3377 * expr.c (build_chill_repetition_op): Fix repeating all-zero
3378 bitstring with orig_len!=1. Also, call build_boring_bitstring
3379 if original string was all ones, using one range. Also:
3380 Cannot use one-bit TYPE_PRECISION to get bitstring length.
3382 Tue Oct 25 14:11:07 1994 Per Bothner <bothner@kalessin.cygnus.com>
3384 * convert.c (convert): When converting BOOL constant to
3385 bit-string, bit_one_node and bit_zero_node were switched.
3386 * actions.c (chill_expand_assignment): Use force_addr_of,
3387 not build_chill_addr_expr - latter yields bogus error.
3389 Fri Oct 21 14:26:52 1994 Per Bothner <bothner@kalessin.cygnus.com>
3391 * expr.c (build_chill_indirect_ref): Check for POINTER_TYPE (only)
3392 after converting from REFERENCE_TYPE.
3393 * expr.c (build_compare_expr): Convert to common mode *after*
3394 we've checked compatibility.
3396 Fri Oct 21 02:29:15 1994 Wilfried Moser (moser@rtl.cygnus.com)
3398 * lex.l (check_newline): Use getc instead of getlc to read
3399 the filename in a # line name directive to avoid possibly
3400 downcaseing of a filename.

3417 of NUM. NUM delivers the INT derived class.
3419 * grant.c (write_spec_module): Add writing of
3420 <> USE_SEIZE_FILE "x.grt" <>
3421 SEIZE ALL;

3431 * convert.c (convert): Only call digest_array_tuple if ARRAY_TYPE.
3432 * typeck.c (chill_expand_tuple): Print error if type is
3433 neither array, struct, or powerset.
3435 * expr.c (chill_expand_expr cases CONCAT_EXPR, SET_*_EXPR,
3436 UNDEFINED_EXPR): Call preserve_temp_slots for temp targets.
3437 If target is not MEM, make temp (even if not REG) to simplify
3438 - and don't copy original target to temp target first. (Not needed.)
3440 * lang.c (maybe_objc_comptypes): Just return -1.

3470 * expr.c (build_chill_descr): Add missing call to mark_addressable.
3471 * loop.c (toop_loop_end_check): Replace build1 (ADDR_EXPR ...)
3472 with call to force_addr_of (which calls mark_addressable).
3473 * expr.c (build_chill_descr, build_chill_inttime): Likewise.

3512 Wed Sep 21 00:54:21 1994 Per Bothner (bothner@kalessin.cygnus.com)
3514 Give up on trying to use the cleanup mechanism in stmt.c to
3515 make sure the exception handler get unlinked on goto/exit/return.

3579 * lex.l (readstring): Add processing of control sequence
3580 in character string literals. The granting mechanism writes
3581 this to grant files.

3585 * expr.c (compare_records): In case of -fpack do always
3586 a memcmp instead of comparing each field of the

3599 (add_taskstuff_to_list): Add a new argument, which is
3600 the entrypoint of a process.
3601 (build_process_header): Change PROCESS arguments to be
3602 like arguments of a function. There will be a wrapper
3603 which is the real entry point for a PROCESS. This wrapper
3604 is automatically build after a PROCESS definition and gets
3605 as argument a pointer to a structure looking like the
3606 arguments of the PROCESS. This wrapper will call the
3607 PROCESS (see build_process_wrapper).
3608 (build_process_wrapper): New function (see above).
3609 (build_start_process): Change processing of arguments.
3610 (tasking_setup): Add processing of a different entry point

3622 * decl.c (init_decl_processing): Add declaration of memcmp
3623 function.
3625 * ch-tree.h: Add new prototype for build_process_wrapper,
3626 change prototypes for add_taskstuff_to_list and

3638 generated.
3639 * Makefile.in (GNUCHILL_VERSION): Remove it, its defined in
3640 Make-lang.in.
3642 * chill.in: In case of -fgrant-only pass "-S -o /dev/null"
3643 to the compiler to avoid generation of an object file.
3645 Thu Sep 8 12:07:28 1994 Per Bothner (bothner@kalessin.cygnus.com)
3647 * convert.c (display_int_cst), ch-tree.h: New function.
3648 * convert.c (digest_array_tuple): Use digest_int_cst to
3649 provide better error messages. Return error_mark_node on error.
3650 * grant.c (decode_const): Simplify by using digest_int_cst.
3651 * grant.c (format_character, find_assoc): Removed.
3653 * decl.c (do_decl): Add missing TREE_CHAIN.
3655 * decl.c (finish_incomplete_decl): Removed.
3656 (init_decl_processing): Don't set incomplete_decl_finalize_hook.
3657 (finish_decl): Remove old C-specific code to deduce size of
3658 array from initialization.
3659 (complete_array_type): Just make it abort.
3661 * except.c (finish_handler_array): Avoid calling C-specific kludge
3662 complete_array_type.
3664 * convert.c (digest_constructor): Rename, and re-write to:
3665 (digest_array_tuple, convert): No longer use the code in
3666 ../c-typeck.c; use a Chill-only implementation (sigh).
3668 * typeck.c (chill_expand_tuple): Remove unneeded call to
3669 complete_array_type.
3671 * expr.c (fold_set_expr), grant.c (decode_constant),
3672 typeck.c (expand_constant_to_buffer): Update name of called
3673 function unpack_set_constructor to get_set_constructor_bits.
3674 * expr.c (powersetlen ): Remove redundant call to convert.
3676 * ch-tree.h (unpack_set_constructor): Removed obsolete declaration.
3678 * inout.c (build_chill_writetext): Handle 64-bit integer literals
3679 by trying to convert them to a smaller type.
3681 * lex.l (convert_number): Always use long long type (possibly
3682 unsigned) to avoid problems with constant folding truncation.
3684 Mon Sep 5 08:08:22 1994 Wilfried Moser (moser@rtl.cygnus.com)
3686 * ch-tree.h (enum chill_built_in_function): Add BUILT_IN_QUEUE_LENGTH.

3692 * tasking.c (build_queue_length): New function.
3694 * tasking.c (tasking_init): Add new external function definition.
3696 Thu Sep 1 15:38:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3698 * lex.l (default_lex): New function. Progress towards
3699 getting rid of [f]lex.
3701 * lex.l (convert_number): Use mul_double and add_double.
3702 Set result type to a reasonable type in which the literal
3703 will fit. Give error message if literal is too big.
3705 * lex.l (equal_number): Switch (temporarily) to permanent obstack.
3707 * typeck.c (build_chill_slice_with_range): Check for empty
3708 slice *after* we have checked for upper/lower limit in range.

3711 CHAR ranges are represented as INTEGER_TYPEs.)
3713 * tasking.c (build_process_header): Add missing call to
3714 expand_start_bindings.
3715 * parse.c (end_function): Add missing expand_end_bindings.
3717 Wed Aug 31 17:25:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3719 * decl.c (init_decl_processing): Set set_alignment.
3721 Tue Aug 30 16:40:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
3723 * actions.c (print_missing_cases, check_missing_cases,
3724 BITARRAY_TEST, BITARRAY_SET): New functions and macros,
3725 to check for completeness of case actions and expressions.
3726 * decl.c (c_decode_option, init_decl_processing):
3727 Don't set warn_switch.
3728 * expr.c (chill_expand_case_expr): Call check_missing_cases
3729 instead of check_for_full_enumeration_handling.
3730 * parse.c (parse_case_actions): Call check_missing_cases.
3732 * expr.c (build_chill_binary_op): Remove some dead code.
3733 * expr.c (chill_truthvalue_conversion): Call build_chill_binary_op
3734 instead of build_binary_op.
3735 * ch-tree.h (binary_op_error, build_binary_op): Unused. Removed.
3737 * parse.c (end_function): Use kept_level_p in parameter to
3738 poplevel. This reverts a June 13 change.

3751 * tasking.c (build_receive_signal_case_label): Remove backwards
3752 chill_convert_for_assignment (which converted whatever garbage
3753 was in the *target* to the type of the signal argument!).
3755 Fri Aug 19 07:10:43 1994 Wilfried Moser (moser@rtl.cygnus.com)
3757 * inout.c (build_chill_io_list_type, build_enum_tables),
3758 tasking.c (build_tasking_struct): Temporarily reset
3759 maximum_field_alignment to 0, so that the compiler-built
3760 data structures needed by the RTS can be independent of -fpack.
3762 Thu Aug 18 13:39:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3764 * typeck.c (build_init_struct): Temporarily reset
3765 maximum_field_alignment to 0, so that the compiler-built
3766 data structures needed by the RTS can be independent of -fpack.
3768 Wed Aug 17 23:48:33 1994 Wilfried Moser (moser@rtl.cygnus.com)
3770 * parse.c (parse_primval, expect, parse_on_exception_list):
3771 Print error message only in pass 2.
3773 Wed Aug 17 13:47:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3775 * decl.c (switch_to_pass_2): Revert June 13 change,

3778 * ch-tree.def (SLICE_EXPR): New tree-code.
3779 * typeck.c (build_chill_slice): For building a slice of a
3780 bit-string, just generate a SLICE_EXPR.
3781 * decl.c (init_decl_processing): Declare __pscpy.
3782 * actions.c (chill_expand_assignment): Handle a SLICE_EXPR
3783 on the LHS of assignment, by calling __pscpy.
3784 * expr.c (chill_expand_expr): Handle SLICE_EXPR (as a RHS
3785 value) by using __psslice to copy slice to a temp.
3787 Wed Aug 17 05:52:44 1994 Wilfried Moser (moser@rtl.cygnus.com)
3789 * Make-lang.in: Change version of GNUCHILL compiler to 1.4.1.
3790 * expr.c (build_chill_length): Enable LENGTH built-in to process
3791 Buffers and Events too (Z.200/1992).
3792 * lex.l (yywrap): Always set yyin to finput and/or grt_in. On
3793 a linux system the previous version was not able to run.
3794 * tasking.c: Correct processing of infinite buffer- and event-length
3795 to avoid RANGEFAIL warning.
3797 Thu Aug 11 11:46:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3799 * parse.c (parse_if_expression_body): Don't call the C-specific
3800 build_conditional_expr. Just do build_nt (COND_EXPR, ...).
3801 * convert.c (convert): Convert a COND_EXPR by converting
3802 each branch.
3804 * convert.c (convert): Don't call convert before
3805 convert_to_reference. It's apt to do weird and unneedful things.
3806 * convert.c (convert): If the expression is varying, just call
3807 varying_to_slice, which simplifies quite a bit.
3809 * ch-tree.h (varying_to_slice): Add prototype.
3810 * typeck.c (varying_to_slice): Remove prototype.
3812 * satisfy.c (satisfy): Move case PAREN_EXPR from type 'e'
3813 to type '1'.
3815 * except.c (emit_setup_handler): Temporarily reset the
3816 maximum_field_alignment to zero so the compiler's exception
3817 data structures can be compatible with the run-time system,
3818 even when we're compiling with -fpack.
3820 * expr.c (compare_records): Call saved_if_needed on operands.
3822 * expr.c (build_set_expr case NE_EXPR): Don't use __nepowerset
3823 which has been reimplemented to just call __eqpowerset and
3824 invert the result. Inline this new implementation by
3825 handling as EQ_EXPR, and inverting the result.
3826 * decl.c (init_decl_processing): Don't define unused __eqpowerset.
3828 * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
3829 type boolean_type_node, not void_type_node. (Fixing this
3830 avoids a crash in the back-end.)
3832 * grant.c (decode_constant): In a CALL_EXPR, if the argument
3833 list is not a TREE_LIST (as in string repetiation), don't
3834 emit parentheses.
3836 Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3838 * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
3839 CONST_DECL is from a SET definition. (This is safer than
3840 checking that the type is ENUMERAL_TYPE, because synonym
3841 definitions may have a NULL TREE_TYPE.)
3842 Also, if we have duplicate enums whose types are identical,
3843 this is an error.
3844 * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
3845 an extra 'quiet' parameter, which is true if we're called from
3846 bind_sub_modules. (In that case an error message about duplicated
3847 decls would be repeated later, so suppress it.)
3849 * parse.c (stmt_count): Removed, not used.
3850 (INIT_ACTION): Call emit_line_note only if !ignoring.
3851 (parse_begin_end_block): Do INIT_ACTION even if ignoring.
3853 Fri Aug 5 12:39:11 1994 Per Bothner (bothner@kalessin.cygnus.com)
3855 * parse.c (parse_untyped_expr): Add missing semi-colon.
3857 Thu Aug 4 17:40:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
3859 * parse.c (parse_untyped_expr): Fix various problem for the
3860 case that we see a '(': Add missing 'case' keyword.
3861 Only recurse if '(' is followed by 'if', 'case' or '[',
3862 and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
3864 * parse.c (parse_send_action): Remove extra nreverse.
3866 Thu Jul 28 04:00:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3868 * expr.c (build_allocate_global_memory_call, build_allocate_memory_call):
3869 Add new checks.
3871 Tue Jul 26 22:48:15 1994 Michael Tiemann (tiemann@blues.cygnus.com)
3873 * parse.c (parse_untyped_expr): Added missing "case" before LPRN.
3874 Added a missing call to `require' as well.
3876 Tue Jul 19 10:30:12 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3878 * lex.l (yywrap): Define as yywrap_chill to avoid conflicts with
3879 the extern declaration in the flex skeleton.
3881 Mon Jul 18 23:06:04 1994 Per Bothner (bothner@kalessin.cygnus.com)
3883 * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
3884 Check the type of the instance expr using CH_COMPATIBLE,
3885 and not just == instance_type_node. (This allows
3886 the expression to have mode READ INSTANCE).
3887 * tasking.c (build_instance_type): Give instance_type_node
3888 a non-null novelty (i.e. different from a struct).
3889 * tasking.c (build_receive_case_start, build_delay_case_start):
3890 Check that for a location using CH_LOCATION_P.
3892 Mon Jul 18 13:22:23 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
3894 * expr.c (finish_chill_unary_op): Use TREE_SET_CODE not TREE_CODE
3895 to modify a tree code.
3897 Mon Jul 18 11:24:57 1994 Bill Cox (bill@rtl.cygnus.com)
3899 * convert.c (digest_structure_tuple): Fix thinko in TREE_CODE
3900 comparison.
3902 Mon Jul 18 05:40:15 1994 Doug Evans (dje@canuck.cygnus.com)
3904 * decl.c (warn_bad_function_cast): Define so cc1chill will link.
3906 Thu Jul 14 18:37:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3908 * parse.c (parse_send_action): Do tree_cons *before* checking
3909 for end of loop.
3911 Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3913 * convert.c (digest_structure_tuple): Don't use convert to
3914 coerce initial value, use chill_convert_for_assignment instead.
3915 (Thus we also get range_checking.)
3917 * expr.c (build_chill_card): Use force_addr_of instead of
3918 build_chill_addr_expr.
3920 * loop.c (build_temporary_variable): Stylistic tweak.
3921 * loop.c (maybe_make_for_temp): Initialize temp using
3922 explicitly, not using assignment. Avoids a problem if
3923 the expression is read-only.
3924 * typeck.c (smash_dummy_type): Always used the saved TYPE_NAME
3925 and CH_NOVELTY_FLAG.
3927 Wed Jul 6 20:12:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3929 * expr.c, ch-tree.h (finish_chill_unary_op): New function,
3930 based on code ripped out of build_chill_unary_op.
3931 (build_chill_unary_op): Call finish_chill_unary_op unless pass==1.
3932 * satisfy.c (satisfy): Call finish_chill_unary_op when needed.
3934 Mon Jun 27 11:29:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3936 * tree.c (save_if_needed), ch-tree.h: New function.
3937 * typeck.c (build_chill_slice_with_range,
3938 build_chill_slice_with_length): Call save_if_neeed on array arg.
3939 * expr.c (varying_to_slice): Re-write to use save_if_needed.
3941 * typeck.c (extract_constant_from_buffer): Handle BOOLEAN_TYPE.
3943 Mon Jun 27 01:11:10 1994 Wilfried Moser (moser@rtl.cygnus.com)
3945 * inout.c (build_chill_io_list_type): Change layout of __tmp_WIO_list
3946 that it is always the same, regardless if compiled with -fpack
3947 or not.
3949 Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3951 * lex.l (yywrap): Kludge to work around mis-synchronization
3952 between lexer (which read ahead) and parser: Don't emit
3953 (left-over) uze_seizefile directives at the end of file.
3955 * typeck.c (build_chill_array_ref): Allow the derived
3956 array indexing syntax for arrays of bit strings.
3957 Add a comment explaining why.
3959 * typeck.c, ch-tree.h (string_assignment_condition): Change
3960 the interface. Return a boolean expression (which can be
3961 used in a conditional at run-time); never expand anything.
3963 * actions.c (chill_convert_for_assignment): Check
3964 string_assignment_condition here, rather than in callers.
3965 * actions.c (chill_expand_assignment): Don't need to check
3966 string_assignment_condition here.
3967 * expr.c (build_chill_function_call): Likewise.
3968 * satisfy.c (safe_satisfy_decl): Update accordingly.
3969 * decl.c (do_decl): Simplify testing and conversion by
3970 deferring everything to chill_convert_for_assignment.
3972 * parse.c: Combine the two variables 'ignore_exprs' and
3973 'ignore_actions' into one variable called 'ignoring'.
3974 * ch-tree.h: Add 'extern int ignoring'.
3975 * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
3976 Rename ignore_actions and ignore_exprs to ignoring.
3977 Remove unneeded extern declarations.
3978 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3979 build_chill_arrow_expr, build_generalized_call, build_delay_action,
3980 build_buffer_type, build_event_type): I changed my mind. It is
3981 cleaner to check for 'ignoring' in the parser, rather than here.
3982 * parse.c (parse_action, parse_primval, parse_opt_mode):
3983 Therefore we must check for ignoring here.
3984 * parse.c (parse_loc_declaration): Set ignoring in pass 2
3985 when parsing the mode.
3987 * tasking.c (generate_tasking_code_variable): Do arithmetic
3988 on signal_code etc using unsigned rather than signed shorts.
3990 * grant.c (static char* current_grant_modename): Removed.
3991 * grant.c (decode_decl case CONST_DECL): Remove error message.
3993 * Make-lang.in (CHILL_SRCS): Add $(srcdir)/ch/parse.c.
3994 * Makefile.in: Fix dependencies for parse.o.
3995 Remove some duplicate dependencies for $(TREE_H).
3997 Mon Jun 13 14:25:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3999 * typeck.c (build_chill_cast): Allow a value cast between
4000 non-discrete object of the same size, but with a pedwarn.
4001 * typeck.c (bit_string_assignment_condition,
4002 char_string_assignment_condition): Merge near-duplicate functions
4003 and place the code in string_assignment_condition.
4005 * decl.c (parm_flag, declare_parm_level, in_param_level_p):
4006 Removed. Not used.
4007 * decl.c (start_chill_function, finish_chill_function): Make
4008 parameter level have same nesting level as body, as required by Z200.
4009 * decl.c (switch_to_pass_2): Always exit if an error has been found.
4010 * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
4011 generated from GRANT ALL.
4012 * decl.c (lookup_name_for_seizing): Don't seize from
4013 the nesting level of builtins (predefined objects).
4014 * decl.c (lookup_name_for_seizing): Make more robust on error.
4016 * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
4017 be 'RESULT' (or 'result'). This makes it more accessible from gdb.
4018 Also, use do_decl to declare it, so that debugging symbols are
4019 generated. And, re-arrange so that actions that need to
4020 be done both passes (such as push_levels) use the same code.
4022 * parse.c (get_type_of): If ignore_exprs, don't lookup name.
4023 * parse.c (end_function): Fix poplevel params.
4024 * parse.c (expect): Don't read forwards on an error.
4025 * parse.c (parse_field): Don't define two tag_list locals!
4026 * parse.c (parse_pass_1_2): Better error message.
4028 * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
4029 parse_opt_mode, rather than vice versa. If parse_opt_mode
4030 returns NULL_EXPR, then parse_mode gives an error.
4031 Change parse_opt_mode (and any functions it calls) to only
4032 return NULL_TREE if there is no mode (even on ignore_exprs).
4033 (parse_set_mode, parse_structure_mode, parse_procedure_mode):
4034 Never return NULL_EXPR.
4035 * tasking.c (build_buffer_type, build_event_type): Return
4036 void_type_node instead of NULL_EXPR if ignore_exprs is true.
4038 * parse.c (parse_synonym_definition): Call parse_untyped_expr
4039 only if we have a mode.
4040 * parse.c (parse_send_action): Parse list of untyped_expr's,
4041 rather than a list of (typed) expressions.
4042 * parse.c (parse_primval): Emit error if '[' seen without
4043 preceding mode name. (If this is to be allowed, call
4044 parse_untyped_expr instead.)
4046 * parse.c (parse_array_index): Renamed to ...
4047 (parse_index_mode): ... to match Z200 terminology.
4048 Re-write to resolve some of the nastier ambiguities,
4049 and allow things like ' CHAR(10) : CHAR(20) '.
4051 * parse.c (parse_tuple_element): Change interface to return
4052 reversed list, so don't call nreverse.
4053 * parse.c (parse_tuple): No longer nreverse element list here.
4054 * parse.c (parse_opt_element_list): Do nreverse here instead.
4055 * parse.c (parse_case_label_list): Call nreverse at end.
4057 Fri Jun 10 15:36:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
4059 * typeck.c (chill_similar): Remove bogus "else".
4061 Wed Jun 8 00:01:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
4063 * ch-tree.h (TYPE_ARRAY_MAX_SIZE): New macro (and comment)
4064 to make it clearer that we are using TYPE_MAX_VALUE in a special way.
4065 * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
4066 * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
4067 * convert.c (convert): When converting a fixed string/array
4068 to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
4069 of (the type of) the padding.
4070 * convert.c (convert): If the concatenation is non-constant, use
4071 the low-level 'build' to set the type of the result (which is usually
4072 a fixed-size array) rather than depend on build_chill_binary_op
4073 to figure it out (it's unable to simplify the size to a constant).
4075 Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
4077 * lang.c (lang_decode_option): Let -fspecial_UC imply
4078 -fno-ignore-case without requiring it explicitly.
4079 * lang.c (lang_decode_option): Support (experimentally)
4080 the -fpack and -fno-pack flags.
4082 Thu Jun 2 20:49:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4084 * configure: Add support for --program-prefix and --program-suffix.
4086 Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
4088 * convert.c (digest_constructor): Check that initial value
4089 is compatible with element mode before calling convert.
4090 * typeck.c (chill_compatible): A string mode is not compatible
4091 with an untyped constructor.
4092 * decl.c (do_decl): Clean up error messages. Use error_with_decl.
4094 * ch-tree.h: Fix inconsistencies: bool_true_node ->
4095 boolean_true_node, and bool_false_node -> boolean_false_node.
4096 * typeck.c (valid_array_index_): Minor simplification.
4098 Tue May 31 04:33:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
4100 * inout.c (build_chill_writetext): Add correct processing
4101 of POWERSET RANGE (setmode).
4103 * lex.l (same_file): Add searching for file(s) in
4104 seize_path_list.
4106 Fri May 27 14:22:42 1994 Per Bothner (bothner@kalessin.cygnus.com)
4108 * Make-lang.c (CHILL.mostlyclean, CHILL.distdir): Don't list
4109 yacc/bison output files, since the grammer is no longer in yacc.
4110 * config-lang.in (diff_excludes): Likewise.
4112 Thu May 26 16:38:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
4114 * gperf, hash.h, lex.l, parse.h: Rename PROCESS_TYPE token
4115 (in some files spelled PROCESS_TYPE_ to avoid clashes
4116 with the PROCESS_TYPE tree_code) to PROCESS_TYPE_TOKEN.
4118 Thu May 26 02:18:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
4120 * timing.c (build_cycle_start): Change call to __define_timeout.
4121 * decl.c (init_decl_processing): Change definitions of
4122 __define_timeout and __wait_timeout.
4124 Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
4126 Replace yacc-based parser with a recursive-decent parser.
4127 (This may seem backwards, but Chill [like C++] is not a
4128 language that is remotely LALR(1). Using a R-D parser
4129 allows us to use look-ahead and to back-up to resolve the
4130 difficult ambiguities.)
4131 * parse.y: Removed.
4132 * parse.c, parse.h: New files, containing new r-d parser.
4133 * Makefile.in: Update accordingly.
4134 * actions.c (chill_convert_for_assignment): Don't return
4135 NULL_EXPR if ignore_exprs is true. It simplifies the parser
4136 if we consistently reserve NULL_EXPR for a missing expression.
4137 * expr.c (build_chill_function_call): Likewise.
4139 * lex.l: Tweaks for new parser.
4140 * lex.l (prepare_paren_colon, paren_paren_colon_level,
4141 paren_level): Ugly hack no longer needed.
4143 * expr.c (build_chill_function_call): Cleanup.
4144 Call chill_convert_for_assignment to convert IN/INOUT
4145 paramaters on both input and output. For LOC parameters,
4146 give error if actual is a non-referable location.
4147 * actions.c (convert_for_assignment): Add new parameter (a
4148 "place" string used in error messages).
4149 * actions.c (adjust_parm_or_field): Removed.
4150 * actions.c (chill_expand_assignment): Take just a single LHS,
4151 and move support for multiple assignments to ...
4152 (expand_assignment_action): ... here. Some cleaning up.
4153 * timing.c (build_cycle_start): Adjust accordingly.
4154 * actions.c (expand_assignment_to_varying_array): Likewise.
4155 * tasking.c (many places): Ditto.
4156 * ch-tree.h: Fix declarations appropriately.
4158 * parse.c (parse_defining_occurrence_list): Return a single
4159 IDENTIFIER_NODE (instead of a singleton list) in the common
4160 case. Minor complication to save a minor amount of space.
4161 * decl.c (do_based_decls): Move guts of code into ...
4162 (do_based_decl): ... this new function.
4163 * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
4164 * decl.c (push_syndecl): Replace by ...
4165 (push_syndecl): ... (which only supports a single name).
4166 (push_modedef): Only handle a single name.
4167 * tasking.c (build_process_header, build_signal_struct_type):
4168 Adjust accordingly.
4170 * expr.c (build_generalized_call): Handle string repetition.
4171 * expr.c (build_chill_repetition_op): Change interface.
4172 * grant.c (decode_constant): Allow parameter list to be
4173 a non-TREE_LIST. (Used for string repetition.)
4175 Wed May 25 11:28:48 1994 Per Bothner (bothner@kalessin.cygnus.com)
4177 * lex.l (make_identifier): Replaced by ...
4178 (read_identifier, handle_name): ... new functions.
4179 * lex.l: Parse an identifiers using read_identifier using
4180 read_identifier and handle_name, rather than having [f]lex
4181 do it. (One reason is that lex uses a fixed-size buffer.)
4183 * lex.l (read_directive, skip_directive): New functions.
4184 Use them to parse compiler-directives, instead of rather
4185 ugly and useless use of lexer start conditions.
4187 Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4189 * decl.c (unnamed_module_number): Renamed to ...
4190 (module_number): .. and make non-static.
4191 (push_module): Always increment module_number.
4192 * lex.l (yywrap): Print warning if no modules seen.
4194 * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
4195 decl to current_seizefile_name (which is unreliable).
4196 * grant.c (chill_grant): Set it here instead.
4198 * expr.c (fold_set_expr): Use int_size_in_bytes instead of
4199 TYPE_PRECISION (which is not defined for a SET_TYPE).
4201 Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
4203 Cleanup to remove need for variables in common storage.
4204 * decl.c: Remove unused use of current_obstack.
4205 * actions.c (maybe_chill_check_decl): Remove unused function.
4206 * actions.h, lang.c: Remove uses of doing_chill_thang.
4207 * ch-tree.h (void_list_node): Make extern (rather than common).
4208 * decl.c (void_list_node): Add definition.
4210 Thu May 19 06:54:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
4212 * configure (build): Build canon_host and canon_target
4213 to pass it to all subsequently generated Makefiles (needed
4214 for testsuite/execute in case of cross build).
4216 Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4218 * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
4219 the input type, which loses with the no-longer-new 2-pass
4220 implementation, since the input "type" could be an IDENTIFIER_NODE.
4221 * grant.c (raw_decode_mode): Rename to decode_mode.
4223 Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
4225 * typeck.c (chill_location): Neither a STRING_CST nor a
4226 CONSTRUCTOR is a location.
4227 * typeck.c (chill_root_mode): Convert a function to a
4228 pointer-to-function.
4229 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
4230 build_chill_arrow_expr): If ignore_exprs, return operand
4231 rather than NULL_EXPR. This makes it easier for the parser to
4232 distinguish missing expressions.
4233 * expr.c (build_max_min): Convert the lower bound of a
4234 set to a long before calling run-time routine.
4235 * expr.c (build_chill_pred_or_succ): Use discrete_type_p
4236 to check the argument type.
4237 * expr.c (build_chill_arrow_expr): If argument is not a location,
4238 do a predwarn if it is a STRING_CST or has function type.
4240 Tue May 17 06:05:13 1994 Wilfried Moser (moser@rtl.cygnus.com)
4242 * configure (build): Remove building of canon_host and canon_target.
4243 It doesn't work in any case.
4245 Mon May 16 02:10:35 1994 Wilfried Moser (moser@rtl.cygnus.com)
4247 * configure (build): Build canon_host and canon_target
4248 to pass it to all subsequently generated Makefiles (needed
4249 for testsuite/execute in case of cross build).
4250 * Make-lang.in (chill-runtime): Change chill to CHILL in the case
4251 statement to build chill-runtime automatically.
4253 Mon May 9 15:30:08 1994 Doug Evans (dje@canuck.cygnus.com)
4255 * Makefile.in (FLAGS_TO_PASS): Define.
4256 (OBJDEPS): Define.
4257 (../cc1chill): Depend on $(OBJDEPS) $(C_OBJS).
4258 * Make-lang.in (cc1chill): Delete dependency on $(OBJS) $(BC_OBJS).
4259 (CHILL.mostlyclean): Use `mostlyclean' as recursive target.
4261 Sun May 8 13:05:00 1994 Per Bothner (bothner@cygnus.com)
4263 * Make-lang.in (cc1chill): Should not depend on libgcc.a.
4265 Thu May 5 18:58:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
4267 * decl.c (copy_lang_decl): New (dummy) function.
4269 Mon May 2 14:33:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
4271 * parse.y (sendaction): Fix thinko (in sense of condition).
4272 * tasking.c (build_receive_case_label): Another thinko.
4274 * parse.y (optsigdest): Force ignore_exprs to 0 while parsing
4275 the (signal-)name.
4277 * decl.c (build_chill_function_type): Don't call layout_type
4278 (since that may prevent parameter or result types being
4279 properly satisfied).
4280 * satisfy.c (satisfy): Layout FUNCTION_TYPEs.
4281 * parse.y (procmode): Call build_chill_pointer_type, rather
4282 than build_pointer_type (which incorrectly sets TYPE_SIZE).
4284 * parse.y (get_type_of): Handle TYPE_DECL (again).
4285 * parse.y (optresultspec): Call build_chill_reference_type, rather
4286 than build_reference_type (which incorrectly sets TYPE_SIZE).
4287 * parse.y (range_or_mode): Rename to plain range, since it
4288 no longer matches modename.
4289 * actions.c (chill_handle_case_label_range): New function, with
4290 functionality moved out of chill_handle_case_label.
4291 * actions.c (chill_handle_case_label): Handle here the case that
4292 the label_value is a TYPE_DECL (modename). Also clean up some.
4293 * typeck.c (build_chill_slice_with_length): Convert max_index
4294 to the type of min_value. (Old code broke on varying strings.)

4305 * lex.h, lex.c: Remove lastiddecl.
4306 * lex.l (name_type_signal): Simplify. We no longer check for

4333 * parse.y (ioindexmode): Removed; use index_mode instead.
4334 * expr.c (build_generalized_call): If args is a RANGE_EXPR,
4335 we have either a slice or a range mode, depending on func.

4337 or a range mode.
4338 * parse.y (call): A slice with both end points can be a range
4339 mode, so defer handling to build_generalized_call (or index_mode).
4341 * typeck.c (build_chill_slice_with_length): Fix type-checking.
4342 * typeck.c (chill_novelty): Undo (part of) change of April 28:
4343 The novelty of a range mode is the novlety of the parent.
4344 * typeck.c (chill_root_mode): Don't return integer_type_node
4345 if argument has non-nil novelty.
4347 * decl.c (global_bindings_p): Return -1 as true, for the sake

4350 Fri Apr 29 13:42:43 1994 Per Bothner (bothner@kalessin.cygnus.com)
4352 * parse.y: Remove TYPENAME and modename. These are now plain
4353 NAMEs. Modify parsing actions appropriately.
4354 * expr.c (build_generalized_call): Handle the case that
4355 TREE_CODE (func) == TYPE_DECL (as in a cast).
4356 * lex.l (name_type_signal): Never return TYPENAME.

4406 * typeck.c (smash_dummy_type): Handle the special case of a
4407 NEWMODE of a range mode, as required by Z200, by creating a
4408 new parent mode with the new novelty (and casting the min
4409 and max of the range to teh new parent mode).

4748 string assignment case.
4749 * expr.c (chill_expand_expr): Now that we're using build_chill_function_call,

4760 * satisfy.c (safe_satisfy_decl): Add range-check for a SYN's value.
4762 Mon Mar 21 13:29:23 1994 Per Bothner (bothner@kalessin.cygnus.com)
4764 * typeck.c (layout_chill_range_type): Instead of tree_int_cst_lt
4765 use compare_int_csts (which is more robust when signedness differs).
4766 Also, convert the bounds *after* doing range checking.
4768 * ch-tree.def (SET_IN_EXPR): New.
4769 * expr.c (chill_expand_expr): Code to expand SET_IN_EXPR,
4770 moved from expand_expr in ../expr.c. Also add some extra

4793 Generate a compile-time message if possible.
4794 (build_compare_expr): Comment out compatibility test - should
4795 not be needed in here. Fix a couple of typos. Add some types
4796 to some build calls.
4798 Sun Mar 20 11:48:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
4800 * decl.c (init_decl_processing): Clean up parameter type
4801 list for __setbitpowerset,
4803 * typeck.c (chill_compatible_classes): Allow the M-reference
4804 to be compatible with the N-value class, with suitable M and N.
4805 * typeck.c (build_chill_slice): Don't smash a void TREE_TYPE.
4806 (We don't need to, and it causes confusion.)
4808 * expr.c (build_compare_expr): Fix thinko. Add save_exprs.
4810 * expr.c (build_compare_expr): Fix a transcription bug
4811 (for converting NULL INSTANCEs). Also #include convert.h.

4814 Works even if their types have different TREE_UNSIGNED.
4815 * expr.c (finish_chill_binary_op): Moved code dealing with
4816 the comparison operators from here ...
4817 * expr.c (build_compare_expr): ... to new function here.
4818 Also, for discrete types, tries to Do The Right Thing, even for
4819 differing values of TYPE_PRECISION and TREE_UNSIGNED.
4820 the code from lay
4821 * ch-tree.h: Declare new functions.
4822 * typeck.c (valid_array_index_p): Various cleanups,
4823 including using new build_parse_expr.
4824 * parse.y: Use new build_compare_expr.
4826 * inout.c (build_chill_writetext): Handle REFERENCE_TYPE args.

4831 Call build_chill_array_ref to get index checking.
4832 (chill_convert_for_assignment): Delete unused errstr
4833 variable.
4834 (chill_expand_assignment): Call build_chill_array_ref
4835 to get runtime index checking.

4842 to have consistent operand types.
4843 * typeck.c (valid_array_index_p): Change interface to pass
4844 validity conditions back on caller's TREE_LIST. We
4845 cannot link the conditions to anything which a
4846 layout_type routine will expand, since that will occur
4847 before the exception handler is set up.
4848 Change calls to valid_array_index_p also.
4850 Fri Mar 18 14:40:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
4852 * actions.c, except.c, loop.c, tasking.c: Call
4853 build_chill_function_call instead of the C-specific

4856 * loop.c (top_loop_end_check): Coerce library function arg.
4857 * convert.c, expr.c: Re-write to avoid calls to C-specific
4858 function build_unary_op (e.g. by calling build1 directly).
4860 * typeck.c (chill_equivalent): Change to force failure
4861 for non-matching integral types (even if not ranges).
4863 * typeck.c, ch-tree.h (build_chill_slice): Make non-static.
4864 * expr.c (varying_to_slice): Call build_chill_slice (and not
4865 build_chill_slice_with_length, which does bunches of range
4866 checking and does not allow the length to be zero).
4867 * convert.c (convert): Fix off-by-one error.
4868 * actions.c (chill_expand_array_assignment): Minor cleaning up.
4870 Fri Mar 18 00:12:48 1994 Per Bothner (bothner@deneb.cygnus.com)
4872 * decl.c (init_decl_processing): __lepowerset and __ltpowerset
4873 take *two* pointer parameters, not one.
4874 * satisfy.c (satisfy): Only call the appropriate layout routine
4875 if TYPE_SIZE is 0 (i.e. type hasn't already been laid out).
4876 * typeck.c (build_chill_slice_with_length): Fix Bill's previous fix.
4878 Thu Mar 17 17:29:43 1994 Bill Cox (bill@rtl.cygnus.com)
4880 * expr.c (build_chill_function_call): Give function call the correct
4881 type tree.
4882 * typeck.c (build_chill_slice_with_length): Restore dynamic range
4883 checking, so it doesn't obscure the CONSTANTness of the length.
4885 Wed Mar 16 17:23:31 1994 Per Bothner (bothner@kalessin.cygnus.com)
4887 * typeck.c (build_chill_slice), expr.c (chill_expand_expr
4888 [case CONCAT_EXPR]): Remove kludge setting slice size upper bound
4889 in TYPE_LANG_SPECIFIC, and restore kludge setting it in MAX_VALUE.
4890 * typeck.c (build_chill_slice): Use TYPE_MAX_VALUE of
4891 array_type if needed for size upper bound of slice_type.
4892 * expr.c (build_concat_expr): Improve calculation of size upper bound.
4894 * typeck.c (valid_array_index_p): Check compatibility using
4895 correct types.
4896 * typeck.c (build_chill_slice_with_length); For now revert
4897 calling valid_array_index_p on length. (It makes it harder
4898 to realize when the slice is constant length.)
4899 * expr.c (build_chill_indirect_expr): Minor tweak. (This
4900 seems to work around a weird C compiler bug. ??)
4902 * expr.c (build_chill_function_call): Cleanup so it doesn't
4903 call build_function_call (in c-typeck.c).
4904 * typeck.c, expr.c: Use build_chill_function_call instead of
4905 build_function_call (in c-typeck.c).
4907 * parse.y (discrete_mode): Move some of the rules from
4908 non_array_mode into new non-terminal.
4909 (arrayindex): Use discrete_mode (with NAME and TYPENAME) to
4910 avoid some misparses.
4911 * ch-tree.h (SLICE_PTR, SLICE_LENGTH): Removed; unused.
4912 * convert.c (digest_structure_tuple): Add missing parameter.
4913 * decl.c (comptypes): Remove unused prototype.
4914 * decl.c (build_chill_function_type): Handle NULL return_type
4915 correctly (convert to void_type_node).
4916 * decl.c (init_decl_processing): layout boolean_type_node *after*
4917 we've set it's TYPE_MIN_VALUE and TYPE_MAX_VALUE.
4919 Wed Mar 16 16:08:22 1994 Bill Cox (bill@rtl.cygnus.com)

4922 * convert.c (convert): Correct calculation of padding length.
4923 * decl.c (grok_chill_fixedfields): Move ignore_exprs test to
4924 parse.y where it belongs. This permits the removal of a kludge
4925 in make_process_struct.
4926 * lex.l, parse.y: Call to_global_level for several errors. Add
4927 code to output error in only one pass.

4929 March 8.
4930 (build_receive_case_end): Add Wilfried's check for errors.

4937 rather than validate_varying_array_ref.
4938 * ch-tree.h: Fix prototype for valid_array_index_p.
4939 * expr.c (chill_expand_expr): Call build_chill_array_ref to get
4940 index validation.
4941 (build_hill_lower, build_chill_upper): Return value now inherits
4942 the novelty of the input parameter.
4943 (varying_to_slice): Use CH_NOVELTY macro rather than calling
4944 chill_novelty directly.
4945 * grant.c (newstring): Make len unsigned and cast xmalloc parameter
4946 to unsigned.
4947 (print_integer_type): Pass string value as APPEND's second parameter.
4948 (decode_decl): Pass a boolean expression as print_proc_tail's
4949 first parameter.
4950 (chill_finish_module_code): Make xmalloc's parameter unsigned.
4951 * lex.l: Pass sizes to xmalloc as unsigned ints. Pass second
4952 parameter to in_word_set as unsigned.
4953 * loop.c (build_loop_start): Check top_loop_end_check return value.
4954 * parse.y: Add casts to int for third do_decls parameter, fifth
4955 build_loop_iterator parameter, etc.
4956 * tasking.c (build_receive_case_end): Chack cond_stack before popping.
4957 * typeck.c (validate_varying_array_ref, chill_max_vary_array_index,

4960 array index is checked.
4961 (build_chill_slice): Restore old functionality where varying_to_slice
4962 is called to handle slices of varying arrays, rather than handling
4963 handling them here.
4964 (build_chill_slice_with_range, build_chill_slice_with_length):
4965 Check range limits for TREE_CONST before calling tree_int_cst_lt.
4966 Delete now-obsolete checks of constant indices.
4968 Mon Mar 14 17:26:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4970 * parse.y (modeless_expr): New rule to allow ([...]) and (if...)
4971 to count as untyped_exprs. (This is not really permitted by the
4972 Blue Book, but has been requested by customers.)
4974 Thu Mar 10 10:11:02 1994 Bill Cox (bill@rtl.cygnus.com)
4976 * chill.texi: Document new command-line options.
4977 * expr.c (build_chill_num): Set unsigned parameter for
4978 type_for_size call correctly (unsigned for enums).

4981 * lex.l: Eat more whitespace.
4983 Thu Mar 10 09:41:37 1994 Bill Cox (bill@rtl.cygnus.com)
4985 * Makefile.in: Have rules to make parse.h, y.tab.c and other
4986 derived files. This allows the gcc/configure list of CHILL
4987 files machinery to work.
4988 * ch-tree.h (permanent_allocation): Add a parameter flag.
4989 * decl.c (finish_chill_function, finish_decl): Provide the
4990 new permanent_allocation flag.
4991 (poplevel): Return early, avoid a seg fault.
4992 * lex.l (NORMAL): Replace this whole state with the predefined
4993 INITIAL state. Force compilation state to global level after
4994 compiler directive error - prevents endless loop on error.
4995 (handle_use_seizefile_directive): Rewrite for readability.
4996 (chill_same_grant_file): Reindent.
4997 Generally handle whitespace differently.
4998 * regression.prpt: Print ten PR numbers per line. The report's
4999 getting too long.
5001 Wed Mar 9 09:58:51 1994 Bill Cox (bill@rtl.cygnus.com)
5003 * decl.c (do_decl): Suppress the string-assignment-condition
5004 error - it was too often seen.
5005 * expr.c (expand_chill_expr): In CONCAT_EXPR, when argument has a
5006 runtime-changing length (as in a slice), get the parent array's
5007 allocation size from its type tree.
5008 * typeck.c (build_chill_slice): Support VARYING arrays. Pass
5009 parent array's static allocation size along in the slice type.

5017 * expr.c (build_chill_sizeof): Fix typo in error msg, add
5018 some whitespace.
5019 * lex.l (name_type_signal): Add debug output.
5020 * parse.y (call): Allow EVENTNAME and BUFFERNAME parameters
5021 to a call, so that SIZE () works on them.
5022 * tasking.c (make_process_struct): Force ignore_exprs non-zero
5023 when processing a SEIZEd PROCESS declaration. This prevents
5024 grox-fixed_fields from returning a NULL, and indirectly protects
5025 the chill_integer_type_node tree from corruption.
5027 Mon Mar 7 19:14:05 1994 Bill Cox (bill@rtl.cygnus.com)
5029 * Makefile.in: Use the 'all' target to build the runtime
5030 library and chillrt0.o.

5033 chill.regress.cron: Move to utils subdirectory.
5034 * expr.c (build_chill_function_call): Mark the INOUT
5035 temporary so it doesn't get optimized into a
5036 register. Fixes the execute/inout.ch bug.
5037 * typeck.c (layout_chill_range_type): Restrict it
5038 from complaining about an empty string type's
5039 bounds (0:-1).
5041 Mon Mar 7 09:06:39 1994 Bill Cox (bill@rtl.cygnus.com)
5043 * Makefile.in (compiler): Restore this target.
5044 (OBJS, BC_OBJS): Delete unused variables.
5045 Add $(FLAGS_TO_PASS) to sub-make invocations.
5046 * ch_decomment.l, ch_makedepend, chill.patches, printf.c,

5051 * except.c (finish_handler_array): When computing address of
5052 the array ex_decl, don't call build_array_ref.

5073 * inout.c (build_chill_writetext): Add handling of a REAL.
5074 * lex.l (INITIAL): Remove all code to discard 'header lines'.
5075 no longer needed.
5076 * parse.y (optheader): Remove - it's obsolete, as is the
5077 HEADEREL token definition.
5079 Fri Mar 4 09:41:18 1994 Bill Cox (bill@rtl.cygnus.com)
5081 * addtest: Fix suffix removal when suffix is .c186.
5082 * regression.sh: Allow for underscores on PR filenames.
5083 * typeck.c: Check in the rewrite mentioned earlier.

5167 since we don't need it until we're testing.
5168 * addtest: Strip suffix from each input filename.
5169 * decl.c (do_decl): Correct error checking. Call
5170 string_assignment_condition for some of it.

5176 name for correctness.
5178 Wed Feb 23 15:07:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
5180 New cleaner solution to the following problem:
5181 Chill allows an action to be followed by an ON-handler.
5182 But we don't know if an action has a handler until we've parsed
5183 its end, yet we want to generate extra code to set up an
5184 exception handling contour only if needed. The old solution
5185 would generate code for the action into an rtl sequence, and then
5186 splice in the exception-setup code if we later found we needed it.
5187 This has a few problems (for example it confuses the management
5188 of stack temporaries), and is ugly. Now that the compiler is 2-pass
5189 we have a cleaner solution: In pass 1, we remember which actions
5190 were followed by ON-handlers. In pass 2, we use this information
5191 to generate appropriate code before an action.
5192 * except.c (push_handler, pop_handler): In pass 1, set up data
5193 structures (global_handler_list) to remember if an action has an
5194 ON-handler. In pass 2, digest this information, and setup
5195 handler if needed.
5196 * except.c, actions.h (pop_handler): Take an extra int arg.
5197 * except.c (emit_setup_handler): New function, with code (moved
5198 from chill_start_on) to emit code before an action that has a handler.
5199 * except.c (except_init_pass_2): New function.
5200 * parse.y (pass1_2): Call except_init_pass_2 before pass 2.
5201 * parse.y (POP_UNUSED_ON_CONTEXT): Don't call pop_sequence.

5203 in pass 1 as well as pass 2.
5204 * parse.y (BEGIN ... END): Re-arrange logic to avoid block_stack
5205 (local to ../stmt.c) getting out of sync.
5206 * actions.c (push_action): Don't need to emit a NOP,
5207 now that we're no longer moving sequences around.
5208 * actions.c (push_action): Call push_handler even in pass one.

5827 on constructor_stack, to allow for nested initializers.
5828 * ch-convert.c (digest_constructor): If we need a varying
5829 array, and have a constructor (for the array elements),
5830 make sure to use convert so that the constructor gets
5831 wrapped in an implicit record constructor.
5832 * ch-decl.c (do_decl): If there is no initializer for a
5833 varying array (or bitstring), create default constructor.
5835 * ch-expr.c (build_chill_lower): Fix thinko for ARRAY_TYPE.

5843 instead of build_chill_array_ref where appropriate.
5844 * ch-actions.c, ch-expr.c, ch-typeck.c: Make operand 1 of a
5845 VARY_ARRAY_REF is a single index, not an index list.
5847 * ch-grant.c (__init_list): Renamed to _ch_init_list, to
5848 avoid a conflict on the Alpha.
5850 Wed Jan 12 10:19:35 1994 Bill Cox (bill@rtl.cygnus.com)
5852 * ch-lex.l (WS): Add BS, VT and CR to definition of

5874 to work around a bug in /usr/ucb/cc on SunOS4.
5876 Mon Jan 10 18:29:36 1994 Bill Cox (bill@rtl.cygnus.com)
5878 * ch-actions.c (chill_convert_for_assignment): Avoid seg fault.
5879 * ch-expr.c (expand_packed_set): Add new parameter to pass
5880 set's minimum ordinal value. Fix loop invariant problem.
5881 (fold_set_expr): Change to add new parameter to
5882 expand_packed_set call.

5899 Also, fix some bugs for bitstrings (with ranges).
5901 (Patches from Tiemann.)
5902 * ch-convert.c (convert1): New function to force TREE_TYPE.
5903 (convert): Use convert1 where appropriate.
5904 * ch-typeck.c: Formatting change.
5905 * ch-parse.y (build_chill_constructor): Fix thinko.
5907 * ch-expr.c (varying_to_slice): If array is not referable,
5908 call save_expr on it, rather than stabilize_reference.
5909 * ch-satisfy.c (safe_satify_decl, for CONST_DECL):
5910 Don't force value to value class if mode is not explicitly
5911 specified. Also, make sure convert etc is only done once.
5913 Sat Jan 8 16:37:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
5915 * ch-decl.c (build_chill_function_type): Don't call
5916 build_function_type, because it does hash canonicalization,
5917 which once in a while looses badly.
5918 * tree.c (build_function_type): Remove no-longer-needed test
5919 for doing_chill_thang.
5921 * ch-tree.h (CH_DERIVED_FLAG): New flag.

5936 * ch-expr.c (finish_chill_binary_op): Use convert_to_class.
5937 * ch-satisfy.c (safe_satisfy_decl): For CONST_DECL, make sure
5938 DECL_INITIAL gets set to result of convert.
5939 Also, clear CH_DERIVED_FLAG for SYN value.
5940 * expr.c (store_constructor): If a [power]set is exactly one
5941 word long, use single-word move.
5943 Sat Jan 8 08:38:29 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5945 * c-typeck.c (chill_initializer_constant_valid_p): Fix typo.
5947 Wed Jan 5 05:18:46 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5949 * ch-typeck.c (build_chill_slice_with_length): Test that ARRAY is of
5950 ARRAY_TYPE before assuming so. Also, subtract 1 from LENGTH in
5951 computation of SLICE_END.
5953 * ch-typeck.c (chill_location): Treat CONSTRUCTORs like STRING_CSTs.
5955 * ch-expr.c (build_chill_indirect_ref): Handle MODE == NULL_TREE.
5957 * ch-expr.c (fold_set_expr): Handle OP1 == NULL_TREE (which happens
5958 for unary set operations).
5960 * ch-expr.c (build_chill_array_expr): Take new argument FORCE. All
5961 callers changed. All callers changed.
5963 * ch-convert.c (digest_structure_tuple): Handle SELECTED_VARIANT
5964 being NULL_TREE until we've started walking the list of values via
5965 the loop over VARIANTs.
5967 * ch-parse.y (build_chill_constructor): If we see an IDENTIFIER_NODE,
5968 treat it as an enum value (and hence constant). Also, only set
5969 TREE_STATIC if the constructor is indeed constant.
5970 * c-typeck.c (chill_initializer_constant_valid_p): If we see a
5971 VAR_DECL, test the TREE_CONSTANT field of the DECL_INITIAL, don't
5972 recurse on the DECL_INITIAL.
5974 Wed Jan 5 01:24:50 1994 Bill Cox (bill@cygnus.com)
5976 * Makefile.in: Add CHILL to LANGUAGES variable.
5977 * ch-actions.c (check_range): Call build_binary_op instead of
5978 fold, build to get the common types chosen.
5979 (cond_range_exception, cond_overflow_exception,
5980 cond_type_range_exception): Delete, obsolete.
5981 (chill_convert_for_assignment): Enable this, get particular
5982 about when to generate rangecheck code.

5984 perform chill_convert_for_assignment on actual parameters.
5985 (build_chill_addr_expr): Correct compiler warning.
5986 * ch-loop.c (build_chill_iterator): Add runtime check for
5987 negative loop step expression.
5988 * ch-tree.h: Add prototype.
5989 * ch-typeck.c (chill_max_vary_array_ref): Correct misunderstanding.
5990 A varying array's length field counts the NUMBER of active array
5991 array entries, not the byte-length of them.
5993 Tue Jan 4 17:57:39 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5995 * ch-decl.c (do_decl): Call `suspend_momenary' if the
5996 converted constructor must live on the permanent_obstack.
5997 * ch-convert.c (convert): When building a new SET_TYPE
5998 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5999 * c-typeck.c (chill_initializer_constant_valid_p): Handle VAR_DECLs.
6001 * ch-typeck.c (chill_location): CONSTRUCTORS that are static

6004 on permanent_obstack if necessary.
6006 * ch-convert.c (digest_structure_tuple): When building a new SET_TYPE
6007 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.

6010 the patch below helped to mess up.
6012 * ch-expr.c (build_chill_arrow_expr): Call `mark_addressable'.
6013 (build_chill_addr_expr): Take new argument ERRORMSG.
6014 All callers changed. Also, call `build_chill_addr_expr' where
6015 we used to call `build1 (ADDR_EXPR, ptr_type_node, ...)' since
6016 that now calls `mark_addressable' automagically.
6018 * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.
6019 This is needed because variables may appear in initialization
6020 statements, and their DECL_INITIALs are their values at
6021 initialization time.
6022 * ch-convert.c (digest_structure_tuple,digest_constructor): Changed
6023 to handle VAR_DECLs as initializers.
6025 * ch-convert.c (digest_structure_tuple): Copy elements of INITS so
6026 they aren't destroyed for later use.

6031 parameter for varying_array_ref calculations.
6032 (build_chill_indirect_ref): Prevent seg fault due to syntax error.
6033 * ch-typeck.c (build_chill_slice_with_range): Correct issuance
6034 of bogus error in votrics.
6035 (build_chill_slice_with_length): Change for debug tracability.
6037 Tue Jan 4 02:43:37 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6039 * ch-convert.c (digest_structure_tuple): Fix phasing problem in
6040 handling variant record initializers.
6041 (various places): Change `pop_init_level' calls to match
6042 `push_init_level' wrt implicit variable.
6044 * ch-typeck.c (build_chill_slice): Convert the dynamic max index to
6045 `integer_type_node' before using it in comparisons. FIXME: should
6046 this be done in `chill_max_vary_array_index' by default?
6048 Tue Jan 4 00:24:14 1994 Bill Cox (bill@cygnus.com)
6050 * ch-actions.c: Fix comments.
6051 * ch-parse.y: Define caseaction_flag.
6052 (caseaction): Create new caseaction_flag node at the start,
6053 then free it at the end. Check it before the ELSE code.
6054 (expanded_case_label): Check the flag here. If set in either
6055 place, generate a jump to the end of the case.
6056 * ch-typeck.c (build_chill_slice_with_length,
6057 build_chill_slice_with_range): Add lots of compile-time
6058 parameter range checking.
6060 Mon Jan 3 21:49:04 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6062 * ch-convert.c (digest_structure_tuple): Call `push_init_level' with
6063 implicit==0 everywhere, not 1.
6064 (digest_constructor): Ditto.
6066 * ch-actions.c (check_range): Permit limits to be NULL_TREE.
6067 Also, hack out some dead code.
6068 * ch-typeck.c (build_chill_slice): Check varying and non-varying
6069 slice constructs for range failures.
6070 (build_chill_slice_with_range): Reindented, but not changed.
6072 * ch-typeck.c (chill_max_vary_array_index): New function.
6073 * ch-expr.c (chill_expand_expr): Call it.
6075 * ch-decl.c (var_data_id, var_length_id): New variables.
6076 (init_decl_processing): Initialize them. All calls to
6077 get_identifier (VAR_LENGTH or VAR_DATA) are now replaced
6078 by references to these variables. This simplifies the code
6079 w/o obscuring anything.
6081 Mon Jan 3 21:24:44 1994 Bill Cox (bill@cygnus.com)
6083 * c-typeck.c: Fix comment.
6084 * ch-actions.c (chill_expand_assignment): Error assigning to
6085 READONLY location. (PR_3903) Pass filename, linenumber
6086 to setbitpowerset runtime routine.
6087 * ch-decl.c (init_decl_processing): Add filename, linenumber
6088 parameters to setbitpowerset prototype.
6089 * ch-expr.c (build_chill_function_call): Error when passing a
6090 READonly location as a LOC or INOUT parameter.
6091 * ch-parse.y (mode): Correct code marking type as readonly.
6093 Mon Jan 3 19:03:55 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6095 * ch-actions.c (chill_expand_assignment): Disable code that defeats
6096 building varying array references.
6097 * ch-expr.c (chill_expand_expr): Add rangecheck code to
6098 VARY_ARRAY_REF case.
6099 * ch-typeck.c (build_chill_array_ref): Don't call an `expand_'
6100 function (in this case, `validate_varying_array_ref') when we're
6101 doing a `build_' operation.
6103 * ch-typeck.c (validate_varying_array_ref): Simplify interface
6104 since INDEX parameter can never meaningfully be an INDEXLIST.
6105 * ch-actions.c (expand_varying_length_assignment): Caller changed.
6107 Mon Jan 3 07:29:45 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6109 * ch-typeck.c (build_chill_cast): Set TREE_CONSTANT on NOP_EXPRs.
6110 * ch-convert.c (digest_structure_tuple): Switch to permanent_obstack
6111 if we need to build a CONSTRUCTOR for a SET_TYPE initializer.
6112 (digest_structure_tuple): If TREE_VALUE (VALUE) == NULL_TREE, don't
6113 call CH_COMPATIBLE or try to convert it to TREE_TYPE (FIELD). This
6114 can happen when constructors are output incrementally.
6115 * c-typeck.c (initializer_constant_valid_p): Handle SET_TYPEs.
6116 * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
6117 CONSTRUCTORS.
6119 Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6121 * ch-convert (digest_structure_tuple): Handle SET_TYPEs. Also, call
6122 `convert' so we can handle INSTANCE types (and other anomolies)
6123 correctly.
6125 * ch-convert.c (digest_structure_tuple): Fixed variant
6126 structure initialization. Also fixed a typo (TYPE_NAME
6127 was being used on a FIELD_DECL instead of DECL_NAME).
6128 * c-typeck.c (initializer_constant_valid_p): Pass missing
6129 ENDTYPE argument on recursive call.
6130 (set_init_field): New function, needed by ch-convert.c change above.
6132 * ch-decl.c (layout_chill_variants): Added a FIXME next to an
6133 almost certain typo.
6135 * ch-expr.c (build_chill_arrow_expr): Call `build1' and set
6136 TREE_CONSTANT for static references.
6137 * ch-except.c (chill_start_on): Change calls to
6138 `build_unary_op' (which is C-specific) to `build_chill_arrow_expr'
6139 which has CHILL semantics.
6140 * ch-convert.c (convert): Ditto (albeit in some disabled code).
6142 Sat Jan 1 21:26:43 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6144 * ch-satisfy.c (safe_satisfy_decl): Reorder conditional test of
6145 TREE_CODE of DECL in case it's altered by actions in the switch.
6147 * ch-satisfy.c (satisfy): Undo abort added earlier on 1 Jan. CVS log
6148 mentions where to find code that triggers this case.
6150 * ch-actions.c (adjust_parm_or_field): Handle CONSTRUCTORS here as
6151 well.
6153 * ch-convert.c (digest_structure_tuple): Push to permanent_obstack if
6154 we're dealing with a CONSTRUCTOR that is TREE_PERMANENT.
6155 (digest_constructor): Ditto.
6157 Sat Jan 1 10:29:19 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6159 * ch-parse.y (handleraction,resultaction,assignaction,call): Modified
6160 so that CONSTRUCTORS are properly handled before being used.
6162 * ch-convert.c (chill_start_init): New function. All callers to
6163 `start_init' changed to call this function instead.
6164 (digest_struct_tuple): Defend against initialization machinery
6165 mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
6166 IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
6167 needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
6168 can be refered to throughout the compilation unit. Also remove an
6169 extraneous call to `process_init_element' erroneously added to the
6170 variant record sub-loop.
6171 (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
6172 CONSTRUCTORS of SET_TYPE.
6173 * ch-parse.y (build_chill_constructor): Refix typo. Also set
6174 TREE_STATIC if at top level.
6176 * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
6177 TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
6178 should have been called.
6180 * ch-convert.c (digest_struct_tuple): Restore code which tracks
6181 field initializations so that the compiler can deduce what variant
6182 initializations to assume.
6184 * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
6185 when we push into a scope that has a DECL with a CONSTRUCTOR as its
6186 DECL_INIT.
6188 * ch-parse.y (build_chill_constructor): Change the name of the
6189 parameter to something more meaningful. Fix typo. Also, handle case
6190 where element is an untyped CONSTRUCTOR.
6192 * ch-except.c (finish_handler_array): Set TREE_CONSTANT on
6193 constant ADDR_EXPRs.
6194 (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT
6195 on JBUF_REF (instead of calling `build1' which does not).
6197 * ch-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
6199 * ch-typeck.c (chill_expand_tuple): Deleted.
6200 * ch-parse.y (primval rule): Don't call `chill_expand_tuple';
6201 instead, use initialization machinery for CONSTRUCTORS that
6202 come through here.
6203 * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
6204 that are created here.
6205 * ch-satisfy (satisfy): Abort in case we would have called
6206 chill_expand_tuple. FIXME: some other code is needed here,
6207 but I don't know what yet.
6209 * ch-parse.y (build_chill_constructor): New function to
6210 propagate TREE_CONSTANT bits to CONSTRUCTORS.
6211 (untyped_expr rule): Use it.
6212 (primval rule): Use it.
6214 * ch-decl.c (do_decl): Call `finish_init'.
6215 * ch-convert.c (convert): If we spontaneously create a CONSTRUCTOR in
6216 this function, make sure the initialization machinery is set up.
6218 * ch-convert.c (digest_structure_tuple, digest_constructor): Add
6219 missing prototypes.
6221 Fri Dec 31 11:31:01 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6223 * ch-grant.c (chill_finish_module_code): Mark ADDR_EXPR built by hand
6224 as being TREE_CONSTANT. Otherwise it gets bounded by the initializer
6225 code.
6227 * ch-decl.c (do_decl): Change in CONSTRUCTOR handling due to...
6228 * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
6229 rewritten to work with GCC's initialization code. The basic change
6230 was to keep the initializers in sync with the initialization
6231 machinery that `process_init_element' imposes. Both of these
6232 functions now return `void'.
6233 * ch-convert.c (convert): Changed calls to `digest_...' functions.
6235 FIXME: the code handling UNION_TYPE (and variant records) has not
6236 been tested yet.
6238 Fri Dec 31 15:32:56 1993 Bill Cox (bill@rtl.cygnus.com)
6240 * ch-lex.l (convert_number): Output the converted number if
6241 yydebug is enabled.
6242 * ch-parse.y (signaldef): Set ignore_exprs correctly for a
6243 SIGNAL declaration.
6245 Fri Dec 31 13:17:48 1993 Bill Cox (bill@cygnus.com)
6247 * ch-parse.y: Cleanup handling of RETURN actions, to distinguish
6248 a RETURN without a value (which cannot have an exception
6249 handler) from a RETURN with a value (which can). Eliminate
6250 some shift/reduce and reduce/reduce conflicts.
6252 Thu Dec 30 17:42:32 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6254 * ch-inout.c (build_chill_writetext): Deal with 2 cases where
6255 types returned from `type_for_size' are not expected. FIXME.
6256 * ch-decl.c (init_decl_processing): Mark `char_type_node' unsigned.
6257 This is required when range checking is enabled.
6259 Thu Dec 30 14:28:25 1993 Bill Cox (bill@rtl.cygnus.com)
6261 DELAY CASE works now.
6262 * ch-decl.c (init_decl_processing): Move rest of tasking-related
6263 initialization into tasking_init().
6264 * ch-parse.y (delaycaseaction): Pervasive additions/corrections.
6265 (optsetprio): New non-terminal.
6266 * ch-tasking.c (get_task_name): Delete, obsolete.

6269 (build_receive_case_label): Move between start and end functions.
6270 (build_delay_case_start): Pass SET name and priority also.
6271 Generally update to correct functioning.
6272 (build_delay_case_label): Move between start and end fucntions,
6273 correct its functioning.
6274 (build_delay_case_end): Correct the code.
6275 (tasking_init): Lots of tasking-related code moved here from
6276 init_decl_processing.
6277 * ch-tree.h: Update, add prototypes.
6279 Wed Dec 29 10:13:10 1993 Bill Cox (bill@rtl.cygnus.com)
6281 * ch-expr.c (build_chill_indirect_ref): Revert change which
6282 failed full regression testing.
6283 * ch-lex.l (name_type_signal): Add debug output.
6284 * ch-parse.y (structured_variable): Add a debug variable.
6286 Wed Dec 29 02:05:51 1993 Bill Cox (bill@rtl.cygnus.com)
6288 * ch-decl.c (get_next_decl): Revert change which failed full
6289 regression testing.
6291 Tue Dec 28 18:20:14 1993 Bill Cox (bill@rtl.cygnus.com)
6293 DELAY actions work now.
6294 * ch-decl.c: Correct spelling in comments.

6298 * ch-expr.c (build_chill_indirect_ref): Prevent a syntax error from
6299 becoming a seg fault.
6300 * ch-grant.c: Correct a comment.
6301 * ch-loop.c: Delete/correct comments.
6302 * ch-parse.y (delaycaseaction): Add push/poplevel calls. Turn 'sorry'
6303 into rough draft of actual code.
6304 (delayaction): Don't make a new scope here, use get_unique_identifier
6305 instead.
6306 (locdec): process event decls here, too.
6307 (mode): Add code to forbid READonly EVENT and BUFFER decls. Delete
6308 code which required EVENTs and BUFFERs to be declared at global scope.
6309 (simple_name_string): Add an EVENTNAME.
6310 * ch-satisfy.c (safe_satisfy_decl): Prevent a syntax error from
6311 becoming a seg fault.
6312 * ch-tasking.c (tasking_setup): Add the event queue's max. length
6313 as the 'entry_point' parameter in the list.
6314 (build_receive_case_start, build_receive_case_label): Defer
6315 calling runtime routine until we know whether we have a signal
6316 or a buffer to wait for.
6317 (build_delay_case_start, build_delay_case_end,
6318 build_delay_case_label, build_delay_action,
6319 process_event_decls): Added functions.
6320 * ch-typeck.c (chill_similar): Allow all integers of differing
6321 precisions to be similar.
6323 Thu Dec 23 18:00:40 1993 Bill Cox (bill@rtl.cygnus.com)
6325 * gcc.c (CHILL SPECS): Delete references to -M -MM -MD -MMD
6326 options. Delete C-specific defines. Disable piping from
6327 pre-processor to cc1chill (even if -pipe is specified), since cc1chill
6328 rewinds its input for its second pass. Piping still works
6329 from cc1chill to as.
6331 Thu Dec 23 12:31:55 1993 Bill Cox (bill@rtl.cygnus.com)
6333 * ch-tasking.c (decl_tasking_code_variable): Assure that the
6334 tasking_code variable is allocated on the permanent obstack.
6335 (tasking_setup): Lots of changes - handle EVENT/BUFFER max.
6336 queue length (passed as the entry_point parameter).
6337 Other changes to variable names to increase 'self-documentation'
6338 the only kind GNU CHILL will get, for a while..
6340 Wed Dec 22 10:46:31 1993 Bill Cox (bill@rtl.cygnus.com)
6342 * ch-decl.c (do_seize): Delete - it's unused. Fix comments.
6343 * ch-loop.c (build_chill_iterator): Convert BY expression
6344 so loop involving a SET works. Additional errors generated
6345 for numbered SET expression as start or end expression.
6346 * ch-tree.h: Prototypes for future DELAY functions.
6347 * ch-typeck.c: Standard indentation.
6349 Tue Dec 21 15:30:57 1993 Per Bothner (bothner@kalessin.cygnus.com)

6364 Return 2 if also a referable.
6365 * ch-typeck.c (chill_referable): Re-define to use chill_location.
6366 * ch-tree.h (CH_EQUIVALENT): Re-defined to use chill_equivalent.
6368 * dbxout.c (dbxout_type): Output the type attribute "@S;" to
6369 distinguish a string from a char array, and to distinguish a
6370 bitstring from regulat (power)set. (Needed for Chill.)
6371 * dbxout.c (dbxout_type): Only check for baseclasses in
6372 type.binfo is a vector. (It is used in Chill for tagged unions.)
6374 Fri Dec 17 09:56:07 1993 Bill Cox (bill@rtl.cygnus.com)
6376 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
6377 ch-grant.c, ch-inout.c, ch-loop.c, ch-parse.y,

6391 names in receivecasealternative. Generate error messages
6392 if they're mixed in the same receive case.
6393 (process_buffer_decl): Renamed from build_buffer_decl.
6394 * ch-tree.h: Fix prototypes.
6395 * ch-typeck.c (smash_dummy_type): Handle all four kinds of LANG_TYPE

6405 * ch-loop.c (declare_temps): Calculate end-of-array pointer
6406 using correct type (NOT chill_integer_type).
6407 (begin_chill_loop): Build loop-bypass expression in the
6408 type of the start expression, not in the unsigned type.
6410 Tue Dec 14 15:41:32 1993 Per Bothner (bothner@kalessin.cygnus.com)
6412 * ch-decl.c (push_scope_decls): Re-arrange so that normal
6413 (non-seize) declarations are proclaim_decl'd *before* we
6414 handle the ALIAS_DECLs for seizes. The advantage is
6415 that we can now test for (an approximation) to the
6416 'seizeable' concept, thus avoiding duplicate definitions
6417 when a module has both GRANTs and SEIZE ALL.
6419 * ch-expr.c (build_chill_arrow_expr): No longer re-write
6420 addr-of-conversion to pointer-conversion-of-addr.
6421 * ch-expr.c (build_chill_addr_expr): Re-write to just use

6426 * ch-expr.c (build_chill_addr_expr, build_chill_addr_expr): Don't re-write
6428 * ch-tree.h (chill_root_resulting_mode): Fix typo (missing '_').
6430 * ch-expr.c (finish_chill_binary_op): Use CH_ROOT_RESULTING_MODE
6431 macro (which works on expressions), rather than CH_RESULTING_MODE
6432 (which works on modes, and isn't quite correct).
6433 * ch-tree.h (CH_IS_BOUND_REFERENCE_MODE): New macro.
6434 * ch-typeck.c (chill_read_compatible, chill_compatible):
6435 Use the new macro, which handles NEWMODEs of PTR correctly.
6436 * ch-typeck.c (chill_similar): Return 1 rather than 0 for
6437 dynamic-length array (and string) types (e.g. slices).
6438 * ch-typeck.c (chill_root_mode): If the mode has a Novelty,
6439 just return it as is. (This is still not 100% correct for
6440 NEWMODE of RANGEs, but is close enough.)
6442 Mon Dec 13 16:27:06 1993 Bill Cox (bill@rtl.cygnus.com)
6444 * ch-parse.y (locdec): Avoid passing IDENTIFIER_NODEs to

6447 of bufdecl closer to its use.
6449 Mon Dec 13 14:57:55 1993 Bill Cox (bill@rtl.cygnus.com)

6454 * ch-parse.y (sendaction): Delete unused statement, use the 'name'
6455 variable.
6456 * ch-tasking.c: Use expand_expr_stmt to avoid C-specific
6457 conversions.
6458 (build_buffer_decl): Save the tasking_code_variable's decl
6459 in the buffer decl tree.
6460 (build_buffer_descriptor): Real, working version.
6462 Mon Dec 13 03:13:36 1993 Bill Cox (bill@rtl.cygnus.com)
6464 * ch-decl.c (print_lang_identifier): Delete code
6465 to print buffer size - it's no longer kept here.
6466 * ch-parse.y (expand_send_buffer): Renamed from
6467 build_send_buffer.
6468 (locdec): Enable building of a buffer decl.
6469 (optresultspec, optresultattr): Add optional

6473 * ch-tree.h (build_send_buffer): Renamed.
6474 * ch-typeck.c (chill_expr_class): Do more complete,
6475 job of classifying expressions. Thanks, Per.

6480 for bitstring constants.
6481 * ch-typeck.c (chill_novelty): The novelty of an (unnamed)
6482 range mode is that of its parent mode; the novelty of READ M
6483 is that of M.
6485 Sat Dec 11 15:14:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
6487 * ch-expr.c (varying_to_slice): Call stabilize_reference
6488 rather than save_expr.
6489 * ch-typeck.c (build_chill_slice): Don't emit warning
6490 if array is a SAVE_EXPR (it is effectively referable).
6491 * ch-typeck.c (chill_root_resulting_mode): Handle
6492 correctly the case that one operand is DERIVED and one is VALUE.
6494 Fri Dec 10 10:00:42 1993 Bill Cox (bill@rtl.cygnus.com)

6516 assignment, check that all the targets are equivalent.
6518 * ch-typeck.c (chill_l_equivalent, CH_L_EQUIVALENT): New function

6520 * ch-typeck.c (chill_read_compatible): Implement at least
6521 initial check of read-only-ness.
6522 * ch-typeck.c (build_readonly_type): Fix thinkos.
6524 Wed Dec 8 09:11:46 1993 Bill Cox (bill@rtl.cygnus.com)
6526 * ch-decl.c (pop_module): Only warn about duplicate grant

6532 Tue Dec 7 17:10:36 1993 Per Bothner (bothner@kalessin.cygnus.com)
6534 * ch-decl.c (start_chill_function): Handle attributes in pass 1,
6535 rather than in pass 2. (It seems to make more sense that way.)
6536 * ch-parse.y (procedureattr): Build attribute list if pass != 2.
6538 * ch-parse.y (mode): Don't call build_readonly_type in pass 2.
6540 Mon Dec 6 14:35:31 1993 Per Bothner (bothner@kalessin.cygnus.com)
6542 This implements NOVELTY and READONLY checking.

6545 * ch-tree.h: New prototypes.
6546 * ch-decl.c (push_modedef): If newmode, lazily "copy" the given mode
6547 immediately (even if it's just a type name), using a LANG_TYPE.
6548 * ch-parse.y (mode): Call build_readonly_type to handle READ.
6549 * ch-decl.c (find_implied_types), ch-grant.c (raw_decode_mode),
6550 ch-satisfy.c (satisfy): Handle a LANG_TYPE.
6551 * ch-decl.c: Remove chill_modes_equiv and other unused junk.
6552 * ch-satisfy.c (safe_satisfy_decl/CONST_DECL): Better
6553 mode compatibility checking for SYN declarations.
6555 * ch-typeck.c (chill_similar): Be more general when checking set
6556 modes for similarity - specifically support calling chill_similar
6557 BEFORE the modes have been satisfied (needed by proclaim_decl).
6558 * ch-decl.c (proclaim_decl): Allow duplicate definitions
6559 of set elements of similar set modes.
6561 * ch-parse.y (caseaction): Call language-independent
6562 expand_start_case rather than c_expand_start_case (which

7054 * ch-typeck.c (build_chill_cast): Just return if already correct type.
7056 Re-do DO WITH so that build_component_ref for is done lazily
7057 (at each reference) instead of eagerly (at the beginning
7058 of DO WITH). This is needed for tagged variants,
7059 * ch-tree.def (WITH_DECL): New declaration tree code.
7060 * ch-decl.c (lookup_name): Recognize WITH_DECLs.
7061 * ch-decl.c (handle_one_level): Variant parts are currently

7107 builtins have a pointer-to-pointer-to-void
7108 first parameter, rather than a reference parameter.
7109 * ch-expr.c (build_allocate_memory_call,
7110 build_allocate_global_memory_call): Do automatic
7111 ADDR () on the first parameter, for backward

7148 code variables associated with a process or signal.
7149 * ch-tasking.c (build_gen_inst, build_gen_ptype): Use the decl's
7150 tasking_code_decl pointer, rather than trying to look it up
7151 in the hash table or linked scope list.
7153 Wed Oct 20 09:52:44 1993 Bill Cox (bill@rtl.cygnus.com)
7155 * ch-actions.c (lookup_and_handle_exit): Only output error message

7164 static variable, point the process' function_decl at it for later
7165 reference by build_start_process.
7166 (print_mode): Use CHILL upper-case convention to print modes.
7167 * ch-lex.l: Must initialize tasking-related trees to NULL at start
7168 of each pass, or we lose the fact that the user did or did not
7169 specify a value for each of them.
7170 * ch-parse.y (check_end_label, action, exceptlist): Only output
7171 error message in pass 1.
7172 (sendaction): Add comments.

7177 passes, using do_decl so we can pass the pass 2 value of the
7178 process_type or signal_code to it. Only update the process_type
7179 if the incoming pointer isn't null and pass == 2. Use a new
7180 parameter to know whether to include an init expression.
7181 (build_process_header): Attach tasking-code_variable to process

7197 generation for decls to not use DECL_ASSEMBLER_NAME.
7198 * ch-decl.c: Set DECL_ASSEMBLER_NAME to DECL_NAME.
7199 This matches C, and allows dbxout to emit proper user-level names.

7202 into the outer scope.

7218 * ch-tree.h: Restore old version.
7219 * ch-expr.c (finish_chill_binary_op): Convert TRUNC_DIV_EXPR
7220 to RDIV_EXPR if an operand is floating. (This functionality

7224 not error_mark_node.
7225 * ch-actions.c (chill_expand_assignment): Allow such borderline

7246 init_list entry.
7248 Sun Oct 17 15:16:54 1993 Bill Cox (bill@cygnus.com)
7250 * ch-convert.c: Move semicolon to separate line - easier to see.
7251 * ch-decl.c (do_decl): Handle untyped_expr initializers by
7252 simply using the variable's declared type - no compatibility
7253 check can be made if the expression has no type.

7255 the loop variable.
7256 (fold_set_expr): Fix two other endless loops by passing

7438 * ch-tree.h: Rename functions, add return values.
7440 Mon Oct 4 15:43:56 1993 Per Bothner (bothner@kalessin.cygnus.com)
7442 * ch-convert.c (digest_constructor): Convert element to element_type.
7443 * ch-parse.y (end_function): Use DECL_ARGUMENTS to check
7444 for parameterless process.
7446 Fri Oct 1 13:57:30 1993 Per Bothner (bothner@kalessin.cygnus.com)
7448 * ch-typeck.c (chill_location): New function.
7449 Based on lvalue_p, but also handle Chill-specific VARY_ARRAY_REF.
7450 * ch-typeck.c, ch-tree.h (CH_LOCATION_P), ch-convert.c: Use
7451 chill_location instead of lvalue_p.
7454 Fri Oct 1 11:28:42 1993 Bill Cox (bill@cygnus.com)
7456 * ch-convert.c (convert): Back out Michael's changes, unintentionally
7457 checked in.
7458 * ch-lex.l (handle_use_seizefile_directive): No longer downcase
7459 seize file names.
7460 * ch-parse.y (sendaction): Fix a couple of seg faults. Comment out
7461 SEND BUFFER processing for now.
7462 * ch-tree.h: Fix comment.
7464 Thu Sep 30 17:00:42 1993 Per Bothner (bothner@kalessin.cygnus.com)
7466 * ch-tree.h (CH_CHARS_ONE_P, CH_BOOLS_ONE_P): New macros,
7467 for recognizing singleton strings.
7468 * ch-tree.h (MARK_AS_STRING_TYPE): New macro.
7469 * ch-tree.c (build_string_type, build_bitstring_type),
7470 ch-convert.c (convert): Use it.
7471 * ch-typeck.c (build_chill_slice): Take length rather than upper
7472 bound. This makes it easier to recognize that A(X UP LENGTH)
7473 really has fixed length. Also, if the argument is string,
7474 mark the slice as a string too. Also, handle varying strings.
7476 * ch-typeck.c (conflate_singleton_strings): New global.
7477 * ch-typeck.c (chill_similar): If conflate_singleton_strings is
7478 set (as it currently is), allow CHARS(1)/BOOLS(1) to be similar
7479 to CHAR/BOOL, as required by the 1984 version of Z.200.
7480 * ch-convert.c (convert_to_char): Convert CHARS(1) to CHAR.
7481 * ch-convert.c ( build_array_type_for_scalar): If input is string,
7482 so is output.
7483 * ch-convert (maybe_turn_scalar_into_arra), ch-tree.h: Removed.
7484 * ch-convert.c (convert): Convert CHAR to CHARS(1).
7486 This fixes 'X // := Y' and is also a general simplification.
7487 * ch-actions.c (chill_expand_assignment): Convert 'LHS OP := RHS'
7488 to 'LHS := LHS OP RHS' (using stabilize_reference on LHS).
7489 Also, call save_expr on RHS if a multiple assignment.
7490 * ch-parse.y (assignaction): Therefore, no longer need to call
7491 stabilize_reference on RHS.
7492 * ch-typeck.c (build_chill_modify_expr), ch-tree.h: Remove
7493 modifycode parameter. Make it the caller's responsibility to
7494 handle <assigning operator>.
7495 * ch-actions.c, ch-decl.c, ch-except.c, ch-expr.c, ch-grant.c,
7496 ch-loop.c: Fix calls to build_chill_modify_expr accordingly.
7498 Wed Sep 29 18:02:55 1993 Per Bothner (bothner@kalessin.cygnus.com)
7500 * ch-lang.c (string_index_type_dummy), ch-tree.h: New variable.
7501 * ch-decl.c (integer_minus_one_node), ch-tree.h: New variable.
7503 * ch-parse.y (arrayindex: modename): Remove useless code.
7504 * ch-satisfy.c (satisfy): Don't gag on string_index_type_dummy,
7505 * ch-tree.c (build_string_type): Pass string_index_type_dummy as
7506 the parent type of the index range.
7507 * ch-typeck.c (layout_chill_range_type): Recognize and handle
7508 string_index_type_dummy - specifically allow an empty range.
7510 Wed Sep 29 13:36:23 1993 1993 Bill Cox (bill@cygnus.com)
7512 * ch-convert.c (convert_to_reference): Check for loc-identity
7513 mismatches correctly (and remove one of those chill_compatible
7514 calls).
7515 * ch-decl.c (decl_tasking_code_var): New function, called from
7516 push_extern_process and push_extern_signal.
7517 * ch-parse.y (end_function): Delete parameter. Check current_function_decl
7518 whether it's actually a process, and whether it has parameters.
7519 Make Michael's change simplifying the pass 2 test, preventing a seg
7520 fault.
7521 (procedure, process): Change calls to end_function, remove
7522 code saving value from build_process_header. Delete redundant chill_
7523 phrases from some function calls.
7524 * ch-tasking.c: Remove some redundant _chill phrases from function
7525 names.
7526 * ch-tree.h: Remove some redundant _chill phrases from function
7527 names. Add the CH_VARYING_ARRAY_TYPE macro, call it from
7528 all relevant places.
7529 * ch-typeck.c: Use the new macro. Cast TREE_CODEs to chill_tree_code.
7531 Wed Sep 29 13:07:43 1993 Per Bothner (bothner@kalessin.cygnus.com)
7533 * ch-convert.c (convert_to_reference): Remove redundancies.
7534 * ch-convert.c (convert): Handle convert_to_reference
7535 with a recursive convert call.
7536 * ch-decl.c (do_decl): Add missing compatibility-checking
7537 of initializer (don't depend on convert).
7539 Tue Sep 28 00:02:25 1993 Per Bothner (bothner@kalessin.cygnus.com)
7541 * ch-tree.h (CH_LOCATION_P): New macro.
7542 * ch-typeck.c (layout_chill_range_type): Fix call to
7543 type_for_size, when figuring out a defaulted parent type.
7544 * ch-expr.c (build_chill_lower, build_chill_sizeof): Check
7545 for TREE_CODE_CLASS != 't' rather than == 'd'.
7546 * ch-expr.c (build_chill_function_call): Use CH_LOCATION_P
7547 to check for location, rather than TYPE_CODE_CLASS == 'd'.
7549 * ch-tree.c (build_string_type): Make 2-pass safe. Also,
7550 change parameter to be length, not index type.
7551 * ch-parse.y (mode2), ch-expr.c (build_concat_expr), ch-lex.l
7552 (build_chill_string): Modify callers of build_string_type accordingly.
7553 * ch-lex.l (check_newline): Don't look for # directive inside a
7554 C-style comment.
7555 * ch-grant.c (grant_array_type): Make more robust for char-
7556 and bit-strings (allow non-constant sizes). Change parameters
7557 and return types. (raw_decode_mode): Use grant_array_type
7558 for bitstrings. (otherwise): Fix grant_array_type callers.
7560 Mon Sep 27 16:57:57 1993 Per Bothner (bothner@kalessin.cygnus.com)
7562 Remove changes of Sep 15.
7563 * ch-tree.h (CH_SINGLETON_DOMAIN): Removed.
7564 * ch-typeck.c (chill_similar): Don't allow a singleton
7565 powerset to be similar to its domain.
7566 * ch-convert.c (convert_to_boolean): Don't convert a singleton
7567 SET_TYPE constructor to a Boolean.
7569 * ch-actions.c (chill_expand_assignment): Handle IN_EXPR on
7570 LHS of assignment, which is what we're current (temporarily?) using.
7572 Mon Sep 27 06:01:57 1993 Bill Cox (bill@rtl.cygnus.com)
7574 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
7575 ch-grant.c, ch-inout.c, ch-parse.y, ch-satisfy.c,
7576 ch-tasking.c, ch-tree.c, ch-tree.h, ch-typeck.c:
7577 -Wall cleanup. Add prototypes where missing.
7578 Delete unused variables. Cast uses of tree_codes
7579 to chill_tree_code, which they are.
7581 Sun Sep 26 13:09:57 1993 Bill Cox (bill@rtl.cygnus.com)
7583 * ch-decl.c (do_decl): Save initializer in pass zero
7584 case also.
7585 * ch-lex.l: Fix comments, indentation.
7586 * ch-parse.y: Standardize error messages to use
7587 uppercase for CHILL keywords rather than quoting them.
7588 Suggestion from docs department.
7589 * ch-tasking.c: Pervasive changes to get processes to
7590 compile and START.
7591 * ch-tree.h: Delete prototypes for functions whic
7592 I made static inside ch-tasking.c.
7594 Sun Sep 26 02:40:02 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7596 * ch-lex.l (yywrap): Call `check_newline' in case the file
7597 started with a line directive.
7599 Sat Sep 25 13:54:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
7601 * ch-decl.c: Expand pre-amble comment.
7602 * ch-decl.c (struct scope, push_module): Use new field
7603 tail_chain_module to build child-module list in order.
7604 (Just to make compiler debugging a little less confusing.)
7606 * ch-decl.c (struct scope): New field weak_decls.
7607 * ch-decl.c (find_implied_types): New interface. Now pre-pend
7608 new enum types to a given input list. This makes it easier to
7609 avoid duplicates, which should at least be more efficient.
7610 Also, handle FUNCTION_DECL.
7611 * ch-decl.c (bind_saved_names): Removed. Distribute its
7612 functionality over new functions (push_scope_decls, pop_scope_decls,
7613 build_implied_names, bind_sub_modules). The goal (which seems to
7614 have been more-or-less attained) was to fix weak name handling.
7615 * ch-decl.c (poplevel): Use new function pop_scope_decls.
7617 * ch-tasking.c (build_signal_struct, build_tasking_message_type):
7618 Use build_decl directly, rather than grok_chill_fixedfields
7619 (which depends on ignore_exprs and has more overhead).
7620 * ch-tasking.c (build_signal_struct): Construct the type
7621 only in pass 1.
7622 * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
7623 than build_array_ref (which does C-specific "optimizations").
7624 (Hence move my_build_array_ref up earlier in the file.)
7626 Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7628 * ch-tasking.c: Declare static variable `void_ftype_void'.
7629 (chill_tasking_init): Initialize `void_ftype_void' here.
7630 (build_tasking_struct): Use, don't declare `void_ftype_void'.
7631 (generate_tasking_code_variable): Call `do_decl', not
7632 `decl_temp1' to declare TASKING_CODE_NAME.
7633 (tasking_setup): Drop into 1-pass mode so that all
7634 tasking-related declarations are installed in the global
7635 scope. Use correct CHILL types for initializers (since
7636 ptr_type_node doesn't have the right meaning for CHILL).
7637 Also, call `do_decl' instead of `decl_temp1' for
7638 `init_struct'.
7639 (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
7640 `chill_finish_compile' in sync between passes.
7642 * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
7643 declarations on pass zero. Keep obstacks in sync, and always
7644 call `finish_decl' for pass zero declarations.
7645 (push_chill_extern_function): Keep obstacks in sync, and always
7646 call `finish_decl' for pass zero declarations.
7647 (build_enumerator): Ditto.
7648 (grok_chill_variantdefs): Change PASS test to exclude only
7649 pass one.
7650 (finish_struct): Ditto.
7651 * ch-expr.c (build_chill_component_ref): Ditto.
7652 (build_chill_binary_op): Ditto.
7653 * ch-tree.c (build_powerset_type): Ditto.
7654 (build_bitstring_type): Ditto.
7655 * ch-typeck.c (build_chill_range_type): Ditto.
7656 (build_chill_struct_type): Ditto.
7658 * ch-decl.c (build_chill_exception_decl): Clarify reasons for
7659 extra pushing and popping of obstacks.
7661 * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
7662 on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
7664 * ch-grant.c (chill_finish_compile): Clear out both
7665 MODULE_INIT_LIST and TASKING_LIST if either contains stuff
7666 from pass one.
7668 * ch-parse.y (rccase_label): Add NAME rules so that pass one
7669 works w/o knowing we're parsing a signal. Simplify SIGNALNAME
7670 rules since we only get SIGNALNAME tokens in pass two.
7671 (sendaction): Ditto.
7672 * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
7673 BUFFERNAME on pass two. The grammar now handles this.
7674 * ch-decl.c (lookup_remembered_decl): Deleted.
7676 Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
7678 * ch-decl.c (lookup_remembered_names): Removed. It was being
7679 misused in ch-lex.l.
7680 * ch-lex.l (name_type_signal): Revert last change. Basically,
7681 we cannot use the C typedef/variable name trick in CHILL, due
7682 due to the language's 2-pass nature.
7683 * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
7684 a seg fault.
7685 * ch-tree.h (lookup_remembered_name): Comment out the prototype.
7687 Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7689 * ch-decl.c (do_decl, push_chill_extern_function): Change pass
7690 checks so the pass == 0 case is handled for built-in types.
7691 (push_modedef): Add check for error_mark_node.
7692 (lookup_remembered_decl): New function.
7693 (pushlevel, poplevel) Change pass checks.
7694 (pushdecl): Check type as well for NULL.
7695 (build_enumerator): Handle pass == 0 case.
7696 * ch-lex.l: Use lookup_remembered_decl to get lastiddecl
7697 during pass 1.
7698 * ch-parse.y: Set pass to zero to indicate initial decl processing.
7699 Replace NAME references with SIGNALNAME references.
7700 (startaction): Only check copy number if not ignoring actions.
7701 Always call build_chill_start_process.
7702 (optstartset): Don't lookup the instance name.
7703 * ch-tasking.c (generate_tasking_code_variable): Replace
7704 do_decl call with decl_temp1 call.
7705 (build_chill_start_action): Check for ignore_actions here.
7706 (build_tasking_message_type): Layout the type.
7707 (rc_state_type): New structure to keep nested receive-case
7708 info in.
7709 (build_chill_receive_case_start, build_chill_receive_case_end):
7710 Use the new struct.
7713 Fri Sep 24 04:19:15 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7715 * ch-tasking.c (build_chill_receive_case_start): `namedecl'
7716 should be a _DECL, not an IDENTIFIER_NODE.
7718 Thu Sep 23 18:18:24 1993 Per Bothner (bothner@kalessin.cygnus.com)
7720 * ch-decl.c (find_implied_types): Handle VAR_DECLs.
7722 * ch-decl.c (print_lang_identifier): Print IDENTIFIER_OUTER_VALUE.
7723 * ch-actions.c (chill_expand_result): Allow value-less RETURN.
7724 * ch-expr.c (resolve_component_ref): Recognize error_mark.
7726 * ch-convert.c (digest_constructor): Handle a nested powerset tuple.
7727 * ch-satisfy.c (satisfy): Use return value of layout_chill_range_type.
7728 * ch-typeck.c (chill_similar): Repeatedly get parent modes
7729 of ranges, not just once.
7730 * ch-typeck.c (chill_root_resulting_mode), ch-tree.h: New function.
7731 * ch-typeck.c (layout_chill_rang_type): Re-do type-checking
7732 to follow Blue Book better (check for Compatibility).
7734 * ch-tree.h (CH_ROOT_RESULTING_MODE): New macro.
7735 * ch-lex.l (use_seizefile_name, current_seizefile_name), ch-tree.h:
7736 New variables. The latter replaces in_seizefile.
7738 Changes to store in the new DECL_SEIZEFILE field each seize
7739 ALIAS_DECL the name in the most recent use_seize_file directive.
7740 (This requires that use_seize_file directives written to the
7741 grant file be written before the SEIZEs that need it.)
7742 Allow clashing declarations granted into the global scope
7743 (produce a warning), but remember the seizefile case from
7744 (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
7745 The a SEIZE will select the granted decl that matches its
7746 DECL_SEIZEFILE (in other words: grants from the most recent
7747 use_seize_file will be preferred).
7748 * ch-tree.h (DECL_SEIZEFILE), ch-tree.def: New macro.
7749 * ch-tree.h (global_value, IDENTIFIER_GLOBAL_VALUE): Renamed
7750 to outer_value, IDENTIFIER_OUTER_VALUE.
7751 Changes to cause the use_seize_file directives to be written
7752 out in order as they're seen in source.
7753 * ch-lex.l (files_to_seize, next_file_to_seize, last_file_to_seize):
7754 Changed to have type TREE_LIST of pointer to IDENTIFIER_NODE.
7755 * ch-lex.l (handle_use_seizefile_directive): Modify appropriately.
7756 Don't call grant_use_seizefile.
7757 * ch-lex.l (mark_use_seizefile_written): New function.
7758 * ch-grant.c (decode_decl): Write out use_seize_file directive,
7759 if needed, before writing a seize declarations.
7760 * ch-decl.c (pop_module): Handle decls granted into the global
7761 module specially, setting IDENTIFIER_OUTER_VALUE.
7762 * ch-decl.c (lookup_name_for_seizing): Check IDENTIFIER_OUTER_VALUE.
7764 Thu Sep 23 19:05:37 1993 Bill Cox (bill@cygnus.com)
7766 * ch-decl.c (push_chill_extern_process): Delete unused variables,
7767 declare the process' tasking_code variable as external.
7768 * ch-parse.y (process): Force ignore_exprs to FALSE while parsing
7769 the process header.
7770 * ch-tasking.c (sigdef): Move resetting of quasi_signal from here
7771 to (signaldef).
7772 * ch-tree.h: Add prototype.
7773 * expr.c (store_constructor): Emergency first-aid. Rewrite later.
7775 Thu Sep 23 12:57:53 1993 Per Bothner (bothner@kalessin.cygnus.com)
7777 * ch-expr.c (build_chill_function_call): Move possible call to
7778 chill_start_module_code until we know we're not calling a builtin.
7779 * ch-decl.c (save_expr_under_name): Use pushdecllist,
7780 not proclaim_decl (which provide for popping the decl).
7781 * ch-parse.y (optname): Also allow TYPENAME.
7783 Thu Sep 23 09:18:35 1993 Bill Cox (bill@cygnus.com)
7785 * ch-decl.c (print_lang_decl): Make weak name output more standard.
7786 (print_lang_identifier): Make signal-data flag output more standard.
7787 (push_chill_extern_process): Pass correct arg tree to
7788 push_chill_extern_function.
7789 (push_syn_decls, fixup_unknown_type, chill_modes_equiv):
7790 Standardize function header layouts (Makes the tcov script
7791 work better).
7792 * ch-except.c (chill_finish_on): Standardize function header.
7793 * ch-expr.c (fold_set_or): Standardize function header.
7794 * ch-grant.c (print_proc_tail, print_proc_exceptions): Standardize
7795 function headers.
7796 (decode_constant): Make sure that alpha operators are surrounded
7797 with whitespace.
7798 * ch-parse.y: Spell Z.200 correctly in comments.
7800 Wed Sep 22 10:42:31 1993 Per Bothner (bothner@kalessin.cygnus.com)
7802 * ch-expr.c (build_chill_addr_expr), ch-tree.h: New function.
7803 * ch-parse.y, ch-decl.c (shadow_record_fields): Use it.
7804 * ch-lex.l (handle_use_seizefile_directive): Don't emit
7805 use_seize_file directive if in_seizefile.
7807 * ch-convert.c (digest_structure_tuple): Fix code that checks
7808 for excess init values.
7809 * ch-decl.c (layout_chill_variants): Move increment of nlabels
7810 inside the proper loop.
7811 * ch-grant.c (print_struct): Add missing loop for tag_list.
7812 (print_struct): Look for variant fields by checking for a
7813 UNION_TYPE, not a NULL name, since we must use a dummy name.
7814 * ch-parse.y (structured_variable): Various fixing.
7815 * ch-decl.c (shadow_record_fields): Rename arg decl -> struct_val.
7817 * ch-satisfy.c (safe_satisfy_decl): Disable copying of modes
7818 for NEWMODE (and hence novelty checking), until we figure out
7819 a better way.
7821 * ch-except.c (finish_handler_array): Use null_pointer_node,
7822 not integer_zero_node (which fails to type-check).
7824 * c-typeck.c (get_constructor_element_type): New function.
7825 * ch-tree.h (CH_NOVELTY_FLAG): Now also used in TYPE_DECLs.
7826 (CH_NOVELTY): Redefined to call new function chill_novelty.
7827 (CH_CLASS_IS_XXX, TYPE_NEWMODE, CH_CLASS_MODE): Removed.
7828 * ch-typeck.c (classify_chill_expr renamed to chill_expr_class):
7829 Take extra output parameter (for M, as in M-value class).
7830 * ch-typeck.c (chill_novelty): New function. (Also de-references.)
7832 * ch-expr.c (resolve_component_ref, build_chill_component_ref):
7833 New functions. Handle 2-pass and variant records.
7834 * ch-parse.y (primval DOT name): Use instead of build_component_ref.
7835 * ch-satisfy.c (satisfy, case COMPONENT_REF):
7836 New case, call resolve_component_ref.
7838 * ch-expr.c (build_generalized_call): Extract single arg from
7839 arg list before calling build_chill_cast.
7841 * ch-parse.y (defining_occurrence_list): New non-terminal.
7842 Use it to replace locnamelist, synnames, and modenames.
7843 * ch-parse.y: Re-write parsing of variant records.
7845 * ch-decl.c (grok_chill_variantdefs): Now return a FIELD_DECL
7846 rather than just its type.
7847 * ch-inout.c (build_chill_io_list_type), ch-parse.y:
7848 Change callers appropriately.
7850 * ch-tree.h (TYPE_TAG_VALUES): Add an extra level of TREE_LIST,
7851 to support multiple tag fields.
7852 * ch-grant.c (print_struct), ch-decl.c (layout_chill_variants):
7853 Support multiple tag fields.
7855 * ch-convert.c (remove_tree_element, digest_structure_tuple):
7856 New functions, to digest structure tuples, without calling the

7880 doing the type's layout.
7881 (processpar): Use paramnamelist, but reformat it into a

7885 type's layout.
7886 * ch-tasking.c (generate_tasking_code_variable): Call do_decl to

7927 Fri Sep 10 12:23:41 1993 Wilfried Moser (fs_moser@cygnus.com)
7929 * Makefile.in: Change installation of the chill script. gcc will

9131 labels aren't lowercased before their time. Add BEGIN
9132 INITIAL before starting pass 2, so the header is

10362 to end of parameter types list.
10364 * ch-grant.c (chill_start_module_code): Make sure module

10466 (finish_chill_enum): Enum constants are marked with
10467 CH_DECL_ENUM so they don't get written to the grantfile.
10468 * ch-tree.h (IDENTIFIER_GRANTED_VALUE): Allow fast seizing.
10469 * ch-lex.l: Re-write to use start states, to avoid calling
10470 yylex() recursively.
10471 * ch-lex.l (compiler_directive); This is now obsolste. FIXME.
10472 * ch-lex.l: Call push_module and pop_module when reading a
10473 seizefile. This creates a pseudo-module.
10474 * ch-parse.y: Clean up handling of empty declarations and
10475 action statements; semicolons are now optional a number of
10476 places.
10477 * ch-parse.y: Remove some bogus tests for "statement
10478 out of sequence" (they're both legal and work).
10479 * varasm.c (mak_function_rtl): Remove kludge that may
10480 not be necessary (and loses anyway).

10503 * ch-grant.c (chill_grant): Test that a declaration is
10504 visible before writing it.
10505 * ch-parse.y (push_module): Make sure to hide declarations

10520 assignment, clean up.
10521 * ch-typeck.c: Add prototype for require_complete_type.

10531 * ch-decl.c (massage_param_node): New function.
10532 It handles the LOC/IN/OUT/INOUT parameter distinction,
10533 as well as calling build_chill_array_parm_type if needed.
10534 * ch-tree.h (massage_param_node): New prototype.
10535 * ch-decl.c (push_parms): Use new massage_param_node().

10540 lower bounds.
10541 * ch-actions.c (build_chill_function_call): If the formal

10545 the pseudo struct type is allocated on the permanent_obstack.
10546 * ch-parse.y (location): Remove thinko.
10547 * ch-actions.c (chill_comptypes): Comment out test for

10570 * ch-typeck.c (my_build_array_ref): Add some more code from
10571 build_array_ref. Change checks, error messages to mention
10572 'discrete types'. I.E. types which don't kiss and tell..

10582 Fri Apr 2 21:55:14 1993 Per Bothner (bothner@rtl.cygnus.com)
10584 Major re-write of New module/seize/grant stuff.
10585 Now, a grantfile is a spec module and contains all the
10586 top-level declarations of the granting module, not just
10587 those that are granted. It also contains explicit grant
10588 statements naming those declared names that are granted.
10589 It also has seize statements and use_seize_file directives
10590 to correctly handle transitive dependencies.
10592 * ch-parse.y: Change to allow multiple modules per source file.
10593 Allow spec modules (including quasi definitions) as well as
10594 regular modules.
10595 Allow spec modules inside normal modules; these behave as if
10596 they were outermost. This violates the Blue Book, but is
10597 needed by the new grantfile mechanism. (A grant file is a
10598 spec module that gets included by the use_seize_file directive.)
10599 * ch-parse.y (struct module *current_module, push_module,
10600 pop_module): Support module nesting (for spec modules only).
10602 * ch-tree.h (struct module): New.
10603 * ch-grant.c (granted_decls): New list of declarations
10604 that have been granted into the outermode pseudo-module.
10605 * ch-grant.c (decode_mode): If the decl has a name,
10606 always write the name, not just if the decl has already
10607 been written. Since we write out all decls, we can assume
10608 it will be written later, and depend on the forward
10609 declaration kludges to catch it.
10610 * ch-grant.c (decode_decl): Don't write out _EXTERN.
10611 Instead write out standard (Blue Book) quasi-definitions.
10612 * ch-grant.c (push_granted): New function.
10613 * ch-grant.c (seize_implied_names): New function. Re-write
10614 how set element names are seized when a set type is seized.
10615 * ch-grant.c (chill_seize): Work by seraching the
10616 granted_decls list and copying the declaration.
10617 * ch-grant.c (chill_grant): Write all declarations
10618 declared in this module. Write GRANT statements for
10619 those granted. seize statements for decls seized from
10620 other modules. Write extra syntax to make a complete
10621 spec module.
10622 * ch-grant.c (grant_use_seizefile): Copy use_seize_file
10623 directives into grant file.
10624 * ch-lex.l (setup_seizefile_read): Call grant_use_seizefile.
10626 * ch-lex.l (struct input_state, current_input_state,
10627 push_input_file, pop_input_file): New (type, variable,
10628 function*2). Used to save and restore state on an input file.
10629 * ch-lex.l: Clean up to handle nested input seizefiles
10630 (needed by new grant/seize mechanism.
10631 * ch-lex.l (skip_to_end_of_directive): New function.
10632 * ch-lex.l (compiler_directive: USE_SEIZE_FILE): Make sure
10633 we skip to the end of the directive *before* we switch
10634 input files.
10635 * ch-lex.l (setup_seizefile_read): Prevent reading the
10636 same seizefile twice (otherwise likely with new grant/seize).
10637 * ch-lex.l: Recognize SPEC. Misc cleanups.
10639 * ch-parse.y: Fixed foreward references of types.
10640 Removed the unknown_type_node crock.
10641 * ch-decl.c: Remove all uses of unknown_type_node.
10642 Check for TYPE_SIZE zero instead.
10643 * ch-decl.c (fixup_unknown_type): Make sure new mode
10644 gets copied into old mode. Merge their variant chains.
10645 * c-decl.c (lookup_name_current_level): Make non-static.
10646 * ch-decl.c (lookup_name_current_level): No longer needed.
10648 * ch-parse.y (call): Allow an implicitly defined function
10649 name following the CALL keyword.
10650 * ch-tree.h (struct lang_identifier): Add implicit_decl,
10651 and make sure order of fields matches c-tree.h.
10653 * ch-actions.c (lang_init, build_allocate_memory_call,
10654 build_allocate_globals_memory_call): Fix names (add initial '_')
10655 and prototypes of _allocate_[global_]memory (2nd param is ref).
10656 Use build_chill_function_call, not build_function_call,
10657 so the reference parameter gets handled.
10658 * ch-actions.c. (lang_init): Make sure boolean_{true,false}_node
10659 have boolean_type_node as their types.
10660 * ch-actions.c (build_chill_lower, build_chill_upper): Fix to
10661 work for arrays with BOOLEAN_TYPE ranges (and simplify some).
10663 * ch-except.c: Make sure an end_label is generated,
10664 and jump to it if there is no exception.
10666 * ch-convert.c (convert_to_reference): Strip off NOP_EXPR casts.
10667 * expr.c (expand_expr): Handle NOP_EXPR as Chill-style casts.
10668 (Need cleaning up and FSF installation!)
10669 * ch-parse.y: If taking the address of a cast, move the
10670 ADDR_EXPR inside the NOP_EXPR.
10672 * ch-typeck.c (my_build_array_ref): Simplified, more suitable
10673 versions of build_array_ref from c-decl.c. (E.g. don't barf
10674 if index type is char or bool.)
10675 * ch-typeck.c (build_chill_array_ref): Use my_build_array-ref.
10677 * ch-typech.c (build_chill_bin_type): New function.
10678 Support BIN(N) range type specification.
10679 * ch-parse.y (mode2), ch-lex.l: Recognize BIN(N).
10681 * ch-tree.h (CH_SIMILAR): Redefine in terms of chill_similar.
10682 * ch-typeck.c (chill_similar): New function. Recognize that
10683 that range types are similar to their parent types.
10685 * ch-tree.h: Declare flag_local_loop_counter.
10686 * ch-loop.c: Whether the loop variable is local to the loop
10687 in now controlled by flag_local_loop_counter, instead of
10688 #ifdef'd on CREATE_SCOPE.
10689 * ch-actions.c (lang_decode_option): Recognize flags
10690 "-f[no-]local-loop-counter".
10691 * toplev.c (lang_options): Add Chill flags -f[no-]local-loop-counter.
10693 * varasm.c (make_function_rtl): Due to problems with forward
10694 references, don't rename nested functions in Chill. (Kudge!)
10696 Sun Mar 28 10:12:45 1993 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10698 * ch-lex.l (push_back, readstring): Fix prototypes.
10700 Fri Mar 26 18:32:15 1993 Bill Cox (bill@rtl.cygnus.com)
10702 * ch-parse.y: Put %type directives back into alpha order.

10706 Fri Mar 26 13:36:23 1993 Bill Cox (bill@rtl.cygnus.com)
10708 * ch-lex.l (convert_charliteral): Rewrite to avoid bogus error msg.
10709 * ch-parse.y (get_type_of): Add function to deal with possible fwd
10710 declared type name. Call it from lotsa places. Add lotsa checks
10711 for error_mark_node. Standardize indentations.

10717 * ch-parse.y (action): Add recognition for allocate_memory and
10718 allocate_global_memory system calls.
10719 (mode2): Remove ill-conceived error check that broke REFs to
10720 as-yet-undeclared types. Check for IDENTIFIER_NODE, lookup its
10721 DECL if there, pass TREE_TYPE of decl to build_pointer_type.
10722 (variantfields, varianthack): Clean up.
10723 (variantfield): Check for IDENTIFIER_NODE, lookup its DECL if
10724 there, pass TREE_TYPE of decl to grok_fixedfields.
10725 (labellist): Explicitly assign error_mark_node to signal error.
10726 * ch-typeck.c (chill_compatible): Report FALSE for bad parameters,
10727 rather than seg faulting.
10729 Thu Mar 25 10:35:58 1993 Bill Cox (bill@rtl.cygnus.com)
10731 * ch-actions.c (lang_init): build_function_type for allocate_memory
10732 and allocate_global_memory runtime routines. Move discrete_type_p
10733 into ch-typeck.c.
10734 * ch-typeck.c (discrete_type_p): Move here, where it belongs, call it
10735 in build_chill_cast.

10745 avoid abort.
10747 Tue Mar 23 09:03:35 1993 Bill Cox (bill@rtl.cygnus.com)
10749 * ch-actions.c (build_char_array_expr): Just build a type for the

10751 chill_expand_array_assignment can do a better job of
10752 code-generation.
10753 * ch-expr.c (chill_expand_array_assignment): Generate the CONCAT_EXPR
10754 code.
10756 Mon Mar 22 12:42:58 1993 Per Bothner (bothner@rtl.cygnus.com)

10759 array and its type get on the permanent obstack.
10760 * ch-grant.c (write_grant_file): Don't write the _INIT=name
10761 specifier: It isn't needed, and loses (because of funny
10762 characters in the chill_initializer_name).
10763 * ch-decl.c (push_synmode): Set TYPE_NAME(mode) = syndecl.
10764 * ch-lang.c (finish_chill_enum): Don't allocate a dummy
10765 TYPE_DECL for the enum. I don't think it is needed (?),
10766 and removing it is needed for the change above.
10768 * ch-grant.c (grant_array_type, decode_mode): Remove unused
10769 'decl' parameter.
10770 * ch-grant.ch (raw_decode_mode): New function, based on old

10773 raw-decode_mode - but does not call raw_decode_mode if the
10774 type is named and has already been emitted.
10776 Fri Mar 19 11:55:35 1993 Bill Cox (bill@rtl.cygnus.com)
10778 * ch-actions.c: Add prototypes, remove unused variables. Attempt to
10779 continue generating grant file in presence of error (Wilfried's
10780 patch to lang_finish).
10781 * ch-expr.c: Change assign_stack_temp calls so temps get recovered
10782 after each statement. Move convert call into
10783 chill_expand_assignment from ch-parse.y.
10784 * ch-grant.c: Generally re-order, clean up. Include Per's decode_mode
10785 simplification. Include commented-out hack in decode_mode to return
10786 type's name if type SEIZEd or already GRANTed in this file.
10787 * ch-lex.l: Add prototypes.
10788 * ch-parse.y (assignaction): Move convert call into

10802 * ch-parse.y (structured_variable): Return NULL_TREE is invalid WITH
10803 parameter is seen, don't count it in structured_variable_list. Pre-
10804 vents seg fault when only WITH operand is invalid.
10805 * ch-parse.y (label_spec): Correct assignment within IF expression which
10806 was intended to be equality test. Remove unused variables.
10807 * ch-tree.h: Add prototype. Remove unused EXCP_CODE enumeration, and
10808 prototyping editorial comments.
10809 * ch-typeck.c: Disable generation of code to validate array index for
10810 now. Should be done as a call-back from more generic array_ref code.
10811 Clean up parameter checking. Remove unused variables.
10813 Fri Mar 12 11:57:32 1993 Bill Cox (bill@rtl.cygnus.com)

10871 Thu Mar 4 18:05:43 1993 Bill Cox (bill@rtl.cygnus.com)
10873 * ch-actions.c: Define builtin '__nepowerset' and call it - avoid
10874 negating the result of calling __eqpowerset. New function

10914 scope, for CHILL.
10916 Fri Feb 26 07:14:34 1993 Bill Cox (bill@rtl.cygnus.com)

10921 call in build_chill_cause_exception.
10922 * ch-convert.c, ch-expr.c: Use tree_cons to build list's last entry
10923 * ch-loop.c (build_temporary_variable): New function
10924 * ch-process.c: Call build_temporary_variable, spell start_process

10930 * c-decl.c (init_decl_processing): Disable initial creation of C-specific
10931 builtins - they pollute the CHILL name space.
10932 * ch-typeck.c (valid_array_index): Correct upper-bound check.
10933 * expr.c (expand_expr): Use actual library name for __inpowerset
10934 builtin.
10935 * stor-layout.c (variable_size): Disable complaint about variable-
10936 size type or decl at file scope. Perhaps later this s.b. a warning.

10943 * ch-actions.c: Change all builtin functions names to their
10944 actual library names. Change references to boolean_type_node
10945 to references to the TREE_CODE == BOOLEAN_TYPE, to follow the
10946 convention.
10947 build_set_expr: Remove length parameter, call powersetlen() instead.
10948 remove handling of CHAR arrays - they're handled in build_char_array_expr.
10949 Call __eqpowerset to test for equality - we can't use a byte-length -
10950 need bitcount instead.
10951 build_chill_compound_expr, internal_build_compound_expr: Copy from C
10952 version that does stuff we don't want.
10953 build_binary_op: Check for in_size_in_bytes return < 0, indicating

10955 string concatenation.
10956 powersetlen: Add function.
10957 build_chill_card: Call powersetlen.
10958 build_chill_max_min: Common code for powerset max/min.
10959 build_chill_length: Move VARYING array handling before regular char
10960 array handling.
10961 * ch-expr.c chill_expand_expr: Disable concatenate code - we need to
10962 the VARYING status of the target to do this correctly. Use powersetlen
10963 for the powerset operations, not a byte length.
10964 * ch-loop.c: Make CREATE_SCOPE #define to enable creation of a new scope
10965 for each CHILL loop, as Z.200 requires. Add powerset and error flags
10966 to loop structure. Evaluate user's powerset expression into a temp,
10967 scan it destructively with __ffsetclrpowerset or __flsetclrpowerset
10968 for powerset loop. Only do loop-end assignments if NOT a powerset
10969 loop, which has much less overhead now.
10970 * ch-tree.h: Add prototype for powersetlen.

10983 we are going to return 0.
10985 * ch-convert.c (convert_to_reference): Don't use
10986 TYPE_MAIN_VARIANT, because REFTYPE's type may be a newmode
10987 (which must match the type of the expr).
10989 * ch-grant.c (chill_seize): Don't let a type be copied just
10990 because we are seizing it.

10993 TYPE_MAX_VALUE to integer type.
10995 * ch-loop.c (begin_for_range): Set lp->iter_type based on the
10996 tree type of the bounds.
10997 (build_loop_top): type of GE_EXPR and LE_EXPR is
10998 boolean_type_node, not lp->iter_type.
10999 (for_location): Ditto.
11001 * ch-action.c (build_chill_lower,build_chill_upper): Handle
11002 ENUMERAL_TYPE. Also, handle different kinds of arguments more

11015 comes out error_mark_node, set ERRONEOUS.
11017 * ch-actions.c (build_chill_binary_op_1): If EXP is NULL_TREE,
11018 don't use it.
11020 * ch-action.c (chill_comptypes): Test for structural
11021 equivalence of enums.
11023 * ch-typeck.c (build_chill_array_ref): Convert INDEX to
11024 TYPE_MIN_VALUE of DOMAIN if the types are compatible.
11026 * ch-grant.c (chill_seize): If DECLS is a TYPE_DECL for an
11027 ARRAY_TYPE, seize the domain type if its a set.

11088 * ch-convert.c (convert): Slightly more correct conversion
11089 for ARRAY_TYPEs (return as OK if CH_COMPATIBLE).
11090 * ch-expr.c (chill_expand_array_assignment): Invoke
11091 __builtin_memcpy using build_function_call, not directly at
11092 the rtx level (which doesn't work).

11108 * ch-decl.c (grok_chill_variantdefs): Really implement variant
11109 records for CHILL.
11110 * ch-grant.c (get_tag_value): New function.
11111 * ch-grant.c (decode_mode): Grant variant records.

11142 special-case support for a BIT_FIELD_REF in right-hand-side.
11143 * ch-lang.c (finish_chill_enum): Patch up enum elements to
11144 have the correct type (instead of integers, as in C).
11146 * ch-lex.l, ch-parse.y: Add disgusting hack (involving
11147 context-dependent look-ahead) so we can parse exception
11148 handlers correctly.
11149 * c-typeck.c (digest_init): Set output type for SET_TYPEs.
11150 * varasm.c (unpack_set_constructor): Add support for

11187 * ch-lex.l (convert_bitstring), Changed SET_TYPE_CONSTRUCTOR to
11188 take a list of elements which are in the set. This corresponds
11189 better to the tuple input form in Chill (and Pascal).
11190 * varasm.c (unpack_set_constructor, pack_set_constructor):
11191 New functions, to expand SET_TYPE CONSTRUCTORs.
11192 * varasm.c (output_constructor): Use pack_set_constructor
11193 to assemble a SET_TYPE constant from a CONSTRUCTOR.
11195 * ch-grant.c (decode_constant): Better grant for strings,
11196 enumeral, and bitstring constants.
11197 * ch-grant.c: Fixes in seize to avoid duplicates, and emit
11198 things in the correct order.
11199 * c-typeck.c (chill_initializer_constant_valid_p): Kludge
11200 needed to export a static function.
11201 * ch-typeck.c (convert): Avoid needlessly (and lossingly) calling
11202 chill_expand_tuple to convert fix string to varying.
11203 * ch-actions.c (build_chill_binary_op): Promote short
11204 integer operands if needed (otherwise emit routines barf).
11205 * ch-tree.h (SET_WORD_SIZE): New macro.
11206 * ch-parse.y: Fix syntax for RECEIVE CASE.
11207 * ch-parse.y (location): If IDENTIFIER is a CONST_DECL
11208 return its value instead.

11227 * ch-expr.c, ch-loop.c, ch-process.c, ch-tree.c, ch-typeck.c: change
11228 most integer_type_node references to chill_integer_type_node.

11232 * ch-except.c: New file. Stuff for exception handling.
11233 * ch-parse.y: Add working exception handling support.
11234 * ch-lex.l, ch-parse.y: Prefer standard type terminology
11235 (BOOLS, CHARS) even though non-standard (BITS, CHAR) is ok.
11236 * ch-grant.c: Fix various problems related to granting
11237 types such as bitsets.
11238 * ch-tree.c (build_bitstring_type): Set TYPE_MIN_VALUE
11239 to distinguish bitstrings from powersets (in the same way
11240 we distinguish char strings from char arrays).
11241 * ch-tree.h: New macro CH_BOOL_TYPE_P.
11242 * ch-tree.h, ch-actions.c (lang_init), ch-grant.c (decode_mode):
11243 Undo kludge where integer_type_node was hardwired to 16 bits.
11244 Make integer_type_node etc have the same size as in cc1.
11245 New types chill_integer_type_node and chill_unsigned_type_node
11246 that correspond to the Chill source types INT and UINT.
11247 For now, these match the C 'short' types, but that should
11248 become a configuration option later,
11250 Tue Feb 9 11:41:25 1993 Bill Cox (bill@rtl.cygnus.com)
11252 * ch-actions.c (build_chill_unary_op): allow NOT of a set.
11254 Tue Feb 9 08:27:18 1993 Bill Cox (bill@rtl.cygnus.com)
11256 * ch-actions.c (build_chill_function_call): add test for
11257 too many/few actual parameters (and avoid seg fault).
11258 * ch-decl.c (do_decls): code cleanup for readability.
11259 * ch-loop.c (begin_chill_loop, end_chill_loop): remove
11260 emit_nop() calls - they now (since exceptions) cause seg faults.
11261 Make derogation on poor CHILL compiler non-specific.
11262 * ch-parse.y (mode2): enable VARYING keyword in CHAR(expr).
11263 * ch-tree.h: remove prototypes added to c-tree.h.
11264 * ch-typeck.c (build_chill_array_ref): correct getting domain
11265 subtree for a PARM_DECL. Subscripting a SET_TYPE is turned into
11266 an IN_EXPR.
11268 Sun Feb 7 18:20:49 1993 Bill Cox (bill@rtl.cygnus.com)
11270 * ch-tree.def: add a new tree type - just for varying array
11271 references. We were using ARRAY_REF, but the underlying C
11272 code also generates that one.
11273 * ch-convert.c, ch-expr.c, ch-typeck.c: use the new tree type.
11275 Sun Feb 7 17:33:17 1993 Bill Cox (bill@rtl.cygnus.com)
11277 * ch-convert.c: test given type against type of expr before
11278 calling chill_expand_tuple. We were getting lots of spurious
11279 calls...
11281 Fri Feb 5 15:24:01 1993 Per Bothner (bothner@rtl.cygnus.com)
11283 * cccp.c: Merge in various Chill-specific changes.
11284 * gcc.c (default_compilers array): Pass -lang-chill
11285 to cpp, not -lang-ch.
11287 Fri Jan 29 17:18:22 1993 Per Bothner (bothner@rtl.cygnus.com)
11289 * Makefile.in (install-libchill, install-librmt): Removed.
11290 * ch-actions.c (build_chill_exception_decl): Change decl
11291 to initialized char array, rather than uninitialized common.
11292 (Simplifies extracting string name of exception.)
11293 * ch-actions.c: Adjust interface to cause_exception accordingly.
11294 * ch-typeck.c (build_chill_array_ref): Cause rangefail if
11295 index > limit, not >= limit.
11297 * ch-actions.c (build_chill_function_call): Rename misleading
11298 formal parameter.
11299 * ch-decl.c (do_decls): Allow (again) general initializer exprs.
11300 * ch-parse.y (call): Test for function call needs to test for
11301 FUNCTION_TYPE, not FUNCTION_DECL.
11302 nreverse arg list to build_chill_array_ref.
11303 * ch-typeck.c (build_chill_array_ref): Do recursive call at end
11304 and only if multiple indexes.

11567 * chill.gperf, ch-hash.h: add Wilfried's tokens
11568 * ch-lex.l: fold in Wilfried's changes. Some tokens

11693 needed function.
11694 * ch-parse.y: Move code that is common to the beginning of

11737 * ch-hash.h, chill.gperf: cleanup. fewer keywords seen by ch-parse.y.
11739 Sat Jan 2 13:27:49 1993 Per Bothner (bothner@rtl.cygnus.com)
11741 * ch-lex.l (check_newline): Use the orginal versions (derived
11742 from the C code, not the simplified, special-case version).
11743 Also, fix that version of check_newline to not call yylex()
11744 recursively.
11745 * ch-lex.l (yy_input): Call check_newline to handle
11746 newlines and check for # directives.
11747 * ch-lex.l (syntax): Don't recognize #-directives; these
11748 are now handled by check_newline.
11749 * ch-actions.c (lang_init): Call the modified version of
11750 check_newline(). Do this at the *after* we've initialized
11751 standard types, so this can be done while lineno is still 0.
11753 Sat Jan 2 10:57:20 1993 Bill Cox (bill@cygnus.com)
11755 * ch-hash.h, chill.gperf: add remaining reserved words.
11757 Sat Jan 2 09:59:55 1993 Bill Cox (bill@cygnus.com)

11760 names for exceptions
11762 Fri Jan 1 12:30:31 1993 Fred Fish (fnf@cygnus.com)
11764 * ch-tree.h (JOINER): Define joiner character the same way
11765 C++ defines it.
11766 * ch-grant.c (chill_start_module_code): Use JOINER character
11767 to implement name mangling for the initializer function name.
11768 Algorithm is designed to be simple, distinct from C++ mangled
11769 symbols, and easy to convert to demangled form.
11771 Thu Dec 31 10:30:51 1992 Bill Cox (bill@rtl.cygnus.com)
11773 * ch-expr.c: make array assignments work with indirect refs.
11774 * ch-actions.c: prepare for array parameter handling.
11775 * ch-loop.c, ch-parse.y, ch-tree.def, ch-typeck.c: clean up.
11777 Thu Dec 31 15:29:20 1992 Per Bothner (bothner@rtl.cygnus.com)
11779 * ch-lex.l (yy_input): Re-write to return more than one
11780 character at a time (execpt when reading seize-files).
11781 Don't increment lineno until we start reading the next line.
11782 This fixes some off-by-one errors in lineno.
11784 Wed Dec 30 16:15:23 1992 Per Bothner (bothner@rtl.cygnus.com)
11786 * ch-convert.c: Assume use of new common.c.
11787 * ch-convert.c (convert_to_reference, convert_from_reference):
11788 New routines, to handle loc-identity declared variables and
11789 LOC parameters (both of which are implemented as references).
11790 * ch-lang.c (convert_to_boolean, convert_to_char): Move to
11791 ch-convert.c, where they would seem to belong.
11792 * ch-convert.c (convert): New function, since we no longer
11793 link in c-convert.c.
11794 * ch-expr.c (chill_expand_assignment): Handle by calling
11795 convert() instead of chill_comptypes().
11796 Also handle the LHS being a reference.
11797 * ch-parse.y: Add a procedure call as an action.
11798 * ch-parse.y (locdec, optlocinit): Move handling of
11799 loc-identity declarations from optlocinit to locdec
11800 - and add working semantics for it.
11801 * ch-parse.y (seizestatement, visibilty_stmt): Simplify.
11802 * ch-parse.y (grantstatement etc): Don't bother making list.
11803 * ch-lex.l: #include <sys/types.h> before <sys/stat.h>.
11805 Wed Dec 30 16:06:55 1992 Bill Cox (bill@rtl.cygnus.com)
11807 * ch-parse.y, ch-expr.c: add support for declaring & assigning
11808 VARYING arrays.
11809 * ch-typeck.c: allow VARYING structures in assign_type_to_expr.
11811 Tue Dec 29 15:28:48 1992 Bill Cox (bill@cygnus.com)
11813 * ch-actions.c: implement expressions of arrays of char,
11814 ( concatenation, relationals ), correct type of code parameters
11815 * ch-expr.c: correct type of code parameters
11817 Tue Dec 29 11:16:19 1992 Bill Cox (bill@cygnus.com)
11819 * ch-decl.c: cleanup.
11820 * ch-parse.y: put emit_line_note() calls in lotsa places,
11821 per Fred's request; be sure that statements get counted also.
11822 * ch-lex.l: standardize function headers.
11824 Tue Dec 29 10:41:56 1992 Fred Fish (fnf@cygnus.com)
11826 * ch-decl.c (start_chill_function): Always return 1, rather
11827 than a random value.
11828 * ch-lex.l (check_newline): Add a version for chill that
11829 just snarfs the right value for main_input_filename out of
11830 the first line of the input file, without disturbing the
11831 lexer state or requiring it's assistance.
11832 * ch-actions.c (lang_init): Call check_newline, like the
11833 other language frontends, to get main_input_filename set
11834 from first line of input file.
11836 Mon Dec 28 18:49:01 1992 Bill Cox (bill@cygnus.com)
11838 * ch-parse.y: clean up conflicts. The remaining one is
11839 harmless.
11841 Mon Dec 28 17:28:40 1992 Bill Cox (bill@cygnus.com)
11843 * ch-parse.y, ch-lex.l, ch-actions.c: add stubs for I/O,
11844 clean up some parser conflicts.
11846 Mon Dec 28 15:00:20 1992 Bill Cox (bill@cygnus.com)
11848 * ch-parse.y, ch-lex.l: add keywords and parsing for most of
11849 CHILL I/O
11851 Sat Dec 26 20:48:23 1992 Fred Fish (fnf@cygnus.com)
11853 * chillrt/chillrt0.c: Oops, SVR4 doesn't need leading '_'
11854 on build_exceptions.
11856 Sat Dec 26 11:00:36 1992 Fred Fish (fnf@cygnus.com)
11858 * ch-grant.c (chill_finish_module_code): Call
11859 assemble_constructor_alias rather than assemble_constructor.
11860 * varasm.c (assemble_constructor_alias): New function,
11861 like assemble_constructor, but also handles the case where
11862 ASM_OUTPUT_CONSTRUCTOR is not defined and GNU ld is not
11863 being used. Emits a symbol table alias name with the correct
11864 prefix for collect to find and add to the __CTOR_LIST__.
11865 * chillrt/chillrt0.c: Build on previous hack that gets
11866 _build_exceptions into the __CTOR_LIST__, to make it work
11867 for both the non GNU-ld case and for the SVR4 case.
11869 Tue Dec 22 18:24:55 1992 Bill Cox (bill@cygnus.com)
11871 * ch-loop.c: clean up location enumeration - one more
11872 pass to do.
11874 Tue Dec 22 16:31:48 1992 Bill Cox (bill@cygnus.com)
11876 * ch-loop.c: Working version of location enumeration loop
11878 Tue Dec 22 14:42:14 1992 Bill Cox (bill@cygnus.com)
11880 * ch-lex.l: readability cleanup
11882 Mon Dec 21 14:58:39 1992 Bill Cox (bill@cygnus.com)

11885 ch-loop.c: rough draft of location enumeration
11886 ch-lex.l, ch-expr.c, ch-decl.c: minor cleanup
11887 ch-actions.c: finish making pred() and succ() work.
11889 Mon Dec 21 10:04:35 1992 Bill Cox (bill@cygnus.com)
11891 * ch-actions.c: allow pred(char) and succ(char).
11893 Sun Dec 20 16:04:28 1992 Bill Cox (bill@cygnus.com)
11895 * ch-expr.c, ch-actions.c, ch-parse.y, ch-loop.c,
11896 c-expr.c: make DO WITH work.
11898 Sun Dec 20 12:22:53 1992 Bill Cox (bill@cygnus.com)
11900 * ch-loop.c, ch-actions.c, ch-typeck.c: powerset loops
11901 now work
11903 Sat Dec 19 14:20:23 1992 Per Bothner (bothner@cygnus.com)
11905 * c-typeck.c (process_init_constructor): Add warning if
11906 there is a duplicate default initializer element.
11907 * ch-typeck.c (chill_give_type_to_expr): New function,
11908 to handle coercion of an expression to context-given type,
11909 Takes care of untyped tuples, and case expressions.
11910 * ch-decl.c (do_decls), ch-typeck.c (chill_expand_return,
11911 chill_expand_result), ch-parse.y <assignaction>:
11912 Use chill_give_type_to_expr().
11913 * ch-typeck.c (chill_handle_case_label): New parameter list,
11914 to handle the (new) conventions for <case_label>, including
11915 default elements and ranges.
11916 * ch-parse.y <expanded_case_label>, ch-typeck.c
11917 (expand_case_expr): Use new version of chill_handle_case_label.
11918 * ch-decl.c (push_syndecls): Change parameters: Instead of
11919 TREE_LIST representing a compete <synonym definition statement>,
11920 just pass the parts of a single <synonym definition> as 3
11921 different parameters. Also, use chill_give_type_to_expr(),
11922 to handle untyped tuples in the RHS.
11923 * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct
11924 a tree - just call push_syndecls() on each <synonum_definition>
11925 as we see it.
11926 * ch-parse.y (exprlist_get_single): Remove; no longer needed.
11927 * ch-parse.y: Handle <tuple> without mode name diferently from
11928 <tuple> with mode name. The latter is a <primval> that can be
11929 in most contexts, but if the <mode name> is missing, the <tuple>
11930 is only allowed in certain contexts. Use the new non-terminal
11931 <untyped_expr> to indicate those contexts where untyped tuples
11932 (and case expressions) are valid because the expression gets a
11933 type from its context (such as the RHS of an assignment).
11934 Use chill_give_type_to_expr in those contexts.
11936 Sat Dec 19 14:01:26 1992 Bill Cox (bill@cygnus.com)
11938 * ch-actions.c, ch-loop.c, Makefile.in: looping stuff.
11940 Sat Dec 19 10:16:20 1992 Bill Cox (bill@cygnus.com)
11942 * ch-parse.y: clean up warning messages from byacc. bison
11943 still complains thrice.
11945 Fri Dec 18 12:33:29 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11947 * ch-actions.c (maybe_chill_comptypes): Delete unused
11948 function.
11949 (chill_comptypes): Add new parameter ERRSTR. All callers
11950 changed.
11951 (build_chill_binary_op): Fix indentation to match GNU coding
11952 style.
11954 Fri Dec 18 08:18:13 1992 Bill Cox (bill@rtl.cygnus.com)
11956 * ch-parse.y, ch-expr.c, ch-actions.c, expr.c: major

11966 a default initializer element.
11967 * ch-parse.y: Implement default elements for tuples
11968 (as in '(else):' and '(*):' ).
11970 * ch-parse.y: Previous change to dis-ambiguate case-labels
11971 seems to have allowed getting rid of all of the expr_or_list hair.
11972 * ch-decl.c (do_decls): Undo Tiemann's change to "Handle
11973 initialization of multiple variables by a tuple" - the
11974 idea is bogus.
11976 Wed Dec 16 11:17:53 1992 Bill Cox (bill@cygnus.com)
11978 * ch-parse.y: complete re-write of DO statement handling.
11979 now operational, except WITH is stubbed out. Improved
11980 syntax error message.
11981 * ch-actions.c: DO support: high_domain_value(), low_domain_value ().
11982 * ch-expr.c: fixes to IN_EXPR handling.
11984 Tue Dec 15 17:15:13 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11986 * ch-grant.c: Add casts to alloca return to avoid compiler warning.
11987 * ch-lex.c: Likewise.
11989 * Makefile.in (ch-lex.c): Delete incorrect free declaration added
11990 by flex to avoid compiler error.
11992 Tue Dec 15 08:41:08 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11994 * ch-decl.c (do_decls): Handle initialization of multiple
11995 variables by a tuple.
11997 * ch-decl.c (do_decls,start_chill_function): Make DECL public
11998 if we're doing a GRANT ALL at top level.
12000 * ch-lang.c (build_range_type): Deal with typecast to CHAR in
12001 range expression.
12003 * c-typeck.c (digest_init): SET_TYPE is not a scalar type.
12004 BOOLEAN_TYPE and CHAR_TYPE are scalar types.
12006 Mon Dec 14 14:58:32 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
12008 * ch-lex.l (get_chill_{linenumber,filename}): New functions.
12009 (convert_number): Use LONG_TYPE_NODE instead of INTEGER_TYPE_NODE.
12011 Mon Dec 14 13:36:44 1992 Bill Cox (bill@cygnus.com)
12013 * expr.c: install and test newer Pascal IN_EXPR code,
12014 but don't activate it - it's very verbose.
12016 Mon Dec 14 00:22:49 1992 Fred Fish (fnf@cygnus.com)
12018 * Makefile.in (LANGUAGES): Add chill.

12034 Sun Dec 13 14:07:32 1992 Bill Cox (bill@cygnus.com)
12036 * ch-actions.c: fix unary operations, modulus ops,
12037 (discovered after extending regression tests).
12039 Sun Dec 13 12:16:32 1992 Bill Cox (bill@cygnus.com)
12041 * resync with Michael and Wilfried
12043 Sun Dec 13 09:11:25 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
12045 * ch-parse.y (output_constant): Fixed some whitespace
12046 problems.
12047 * ch-tree.h: Add declarations for new chill functions that
12048 have been implemented but not (yet) declared.
12050 Sat Dec 12 00:17:23 1992 Per Bothner (bothner@cygnus.com)
12052 * c-typeck.c (process_init_constructor): Warn about duplicate
12053 labels for labelled initializer elements.
12054 * ch-lex.l (various operator tokens, such as "+"): Don't
12055 set yylval.code to a TREE_CODE; this is better done in parser.
12056 * ch-parse.y: Some work with case labels and tuples.
12057 Get literal range as tuple (and case) labels working.
12058 Fix some problems introduced by recent grammar overhaul.
12060 Fri Dec 11 13:28:48 1992 Bill Cox (bill@cygnus.com)
12062 * ch-actions.c, ch-parse.y ch-tree.h ch-expr.c, ch-typeck.c:
12063 got long, real expressions working. We can also call a func-
12064 tion and use its return value.
12066 Thu Dec 10 14:45:17 1992 Per Bothner (bothner@cygnus.com)
12068 * ch-parse.y: Major change to remove or at least identify
12069 parser ambiguities. One result: We now allow actions that
12070 start with '(', as required by teh Blue Book. This does break
12071 some things; look for FIXME for things that need work.
12072 * ch-typeck.c (chill_expand_case_expr): We need an extra
12073 level of looping to (in the future) support <case label
12074 specification>s with more than one <case label list>.
12076 Thu Dec 10 09:21:41 1992 Bill Cox (bill@cygnus.com)
12078 * ch-actions.c, ch-expr.c: Implement string assignments
12079 and relationals.

12087 * ch-parse.y, ch-actions.c, ch-expr.c: redo type checking.
12088 regression test and fix bit arrays and set ops.
12090 Mon Dec 7 14:57:46 1992 Bill Cox (bill@cygnus.com)
12092 * ch-actions.c: implement crude relationals between
12093 non-exotic operands, such as integers.
12095 Mon Dec 7 10:42:35 1992 Bill Cox (bill@cygnus.com)
12097 * ch-actions.c: implement relational, logic operations
12098 on arrays of BOOLs.
12100 Mon Dec 7 08:55:20 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
12102 * ch-actions.c (lang_init): Set LINENO to 1 at beginning to
12103 indicate we are done with initialization.
12105 * ch-decl.c (do_decls): Set TREE_PUBLIC if we are doing a
12106 `grant all'.
12107 (start_chill_function): Ditto.
12109 * ch-lex.c (convert_bitstring): Set TREE_CONSTANT.
12110 (compiler_directive): Don't confuse compiler directives with
12111 equality comparison operators.

12124 Fri Dec 4 13:54:58 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
12126 * tree.def: Move CARD_EXPR and SET_LE_EXPR back down with the other
12127 Pascal-required ones, since C++ no longer needs them. When
12128 Chill's public, a comment can be added to the effect that
12129 SET_LE_EXPR is also used by Chill.
12131 Fri Dec 4 12:05:01 1992 Bill Cox (bill@cygnus.com)
12133 * Restore CARD_EXPR and SET_LE_EXPR to tree.def.

12172 (push_newmode,push_synmode): Call `fixup_unknown_type' when we
12173 see a declaration that uses `unknown_type_node'. FIXME.
12175 * ch-grant.c (decode_constant): New function.
12176 (decode_decl): Call `decode_constant' for CONST_DECLs.
12178 * ch-lex.l (char action): Use ridpointers instead of
12179 lookup_name to get "char"'s declaration.
12181 * ch-parse.y: Call `build_lang_decl' instead of `build_decl'
12182 when we need to build a TYPE_DECL.
12184 Tue Dec 2 09:44:05 1992 Bill Cox (bill@cygnus.com)
12186 * ch-typeck.c: clean up a gcc warning with a forward
12187 declaration of build_string_type.
12189 Tue Dec 1 16:51:05 1992 Bill Cox (bill@cygnus.com)
12191 * ch-actions.c: completely remove those builtin calls
12192 that are duplicated in c-decl.c
12194 Tue Dec 1 16:38:51 1992 Fred Fish (fnf@cygnus.com)
12196 * ch-actions.c (lang_init): Ifdef out initializations for
12197 __builtin_abs and __builtin_fabs, since they are duplicates of
12198 initializations in c-decl.c, and trigger spurious warnings.
12200 Tue Dec 1 16:35:18 1992 Bill Cox (bill@cygnus.com)
12202 * ch-parse.y: make size() work with a typename argument.
12204 Tue Dec 1 16:15:56 1992 Bill Cox (bill@cygnus.com)
12206 * ch-parse.y, ch-lex.l, ch-actions.c: add builtin
12207 functions min, max, card.
12209 Tue Dec 1 12:35:56 1992 Bill Cox (bill@cygnus.com)
12211 * ch-lex.l: fix char-type
12213 Tue Dec 1 11:10:56 1992 Bill Cox (bill@cygnus.com)
12215 * ch-parse.y, ch-actions: added parsing and processing
12216 for upper, lower, and length built-ins.

12229 Mon Nov 30 17:35:33 1992 Fred Fish (fnf@cygnus.com)
12231 * chillsh: New script frontend (ala g++), installed as "chill".
12232 Can't be called "chill.sh" because make tries to cat it into the
12233 "chill" directory. Can't be called just "chill" cause that's
12234 already there as a directory.
12235 * Makefile.in: Add rules to install chillsh as "chill".
12236 * chill/libchill.c: Temporarily ifdef out stuff that wants
12237 to conflict with i486/SVR4 runtime or wants to pull in librmt.a,
12238 which itself causes linkage to fail.
12240 Mon Nov 30 16:28:19 1992 Bill Cox (bill@cygnus.com)
12242 * ch-lex.l: added keywords for TRUNC, ROUND, FLOAT, LFLOAT
12243 conversion routines.
12244 * ch-parse.y: added %tokens for TRUNC, ROUND, FLOAT, LFLOAT.
12245 Added production for SIZE(expr).
12246 * ch-actions.c: Add semantic routine chill_sizeof ().
12248 Mon Nov 30 16:20:40 1992 Per Bothner (bothner@cygnus.com)
12250 * ch-lex.l, ch-parse.y: Translate token PFEIL into English ARROW.
12251 * ch-parse.y (op6): Remove handling of string repetition operator,
12252 until we can figure out a way to parse it correctly.
12253 * ch-parse.y (optmodename): New non-terminal.
12254 * ch-parse.y (tuple): Merge the two variants using optmodename.
12255 * ch-parse.y (location): Add semantic actions for
12256 dereferencing operator ->.
12258 Mon Nov 30 08:01:29 1992 Bill Cox (bill@cygnus.com)
12260 * ch-actions.c: removed compile warning, better code for abs.
12262 * ch-parse.y: add productions for builtin functions succ, pred,
12263 abs, and size. Add %tokens also. Sort %tokens alphabetically.
12265 * ch-lex.l: add parsing for builtin function names, such as abs,
12266 pred, succ, etc. Put flex -a option into Makefile.in, so we can
12267 clean up the lexer soon.
12269 Tue Nov 24 14:18:48 1992 Per Bothner (bothner@rtl.cygnus.com)
12271 * ch-typeck.c (chill_handle_case_label, chill_handle_case_default):
12272 New functions, for code common to CASE actions and expressions.
12273 * chill.y: Replace some code by calls to chill_handle_case_label
12274 and chill_handle_case_default.
12275 * ch-typeck.c (chill_expand_case_expr): Add semantics.
12277 * tree.c: Change doing_chill_thang from extern to common.
12279 Mon Nov 23 18:34:22 1992 Per Bothner (bothner@rtl.cygnus.com)
12281 * ch-tree.def: New CASE_EXPR type, for case expressions.
12282 * ch-expr.c (chill_expand_expr): Hook for CASE_EXPR.
12283 * ch-typeck.c (chill_expand_case_expr): New function.
12284 Placeholder to implement case expressions.
12285 * ch-typeck.c (chill_expand_result, chill_expand_return):
12286 Handle mode-unspecified tuples and case expressions in
12287 the context of RETURN and RESULT actions.
12288 * chill.y (assignaction): Handle case expressions in the
12289 context of the RHS of an assignment action.
12290 * chill.y (caseaction): Remove spurious duplicate OF in grammar.
12291 * chill.y: Handle labeled structure tuples.
12292 * chill.y: New rules to parse CASE expressions.
12293 * tree.c (build_function_types): Allow Chill functions
12294 to return arrays and functions.
12296 Wed Nov 18 13:50:28 1992 Per Bothner (bothner@rtl.cygnus.com)
12298 * ch-typeck.c (chill_expand_tuple): New function. Expand a
12299 tuple (constructor) given an expected (context) type.
12300 * chill.y: Implement 'LHS := TUPLE' using expand_chill_tuple,
12301 using the mode of the LHS and the expected type of the TUPLE.
12302 * chill.y: Implement initialization.
12303 * chill.y: Fix some syntax bugs (forbidlist must be surrounded
12304 by parentheses), and remove or note ambiguities.
12305 * chill.y: Started converting layout style to be like c-parse.in.
12306 * chill.y: Implement IF expressions.
12307 * chill.y: Added syntax rules for tuples. Labelled and unlabelled
12308 array tuples should now work (in some contexts).
12309 * ch-actions.c: Initialize doing_chill_thang to 1.
12310 * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
12311 initializer, to make pushdecl and finish_decl work.
12312 * c-decl.c (convert_for_assignment): If Chill, don't convert
12313 function and arrays into pointers. (Maybe functions should
12314 still be converted?)
12315 * c-typeck.c (grokdeclarator): Allow functions in Chill
12316 to return arrays and functions.
12318 Mon Nov 16 15:40:47 1992 Per Bothner (bothner@rtl.cygnus.com)
12320 * chill.y (exprlist_get_single): New function, used when
12321 parsing tuples.
12322 * chill.y: Re-did parsing of tuples to remove ambiguities.
12323 This was a bitch.
12325 Tue Nov 10 16:30:55 1992 Per Bothner (bothner@rtl.cygnus.com)
12327 * ch-typeck.c (chill_expand_result); Set TREE_SIDE_EFEFCTS
12328 flags on assignment to result.
12329 * ch-typeck.c (build_chill_array_ref): Subtract lower
12330 bound of domain if non-zero. Preliminary hook for range checking.
12331 * ch-tree.h, chill.l: Combine variables range_check and
12332 range_check_disabled into global variable range_checking.
12333 * ch-tree.h: Better definitions of CH_CLASS_IS_VALUE
12334 CH_CLASS_IS_DERIVED.
