an identifiers using read_identifier using
4146 read_identifier and handle_name, rather than having [f]lex
4147 do it. (One reason is that lex uses a fixed-size buffer.)
4149 * lex.l (read_directive, skip_directive): New functions.
4150 Use them to parse compiler-directives, instead of rather
4151 ugly and useless use of lexer start conditions.
4153 Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4155 * decl.c (unnamed_module_number): Renamed to ...
4156 (module_number): .. and make non-static.
4157 (push_module): Always increment module_number.
4158 * lex.l (yywrap): Print warning if no modules seen.
4160 * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
4161 decl to current_seizefile_name (which is unreliable).
4162 * grant.c (chill_grant): Set it here instead.
4164 * expr.c (fold_set_expr): Use int_size_in_bytes instead of
4165 TYPE_PRECISION (which is not defined for a SET_TYPE).
4167 Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
4169 Cleanup to remove need for variables in common storage.
4170 * decl.c: Remove unused use of current_obstack.
4171 * actions.c (maybe_chill_check_decl): Remove unused function.
4172 * actions.h, lang.c: Remove uses of doing_chill_thang.
4173 * ch-tree.h (void_list_node): Make extern (rather than common).
4174 * decl.c (void_list_node): Add definition.
4176 Thu May 19 06:54:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
4178 * configure (build): Build canon_host and canon_target
4179 to pass it to all subsequently generated Makefiles (needed
4180 for testsuite/execute in case of cross build).
4182 Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4184 * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
4185 the input type, which loses with the no-longer-new 2-pass
4186 implementation, since the input "type" could be an IDENTIFIER_NODE.
4187 * grant.c (raw_decode_mode): Rename to decode_mode.
4189 Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
4191 * typeck.c (chill_location): Neither a STRING_CST nor a
4192 CONSTRUCTOR is a location.
4193 * typeck.c (chill_root_mode): Convert a function to a
4194 pointer-to-function.
4195 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
4196 build_chill_arrow_expr): If ignore_exprs, return operand
4197 rather than NULL_EXPR. This makes it easier for the parser to
4198 distinguish missing expressions.
4199 * expr.c (build_max_min): Convert the lower bound of a
4200 set to a long before calling run-time routine.
4201 * expr.c (build_chill_pred_or_succ): Use discrete_type_p
4202 to check the argument type.
4203 * expr.c (build_chill_arrow_expr): If argument is not a location,
4204 do a predwarn if it is a STRING_CST or has function type.
4206 Tue May 17 06:05:13 1994 Wilfried Moser (moser@rtl.cygnus.com)
4208 * configure (build): Remove building of canon_host and canon_target.
4209 It doesn't work in any case.
4211 Mon May 16 02:10:35 1994 Wilfried Moser (moser@rtl.cygnus.com)
4213 * configure (build): Build canon_host and canon_target
4214 to pass it to all subsequently generated Makefiles (needed
4215 for testsuite/execute in case of cross build).
4216 * Make-lang.in (chill-runtime): Change chill to CHILL in the case
4217 statement to build chill-runtime automatically.
4219 Mon May 9 15:30:08 1994 Doug Evans (dje@canuck.cygnus.com)
4221 * Makefile.in (FLAGS_TO_PASS): Define.
4223 (../cc1chill): Depend on $(OBJDEPS) $(C_OBJS).
4224 * Make-lang.in (cc1chill): Delete dependency on $(OBJS) $(BC_OBJS).
4225 (CHILL.mostlyclean): Use `mostlyclean' as recursive target.
4227 Sun May 8 13:05:00 1994 Per Bothner (bothner@cygnus.com)
4229 * Make-lang.in (cc1chill): Should not depend on libgcc.a.
4231 Thu May 5 18:58:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
4233 * decl.c (copy_lang_decl): New (dummy) function.
4235 Mon May 2 14:33:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
4237 * parse.y (sendaction): Fix thinko (in sense of condition).
4238 * tasking.c (build_receive_case_label): Another thinko.
4240 * parse.y (optsigdest): Force ignore_exprs to 0 while parsing
4243 * decl.c (build_chill_function_type): Don't call layout_type
4244 (since that may prevent parameter or result types being
4245 properly satisfied).
4246 * satisfy.c (satisfy): Layout FUNCTION_TYPEs.
4247 * parse.y (procmode): Call build_chill_pointer_type, rather
4248 than build_pointer_type (which incorrectly sets TYPE_SIZE).
4250 * parse.y (get_type_of): Handle TYPE_DECL (again).
4251 * parse.y (optresultspec): Call build_chill_reference_type, rather
4252 than build_reference_type (which incorrectly sets TYPE_SIZE).
4253 * parse.y (range_or_mode): Rename to plain range, since it
4254 no longer matches modename.
4255 * actions.c (chill_handle_case_label_range): New function, with
4256 functionality moved out of chill_handle_case_label.
4257 * actions.c (chill_handle_case_label): Handle here the case that
4258 the label_value is a TYPE_DECL (modename). Also clean up some.
4259 * typeck.c (build_chill_slice_with_length): Convert max_index
4260 to the type of min_value. (Old code broke on varying strings.)
4262 Sun May 1 13:53:36 1994 Doug Evans (dje@canuck.cygnus.com)
4264 * Makefile.in (BC_OBJS): Delete all references
4265 (OBJS): Cat ../stamp-objlist to get language independent files.
4266 (../cc1chill): Delete dependency on $(OBJS).
4267 * Make-lang.in (cc1chill): Depend on stamp-objlist.
4269 Sat Apr 30 14:50:15 1994 Per Bothner (bothner@kalessin.cygnus.com)
4271 * lex.h, lex.c: Remove lastiddecl.
4272 * lex.l (name_type_signal): Simplify. We no longer check for
4273 TYPENAME or SIGNALNAME (which was unreliable with two passes).
4274 Also rename to make_identifier.
4275 * parse.y: Cleaned up grammar to not need SIGNALNAME or TYPENAME.
4276 * Makefile.in (stamp-parse); One conflict fewer!
4277 * parse.y (rccase_label_flag): Moved to tasking.c.
4278 * parse.y (rccase_label): Move most of the logic to
4279 build_receive_case_label in tasking.c.
4280 * parse.y (sendaction): Re-write to not depend on SIGNALNAME.
4282 * parse.y (name): Do name lookup here (and not in location).
4283 * parse.y: Replace most uses of NAME by higher-level non-terminals:
4284 simple_name_string, name_string, defining_occurrence, or name.
4286 * tasking.c (build_receive_signal_case_label,
4287 build_receive_buffer_case_label): New functions, split out from
4288 build_receive_case_label.
4289 * tasking.c (build_receive_case_label): Change parameters
4290 and return type. Moved stuff here (from the parser).
4291 * tasking.c (struct rc_state_type): Removed had_errors.
4292 Return error_mark_node instead.
4293 * tasking.c (build_rccase_set_error), ch-tree.h: Removed.
4295 * expr.c (build_generalized_call): If func is a signal type,
4296 call build_signal_descriptor.
4298 * parse.y (arrayindex): Renamed to index_mode, to match Z.200.
4299 * parse.y (ioindexmode): Removed; use index_mode instead.
4300 * expr.c (build_generalized_call): If args is a RANGE_EXPR,
4301 we have either a slice or a range mode, depending on func.
4302 * parse.y (index_mode): If we got an 'expr', only allow a name,
4304 * parse.y (call): A slice with both end points can be a range
4305 mode, so defer handling to build_generalized_call (or index_mode).
4307 * typeck.c (build_chill_slice_with_length): Fix type-checking.
4308 * typeck.c (chill_novelty): Undo (part of) change of April 28:
4309 The novelty of a range mode is the novlety of the parent.
4310 * typeck.c (chill_root_mode): Don't return integer_type_node
4311 if argument has non-nil novelty.
4313 * decl.c (global_bindings_p): Return -1 as true, for the sake
4314 of variable_size (in ../stor-layout.c).
4316 Fri Apr 29 13:42:43 1994 Per Bothner (bothner@kalessin.cygnus.com)
4318 * parse.y: Remove TYPENAME and modename. These are now plain
4319 NAMEs. Modify parsing actions appropriately.
4320 * expr.c (build_generalized_call): Handle the case that
4321 TREE_CODE (func) == TYPE_DECL (as in a cast).
4322 * lex.l (name_type_signal): Never return TYPENAME.
4323 * parse.y (get_type_of): If pass 1, just return the argument.
4325 * decl.c (do_decl): If an initializer has the wrong type,
4326 replace it by NULL_TREE, to avoid subsequent errors.
4328 Thu Apr 28 15:21:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
4330 * Makefile.in: Add new file timing.c to rules.

4357 * tasking.c (build_receive_buffer_case_end, build_receive_signal_case_end):
4358 New functions to process the end of a RECEIVE CASE action in case
4359 of BUFFER's and SIGNAL's.
4360 * tasking.c (build_receive_case_end): Do only general processing and
4361 call one of the above mentioned functions.
4362 * tasking.c (build_delay_case_start, build_delay_case_label,
4363 build_delay_case_end): Rewritten due to new implementation of events.
4364 * tasking.c (build_delay_action): Rewritten due to new implementation

4370 Thu Apr 28 14:11:29 1994 Per Bothner (bothner@kalessin.cygnus.com)
4372 * typeck.c (smash_dummy_type): Handle the special case of a
4373 NEWMODE of a range mode, as required by Z200, by creating a
4374 new parent mode with the new novelty (and casting the min
4375 and max of the range to teh new parent mode).
4376 * typeck.c (chill_novelty, chill_root_mode): Remove special
4377 kludges for of NEWMODE ranges.
4378 * expr.c (build_chill_lower_or_upper): New function, combining
4379 the "guts" of build_chill_lower and build_chill_upper.
4380 * expr.c (build_chill_lower_or_upper): Simplify; no longer
4381 need to kludge the novelties.
4383 * typeck.c (valid_array_index_p): A string index expression
4384 need not be Compatible with the index type; only similar.
4386 * decl.c (layout_chill_variants): If error seen, skip stuff
4387 (rather than aborting or crashing).
4388 * decl (push_modedef): If newdecl's type is an error mark,
4389 continue rather than aborting.
4391 Thu Apr 28 02:07:42 1994 Doug Evans (dje@cygnus.com)
4393 * Make-lang.in: Update of directory reorg from fsf.
4394 * config-lang.in: Ditto.
4396 Mon Apr 25 13:09:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
4398 * typeck.c (chill_similar): Check RECORD_TYPEs properly,
4399 * convert.c (convert): If all else fails, just call convert1.
4400 Thus we can now convert RECORD_TYPEs (assuming they are similar).
4402 * parse.y, lex.l: Remove BUFFERNAME (use location/expr instead).
4403 * parse.y: Re-do BUFFER handling (similar to previous EVENT change).
4404 * grant.c (raw_decode_mode): Re-do BUFFER mode handling.

4411 to name and simple_name_string. This removes a reduce/reduce conflict.
4412 * Makefile.in (stamp-parse): Expect fewer conlicts.
4414 * lex.l (yywrap): Move check for circularly seizeing current
4415 grant-file from here ...
4416 * lex.l (handle_use_seizefile_directive): ... to here.
4417 This is to avoid calling stat on a not-yet written grantfile,
4418 now that we're using same_file (which calls stat).
4419 * grant.c (set_use_this_gf): Removed.
4420 * grant.c (set_default_grant_file): Set grant_file_name here,
4421 because we need it earlier (due to above lexer change).
4423 * typeck.c (layout_chill_struct_type): Remove useless code to
4424 remove zero-width bitfield (which messes up CONST_DECLs).
4426 Sat Apr 23 13:16:39 1994 Bill Cox (bill@rtl.cygnus.com)
4428 * Makefile.in (check): Assure that 'ld' is available before checking.

4436 * parse.y (event_list): Fix syntax.
4437 * parse.y (optqueuesize): Default is NULL_TREE, not zero.

4439 * ch-tree.h: Add declaration for check_queue_size.
4440 * satisfy.c (satisfy case RECORD_TYPE): Satisfy constant fields
4441 (used for queue size of EVENT and BUFFER), and call check_queue_size.

4445 Re-implement EVENT modes to support general EVENT objects
4446 (and not just EVENT names), according to Z200. (Not finished!)
4447 * tasking.c, ch-tree.h (max_queue_size): New function.
4448 * parse.y (dcalternative, event_list, event_list_head): New

4456 * tasking.c (build_delay_action): Preliminary changes - just to
4457 make it compile. FIXME!
4458 * grant.c (raw_decode_mode): Use new max_queue_size function.
4459 Move EVENT support from LANG_TYPE to RECORD_TYPE.
4460 * ch-tree.h (process_event_decls): Removed.
4462 Tue Apr 19 11:44:01 1994 Bill Cox (bill@rtl.cygnus.com)

4467 Mon Apr 18 10:17:55 1994 Bill Cox (bill@cygnus.com)
4469 * Makefile.in (check): Simplified regression.sh call.
4470 * regression.sh: Change command-line parsing. Default
4471 srcdir to the script's path. Calculate objdir
4472 internally - don't pass it in.

4496 * lex.l (chill_same_grant_file): Rename to same_file. Change to
4497 take two files names rather than two DECLs. Also check that the
4498 filesystems (st_dev) are equal. Finally, make static.
4499 * lex.l (handle_use_seizefile_directive): Check for duplicate
4500 USE_SEIZE_FILE directives using same_file.
4501 * decl.c (pop_module): Remove dubious call to chill_same_grant_file.

4508 Use chill_result_decl appropriately.
4509 * ch-tree.h, decl.c, actions.c (saved_result_rtx): Removed.

4517 * actions.c (chill_expand_assignment): Check for compatibility
4518 _after_ "expanding out" a binary operation. This fixes
4519 the case "STRING //:= CHAR".
4521 * lex.l (equal_number): Convert symbol to integer_type_node, to
4522 force the value to be INT-derived (and avoid novelty conflicts).
4524 Mon Apr 4 22:06:31 1994 Per Bothner (bothner@cygnus.com)
4526 * ch-tree.h (CH_FUNCTION_SETS_RESULT): New flag.

4574 * tasking.c (make_process_struct): Change error message in case of
4575 a process argument has other attribute then IN or LOC.
4576 * tasking.c (build_start_process): Add check that the optset is
4577 referable in case it is specified (this makes
4578 noncompile/start_.ch working).

4626 * typeck.c (build_chill_modify_expr): Simplify.
4628 Sun Mar 27 19:30:25 1994 Bill Cox (bill@rtl.cygnus.com)

4662 Wed Mar 23 13:34:18 1994 Bill Cox (bill@rtl.cygnus.com)
4664 * expr.c (build_generalized_call): Revert previous change.
4665 To do this correctly, we need a new parsing mechanism, and

4728 Mon Mar 21 13:29:23 1994 Per Bothner (bothner@kalessin.cygnus.com)
4730 * typeck.c (layout_chill_range_type): Instead of tree_int_cst_lt

4735 * expr.c (chill_expand_expr): Code to expand SET_IN_EXPR,
4736 moved from expand_expr in ../expr.c. Also add some extra

4742 with code moved from build_compare_expr.
4743 * expr.c (build_compare_expr): Re-enable compatibility test.

4767 list for __setbitpowerset,
4769 * typeck.c (chill_compatible_classes): Allow the M-reference
4770 to be compatible with the N-value class, with suitable M and N.
4771 * typeck.c (build_chill_slice): Don't smash a void TREE_TYPE.
4772 (We don't need to, and it causes confusion.)
4774 * expr.c (build_compare_expr): Fix thinko. Add save_exprs.
4776 * expr.c (build_compare_expr): Fix a transcription bug
4777 (for converting NULL INSTANCEs). Also #include convert.h.
4779 * expr.c (compare_int_csts): New. Compare INTEGER_CSTs.
4780 Works even if their types have different TREE_UNSIGNED.
4781 * expr.c (finish_chill_binary_op): Moved code dealing with
4782 the comparison operators from here ...
4783 * expr.c (build_compare_expr): ... to new function here.

4788 * typeck.c (valid_array_index_p): Various cleanups,
4789 including using new build_parse_expr.

4807 * expr.c (build_chill_pred_or_succ): Fix cond tree
4808 to have consistent operand types.
4809 * typeck.c (valid_array_index_p): Change interface to pass
4810 validity conditions back on caller's TREE_LIST. We
4811 cannot link the conditions to anything which a
4812 layout_type routine will expand, since that will occur
4813 before the exception handler is set up.
4814 Change calls to valid_array_index_p also.
4816 Fri Mar 18 14:40:50 1994 Per Bothner (bothner@kalessin.cygnus.com)

4823 * convert.c, expr.c: Re-write to avoid calls to C-specific
4824 function build_unary_op (e.g. by calling build1 directly).

4829 * typeck.c, ch-tree.h (build_chill_slice): Make non-static.
4830 * expr.c (varying_to_slice): Call build_chill_slice (and not
4831 build_chill_slice_with_length, which does bunches of range
4832 checking and does not allow the length to be zero).
4833 * convert.c (convert): Fix off-by-one error.
4834 * actions.c (chill_expand_array_assignment): Minor cleaning up.
4836 Fri Mar 18 00:12:48 1994 Per Bothner (bothner@deneb.cygnus.com)

4839 take *two* pointer parameters, not one.
4840 * satisfy.c (satisfy): Only call the appropriate layout routine
4841 if TYPE_SIZE is 0 (i.e. type hasn't already been laid out).
4842 * typeck.c (build_chill_slice_with_length): Fix Bill's previous fix.
4844 Thu Mar 17 17:29:43 1994 Bill Cox (bill@rtl.cygnus.com)
4846 * expr.c (build_chill_function_call): Give function call the correct
4848 * typeck.c (build_chill_slice_with_length): Restore dynamic range
4849 checking, so it doesn't obscure the CONSTANTness of the length.
4851 Wed Mar 16 17:23:31 1994 Per Bothner (bothner@kalessin.cygnus.com)
4853 * typeck.c (build_chill_slice), expr.c (chill_expand_expr
4854 [case CONCAT_EXPR]): Remove kludge setting slice size upper bound
4855 in TYPE_LANG_SPECIFIC, and restore kludge setting it in MAX_VALUE.
4856 * typeck.c (build_chill_slice): Use TYPE_MAX_VALUE of
4857 array_type if needed for size upper bound of slice_type.
4858 * expr.c (build_concat_expr): Improve calculation of size upper bound.
4860 * typeck.c (valid_array_index_p): Check compatibility using
4862 * typeck.c (build_chill_slice_with_length); For now revert
4863 calling valid_array_index_p on length. (It makes it harder
4864 to realize when the slice is constant length.)
4865 * expr.c (build_chill_indirect_expr): Minor tweak. (This
4866 seems to work around a weird C compiler bug. ??)
4868 * expr.c (build_chill_function_call): Cleanup so it doesn't
4869 call build_function_call (in c-typeck.c).
4870 * typeck.c, expr.c: Use build_chill_function_call instead of
4871 build_function_call (in c-typeck.c).
4873 * parse.y (discrete_mode): Move some of the rules from
4874 non_array_mode into new non-terminal.
4875 (arrayindex): Use discrete_mode (with NAME and TYPENAME) to
4876 avoid some misparses.
4877 * ch-tree.h (SLICE_PTR, SLICE_LENGTH): Removed; unused.
4878 * convert.c (digest_structure_tuple): Add missing parameter.
4879 * decl.c (comptypes): Remove unused prototype.
4880 * decl.c (build_chill_function_type): Handle NULL return_type
4881 correctly (convert to void_type_node).
4882 * decl.c (init_decl_processing): layout boolean_type_node *after*
4883 we've set it's TYPE_MIN_VALUE and TYPE_MAX_VALUE.
4885 Wed Mar 16 16:08:22 1994 Bill Cox (bill@rtl.cygnus.com)

4888 * convert.c (convert): Correct calculation of padding length.
4889 * decl.c (grok_chill_fixedfields): Move ignore_exprs test to
4890 parse.y where it belongs. This permits the removal of a kludge
4891 in make_process_struct.
4892 * lex.l, parse.y: Call to_global_level for several errors. Add
4893 code to output error in only one pass.
4894 * tasking.c (make_process_struct): Delete kludge inserted on

4901 (build_rts_call): Ifdef it out - never used.
4902 (expand_varying_length_assignment): call valid_array_index_p.
4903 rather than validate_varying_array_ref.
4904 * ch-tree.h: Fix prototype for valid_array_index_p.
4905 * expr.c (chill_expand_expr): Call build_chill_array_ref to get
4907 (build_hill_lower, build_chill_upper): Return value now inherits
4908 the novelty of the input parameter.
4909 (varying_to_slice): Use CH_NOVELTY macro rather than calling
4910 chill_novelty directly.
4911 * grant.c (newstring): Make len unsigned and cast xmalloc parameter
4913 (print_integer_type): Pass string value as APPEND's second parameter.
4914 (decode_decl): Pass a boolean expression as print_proc_tail's
4916 (chill_finish_module_code): Make xmalloc's parameter unsigned.
4917 * lex.l: Pass sizes to xmalloc as unsigned ints. Pass second
4918 parameter to in_word_set as unsigned.
4919 * loop.c (build_loop_start): Check top_loop_end_check return value.
4920 * parse.y: Add casts to int for third do_decls parameter, fifth
4921 build_loop_iterator parameter, etc.
4922 * tasking.c (build_receive_case_end): Chack cond_stack before popping.
4923 * typeck.c (validate_varying_array_ref, chill_max_vary_array_index,
4924 valid_array_index): Delete them. They're now unused.
4925 (valid_array_index_p): Add function, call it everywhere that an
4926 array index is checked.
4927 (build_chill_slice): Restore old functionality where varying_to_slice
4928 is called to handle slices of varying arrays, rather than handling
4930 (build_chill_slice_with_range, build_chill_slice_with_length):
4931 Check range limits for TREE_CONST before calling tree_int_cst_lt.
4932 Delete now-obsolete checks of constant indices.
4934 Mon Mar 14 17:26:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4936 * parse.y (modeless_expr): New rule to allow ([...]) and (if...)
4937 to count as untyped_exprs. (This is not really permitted by the
4938 Blue Book, but has been requested by customers.)
4940 Thu Mar 10 10:11:02 1994 Bill Cox (bill@rtl.cygnus.com)
4942 * chill.texi: Document new command-line options.
4943 * expr.c (build_chill_num): Set unsigned parameter for
4944 type_for_size call correctly (unsigned for enums).
4945 * lang.c (lang_decode_option): Add command-line options to
4946 enable/disable runtime range-checking.
4947 * lex.l: Eat more whitespace.
4949 Thu Mar 10 09:41:37 1994 Bill Cox (bill@rtl.cygnus.com)
4951 * Makefile.in: Have rules to make parse.h, y.tab.c and other
4952 derived files. This allows the gcc/configure list of CHILL
4953 files machinery to work.
4954 * ch-tree.h (permanent_allocation): Add a parameter flag.
4955 * decl.c (finish_chill_function, finish_decl): Provide the
4956 new permanent_allocation flag.
4957 (poplevel): Return early, avoid a seg fault.
4958 * lex.l (NORMAL): Replace this whole state with the predefined
4959 INITIAL state. Force compilation state to global level after
4960 compiler directive error - prevents endless loop on error.
4961 (handle_use_seizefile_directive): Rewrite for readability.
4962 (chill_same_grant_file): Reindent.
4963 Generally handle whitespace differently.
4964 * regression.prpt: Print ten PR numbers per line. The report's

4969 * decl.c (do_decl): Suppress the string-assignment-condition
4970 error - it was too often seen.
4971 * expr.c (expand_chill_expr): In CONCAT_EXPR, when argument has a
4972 runtime-changing length (as in a slice), get the parent array's
4973 allocation size from its type tree.
4974 * typeck.c (build_chill_slice): Support VARYING arrays. Pass
4975 parent array's static allocation size along in the slice type.
4977 Wed Mar 9 08:54:24 1994 Bill Cox (bill@rtl.cygnus.com)
4979 * lex.l (name_type_signal): Avoid dereferencing a NULL TRE_TYPE.
4981 Tue Mar 8 11:51:10 1994 Bill Cox (bill@rtl.cygnus.com)
4983 * expr.c (build_chill_sizeof): Fix typo in error msg, add
4985 * lex.l (name_type_signal): Add debug output.
4986 * parse.y (call): Allow EVENTNAME and BUFFERNAME parameters
4987 to a call, so that SIZE () works on them.
4988 * tasking.c (make_process_struct): Force ignore_exprs non-zero
4989 when processing a SEIZEd PROCESS declaration. This prevents
4990 grox-fixed_fields from returning a NULL, and indirectly protects
4991 the chill_integer_type_node tree from corruption.
4993 Mon Mar 7 19:14:05 1994 Bill Cox (bill@rtl.cygnus.com)
4995 * Makefile.in: Use the 'all' target to build the runtime
4996 library and chillrt0.o.

4999 chill.regress.cron: Move to utils subdirectory.
5000 * expr.c (build_chill_function_call): Mark the INOUT
5001 temporary so it doesn't get optimized into a
5002 register. Fixes the execute/inout.ch bug.
5003 * typeck.c (layout_chill_range_type): Restrict it
5004 from complaining about an empty string type's
5007 Mon Mar 7 09:06:39 1994 Bill Cox (bill@rtl.cygnus.com)

5040 * lex.l (INITIAL): Remove all code to discard 'header lines'.
5042 * parse.y (optheader): Remove - it's obsolete, as is the
5043 HEADEREL token definition.
5045 Fri Mar 4 09:41:18 1994 Bill Cox (bill@rtl.cygnus.com)
5047 * addtest: Fix suffix removal when suffix is .c186.

5067 range-checking code. Handle reference_type in convert call.
5068 (chill_expand_assignment): Produce an INDIRECT_REF for a

5142 name for correctness.
5144 Wed Feb 23 15:07:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
5146 New cleaner solution to the following problem:
5147 Chill allows an action to be followed by an ON-handler.
5148 But we don't know if an action has a handler until we've parsed
5149 its end, yet we want to generate extra code to set up an
5150 exception handling contour only if needed. The old solution
5151 would generate code for the action into an rtl sequence, and then
5152 splice in the exception-setup code if we later found we needed it.
5153 This has a few problems (for example it confuses the management
5154 of stack temporaries), and is ugly. Now that the compiler is 2-pass
5155 we have a cleaner solution: In pass 1, we remember which actions
5156 were followed by ON-handlers. In pass 2, we use this information
5157 to generate appropriate code before an action.
5158 * except.c (push_handler, pop_handler): In pass 1, set up data
5159 structures (global_handler_list) to remember if an action has an
5160 ON-handler. In pass 2, digest this information, and setup
5162 * except.c, actions.h (pop_handler): Take an extra int arg.
5163 * except.c (emit_setup_handler): New function, with code (moved
5164 from chill_start_on) to emit code before an action that has a handler.
5165 * except.c (except_init_pass_2): New function.

5167 * parse.y (POP_UNUSED_ON_CONTEXT): Don't call pop_sequence.
5168 * parse.y: Invoke POP_UNUSED_ON_CONTEXT and POP_USED_ON_CONTEXT
5169 in pass 1 as well as pass 2.
5170 * parse.y (BEGIN ... END): Re-arrange logic to avoid block_stack
5171 (local to ../stmt.c) getting out of sync.
5172 * actions.c (push_action): Don't need to emit a NOP,
5173 now that we're no longer moving sequences around.
5174 * actions.c (push_action): Call push_handler even in pass one.
5176 Wed Feb 23 11:06:14 1994 Bill Cox (bill@rtl.cygnus.com)

5275 index list to single index. Call layout_chill_array_type
5276 if pass!=1. And rename to: build_simple_array_type.

5278 if TREE_TYPE has not been laid out.
5279 * typeck.c (build_chill_array_type): Update accordingly.
5280 * typeck.c (build_chill_slice): Replace calls to build_array_type

5283 * convert.c (convert): The same.
5285 * grant.c (decode_constant): Clean up. Remove remnants of switch

5307 * build-release: Add refinements to checkout commands.

5810 * ch-actions.c, ch-expr.c, ch-typeck.c: Make operand 1 of a
5811 VARY_ARRAY_REF is a single index, not an index list.
5813 * ch-grant.c (__init_list): Renamed to _ch_init_list, to
5814 avoid a conflict on the Alpha.

5818 * ch-lex.l (WS): Add BS, VT and CR to definition of
5820 (convert_number): Allow for uppercase hex digits.

5827 * ch-grant.c (chill_finish_module_code): Avoid abort by
5828 giving the init_list constructor a type.
5829 (chill_finish_compile): Delete unused code.
5830 * ch-lex.l: Make most build_init_2 calls from the
5831 permanent obstack, so that enumeration values endure.

5838 'struct ch_class class = chill_expr_class (expr);' to
5839 'struct ch_class class; class = chill_expr_class (expr);'
5840 to work around a bug in /usr/ucb/cc on SunOS4.
5842 Mon Jan 10 18:29:36 1994 Bill Cox (bill@rtl.cygnus.com)
5844 * ch-actions.c (chill_convert_for_assignment): Avoid seg fault.
5845 * ch-expr.c (expand_packed_set): Add new parameter to pass

5867 (Patches from Tiemann.)
5868 * ch-convert.c (convert1): New function to force TREE_TYPE.
5869 (convert): Use convert1 where appropriate.
5870 * ch-typeck.c: Formatting change.
5871 * ch-parse.y (build_chill_constructor): Fix thinko.
5873 * ch-expr.c (varying_to_slice): If array is not referable,
5874 call save_expr on it, rather than stabilize_reference.
5875 * ch-satisfy.c (safe_satify_decl, for CONST_DECL):
5876 Don't force value to value class if mode is not explicitly
5877 specified. Also, make sure convert etc is only done once.
5879 Sat Jan 8 16:37:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
5881 * ch-decl.c (build_chill_function_type): Don't call
5882 build_function_type, because it does hash canonicalization,
5883 which once in a while looses badly.

5885 for doing_chill_thang.
5887 * ch-tree.h (CH_DERIVED_FLAG): New flag.

5901 convert_float, convert_number): Set CH_DERIVED_FLAG for literals.
5902 * ch-expr.c (finish_chill_binary_op): Use convert_to_class.
5903 * ch-satisfy.c (safe_satisfy_decl): For CONST_DECL, make sure
5904 DECL_INITIAL gets set to result of convert.
5905 Also, clear CH_DERIVED_FLAG for SYN value.
5906 * expr.c (store_constructor): If a [power]set is exactly one
5907 word long, use single-word move.
5909 Sat Jan 8 08:38:29 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5911 * c-typeck.c (chill_initializer_constant_valid_p): Fix typo.

5924 for unary set operations).
5926 * ch-expr.c (build_chill_array_expr): Take new argument FORCE. All
5927 callers changed. All callers changed.
5929 * ch-convert.c (digest_structure_tuple): Handle SELECTED_VARIANT
5930 being NULL_TREE until we've started walking the list of values via
5931 the loop over VARIANTs.
5933 * ch-parse.y (build_chill_constructor): If we see an IDENTIFIER_NODE,
5934 treat it as an enum value (and hence constant). Also, only set
5935 TREE_STATIC if the constructor is indeed constant.
5936 * c-typeck.c (chill_initializer_constant_valid_p): If we see a
5937 VAR_DECL, test the TREE_CONSTANT field of the DECL_INITIAL, don't
5938 recurse on the DECL_INITIAL.
5940 Wed Jan 5 01:24:50 1994 Bill Cox (bill@cygnus.com)
5942 * Makefile.in: Add CHILL to LANGUAGES variable.
5943 * ch-actions.c (check_range): Call build_binary_op instead of
5944 fold, build to get the common types chosen.
5945 (cond_range_exception, cond_overflow_exception,
5946 cond_type_range_exception): Delete, obsolete.
5947 (chill_convert_for_assignment): Enable this, get particular
5948 about when to generate rangecheck code.
5949 * ch-expr.c (build_chill_function_call): Sketch in where to
5950 perform chill_convert_for_assignment on actual parameters.
5951 (build_chill_addr_expr): Correct compiler warning.
5952 * ch-loop.c (build_chill_iterator): Add runtime check for
5953 negative loop step expression.
5954 * ch-tree.h: Add prototype.
5955 * ch-typeck.c (chill_max_vary_array_ref): Correct misunderstanding.
5956 A varying array's length field counts the NUMBER of active array
5957 array entries, not the byte-length of them.
5959 Tue Jan 4 17:57:39 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5961 * ch-decl.c (do_decl): Call `suspend_momenary' if the
5962 converted constructor must live on the permanent_obstack.
5963 * ch-convert.c (convert): When building a new SET_TYPE
5964 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5965 * c-typeck.c (chill_initializer_constant_valid_p): Handle VAR_DECLs.
5967 * ch-typeck.c (chill_location): CONSTRUCTORS that are static

5970 on permanent_obstack if necessary.
5972 * ch-convert.c (digest_structure_tuple): When building a new SET_TYPE

5978 * ch-expr.c (build_chill_arrow_expr): Call `mark_addressable'.
5979 (build_chill_addr_expr): Take new argument ERRORMSG.
5980 All callers changed. Also, call `build_chill_addr_expr' where
5981 we used to call `build1 (ADDR_EXPR, ptr_type_node, ...)' since
5982 that now calls `mark_addressable' automagically.
5984 * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.
5985 This is needed because variables may appear in initialization
5986 statements, and their DECL_INITIALs are their values at
5987 initialization time.
5988 * ch-convert.c (digest_structure_tuple,digest_constructor): Changed
5989 to handle VAR_DECLs as initializers.
5991 * ch-convert.c (digest_structure_tuple): Copy elements of INITS so
5992 they aren't destroyed for later use.
5994 Tue Jan 4 15:25:30 1994 Bill Cox (bill@cygnus.com)
5996 * ch-expr.c (chill_expand_expr): Correct check-range lo_limit
5997 parameter for varying_array_ref calculations.
5998 (build_chill_indirect_ref): Prevent seg fault due to syntax error.
5999 * ch-typeck.c (build_chill_slice_with_range): Correct issuance
6000 of bogus error in votrics.
6001 (build_chill_slice_with_length): Change for debug tracability.

6005 * ch-convert.c (digest_structure_tuple): Fix phasing problem in
6006 handling variant record initializers.
6007 (various places): Change `pop_init_level' calls to match
6008 `push_init_level' wrt implicit variable.
6010 * ch-typeck.c (build_chill_slice): Convert the dynamic max index to
6011 `integer_type_node' before using it in comparisons. FIXME: should
6012 this be done in `chill_max_vary_array_index' by default?
6014 Tue Jan 4 00:24:14 1994 Bill Cox (bill@cygnus.com)
6016 * ch-actions.c: Fix comments.
6017 * ch-parse.y: Define caseaction_flag.
6018 (caseaction): Create new caseaction_flag node at the start,
6019 then free it at the end. Check it before the ELSE code.
6020 (expanded_case_label): Check the flag here. If set in either
6021 place, generate a jump to the end of the case.
6022 * ch-typeck.c (build_chill_slice_with_length,
6023 build_chill_slice_with_range): Add lots of compile-time
6024 parameter range checking.
6026 Mon Jan 3 21:49:04 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6028 * ch-convert.c (digest_structure_tuple): Call `push_init_level' with
6029 implicit==0 everywhere, not 1.
6030 (digest_constructor): Ditto.
6032 * ch-actions.c (check_range): Permit limits to be NULL_TREE.
6033 Also, hack out some dead code.
6034 * ch-typeck.c (build_chill_slice): Check varying and non-varying
6035 slice constructs for range failures.
6036 (build_chill_slice_with_range): Reindented, but not changed.
6038 * ch-typeck.c (chill_max_vary_array_index): New function.
6039 * ch-expr.c (chill_expand_expr): Call it.
6041 * ch-decl.c (var_data_id, var_length_id): New variables.
6042 (init_decl_processing): Initialize them. All calls to
6043 get_identifier (VAR_LENGTH or VAR_DATA) are now replaced
6044 by references to these variables. This simplifies the code
6045 w/o obscuring anything.
6047 Mon Jan 3 21:24:44 1994 Bill Cox (bill@cygnus.com)
6049 * c-typeck.c: Fix comment.
6050 * ch-actions.c (chill_expand_assignment): Error assigning to
6051 READONLY location. (PR_3903) Pass filename, linenumber
6052 to setbitpowerset runtime routine.
6053 * ch-decl.c (init_decl_processing): Add filename, linenumber
6054 parameters to setbitpowerset prototype.
6055 * ch-expr.c (build_chill_function_call): Error when passing a
6056 READonly location as a LOC or INOUT parameter.
6057 * ch-parse.y (mode): Correct code marking type as readonly.
6059 Mon Jan 3 19:03:55 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6061 * ch-actions.c (chill_expand_assignment): Disable code that defeats
6062 building varying array references.
6063 * ch-expr.c (chill_expand_expr): Add rangecheck code to
6064 VARY_ARRAY_REF case.
6065 * ch-typeck.c (build_chill_array_ref): Don't call an `expand_'
6066 function (in this case, `validate_varying_array_ref') when we're
6067 doing a `build_' operation.
6069 * ch-typeck.c (validate_varying_array_ref): Simplify interface
6070 since INDEX parameter can never meaningfully be an INDEXLIST.
6071 * ch-actions.c (expand_varying_length_assignment): Caller changed.
6073 Mon Jan 3 07:29:45 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6075 * ch-typeck.c (build_chill_cast): Set TREE_CONSTANT on NOP_EXPRs.
6076 * ch-convert.c (digest_structure_tuple): Switch to permanent_obstack
6077 if we need to build a CONSTRUCTOR for a SET_TYPE initializer.
6078 (digest_structure_tuple): If TREE_VALUE (VALUE) == NULL_TREE, don't
6079 call CH_COMPATIBLE or try to convert it to TREE_TYPE (FIELD). This
6080 can happen when constructors are output incrementally.
6081 * c-typeck.c (initializer_constant_valid_p): Handle SET_TYPEs.
6082 * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
6085 Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6087 * ch-convert (digest_structure_tuple): Handle SET_TYPEs. Also, call
6088 `convert' so we can handle INSTANCE types (and other anomolies)
6091 * ch-convert.c (digest_structure_tuple): Fixed variant
6092 structure initialization. Also fixed a typo (TYPE_NAME
6093 was being used on a FIELD_DECL instead of DECL_NAME).
6094 * c-typeck.c (initializer_constant_valid_p): Pass missing
6095 ENDTYPE argument on recursive call.
6096 (set_init_field): New function, needed by ch-convert.c change above.
6098 * ch-decl.c (layout_chill_variants): Added a FIXME next to an
6099 almost certain typo.
6101 * ch-expr.c (build_chill_arrow_expr): Call `build1' and set
6102 TREE_CONSTANT for static references.
6103 * ch-except.c (chill_start_on): Change calls to
6104 `build_unary_op' (which is C-specific) to `build_chill_arrow_expr'
6105 which has CHILL semantics.
6106 * ch-convert.c (convert): Ditto (albeit in some disabled code).
6108 Sat Jan 1 21:26:43 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6110 * ch-satisfy.c (safe_satisfy_decl): Reorder conditional test of
6111 TREE_CODE of DECL in case it's altered by actions in the switch.
6113 * ch-satisfy.c (satisfy): Undo abort added earlier on 1 Jan. CVS log
6114 mentions where to find code that triggers this case.
6116 * ch-actions.c (adjust_parm_or_field): Handle CONSTRUCTORS here as
6119 * ch-convert.c (digest_structure_tuple): Push to permanent_obstack if
6120 we're dealing with a CONSTRUCTOR that is TREE_PERMANENT.
6121 (digest_constructor): Ditto.
6123 Sat Jan 1 10:29:19 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6125 * ch-parse.y (handleraction,resultaction,assignaction,call): Modified
6126 so that CONSTRUCTORS are properly handled before being used.
6128 * ch-convert.c (chill_start_init): New function. All callers to
6129 `start_init' changed to call this function instead.
6130 (digest_struct_tuple): Defend against initialization machinery
6131 mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
6132 IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
6133 needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
6134 can be refered to throughout the compilation unit. Also remove an
6135 extraneous call to `process_init_element' erroneously added to the
6136 variant record sub-loop.
6137 (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
6138 CONSTRUCTORS of SET_TYPE.
6139 * ch-parse.y (build_chill_constructor): Refix typo. Also set
6140 TREE_STATIC if at top level.
6142 * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
6143 TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
6144 should have been called.
6146 * ch-convert.c (digest_struct_tuple): Restore code which tracks
6147 field initializations so that the compiler can deduce what variant
6148 initializations to assume.
6150 * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
6151 when we push into a scope that has a DECL with a CONSTRUCTOR as its
6154 * ch-parse.y (build_chill_constructor): Change the name of the
6155 parameter to something more meaningful. Fix typo. Also, handle case
6156 where element is an untyped CONSTRUCTOR.
6158 * ch-except.c (finish_handler_array): Set TREE_CONSTANT on
6159 constant ADDR_EXPRs.
6160 (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT
6161 on JBUF_REF (instead of calling `build1' which does not).
6163 * ch-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
6165 * ch-typeck.c (chill_expand_tuple): Deleted.
6166 * ch-parse.y (primval rule): Don't call `chill_expand_tuple';
6167 instead, use initialization machinery for CONSTRUCTORS that
6169 * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
6170 that are created here.
6171 * ch-satisfy (satisfy): Abort in case we would have called
6172 chill_expand_tuple. FIXME: some other code is needed here,
6173 but I don't know what yet.
6175 * ch-parse.y (build_chill_constructor): New function to
6176 propagate TREE_CONSTANT bits to CONSTRUCTORS.
6177 (untyped_expr rule): Use it.
6178 (primval rule): Use it.
6180 * ch-decl.c (do_decl): Call `finish_init'.
6181 * ch-convert.c (convert): If we spontaneously create a CONSTRUCTOR in
6182 this function, make sure the initialization machinery is set up.
6184 * ch-convert.c (digest_structure_tuple, digest_constructor): Add
6187 Fri Dec 31 11:31:01 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6189 * ch-grant.c (chill_finish_module_code): Mark ADDR_EXPR built by hand
6190 as being TREE_CONSTANT. Otherwise it gets bounded by the initializer
6193 * ch-decl.c (do_decl): Change in CONSTRUCTOR handling due to...
6194 * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
6195 rewritten to work with GCC's initialization code. The basic change
6196 was to keep the initializers in sync with the initialization
6197 machinery that `process_init_element' imposes. Both of these
6198 functions now return `void'.
6199 * ch-convert.c (convert): Changed calls to `digest_...' functions.
6201 FIXME: the code handling UNION_TYPE (and variant records) has not
6204 Fri Dec 31 15:32:56 1993 Bill Cox (bill@rtl.cygnus.com)
6206 * ch-lex.l (convert_number): Output the converted number if

6211 Fri Dec 31 13:17:48 1993 Bill Cox (bill@cygnus.com)
6213 * ch-parse.y: Cleanup handling of RETURN actions, to distinguish
6214 a RETURN without a value (which cannot have an exception
6215 handler) from a RETURN with a value (which can). Eliminate
6216 some shift/reduce and reduce/reduce conflicts.
6218 Thu Dec 30 17:42:32 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6220 * ch-inout.c (build_chill_writetext): Deal with 2 cases where
6221 types returned from `type_for_size' are not expected. FIXME.
6222 * ch-decl.c (init_decl_processing): Mark `char_type_node' unsigned.
6223 This is required when range checking is enabled.
6225 Thu Dec 30 14:28:25 1993 Bill Cox (bill@rtl.cygnus.com)
6227 DELAY CASE works now.
6228 * ch-decl.c (init_decl_processing): Move rest of tasking-related

6248 failed full regression testing.
6249 * ch-lex.l (name_type_signal): Add debug output.
6250 * ch-parse.y (structured_variable): Add a debug variable.
6252 Wed Dec 29 02:05:51 1993 Bill Cox (bill@rtl.cygnus.com)
6254 * ch-decl.c (get_next_decl): Revert change which failed full

6259 DELAY actions work now.
6260 * ch-decl.c: Correct spelling in comments.
6261 (get_next_decl): NULL out the decl's TREE_CHAIN before returning

6264 * ch-expr.c (build_chill_indirect_ref): Prevent a syntax error from
6265 becoming a seg fault.

6272 (locdec): process event decls here, too.
6273 (mode): Add code to forbid READonly EVENT and BUFFER decls. Delete
6274 code which required EVENTs and BUFFERs to be declared at global scope.
6275 (simple_name_string): Add an EVENTNAME.

6292 options. Delete C-specific defines. Disable piping from
6293 pre-processor to cc1chill (even if -pipe is specified), since cc1chill
6294 rewinds its input for its second pass. Piping still works
6295 from cc1chill to as.

6335 distinguish a string from a char array, and to distinguish a
6336 bitstring from regulat (power)set. (Needed for Chill.)
6337 * dbxout.c (dbxout_type): Only check for baseclasses in
6338 type.binfo is a vector. (It is used in Chill for tagged unions.)

6360 * ch-tree.h: Fix prototypes.
6361 * ch-typeck.c (smash_dummy_type): Handle all four kinds of LANG_TYPE

6379 (non-seize) declarations are proclaim_decl'd *before* we
6380 handle the ALIAS_DECLs for seizes. The advantage is
6381 that we can now test for (an approximation) to the

6383 when a module has both GRANTs and SEIZE ALL.
6385 * ch-expr.c (build_chill_arrow_expr): No longer re-write

6396 * ch-expr.c (finish_chill_binary_op): Use CH_ROOT_RESULTING_MODE
6397 macro (which works on expressions), rather than CH_RESULTING_MODE

7026 * ch-decl.c (lookup_name): Recognize WITH_DECLs.
7027 * ch-decl.c (handle_one_level): Variant parts are currently

7114 code variables associated with a process or signal.
7115 * ch-tasking.c (build_gen_inst, build_gen_ptype): Use the decl's

7132 (print_mode): Use CHILL upper-case convention to print modes.
7133 * ch-lex.l: Must initialize tasking-related trees to NULL at start
7134 of each pass, or we lose the fact that the user did or did not
7135 specify a value for each of them.
7136 * ch-parse.y (check_end_label, action, exceptlist): Only output
7137 error message in pass 1.
7138 (sendaction): Add comments.

7146 parameter to know whether to include an init expression.

7163 generation for decls to not use DECL_ASSEMBLER_NAME.
7164 * ch-decl.c: Set DECL_ASSEMBLER_NAME to DECL_NAME.
7165 This matches C, and allows dbxout to emit proper user-level names.
7166 (It would be cleaner to fix dbxout to use DECL_NAME ...)

7214 Sun Oct 17 15:16:54 1993 Bill Cox (bill@cygnus.com)
7216 * ch-convert.c: Move semicolon to separate line - easier to see.
7217 * ch-decl.c (do_decl): Handle untyped_expr initializers by
7218 simply using the variable's declared type - no compatibility
7219 check can be made if the expression has no type.

7222 (fold_set_expr): Fix two other endless loops by passing
7223 correct parameters to unpack_set_constructor.

7357 * ch-loop.c (build_temporary_variable, begin_for_range,
7358 init_loop_counter): Add parameter to decl_temp1 call.
7359 * ch-parse.y (quasi_signaldef): Clear quasi_signal flag here,

7409 * ch-parse.y (end_function): Use DECL_ARGUMENTS to check
7410 for parameterless process.
7412 Fri Oct 1 13:57:30 1993 Per Bothner (bothner@kalessin.cygnus.com)
7414 * ch-typeck.c (chill_location): New function.
7415 Based on lvalue_p, but also handle Chill-specific VARY_ARRAY_REF.
7416 * ch-typeck.c, ch-tree.h (CH_LOCATION_P), ch-convert.c: Use
7417 chill_location instead of lvalue_p.
7420 Fri Oct 1 11:28:42 1993 Bill Cox (bill@cygnus.com)

7436 ch-convert.c (convert): Use it.
7437 * ch-typeck.c (build_chill_slice): Take length rather than upper
7438 bound. This makes it easier to recognize that A(X UP LENGTH)
7439 really has fixed length. Also, if the argument is string,
7440 mark the slice as a string too. Also, handle varying strings.
7442 * ch-typeck.c (conflate_singleton_strings): New global.
7443 * ch-typeck.c (chill_similar): If conflate_singleton_strings is
7444 set (as it currently is), allow CHARS(1)/BOOLS(1) to be similar

7449 * ch-convert (maybe_turn_scalar_into_arra), ch-tree.h: Removed.
7450 * ch-convert.c (convert): Convert CHAR to CHARS(1).
7452 This fixes 'X // := Y' and is also a general simplification.
7453 * ch-actions.c (chill_expand_assignment): Convert 'LHS OP := RHS'
7454 to 'LHS := LHS OP RHS' (using stabilize_reference on LHS).
7455 Also, call save_expr on RHS if a multiple assignment.
7456 * ch-parse.y (assignaction): Therefore, no longer need to call
7457 stabilize_reference on RHS.
7458 * ch-typeck.c (build_chill_modify_expr), ch-tree.h: Remove
7459 modifycode parameter. Make it the caller's responsibility to

7471 * ch-tree.c (build_string_type): Pass string_index_type_dummy as
7472 the parent type of the index range.
7473 * ch-typeck.c (layout_chill_range_type): Recognize and handle
7474 string_index_type_dummy - specifically allow an empty range.

7478 * ch-convert.c (convert_to_reference): Check for loc-identity
7479 mismatches correctly (and remove one of those chill_compatible
7481 * ch-decl.c (decl_tasking_code_var): New function, called from
7482 push_extern_process and push_extern_signal.
7483 * ch-parse.y (end_function): Delete parameter. Check current_function_decl
7484 whether it's actually a process, and whether it has parameters.
7485 Make Michael's change simplifying the pass 2 test, preventing a seg
7487 (procedure, process): Change calls to end_function, remove
7488 code saving value from build_process_header. Delete redundant chill_
7489 phrases from some function calls.
7490 * ch-tasking.c: Remove some redundant _chill phrases from function
7492 * ch-tree.h: Remove some redundant _chill phrases from function
7493 names. Add the CH_VARYING_ARRAY_TYPE macro, call it from
7494 all relevant places.
7495 * ch-typeck.c: Use the new macro. Cast TREE_CODEs to chill_tree_code.
7497 Wed Sep 29 13:07:43 1993 Per Bothner (bothner@kalessin.cygnus.com)
7499 * ch-convert.c (convert_to_reference): Remove redundancies.

7501 with a recursive convert call.
7502 * ch-decl.c (do_decl): Add missing compatibility-checking
7503 of initializer (don't depend on convert).
7505 Tue Sep 28 00:02:25 1993 Per Bothner (bothner@kalessin.cygnus.com)
7507 * ch-tree.h (CH_LOCATION_P): New macro.
7508 * ch-typeck.c (layout_chill_range_type): Fix call to
7509 type_for_size, when figuring out a defaulted parent type.
7510 * ch-expr.c (build_chill_lower, build_chill_sizeof): Check
7511 for TREE_CODE_CLASS != 't' rather than == 'd'.
7512 * ch-expr.c (build_chill_function_call): Use CH_LOCATION_P
7513 to check for location, rather than TYPE_CODE_CLASS == 'd'.
7515 * ch-tree.c (build_string_type): Make 2-pass safe. Also,
7516 change parameter to be length, not index type.
7517 * ch-parse.y (mode2), ch-expr.c (build_concat_expr), ch-lex.l
7518 (build_chill_string): Modify callers of build_string_type accordingly.
7519 * ch-lex.l (check_newline): Don't look for # directive inside a
7521 * ch-grant.c (grant_array_type): Make more robust for char-
7522 and bit-strings (allow non-constant sizes). Change parameters
7523 and return types. (raw_decode_mode): Use grant_array_type
7524 for bitstrings. (otherwise): Fix grant_array_type callers.
7526 Mon Sep 27 16:57:57 1993 Per Bothner (bothner@kalessin.cygnus.com)
7528 Remove changes of Sep 15.
7529 * ch-tree.h (CH_SINGLETON_DOMAIN): Removed.
7530 * ch-typeck.c (chill_similar): Don't allow a singleton
7531 powerset to be similar to its domain.
7532 * ch-convert.c (convert_to_boolean): Don't convert a singleton
7533 SET_TYPE constructor to a Boolean.
7535 * ch-actions.c (chill_expand_assignment): Handle IN_EXPR on
7536 LHS of assignment, which is what we're current (temporarily?) using.
7538 Mon Sep 27 06:01:57 1993 Bill Cox (bill@rtl.cygnus.com)
7540 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
7541 ch-grant.c, ch-inout.c, ch-parse.y, ch-satisfy.c,
7542 ch-tasking.c, ch-tree.c, ch-tree.h, ch-typeck.c:
7543 -Wall cleanup. Add prototypes where missing.
7544 Delete unused variables. Cast uses of tree_codes
7545 to chill_tree_code, which they are.
7547 Sun Sep 26 13:09:57 1993 Bill Cox (bill@rtl.cygnus.com)
7549 * ch-decl.c (do_decl): Save initializer in pass zero
7551 * ch-lex.l: Fix comments, indentation.
7552 * ch-parse.y: Standardize error messages to use
7553 uppercase for CHILL keywords rather than quoting them.
7554 Suggestion from docs department.
7555 * ch-tasking.c: Pervasive changes to get processes to
7557 * ch-tree.h: Delete prototypes for functions whic
7558 I made static inside ch-tasking.c.
7560 Sun Sep 26 02:40:02 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7562 * ch-lex.l (yywrap): Call `check_newline' in case the file
7563 started with a line directive.
7565 Sat Sep 25 13:54:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
7567 * ch-decl.c: Expand pre-amble comment.
7568 * ch-decl.c (struct scope, push_module): Use new field
7569 tail_chain_module to build child-module list in order.
7570 (Just to make compiler debugging a little less confusing.)
7572 * ch-decl.c (struct scope): New field weak_decls.
7573 * ch-decl.c (find_implied_types): New interface. Now pre-pend
7574 new enum types to a given input list. This makes it easier to
7575 avoid duplicates, which should at least be more efficient.
7576 Also, handle FUNCTION_DECL.
7577 * ch-decl.c (bind_saved_names): Removed. Distribute its
7578 functionality over new functions (push_scope_decls, pop_scope_decls,
7579 build_implied_names, bind_sub_modules). The goal (which seems to
7580 have been more-or-less attained) was to fix weak name handling.
7581 * ch-decl.c (poplevel): Use new function pop_scope_decls.
7583 * ch-tasking.c (build_signal_struct, build_tasking_message_type):
7584 Use build_decl directly, rather than grok_chill_fixedfields
7585 (which depends on ignore_exprs and has more overhead).
7586 * ch-tasking.c (build_signal_struct): Construct the type
7588 * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
7589 than build_array_ref (which does C-specific "optimizations").
7590 (Hence move my_build_array_ref up earlier in the file.)
7592 Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7594 * ch-tasking.c: Declare static variable `void_ftype_void'.
7595 (chill_tasking_init): Initialize `void_ftype_void' here.
7596 (build_tasking_struct): Use, don't declare `void_ftype_void'.
7597 (generate_tasking_code_variable): Call `do_decl', not
7598 `decl_temp1' to declare TASKING_CODE_NAME.
7599 (tasking_setup): Drop into 1-pass mode so that all
7600 tasking-related declarations are installed in the global
7601 scope. Use correct CHILL types for initializers (since
7602 ptr_type_node doesn't have the right meaning for CHILL).
7603 Also, call `do_decl' instead of `decl_temp1' for
7605 (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
7606 `chill_finish_compile' in sync between passes.
7608 * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
7609 declarations on pass zero. Keep obstacks in sync, and always
7610 call `finish_decl' for pass zero declarations.
7611 (push_chill_extern_function): Keep obstacks in sync, and always
7612 call `finish_decl' for pass zero declarations.
7613 (build_enumerator): Ditto.

7625 extra pushing and popping of obstacks.
7627 * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
7628 on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
7630 * ch-grant.c (chill_finish_compile): Clear out both
7631 MODULE_INIT_LIST and TASKING_LIST if either contains stuff
7634 * ch-parse.y (rccase_label): Add NAME rules so that pass one
7635 works w/o knowing we're parsing a signal. Simplify SIGNALNAME
7636 rules since we only get SIGNALNAME tokens in pass two.
7637 (sendaction): Ditto.
7638 * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
7639 BUFFERNAME on pass two. The grammar now handles this.

7642 Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
7644 * ch-decl.c (lookup_remembered_names): Removed. It was being
7645 misused in ch-lex.l.
7646 * ch-lex.l (name_type_signal): Revert last change. Basically,
7647 we cannot use the C typedef/variable name trick in CHILL, due
7648 due to the language's 2-pass nature.
7649 * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
7651 * ch-tree.h (lookup_remembered_name): Comment out the prototype.
7653 Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)

7664 * ch-parse.y: Set pass to zero to indicate initial decl processing.
7665 Replace NAME references with SIGNALNAME references.
7666 (startaction): Only check copy number if not ignoring actions.
7667 Always call build_chill_start_process.
7668 (optstartset): Don't lookup the instance name.
7669 * ch-tasking.c (generate_tasking_code_variable): Replace
7670 do_decl call with decl_temp1 call.

7675 (build_chill_receive_case_start, build_chill_receive_case_end):
7679 Fri Sep 24 04:19:15 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7681 * ch-tasking.c (build_chill_receive_case_start): `namedecl'
7682 should be a _DECL, not an IDENTIFIER_NODE.

7705 ALIAS_DECL the name in the most recent use_seize_file directive.
7706 (This requires that use_seize_file directives written to the
7707 grant file be written before the SEIZEs that need it.)
7708 Allow clashing declarations granted into the global scope
7709 (produce a warning), but remember the seizefile case from
7710 (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
7711 The a SEIZE will select the granted decl that matches its
7712 DECL_SEIZEFILE (in other words: grants from the most recent
7713 use_seize_file will be preferred).
7714 * ch-tree.h (DECL_SEIZEFILE), ch-tree.def: New macro.
7715 * ch-tree.h (global_value, IDENTIFIER_GLOBAL_VALUE): Renamed

7720 Changed to have type TREE_LIST of pointer to IDENTIFIER_NODE.
7721 * ch-lex.l (handle_use_seizefile_directive): Modify appropriately.
7722 Don't call grant_use_seizefile.
7723 * ch-lex.l (mark_use_seizefile_written): New function.
7724 * ch-grant.c (decode_decl): Write out use_seize_file directive,
7725 if needed, before writing a seize declarations.

7727 module specially, setting IDENTIFIER_OUTER_VALUE.
7728 * ch-decl.c (lookup_name_for_seizing): Check IDENTIFIER_OUTER_VALUE.

7783 * ch-satisfy.c (safe_satisfy_decl): Disable copying of modes
7784 for NEWMODE (and hence novelty checking), until we figure out

7846 doing the type's layout.
7847 (processpar): Use paramnamelist, but reformat it into a

10323 * ch-grant.c (chill_finish_module_code): Since module
10324 function is no longer visible,, can't get it using
10325 lookup_name(). Use current_function_decl instead.
10327 * ch-decl.c (build_chill_function_type): Add void_type_node
10328 to end of parameter types list.
10330 * ch-grant.c (chill_start_module_code): Make sure module

10401 (start state 'ccitt'): Deleted, unused. Moved unused, but reserved,
10402 tokens to NORMAL state.
10403 (compiler_directive): Replaced by equal_number. Now the only
10404 recursive call to yylex happens in check_newline at the beginning
10407 Sat Apr 10 09:55:50 1993 Bill Cox (bill@rtl.cygnus.com)
10409 * ch-actions.c (build_chill_case_expr): Added from ch-parse.y.
10410 * ch-lex.l (ENTRY, PERVASIVE, ROW, STEP): Add token recognition to

10419 Sat Apr 10 01:10:51 1993 Per Bothner (bothner@rtl.cygnus.com)
10421 * ch-parse,y (in_pseudo_module): New variable. Try if we're
10422 in a seizefile, but not in a module nested in the seizefile.

10441 action statements; semicolons are now optional a number of
10443 * ch-parse.y: Remove some bogus tests for "statement
10444 out of sequence" (they're both legal and work).
10445 * varasm.c (mak_function_rtl): Remove kludge that may
10446 not be necessary (and loses anyway).
10448 Fri Apr 9 09:37:38 1993 Bill Cox (bill@rtl.cygnus.com)
10450 * ch-expr.c (chill_expand_array_assignment): Remove false error about

10501 * ch-decl.c (push_parms): Use new massage_param_node().

10548 Fri Apr 2 21:55:14 1993 Per Bothner (bothner@rtl.cygnus.com)
10550 Major re-write of New module/seize/grant stuff.
10551 Now, a grantfile is a spec module and contains all the
10552 top-level declarations of the granting module, not just
10553 those that are granted. It also contains explicit grant
10554 statements naming those declared names that are granted.
10555 It also has seize statements and use_seize_file directives
10556 to correctly handle transitive dependencies.
10558 * ch-parse.y: Change to allow multiple modules per source file.
10559 Allow spec modules (including quasi definitions) as well as
10561 Allow spec modules inside normal modules; these behave as if
10562 they were outermost. This violates the Blue Book, but is
10563 needed by the new grantfile mechanism. (A grant file is a
10564 spec module that gets included by the use_seize_file directive.)
10565 * ch-parse.y (struct module *current_module, push_module,
10566 pop_module): Support module nesting (for spec modules only).
10568 * ch-tree.h (struct module): New.
10569 * ch-grant.c (granted_decls): New list of declarations
10570 that have been granted into the outermode pseudo-module.
10571 * ch-grant.c (decode_mode): If the decl has a name,
10572 always write the name, not just if the decl has already
10573 been written. Since we write out all decls, we can assume
10574 it will be written later, and depend on the forward
10575 declaration kludges to catch it.
10576 * ch-grant.c (decode_decl): Don't write out _EXTERN.
10577 Instead write out standard (Blue Book) quasi-definitions.
10578 * ch-grant.c (push_granted): New function.
10579 * ch-grant.c (seize_implied_names): New function. Re-write
10580 how set element names are seized when a set type is seized.
10581 * ch-grant.c (chill_seize): Work by seraching the
10582 granted_decls list and copying the declaration.
10583 * ch-grant.c (chill_grant): Write all declarations
10584 declared in this module. Write GRANT statements for
10585 those granted. seize statements for decls seized from
10586 other modules. Write extra syntax to make a complete
10588 * ch-grant.c (grant_use_seizefile): Copy use_seize_file
10589 directives into grant file.
10590 * ch-lex.l (setup_seizefile_read): Call grant_use_seizefile.
10592 * ch-lex.l (struct input_state, current_input_state,
10593 push_input_file, pop_input_file): New (type, variable,
10594 function*2). Used to save and restore state on an input file.
10595 * ch-lex.l: Clean up to handle nested input seizefiles
10596 (needed by new grant/seize mechanism.
10597 * ch-lex.l (skip_to_end_of_directive): New function.
10598 * ch-lex.l (compiler_directive: USE_SEIZE_FILE): Make sure
10599 we skip to the end of the directive *before* we switch
10601 * ch-lex.l (setup_seizefile_read): Prevent reading the
10602 same seizefile twice (otherwise likely with new grant/seize).
10603 * ch-lex.l: Recognize SPEC. Misc cleanups.
10605 * ch-parse.y: Fixed foreward references of types.
10606 Removed the unknown_type_node crock.
10607 * ch-decl.c: Remove all uses of unknown_type_node.
10608 Check for TYPE_SIZE zero instead.
10609 * ch-decl.c (fixup_unknown_type): Make sure new mode
10610 gets copied into old mode. Merge their variant chains.
10611 * c-decl.c (lookup_name_current_level): Make non-static.
10612 * ch-decl.c (lookup_name_current_level): No longer needed.

10615 name following the CALL keyword.
10616 * ch-tree.h (struct lang_identifier): Add implicit_decl,
10617 and make sure order of fields matches c-tree.h.
10619 * ch-actions.c (lang_init, build_allocate_memory_call,
10620 build_allocate_globals_memory_call): Fix names (add initial '_')
10621 and prototypes of _allocate_[global_]memory (2nd param is ref).
10622 Use build_chill_function_call, not build_function_call,
10623 so the reference parameter gets handled.
10624 * ch-actions.c. (lang_init): Make sure boolean_{true,false}_node
10625 have boolean_type_node as their types.
10626 * ch-actions.c (build_chill_lower, build_chill_upper): Fix to
10627 work for arrays with BOOLEAN_TYPE ranges (and simplify some).
10629 * ch-except.c: Make sure an end_label is generated,
10630 and jump to it if there is no exception.
10632 * ch-convert.c (convert_to_reference): Strip off NOP_EXPR casts.
10633 * expr.c (expand_expr): Handle NOP_EXPR as Chill-style casts.
10634 (Need cleaning up and FSF installation!)
10635 * ch-parse.y: If taking the address of a cast, move the
10636 ADDR_EXPR inside the NOP_EXPR.
10638 * ch-typeck.c (my_build_array_ref): Simplified, more suitable
10639 versions of build_array_ref from c-decl.c. (E.g. don't barf
10640 if index type is char or bool.)
10641 * ch-typeck.c (build_chill_array_ref): Use my_build_array-ref.
10643 * ch-typech.c (build_chill_bin_type): New function.
10644 Support BIN(N) range type specification.

10649 that range types are similar to their parent types.
10651 * ch-tree.h: Declare flag_local_loop_counter.
10652 * ch-loop.c: Whether the loop variable is local to the loop
10653 in now controlled by flag_local_loop_counter, instead of

10655 * ch-actions.c (lang_decode_option): Recognize flags
10656 "-f[no-]local-loop-counter".
10657 * toplev.c (lang_options): Add Chill flags -f[no-]local-loop-counter.
10659 * varasm.c (make_function_rtl): Due to problems with forward
10660 references, don't rename nested functions in Chill. (Kudge!)
10662 Sun Mar 28 10:12:45 1993 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10664 * ch-lex.l (push_back, readstring): Fix prototypes.

10686 as-yet-undeclared types. Check for IDENTIFIER_NODE, lookup its
10687 DECL if there, pass TREE_TYPE of decl to build_pointer_type.
10688 (variantfields, varianthack): Clean up.
10689 (variantfield): Check for IDENTIFIER_NODE, lookup its DECL if
10690 there, pass TREE_TYPE of decl to grok_fixedfields.

10725 array and its type get on the permanent obstack.
10726 * ch-grant.c (write_grant_file): Don't write the _INIT=name

10728 characters in the chill_initializer_name).
10729 * ch-decl.c (push_synmode): Set TYPE_NAME(mode) = syndecl.
10730 * ch-lang.c (finish_chill_enum): Don't allocate a dummy
10731 TYPE_DECL for the enum. I don't think it is needed (?),

10736 * ch-grant.ch (raw_decode_mode): New function, based on old
10738 * ch-grant.c (decode_mode); This is now just a wrapper around

10748 after each statement. Move convert call into
10749 chill_expand_assignment from ch-parse.y.
10750 * ch-grant.c: Generally re-order, clean up. Include Per's decode_mode
10751 simplification. Include commented-out hack in decode_mode to return

10768 * ch-parse.y (structured_variable): Return NULL_TREE is invalid WITH
10769 parameter is seen, don't count it in structured_variable_list. Pre-
10770 vents seg fault when only WITH operand is invalid.
10771 * ch-parse.y (label_spec): Correct assignment within IF expression which
10772 was intended to be equality test. Remove unused variables.
10773 * ch-tree.h: Add prototype. Remove unused EXCP_CODE enumeration, and
10774 prototyping editorial comments.
10775 * ch-typeck.c: Disable generation of code to validate array index for
10776 now. Should be done as a call-back from more generic array_ref code.
10777 Clean up parameter checking. Remove unused variables.

10899 * expr.c (expand_expr): Use actual library name for __inpowerset
10901 * stor-layout.c (variable_size): Disable complaint about variable-

10914 remove handling of CHAR arrays - they're handled in build_char_array_expr.

10916 need bitcount instead.

10925 build_chill_length: Move VARYING array handling before regular char
10927 * ch-expr.c chill_expand_expr: Disable concatenate code - we need to
10928 the VARYING status of the target to do this correctly. Use powersetlen
10929 for the powerset operations, not a byte length.
10930 * ch-loop.c: Make CREATE_SCOPE #define to enable creation of a new scope
10931 for each CHILL loop, as Z.200 requires. Add powerset and error flags
10932 to loop structure. Evaluate user's powerset expression into a temp,
10933 scan it destructively with __ffsetclrpowerset or __flsetclrpowerset
10934 for powerset loop. Only do loop-end assignments if NOT a powerset
10935 loop, which has much less overhead now.

11211 New types chill_integer_type_node and chill_unsigned_type_node
11212 that correspond to the Chill source types INT and UINT.
11213 For now, these match the C 'short' types, but that should
11214 become a configuration option later,

11236 * ch-tree.def: add a new tree type - just for varying array
11237 references. We were using ARRAY_REF, but the underlying C
11238 code also generates that one.

11469 chill front end to distinquish between true string types and
11470 arrays of char, since it uses ARRAY_TYPE for both, rather than
11471 trying to use the existing support for STRING_TYPE.

11598 * ch-parse.y: tiny cleanup.
11600 Wed Jan 6 13:25:33 1993 Bill Cox (bill@cygnus.com)
11602 * modules: use gdb rather than naked-gdb, to get opcodes
11603 in chill definition.
11605 Wed Jan 6 09:48:35 1993 Bill Cox (bill@cygnus.com)
11607 * ch-typeck.c: add code to handle references to elements of VARYING
11608 arrays. Simplify chill_give_type_to_expr. Add rough draft of run-
11609 time index checking for VARYING arrays (under #if 0).
11610 * ch-actions.c: new function cond_type_range_exception & calls.
11611 New function cond_range_exception, for more general range-checking.

11613 for the special varying field names.
11614 * ch-tree.h: define macros for varying field names.
11615 * ch-expr.c: use macros for varying struct names. Simplify
11616 chill_expand_array_assignment.

11630 Move shared code into ...
11631 * ch-decl.c (start_chill_function): ... here.
11632 * ch-decl.c (start_chill_function): Add missing call to
11633 expand_start_bindings.

11645 Mon Jan 4 17:57:48 1993 Per Bothner (bothner@cygnus.com)
11647 * ch-grant.c, ch-parse.y: Remove all code for explicitly
11648 calling initializer functions. This is not needed, since we
11649 use the same mechanism used for C++ static constructors.
11650 * ch-grant.c (chill_start_module_code): Make sure the
11651 init_name starts with the magic string also used for C++
11652 initializers. Also, don't embed the file name in the name,
11653 just use the module name.
11654 * ch-grant.c (chill_finish_module_code): Now that the
11655 initializer name follows the standard 'collect' convention,
11656 don't need to call assembler_constructor_alias, but can
11657 use the standard assemble_constructor instead.
11658 * varasm.c (assemble_constructor_alias): Remove no-longer-
11660 * ch-parse.y: Move code that is common to the beginning of
11661 all functions to a new macro INIT_ACTION.
11662 Make sure INIT_ACTION is also done for callaction, fixing a bug.
11663 * ch-parse.y (INIT_ACTION): Do chill_start_module_code()
11664 before emit_line_note(), not after.
11666 Mon Jan 4 11:43:12 1993 Bill Cox (bill@cygnus.com)
11668 * ch-parse.y: restore requirement for :upper-bound in array decl.
11669 * ch-actions.c: enhance upper, lower, length functions for VARYING.
11671 Mon Jan 4 09:28:44 1993 Bill Cox (bill@cygnus.com)

11682 Sun Jan 3 11:57:13 1993 Bill Cox (bill@cygnus.com)
11684 * ch-typeck.c: correct & enable array index range-checking
11686 Sun Jan 3 11:36:39 1993 Bill Cox (bill@cygnus.com)
11688 * ch-parse.y: define IGNORED_DIRECTIVE
11689 * ch-typeck.c: subtract array's lower domain value, even if
11690 index expression is constant.
11692 Sat Jan 2 23:05:14 1993 Fred Fish (fnf@cygnus.com)
11694 * ch-lex.l (convert_float): Fix misspelling in error message.
11696 Sat Jan 2 16:02:16 1993 Per Bothner (bothner@rtl.cygnus.com)
11698 * Makefile.in: Took out chill-runtime support.
11699 Chill run times are now in ../chillrt, not ./chillrt.p
11701 Sat Jan 2 15:04:13 1993 Bill Cox (bill@cygnus.com)
11703 * ch-hash.h, chill.gperf: cleanup. fewer keywords seen by ch-parse.y.
11705 Sat Jan 2 13:27:49 1993 Per Bothner (bothner@rtl.cygnus.com)
11707 * ch-lex.l (check_newline): Use the orginal versions (derived
11708 from the C code, not the simplified, special-case version).
11709 Also, fix that version of check_newline to not call yylex()
11711 * ch-lex.l (yy_input): Call check_newline to handle
11712 newlines and check for # directives.
11713 * ch-lex.l (syntax): Don't recognize #-directives; these
11714 are now handled by check_newline.
11715 * ch-actions.c (lang_init): Call the modified version of
11716 check_newline(). Do this at the *after* we've initialized
11717 standard types, so this can be done while lineno is still 0.
11719 Sat Jan 2 10:57:20 1993 Bill Cox (bill@cygnus.com)
11721 * ch-hash.h, chill.gperf: add remaining reserved words.
11723 Sat Jan 2 09:59:55 1993 Bill Cox (bill@cygnus.com)
11725 * ch-tree.h, ch-parse.y, ch-lex.l: add remaining reserved words,
11726 names for exceptions
11728 Fri Jan 1 12:30:31 1993 Fred Fish (fnf@cygnus.com)
11730 * ch-tree.h (JOINER): Define joiner character the same way
11732 * ch-grant.c (chill_start_module_code): Use JOINER character
11733 to implement name mangling for the initializer function name.
11734 Algorithm is designed to be simple, distinct from C++ mangled
11735 symbols, and easy to convert to demangled form.
11737 Thu Dec 31 10:30:51 1992 Bill Cox (bill@rtl.cygnus.com)
11739 * ch-expr.c: make array assignments work with indirect refs.
11740 * ch-actions.c: prepare for array parameter handling.
11741 * ch-loop.c, ch-parse.y, ch-tree.def, ch-typeck.c: clean up.
11743 Thu Dec 31 15:29:20 1992 Per Bothner (bothner@rtl.cygnus.com)
11745 * ch-lex.l (yy_input): Re-write to return more than one
11746 character at a time (execpt when reading seize-files).
11747 Don't increment lineno until we start reading the next line.
11748 This fixes some off-by-one errors in lineno.
11750 Wed Dec 30 16:15:23 1992 Per Bothner (bothner@rtl.cygnus.com)
11752 * ch-convert.c: Assume use of new common.c.
11753 * ch-convert.c (convert_to_reference, convert_from_reference):
11754 New routines, to handle loc-identity declared variables and
11755 LOC parameters (both of which are implemented as references).
11756 * ch-lang.c (convert_to_boolean, convert_to_char): Move to
11757 ch-convert.c, where they would seem to belong.
11758 * ch-convert.c (convert): New function, since we no longer
11759 link in c-convert.c.
11760 * ch-expr.c (chill_expand_assignment): Handle by calling
11761 convert() instead of chill_comptypes().
11762 Also handle the LHS being a reference.
11763 * ch-parse.y: Add a procedure call as an action.
11764 * ch-parse.y (locdec, optlocinit): Move handling of
11765 loc-identity declarations from optlocinit to locdec
11766 - and add working semantics for it.
11767 * ch-parse.y (seizestatement, visibilty_stmt): Simplify.
11768 * ch-parse.y (grantstatement etc): Don't bother making list.
11769 * ch-lex.l: #include <sys/types.h> before <sys/stat.h>.
11771 Wed Dec 30 16:06:55 1992 Bill Cox (bill@rtl.cygnus.com)
11773 * ch-parse.y, ch-expr.c: add support for declaring & assigning
11775 * ch-typeck.c: allow VARYING structures in assign_type_to_expr.
11777 Tue Dec 29 15:28:48 1992 Bill Cox (bill@cygnus.com)
11779 * ch-actions.c: implement expressions of arrays of char,
11780 ( concatenation, relationals ), correct type of code parameters
11781 * ch-expr.c: correct type of code parameters
11783 Tue Dec 29 11:16:19 1992 Bill Cox (bill@cygnus.com)
11785 * ch-decl.c: cleanup.
11786 * ch-parse.y: put emit_line_note() calls in lotsa places,
11787 per Fred's request; be sure that statements get counted also.
11788 * ch-lex.l: standardize function headers.
11790 Tue Dec 29 10:41:56 1992 Fred Fish (fnf@cygnus.com)
11792 * ch-decl.c (start_chill_function): Always return 1, rather
11793 than a random value.
11794 * ch-lex.l (check_newline): Add a version for chill that
11795 just snarfs the right value for main_input_filename out of
11796 the first line of the input file, without disturbing the
11797 lexer state or requiring it's assistance.
11798 * ch-actions.c (lang_init): Call check_newline, like the
11799 other language frontends, to get main_input_filename set
11800 from first line of input file.
11802 Mon Dec 28 18:49:01 1992 Bill Cox (bill@cygnus.com)
11804 * ch-parse.y: clean up conflicts. The remaining one is
11807 Mon Dec 28 17:28:40 1992 Bill Cox (bill@cygnus.com)
11809 * ch-parse.y, ch-lex.l, ch-actions.c: add stubs for I/O,
11810 clean up some parser conflicts.
11812 Mon Dec 28 15:00:20 1992 Bill Cox (bill@cygnus.com)
11814 * ch-parse.y, ch-lex.l: add keywords and parsing for most of
11817 Sat Dec 26 20:48:23 1992 Fred Fish (fnf@cygnus.com)
11819 * chillrt/chillrt0.c: Oops, SVR4 doesn't need leading '_'
11820 on build_exceptions.
11822 Sat Dec 26 11:00:36 1992 Fred Fish (fnf@cygnus.com)
11824 * ch-grant.c (chill_finish_module_code): Call
11825 assemble_constructor_alias rather than assemble_constructor.
11826 * varasm.c (assemble_constructor_alias): New function,
11827 like assemble_constructor, but also handles the case where
11828 ASM_OUTPUT_CONSTRUCTOR is not defined and GNU ld is not
11829 being used. Emits a symbol table alias name with the correct
11830 prefix for collect to find and add to the __CTOR_LIST__.
11831 * chillrt/chillrt0.c: Build on previous hack that gets
11832 _build_exceptions into the __CTOR_LIST__, to make it work
11833 for both the non GNU-ld case and for the SVR4 case.
11835 Tue Dec 22 18:24:55 1992 Bill Cox (bill@cygnus.com)
11837 * ch-loop.c: clean up location enumeration - one more

11851 ch-loop.c: rough draft of location enumeration
11852 ch-lex.l, ch-expr.c, ch-decl.c: minor cleanup
11853 ch-actions.c: finish making pred() and succ() work.
11855 Mon Dec 21 10:04:35 1992 Bill Cox (bill@cygnus.com)
11857 * ch-actions.c: allow pred(char) and succ(char).
11859 Sun Dec 20 16:04:28 1992 Bill Cox (bill@cygnus.com)
11861 * ch-expr.c, ch-actions.c, ch-parse.y, ch-loop.c,
11862 c-expr.c: make DO WITH work.
11864 Sun Dec 20 12:22:53 1992 Bill Cox (bill@cygnus.com)
11866 * ch-loop.c, ch-actions.c, ch-typeck.c: powerset loops
11869 Sat Dec 19 14:20:23 1992 Per Bothner (bothner@cygnus.com)
11871 * c-typeck.c (process_init_constructor): Add warning if
11872 there is a duplicate default initializer element.
11873 * ch-typeck.c (chill_give_type_to_expr): New function,
11874 to handle coercion of an expression to context-given type,
11875 Takes care of untyped tuples, and case expressions.
11876 * ch-decl.c (do_decls), ch-typeck.c (chill_expand_return,
11877 chill_expand_result), ch-parse.y <assignaction>:
11878 Use chill_give_type_to_expr().
11879 * ch-typeck.c (chill_handle_case_label): New parameter list,
11880 to handle the (new) conventions for <case_label>, including
11881 default elements and ranges.
11882 * ch-parse.y <expanded_case_label>, ch-typeck.c
11883 (expand_case_expr): Use new version of chill_handle_case_label.
11884 * ch-decl.c (push_syndecls): Change parameters: Instead of
11885 TREE_LIST representing a compete <synonym definition statement>,
11886 just pass the parts of a single <synonym definition> as 3
11887 different parameters. Also, use chill_give_type_to_expr(),
11888 to handle untyped tuples in the RHS.
11889 * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct
11890 a tree - just call push_syndecls() on each <synonum_definition>
11892 * ch-parse.y (exprlist_get_single): Remove; no longer needed.
11893 * ch-parse.y: Handle <tuple> without mode name diferently from
11894 <tuple> with mode name. The latter is a <primval> that can be
11895 in most contexts, but if the <mode name> is missing, the <tuple>
11896 is only allowed in certain contexts. Use the new non-terminal
11897 <untyped_expr> to indicate those contexts where untyped tuples
11898 (and case expressions) are valid because the expression gets a
11899 type from its context (such as the RHS of an assignment).
11900 Use chill_give_type_to_expr in those contexts.
11902 Sat Dec 19 14:01:26 1992 Bill Cox (bill@cygnus.com)
11904 * ch-actions.c, ch-loop.c, Makefile.in: looping stuff.
11906 Sat Dec 19 10:16:20 1992 Bill Cox (bill@cygnus.com)
11908 * ch-parse.y: clean up warning messages from byacc. bison
11909 still complains thrice.

11913 * ch-actions.c (maybe_chill_comptypes): Delete unused
11915 (chill_comptypes): Add new parameter ERRSTR. All callers
11917 (build_chill_binary_op): Fix indentation to match GNU coding
11920 Fri Dec 18 08:18:13 1992 Bill Cox (bill@rtl.cygnus.com)
11922 * ch-parse.y, ch-expr.c, ch-actions.c, expr.c: major

11932 a default initializer element.
11933 * ch-parse.y: Implement default elements for tuples
11934 (as in '(else):' and '(*):' ).
11936 * ch-parse.y: Previous change to dis-ambiguate case-labels
11937 seems to have allowed getting rid of all of the expr_or_list hair.
11938 * ch-decl.c (do_decls): Undo Tiemann's change to "Handle
11939 initialization of multiple variables by a tuple" - the
11942 Wed Dec 16 11:17:53 1992 Bill Cox (bill@cygnus.com)
11944 * ch-parse.y: complete re-write of DO statement handling.
11945 now operational, except WITH is stubbed out. Improved
11946 syntax error message.
11947 * ch-actions.c: DO support: high_domain_value(), low_domain_value ().
11948 * ch-expr.c: fixes to IN_EXPR handling.
11950 Tue Dec 15 17:15:13 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11952 * ch-grant.c: Add casts to alloca return to avoid compiler warning.
11953 * ch-lex.c: Likewise.
11955 * Makefile.in (ch-lex.c): Delete incorrect free declaration added
11956 by flex to avoid compiler error.
11958 Tue Dec 15 08:41:08 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11960 * ch-decl.c (do_decls): Handle initialization of multiple
11961 variables by a tuple.
11963 * ch-decl.c (do_decls,start_chill_function): Make DECL public
11964 if we're doing a GRANT ALL at top level.
11966 * ch-lang.c (build_range_type): Deal with typecast to CHAR in
11969 * c-typeck.c (digest_init): SET_TYPE is not a scalar type.
11970 BOOLEAN_TYPE and CHAR_TYPE are scalar types.
11972 Mon Dec 14 14:58:32 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11974 * ch-lex.l (get_chill_{linenumber,filename}): New functions.
11975 (convert_number): Use LONG_TYPE_NODE instead of INTEGER_TYPE_NODE.
11977 Mon Dec 14 13:36:44 1992 Bill Cox (bill@cygnus.com)
11979 * expr.c: install and test newer Pascal IN_EXPR code,
11980 but don't activate it - it's very verbose.
11982 Mon Dec 14 00:22:49 1992 Fred Fish (fnf@cygnus.com)
11984 * Makefile.in (LANGUAGES): Add chill.
11985 * Makefile.in (CHILL_INSTALL_NAME, CHILL_CROSS_NAME):
11986 New macros for chill native and cross installation names.
11987 * Makefile.in (COMPILERS): Add cc1chill.

11991 sublibchill.a, ch-parse.o, ch-parse.c ch-*.o, install-libchill,
11992 install-librmt): New targets.
11993 * Makefile.in (install-native): Add install-libchill,

11998 * ch-actions.c, ch-expr.c: Fix the pop-count in library calls.
12000 Sun Dec 13 14:07:32 1992 Bill Cox (bill@cygnus.com)
12002 * ch-actions.c: fix unary operations, modulus ops,
12003 (discovered after extending regression tests).

12007 * resync with Michael and Wilfried
12009 Sun Dec 13 09:11:25 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
12011 * ch-parse.y (output_constant): Fixed some whitespace
12013 * ch-tree.h: Add declarations for new chill functions that
12014 have been implemented but not (yet) declared.
12016 Sat Dec 12 00:17:23 1992 Per Bothner (bothner@cygnus.com)
12018 * c-typeck.c (process_init_constructor): Warn about duplicate
12019 labels for labelled initializer elements.
12020 * ch-lex.l (various operator tokens, such as "+"): Don't
12021 set yylval.code to a TREE_CODE; this is better done in parser.
12022 * ch-parse.y: Some work with case labels and tuples.
12023 Get literal range as tuple (and case) labels working.
12024 Fix some problems introduced by recent grammar overhaul.
12026 Fri Dec 11 13:28:48 1992 Bill Cox (bill@cygnus.com)
12028 * ch-actions.c, ch-parse.y ch-tree.h ch-expr.c, ch-typeck.c:
12029 got long, real expressions working. We can also call a func-
12030 tion and use its return value.
12032 Thu Dec 10 14:45:17 1992 Per Bothner (bothner@cygnus.com)
12034 * ch-parse.y: Major change to remove or at least identify
12035 parser ambiguities. One result: We now allow actions that
12036 start with '(', as required by teh Blue Book. This does break
12037 some things; look for FIXME for things that need work.
12038 * ch-typeck.c (chill_expand_case_expr): We need an extra
12039 level of looping to (in the future) support <case label
12040 specification>s with more than one <case label list>.

12068 * ch-actions.c (lang_init): Set LINENO to 1 at beginning to
12069 indicate we are done with initialization.
12071 * ch-decl.c (do_decls): Set TREE_PUBLIC if we are doing a
12073 (start_chill_function): Ditto.

12138 (push_newmode,push_synmode): Call `fixup_unknown_type' when we
12139 see a declaration that uses `unknown_type_node'. FIXME.
12141 * ch-grant.c (decode_constant): New function.
12142 (decode_decl): Call `decode_constant' for CONST_DECLs.
12144 * ch-lex.l (char action): Use ridpointers instead of
12145 lookup_name to get "char"'s declaration.
12147 * ch-parse.y: Call `build_lang_decl' instead of `build_decl'
12148 when we need to build a TYPE_DECL.
12150 Tue Dec 2 09:44:05 1992 Bill Cox (bill@cygnus.com)
12152 * ch-typeck.c: clean up a gcc warning with a forward

12160 Tue Dec 1 16:38:51 1992 Fred Fish (fnf@cygnus.com)
12162 * ch-actions.c (lang_init): Ifdef out initializations for
12163 __builtin_abs and __builtin_fabs, since they are duplicates of
12164 initializations in c-decl.c, and trigger spurious warnings.
12166 Tue Dec 1 16:35:18 1992 Bill Cox (bill@cygnus.com)
12168 * ch-parse.y: make size() work with a typename argument.

12197 * chillsh: New script frontend (ala g++), installed as "chill".
12198 Can't be called "chill.sh" because make tries to cat it into the
12199 "chill" directory. Can't be called just "chill" cause that's
12200 already there as a directory.
12201 * Makefile.in: Add rules to install chillsh as "chill".
12202 * chill/libchill.c: Temporarily ifdef out stuff that wants
12203 to conflict with i486/SVR4 runtime or wants to pull in librmt.a,
12204 which itself causes linkage to fail.

12226 * ch-actions.c: removed compile warning, better code for abs.
12228 * ch-parse.y: add productions for builtin functions succ, pred,
12229 abs, and size. Add %tokens also. Sort %tokens alphabetically.

12232 pred, succ, etc. Put flex -a option into Makefile.in, so we can
12233 clean up the lexer soon.

12249 * ch-typeck.c (chill_expand_case_expr): New function.
12250 Placeholder to implement case expressions.
12251 * ch-typeck.c (chill_expand_result, chill_expand_return):
12252 Handle mode-unspecified tuples and case expressions in
12253 the context of RETURN and RESULT actions.
12254 * chill.y (assignaction): Handle case expressions in the
12255 context of the RHS of an assignment action.
12256 * chill.y (caseaction): Remove spurious duplicate OF in grammar.
12257 * chill.y: Handle labeled structure tuples.
12258 * chill.y: New rules to parse CASE expressions.
12259 * tree.c (build_function_types): Allow Chill functions
12260 to return arrays and functions.

12265 tuple (constructor) given an expected (context) type.
12266 * chill.y: Implement 'LHS := TUPLE' using expand_chill_tuple,
12267 using the mode of the LHS and the expected type of the TUPLE.
12268 * chill.y: Implement initialization.
12269 * chill.y: Fix some syntax bugs (forbidlist must be surrounded
12270 by parentheses), and remove or note ambiguities.
12271 * chill.y: Started converting layout style to be like c-parse.in.
12272 * chill.y: Implement IF expressions.
12273 * chill.y: Added syntax rules for tuples. Labelled and unlabelled
12274 array tuples should now work (in some contexts).
12275 * ch-actions.c: Initialize doing_chill_thang to 1.
12276 * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
12277 initializer, to make pushdecl and finish_decl work.
12278 * c-decl.c (convert_for_assignment): If Chill, don't convert
12279 function and arrays into pointers. (Maybe functions should
12280 still be converted?)
12281 * c-typeck.c (grokdeclarator): Allow functions in Chill
