3443 (kept_level_p, pushlevel, poplevel): Simplify.
3445 * decl.c (init_decl_processing): Don't call init_iterators.
3446 * Makefile.in (C_OBJS): Don't get ../c-iterator.o - not needed.
3448 Thu Sep 15 05:54:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3450 * lex.l (readstring): Add processing of control sequence
3451 in character string literals. The granting mechanism writes
3452 this to grant files.
3454 Tue Sep 13 06:19:42 1994 Wilfried Moser (moser@rtl.cygnus.com)
3456 * expr.c (compare_records): In case of -fpack do always
3457 a memcmp instead of comparing each field of the
3458 structure. If the structure is a variant structure,
3461 Mon Sep 12 13:15:09 1994 Per Bothner (bothner@cygnus.com)
3463 * grant.c (write_spec_module): Add cast, to avoid PCC warning.
3464 * grant.c (header_template): Don't use ANSI-specific string
3465 literal concatenation.
3467 Fri Sep 9 01:53:30 1994 Wilfried Moser (moser@rtl.cygnus.com)
3469 * tasking.c (get_process_wrapper_name): New function.
3470 (add_taskstuff_to_list): Add a new argument, which is
3471 the entrypoint of a process.
3472 (build_process_header): Change PROCESS arguments to be
3473 like arguments of a function. There will be a wrapper
3474 which is the real entry point for a PROCESS. This wrapper
3475 is automatically build after a PROCESS definition and gets
3476 as argument a pointer to a structure looking like the
3477 arguments of the PROCESS. This wrapper will call the
3478 PROCESS (see build_process_wrapper).
3479 (build_process_wrapper): New function (see above).
3480 (build_start_process): Change processing of arguments.
3481 (tasking_setup): Add processing of a different entry point
3482 in case of PROCESSes.
3484 * parse.c (parse_process_definition): Add call to
3485 build_process_wrapper.
3486 * parse.c (end_function): Remove the poplevel() call.
3487 build_process_header no longer makes the corresponding
3490 * grant.c (print_proc_tail): Remove special processing
3491 of PROCESSes, they look now like normal functions.
3493 * decl.c (init_decl_processing): Add declaration of memcmp
3496 * ch-tree.h: Add new prototype for build_process_wrapper,
3497 change prototypes for add_taskstuff_to_list and
3498 build_process_header.
3500 * grant.c (write_spec_module): Write GNUCHILL and gcc
3501 version into grant file.
3503 * Make-lang.in (CHILL_FLAGS_TO_PASS): Add passing of CC and
3504 GNUCHILL_VERSION to ch/Makefile.
3505 * Make-lang.in (CHILL.mostlyclean): Add ch/ch-version.c.
3507 * Makefile.in (CHILL_OBJS): Add ch-version.o. ch-version.c
3508 will get generated every time a new Makefile will get
3510 * Makefile.in (GNUCHILL_VERSION): Remove it, its defined in
3513 * chill.in: In case of -fgrant-only pass "-S -o /dev/null"
3514 to the compiler to avoid generation of an object file.
3516 Thu Sep 8 12:07:28 1994 Per Bothner (bothner@kalessin.cygnus.com)
3518 * convert.c (display_int_cst), ch-tree.h: New function.
3519 * convert.c (digest_array_tuple): Use digest_int_cst to
3520 provide better error messages. Return error_mark_node on error.
3521 * grant.c (decode_const): Simplify by using digest_int_cst.
3522 * grant.c (format_character, find_assoc): Removed.
3524 * decl.c (do_decl): Add missing TREE_CHAIN.
3526 * decl.c (finish_incomplete_decl): Removed.
3527 (init_decl_processing): Don't set incomplete_decl_finalize_hook.
3528 (finish_decl): Remove old C-specific code to deduce size of
3529 array from initialization.
3530 (complete_array_type): Just make it abort.
3532 * except.c (finish_handler_array): Avoid calling C-specific kludge
3533 complete_array_type.
3535 * convert.c (digest_constructor): Rename, and re-write to:
3536 (digest_array_tuple, convert): No longer use the code in
3537 ../c-typeck.c; use a Chill-only implementation (sigh).
3539 * typeck.c (chill_expand_tuple): Remove unneeded call to
3540 complete_array_type.
3542 * expr.c (fold_set_expr), grant.c (decode_constant),
3543 typeck.c (expand_constant_to_buffer): Update name of called
3544 function unpack_set_constructor to get_set_constructor_bits.
3545 * expr.c (powersetlen ): Remove redundant call to convert.
3547 * ch-tree.h (unpack_set_constructor): Removed obsolete declaration.
3549 * inout.c (build_chill_writetext): Handle 64-bit integer literals
3550 by trying to convert them to a smaller type.
3552 * lex.l (convert_number): Always use long long type (possibly
3553 unsigned) to avoid problems with constant folding truncation.
3555 Mon Sep 5 08:08:22 1994 Wilfried Moser (moser@rtl.cygnus.com)
3557 * ch-tree.h (enum chill_built_in_function): Add BUILT_IN_QUEUE_LENGTH.
3558 Add new prototype (see tasking.c).
3560 * expr.c (build_generalized_call): Add processing of
3561 BUILT_IN_QUEUE_LENGTH.
3563 * tasking.c (build_queue_length): New function.
3565 * tasking.c (tasking_init): Add new external function definition.
3567 Thu Sep 1 15:38:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3569 * lex.l (default_lex): New function. Progress towards
3570 getting rid of [f]lex.
3572 * lex.l (convert_number): Use mul_double and add_double.
3573 Set result type to a reasonable type in which the literal
3574 will fit. Give error message if literal is too big.
3576 * lex.l (equal_number): Switch (temporarily) to permanent obstack.
3578 * typeck.c (build_chill_slice_with_range): Check for empty
3579 slice *after* we have checked for upper/lower limit in range.
3581 * grant.c (decode_mode): Remove unused code. (BOOL and
3582 CHAR ranges are represented as INTEGER_TYPEs.)
3584 * tasking.c (build_process_header): Add missing call to
3585 expand_start_bindings.
3586 * parse.c (end_function): Add missing expand_end_bindings.
3588 Wed Aug 31 17:25:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3590 * decl.c (init_decl_processing): Set set_alignment.
3592 Tue Aug 30 16:40:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
3594 * actions.c (print_missing_cases, check_missing_cases,
3595 BITARRAY_TEST, BITARRAY_SET): New functions and macros,
3596 to check for completeness of case actions and expressions.
3597 * decl.c (c_decode_option, init_decl_processing):
3598 Don't set warn_switch.
3599 * expr.c (chill_expand_case_expr): Call check_missing_cases
3600 instead of check_for_full_enumeration_handling.
3601 * parse.c (parse_case_actions): Call check_missing_cases.
3603 * expr.c (build_chill_binary_op): Remove some dead code.
3604 * expr.c (chill_truthvalue_conversion): Call build_chill_binary_op
3605 instead of build_binary_op.
3606 * ch-tree.h (binary_op_error, build_binary_op): Unused. Removed.
3608 * parse.c (end_function): Use kept_level_p in parameter to
3609 poplevel. This reverts a June 13 change.
3611 Fri Aug 26 11:50:19 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3613 * configure: Ignore --without, as ../configure does.
3615 Wed Aug 24 01:17:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3617 * lex.l: Change rule for decimal numbers to allow identifiers
3618 to start with an underscore (_).
3620 Fri Aug 19 16:38:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
3622 * tasking.c (build_receive_signal_case_label): Remove backwards
3623 chill_convert_for_assignment (which converted whatever garbage
3624 was in the *target* to the type of the signal argument!).
3626 Fri Aug 19 07:10:43 1994 Wilfried Moser (moser@rtl.cygnus.com)
3628 * inout.c (build_chill_io_list_type, build_enum_tables),
3629 tasking.c (build_tasking_struct): Temporarily reset
3630 maximum_field_alignment to 0, so that the compiler-built
3631 data structures needed by the RTS can be independent of -fpack.
3633 Thu Aug 18 13:39:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3635 * typeck.c (build_init_struct): Temporarily reset
3636 maximum_field_alignment to 0, so that the compiler-built
3637 data structures needed by the RTS can be independent of -fpack.
3639 Wed Aug 17 23:48:33 1994 Wilfried Moser (moser@rtl.cygnus.com)
3641 * parse.c (parse_primval, expect, parse_on_exception_list):
3642 Print error message only in pass 2.
3644 Wed Aug 17 13:47:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3646 * decl.c (switch_to_pass_2): Revert June 13 change,
3647 (Don't exit after pass 1 if an error was found.)
3649 * ch-tree.def (SLICE_EXPR): New tree-code.
3650 * typeck.c (build_chill_slice): For building a slice of a
3651 bit-string, just generate a SLICE_EXPR.
3652 * decl.c (init_decl_processing): Declare __pscpy.
3653 * actions.c (chill_expand_assignment): Handle a SLICE_EXPR
3654 on the LHS of assignment, by calling __pscpy.
3655 * expr.c (chill_expand_expr): Handle SLICE_EXPR (as a RHS
3656 value) by using __psslice to copy slice to a temp.
3658 Wed Aug 17 05:52:44 1994 Wilfried Moser (moser@rtl.cygnus.com)
3660 * Make-lang.in: Change version of GNUCHILL compiler to 1.4.1.
3661 * expr.c (build_chill_length): Enable LENGTH built-in to process
3662 Buffers and Events too (Z.200/1992).
3663 * lex.l (yywrap): Always set yyin to finput and/or grt_in. On
3664 a linux system the previous version was not able to run.
3665 * tasking.c: Correct processing of infinite buffer- and event-length
3666 to avoid RANGEFAIL warning.
3668 Thu Aug 11 11:46:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3670 * parse.c (parse_if_expression_body): Don't call the C-specific
3671 build_conditional_expr. Just do build_nt (COND_EXPR, ...).
3672 * convert.c (convert): Convert a COND_EXPR by converting
3675 * convert.c (convert): Don't call convert before
3676 convert_to_reference. It's apt to do weird and unneedful things.
3677 * convert.c (convert): If the expression is varying, just call
3678 varying_to_slice, which simplifies quite a bit.
3680 * ch-tree.h (varying_to_slice): Add prototype.
3681 * typeck.c (varying_to_slice): Remove prototype.
3683 * satisfy.c (satisfy): Move case PAREN_EXPR from type 'e'
3686 * except.c (emit_setup_handler): Temporarily reset the
3687 maximum_field_alignment to zero so the compiler's exception
3688 data structures can be compatible with the run-time system,
3689 even when we're compiling with -fpack.
3691 * expr.c (compare_records): Call saved_if_needed on operands.
3693 * expr.c (build_set_expr case NE_EXPR): Don't use __nepowerset
3694 which has been reimplemented to just call __eqpowerset and
3695 invert the result. Inline this new implementation by
3696 handling as EQ_EXPR, and inverting the result.
3697 * decl.c (init_decl_processing): Don't define unused __eqpowerset.
3699 * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
3700 type boolean_type_node, not void_type_node. (Fixing this
3701 avoids a crash in the back-end.)
3703 * grant.c (decode_constant): In a CALL_EXPR, if the argument
3704 list is not a TREE_LIST (as in string repetiation), don't
3707 Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3709 * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
3710 CONST_DECL is from a SET definition. (This is safer than
3711 checking that the type is ENUMERAL_TYPE, because synonym
3712 definitions may have a NULL TREE_TYPE.)
3713 Also, if we have duplicate enums whose types are identical,
3715 * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
3716 an extra 'quiet' parameter, which is true if we're called from
3717 bind_sub_modules. (In that case an error message about duplicated
3718 decls would be repeated later, so suppress it.)
3720 * parse.c (stmt_count): Removed, not used.
3721 (INIT_ACTION): Call emit_line_note only if !ignoring.
3722 (parse_begin_end_block): Do INIT_ACTION even if ignoring.
3724 Fri Aug 5 12:39:11 1994 Per Bothner (bothner@kalessin.cygnus.com)
3726 * parse.c (parse_untyped_expr): Add missing semi-colon.
3728 Thu Aug 4 17:40:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
3730 * parse.c (parse_untyped_expr): Fix various problem for the
3731 case that we see a '(': Add missing 'case' keyword.
3732 Only recurse if '(' is followed by 'if', 'case' or '[',
3733 and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
3735 * parse.c (parse_send_action): Remove extra nreverse.
3737 Thu Jul 28 04:00:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3739 * expr.c (build_allocate_global_memory_call, build_allocate_memory_call):
3742 Tue Jul 26 22:48:15 1994 Michael Tiemann (tiemann@blues.cygnus.com)
3744 * parse.c (parse_untyped_expr): Added missing "case" before LPRN.
3745 Added a missing call to `require' as well.
3747 Tue Jul 19 10:30:12 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3749 * lex.l (yywrap): Define as yywrap_chill to avoid conflicts with
3750 the extern declaration in the flex skeleton.
3752 Mon Jul 18 23:06:04 1994 Per Bothner (bothner@kalessin.cygnus.com)
3754 * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
3755 Check the type of the instance expr using CH_COMPATIBLE,
3756 and not just == instance_type_node. (This allows
3757 the expression to have mode READ INSTANCE).
3758 * tasking.c (build_instance_type): Give instance_type_node
3759 a non-null novelty (i.e. different from a struct).
3760 * tasking.c (build_receive_case_start, build_delay_case_start):
3761 Check that for a location using CH_LOCATION_P.
3763 Mon Jul 18 13:22:23 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
3765 * expr.c (finish_chill_unary_op): Use TREE_SET_CODE not TREE_CODE
3766 to modify a tree code.
3768 Mon Jul 18 11:24:57 1994 Bill Cox (bill@rtl.cygnus.com)
3770 * convert.c (digest_structure_tuple): Fix thinko in TREE_CODE
3773 Mon Jul 18 05:40:15 1994 Doug Evans (dje@canuck.cygnus.com)
3775 * decl.c (warn_bad_function_cast): Define so cc1chill will link.
3777 Thu Jul 14 18:37:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3779 * parse.c (parse_send_action): Do tree_cons *before* checking
3782 Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3784 * convert.c (digest_structure_tuple): Don't use convert to
3785 coerce initial value, use chill_convert_for_assignment instead.
3786 (Thus we also get range_checking.)
3788 * expr.c (build_chill_card): Use force_addr_of instead of
3789 build_chill_addr_expr.
3791 * loop.c (build_temporary_variable): Stylistic tweak.
3792 * loop.c (maybe_make_for_temp): Initialize temp using
3793 explicitly, not using assignment. Avoids a problem if
3794 the expression is read-only.
3795 * typeck.c (smash_dummy_type): Always used the saved TYPE_NAME
3796 and CH_NOVELTY_FLAG.
3798 Wed Jul 6 20:12:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3800 * expr.c, ch-tree.h (finish_chill_unary_op): New function,
3801 based on code ripped out of build_chill_unary_op.
3802 (build_chill_unary_op): Call finish_chill_unary_op unless pass==1.
3803 * satisfy.c (satisfy): Call finish_chill_unary_op when needed.
3805 Mon Jun 27 11:29:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3807 * tree.c (save_if_needed), ch-tree.h: New function.
3808 * typeck.c (build_chill_slice_with_range,
3809 build_chill_slice_with_length): Call save_if_neeed on array arg.
3810 * expr.c (varying_to_slice): Re-write to use save_if_needed.
3812 * typeck.c (extract_constant_from_buffer): Handle BOOLEAN_TYPE.
3814 Mon Jun 27 01:11:10 1994 Wilfried Moser (moser@rtl.cygnus.com)
3816 * inout.c (build_chill_io_list_type): Change layout of __tmp_WIO_list
3817 that it is always the same, regardless if compiled with -fpack
3820 Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3822 * lex.l (yywrap): Kludge to work around mis-synchronization
3823 between lexer (which read ahead) and parser: Don't emit
3824 (left-over) uze_seizefile directives at the end of file.
3826 * typeck.c (build_chill_array_ref): Allow the derived
3827 array indexing syntax for arrays of bit strings.
3828 Add a comment explaining why.
3830 * typeck.c, ch-tree.h (string_assignment_condition): Change
3831 the interface. Return a boolean expression (which can be
3832 used in a conditional at run-time); never expand anything.
3834 * actions.c (chill_convert_for_assignment): Check
3835 string_assignment_condition here, rather than in callers.
3836 * actions.c (chill_expand_assignment): Don't need to check
3837 string_assignment_condition here.
3838 * expr.c (build_chill_function_call): Likewise.
3839 * satisfy.c (safe_satisfy_decl): Update accordingly.
3840 * decl.c (do_decl): Simplify testing and conversion by
3841 deferring everything to chill_convert_for_assignment.
3843 * parse.c: Combine the two variables 'ignore_exprs' and
3844 'ignore_actions' into one variable called 'ignoring'.
3845 * ch-tree.h: Add 'extern int ignoring'.
3846 * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
3847 Rename ignore_actions and ignore_exprs to ignoring.
3848 Remove unneeded extern declarations.
3849 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3850 build_chill_arrow_expr, build_generalized_call, build_delay_action,
3851 build_buffer_type, build_event_type): I changed my mind. It is
3852 cleaner to check for 'ignoring' in the parser, rather than here.
3853 * parse.c (parse_action, parse_primval, parse_opt_mode):
3854 Therefore we must check for ignoring here.
3855 * parse.c (parse_loc_declaration): Set ignoring in pass 2
3856 when parsing the mode.
3858 * tasking.c (generate_tasking_code_variable): Do arithmetic
3859 on signal_code etc using unsigned rather than signed shorts.
3861 * grant.c (static char* current_grant_modename): Removed.
3862 * grant.c (decode_decl case CONST_DECL): Remove error message.
3864 * Make-lang.in (CHILL_SRCS): Add $(srcdir)/ch/parse.c.
3865 * Makefile.in: Fix dependencies for parse.o.
3866 Remove some duplicate dependencies for $(TREE_H).
3868 Mon Jun 13 14:25:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3870 * typeck.c (build_chill_cast): Allow a value cast between
3871 non-discrete object of the same size, but with a pedwarn.
3872 * typeck.c (bit_string_assignment_condition,
3873 char_string_assignment_condition): Merge near-duplicate functions
3874 and place the code in string_assignment_condition.
3876 * decl.c (parm_flag, declare_parm_level, in_param_level_p):
3878 * decl.c (start_chill_function, finish_chill_function): Make
3879 parameter level have same nesting level as body, as required by Z200.
3880 * decl.c (switch_to_pass_2): Always exit if an error has been found.
3881 * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
3882 generated from GRANT ALL.
3883 * decl.c (lookup_name_for_seizing): Don't seize from
3884 the nesting level of builtins (predefined objects).
3885 * decl.c (lookup_name_for_seizing): Make more robust on error.
3887 * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
3888 be 'RESULT' (or 'result'). This makes it more accessible from gdb.
3889 Also, use do_decl to declare it, so that debugging symbols are
3890 generated. And, re-arrange so that actions that need to
3891 be done both passes (such as push_levels) use the same code.
3893 * parse.c (get_type_of): If ignore_exprs, don't lookup name.
3894 * parse.c (end_function): Fix poplevel params.
3895 * parse.c (expect): Don't read forwards on an error.
3896 * parse.c (parse_field): Don't define two tag_list locals!
3897 * parse.c (parse_pass_1_2): Better error message.
3899 * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
3900 parse_opt_mode, rather than vice versa. If parse_opt_mode
3901 returns NULL_EXPR, then parse_mode gives an error.
3902 Change parse_opt_mode (and any functions it calls) to only
3903 return NULL_TREE if there is no mode (even on ignore_exprs).
3904 (parse_set_mode, parse_structure_mode, parse_procedure_mode):
3905 Never return NULL_EXPR.
3906 * tasking.c (build_buffer_type, build_event_type): Return
3907 void_type_node instead of NULL_EXPR if ignore_exprs is true.
3909 * parse.c (parse_synonym_definition): Call parse_untyped_expr
3910 only if we have a mode.
3911 * parse.c (parse_send_action): Parse list of untyped_expr's,
3912 rather than a list of (typed) expressions.
3913 * parse.c (parse_primval): Emit error if '[' seen without
3914 preceding mode name. (If this is to be allowed, call
3915 parse_untyped_expr instead.)
3917 * parse.c (parse_array_index): Renamed to ...
3918 (parse_index_mode): ... to match Z200 terminology.
3919 Re-write to resolve some of the nastier ambiguities,
3920 and allow things like ' CHAR(10) : CHAR(20) '.
3922 * parse.c (parse_tuple_element): Change interface to return
3923 reversed list, so don't call nreverse.
3924 * parse.c (parse_tuple): No longer nreverse element list here.
3925 * parse.c (parse_opt_element_list): Do nreverse here instead.
3926 * parse.c (parse_case_label_list): Call nreverse at end.
3928 Fri Jun 10 15:36:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
3930 * typeck.c (chill_similar): Remove bogus "else".
3932 Wed Jun 8 00:01:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
3934 * ch-tree.h (TYPE_ARRAY_MAX_SIZE): New macro (and comment)
3935 to make it clearer that we are using TYPE_MAX_VALUE in a special way.
3936 * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
3937 * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
3938 * convert.c (convert): When converting a fixed string/array
3939 to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
3940 of (the type of) the padding.
3941 * convert.c (convert): If the concatenation is non-constant, use
3942 the low-level 'build' to set the type of the result (which is usually
3943 a fixed-size array) rather than depend on build_chill_binary_op
3944 to figure it out (it's unable to simplify the size to a constant).
3946 Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
3948 * lang.c (lang_decode_option): Let -fspecial_UC imply
3949 -fno-ignore-case without requiring it explicitly.
3950 * lang.c (lang_decode_option): Support (experimentally)
3951 the -fpack and -fno-pack flags.
3953 Thu Jun 2 20:49:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3955 * configure: Add support for --program-prefix and --program-suffix.
3957 Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3959 * convert.c (digest_constructor): Check that initial value
3960 is compatible with element mode before calling convert.
3961 * typeck.c (chill_compatible): A string mode is not compatible
3962 with an untyped constructor.
3963 * decl.c (do_decl): Clean up error messages. Use error_with_decl.
3965 * ch-tree.h: Fix inconsistencies: bool_true_node ->
3966 boolean_true_node, and bool_false_node -> boolean_false_node.
3967 * typeck.c (valid_array_index_): Minor simplification.
3969 Tue May 31 04:33:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3971 * inout.c (build_chill_writetext): Add correct processing
3972 of POWERSET RANGE (setmode).
3974 * lex.l (same_file): Add searching for file(s) in
3977 Fri May 27 14:22:42 1994 Per Bothner (bothner@kalessin.cygnus.com)
3979 * Make-lang.c (CHILL.mostlyclean, CHILL.distdir): Don't list
3980 yacc/bison output files, since the grammer is no longer in yacc.
3981 * config-lang.in (diff_excludes): Likewise.
3983 Thu May 26 16:38:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3985 * gperf, hash.h, lex.l, parse.h: Rename PROCESS_TYPE token
3986 (in some files spelled PROCESS_TYPE_ to avoid clashes
3987 with the PROCESS_TYPE tree_code) to PROCESS_TYPE_TOKEN.
3989 Thu May 26 02:18:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3991 * timing.c (build_cycle_start): Change call to __define_timeout.
3992 * decl.c (init_decl_processing): Change definitions of
3993 __define_timeout and __wait_timeout.
3995 Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
3997 Replace yacc-based parser with a recursive-decent parser.
3998 (This may seem backwards, but Chill [like C++] is not a
3999 language that is remotely LALR(1). Using a R-D parser
4000 allows us to use look-ahead and to back-up to resolve the
4001 difficult ambiguities.)
4003 * parse.c, parse.h: New files, containing new r-d parser.
4004 * Makefile.in: Update accordingly.
4005 * actions.c (chill_convert_for_assignment): Don't return
4006 NULL_EXPR if ignore_exprs is true. It simplifies the parser
4007 if we consistently reserve NULL_EXPR for a missing expression.
4008 * expr.c (build_chill_function_call): Likewise.
4010 * lex.l: Tweaks for new parser.
4011 * lex.l (prepare_paren_colon, paren_paren_colon_level,
4012 paren_level): Ugly hack no longer needed.
4014 * expr.c (build_chill_function_call): Cleanup.
4015 Call chill_convert_for_assignment to convert IN/INOUT
4016 paramaters on both input and output. For LOC parameters,
4017 give error if actual is a non-referable location.
4018 * actions.c (convert_for_assignment): Add new parameter (a
4019 "place" string used in error messages).
4020 * actions.c (adjust_parm_or_field): Removed.
4021 * actions.c (chill_expand_assignment): Take just a single LHS,
4022 and move support for multiple assignments to ...
4023 (expand_assignment_action): ... here. Some cleaning up.
4024 * timing.c (build_cycle_start): Adjust accordingly.
4025 * actions.c (expand_assignment_to_varying_array): Likewise.
4026 * tasking.c (many places): Ditto.
4027 * ch-tree.h: Fix declarations appropriately.
4029 * parse.c (parse_defining_occurrence_list): Return a single
4030 IDENTIFIER_NODE (instead of a singleton list) in the common
4031 case. Minor complication to save a minor amount of space.
4032 * decl.c (do_based_decls): Move guts of code into ...
4033 (do_based_decl): ... this new function.
4034 * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
4035 * decl.c (push_syndecl): Replace by ...
4036 (push_syndecl): ... (which only supports a single name).
4037 (push_modedef): Only handle a single name.
4038 * tasking.c (build_process_header, build_signal_struct_type):
4041 * expr.c (build_generalized_call): Handle string repetition.
4042 * expr.c (build_chill_repetition_op): Change interface.
4043 * grant.c (decode_constant): Allow parameter list to be
4044 a non-TREE_LIST. (Used for string repetition.)
4046 Wed May 25 11:28:48 1994 Per Bothner (bothner@kalessin.cygnus.com)
4048 * lex.l (make_identifier): Replaced by ...
4049 (read_identifier, handle_name): ... new functions.
4050 * lex.l: Parse an identifiers using read_identifier using
4051 read_identifier and handle_name, rather than having [f]lex
4052 do it. (One reason is that lex uses a fixed-size buffer.)
4054 * lex.l (read_directive, skip_directive): New functions.
4055 Use them to parse compiler-directives, instead of rather
4056 ugly and useless use of lexer start conditions.
4058 Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4060 * decl.c (unnamed_module_number): Renamed to ...
4061 (module_number): .. and make non-static.
4062 (push_module): Always increment module_number.
4063 * lex.l (yywrap): Print warning if no modules seen.
4065 * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
4066 decl to current_seizefile_name (which is unreliable).
4067 * grant.c (chill_grant): Set it here instead.
4069 * expr.c (fold_set_expr): Use int_size_in_bytes instead of
4070 TYPE_PRECISION (which is not defined for a SET_TYPE).
4072 Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
4074 Cleanup to remove need for variables in common storage.
4075 * decl.c: Remove unused use of current_obstack.
4076 * actions.c (maybe_chill_check_decl): Remove unused function.
4077 * actions.h, lang.c: Remove uses of doing_chill_thang.
4078 * ch-tree.h (void_list_node): Make extern (rather than common).
4079 * decl.c (void_list_node): Add definition.
4081 Thu May 19 06:54:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
4083 * configure (build): Build canon_host and canon_target
4084 to pass it to all subsequently generated Makefiles (needed
4085 for testsuite/execute in case of cross build).
4087 Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4089 * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
4090 the input type, which loses with the no-longer-new 2-pass
4091 implementation, since the input "type" could be an IDENTIFIER_NODE.
4092 * grant.c (raw_decode_mode): Rename to decode_mode.
4094 Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
4096 * typeck.c (chill_location): Neither a STRING_CST nor a
4097 CONSTRUCTOR is a location.
4098 * typeck.c (chill_root_mode): Convert a function to a
4099 pointer-to-function.
4100 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
4101 build_chill_arrow_expr): If ignore_exprs, return operand
4102 rather than NULL_EXPR. This makes it easier for the parser to
4103 distinguish missing expressions.
4104 * expr.c (build_max_min): Convert the lower bound of a
4105 set to a long before calling run-time routine.
4106 * expr.c (build_chill_pred_or_succ): Use discrete_type_p
4107 to check the argument type.
4108 * expr.c (build_chill_arrow_expr): If argument is not a location,
4109 do a predwarn if it is a STRING_CST or has function type.
4111 Tue May 17 06:05:13 1994 Wilfried Moser (moser@rtl.cygnus.com)
4113 * configure (build): Remove building of canon_host and canon_target.
4114 It doesn't work in any case.
4116 Mon May 16 02:10:35 1994 Wilfried Moser (moser@rtl.cygnus.com)
4118 * configure (build): Build canon_host and canon_target
4119 to pass it to all subsequently generated Makefiles (needed

4121 * Make-lang.in (chill-runtime): Change chill to CHILL in the case
4122 statement to build chill-runtime automatically.
4124 Mon May 9 15:30:08 1994 Doug Evans (dje@canuck.cygnus.com)
4126 * Makefile.in (FLAGS_TO_PASS): Define.
4128 (../cc1chill): Depend on $(OBJDEPS) $(C_OBJS).
4129 * Make-lang.in (cc1chill): Delete dependency on $(OBJS) $(BC_OBJS).
4130 (CHILL.mostlyclean): Use `mostlyclean' as recursive target.
4132 Sun May 8 13:05:00 1994 Per Bothner (bothner@cygnus.com)
4134 * Make-lang.in (cc1chill): Should not depend on libgcc.a.
4136 Thu May 5 18:58:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
4138 * decl.c (copy_lang_decl): New (dummy) function.
4140 Mon May 2 14:33:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
4142 * parse.y (sendaction): Fix thinko (in sense of condition).
4143 * tasking.c (build_receive_case_label): Another thinko.
4145 * parse.y (optsigdest): Force ignore_exprs to 0 while parsing
4148 * decl.c (build_chill_function_type): Don't call layout_type
4149 (since that may prevent parameter or result types being
4150 properly satisfied).
4151 * satisfy.c (satisfy): Layout FUNCTION_TYPEs.
4152 * parse.y (procmode): Call build_chill_pointer_type, rather
4153 than build_pointer_type (which incorrectly sets TYPE_SIZE).
4155 * parse.y (get_type_of): Handle TYPE_DECL (again).
4156 * parse.y (optresultspec): Call build_chill_reference_type, rather
4157 than build_reference_type (which incorrectly sets TYPE_SIZE).
4158 * parse.y (range_or_mode): Rename to plain range, since it
4159 no longer matches modename.
4160 * actions.c (chill_handle_case_label_range): New function, with
4161 functionality moved out of chill_handle_case_label.
4162 * actions.c (chill_handle_case_label): Handle here the case that
4163 the label_value is a TYPE_DECL (modename). Also clean up some.
4164 * typeck.c (build_chill_slice_with_length): Convert max_index
4165 to the type of min_value. (Old code broke on varying strings.)
4167 Sun May 1 13:53:36 1994 Doug Evans (dje@canuck.cygnus.com)
4169 * Makefile.in (BC_OBJS): Delete all references
4170 (OBJS): Cat ../stamp-objlist to get language independent files.
4171 (../cc1chill): Delete dependency on $(OBJS).
4172 * Make-lang.in (cc1chill): Depend on stamp-objlist.
4174 Sat Apr 30 14:50:15 1994 Per Bothner (bothner@kalessin.cygnus.com)
4176 * lex.h, lex.c: Remove lastiddecl.
4177 * lex.l (name_type_signal): Simplify. We no longer check for
4178 TYPENAME or SIGNALNAME (which was unreliable with two passes).
4179 Also rename to make_identifier.
4180 * parse.y: Cleaned up grammar to not need SIGNALNAME or TYPENAME.
4181 * Makefile.in (stamp-parse); One conflict fewer!
4182 * parse.y (rccase_label_flag): Moved to tasking.c.
4183 * parse.y (rccase_label): Move most of the logic to
4184 build_receive_case_label in tasking.c.
4185 * parse.y (sendaction): Re-write to not depend on SIGNALNAME.
4187 * parse.y (name): Do name lookup here (and not in location).
4188 * parse.y: Replace most uses of NAME by higher-level non-terminals:
4189 simple_name_string, name_string, defining_occurrence, or name.
4191 * tasking.c (build_receive_signal_case_label,
4192 build_receive_buffer_case_label): New functions, split out from
4193 build_receive_case_label.
4194 * tasking.c (build_receive_case_label): Change parameters
4195 and return type. Moved stuff here (from the parser).
4196 * tasking.c (struct rc_state_type): Removed had_errors.
4197 Return error_mark_node instead.
4198 * tasking.c (build_rccase_set_error), ch-tree.h: Removed.
4200 * expr.c (build_generalized_call): If func is a signal type,
4201 call build_signal_descriptor.
4203 * parse.y (arrayindex): Renamed to index_mode, to match Z.200.
4204 * parse.y (ioindexmode): Removed; use index_mode instead.
4205 * expr.c (build_generalized_call): If args is a RANGE_EXPR,
4206 we have either a slice or a range mode, depending on func.
4207 * parse.y (index_mode): If we got an 'expr', only allow a name,
4209 * parse.y (call): A slice with both end points can be a range
4210 mode, so defer handling to build_generalized_call (or index_mode).
4212 * typeck.c (build_chill_slice_with_length): Fix type-checking.
4213 * typeck.c (chill_novelty): Undo (part of) change of April 28:
4214 The novelty of a range mode is the novlety of the parent.
4215 * typeck.c (chill_root_mode): Don't return integer_type_node
4216 if argument has non-nil novelty.
4218 * decl.c (global_bindings_p): Return -1 as true, for the sake
4219 of variable_size (in ../stor-layout.c).
4221 Fri Apr 29 13:42:43 1994 Per Bothner (bothner@kalessin.cygnus.com)
4223 * parse.y: Remove TYPENAME and modename. These are now plain
4224 NAMEs. Modify parsing actions appropriately.
4225 * expr.c (build_generalized_call): Handle the case that
4226 TREE_CODE (func) == TYPE_DECL (as in a cast).
4227 * lex.l (name_type_signal): Never return TYPENAME.
4228 * parse.y (get_type_of): If pass 1, just return the argument.
4230 * decl.c (do_decl): If an initializer has the wrong type,
4231 replace it by NULL_TREE, to avoid subsequent errors.
4233 Thu Apr 28 15:21:56 1994 Wilfried Moser (moser@rtl.cygnus.com)

4264 of BUFFER's and SIGNAL's.
4265 * tasking.c (build_receive_case_end): Do only general processing and
4266 call one of the above mentioned functions.
4267 * tasking.c (build_delay_case_start, build_delay_case_label,
4268 build_delay_case_end): Rewritten due to new implementation of events.
4269 * tasking.c (build_delay_action): Rewritten due to new implementation
4271 * tasking.c (expand_send_buffer), ch-tree.h: New function.
4272 * timing.c (build_at_action, build_cycle_start, build_cycle_end),

4277 * typeck.c (smash_dummy_type): Handle the special case of a
4278 NEWMODE of a range mode, as required by Z200, by creating a
4279 new parent mode with the new novelty (and casting the min
4280 and max of the range to teh new parent mode).
4281 * typeck.c (chill_novelty, chill_root_mode): Remove special
4282 kludges for of NEWMODE ranges.
4283 * expr.c (build_chill_lower_or_upper): New function, combining
4284 the "guts" of build_chill_lower and build_chill_upper.
4285 * expr.c (build_chill_lower_or_upper): Simplify; no longer
4286 need to kludge the novelties.
4288 * typeck.c (valid_array_index_p): A string index expression
4289 need not be Compatible with the index type; only similar.
4291 * decl.c (layout_chill_variants): If error seen, skip stuff
4292 (rather than aborting or crashing).
4293 * decl (push_modedef): If newdecl's type is an error mark,
4294 continue rather than aborting.
4296 Thu Apr 28 02:07:42 1994 Doug Evans (dje@cygnus.com)
4298 * Make-lang.in: Update of directory reorg from fsf.
4299 * config-lang.in: Ditto.
4301 Mon Apr 25 13:09:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
4303 * typeck.c (chill_similar): Check RECORD_TYPEs properly,
4304 * convert.c (convert): If all else fails, just call convert1.
4305 Thus we can now convert RECORD_TYPEs (assuming they are similar).
4307 * parse.y, lex.l: Remove BUFFERNAME (use location/expr instead).
4308 * parse.y: Re-do BUFFER handling (similar to previous EVENT change).
4309 * grant.c (raw_decode_mode): Re-do BUFFER mode handling.

4315 * parse.y (modename): No longer match SIGNALNAME. Instead, add it
4316 to name and simple_name_string. This removes a reduce/reduce conflict.
4317 * Makefile.in (stamp-parse): Expect fewer conlicts.
4319 * lex.l (yywrap): Move check for circularly seizeing current
4320 grant-file from here ...
4321 * lex.l (handle_use_seizefile_directive): ... to here.
4322 This is to avoid calling stat on a not-yet written grantfile,
4323 now that we're using same_file (which calls stat).
4324 * grant.c (set_use_this_gf): Removed.
4325 * grant.c (set_default_grant_file): Set grant_file_name here,
4326 because we need it earlier (due to above lexer change).
4328 * typeck.c (layout_chill_struct_type): Remove useless code to
4329 remove zero-width bitfield (which messes up CONST_DECLs).
4331 Sat Apr 23 13:16:39 1994 Bill Cox (bill@rtl.cygnus.com)
4333 * Makefile.in (check): Assure that 'ld' is available before checking.
4335 Thu Apr 21 13:23:54 1994 Per Bothner (bothner@kalessin.cygnus.com)
4337 * grant.c (print_an_int): Removed.
4338 (raw_decode_mode): Generalized to use decode_constant

4350 Re-implement EVENT modes to support general EVENT objects
4351 (and not just EVENT names), according to Z200. (Not finished!)
4352 * tasking.c, ch-tree.h (max_queue_size): New function.
4353 * parse.y (dcalternative, event_list, event_list_head): New
4354 implementation of DELAY CASE, avoiding parsing ambiguities.

4422 * actions.c (chill_expand_assignment): Check for compatibility
4423 _after_ "expanding out" a binary operation. This fixes
4424 the case "STRING //:= CHAR".
4426 * lex.l (equal_number): Convert symbol to integer_type_node, to
4427 force the value to be INT-derived (and avoid novelty conflicts).

4531 * typeck.c (build_chill_modify_expr): Simplify.
4533 Sun Mar 27 19:30:25 1994 Bill Cox (bill@rtl.cygnus.com)

4569 * expr.c (build_generalized_call): Revert previous change.
4570 To do this correctly, we need a new parsing mechanism, and

4592 * configure: Generate better .gdbinit files.
4594 Tue Mar 22 11:59:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
4596 * actions.c (check_range): Don't emit dynamic checks
4597 if not current_function_decl.

4622 type explicitly. Do that.
4623 * satisfy.c (safe_satisfy_decl): Correct range-checking code.
4625 Mon Mar 21 16:25:07 1994 Bill Cox (bill@rtl.cygnus.com)

4640 * expr.c (chill_expand_expr): Code to expand SET_IN_EXPR,

4642 conversions (because we're now using build_chill_function-call).
4643 * actions.c, decl.c, expr.c, grant.c, parse.y, typeck.c:
4644 Use SET_IN_EXPR in place of IN_EXPR.
4646 * expr.c (build_compare_discrete_expr), ch-tree.h: New function,
4647 with code moved from build_compare_expr.
4648 * expr.c (build_compare_expr): Re-enable compatibility test.

4675 to be compatible with the N-value class, with suitable M and N.
4676 * typeck.c (build_chill_slice): Don't smash a void TREE_TYPE.

4679 * expr.c (build_compare_expr): Fix thinko. Add save_exprs.
4681 * expr.c (build_compare_expr): Fix a transcription bug
4682 (for converting NULL INSTANCEs). Also #include convert.h.

4685 Works even if their types have different TREE_UNSIGNED.
4686 * expr.c (finish_chill_binary_op): Moved code dealing with
4687 the comparison operators from here ...
4688 * expr.c (build_compare_expr): ... to new function here.

4693 * typeck.c (valid_array_index_p): Various cleanups,

4713 to have consistent operand types.
4714 * typeck.c (valid_array_index_p): Change interface to pass
4715 validity conditions back on caller's TREE_LIST. We
4716 cannot link the conditions to anything which a
4717 layout_type routine will expand, since that will occur
4718 before the exception handler is set up.
4719 Change calls to valid_array_index_p also.
4721 Fri Mar 18 14:40:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
4723 * actions.c, except.c, loop.c, tasking.c: Call

4729 function build_unary_op (e.g. by calling build1 directly).
4731 * typeck.c (chill_equivalent): Change to force failure
4732 for non-matching integral types (even if not ranges).
4734 * typeck.c, ch-tree.h (build_chill_slice): Make non-static.
4735 * expr.c (varying_to_slice): Call build_chill_slice (and not
4736 build_chill_slice_with_length, which does bunches of range
4737 checking and does not allow the length to be zero).
4738 * convert.c (convert): Fix off-by-one error.
4739 * actions.c (chill_expand_array_assignment): Minor cleaning up.

4744 take *two* pointer parameters, not one.
4745 * satisfy.c (satisfy): Only call the appropriate layout routine
4746 if TYPE_SIZE is 0 (i.e. type hasn't already been laid out).
4747 * typeck.c (build_chill_slice_with_length): Fix Bill's previous fix.

4758 * typeck.c (build_chill_slice), expr.c (chill_expand_expr
4759 [case CONCAT_EXPR]): Remove kludge setting slice size upper bound
4760 in TYPE_LANG_SPECIFIC, and restore kludge setting it in MAX_VALUE.
4761 * typeck.c (build_chill_slice): Use TYPE_MAX_VALUE of
4762 array_type if needed for size upper bound of slice_type.
4763 * expr.c (build_concat_expr): Improve calculation of size upper bound.
4765 * typeck.c (valid_array_index_p): Check compatibility using
4767 * typeck.c (build_chill_slice_with_length); For now revert
4768 calling valid_array_index_p on length. (It makes it harder
4769 to realize when the slice is constant length.)
4770 * expr.c (build_chill_indirect_expr): Minor tweak. (This
4771 seems to work around a weird C compiler bug. ??)
4773 * expr.c (build_chill_function_call): Cleanup so it doesn't
4774 call build_function_call (in c-typeck.c).
4775 * typeck.c, expr.c: Use build_chill_function_call instead of
4776 build_function_call (in c-typeck.c).
4778 * parse.y (discrete_mode): Move some of the rules from
4779 non_array_mode into new non-terminal.
4780 (arrayindex): Use discrete_mode (with NAME and TYPENAME) to
4781 avoid some misparses.

4783 * convert.c (digest_structure_tuple): Add missing parameter.
4784 * decl.c (comptypes): Remove unused prototype.
4785 * decl.c (build_chill_function_type): Handle NULL return_type
4786 correctly (convert to void_type_node).
4787 * decl.c (init_decl_processing): layout boolean_type_node *after*
4788 we've set it's TYPE_MIN_VALUE and TYPE_MAX_VALUE.
4790 Wed Mar 16 16:08:22 1994 Bill Cox (bill@rtl.cygnus.com)

4793 * convert.c (convert): Correct calculation of padding length.
4794 * decl.c (grok_chill_fixedfields): Move ignore_exprs test to
4795 parse.y where it belongs. This permits the removal of a kludge
4796 in make_process_struct.

4810 * expr.c (chill_expand_expr): Call build_chill_array_ref to get
4812 (build_hill_lower, build_chill_upper): Return value now inherits
4813 the novelty of the input parameter.
4814 (varying_to_slice): Use CH_NOVELTY macro rather than calling
4815 chill_novelty directly.
4816 * grant.c (newstring): Make len unsigned and cast xmalloc parameter
4818 (print_integer_type): Pass string value as APPEND's second parameter.

4860 * decl.c (finish_chill_function, finish_decl): Provide the
4861 new permanent_allocation flag.

4894 when processing a SEIZEd PROCESS declaration. This prevents
4895 grox-fixed_fields from returning a NULL, and indirectly protects

5049 Wed Feb 23 15:07:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
5051 New cleaner solution to the following problem:
5052 Chill allows an action to be followed by an ON-handler.
5053 But we don't know if an action has a handler until we've parsed
5054 its end, yet we want to generate extra code to set up an
5055 exception handling contour only if needed. The old solution
5056 would generate code for the action into an rtl sequence, and then
5057 splice in the exception-setup code if we later found we needed it.
5058 This has a few problems (for example it confuses the management
5059 of stack temporaries), and is ugly. Now that the compiler is 2-pass
5060 we have a cleaner solution: In pass 1, we remember which actions
5061 were followed by ON-handlers. In pass 2, we use this information
5062 to generate appropriate code before an action.
5063 * except.c (push_handler, pop_handler): In pass 1, set up data
5064 structures (global_handler_list) to remember if an action has an
5065 ON-handler. In pass 2, digest this information, and setup
5067 * except.c, actions.h (pop_handler): Take an extra int arg.
5068 * except.c (emit_setup_handler): New function, with code (moved
5069 from chill_start_on) to emit code before an action that has a handler.
5070 * except.c (except_init_pass_2): New function.
5071 * parse.y (pass1_2): Call except_init_pass_2 before pass 2.
5072 * parse.y (POP_UNUSED_ON_CONTEXT): Don't call pop_sequence.
5073 * parse.y: Invoke POP_UNUSED_ON_CONTEXT and POP_USED_ON_CONTEXT
5074 in pass 1 as well as pass 2.
5075 * parse.y (BEGIN ... END): Re-arrange logic to avoid block_stack
5076 (local to ../stmt.c) getting out of sync.
5077 * actions.c (push_action): Don't need to emit a NOP,
5078 now that we're no longer moving sequences around.
5079 * actions.c (push_action): Call push_handler even in pass one.
5081 Wed Feb 23 11:06:14 1994 Bill Cox (bill@rtl.cygnus.com)

5806 convert_float, convert_number): Set CH_DERIVED_FLAG for literals.
5807 * ch-expr.c (finish_chill_binary_op): Use convert_to_class.
5808 * ch-satisfy.c (safe_satisfy_decl): For CONST_DECL, make sure
5809 DECL_INITIAL gets set to result of convert.
5810 Also, clear CH_DERIVED_FLAG for SYN value.
5811 * expr.c (store_constructor): If a [power]set is exactly one
5812 word long, use single-word move.
5814 Sat Jan 8 08:38:29 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5816 * c-typeck.c (chill_initializer_constant_valid_p): Fix typo.

5820 * ch-typeck.c (build_chill_slice_with_length): Test that ARRAY is of
5821 ARRAY_TYPE before assuming so. Also, subtract 1 from LENGTH in
5822 computation of SLICE_END.

5826 * ch-expr.c (build_chill_indirect_ref): Handle MODE == NULL_TREE.
5828 * ch-expr.c (fold_set_expr): Handle OP1 == NULL_TREE (which happens
5829 for unary set operations).
5831 * ch-expr.c (build_chill_array_expr): Take new argument FORCE. All
5832 callers changed. All callers changed.
5834 * ch-convert.c (digest_structure_tuple): Handle SELECTED_VARIANT
5835 being NULL_TREE until we've started walking the list of values via
5836 the loop over VARIANTs.
5838 * ch-parse.y (build_chill_constructor): If we see an IDENTIFIER_NODE,
5839 treat it as an enum value (and hence constant). Also, only set
5840 TREE_STATIC if the constructor is indeed constant.
5841 * c-typeck.c (chill_initializer_constant_valid_p): If we see a
5842 VAR_DECL, test the TREE_CONSTANT field of the DECL_INITIAL, don't
5843 recurse on the DECL_INITIAL.
5845 Wed Jan 5 01:24:50 1994 Bill Cox (bill@cygnus.com)
5847 * Makefile.in: Add CHILL to LANGUAGES variable.
5848 * ch-actions.c (check_range): Call build_binary_op instead of
5849 fold, build to get the common types chosen.
5850 (cond_range_exception, cond_overflow_exception,
5851 cond_type_range_exception): Delete, obsolete.
5852 (chill_convert_for_assignment): Enable this, get particular
5853 about when to generate rangecheck code.
5854 * ch-expr.c (build_chill_function_call): Sketch in where to
5855 perform chill_convert_for_assignment on actual parameters.
5856 (build_chill_addr_expr): Correct compiler warning.
5857 * ch-loop.c (build_chill_iterator): Add runtime check for
5858 negative loop step expression.
5859 * ch-tree.h: Add prototype.
5860 * ch-typeck.c (chill_max_vary_array_ref): Correct misunderstanding.
5861 A varying array's length field counts the NUMBER of active array
5862 array entries, not the byte-length of them.
5864 Tue Jan 4 17:57:39 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5866 * ch-decl.c (do_decl): Call `suspend_momenary' if the
5867 converted constructor must live on the permanent_obstack.
5868 * ch-convert.c (convert): When building a new SET_TYPE
5869 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5870 * c-typeck.c (chill_initializer_constant_valid_p): Handle VAR_DECLs.
5872 * ch-typeck.c (chill_location): CONSTRUCTORS that are static

5875 on permanent_obstack if necessary.
5877 * ch-convert.c (digest_structure_tuple): When building a new SET_TYPE
5878 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5880 * ch-decl.c (do_decl): Fix handling of REFERENCE_TYPEs which
5881 the patch below helped to mess up.
5883 * ch-expr.c (build_chill_arrow_expr): Call `mark_addressable'.
5884 (build_chill_addr_expr): Take new argument ERRORMSG.
5885 All callers changed. Also, call `build_chill_addr_expr' where
5886 we used to call `build1 (ADDR_EXPR, ptr_type_node, ...)' since
5887 that now calls `mark_addressable' automagically.
5889 * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.
5890 This is needed because variables may appear in initialization
5891 statements, and their DECL_INITIALs are their values at
5892 initialization time.
5893 * ch-convert.c (digest_structure_tuple,digest_constructor): Changed
5894 to handle VAR_DECLs as initializers.
5896 * ch-convert.c (digest_structure_tuple): Copy elements of INITS so
5897 they aren't destroyed for later use.
5899 Tue Jan 4 15:25:30 1994 Bill Cox (bill@cygnus.com)
5901 * ch-expr.c (chill_expand_expr): Correct check-range lo_limit
5902 parameter for varying_array_ref calculations.
5903 (build_chill_indirect_ref): Prevent seg fault due to syntax error.

5905 of bogus error in votrics.
5906 (build_chill_slice_with_length): Change for debug tracability.

5910 * ch-convert.c (digest_structure_tuple): Fix phasing problem in
5911 handling variant record initializers.
5912 (various places): Change `pop_init_level' calls to match
5913 `push_init_level' wrt implicit variable.
5915 * ch-typeck.c (build_chill_slice): Convert the dynamic max index to
5916 `integer_type_node' before using it in comparisons. FIXME: should
5917 this be done in `chill_max_vary_array_index' by default?
5919 Tue Jan 4 00:24:14 1994 Bill Cox (bill@cygnus.com)
5921 * ch-actions.c: Fix comments.
5922 * ch-parse.y: Define caseaction_flag.
5923 (caseaction): Create new caseaction_flag node at the start,
5924 then free it at the end. Check it before the ELSE code.
5925 (expanded_case_label): Check the flag here. If set in either
5926 place, generate a jump to the end of the case.
5927 * ch-typeck.c (build_chill_slice_with_length,
5928 build_chill_slice_with_range): Add lots of compile-time
5929 parameter range checking.
5931 Mon Jan 3 21:49:04 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5933 * ch-convert.c (digest_structure_tuple): Call `push_init_level' with
5934 implicit==0 everywhere, not 1.
5935 (digest_constructor): Ditto.
5937 * ch-actions.c (check_range): Permit limits to be NULL_TREE.
5938 Also, hack out some dead code.
5939 * ch-typeck.c (build_chill_slice): Check varying and non-varying
5940 slice constructs for range failures.
5941 (build_chill_slice_with_range): Reindented, but not changed.
5943 * ch-typeck.c (chill_max_vary_array_index): New function.
5944 * ch-expr.c (chill_expand_expr): Call it.
5946 * ch-decl.c (var_data_id, var_length_id): New variables.
5947 (init_decl_processing): Initialize them. All calls to
5948 get_identifier (VAR_LENGTH or VAR_DATA) are now replaced
5949 by references to these variables. This simplifies the code
5950 w/o obscuring anything.
5952 Mon Jan 3 21:24:44 1994 Bill Cox (bill@cygnus.com)
5954 * c-typeck.c: Fix comment.
5955 * ch-actions.c (chill_expand_assignment): Error assigning to
5956 READONLY location. (PR_3903) Pass filename, linenumber
5957 to setbitpowerset runtime routine.
5958 * ch-decl.c (init_decl_processing): Add filename, linenumber
5959 parameters to setbitpowerset prototype.
5960 * ch-expr.c (build_chill_function_call): Error when passing a
5961 READonly location as a LOC or INOUT parameter.
5962 * ch-parse.y (mode): Correct code marking type as readonly.
5964 Mon Jan 3 19:03:55 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5966 * ch-actions.c (chill_expand_assignment): Disable code that defeats
5967 building varying array references.
5968 * ch-expr.c (chill_expand_expr): Add rangecheck code to
5969 VARY_ARRAY_REF case.
5970 * ch-typeck.c (build_chill_array_ref): Don't call an `expand_'
5971 function (in this case, `validate_varying_array_ref') when we're
5972 doing a `build_' operation.
5974 * ch-typeck.c (validate_varying_array_ref): Simplify interface
5975 since INDEX parameter can never meaningfully be an INDEXLIST.
5976 * ch-actions.c (expand_varying_length_assignment): Caller changed.
5978 Mon Jan 3 07:29:45 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5980 * ch-typeck.c (build_chill_cast): Set TREE_CONSTANT on NOP_EXPRs.
5981 * ch-convert.c (digest_structure_tuple): Switch to permanent_obstack
5982 if we need to build a CONSTRUCTOR for a SET_TYPE initializer.
5983 (digest_structure_tuple): If TREE_VALUE (VALUE) == NULL_TREE, don't
5984 call CH_COMPATIBLE or try to convert it to TREE_TYPE (FIELD). This
5985 can happen when constructors are output incrementally.
5986 * c-typeck.c (initializer_constant_valid_p): Handle SET_TYPEs.
5987 * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
5990 Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5992 * ch-convert (digest_structure_tuple): Handle SET_TYPEs. Also, call
5993 `convert' so we can handle INSTANCE types (and other anomolies)
5996 * ch-convert.c (digest_structure_tuple): Fixed variant
5997 structure initialization. Also fixed a typo (TYPE_NAME
5998 was being used on a FIELD_DECL instead of DECL_NAME).
5999 * c-typeck.c (initializer_constant_valid_p): Pass missing
6000 ENDTYPE argument on recursive call.
6001 (set_init_field): New function, needed by ch-convert.c change above.
6003 * ch-decl.c (layout_chill_variants): Added a FIXME next to an
6004 almost certain typo.
6006 * ch-expr.c (build_chill_arrow_expr): Call `build1' and set
6007 TREE_CONSTANT for static references.
6008 * ch-except.c (chill_start_on): Change calls to
6009 `build_unary_op' (which is C-specific) to `build_chill_arrow_expr'
6010 which has CHILL semantics.
6011 * ch-convert.c (convert): Ditto (albeit in some disabled code).
6013 Sat Jan 1 21:26:43 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6015 * ch-satisfy.c (safe_satisfy_decl): Reorder conditional test of
6016 TREE_CODE of DECL in case it's altered by actions in the switch.
6018 * ch-satisfy.c (satisfy): Undo abort added earlier on 1 Jan. CVS log
6019 mentions where to find code that triggers this case.
6021 * ch-actions.c (adjust_parm_or_field): Handle CONSTRUCTORS here as
6024 * ch-convert.c (digest_structure_tuple): Push to permanent_obstack if
6025 we're dealing with a CONSTRUCTOR that is TREE_PERMANENT.
6026 (digest_constructor): Ditto.
6028 Sat Jan 1 10:29:19 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6030 * ch-parse.y (handleraction,resultaction,assignaction,call): Modified
6031 so that CONSTRUCTORS are properly handled before being used.
6033 * ch-convert.c (chill_start_init): New function. All callers to
6034 `start_init' changed to call this function instead.
6035 (digest_struct_tuple): Defend against initialization machinery
6036 mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
6037 IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
6038 needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
6039 can be refered to throughout the compilation unit. Also remove an
6040 extraneous call to `process_init_element' erroneously added to the
6041 variant record sub-loop.
6042 (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
6043 CONSTRUCTORS of SET_TYPE.
6044 * ch-parse.y (build_chill_constructor): Refix typo. Also set
6045 TREE_STATIC if at top level.
6047 * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
6048 TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
6049 should have been called.
6051 * ch-convert.c (digest_struct_tuple): Restore code which tracks
6052 field initializations so that the compiler can deduce what variant
6053 initializations to assume.
6055 * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
6056 when we push into a scope that has a DECL with a CONSTRUCTOR as its
6059 * ch-parse.y (build_chill_constructor): Change the name of the
6060 parameter to something more meaningful. Fix typo. Also, handle case
6061 where element is an untyped CONSTRUCTOR.
6063 * ch-except.c (finish_handler_array): Set TREE_CONSTANT on
6064 constant ADDR_EXPRs.
6065 (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT
6066 on JBUF_REF (instead of calling `build1' which does not).
6068 * ch-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
6070 * ch-typeck.c (chill_expand_tuple): Deleted.
6071 * ch-parse.y (primval rule): Don't call `chill_expand_tuple';
6072 instead, use initialization machinery for CONSTRUCTORS that
6074 * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
6075 that are created here.
6076 * ch-satisfy (satisfy): Abort in case we would have called
6077 chill_expand_tuple. FIXME: some other code is needed here,
6078 but I don't know what yet.
6080 * ch-parse.y (build_chill_constructor): New function to
6081 propagate TREE_CONSTANT bits to CONSTRUCTORS.
6082 (untyped_expr rule): Use it.
6083 (primval rule): Use it.
6085 * ch-decl.c (do_decl): Call `finish_init'.
6086 * ch-convert.c (convert): If we spontaneously create a CONSTRUCTOR in
6087 this function, make sure the initialization machinery is set up.
6089 * ch-convert.c (digest_structure_tuple, digest_constructor): Add
6092 Fri Dec 31 11:31:01 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6094 * ch-grant.c (chill_finish_module_code): Mark ADDR_EXPR built by hand
6095 as being TREE_CONSTANT. Otherwise it gets bounded by the initializer
6098 * ch-decl.c (do_decl): Change in CONSTRUCTOR handling due to...
6099 * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
6100 rewritten to work with GCC's initialization code. The basic change
6101 was to keep the initializers in sync with the initialization
6102 machinery that `process_init_element' imposes. Both of these
6103 functions now return `void'.
6104 * ch-convert.c (convert): Changed calls to `digest_...' functions.
6106 FIXME: the code handling UNION_TYPE (and variant records) has not
6109 Fri Dec 31 15:32:56 1993 Bill Cox (bill@rtl.cygnus.com)
6111 * ch-lex.l (convert_number): Output the converted number if
6113 * ch-parse.y (signaldef): Set ignore_exprs correctly for a
6116 Fri Dec 31 13:17:48 1993 Bill Cox (bill@cygnus.com)
6118 * ch-parse.y: Cleanup handling of RETURN actions, to distinguish
6119 a RETURN without a value (which cannot have an exception
6120 handler) from a RETURN with a value (which can). Eliminate
6121 some shift/reduce and reduce/reduce conflicts.
6123 Thu Dec 30 17:42:32 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6125 * ch-inout.c (build_chill_writetext): Deal with 2 cases where
6126 types returned from `type_for_size' are not expected. FIXME.
6127 * ch-decl.c (init_decl_processing): Mark `char_type_node' unsigned.
6128 This is required when range checking is enabled.
6130 Thu Dec 30 14:28:25 1993 Bill Cox (bill@rtl.cygnus.com)
6132 DELAY CASE works now.
6133 * ch-decl.c (init_decl_processing): Move rest of tasking-related

6136 (optsetprio): New non-terminal.
6137 * ch-tasking.c (get_task_name): Delete, obsolete.

6144 correct its functioning.
6145 (build_delay_case_end): Correct the code.
6146 (tasking_init): Lots of tasking-related code moved here from
6147 init_decl_processing.

6153 failed full regression testing.
6154 * ch-lex.l (name_type_signal): Add debug output.
6155 * ch-parse.y (structured_variable): Add a debug variable.
6157 Wed Dec 29 02:05:51 1993 Bill Cox (bill@rtl.cygnus.com)
6159 * ch-decl.c (get_next_decl): Revert change which failed full
6162 Tue Dec 28 18:20:14 1993 Bill Cox (bill@rtl.cygnus.com)
6164 DELAY actions work now.
6165 * ch-decl.c: Correct spelling in comments.
6166 (get_next_decl): NULL out the decl's TREE_CHAIN before returning
6167 it, to prevent accidental access to the remembered_decls.
6168 (init_decl_processing): Add wait_event to runtime functions.
6169 * ch-expr.c (build_chill_indirect_ref): Prevent a syntax error from
6170 becoming a seg fault.
6171 * ch-grant.c: Correct a comment.
6172 * ch-loop.c: Delete/correct comments.
6173 * ch-parse.y (delaycaseaction): Add push/poplevel calls. Turn 'sorry'
6174 into rough draft of actual code.
6175 (delayaction): Don't make a new scope here, use get_unique_identifier
6177 (locdec): process event decls here, too.
6178 (mode): Add code to forbid READonly EVENT and BUFFER decls. Delete
6179 code which required EVENTs and BUFFERs to be declared at global scope.
6180 (simple_name_string): Add an EVENTNAME.
6181 * ch-satisfy.c (safe_satisfy_decl): Prevent a syntax error from
6182 becoming a seg fault.
6183 * ch-tasking.c (tasking_setup): Add the event queue's max. length
6184 as the 'entry_point' parameter in the list.

6186 calling runtime routine until we know whether we have a signal
6187 or a buffer to wait for.

6189 build_delay_case_label, build_delay_action,
6190 process_event_decls): Added functions.
6191 * ch-typeck.c (chill_similar): Allow all integers of differing
6192 precisions to be similar.

6196 * gcc.c (CHILL SPECS): Delete references to -M -MM -MD -MMD
6197 options. Delete C-specific defines. Disable piping from
6198 pre-processor to cc1chill (even if -pipe is specified), since cc1chill
6199 rewinds its input for its second pass. Piping still works
6200 from cc1chill to as.
6202 Thu Dec 23 12:31:55 1993 Bill Cox (bill@rtl.cygnus.com)
6204 * ch-tasking.c (decl_tasking_code_variable): Assure that the
6205 tasking_code variable is allocated on the permanent obstack.
6206 (tasking_setup): Lots of changes - handle EVENT/BUFFER max.
6207 queue length (passed as the entry_point parameter).
6208 Other changes to variable names to increase 'self-documentation'
6209 the only kind GNU CHILL will get, for a while..
6211 Wed Dec 22 10:46:31 1993 Bill Cox (bill@rtl.cygnus.com)
6213 * ch-decl.c (do_seize): Delete - it's unused. Fix comments.
6214 * ch-loop.c (build_chill_iterator): Convert BY expression
6215 so loop involving a SET works. Additional errors generated
6216 for numbered SET expression as start or end expression.
6217 * ch-tree.h: Prototypes for future DELAY functions.
6218 * ch-typeck.c: Standard indentation.
6220 Tue Dec 21 15:30:57 1993 Per Bothner (bothner@kalessin.cygnus.com)

6232 Also check that ranges have the same bounds.
6233 * ch-typeck.c (my_build_array_ref): Add optional range-checking.
6234 * ch-typeck.c (chill_location): Handle COMPOUND_EXPR properly.
6235 Return 2 if also a referable.
6236 * ch-typeck.c (chill_referable): Re-define to use chill_location.
6237 * ch-tree.h (CH_EQUIVALENT): Re-defined to use chill_equivalent.
6239 * dbxout.c (dbxout_type): Output the type attribute "@S;" to
6240 distinguish a string from a char array, and to distinguish a
6241 bitstring from regulat (power)set. (Needed for Chill.)
6242 * dbxout.c (dbxout_type): Only check for baseclasses in
6243 type.binfo is a vector. (It is used in Chill for tagged unions.)
6245 Fri Dec 17 09:56:07 1993 Bill Cox (bill@rtl.cygnus.com)
6247 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,

6260 the expressions in a STEP loop.
6261 * ch-tasking.c (rc_state): Add fields to flag SIGNAL and BUFFER

6265 * ch-tree.h: Fix prototypes.
6266 * ch-typeck.c (smash_dummy_type): Handle all four kinds of LANG_TYPE

6288 when a module has both GRANTs and SEIZE ALL.

7042 error message in pass 1.

7051 parameter to know whether to include an init expression.

7261 for example, as the module-level code's name.
7262 * ch-loop.c (build_temporary_variable, begin_for_range,
7263 init_loop_counter): Add parameter to decl_temp1 call.
7264 * ch-parse.y (quasi_signaldef): Clear quasi_signal flag here,

7314 * ch-parse.y (end_function): Use DECL_ARGUMENTS to check
7315 for parameterless process.
7317 Fri Oct 1 13:57:30 1993 Per Bothner (bothner@kalessin.cygnus.com)
7319 * ch-typeck.c (chill_location): New function.
7320 Based on lvalue_p, but also handle Chill-specific VARY_ARRAY_REF.
7321 * ch-typeck.c, ch-tree.h (CH_LOCATION_P), ch-convert.c: Use
7322 chill_location instead of lvalue_p.
7325 Fri Oct 1 11:28:42 1993 Bill Cox (bill@cygnus.com)
7327 * ch-convert.c (convert): Back out Michael's changes, unintentionally
7329 * ch-lex.l (handle_use_seizefile_directive): No longer downcase

7341 ch-convert.c (convert): Use it.
7342 * ch-typeck.c (build_chill_slice): Take length rather than upper
7343 bound. This makes it easier to recognize that A(X UP LENGTH)
7344 really has fixed length. Also, if the argument is string,
7345 mark the slice as a string too. Also, handle varying strings.
7347 * ch-typeck.c (conflate_singleton_strings): New global.
7348 * ch-typeck.c (chill_similar): If conflate_singleton_strings is
7349 set (as it currently is), allow CHARS(1)/BOOLS(1) to be similar
7350 to CHAR/BOOL, as required by the 1984 version of Z.200.
7351 * ch-convert.c (convert_to_char): Convert CHARS(1) to CHAR.
7352 * ch-convert.c ( build_array_type_for_scalar): If input is string,
7354 * ch-convert (maybe_turn_scalar_into_arra), ch-tree.h: Removed.
7355 * ch-convert.c (convert): Convert CHAR to CHARS(1).
7357 This fixes 'X // := Y' and is also a general simplification.
7358 * ch-actions.c (chill_expand_assignment): Convert 'LHS OP := RHS'
7359 to 'LHS := LHS OP RHS' (using stabilize_reference on LHS).
7360 Also, call save_expr on RHS if a multiple assignment.
7361 * ch-parse.y (assignaction): Therefore, no longer need to call
7362 stabilize_reference on RHS.
7363 * ch-typeck.c (build_chill_modify_expr), ch-tree.h: Remove
7364 modifycode parameter. Make it the caller's responsibility to
7365 handle <assigning operator>.
7366 * ch-actions.c, ch-decl.c, ch-except.c, ch-expr.c, ch-grant.c,
7367 ch-loop.c: Fix calls to build_chill_modify_expr accordingly.
7369 Wed Sep 29 18:02:55 1993 Per Bothner (bothner@kalessin.cygnus.com)
7371 * ch-lang.c (string_index_type_dummy), ch-tree.h: New variable.
7372 * ch-decl.c (integer_minus_one_node), ch-tree.h: New variable.
7374 * ch-parse.y (arrayindex: modename): Remove useless code.
7375 * ch-satisfy.c (satisfy): Don't gag on string_index_type_dummy,
7376 * ch-tree.c (build_string_type): Pass string_index_type_dummy as
7377 the parent type of the index range.
7378 * ch-typeck.c (layout_chill_range_type): Recognize and handle
7379 string_index_type_dummy - specifically allow an empty range.
7381 Wed Sep 29 13:36:23 1993 1993 Bill Cox (bill@cygnus.com)
7383 * ch-convert.c (convert_to_reference): Check for loc-identity
7384 mismatches correctly (and remove one of those chill_compatible
7386 * ch-decl.c (decl_tasking_code_var): New function, called from
7387 push_extern_process and push_extern_signal.
7388 * ch-parse.y (end_function): Delete parameter. Check current_function_decl
7389 whether it's actually a process, and whether it has parameters.
7390 Make Michael's change simplifying the pass 2 test, preventing a seg
7392 (procedure, process): Change calls to end_function, remove
7393 code saving value from build_process_header. Delete redundant chill_
7394 phrases from some function calls.
7395 * ch-tasking.c: Remove some redundant _chill phrases from function
7397 * ch-tree.h: Remove some redundant _chill phrases from function
7398 names. Add the CH_VARYING_ARRAY_TYPE macro, call it from
7399 all relevant places.
7400 * ch-typeck.c: Use the new macro. Cast TREE_CODEs to chill_tree_code.
7402 Wed Sep 29 13:07:43 1993 Per Bothner (bothner@kalessin.cygnus.com)
7404 * ch-convert.c (convert_to_reference): Remove redundancies.

7406 with a recursive convert call.
7407 * ch-decl.c (do_decl): Add missing compatibility-checking
7408 of initializer (don't depend on convert).
7410 Tue Sep 28 00:02:25 1993 Per Bothner (bothner@kalessin.cygnus.com)
7412 * ch-tree.h (CH_LOCATION_P): New macro.
7413 * ch-typeck.c (layout_chill_range_type): Fix call to
7414 type_for_size, when figuring out a defaulted parent type.
7415 * ch-expr.c (build_chill_lower, build_chill_sizeof): Check
7416 for TREE_CODE_CLASS != 't' rather than == 'd'.
7417 * ch-expr.c (build_chill_function_call): Use CH_LOCATION_P
7418 to check for location, rather than TYPE_CODE_CLASS == 'd'.
7420 * ch-tree.c (build_string_type): Make 2-pass safe. Also,
7421 change parameter to be length, not index type.
7422 * ch-parse.y (mode2), ch-expr.c (build_concat_expr), ch-lex.l
7423 (build_chill_string): Modify callers of build_string_type accordingly.
7424 * ch-lex.l (check_newline): Don't look for # directive inside a
7426 * ch-grant.c (grant_array_type): Make more robust for char-
7427 and bit-strings (allow non-constant sizes). Change parameters
7428 and return types. (raw_decode_mode): Use grant_array_type
7429 for bitstrings. (otherwise): Fix grant_array_type callers.
7431 Mon Sep 27 16:57:57 1993 Per Bothner (bothner@kalessin.cygnus.com)
7433 Remove changes of Sep 15.
7434 * ch-tree.h (CH_SINGLETON_DOMAIN): Removed.
7435 * ch-typeck.c (chill_similar): Don't allow a singleton
7436 powerset to be similar to its domain.
7437 * ch-convert.c (convert_to_boolean): Don't convert a singleton
7438 SET_TYPE constructor to a Boolean.
7440 * ch-actions.c (chill_expand_assignment): Handle IN_EXPR on
7441 LHS of assignment, which is what we're current (temporarily?) using.
7443 Mon Sep 27 06:01:57 1993 Bill Cox (bill@rtl.cygnus.com)
7445 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
7446 ch-grant.c, ch-inout.c, ch-parse.y, ch-satisfy.c,
7447 ch-tasking.c, ch-tree.c, ch-tree.h, ch-typeck.c:
7448 -Wall cleanup. Add prototypes where missing.
7449 Delete unused variables. Cast uses of tree_codes
7450 to chill_tree_code, which they are.
7452 Sun Sep 26 13:09:57 1993 Bill Cox (bill@rtl.cygnus.com)
7454 * ch-decl.c (do_decl): Save initializer in pass zero
7456 * ch-lex.l: Fix comments, indentation.
7457 * ch-parse.y: Standardize error messages to use
7458 uppercase for CHILL keywords rather than quoting them.
7459 Suggestion from docs department.
7460 * ch-tasking.c: Pervasive changes to get processes to
7462 * ch-tree.h: Delete prototypes for functions whic
7463 I made static inside ch-tasking.c.
7465 Sun Sep 26 02:40:02 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7467 * ch-lex.l (yywrap): Call `check_newline' in case the file
7468 started with a line directive.
7470 Sat Sep 25 13:54:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
7472 * ch-decl.c: Expand pre-amble comment.
7473 * ch-decl.c (struct scope, push_module): Use new field
7474 tail_chain_module to build child-module list in order.
7475 (Just to make compiler debugging a little less confusing.)
7477 * ch-decl.c (struct scope): New field weak_decls.
7478 * ch-decl.c (find_implied_types): New interface. Now pre-pend
7479 new enum types to a given input list. This makes it easier to
7480 avoid duplicates, which should at least be more efficient.
7481 Also, handle FUNCTION_DECL.
7482 * ch-decl.c (bind_saved_names): Removed. Distribute its
7483 functionality over new functions (push_scope_decls, pop_scope_decls,
7484 build_implied_names, bind_sub_modules). The goal (which seems to
7485 have been more-or-less attained) was to fix weak name handling.
7486 * ch-decl.c (poplevel): Use new function pop_scope_decls.
7488 * ch-tasking.c (build_signal_struct, build_tasking_message_type):
7489 Use build_decl directly, rather than grok_chill_fixedfields
7490 (which depends on ignore_exprs and has more overhead).
7491 * ch-tasking.c (build_signal_struct): Construct the type
7493 * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
7494 than build_array_ref (which does C-specific "optimizations").
7495 (Hence move my_build_array_ref up earlier in the file.)
7497 Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7499 * ch-tasking.c: Declare static variable `void_ftype_void'.
7500 (chill_tasking_init): Initialize `void_ftype_void' here.
7501 (build_tasking_struct): Use, don't declare `void_ftype_void'.
7502 (generate_tasking_code_variable): Call `do_decl', not
7503 `decl_temp1' to declare TASKING_CODE_NAME.
7504 (tasking_setup): Drop into 1-pass mode so that all
7505 tasking-related declarations are installed in the global
7506 scope. Use correct CHILL types for initializers (since
7507 ptr_type_node doesn't have the right meaning for CHILL).
7508 Also, call `do_decl' instead of `decl_temp1' for
7510 (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
7511 `chill_finish_compile' in sync between passes.
7513 * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
7514 declarations on pass zero. Keep obstacks in sync, and always
7515 call `finish_decl' for pass zero declarations.
7516 (push_chill_extern_function): Keep obstacks in sync, and always
7517 call `finish_decl' for pass zero declarations.
7518 (build_enumerator): Ditto.
7519 (grok_chill_variantdefs): Change PASS test to exclude only
7521 (finish_struct): Ditto.
7522 * ch-expr.c (build_chill_component_ref): Ditto.
7523 (build_chill_binary_op): Ditto.
7524 * ch-tree.c (build_powerset_type): Ditto.
7525 (build_bitstring_type): Ditto.
7526 * ch-typeck.c (build_chill_range_type): Ditto.
7527 (build_chill_struct_type): Ditto.
7529 * ch-decl.c (build_chill_exception_decl): Clarify reasons for
7530 extra pushing and popping of obstacks.
7532 * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
7533 on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
7535 * ch-grant.c (chill_finish_compile): Clear out both
7536 MODULE_INIT_LIST and TASKING_LIST if either contains stuff
7539 * ch-parse.y (rccase_label): Add NAME rules so that pass one
7540 works w/o knowing we're parsing a signal. Simplify SIGNALNAME
7541 rules since we only get SIGNALNAME tokens in pass two.
7542 (sendaction): Ditto.
7543 * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
7544 BUFFERNAME on pass two. The grammar now handles this.
7545 * ch-decl.c (lookup_remembered_decl): Deleted.
7547 Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
7549 * ch-decl.c (lookup_remembered_names): Removed. It was being
7550 misused in ch-lex.l.
7551 * ch-lex.l (name_type_signal): Revert last change. Basically,
7552 we cannot use the C typedef/variable name trick in CHILL, due
7553 due to the language's 2-pass nature.
7554 * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
7556 * ch-tree.h (lookup_remembered_name): Comment out the prototype.
7558 Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7560 * ch-decl.c (do_decl, push_chill_extern_function): Change pass
7561 checks so the pass == 0 case is handled for built-in types.
7562 (push_modedef): Add check for error_mark_node.
7563 (lookup_remembered_decl): New function.
7564 (pushlevel, poplevel) Change pass checks.
7565 (pushdecl): Check type as well for NULL.
7566 (build_enumerator): Handle pass == 0 case.
7567 * ch-lex.l: Use lookup_remembered_decl to get lastiddecl
7569 * ch-parse.y: Set pass to zero to indicate initial decl processing.
7570 Replace NAME references with SIGNALNAME references.
7571 (startaction): Only check copy number if not ignoring actions.
7572 Always call build_chill_start_process.
7573 (optstartset): Don't lookup the instance name.
7574 * ch-tasking.c (generate_tasking_code_variable): Replace
7575 do_decl call with decl_temp1 call.
7576 (build_chill_start_action): Check for ignore_actions here.
7577 (build_tasking_message_type): Layout the type.
7578 (rc_state_type): New structure to keep nested receive-case
7580 (build_chill_receive_case_start, build_chill_receive_case_end):
7584 Fri Sep 24 04:19:15 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7586 * ch-tasking.c (build_chill_receive_case_start): `namedecl'
7587 should be a _DECL, not an IDENTIFIER_NODE.

7610 ALIAS_DECL the name in the most recent use_seize_file directive.
7611 (This requires that use_seize_file directives written to the
7612 grant file be written before the SEIZEs that need it.)
7613 Allow clashing declarations granted into the global scope
7614 (produce a warning), but remember the seizefile case from
7615 (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
7616 The a SEIZE will select the granted decl that matches its
7617 DECL_SEIZEFILE (in other words: grants from the most recent
7618 use_seize_file will be preferred).

7627 Don't call grant_use_seizefile.
7628 * ch-lex.l (mark_use_seizefile_written): New function.

7946 ch-expr.c (finish_chill_binary_op): For now, prefer IN_EXPR
7947 over BIT_FIELD_REF because of various problems with BIT_FIELD_REF
7948 (incomplete support for variable fields, and possible bug in

7993 * ch-lex.l (build_chill_string): Make string type be derived

8012 * ch-except.c (finish_handler_array), ch-decl.c (finish_decl):
8013 Don't use store_init_value, since it calls digest_init instead
8014 of chill_digest_init.

10275 (modedefinition): Use new push_modedef function.
10276 * ch-parse.y (modedefinition): Don't depend on inherited
10277 attributes (- implemented incorrectly!): Use a global variable

10306 (start state 'ccitt'): Deleted, unused. Moved unused, but reserved,
10307 tokens to NORMAL state.
10308 (compiler_directive): Replaced by equal_number. Now the only
10309 recursive call to yylex happens in check_newline at the beginning
10312 Sat Apr 10 09:55:50 1993 Bill Cox (bill@rtl.cygnus.com)
10314 * ch-actions.c (build_chill_case_expr): Added from ch-parse.y.
10315 * ch-lex.l (ENTRY, PERVASIVE, ROW, STEP): Add token recognition to
10317 * ch-parse.y (case_expr): Move code into ch-actions.c. There will

10320 * ch-tree.h (build_chill_case_expr): Add prototype.
10321 * ch-typeck.c (build_chill_cast): Allow untyped_expr - just assign the
10322 type to the expr. Check for CASE_EXPR, call expand_case_expr.
10324 Sat Apr 10 01:10:51 1993 Per Bothner (bothner@rtl.cygnus.com)
10326 * ch-parse,y (in_pseudo_module): New variable. Try if we're
10327 in a seizefile, but not in a module nested in the seizefile.
10328 Use for backwards compatibility with old grantfiles.
10329 * ch-decl.c (do_decls, push_syndecls, push_newmode, push_synmode):
10330 If in_pseudo_module, grant new declaration.

10340 * ch-lex.l: Re-write to use start states, to avoid calling
10341 yylex() recursively.
10342 * ch-lex.l (compiler_directive); This is now obsolste. FIXME.
10343 * ch-lex.l: Call push_module and pop_module when reading a
10344 seizefile. This creates a pseudo-module.
10345 * ch-parse.y: Clean up handling of empty declarations and
10346 action statements; semicolons are now optional a number of
10348 * ch-parse.y: Remove some bogus tests for "statement
10349 out of sequence" (they're both legal and work).
10350 * varasm.c (mak_function_rtl): Remove kludge that may
10351 not be necessary (and loses anyway).
10353 Fri Apr 9 09:37:38 1993 Bill Cox (bill@rtl.cygnus.com)
10355 * ch-expr.c (chill_expand_array_assignment): Remove false error about

10372 which is the list (in order) of decls in the module.
10373 Don't reverse the getdecls() list; that is handled by caller.
10374 * ch-grant.c (chill_grant): Test that a declaration is
10375 visible before writing it.
10376 * ch-parse.y (push_module): Make sure to hide declarations
10377 from surrounding module.
10378 * ch-parse.y (pop_module): Restore those declarations.

10391 assignment, clean up.
10392 * ch-typeck.c: Add prototype for require_complete_type.

10402 * ch-decl.c (massage_param_node): New function.
10403 It handles the LOC/IN/OUT/INOUT parameter distinction,
10404 as well as calling build_chill_array_parm_type if needed.
10405 * ch-tree.h (massage_param_node): New prototype.
10406 * ch-decl.c (push_parms): Use new massage_param_node().
10407 * ch-parse.y (pmodearg): Use new massage_param_node().
10408 * ch-parse.y (formpar): Don't call build_chill_array_parm_type;
10409 now handled by massage_param_node.
10410 * ch-typeck.c (my_build_array_ref): Handle non-zero array
10412 * ch-actions.c (build_chill_function_call): If the formal

10416 the pseudo struct type is allocated on the permanent_obstack.
10417 * ch-parse.y (location): Remove thinko.
10418 * ch-actions.c (chill_comptypes): Comment out test for

10431 Mon Apr 5 19:56:56 1993 Bill Cox (bill@rtl.cygnus.com)
10433 * ch-actions.c, ch-decl.c: Use tree_int_cst_equal and integer_zerop

10453 Fri Apr 2 21:55:14 1993 Per Bothner (bothner@rtl.cygnus.com)
10455 Major re-write of New module/seize/grant stuff.
10456 Now, a grantfile is a spec module and contains all the
10457 top-level declarations of the granting module, not just
10458 those that are granted. It also contains explicit grant
10459 statments naming those declared names that are granted.
10460 It also has seize statements and use_seize_file directives
10461 to correctly handle transitive dependencies.
10463 * ch-parse.y: Change to allow multiple modules per source file.
10464 Allow spec modules (including quasi definitions) as well as
10466 Allow spec modules inside normal modules; these behave as if
10467 they were outermost. This violates the Blue Book, but is
10468 needed by the new grantfile mechanism. (A grant file is a
10469 spec module that gets included by the use_seize_file directive.)
10470 * ch-parse.y (struct module *current_module, push_module,
10471 pop_module): Support module nesting (for spec modules only).
10473 * ch-tree.h (struct module): New.
10474 * ch-grant.c (granted_decls): New list of declarations
10475 that have been granted into the outermode pseudo-module.
10476 * ch-grant.c (decode_mode): If the decl has a name,
10477 always write the name, not just if the decl has already
10478 been written. Since we write out all decls, we can assume
10479 it will be written later, and depend on the forward
10480 declaration kludges to catch it.
10481 * ch-grant.c (decode_decl): Don't write out _EXTERN.
10482 Instead write out standard (Blue Book) quasi-definitions.
10483 * ch-grant.c (push_granted): New function.
10484 * ch-grant.c (seize_implied_names): New function. Re-write
10485 how set element names are seized when a set type is seized.
10486 * ch-grant.c (chill_seize): Work by seraching the
10487 granted_decls list and copying the declaration.
10488 * ch-grant.c (chill_grant): Write all declarations
10489 declared in this module. Write GRANT statements for
10490 those granted. seize statements for decls seized from
10491 other modules. Write extra syntax to make a complete
10493 * ch-grant.c (grant_use_seizefile): Copy use_seize_file
10494 directives into grant file.
10495 * ch-lex.l (setup_seizefile_read): Call grant_use_seizefile.
10497 * ch-lex.l (struct input_state, current_input_state,
10498 push_input_file, pop_input_file): New (type, variable,
10499 function*2). Used to save and restore state on an input file.
10500 * ch-lex.l: Clean up to handle nested input seizefiles
10501 (needed by new grant/seize mechanism.
10502 * ch-lex.l (skip_to_end_of_directive): New function.
10503 * ch-lex.l (compiler_directive: USE_SEIZE_FILE): Make sure
10504 we skip to the end of the directive *before* we switch
10506 * ch-lex.l (setup_seizefile_read): Prevent reading the
10507 same seizefile twice (otherwise likely with new grant/seize).
10508 * ch-lex.l: Recognize SPEC. Misc cleanups.
10510 * ch-parse.y: Fixed foreward references of types.
10511 Removed the unknown_type_node crock.
10512 * ch-decl.c: Remove all uses of unknown_type_node.
10513 Check for TYPE_SIZE zero instead.
10514 * ch-decl.c (fixup_unknown_type): Make sure new mode
10515 gets copied into old mode. Merge their variant chains.
10516 * c-decl.c (lookup_name_current_level): Make non-static.
10517 * ch-decl.c (lookup_name_current_level): No longer needed.
10519 * ch-parse.y (call): Allow an implicitly defined function
10520 name following the CALL keyword.
10521 * ch-tree.h (struct lang_identifier): Add implicit_decl,
10522 and make sure order of fields matches c-tree.h.
10524 * ch-actions.c (lang_init, build_allocate_memory_call,
10525 build_allocate_globals_memory_call): Fix names (add initial '_')
10526 and prototypes of _allocate_[global_]memory (2nd param is ref).
10527 Use build_chill_function_call, not build_function_call,
10528 so the reference parameter gets handled.
10529 * ch-actions.c. (lang_init): Make sure boolean_{true,false}_node
10530 have boolean_type_node as their types.
10531 * ch-actions.c (build_chill_lower, build_chill_upper): Fix to
10532 work for arrays with BOOLEAN_TYPE ranges (and simplify some).
10534 * ch-except.c: Make sure an end_label is generated,
10535 and jump to it if there is no exception.
10537 * ch-convert.c (convert_to_reference): Strip off NOP_EXPR casts.
10538 * expr.c (expand_expr): Handle NOP_EXPR as Chill-style casts.
10539 (Need cleaning up and FSF installation!)
10540 * ch-parse.y: If taking the address of a cast, move the
10541 ADDR_EXPR inside the NOP_EXPR.
10543 * ch-typeck.c (my_build_array_ref): Simplified, more suitable
10544 versions of build_array_ref from c-decl.c. (E.g. don't barf
10545 if index type is char or bool.)
10546 * ch-typeck.c (build_chill_array_ref): Use my_build_array-ref.
10548 * ch-typech.c (build_chill_bin_type): New function.
10549 Support BIN(N) range type specification.
10550 * ch-parse.y (mode2), ch-lex.l: Recognize BIN(N).
10552 * ch-tree.h (CH_SIMILAR): Redefine in terms of chill_similar.
10553 * ch-typeck.c (chill_similar): New function. Recognize that
10554 that range types are similar to their parent types.
10556 * ch-tree.h: Declare flag_local_loop_counter.
10557 * ch-loop.c: Whether the loop variable is local to the loop
10558 in now controlled by flag_local_loop_counter, instead of
10559 #ifdef'd on CREATE_SCOPE.
10560 * ch-actions.c (lang_decode_option): Recognize flags
10561 "-f[no-]local-loop-counter".
10562 * toplev.c (lang_options): Add Chill flags -f[no-]local-loop-counter.
10564 * varasm.c (make_function_rtl): Due to problems with forward
10565 references, don't rename nested functions in Chill. (Kudge!)
10567 Sun Mar 28 10:12:45 1993 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10569 * ch-lex.l (push_back, readstring): Fix prototypes.
10571 Fri Mar 26 18:32:15 1993 Bill Cox (bill@rtl.cygnus.com)
10573 * ch-parse.y: Put %type directives back into alpha order.
10574 (variant_alternative): Simplify error_mark test.
10575 (variantfields, varianthack): Add error_mark checks.

10579 * ch-lex.l (convert_charliteral): Rewrite to avoid bogus error msg.
10580 * ch-parse.y (get_type_of): Add function to deal with possible fwd
10581 declared type name. Call it from lotsa places. Add lotsa checks
10582 for error_mark_node. Standardize indentations.
10584 Thu Mar 25 15:00:11 1993 Bill Cox (bill@rtl.cygnus.com)
10586 * ch-expr.c (chill_expand_assignment): Avoid seg fault while checking
10587 for array assignments.
10588 * ch-parse.y (action): Add recognition for allocate_memory and
10589 allocate_global_memory system calls.
10590 (mode2): Remove ill-conceived error check that broke REFs to
10591 as-yet-undeclared types. Check for IDENTIFIER_NODE, lookup its
10592 DECL if there, pass TREE_TYPE of decl to build_pointer_type.
10593 (variantfields, varianthack): Clean up.
10594 (variantfield): Check for IDENTIFIER_NODE, lookup its DECL if
10595 there, pass TREE_TYPE of decl to grok_fixedfields.
10596 (labellist): Explicitly assign error_mark_node to signal error.
10597 * ch-typeck.c (chill_compatible): Report FALSE for bad parameters,
10598 rather than seg faulting.
10600 Thu Mar 25 10:35:58 1993 Bill Cox (bill@rtl.cygnus.com)
10602 * ch-actions.c (lang_init): build_function_type for allocate_memory
10603 and allocate_global_memory runtime routines. Move discrete_type_p
10605 * ch-typeck.c (discrete_type_p): Move here, where it belongs, call it

10627 Mon Mar 22 12:42:58 1993 Per Bothner (bothner@rtl.cygnus.com)
10629 * ch-except.c (start_handler_array): Make sure the handler
10630 array and its type get on the permanent obstack.
10631 * ch-grant.c (write_grant_file): Don't write the _INIT=name
10632 specifier: It isn't needed, and loses (because of funny
10633 characters in the chill_initializer_name).
10634 * ch-decl.c (push_synmode): Set TYPE_NAME(mode) = syndecl.
10635 * ch-lang.c (finish_chill_enum): Don't allocate a dummy
10636 TYPE_DECL for the enum. I don't think it is needed (?),
10637 and removing it is needed for the change above.
10639 * ch-grant.c (grant_array_type, decode_mode): Remove unused
10641 * ch-grant.ch (raw_decode_mode): New function, based on old
10643 * ch-grant.c (decode_mode); This is now just a wrapper around
10644 raw-decode_mode - but does not call raw_decode_mode if the
10645 type is named and has already been emitted.
10647 Fri Mar 19 11:55:35 1993 Bill Cox (bill@rtl.cygnus.com)
10649 * ch-actions.c: Add prototypes, remove unused variables. Attempt to
10650 continue generating grant file in presence of error (Wilfried's
10651 patch to lang_finish).
10652 * ch-expr.c: Change assign_stack_temp calls so temps get recovered
10653 after each statement. Move convert call into
10654 chill_expand_assignment from ch-parse.y.
10655 * ch-grant.c: Generally re-order, clean up. Include Per's decode_mode
10656 simplification. Include commented-out hack in decode_mode to return
10657 type's name if type SEIZEd or already GRANTed in this file.
10658 * ch-lex.l: Add prototypes.
10659 * ch-parse.y (assignaction): Move convert call into
10660 chill_expand_assignment.

10673 * ch-parse.y (structured_variable): Return NULL_TREE is invalid WITH
10674 parameter is seen, don't count it in structured_variable_list. Pre-
10675 vents seg fault when only WITH operand is invalid.
10676 * ch-parse.y (label_spec): Correct assignment within IF expression which
10677 was intended to be equality test. Remove unused variables.
10678 * ch-tree.h: Add prototype. Remove unused EXCP_CODE enumeration, and
10679 prototyping editorial comments.
10680 * ch-typeck.c: Disable generation of code to validate array index for
10681 now. Should be done as a call-back from more generic array_ref code.
10682 Clean up parameter checking. Remove unused variables.
10684 Fri Mar 12 11:57:32 1993 Bill Cox (bill@rtl.cygnus.com)
10686 * ch-actions.c (chill_varying_type_p): Return FALSE if given NULL type.

10804 * expr.c (expand_expr): Use actual library name for __inpowerset
10806 * stor-layout.c (variable_size): Disable complaint about variable-

10819 remove handling of CHAR arrays - they're handled in build_char_array_expr.

10821 need bitcount instead.

10823 version that does stuff we don't want.

10830 build_chill_length: Move VARYING array handling before regular char
10832 * ch-expr.c chill_expand_expr: Disable concatenate code - we need to
10833 the VARYING status of the target to do this correctly. Use powersetlen
10834 for the powerset operations, not a byte length.
10835 * ch-loop.c: Make CREATE_SCOPE #define to enable creation of a new scope
10836 for each CHILL loop, as Z.200 requires. Add powerset and error flags
10837 to loop structure. Evaluate user's powerset expression into a temp,
10838 scan it destructively with __ffsetclrpowerset or __flsetclrpowerset
10839 for powerset loop. Only do loop-end assignments if NOT a powerset
10840 loop, which has much less overhead now.

11072 * ch-typeck.c (convert): Avoid needlessly (and lossingly) calling

11108 types such as bitsets.
11109 * ch-tree.c (build_bitstring_type): Set TYPE_MIN_VALUE

11113 * ch-tree.h, ch-actions.c (lang_init), ch-grant.c (decode_mode):

11116 New types chill_integer_type_node and chill_unsigned_type_node
11117 that correspond to the Chill source types INT and UINT.
11118 For now, these match the C 'short' types, but that should
11119 become a configuration option later,

11141 * ch-tree.def: add a new tree type - just for varying array
11142 references. We were using ARRAY_REF, but the underlying C
11143 code also generates that one.

11438 * chill.gperf, ch-hash.h: add Wilfried's tokens
11439 * ch-lex.l: fold in Wilfried's changes. Some tokens

11520 * ch-expr.c: use macros for varying struct names. Simplify
11521 chill_expand_array_assignment.

11560 initializer name follows the standard 'collect' convention,
11561 don't need to call assembler_constructor_alias, but can
11562 use the standard assemble_constructor instead.

11565 * ch-parse.y: Move code that is common to the beginning of

11608 * ch-hash.h, chill.gperf: cleanup. fewer keywords seen by ch-parse.y.
11610 Sat Jan 2 13:27:49 1993 Per Bothner (bothner@rtl.cygnus.com)
11612 * ch-lex.l (check_newline): Use the orginal versions (derived
11613 from the C code, not the simplified, special-case version).
11614 Also, fix that version of check_newline to not call yylex()
11616 * ch-lex.l (yy_input): Call check_newline to handle
11617 newlines and check for # directives.
11618 * ch-lex.l (syntax): Don't recognize #-directives; these
11619 are now handled by check_newline.
11620 * ch-actions.c (lang_init): Call the modified version of
11621 check_newline(). Do this at the *after* we've initialized
11622 standard types, so this can be done while lineno is still 0.
11624 Sat Jan 2 10:57:20 1993 Bill Cox (bill@cygnus.com)
11626 * ch-hash.h, chill.gperf: add remaining reserved words.
11628 Sat Jan 2 09:59:55 1993 Bill Cox (bill@cygnus.com)
11630 * ch-tree.h, ch-parse.y, ch-lex.l: add remaining reserved words,
11631 names for exceptions
11633 Fri Jan 1 12:30:31 1993 Fred Fish (fnf@cygnus.com)
11635 * ch-tree.h (JOINER): Define joiner character the same way
11637 * ch-grant.c (chill_start_module_code): Use JOINER character
11638 to implement name mangling for the initializer function name.
11639 Algorithm is designed to be simple, distinct from C++ mangled
11640 symbols, and easy to convert to demangled form.
11642 Thu Dec 31 10:30:51 1992 Bill Cox (bill@rtl.cygnus.com)
11644 * ch-expr.c: make array assignments work with indirect refs.
11645 * ch-actions.c: prepare for array parameter handling.
11646 * ch-loop.c, ch-parse.y, ch-tree.def, ch-typeck.c: clean up.
11648 Thu Dec 31 15:29:20 1992 Per Bothner (bothner@rtl.cygnus.com)
11650 * ch-lex.l (yy_input): Re-write to return more than one
11651 character at a time (execpt when reading seize-files).
11652 Don't increment lineno until we start reading the next line.
11653 This fixes some off-by-one errors in lineno.
11655 Wed Dec 30 16:15:23 1992 Per Bothner (bothner@rtl.cygnus.com)
11657 * ch-convert.c: Assume use of new common.c.
11658 * ch-convert.c (convert_to_reference, convert_from_reference):
11659 New routines, to handle loc-identity declared variables and
11660 LOC parameters (both of which are implemented as references).
11661 * ch-lang.c (convert_to_boolean, convert_to_char): Move to
11662 ch-convert.c, where they would seem to belong.
11663 * ch-convert.c (convert): New function, since we no longer
11664 link in c-convert.c.
11665 * ch-expr.c (chill_expand_assignment): Handle by calling
11666 convert() instead of chill_comptypes().
11667 Also handle the LHS being a reference.
11668 * ch-parse.y: Add a procedure call as an action.
11669 * ch-parse.y (locdec, optlocinit): Move handling of
11670 loc-identity declarations from optlocinit to locdec
11671 - and add working semantics for it.
11672 * ch-parse.y (seizestatement, visibilty_stmt): Simplify.
11673 * ch-parse.y (grantstatement etc): Don't bother making list.
11674 * ch-lex.l: #include <sys/types.h> before <sys/stat.h>.

11678 * ch-parse.y, ch-expr.c: add support for declaring & assigning
11680 * ch-typeck.c: allow VARYING structures in assign_type_to_expr.
11682 Tue Dec 29 15:28:48 1992 Bill Cox (bill@cygnus.com)
11684 * ch-actions.c: implement expressions of arrays of char,
11685 ( concatenation, relationals ), correct type of code parameters
11686 * ch-expr.c: correct type of code parameters
11688 Tue Dec 29 11:16:19 1992 Bill Cox (bill@cygnus.com)
11690 * ch-decl.c: cleanup.
11691 * ch-parse.y: put emit_line_note() calls in lotsa places,
11692 per Fred's request; be sure that statements get counted also.
11693 * ch-lex.l: standardize function headers.
11695 Tue Dec 29 10:41:56 1992 Fred Fish (fnf@cygnus.com)
11697 * ch-decl.c (start_chill_function): Always return 1, rather
11698 than a random value.
11699 * ch-lex.l (check_newline): Add a version for chill that
11700 just snarfs the right value for main_input_filename out of
11701 the first line of the input file, without disturbing the
11702 lexer state or requiring it's assistance.
11703 * ch-actions.c (lang_init): Call check_newline, like the
11704 other language frontends, to get main_input_filename set
11705 from first line of input file.
11707 Mon Dec 28 18:49:01 1992 Bill Cox (bill@cygnus.com)
11709 * ch-parse.y: clean up conflicts. The remaining one is

11715 clean up some parser conflicts.
11717 Mon Dec 28 15:00:20 1992 Bill Cox (bill@cygnus.com)
11719 * ch-parse.y, ch-lex.l: add keywords and parsing for most of
11722 Sat Dec 26 20:48:23 1992 Fred Fish (fnf@cygnus.com)
11724 * chillrt/chillrt0.c: Oops, SVR4 doesn't need leading '_'
11725 on build_exceptions.
11727 Sat Dec 26 11:00:36 1992 Fred Fish (fnf@cygnus.com)
11729 * ch-grant.c (chill_finish_module_code): Call
11730 assemble_constructor_alias rather than assemble_constructor.
11731 * varasm.c (assemble_constructor_alias): New function,
11732 like assemble_constructor, but also handles the case where
11733 ASM_OUTPUT_CONSTRUCTOR is not defined and GNU ld is not
11734 being used. Emits a symbol table alias name with the correct
11735 prefix for collect to find and add to the __CTOR_LIST__.
11736 * chillrt/chillrt0.c: Build on previous hack that gets
11737 _build_exceptions into the __CTOR_LIST__, to make it work
11738 for both the non GNU-ld case and for the SVR4 case.
11740 Tue Dec 22 18:24:55 1992 Bill Cox (bill@cygnus.com)

11756 ch-loop.c: rough draft of location enumeration
11757 ch-lex.l, ch-expr.c, ch-decl.c: minor cleanup
11758 ch-actions.c: finish making pred() and succ() work.
11760 Mon Dec 21 10:04:35 1992 Bill Cox (bill@cygnus.com)
11762 * ch-actions.c: allow pred(char) and succ(char).
11764 Sun Dec 20 16:04:28 1992 Bill Cox (bill@cygnus.com)
11766 * ch-expr.c, ch-actions.c, ch-parse.y, ch-loop.c,
11767 c-expr.c: make DO WITH work.
11769 Sun Dec 20 12:22:53 1992 Bill Cox (bill@cygnus.com)
11771 * ch-loop.c, ch-actions.c, ch-typeck.c: powerset loops
11774 Sat Dec 19 14:20:23 1992 Per Bothner (bothner@cygnus.com)
11776 * c-typeck.c (process_init_constructor): Add warning if
11777 there is a duplicate default initializer element.
11778 * ch-typeck.c (chill_give_type_to_expr): New function,
11779 to handle coercion of an expression to context-given type,
11780 Takes care of untyped tuples, and case expressions.
11781 * ch-decl.c (do_decls), ch-typeck.c (chill_expand_return,
11782 chill_expand_result), ch-parse.y <assignaction>:
11783 Use chill_give_type_to_expr().
11784 * ch-typeck.c (chill_handle_case_label): New parameter list,
11785 to handle the (new) conventions for <case_label>, including
11786 default elements and ranges.
11787 * ch-parse.y <expanded_case_label>, ch-typeck.c
11788 (expand_case_expr): Use new version of chill_handle_case_label.
11789 * ch-decl.c (push_syndecls): Change parameters: Instead of
11790 TREE_LIST representing a compete <synonym definition statement>,
11791 just pass the parts of a single <synonym definition> as 3
11792 different parameters. Also, use chill_give_type_to_expr(),
11793 to handle untyped tuples in the RHS.
11794 * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct
11795 a tree - just call push_syndecls() on each <synonum_definition>
11797 * ch-parse.y (exprlist_get_single): Remove; no longer needed.
11798 * ch-parse.y: Handle <tuple> without mode name diferently from
11799 <tuple> with mode name. The latter is a <primval> that can be
11800 in most contexts, but if the <mode name> is missing, the <tuple>
11801 is only allowed in certain contexts. Use the new non-terminal
11802 <untyped_expr> to indicate those contexts where untyped tuples
11803 (and case expressions) are valid because the expression gets a
11804 type from its context (such as the RHS of an assignment).
11805 Use chill_give_type_to_expr in those contexts.
11807 Sat Dec 19 14:01:26 1992 Bill Cox (bill@cygnus.com)
11809 * ch-actions.c, ch-loop.c, Makefile.in: looping stuff.
11811 Sat Dec 19 10:16:20 1992 Bill Cox (bill@cygnus.com)
11813 * ch-parse.y: clean up warning messages from byacc. bison
11814 still complains thrice.

11818 * ch-actions.c (maybe_chill_comptypes): Delete unused
11820 (chill_comptypes): Add new parameter ERRSTR. All callers
11822 (build_chill_binary_op): Fix indentation to match GNU coding
11825 Fri Dec 18 08:18:13 1992 Bill Cox (bill@rtl.cygnus.com)
11827 * ch-parse.y, ch-expr.c, ch-actions.c, expr.c: major

11837 a default initializer element.
11838 * ch-parse.y: Implement default elements for tuples
11839 (as in '(else):' and '(*):' ).
11841 * ch-parse.y: Previous change to dis-ambiguate case-labels
11842 seems to have allowed getting rid of all of the expr_or_list hair.
11843 * ch-decl.c (do_decls): Undo Tiemann's change to "Handle
11844 initialization of multiple variables by a tuple" - the
11847 Wed Dec 16 11:17:53 1992 Bill Cox (bill@cygnus.com)
11849 * ch-parse.y: complete re-write of DO statement handling.
11850 now operational, except WITH is stubbed out. Improved
11851 syntax error message.
11852 * ch-actions.c: DO support: high_domain_value(), low_domain_value ().
11853 * ch-expr.c: fixes to IN_EXPR handling.
11855 Tue Dec 15 17:15:13 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11857 * ch-grant.c: Add casts to alloca return to avoid compiler warning.
11858 * ch-lex.c: Likewise.
11860 * Makefile.in (ch-lex.c): Delete incorrect free declaration added
11861 by flex to avoid compiler error.
11863 Tue Dec 15 08:41:08 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11865 * ch-decl.c (do_decls): Handle initialization of multiple
11866 variables by a tuple.
11868 * ch-decl.c (do_decls,start_chill_function): Make DECL public
11869 if we're doing a GRANT ALL at top level.
11871 * ch-lang.c (build_range_type): Deal with typecast to CHAR in
11874 * c-typeck.c (digest_init): SET_TYPE is not a scalar type.
11875 BOOLEAN_TYPE and CHAR_TYPE are scalar types.
11877 Mon Dec 14 14:58:32 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11879 * ch-lex.l (get_chill_{linenumber,filename}): New functions.
11880 (convert_number): Use LONG_TYPE_NODE instead of INTEGER_TYPE_NODE.
11882 Mon Dec 14 13:36:44 1992 Bill Cox (bill@cygnus.com)
11884 * expr.c: install and test newer Pascal IN_EXPR code,
11885 but don't activate it - it's very verbose.
11887 Mon Dec 14 00:22:49 1992 Fred Fish (fnf@cygnus.com)
11889 * Makefile.in (LANGUAGES): Add chill.

11905 Sun Dec 13 14:07:32 1992 Bill Cox (bill@cygnus.com)
11907 * ch-actions.c: fix unary operations, modulus ops,
11908 (discovered after extending regression tests).
11910 Sun Dec 13 12:16:32 1992 Bill Cox (bill@cygnus.com)
11912 * resync with Michael and Wilfried

11918 * ch-tree.h: Add declarations for new chill functions that
11919 have been implemented but not (yet) declared.
11921 Sat Dec 12 00:17:23 1992 Per Bothner (bothner@cygnus.com)
11923 * c-typeck.c (process_init_constructor): Warn about duplicate
11924 labels for labelled initializer elements.
11925 * ch-lex.l (various operator tokens, such as "+"): Don't
11926 set yylval.code to a TREE_CODE; this is better done in parser.
11927 * ch-parse.y: Some work with case labels and tuples.
11928 Get literal range as tuple (and case) labels working.
11929 Fix some problems introduced by recent grammar overhaul.

11933 * ch-actions.c, ch-parse.y ch-tree.h ch-expr.c, ch-typeck.c:
11934 got long, real expressions working. We can also call a func-
11935 tion and use its return value.

11939 * ch-parse.y: Major change to remove or at least identify
11940 parser ambiguities. One result: We now allow actions that
11941 start with '(', as required by teh Blue Book. This does break
11942 some things; look for FIXME for things that need work.
11943 * ch-typeck.c (chill_expand_case_expr): We need an extra
11944 level of looping to (in the future) support <case label
11945 specification>s with more than one <case label list>.

11969 on arrays of BOOLs.
11971 Mon Dec 7 08:55:20 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11973 * ch-actions.c (lang_init): Set LINENO to 1 at beginning to
11974 indicate we are done with initialization.
11976 * ch-decl.c (do_decls): Set TREE_PUBLIC if we are doing a
11978 (start_chill_function): Ditto.
11980 * ch-lex.c (convert_bitstring): Set TREE_CONSTANT.
11981 (compiler_directive): Don't confuse compiler directives with
11982 equality comparison operators.
11984 * ch-parse.y: Clear CURRENT_LOCNAMELIST after calling do_decls.

11997 * tree.def: Move CARD_EXPR and SET_LE_EXPR back down with the other
11998 Pascal-required ones, since C++ no longer needs them. When
11999 Chill's public, a comment can be added to the effect that
12000 SET_LE_EXPR is also used by Chill.
12002 Fri Dec 4 12:05:01 1992 Bill Cox (bill@cygnus.com)
12004 * Restore CARD_EXPR and SET_LE_EXPR to tree.def.

12046 * ch-grant.c (decode_constant): New function.
12047 (decode_decl): Call `decode_constant' for CONST_DECLs.
12049 * ch-lex.l (char action): Use ridpointers instead of
12050 lookup_name to get "char"'s declaration.
12052 * ch-parse.y: Call `build_lang_decl' instead of `build_decl'
12053 when we need to build a TYPE_DECL.
12055 Tue Dec 2 09:44:05 1992 Bill Cox (bill@cygnus.com)
12057 * ch-typeck.c: clean up a gcc warning with a forward
12058 declaration of build_string_type.
12060 Tue Dec 1 16:51:05 1992 Bill Cox (bill@cygnus.com)
12062 * ch-actions.c: completely remove those builtin calls
12063 that are duplicated in c-decl.c
12065 Tue Dec 1 16:38:51 1992 Fred Fish (fnf@cygnus.com)
12067 * ch-actions.c (lang_init): Ifdef out initializations for
12068 __builtin_abs and __builtin_fabs, since they are duplicates of
12069 initializations in c-decl.c, and trigger spurious warnings.
12071 Tue Dec 1 16:35:18 1992 Bill Cox (bill@cygnus.com)
12073 * ch-parse.y: make size() work with a typename argument.
12075 Tue Dec 1 16:15:56 1992 Bill Cox (bill@cygnus.com)
12077 * ch-parse.y, ch-lex.l, ch-actions.c: add builtin
12078 functions min, max, card.

12100 Mon Nov 30 17:35:33 1992 Fred Fish (fnf@cygnus.com)
12102 * chillsh: New script frontend (ala g++), installed as "chill".
12103 Can't be called "chill.sh" because make tries to cat it into the
12104 "chill" directory. Can't be called just "chill" cause that's
12105 already there as a directory.
12106 * Makefile.in: Add rules to install chillsh as "chill".
12107 * chill/libchill.c: Temporarily ifdef out stuff that wants
12108 to conflict with i486/SVR4 runtime or wants to pull in librmt.a,
12109 which itself causes linkage to fail.
12111 Mon Nov 30 16:28:19 1992 Bill Cox (bill@cygnus.com)
12113 * ch-lex.l: added keywords for TRUNC, ROUND, FLOAT, LFLOAT
12114 conversion routines.
12115 * ch-parse.y: added %tokens for TRUNC, ROUND, FLOAT, LFLOAT.
12116 Added production for SIZE(expr).
12117 * ch-actions.c: Add semantic routine chill_sizeof ().
12119 Mon Nov 30 16:20:40 1992 Per Bothner (bothner@cygnus.com)
12121 * ch-lex.l, ch-parse.y: Translate token PFEIL into English ARROW.
12122 * ch-parse.y (op6): Remove handling of string repetition operator,
12123 until we can figure out a way to parse it correctly.
12124 * ch-parse.y (optmodename): New non-terminal.
12125 * ch-parse.y (tuple): Merge the two variants using optmodename.
12126 * ch-parse.y (location): Add semantic actions for
12127 dereferencing operator ->.
12129 Mon Nov 30 08:01:29 1992 Bill Cox (bill@cygnus.com)
12131 * ch-actions.c: removed compile warning, better code for abs.
12133 * ch-parse.y: add productions for builtin functions succ, pred,
12134 abs, and size. Add %tokens also. Sort %tokens alphabetically.
12136 * ch-lex.l: add parsing for builtin function names, such as abs,
12137 pred, succ, etc. Put flex -a option into Makefile.in, so we can
12138 clean up the lexer soon.
12140 Tue Nov 24 14:18:48 1992 Per Bothner (bothner@rtl.cygnus.com)
12142 * ch-typeck.c (chill_handle_case_label, chill_handle_case_default):
12143 New functions, for code common to CASE actions and expressions.
12144 * chill.y: Replace some code by calls to chill_handle_case_label
12145 and chill_handle_case_default.
12146 * ch-typeck.c (chill_expand_case_expr): Add semantics.
12148 * tree.c: Change doing_chill_thang from extern to common.
12150 Mon Nov 23 18:34:22 1992 Per Bothner (bothner@rtl.cygnus.com)
12152 * ch-tree.def: New CASE_EXPR type, for case expressions.
12153 * ch-expr.c (chill_expand_expr): Hook for CASE_EXPR.
12154 * ch-typeck.c (chill_expand_case_expr): New function.
12155 Placeholder to implement case expressions.
12156 * ch-typeck.c (chill_expand_result, chill_expand_return):
12157 Handle mode-unspecified tuples and case expressions in
12158 the context of RETURN and RESULT actions.
12159 * chill.y (assignaction): Handle case expressions in the
12160 context of the RHS of an assignment action.
12161 * chill.y (caseaction): Remove spurious duplicate OF in grammar.
12162 * chill.y: Handle labeled structure tuples.
12163 * chill.y: New rules to parse CASE expressions.
12164 * tree.c (build_function_types): Allow Chill functions
12165 to return arrays and functions.
12167 Wed Nov 18 13:50:28 1992 Per Bothner (bothner@rtl.cygnus.com)
12169 * ch-typeck.c (chill_expand_tuple): New function. Expand a
12170 tuple (constructor) given an expected (context) type.
12171 * chill.y: Implement 'LHS := TUPLE' using expand_chill_tuple,
12172 using the mode of the LHS and the expected type of the TUPLE.
12173 * chill.y: Implement initialization.
12174 * chill.y: Fix some syntax bugs (forbidlist must be surrounded
12175 by parentheses), and remove or note ambiguities.
12176 * chill.y: Started converting layout style to be like c-parse.in.
12177 * chill.y: Implement IF expressions.
12178 * chill.y: Added syntax rules for tuples. Labelled and unlabelled
12179 array tuples should now work (in some contexts).
12180 * ch-actions.c: Initialize doing_chill_thang to 1.
12181 * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
12182 initializer, to make pushdecl and finish_decl work.
12183 * c-decl.c (convert_for_assignment): If Chill, don't convert
12184 function and arrays into pointers. (Maybe functions should
12185 still be converted?)
12186 * c-typeck.c (grokdeclarator): Allow functions in Chill
12187 to return arrays and functions.
12189 Mon Nov 16 15:40:47 1992 Per Bothner (bothner@rtl.cygnus.com)

12198 * ch-typeck.c (chill_expand_result); Set TREE_SIDE_EFEFCTS
12199 flags on assignment to result.
12200 * ch-typeck.c (build_chill_array_ref): Subtract lower
12201 bound of domain if non-zero. Preliminary hook for range checking.
12202 * ch-tree.h, chill.l: Combine variables range_check and
12203 range_check_disabled into global variable range_checking.
12204 * ch-tree.h: Better definitions of CH_CLASS_IS_VALUE
12205 CH_CLASS_IS_DERIVED.
