3376 Tue Oct 25 14:11:07 1994 Per Bothner <bothner@kalessin.cygnus.com>
3378 * convert.c (convert): When converting BOOL constant to
3379 bit-string, bit_one_node and bit_zero_node were switched.
3380 * actions.c (chill_expand_assignment): Use force_addr_of,
3381 not build_chill_addr_expr - latter yields bogus error.
3383 Fri Oct 21 14:26:52 1994 Per Bothner <bothner@kalessin.cygnus.com>
3385 * expr.c (build_chill_indirect_ref): Check for POINTER_TYPE (only)
3386 after converting from REFERENCE_TYPE.
3387 * expr.c (build_compare_expr): Convert to common mode *after*
3388 we've checked compatibility.
3390 Fri Oct 21 02:29:15 1994 Wilfried Moser (moser@rtl.cygnus.com)
3392 * lex.l (check_newline): Use getc instead of getlc to read
3393 the filename in a # line name directive to avoid possibly
3394 downcaseing of a filename.

3411 of NUM. NUM delivers the INT derived class.
3413 * grant.c (write_spec_module): Add writing of
3414 <> USE_SEIZE_FILE "x.grt" <>
3415 SEIZE ALL;

3421 * ch-tree.h (convert_from_reference): Add prototype.
3422 * parse.c (parse_name): If the decl is a REFERENCE_TYPE, just

3425 * convert.c (convert): Only call digest_array_tuple if ARRAY_TYPE.
3426 * typeck.c (chill_expand_tuple): Print error if type is
3427 neither array, struct, or powerset.
3429 * expr.c (chill_expand_expr cases CONCAT_EXPR, SET_*_EXPR,
3430 UNDEFINED_EXPR): Call preserve_temp_slots for temp targets.
3431 If target is not MEM, make temp (even if not REG) to simplify
3432 - and don't copy original target to temp target first. (Not needed.)
3434 * lang.c (maybe_objc_comptypes): Just return -1.

3443 timing.c, typeck.c: Change build1 (ADDR_EXPR, ptr_type_node, XX)
3444 to force_addr_of (XX). Add call to mark_addressable where needed

3459 * inout.c (build_chill_readtext): Add check for item is
3460 referable and not READonly. Add processing of BITSTRINGs.
3462 Mon Sep 26 16:19:36 1994 Per Bothner (bothner@kalessin.cygnus.com)
3464 * expr.c (build_chill_descr): Add missing call to mark_addressable.
3465 * loop.c (toop_loop_end_check): Replace build1 (ADDR_EXPR ...)
3466 with call to force_addr_of (which calls mark_addressable).
3467 * expr.c (build_chill_descr, build_chill_inttime): Likewise.
3468 * inout.c (build_chill_writetext): Likewise.
3470 Mon Sep 26 05:19:21 1994 Wilfried Moser (moser@rtl.cygnus.com)

3499 support for UNION_TYPE. (Patch from Wilfried.)
3500 Also, reverse RECORD_TYPE constructor list.

3504 * expr.c (build_concat_expr): Fix calculation of result_size.
3506 Wed Sep 21 00:54:21 1994 Per Bothner (bothner@kalessin.cygnus.com)
3508 Give up on trying to use the cleanup mechanism in stmt.c to
3509 make sure the exception handler get unlinked on goto/exit/return.
3510 Instead, do it ourselves. (Much simpler.)

3554 * loop.c (begin_loop_scope): Move pushlevel from here ...
3555 * parse.c (parse_do_action): ... to here.

3573 * lex.l (readstring): Add processing of control sequence
3574 in character string literals. The granting mechanism writes
3575 this to grant files.

3579 * expr.c (compare_records): In case of -fpack do always
3580 a memcmp instead of comparing each field of the

3592 * tasking.c (get_process_wrapper_name): New function.
3593 (add_taskstuff_to_list): Add a new argument, which is
3594 the entrypoint of a process.
3595 (build_process_header): Change PROCESS arguments to be
3596 like arguments of a function. There will be a wrapper
3597 which is the real entry point for a PROCESS. This wrapper
3598 is automatically build after a PROCESS definition and gets
3599 as argument a pointer to a structure looking like the
3600 arguments of the PROCESS. This wrapper will call the
3601 PROCESS (see build_process_wrapper).
3602 (build_process_wrapper): New function (see above).
3603 (build_start_process): Change processing of arguments.
3604 (tasking_setup): Add processing of a different entry point
3605 in case of PROCESSes.

3614 of PROCESSes, they look now like normal functions.
3616 * decl.c (init_decl_processing): Add declaration of memcmp
3617 function.
3619 * ch-tree.h: Add new prototype for build_process_wrapper,
3620 change prototypes for add_taskstuff_to_list and

3632 generated.
3633 * Makefile.in (GNUCHILL_VERSION): Remove it, its defined in
3634 Make-lang.in.
3636 * chill.in: In case of -fgrant-only pass "-S -o /dev/null"
3637 to the compiler to avoid generation of an object file.
3639 Thu Sep 8 12:07:28 1994 Per Bothner (bothner@kalessin.cygnus.com)
3641 * convert.c (display_int_cst), ch-tree.h: New function.
3642 * convert.c (digest_array_tuple): Use digest_int_cst to
3643 provide better error messages. Return error_mark_node on error.
3644 * grant.c (decode_const): Simplify by using digest_int_cst.
3645 * grant.c (format_character, find_assoc): Removed.
3647 * decl.c (do_decl): Add missing TREE_CHAIN.
3649 * decl.c (finish_incomplete_decl): Removed.
3650 (init_decl_processing): Don't set incomplete_decl_finalize_hook.
3651 (finish_decl): Remove old C-specific code to deduce size of
3652 array from initialization.
3653 (complete_array_type): Just make it abort.
3655 * except.c (finish_handler_array): Avoid calling C-specific kludge
3656 complete_array_type.
3658 * convert.c (digest_constructor): Rename, and re-write to:
3659 (digest_array_tuple, convert): No longer use the code in
3660 ../c-typeck.c; use a Chill-only implementation (sigh).
3662 * typeck.c (chill_expand_tuple): Remove unneeded call to
3663 complete_array_type.
3665 * expr.c (fold_set_expr), grant.c (decode_constant),
3666 typeck.c (expand_constant_to_buffer): Update name of called
3667 function unpack_set_constructor to get_set_constructor_bits.
3668 * expr.c (powersetlen ): Remove redundant call to convert.
3670 * ch-tree.h (unpack_set_constructor): Removed obsolete declaration.
3672 * inout.c (build_chill_writetext): Handle 64-bit integer literals
3673 by trying to convert them to a smaller type.
3675 * lex.l (convert_number): Always use long long type (possibly
3676 unsigned) to avoid problems with constant folding truncation.
3678 Mon Sep 5 08:08:22 1994 Wilfried Moser (moser@rtl.cygnus.com)
3680 * ch-tree.h (enum chill_built_in_function): Add BUILT_IN_QUEUE_LENGTH.
3681 Add new prototype (see tasking.c).
3683 * expr.c (build_generalized_call): Add processing of

3686 * tasking.c (build_queue_length): New function.
3688 * tasking.c (tasking_init): Add new external function definition.
3690 Thu Sep 1 15:38:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3692 * lex.l (default_lex): New function. Progress towards
3693 getting rid of [f]lex.
3695 * lex.l (convert_number): Use mul_double and add_double.
3696 Set result type to a reasonable type in which the literal
3697 will fit. Give error message if literal is too big.
3699 * lex.l (equal_number): Switch (temporarily) to permanent obstack.
3701 * typeck.c (build_chill_slice_with_range): Check for empty
3702 slice *after* we have checked for upper/lower limit in range.

3705 CHAR ranges are represented as INTEGER_TYPEs.)
3707 * tasking.c (build_process_header): Add missing call to
3708 expand_start_bindings.
3709 * parse.c (end_function): Add missing expand_end_bindings.
3711 Wed Aug 31 17:25:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3713 * decl.c (init_decl_processing): Set set_alignment.
3715 Tue Aug 30 16:40:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
3717 * actions.c (print_missing_cases, check_missing_cases,
3718 BITARRAY_TEST, BITARRAY_SET): New functions and macros,
3719 to check for completeness of case actions and expressions.
3720 * decl.c (c_decode_option, init_decl_processing):
3721 Don't set warn_switch.
3722 * expr.c (chill_expand_case_expr): Call check_missing_cases
3723 instead of check_for_full_enumeration_handling.
3724 * parse.c (parse_case_actions): Call check_missing_cases.
3726 * expr.c (build_chill_binary_op): Remove some dead code.
3727 * expr.c (chill_truthvalue_conversion): Call build_chill_binary_op
3728 instead of build_binary_op.
3729 * ch-tree.h (binary_op_error, build_binary_op): Unused. Removed.
3731 * parse.c (end_function): Use kept_level_p in parameter to
3732 poplevel. This reverts a June 13 change.
3734 Fri Aug 26 11:50:19 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3736 * configure: Ignore --without, as ../configure does.

3740 * lex.l: Change rule for decimal numbers to allow identifiers
3741 to start with an underscore (_).

3745 * tasking.c (build_receive_signal_case_label): Remove backwards
3746 chill_convert_for_assignment (which converted whatever garbage
3747 was in the *target* to the type of the signal argument!).
3749 Fri Aug 19 07:10:43 1994 Wilfried Moser (moser@rtl.cygnus.com)
3751 * inout.c (build_chill_io_list_type, build_enum_tables),
3752 tasking.c (build_tasking_struct): Temporarily reset
3753 maximum_field_alignment to 0, so that the compiler-built
3754 data structures needed by the RTS can be independent of -fpack.
3756 Thu Aug 18 13:39:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3758 * typeck.c (build_init_struct): Temporarily reset
3759 maximum_field_alignment to 0, so that the compiler-built
3760 data structures needed by the RTS can be independent of -fpack.
3762 Wed Aug 17 23:48:33 1994 Wilfried Moser (moser@rtl.cygnus.com)
3764 * parse.c (parse_primval, expect, parse_on_exception_list):
3765 Print error message only in pass 2.
3767 Wed Aug 17 13:47:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3769 * decl.c (switch_to_pass_2): Revert June 13 change,

3772 * ch-tree.def (SLICE_EXPR): New tree-code.
3773 * typeck.c (build_chill_slice): For building a slice of a
3774 bit-string, just generate a SLICE_EXPR.
3775 * decl.c (init_decl_processing): Declare __pscpy.
3776 * actions.c (chill_expand_assignment): Handle a SLICE_EXPR
3777 on the LHS of assignment, by calling __pscpy.
3778 * expr.c (chill_expand_expr): Handle SLICE_EXPR (as a RHS
3779 value) by using __psslice to copy slice to a temp.
3781 Wed Aug 17 05:52:44 1994 Wilfried Moser (moser@rtl.cygnus.com)
3783 * Make-lang.in: Change version of GNUCHILL compiler to 1.4.1.
3784 * expr.c (build_chill_length): Enable LENGTH built-in to process
3785 Buffers and Events too (Z.200/1992).
3786 * lex.l (yywrap): Always set yyin to finput and/or grt_in. On
3787 a linux system the previous version was not able to run.
3788 * tasking.c: Correct processing of infinite buffer- and event-length
3789 to avoid RANGEFAIL warning.
3791 Thu Aug 11 11:46:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3793 * parse.c (parse_if_expression_body): Don't call the C-specific
3794 build_conditional_expr. Just do build_nt (COND_EXPR, ...).
3795 * convert.c (convert): Convert a COND_EXPR by converting
3796 each branch.
3798 * convert.c (convert): Don't call convert before
3799 convert_to_reference. It's apt to do weird and unneedful things.
3800 * convert.c (convert): If the expression is varying, just call
3801 varying_to_slice, which simplifies quite a bit.
3803 * ch-tree.h (varying_to_slice): Add prototype.
3804 * typeck.c (varying_to_slice): Remove prototype.
3806 * satisfy.c (satisfy): Move case PAREN_EXPR from type 'e'
3807 to type '1'.
3809 * except.c (emit_setup_handler): Temporarily reset the
3810 maximum_field_alignment to zero so the compiler's exception
3811 data structures can be compatible with the run-time system,
3812 even when we're compiling with -fpack.
3814 * expr.c (compare_records): Call saved_if_needed on operands.
3816 * expr.c (build_set_expr case NE_EXPR): Don't use __nepowerset
3817 which has been reimplemented to just call __eqpowerset and
3818 invert the result. Inline this new implementation by
3819 handling as EQ_EXPR, and inverting the result.
3820 * decl.c (init_decl_processing): Don't define unused __eqpowerset.
3822 * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
3823 type boolean_type_node, not void_type_node. (Fixing this
3824 avoids a crash in the back-end.)
3826 * grant.c (decode_constant): In a CALL_EXPR, if the argument
3827 list is not a TREE_LIST (as in string repetiation), don't
3828 emit parentheses.
3830 Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3832 * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
3833 CONST_DECL is from a SET definition. (This is safer than
3834 checking that the type is ENUMERAL_TYPE, because synonym
3835 definitions may have a NULL TREE_TYPE.)
3836 Also, if we have duplicate enums whose types are identical,
3837 this is an error.
3838 * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
3839 an extra 'quiet' parameter, which is true if we're called from
3840 bind_sub_modules. (In that case an error message about duplicated
3841 decls would be repeated later, so suppress it.)
3843 * parse.c (stmt_count): Removed, not used.
3844 (INIT_ACTION): Call emit_line_note only if !ignoring.
3845 (parse_begin_end_block): Do INIT_ACTION even if ignoring.
3847 Fri Aug 5 12:39:11 1994 Per Bothner (bothner@kalessin.cygnus.com)
3849 * parse.c (parse_untyped_expr): Add missing semi-colon.
3851 Thu Aug 4 17:40:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
3853 * parse.c (parse_untyped_expr): Fix various problem for the
3854 case that we see a '(': Add missing 'case' keyword.
3855 Only recurse if '(' is followed by 'if', 'case' or '[',
3856 and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
3858 * parse.c (parse_send_action): Remove extra nreverse.
3860 Thu Jul 28 04:00:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3862 * expr.c (build_allocate_global_memory_call, build_allocate_memory_call):
3863 Add new checks.
3865 Tue Jul 26 22:48:15 1994 Michael Tiemann (tiemann@blues.cygnus.com)
3867 * parse.c (parse_untyped_expr): Added missing "case" before LPRN.
3868 Added a missing call to `require' as well.
3870 Tue Jul 19 10:30:12 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3872 * lex.l (yywrap): Define as yywrap_chill to avoid conflicts with
3873 the extern declaration in the flex skeleton.
3875 Mon Jul 18 23:06:04 1994 Per Bothner (bothner@kalessin.cygnus.com)
3877 * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
3878 Check the type of the instance expr using CH_COMPATIBLE,
3879 and not just == instance_type_node. (This allows
3880 the expression to have mode READ INSTANCE).
3881 * tasking.c (build_instance_type): Give instance_type_node
3882 a non-null novelty (i.e. different from a struct).
3883 * tasking.c (build_receive_case_start, build_delay_case_start):
3884 Check that for a location using CH_LOCATION_P.
3886 Mon Jul 18 13:22:23 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
3888 * expr.c (finish_chill_unary_op): Use TREE_SET_CODE not TREE_CODE
3889 to modify a tree code.
3891 Mon Jul 18 11:24:57 1994 Bill Cox (bill@rtl.cygnus.com)
3893 * convert.c (digest_structure_tuple): Fix thinko in TREE_CODE
3894 comparison.
3896 Mon Jul 18 05:40:15 1994 Doug Evans (dje@canuck.cygnus.com)
3898 * decl.c (warn_bad_function_cast): Define so cc1chill will link.
3900 Thu Jul 14 18:37:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3902 * parse.c (parse_send_action): Do tree_cons *before* checking
3903 for end of loop.
3905 Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3907 * convert.c (digest_structure_tuple): Don't use convert to
3908 coerce initial value, use chill_convert_for_assignment instead.
3909 (Thus we also get range_checking.)
3911 * expr.c (build_chill_card): Use force_addr_of instead of
3912 build_chill_addr_expr.
3914 * loop.c (build_temporary_variable): Stylistic tweak.
3915 * loop.c (maybe_make_for_temp): Initialize temp using
3916 explicitly, not using assignment. Avoids a problem if
3917 the expression is read-only.
3918 * typeck.c (smash_dummy_type): Always used the saved TYPE_NAME
3919 and CH_NOVELTY_FLAG.
3921 Wed Jul 6 20:12:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3923 * expr.c, ch-tree.h (finish_chill_unary_op): New function,
3924 based on code ripped out of build_chill_unary_op.
3925 (build_chill_unary_op): Call finish_chill_unary_op unless pass==1.
3926 * satisfy.c (satisfy): Call finish_chill_unary_op when needed.
3928 Mon Jun 27 11:29:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3930 * tree.c (save_if_needed), ch-tree.h: New function.
3931 * typeck.c (build_chill_slice_with_range,
3932 build_chill_slice_with_length): Call save_if_neeed on array arg.
3933 * expr.c (varying_to_slice): Re-write to use save_if_needed.
3935 * typeck.c (extract_constant_from_buffer): Handle BOOLEAN_TYPE.
3937 Mon Jun 27 01:11:10 1994 Wilfried Moser (moser@rtl.cygnus.com)
3939 * inout.c (build_chill_io_list_type): Change layout of __tmp_WIO_list
3940 that it is always the same, regardless if compiled with -fpack
3941 or not.
3943 Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3945 * lex.l (yywrap): Kludge to work around mis-synchronization
3946 between lexer (which read ahead) and parser: Don't emit
3947 (left-over) uze_seizefile directives at the end of file.
3949 * typeck.c (build_chill_array_ref): Allow the derived
3950 array indexing syntax for arrays of bit strings.
3951 Add a comment explaining why.
3953 * typeck.c, ch-tree.h (string_assignment_condition): Change
3954 the interface. Return a boolean expression (which can be
3955 used in a conditional at run-time); never expand anything.
3957 * actions.c (chill_convert_for_assignment): Check
3958 string_assignment_condition here, rather than in callers.
3959 * actions.c (chill_expand_assignment): Don't need to check
3960 string_assignment_condition here.
3961 * expr.c (build_chill_function_call): Likewise.
3962 * satisfy.c (safe_satisfy_decl): Update accordingly.
3963 * decl.c (do_decl): Simplify testing and conversion by
3964 deferring everything to chill_convert_for_assignment.
3966 * parse.c: Combine the two variables 'ignore_exprs' and
3967 'ignore_actions' into one variable called 'ignoring'.
3968 * ch-tree.h: Add 'extern int ignoring'.
3969 * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
3970 Rename ignore_actions and ignore_exprs to ignoring.
3971 Remove unneeded extern declarations.
3972 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3973 build_chill_arrow_expr, build_generalized_call, build_delay_action,
3974 build_buffer_type, build_event_type): I changed my mind. It is
3975 cleaner to check for 'ignoring' in the parser, rather than here.
3976 * parse.c (parse_action, parse_primval, parse_opt_mode):
3977 Therefore we must check for ignoring here.
3978 * parse.c (parse_loc_declaration): Set ignoring in pass 2
3979 when parsing the mode.
3981 * tasking.c (generate_tasking_code_variable): Do arithmetic
3982 on signal_code etc using unsigned rather than signed shorts.
3984 * grant.c (static char* current_grant_modename): Removed.
3985 * grant.c (decode_decl case CONST_DECL): Remove error message.
3987 * Make-lang.in (CHILL_SRCS): Add $(srcdir)/ch/parse.c.
3988 * Makefile.in: Fix dependencies for parse.o.
3989 Remove some duplicate dependencies for $(TREE_H).
3991 Mon Jun 13 14:25:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3993 * typeck.c (build_chill_cast): Allow a value cast between
3994 non-discrete object of the same size, but with a pedwarn.
3995 * typeck.c (bit_string_assignment_condition,
3996 char_string_assignment_condition): Merge near-duplicate functions
3997 and place the code in string_assignment_condition.
3999 * decl.c (parm_flag, declare_parm_level, in_param_level_p):
4000 Removed. Not used.
4001 * decl.c (start_chill_function, finish_chill_function): Make
4002 parameter level have same nesting level as body, as required by Z200.
4003 * decl.c (switch_to_pass_2): Always exit if an error has been found.
4004 * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
4005 generated from GRANT ALL.
4006 * decl.c (lookup_name_for_seizing): Don't seize from
4007 the nesting level of builtins (predefined objects).
4008 * decl.c (lookup_name_for_seizing): Make more robust on error.
4010 * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
4011 be 'RESULT' (or 'result'). This makes it more accessible from gdb.
4012 Also, use do_decl to declare it, so that debugging symbols are
4013 generated. And, re-arrange so that actions that need to
4014 be done both passes (such as push_levels) use the same code.
4016 * parse.c (get_type_of): If ignore_exprs, don't lookup name.
4017 * parse.c (end_function): Fix poplevel params.
4018 * parse.c (expect): Don't read forwards on an error.
4019 * parse.c (parse_field): Don't define two tag_list locals!
4020 * parse.c (parse_pass_1_2): Better error message.
4022 * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
4023 parse_opt_mode, rather than vice versa. If parse_opt_mode
4024 returns NULL_EXPR, then parse_mode gives an error.
4025 Change parse_opt_mode (and any functions it calls) to only
4026 return NULL_TREE if there is no mode (even on ignore_exprs).
4027 (parse_set_mode, parse_structure_mode, parse_procedure_mode):
4028 Never return NULL_EXPR.
4029 * tasking.c (build_buffer_type, build_event_type): Return
4030 void_type_node instead of NULL_EXPR if ignore_exprs is true.
4032 * parse.c (parse_synonym_definition): Call parse_untyped_expr
4033 only if we have a mode.
4034 * parse.c (parse_send_action): Parse list of untyped_expr's,
4035 rather than a list of (typed) expressions.
4036 * parse.c (parse_primval): Emit error if '[' seen without
4037 preceding mode name. (If this is to be allowed, call
4038 parse_untyped_expr instead.)
4040 * parse.c (parse_array_index): Renamed to ...
4041 (parse_index_mode): ... to match Z200 terminology.
4042 Re-write to resolve some of the nastier ambiguities,
4043 and allow things like ' CHAR(10) : CHAR(20) '.
4045 * parse.c (parse_tuple_element): Change interface to return
4046 reversed list, so don't call nreverse.
4047 * parse.c (parse_tuple): No longer nreverse element list here.
4048 * parse.c (parse_opt_element_list): Do nreverse here instead.
4049 * parse.c (parse_case_label_list): Call nreverse at end.
4051 Fri Jun 10 15:36:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
4053 * typeck.c (chill_similar): Remove bogus "else".
4055 Wed Jun 8 00:01:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
4057 * ch-tree.h (TYPE_ARRAY_MAX_SIZE): New macro (and comment)
4058 to make it clearer that we are using TYPE_MAX_VALUE in a special way.
4059 * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
4060 * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
4061 * convert.c (convert): When converting a fixed string/array
4062 to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
4063 of (the type of) the padding.
4064 * convert.c (convert): If the concatenation is non-constant, use
4065 the low-level 'build' to set the type of the result (which is usually
4066 a fixed-size array) rather than depend on build_chill_binary_op
4067 to figure it out (it's unable to simplify the size to a constant).
4069 Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
4071 * lang.c (lang_decode_option): Let -fspecial_UC imply
4072 -fno-ignore-case without requiring it explicitly.
4073 * lang.c (lang_decode_option): Support (experimentally)
4074 the -fpack and -fno-pack flags.
4076 Thu Jun 2 20:49:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4078 * configure: Add support for --program-prefix and --program-suffix.
4080 Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
4082 * convert.c (digest_constructor): Check that initial value
4083 is compatible with element mode before calling convert.
4084 * typeck.c (chill_compatible): A string mode is not compatible
4085 with an untyped constructor.
4086 * decl.c (do_decl): Clean up error messages. Use error_with_decl.
4088 * ch-tree.h: Fix inconsistencies: bool_true_node ->
4089 boolean_true_node, and bool_false_node -> boolean_false_node.
4090 * typeck.c (valid_array_index_): Minor simplification.
4092 Tue May 31 04:33:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
4094 * inout.c (build_chill_writetext): Add correct processing
4095 of POWERSET RANGE (setmode).
4097 * lex.l (same_file): Add searching for file(s) in
4098 seize_path_list.
4100 Fri May 27 14:22:42 1994 Per Bothner (bothner@kalessin.cygnus.com)
4102 * Make-lang.c (CHILL.mostlyclean, CHILL.distdir): Don't list
4103 yacc/bison output files, since the grammer is no longer in yacc.
4104 * config-lang.in (diff_excludes): Likewise.
4106 Thu May 26 16:38:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
4108 * gperf, hash.h, lex.l, parse.h: Rename PROCESS_TYPE token
4109 (in some files spelled PROCESS_TYPE_ to avoid clashes
4110 with the PROCESS_TYPE tree_code) to PROCESS_TYPE_TOKEN.
4112 Thu May 26 02:18:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
4114 * timing.c (build_cycle_start): Change call to __define_timeout.
4115 * decl.c (init_decl_processing): Change definitions of
4116 __define_timeout and __wait_timeout.
4118 Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
4120 Replace yacc-based parser with a recursive-decent parser.
4121 (This may seem backwards, but Chill [like C++] is not a
4122 language that is remotely LALR(1). Using a R-D parser
4123 allows us to use look-ahead and to back-up to resolve the
4124 difficult ambiguities.)
4125 * parse.y: Removed.
4126 * parse.c, parse.h: New files, containing new r-d parser.
4127 * Makefile.in: Update accordingly.
4128 * actions.c (chill_convert_for_assignment): Don't return
4129 NULL_EXPR if ignore_exprs is true. It simplifies the parser
4130 if we consistently reserve NULL_EXPR for a missing expression.
4131 * expr.c (build_chill_function_call): Likewise.
4133 * lex.l: Tweaks for new parser.
4134 * lex.l (prepare_paren_colon, paren_paren_colon_level,
4135 paren_level): Ugly hack no longer needed.
4137 * expr.c (build_chill_function_call): Cleanup.
4138 Call chill_convert_for_assignment to convert IN/INOUT
4139 paramaters on both input and output. For LOC parameters,
4140 give error if actual is a non-referable location.
4141 * actions.c (convert_for_assignment): Add new parameter (a
4142 "place" string used in error messages).
4143 * actions.c (adjust_parm_or_field): Removed.
4144 * actions.c (chill_expand_assignment): Take just a single LHS,
4145 and move support for multiple assignments to ...
4146 (expand_assignment_action): ... here. Some cleaning up.
4147 * timing.c (build_cycle_start): Adjust accordingly.
4148 * actions.c (expand_assignment_to_varying_array): Likewise.
4149 * tasking.c (many places): Ditto.
4150 * ch-tree.h: Fix declarations appropriately.
4152 * parse.c (parse_defining_occurrence_list): Return a single
4153 IDENTIFIER_NODE (instead of a singleton list) in the common
4154 case. Minor complication to save a minor amount of space.
4155 * decl.c (do_based_decls): Move guts of code into ...
4156 (do_based_decl): ... this new function.
4157 * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
4158 * decl.c (push_syndecl): Replace by ...
4159 (push_syndecl): ... (which only supports a single name).
4160 (push_modedef): Only handle a single name.
4161 * tasking.c (build_process_header, build_signal_struct_type):
4162 Adjust accordingly.
4164 * expr.c (build_generalized_call): Handle string repetition.
4165 * expr.c (build_chill_repetition_op): Change interface.
4166 * grant.c (decode_constant): Allow parameter list to be
4167 a non-TREE_LIST. (Used for string repetition.)
4169 Wed May 25 11:28:48 1994 Per Bothner (bothner@kalessin.cygnus.com)
4171 * lex.l (make_identifier): Replaced by ...
4172 (read_identifier, handle_name): ... new functions.
4173 * lex.l: Parse an identifiers using read_identifier using
4174 read_identifier and handle_name, rather than having [f]lex
4175 do it. (One reason is that lex uses a fixed-size buffer.)
4177 * lex.l (read_directive, skip_directive): New functions.
4178 Use them to parse compiler-directives, instead of rather
4179 ugly and useless use of lexer start conditions.
4181 Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4183 * decl.c (unnamed_module_number): Renamed to ...
4184 (module_number): .. and make non-static.
4185 (push_module): Always increment module_number.
4186 * lex.l (yywrap): Print warning if no modules seen.
4188 * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
4189 decl to current_seizefile_name (which is unreliable).
4190 * grant.c (chill_grant): Set it here instead.
4192 * expr.c (fold_set_expr): Use int_size_in_bytes instead of
4193 TYPE_PRECISION (which is not defined for a SET_TYPE).
4195 Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
4197 Cleanup to remove need for variables in common storage.
4198 * decl.c: Remove unused use of current_obstack.
4199 * actions.c (maybe_chill_check_decl): Remove unused function.
4200 * actions.h, lang.c: Remove uses of doing_chill_thang.
4201 * ch-tree.h (void_list_node): Make extern (rather than common).
4202 * decl.c (void_list_node): Add definition.
4204 Thu May 19 06:54:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
4206 * configure (build): Build canon_host and canon_target
4207 to pass it to all subsequently generated Makefiles (needed
4208 for testsuite/execute in case of cross build).
4210 Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4212 * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
4213 the input type, which loses with the no-longer-new 2-pass
4214 implementation, since the input "type" could be an IDENTIFIER_NODE.
4215 * grant.c (raw_decode_mode): Rename to decode_mode.
4217 Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
4219 * typeck.c (chill_location): Neither a STRING_CST nor a
4220 CONSTRUCTOR is a location.
4221 * typeck.c (chill_root_mode): Convert a function to a
4222 pointer-to-function.
4223 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
4224 build_chill_arrow_expr): If ignore_exprs, return operand
4225 rather than NULL_EXPR. This makes it easier for the parser to
4226 distinguish missing expressions.
4227 * expr.c (build_max_min): Convert the lower bound of a
4228 set to a long before calling run-time routine.
4229 * expr.c (build_chill_pred_or_succ): Use discrete_type_p
4230 to check the argument type.
4231 * expr.c (build_chill_arrow_expr): If argument is not a location,
4232 do a predwarn if it is a STRING_CST or has function type.
4234 Tue May 17 06:05:13 1994 Wilfried Moser (moser@rtl.cygnus.com)
4236 * configure (build): Remove building of canon_host and canon_target.
4237 It doesn't work in any case.
4239 Mon May 16 02:10:35 1994 Wilfried Moser (moser@rtl.cygnus.com)
4241 * configure (build): Build canon_host and canon_target
4242 to pass it to all subsequently generated Makefiles (needed
4243 for testsuite/execute in case of cross build).
4244 * Make-lang.in (chill-runtime): Change chill to CHILL in the case
4245 statement to build chill-runtime automatically.
4247 Mon May 9 15:30:08 1994 Doug Evans (dje@canuck.cygnus.com)
4249 * Makefile.in (FLAGS_TO_PASS): Define.
4250 (OBJDEPS): Define.
4251 (../cc1chill): Depend on $(OBJDEPS) $(C_OBJS).
4252 * Make-lang.in (cc1chill): Delete dependency on $(OBJS) $(BC_OBJS).
4253 (CHILL.mostlyclean): Use `mostlyclean' as recursive target.
4255 Sun May 8 13:05:00 1994 Per Bothner (bothner@cygnus.com)
4257 * Make-lang.in (cc1chill): Should not depend on libgcc.a.
4259 Thu May 5 18:58:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
4261 * decl.c (copy_lang_decl): New (dummy) function.
4263 Mon May 2 14:33:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
4265 * parse.y (sendaction): Fix thinko (in sense of condition).
4266 * tasking.c (build_receive_case_label): Another thinko.
4268 * parse.y (optsigdest): Force ignore_exprs to 0 while parsing
4269 the (signal-)name.
4271 * decl.c (build_chill_function_type): Don't call layout_type
4272 (since that may prevent parameter or result types being
4273 properly satisfied).
4274 * satisfy.c (satisfy): Layout FUNCTION_TYPEs.
4275 * parse.y (procmode): Call build_chill_pointer_type, rather
4276 than build_pointer_type (which incorrectly sets TYPE_SIZE).
4278 * parse.y (get_type_of): Handle TYPE_DECL (again).
4279 * parse.y (optresultspec): Call build_chill_reference_type, rather
4280 than build_reference_type (which incorrectly sets TYPE_SIZE).
4281 * parse.y (range_or_mode): Rename to plain range, since it
4282 no longer matches modename.
4283 * actions.c (chill_handle_case_label_range): New function, with
4284 functionality moved out of chill_handle_case_label.
4285 * actions.c (chill_handle_case_label): Handle here the case that
4286 the label_value is a TYPE_DECL (modename). Also clean up some.
4287 * typeck.c (build_chill_slice_with_length): Convert max_index
4288 to the type of min_value. (Old code broke on varying strings.)

4299 * lex.h, lex.c: Remove lastiddecl.
4300 * lex.l (name_type_signal): Simplify. We no longer check for
4301 TYPENAME or SIGNALNAME (which was unreliable with two passes).
4302 Also rename to make_identifier.
4303 * parse.y: Cleaned up grammar to not need SIGNALNAME or TYPENAME.

4310 * parse.y (name): Do name lookup here (and not in location).
4311 * parse.y: Replace most uses of NAME by higher-level non-terminals:
4312 simple_name_string, name_string, defining_occurrence, or name.

4318 and return type. Moved stuff here (from the parser).
4319 * tasking.c (struct rc_state_type): Removed had_errors.

4327 * parse.y (ioindexmode): Removed; use index_mode instead.
4328 * expr.c (build_generalized_call): If args is a RANGE_EXPR,
4329 we have either a slice or a range mode, depending on func.
4330 * parse.y (index_mode): If we got an 'expr', only allow a name,
4331 or a range mode.
4332 * parse.y (call): A slice with both end points can be a range
4333 mode, so defer handling to build_generalized_call (or index_mode).
4335 * typeck.c (build_chill_slice_with_length): Fix type-checking.
4336 * typeck.c (chill_novelty): Undo (part of) change of April 28:
4337 The novelty of a range mode is the novlety of the parent.
4338 * typeck.c (chill_root_mode): Don't return integer_type_node
4339 if argument has non-nil novelty.
4341 * decl.c (global_bindings_p): Return -1 as true, for the sake
4342 of variable_size (in ../stor-layout.c).
4344 Fri Apr 29 13:42:43 1994 Per Bothner (bothner@kalessin.cygnus.com)
4346 * parse.y: Remove TYPENAME and modename. These are now plain
4347 NAMEs. Modify parsing actions appropriately.
4348 * expr.c (build_generalized_call): Handle the case that
4349 TREE_CODE (func) == TYPE_DECL (as in a cast).
4350 * lex.l (name_type_signal): Never return TYPENAME.
4351 * parse.y (get_type_of): If pass 1, just return the argument.
4353 * decl.c (do_decl): If an initializer has the wrong type,

4400 * typeck.c (smash_dummy_type): Handle the special case of a
4401 NEWMODE of a range mode, as required by Z200, by creating a
4402 new parent mode with the new novelty (and casting the min
4403 and max of the range to teh new parent mode).

4442 * lex.l (yywrap): Move check for circularly seizeing current
4443 grant-file from here ...

4741 * actions.c (chill_expand_assignment): Correct detection of
4742 string assignment case.
4743 * expr.c (chill_expand_expr): Now that we're using build_chill_function_call,
4744 the actual parameters need to be converted to the unsigned long
4745 type explicitly. Do that.

4754 * satisfy.c (safe_satisfy_decl): Add range-check for a SYN's value.
4756 Mon Mar 21 13:29:23 1994 Per Bothner (bothner@kalessin.cygnus.com)
4758 * typeck.c (layout_chill_range_type): Instead of tree_int_cst_lt
4759 use compare_int_csts (which is more robust when signedness differs).
4760 Also, convert the bounds *after* doing range checking.
4762 * ch-tree.def (SET_IN_EXPR): New.
4763 * expr.c (chill_expand_expr): Code to expand SET_IN_EXPR,
4764 moved from expand_expr in ../expr.c. Also add some extra
4765 conversions (because we're now using build_chill_function-call).

4785 convert, to get the range-checking.
4786 * expr.c (build_chill_pred_or_succ): Fix up rangefail code.
4787 Generate a compile-time message if possible.
4788 (build_compare_expr): Comment out compatibility test - should
4789 not be needed in here. Fix a couple of typos. Add some types
4790 to some build calls.
4792 Sun Mar 20 11:48:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
4794 * decl.c (init_decl_processing): Clean up parameter type
4795 list for __setbitpowerset,
4797 * typeck.c (chill_compatible_classes): Allow the M-reference
4798 to be compatible with the N-value class, with suitable M and N.
4799 * typeck.c (build_chill_slice): Don't smash a void TREE_TYPE.
4800 (We don't need to, and it causes confusion.)
4802 * expr.c (build_compare_expr): Fix thinko. Add save_exprs.
4804 * expr.c (build_compare_expr): Fix a transcription bug
4805 (for converting NULL INSTANCEs). Also #include convert.h.
4807 * expr.c (compare_int_csts): New. Compare INTEGER_CSTs.
4808 Works even if their types have different TREE_UNSIGNED.
4809 * expr.c (finish_chill_binary_op): Moved code dealing with
4810 the comparison operators from here ...
4811 * expr.c (build_compare_expr): ... to new function here.
4812 Also, for discrete types, tries to Do The Right Thing, even for
4813 differing values of TYPE_PRECISION and TREE_UNSIGNED.
4814 the code from lay
4815 * ch-tree.h: Declare new functions.
4816 * typeck.c (valid_array_index_p): Various cleanups,
4817 including using new build_parse_expr.
4818 * parse.y: Use new build_compare_expr.
4820 * inout.c (build_chill_writetext): Handle REFERENCE_TYPE args.
4822 Sun Mar 20 08:54:27 1994 Bill Cox (bill@rtl.cygnus.com)
4824 * actions.c (expand_assignment_to_varying_array):
4825 Call build_chill_array_ref to get index checking.
4826 (chill_convert_for_assignment): Delete unused errstr
4827 variable.
4828 (chill_expand_assignment): Call build_chill_array_ref
4829 to get runtime index checking.

4831 to varying_array_index_p.
4832 * ch-tree.h (varying_array_index_p): New proto.

4836 to have consistent operand types.
4837 * typeck.c (valid_array_index_p): Change interface to pass
4838 validity conditions back on caller's TREE_LIST. We
4839 cannot link the conditions to anything which a
4840 layout_type routine will expand, since that will occur
4841 before the exception handler is set up.
4842 Change calls to valid_array_index_p also.
4844 Fri Mar 18 14:40:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
4846 * actions.c, except.c, loop.c, tasking.c: Call
4847 build_chill_function_call instead of the C-specific
4848 build_function_call.
4849 * except.c (initialize_exceptions): Fix parmtype of __builtin_setjmp.
4850 * loop.c (top_loop_end_check): Coerce library function arg.
4851 * convert.c, expr.c: Re-write to avoid calls to C-specific
4852 function build_unary_op (e.g. by calling build1 directly).
4854 * typeck.c (chill_equivalent): Change to force failure
4855 for non-matching integral types (even if not ranges).
4857 * typeck.c, ch-tree.h (build_chill_slice): Make non-static.
4858 * expr.c (varying_to_slice): Call build_chill_slice (and not
4859 build_chill_slice_with_length, which does bunches of range
4860 checking and does not allow the length to be zero).
4861 * convert.c (convert): Fix off-by-one error.
4862 * actions.c (chill_expand_array_assignment): Minor cleaning up.
4864 Fri Mar 18 00:12:48 1994 Per Bothner (bothner@deneb.cygnus.com)
4866 * decl.c (init_decl_processing): __lepowerset and __ltpowerset
4867 take *two* pointer parameters, not one.
4868 * satisfy.c (satisfy): Only call the appropriate layout routine
4869 if TYPE_SIZE is 0 (i.e. type hasn't already been laid out).
4870 * typeck.c (build_chill_slice_with_length): Fix Bill's previous fix.
4872 Thu Mar 17 17:29:43 1994 Bill Cox (bill@rtl.cygnus.com)
4874 * expr.c (build_chill_function_call): Give function call the correct
4875 type tree.
4876 * typeck.c (build_chill_slice_with_length): Restore dynamic range
4877 checking, so it doesn't obscure the CONSTANTness of the length.
4879 Wed Mar 16 17:23:31 1994 Per Bothner (bothner@kalessin.cygnus.com)
4881 * typeck.c (build_chill_slice), expr.c (chill_expand_expr
4882 [case CONCAT_EXPR]): Remove kludge setting slice size upper bound
4883 in TYPE_LANG_SPECIFIC, and restore kludge setting it in MAX_VALUE.
4884 * typeck.c (build_chill_slice): Use TYPE_MAX_VALUE of
4885 array_type if needed for size upper bound of slice_type.
4886 * expr.c (build_concat_expr): Improve calculation of size upper bound.
4888 * typeck.c (valid_array_index_p): Check compatibility using
4889 correct types.
4890 * typeck.c (build_chill_slice_with_length); For now revert
4891 calling valid_array_index_p on length. (It makes it harder
4892 to realize when the slice is constant length.)
4893 * expr.c (build_chill_indirect_expr): Minor tweak. (This
4894 seems to work around a weird C compiler bug. ??)
4896 * expr.c (build_chill_function_call): Cleanup so it doesn't
4897 call build_function_call (in c-typeck.c).
4898 * typeck.c, expr.c: Use build_chill_function_call instead of
4899 build_function_call (in c-typeck.c).
4901 * parse.y (discrete_mode): Move some of the rules from
4902 non_array_mode into new non-terminal.
4903 (arrayindex): Use discrete_mode (with NAME and TYPENAME) to
4904 avoid some misparses.
4905 * ch-tree.h (SLICE_PTR, SLICE_LENGTH): Removed; unused.
4906 * convert.c (digest_structure_tuple): Add missing parameter.
4907 * decl.c (comptypes): Remove unused prototype.
4908 * decl.c (build_chill_function_type): Handle NULL return_type
4909 correctly (convert to void_type_node).
4910 * decl.c (init_decl_processing): layout boolean_type_node *after*
4911 we've set it's TYPE_MIN_VALUE and TYPE_MAX_VALUE.
4913 Wed Mar 16 16:08:22 1994 Bill Cox (bill@rtl.cygnus.com)

4916 * convert.c (convert): Correct calculation of padding length.
4917 * decl.c (grok_chill_fixedfields): Move ignore_exprs test to
4918 parse.y where it belongs. This permits the removal of a kludge
4919 in make_process_struct.
4920 * lex.l, parse.y: Call to_global_level for several errors. Add
4921 code to output error in only one pass.
4922 * tasking.c (make_process_struct): Delete kludge inserted on
4923 March 8.
4924 (build_receive_case_end): Add Wilfried's check for errors.
4926 Tue Mar 15 08:42:12 1994 Bill Cox (bill@rtl.cygnus.com)

4930 (expand_varying_length_assignment): call valid_array_index_p.
4931 rather than validate_varying_array_ref.
4932 * ch-tree.h: Fix prototype for valid_array_index_p.
4933 * expr.c (chill_expand_expr): Call build_chill_array_ref to get
4934 index validation.
4935 (build_hill_lower, build_chill_upper): Return value now inherits
4936 the novelty of the input parameter.
4937 (varying_to_slice): Use CH_NOVELTY macro rather than calling
4938 chill_novelty directly.
4939 * grant.c (newstring): Make len unsigned and cast xmalloc parameter
4940 to unsigned.
4941 (print_integer_type): Pass string value as APPEND's second parameter.
4942 (decode_decl): Pass a boolean expression as print_proc_tail's
4943 first parameter.
4944 (chill_finish_module_code): Make xmalloc's parameter unsigned.
4945 * lex.l: Pass sizes to xmalloc as unsigned ints. Pass second
4946 parameter to in_word_set as unsigned.
4947 * loop.c (build_loop_start): Check top_loop_end_check return value.
4948 * parse.y: Add casts to int for third do_decls parameter, fifth
4949 build_loop_iterator parameter, etc.
4950 * tasking.c (build_receive_case_end): Chack cond_stack before popping.
4951 * typeck.c (validate_varying_array_ref, chill_max_vary_array_index,
4952 valid_array_index): Delete them. They're now unused.

4954 array index is checked.
4955 (build_chill_slice): Restore old functionality where varying_to_slice
4956 is called to handle slices of varying arrays, rather than handling
4957 handling them here.
4958 (build_chill_slice_with_range, build_chill_slice_with_length):
4959 Check range limits for TREE_CONST before calling tree_int_cst_lt.
4960 Delete now-obsolete checks of constant indices.
4962 Mon Mar 14 17:26:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4964 * parse.y (modeless_expr): New rule to allow ([...]) and (if...)
4965 to count as untyped_exprs. (This is not really permitted by the
4966 Blue Book, but has been requested by customers.)
4968 Thu Mar 10 10:11:02 1994 Bill Cox (bill@rtl.cygnus.com)
4970 * chill.texi: Document new command-line options.
4971 * expr.c (build_chill_num): Set unsigned parameter for
4972 type_for_size call correctly (unsigned for enums).

4974 enable/disable runtime range-checking.
4975 * lex.l: Eat more whitespace.
4977 Thu Mar 10 09:41:37 1994 Bill Cox (bill@rtl.cygnus.com)
4979 * Makefile.in: Have rules to make parse.h, y.tab.c and other
4980 derived files. This allows the gcc/configure list of CHILL
4981 files machinery to work.
4982 * ch-tree.h (permanent_allocation): Add a parameter flag.
4983 * decl.c (finish_chill_function, finish_decl): Provide the
4984 new permanent_allocation flag.
4985 (poplevel): Return early, avoid a seg fault.
4986 * lex.l (NORMAL): Replace this whole state with the predefined
4987 INITIAL state. Force compilation state to global level after
4988 compiler directive error - prevents endless loop on error.
4989 (handle_use_seizefile_directive): Rewrite for readability.
4990 (chill_same_grant_file): Reindent.
4991 Generally handle whitespace differently.
4992 * regression.prpt: Print ten PR numbers per line. The report's
4993 getting too long.
4995 Wed Mar 9 09:58:51 1994 Bill Cox (bill@rtl.cygnus.com)
4997 * decl.c (do_decl): Suppress the string-assignment-condition
4998 error - it was too often seen.
4999 * expr.c (expand_chill_expr): In CONCAT_EXPR, when argument has a
5000 runtime-changing length (as in a slice), get the parent array's
5001 allocation size from its type tree.
5002 * typeck.c (build_chill_slice): Support VARYING arrays. Pass
5003 parent array's static allocation size along in the slice type.
5005 Wed Mar 9 08:54:24 1994 Bill Cox (bill@rtl.cygnus.com)
5007 * lex.l (name_type_signal): Avoid dereferencing a NULL TRE_TYPE.
5009 Tue Mar 8 11:51:10 1994 Bill Cox (bill@rtl.cygnus.com)
5011 * expr.c (build_chill_sizeof): Fix typo in error msg, add
5012 some whitespace.
5013 * lex.l (name_type_signal): Add debug output.
5014 * parse.y (call): Allow EVENTNAME and BUFFERNAME parameters
5015 to a call, so that SIZE () works on them.
5016 * tasking.c (make_process_struct): Force ignore_exprs non-zero
5017 when processing a SEIZEd PROCESS declaration. This prevents
5018 grox-fixed_fields from returning a NULL, and indirectly protects
5019 the chill_integer_type_node tree from corruption.
5021 Mon Mar 7 19:14:05 1994 Bill Cox (bill@rtl.cygnus.com)
5023 * Makefile.in: Use the 'all' target to build the runtime
5024 library and chillrt0.o.

5027 chill.regress.cron: Move to utils subdirectory.
5028 * expr.c (build_chill_function_call): Mark the INOUT
5029 temporary so it doesn't get optimized into a
5030 register. Fixes the execute/inout.ch bug.
5031 * typeck.c (layout_chill_range_type): Restrict it
5032 from complaining about an empty string type's
5033 bounds (0:-1).
5035 Mon Mar 7 09:06:39 1994 Bill Cox (bill@rtl.cygnus.com)
5037 * Makefile.in (compiler): Restore this target.
5038 (OBJS, BC_OBJS): Delete unused variables.
5039 Add $(FLAGS_TO_PASS) to sub-make invocations.
5040 * ch_decomment.l, ch_makedepend, chill.patches, printf.c,

5045 * except.c (finish_handler_array): When computing address of
5046 the array ex_decl, don't call build_array_ref.
5048 Sat Mar 5 17:43:36 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
5050 * loop.c (declare_temps): Force powerset temp to memory.

5060 * decl.c, grant.c: Fix -Wall violations.
5061 * parse.y: Fix format of %type directives.

5065 * Makefile.in: Update version number.
5066 * expr.c: Fix a comment.
5067 * inout.c (build_chill_writetext): Add handling of a REAL.
5068 * lex.l (INITIAL): Remove all code to discard 'header lines'.
5069 no longer needed.
5070 * parse.y (optheader): Remove - it's obsolete, as is the
5071 HEADEREL token definition.
5073 Fri Mar 4 09:41:18 1994 Bill Cox (bill@rtl.cygnus.com)
5075 * addtest: Fix suffix removal when suffix is .c186.
5076 * regression.sh: Allow for underscores on PR filenames.
5077 * typeck.c: Check in the rewrite mentioned earlier.
5079 Thu Mar 3 09:42:10 1994 Wilfried Moser (fs_moser at rcsw1h)

5094 (convert_for_assignment): Check whether to generate runtime
5095 range-checking code. Handle reference_type in convert call.
5096 (chill_expand_assignment): Produce an INDIRECT_REF for a

5131 adjust_return_value function.
5132 * ch-tree.h (CH_RETURNS_LOC): Add new flag for function types.
5133 New parameter for push_extern_function and start_chill_function.
5134 * decl.c (push_extern_function, start_chill_function): New parameter
5135 to say whether return value is a LOC.

5159 * Makefile.in (check): Force the building of ../gcov and
5160 ../xgcc before testing. Move the printf dependency here
5161 since we don't need it until we're testing.
5162 * addtest: Strip suffix from each input filename.
5163 * decl.c (do_decl): Correct error checking. Call
5164 string_assignment_condition for some of it.
5165 * tasking.c (build_gen_inst): Add ability to pass an integer
5166 for either the process ID or the copy number. If a number
5167 is passed, range-check it against the CHILL unsigned type
5168 limits.
5169 (build_buffer_descriptor): Add draft code to check the buffer
5170 name for correctness.
5172 Wed Feb 23 15:07:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
5174 New cleaner solution to the following problem:
5175 Chill allows an action to be followed by an ON-handler.
5176 But we don't know if an action has a handler until we've parsed
5177 its end, yet we want to generate extra code to set up an
5178 exception handling contour only if needed. The old solution
5179 would generate code for the action into an rtl sequence, and then
5180 splice in the exception-setup code if we later found we needed it.
5181 This has a few problems (for example it confuses the management
5182 of stack temporaries), and is ugly. Now that the compiler is 2-pass
5183 we have a cleaner solution: In pass 1, we remember which actions
5184 were followed by ON-handlers. In pass 2, we use this information
5185 to generate appropriate code before an action.
5186 * except.c (push_handler, pop_handler): In pass 1, set up data
5187 structures (global_handler_list) to remember if an action has an
5188 ON-handler. In pass 2, digest this information, and setup
5189 handler if needed.
5190 * except.c, actions.h (pop_handler): Take an extra int arg.
5191 * except.c (emit_setup_handler): New function, with code (moved

5193 * except.c (except_init_pass_2): New function.
5194 * parse.y (pass1_2): Call except_init_pass_2 before pass 2.

5196 * parse.y: Invoke POP_UNUSED_ON_CONTEXT and POP_USED_ON_CONTEXT
5197 in pass 1 as well as pass 2.
5198 * parse.y (BEGIN ... END): Re-arrange logic to avoid block_stack
5199 (local to ../stmt.c) getting out of sync.
5200 * actions.c (push_action): Don't need to emit a NOP,
5201 now that we're no longer moving sequences around.
5202 * actions.c (push_action): Call push_handler even in pass one.
5204 Wed Feb 23 11:06:14 1994 Bill Cox (bill@rtl.cygnus.com)

5821 on constructor_stack, to allow for nested initializers.
5822 * ch-convert.c (digest_constructor): If we need a varying
5823 array, and have a constructor (for the array elements),
5824 make sure to use convert so that the constructor gets
5825 wrapped in an implicit record constructor.
5826 * ch-decl.c (do_decl): If there is no initializer for a
5827 varying array (or bitstring), create default constructor.
5829 * ch-expr.c (build_chill_lower): Fix thinko for ARRAY_TYPE.

5834 which does the actual work for build_chill_array_ref (which
5835 now just loops over an argument list).

5837 instead of build_chill_array_ref where appropriate.
5838 * ch-actions.c, ch-expr.c, ch-typeck.c: Make operand 1 of a
5839 VARY_ARRAY_REF is a single index, not an index list.
5841 * ch-grant.c (__init_list): Renamed to _ch_init_list, to
5842 avoid a conflict on the Alpha.
5844 Wed Jan 12 10:19:35 1994 Bill Cox (bill@rtl.cygnus.com)
5846 * ch-lex.l (WS): Add BS, VT and CR to definition of

5854 * ch-expr.c (build_chill_addr_expr): Add error message.
5855 * ch-grant.c (chill_finish_module_code): Avoid abort by

5868 to work around a bug in /usr/ucb/cc on SunOS4.
5870 Mon Jan 10 18:29:36 1994 Bill Cox (bill@rtl.cygnus.com)
5872 * ch-actions.c (chill_convert_for_assignment): Avoid seg fault.
5873 * ch-expr.c (expand_packed_set): Add new parameter to pass
5874 set's minimum ordinal value. Fix loop invariant problem.
5875 (fold_set_expr): Change to add new parameter to
5876 expand_packed_set call.

5893 Also, fix some bugs for bitstrings (with ranges).
5895 (Patches from Tiemann.)
5896 * ch-convert.c (convert1): New function to force TREE_TYPE.
5897 (convert): Use convert1 where appropriate.
5898 * ch-typeck.c: Formatting change.
5899 * ch-parse.y (build_chill_constructor): Fix thinko.
5901 * ch-expr.c (varying_to_slice): If array is not referable,
5902 call save_expr on it, rather than stabilize_reference.
5903 * ch-satisfy.c (safe_satify_decl, for CONST_DECL):
5904 Don't force value to value class if mode is not explicitly
5905 specified. Also, make sure convert etc is only done once.
5907 Sat Jan 8 16:37:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
5909 * ch-decl.c (build_chill_function_type): Don't call
5910 build_function_type, because it does hash canonicalization,
5911 which once in a while looses badly.
5912 * tree.c (build_function_type): Remove no-longer-needed test
5913 for doing_chill_thang.
5915 * ch-tree.h (CH_DERIVED_FLAG): New flag.

5930 * ch-expr.c (finish_chill_binary_op): Use convert_to_class.
5931 * ch-satisfy.c (safe_satisfy_decl): For CONST_DECL, make sure
5932 DECL_INITIAL gets set to result of convert.
5933 Also, clear CH_DERIVED_FLAG for SYN value.
5934 * expr.c (store_constructor): If a [power]set is exactly one
5935 word long, use single-word move.
5937 Sat Jan 8 08:38:29 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5939 * c-typeck.c (chill_initializer_constant_valid_p): Fix typo.
5941 Wed Jan 5 05:18:46 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5943 * ch-typeck.c (build_chill_slice_with_length): Test that ARRAY is of
5944 ARRAY_TYPE before assuming so. Also, subtract 1 from LENGTH in
5945 computation of SLICE_END.
5947 * ch-typeck.c (chill_location): Treat CONSTRUCTORs like STRING_CSTs.
5949 * ch-expr.c (build_chill_indirect_ref): Handle MODE == NULL_TREE.
5951 * ch-expr.c (fold_set_expr): Handle OP1 == NULL_TREE (which happens
5952 for unary set operations).
5954 * ch-expr.c (build_chill_array_expr): Take new argument FORCE. All
5955 callers changed. All callers changed.
5957 * ch-convert.c (digest_structure_tuple): Handle SELECTED_VARIANT
5958 being NULL_TREE until we've started walking the list of values via
5959 the loop over VARIANTs.
5961 * ch-parse.y (build_chill_constructor): If we see an IDENTIFIER_NODE,
5962 treat it as an enum value (and hence constant). Also, only set
5963 TREE_STATIC if the constructor is indeed constant.
5964 * c-typeck.c (chill_initializer_constant_valid_p): If we see a
5965 VAR_DECL, test the TREE_CONSTANT field of the DECL_INITIAL, don't
5966 recurse on the DECL_INITIAL.
5968 Wed Jan 5 01:24:50 1994 Bill Cox (bill@cygnus.com)
5970 * Makefile.in: Add CHILL to LANGUAGES variable.
5971 * ch-actions.c (check_range): Call build_binary_op instead of
5972 fold, build to get the common types chosen.
5973 (cond_range_exception, cond_overflow_exception,
5974 cond_type_range_exception): Delete, obsolete.
5975 (chill_convert_for_assignment): Enable this, get particular
5976 about when to generate rangecheck code.

5978 perform chill_convert_for_assignment on actual parameters.
5979 (build_chill_addr_expr): Correct compiler warning.
5980 * ch-loop.c (build_chill_iterator): Add runtime check for
5981 negative loop step expression.
5982 * ch-tree.h: Add prototype.
5983 * ch-typeck.c (chill_max_vary_array_ref): Correct misunderstanding.
5984 A varying array's length field counts the NUMBER of active array
5985 array entries, not the byte-length of them.
5987 Tue Jan 4 17:57:39 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5989 * ch-decl.c (do_decl): Call `suspend_momenary' if the
5990 converted constructor must live on the permanent_obstack.
5991 * ch-convert.c (convert): When building a new SET_TYPE
5992 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5993 * c-typeck.c (chill_initializer_constant_valid_p): Handle VAR_DECLs.
5995 * ch-typeck.c (chill_location): CONSTRUCTORS that are static
5996 are locations.

5998 on permanent_obstack if necessary.
6000 * ch-convert.c (digest_structure_tuple): When building a new SET_TYPE
6001 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.

6004 the patch below helped to mess up.
6006 * ch-expr.c (build_chill_arrow_expr): Call `mark_addressable'.
6007 (build_chill_addr_expr): Take new argument ERRORMSG.
6008 All callers changed. Also, call `build_chill_addr_expr' where
6009 we used to call `build1 (ADDR_EXPR, ptr_type_node, ...)' since
6010 that now calls `mark_addressable' automagically.
6012 * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.
6013 This is needed because variables may appear in initialization
6014 statements, and their DECL_INITIALs are their values at
6015 initialization time.
6016 * ch-convert.c (digest_structure_tuple,digest_constructor): Changed
6017 to handle VAR_DECLs as initializers.
6019 * ch-convert.c (digest_structure_tuple): Copy elements of INITS so
6020 they aren't destroyed for later use.

6025 parameter for varying_array_ref calculations.
6026 (build_chill_indirect_ref): Prevent seg fault due to syntax error.
6027 * ch-typeck.c (build_chill_slice_with_range): Correct issuance
6028 of bogus error in votrics.
6029 (build_chill_slice_with_length): Change for debug tracability.
6031 Tue Jan 4 02:43:37 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6033 * ch-convert.c (digest_structure_tuple): Fix phasing problem in
6034 handling variant record initializers.
6035 (various places): Change `pop_init_level' calls to match
6036 `push_init_level' wrt implicit variable.
6038 * ch-typeck.c (build_chill_slice): Convert the dynamic max index to
6039 `integer_type_node' before using it in comparisons. FIXME: should
6040 this be done in `chill_max_vary_array_index' by default?
6042 Tue Jan 4 00:24:14 1994 Bill Cox (bill@cygnus.com)
6044 * ch-actions.c: Fix comments.
6045 * ch-parse.y: Define caseaction_flag.
6046 (caseaction): Create new caseaction_flag node at the start,
6047 then free it at the end. Check it before the ELSE code.
6048 (expanded_case_label): Check the flag here. If set in either
6049 place, generate a jump to the end of the case.
6050 * ch-typeck.c (build_chill_slice_with_length,
6051 build_chill_slice_with_range): Add lots of compile-time
6052 parameter range checking.
6054 Mon Jan 3 21:49:04 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6056 * ch-convert.c (digest_structure_tuple): Call `push_init_level' with
6057 implicit==0 everywhere, not 1.
6058 (digest_constructor): Ditto.
6060 * ch-actions.c (check_range): Permit limits to be NULL_TREE.
6061 Also, hack out some dead code.
6062 * ch-typeck.c (build_chill_slice): Check varying and non-varying
6063 slice constructs for range failures.
6064 (build_chill_slice_with_range): Reindented, but not changed.
6066 * ch-typeck.c (chill_max_vary_array_index): New function.
6067 * ch-expr.c (chill_expand_expr): Call it.
6069 * ch-decl.c (var_data_id, var_length_id): New variables.
6070 (init_decl_processing): Initialize them. All calls to
6071 get_identifier (VAR_LENGTH or VAR_DATA) are now replaced
6072 by references to these variables. This simplifies the code
6073 w/o obscuring anything.
6075 Mon Jan 3 21:24:44 1994 Bill Cox (bill@cygnus.com)
6077 * c-typeck.c: Fix comment.
6078 * ch-actions.c (chill_expand_assignment): Error assigning to
6079 READONLY location. (PR_3903) Pass filename, linenumber
6080 to setbitpowerset runtime routine.
6081 * ch-decl.c (init_decl_processing): Add filename, linenumber
6082 parameters to setbitpowerset prototype.
6083 * ch-expr.c (build_chill_function_call): Error when passing a
6084 READonly location as a LOC or INOUT parameter.
6085 * ch-parse.y (mode): Correct code marking type as readonly.
6087 Mon Jan 3 19:03:55 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6089 * ch-actions.c (chill_expand_assignment): Disable code that defeats
6090 building varying array references.
6091 * ch-expr.c (chill_expand_expr): Add rangecheck code to
6092 VARY_ARRAY_REF case.
6093 * ch-typeck.c (build_chill_array_ref): Don't call an `expand_'
6094 function (in this case, `validate_varying_array_ref') when we're
6095 doing a `build_' operation.
6097 * ch-typeck.c (validate_varying_array_ref): Simplify interface
6098 since INDEX parameter can never meaningfully be an INDEXLIST.
6099 * ch-actions.c (expand_varying_length_assignment): Caller changed.
6101 Mon Jan 3 07:29:45 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6103 * ch-typeck.c (build_chill_cast): Set TREE_CONSTANT on NOP_EXPRs.
6104 * ch-convert.c (digest_structure_tuple): Switch to permanent_obstack
6105 if we need to build a CONSTRUCTOR for a SET_TYPE initializer.
6106 (digest_structure_tuple): If TREE_VALUE (VALUE) == NULL_TREE, don't
6107 call CH_COMPATIBLE or try to convert it to TREE_TYPE (FIELD). This
6108 can happen when constructors are output incrementally.
6109 * c-typeck.c (initializer_constant_valid_p): Handle SET_TYPEs.
6110 * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
6111 CONSTRUCTORS.
6113 Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6115 * ch-convert (digest_structure_tuple): Handle SET_TYPEs. Also, call
6116 `convert' so we can handle INSTANCE types (and other anomolies)
6117 correctly.
6119 * ch-convert.c (digest_structure_tuple): Fixed variant
6120 structure initialization. Also fixed a typo (TYPE_NAME
6121 was being used on a FIELD_DECL instead of DECL_NAME).
6122 * c-typeck.c (initializer_constant_valid_p): Pass missing
6123 ENDTYPE argument on recursive call.
6124 (set_init_field): New function, needed by ch-convert.c change above.
6126 * ch-decl.c (layout_chill_variants): Added a FIXME next to an
6127 almost certain typo.
6129 * ch-expr.c (build_chill_arrow_expr): Call `build1' and set
6130 TREE_CONSTANT for static references.
6131 * ch-except.c (chill_start_on): Change calls to
6132 `build_unary_op' (which is C-specific) to `build_chill_arrow_expr'
6133 which has CHILL semantics.
6134 * ch-convert.c (convert): Ditto (albeit in some disabled code).
6136 Sat Jan 1 21:26:43 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6138 * ch-satisfy.c (safe_satisfy_decl): Reorder conditional test of
6139 TREE_CODE of DECL in case it's altered by actions in the switch.
6141 * ch-satisfy.c (satisfy): Undo abort added earlier on 1 Jan. CVS log
6142 mentions where to find code that triggers this case.
6144 * ch-actions.c (adjust_parm_or_field): Handle CONSTRUCTORS here as
6145 well.
6147 * ch-convert.c (digest_structure_tuple): Push to permanent_obstack if
6148 we're dealing with a CONSTRUCTOR that is TREE_PERMANENT.
6149 (digest_constructor): Ditto.
6151 Sat Jan 1 10:29:19 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6153 * ch-parse.y (handleraction,resultaction,assignaction,call): Modified
6154 so that CONSTRUCTORS are properly handled before being used.
6156 * ch-convert.c (chill_start_init): New function. All callers to
6157 `start_init' changed to call this function instead.
6158 (digest_struct_tuple): Defend against initialization machinery
6159 mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
6160 IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
6161 needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
6162 can be refered to throughout the compilation unit. Also remove an
6163 extraneous call to `process_init_element' erroneously added to the
6164 variant record sub-loop.
6165 (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
6166 CONSTRUCTORS of SET_TYPE.
6167 * ch-parse.y (build_chill_constructor): Refix typo. Also set
6168 TREE_STATIC if at top level.
6170 * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
6171 TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
6172 should have been called.
6174 * ch-convert.c (digest_struct_tuple): Restore code which tracks
6175 field initializations so that the compiler can deduce what variant
6176 initializations to assume.
6178 * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
6179 when we push into a scope that has a DECL with a CONSTRUCTOR as its
6180 DECL_INIT.
6182 * ch-parse.y (build_chill_constructor): Change the name of the
6183 parameter to something more meaningful. Fix typo. Also, handle case
6184 where element is an untyped CONSTRUCTOR.
6186 * ch-except.c (finish_handler_array): Set TREE_CONSTANT on
6187 constant ADDR_EXPRs.
6188 (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT
6189 on JBUF_REF (instead of calling `build1' which does not).
6191 * ch-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
6193 * ch-typeck.c (chill_expand_tuple): Deleted.
6194 * ch-parse.y (primval rule): Don't call `chill_expand_tuple';
6195 instead, use initialization machinery for CONSTRUCTORS that
6196 come through here.
6197 * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
6198 that are created here.
6199 * ch-satisfy (satisfy): Abort in case we would have called
6200 chill_expand_tuple. FIXME: some other code is needed here,
6201 but I don't know what yet.
6203 * ch-parse.y (build_chill_constructor): New function to
6204 propagate TREE_CONSTANT bits to CONSTRUCTORS.
6205 (untyped_expr rule): Use it.
6206 (primval rule): Use it.
6208 * ch-decl.c (do_decl): Call `finish_init'.
6209 * ch-convert.c (convert): If we spontaneously create a CONSTRUCTOR in
6210 this function, make sure the initialization machinery is set up.
6212 * ch-convert.c (digest_structure_tuple, digest_constructor): Add
6213 missing prototypes.
6215 Fri Dec 31 11:31:01 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6217 * ch-grant.c (chill_finish_module_code): Mark ADDR_EXPR built by hand
6218 as being TREE_CONSTANT. Otherwise it gets bounded by the initializer
6219 code.
6221 * ch-decl.c (do_decl): Change in CONSTRUCTOR handling due to...
6222 * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
6223 rewritten to work with GCC's initialization code. The basic change
6224 was to keep the initializers in sync with the initialization
6225 machinery that `process_init_element' imposes. Both of these
6226 functions now return `void'.
6227 * ch-convert.c (convert): Changed calls to `digest_...' functions.
6229 FIXME: the code handling UNION_TYPE (and variant records) has not
6230 been tested yet.
6232 Fri Dec 31 15:32:56 1993 Bill Cox (bill@rtl.cygnus.com)
6234 * ch-lex.l (convert_number): Output the converted number if
6235 yydebug is enabled.
6236 * ch-parse.y (signaldef): Set ignore_exprs correctly for a
6237 SIGNAL declaration.
6239 Fri Dec 31 13:17:48 1993 Bill Cox (bill@cygnus.com)
6241 * ch-parse.y: Cleanup handling of RETURN actions, to distinguish
6242 a RETURN without a value (which cannot have an exception
6243 handler) from a RETURN with a value (which can). Eliminate
6244 some shift/reduce and reduce/reduce conflicts.
6246 Thu Dec 30 17:42:32 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6248 * ch-inout.c (build_chill_writetext): Deal with 2 cases where
6249 types returned from `type_for_size' are not expected. FIXME.
6250 * ch-decl.c (init_decl_processing): Mark `char_type_node' unsigned.
6251 This is required when range checking is enabled.
6253 Thu Dec 30 14:28:25 1993 Bill Cox (bill@rtl.cygnus.com)
6255 DELAY CASE works now.
6256 * ch-decl.c (init_decl_processing): Move rest of tasking-related
6257 initialization into tasking_init().
6258 * ch-parse.y (delaycaseaction): Pervasive additions/corrections.
6259 (optsetprio): New non-terminal.
6260 * ch-tasking.c (get_task_name): Delete, obsolete.
6261 (build_instance_type): build pointer to instance type also.
6262 (build_receive_case_start): Cleanup per -Wall messages.
6263 (build_receive_case_label): Move between start and end functions.
6264 (build_delay_case_start): Pass SET name and priority also.
6265 Generally update to correct functioning.
6266 (build_delay_case_label): Move between start and end fucntions,
6267 correct its functioning.
6268 (build_delay_case_end): Correct the code.
6269 (tasking_init): Lots of tasking-related code moved here from
6270 init_decl_processing.
6271 * ch-tree.h: Update, add prototypes.
6273 Wed Dec 29 10:13:10 1993 Bill Cox (bill@rtl.cygnus.com)
6275 * ch-expr.c (build_chill_indirect_ref): Revert change which
6276 failed full regression testing.
6277 * ch-lex.l (name_type_signal): Add debug output.
6278 * ch-parse.y (structured_variable): Add a debug variable.
6280 Wed Dec 29 02:05:51 1993 Bill Cox (bill@rtl.cygnus.com)
6282 * ch-decl.c (get_next_decl): Revert change which failed full
6283 regression testing.
6285 Tue Dec 28 18:20:14 1993 Bill Cox (bill@rtl.cygnus.com)
6287 DELAY actions work now.
6288 * ch-decl.c: Correct spelling in comments.
6289 (get_next_decl): NULL out the decl's TREE_CHAIN before returning
6290 it, to prevent accidental access to the remembered_decls.
6291 (init_decl_processing): Add wait_event to runtime functions.
6292 * ch-expr.c (build_chill_indirect_ref): Prevent a syntax error from
6293 becoming a seg fault.
6294 * ch-grant.c: Correct a comment.
6295 * ch-loop.c: Delete/correct comments.
6296 * ch-parse.y (delaycaseaction): Add push/poplevel calls. Turn 'sorry'
6297 into rough draft of actual code.
6298 (delayaction): Don't make a new scope here, use get_unique_identifier
6299 instead.
6300 (locdec): process event decls here, too.
6301 (mode): Add code to forbid READonly EVENT and BUFFER decls. Delete
6302 code which required EVENTs and BUFFERs to be declared at global scope.
6303 (simple_name_string): Add an EVENTNAME.
6304 * ch-satisfy.c (safe_satisfy_decl): Prevent a syntax error from
6305 becoming a seg fault.
6306 * ch-tasking.c (tasking_setup): Add the event queue's max. length
6307 as the 'entry_point' parameter in the list.
6308 (build_receive_case_start, build_receive_case_label): Defer
6309 calling runtime routine until we know whether we have a signal
6310 or a buffer to wait for.
6311 (build_delay_case_start, build_delay_case_end,
6312 build_delay_case_label, build_delay_action,
6313 process_event_decls): Added functions.
6314 * ch-typeck.c (chill_similar): Allow all integers of differing
6315 precisions to be similar.
6317 Thu Dec 23 18:00:40 1993 Bill Cox (bill@rtl.cygnus.com)
6319 * gcc.c (CHILL SPECS): Delete references to -M -MM -MD -MMD
6320 options. Delete C-specific defines. Disable piping from
6321 pre-processor to cc1chill (even if -pipe is specified), since cc1chill
6322 rewinds its input for its second pass. Piping still works
6323 from cc1chill to as.
6325 Thu Dec 23 12:31:55 1993 Bill Cox (bill@rtl.cygnus.com)
6327 * ch-tasking.c (decl_tasking_code_variable): Assure that the
6328 tasking_code variable is allocated on the permanent obstack.
6329 (tasking_setup): Lots of changes - handle EVENT/BUFFER max.
6330 queue length (passed as the entry_point parameter).
6331 Other changes to variable names to increase 'self-documentation'
6332 the only kind GNU CHILL will get, for a while..
6334 Wed Dec 22 10:46:31 1993 Bill Cox (bill@rtl.cygnus.com)
6336 * ch-decl.c (do_seize): Delete - it's unused. Fix comments.
6337 * ch-loop.c (build_chill_iterator): Convert BY expression
6338 so loop involving a SET works. Additional errors generated
6339 for numbered SET expression as start or end expression.
6340 * ch-tree.h: Prototypes for future DELAY functions.
6341 * ch-typeck.c: Standard indentation.
6343 Tue Dec 21 15:30:57 1993 Per Bothner (bothner@kalessin.cygnus.com)

6357 * ch-typeck.c (chill_location): Handle COMPOUND_EXPR properly.
6358 Return 2 if also a referable.
6359 * ch-typeck.c (chill_referable): Re-define to use chill_location.
6360 * ch-tree.h (CH_EQUIVALENT): Re-defined to use chill_equivalent.
6362 * dbxout.c (dbxout_type): Output the type attribute "@S;" to
6363 distinguish a string from a char array, and to distinguish a
6364 bitstring from regulat (power)set. (Needed for Chill.)
6365 * dbxout.c (dbxout_type): Only check for baseclasses in
6366 type.binfo is a vector. (It is used in Chill for tagged unions.)
6368 Fri Dec 17 09:56:07 1993 Bill Cox (bill@rtl.cygnus.com)
6370 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
6371 ch-grant.c, ch-inout.c, ch-loop.c, ch-parse.y,

6385 names in receivecasealternative. Generate error messages
6386 if they're mixed in the same receive case.
6387 (process_buffer_decl): Renamed from build_buffer_decl.
6388 * ch-tree.h: Fix prototypes.
6389 * ch-typeck.c (smash_dummy_type): Handle all four kinds of LANG_TYPE

6399 * ch-loop.c (declare_temps): Calculate end-of-array pointer
6400 using correct type (NOT chill_integer_type).
6401 (begin_chill_loop): Build loop-bypass expression in the
6402 type of the start expression, not in the unsigned type.
6404 Tue Dec 14 15:41:32 1993 Per Bothner (bothner@kalessin.cygnus.com)
6406 * ch-decl.c (push_scope_decls): Re-arrange so that normal
6407 (non-seize) declarations are proclaim_decl'd *before* we
6408 handle the ALIAS_DECLs for seizes. The advantage is
6409 that we can now test for (an approximation) to the
6410 'seizeable' concept, thus avoiding duplicate definitions
6411 when a module has both GRANTs and SEIZE ALL.
6413 * ch-expr.c (build_chill_arrow_expr): No longer re-write
6414 addr-of-conversion to pointer-conversion-of-addr.
6415 * ch-expr.c (build_chill_addr_expr): Re-write to just use

6420 * ch-expr.c (build_chill_addr_expr, build_chill_addr_expr): Don't re-write
6422 * ch-tree.h (chill_root_resulting_mode): Fix typo (missing '_').
6424 * ch-expr.c (finish_chill_binary_op): Use CH_ROOT_RESULTING_MODE
6425 macro (which works on expressions), rather than CH_RESULTING_MODE
6426 (which works on modes, and isn't quite correct).
6427 * ch-tree.h (CH_IS_BOUND_REFERENCE_MODE): New macro.
6428 * ch-typeck.c (chill_read_compatible, chill_compatible):
6429 Use the new macro, which handles NEWMODEs of PTR correctly.
6430 * ch-typeck.c (chill_similar): Return 1 rather than 0 for
6431 dynamic-length array (and string) types (e.g. slices).
6432 * ch-typeck.c (chill_root_mode): If the mode has a Novelty,
6433 just return it as is. (This is still not 100% correct for
6434 NEWMODE of RANGEs, but is close enough.)
6436 Mon Dec 13 16:27:06 1993 Bill Cox (bill@rtl.cygnus.com)
6438 * ch-parse.y (locdec): Avoid passing IDENTIFIER_NODEs to
6439 build_buffer_decl, which then seg faults.

6441 of bufdecl closer to its use.
6443 Mon Dec 13 14:57:55 1993 Bill Cox (bill@rtl.cygnus.com)

6446 to avoid C-specific conversions.
6447 * ch-lex.l (name_type_signal): Rewrite to support BUFFERs and EVENTs.
6448 * ch-parse.y (sendaction): Delete unused statement, use the 'name'
6449 variable.
6450 * ch-tasking.c: Use expand_expr_stmt to avoid C-specific
6451 conversions.
6452 (build_buffer_decl): Save the tasking_code_variable's decl
6453 in the buffer decl tree.
6454 (build_buffer_descriptor): Real, working version.
6456 Mon Dec 13 03:13:36 1993 Bill Cox (bill@rtl.cygnus.com)
6458 * ch-decl.c (print_lang_identifier): Delete code
6459 to print buffer size - it's no longer kept here.
6460 * ch-parse.y (expand_send_buffer): Renamed from
6461 build_send_buffer.
6462 (locdec): Enable building of a buffer decl.
6463 (optresultspec, optresultattr): Add optional

6467 * ch-tree.h (build_send_buffer): Renamed.
6468 * ch-typeck.c (chill_expr_class): Do more complete,
6469 job of classifying expressions. Thanks, Per.

6474 for bitstring constants.
6475 * ch-typeck.c (chill_novelty): The novelty of an (unnamed)
6476 range mode is that of its parent mode; the novelty of READ M
6477 is that of M.
6479 Sat Dec 11 15:14:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
6481 * ch-expr.c (varying_to_slice): Call stabilize_reference
6482 rather than save_expr.
6483 * ch-typeck.c (build_chill_slice): Don't emit warning
6484 if array is a SAVE_EXPR (it is effectively referable).
6485 * ch-typeck.c (chill_root_resulting_mode): Handle
6486 correctly the case that one operand is DERIVED and one is VALUE.
6488 Fri Dec 10 10:00:42 1993 Bill Cox (bill@rtl.cygnus.com)

6515 initial check of read-only-ness.
6516 * ch-typeck.c (build_readonly_type): Fix thinkos.
6518 Wed Dec 8 09:11:46 1993 Bill Cox (bill@rtl.cygnus.com)

6528 * ch-decl.c (start_chill_function): Handle attributes in pass 1,
6529 rather than in pass 2. (It seems to make more sense that way.)
6530 * ch-parse.y (procedureattr): Build attribute list if pass != 2.
6532 * ch-parse.y (mode): Don't call build_readonly_type in pass 2.
6534 Mon Dec 6 14:35:31 1993 Per Bothner (bothner@kalessin.cygnus.com)
6536 This implements NOVELTY and READONLY checking.

6539 * ch-tree.h: New prototypes.
6540 * ch-decl.c (push_modedef): If newmode, lazily "copy" the given mode
6541 immediately (even if it's just a type name), using a LANG_TYPE.
6542 * ch-parse.y (mode): Call build_readonly_type to handle READ.
6543 * ch-decl.c (find_implied_types), ch-grant.c (raw_decode_mode),
6544 ch-satisfy.c (satisfy): Handle a LANG_TYPE.
6545 * ch-decl.c: Remove chill_modes_equiv and other unused junk.
6546 * ch-satisfy.c (safe_satisfy_decl/CONST_DECL): Better
6547 mode compatibility checking for SYN declarations.
6549 * ch-typeck.c (chill_similar): Be more general when checking set
6550 modes for similarity - specifically support calling chill_similar
6551 BEFORE the modes have been satisfied (needed by proclaim_decl).
6552 * ch-decl.c (proclaim_decl): Allow duplicate definitions
6553 of set elements of similar set modes.
6555 * ch-parse.y (caseaction): Call language-independent
6556 expand_start_case rather than c_expand_start_case (which
6557 doesn't allow chars or booleans).
6559 Sat Dec 4 22:16:19 1993 Bill Cox (bill@rtl.cygnus.com)

7054 * ch-decl.c (lookup_name): Recognize WITH_DECLs.
7055 * ch-decl.c (handle_one_level): Variant parts are currently

7142 code variables associated with a process or signal.
7143 * ch-tasking.c (build_gen_inst, build_gen_ptype): Use the decl's
7144 tasking_code_decl pointer, rather than trying to look it up
7145 in the hash table or linked scope list.
7147 Wed Oct 20 09:52:44 1993 Bill Cox (bill@rtl.cygnus.com)
7149 * ch-actions.c (lookup_and_handle_exit): Only output error message

7159 reference by build_start_process.
7160 (print_mode): Use CHILL upper-case convention to print modes.
7161 * ch-lex.l: Must initialize tasking-related trees to NULL at start
7162 of each pass, or we lose the fact that the user did or did not
7163 specify a value for each of them.
7164 * ch-parse.y (check_end_label, action, exceptlist): Only output
7165 error message in pass 1.
7166 (sendaction): Add comments.

7171 passes, using do_decl so we can pass the pass 2 value of the
7172 process_type or signal_code to it. Only update the process_type

7174 parameter to know whether to include an init expression.
7175 (build_process_header): Attach tasking-code_variable to process

7191 generation for decls to not use DECL_ASSEMBLER_NAME.
7192 * ch-decl.c: Set DECL_ASSEMBLER_NAME to DECL_NAME.
7193 This matches C, and allows dbxout to emit proper user-level names.

7196 into the outer scope.

7212 * ch-tree.h: Restore old version.
7213 * ch-expr.c (finish_chill_binary_op): Convert TRUNC_DIV_EXPR
7214 to RDIV_EXPR if an operand is floating. (This functionality

7218 not error_mark_node.
7219 * ch-actions.c (chill_expand_assignment): Allow such borderline

7240 init_list entry.
7242 Sun Oct 17 15:16:54 1993 Bill Cox (bill@cygnus.com)
7244 * ch-convert.c: Move semicolon to separate line - easier to see.
7245 * ch-decl.c (do_decl): Handle untyped_expr initializers by
7246 simply using the variable's declared type - no compatibility
7247 check can be made if the expression has no type.

7249 the loop variable.
7250 (fold_set_expr): Fix two other endless loops by passing
7251 correct parameters to unpack_set_constructor.

7436 * ch-convert.c (digest_constructor): Convert element to element_type.
7437 * ch-parse.y (end_function): Use DECL_ARGUMENTS to check
7438 for parameterless process.
7440 Fri Oct 1 13:57:30 1993 Per Bothner (bothner@kalessin.cygnus.com)
7442 * ch-typeck.c (chill_location): New function.
7443 Based on lvalue_p, but also handle Chill-specific VARY_ARRAY_REF.
7444 * ch-typeck.c, ch-tree.h (CH_LOCATION_P), ch-convert.c: Use
7445 chill_location instead of lvalue_p.
7448 Fri Oct 1 11:28:42 1993 Bill Cox (bill@cygnus.com)
7450 * ch-convert.c (convert): Back out Michael's changes, unintentionally
7451 checked in.
7452 * ch-lex.l (handle_use_seizefile_directive): No longer downcase
7453 seize file names.
7454 * ch-parse.y (sendaction): Fix a couple of seg faults. Comment out
7455 SEND BUFFER processing for now.
7456 * ch-tree.h: Fix comment.
7458 Thu Sep 30 17:00:42 1993 Per Bothner (bothner@kalessin.cygnus.com)
7460 * ch-tree.h (CH_CHARS_ONE_P, CH_BOOLS_ONE_P): New macros,
7461 for recognizing singleton strings.
7462 * ch-tree.h (MARK_AS_STRING_TYPE): New macro.
7463 * ch-tree.c (build_string_type, build_bitstring_type),
7464 ch-convert.c (convert): Use it.
7465 * ch-typeck.c (build_chill_slice): Take length rather than upper
7466 bound. This makes it easier to recognize that A(X UP LENGTH)
7467 really has fixed length. Also, if the argument is string,
7468 mark the slice as a string too. Also, handle varying strings.
7470 * ch-typeck.c (conflate_singleton_strings): New global.
7471 * ch-typeck.c (chill_similar): If conflate_singleton_strings is
7472 set (as it currently is), allow CHARS(1)/BOOLS(1) to be similar
7473 to CHAR/BOOL, as required by the 1984 version of Z.200.
7474 * ch-convert.c (convert_to_char): Convert CHARS(1) to CHAR.
7475 * ch-convert.c ( build_array_type_for_scalar): If input is string,
7476 so is output.
7477 * ch-convert (maybe_turn_scalar_into_arra), ch-tree.h: Removed.
7478 * ch-convert.c (convert): Convert CHAR to CHARS(1).
7480 This fixes 'X // := Y' and is also a general simplification.
7481 * ch-actions.c (chill_expand_assignment): Convert 'LHS OP := RHS'
7482 to 'LHS := LHS OP RHS' (using stabilize_reference on LHS).
7483 Also, call save_expr on RHS if a multiple assignment.
7484 * ch-parse.y (assignaction): Therefore, no longer need to call
7485 stabilize_reference on RHS.
7486 * ch-typeck.c (build_chill_modify_expr), ch-tree.h: Remove
7487 modifycode parameter. Make it the caller's responsibility to
7488 handle <assigning operator>.
7489 * ch-actions.c, ch-decl.c, ch-except.c, ch-expr.c, ch-grant.c,
7490 ch-loop.c: Fix calls to build_chill_modify_expr accordingly.
7492 Wed Sep 29 18:02:55 1993 Per Bothner (bothner@kalessin.cygnus.com)
7494 * ch-lang.c (string_index_type_dummy), ch-tree.h: New variable.
7495 * ch-decl.c (integer_minus_one_node), ch-tree.h: New variable.
7497 * ch-parse.y (arrayindex: modename): Remove useless code.
7498 * ch-satisfy.c (satisfy): Don't gag on string_index_type_dummy,
7499 * ch-tree.c (build_string_type): Pass string_index_type_dummy as
7500 the parent type of the index range.
7501 * ch-typeck.c (layout_chill_range_type): Recognize and handle
7502 string_index_type_dummy - specifically allow an empty range.
7504 Wed Sep 29 13:36:23 1993 1993 Bill Cox (bill@cygnus.com)
7506 * ch-convert.c (convert_to_reference): Check for loc-identity
7507 mismatches correctly (and remove one of those chill_compatible
7508 calls).
7509 * ch-decl.c (decl_tasking_code_var): New function, called from
7510 push_extern_process and push_extern_signal.
7511 * ch-parse.y (end_function): Delete parameter. Check current_function_decl
7512 whether it's actually a process, and whether it has parameters.
7513 Make Michael's change simplifying the pass 2 test, preventing a seg
7514 fault.
7515 (procedure, process): Change calls to end_function, remove
7516 code saving value from build_process_header. Delete redundant chill_
7517 phrases from some function calls.
7518 * ch-tasking.c: Remove some redundant _chill phrases from function
7519 names.
7520 * ch-tree.h: Remove some redundant _chill phrases from function
7521 names. Add the CH_VARYING_ARRAY_TYPE macro, call it from
7522 all relevant places.
7523 * ch-typeck.c: Use the new macro. Cast TREE_CODEs to chill_tree_code.
7525 Wed Sep 29 13:07:43 1993 Per Bothner (bothner@kalessin.cygnus.com)
7527 * ch-convert.c (convert_to_reference): Remove redundancies.
7528 * ch-convert.c (convert): Handle convert_to_reference
7529 with a recursive convert call.
7530 * ch-decl.c (do_decl): Add missing compatibility-checking
7531 of initializer (don't depend on convert).
7533 Tue Sep 28 00:02:25 1993 Per Bothner (bothner@kalessin.cygnus.com)
7535 * ch-tree.h (CH_LOCATION_P): New macro.
7536 * ch-typeck.c (layout_chill_range_type): Fix call to
7537 type_for_size, when figuring out a defaulted parent type.
7538 * ch-expr.c (build_chill_lower, build_chill_sizeof): Check
7539 for TREE_CODE_CLASS != 't' rather than == 'd'.
7540 * ch-expr.c (build_chill_function_call): Use CH_LOCATION_P
7541 to check for location, rather than TYPE_CODE_CLASS == 'd'.
7543 * ch-tree.c (build_string_type): Make 2-pass safe. Also,
7544 change parameter to be length, not index type.
7545 * ch-parse.y (mode2), ch-expr.c (build_concat_expr), ch-lex.l
7546 (build_chill_string): Modify callers of build_string_type accordingly.
7547 * ch-lex.l (check_newline): Don't look for # directive inside a
7548 C-style comment.
7549 * ch-grant.c (grant_array_type): Make more robust for char-
7550 and bit-strings (allow non-constant sizes). Change parameters
7551 and return types. (raw_decode_mode): Use grant_array_type
7552 for bitstrings. (otherwise): Fix grant_array_type callers.
7554 Mon Sep 27 16:57:57 1993 Per Bothner (bothner@kalessin.cygnus.com)
7556 Remove changes of Sep 15.
7557 * ch-tree.h (CH_SINGLETON_DOMAIN): Removed.
7558 * ch-typeck.c (chill_similar): Don't allow a singleton
7559 powerset to be similar to its domain.
7560 * ch-convert.c (convert_to_boolean): Don't convert a singleton
7561 SET_TYPE constructor to a Boolean.
7563 * ch-actions.c (chill_expand_assignment): Handle IN_EXPR on
7564 LHS of assignment, which is what we're current (temporarily?) using.
7566 Mon Sep 27 06:01:57 1993 Bill Cox (bill@rtl.cygnus.com)
7568 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
7569 ch-grant.c, ch-inout.c, ch-parse.y, ch-satisfy.c,
7570 ch-tasking.c, ch-tree.c, ch-tree.h, ch-typeck.c:
7571 -Wall cleanup. Add prototypes where missing.
7572 Delete unused variables. Cast uses of tree_codes
7573 to chill_tree_code, which they are.
7575 Sun Sep 26 13:09:57 1993 Bill Cox (bill@rtl.cygnus.com)
7577 * ch-decl.c (do_decl): Save initializer in pass zero
7578 case also.
7579 * ch-lex.l: Fix comments, indentation.
7580 * ch-parse.y: Standardize error messages to use
7581 uppercase for CHILL keywords rather than quoting them.
7582 Suggestion from docs department.
7583 * ch-tasking.c: Pervasive changes to get processes to
7584 compile and START.
7585 * ch-tree.h: Delete prototypes for functions whic
7586 I made static inside ch-tasking.c.
7588 Sun Sep 26 02:40:02 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7590 * ch-lex.l (yywrap): Call `check_newline' in case the file
7591 started with a line directive.
7593 Sat Sep 25 13:54:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
7595 * ch-decl.c: Expand pre-amble comment.
7596 * ch-decl.c (struct scope, push_module): Use new field
7597 tail_chain_module to build child-module list in order.
7598 (Just to make compiler debugging a little less confusing.)
7600 * ch-decl.c (struct scope): New field weak_decls.
7601 * ch-decl.c (find_implied_types): New interface. Now pre-pend
7602 new enum types to a given input list. This makes it easier to
7603 avoid duplicates, which should at least be more efficient.
7604 Also, handle FUNCTION_DECL.
7605 * ch-decl.c (bind_saved_names): Removed. Distribute its
7606 functionality over new functions (push_scope_decls, pop_scope_decls,
7607 build_implied_names, bind_sub_modules). The goal (which seems to
7608 have been more-or-less attained) was to fix weak name handling.
7609 * ch-decl.c (poplevel): Use new function pop_scope_decls.
7611 * ch-tasking.c (build_signal_struct, build_tasking_message_type):
7612 Use build_decl directly, rather than grok_chill_fixedfields
7613 (which depends on ignore_exprs and has more overhead).
7614 * ch-tasking.c (build_signal_struct): Construct the type
7615 only in pass 1.
7616 * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
7617 than build_array_ref (which does C-specific "optimizations").
7618 (Hence move my_build_array_ref up earlier in the file.)
7620 Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7622 * ch-tasking.c: Declare static variable `void_ftype_void'.
7623 (chill_tasking_init): Initialize `void_ftype_void' here.
7624 (build_tasking_struct): Use, don't declare `void_ftype_void'.
7625 (generate_tasking_code_variable): Call `do_decl', not
7626 `decl_temp1' to declare TASKING_CODE_NAME.
7627 (tasking_setup): Drop into 1-pass mode so that all
7628 tasking-related declarations are installed in the global
7629 scope. Use correct CHILL types for initializers (since
7630 ptr_type_node doesn't have the right meaning for CHILL).
7631 Also, call `do_decl' instead of `decl_temp1' for
7632 `init_struct'.
7633 (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
7634 `chill_finish_compile' in sync between passes.
7636 * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
7637 declarations on pass zero. Keep obstacks in sync, and always
7638 call `finish_decl' for pass zero declarations.
7639 (push_chill_extern_function): Keep obstacks in sync, and always
7640 call `finish_decl' for pass zero declarations.
7641 (build_enumerator): Ditto.
7642 (grok_chill_variantdefs): Change PASS test to exclude only
7643 pass one.
7644 (finish_struct): Ditto.
7645 * ch-expr.c (build_chill_component_ref): Ditto.
7646 (build_chill_binary_op): Ditto.
7647 * ch-tree.c (build_powerset_type): Ditto.
7648 (build_bitstring_type): Ditto.
7649 * ch-typeck.c (build_chill_range_type): Ditto.
7650 (build_chill_struct_type): Ditto.
7652 * ch-decl.c (build_chill_exception_decl): Clarify reasons for
7653 extra pushing and popping of obstacks.
7655 * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
7656 on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
7658 * ch-grant.c (chill_finish_compile): Clear out both
7659 MODULE_INIT_LIST and TASKING_LIST if either contains stuff
7660 from pass one.
7662 * ch-parse.y (rccase_label): Add NAME rules so that pass one
7663 works w/o knowing we're parsing a signal. Simplify SIGNALNAME
7664 rules since we only get SIGNALNAME tokens in pass two.
7665 (sendaction): Ditto.
7666 * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
7667 BUFFERNAME on pass two. The grammar now handles this.
7668 * ch-decl.c (lookup_remembered_decl): Deleted.
7670 Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
7672 * ch-decl.c (lookup_remembered_names): Removed. It was being
7673 misused in ch-lex.l.
7674 * ch-lex.l (name_type_signal): Revert last change. Basically,
7675 we cannot use the C typedef/variable name trick in CHILL, due
7676 due to the language's 2-pass nature.
7677 * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
7678 a seg fault.
7679 * ch-tree.h (lookup_remembered_name): Comment out the prototype.
7681 Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7683 * ch-decl.c (do_decl, push_chill_extern_function): Change pass
7684 checks so the pass == 0 case is handled for built-in types.
7685 (push_modedef): Add check for error_mark_node.
7686 (lookup_remembered_decl): New function.
7687 (pushlevel, poplevel) Change pass checks.
7688 (pushdecl): Check type as well for NULL.
7689 (build_enumerator): Handle pass == 0 case.
7690 * ch-lex.l: Use lookup_remembered_decl to get lastiddecl
7691 during pass 1.
7692 * ch-parse.y: Set pass to zero to indicate initial decl processing.
7693 Replace NAME references with SIGNALNAME references.
7694 (startaction): Only check copy number if not ignoring actions.
7695 Always call build_chill_start_process.
7696 (optstartset): Don't lookup the instance name.
7697 * ch-tasking.c (generate_tasking_code_variable): Replace
7698 do_decl call with decl_temp1 call.
7699 (build_chill_start_action): Check for ignore_actions here.
7700 (build_tasking_message_type): Layout the type.
7701 (rc_state_type): New structure to keep nested receive-case
7702 info in.
7703 (build_chill_receive_case_start, build_chill_receive_case_end):
7704 Use the new struct.
7707 Fri Sep 24 04:19:15 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7709 * ch-tasking.c (build_chill_receive_case_start): `namedecl'
7710 should be a _DECL, not an IDENTIFIER_NODE.
7712 Thu Sep 23 18:18:24 1993 Per Bothner (bothner@kalessin.cygnus.com)
7714 * ch-decl.c (find_implied_types): Handle VAR_DECLs.
7716 * ch-decl.c (print_lang_identifier): Print IDENTIFIER_OUTER_VALUE.
7717 * ch-actions.c (chill_expand_result): Allow value-less RETURN.
7718 * ch-expr.c (resolve_component_ref): Recognize error_mark.
7720 * ch-convert.c (digest_constructor): Handle a nested powerset tuple.
7721 * ch-satisfy.c (satisfy): Use return value of layout_chill_range_type.
7722 * ch-typeck.c (chill_similar): Repeatedly get parent modes
7723 of ranges, not just once.
7724 * ch-typeck.c (chill_root_resulting_mode), ch-tree.h: New function.
7725 * ch-typeck.c (layout_chill_rang_type): Re-do type-checking
7726 to follow Blue Book better (check for Compatibility).
7728 * ch-tree.h (CH_ROOT_RESULTING_MODE): New macro.
7729 * ch-lex.l (use_seizefile_name, current_seizefile_name), ch-tree.h:
7730 New variables. The latter replaces in_seizefile.
7732 Changes to store in the new DECL_SEIZEFILE field each seize
7733 ALIAS_DECL the name in the most recent use_seize_file directive.
7734 (This requires that use_seize_file directives written to the
7735 grant file be written before the SEIZEs that need it.)
7736 Allow clashing declarations granted into the global scope
7737 (produce a warning), but remember the seizefile case from
7738 (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
7739 The a SEIZE will select the granted decl that matches its
7740 DECL_SEIZEFILE (in other words: grants from the most recent
7741 use_seize_file will be preferred).
7742 * ch-tree.h (DECL_SEIZEFILE), ch-tree.def: New macro.
7743 * ch-tree.h (global_value, IDENTIFIER_GLOBAL_VALUE): Renamed
7744 to outer_value, IDENTIFIER_OUTER_VALUE.
7745 Changes to cause the use_seize_file directives to be written
7746 out in order as they're seen in source.
7747 * ch-lex.l (files_to_seize, next_file_to_seize, last_file_to_seize):
7748 Changed to have type TREE_LIST of pointer to IDENTIFIER_NODE.
7749 * ch-lex.l (handle_use_seizefile_directive): Modify appropriately.
7750 Don't call grant_use_seizefile.
7751 * ch-lex.l (mark_use_seizefile_written): New function.
7752 * ch-grant.c (decode_decl): Write out use_seize_file directive,
7753 if needed, before writing a seize declarations.
7754 * ch-decl.c (pop_module): Handle decls granted into the global
7755 module specially, setting IDENTIFIER_OUTER_VALUE.
7756 * ch-decl.c (lookup_name_for_seizing): Check IDENTIFIER_OUTER_VALUE.
7758 Thu Sep 23 19:05:37 1993 Bill Cox (bill@cygnus.com)
7760 * ch-decl.c (push_chill_extern_process): Delete unused variables,
7761 declare the process' tasking_code variable as external.
7762 * ch-parse.y (process): Force ignore_exprs to FALSE while parsing
7763 the process header.
7764 * ch-tasking.c (sigdef): Move resetting of quasi_signal from here
7765 to (signaldef).
7766 * ch-tree.h: Add prototype.
7767 * expr.c (store_constructor): Emergency first-aid. Rewrite later.
7769 Thu Sep 23 12:57:53 1993 Per Bothner (bothner@kalessin.cygnus.com)
7771 * ch-expr.c (build_chill_function_call): Move possible call to
7772 chill_start_module_code until we know we're not calling a builtin.
7773 * ch-decl.c (save_expr_under_name): Use pushdecllist,
7774 not proclaim_decl (which provide for popping the decl).
7775 * ch-parse.y (optname): Also allow TYPENAME.
7777 Thu Sep 23 09:18:35 1993 Bill Cox (bill@cygnus.com)
7779 * ch-decl.c (print_lang_decl): Make weak name output more standard.
7780 (print_lang_identifier): Make signal-data flag output more standard.
7781 (push_chill_extern_process): Pass correct arg tree to
7782 push_chill_extern_function.
7783 (push_syn_decls, fixup_unknown_type, chill_modes_equiv):
7784 Standardize function header layouts (Makes the tcov script
7785 work better).
7786 * ch-except.c (chill_finish_on): Standardize function header.
7787 * ch-expr.c (fold_set_or): Standardize function header.
7788 * ch-grant.c (print_proc_tail, print_proc_exceptions): Standardize
7789 function headers.
7790 (decode_constant): Make sure that alpha operators are surrounded
7791 with whitespace.
7792 * ch-parse.y: Spell Z.200 correctly in comments.

7797 * ch-parse.y, ch-decl.c (shadow_record_fields): Use it.
7798 * ch-lex.l (handle_use_seizefile_directive): Don't emit
7799 use_seize_file directive if in_seizefile.
7801 * ch-convert.c (digest_structure_tuple): Fix code that checks
7802 for excess init values.
7803 * ch-decl.c (layout_chill_variants): Move increment of nlabels
7804 inside the proper loop.
7805 * ch-grant.c (print_struct): Add missing loop for tag_list.
7806 (print_struct): Look for variant fields by checking for a
7807 UNION_TYPE, not a NULL name, since we must use a dummy name.
7808 * ch-parse.y (structured_variable): Various fixing.
7809 * ch-decl.c (shadow_record_fields): Rename arg decl -> struct_val.
7811 * ch-satisfy.c (safe_satisfy_decl): Disable copying of modes
7812 for NEWMODE (and hence novelty checking), until we figure out
7813 a better way.
7815 * ch-except.c (finish_handler_array): Use null_pointer_node,
7816 not integer_zero_node (which fails to type-check).
7818 * c-typeck.c (get_constructor_element_type): New function.
7819 * ch-tree.h (CH_NOVELTY_FLAG): Now also used in TYPE_DECLs.
7820 (CH_NOVELTY): Redefined to call new function chill_novelty.
7821 (CH_CLASS_IS_XXX, TYPE_NEWMODE, CH_CLASS_MODE): Removed.
7822 * ch-typeck.c (classify_chill_expr renamed to chill_expr_class):
7823 Take extra output parameter (for M, as in M-value class).
7824 * ch-typeck.c (chill_novelty): New function. (Also de-references.)
7826 * ch-expr.c (resolve_component_ref, build_chill_component_ref):
7827 New functions. Handle 2-pass and variant records.
7828 * ch-parse.y (primval DOT name): Use instead of build_component_ref.
7829 * ch-satisfy.c (satisfy, case COMPONENT_REF):
7830 New case, call resolve_component_ref.
7832 * ch-expr.c (build_generalized_call): Extract single arg from
7833 arg list before calling build_chill_cast.
7835 * ch-parse.y (defining_occurrence_list): New non-terminal.
7836 Use it to replace locnamelist, synnames, and modenames.
7837 * ch-parse.y: Re-write parsing of variant records.
7839 * ch-decl.c (grok_chill_variantdefs): Now return a FIELD_DECL
7840 rather than just its type.
7841 * ch-inout.c (build_chill_io_list_type), ch-parse.y:
7842 Change callers appropriately.
7844 * ch-tree.h (TYPE_TAG_VALUES): Add an extra level of TREE_LIST,
7845 to support multiple tag fields.

7853 digest_structure_tuple when appropriate.
7854 * ch-convert.c (digest_constructor): Re-arrange a bit.

7874 doing the type's layout.
7875 (processpar): Use paramnamelist, but reformat it into a
7876 list of identifiers in pass 2, so a processpar is the same
7877 structure in both passes.

7879 type's layout.
7880 * ch-tasking.c (generate_tasking_code_variable): Call do_decl to

7921 Fri Sep 10 12:23:41 1993 Wilfried Moser (fs_moser@cygnus.com)
7923 * Makefile.in: Change installation of the chill script. gcc will
7924 be called always with the full path. That made problems when

7990 decl_seen_p, processed_decls, allocated, nr_decls): Removed
7991 no-longer-useful functions and variables that used to guard

8037 pass 2.
8038 * ch-grant.c (print_proc_tail): Avoid trying to format

9125 labels aren't lowercased before their time. Add BEGIN
9126 INITIAL before starting pass 2, so the header is

10356 to end of parameter types list.
10358 * ch-grant.c (chill_start_module_code): Make sure module

10460 (finish_chill_enum): Enum constants are marked with
10461 CH_DECL_ENUM so they don't get written to the grantfile.
10462 * ch-tree.h (IDENTIFIER_GRANTED_VALUE): Allow fast seizing.
10463 * ch-lex.l: Re-write to use start states, to avoid calling
10464 yylex() recursively.
10465 * ch-lex.l (compiler_directive); This is now obsolste. FIXME.
10466 * ch-lex.l: Call push_module and pop_module when reading a
10467 seizefile. This creates a pseudo-module.
10468 * ch-parse.y: Clean up handling of empty declarations and
10469 action statements; semicolons are now optional a number of
10470 places.
10471 * ch-parse.y: Remove some bogus tests for "statement
10472 out of sequence" (they're both legal and work).
10473 * varasm.c (mak_function_rtl): Remove kludge that may
10474 not be necessary (and loses anyway).

10497 * ch-grant.c (chill_grant): Test that a declaration is
10498 visible before writing it.
10499 * ch-parse.y (push_module): Make sure to hide declarations

10514 assignment, clean up.
10515 * ch-typeck.c: Add prototype for require_complete_type.

10525 * ch-decl.c (massage_param_node): New function.
10526 It handles the LOC/IN/OUT/INOUT parameter distinction,
10527 as well as calling build_chill_array_parm_type if needed.
10528 * ch-tree.h (massage_param_node): New prototype.
10529 * ch-decl.c (push_parms): Use new massage_param_node().

10534 lower bounds.
10535 * ch-actions.c (build_chill_function_call): If the formal

10539 the pseudo struct type is allocated on the permanent_obstack.
10540 * ch-parse.y (location): Remove thinko.
10541 * ch-actions.c (chill_comptypes): Comment out test for

10564 * ch-typeck.c (my_build_array_ref): Add some more code from
10565 build_array_ref. Change checks, error messages to mention
10566 'discrete types'. I.E. types which don't kiss and tell..

10576 Fri Apr 2 21:55:14 1993 Per Bothner (bothner@rtl.cygnus.com)
10578 Major re-write of New module/seize/grant stuff.
10579 Now, a grantfile is a spec module and contains all the
10580 top-level declarations of the granting module, not just
10581 those that are granted. It also contains explicit grant
10582 statements naming those declared names that are granted.
10583 It also has seize statements and use_seize_file directives
10584 to correctly handle transitive dependencies.
10586 * ch-parse.y: Change to allow multiple modules per source file.
10587 Allow spec modules (including quasi definitions) as well as
10588 regular modules.
10589 Allow spec modules inside normal modules; these behave as if
10590 they were outermost. This violates the Blue Book, but is
10591 needed by the new grantfile mechanism. (A grant file is a
10592 spec module that gets included by the use_seize_file directive.)
10593 * ch-parse.y (struct module *current_module, push_module,
10594 pop_module): Support module nesting (for spec modules only).
10596 * ch-tree.h (struct module): New.
10597 * ch-grant.c (granted_decls): New list of declarations
10598 that have been granted into the outermode pseudo-module.
10599 * ch-grant.c (decode_mode): If the decl has a name,
10600 always write the name, not just if the decl has already
10601 been written. Since we write out all decls, we can assume
10602 it will be written later, and depend on the forward
10603 declaration kludges to catch it.
10604 * ch-grant.c (decode_decl): Don't write out _EXTERN.
10605 Instead write out standard (Blue Book) quasi-definitions.
10606 * ch-grant.c (push_granted): New function.
10607 * ch-grant.c (seize_implied_names): New function. Re-write
10608 how set element names are seized when a set type is seized.
10609 * ch-grant.c (chill_seize): Work by seraching the
10610 granted_decls list and copying the declaration.
10611 * ch-grant.c (chill_grant): Write all declarations
10612 declared in this module. Write GRANT statements for
10613 those granted. seize statements for decls seized from
10614 other modules. Write extra syntax to make a complete
10615 spec module.
10616 * ch-grant.c (grant_use_seizefile): Copy use_seize_file
10617 directives into grant file.
10618 * ch-lex.l (setup_seizefile_read): Call grant_use_seizefile.
10620 * ch-lex.l (struct input_state, current_input_state,
10621 push_input_file, pop_input_file): New (type, variable,
10622 function*2). Used to save and restore state on an input file.
10623 * ch-lex.l: Clean up to handle nested input seizefiles
10624 (needed by new grant/seize mechanism.
10625 * ch-lex.l (skip_to_end_of_directive): New function.
10626 * ch-lex.l (compiler_directive: USE_SEIZE_FILE): Make sure
10627 we skip to the end of the directive *before* we switch
10628 input files.
10629 * ch-lex.l (setup_seizefile_read): Prevent reading the
10630 same seizefile twice (otherwise likely with new grant/seize).
10631 * ch-lex.l: Recognize SPEC. Misc cleanups.
10633 * ch-parse.y: Fixed foreward references of types.
10634 Removed the unknown_type_node crock.
10635 * ch-decl.c: Remove all uses of unknown_type_node.
10636 Check for TYPE_SIZE zero instead.
10637 * ch-decl.c (fixup_unknown_type): Make sure new mode
10638 gets copied into old mode. Merge their variant chains.
10639 * c-decl.c (lookup_name_current_level): Make non-static.
10640 * ch-decl.c (lookup_name_current_level): No longer needed.
10642 * ch-parse.y (call): Allow an implicitly defined function
10643 name following the CALL keyword.
10644 * ch-tree.h (struct lang_identifier): Add implicit_decl,
10645 and make sure order of fields matches c-tree.h.
10647 * ch-actions.c (lang_init, build_allocate_memory_call,
10648 build_allocate_globals_memory_call): Fix names (add initial '_')
10649 and prototypes of _allocate_[global_]memory (2nd param is ref).
10650 Use build_chill_function_call, not build_function_call,
10651 so the reference parameter gets handled.
10652 * ch-actions.c. (lang_init): Make sure boolean_{true,false}_node
10653 have boolean_type_node as their types.
10654 * ch-actions.c (build_chill_lower, build_chill_upper): Fix to
10655 work for arrays with BOOLEAN_TYPE ranges (and simplify some).
10657 * ch-except.c: Make sure an end_label is generated,
10658 and jump to it if there is no exception.
10660 * ch-convert.c (convert_to_reference): Strip off NOP_EXPR casts.
10661 * expr.c (expand_expr): Handle NOP_EXPR as Chill-style casts.
10662 (Need cleaning up and FSF installation!)
10663 * ch-parse.y: If taking the address of a cast, move the
10664 ADDR_EXPR inside the NOP_EXPR.
10666 * ch-typeck.c (my_build_array_ref): Simplified, more suitable
10667 versions of build_array_ref from c-decl.c. (E.g. don't barf
10668 if index type is char or bool.)
10669 * ch-typeck.c (build_chill_array_ref): Use my_build_array-ref.
10671 * ch-typech.c (build_chill_bin_type): New function.
10672 Support BIN(N) range type specification.
10673 * ch-parse.y (mode2), ch-lex.l: Recognize BIN(N).
10675 * ch-tree.h (CH_SIMILAR): Redefine in terms of chill_similar.
10676 * ch-typeck.c (chill_similar): New function. Recognize that
10677 that range types are similar to their parent types.
10679 * ch-tree.h: Declare flag_local_loop_counter.
10680 * ch-loop.c: Whether the loop variable is local to the loop
10681 in now controlled by flag_local_loop_counter, instead of
10682 #ifdef'd on CREATE_SCOPE.
10683 * ch-actions.c (lang_decode_option): Recognize flags
10684 "-f[no-]local-loop-counter".
10685 * toplev.c (lang_options): Add Chill flags -f[no-]local-loop-counter.
10687 * varasm.c (make_function_rtl): Due to problems with forward
10688 references, don't rename nested functions in Chill. (Kudge!)
10690 Sun Mar 28 10:12:45 1993 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10692 * ch-lex.l (push_back, readstring): Fix prototypes.
10694 Fri Mar 26 18:32:15 1993 Bill Cox (bill@rtl.cygnus.com)

10700 Fri Mar 26 13:36:23 1993 Bill Cox (bill@rtl.cygnus.com)
10702 * ch-lex.l (convert_charliteral): Rewrite to avoid bogus error msg.
10703 * ch-parse.y (get_type_of): Add function to deal with possible fwd
10704 declared type name. Call it from lotsa places. Add lotsa checks

10711 * ch-parse.y (action): Add recognition for allocate_memory and
10712 allocate_global_memory system calls.
10713 (mode2): Remove ill-conceived error check that broke REFs to
10714 as-yet-undeclared types. Check for IDENTIFIER_NODE, lookup its
10715 DECL if there, pass TREE_TYPE of decl to build_pointer_type.
10716 (variantfields, varianthack): Clean up.
10717 (variantfield): Check for IDENTIFIER_NODE, lookup its DECL if
10718 there, pass TREE_TYPE of decl to grok_fixedfields.
10719 (labellist): Explicitly assign error_mark_node to signal error.
10720 * ch-typeck.c (chill_compatible): Report FALSE for bad parameters,
10721 rather than seg faulting.
10723 Thu Mar 25 10:35:58 1993 Bill Cox (bill@rtl.cygnus.com)
10725 * ch-actions.c (lang_init): build_function_type for allocate_memory

10727 into ch-typeck.c.
10728 * ch-typeck.c (discrete_type_p): Move here, where it belongs, call it
10729 in build_chill_cast.

10739 avoid abort.
10741 Tue Mar 23 09:03:35 1993 Bill Cox (bill@rtl.cygnus.com)
10743 * ch-actions.c (build_char_array_expr): Just build a type for the

10745 chill_expand_array_assignment can do a better job of
10746 code-generation.
10747 * ch-expr.c (chill_expand_array_assignment): Generate the CONCAT_EXPR
10748 code.

10753 array and its type get on the permanent obstack.
10754 * ch-grant.c (write_grant_file): Don't write the _INIT=name
10755 specifier: It isn't needed, and loses (because of funny
10756 characters in the chill_initializer_name).
10757 * ch-decl.c (push_synmode): Set TYPE_NAME(mode) = syndecl.
10758 * ch-lang.c (finish_chill_enum): Don't allocate a dummy
10759 TYPE_DECL for the enum. I don't think it is needed (?),
10760 and removing it is needed for the change above.

10763 'decl' parameter.
10764 * ch-grant.ch (raw_decode_mode): New function, based on old

10767 raw-decode_mode - but does not call raw_decode_mode if the
10768 type is named and has already been emitted.
10770 Fri Mar 19 11:55:35 1993 Bill Cox (bill@rtl.cygnus.com)
10772 * ch-actions.c: Add prototypes, remove unused variables. Attempt to
10773 continue generating grant file in presence of error (Wilfried's
10774 patch to lang_finish).
10775 * ch-expr.c: Change assign_stack_temp calls so temps get recovered
10776 after each statement. Move convert call into
10777 chill_expand_assignment from ch-parse.y.
10778 * ch-grant.c: Generally re-order, clean up. Include Per's decode_mode
10779 simplification. Include commented-out hack in decode_mode to return
10780 type's name if type SEIZEd or already GRANTed in this file.
10781 * ch-lex.l: Add prototypes.
10782 * ch-parse.y (assignaction): Move convert call into

10796 * ch-parse.y (structured_variable): Return NULL_TREE is invalid WITH
10797 parameter is seen, don't count it in structured_variable_list. Pre-
10798 vents seg fault when only WITH operand is invalid.
10799 * ch-parse.y (label_spec): Correct assignment within IF expression which
10800 was intended to be equality test. Remove unused variables.
10801 * ch-tree.h: Add prototype. Remove unused EXCP_CODE enumeration, and
10802 prototyping editorial comments.
10803 * ch-typeck.c: Disable generation of code to validate array index for
10804 now. Should be done as a call-back from more generic array_ref code.
10805 Clean up parameter checking. Remove unused variables.
10807 Fri Mar 12 11:57:32 1993 Bill Cox (bill@rtl.cygnus.com)

10865 Thu Mar 4 18:05:43 1993 Bill Cox (bill@rtl.cygnus.com)
10867 * ch-actions.c: Define builtin '__nepowerset' and call it - avoid
10868 negating the result of calling __eqpowerset. New function
10869 discrete_type_p().

10908 scope, for CHILL.
10910 Fri Feb 26 07:14:34 1993 Bill Cox (bill@rtl.cygnus.com)

10915 call in build_chill_cause_exception.
10916 * ch-convert.c, ch-expr.c: Use tree_cons to build list's last entry
10917 * ch-loop.c (build_temporary_variable): New function
10918 * ch-process.c: Call build_temporary_variable, spell start_process

10924 * c-decl.c (init_decl_processing): Disable initial creation of C-specific
10925 builtins - they pollute the CHILL name space.
10926 * ch-typeck.c (valid_array_index): Correct upper-bound check.
10927 * expr.c (expand_expr): Use actual library name for __inpowerset
10928 builtin.
10929 * stor-layout.c (variable_size): Disable complaint about variable-
10930 size type or decl at file scope. Perhaps later this s.b. a warning.

10937 * ch-actions.c: Change all builtin functions names to their
10938 actual library names. Change references to boolean_type_node
10939 to references to the TREE_CODE == BOOLEAN_TYPE, to follow the
10940 convention.
10941 build_set_expr: Remove length parameter, call powersetlen() instead.
10942 remove handling of CHAR arrays - they're handled in build_char_array_expr.
10943 Call __eqpowerset to test for equality - we can't use a byte-length -
10944 need bitcount instead.
10945 build_chill_compound_expr, internal_build_compound_expr: Copy from C
10946 version that does stuff we don't want.
10947 build_binary_op: Check for in_size_in_bytes return < 0, indicating
10948 size is changeable at run time. Build two memcpy calls to implement
10949 string concatenation.
10950 powersetlen: Add function.
10951 build_chill_card: Call powersetlen.
10952 build_chill_max_min: Common code for powerset max/min.
10953 build_chill_length: Move VARYING array handling before regular char
10954 array handling.
10955 * ch-expr.c chill_expand_expr: Disable concatenate code - we need to
10956 the VARYING status of the target to do this correctly. Use powersetlen
10957 for the powerset operations, not a byte length.
10958 * ch-loop.c: Make CREATE_SCOPE #define to enable creation of a new scope
10959 for each CHILL loop, as Z.200 requires. Add powerset and error flags
10960 to loop structure. Evaluate user's powerset expression into a temp,
10961 scan it destructively with __ffsetclrpowerset or __flsetclrpowerset
10962 for powerset loop. Only do loop-end assignments if NOT a powerset
10963 loop, which has much less overhead now.
10964 * ch-tree.h: Add prototype for powersetlen.

10977 we are going to return 0.
10979 * ch-convert.c (convert_to_reference): Don't use
10980 TYPE_MAIN_VARIANT, because REFTYPE's type may be a newmode
10981 (which must match the type of the expr).
10983 * ch-grant.c (chill_seize): Don't let a type be copied just
10984 because we are seizing it.

10987 TYPE_MAX_VALUE to integer type.
10989 * ch-loop.c (begin_for_range): Set lp->iter_type based on the
10990 tree type of the bounds.
10991 (build_loop_top): type of GE_EXPR and LE_EXPR is

10993 (for_location): Ditto.
10995 * ch-action.c (build_chill_lower,build_chill_upper): Handle
10996 ENUMERAL_TYPE. Also, handle different kinds of arguments more

11009 comes out error_mark_node, set ERRONEOUS.
11011 * ch-actions.c (build_chill_binary_op_1): If EXP is NULL_TREE,
11012 don't use it.
11014 * ch-action.c (chill_comptypes): Test for structural
11015 equivalence of enums.
11017 * ch-typeck.c (build_chill_array_ref): Convert INDEX to
11018 TYPE_MIN_VALUE of DOMAIN if the types are compatible.
11020 * ch-grant.c (chill_seize): If DECLS is a TYPE_DECL for an
11021 ARRAY_TYPE, seize the domain type if its a set.
11023 Thu Feb 18 20:02:15 1993 Per Bothner (bothner@rtl.cygnus.com)
11025 * c-typeck.c (process_init_constructor): Emit error if some

11082 * ch-convert.c (convert): Slightly more correct conversion
11083 for ARRAY_TYPEs (return as OK if CH_COMPATIBLE).
11084 * ch-expr.c (chill_expand_array_assignment): Invoke
11085 __builtin_memcpy using build_function_call, not directly at
11086 the rtx level (which doesn't work).

11102 * ch-decl.c (grok_chill_variantdefs): Really implement variant
11103 records for CHILL.
11104 * ch-grant.c (get_tag_value): New function.
11105 * ch-grant.c (decode_mode): Grant variant records.
11107 * ch-grant.c (chill_seize): If we seize a set, seize the set
11108 values.

11136 special-case support for a BIT_FIELD_REF in right-hand-side.
11137 * ch-lang.c (finish_chill_enum): Patch up enum elements to
11138 have the correct type (instead of integers, as in C).
11140 * ch-lex.l, ch-parse.y: Add disgusting hack (involving
11141 context-dependent look-ahead) so we can parse exception
11142 handlers correctly.
11143 * c-typeck.c (digest_init): Set output type for SET_TYPEs.
11144 * varasm.c (unpack_set_constructor): Add support for

11181 * ch-lex.l (convert_bitstring), Changed SET_TYPE_CONSTRUCTOR to
11182 take a list of elements which are in the set. This corresponds
11183 better to the tuple input form in Chill (and Pascal).
11184 * varasm.c (unpack_set_constructor, pack_set_constructor):
11185 New functions, to expand SET_TYPE CONSTRUCTORs.
11186 * varasm.c (output_constructor): Use pack_set_constructor
11187 to assemble a SET_TYPE constant from a CONSTRUCTOR.
11189 * ch-grant.c (decode_constant): Better grant for strings,
11190 enumeral, and bitstring constants.
11191 * ch-grant.c: Fixes in seize to avoid duplicates, and emit
11192 things in the correct order.
11193 * c-typeck.c (chill_initializer_constant_valid_p): Kludge
11194 needed to export a static function.
11195 * ch-typeck.c (convert): Avoid needlessly (and lossingly) calling
11196 chill_expand_tuple to convert fix string to varying.
11197 * ch-actions.c (build_chill_binary_op): Promote short
11198 integer operands if needed (otherwise emit routines barf).
11199 * ch-tree.h (SET_WORD_SIZE): New macro.
11200 * ch-parse.y: Fix syntax for RECEIVE CASE.
11201 * ch-parse.y (location): If IDENTIFIER is a CONST_DECL
11202 return its value instead.

11219 redefine the signatures for those runtime routines. Move
11220 empty-set check into runtime.
11221 * ch-expr.c, ch-loop.c, ch-process.c, ch-tree.c, ch-typeck.c: change
11222 most integer_type_node references to chill_integer_type_node.

11226 * ch-except.c: New file. Stuff for exception handling.
11227 * ch-parse.y: Add working exception handling support.
11228 * ch-lex.l, ch-parse.y: Prefer standard type terminology
11229 (BOOLS, CHARS) even though non-standard (BITS, CHAR) is ok.
11230 * ch-grant.c: Fix various problems related to granting
11231 types such as bitsets.
11232 * ch-tree.c (build_bitstring_type): Set TYPE_MIN_VALUE
11233 to distinguish bitstrings from powersets (in the same way
11234 we distinguish char strings from char arrays).
11235 * ch-tree.h: New macro CH_BOOL_TYPE_P.
11236 * ch-tree.h, ch-actions.c (lang_init), ch-grant.c (decode_mode):
11237 Undo kludge where integer_type_node was hardwired to 16 bits.
11238 Make integer_type_node etc have the same size as in cc1.
11239 New types chill_integer_type_node and chill_unsigned_type_node
11240 that correspond to the Chill source types INT and UINT.
11241 For now, these match the C 'short' types, but that should
11242 become a configuration option later,
11244 Tue Feb 9 11:41:25 1993 Bill Cox (bill@rtl.cygnus.com)
11246 * ch-actions.c (build_chill_unary_op): allow NOT of a set.
11248 Tue Feb 9 08:27:18 1993 Bill Cox (bill@rtl.cygnus.com)

11251 too many/few actual parameters (and avoid seg fault).
11252 * ch-decl.c (do_decls): code cleanup for readability.
11253 * ch-loop.c (begin_chill_loop, end_chill_loop): remove
11254 emit_nop() calls - they now (since exceptions) cause seg faults.
11255 Make derogation on poor CHILL compiler non-specific.
11256 * ch-parse.y (mode2): enable VARYING keyword in CHAR(expr).
11257 * ch-tree.h: remove prototypes added to c-tree.h.
11258 * ch-typeck.c (build_chill_array_ref): correct getting domain
11259 subtree for a PARM_DECL. Subscripting a SET_TYPE is turned into
11260 an IN_EXPR.
11262 Sun Feb 7 18:20:49 1993 Bill Cox (bill@rtl.cygnus.com)
11264 * ch-tree.def: add a new tree type - just for varying array
11265 references. We were using ARRAY_REF, but the underlying C
11266 code also generates that one.
11267 * ch-convert.c, ch-expr.c, ch-typeck.c: use the new tree type.
11269 Sun Feb 7 17:33:17 1993 Bill Cox (bill@rtl.cygnus.com)
11271 * ch-convert.c: test given type against type of expr before
11272 calling chill_expand_tuple. We were getting lots of spurious
11273 calls...

11277 * cccp.c: Merge in various Chill-specific changes.
11278 * gcc.c (default_compilers array): Pass -lang-chill
11279 to cpp, not -lang-ch.
11281 Fri Jan 29 17:18:22 1993 Per Bothner (bothner@rtl.cygnus.com)
11283 * Makefile.in (install-libchill, install-librmt): Removed.
11284 * ch-actions.c (build_chill_exception_decl): Change decl
11285 to initialized char array, rather than uninitialized common.
11286 (Simplifies extracting string name of exception.)
11287 * ch-actions.c: Adjust interface to cause_exception accordingly.
11288 * ch-typeck.c (build_chill_array_ref): Cause rangefail if
11289 index > limit, not >= limit.
11291 * ch-actions.c (build_chill_function_call): Rename misleading
11292 formal parameter.
11293 * ch-decl.c (do_decls): Allow (again) general initializer exprs.
11294 * ch-parse.y (call): Test for function call needs to test for
11295 FUNCTION_TYPE, not FUNCTION_DECL.
11296 nreverse arg list to build_chill_array_ref.
11297 * ch-typeck.c (build_chill_array_ref): Do recursive call at end
11298 and only if multiple indexes.
11299 * ch-typeck.c: Cleanups.

11731 * ch-hash.h, chill.gperf: cleanup. fewer keywords seen by ch-parse.y.
11733 Sat Jan 2 13:27:49 1993 Per Bothner (bothner@rtl.cygnus.com)
11735 * ch-lex.l (check_newline): Use the orginal versions (derived
11736 from the C code, not the simplified, special-case version).
11737 Also, fix that version of check_newline to not call yylex()
11738 recursively.
11739 * ch-lex.l (yy_input): Call check_newline to handle
11740 newlines and check for # directives.
11741 * ch-lex.l (syntax): Don't recognize #-directives; these
11742 are now handled by check_newline.
11743 * ch-actions.c (lang_init): Call the modified version of
11744 check_newline(). Do this at the *after* we've initialized
11745 standard types, so this can be done while lineno is still 0.
11747 Sat Jan 2 10:57:20 1993 Bill Cox (bill@cygnus.com)
11749 * ch-hash.h, chill.gperf: add remaining reserved words.
11751 Sat Jan 2 09:59:55 1993 Bill Cox (bill@cygnus.com)
11753 * ch-tree.h, ch-parse.y, ch-lex.l: add remaining reserved words,
11754 names for exceptions
11756 Fri Jan 1 12:30:31 1993 Fred Fish (fnf@cygnus.com)
11758 * ch-tree.h (JOINER): Define joiner character the same way
11759 C++ defines it.
11760 * ch-grant.c (chill_start_module_code): Use JOINER character
11761 to implement name mangling for the initializer function name.
11762 Algorithm is designed to be simple, distinct from C++ mangled
11763 symbols, and easy to convert to demangled form.
11765 Thu Dec 31 10:30:51 1992 Bill Cox (bill@rtl.cygnus.com)
11767 * ch-expr.c: make array assignments work with indirect refs.
11768 * ch-actions.c: prepare for array parameter handling.
11769 * ch-loop.c, ch-parse.y, ch-tree.def, ch-typeck.c: clean up.
11771 Thu Dec 31 15:29:20 1992 Per Bothner (bothner@rtl.cygnus.com)
11773 * ch-lex.l (yy_input): Re-write to return more than one
11774 character at a time (execpt when reading seize-files).
11775 Don't increment lineno until we start reading the next line.
11776 This fixes some off-by-one errors in lineno.
11778 Wed Dec 30 16:15:23 1992 Per Bothner (bothner@rtl.cygnus.com)
11780 * ch-convert.c: Assume use of new common.c.
11781 * ch-convert.c (convert_to_reference, convert_from_reference):
11782 New routines, to handle loc-identity declared variables and
11783 LOC parameters (both of which are implemented as references).
11784 * ch-lang.c (convert_to_boolean, convert_to_char): Move to
11785 ch-convert.c, where they would seem to belong.
11786 * ch-convert.c (convert): New function, since we no longer
11787 link in c-convert.c.
11788 * ch-expr.c (chill_expand_assignment): Handle by calling
11789 convert() instead of chill_comptypes().
11790 Also handle the LHS being a reference.
11791 * ch-parse.y: Add a procedure call as an action.
11792 * ch-parse.y (locdec, optlocinit): Move handling of
11793 loc-identity declarations from optlocinit to locdec
11794 - and add working semantics for it.
11795 * ch-parse.y (seizestatement, visibilty_stmt): Simplify.
11796 * ch-parse.y (grantstatement etc): Don't bother making list.
11797 * ch-lex.l: #include <sys/types.h> before <sys/stat.h>.
11799 Wed Dec 30 16:06:55 1992 Bill Cox (bill@rtl.cygnus.com)
11801 * ch-parse.y, ch-expr.c: add support for declaring & assigning
11802 VARYING arrays.
11803 * ch-typeck.c: allow VARYING structures in assign_type_to_expr.
11805 Tue Dec 29 15:28:48 1992 Bill Cox (bill@cygnus.com)
11807 * ch-actions.c: implement expressions of arrays of char,
11808 ( concatenation, relationals ), correct type of code parameters
11809 * ch-expr.c: correct type of code parameters
11811 Tue Dec 29 11:16:19 1992 Bill Cox (bill@cygnus.com)
11813 * ch-decl.c: cleanup.
11814 * ch-parse.y: put emit_line_note() calls in lotsa places,
11815 per Fred's request; be sure that statements get counted also.
11816 * ch-lex.l: standardize function headers.
11818 Tue Dec 29 10:41:56 1992 Fred Fish (fnf@cygnus.com)
11820 * ch-decl.c (start_chill_function): Always return 1, rather
11821 than a random value.
11822 * ch-lex.l (check_newline): Add a version for chill that
11823 just snarfs the right value for main_input_filename out of
11824 the first line of the input file, without disturbing the
11825 lexer state or requiring it's assistance.
11826 * ch-actions.c (lang_init): Call check_newline, like the
11827 other language frontends, to get main_input_filename set
11828 from first line of input file.
11830 Mon Dec 28 18:49:01 1992 Bill Cox (bill@cygnus.com)
11832 * ch-parse.y: clean up conflicts. The remaining one is
11833 harmless.
11835 Mon Dec 28 17:28:40 1992 Bill Cox (bill@cygnus.com)
11837 * ch-parse.y, ch-lex.l, ch-actions.c: add stubs for I/O,
11838 clean up some parser conflicts.
11840 Mon Dec 28 15:00:20 1992 Bill Cox (bill@cygnus.com)
11842 * ch-parse.y, ch-lex.l: add keywords and parsing for most of
11843 CHILL I/O
11845 Sat Dec 26 20:48:23 1992 Fred Fish (fnf@cygnus.com)
11847 * chillrt/chillrt0.c: Oops, SVR4 doesn't need leading '_'
11848 on build_exceptions.
11850 Sat Dec 26 11:00:36 1992 Fred Fish (fnf@cygnus.com)
11852 * ch-grant.c (chill_finish_module_code): Call
11853 assemble_constructor_alias rather than assemble_constructor.
11854 * varasm.c (assemble_constructor_alias): New function,
11855 like assemble_constructor, but also handles the case where
11856 ASM_OUTPUT_CONSTRUCTOR is not defined and GNU ld is not
11857 being used. Emits a symbol table alias name with the correct
11858 prefix for collect to find and add to the __CTOR_LIST__.
11859 * chillrt/chillrt0.c: Build on previous hack that gets
11860 _build_exceptions into the __CTOR_LIST__, to make it work
11861 for both the non GNU-ld case and for the SVR4 case.
11863 Tue Dec 22 18:24:55 1992 Bill Cox (bill@cygnus.com)
11865 * ch-loop.c: clean up location enumeration - one more
11866 pass to do.
11868 Tue Dec 22 16:31:48 1992 Bill Cox (bill@cygnus.com)

11879 ch-loop.c: rough draft of location enumeration
11880 ch-lex.l, ch-expr.c, ch-decl.c: minor cleanup
11881 ch-actions.c: finish making pred() and succ() work.
11883 Mon Dec 21 10:04:35 1992 Bill Cox (bill@cygnus.com)
11885 * ch-actions.c: allow pred(char) and succ(char).
11887 Sun Dec 20 16:04:28 1992 Bill Cox (bill@cygnus.com)
11889 * ch-expr.c, ch-actions.c, ch-parse.y, ch-loop.c,
11890 c-expr.c: make DO WITH work.
11892 Sun Dec 20 12:22:53 1992 Bill Cox (bill@cygnus.com)
11894 * ch-loop.c, ch-actions.c, ch-typeck.c: powerset loops
11895 now work
11897 Sat Dec 19 14:20:23 1992 Per Bothner (bothner@cygnus.com)
11899 * c-typeck.c (process_init_constructor): Add warning if
11900 there is a duplicate default initializer element.
11901 * ch-typeck.c (chill_give_type_to_expr): New function,
11902 to handle coercion of an expression to context-given type,
11903 Takes care of untyped tuples, and case expressions.
11904 * ch-decl.c (do_decls), ch-typeck.c (chill_expand_return,
11905 chill_expand_result), ch-parse.y <assignaction>:
11906 Use chill_give_type_to_expr().
11907 * ch-typeck.c (chill_handle_case_label): New parameter list,
11908 to handle the (new) conventions for <case_label>, including
11909 default elements and ranges.
11910 * ch-parse.y <expanded_case_label>, ch-typeck.c
11911 (expand_case_expr): Use new version of chill_handle_case_label.
11912 * ch-decl.c (push_syndecls): Change parameters: Instead of
11913 TREE_LIST representing a compete <synonym definition statement>,
11914 just pass the parts of a single <synonym definition> as 3
11915 different parameters. Also, use chill_give_type_to_expr(),
11916 to handle untyped tuples in the RHS.
11917 * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct
11918 a tree - just call push_syndecls() on each <synonum_definition>
11919 as we see it.
11920 * ch-parse.y (exprlist_get_single): Remove; no longer needed.
11921 * ch-parse.y: Handle <tuple> without mode name diferently from
11922 <tuple> with mode name. The latter is a <primval> that can be
11923 in most contexts, but if the <mode name> is missing, the <tuple>
11924 is only allowed in certain contexts. Use the new non-terminal
11925 <untyped_expr> to indicate those contexts where untyped tuples
11926 (and case expressions) are valid because the expression gets a
11927 type from its context (such as the RHS of an assignment).
11928 Use chill_give_type_to_expr in those contexts.
11930 Sat Dec 19 14:01:26 1992 Bill Cox (bill@cygnus.com)
11932 * ch-actions.c, ch-loop.c, Makefile.in: looping stuff.
11934 Sat Dec 19 10:16:20 1992 Bill Cox (bill@cygnus.com)
11936 * ch-parse.y: clean up warning messages from byacc. bison
11937 still complains thrice.
11939 Fri Dec 18 12:33:29 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11941 * ch-actions.c (maybe_chill_comptypes): Delete unused
11942 function.
11943 (chill_comptypes): Add new parameter ERRSTR. All callers
11944 changed.
11945 (build_chill_binary_op): Fix indentation to match GNU coding
11946 style.
11948 Fri Dec 18 08:18:13 1992 Bill Cox (bill@rtl.cygnus.com)
11950 * ch-parse.y, ch-expr.c, ch-actions.c, expr.c: major

11960 a default initializer element.
11961 * ch-parse.y: Implement default elements for tuples
11962 (as in '(else):' and '(*):' ).
11964 * ch-parse.y: Previous change to dis-ambiguate case-labels
11965 seems to have allowed getting rid of all of the expr_or_list hair.
11966 * ch-decl.c (do_decls): Undo Tiemann's change to "Handle
11967 initialization of multiple variables by a tuple" - the
11968 idea is bogus.
11970 Wed Dec 16 11:17:53 1992 Bill Cox (bill@cygnus.com)
11972 * ch-parse.y: complete re-write of DO statement handling.
11973 now operational, except WITH is stubbed out. Improved
11974 syntax error message.
11975 * ch-actions.c: DO support: high_domain_value(), low_domain_value ().
11976 * ch-expr.c: fixes to IN_EXPR handling.
11978 Tue Dec 15 17:15:13 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11980 * ch-grant.c: Add casts to alloca return to avoid compiler warning.
11981 * ch-lex.c: Likewise.
11983 * Makefile.in (ch-lex.c): Delete incorrect free declaration added
11984 by flex to avoid compiler error.
11986 Tue Dec 15 08:41:08 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11988 * ch-decl.c (do_decls): Handle initialization of multiple
11989 variables by a tuple.
11991 * ch-decl.c (do_decls,start_chill_function): Make DECL public
11992 if we're doing a GRANT ALL at top level.
11994 * ch-lang.c (build_range_type): Deal with typecast to CHAR in
11995 range expression.
11997 * c-typeck.c (digest_init): SET_TYPE is not a scalar type.
11998 BOOLEAN_TYPE and CHAR_TYPE are scalar types.
12000 Mon Dec 14 14:58:32 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
12002 * ch-lex.l (get_chill_{linenumber,filename}): New functions.
12003 (convert_number): Use LONG_TYPE_NODE instead of INTEGER_TYPE_NODE.
12005 Mon Dec 14 13:36:44 1992 Bill Cox (bill@cygnus.com)
12007 * expr.c: install and test newer Pascal IN_EXPR code,
12008 but don't activate it - it's very verbose.
12010 Mon Dec 14 00:22:49 1992 Fred Fish (fnf@cygnus.com)
12012 * Makefile.in (LANGUAGES): Add chill.

12019 sublibchill.a, ch-parse.o, ch-parse.c ch-*.o, install-libchill,
12020 install-librmt): New targets.
12021 * Makefile.in (install-native): Add install-libchill,
12022 install-librmt.

12028 Sun Dec 13 14:07:32 1992 Bill Cox (bill@cygnus.com)
12030 * ch-actions.c: fix unary operations, modulus ops,
12031 (discovered after extending regression tests).
12033 Sun Dec 13 12:16:32 1992 Bill Cox (bill@cygnus.com)
12035 * resync with Michael and Wilfried
12037 Sun Dec 13 09:11:25 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
12039 * ch-parse.y (output_constant): Fixed some whitespace
12040 problems.
12041 * ch-tree.h: Add declarations for new chill functions that
12042 have been implemented but not (yet) declared.
12044 Sat Dec 12 00:17:23 1992 Per Bothner (bothner@cygnus.com)
12046 * c-typeck.c (process_init_constructor): Warn about duplicate
12047 labels for labelled initializer elements.
12048 * ch-lex.l (various operator tokens, such as "+"): Don't
12049 set yylval.code to a TREE_CODE; this is better done in parser.
12050 * ch-parse.y: Some work with case labels and tuples.
12051 Get literal range as tuple (and case) labels working.
12052 Fix some problems introduced by recent grammar overhaul.
12054 Fri Dec 11 13:28:48 1992 Bill Cox (bill@cygnus.com)
12056 * ch-actions.c, ch-parse.y ch-tree.h ch-expr.c, ch-typeck.c:
12057 got long, real expressions working. We can also call a func-
12058 tion and use its return value.
12060 Thu Dec 10 14:45:17 1992 Per Bothner (bothner@cygnus.com)
12062 * ch-parse.y: Major change to remove or at least identify
12063 parser ambiguities. One result: We now allow actions that
12064 start with '(', as required by teh Blue Book. This does break
12065 some things; look for FIXME for things that need work.
12066 * ch-typeck.c (chill_expand_case_expr): We need an extra
12067 level of looping to (in the future) support <case label
12068 specification>s with more than one <case label list>.
12070 Thu Dec 10 09:21:41 1992 Bill Cox (bill@cygnus.com)
12072 * ch-actions.c, ch-expr.c: Implement string assignments
12073 and relationals.

12081 * ch-parse.y, ch-actions.c, ch-expr.c: redo type checking.
12082 regression test and fix bit arrays and set ops.
12084 Mon Dec 7 14:57:46 1992 Bill Cox (bill@cygnus.com)
12086 * ch-actions.c: implement crude relationals between
12087 non-exotic operands, such as integers.
12089 Mon Dec 7 10:42:35 1992 Bill Cox (bill@cygnus.com)
12091 * ch-actions.c: implement relational, logic operations
12092 on arrays of BOOLs.
12094 Mon Dec 7 08:55:20 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
12096 * ch-actions.c (lang_init): Set LINENO to 1 at beginning to
12097 indicate we are done with initialization.
12099 * ch-decl.c (do_decls): Set TREE_PUBLIC if we are doing a
12100 `grant all'.
12101 (start_chill_function): Ditto.
12103 * ch-lex.c (convert_bitstring): Set TREE_CONSTANT.
12104 (compiler_directive): Don't confuse compiler directives with
12105 equality comparison operators.
12107 * ch-parse.y: Clear CURRENT_LOCNAMELIST after calling do_decls.

12116 relational expressions, including (<, <=, =, /=, >, >=, IN).
12118 Fri Dec 4 13:54:58 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
12120 * tree.def: Move CARD_EXPR and SET_LE_EXPR back down with the other
12121 Pascal-required ones, since C++ no longer needs them. When
12122 Chill's public, a comment can be added to the effect that
12123 SET_LE_EXPR is also used by Chill.
12125 Fri Dec 4 12:05:01 1992 Bill Cox (bill@cygnus.com)
12127 * Restore CARD_EXPR and SET_LE_EXPR to tree.def.

12140 * ch-actions.c, ch-tree.def, ch-parse.y: preparation
12141 for powerset expressions.

12166 (push_newmode,push_synmode): Call `fixup_unknown_type' when we
12167 see a declaration that uses `unknown_type_node'. FIXME.
12169 * ch-grant.c (decode_constant): New function.
12170 (decode_decl): Call `decode_constant' for CONST_DECLs.
12172 * ch-lex.l (char action): Use ridpointers instead of
12173 lookup_name to get "char"'s declaration.
12175 * ch-parse.y: Call `build_lang_decl' instead of `build_decl'
12176 when we need to build a TYPE_DECL.
12178 Tue Dec 2 09:44:05 1992 Bill Cox (bill@cygnus.com)
12180 * ch-typeck.c: clean up a gcc warning with a forward
12181 declaration of build_string_type.
12183 Tue Dec 1 16:51:05 1992 Bill Cox (bill@cygnus.com)
12185 * ch-actions.c: completely remove those builtin calls
12186 that are duplicated in c-decl.c
12188 Tue Dec 1 16:38:51 1992 Fred Fish (fnf@cygnus.com)
12190 * ch-actions.c (lang_init): Ifdef out initializations for
12191 __builtin_abs and __builtin_fabs, since they are duplicates of
12192 initializations in c-decl.c, and trigger spurious warnings.
12194 Tue Dec 1 16:35:18 1992 Bill Cox (bill@cygnus.com)
12196 * ch-parse.y: make size() work with a typename argument.
12198 Tue Dec 1 16:15:56 1992 Bill Cox (bill@cygnus.com)
12200 * ch-parse.y, ch-lex.l, ch-actions.c: add builtin
12201 functions min, max, card.
12203 Tue Dec 1 12:35:56 1992 Bill Cox (bill@cygnus.com)
12205 * ch-lex.l: fix char-type
12207 Tue Dec 1 11:10:56 1992 Bill Cox (bill@cygnus.com)

12212 Tue Dec 1 09:40:49 1992 Fred Fish (fnf@cygnus.com)
12214 * dwarf.h (LANG_CHILL): Add as GNU extension.
12215 * dwarfout.c (output_compile_unit_die): Test language_string and
12216 set LANG_CHILL if appropriate.

12221 * chillrt/Makefile: Adjust for directory renaming.
12223 Mon Nov 30 17:35:33 1992 Fred Fish (fnf@cygnus.com)
12225 * chillsh: New script frontend (ala g++), installed as "chill".
12226 Can't be called "chill.sh" because make tries to cat it into the
12227 "chill" directory. Can't be called just "chill" cause that's
12228 already there as a directory.
12229 * Makefile.in: Add rules to install chillsh as "chill".
12230 * chill/libchill.c: Temporarily ifdef out stuff that wants
12231 to conflict with i486/SVR4 runtime or wants to pull in librmt.a,
12232 which itself causes linkage to fail.
12234 Mon Nov 30 16:28:19 1992 Bill Cox (bill@cygnus.com)
12236 * ch-lex.l: added keywords for TRUNC, ROUND, FLOAT, LFLOAT
12237 conversion routines.
12238 * ch-parse.y: added %tokens for TRUNC, ROUND, FLOAT, LFLOAT.
12239 Added production for SIZE(expr).
12240 * ch-actions.c: Add semantic routine chill_sizeof ().
12242 Mon Nov 30 16:20:40 1992 Per Bothner (bothner@cygnus.com)
12244 * ch-lex.l, ch-parse.y: Translate token PFEIL into English ARROW.
12245 * ch-parse.y (op6): Remove handling of string repetition operator,
12246 until we can figure out a way to parse it correctly.
12247 * ch-parse.y (optmodename): New non-terminal.
12248 * ch-parse.y (tuple): Merge the two variants using optmodename.
12249 * ch-parse.y (location): Add semantic actions for
12250 dereferencing operator ->.
12252 Mon Nov 30 08:01:29 1992 Bill Cox (bill@cygnus.com)
12254 * ch-actions.c: removed compile warning, better code for abs.
12256 * ch-parse.y: add productions for builtin functions succ, pred,
12257 abs, and size. Add %tokens also. Sort %tokens alphabetically.
12259 * ch-lex.l: add parsing for builtin function names, such as abs,
12260 pred, succ, etc. Put flex -a option into Makefile.in, so we can
12261 clean up the lexer soon.
12263 Tue Nov 24 14:18:48 1992 Per Bothner (bothner@rtl.cygnus.com)
12265 * ch-typeck.c (chill_handle_case_label, chill_handle_case_default):
12266 New functions, for code common to CASE actions and expressions.
12267 * chill.y: Replace some code by calls to chill_handle_case_label
12268 and chill_handle_case_default.
12269 * ch-typeck.c (chill_expand_case_expr): Add semantics.
12271 * tree.c: Change doing_chill_thang from extern to common.
12273 Mon Nov 23 18:34:22 1992 Per Bothner (bothner@rtl.cygnus.com)
12275 * ch-tree.def: New CASE_EXPR type, for case expressions.
12276 * ch-expr.c (chill_expand_expr): Hook for CASE_EXPR.
12277 * ch-typeck.c (chill_expand_case_expr): New function.
12278 Placeholder to implement case expressions.
12279 * ch-typeck.c (chill_expand_result, chill_expand_return):
12280 Handle mode-unspecified tuples and case expressions in
12281 the context of RETURN and RESULT actions.
12282 * chill.y (assignaction): Handle case expressions in the
12283 context of the RHS of an assignment action.
12284 * chill.y (caseaction): Remove spurious duplicate OF in grammar.
12285 * chill.y: Handle labeled structure tuples.
12286 * chill.y: New rules to parse CASE expressions.
12287 * tree.c (build_function_types): Allow Chill functions
12288 to return arrays and functions.
12290 Wed Nov 18 13:50:28 1992 Per Bothner (bothner@rtl.cygnus.com)
12292 * ch-typeck.c (chill_expand_tuple): New function. Expand a
12293 tuple (constructor) given an expected (context) type.
12294 * chill.y: Implement 'LHS := TUPLE' using expand_chill_tuple,
12295 using the mode of the LHS and the expected type of the TUPLE.
12296 * chill.y: Implement initialization.
12297 * chill.y: Fix some syntax bugs (forbidlist must be surrounded
12298 by parentheses), and remove or note ambiguities.
12299 * chill.y: Started converting layout style to be like c-parse.in.
12300 * chill.y: Implement IF expressions.
12301 * chill.y: Added syntax rules for tuples. Labelled and unlabelled
12302 array tuples should now work (in some contexts).
12303 * ch-actions.c: Initialize doing_chill_thang to 1.
12304 * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
12305 initializer, to make pushdecl and finish_decl work.
12306 * c-decl.c (convert_for_assignment): If Chill, don't convert
12307 function and arrays into pointers. (Maybe functions should
12308 still be converted?)
12309 * c-typeck.c (grokdeclarator): Allow functions in Chill
12310 to return arrays and functions.
12312 Mon Nov 16 15:40:47 1992 Per Bothner (bothner@rtl.cygnus.com)
12314 * chill.y (exprlist_get_single): New function, used when
12315 parsing tuples.
12316 * chill.y: Re-did parsing of tuples to remove ambiguities.
12317 This was a bitch.
12319 Tue Nov 10 16:30:55 1992 Per Bothner (bothner@rtl.cygnus.com)
12321 * ch-typeck.c (chill_expand_result); Set TREE_SIDE_EFEFCTS
12322 flags on assignment to result.
12323 * ch-typeck.c (build_chill_array_ref): Subtract lower
12324 bound of domain if non-zero. Preliminary hook for range checking.
12325 * ch-tree.h, chill.l: Combine variables range_check and
12326 range_check_disabled into global variable range_checking.
12327 * ch-tree.h: Better definitions of CH_CLASS_IS_VALUE
12328 CH_CLASS_IS_DERIVED.
