3315 bit-string, bit_one_node and bit_zero_node were switched.

3488 * except.c (emit_setup_handler): Add a cleanup to
3489 unlink from exception stack if we return/exit/goto from here.
3490 * loop.c (begin_loop_scope): Move pushlevel from here ...
3491 * parse.c (parse_do_action): ... to here.

3509 * lex.l (readstring): Add processing of control sequence
3510 in character string literals. The granting mechanism writes
3511 this to grant files.

3515 * expr.c (compare_records): In case of -fpack do always
3516 a memcmp instead of comparing each field of the

3529 (add_taskstuff_to_list): Add a new argument, which is
3530 the entrypoint of a process.
3531 (build_process_header): Change PROCESS arguments to be
3532 like arguments of a function. There will be a wrapper
3533 which is the real entry point for a PROCESS. This wrapper
3534 is automatically build after a PROCESS definition and gets
3535 as argument a pointer to a structure looking like the
3536 arguments of the PROCESS. This wrapper will call the
3537 PROCESS (see build_process_wrapper).
3538 (build_process_wrapper): New function (see above).
3539 (build_start_process): Change processing of arguments.
3540 (tasking_setup): Add processing of a different entry point

3550 of PROCESSes, they look now like normal functions.
3552 * decl.c (init_decl_processing): Add declaration of memcmp

3569 * Makefile.in (GNUCHILL_VERSION): Remove it, its defined in
3572 * chill.in: In case of -fgrant-only pass "-S -o /dev/null"
3573 to the compiler to avoid generation of an object file.
3575 Thu Sep 8 12:07:28 1994 Per Bothner (bothner@kalessin.cygnus.com)
3577 * convert.c (display_int_cst), ch-tree.h: New function.
3578 * convert.c (digest_array_tuple): Use digest_int_cst to
3579 provide better error messages. Return error_mark_node on error.
3580 * grant.c (decode_const): Simplify by using digest_int_cst.
3581 * grant.c (format_character, find_assoc): Removed.
3583 * decl.c (do_decl): Add missing TREE_CHAIN.
3585 * decl.c (finish_incomplete_decl): Removed.
3586 (init_decl_processing): Don't set incomplete_decl_finalize_hook.
3587 (finish_decl): Remove old C-specific code to deduce size of
3588 array from initialization.
3589 (complete_array_type): Just make it abort.
3591 * except.c (finish_handler_array): Avoid calling C-specific kludge
3592 complete_array_type.
3594 * convert.c (digest_constructor): Rename, and re-write to:
3595 (digest_array_tuple, convert): No longer use the code in
3596 ../c-typeck.c; use a Chill-only implementation (sigh).
3598 * typeck.c (chill_expand_tuple): Remove unneeded call to
3599 complete_array_type.
3601 * expr.c (fold_set_expr), grant.c (decode_constant),
3602 typeck.c (expand_constant_to_buffer): Update name of called
3603 function unpack_set_constructor to get_set_constructor_bits.
3604 * expr.c (powersetlen ): Remove redundant call to convert.
3606 * ch-tree.h (unpack_set_constructor): Removed obsolete declaration.
3608 * inout.c (build_chill_writetext): Handle 64-bit integer literals
3609 by trying to convert them to a smaller type.
3611 * lex.l (convert_number): Always use long long type (possibly
3612 unsigned) to avoid problems with constant folding truncation.
3614 Mon Sep 5 08:08:22 1994 Wilfried Moser (moser@rtl.cygnus.com)
3616 * ch-tree.h (enum chill_built_in_function): Add BUILT_IN_QUEUE_LENGTH.

3619 * expr.c (build_generalized_call): Add processing of
3620 BUILT_IN_QUEUE_LENGTH.
3622 * tasking.c (build_queue_length): New function.
3624 * tasking.c (tasking_init): Add new external function definition.
3626 Thu Sep 1 15:38:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3628 * lex.l (default_lex): New function. Progress towards
3629 getting rid of [f]lex.
3631 * lex.l (convert_number): Use mul_double and add_double.
3632 Set result type to a reasonable type in which the literal
3633 will fit. Give error message if literal is too big.
3635 * lex.l (equal_number): Switch (temporarily) to permanent obstack.
3637 * typeck.c (build_chill_slice_with_range): Check for empty
3638 slice *after* we have checked for upper/lower limit in range.
3640 * grant.c (decode_mode): Remove unused code. (BOOL and
3641 CHAR ranges are represented as INTEGER_TYPEs.)
3643 * tasking.c (build_process_header): Add missing call to
3644 expand_start_bindings.
3645 * parse.c (end_function): Add missing expand_end_bindings.
3647 Wed Aug 31 17:25:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3649 * decl.c (init_decl_processing): Set set_alignment.
3651 Tue Aug 30 16:40:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
3653 * actions.c (print_missing_cases, check_missing_cases,
3654 BITARRAY_TEST, BITARRAY_SET): New functions and macros,
3655 to check for completeness of case actions and expressions.
3656 * decl.c (c_decode_option, init_decl_processing):
3657 Don't set warn_switch.
3658 * expr.c (chill_expand_case_expr): Call check_missing_cases
3659 instead of check_for_full_enumeration_handling.
3660 * parse.c (parse_case_actions): Call check_missing_cases.
3662 * expr.c (build_chill_binary_op): Remove some dead code.
3663 * expr.c (chill_truthvalue_conversion): Call build_chill_binary_op
3664 instead of build_binary_op.
3665 * ch-tree.h (binary_op_error, build_binary_op): Unused. Removed.
3667 * parse.c (end_function): Use kept_level_p in parameter to
3668 poplevel. This reverts a June 13 change.
3670 Fri Aug 26 11:50:19 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3672 * configure: Ignore --without, as ../configure does.
3674 Wed Aug 24 01:17:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3676 * lex.l: Change rule for decimal numbers to allow identifiers
3677 to start with an underscore (_).
3679 Fri Aug 19 16:38:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
3681 * tasking.c (build_receive_signal_case_label): Remove backwards
3682 chill_convert_for_assignment (which converted whatever garbage
3683 was in the *target* to the type of the signal argument!).
3685 Fri Aug 19 07:10:43 1994 Wilfried Moser (moser@rtl.cygnus.com)
3687 * inout.c (build_chill_io_list_type, build_enum_tables),
3688 tasking.c (build_tasking_struct): Temporarily reset
3689 maximum_field_alignment to 0, so that the compiler-built
3690 data structures needed by the RTS can be independent of -fpack.
3692 Thu Aug 18 13:39:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3694 * typeck.c (build_init_struct): Temporarily reset
3695 maximum_field_alignment to 0, so that the compiler-built
3696 data structures needed by the RTS can be independent of -fpack.
3698 Wed Aug 17 23:48:33 1994 Wilfried Moser (moser@rtl.cygnus.com)
3700 * parse.c (parse_primval, expect, parse_on_exception_list):
3701 Print error message only in pass 2.
3703 Wed Aug 17 13:47:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3705 * decl.c (switch_to_pass_2): Revert June 13 change,
3706 (Don't exit after pass 1 if an error was found.)
3708 * ch-tree.def (SLICE_EXPR): New tree-code.
3709 * typeck.c (build_chill_slice): For building a slice of a
3710 bit-string, just generate a SLICE_EXPR.
3711 * decl.c (init_decl_processing): Declare __pscpy.
3712 * actions.c (chill_expand_assignment): Handle a SLICE_EXPR
3713 on the LHS of assignment, by calling __pscpy.
3714 * expr.c (chill_expand_expr): Handle SLICE_EXPR (as a RHS
3715 value) by using __psslice to copy slice to a temp.
3717 Wed Aug 17 05:52:44 1994 Wilfried Moser (moser@rtl.cygnus.com)
3719 * Make-lang.in: Change version of GNUCHILL compiler to 1.4.1.
3720 * expr.c (build_chill_length): Enable LENGTH built-in to process
3721 Buffers and Events too (Z.200/1992).
3722 * lex.l (yywrap): Always set yyin to finput and/or grt_in. On
3723 a linux system the previous version was not able to run.
3724 * tasking.c: Correct processing of infinite buffer- and event-length
3725 to avoid RANGEFAIL warning.
3727 Thu Aug 11 11:46:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3729 * parse.c (parse_if_expression_body): Don't call the C-specific
3730 build_conditional_expr. Just do build_nt (COND_EXPR, ...).
3731 * convert.c (convert): Convert a COND_EXPR by converting
3734 * convert.c (convert): Don't call convert before
3735 convert_to_reference. It's apt to do weird and unneedful things.
3736 * convert.c (convert): If the expression is varying, just call
3737 varying_to_slice, which simplifies quite a bit.
3739 * ch-tree.h (varying_to_slice): Add prototype.
3740 * typeck.c (varying_to_slice): Remove prototype.
3742 * satisfy.c (satisfy): Move case PAREN_EXPR from type 'e'
3745 * except.c (emit_setup_handler): Temporarily reset the
3746 maximum_field_alignment to zero so the compiler's exception
3747 data structures can be compatible with the run-time system,
3748 even when we're compiling with -fpack.
3750 * expr.c (compare_records): Call saved_if_needed on operands.
3752 * expr.c (build_set_expr case NE_EXPR): Don't use __nepowerset
3753 which has been reimplemented to just call __eqpowerset and
3754 invert the result. Inline this new implementation by
3755 handling as EQ_EXPR, and inverting the result.
3756 * decl.c (init_decl_processing): Don't define unused __eqpowerset.
3758 * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
3759 type boolean_type_node, not void_type_node. (Fixing this
3760 avoids a crash in the back-end.)
3762 * grant.c (decode_constant): In a CALL_EXPR, if the argument
3763 list is not a TREE_LIST (as in string repetiation), don't
3766 Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3768 * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
3769 CONST_DECL is from a SET definition. (This is safer than
3770 checking that the type is ENUMERAL_TYPE, because synonym
3771 definitions may have a NULL TREE_TYPE.)
3772 Also, if we have duplicate enums whose types are identical,
3774 * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
3775 an extra 'quiet' parameter, which is true if we're called from
3776 bind_sub_modules. (In that case an error message about duplicated
3777 decls would be repeated later, so suppress it.)
3779 * parse.c (stmt_count): Removed, not used.
3780 (INIT_ACTION): Call emit_line_note only if !ignoring.
3781 (parse_begin_end_block): Do INIT_ACTION even if ignoring.
3783 Fri Aug 5 12:39:11 1994 Per Bothner (bothner@kalessin.cygnus.com)
3785 * parse.c (parse_untyped_expr): Add missing semi-colon.
3787 Thu Aug 4 17:40:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
3789 * parse.c (parse_untyped_expr): Fix various problem for the
3790 case that we see a '(': Add missing 'case' keyword.
3791 Only recurse if '(' is followed by 'if', 'case' or '[',
3792 and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
3794 * parse.c (parse_send_action): Remove extra nreverse.
3796 Thu Jul 28 04:00:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3798 * expr.c (build_allocate_global_memory_call, build_allocate_memory_call):
3801 Tue Jul 26 22:48:15 1994 Michael Tiemann (tiemann@blues.cygnus.com)
3803 * parse.c (parse_untyped_expr): Added missing "case" before LPRN.
3804 Added a missing call to `require' as well.
3806 Tue Jul 19 10:30:12 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3808 * lex.l (yywrap): Define as yywrap_chill to avoid conflicts with
3809 the extern declaration in the flex skeleton.
3811 Mon Jul 18 23:06:04 1994 Per Bothner (bothner@kalessin.cygnus.com)
3813 * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
3814 Check the type of the instance expr using CH_COMPATIBLE,
3815 and not just == instance_type_node. (This allows
3816 the expression to have mode READ INSTANCE).
3817 * tasking.c (build_instance_type): Give instance_type_node
3818 a non-null novelty (i.e. different from a struct).
3819 * tasking.c (build_receive_case_start, build_delay_case_start):
3820 Check that for a location using CH_LOCATION_P.
3822 Mon Jul 18 13:22:23 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
3824 * expr.c (finish_chill_unary_op): Use TREE_SET_CODE not TREE_CODE
3825 to modify a tree code.
3827 Mon Jul 18 11:24:57 1994 Bill Cox (bill@rtl.cygnus.com)
3829 * convert.c (digest_structure_tuple): Fix thinko in TREE_CODE
3832 Mon Jul 18 05:40:15 1994 Doug Evans (dje@canuck.cygnus.com)
3834 * decl.c (warn_bad_function_cast): Define so cc1chill will link.
3836 Thu Jul 14 18:37:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3838 * parse.c (parse_send_action): Do tree_cons *before* checking
3841 Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3843 * convert.c (digest_structure_tuple): Don't use convert to
3844 coerce initial value, use chill_convert_for_assignment instead.
3845 (Thus we also get range_checking.)
3847 * expr.c (build_chill_card): Use force_addr_of instead of
3848 build_chill_addr_expr.
3850 * loop.c (build_temporary_variable): Stylistic tweak.
3851 * loop.c (maybe_make_for_temp): Initialize temp using
3852 explicitly, not using assignment. Avoids a problem if
3853 the expression is read-only.
3854 * typeck.c (smash_dummy_type): Always used the saved TYPE_NAME
3855 and CH_NOVELTY_FLAG.
3857 Wed Jul 6 20:12:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3859 * expr.c, ch-tree.h (finish_chill_unary_op): New function,
3860 based on code ripped out of build_chill_unary_op.
3861 (build_chill_unary_op): Call finish_chill_unary_op unless pass==1.
3862 * satisfy.c (satisfy): Call finish_chill_unary_op when needed.
3864 Mon Jun 27 11:29:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3866 * tree.c (save_if_needed), ch-tree.h: New function.
3867 * typeck.c (build_chill_slice_with_range,
3868 build_chill_slice_with_length): Call save_if_neeed on array arg.
3869 * expr.c (varying_to_slice): Re-write to use save_if_needed.
3871 * typeck.c (extract_constant_from_buffer): Handle BOOLEAN_TYPE.
3873 Mon Jun 27 01:11:10 1994 Wilfried Moser (moser@rtl.cygnus.com)
3875 * inout.c (build_chill_io_list_type): Change layout of __tmp_WIO_list
3876 that it is always the same, regardless if compiled with -fpack
3879 Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3881 * lex.l (yywrap): Kludge to work around mis-synchronization
3882 between lexer (which read ahead) and parser: Don't emit
3883 (left-over) uze_seizefile directives at the end of file.
3885 * typeck.c (build_chill_array_ref): Allow the derived
3886 array indexing syntax for arrays of bit strings.
3887 Add a comment explaining why.
3889 * typeck.c, ch-tree.h (string_assignment_condition): Change
3890 the interface. Return a boolean expression (which can be
3891 used in a conditional at run-time); never expand anything.
3893 * actions.c (chill_convert_for_assignment): Check
3894 string_assignment_condition here, rather than in callers.
3895 * actions.c (chill_expand_assignment): Don't need to check
3896 string_assignment_condition here.
3897 * expr.c (build_chill_function_call): Likewise.
3898 * satisfy.c (safe_satisfy_decl): Update accordingly.
3899 * decl.c (do_decl): Simplify testing and conversion by
3900 deferring everything to chill_convert_for_assignment.
3902 * parse.c: Combine the two variables 'ignore_exprs' and
3903 'ignore_actions' into one variable called 'ignoring'.
3904 * ch-tree.h: Add 'extern int ignoring'.
3905 * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
3906 Rename ignore_actions and ignore_exprs to ignoring.
3907 Remove unneeded extern declarations.
3908 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3909 build_chill_arrow_expr, build_generalized_call, build_delay_action,
3910 build_buffer_type, build_event_type): I changed my mind. It is
3911 cleaner to check for 'ignoring' in the parser, rather than here.
3912 * parse.c (parse_action, parse_primval, parse_opt_mode):
3913 Therefore we must check for ignoring here.
3914 * parse.c (parse_loc_declaration): Set ignoring in pass 2
3915 when parsing the mode.
3917 * tasking.c (generate_tasking_code_variable): Do arithmetic
3918 on signal_code etc using unsigned rather than signed shorts.
3920 * grant.c (static char* current_grant_modename): Removed.
3921 * grant.c (decode_decl case CONST_DECL): Remove error message.
3923 * Make-lang.in (CHILL_SRCS): Add $(srcdir)/ch/parse.c.
3924 * Makefile.in: Fix dependencies for parse.o.
3925 Remove some duplicate dependencies for $(TREE_H).
3927 Mon Jun 13 14:25:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3929 * typeck.c (build_chill_cast): Allow a value cast between
3930 non-discrete object of the same size, but with a pedwarn.
3931 * typeck.c (bit_string_assignment_condition,
3932 char_string_assignment_condition): Merge near-duplicate functions
3933 and place the code in string_assignment_condition.
3935 * decl.c (parm_flag, declare_parm_level, in_param_level_p):
3937 * decl.c (start_chill_function, finish_chill_function): Make
3938 parameter level have same nesting level as body, as required by Z200.
3939 * decl.c (switch_to_pass_2): Always exit if an error has been found.
3940 * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
3941 generated from GRANT ALL.
3942 * decl.c (lookup_name_for_seizing): Don't seize from
3943 the nesting level of builtins (predefined objects).
3944 * decl.c (lookup_name_for_seizing): Make more robust on error.
3946 * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
3947 be 'RESULT' (or 'result'). This makes it more accessible from gdb.
3948 Also, use do_decl to declare it, so that debugging symbols are
3949 generated. And, re-arrange so that actions that need to
3950 be done both passes (such as push_levels) use the same code.
3952 * parse.c (get_type_of): If ignore_exprs, don't lookup name.
3953 * parse.c (end_function): Fix poplevel params.
3954 * parse.c (expect): Don't read forwards on an error.
3955 * parse.c (parse_field): Don't define two tag_list locals!
3956 * parse.c (parse_pass_1_2): Better error message.
3958 * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
3959 parse_opt_mode, rather than vice versa. If parse_opt_mode
3960 returns NULL_EXPR, then parse_mode gives an error.
3961 Change parse_opt_mode (and any functions it calls) to only
3962 return NULL_TREE if there is no mode (even on ignore_exprs).
3963 (parse_set_mode, parse_structure_mode, parse_procedure_mode):
3964 Never return NULL_EXPR.
3965 * tasking.c (build_buffer_type, build_event_type): Return
3966 void_type_node instead of NULL_EXPR if ignore_exprs is true.
3968 * parse.c (parse_synonym_definition): Call parse_untyped_expr
3969 only if we have a mode.
3970 * parse.c (parse_send_action): Parse list of untyped_expr's,
3971 rather than a list of (typed) expressions.
3972 * parse.c (parse_primval): Emit error if '[' seen without
3973 preceding mode name. (If this is to be allowed, call
3974 parse_untyped_expr instead.)
3976 * parse.c (parse_array_index): Renamed to ...
3977 (parse_index_mode): ... to match Z200 terminology.
3978 Re-write to resolve some of the nastier ambiguities,
3979 and allow things like ' CHAR(10) : CHAR(20) '.
3981 * parse.c (parse_tuple_element): Change interface to return
3982 reversed list, so don't call nreverse.
3983 * parse.c (parse_tuple): No longer nreverse element list here.
3984 * parse.c (parse_opt_element_list): Do nreverse here instead.
3985 * parse.c (parse_case_label_list): Call nreverse at end.
3987 Fri Jun 10 15:36:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
3989 * typeck.c (chill_similar): Remove bogus "else".
3991 Wed Jun 8 00:01:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
3993 * ch-tree.h (TYPE_ARRAY_MAX_SIZE): New macro (and comment)
3994 to make it clearer that we are using TYPE_MAX_VALUE in a special way.
3995 * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
3996 * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
3997 * convert.c (convert): When converting a fixed string/array
3998 to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
3999 of (the type of) the padding.
4000 * convert.c (convert): If the concatenation is non-constant, use
4001 the low-level 'build' to set the type of the result (which is usually
4002 a fixed-size array) rather than depend on build_chill_binary_op
4003 to figure it out (it's unable to simplify the size to a constant).
4005 Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
4007 * lang.c (lang_decode_option): Let -fspecial_UC imply
4008 -fno-ignore-case without requiring it explicitly.
4009 * lang.c (lang_decode_option): Support (experimentally)
4010 the -fpack and -fno-pack flags.
4012 Thu Jun 2 20:49:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4014 * configure: Add support for --program-prefix and --program-suffix.
4016 Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
4018 * convert.c (digest_constructor): Check that initial value
4019 is compatible with element mode before calling convert.
4020 * typeck.c (chill_compatible): A string mode is not compatible
4021 with an untyped constructor.
4022 * decl.c (do_decl): Clean up error messages. Use error_with_decl.
4024 * ch-tree.h: Fix inconsistencies: bool_true_node ->
4025 boolean_true_node, and bool_false_node -> boolean_false_node.
4026 * typeck.c (valid_array_index_): Minor simplification.
4028 Tue May 31 04:33:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
4030 * inout.c (build_chill_writetext): Add correct processing
4031 of POWERSET RANGE (setmode).
4033 * lex.l (same_file): Add searching for file(s) in
4036 Fri May 27 14:22:42 1994 Per Bothner (bothner@kalessin.cygnus.com)
4038 * Make-lang.c (CHILL.mostlyclean, CHILL.distdir): Don't list
4039 yacc/bison output files, since the grammer is no longer in yacc.
4040 * config-lang.in (diff_excludes): Likewise.
4042 Thu May 26 16:38:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
4044 * gperf, hash.h, lex.l, parse.h: Rename PROCESS_TYPE token
4045 (in some files spelled PROCESS_TYPE_ to avoid clashes
4046 with the PROCESS_TYPE tree_code) to PROCESS_TYPE_TOKEN.
4048 Thu May 26 02:18:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
4050 * timing.c (build_cycle_start): Change call to __define_timeout.
4051 * decl.c (init_decl_processing): Change definitions of
4052 __define_timeout and __wait_timeout.
4054 Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
4056 Replace yacc-based parser with a recursive-decent parser.
4057 (This may seem backwards, but Chill [like C++] is not a
4058 language that is remotely LALR(1). Using a R-D parser
4059 allows us to use look-ahead and to back-up to resolve the
4060 difficult ambiguities.)
4062 * parse.c, parse.h: New files, containing new r-d parser.
4063 * Makefile.in: Update accordingly.
4064 * actions.c (chill_convert_for_assignment): Don't return
4065 NULL_EXPR if ignore_exprs is true. It simplifies the parser
4066 if we consistently reserve NULL_EXPR for a missing expression.
4067 * expr.c (build_chill_function_call): Likewise.
4069 * lex.l: Tweaks for new parser.
4070 * lex.l (prepare_paren_colon, paren_paren_colon_level,
4071 paren_level): Ugly hack no longer needed.
4073 * expr.c (build_chill_function_call): Cleanup.
4074 Call chill_convert_for_assignment to convert IN/INOUT
4075 paramaters on both input and output. For LOC parameters,
4076 give error if actual is a non-referable location.
4077 * actions.c (convert_for_assignment): Add new parameter (a
4078 "place" string used in error messages).
4079 * actions.c (adjust_parm_or_field): Removed.
4080 * actions.c (chill_expand_assignment): Take just a single LHS,
4081 and move support for multiple assignments to ...
4082 (expand_assignment_action): ... here. Some cleaning up.
4083 * timing.c (build_cycle_start): Adjust accordingly.
4084 * actions.c (expand_assignment_to_varying_array): Likewise.
4085 * tasking.c (many places): Ditto.
4086 * ch-tree.h: Fix declarations appropriately.
4088 * parse.c (parse_defining_occurrence_list): Return a single
4089 IDENTIFIER_NODE (instead of a singleton list) in the common
4090 case. Minor complication to save a minor amount of space.
4091 * decl.c (do_based_decls): Move guts of code into ...
4092 (do_based_decl): ... this new function.
4093 * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
4094 * decl.c (push_syndecl): Replace by ...
4095 (push_syndecl): ... (which only supports a single name).
4096 (push_modedef): Only handle a single name.
4097 * tasking.c (build_process_header, build_signal_struct_type):
4100 * expr.c (build_generalized_call): Handle string repetition.
4101 * expr.c (build_chill_repetition_op): Change interface.
4102 * grant.c (decode_constant): Allow parameter list to be
4103 a non-TREE_LIST. (Used for string repetition.)
4105 Wed May 25 11:28:48 1994 Per Bothner (bothner@kalessin.cygnus.com)
4107 * lex.l (make_identifier): Replaced by ...
4108 (read_identifier, handle_name): ... new functions.
4109 * lex.l: Parse an identifiers using read_identifier using
4110 read_identifier and handle_name, rather than having [f]lex
4111 do it. (One reason is that lex uses a fixed-size buffer.)
4113 * lex.l (read_directive, skip_directive): New functions.
4114 Use them to parse compiler-directives, instead of rather
4115 ugly and useless use of lexer start conditions.
4117 Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4119 * decl.c (unnamed_module_number): Renamed to ...
4120 (module_number): .. and make non-static.
4121 (push_module): Always increment module_number.
4122 * lex.l (yywrap): Print warning if no modules seen.
4124 * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
4125 decl to current_seizefile_name (which is unreliable).
4126 * grant.c (chill_grant): Set it here instead.
4128 * expr.c (fold_set_expr): Use int_size_in_bytes instead of
4129 TYPE_PRECISION (which is not defined for a SET_TYPE).
4131 Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
4133 Cleanup to remove need for variables in common storage.
4134 * decl.c: Remove unused use of current_obstack.
4135 * actions.c (maybe_chill_check_decl): Remove unused function.
4136 * actions.h, lang.c: Remove uses of doing_chill_thang.
4137 * ch-tree.h (void_list_node): Make extern (rather than common).
4138 * decl.c (void_list_node): Add definition.
4140 Thu May 19 06:54:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
4142 * configure (build): Build canon_host and canon_target
4143 to pass it to all subsequently generated Makefiles (needed
4144 for testsuite/execute in case of cross build).
4146 Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4148 * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
4149 the input type, which loses with the no-longer-new 2-pass
4150 implementation, since the input "type" could be an IDENTIFIER_NODE.
4151 * grant.c (raw_decode_mode): Rename to decode_mode.
4153 Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
4155 * typeck.c (chill_location): Neither a STRING_CST nor a
4156 CONSTRUCTOR is a location.
4157 * typeck.c (chill_root_mode): Convert a function to a
4158 pointer-to-function.
4159 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
4160 build_chill_arrow_expr): If ignore_exprs, return operand
4161 rather than NULL_EXPR. This makes it easier for the parser to
4162 distinguish missing expressions.
4163 * expr.c (build_max_min): Convert the lower bound of a
4164 set to a long before calling run-time routine.
4165 * expr.c (build_chill_pred_or_succ): Use discrete_type_p
4166 to check the argument type.
4167 * expr.c (build_chill_arrow_expr): If argument is not a location,
4168 do a predwarn if it is a STRING_CST or has function type.
4170 Tue May 17 06:05:13 1994 Wilfried Moser (moser@rtl.cygnus.com)
4172 * configure (build): Remove building of canon_host and canon_target.
4173 It doesn't work in any case.
4175 Mon May 16 02:10:35 1994 Wilfried Moser (moser@rtl.cygnus.com)
4177 * configure (build): Build canon_host and canon_target
4178 to pass it to all subsequently generated Makefiles (needed
4179 for testsuite/execute in case of cross build).
4180 * Make-lang.in (chill-runtime): Change chill to CHILL in the case
4181 statement to build chill-runtime automatically.
4183 Mon May 9 15:30:08 1994 Doug Evans (dje@canuck.cygnus.com)
4185 * Makefile.in (FLAGS_TO_PASS): Define.
4187 (../cc1chill): Depend on $(OBJDEPS) $(C_OBJS).
4188 * Make-lang.in (cc1chill): Delete dependency on $(OBJS) $(BC_OBJS).
4189 (CHILL.mostlyclean): Use `mostlyclean' as recursive target.
4191 Sun May 8 13:05:00 1994 Per Bothner (bothner@cygnus.com)
4193 * Make-lang.in (cc1chill): Should not depend on libgcc.a.
4195 Thu May 5 18:58:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
4197 * decl.c (copy_lang_decl): New (dummy) function.
4199 Mon May 2 14:33:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
4201 * parse.y (sendaction): Fix thinko (in sense of condition).
4202 * tasking.c (build_receive_case_label): Another thinko.
4204 * parse.y (optsigdest): Force ignore_exprs to 0 while parsing
4207 * decl.c (build_chill_function_type): Don't call layout_type
4208 (since that may prevent parameter or result types being
4209 properly satisfied).
4210 * satisfy.c (satisfy): Layout FUNCTION_TYPEs.
4211 * parse.y (procmode): Call build_chill_pointer_type, rather
4212 than build_pointer_type (which incorrectly sets TYPE_SIZE).
4214 * parse.y (get_type_of): Handle TYPE_DECL (again).
4215 * parse.y (optresultspec): Call build_chill_reference_type, rather
4216 than build_reference_type (which incorrectly sets TYPE_SIZE).
4217 * parse.y (range_or_mode): Rename to plain range, since it
4218 no longer matches modename.
4219 * actions.c (chill_handle_case_label_range): New function, with
4220 functionality moved out of chill_handle_case_label.
4221 * actions.c (chill_handle_case_label): Handle here the case that
4222 the label_value is a TYPE_DECL (modename). Also clean up some.
4223 * typeck.c (build_chill_slice_with_length): Convert max_index
4224 to the type of min_value. (Old code broke on varying strings.)
4226 Sun May 1 13:53:36 1994 Doug Evans (dje@canuck.cygnus.com)
4228 * Makefile.in (BC_OBJS): Delete all references
4229 (OBJS): Cat ../stamp-objlist to get language independent files.
4230 (../cc1chill): Delete dependency on $(OBJS).
4231 * Make-lang.in (cc1chill): Depend on stamp-objlist.

4235 * lex.h, lex.c: Remove lastiddecl.
4236 * lex.l (name_type_signal): Simplify. We no longer check for
4237 TYPENAME or SIGNALNAME (which was unreliable with two passes).
4238 Also rename to make_identifier.
4239 * parse.y: Cleaned up grammar to not need SIGNALNAME or TYPENAME.
4240 * Makefile.in (stamp-parse); One conflict fewer!
4241 * parse.y (rccase_label_flag): Moved to tasking.c.

4243 build_receive_case_label in tasking.c.
4244 * parse.y (sendaction): Re-write to not depend on SIGNALNAME.
4246 * parse.y (name): Do name lookup here (and not in location).
4247 * parse.y: Replace most uses of NAME by higher-level non-terminals:
4248 simple_name_string, name_string, defining_occurrence, or name.
4250 * tasking.c (build_receive_signal_case_label,
4251 build_receive_buffer_case_label): New functions, split out from
4252 build_receive_case_label.
4253 * tasking.c (build_receive_case_label): Change parameters
4254 and return type. Moved stuff here (from the parser).
4255 * tasking.c (struct rc_state_type): Removed had_errors.
4256 Return error_mark_node instead.
4257 * tasking.c (build_rccase_set_error), ch-tree.h: Removed.
4259 * expr.c (build_generalized_call): If func is a signal type,
4260 call build_signal_descriptor.
4262 * parse.y (arrayindex): Renamed to index_mode, to match Z.200.
4263 * parse.y (ioindexmode): Removed; use index_mode instead.
4264 * expr.c (build_generalized_call): If args is a RANGE_EXPR,
4265 we have either a slice or a range mode, depending on func.
4266 * parse.y (index_mode): If we got an 'expr', only allow a name,
4268 * parse.y (call): A slice with both end points can be a range
4269 mode, so defer handling to build_generalized_call (or index_mode).
4271 * typeck.c (build_chill_slice_with_length): Fix type-checking.
4272 * typeck.c (chill_novelty): Undo (part of) change of April 28:
4273 The novelty of a range mode is the novlety of the parent.
4274 * typeck.c (chill_root_mode): Don't return integer_type_node
4275 if argument has non-nil novelty.
4277 * decl.c (global_bindings_p): Return -1 as true, for the sake
4278 of variable_size (in ../stor-layout.c).
4280 Fri Apr 29 13:42:43 1994 Per Bothner (bothner@kalessin.cygnus.com)
4282 * parse.y: Remove TYPENAME and modename. These are now plain
4283 NAMEs. Modify parsing actions appropriately.
4284 * expr.c (build_generalized_call): Handle the case that
4285 TREE_CODE (func) == TYPE_DECL (as in a cast).
4286 * lex.l (name_type_signal): Never return TYPENAME.
4287 * parse.y (get_type_of): If pass 1, just return the argument.
4289 * decl.c (do_decl): If an initializer has the wrong type,
4290 replace it by NULL_TREE, to avoid subsequent errors.
4292 Thu Apr 28 15:21:56 1994 Wilfried Moser (moser@rtl.cygnus.com)

4336 * typeck.c (smash_dummy_type): Handle the special case of a
4337 NEWMODE of a range mode, as required by Z200, by creating a
4338 new parent mode with the new novelty (and casting the min
4339 and max of the range to teh new parent mode).
4340 * typeck.c (chill_novelty, chill_root_mode): Remove special
4341 kludges for of NEWMODE ranges.
4342 * expr.c (build_chill_lower_or_upper): New function, combining
4343 the "guts" of build_chill_lower and build_chill_upper.
4344 * expr.c (build_chill_lower_or_upper): Simplify; no longer
4345 need to kludge the novelties.
4347 * typeck.c (valid_array_index_p): A string index expression
4348 need not be Compatible with the index type; only similar.
4350 * decl.c (layout_chill_variants): If error seen, skip stuff
4351 (rather than aborting or crashing).
4352 * decl (push_modedef): If newdecl's type is an error mark,
4353 continue rather than aborting.
4355 Thu Apr 28 02:07:42 1994 Doug Evans (dje@cygnus.com)
4357 * Make-lang.in: Update of directory reorg from fsf.
4358 * config-lang.in: Ditto.

4362 * typeck.c (chill_similar): Check RECORD_TYPEs properly,
4363 * convert.c (convert): If all else fails, just call convert1.
4364 Thus we can now convert RECORD_TYPEs (assuming they are similar).
4366 * parse.y, lex.l: Remove BUFFERNAME (use location/expr instead).
4367 * parse.y: Re-do BUFFER handling (similar to previous EVENT change).
4368 * grant.c (raw_decode_mode): Re-do BUFFER mode handling.

4373 * tasking.c ch-tree.h (expand_send_buffer): Now has 3 parameters.
4374 * parse.y (modename): No longer match SIGNALNAME. Instead, add it
4375 to name and simple_name_string. This removes a reduce/reduce conflict.
4376 * Makefile.in (stamp-parse): Expect fewer conlicts.
4378 * lex.l (yywrap): Move check for circularly seizeing current
4379 grant-file from here ...
4380 * lex.l (handle_use_seizefile_directive): ... to here.
4381 This is to avoid calling stat on a not-yet written grantfile,
4382 now that we're using same_file (which calls stat).
4383 * grant.c (set_use_this_gf): Removed.
4384 * grant.c (set_default_grant_file): Set grant_file_name here,
4385 because we need it earlier (due to above lexer change).

4397 (raw_decode_mode): Generalized to use decode_constant
4398 instead of print_an_int.
4399 (decode_constant): Print directly, instead of calling print_an_int.
4400 * parse.y (event_list): Fix syntax.
4401 * parse.y (optqueuesize): Default is NULL_TREE, not zero.
4402 * tasking.c (check_queue_size): New function, for error checking.
4403 * ch-tree.h: Add declaration for check_queue_size.
4404 * satisfy.c (satisfy case RECORD_TYPE): Satisfy constant fields

4421 make it compile. FIXME!
4422 * grant.c (raw_decode_mode): Use new max_queue_size function.
4423 Move EVENT support from LANG_TYPE to RECORD_TYPE.
4424 * ch-tree.h (process_event_decls): Removed.
4426 Tue Apr 19 11:44:01 1994 Bill Cox (bill@rtl.cygnus.com)

4431 Mon Apr 18 10:17:55 1994 Bill Cox (bill@cygnus.com)
4433 * Makefile.in (check): Simplified regression.sh call.
4434 * regression.sh: Change command-line parsing. Default
4435 srcdir to the script's path. Calculate objdir
4436 internally - don't pass it in.

4460 * lex.l (chill_same_grant_file): Rename to same_file. Change to
4461 take two files names rather than two DECLs. Also check that the
4462 filesystems (st_dev) are equal. Finally, make static.
4463 * lex.l (handle_use_seizefile_directive): Check for duplicate
4464 USE_SEIZE_FILE directives using same_file.

4481 * actions.c (chill_expand_assignment): Check for compatibility
4482 _after_ "expanding out" a binary operation. This fixes
4483 the case "STRING //:= CHAR".
4485 * lex.l (equal_number): Convert symbol to integer_type_node, to
4486 force the value to be INT-derived (and avoid novelty conflicts).
4488 Mon Apr 4 22:06:31 1994 Per Bothner (bothner@cygnus.com)
4490 * ch-tree.h (CH_FUNCTION_SETS_RESULT): New flag.

4504 or assign to DECL_RESULT as appropriate.
4505 * decl.c, ch-tree.h (current_function_returns_value,

4538 * tasking.c (make_process_struct): Change error message in case of
4539 a process argument has other attribute then IN or LOC.
4540 * tasking.c (build_start_process): Add check that the optset is
4541 referable in case it is specified (this makes
4542 noncompile/start_.ch working).

4588 Clean up error message for OUT//INOUT not location to use only 1 line.
4589 Add error message for OUT/INOUT if type is READonly.
4590 * typeck.c (build_chill_modify_expr): Simplify.
4592 Sun Mar 27 19:30:25 1994 Bill Cox (bill@rtl.cygnus.com)
4594 * Makefile.in: Clean up generally. Assure that

4613 file for optimized and unoptimized test results. Add the
4614 compiler's host and target triples to the report header.

4626 Wed Mar 23 13:34:18 1994 Bill Cox (bill@rtl.cygnus.com)
4628 * expr.c (build_generalized_call): Revert previous change.
4629 To do this correctly, we need a new parsing mechanism, and

4634 * expr.c (build_generalized_call): Be sure we're inside the

4651 * configure: Generate better .gdbinit files.
4653 Tue Mar 22 11:59:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
4655 * actions.c (check_range): Don't emit dynamic checks
4656 if not current_function_decl.
4658 * parse.y (arrayindex): Allow expr (error is emitted
4659 at semantic level if not the NAME of a type).
4660 * typeck.c (build_chill_cast): Re-enable some casts.
4661 * satisfy.c (safe_satisfy_decl): Remove redundant CONST check.

4678 string assignment case.
4679 * expr.c (chill_expand_expr): Now that we're using build_chill_function_call,

4681 type explicitly. Do that.
4682 * satisfy.c (safe_satisfy_decl): Correct range-checking code.
4684 Mon Mar 21 16:25:07 1994 Bill Cox (bill@rtl.cygnus.com)

4692 Mon Mar 21 13:29:23 1994 Per Bothner (bothner@kalessin.cygnus.com)
4694 * typeck.c (layout_chill_range_type): Instead of tree_int_cst_lt
4695 use compare_int_csts (which is more robust when signedness differs).

4698 * ch-tree.def (SET_IN_EXPR): New.
4699 * expr.c (chill_expand_expr): Code to expand SET_IN_EXPR,
4700 moved from expand_expr in ../expr.c. Also add some extra
4701 conversions (because we're now using build_chill_function-call).
4702 * actions.c, decl.c, expr.c, grant.c, parse.y, typeck.c:
4703 Use SET_IN_EXPR in place of IN_EXPR.
4705 * expr.c (build_compare_discrete_expr), ch-tree.h: New function,
4706 with code moved from build_compare_expr.
4707 * expr.c (build_compare_expr): Re-enable compatibility test.

4723 Generate a compile-time message if possible.
4724 (build_compare_expr): Comment out compatibility test - should

4731 list for __setbitpowerset,
4733 * typeck.c (chill_compatible_classes): Allow the M-reference
4734 to be compatible with the N-value class, with suitable M and N.
4735 * typeck.c (build_chill_slice): Don't smash a void TREE_TYPE.
4736 (We don't need to, and it causes confusion.)
4738 * expr.c (build_compare_expr): Fix thinko. Add save_exprs.
4740 * expr.c (build_compare_expr): Fix a transcription bug
4741 (for converting NULL INSTANCEs). Also #include convert.h.

4744 Works even if their types have different TREE_UNSIGNED.
4745 * expr.c (finish_chill_binary_op): Moved code dealing with
4746 the comparison operators from here ...
4747 * expr.c (build_compare_expr): ... to new function here.
4748 Also, for discrete types, tries to Do The Right Thing, even for
4749 differing values of TYPE_PRECISION and TREE_UNSIGNED.
4751 * ch-tree.h: Declare new functions.
4752 * typeck.c (valid_array_index_p): Various cleanups,
4753 including using new build_parse_expr.
4754 * parse.y: Use new build_compare_expr.
4756 * inout.c (build_chill_writetext): Handle REFERENCE_TYPE args.

4770 to get runtime index checking.
4771 * expr.c (build_chill_pred_or_succ): Fix cond tree
4772 to have consistent operand types.
4773 * typeck.c (valid_array_index_p): Change interface to pass
4774 validity conditions back on caller's TREE_LIST. We
4775 cannot link the conditions to anything which a
4776 layout_type routine will expand, since that will occur
4777 before the exception handler is set up.
4778 Change calls to valid_array_index_p also.
4780 Fri Mar 18 14:40:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
4782 * actions.c, except.c, loop.c, tasking.c: Call

4786 * loop.c (top_loop_end_check): Coerce library function arg.
4787 * convert.c, expr.c: Re-write to avoid calls to C-specific
4788 function build_unary_op (e.g. by calling build1 directly).
4790 * typeck.c (chill_equivalent): Change to force failure
4791 for non-matching integral types (even if not ranges).
4793 * typeck.c, ch-tree.h (build_chill_slice): Make non-static.
4794 * expr.c (varying_to_slice): Call build_chill_slice (and not
4795 build_chill_slice_with_length, which does bunches of range
4796 checking and does not allow the length to be zero).
4797 * convert.c (convert): Fix off-by-one error.
4798 * actions.c (chill_expand_array_assignment): Minor cleaning up.
4800 Fri Mar 18 00:12:48 1994 Per Bothner (bothner@deneb.cygnus.com)
4802 * decl.c (init_decl_processing): __lepowerset and __ltpowerset
4803 take *two* pointer parameters, not one.
4804 * satisfy.c (satisfy): Only call the appropriate layout routine
4805 if TYPE_SIZE is 0 (i.e. type hasn't already been laid out).
4806 * typeck.c (build_chill_slice_with_length): Fix Bill's previous fix.
4808 Thu Mar 17 17:29:43 1994 Bill Cox (bill@rtl.cygnus.com)
4810 * expr.c (build_chill_function_call): Give function call the correct
4812 * typeck.c (build_chill_slice_with_length): Restore dynamic range

4817 * typeck.c (build_chill_slice), expr.c (chill_expand_expr
4818 [case CONCAT_EXPR]): Remove kludge setting slice size upper bound
4819 in TYPE_LANG_SPECIFIC, and restore kludge setting it in MAX_VALUE.
4820 * typeck.c (build_chill_slice): Use TYPE_MAX_VALUE of
4821 array_type if needed for size upper bound of slice_type.
4822 * expr.c (build_concat_expr): Improve calculation of size upper bound.
4824 * typeck.c (valid_array_index_p): Check compatibility using
4826 * typeck.c (build_chill_slice_with_length); For now revert
4827 calling valid_array_index_p on length. (It makes it harder
4828 to realize when the slice is constant length.)
4829 * expr.c (build_chill_indirect_expr): Minor tweak. (This
4830 seems to work around a weird C compiler bug. ??)
4832 * expr.c (build_chill_function_call): Cleanup so it doesn't
4833 call build_function_call (in c-typeck.c).
4834 * typeck.c, expr.c: Use build_chill_function_call instead of
4835 build_function_call (in c-typeck.c).
4837 * parse.y (discrete_mode): Move some of the rules from
4838 non_array_mode into new non-terminal.
4839 (arrayindex): Use discrete_mode (with NAME and TYPENAME) to
4840 avoid some misparses.

4843 * decl.c (comptypes): Remove unused prototype.
4844 * decl.c (build_chill_function_type): Handle NULL return_type
4845 correctly (convert to void_type_node).

4852 * convert.c (convert): Correct calculation of padding length.
4853 * decl.c (grok_chill_fixedfields): Move ignore_exprs test to

4869 * expr.c (chill_expand_expr): Call build_chill_array_ref to get
4871 (build_hill_lower, build_chill_upper): Return value now inherits
4872 the novelty of the input parameter.
4873 (varying_to_slice): Use CH_NOVELTY macro rather than calling
4874 chill_novelty directly.
4875 * grant.c (newstring): Make len unsigned and cast xmalloc parameter
4877 (print_integer_type): Pass string value as APPEND's second parameter.
4878 (decode_decl): Pass a boolean expression as print_proc_tail's

4890 array index is checked.
4891 (build_chill_slice): Restore old functionality where varying_to_slice
4892 is called to handle slices of varying arrays, rather than handling
4894 (build_chill_slice_with_range, build_chill_slice_with_length):
4895 Check range limits for TREE_CONST before calling tree_int_cst_lt.
4896 Delete now-obsolete checks of constant indices.
4898 Mon Mar 14 17:26:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4900 * parse.y (modeless_expr): New rule to allow ([...]) and (if...)
4901 to count as untyped_exprs. (This is not really permitted by the
4902 Blue Book, but has been requested by customers.)
4904 Thu Mar 10 10:11:02 1994 Bill Cox (bill@rtl.cygnus.com)
4906 * chill.texi: Document new command-line options.

4911 * lex.l: Eat more whitespace.
4913 Thu Mar 10 09:41:37 1994 Bill Cox (bill@rtl.cygnus.com)
4915 * Makefile.in: Have rules to make parse.h, y.tab.c and other
4916 derived files. This allows the gcc/configure list of CHILL
4917 files machinery to work.
4918 * ch-tree.h (permanent_allocation): Add a parameter flag.
4919 * decl.c (finish_chill_function, finish_decl): Provide the
4920 new permanent_allocation flag.
4921 (poplevel): Return early, avoid a seg fault.
4922 * lex.l (NORMAL): Replace this whole state with the predefined
4923 INITIAL state. Force compilation state to global level after
4924 compiler directive error - prevents endless loop on error.
4925 (handle_use_seizefile_directive): Rewrite for readability.
4926 (chill_same_grant_file): Reindent.
4927 Generally handle whitespace differently.
4928 * regression.prpt: Print ten PR numbers per line. The report's

4933 * decl.c (do_decl): Suppress the string-assignment-condition
4934 error - it was too often seen.
4935 * expr.c (expand_chill_expr): In CONCAT_EXPR, when argument has a
4936 runtime-changing length (as in a slice), get the parent array's
4937 allocation size from its type tree.
4938 * typeck.c (build_chill_slice): Support VARYING arrays. Pass
4939 parent array's static allocation size along in the slice type.

4949 * lex.l (name_type_signal): Add debug output.
4950 * parse.y (call): Allow EVENTNAME and BUFFERNAME parameters
4951 to a call, so that SIZE () works on them.
4952 * tasking.c (make_process_struct): Force ignore_exprs non-zero
4953 when processing a SEIZEd PROCESS declaration. This prevents
4954 grox-fixed_fields from returning a NULL, and indirectly protects
4955 the chill_integer_type_node tree from corruption.

4966 register. Fixes the execute/inout.ch bug.
4967 * typeck.c (layout_chill_range_type): Restrict it
4968 from complaining about an empty string type's
4971 Mon Mar 7 09:06:39 1994 Bill Cox (bill@rtl.cygnus.com)

5006 * parse.y (optheader): Remove - it's obsolete, as is the
5007 HEADEREL token definition.
5009 Fri Mar 4 09:41:18 1994 Bill Cox (bill@rtl.cygnus.com)
5011 * addtest: Fix suffix removal when suffix is .c186.

5106 name for correctness.
5108 Wed Feb 23 15:07:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
5110 New cleaner solution to the following problem:
5111 Chill allows an action to be followed by an ON-handler.
5112 But we don't know if an action has a handler until we've parsed
5113 its end, yet we want to generate extra code to set up an
5114 exception handling contour only if needed. The old solution
5115 would generate code for the action into an rtl sequence, and then
5116 splice in the exception-setup code if we later found we needed it.
5117 This has a few problems (for example it confuses the management
5118 of stack temporaries), and is ugly. Now that the compiler is 2-pass
5119 we have a cleaner solution: In pass 1, we remember which actions
5120 were followed by ON-handlers. In pass 2, we use this information
5121 to generate appropriate code before an action.
5122 * except.c (push_handler, pop_handler): In pass 1, set up data
5123 structures (global_handler_list) to remember if an action has an
5124 ON-handler. In pass 2, digest this information, and setup
5126 * except.c, actions.h (pop_handler): Take an extra int arg.
5127 * except.c (emit_setup_handler): New function, with code (moved
5128 from chill_start_on) to emit code before an action that has a handler.
5129 * except.c (except_init_pass_2): New function.

5131 * parse.y (POP_UNUSED_ON_CONTEXT): Don't call pop_sequence.
5132 * parse.y: Invoke POP_UNUSED_ON_CONTEXT and POP_USED_ON_CONTEXT
5133 in pass 1 as well as pass 2.
5134 * parse.y (BEGIN ... END): Re-arrange logic to avoid block_stack
5135 (local to ../stmt.c) getting out of sync.
5136 * actions.c (push_action): Don't need to emit a NOP,
5137 now that we're no longer moving sequences around.
5138 * actions.c (push_action): Call push_handler even in pass one.
5140 Wed Feb 23 11:06:14 1994 Bill Cox (bill@rtl.cygnus.com)

5242 if TREE_TYPE has not been laid out.
5243 * typeck.c (build_chill_array_type): Update accordingly.
5244 * typeck.c (build_chill_slice): Replace calls to build_array_type

5247 * convert.c (convert): The same.
5249 * grant.c (decode_constant): Clean up. Remove remnants of switch

5802 'struct ch_class class = chill_expr_class (expr);' to
5803 'struct ch_class class; class = chill_expr_class (expr);'
5804 to work around a bug in /usr/ucb/cc on SunOS4.
5806 Mon Jan 10 18:29:36 1994 Bill Cox (bill@rtl.cygnus.com)
5808 * ch-actions.c (chill_convert_for_assignment): Avoid seg fault.
5809 * ch-expr.c (expand_packed_set): Add new parameter to pass
5810 set's minimum ordinal value. Fix loop invariant problem.
5811 (fold_set_expr): Change to add new parameter to
5812 expand_packed_set call.
5813 * ch-grant.c: Move extern declaration to ch-tree.h.
5814 * ch-lex.l (convert_bitstring): Also output the bitstring

5827 Convert result to correct class.
5828 * ch-expr.c (build_chill_repetition_op): Preserve CH_DERIVED_FLAG.
5829 Also, fix some bugs for bitstrings (with ranges).
5831 (Patches from Tiemann.)
5832 * ch-convert.c (convert1): New function to force TREE_TYPE.
5833 (convert): Use convert1 where appropriate.
5834 * ch-typeck.c: Formatting change.
5835 * ch-parse.y (build_chill_constructor): Fix thinko.
5837 * ch-expr.c (varying_to_slice): If array is not referable,
5838 call save_expr on it, rather than stabilize_reference.
5839 * ch-satisfy.c (safe_satify_decl, for CONST_DECL):
5840 Don't force value to value class if mode is not explicitly
5841 specified. Also, make sure convert etc is only done once.
5843 Sat Jan 8 16:37:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
5845 * ch-decl.c (build_chill_function_type): Don't call
5846 build_function_type, because it does hash canonicalization,
5847 which once in a while looses badly.
5848 * tree.c (build_function_type): Remove no-longer-needed test
5849 for doing_chill_thang.
5851 * ch-tree.h (CH_DERIVED_FLAG): New flag.

5865 convert_float, convert_number): Set CH_DERIVED_FLAG for literals.
5866 * ch-expr.c (finish_chill_binary_op): Use convert_to_class.
5867 * ch-satisfy.c (safe_satisfy_decl): For CONST_DECL, make sure
5868 DECL_INITIAL gets set to result of convert.
5869 Also, clear CH_DERIVED_FLAG for SYN value.
5870 * expr.c (store_constructor): If a [power]set is exactly one
5871 word long, use single-word move.
5873 Sat Jan 8 08:38:29 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5875 * c-typeck.c (chill_initializer_constant_valid_p): Fix typo.
5877 Wed Jan 5 05:18:46 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5879 * ch-typeck.c (build_chill_slice_with_length): Test that ARRAY is of
5880 ARRAY_TYPE before assuming so. Also, subtract 1 from LENGTH in
5881 computation of SLICE_END.
5883 * ch-typeck.c (chill_location): Treat CONSTRUCTORs like STRING_CSTs.
5885 * ch-expr.c (build_chill_indirect_ref): Handle MODE == NULL_TREE.
5887 * ch-expr.c (fold_set_expr): Handle OP1 == NULL_TREE (which happens
5888 for unary set operations).
5890 * ch-expr.c (build_chill_array_expr): Take new argument FORCE. All
5891 callers changed. All callers changed.
5893 * ch-convert.c (digest_structure_tuple): Handle SELECTED_VARIANT
5894 being NULL_TREE until we've started walking the list of values via
5895 the loop over VARIANTs.
5897 * ch-parse.y (build_chill_constructor): If we see an IDENTIFIER_NODE,
5898 treat it as an enum value (and hence constant). Also, only set
5899 TREE_STATIC if the constructor is indeed constant.
5900 * c-typeck.c (chill_initializer_constant_valid_p): If we see a
5901 VAR_DECL, test the TREE_CONSTANT field of the DECL_INITIAL, don't
5902 recurse on the DECL_INITIAL.
5904 Wed Jan 5 01:24:50 1994 Bill Cox (bill@cygnus.com)
5906 * Makefile.in: Add CHILL to LANGUAGES variable.
5907 * ch-actions.c (check_range): Call build_binary_op instead of
5908 fold, build to get the common types chosen.
5909 (cond_range_exception, cond_overflow_exception,
5910 cond_type_range_exception): Delete, obsolete.
5911 (chill_convert_for_assignment): Enable this, get particular
5912 about when to generate rangecheck code.
5913 * ch-expr.c (build_chill_function_call): Sketch in where to
5914 perform chill_convert_for_assignment on actual parameters.
5915 (build_chill_addr_expr): Correct compiler warning.
5916 * ch-loop.c (build_chill_iterator): Add runtime check for
5917 negative loop step expression.
5918 * ch-tree.h: Add prototype.
5919 * ch-typeck.c (chill_max_vary_array_ref): Correct misunderstanding.
5920 A varying array's length field counts the NUMBER of active array
5921 array entries, not the byte-length of them.
5923 Tue Jan 4 17:57:39 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5925 * ch-decl.c (do_decl): Call `suspend_momenary' if the
5926 converted constructor must live on the permanent_obstack.
5927 * ch-convert.c (convert): When building a new SET_TYPE
5928 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5929 * c-typeck.c (chill_initializer_constant_valid_p): Handle VAR_DECLs.
5931 * ch-typeck.c (chill_location): CONSTRUCTORS that are static
5933 * ch-satisfy.c (safe_satisfy_decl): Convert DECL_INITIAL of CONST_DECL
5934 on permanent_obstack if necessary.
5936 * ch-convert.c (digest_structure_tuple): When building a new SET_TYPE
5937 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5939 * ch-decl.c (do_decl): Fix handling of REFERENCE_TYPEs which
5940 the patch below helped to mess up.
5942 * ch-expr.c (build_chill_arrow_expr): Call `mark_addressable'.
5943 (build_chill_addr_expr): Take new argument ERRORMSG.
5944 All callers changed. Also, call `build_chill_addr_expr' where
5945 we used to call `build1 (ADDR_EXPR, ptr_type_node, ...)' since
5946 that now calls `mark_addressable' automagically.
5948 * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.
5949 This is needed because variables may appear in initialization
5950 statements, and their DECL_INITIALs are their values at
5951 initialization time.
5952 * ch-convert.c (digest_structure_tuple,digest_constructor): Changed
5953 to handle VAR_DECLs as initializers.
5955 * ch-convert.c (digest_structure_tuple): Copy elements of INITS so
5956 they aren't destroyed for later use.
5958 Tue Jan 4 15:25:30 1994 Bill Cox (bill@cygnus.com)
5960 * ch-expr.c (chill_expand_expr): Correct check-range lo_limit
5961 parameter for varying_array_ref calculations.
5962 (build_chill_indirect_ref): Prevent seg fault due to syntax error.
5963 * ch-typeck.c (build_chill_slice_with_range): Correct issuance
5964 of bogus error in votrics.
5965 (build_chill_slice_with_length): Change for debug tracability.
5967 Tue Jan 4 02:43:37 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5969 * ch-convert.c (digest_structure_tuple): Fix phasing problem in
5970 handling variant record initializers.
5971 (various places): Change `pop_init_level' calls to match
5972 `push_init_level' wrt implicit variable.
5974 * ch-typeck.c (build_chill_slice): Convert the dynamic max index to
5975 `integer_type_node' before using it in comparisons. FIXME: should
5976 this be done in `chill_max_vary_array_index' by default?
5978 Tue Jan 4 00:24:14 1994 Bill Cox (bill@cygnus.com)
5980 * ch-actions.c: Fix comments.
5981 * ch-parse.y: Define caseaction_flag.
5982 (caseaction): Create new caseaction_flag node at the start,
5983 then free it at the end. Check it before the ELSE code.
5984 (expanded_case_label): Check the flag here. If set in either
5985 place, generate a jump to the end of the case.
5986 * ch-typeck.c (build_chill_slice_with_length,
5987 build_chill_slice_with_range): Add lots of compile-time
5988 parameter range checking.
5990 Mon Jan 3 21:49:04 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5992 * ch-convert.c (digest_structure_tuple): Call `push_init_level' with
5993 implicit==0 everywhere, not 1.
5994 (digest_constructor): Ditto.
5996 * ch-actions.c (check_range): Permit limits to be NULL_TREE.
5997 Also, hack out some dead code.
5998 * ch-typeck.c (build_chill_slice): Check varying and non-varying
5999 slice constructs for range failures.
6000 (build_chill_slice_with_range): Reindented, but not changed.
6002 * ch-typeck.c (chill_max_vary_array_index): New function.
6003 * ch-expr.c (chill_expand_expr): Call it.
6005 * ch-decl.c (var_data_id, var_length_id): New variables.
6006 (init_decl_processing): Initialize them. All calls to
6007 get_identifier (VAR_LENGTH or VAR_DATA) are now replaced
6008 by references to these variables. This simplifies the code
6009 w/o obscuring anything.
6011 Mon Jan 3 21:24:44 1994 Bill Cox (bill@cygnus.com)
6013 * c-typeck.c: Fix comment.
6014 * ch-actions.c (chill_expand_assignment): Error assigning to
6015 READONLY location. (PR_3903) Pass filename, linenumber
6016 to setbitpowerset runtime routine.
6017 * ch-decl.c (init_decl_processing): Add filename, linenumber
6018 parameters to setbitpowerset prototype.
6019 * ch-expr.c (build_chill_function_call): Error when passing a
6020 READonly location as a LOC or INOUT parameter.
6021 * ch-parse.y (mode): Correct code marking type as readonly.
6023 Mon Jan 3 19:03:55 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6025 * ch-actions.c (chill_expand_assignment): Disable code that defeats
6026 building varying array references.
6027 * ch-expr.c (chill_expand_expr): Add rangecheck code to
6028 VARY_ARRAY_REF case.
6029 * ch-typeck.c (build_chill_array_ref): Don't call an `expand_'
6030 function (in this case, `validate_varying_array_ref') when we're
6031 doing a `build_' operation.
6033 * ch-typeck.c (validate_varying_array_ref): Simplify interface
6034 since INDEX parameter can never meaningfully be an INDEXLIST.
6035 * ch-actions.c (expand_varying_length_assignment): Caller changed.
6037 Mon Jan 3 07:29:45 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6039 * ch-typeck.c (build_chill_cast): Set TREE_CONSTANT on NOP_EXPRs.
6040 * ch-convert.c (digest_structure_tuple): Switch to permanent_obstack
6041 if we need to build a CONSTRUCTOR for a SET_TYPE initializer.
6042 (digest_structure_tuple): If TREE_VALUE (VALUE) == NULL_TREE, don't
6043 call CH_COMPATIBLE or try to convert it to TREE_TYPE (FIELD). This
6044 can happen when constructors are output incrementally.
6045 * c-typeck.c (initializer_constant_valid_p): Handle SET_TYPEs.
6046 * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
6049 Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6051 * ch-convert (digest_structure_tuple): Handle SET_TYPEs. Also, call
6052 `convert' so we can handle INSTANCE types (and other anomolies)
6055 * ch-convert.c (digest_structure_tuple): Fixed variant
6056 structure initialization. Also fixed a typo (TYPE_NAME
6057 was being used on a FIELD_DECL instead of DECL_NAME).
6058 * c-typeck.c (initializer_constant_valid_p): Pass missing
6059 ENDTYPE argument on recursive call.
6060 (set_init_field): New function, needed by ch-convert.c change above.
6062 * ch-decl.c (layout_chill_variants): Added a FIXME next to an
6063 almost certain typo.
6065 * ch-expr.c (build_chill_arrow_expr): Call `build1' and set
6066 TREE_CONSTANT for static references.
6067 * ch-except.c (chill_start_on): Change calls to
6068 `build_unary_op' (which is C-specific) to `build_chill_arrow_expr'
6069 which has CHILL semantics.
6070 * ch-convert.c (convert): Ditto (albeit in some disabled code).
6072 Sat Jan 1 21:26:43 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6074 * ch-satisfy.c (safe_satisfy_decl): Reorder conditional test of
6075 TREE_CODE of DECL in case it's altered by actions in the switch.
6077 * ch-satisfy.c (satisfy): Undo abort added earlier on 1 Jan. CVS log
6078 mentions where to find code that triggers this case.
6080 * ch-actions.c (adjust_parm_or_field): Handle CONSTRUCTORS here as
6083 * ch-convert.c (digest_structure_tuple): Push to permanent_obstack if
6084 we're dealing with a CONSTRUCTOR that is TREE_PERMANENT.
6085 (digest_constructor): Ditto.
6087 Sat Jan 1 10:29:19 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6089 * ch-parse.y (handleraction,resultaction,assignaction,call): Modified
6090 so that CONSTRUCTORS are properly handled before being used.
6092 * ch-convert.c (chill_start_init): New function. All callers to
6093 `start_init' changed to call this function instead.
6094 (digest_struct_tuple): Defend against initialization machinery
6095 mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
6096 IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
6097 needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
6098 can be refered to throughout the compilation unit. Also remove an
6099 extraneous call to `process_init_element' erroneously added to the
6100 variant record sub-loop.
6101 (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
6102 CONSTRUCTORS of SET_TYPE.
6103 * ch-parse.y (build_chill_constructor): Refix typo. Also set
6104 TREE_STATIC if at top level.
6106 * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
6107 TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
6108 should have been called.
6110 * ch-convert.c (digest_struct_tuple): Restore code which tracks
6111 field initializations so that the compiler can deduce what variant
6112 initializations to assume.
6114 * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
6115 when we push into a scope that has a DECL with a CONSTRUCTOR as its
6118 * ch-parse.y (build_chill_constructor): Change the name of the
6119 parameter to something more meaningful. Fix typo. Also, handle case
6120 where element is an untyped CONSTRUCTOR.
6122 * ch-except.c (finish_handler_array): Set TREE_CONSTANT on
6123 constant ADDR_EXPRs.
6124 (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT
6125 on JBUF_REF (instead of calling `build1' which does not).
6127 * ch-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
6129 * ch-typeck.c (chill_expand_tuple): Deleted.
6130 * ch-parse.y (primval rule): Don't call `chill_expand_tuple';
6131 instead, use initialization machinery for CONSTRUCTORS that
6133 * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
6134 that are created here.
6135 * ch-satisfy (satisfy): Abort in case we would have called
6136 chill_expand_tuple. FIXME: some other code is needed here,
6137 but I don't know what yet.
6139 * ch-parse.y (build_chill_constructor): New function to
6140 propagate TREE_CONSTANT bits to CONSTRUCTORS.
6141 (untyped_expr rule): Use it.
6142 (primval rule): Use it.
6144 * ch-decl.c (do_decl): Call `finish_init'.
6145 * ch-convert.c (convert): If we spontaneously create a CONSTRUCTOR in
6146 this function, make sure the initialization machinery is set up.
6148 * ch-convert.c (digest_structure_tuple, digest_constructor): Add
6151 Fri Dec 31 11:31:01 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6153 * ch-grant.c (chill_finish_module_code): Mark ADDR_EXPR built by hand
6154 as being TREE_CONSTANT. Otherwise it gets bounded by the initializer
6157 * ch-decl.c (do_decl): Change in CONSTRUCTOR handling due to...
6158 * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
6159 rewritten to work with GCC's initialization code. The basic change
6160 was to keep the initializers in sync with the initialization
6161 machinery that `process_init_element' imposes. Both of these
6162 functions now return `void'.
6163 * ch-convert.c (convert): Changed calls to `digest_...' functions.
6165 FIXME: the code handling UNION_TYPE (and variant records) has not
6168 Fri Dec 31 15:32:56 1993 Bill Cox (bill@rtl.cygnus.com)
6170 * ch-lex.l (convert_number): Output the converted number if
6172 * ch-parse.y (signaldef): Set ignore_exprs correctly for a
6175 Fri Dec 31 13:17:48 1993 Bill Cox (bill@cygnus.com)
6177 * ch-parse.y: Cleanup handling of RETURN actions, to distinguish
6178 a RETURN without a value (which cannot have an exception
6179 handler) from a RETURN with a value (which can). Eliminate
6180 some shift/reduce and reduce/reduce conflicts.
6182 Thu Dec 30 17:42:32 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6184 * ch-inout.c (build_chill_writetext): Deal with 2 cases where
6185 types returned from `type_for_size' are not expected. FIXME.
6186 * ch-decl.c (init_decl_processing): Mark `char_type_node' unsigned.
6187 This is required when range checking is enabled.
6189 Thu Dec 30 14:28:25 1993 Bill Cox (bill@rtl.cygnus.com)
6191 DELAY CASE works now.
6192 * ch-decl.c (init_decl_processing): Move rest of tasking-related
6193 initialization into tasking_init().
6194 * ch-parse.y (delaycaseaction): Pervasive additions/corrections.
6195 (optsetprio): New non-terminal.
6196 * ch-tasking.c (get_task_name): Delete, obsolete.

6200 (build_delay_case_start): Pass SET name and priority also.
6201 Generally update to correct functioning.
6202 (build_delay_case_label): Move between start and end fucntions,
6203 correct its functioning.
6204 (build_delay_case_end): Correct the code.
6205 (tasking_init): Lots of tasking-related code moved here from
6206 init_decl_processing.
6207 * ch-tree.h: Update, add prototypes.
6209 Wed Dec 29 10:13:10 1993 Bill Cox (bill@rtl.cygnus.com)
6211 * ch-expr.c (build_chill_indirect_ref): Revert change which
6212 failed full regression testing.
6213 * ch-lex.l (name_type_signal): Add debug output.
6214 * ch-parse.y (structured_variable): Add a debug variable.
6216 Wed Dec 29 02:05:51 1993 Bill Cox (bill@rtl.cygnus.com)
6218 * ch-decl.c (get_next_decl): Revert change which failed full
6221 Tue Dec 28 18:20:14 1993 Bill Cox (bill@rtl.cygnus.com)
6223 DELAY actions work now.
6224 * ch-decl.c: Correct spelling in comments.
6225 (get_next_decl): NULL out the decl's TREE_CHAIN before returning
6226 it, to prevent accidental access to the remembered_decls.
6227 (init_decl_processing): Add wait_event to runtime functions.
6228 * ch-expr.c (build_chill_indirect_ref): Prevent a syntax error from
6229 becoming a seg fault.
6230 * ch-grant.c: Correct a comment.
6231 * ch-loop.c: Delete/correct comments.
6232 * ch-parse.y (delaycaseaction): Add push/poplevel calls. Turn 'sorry'
6233 into rough draft of actual code.
6234 (delayaction): Don't make a new scope here, use get_unique_identifier
6236 (locdec): process event decls here, too.
6237 (mode): Add code to forbid READonly EVENT and BUFFER decls. Delete
6238 code which required EVENTs and BUFFERs to be declared at global scope.
6239 (simple_name_string): Add an EVENTNAME.
6240 * ch-satisfy.c (safe_satisfy_decl): Prevent a syntax error from
6241 becoming a seg fault.
6242 * ch-tasking.c (tasking_setup): Add the event queue's max. length
6243 as the 'entry_point' parameter in the list.
6244 (build_receive_case_start, build_receive_case_label): Defer
6245 calling runtime routine until we know whether we have a signal
6246 or a buffer to wait for.
6247 (build_delay_case_start, build_delay_case_end,
6248 build_delay_case_label, build_delay_action,
6249 process_event_decls): Added functions.
6250 * ch-typeck.c (chill_similar): Allow all integers of differing
6251 precisions to be similar.
6253 Thu Dec 23 18:00:40 1993 Bill Cox (bill@rtl.cygnus.com)
6255 * gcc.c (CHILL SPECS): Delete references to -M -MM -MD -MMD
6256 options. Delete C-specific defines. Disable piping from
6257 pre-processor to cc1chill (even if -pipe is specified), since cc1chill
6258 rewinds its input for its second pass. Piping still works
6259 from cc1chill to as.
6261 Thu Dec 23 12:31:55 1993 Bill Cox (bill@rtl.cygnus.com)

6347 when a module has both GRANTs and SEIZE ALL.
6349 * ch-expr.c (build_chill_arrow_expr): No longer re-write

7101 error message in pass 1.
7102 (sendaction): Add comments.

7110 parameter to know whether to include an init expression.

7180 * ch-convert.c: Move semicolon to separate line - easier to see.
7181 * ch-decl.c (do_decl): Handle untyped_expr initializers by
7182 simply using the variable's declared type - no compatibility
7183 check can be made if the expression has no type.

7186 (fold_set_expr): Fix two other endless loops by passing
7187 correct parameters to unpack_set_constructor.

7321 * ch-loop.c (build_temporary_variable, begin_for_range,
7322 init_loop_counter): Add parameter to decl_temp1 call.
7323 * ch-parse.y (quasi_signaldef): Clear quasi_signal flag here,

7378 * ch-typeck.c (chill_location): New function.
7379 Based on lvalue_p, but also handle Chill-specific VARY_ARRAY_REF.
7380 * ch-typeck.c, ch-tree.h (CH_LOCATION_P), ch-convert.c: Use
7381 chill_location instead of lvalue_p.
7384 Fri Oct 1 11:28:42 1993 Bill Cox (bill@cygnus.com)

7400 ch-convert.c (convert): Use it.
7401 * ch-typeck.c (build_chill_slice): Take length rather than upper
7402 bound. This makes it easier to recognize that A(X UP LENGTH)
7403 really has fixed length. Also, if the argument is string,
7404 mark the slice as a string too. Also, handle varying strings.
7406 * ch-typeck.c (conflate_singleton_strings): New global.
7407 * ch-typeck.c (chill_similar): If conflate_singleton_strings is
7408 set (as it currently is), allow CHARS(1)/BOOLS(1) to be similar
7409 to CHAR/BOOL, as required by the 1984 version of Z.200.
7410 * ch-convert.c (convert_to_char): Convert CHARS(1) to CHAR.
7411 * ch-convert.c ( build_array_type_for_scalar): If input is string,
7413 * ch-convert (maybe_turn_scalar_into_arra), ch-tree.h: Removed.
7414 * ch-convert.c (convert): Convert CHAR to CHARS(1).
7416 This fixes 'X // := Y' and is also a general simplification.
7417 * ch-actions.c (chill_expand_assignment): Convert 'LHS OP := RHS'
7418 to 'LHS := LHS OP RHS' (using stabilize_reference on LHS).
7419 Also, call save_expr on RHS if a multiple assignment.
7420 * ch-parse.y (assignaction): Therefore, no longer need to call
7421 stabilize_reference on RHS.
7422 * ch-typeck.c (build_chill_modify_expr), ch-tree.h: Remove
7423 modifycode parameter. Make it the caller's responsibility to
7424 handle <assigning operator>.

7426 ch-loop.c: Fix calls to build_chill_modify_expr accordingly.
7428 Wed Sep 29 18:02:55 1993 Per Bothner (bothner@kalessin.cygnus.com)

7435 * ch-tree.c (build_string_type): Pass string_index_type_dummy as
7436 the parent type of the index range.
7437 * ch-typeck.c (layout_chill_range_type): Recognize and handle
7438 string_index_type_dummy - specifically allow an empty range.

7442 * ch-convert.c (convert_to_reference): Check for loc-identity
7443 mismatches correctly (and remove one of those chill_compatible
7445 * ch-decl.c (decl_tasking_code_var): New function, called from
7446 push_extern_process and push_extern_signal.
7447 * ch-parse.y (end_function): Delete parameter. Check current_function_decl
7448 whether it's actually a process, and whether it has parameters.
7449 Make Michael's change simplifying the pass 2 test, preventing a seg
7451 (procedure, process): Change calls to end_function, remove
7452 code saving value from build_process_header. Delete redundant chill_
7453 phrases from some function calls.
7454 * ch-tasking.c: Remove some redundant _chill phrases from function
7456 * ch-tree.h: Remove some redundant _chill phrases from function
7457 names. Add the CH_VARYING_ARRAY_TYPE macro, call it from
7458 all relevant places.
7459 * ch-typeck.c: Use the new macro. Cast TREE_CODEs to chill_tree_code.
7461 Wed Sep 29 13:07:43 1993 Per Bothner (bothner@kalessin.cygnus.com)

7465 with a recursive convert call.
7466 * ch-decl.c (do_decl): Add missing compatibility-checking
7467 of initializer (don't depend on convert).

7471 * ch-tree.h (CH_LOCATION_P): New macro.
7472 * ch-typeck.c (layout_chill_range_type): Fix call to
7473 type_for_size, when figuring out a defaulted parent type.
7474 * ch-expr.c (build_chill_lower, build_chill_sizeof): Check
7475 for TREE_CODE_CLASS != 't' rather than == 'd'.
7476 * ch-expr.c (build_chill_function_call): Use CH_LOCATION_P
7477 to check for location, rather than TYPE_CODE_CLASS == 'd'.
7479 * ch-tree.c (build_string_type): Make 2-pass safe. Also,
7480 change parameter to be length, not index type.
7481 * ch-parse.y (mode2), ch-expr.c (build_concat_expr), ch-lex.l
7482 (build_chill_string): Modify callers of build_string_type accordingly.
7483 * ch-lex.l (check_newline): Don't look for # directive inside a
7485 * ch-grant.c (grant_array_type): Make more robust for char-
7486 and bit-strings (allow non-constant sizes). Change parameters
7487 and return types. (raw_decode_mode): Use grant_array_type
7488 for bitstrings. (otherwise): Fix grant_array_type callers.
7490 Mon Sep 27 16:57:57 1993 Per Bothner (bothner@kalessin.cygnus.com)
7492 Remove changes of Sep 15.

7494 * ch-typeck.c (chill_similar): Don't allow a singleton
7495 powerset to be similar to its domain.
7496 * ch-convert.c (convert_to_boolean): Don't convert a singleton
7497 SET_TYPE constructor to a Boolean.
7499 * ch-actions.c (chill_expand_assignment): Handle IN_EXPR on
7500 LHS of assignment, which is what we're current (temporarily?) using.
7502 Mon Sep 27 06:01:57 1993 Bill Cox (bill@rtl.cygnus.com)
7504 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
7505 ch-grant.c, ch-inout.c, ch-parse.y, ch-satisfy.c,
7506 ch-tasking.c, ch-tree.c, ch-tree.h, ch-typeck.c:
7507 -Wall cleanup. Add prototypes where missing.
7508 Delete unused variables. Cast uses of tree_codes
7509 to chill_tree_code, which they are.
7511 Sun Sep 26 13:09:57 1993 Bill Cox (bill@rtl.cygnus.com)
7513 * ch-decl.c (do_decl): Save initializer in pass zero
7515 * ch-lex.l: Fix comments, indentation.
7516 * ch-parse.y: Standardize error messages to use
7517 uppercase for CHILL keywords rather than quoting them.
7518 Suggestion from docs department.
7519 * ch-tasking.c: Pervasive changes to get processes to
7521 * ch-tree.h: Delete prototypes for functions whic
7522 I made static inside ch-tasking.c.
7524 Sun Sep 26 02:40:02 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7526 * ch-lex.l (yywrap): Call `check_newline' in case the file
7527 started with a line directive.
7529 Sat Sep 25 13:54:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
7531 * ch-decl.c: Expand pre-amble comment.
7532 * ch-decl.c (struct scope, push_module): Use new field
7533 tail_chain_module to build child-module list in order.
7534 (Just to make compiler debugging a little less confusing.)
7536 * ch-decl.c (struct scope): New field weak_decls.
7537 * ch-decl.c (find_implied_types): New interface. Now pre-pend
7538 new enum types to a given input list. This makes it easier to
7539 avoid duplicates, which should at least be more efficient.
7540 Also, handle FUNCTION_DECL.
7541 * ch-decl.c (bind_saved_names): Removed. Distribute its
7542 functionality over new functions (push_scope_decls, pop_scope_decls,
7543 build_implied_names, bind_sub_modules). The goal (which seems to
7544 have been more-or-less attained) was to fix weak name handling.
7545 * ch-decl.c (poplevel): Use new function pop_scope_decls.
7547 * ch-tasking.c (build_signal_struct, build_tasking_message_type):
7548 Use build_decl directly, rather than grok_chill_fixedfields
7549 (which depends on ignore_exprs and has more overhead).
7550 * ch-tasking.c (build_signal_struct): Construct the type
7552 * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
7553 than build_array_ref (which does C-specific "optimizations").
7554 (Hence move my_build_array_ref up earlier in the file.)
7556 Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7558 * ch-tasking.c: Declare static variable `void_ftype_void'.
7559 (chill_tasking_init): Initialize `void_ftype_void' here.
7560 (build_tasking_struct): Use, don't declare `void_ftype_void'.
7561 (generate_tasking_code_variable): Call `do_decl', not
7562 `decl_temp1' to declare TASKING_CODE_NAME.
7563 (tasking_setup): Drop into 1-pass mode so that all
7564 tasking-related declarations are installed in the global
7565 scope. Use correct CHILL types for initializers (since
7566 ptr_type_node doesn't have the right meaning for CHILL).
7567 Also, call `do_decl' instead of `decl_temp1' for
7569 (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
7570 `chill_finish_compile' in sync between passes.
7572 * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
7573 declarations on pass zero. Keep obstacks in sync, and always
7574 call `finish_decl' for pass zero declarations.
7575 (push_chill_extern_function): Keep obstacks in sync, and always
7576 call `finish_decl' for pass zero declarations.
7577 (build_enumerator): Ditto.
7578 (grok_chill_variantdefs): Change PASS test to exclude only
7580 (finish_struct): Ditto.
7581 * ch-expr.c (build_chill_component_ref): Ditto.
7582 (build_chill_binary_op): Ditto.
7583 * ch-tree.c (build_powerset_type): Ditto.
7584 (build_bitstring_type): Ditto.
7585 * ch-typeck.c (build_chill_range_type): Ditto.
7586 (build_chill_struct_type): Ditto.
7588 * ch-decl.c (build_chill_exception_decl): Clarify reasons for
7589 extra pushing and popping of obstacks.
7591 * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
7592 on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
7594 * ch-grant.c (chill_finish_compile): Clear out both
7595 MODULE_INIT_LIST and TASKING_LIST if either contains stuff
7598 * ch-parse.y (rccase_label): Add NAME rules so that pass one
7599 works w/o knowing we're parsing a signal. Simplify SIGNALNAME
7600 rules since we only get SIGNALNAME tokens in pass two.
7601 (sendaction): Ditto.
7602 * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
7603 BUFFERNAME on pass two. The grammar now handles this.

7606 Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
7608 * ch-decl.c (lookup_remembered_names): Removed. It was being
7609 misused in ch-lex.l.
7610 * ch-lex.l (name_type_signal): Revert last change. Basically,
7611 we cannot use the C typedef/variable name trick in CHILL, due
7612 due to the language's 2-pass nature.
7613 * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
7615 * ch-tree.h (lookup_remembered_name): Comment out the prototype.
7617 Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)

7629 Replace NAME references with SIGNALNAME references.
7630 (startaction): Only check copy number if not ignoring actions.
7631 Always call build_chill_start_process.
7632 (optstartset): Don't lookup the instance name.
7633 * ch-tasking.c (generate_tasking_code_variable): Replace

7669 ALIAS_DECL the name in the most recent use_seize_file directive.
7670 (This requires that use_seize_file directives written to the
7671 grant file be written before the SEIZEs that need it.)
7672 Allow clashing declarations granted into the global scope
7673 (produce a warning), but remember the seizefile case from
7674 (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
7675 The a SEIZE will select the granted decl that matches its
7676 DECL_SEIZEFILE (in other words: grants from the most recent
7677 use_seize_file will be preferred).
7678 * ch-tree.h (DECL_SEIZEFILE), ch-tree.def: New macro.
7679 * ch-tree.h (global_value, IDENTIFIER_GLOBAL_VALUE): Renamed
7680 to outer_value, IDENTIFIER_OUTER_VALUE.

7686 Don't call grant_use_seizefile.
7687 * ch-lex.l (mark_use_seizefile_written): New function.
7688 * ch-grant.c (decode_decl): Write out use_seize_file directive,

10283 function, for external and seized function declarations.
10284 Make sure to use permanent obstack.
10285 * ch-parse.y (quasi_pdef, extprocedure): Use new function.
10287 * ch-grant.c (chill_finish_module_code): Since module
10288 function is no longer visible,, can't get it using
10289 lookup_name(). Use current_function_decl instead.
10291 * ch-decl.c (build_chill_function_type): Add void_type_node
10292 to end of parameter types list.
10294 * ch-grant.c (chill_start_module_code): Make sure module

10365 (start state 'ccitt'): Deleted, unused. Moved unused, but reserved,
10366 tokens to NORMAL state.
10367 (compiler_directive): Replaced by equal_number. Now the only
10368 recursive call to yylex happens in check_newline at the beginning
10371 Sat Apr 10 09:55:50 1993 Bill Cox (bill@rtl.cygnus.com)
10373 * ch-actions.c (build_chill_case_expr): Added from ch-parse.y.
10374 * ch-lex.l (ENTRY, PERVASIVE, ROW, STEP): Add token recognition to
10376 * ch-parse.y (case_expr): Move code into ch-actions.c. There will

10379 * ch-tree.h (build_chill_case_expr): Add prototype.
10380 * ch-typeck.c (build_chill_cast): Allow untyped_expr - just assign the
10381 type to the expr. Check for CASE_EXPR, call expand_case_expr.
10383 Sat Apr 10 01:10:51 1993 Per Bothner (bothner@rtl.cygnus.com)
10385 * ch-parse,y (in_pseudo_module): New variable. Try if we're
10386 in a seizefile, but not in a module nested in the seizefile.
10387 Use for backwards compatibility with old grantfiles.

10399 * ch-lex.l: Re-write to use start states, to avoid calling
10400 yylex() recursively.
10401 * ch-lex.l (compiler_directive); This is now obsolste. FIXME.
10402 * ch-lex.l: Call push_module and pop_module when reading a
10403 seizefile. This creates a pseudo-module.
10404 * ch-parse.y: Clean up handling of empty declarations and
10405 action statements; semicolons are now optional a number of
10407 * ch-parse.y: Remove some bogus tests for "statement
10408 out of sequence" (they're both legal and work).
10409 * varasm.c (mak_function_rtl): Remove kludge that may
10410 not be necessary (and loses anyway).
10412 Fri Apr 9 09:37:38 1993 Bill Cox (bill@rtl.cygnus.com)
10414 * ch-expr.c (chill_expand_array_assignment): Remove false error about

10431 which is the list (in order) of decls in the module.
10432 Don't reverse the getdecls() list; that is handled by caller.

10434 visible before writing it.

10436 from surrounding module.
10437 * ch-parse.y (pop_module): Restore those declarations.

10450 assignment, clean up.
10451 * ch-typeck.c: Add prototype for require_complete_type.

10461 * ch-decl.c (massage_param_node): New function.
10462 It handles the LOC/IN/OUT/INOUT parameter distinction,

10464 * ch-tree.h (massage_param_node): New prototype.
10465 * ch-decl.c (push_parms): Use new massage_param_node().
10466 * ch-parse.y (pmodearg): Use new massage_param_node().

10490 Mon Apr 5 19:56:56 1993 Bill Cox (bill@rtl.cygnus.com)
10492 * ch-actions.c, ch-decl.c: Use tree_int_cst_equal and integer_zerop

10512 Fri Apr 2 21:55:14 1993 Per Bothner (bothner@rtl.cygnus.com)
10514 Major re-write of New module/seize/grant stuff.
10515 Now, a grantfile is a spec module and contains all the
10516 top-level declarations of the granting module, not just
10517 those that are granted. It also contains explicit grant
10518 statments naming those declared names that are granted.
10519 It also has seize statements and use_seize_file directives
10520 to correctly handle transitive dependencies.
10522 * ch-parse.y: Change to allow multiple modules per source file.
10523 Allow spec modules (including quasi definitions) as well as
10525 Allow spec modules inside normal modules; these behave as if
10526 they were outermost. This violates the Blue Book, but is
10527 needed by the new grantfile mechanism. (A grant file is a
10528 spec module that gets included by the use_seize_file directive.)
10529 * ch-parse.y (struct module *current_module, push_module,
10530 pop_module): Support module nesting (for spec modules only).
10532 * ch-tree.h (struct module): New.
10533 * ch-grant.c (granted_decls): New list of declarations
10534 that have been granted into the outermode pseudo-module.
10535 * ch-grant.c (decode_mode): If the decl has a name,
10536 always write the name, not just if the decl has already
10537 been written. Since we write out all decls, we can assume
10538 it will be written later, and depend on the forward
10539 declaration kludges to catch it.
10540 * ch-grant.c (decode_decl): Don't write out _EXTERN.
10541 Instead write out standard (Blue Book) quasi-definitions.
10542 * ch-grant.c (push_granted): New function.
10543 * ch-grant.c (seize_implied_names): New function. Re-write
10544 how set element names are seized when a set type is seized.
10545 * ch-grant.c (chill_seize): Work by seraching the
10546 granted_decls list and copying the declaration.
10547 * ch-grant.c (chill_grant): Write all declarations
10548 declared in this module. Write GRANT statements for
10549 those granted. seize statements for decls seized from
10550 other modules. Write extra syntax to make a complete
10552 * ch-grant.c (grant_use_seizefile): Copy use_seize_file
10553 directives into grant file.
10554 * ch-lex.l (setup_seizefile_read): Call grant_use_seizefile.
10556 * ch-lex.l (struct input_state, current_input_state,
10557 push_input_file, pop_input_file): New (type, variable,
10558 function*2). Used to save and restore state on an input file.
10559 * ch-lex.l: Clean up to handle nested input seizefiles
10560 (needed by new grant/seize mechanism.
10561 * ch-lex.l (skip_to_end_of_directive): New function.
10562 * ch-lex.l (compiler_directive: USE_SEIZE_FILE): Make sure
10563 we skip to the end of the directive *before* we switch
10565 * ch-lex.l (setup_seizefile_read): Prevent reading the
10566 same seizefile twice (otherwise likely with new grant/seize).
10567 * ch-lex.l: Recognize SPEC. Misc cleanups.
10569 * ch-parse.y: Fixed foreward references of types.
10570 Removed the unknown_type_node crock.
10571 * ch-decl.c: Remove all uses of unknown_type_node.
10572 Check for TYPE_SIZE zero instead.
10573 * ch-decl.c (fixup_unknown_type): Make sure new mode
10574 gets copied into old mode. Merge their variant chains.
10575 * c-decl.c (lookup_name_current_level): Make non-static.
10576 * ch-decl.c (lookup_name_current_level): No longer needed.
10578 * ch-parse.y (call): Allow an implicitly defined function
10579 name following the CALL keyword.
10580 * ch-tree.h (struct lang_identifier): Add implicit_decl,
10581 and make sure order of fields matches c-tree.h.
10583 * ch-actions.c (lang_init, build_allocate_memory_call,
10584 build_allocate_globals_memory_call): Fix names (add initial '_')
10585 and prototypes of _allocate_[global_]memory (2nd param is ref).
10586 Use build_chill_function_call, not build_function_call,
10587 so the reference parameter gets handled.
10588 * ch-actions.c. (lang_init): Make sure boolean_{true,false}_node
10589 have boolean_type_node as their types.
10590 * ch-actions.c (build_chill_lower, build_chill_upper): Fix to
10591 work for arrays with BOOLEAN_TYPE ranges (and simplify some).
10593 * ch-except.c: Make sure an end_label is generated,
10594 and jump to it if there is no exception.
10596 * ch-convert.c (convert_to_reference): Strip off NOP_EXPR casts.
10597 * expr.c (expand_expr): Handle NOP_EXPR as Chill-style casts.
10598 (Need cleaning up and FSF installation!)
10599 * ch-parse.y: If taking the address of a cast, move the
10600 ADDR_EXPR inside the NOP_EXPR.
10602 * ch-typeck.c (my_build_array_ref): Simplified, more suitable
10603 versions of build_array_ref from c-decl.c. (E.g. don't barf
10604 if index type is char or bool.)
10605 * ch-typeck.c (build_chill_array_ref): Use my_build_array-ref.
10607 * ch-typech.c (build_chill_bin_type): New function.
10608 Support BIN(N) range type specification.
10609 * ch-parse.y (mode2), ch-lex.l: Recognize BIN(N).
10611 * ch-tree.h (CH_SIMILAR): Redefine in terms of chill_similar.

10613 that range types are similar to their parent types.
10615 * ch-tree.h: Declare flag_local_loop_counter.
10616 * ch-loop.c: Whether the loop variable is local to the loop
10617 in now controlled by flag_local_loop_counter, instead of
10618 #ifdef'd on CREATE_SCOPE.
10619 * ch-actions.c (lang_decode_option): Recognize flags
10620 "-f[no-]local-loop-counter".
10621 * toplev.c (lang_options): Add Chill flags -f[no-]local-loop-counter.
10623 * varasm.c (make_function_rtl): Due to problems with forward
10624 references, don't rename nested functions in Chill. (Kudge!)
10626 Sun Mar 28 10:12:45 1993 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10628 * ch-lex.l (push_back, readstring): Fix prototypes.
10630 Fri Mar 26 18:32:15 1993 Bill Cox (bill@rtl.cygnus.com)

10639 * ch-parse.y (get_type_of): Add function to deal with possible fwd
10640 declared type name. Call it from lotsa places. Add lotsa checks

10650 as-yet-undeclared types. Check for IDENTIFIER_NODE, lookup its
10651 DECL if there, pass TREE_TYPE of decl to build_pointer_type.
10652 (variantfields, varianthack): Clean up.
10653 (variantfield): Check for IDENTIFIER_NODE, lookup its DECL if
10654 there, pass TREE_TYPE of decl to grok_fixedfields.
10655 (labellist): Explicitly assign error_mark_node to signal error.
10656 * ch-typeck.c (chill_compatible): Report FALSE for bad parameters,

10689 array and its type get on the permanent obstack.
10690 * ch-grant.c (write_grant_file): Don't write the _INIT=name
10691 specifier: It isn't needed, and loses (because of funny
10692 characters in the chill_initializer_name).
10693 * ch-decl.c (push_synmode): Set TYPE_NAME(mode) = syndecl.
10694 * ch-lang.c (finish_chill_enum): Don't allocate a dummy
10695 TYPE_DECL for the enum. I don't think it is needed (?),

10734 vents seg fault when only WITH operand is invalid.
10735 * ch-parse.y (label_spec): Correct assignment within IF expression which
10736 was intended to be equality test. Remove unused variables.
10737 * ch-tree.h: Add prototype. Remove unused EXCP_CODE enumeration, and
10738 prototyping editorial comments.
10739 * ch-typeck.c: Disable generation of code to validate array index for

10894 * ch-loop.c: Make CREATE_SCOPE #define to enable creation of a new scope
10895 for each CHILL loop, as Z.200 requires. Add powerset and error flags
10896 to loop structure. Evaluate user's powerset expression into a temp,
10897 scan it destructively with __ffsetclrpowerset or __flsetclrpowerset
10898 for powerset loop. Only do loop-end assignments if NOT a powerset
10899 loop, which has much less overhead now.

11167 types such as bitsets.
11168 * ch-tree.c (build_bitstring_type): Set TYPE_MIN_VALUE

11174 Make integer_type_node etc have the same size as in cc1.
11175 New types chill_integer_type_node and chill_unsigned_type_node
11176 that correspond to the Chill source types INT and UINT.
11177 For now, these match the C 'short' types, but that should
11178 become a configuration option later,

11200 * ch-tree.def: add a new tree type - just for varying array
11201 references. We were using ARRAY_REF, but the underlying C
11202 code also generates that one.
11203 * ch-convert.c, ch-expr.c, ch-typeck.c: use the new tree type.
11205 Sun Feb 7 17:33:17 1993 Bill Cox (bill@rtl.cygnus.com)

11432 * dwarfout.c (output_type): Add hack that matches the one in the
11433 chill front end to distinquish between true string types and
11434 arrays of char, since it uses ARRAY_TYPE for both, rather than
11435 trying to use the existing support for STRING_TYPE.

11497 * chill.gperf, ch-hash.h: add Wilfried's tokens
11498 * ch-lex.l: fold in Wilfried's changes. Some tokens

11577 for the special varying field names.
11578 * ch-tree.h: define macros for varying field names.
11579 * ch-expr.c: use macros for varying struct names. Simplify
11580 chill_expand_array_assignment.

11609 Mon Jan 4 17:57:48 1993 Per Bothner (bothner@cygnus.com)
11611 * ch-grant.c, ch-parse.y: Remove all code for explicitly
11612 calling initializer functions. This is not needed, since we
11613 use the same mechanism used for C++ static constructors.
11614 * ch-grant.c (chill_start_module_code): Make sure the
11615 init_name starts with the magic string also used for C++
11616 initializers. Also, don't embed the file name in the name,
11617 just use the module name.
11618 * ch-grant.c (chill_finish_module_code): Now that the
11619 initializer name follows the standard 'collect' convention,
11620 don't need to call assembler_constructor_alias, but can
11621 use the standard assemble_constructor instead.
11622 * varasm.c (assemble_constructor_alias): Remove no-longer-
11624 * ch-parse.y: Move code that is common to the beginning of
11625 all functions to a new macro INIT_ACTION.
11626 Make sure INIT_ACTION is also done for callaction, fixing a bug.
11627 * ch-parse.y (INIT_ACTION): Do chill_start_module_code()
11628 before emit_line_note(), not after.
11630 Mon Jan 4 11:43:12 1993 Bill Cox (bill@cygnus.com)
11632 * ch-parse.y: restore requirement for :upper-bound in array decl.
11633 * ch-actions.c: enhance upper, lower, length functions for VARYING.
11635 Mon Jan 4 09:28:44 1993 Bill Cox (bill@cygnus.com)

11652 * ch-parse.y: define IGNORED_DIRECTIVE
11653 * ch-typeck.c: subtract array's lower domain value, even if
11654 index expression is constant.

11658 * ch-lex.l (convert_float): Fix misspelling in error message.
11660 Sat Jan 2 16:02:16 1993 Per Bothner (bothner@rtl.cygnus.com)
11662 * Makefile.in: Took out chill-runtime support.
11663 Chill run times are now in ../chillrt, not ./chillrt.p
11665 Sat Jan 2 15:04:13 1993 Bill Cox (bill@cygnus.com)
11667 * ch-hash.h, chill.gperf: cleanup. fewer keywords seen by ch-parse.y.
11669 Sat Jan 2 13:27:49 1993 Per Bothner (bothner@rtl.cygnus.com)
11671 * ch-lex.l (check_newline): Use the orginal versions (derived
11672 from the C code, not the simplified, special-case version).
11673 Also, fix that version of check_newline to not call yylex()
11675 * ch-lex.l (yy_input): Call check_newline to handle
11676 newlines and check for # directives.
11677 * ch-lex.l (syntax): Don't recognize #-directives; these
11678 are now handled by check_newline.
11679 * ch-actions.c (lang_init): Call the modified version of
11680 check_newline(). Do this at the *after* we've initialized
11681 standard types, so this can be done while lineno is still 0.
11683 Sat Jan 2 10:57:20 1993 Bill Cox (bill@cygnus.com)
11685 * ch-hash.h, chill.gperf: add remaining reserved words.
11687 Sat Jan 2 09:59:55 1993 Bill Cox (bill@cygnus.com)
11689 * ch-tree.h, ch-parse.y, ch-lex.l: add remaining reserved words,
11690 names for exceptions
11692 Fri Jan 1 12:30:31 1993 Fred Fish (fnf@cygnus.com)
11694 * ch-tree.h (JOINER): Define joiner character the same way
11696 * ch-grant.c (chill_start_module_code): Use JOINER character
11697 to implement name mangling for the initializer function name.
11698 Algorithm is designed to be simple, distinct from C++ mangled
11699 symbols, and easy to convert to demangled form.
11701 Thu Dec 31 10:30:51 1992 Bill Cox (bill@rtl.cygnus.com)
11703 * ch-expr.c: make array assignments work with indirect refs.
11704 * ch-actions.c: prepare for array parameter handling.
11705 * ch-loop.c, ch-parse.y, ch-tree.def, ch-typeck.c: clean up.
11707 Thu Dec 31 15:29:20 1992 Per Bothner (bothner@rtl.cygnus.com)
11709 * ch-lex.l (yy_input): Re-write to return more than one
11710 character at a time (execpt when reading seize-files).
11711 Don't increment lineno until we start reading the next line.
11712 This fixes some off-by-one errors in lineno.
11714 Wed Dec 30 16:15:23 1992 Per Bothner (bothner@rtl.cygnus.com)
11716 * ch-convert.c: Assume use of new common.c.
11717 * ch-convert.c (convert_to_reference, convert_from_reference):
11718 New routines, to handle loc-identity declared variables and
11719 LOC parameters (both of which are implemented as references).
11720 * ch-lang.c (convert_to_boolean, convert_to_char): Move to
11721 ch-convert.c, where they would seem to belong.
11722 * ch-convert.c (convert): New function, since we no longer
11723 link in c-convert.c.
11724 * ch-expr.c (chill_expand_assignment): Handle by calling
11725 convert() instead of chill_comptypes().
11726 Also handle the LHS being a reference.
11727 * ch-parse.y: Add a procedure call as an action.
11728 * ch-parse.y (locdec, optlocinit): Move handling of
11729 loc-identity declarations from optlocinit to locdec
11730 - and add working semantics for it.
11731 * ch-parse.y (seizestatement, visibilty_stmt): Simplify.
11732 * ch-parse.y (grantstatement etc): Don't bother making list.
11733 * ch-lex.l: #include <sys/types.h> before <sys/stat.h>.

11737 * ch-parse.y, ch-expr.c: add support for declaring & assigning
11739 * ch-typeck.c: allow VARYING structures in assign_type_to_expr.
11741 Tue Dec 29 15:28:48 1992 Bill Cox (bill@cygnus.com)
11743 * ch-actions.c: implement expressions of arrays of char,
11744 ( concatenation, relationals ), correct type of code parameters
11745 * ch-expr.c: correct type of code parameters
11747 Tue Dec 29 11:16:19 1992 Bill Cox (bill@cygnus.com)
11749 * ch-decl.c: cleanup.
11750 * ch-parse.y: put emit_line_note() calls in lotsa places,
11751 per Fred's request; be sure that statements get counted also.
11752 * ch-lex.l: standardize function headers.
11754 Tue Dec 29 10:41:56 1992 Fred Fish (fnf@cygnus.com)
11756 * ch-decl.c (start_chill_function): Always return 1, rather
11757 than a random value.
11758 * ch-lex.l (check_newline): Add a version for chill that
11759 just snarfs the right value for main_input_filename out of
11760 the first line of the input file, without disturbing the
11761 lexer state or requiring it's assistance.
11762 * ch-actions.c (lang_init): Call check_newline, like the
11763 other language frontends, to get main_input_filename set
11764 from first line of input file.
11766 Mon Dec 28 18:49:01 1992 Bill Cox (bill@cygnus.com)
11768 * ch-parse.y: clean up conflicts. The remaining one is
11771 Mon Dec 28 17:28:40 1992 Bill Cox (bill@cygnus.com)
11773 * ch-parse.y, ch-lex.l, ch-actions.c: add stubs for I/O,
11774 clean up some parser conflicts.
11776 Mon Dec 28 15:00:20 1992 Bill Cox (bill@cygnus.com)
11778 * ch-parse.y, ch-lex.l: add keywords and parsing for most of
11781 Sat Dec 26 20:48:23 1992 Fred Fish (fnf@cygnus.com)
11783 * chillrt/chillrt0.c: Oops, SVR4 doesn't need leading '_'
11784 on build_exceptions.
11786 Sat Dec 26 11:00:36 1992 Fred Fish (fnf@cygnus.com)
11788 * ch-grant.c (chill_finish_module_code): Call
11789 assemble_constructor_alias rather than assemble_constructor.
11790 * varasm.c (assemble_constructor_alias): New function,
11791 like assemble_constructor, but also handles the case where
11792 ASM_OUTPUT_CONSTRUCTOR is not defined and GNU ld is not
11793 being used. Emits a symbol table alias name with the correct
11794 prefix for collect to find and add to the __CTOR_LIST__.
11795 * chillrt/chillrt0.c: Build on previous hack that gets
11796 _build_exceptions into the __CTOR_LIST__, to make it work
11797 for both the non GNU-ld case and for the SVR4 case.
11799 Tue Dec 22 18:24:55 1992 Bill Cox (bill@cygnus.com)
11801 * ch-loop.c: clean up location enumeration - one more

11815 ch-loop.c: rough draft of location enumeration
11816 ch-lex.l, ch-expr.c, ch-decl.c: minor cleanup
11817 ch-actions.c: finish making pred() and succ() work.
11819 Mon Dec 21 10:04:35 1992 Bill Cox (bill@cygnus.com)
11821 * ch-actions.c: allow pred(char) and succ(char).
11823 Sun Dec 20 16:04:28 1992 Bill Cox (bill@cygnus.com)
11825 * ch-expr.c, ch-actions.c, ch-parse.y, ch-loop.c,
11826 c-expr.c: make DO WITH work.
11828 Sun Dec 20 12:22:53 1992 Bill Cox (bill@cygnus.com)
11830 * ch-loop.c, ch-actions.c, ch-typeck.c: powerset loops
11833 Sat Dec 19 14:20:23 1992 Per Bothner (bothner@cygnus.com)
11835 * c-typeck.c (process_init_constructor): Add warning if
11836 there is a duplicate default initializer element.
11837 * ch-typeck.c (chill_give_type_to_expr): New function,
11838 to handle coercion of an expression to context-given type,
11839 Takes care of untyped tuples, and case expressions.
11840 * ch-decl.c (do_decls), ch-typeck.c (chill_expand_return,
11841 chill_expand_result), ch-parse.y <assignaction>:
11842 Use chill_give_type_to_expr().
11843 * ch-typeck.c (chill_handle_case_label): New parameter list,
11844 to handle the (new) conventions for <case_label>, including
11845 default elements and ranges.
11846 * ch-parse.y <expanded_case_label>, ch-typeck.c
11847 (expand_case_expr): Use new version of chill_handle_case_label.
11848 * ch-decl.c (push_syndecls): Change parameters: Instead of
11849 TREE_LIST representing a compete <synonym definition statement>,
11850 just pass the parts of a single <synonym definition> as 3
11851 different parameters. Also, use chill_give_type_to_expr(),
11852 to handle untyped tuples in the RHS.
11853 * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct
11854 a tree - just call push_syndecls() on each <synonum_definition>
11856 * ch-parse.y (exprlist_get_single): Remove; no longer needed.
11857 * ch-parse.y: Handle <tuple> without mode name diferently from
11858 <tuple> with mode name. The latter is a <primval> that can be
11859 in most contexts, but if the <mode name> is missing, the <tuple>
11860 is only allowed in certain contexts. Use the new non-terminal
11861 <untyped_expr> to indicate those contexts where untyped tuples
11862 (and case expressions) are valid because the expression gets a
11863 type from its context (such as the RHS of an assignment).
11864 Use chill_give_type_to_expr in those contexts.
11866 Sat Dec 19 14:01:26 1992 Bill Cox (bill@cygnus.com)
11868 * ch-actions.c, ch-loop.c, Makefile.in: looping stuff.
11870 Sat Dec 19 10:16:20 1992 Bill Cox (bill@cygnus.com)

11877 * ch-actions.c (maybe_chill_comptypes): Delete unused
11879 (chill_comptypes): Add new parameter ERRSTR. All callers
11881 (build_chill_binary_op): Fix indentation to match GNU coding
11884 Fri Dec 18 08:18:13 1992 Bill Cox (bill@rtl.cygnus.com)
11886 * ch-parse.y, ch-expr.c, ch-actions.c, expr.c: major

11896 a default initializer element.
11897 * ch-parse.y: Implement default elements for tuples
11898 (as in '(else):' and '(*):' ).
11900 * ch-parse.y: Previous change to dis-ambiguate case-labels
11901 seems to have allowed getting rid of all of the expr_or_list hair.
11902 * ch-decl.c (do_decls): Undo Tiemann's change to "Handle
11903 initialization of multiple variables by a tuple" - the
11906 Wed Dec 16 11:17:53 1992 Bill Cox (bill@cygnus.com)
11908 * ch-parse.y: complete re-write of DO statement handling.
11909 now operational, except WITH is stubbed out. Improved
11910 syntax error message.
11911 * ch-actions.c: DO support: high_domain_value(), low_domain_value ().
11912 * ch-expr.c: fixes to IN_EXPR handling.
11914 Tue Dec 15 17:15:13 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11916 * ch-grant.c: Add casts to alloca return to avoid compiler warning.
11917 * ch-lex.c: Likewise.
11919 * Makefile.in (ch-lex.c): Delete incorrect free declaration added
11920 by flex to avoid compiler error.
11922 Tue Dec 15 08:41:08 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11924 * ch-decl.c (do_decls): Handle initialization of multiple
11925 variables by a tuple.
11927 * ch-decl.c (do_decls,start_chill_function): Make DECL public
11928 if we're doing a GRANT ALL at top level.
11930 * ch-lang.c (build_range_type): Deal with typecast to CHAR in
11933 * c-typeck.c (digest_init): SET_TYPE is not a scalar type.
11934 BOOLEAN_TYPE and CHAR_TYPE are scalar types.

11938 * ch-lex.l (get_chill_{linenumber,filename}): New functions.
11939 (convert_number): Use LONG_TYPE_NODE instead of INTEGER_TYPE_NODE.
11941 Mon Dec 14 13:36:44 1992 Bill Cox (bill@cygnus.com)
11943 * expr.c: install and test newer Pascal IN_EXPR code,
11944 but don't activate it - it's very verbose.
11946 Mon Dec 14 00:22:49 1992 Fred Fish (fnf@cygnus.com)
11948 * Makefile.in (LANGUAGES): Add chill.

11977 * ch-tree.h: Add declarations for new chill functions that
11978 have been implemented but not (yet) declared.
11980 Sat Dec 12 00:17:23 1992 Per Bothner (bothner@cygnus.com)
11982 * c-typeck.c (process_init_constructor): Warn about duplicate
11983 labels for labelled initializer elements.
11984 * ch-lex.l (various operator tokens, such as "+"): Don't
11985 set yylval.code to a TREE_CODE; this is better done in parser.
11986 * ch-parse.y: Some work with case labels and tuples.
11987 Get literal range as tuple (and case) labels working.
11988 Fix some problems introduced by recent grammar overhaul.

11992 * ch-actions.c, ch-parse.y ch-tree.h ch-expr.c, ch-typeck.c:
11993 got long, real expressions working. We can also call a func-
11994 tion and use its return value.
11996 Thu Dec 10 14:45:17 1992 Per Bothner (bothner@cygnus.com)
11998 * ch-parse.y: Major change to remove or at least identify
11999 parser ambiguities. One result: We now allow actions that
12000 start with '(', as required by teh Blue Book. This does break
12001 some things; look for FIXME for things that need work.
12002 * ch-typeck.c (chill_expand_case_expr): We need an extra
12003 level of looping to (in the future) support <case label
12004 specification>s with more than one <case label list>.

12033 indicate we are done with initialization.
12035 * ch-decl.c (do_decls): Set TREE_PUBLIC if we are doing a
12037 (start_chill_function): Ditto.
12039 * ch-lex.c (convert_bitstring): Set TREE_CONSTANT.
12040 (compiler_directive): Don't confuse compiler directives with
12041 equality comparison operators.
12043 * ch-parse.y: Clear CURRENT_LOCNAMELIST after calling do_decls.

12056 * tree.def: Move CARD_EXPR and SET_LE_EXPR back down with the other
12057 Pascal-required ones, since C++ no longer needs them. When
12058 Chill's public, a comment can be added to the effect that
12059 SET_LE_EXPR is also used by Chill.

12102 (push_newmode,push_synmode): Call `fixup_unknown_type' when we
12103 see a declaration that uses `unknown_type_node'. FIXME.
12105 * ch-grant.c (decode_constant): New function.
12106 (decode_decl): Call `decode_constant' for CONST_DECLs.
12108 * ch-lex.l (char action): Use ridpointers instead of
12109 lookup_name to get "char"'s declaration.
12111 * ch-parse.y: Call `build_lang_decl' instead of `build_decl'
12112 when we need to build a TYPE_DECL.
12114 Tue Dec 2 09:44:05 1992 Bill Cox (bill@cygnus.com)
12116 * ch-typeck.c: clean up a gcc warning with a forward

12122 that are duplicated in c-decl.c
12124 Tue Dec 1 16:38:51 1992 Fred Fish (fnf@cygnus.com)
12126 * ch-actions.c (lang_init): Ifdef out initializations for
12127 __builtin_abs and __builtin_fabs, since they are duplicates of
12128 initializations in c-decl.c, and trigger spurious warnings.
12130 Tue Dec 1 16:35:18 1992 Bill Cox (bill@cygnus.com)
12132 * ch-parse.y: make size() work with a typename argument.

12161 * chillsh: New script frontend (ala g++), installed as "chill".
12162 Can't be called "chill.sh" because make tries to cat it into the
12163 "chill" directory. Can't be called just "chill" cause that's
12164 already there as a directory.
12165 * Makefile.in: Add rules to install chillsh as "chill".
12166 * chill/libchill.c: Temporarily ifdef out stuff that wants
12167 to conflict with i486/SVR4 runtime or wants to pull in librmt.a,
12168 which itself causes linkage to fail.

12172 * ch-lex.l: added keywords for TRUNC, ROUND, FLOAT, LFLOAT
12173 conversion routines.
12174 * ch-parse.y: added %tokens for TRUNC, ROUND, FLOAT, LFLOAT.
12175 Added production for SIZE(expr).

12180 * ch-lex.l, ch-parse.y: Translate token PFEIL into English ARROW.
12181 * ch-parse.y (op6): Remove handling of string repetition operator,
12182 until we can figure out a way to parse it correctly.

12190 * ch-actions.c: removed compile warning, better code for abs.
12192 * ch-parse.y: add productions for builtin functions succ, pred,
12193 abs, and size. Add %tokens also. Sort %tokens alphabetically.
12195 * ch-lex.l: add parsing for builtin function names, such as abs,
12196 pred, succ, etc. Put flex -a option into Makefile.in, so we can
12197 clean up the lexer soon.
12199 Tue Nov 24 14:18:48 1992 Per Bothner (bothner@rtl.cygnus.com)
12201 * ch-typeck.c (chill_handle_case_label, chill_handle_case_default):
12202 New functions, for code common to CASE actions and expressions.
12203 * chill.y: Replace some code by calls to chill_handle_case_label
12204 and chill_handle_case_default.
12205 * ch-typeck.c (chill_expand_case_expr): Add semantics.
12207 * tree.c: Change doing_chill_thang from extern to common.

12211 * ch-tree.def: New CASE_EXPR type, for case expressions.
12212 * ch-expr.c (chill_expand_expr): Hook for CASE_EXPR.
12213 * ch-typeck.c (chill_expand_case_expr): New function.
12214 Placeholder to implement case expressions.
12215 * ch-typeck.c (chill_expand_result, chill_expand_return):
12216 Handle mode-unspecified tuples and case expressions in
12217 the context of RETURN and RESULT actions.
12218 * chill.y (assignaction): Handle case expressions in the
12219 context of the RHS of an assignment action.
12220 * chill.y (caseaction): Remove spurious duplicate OF in grammar.
12221 * chill.y: Handle labeled structure tuples.
12222 * chill.y: New rules to parse CASE expressions.
12223 * tree.c (build_function_types): Allow Chill functions
12224 to return arrays and functions.
12226 Wed Nov 18 13:50:28 1992 Per Bothner (bothner@rtl.cygnus.com)
12228 * ch-typeck.c (chill_expand_tuple): New function. Expand a
12229 tuple (constructor) given an expected (context) type.
12230 * chill.y: Implement 'LHS := TUPLE' using expand_chill_tuple,
12231 using the mode of the LHS and the expected type of the TUPLE.
12232 * chill.y: Implement initialization.
12233 * chill.y: Fix some syntax bugs (forbidlist must be surrounded
12234 by parentheses), and remove or note ambiguities.
12235 * chill.y: Started converting layout style to be like c-parse.in.
12236 * chill.y: Implement IF expressions.
12237 * chill.y: Added syntax rules for tuples. Labelled and unlabelled
12238 array tuples should now work (in some contexts).
12239 * ch-actions.c: Initialize doing_chill_thang to 1.
12240 * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
12241 initializer, to make pushdecl and finish_decl work.
12242 * c-decl.c (convert_for_assignment): If Chill, don't convert
12243 function and arrays into pointers. (Maybe functions should
12244 still be converted?)
12245 * c-typeck.c (grokdeclarator): Allow functions in Chill
12246 to return arrays and functions.
12248 Mon Nov 16 15:40:47 1992 Per Bothner (bothner@rtl.cygnus.com)
