3331 bit-string, bit_one_node and bit_zero_node were switched.

3458 Wed Sep 21 00:54:21 1994 Per Bothner (bothner@kalessin.cygnus.com)
3460 Give up on trying to use the cleanup mechanism in stmt.c to
3461 make sure the exception handler get unlinked on goto/exit/return.
3462 Instead, do it ourselves. (Much simpler.)
3463 * except.c, ch-tree.h (action_nesting_level): New global.
3464 * ch-tree.h (DECL_ACTION_NESTING_LEVEL): New macro.
3465 * decl.c (define_label): Set DECL_ACTION_NESTING_LEVEL.

3504 * except.c (emit_setup_handler): Add a cleanup to
3505 unlink from exception stack if we return/exit/goto from here.
3506 * loop.c (begin_loop_scope): Move pushlevel from here ...
3507 * parse.c (parse_do_action): ... to here.

3525 * lex.l (readstring): Add processing of control sequence
3526 in character string literals. The granting mechanism writes
3527 this to grant files.

3531 * expr.c (compare_records): In case of -fpack do always
3532 a memcmp instead of comparing each field of the

3545 (add_taskstuff_to_list): Add a new argument, which is
3546 the entrypoint of a process.
3547 (build_process_header): Change PROCESS arguments to be
3548 like arguments of a function. There will be a wrapper
3549 which is the real entry point for a PROCESS. This wrapper
3550 is automatically build after a PROCESS definition and gets
3551 as argument a pointer to a structure looking like the
3552 arguments of the PROCESS. This wrapper will call the
3553 PROCESS (see build_process_wrapper).
3554 (build_process_wrapper): New function (see above).
3555 (build_start_process): Change processing of arguments.
3556 (tasking_setup): Add processing of a different entry point

3566 of PROCESSes, they look now like normal functions.
3568 * decl.c (init_decl_processing): Add declaration of memcmp

3576 version into grant file.
3578 * Make-lang.in (CHILL_FLAGS_TO_PASS): Add passing of CC and
3579 GNUCHILL_VERSION to ch/Makefile.
3580 * Make-lang.in (CHILL.mostlyclean): Add ch/ch-version.c.

3583 will get generated every time a new Makefile will get
3585 * Makefile.in (GNUCHILL_VERSION): Remove it, its defined in
3588 * chill.in: In case of -fgrant-only pass "-S -o /dev/null"
3589 to the compiler to avoid generation of an object file.
3591 Thu Sep 8 12:07:28 1994 Per Bothner (bothner@kalessin.cygnus.com)
3593 * convert.c (display_int_cst), ch-tree.h: New function.
3594 * convert.c (digest_array_tuple): Use digest_int_cst to
3595 provide better error messages. Return error_mark_node on error.
3596 * grant.c (decode_const): Simplify by using digest_int_cst.
3597 * grant.c (format_character, find_assoc): Removed.
3599 * decl.c (do_decl): Add missing TREE_CHAIN.
3601 * decl.c (finish_incomplete_decl): Removed.
3602 (init_decl_processing): Don't set incomplete_decl_finalize_hook.
3603 (finish_decl): Remove old C-specific code to deduce size of
3604 array from initialization.
3605 (complete_array_type): Just make it abort.
3607 * except.c (finish_handler_array): Avoid calling C-specific kludge
3608 complete_array_type.
3610 * convert.c (digest_constructor): Rename, and re-write to:
3611 (digest_array_tuple, convert): No longer use the code in
3612 ../c-typeck.c; use a Chill-only implementation (sigh).
3614 * typeck.c (chill_expand_tuple): Remove unneeded call to
3615 complete_array_type.
3617 * expr.c (fold_set_expr), grant.c (decode_constant),
3618 typeck.c (expand_constant_to_buffer): Update name of called
3619 function unpack_set_constructor to get_set_constructor_bits.
3620 * expr.c (powersetlen ): Remove redundant call to convert.
3622 * ch-tree.h (unpack_set_constructor): Removed obsolete declaration.
3624 * inout.c (build_chill_writetext): Handle 64-bit integer literals
3625 by trying to convert them to a smaller type.
3627 * lex.l (convert_number): Always use long long type (possibly
3628 unsigned) to avoid problems with constant folding truncation.
3630 Mon Sep 5 08:08:22 1994 Wilfried Moser (moser@rtl.cygnus.com)
3632 * ch-tree.h (enum chill_built_in_function): Add BUILT_IN_QUEUE_LENGTH.

3635 * expr.c (build_generalized_call): Add processing of
3636 BUILT_IN_QUEUE_LENGTH.
3638 * tasking.c (build_queue_length): New function.
3640 * tasking.c (tasking_init): Add new external function definition.
3642 Thu Sep 1 15:38:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3644 * lex.l (default_lex): New function. Progress towards
3645 getting rid of [f]lex.
3647 * lex.l (convert_number): Use mul_double and add_double.
3648 Set result type to a reasonable type in which the literal
3649 will fit. Give error message if literal is too big.
3651 * lex.l (equal_number): Switch (temporarily) to permanent obstack.
3653 * typeck.c (build_chill_slice_with_range): Check for empty
3654 slice *after* we have checked for upper/lower limit in range.
3656 * grant.c (decode_mode): Remove unused code. (BOOL and
3657 CHAR ranges are represented as INTEGER_TYPEs.)
3659 * tasking.c (build_process_header): Add missing call to
3660 expand_start_bindings.
3661 * parse.c (end_function): Add missing expand_end_bindings.
3663 Wed Aug 31 17:25:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3665 * decl.c (init_decl_processing): Set set_alignment.
3667 Tue Aug 30 16:40:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
3669 * actions.c (print_missing_cases, check_missing_cases,
3670 BITARRAY_TEST, BITARRAY_SET): New functions and macros,
3671 to check for completeness of case actions and expressions.
3672 * decl.c (c_decode_option, init_decl_processing):
3673 Don't set warn_switch.
3674 * expr.c (chill_expand_case_expr): Call check_missing_cases
3675 instead of check_for_full_enumeration_handling.
3676 * parse.c (parse_case_actions): Call check_missing_cases.
3678 * expr.c (build_chill_binary_op): Remove some dead code.
3679 * expr.c (chill_truthvalue_conversion): Call build_chill_binary_op
3680 instead of build_binary_op.
3681 * ch-tree.h (binary_op_error, build_binary_op): Unused. Removed.
3683 * parse.c (end_function): Use kept_level_p in parameter to
3684 poplevel. This reverts a June 13 change.
3686 Fri Aug 26 11:50:19 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3688 * configure: Ignore --without, as ../configure does.
3690 Wed Aug 24 01:17:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3692 * lex.l: Change rule for decimal numbers to allow identifiers
3693 to start with an underscore (_).
3695 Fri Aug 19 16:38:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
3697 * tasking.c (build_receive_signal_case_label): Remove backwards
3698 chill_convert_for_assignment (which converted whatever garbage
3699 was in the *target* to the type of the signal argument!).
3701 Fri Aug 19 07:10:43 1994 Wilfried Moser (moser@rtl.cygnus.com)
3703 * inout.c (build_chill_io_list_type, build_enum_tables),
3704 tasking.c (build_tasking_struct): Temporarily reset
3705 maximum_field_alignment to 0, so that the compiler-built
3706 data structures needed by the RTS can be independent of -fpack.
3708 Thu Aug 18 13:39:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3710 * typeck.c (build_init_struct): Temporarily reset
3711 maximum_field_alignment to 0, so that the compiler-built
3712 data structures needed by the RTS can be independent of -fpack.
3714 Wed Aug 17 23:48:33 1994 Wilfried Moser (moser@rtl.cygnus.com)
3716 * parse.c (parse_primval, expect, parse_on_exception_list):
3717 Print error message only in pass 2.
3719 Wed Aug 17 13:47:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3721 * decl.c (switch_to_pass_2): Revert June 13 change,
3722 (Don't exit after pass 1 if an error was found.)
3724 * ch-tree.def (SLICE_EXPR): New tree-code.
3725 * typeck.c (build_chill_slice): For building a slice of a
3726 bit-string, just generate a SLICE_EXPR.
3727 * decl.c (init_decl_processing): Declare __pscpy.
3728 * actions.c (chill_expand_assignment): Handle a SLICE_EXPR
3729 on the LHS of assignment, by calling __pscpy.
3730 * expr.c (chill_expand_expr): Handle SLICE_EXPR (as a RHS
3731 value) by using __psslice to copy slice to a temp.
3733 Wed Aug 17 05:52:44 1994 Wilfried Moser (moser@rtl.cygnus.com)
3735 * Make-lang.in: Change version of GNUCHILL compiler to 1.4.1.
3736 * expr.c (build_chill_length): Enable LENGTH built-in to process
3737 Buffers and Events too (Z.200/1992).
3738 * lex.l (yywrap): Always set yyin to finput and/or grt_in. On
3739 a linux system the previous version was not able to run.
3740 * tasking.c: Correct processing of infinite buffer- and event-length
3741 to avoid RANGEFAIL warning.
3743 Thu Aug 11 11:46:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3745 * parse.c (parse_if_expression_body): Don't call the C-specific
3746 build_conditional_expr. Just do build_nt (COND_EXPR, ...).
3747 * convert.c (convert): Convert a COND_EXPR by converting
3750 * convert.c (convert): Don't call convert before
3751 convert_to_reference. It's apt to do weird and unneedful things.
3752 * convert.c (convert): If the expression is varying, just call
3753 varying_to_slice, which simplifies quite a bit.
3755 * ch-tree.h (varying_to_slice): Add prototype.
3756 * typeck.c (varying_to_slice): Remove prototype.
3758 * satisfy.c (satisfy): Move case PAREN_EXPR from type 'e'
3761 * except.c (emit_setup_handler): Temporarily reset the
3762 maximum_field_alignment to zero so the compiler's exception
3763 data structures can be compatible with the run-time system,
3764 even when we're compiling with -fpack.
3766 * expr.c (compare_records): Call saved_if_needed on operands.
3768 * expr.c (build_set_expr case NE_EXPR): Don't use __nepowerset
3769 which has been reimplemented to just call __eqpowerset and
3770 invert the result. Inline this new implementation by
3771 handling as EQ_EXPR, and inverting the result.
3772 * decl.c (init_decl_processing): Don't define unused __eqpowerset.
3774 * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
3775 type boolean_type_node, not void_type_node. (Fixing this
3776 avoids a crash in the back-end.)
3778 * grant.c (decode_constant): In a CALL_EXPR, if the argument
3779 list is not a TREE_LIST (as in string repetiation), don't
3782 Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3784 * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
3785 CONST_DECL is from a SET definition. (This is safer than
3786 checking that the type is ENUMERAL_TYPE, because synonym
3787 definitions may have a NULL TREE_TYPE.)
3788 Also, if we have duplicate enums whose types are identical,
3790 * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
3791 an extra 'quiet' parameter, which is true if we're called from
3792 bind_sub_modules. (In that case an error message about duplicated
3793 decls would be repeated later, so suppress it.)
3795 * parse.c (stmt_count): Removed, not used.
3796 (INIT_ACTION): Call emit_line_note only if !ignoring.
3797 (parse_begin_end_block): Do INIT_ACTION even if ignoring.
3799 Fri Aug 5 12:39:11 1994 Per Bothner (bothner@kalessin.cygnus.com)
3801 * parse.c (parse_untyped_expr): Add missing semi-colon.
3803 Thu Aug 4 17:40:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
3805 * parse.c (parse_untyped_expr): Fix various problem for the
3806 case that we see a '(': Add missing 'case' keyword.
3807 Only recurse if '(' is followed by 'if', 'case' or '[',
3808 and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
3810 * parse.c (parse_send_action): Remove extra nreverse.
3812 Thu Jul 28 04:00:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3814 * expr.c (build_allocate_global_memory_call, build_allocate_memory_call):
3817 Tue Jul 26 22:48:15 1994 Michael Tiemann (tiemann@blues.cygnus.com)
3819 * parse.c (parse_untyped_expr): Added missing "case" before LPRN.
3820 Added a missing call to `require' as well.
3822 Tue Jul 19 10:30:12 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3824 * lex.l (yywrap): Define as yywrap_chill to avoid conflicts with
3825 the extern declaration in the flex skeleton.
3827 Mon Jul 18 23:06:04 1994 Per Bothner (bothner@kalessin.cygnus.com)
3829 * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
3830 Check the type of the instance expr using CH_COMPATIBLE,
3831 and not just == instance_type_node. (This allows
3832 the expression to have mode READ INSTANCE).
3833 * tasking.c (build_instance_type): Give instance_type_node
3834 a non-null novelty (i.e. different from a struct).
3835 * tasking.c (build_receive_case_start, build_delay_case_start):
3836 Check that for a location using CH_LOCATION_P.
3838 Mon Jul 18 13:22:23 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
3840 * expr.c (finish_chill_unary_op): Use TREE_SET_CODE not TREE_CODE
3841 to modify a tree code.
3843 Mon Jul 18 11:24:57 1994 Bill Cox (bill@rtl.cygnus.com)
3845 * convert.c (digest_structure_tuple): Fix thinko in TREE_CODE
3848 Mon Jul 18 05:40:15 1994 Doug Evans (dje@canuck.cygnus.com)
3850 * decl.c (warn_bad_function_cast): Define so cc1chill will link.
3852 Thu Jul 14 18:37:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3854 * parse.c (parse_send_action): Do tree_cons *before* checking
3857 Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3859 * convert.c (digest_structure_tuple): Don't use convert to
3860 coerce initial value, use chill_convert_for_assignment instead.
3861 (Thus we also get range_checking.)
3863 * expr.c (build_chill_card): Use force_addr_of instead of
3864 build_chill_addr_expr.
3866 * loop.c (build_temporary_variable): Stylistic tweak.
3867 * loop.c (maybe_make_for_temp): Initialize temp using
3868 explicitly, not using assignment. Avoids a problem if
3869 the expression is read-only.
3870 * typeck.c (smash_dummy_type): Always used the saved TYPE_NAME
3871 and CH_NOVELTY_FLAG.
3873 Wed Jul 6 20:12:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3875 * expr.c, ch-tree.h (finish_chill_unary_op): New function,
3876 based on code ripped out of build_chill_unary_op.
3877 (build_chill_unary_op): Call finish_chill_unary_op unless pass==1.
3878 * satisfy.c (satisfy): Call finish_chill_unary_op when needed.
3880 Mon Jun 27 11:29:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3882 * tree.c (save_if_needed), ch-tree.h: New function.
3883 * typeck.c (build_chill_slice_with_range,
3884 build_chill_slice_with_length): Call save_if_neeed on array arg.
3885 * expr.c (varying_to_slice): Re-write to use save_if_needed.
3887 * typeck.c (extract_constant_from_buffer): Handle BOOLEAN_TYPE.
3889 Mon Jun 27 01:11:10 1994 Wilfried Moser (moser@rtl.cygnus.com)
3891 * inout.c (build_chill_io_list_type): Change layout of __tmp_WIO_list
3892 that it is always the same, regardless if compiled with -fpack
3895 Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3897 * lex.l (yywrap): Kludge to work around mis-synchronization
3898 between lexer (which read ahead) and parser: Don't emit
3899 (left-over) uze_seizefile directives at the end of file.
3901 * typeck.c (build_chill_array_ref): Allow the derived
3902 array indexing syntax for arrays of bit strings.
3903 Add a comment explaining why.
3905 * typeck.c, ch-tree.h (string_assignment_condition): Change
3906 the interface. Return a boolean expression (which can be
3907 used in a conditional at run-time); never expand anything.
3909 * actions.c (chill_convert_for_assignment): Check
3910 string_assignment_condition here, rather than in callers.
3911 * actions.c (chill_expand_assignment): Don't need to check
3912 string_assignment_condition here.
3913 * expr.c (build_chill_function_call): Likewise.
3914 * satisfy.c (safe_satisfy_decl): Update accordingly.
3915 * decl.c (do_decl): Simplify testing and conversion by
3916 deferring everything to chill_convert_for_assignment.
3918 * parse.c: Combine the two variables 'ignore_exprs' and
3919 'ignore_actions' into one variable called 'ignoring'.
3920 * ch-tree.h: Add 'extern int ignoring'.
3921 * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
3922 Rename ignore_actions and ignore_exprs to ignoring.
3923 Remove unneeded extern declarations.
3924 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3925 build_chill_arrow_expr, build_generalized_call, build_delay_action,
3926 build_buffer_type, build_event_type): I changed my mind. It is
3927 cleaner to check for 'ignoring' in the parser, rather than here.
3928 * parse.c (parse_action, parse_primval, parse_opt_mode):
3929 Therefore we must check for ignoring here.
3930 * parse.c (parse_loc_declaration): Set ignoring in pass 2
3931 when parsing the mode.
3933 * tasking.c (generate_tasking_code_variable): Do arithmetic
3934 on signal_code etc using unsigned rather than signed shorts.
3936 * grant.c (static char* current_grant_modename): Removed.
3937 * grant.c (decode_decl case CONST_DECL): Remove error message.
3939 * Make-lang.in (CHILL_SRCS): Add $(srcdir)/ch/parse.c.
3940 * Makefile.in: Fix dependencies for parse.o.
3941 Remove some duplicate dependencies for $(TREE_H).
3943 Mon Jun 13 14:25:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3945 * typeck.c (build_chill_cast): Allow a value cast between
3946 non-discrete object of the same size, but with a pedwarn.
3947 * typeck.c (bit_string_assignment_condition,
3948 char_string_assignment_condition): Merge near-duplicate functions
3949 and place the code in string_assignment_condition.
3951 * decl.c (parm_flag, declare_parm_level, in_param_level_p):
3953 * decl.c (start_chill_function, finish_chill_function): Make
3954 parameter level have same nesting level as body, as required by Z200.
3955 * decl.c (switch_to_pass_2): Always exit if an error has been found.
3956 * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
3957 generated from GRANT ALL.
3958 * decl.c (lookup_name_for_seizing): Don't seize from
3959 the nesting level of builtins (predefined objects).
3960 * decl.c (lookup_name_for_seizing): Make more robust on error.
3962 * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
3963 be 'RESULT' (or 'result'). This makes it more accessible from gdb.
3964 Also, use do_decl to declare it, so that debugging symbols are
3965 generated. And, re-arrange so that actions that need to
3966 be done both passes (such as push_levels) use the same code.
3968 * parse.c (get_type_of): If ignore_exprs, don't lookup name.
3969 * parse.c (end_function): Fix poplevel params.
3970 * parse.c (expect): Don't read forwards on an error.
3971 * parse.c (parse_field): Don't define two tag_list locals!
3972 * parse.c (parse_pass_1_2): Better error message.
3974 * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
3975 parse_opt_mode, rather than vice versa. If parse_opt_mode
3976 returns NULL_EXPR, then parse_mode gives an error.
3977 Change parse_opt_mode (and any functions it calls) to only
3978 return NULL_TREE if there is no mode (even on ignore_exprs).
3979 (parse_set_mode, parse_structure_mode, parse_procedure_mode):
3980 Never return NULL_EXPR.
3981 * tasking.c (build_buffer_type, build_event_type): Return
3982 void_type_node instead of NULL_EXPR if ignore_exprs is true.
3984 * parse.c (parse_synonym_definition): Call parse_untyped_expr
3985 only if we have a mode.
3986 * parse.c (parse_send_action): Parse list of untyped_expr's,
3987 rather than a list of (typed) expressions.
3988 * parse.c (parse_primval): Emit error if '[' seen without
3989 preceding mode name. (If this is to be allowed, call
3990 parse_untyped_expr instead.)
3992 * parse.c (parse_array_index): Renamed to ...
3993 (parse_index_mode): ... to match Z200 terminology.
3994 Re-write to resolve some of the nastier ambiguities,
3995 and allow things like ' CHAR(10) : CHAR(20) '.
3997 * parse.c (parse_tuple_element): Change interface to return
3998 reversed list, so don't call nreverse.
3999 * parse.c (parse_tuple): No longer nreverse element list here.
4000 * parse.c (parse_opt_element_list): Do nreverse here instead.
4001 * parse.c (parse_case_label_list): Call nreverse at end.
4003 Fri Jun 10 15:36:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
4005 * typeck.c (chill_similar): Remove bogus "else".
4007 Wed Jun 8 00:01:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
4009 * ch-tree.h (TYPE_ARRAY_MAX_SIZE): New macro (and comment)
4010 to make it clearer that we are using TYPE_MAX_VALUE in a special way.
4011 * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
4012 * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
4013 * convert.c (convert): When converting a fixed string/array
4014 to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
4015 of (the type of) the padding.
4016 * convert.c (convert): If the concatenation is non-constant, use
4017 the low-level 'build' to set the type of the result (which is usually
4018 a fixed-size array) rather than depend on build_chill_binary_op
4019 to figure it out (it's unable to simplify the size to a constant).
4021 Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
4023 * lang.c (lang_decode_option): Let -fspecial_UC imply
4024 -fno-ignore-case without requiring it explicitly.
4025 * lang.c (lang_decode_option): Support (experimentally)
4026 the -fpack and -fno-pack flags.
4028 Thu Jun 2 20:49:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4030 * configure: Add support for --program-prefix and --program-suffix.
4032 Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
4034 * convert.c (digest_constructor): Check that initial value
4035 is compatible with element mode before calling convert.
4036 * typeck.c (chill_compatible): A string mode is not compatible
4037 with an untyped constructor.
4038 * decl.c (do_decl): Clean up error messages. Use error_with_decl.
4040 * ch-tree.h: Fix inconsistencies: bool_true_node ->
4041 boolean_true_node, and bool_false_node -> boolean_false_node.
4042 * typeck.c (valid_array_index_): Minor simplification.
4044 Tue May 31 04:33:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
4046 * inout.c (build_chill_writetext): Add correct processing
4047 of POWERSET RANGE (setmode).
4049 * lex.l (same_file): Add searching for file(s) in
4052 Fri May 27 14:22:42 1994 Per Bothner (bothner@kalessin.cygnus.com)
4054 * Make-lang.c (CHILL.mostlyclean, CHILL.distdir): Don't list
4055 yacc/bison output files, since the grammer is no longer in yacc.
4056 * config-lang.in (diff_excludes): Likewise.
4058 Thu May 26 16:38:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
4060 * gperf, hash.h, lex.l, parse.h: Rename PROCESS_TYPE token
4061 (in some files spelled PROCESS_TYPE_ to avoid clashes
4062 with the PROCESS_TYPE tree_code) to PROCESS_TYPE_TOKEN.
4064 Thu May 26 02:18:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
4066 * timing.c (build_cycle_start): Change call to __define_timeout.
4067 * decl.c (init_decl_processing): Change definitions of
4068 __define_timeout and __wait_timeout.
4070 Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
4072 Replace yacc-based parser with a recursive-decent parser.
4073 (This may seem backwards, but Chill [like C++] is not a
4074 language that is remotely LALR(1). Using a R-D parser
4075 allows us to use look-ahead and to back-up to resolve the
4076 difficult ambiguities.)
4078 * parse.c, parse.h: New files, containing new r-d parser.
4079 * Makefile.in: Update accordingly.
4080 * actions.c (chill_convert_for_assignment): Don't return
4081 NULL_EXPR if ignore_exprs is true. It simplifies the parser
4082 if we consistently reserve NULL_EXPR for a missing expression.
4083 * expr.c (build_chill_function_call): Likewise.
4085 * lex.l: Tweaks for new parser.
4086 * lex.l (prepare_paren_colon, paren_paren_colon_level,
4087 paren_level): Ugly hack no longer needed.
4089 * expr.c (build_chill_function_call): Cleanup.
4090 Call chill_convert_for_assignment to convert IN/INOUT
4091 paramaters on both input and output. For LOC parameters,
4092 give error if actual is a non-referable location.
4093 * actions.c (convert_for_assignment): Add new parameter (a
4094 "place" string used in error messages).
4095 * actions.c (adjust_parm_or_field): Removed.
4096 * actions.c (chill_expand_assignment): Take just a single LHS,
4097 and move support for multiple assignments to ...
4098 (expand_assignment_action): ... here. Some cleaning up.
4099 * timing.c (build_cycle_start): Adjust accordingly.
4100 * actions.c (expand_assignment_to_varying_array): Likewise.
4101 * tasking.c (many places): Ditto.
4102 * ch-tree.h: Fix declarations appropriately.
4104 * parse.c (parse_defining_occurrence_list): Return a single
4105 IDENTIFIER_NODE (instead of a singleton list) in the common
4106 case. Minor complication to save a minor amount of space.
4107 * decl.c (do_based_decls): Move guts of code into ...
4108 (do_based_decl): ... this new function.
4109 * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
4110 * decl.c (push_syndecl): Replace by ...
4111 (push_syndecl): ... (which only supports a single name).
4112 (push_modedef): Only handle a single name.
4113 * tasking.c (build_process_header, build_signal_struct_type):
4116 * expr.c (build_generalized_call): Handle string repetition.
4117 * expr.c (build_chill_repetition_op): Change interface.
4118 * grant.c (decode_constant): Allow parameter list to be
4119 a non-TREE_LIST. (Used for string repetition.)
4121 Wed May 25 11:28:48 1994 Per Bothner (bothner@kalessin.cygnus.com)
4123 * lex.l (make_identifier): Replaced by ...
4124 (read_identifier, handle_name): ... new functions.
4125 * lex.l: Parse an identifiers using read_identifier using
4126 read_identifier and handle_name, rather than having [f]lex
4127 do it. (One reason is that lex uses a fixed-size buffer.)
4129 * lex.l (read_directive, skip_directive): New functions.
4130 Use them to parse compiler-directives, instead of rather
4131 ugly and useless use of lexer start conditions.
4133 Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4135 * decl.c (unnamed_module_number): Renamed to ...
4136 (module_number): .. and make non-static.
4137 (push_module): Always increment module_number.
4138 * lex.l (yywrap): Print warning if no modules seen.
4140 * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
4141 decl to current_seizefile_name (which is unreliable).
4142 * grant.c (chill_grant): Set it here instead.
4144 * expr.c (fold_set_expr): Use int_size_in_bytes instead of
4145 TYPE_PRECISION (which is not defined for a SET_TYPE).
4147 Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
4149 Cleanup to remove need for variables in common storage.
4150 * decl.c: Remove unused use of current_obstack.
4151 * actions.c (maybe_chill_check_decl): Remove unused function.
4152 * actions.h, lang.c: Remove uses of doing_chill_thang.
4153 * ch-tree.h (void_list_node): Make extern (rather than common).
4154 * decl.c (void_list_node): Add definition.
4156 Thu May 19 06:54:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
4158 * configure (build): Build canon_host and canon_target
4159 to pass it to all subsequently generated Makefiles (needed
4160 for testsuite/execute in case of cross build).
4162 Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4164 * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
4165 the input type, which loses with the no-longer-new 2-pass
4166 implementation, since the input "type" could be an IDENTIFIER_NODE.
4167 * grant.c (raw_decode_mode): Rename to decode_mode.
4169 Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
4171 * typeck.c (chill_location): Neither a STRING_CST nor a
4172 CONSTRUCTOR is a location.
4173 * typeck.c (chill_root_mode): Convert a function to a
4174 pointer-to-function.
4175 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
4176 build_chill_arrow_expr): If ignore_exprs, return operand
4177 rather than NULL_EXPR. This makes it easier for the parser to
4178 distinguish missing expressions.
4179 * expr.c (build_max_min): Convert the lower bound of a
4180 set to a long before calling run-time routine.
4181 * expr.c (build_chill_pred_or_succ): Use discrete_type_p
4182 to check the argument type.
4183 * expr.c (build_chill_arrow_expr): If argument is not a location,
4184 do a predwarn if it is a STRING_CST or has function type.
4186 Tue May 17 06:05:13 1994 Wilfried Moser (moser@rtl.cygnus.com)
4188 * configure (build): Remove building of canon_host and canon_target.
4189 It doesn't work in any case.
4191 Mon May 16 02:10:35 1994 Wilfried Moser (moser@rtl.cygnus.com)
4193 * configure (build): Build canon_host and canon_target
4194 to pass it to all subsequently generated Makefiles (needed
4195 for testsuite/execute in case of cross build).
4196 * Make-lang.in (chill-runtime): Change chill to CHILL in the case
4197 statement to build chill-runtime automatically.
4199 Mon May 9 15:30:08 1994 Doug Evans (dje@canuck.cygnus.com)
4201 * Makefile.in (FLAGS_TO_PASS): Define.
4203 (../cc1chill): Depend on $(OBJDEPS) $(C_OBJS).
4204 * Make-lang.in (cc1chill): Delete dependency on $(OBJS) $(BC_OBJS).
4205 (CHILL.mostlyclean): Use `mostlyclean' as recursive target.
4207 Sun May 8 13:05:00 1994 Per Bothner (bothner@cygnus.com)
4209 * Make-lang.in (cc1chill): Should not depend on libgcc.a.
4211 Thu May 5 18:58:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
4213 * decl.c (copy_lang_decl): New (dummy) function.
4215 Mon May 2 14:33:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
4217 * parse.y (sendaction): Fix thinko (in sense of condition).
4218 * tasking.c (build_receive_case_label): Another thinko.
4220 * parse.y (optsigdest): Force ignore_exprs to 0 while parsing
4223 * decl.c (build_chill_function_type): Don't call layout_type
4224 (since that may prevent parameter or result types being
4225 properly satisfied).
4226 * satisfy.c (satisfy): Layout FUNCTION_TYPEs.
4227 * parse.y (procmode): Call build_chill_pointer_type, rather
4228 than build_pointer_type (which incorrectly sets TYPE_SIZE).
4230 * parse.y (get_type_of): Handle TYPE_DECL (again).
4231 * parse.y (optresultspec): Call build_chill_reference_type, rather
4232 than build_reference_type (which incorrectly sets TYPE_SIZE).
4233 * parse.y (range_or_mode): Rename to plain range, since it
4234 no longer matches modename.
4235 * actions.c (chill_handle_case_label_range): New function, with
4236 functionality moved out of chill_handle_case_label.
4237 * actions.c (chill_handle_case_label): Handle here the case that
4238 the label_value is a TYPE_DECL (modename). Also clean up some.
4239 * typeck.c (build_chill_slice_with_length): Convert max_index
4240 to the type of min_value. (Old code broke on varying strings.)
4242 Sun May 1 13:53:36 1994 Doug Evans (dje@canuck.cygnus.com)
4244 * Makefile.in (BC_OBJS): Delete all references
4245 (OBJS): Cat ../stamp-objlist to get language independent files.
4246 (../cc1chill): Delete dependency on $(OBJS).
4247 * Make-lang.in (cc1chill): Depend on stamp-objlist.
4249 Sat Apr 30 14:50:15 1994 Per Bothner (bothner@kalessin.cygnus.com)
4251 * lex.h, lex.c: Remove lastiddecl.
4252 * lex.l (name_type_signal): Simplify. We no longer check for
4253 TYPENAME or SIGNALNAME (which was unreliable with two passes).
4254 Also rename to make_identifier.
4255 * parse.y: Cleaned up grammar to not need SIGNALNAME or TYPENAME.
4256 * Makefile.in (stamp-parse); One conflict fewer!
4257 * parse.y (rccase_label_flag): Moved to tasking.c.
4258 * parse.y (rccase_label): Move most of the logic to
4259 build_receive_case_label in tasking.c.
4260 * parse.y (sendaction): Re-write to not depend on SIGNALNAME.
4262 * parse.y (name): Do name lookup here (and not in location).
4263 * parse.y: Replace most uses of NAME by higher-level non-terminals:
4264 simple_name_string, name_string, defining_occurrence, or name.
4266 * tasking.c (build_receive_signal_case_label,
4267 build_receive_buffer_case_label): New functions, split out from
4268 build_receive_case_label.
4269 * tasking.c (build_receive_case_label): Change parameters
4270 and return type. Moved stuff here (from the parser).
4271 * tasking.c (struct rc_state_type): Removed had_errors.
4272 Return error_mark_node instead.
4273 * tasking.c (build_rccase_set_error), ch-tree.h: Removed.
4275 * expr.c (build_generalized_call): If func is a signal type,
4276 call build_signal_descriptor.
4278 * parse.y (arrayindex): Renamed to index_mode, to match Z.200.
4279 * parse.y (ioindexmode): Removed; use index_mode instead.
4280 * expr.c (build_generalized_call): If args is a RANGE_EXPR,
4281 we have either a slice or a range mode, depending on func.
4282 * parse.y (index_mode): If we got an 'expr', only allow a name,
4284 * parse.y (call): A slice with both end points can be a range
4285 mode, so defer handling to build_generalized_call (or index_mode).
4287 * typeck.c (build_chill_slice_with_length): Fix type-checking.
4288 * typeck.c (chill_novelty): Undo (part of) change of April 28:
4289 The novelty of a range mode is the novlety of the parent.
4290 * typeck.c (chill_root_mode): Don't return integer_type_node
4291 if argument has non-nil novelty.
4293 * decl.c (global_bindings_p): Return -1 as true, for the sake
4294 of variable_size (in ../stor-layout.c).
4296 Fri Apr 29 13:42:43 1994 Per Bothner (bothner@kalessin.cygnus.com)
4298 * parse.y: Remove TYPENAME and modename. These are now plain
4299 NAMEs. Modify parsing actions appropriately.
4300 * expr.c (build_generalized_call): Handle the case that
4301 TREE_CODE (func) == TYPE_DECL (as in a cast).
4302 * lex.l (name_type_signal): Never return TYPENAME.
4303 * parse.y (get_type_of): If pass 1, just return the argument.
4305 * decl.c (do_decl): If an initializer has the wrong type,
4306 replace it by NULL_TREE, to avoid subsequent errors.
4308 Thu Apr 28 15:21:56 1994 Wilfried Moser (moser@rtl.cygnus.com)

4350 Thu Apr 28 14:11:29 1994 Per Bothner (bothner@kalessin.cygnus.com)
4352 * typeck.c (smash_dummy_type): Handle the special case of a
4353 NEWMODE of a range mode, as required by Z200, by creating a
4354 new parent mode with the new novelty (and casting the min
4355 and max of the range to teh new parent mode).
4356 * typeck.c (chill_novelty, chill_root_mode): Remove special
4357 kludges for of NEWMODE ranges.
4358 * expr.c (build_chill_lower_or_upper): New function, combining
4359 the "guts" of build_chill_lower and build_chill_upper.
4360 * expr.c (build_chill_lower_or_upper): Simplify; no longer
4361 need to kludge the novelties.
4363 * typeck.c (valid_array_index_p): A string index expression
4364 need not be Compatible with the index type; only similar.
4366 * decl.c (layout_chill_variants): If error seen, skip stuff
4367 (rather than aborting or crashing).
4368 * decl (push_modedef): If newdecl's type is an error mark,
4369 continue rather than aborting.
4371 Thu Apr 28 02:07:42 1994 Doug Evans (dje@cygnus.com)
4373 * Make-lang.in: Update of directory reorg from fsf.
4374 * config-lang.in: Ditto.
4376 Mon Apr 25 13:09:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
4378 * typeck.c (chill_similar): Check RECORD_TYPEs properly,
4379 * convert.c (convert): If all else fails, just call convert1.
4380 Thus we can now convert RECORD_TYPEs (assuming they are similar).
4382 * parse.y, lex.l: Remove BUFFERNAME (use location/expr instead).
4383 * parse.y: Re-do BUFFER handling (similar to previous EVENT change).
4384 * grant.c (raw_decode_mode): Re-do BUFFER mode handling.
4385 * ch-tree (lang_type_record): Removed max_queue_size field.
4386 * tasking.c (build_buffer_type): Re-write.

4391 to name and simple_name_string. This removes a reduce/reduce conflict.
4392 * Makefile.in (stamp-parse): Expect fewer conlicts.
4394 * lex.l (yywrap): Move check for circularly seizeing current
4395 grant-file from here ...
4396 * lex.l (handle_use_seizefile_directive): ... to here.
4397 This is to avoid calling stat on a not-yet written grantfile,
4398 now that we're using same_file (which calls stat).
4399 * grant.c (set_use_this_gf): Removed.
4400 * grant.c (set_default_grant_file): Set grant_file_name here,
4401 because we need it earlier (due to above lexer change).
4403 * typeck.c (layout_chill_struct_type): Remove useless code to
4404 remove zero-width bitfield (which messes up CONST_DECLs).
4406 Sat Apr 23 13:16:39 1994 Bill Cox (bill@rtl.cygnus.com)
4408 * Makefile.in (check): Assure that 'ld' is available before checking.

4413 (raw_decode_mode): Generalized to use decode_constant
4414 instead of print_an_int.
4415 (decode_constant): Print directly, instead of calling print_an_int.
4416 * parse.y (event_list): Fix syntax.
4417 * parse.y (optqueuesize): Default is NULL_TREE, not zero.

4419 * ch-tree.h: Add declaration for check_queue_size.
4420 * satisfy.c (satisfy case RECORD_TYPE): Satisfy constant fields
4421 (used for queue size of EVENT and BUFFER), and call check_queue_size.

4425 Re-implement EVENT modes to support general EVENT objects
4426 (and not just EVENT names), according to Z200. (Not finished!)
4427 * tasking.c, ch-tree.h (max_queue_size): New function.
4428 * parse.y (dcalternative, event_list, event_list_head): New
4429 implementation of DELAY CASE, avoiding parsing ambiguities.
4430 (call, locdec, delayaction): Remove old EVENTNAME kludges.
4431 * lex.l (name_type_signal): Remove EVENTNAME recognition.
4432 * tasking.c (build_event_type): Re-written.

4435 * typeck.c (layout_chill_struct_size): Ignore CONST_DECL.
4436 * tasking.c (build_delay_action): Preliminary changes - just to
4437 make it compile. FIXME!
4438 * grant.c (raw_decode_mode): Use new max_queue_size function.
4439 Move EVENT support from LANG_TYPE to RECORD_TYPE.
4440 * ch-tree.h (process_event_decls): Removed.
4442 Tue Apr 19 11:44:01 1994 Bill Cox (bill@rtl.cygnus.com)
4444 * regression.sh: Complete previous change - eliminate all
4445 references to objdir as a user parameter.
4447 Mon Apr 18 10:17:55 1994 Bill Cox (bill@cygnus.com)
4449 * Makefile.in (check): Simplified regression.sh call.
4450 * regression.sh: Change command-line parsing. Default
4451 srcdir to the script's path. Calculate objdir
4452 internally - don't pass it in.

4476 * lex.l (chill_same_grant_file): Rename to same_file. Change to
4477 take two files names rather than two DECLs. Also check that the
4478 filesystems (st_dev) are equal. Finally, make static.
4479 * lex.l (handle_use_seizefile_directive): Check for duplicate
4480 USE_SEIZE_FILE directives using same_file.
4481 * decl.c (pop_module): Remove dubious call to chill_same_grant_file.

4488 Use chill_result_decl appropriately.
4489 * ch-tree.h, decl.c, actions.c (saved_result_rtx): Removed.

4497 * actions.c (chill_expand_assignment): Check for compatibility
4498 _after_ "expanding out" a binary operation. This fixes
4499 the case "STRING //:= CHAR".
4501 * lex.l (equal_number): Convert symbol to integer_type_node, to
4502 force the value to be INT-derived (and avoid novelty conflicts).
4504 Mon Apr 4 22:06:31 1994 Per Bothner (bothner@cygnus.com)
4506 * ch-tree.h (CH_FUNCTION_SETS_RESULT): New flag.

4555 a process argument has other attribute then IN or LOC.
4556 * tasking.c (build_start_process): Add check that the optset is
4557 referable in case it is specified (this makes
4558 noncompile/start_.ch working).

4606 * typeck.c (build_chill_modify_expr): Simplify.
4608 Sun Mar 27 19:30:25 1994 Bill Cox (bill@rtl.cygnus.com)

4715 * expr.c (chill_expand_expr): Code to expand SET_IN_EXPR,

4750 to be compatible with the N-value class, with suitable M and N.
4751 * typeck.c (build_chill_slice): Don't smash a void TREE_TYPE.

4754 * expr.c (build_compare_expr): Fix thinko. Add save_exprs.
4756 * expr.c (build_compare_expr): Fix a transcription bug
4757 (for converting NULL INSTANCEs). Also #include convert.h.

4788 to have consistent operand types.
4789 * typeck.c (valid_array_index_p): Change interface to pass
4790 validity conditions back on caller's TREE_LIST. We
4791 cannot link the conditions to anything which a
4792 layout_type routine will expand, since that will occur
4793 before the exception handler is set up.
4794 Change calls to valid_array_index_p also.

4809 * typeck.c, ch-tree.h (build_chill_slice): Make non-static.
4810 * expr.c (varying_to_slice): Call build_chill_slice (and not
4811 build_chill_slice_with_length, which does bunches of range
4812 checking and does not allow the length to be zero).
4813 * convert.c (convert): Fix off-by-one error.
4814 * actions.c (chill_expand_array_assignment): Minor cleaning up.

4819 take *two* pointer parameters, not one.
4820 * satisfy.c (satisfy): Only call the appropriate layout routine
4821 if TYPE_SIZE is 0 (i.e. type hasn't already been laid out).
4822 * typeck.c (build_chill_slice_with_length): Fix Bill's previous fix.

4834 [case CONCAT_EXPR]): Remove kludge setting slice size upper bound
4835 in TYPE_LANG_SPECIFIC, and restore kludge setting it in MAX_VALUE.
4836 * typeck.c (build_chill_slice): Use TYPE_MAX_VALUE of
4837 array_type if needed for size upper bound of slice_type.
4838 * expr.c (build_concat_expr): Improve calculation of size upper bound.
4840 * typeck.c (valid_array_index_p): Check compatibility using
4842 * typeck.c (build_chill_slice_with_length); For now revert
4843 calling valid_array_index_p on length. (It makes it harder
4844 to realize when the slice is constant length.)
4845 * expr.c (build_chill_indirect_expr): Minor tweak. (This
4846 seems to work around a weird C compiler bug. ??)
4848 * expr.c (build_chill_function_call): Cleanup so it doesn't
4849 call build_function_call (in c-typeck.c).
4850 * typeck.c, expr.c: Use build_chill_function_call instead of
4851 build_function_call (in c-typeck.c).
4853 * parse.y (discrete_mode): Move some of the rules from
4854 non_array_mode into new non-terminal.
4855 (arrayindex): Use discrete_mode (with NAME and TYPENAME) to
4856 avoid some misparses.
4857 * ch-tree.h (SLICE_PTR, SLICE_LENGTH): Removed; unused.
4858 * convert.c (digest_structure_tuple): Add missing parameter.
4859 * decl.c (comptypes): Remove unused prototype.
4860 * decl.c (build_chill_function_type): Handle NULL return_type
4861 correctly (convert to void_type_node).
4862 * decl.c (init_decl_processing): layout boolean_type_node *after*
4863 we've set it's TYPE_MIN_VALUE and TYPE_MAX_VALUE.
4865 Wed Mar 16 16:08:22 1994 Bill Cox (bill@rtl.cygnus.com)
4867 * ch-tree.h: Add prototype.
4868 * convert.c (convert): Correct calculation of padding length.
4869 * decl.c (grok_chill_fixedfields): Move ignore_exprs test to
4870 parse.y where it belongs. This permits the removal of a kludge
4871 in make_process_struct.
4872 * lex.l, parse.y: Call to_global_level for several errors. Add
4873 code to output error in only one pass.
4874 * tasking.c (make_process_struct): Delete kludge inserted on
4876 (build_receive_case_end): Add Wilfried's check for errors.

4880 * actions.c: Fix comment.
4881 (build_rts_call): Ifdef it out - never used.
4882 (expand_varying_length_assignment): call valid_array_index_p.
4883 rather than validate_varying_array_ref.
4884 * ch-tree.h: Fix prototype for valid_array_index_p.
4885 * expr.c (chill_expand_expr): Call build_chill_array_ref to get
4887 (build_hill_lower, build_chill_upper): Return value now inherits
4888 the novelty of the input parameter.
4889 (varying_to_slice): Use CH_NOVELTY macro rather than calling
4890 chill_novelty directly.
4891 * grant.c (newstring): Make len unsigned and cast xmalloc parameter
4893 (print_integer_type): Pass string value as APPEND's second parameter.
4894 (decode_decl): Pass a boolean expression as print_proc_tail's
4896 (chill_finish_module_code): Make xmalloc's parameter unsigned.
4897 * lex.l: Pass sizes to xmalloc as unsigned ints. Pass second
4898 parameter to in_word_set as unsigned.
4899 * loop.c (build_loop_start): Check top_loop_end_check return value.
4900 * parse.y: Add casts to int for third do_decls parameter, fifth
4901 build_loop_iterator parameter, etc.
4902 * tasking.c (build_receive_case_end): Chack cond_stack before popping.
4903 * typeck.c (validate_varying_array_ref, chill_max_vary_array_index,
4904 valid_array_index): Delete them. They're now unused.
4905 (valid_array_index_p): Add function, call it everywhere that an
4906 array index is checked.
4907 (build_chill_slice): Restore old functionality where varying_to_slice
4908 is called to handle slices of varying arrays, rather than handling
4910 (build_chill_slice_with_range, build_chill_slice_with_length):
4911 Check range limits for TREE_CONST before calling tree_int_cst_lt.
4912 Delete now-obsolete checks of constant indices.
4914 Mon Mar 14 17:26:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4916 * parse.y (modeless_expr): New rule to allow ([...]) and (if...)
4917 to count as untyped_exprs. (This is not really permitted by the
4918 Blue Book, but has been requested by customers.)
4920 Thu Mar 10 10:11:02 1994 Bill Cox (bill@rtl.cygnus.com)
4922 * chill.texi: Document new command-line options.
4923 * expr.c (build_chill_num): Set unsigned parameter for
4924 type_for_size call correctly (unsigned for enums).
4925 * lang.c (lang_decode_option): Add command-line options to
4926 enable/disable runtime range-checking.
4927 * lex.l: Eat more whitespace.
4929 Thu Mar 10 09:41:37 1994 Bill Cox (bill@rtl.cygnus.com)
4931 * Makefile.in: Have rules to make parse.h, y.tab.c and other
4932 derived files. This allows the gcc/configure list of CHILL
4933 files machinery to work.
4934 * ch-tree.h (permanent_allocation): Add a parameter flag.
4935 * decl.c (finish_chill_function, finish_decl): Provide the
4936 new permanent_allocation flag.
4937 (poplevel): Return early, avoid a seg fault.
4938 * lex.l (NORMAL): Replace this whole state with the predefined
4939 INITIAL state. Force compilation state to global level after
4940 compiler directive error - prevents endless loop on error.
4941 (handle_use_seizefile_directive): Rewrite for readability.
4942 (chill_same_grant_file): Reindent.
4943 Generally handle whitespace differently.
4944 * regression.prpt: Print ten PR numbers per line. The report's
4947 Wed Mar 9 09:58:51 1994 Bill Cox (bill@rtl.cygnus.com)
4949 * decl.c (do_decl): Suppress the string-assignment-condition
4950 error - it was too often seen.
4951 * expr.c (expand_chill_expr): In CONCAT_EXPR, when argument has a
4952 runtime-changing length (as in a slice), get the parent array's
4953 allocation size from its type tree.
4954 * typeck.c (build_chill_slice): Support VARYING arrays. Pass
4955 parent array's static allocation size along in the slice type.
4957 Wed Mar 9 08:54:24 1994 Bill Cox (bill@rtl.cygnus.com)
4959 * lex.l (name_type_signal): Avoid dereferencing a NULL TRE_TYPE.
4961 Tue Mar 8 11:51:10 1994 Bill Cox (bill@rtl.cygnus.com)
4963 * expr.c (build_chill_sizeof): Fix typo in error msg, add
4965 * lex.l (name_type_signal): Add debug output.
4966 * parse.y (call): Allow EVENTNAME and BUFFERNAME parameters
4967 to a call, so that SIZE () works on them.
4968 * tasking.c (make_process_struct): Force ignore_exprs non-zero
4969 when processing a SEIZEd PROCESS declaration. This prevents
4970 grox-fixed_fields from returning a NULL, and indirectly protects
4971 the chill_integer_type_node tree from corruption.
4973 Mon Mar 7 19:14:05 1994 Bill Cox (bill@rtl.cygnus.com)
4975 * Makefile.in: Use the 'all' target to build the runtime
4976 library and chillrt0.o.
4977 * README: Explain rules for files in this directory.

4979 chill.regress.cron: Move to utils subdirectory.
4980 * expr.c (build_chill_function_call): Mark the INOUT
4981 temporary so it doesn't get optimized into a
4982 register. Fixes the execute/inout.ch bug.
4983 * typeck.c (layout_chill_range_type): Restrict it
4984 from complaining about an empty string type's
4987 Mon Mar 7 09:06:39 1994 Bill Cox (bill@rtl.cygnus.com)

5020 * lex.l (INITIAL): Remove all code to discard 'header lines'.
5022 * parse.y (optheader): Remove - it's obsolete, as is the
5023 HEADEREL token definition.
5025 Fri Mar 4 09:41:18 1994 Bill Cox (bill@rtl.cygnus.com)
5027 * addtest: Fix suffix removal when suffix is .c186.

5047 range-checking code. Handle reference_type in convert call.
5048 (chill_expand_assignment): Produce an INDIRECT_REF for a

5122 name for correctness.
5124 Wed Feb 23 15:07:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
5126 New cleaner solution to the following problem:
5127 Chill allows an action to be followed by an ON-handler.
5128 But we don't know if an action has a handler until we've parsed
5129 its end, yet we want to generate extra code to set up an
5130 exception handling contour only if needed. The old solution
5131 would generate code for the action into an rtl sequence, and then
5132 splice in the exception-setup code if we later found we needed it.
5133 This has a few problems (for example it confuses the management
5134 of stack temporaries), and is ugly. Now that the compiler is 2-pass
5135 we have a cleaner solution: In pass 1, we remember which actions
5136 were followed by ON-handlers. In pass 2, we use this information
5137 to generate appropriate code before an action.
5138 * except.c (push_handler, pop_handler): In pass 1, set up data
5139 structures (global_handler_list) to remember if an action has an
5140 ON-handler. In pass 2, digest this information, and setup
5142 * except.c, actions.h (pop_handler): Take an extra int arg.
5143 * except.c (emit_setup_handler): New function, with code (moved
5144 from chill_start_on) to emit code before an action that has a handler.
5145 * except.c (except_init_pass_2): New function.
5146 * parse.y (pass1_2): Call except_init_pass_2 before pass 2.
5147 * parse.y (POP_UNUSED_ON_CONTEXT): Don't call pop_sequence.
5148 * parse.y: Invoke POP_UNUSED_ON_CONTEXT and POP_USED_ON_CONTEXT
5149 in pass 1 as well as pass 2.
5150 * parse.y (BEGIN ... END): Re-arrange logic to avoid block_stack
5151 (local to ../stmt.c) getting out of sync.
5152 * actions.c (push_action): Don't need to emit a NOP,
5153 now that we're no longer moving sequences around.
5154 * actions.c (push_action): Call push_handler even in pass one.
5156 Wed Feb 23 11:06:14 1994 Bill Cox (bill@rtl.cygnus.com)

5219 mis-match if the LHS is varying.
5221 Fri Feb 18 18:10:04 1994 Bill Cox (bill@rtl.cygnus.com)

5253 * typeck.c (make_chill_array_type): Remove unused args.
5254 Simplify to build only one-dimensionsal arrays, so change
5255 index list to single index. Call layout_chill_array_type
5256 if pass!=1. And rename to: build_simple_array_type.
5257 * typeck.c (layout_chill_array_type): Only recurse
5258 if TREE_TYPE has not been laid out.
5259 * typeck.c (build_chill_array_type): Update accordingly.
5260 * typeck.c (build_chill_slice): Replace calls to build_array_type

5262 the TYPE_STRING_FLAG) by calls to build_simple_array_type.
5263 * convert.c (convert): The same.
5265 * grant.c (decode_constant): Clean up. Remove remnants of switch

5809 (chill_finish_compile): Delete unused code.
5810 * ch-lex.l: Make most build_init_2 calls from the
5811 permanent obstack, so that enumeration values endure.

5817 * ch-expr.c, ch-typeck.c: Rewrite some instances of
5818 'struct ch_class class = chill_expr_class (expr);' to
5819 'struct ch_class class; class = chill_expr_class (expr);'
5820 to work around a bug in /usr/ucb/cc on SunOS4.
5822 Mon Jan 10 18:29:36 1994 Bill Cox (bill@rtl.cygnus.com)
5824 * ch-actions.c (chill_convert_for_assignment): Avoid seg fault.
5825 * ch-expr.c (expand_packed_set): Add new parameter to pass

5828 expand_packed_set call.
5829 * ch-grant.c: Move extern declaration to ch-tree.h.
5830 * ch-lex.l (convert_bitstring): Also output the bitstring

5845 Also, fix some bugs for bitstrings (with ranges).
5847 (Patches from Tiemann.)
5848 * ch-convert.c (convert1): New function to force TREE_TYPE.
5849 (convert): Use convert1 where appropriate.
5850 * ch-typeck.c: Formatting change.
5851 * ch-parse.y (build_chill_constructor): Fix thinko.
5853 * ch-expr.c (varying_to_slice): If array is not referable,
5854 call save_expr on it, rather than stabilize_reference.
5855 * ch-satisfy.c (safe_satify_decl, for CONST_DECL):
5856 Don't force value to value class if mode is not explicitly
5857 specified. Also, make sure convert etc is only done once.
5859 Sat Jan 8 16:37:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
5861 * ch-decl.c (build_chill_function_type): Don't call
5862 build_function_type, because it does hash canonicalization,
5863 which once in a while looses badly.
5864 * tree.c (build_function_type): Remove no-longer-needed test
5865 for doing_chill_thang.
5867 * ch-tree.h (CH_DERIVED_FLAG): New flag.

5881 convert_float, convert_number): Set CH_DERIVED_FLAG for literals.
5882 * ch-expr.c (finish_chill_binary_op): Use convert_to_class.
5883 * ch-satisfy.c (safe_satisfy_decl): For CONST_DECL, make sure
5884 DECL_INITIAL gets set to result of convert.
5885 Also, clear CH_DERIVED_FLAG for SYN value.
5886 * expr.c (store_constructor): If a [power]set is exactly one
5887 word long, use single-word move.
5889 Sat Jan 8 08:38:29 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5891 * c-typeck.c (chill_initializer_constant_valid_p): Fix typo.

5895 * ch-typeck.c (build_chill_slice_with_length): Test that ARRAY is of
5896 ARRAY_TYPE before assuming so. Also, subtract 1 from LENGTH in
5897 computation of SLICE_END.

5904 for unary set operations).
5906 * ch-expr.c (build_chill_array_expr): Take new argument FORCE. All
5907 callers changed. All callers changed.
5909 * ch-convert.c (digest_structure_tuple): Handle SELECTED_VARIANT
5910 being NULL_TREE until we've started walking the list of values via
5911 the loop over VARIANTs.
5913 * ch-parse.y (build_chill_constructor): If we see an IDENTIFIER_NODE,
5914 treat it as an enum value (and hence constant). Also, only set
5915 TREE_STATIC if the constructor is indeed constant.
5916 * c-typeck.c (chill_initializer_constant_valid_p): If we see a
5917 VAR_DECL, test the TREE_CONSTANT field of the DECL_INITIAL, don't
5918 recurse on the DECL_INITIAL.
5920 Wed Jan 5 01:24:50 1994 Bill Cox (bill@cygnus.com)
5922 * Makefile.in: Add CHILL to LANGUAGES variable.
5923 * ch-actions.c (check_range): Call build_binary_op instead of
5924 fold, build to get the common types chosen.
5925 (cond_range_exception, cond_overflow_exception,
5926 cond_type_range_exception): Delete, obsolete.
5927 (chill_convert_for_assignment): Enable this, get particular
5928 about when to generate rangecheck code.
5929 * ch-expr.c (build_chill_function_call): Sketch in where to
5930 perform chill_convert_for_assignment on actual parameters.
5931 (build_chill_addr_expr): Correct compiler warning.
5932 * ch-loop.c (build_chill_iterator): Add runtime check for
5933 negative loop step expression.
5934 * ch-tree.h: Add prototype.
5935 * ch-typeck.c (chill_max_vary_array_ref): Correct misunderstanding.
5936 A varying array's length field counts the NUMBER of active array
5937 array entries, not the byte-length of them.
5939 Tue Jan 4 17:57:39 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5941 * ch-decl.c (do_decl): Call `suspend_momenary' if the
5942 converted constructor must live on the permanent_obstack.
5943 * ch-convert.c (convert): When building a new SET_TYPE
5944 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5945 * c-typeck.c (chill_initializer_constant_valid_p): Handle VAR_DECLs.
5947 * ch-typeck.c (chill_location): CONSTRUCTORS that are static

5950 on permanent_obstack if necessary.
5952 * ch-convert.c (digest_structure_tuple): When building a new SET_TYPE

5956 the patch below helped to mess up.
5958 * ch-expr.c (build_chill_arrow_expr): Call `mark_addressable'.
5959 (build_chill_addr_expr): Take new argument ERRORMSG.
5960 All callers changed. Also, call `build_chill_addr_expr' where
5961 we used to call `build1 (ADDR_EXPR, ptr_type_node, ...)' since
5962 that now calls `mark_addressable' automagically.
5964 * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.
5965 This is needed because variables may appear in initialization
5966 statements, and their DECL_INITIALs are their values at
5967 initialization time.
5968 * ch-convert.c (digest_structure_tuple,digest_constructor): Changed
5969 to handle VAR_DECLs as initializers.
5971 * ch-convert.c (digest_structure_tuple): Copy elements of INITS so
5972 they aren't destroyed for later use.
5974 Tue Jan 4 15:25:30 1994 Bill Cox (bill@cygnus.com)
5976 * ch-expr.c (chill_expand_expr): Correct check-range lo_limit
5977 parameter for varying_array_ref calculations.
5978 (build_chill_indirect_ref): Prevent seg fault due to syntax error.
5979 * ch-typeck.c (build_chill_slice_with_range): Correct issuance
5980 of bogus error in votrics.
5981 (build_chill_slice_with_length): Change for debug tracability.
5983 Tue Jan 4 02:43:37 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5985 * ch-convert.c (digest_structure_tuple): Fix phasing problem in
5986 handling variant record initializers.
5987 (various places): Change `pop_init_level' calls to match
5988 `push_init_level' wrt implicit variable.
5990 * ch-typeck.c (build_chill_slice): Convert the dynamic max index to
5991 `integer_type_node' before using it in comparisons. FIXME: should
5992 this be done in `chill_max_vary_array_index' by default?
5994 Tue Jan 4 00:24:14 1994 Bill Cox (bill@cygnus.com)
5996 * ch-actions.c: Fix comments.
5997 * ch-parse.y: Define caseaction_flag.
5998 (caseaction): Create new caseaction_flag node at the start,
5999 then free it at the end. Check it before the ELSE code.
6000 (expanded_case_label): Check the flag here. If set in either
6001 place, generate a jump to the end of the case.
6002 * ch-typeck.c (build_chill_slice_with_length,
6003 build_chill_slice_with_range): Add lots of compile-time
6004 parameter range checking.
6006 Mon Jan 3 21:49:04 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6008 * ch-convert.c (digest_structure_tuple): Call `push_init_level' with
6009 implicit==0 everywhere, not 1.
6010 (digest_constructor): Ditto.
6012 * ch-actions.c (check_range): Permit limits to be NULL_TREE.
6013 Also, hack out some dead code.
6014 * ch-typeck.c (build_chill_slice): Check varying and non-varying
6015 slice constructs for range failures.
6016 (build_chill_slice_with_range): Reindented, but not changed.
6018 * ch-typeck.c (chill_max_vary_array_index): New function.
6019 * ch-expr.c (chill_expand_expr): Call it.
6021 * ch-decl.c (var_data_id, var_length_id): New variables.
6022 (init_decl_processing): Initialize them. All calls to
6023 get_identifier (VAR_LENGTH or VAR_DATA) are now replaced
6024 by references to these variables. This simplifies the code
6025 w/o obscuring anything.
6027 Mon Jan 3 21:24:44 1994 Bill Cox (bill@cygnus.com)
6029 * c-typeck.c: Fix comment.
6030 * ch-actions.c (chill_expand_assignment): Error assigning to
6031 READONLY location. (PR_3903) Pass filename, linenumber
6032 to setbitpowerset runtime routine.
6033 * ch-decl.c (init_decl_processing): Add filename, linenumber
6034 parameters to setbitpowerset prototype.
6035 * ch-expr.c (build_chill_function_call): Error when passing a
6036 READonly location as a LOC or INOUT parameter.
6037 * ch-parse.y (mode): Correct code marking type as readonly.
6039 Mon Jan 3 19:03:55 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6041 * ch-actions.c (chill_expand_assignment): Disable code that defeats
6042 building varying array references.
6043 * ch-expr.c (chill_expand_expr): Add rangecheck code to
6044 VARY_ARRAY_REF case.
6045 * ch-typeck.c (build_chill_array_ref): Don't call an `expand_'
6046 function (in this case, `validate_varying_array_ref') when we're
6047 doing a `build_' operation.
6049 * ch-typeck.c (validate_varying_array_ref): Simplify interface
6050 since INDEX parameter can never meaningfully be an INDEXLIST.
6051 * ch-actions.c (expand_varying_length_assignment): Caller changed.
6053 Mon Jan 3 07:29:45 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6055 * ch-typeck.c (build_chill_cast): Set TREE_CONSTANT on NOP_EXPRs.
6056 * ch-convert.c (digest_structure_tuple): Switch to permanent_obstack
6057 if we need to build a CONSTRUCTOR for a SET_TYPE initializer.
6058 (digest_structure_tuple): If TREE_VALUE (VALUE) == NULL_TREE, don't
6059 call CH_COMPATIBLE or try to convert it to TREE_TYPE (FIELD). This
6060 can happen when constructors are output incrementally.
6061 * c-typeck.c (initializer_constant_valid_p): Handle SET_TYPEs.
6062 * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
6065 Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6067 * ch-convert (digest_structure_tuple): Handle SET_TYPEs. Also, call
6068 `convert' so we can handle INSTANCE types (and other anomolies)
6071 * ch-convert.c (digest_structure_tuple): Fixed variant
6072 structure initialization. Also fixed a typo (TYPE_NAME
6073 was being used on a FIELD_DECL instead of DECL_NAME).
6074 * c-typeck.c (initializer_constant_valid_p): Pass missing
6075 ENDTYPE argument on recursive call.
6076 (set_init_field): New function, needed by ch-convert.c change above.
6078 * ch-decl.c (layout_chill_variants): Added a FIXME next to an
6079 almost certain typo.
6081 * ch-expr.c (build_chill_arrow_expr): Call `build1' and set
6082 TREE_CONSTANT for static references.
6083 * ch-except.c (chill_start_on): Change calls to
6084 `build_unary_op' (which is C-specific) to `build_chill_arrow_expr'
6085 which has CHILL semantics.
6086 * ch-convert.c (convert): Ditto (albeit in some disabled code).
6088 Sat Jan 1 21:26:43 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6090 * ch-satisfy.c (safe_satisfy_decl): Reorder conditional test of
6091 TREE_CODE of DECL in case it's altered by actions in the switch.
6093 * ch-satisfy.c (satisfy): Undo abort added earlier on 1 Jan. CVS log
6094 mentions where to find code that triggers this case.
6096 * ch-actions.c (adjust_parm_or_field): Handle CONSTRUCTORS here as
6099 * ch-convert.c (digest_structure_tuple): Push to permanent_obstack if
6100 we're dealing with a CONSTRUCTOR that is TREE_PERMANENT.
6101 (digest_constructor): Ditto.
6103 Sat Jan 1 10:29:19 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6105 * ch-parse.y (handleraction,resultaction,assignaction,call): Modified
6106 so that CONSTRUCTORS are properly handled before being used.
6108 * ch-convert.c (chill_start_init): New function. All callers to
6109 `start_init' changed to call this function instead.
6110 (digest_struct_tuple): Defend against initialization machinery
6111 mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
6112 IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
6113 needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
6114 can be refered to throughout the compilation unit. Also remove an
6115 extraneous call to `process_init_element' erroneously added to the
6116 variant record sub-loop.
6117 (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
6118 CONSTRUCTORS of SET_TYPE.
6119 * ch-parse.y (build_chill_constructor): Refix typo. Also set
6120 TREE_STATIC if at top level.
6122 * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
6123 TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
6124 should have been called.
6126 * ch-convert.c (digest_struct_tuple): Restore code which tracks
6127 field initializations so that the compiler can deduce what variant
6128 initializations to assume.
6130 * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
6131 when we push into a scope that has a DECL with a CONSTRUCTOR as its
6134 * ch-parse.y (build_chill_constructor): Change the name of the
6135 parameter to something more meaningful. Fix typo. Also, handle case
6136 where element is an untyped CONSTRUCTOR.
6138 * ch-except.c (finish_handler_array): Set TREE_CONSTANT on
6139 constant ADDR_EXPRs.
6140 (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT
6141 on JBUF_REF (instead of calling `build1' which does not).
6143 * ch-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
6145 * ch-typeck.c (chill_expand_tuple): Deleted.
6146 * ch-parse.y (primval rule): Don't call `chill_expand_tuple';
6147 instead, use initialization machinery for CONSTRUCTORS that
6149 * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
6150 that are created here.
6151 * ch-satisfy (satisfy): Abort in case we would have called
6152 chill_expand_tuple. FIXME: some other code is needed here,
6153 but I don't know what yet.
6155 * ch-parse.y (build_chill_constructor): New function to
6156 propagate TREE_CONSTANT bits to CONSTRUCTORS.
6157 (untyped_expr rule): Use it.
6158 (primval rule): Use it.
6160 * ch-decl.c (do_decl): Call `finish_init'.
6161 * ch-convert.c (convert): If we spontaneously create a CONSTRUCTOR in
6162 this function, make sure the initialization machinery is set up.
6164 * ch-convert.c (digest_structure_tuple, digest_constructor): Add
6167 Fri Dec 31 11:31:01 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6169 * ch-grant.c (chill_finish_module_code): Mark ADDR_EXPR built by hand
6170 as being TREE_CONSTANT. Otherwise it gets bounded by the initializer
6173 * ch-decl.c (do_decl): Change in CONSTRUCTOR handling due to...
6174 * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
6175 rewritten to work with GCC's initialization code. The basic change
6176 was to keep the initializers in sync with the initialization
6177 machinery that `process_init_element' imposes. Both of these
6178 functions now return `void'.
6179 * ch-convert.c (convert): Changed calls to `digest_...' functions.
6181 FIXME: the code handling UNION_TYPE (and variant records) has not
6184 Fri Dec 31 15:32:56 1993 Bill Cox (bill@rtl.cygnus.com)
6186 * ch-lex.l (convert_number): Output the converted number if

6191 Fri Dec 31 13:17:48 1993 Bill Cox (bill@cygnus.com)
6193 * ch-parse.y: Cleanup handling of RETURN actions, to distinguish
6194 a RETURN without a value (which cannot have an exception
6195 handler) from a RETURN with a value (which can). Eliminate
6196 some shift/reduce and reduce/reduce conflicts.
6198 Thu Dec 30 17:42:32 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6200 * ch-inout.c (build_chill_writetext): Deal with 2 cases where
6201 types returned from `type_for_size' are not expected. FIXME.
6202 * ch-decl.c (init_decl_processing): Mark `char_type_node' unsigned.
6203 This is required when range checking is enabled.
6205 Thu Dec 30 14:28:25 1993 Bill Cox (bill@rtl.cygnus.com)
6207 DELAY CASE works now.
6208 * ch-decl.c (init_decl_processing): Move rest of tasking-related

6228 failed full regression testing.
6229 * ch-lex.l (name_type_signal): Add debug output.
6230 * ch-parse.y (structured_variable): Add a debug variable.
6232 Wed Dec 29 02:05:51 1993 Bill Cox (bill@rtl.cygnus.com)
6234 * ch-decl.c (get_next_decl): Revert change which failed full

6239 DELAY actions work now.
6240 * ch-decl.c: Correct spelling in comments.
6241 (get_next_decl): NULL out the decl's TREE_CHAIN before returning

6244 * ch-expr.c (build_chill_indirect_ref): Prevent a syntax error from
6245 becoming a seg fault.

6252 (locdec): process event decls here, too.
6253 (mode): Add code to forbid READonly EVENT and BUFFER decls. Delete
6254 code which required EVENTs and BUFFERs to be declared at global scope.
6255 (simple_name_string): Add an EVENTNAME.
6256 * ch-satisfy.c (safe_satisfy_decl): Prevent a syntax error from
6257 becoming a seg fault.

6260 (build_receive_case_start, build_receive_case_label): Defer
6261 calling runtime routine until we know whether we have a signal
6262 or a buffer to wait for.

6272 options. Delete C-specific defines. Disable piping from
6273 pre-processor to cc1chill (even if -pipe is specified), since cc1chill
6274 rewinds its input for its second pass. Piping still works
6275 from cc1chill to as.

6286 Wed Dec 22 10:46:31 1993 Bill Cox (bill@rtl.cygnus.com)
6288 * ch-decl.c (do_seize): Delete - it's unused. Fix comments.
6289 * ch-loop.c (build_chill_iterator): Convert BY expression

6315 distinguish a string from a char array, and to distinguish a
6316 bitstring from regulat (power)set. (Needed for Chill.)
6317 * dbxout.c (dbxout_type): Only check for baseclasses in
6318 type.binfo is a vector. (It is used in Chill for tagged unions.)

6340 * ch-tree.h: Fix prototypes.
6341 * ch-typeck.c (smash_dummy_type): Handle all four kinds of LANG_TYPE

6359 (non-seize) declarations are proclaim_decl'd *before* we
6360 handle the ALIAS_DECLs for seizes. The advantage is
6361 that we can now test for (an approximation) to the

6363 when a module has both GRANTs and SEIZE ALL.
6365 * ch-expr.c (build_chill_arrow_expr): No longer re-write
6366 addr-of-conversion to pointer-conversion-of-addr.
6367 * ch-expr.c (build_chill_addr_expr): Re-write to just use

6376 * ch-expr.c (finish_chill_binary_op): Use CH_ROOT_RESULTING_MODE
6377 macro (which works on expressions), rather than CH_RESULTING_MODE
6378 (which works on modes, and isn't quite correct).

6505 of set elements of similar set modes.
6507 * ch-parse.y (caseaction): Call language-independent

7115 specify a value for each of them.
7116 * ch-parse.y (check_end_label, action, exceptlist): Only output
7117 error message in pass 1.
7118 (sendaction): Add comments.

7126 parameter to know whether to include an init expression.

7394 * ch-typeck.c (chill_location): New function.
7395 Based on lvalue_p, but also handle Chill-specific VARY_ARRAY_REF.
7396 * ch-typeck.c, ch-tree.h (CH_LOCATION_P), ch-convert.c: Use
7397 chill_location instead of lvalue_p.
7400 Fri Oct 1 11:28:42 1993 Bill Cox (bill@cygnus.com)

7416 ch-convert.c (convert): Use it.
7417 * ch-typeck.c (build_chill_slice): Take length rather than upper
7418 bound. This makes it easier to recognize that A(X UP LENGTH)
7419 really has fixed length. Also, if the argument is string,
7420 mark the slice as a string too. Also, handle varying strings.
7422 * ch-typeck.c (conflate_singleton_strings): New global.
7423 * ch-typeck.c (chill_similar): If conflate_singleton_strings is
7424 set (as it currently is), allow CHARS(1)/BOOLS(1) to be similar

7426 * ch-convert.c (convert_to_char): Convert CHARS(1) to CHAR.
7427 * ch-convert.c ( build_array_type_for_scalar): If input is string,
7429 * ch-convert (maybe_turn_scalar_into_arra), ch-tree.h: Removed.
7430 * ch-convert.c (convert): Convert CHAR to CHARS(1).
7432 This fixes 'X // := Y' and is also a general simplification.
7433 * ch-actions.c (chill_expand_assignment): Convert 'LHS OP := RHS'
7434 to 'LHS := LHS OP RHS' (using stabilize_reference on LHS).
7435 Also, call save_expr on RHS if a multiple assignment.
7436 * ch-parse.y (assignaction): Therefore, no longer need to call
7437 stabilize_reference on RHS.
7438 * ch-typeck.c (build_chill_modify_expr), ch-tree.h: Remove
7439 modifycode parameter. Make it the caller's responsibility to

7442 ch-loop.c: Fix calls to build_chill_modify_expr accordingly.

7451 * ch-tree.c (build_string_type): Pass string_index_type_dummy as
7452 the parent type of the index range.
7453 * ch-typeck.c (layout_chill_range_type): Recognize and handle
7454 string_index_type_dummy - specifically allow an empty range.

7458 * ch-convert.c (convert_to_reference): Check for loc-identity
7459 mismatches correctly (and remove one of those chill_compatible
7461 * ch-decl.c (decl_tasking_code_var): New function, called from
7462 push_extern_process and push_extern_signal.
7463 * ch-parse.y (end_function): Delete parameter. Check current_function_decl
7464 whether it's actually a process, and whether it has parameters.
7465 Make Michael's change simplifying the pass 2 test, preventing a seg
7467 (procedure, process): Change calls to end_function, remove
7468 code saving value from build_process_header. Delete redundant chill_
7469 phrases from some function calls.
7470 * ch-tasking.c: Remove some redundant _chill phrases from function
7472 * ch-tree.h: Remove some redundant _chill phrases from function
7473 names. Add the CH_VARYING_ARRAY_TYPE macro, call it from
7474 all relevant places.
7475 * ch-typeck.c: Use the new macro. Cast TREE_CODEs to chill_tree_code.
7477 Wed Sep 29 13:07:43 1993 Per Bothner (bothner@kalessin.cygnus.com)

7481 with a recursive convert call.
7482 * ch-decl.c (do_decl): Add missing compatibility-checking
7483 of initializer (don't depend on convert).

7487 * ch-tree.h (CH_LOCATION_P): New macro.
7488 * ch-typeck.c (layout_chill_range_type): Fix call to
7489 type_for_size, when figuring out a defaulted parent type.
7490 * ch-expr.c (build_chill_lower, build_chill_sizeof): Check
7491 for TREE_CODE_CLASS != 't' rather than == 'd'.
7492 * ch-expr.c (build_chill_function_call): Use CH_LOCATION_P
7493 to check for location, rather than TYPE_CODE_CLASS == 'd'.
7495 * ch-tree.c (build_string_type): Make 2-pass safe. Also,
7496 change parameter to be length, not index type.
7497 * ch-parse.y (mode2), ch-expr.c (build_concat_expr), ch-lex.l

7501 * ch-grant.c (grant_array_type): Make more robust for char-
7502 and bit-strings (allow non-constant sizes). Change parameters
7503 and return types. (raw_decode_mode): Use grant_array_type
7504 for bitstrings. (otherwise): Fix grant_array_type callers.
7506 Mon Sep 27 16:57:57 1993 Per Bothner (bothner@kalessin.cygnus.com)
7508 Remove changes of Sep 15.

7510 * ch-typeck.c (chill_similar): Don't allow a singleton
7511 powerset to be similar to its domain.
7512 * ch-convert.c (convert_to_boolean): Don't convert a singleton
7513 SET_TYPE constructor to a Boolean.
7515 * ch-actions.c (chill_expand_assignment): Handle IN_EXPR on
7516 LHS of assignment, which is what we're current (temporarily?) using.
7518 Mon Sep 27 06:01:57 1993 Bill Cox (bill@rtl.cygnus.com)
7520 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
7521 ch-grant.c, ch-inout.c, ch-parse.y, ch-satisfy.c,
7522 ch-tasking.c, ch-tree.c, ch-tree.h, ch-typeck.c:
7523 -Wall cleanup. Add prototypes where missing.
7524 Delete unused variables. Cast uses of tree_codes
7525 to chill_tree_code, which they are.
7527 Sun Sep 26 13:09:57 1993 Bill Cox (bill@rtl.cygnus.com)
7529 * ch-decl.c (do_decl): Save initializer in pass zero
7531 * ch-lex.l: Fix comments, indentation.
7532 * ch-parse.y: Standardize error messages to use
7533 uppercase for CHILL keywords rather than quoting them.
7534 Suggestion from docs department.
7535 * ch-tasking.c: Pervasive changes to get processes to
7537 * ch-tree.h: Delete prototypes for functions whic
7538 I made static inside ch-tasking.c.
7540 Sun Sep 26 02:40:02 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7542 * ch-lex.l (yywrap): Call `check_newline' in case the file
7543 started with a line directive.

7547 * ch-decl.c: Expand pre-amble comment.
7548 * ch-decl.c (struct scope, push_module): Use new field
7549 tail_chain_module to build child-module list in order.
7550 (Just to make compiler debugging a little less confusing.)
7552 * ch-decl.c (struct scope): New field weak_decls.
7553 * ch-decl.c (find_implied_types): New interface. Now pre-pend
7554 new enum types to a given input list. This makes it easier to
7555 avoid duplicates, which should at least be more efficient.
7556 Also, handle FUNCTION_DECL.
7557 * ch-decl.c (bind_saved_names): Removed. Distribute its
7558 functionality over new functions (push_scope_decls, pop_scope_decls,
7559 build_implied_names, bind_sub_modules). The goal (which seems to
7560 have been more-or-less attained) was to fix weak name handling.
7561 * ch-decl.c (poplevel): Use new function pop_scope_decls.
7563 * ch-tasking.c (build_signal_struct, build_tasking_message_type):
7564 Use build_decl directly, rather than grok_chill_fixedfields
7565 (which depends on ignore_exprs and has more overhead).
7566 * ch-tasking.c (build_signal_struct): Construct the type
7568 * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
7569 than build_array_ref (which does C-specific "optimizations").
7570 (Hence move my_build_array_ref up earlier in the file.)
7572 Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7574 * ch-tasking.c: Declare static variable `void_ftype_void'.
7575 (chill_tasking_init): Initialize `void_ftype_void' here.
7576 (build_tasking_struct): Use, don't declare `void_ftype_void'.
7577 (generate_tasking_code_variable): Call `do_decl', not
7578 `decl_temp1' to declare TASKING_CODE_NAME.
7579 (tasking_setup): Drop into 1-pass mode so that all
7580 tasking-related declarations are installed in the global
7581 scope. Use correct CHILL types for initializers (since
7582 ptr_type_node doesn't have the right meaning for CHILL).
7583 Also, call `do_decl' instead of `decl_temp1' for
7585 (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
7586 `chill_finish_compile' in sync between passes.
7588 * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
7589 declarations on pass zero. Keep obstacks in sync, and always
7590 call `finish_decl' for pass zero declarations.
7591 (push_chill_extern_function): Keep obstacks in sync, and always
7592 call `finish_decl' for pass zero declarations.
7593 (build_enumerator): Ditto.
7594 (grok_chill_variantdefs): Change PASS test to exclude only
7596 (finish_struct): Ditto.

7605 extra pushing and popping of obstacks.
7607 * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
7608 on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
7610 * ch-grant.c (chill_finish_compile): Clear out both
7611 MODULE_INIT_LIST and TASKING_LIST if either contains stuff
7614 * ch-parse.y (rccase_label): Add NAME rules so that pass one
7615 works w/o knowing we're parsing a signal. Simplify SIGNALNAME
7616 rules since we only get SIGNALNAME tokens in pass two.
7617 (sendaction): Ditto.
7618 * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
7619 BUFFERNAME on pass two. The grammar now handles this.

7622 Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
7624 * ch-decl.c (lookup_remembered_names): Removed. It was being
7625 misused in ch-lex.l.
7626 * ch-lex.l (name_type_signal): Revert last change. Basically,
7627 we cannot use the C typedef/variable name trick in CHILL, due
7628 due to the language's 2-pass nature.
7629 * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
7631 * ch-tree.h (lookup_remembered_name): Comment out the prototype.
7633 Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)

7644 * ch-parse.y: Set pass to zero to indicate initial decl processing.
7645 Replace NAME references with SIGNALNAME references.
7646 (startaction): Only check copy number if not ignoring actions.
7647 Always call build_chill_start_process.
7648 (optstartset): Don't lookup the instance name.
7649 * ch-tasking.c (generate_tasking_code_variable): Replace
7650 do_decl call with decl_temp1 call.

7661 * ch-tasking.c (build_chill_receive_case_start): `namedecl'
7662 should be a _DECL, not an IDENTIFIER_NODE.

7685 ALIAS_DECL the name in the most recent use_seize_file directive.
7686 (This requires that use_seize_file directives written to the
7687 grant file be written before the SEIZEs that need it.)
7688 Allow clashing declarations granted into the global scope
7689 (produce a warning), but remember the seizefile case from
7690 (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
7691 The a SEIZE will select the granted decl that matches its
7692 DECL_SEIZEFILE (in other words: grants from the most recent
7693 use_seize_file will be preferred).
7694 * ch-tree.h (DECL_SEIZEFILE), ch-tree.def: New macro.
7695 * ch-tree.h (global_value, IDENTIFIER_GLOBAL_VALUE): Renamed

7702 Don't call grant_use_seizefile.
7703 * ch-lex.l (mark_use_seizefile_written): New function.
7704 * ch-grant.c (decode_decl): Write out use_seize_file directive,
7705 if needed, before writing a seize declarations.

7707 module specially, setting IDENTIFIER_OUTER_VALUE.
7708 * ch-decl.c (lookup_name_for_seizing): Check IDENTIFIER_OUTER_VALUE.

8021 ch-expr.c (finish_chill_binary_op): For now, prefer IN_EXPR
8022 over BIT_FIELD_REF because of various problems with BIT_FIELD_REF
8023 (incomplete support for variable fields, and possible bug in

10299 function, for external and seized function declarations.
10300 Make sure to use permanent obstack.
10301 * ch-parse.y (quasi_pdef, extprocedure): Use new function.
10303 * ch-grant.c (chill_finish_module_code): Since module
10304 function is no longer visible,, can't get it using
10305 lookup_name(). Use current_function_decl instead.
10307 * ch-decl.c (build_chill_function_type): Add void_type_node
10308 to end of parameter types list.
10310 * ch-grant.c (chill_start_module_code): Make sure module

10381 (start state 'ccitt'): Deleted, unused. Moved unused, but reserved,
10382 tokens to NORMAL state.
10383 (compiler_directive): Replaced by equal_number. Now the only
10384 recursive call to yylex happens in check_newline at the beginning
10387 Sat Apr 10 09:55:50 1993 Bill Cox (bill@rtl.cygnus.com)
10389 * ch-actions.c (build_chill_case_expr): Added from ch-parse.y.
10390 * ch-lex.l (ENTRY, PERVASIVE, ROW, STEP): Add token recognition to
10392 * ch-parse.y (case_expr): Move code into ch-actions.c. There will

10395 * ch-tree.h (build_chill_case_expr): Add prototype.
10396 * ch-typeck.c (build_chill_cast): Allow untyped_expr - just assign the

10399 Sat Apr 10 01:10:51 1993 Per Bothner (bothner@rtl.cygnus.com)
10401 * ch-parse,y (in_pseudo_module): New variable. Try if we're
10402 in a seizefile, but not in a module nested in the seizefile.
10403 Use for backwards compatibility with old grantfiles.

10415 * ch-lex.l: Re-write to use start states, to avoid calling
10416 yylex() recursively.
10417 * ch-lex.l (compiler_directive); This is now obsolste. FIXME.
10418 * ch-lex.l: Call push_module and pop_module when reading a
10419 seizefile. This creates a pseudo-module.
10420 * ch-parse.y: Clean up handling of empty declarations and
10421 action statements; semicolons are now optional a number of
10423 * ch-parse.y: Remove some bogus tests for "statement
10424 out of sequence" (they're both legal and work).
10425 * varasm.c (mak_function_rtl): Remove kludge that may
10426 not be necessary (and loses anyway).
10428 Fri Apr 9 09:37:38 1993 Bill Cox (bill@rtl.cygnus.com)
10430 * ch-expr.c (chill_expand_array_assignment): Remove false error about

10447 which is the list (in order) of decls in the module.
10448 Don't reverse the getdecls() list; that is handled by caller.

10466 assignment, clean up.
10467 * ch-typeck.c: Add prototype for require_complete_type.

10480 * ch-tree.h (massage_param_node): New prototype.
10481 * ch-decl.c (push_parms): Use new massage_param_node().

10506 Mon Apr 5 19:56:56 1993 Bill Cox (bill@rtl.cygnus.com)
10508 * ch-actions.c, ch-decl.c: Use tree_int_cst_equal and integer_zerop

10528 Fri Apr 2 21:55:14 1993 Per Bothner (bothner@rtl.cygnus.com)
10530 Major re-write of New module/seize/grant stuff.
10531 Now, a grantfile is a spec module and contains all the
10532 top-level declarations of the granting module, not just
10533 those that are granted. It also contains explicit grant
10534 statements naming those declared names that are granted.
10535 It also has seize statements and use_seize_file directives
10536 to correctly handle transitive dependencies.
10538 * ch-parse.y: Change to allow multiple modules per source file.
10539 Allow spec modules (including quasi definitions) as well as
10541 Allow spec modules inside normal modules; these behave as if
10542 they were outermost. This violates the Blue Book, but is
10543 needed by the new grantfile mechanism. (A grant file is a
10544 spec module that gets included by the use_seize_file directive.)
10545 * ch-parse.y (struct module *current_module, push_module,
10546 pop_module): Support module nesting (for spec modules only).
10548 * ch-tree.h (struct module): New.
10549 * ch-grant.c (granted_decls): New list of declarations
10550 that have been granted into the outermode pseudo-module.
10551 * ch-grant.c (decode_mode): If the decl has a name,
10552 always write the name, not just if the decl has already
10553 been written. Since we write out all decls, we can assume
10554 it will be written later, and depend on the forward
10555 declaration kludges to catch it.
10556 * ch-grant.c (decode_decl): Don't write out _EXTERN.
10557 Instead write out standard (Blue Book) quasi-definitions.
10558 * ch-grant.c (push_granted): New function.
10559 * ch-grant.c (seize_implied_names): New function. Re-write
10560 how set element names are seized when a set type is seized.
10561 * ch-grant.c (chill_seize): Work by seraching the
10562 granted_decls list and copying the declaration.
10563 * ch-grant.c (chill_grant): Write all declarations
10564 declared in this module. Write GRANT statements for
10565 those granted. seize statements for decls seized from
10566 other modules. Write extra syntax to make a complete
10568 * ch-grant.c (grant_use_seizefile): Copy use_seize_file
10569 directives into grant file.
10570 * ch-lex.l (setup_seizefile_read): Call grant_use_seizefile.
10572 * ch-lex.l (struct input_state, current_input_state,
10573 push_input_file, pop_input_file): New (type, variable,
10574 function*2). Used to save and restore state on an input file.
10575 * ch-lex.l: Clean up to handle nested input seizefiles
10576 (needed by new grant/seize mechanism.
10577 * ch-lex.l (skip_to_end_of_directive): New function.
10578 * ch-lex.l (compiler_directive: USE_SEIZE_FILE): Make sure
10579 we skip to the end of the directive *before* we switch
10581 * ch-lex.l (setup_seizefile_read): Prevent reading the
10582 same seizefile twice (otherwise likely with new grant/seize).
10583 * ch-lex.l: Recognize SPEC. Misc cleanups.
10585 * ch-parse.y: Fixed foreward references of types.
10586 Removed the unknown_type_node crock.
10587 * ch-decl.c: Remove all uses of unknown_type_node.
10588 Check for TYPE_SIZE zero instead.
10589 * ch-decl.c (fixup_unknown_type): Make sure new mode
10590 gets copied into old mode. Merge their variant chains.
10591 * c-decl.c (lookup_name_current_level): Make non-static.
10592 * ch-decl.c (lookup_name_current_level): No longer needed.

10595 name following the CALL keyword.
10596 * ch-tree.h (struct lang_identifier): Add implicit_decl,
10597 and make sure order of fields matches c-tree.h.
10599 * ch-actions.c (lang_init, build_allocate_memory_call,
10600 build_allocate_globals_memory_call): Fix names (add initial '_')
10601 and prototypes of _allocate_[global_]memory (2nd param is ref).
10602 Use build_chill_function_call, not build_function_call,
10603 so the reference parameter gets handled.
10604 * ch-actions.c. (lang_init): Make sure boolean_{true,false}_node
10605 have boolean_type_node as their types.
10606 * ch-actions.c (build_chill_lower, build_chill_upper): Fix to
10607 work for arrays with BOOLEAN_TYPE ranges (and simplify some).
10609 * ch-except.c: Make sure an end_label is generated,
10610 and jump to it if there is no exception.
10612 * ch-convert.c (convert_to_reference): Strip off NOP_EXPR casts.
10613 * expr.c (expand_expr): Handle NOP_EXPR as Chill-style casts.
10614 (Need cleaning up and FSF installation!)
10615 * ch-parse.y: If taking the address of a cast, move the
10616 ADDR_EXPR inside the NOP_EXPR.
10618 * ch-typeck.c (my_build_array_ref): Simplified, more suitable
10619 versions of build_array_ref from c-decl.c. (E.g. don't barf
10620 if index type is char or bool.)
10621 * ch-typeck.c (build_chill_array_ref): Use my_build_array-ref.
10623 * ch-typech.c (build_chill_bin_type): New function.
10624 Support BIN(N) range type specification.
10625 * ch-parse.y (mode2), ch-lex.l: Recognize BIN(N).
10627 * ch-tree.h (CH_SIMILAR): Redefine in terms of chill_similar.

10629 that range types are similar to their parent types.
10631 * ch-tree.h: Declare flag_local_loop_counter.
10632 * ch-loop.c: Whether the loop variable is local to the loop
10633 in now controlled by flag_local_loop_counter, instead of

10635 * ch-actions.c (lang_decode_option): Recognize flags
10636 "-f[no-]local-loop-counter".
10637 * toplev.c (lang_options): Add Chill flags -f[no-]local-loop-counter.
10639 * varasm.c (make_function_rtl): Due to problems with forward
10640 references, don't rename nested functions in Chill. (Kudge!)
10642 Sun Mar 28 10:12:45 1993 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10644 * ch-lex.l (push_back, readstring): Fix prototypes.

10655 * ch-parse.y (get_type_of): Add function to deal with possible fwd
10656 declared type name. Call it from lotsa places. Add lotsa checks

10666 as-yet-undeclared types. Check for IDENTIFIER_NODE, lookup its
10667 DECL if there, pass TREE_TYPE of decl to build_pointer_type.
10668 (variantfields, varianthack): Clean up.
10669 (variantfield): Check for IDENTIFIER_NODE, lookup its DECL if
10670 there, pass TREE_TYPE of decl to grok_fixedfields.

10705 array and its type get on the permanent obstack.
10706 * ch-grant.c (write_grant_file): Don't write the _INIT=name
10707 specifier: It isn't needed, and loses (because of funny
10708 characters in the chill_initializer_name).
10709 * ch-decl.c (push_synmode): Set TYPE_NAME(mode) = syndecl.
10710 * ch-lang.c (finish_chill_enum): Don't allocate a dummy
10711 TYPE_DECL for the enum. I don't think it is needed (?),
10712 and removing it is needed for the change above.
10714 * ch-grant.c (grant_array_type, decode_mode): Remove unused
10716 * ch-grant.ch (raw_decode_mode): New function, based on old
10718 * ch-grant.c (decode_mode); This is now just a wrapper around

10722 Fri Mar 19 11:55:35 1993 Bill Cox (bill@rtl.cygnus.com)
10724 * ch-actions.c: Add prototypes, remove unused variables. Attempt to
10725 continue generating grant file in presence of error (Wilfried's
10726 patch to lang_finish).

10728 after each statement. Move convert call into
10729 chill_expand_assignment from ch-parse.y.
10730 * ch-grant.c: Generally re-order, clean up. Include Per's decode_mode
10731 simplification. Include commented-out hack in decode_mode to return
10732 type's name if type SEIZEd or already GRANTed in this file.
10733 * ch-lex.l: Add prototypes.
10734 * ch-parse.y (assignaction): Move convert call into

10748 * ch-parse.y (structured_variable): Return NULL_TREE is invalid WITH
10749 parameter is seen, don't count it in structured_variable_list. Pre-
10750 vents seg fault when only WITH operand is invalid.
10751 * ch-parse.y (label_spec): Correct assignment within IF expression which
10752 was intended to be equality test. Remove unused variables.
10753 * ch-tree.h: Add prototype. Remove unused EXCP_CODE enumeration, and
10754 prototyping editorial comments.
10755 * ch-typeck.c: Disable generation of code to validate array index for
10756 now. Should be done as a call-back from more generic array_ref code.
10757 Clean up parameter checking. Remove unused variables.

10794 * varasm.c (output_constant): Prevent seg fault - terminate case
10795 alternative with a 'break'.
10797 Mon Mar 8 17:13:00 1993 Bill Cox (bill@rtl.cygnus.com)
10799 * ch-expr.c (): Move SET_TYPE constructor to expr.c.

10879 * expr.c (expand_expr): Use actual library name for __inpowerset
10881 * stor-layout.c (variable_size): Disable complaint about variable-

10890 actual library names. Change references to boolean_type_node
10891 to references to the TREE_CODE == BOOLEAN_TYPE, to follow the

10896 need bitcount instead.

10898 version that does stuff we don't want.
10899 build_binary_op: Check for in_size_in_bytes return < 0, indicating

10905 build_chill_length: Move VARYING array handling before regular char
10907 * ch-expr.c chill_expand_expr: Disable concatenate code - we need to
10908 the VARYING status of the target to do this correctly. Use powersetlen
10909 for the powerset operations, not a byte length.
10910 * ch-loop.c: Make CREATE_SCOPE #define to enable creation of a new scope
10911 for each CHILL loop, as Z.200 requires. Add powerset and error flags
10912 to loop structure. Evaluate user's powerset expression into a temp,
10913 scan it destructively with __ffsetclrpowerset or __flsetclrpowerset
10914 for powerset loop. Only do loop-end assignments if NOT a powerset
10915 loop, which has much less overhead now.

10961 comes out error_mark_node, set ERRONEOUS.
10963 * ch-actions.c (build_chill_binary_op_1): If EXP is NULL_TREE,
10966 * ch-action.c (chill_comptypes): Test for structural
10967 equivalence of enums.

11191 New types chill_integer_type_node and chill_unsigned_type_node
11192 that correspond to the Chill source types INT and UINT.
11193 For now, these match the C 'short' types, but that should
11194 become a configuration option later,

11216 * ch-tree.def: add a new tree type - just for varying array
11217 references. We were using ARRAY_REF, but the underlying C
11218 code also generates that one.
11219 * ch-convert.c, ch-expr.c, ch-typeck.c: use the new tree type.
11221 Sun Feb 7 17:33:17 1993 Bill Cox (bill@rtl.cygnus.com)

11449 chill front end to distinquish between true string types and
11450 arrays of char, since it uses ARRAY_TYPE for both, rather than
11451 trying to use the existing support for STRING_TYPE.

11582 * modules: use gdb rather than naked-gdb, to get opcodes
11583 in chill definition.
11585 Wed Jan 6 09:48:35 1993 Bill Cox (bill@cygnus.com)
11587 * ch-typeck.c: add code to handle references to elements of VARYING
11588 arrays. Simplify chill_give_type_to_expr. Add rough draft of run-
11589 time index checking for VARYING arrays (under #if 0).
11590 * ch-actions.c: new function cond_type_range_exception & calls.
11591 New function cond_range_exception, for more general range-checking.
11592 New function build_varying_struct, to do just that. Use the macros
11593 for the special varying field names.
11594 * ch-tree.h: define macros for varying field names.
11595 * ch-expr.c: use macros for varying struct names. Simplify
11596 chill_expand_array_assignment.
11597 * ch-parse.y: assure that build_varying_struct is called everywhere
11598 that it applies. Add a line-number note before the body of a DO
11600 * ch-loop.c: #ifdef out creation of new scope for DO loop body.
11602 Tue Jan 5 17:26:14 1993 Bill Cox (bill@cygnus.com)

11607 Tue Jan 5 15:59:36 1993 Per Bothner (bothner@cygnus.com)
11609 * ch-grant.c (still_start_module_code), ch-parse.y (procedure):
11610 Move shared code into ...
11611 * ch-decl.c (start_chill_function): ... here.
11612 * ch-decl.c (start_chill_function): Add missing call to
11613 expand_start_bindings.
11614 * ch-decl.c (finish_chill_function): Add missing call to
11615 expand_end_bindings.
11617 Tue Jan 5 01:00:47 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

11623 * ch-expr.c: make chill_expand_array_assignment not static.
11625 Mon Jan 4 17:57:48 1993 Per Bothner (bothner@cygnus.com)
11627 * ch-grant.c, ch-parse.y: Remove all code for explicitly
11628 calling initializer functions. This is not needed, since we
11629 use the same mechanism used for C++ static constructors.
11630 * ch-grant.c (chill_start_module_code): Make sure the
11631 init_name starts with the magic string also used for C++
11632 initializers. Also, don't embed the file name in the name,
11633 just use the module name.
11634 * ch-grant.c (chill_finish_module_code): Now that the
11635 initializer name follows the standard 'collect' convention,
11636 don't need to call assembler_constructor_alias, but can
11637 use the standard assemble_constructor instead.
11638 * varasm.c (assemble_constructor_alias): Remove no-longer-
11640 * ch-parse.y: Move code that is common to the beginning of
11641 all functions to a new macro INIT_ACTION.
11642 Make sure INIT_ACTION is also done for callaction, fixing a bug.
11643 * ch-parse.y (INIT_ACTION): Do chill_start_module_code()
11644 before emit_line_note(), not after.
11646 Mon Jan 4 11:43:12 1993 Bill Cox (bill@cygnus.com)
11648 * ch-parse.y: restore requirement for :upper-bound in array decl.
11649 * ch-actions.c: enhance upper, lower, length functions for VARYING.
11651 Mon Jan 4 09:28:44 1993 Bill Cox (bill@cygnus.com)
11653 * ch-actions.c: fix NOT of boolean expr.
11655 Mon Jan 4 08:42:57 1993 Bill Cox (bill@cygnus.com)
11657 * ch-actions.c: provide range-checking function
11658 * ch-lex.l: better compiler-directive error messages,
11659 allow underscores in exponents
11660 * ch-loop.c: prevent passing NULL ptr to printf
11662 Sun Jan 3 11:57:13 1993 Bill Cox (bill@cygnus.com)
11664 * ch-typeck.c: correct & enable array index range-checking
11666 Sun Jan 3 11:36:39 1993 Bill Cox (bill@cygnus.com)
11668 * ch-parse.y: define IGNORED_DIRECTIVE
11669 * ch-typeck.c: subtract array's lower domain value, even if
11670 index expression is constant.
11672 Sat Jan 2 23:05:14 1993 Fred Fish (fnf@cygnus.com)
11674 * ch-lex.l (convert_float): Fix misspelling in error message.
11676 Sat Jan 2 16:02:16 1993 Per Bothner (bothner@rtl.cygnus.com)
11678 * Makefile.in: Took out chill-runtime support.
11679 Chill run times are now in ../chillrt, not ./chillrt.p
11681 Sat Jan 2 15:04:13 1993 Bill Cox (bill@cygnus.com)
11683 * ch-hash.h, chill.gperf: cleanup. fewer keywords seen by ch-parse.y.
11685 Sat Jan 2 13:27:49 1993 Per Bothner (bothner@rtl.cygnus.com)
11687 * ch-lex.l (check_newline): Use the orginal versions (derived
11688 from the C code, not the simplified, special-case version).
11689 Also, fix that version of check_newline to not call yylex()
11691 * ch-lex.l (yy_input): Call check_newline to handle
11692 newlines and check for # directives.
11693 * ch-lex.l (syntax): Don't recognize #-directives; these
11694 are now handled by check_newline.
11695 * ch-actions.c (lang_init): Call the modified version of
11696 check_newline(). Do this at the *after* we've initialized
11697 standard types, so this can be done while lineno is still 0.
11699 Sat Jan 2 10:57:20 1993 Bill Cox (bill@cygnus.com)
11701 * ch-hash.h, chill.gperf: add remaining reserved words.
11703 Sat Jan 2 09:59:55 1993 Bill Cox (bill@cygnus.com)
11705 * ch-tree.h, ch-parse.y, ch-lex.l: add remaining reserved words,
11706 names for exceptions
11708 Fri Jan 1 12:30:31 1993 Fred Fish (fnf@cygnus.com)
11710 * ch-tree.h (JOINER): Define joiner character the same way
11712 * ch-grant.c (chill_start_module_code): Use JOINER character
11713 to implement name mangling for the initializer function name.
11714 Algorithm is designed to be simple, distinct from C++ mangled
11715 symbols, and easy to convert to demangled form.
11717 Thu Dec 31 10:30:51 1992 Bill Cox (bill@rtl.cygnus.com)
11719 * ch-expr.c: make array assignments work with indirect refs.
11720 * ch-actions.c: prepare for array parameter handling.
11721 * ch-loop.c, ch-parse.y, ch-tree.def, ch-typeck.c: clean up.
11723 Thu Dec 31 15:29:20 1992 Per Bothner (bothner@rtl.cygnus.com)
11725 * ch-lex.l (yy_input): Re-write to return more than one
11726 character at a time (execpt when reading seize-files).
11727 Don't increment lineno until we start reading the next line.
11728 This fixes some off-by-one errors in lineno.
11730 Wed Dec 30 16:15:23 1992 Per Bothner (bothner@rtl.cygnus.com)
11732 * ch-convert.c: Assume use of new common.c.
11733 * ch-convert.c (convert_to_reference, convert_from_reference):
11734 New routines, to handle loc-identity declared variables and
11735 LOC parameters (both of which are implemented as references).
11736 * ch-lang.c (convert_to_boolean, convert_to_char): Move to
11737 ch-convert.c, where they would seem to belong.
11738 * ch-convert.c (convert): New function, since we no longer
11739 link in c-convert.c.
11740 * ch-expr.c (chill_expand_assignment): Handle by calling
11741 convert() instead of chill_comptypes().
11742 Also handle the LHS being a reference.
11743 * ch-parse.y: Add a procedure call as an action.
11744 * ch-parse.y (locdec, optlocinit): Move handling of
11745 loc-identity declarations from optlocinit to locdec
11746 - and add working semantics for it.
11747 * ch-parse.y (seizestatement, visibilty_stmt): Simplify.
11748 * ch-parse.y (grantstatement etc): Don't bother making list.
11749 * ch-lex.l: #include <sys/types.h> before <sys/stat.h>.
11751 Wed Dec 30 16:06:55 1992 Bill Cox (bill@rtl.cygnus.com)
11753 * ch-parse.y, ch-expr.c: add support for declaring & assigning
11755 * ch-typeck.c: allow VARYING structures in assign_type_to_expr.
11757 Tue Dec 29 15:28:48 1992 Bill Cox (bill@cygnus.com)
11759 * ch-actions.c: implement expressions of arrays of char,
11760 ( concatenation, relationals ), correct type of code parameters
11761 * ch-expr.c: correct type of code parameters
11763 Tue Dec 29 11:16:19 1992 Bill Cox (bill@cygnus.com)
11765 * ch-decl.c: cleanup.
11766 * ch-parse.y: put emit_line_note() calls in lotsa places,
11767 per Fred's request; be sure that statements get counted also.
11768 * ch-lex.l: standardize function headers.
11770 Tue Dec 29 10:41:56 1992 Fred Fish (fnf@cygnus.com)
11772 * ch-decl.c (start_chill_function): Always return 1, rather
11773 than a random value.
11774 * ch-lex.l (check_newline): Add a version for chill that
11775 just snarfs the right value for main_input_filename out of
11776 the first line of the input file, without disturbing the
11777 lexer state or requiring it's assistance.
11778 * ch-actions.c (lang_init): Call check_newline, like the
11779 other language frontends, to get main_input_filename set
11780 from first line of input file.
11782 Mon Dec 28 18:49:01 1992 Bill Cox (bill@cygnus.com)
11784 * ch-parse.y: clean up conflicts. The remaining one is
11787 Mon Dec 28 17:28:40 1992 Bill Cox (bill@cygnus.com)
11789 * ch-parse.y, ch-lex.l, ch-actions.c: add stubs for I/O,
11790 clean up some parser conflicts.
11792 Mon Dec 28 15:00:20 1992 Bill Cox (bill@cygnus.com)
11794 * ch-parse.y, ch-lex.l: add keywords and parsing for most of
11797 Sat Dec 26 20:48:23 1992 Fred Fish (fnf@cygnus.com)
11799 * chillrt/chillrt0.c: Oops, SVR4 doesn't need leading '_'
11800 on build_exceptions.
11802 Sat Dec 26 11:00:36 1992 Fred Fish (fnf@cygnus.com)
11804 * ch-grant.c (chill_finish_module_code): Call
11805 assemble_constructor_alias rather than assemble_constructor.
11806 * varasm.c (assemble_constructor_alias): New function,
11807 like assemble_constructor, but also handles the case where
11808 ASM_OUTPUT_CONSTRUCTOR is not defined and GNU ld is not
11809 being used. Emits a symbol table alias name with the correct
11810 prefix for collect to find and add to the __CTOR_LIST__.
11811 * chillrt/chillrt0.c: Build on previous hack that gets
11812 _build_exceptions into the __CTOR_LIST__, to make it work
11813 for both the non GNU-ld case and for the SVR4 case.
11815 Tue Dec 22 18:24:55 1992 Bill Cox (bill@cygnus.com)
11817 * ch-loop.c: clean up location enumeration - one more

11830 * ch-parse.y, c-decl.c: Add Jukka's Pascal WITH code.
11831 ch-loop.c: rough draft of location enumeration
11832 ch-lex.l, ch-expr.c, ch-decl.c: minor cleanup
11833 ch-actions.c: finish making pred() and succ() work.
11835 Mon Dec 21 10:04:35 1992 Bill Cox (bill@cygnus.com)
11837 * ch-actions.c: allow pred(char) and succ(char).
11839 Sun Dec 20 16:04:28 1992 Bill Cox (bill@cygnus.com)
11841 * ch-expr.c, ch-actions.c, ch-parse.y, ch-loop.c,
11842 c-expr.c: make DO WITH work.
11844 Sun Dec 20 12:22:53 1992 Bill Cox (bill@cygnus.com)
11846 * ch-loop.c, ch-actions.c, ch-typeck.c: powerset loops
11849 Sat Dec 19 14:20:23 1992 Per Bothner (bothner@cygnus.com)
11851 * c-typeck.c (process_init_constructor): Add warning if
11852 there is a duplicate default initializer element.
11853 * ch-typeck.c (chill_give_type_to_expr): New function,
11854 to handle coercion of an expression to context-given type,
11855 Takes care of untyped tuples, and case expressions.
11856 * ch-decl.c (do_decls), ch-typeck.c (chill_expand_return,
11857 chill_expand_result), ch-parse.y <assignaction>:
11858 Use chill_give_type_to_expr().
11859 * ch-typeck.c (chill_handle_case_label): New parameter list,
11860 to handle the (new) conventions for <case_label>, including
11861 default elements and ranges.
11862 * ch-parse.y <expanded_case_label>, ch-typeck.c
11863 (expand_case_expr): Use new version of chill_handle_case_label.
11864 * ch-decl.c (push_syndecls): Change parameters: Instead of
11865 TREE_LIST representing a compete <synonym definition statement>,
11866 just pass the parts of a single <synonym definition> as 3
11867 different parameters. Also, use chill_give_type_to_expr(),
11868 to handle untyped tuples in the RHS.
11869 * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct
11870 a tree - just call push_syndecls() on each <synonum_definition>
11872 * ch-parse.y (exprlist_get_single): Remove; no longer needed.
11873 * ch-parse.y: Handle <tuple> without mode name diferently from
11874 <tuple> with mode name. The latter is a <primval> that can be
11875 in most contexts, but if the <mode name> is missing, the <tuple>
11876 is only allowed in certain contexts. Use the new non-terminal
11877 <untyped_expr> to indicate those contexts where untyped tuples
11878 (and case expressions) are valid because the expression gets a
11879 type from its context (such as the RHS of an assignment).
11880 Use chill_give_type_to_expr in those contexts.
11882 Sat Dec 19 14:01:26 1992 Bill Cox (bill@cygnus.com)
11884 * ch-actions.c, ch-loop.c, Makefile.in: looping stuff.
11886 Sat Dec 19 10:16:20 1992 Bill Cox (bill@cygnus.com)
11888 * ch-parse.y: clean up warning messages from byacc. bison
11889 still complains thrice.
11891 Fri Dec 18 12:33:29 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11893 * ch-actions.c (maybe_chill_comptypes): Delete unused
11895 (chill_comptypes): Add new parameter ERRSTR. All callers
11897 (build_chill_binary_op): Fix indentation to match GNU coding
11900 Fri Dec 18 08:18:13 1992 Bill Cox (bill@rtl.cygnus.com)
11902 * ch-parse.y, ch-expr.c, ch-actions.c, expr.c: major

11912 a default initializer element.
11913 * ch-parse.y: Implement default elements for tuples
11914 (as in '(else):' and '(*):' ).
11916 * ch-parse.y: Previous change to dis-ambiguate case-labels
11917 seems to have allowed getting rid of all of the expr_or_list hair.
11918 * ch-decl.c (do_decls): Undo Tiemann's change to "Handle
11919 initialization of multiple variables by a tuple" - the
11922 Wed Dec 16 11:17:53 1992 Bill Cox (bill@cygnus.com)
11924 * ch-parse.y: complete re-write of DO statement handling.
11925 now operational, except WITH is stubbed out. Improved
11926 syntax error message.
11927 * ch-actions.c: DO support: high_domain_value(), low_domain_value ().
11928 * ch-expr.c: fixes to IN_EXPR handling.
11930 Tue Dec 15 17:15:13 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11932 * ch-grant.c: Add casts to alloca return to avoid compiler warning.
11933 * ch-lex.c: Likewise.
11935 * Makefile.in (ch-lex.c): Delete incorrect free declaration added
11936 by flex to avoid compiler error.
11938 Tue Dec 15 08:41:08 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11940 * ch-decl.c (do_decls): Handle initialization of multiple
11941 variables by a tuple.
11943 * ch-decl.c (do_decls,start_chill_function): Make DECL public
11944 if we're doing a GRANT ALL at top level.
11946 * ch-lang.c (build_range_type): Deal with typecast to CHAR in
11949 * c-typeck.c (digest_init): SET_TYPE is not a scalar type.
11950 BOOLEAN_TYPE and CHAR_TYPE are scalar types.
11952 Mon Dec 14 14:58:32 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11954 * ch-lex.l (get_chill_{linenumber,filename}): New functions.
11955 (convert_number): Use LONG_TYPE_NODE instead of INTEGER_TYPE_NODE.
11957 Mon Dec 14 13:36:44 1992 Bill Cox (bill@cygnus.com)
11959 * expr.c: install and test newer Pascal IN_EXPR code,
11960 but don't activate it - it's very verbose.
11962 Mon Dec 14 00:22:49 1992 Fred Fish (fnf@cygnus.com)
11964 * Makefile.in (LANGUAGES): Add chill.
11965 * Makefile.in (CHILL_INSTALL_NAME, CHILL_CROSS_NAME):
11966 New macros for chill native and cross installation names.
11967 * Makefile.in (COMPILERS): Add cc1chill.

11971 sublibchill.a, ch-parse.o, ch-parse.c ch-*.o, install-libchill,
11972 install-librmt): New targets.
11973 * Makefile.in (install-native): Add install-libchill,

11978 * ch-actions.c, ch-expr.c: Fix the pop-count in library calls.
11980 Sun Dec 13 14:07:32 1992 Bill Cox (bill@cygnus.com)
11982 * ch-actions.c: fix unary operations, modulus ops,
11983 (discovered after extending regression tests).

11987 * resync with Michael and Wilfried
11989 Sun Dec 13 09:11:25 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11991 * ch-parse.y (output_constant): Fixed some whitespace
11993 * ch-tree.h: Add declarations for new chill functions that
11994 have been implemented but not (yet) declared.
11996 Sat Dec 12 00:17:23 1992 Per Bothner (bothner@cygnus.com)
11998 * c-typeck.c (process_init_constructor): Warn about duplicate
11999 labels for labelled initializer elements.
12000 * ch-lex.l (various operator tokens, such as "+"): Don't
12001 set yylval.code to a TREE_CODE; this is better done in parser.
12002 * ch-parse.y: Some work with case labels and tuples.
12003 Get literal range as tuple (and case) labels working.
12004 Fix some problems introduced by recent grammar overhaul.
12006 Fri Dec 11 13:28:48 1992 Bill Cox (bill@cygnus.com)
12008 * ch-actions.c, ch-parse.y ch-tree.h ch-expr.c, ch-typeck.c:
12009 got long, real expressions working. We can also call a func-
12010 tion and use its return value.
12012 Thu Dec 10 14:45:17 1992 Per Bothner (bothner@cygnus.com)
12014 * ch-parse.y: Major change to remove or at least identify
12015 parser ambiguities. One result: We now allow actions that
12016 start with '(', as required by teh Blue Book. This does break
12017 some things; look for FIXME for things that need work.
12018 * ch-typeck.c (chill_expand_case_expr): We need an extra
12019 level of looping to (in the future) support <case label
12020 specification>s with more than one <case label list>.

12034 regression test and fix bit arrays and set ops.
12036 Mon Dec 7 14:57:46 1992 Bill Cox (bill@cygnus.com)
12038 * ch-actions.c: implement crude relationals between
12039 non-exotic operands, such as integers.
12041 Mon Dec 7 10:42:35 1992 Bill Cox (bill@cygnus.com)
12043 * ch-actions.c: implement relational, logic operations
12044 on arrays of BOOLs.

12048 * ch-actions.c (lang_init): Set LINENO to 1 at beginning to
12049 indicate we are done with initialization.
12051 * ch-decl.c (do_decls): Set TREE_PUBLIC if we are doing a
12053 (start_chill_function): Ditto.
12055 * ch-lex.c (convert_bitstring): Set TREE_CONSTANT.

12072 * tree.def: Move CARD_EXPR and SET_LE_EXPR back down with the other
12073 Pascal-required ones, since C++ no longer needs them. When
12074 Chill's public, a comment can be added to the effect that
12075 SET_LE_EXPR is also used by Chill.

12118 (push_newmode,push_synmode): Call `fixup_unknown_type' when we
12119 see a declaration that uses `unknown_type_node'. FIXME.
12121 * ch-grant.c (decode_constant): New function.
12122 (decode_decl): Call `decode_constant' for CONST_DECLs.
12124 * ch-lex.l (char action): Use ridpointers instead of
12125 lookup_name to get "char"'s declaration.
12127 * ch-parse.y: Call `build_lang_decl' instead of `build_decl'
12128 when we need to build a TYPE_DECL.
12130 Tue Dec 2 09:44:05 1992 Bill Cox (bill@cygnus.com)
12132 * ch-typeck.c: clean up a gcc warning with a forward
12133 declaration of build_string_type.

12138 that are duplicated in c-decl.c
12140 Tue Dec 1 16:38:51 1992 Fred Fish (fnf@cygnus.com)
12142 * ch-actions.c (lang_init): Ifdef out initializations for
12143 __builtin_abs and __builtin_fabs, since they are duplicates of
12144 initializations in c-decl.c, and trigger spurious warnings.
12146 Tue Dec 1 16:35:18 1992 Bill Cox (bill@cygnus.com)
12148 * ch-parse.y: make size() work with a typename argument.

12175 Mon Nov 30 17:35:33 1992 Fred Fish (fnf@cygnus.com)
12177 * chillsh: New script frontend (ala g++), installed as "chill".
12178 Can't be called "chill.sh" because make tries to cat it into the
12179 "chill" directory. Can't be called just "chill" cause that's
12180 already there as a directory.
12181 * Makefile.in: Add rules to install chillsh as "chill".
12182 * chill/libchill.c: Temporarily ifdef out stuff that wants
12183 to conflict with i486/SVR4 runtime or wants to pull in librmt.a,
12184 which itself causes linkage to fail.
12186 Mon Nov 30 16:28:19 1992 Bill Cox (bill@cygnus.com)
12188 * ch-lex.l: added keywords for TRUNC, ROUND, FLOAT, LFLOAT
12189 conversion routines.
12190 * ch-parse.y: added %tokens for TRUNC, ROUND, FLOAT, LFLOAT.
12191 Added production for SIZE(expr).

12196 * ch-lex.l, ch-parse.y: Translate token PFEIL into English ARROW.
12197 * ch-parse.y (op6): Remove handling of string repetition operator,
12198 until we can figure out a way to parse it correctly.

12200 * ch-parse.y (tuple): Merge the two variants using optmodename.
12201 * ch-parse.y (location): Add semantic actions for
12202 dereferencing operator ->.

12206 * ch-actions.c: removed compile warning, better code for abs.
12208 * ch-parse.y: add productions for builtin functions succ, pred,
12209 abs, and size. Add %tokens also. Sort %tokens alphabetically.
12211 * ch-lex.l: add parsing for builtin function names, such as abs,
12212 pred, succ, etc. Put flex -a option into Makefile.in, so we can
12213 clean up the lexer soon.
12215 Tue Nov 24 14:18:48 1992 Per Bothner (bothner@rtl.cygnus.com)
12217 * ch-typeck.c (chill_handle_case_label, chill_handle_case_default):
12218 New functions, for code common to CASE actions and expressions.
12219 * chill.y: Replace some code by calls to chill_handle_case_label
12220 and chill_handle_case_default.
12221 * ch-typeck.c (chill_expand_case_expr): Add semantics.
12223 * tree.c: Change doing_chill_thang from extern to common.

12227 * ch-tree.def: New CASE_EXPR type, for case expressions.
12228 * ch-expr.c (chill_expand_expr): Hook for CASE_EXPR.
12229 * ch-typeck.c (chill_expand_case_expr): New function.
12230 Placeholder to implement case expressions.
12231 * ch-typeck.c (chill_expand_result, chill_expand_return):
12232 Handle mode-unspecified tuples and case expressions in
12233 the context of RETURN and RESULT actions.
12234 * chill.y (assignaction): Handle case expressions in the
12235 context of the RHS of an assignment action.
12236 * chill.y (caseaction): Remove spurious duplicate OF in grammar.
12237 * chill.y: Handle labeled structure tuples.
12238 * chill.y: New rules to parse CASE expressions.
12239 * tree.c (build_function_types): Allow Chill functions
12240 to return arrays and functions.
12242 Wed Nov 18 13:50:28 1992 Per Bothner (bothner@rtl.cygnus.com)
12244 * ch-typeck.c (chill_expand_tuple): New function. Expand a
12245 tuple (constructor) given an expected (context) type.
12246 * chill.y: Implement 'LHS := TUPLE' using expand_chill_tuple,
12247 using the mode of the LHS and the expected type of the TUPLE.
12248 * chill.y: Implement initialization.
12249 * chill.y: Fix some syntax bugs (forbidlist must be surrounded
12250 by parentheses), and remove or note ambiguities.
12251 * chill.y: Started converting layout style to be like c-parse.in.
12252 * chill.y: Implement IF expressions.
12253 * chill.y: Added syntax rules for tuples. Labelled and unlabelled
12254 array tuples should now work (in some contexts).
12255 * ch-actions.c: Initialize doing_chill_thang to 1.
12256 * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
12257 initializer, to make pushdecl and finish_decl work.
12258 * c-decl.c (convert_for_assignment): If Chill, don't convert
12259 function and arrays into pointers. (Maybe functions should
12260 still be converted?)
12261 * c-typeck.c (grokdeclarator): Allow functions in Chill
12262 to return arrays and functions.
12264 Mon Nov 16 15:40:47 1992 Per Bothner (bothner@rtl.cygnus.com)
