3439 * Makefile.in (C_OBJS): Don't get ../c-iterator.o - not needed.
3441 Thu Sep 15 05:54:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3443 * lex.l (readstring): Add processing of control sequence
3444 in character string literals. The granting mechanism writes
3445 this to grant files.
3447 Tue Sep 13 06:19:42 1994 Wilfried Moser (moser@rtl.cygnus.com)
3449 * expr.c (compare_records): In case of -fpack do always
3450 a memcmp instead of comparing each field of the
3451 structure. If the structure is a variant structure,
3454 Mon Sep 12 13:15:09 1994 Per Bothner (bothner@cygnus.com)
3456 * grant.c (write_spec_module): Add cast, to avoid PCC warning.
3457 * grant.c (header_template): Don't use ANSI-specific string
3458 literal concatenation.
3460 Fri Sep 9 01:53:30 1994 Wilfried Moser (moser@rtl.cygnus.com)
3462 * tasking.c (get_process_wrapper_name): New function.
3463 (add_taskstuff_to_list): Add a new argument, which is
3464 the entrypoint of a process.
3465 (build_process_header): Change PROCESS arguments to be
3466 like arguments of a function. There will be a wrapper
3467 which is the real entry point for a PROCESS. This wrapper
3468 is automatically build after a PROCESS definition and gets
3469 as argument a pointer to a structure looking like the
3470 arguments of the PROCESS. This wrapper will call the
3471 PROCESS (see build_process_wrapper).
3472 (build_process_wrapper): New function (see above).
3473 (build_start_process): Change processing of arguments.
3474 (tasking_setup): Add processing of a different entry point
3475 in case of PROCESSes.
3477 * parse.c (parse_process_definition): Add call to
3478 build_process_wrapper.
3479 * parse.c (end_function): Remove the poplevel() call.
3480 build_process_header no longer makes the corresponding
3483 * grant.c (print_proc_tail): Remove special processing
3484 of PROCESSes, they look now like normal functions.
3486 * decl.c (init_decl_processing): Add declaration of memcmp
3489 * ch-tree.h: Add new prototype for build_process_wrapper,
3490 change prototypes for add_taskstuff_to_list and
3491 build_process_header.
3493 * grant.c (write_spec_module): Write GNUCHILL and gcc
3494 version into grant file.
3496 * Make-lang.in (CHILL_FLAGS_TO_PASS): Add passing of CC and
3497 GNUCHILL_VERSION to ch/Makefile.
3498 * Make-lang.in (CHILL.mostlyclean): Add ch/ch-version.c.
3500 * Makefile.in (CHILL_OBJS): Add ch-version.o. ch-version.c
3501 will get generated every time a new Makefile will get
3503 * Makefile.in (GNUCHILL_VERSION): Remove it, its defined in
3506 * chill.in: In case of -fgrant-only pass "-S -o /dev/null"
3507 to the compiler to avoid generation of an object file.
3509 Thu Sep 8 12:07:28 1994 Per Bothner (bothner@kalessin.cygnus.com)
3511 * convert.c (display_int_cst), ch-tree.h: New function.
3512 * convert.c (digest_array_tuple): Use digest_int_cst to
3513 provide better error messages. Return error_mark_node on error.
3514 * grant.c (decode_const): Simplify by using digest_int_cst.
3515 * grant.c (format_character, find_assoc): Removed.
3517 * decl.c (do_decl): Add missing TREE_CHAIN.
3519 * decl.c (finish_incomplete_decl): Removed.
3520 (init_decl_processing): Don't set incomplete_decl_finalize_hook.
3521 (finish_decl): Remove old C-specific code to deduce size of
3522 array from initialization.
3523 (complete_array_type): Just make it abort.
3525 * except.c (finish_handler_array): Avoid calling C-specific kludge
3526 complete_array_type.
3528 * convert.c (digest_constructor): Rename, and re-write to:
3529 (digest_array_tuple, convert): No longer use the code in
3530 ../c-typeck.c; use a Chill-only implementation (sigh).
3532 * typeck.c (chill_expand_tuple): Remove unneeded call to
3533 complete_array_type.
3535 * expr.c (fold_set_expr), grant.c (decode_constant),
3536 typeck.c (expand_constant_to_buffer): Update name of called
3537 function unpack_set_constructor to get_set_constructor_bits.
3538 * expr.c (powersetlen ): Remove redundant call to convert.
3540 * ch-tree.h (unpack_set_constructor): Removed obsolete declaration.
3542 * inout.c (build_chill_writetext): Handle 64-bit integer literals
3543 by trying to convert them to a smaller type.
3545 * lex.l (convert_number): Always use long long type (possibly
3546 unsigned) to avoid problems with constant folding truncation.
3548 Mon Sep 5 08:08:22 1994 Wilfried Moser (moser@rtl.cygnus.com)
3550 * ch-tree.h (enum chill_built_in_function): Add BUILT_IN_QUEUE_LENGTH.
3551 Add new prototype (see tasking.c).
3553 * expr.c (build_generalized_call): Add processing of
3554 BUILT_IN_QUEUE_LENGTH.
3556 * tasking.c (build_queue_length): New function.
3558 * tasking.c (tasking_init): Add new external function definition.
3560 Thu Sep 1 15:38:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3562 * lex.l (default_lex): New function. Progress towards
3563 getting rid of [f]lex.
3565 * lex.l (convert_number): Use mul_double and add_double.
3566 Set result type to a reasonable type in which the literal
3567 will fit. Give error message if literal is too big.
3569 * lex.l (equal_number): Switch (temporarily) to permanent obstack.
3571 * typeck.c (build_chill_slice_with_range): Check for empty
3572 slice *after* we have checked for upper/lower limit in range.
3574 * grant.c (decode_mode): Remove unused code. (BOOL and
3575 CHAR ranges are represented as INTEGER_TYPEs.)
3577 * tasking.c (build_process_header): Add missing call to
3578 expand_start_bindings.
3579 * parse.c (end_function): Add missing expand_end_bindings.
3581 Wed Aug 31 17:25:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3583 * decl.c (init_decl_processing): Set set_alignment.
3585 Tue Aug 30 16:40:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
3587 * actions.c (print_missing_cases, check_missing_cases,
3588 BITARRAY_TEST, BITARRAY_SET): New functions and macros,
3589 to check for completeness of case actions and expressions.
3590 * decl.c (c_decode_option, init_decl_processing):
3591 Don't set warn_switch.
3592 * expr.c (chill_expand_case_expr): Call check_missing_cases
3593 instead of check_for_full_enumeration_handling.
3594 * parse.c (parse_case_actions): Call check_missing_cases.
3596 * expr.c (build_chill_binary_op): Remove some dead code.
3597 * expr.c (chill_truthvalue_conversion): Call build_chill_binary_op
3598 instead of build_binary_op.
3599 * ch-tree.h (binary_op_error, build_binary_op): Unused. Removed.
3601 * parse.c (end_function): Use kept_level_p in parameter to
3602 poplevel. This reverts a June 13 change.
3604 Fri Aug 26 11:50:19 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3606 * configure: Ignore --without, as ../configure does.
3608 Wed Aug 24 01:17:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3610 * lex.l: Change rule for decimal numbers to allow identifiers
3611 to start with an underscore (_).
3613 Fri Aug 19 16:38:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
3615 * tasking.c (build_receive_signal_case_label): Remove backwards
3616 chill_convert_for_assignment (which converted whatever garbage
3617 was in the *target* to the type of the signal argument!).
3619 Fri Aug 19 07:10:43 1994 Wilfried Moser (moser@rtl.cygnus.com)
3621 * inout.c (build_chill_io_list_type, build_enum_tables),
3622 tasking.c (build_tasking_struct): Temporarily reset
3623 maximum_field_alignment to 0, so that the compiler-built
3624 data structures needed by the RTS can be independent of -fpack.
3626 Thu Aug 18 13:39:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3628 * typeck.c (build_init_struct): Temporarily reset
3629 maximum_field_alignment to 0, so that the compiler-built
3630 data structures needed by the RTS can be independent of -fpack.
3632 Wed Aug 17 23:48:33 1994 Wilfried Moser (moser@rtl.cygnus.com)
3634 * parse.c (parse_primval, expect, parse_on_exception_list):
3635 Print error message only in pass 2.
3637 Wed Aug 17 13:47:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3639 * decl.c (switch_to_pass_2): Revert June 13 change,
3640 (Don't exit after pass 1 if an error was found.)
3642 * ch-tree.def (SLICE_EXPR): New tree-code.
3643 * typeck.c (build_chill_slice): For building a slice of a
3644 bit-string, just generate a SLICE_EXPR.
3645 * decl.c (init_decl_processing): Declare __pscpy.
3646 * actions.c (chill_expand_assignment): Handle a SLICE_EXPR
3647 on the LHS of assignment, by calling __pscpy.
3648 * expr.c (chill_expand_expr): Handle SLICE_EXPR (as a RHS
3649 value) by using __psslice to copy slice to a temp.
3651 Wed Aug 17 05:52:44 1994 Wilfried Moser (moser@rtl.cygnus.com)
3653 * Make-lang.in: Change version of GNUCHILL compiler to 1.4.1.
3654 * expr.c (build_chill_length): Enable LENGTH built-in to process
3655 Buffers and Events too (Z.200/1992).
3656 * lex.l (yywrap): Always set yyin to finput and/or grt_in. On
3657 a linux system the previous version was not able to run.
3658 * tasking.c: Correct processing of infinite buffer- and event-length
3659 to avoid RANGEFAIL warning.
3661 Thu Aug 11 11:46:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3663 * parse.c (parse_if_expression_body): Don't call the C-specific
3664 build_conditional_expr. Just do build_nt (COND_EXPR, ...).
3665 * convert.c (convert): Convert a COND_EXPR by converting
3668 * convert.c (convert): Don't call convert before
3669 convert_to_reference. It's apt to do weird and unneedful things.
3670 * convert.c (convert): If the expression is varying, just call
3671 varying_to_slice, which simplifies quite a bit.
3673 * ch-tree.h (varying_to_slice): Add prototype.
3674 * typeck.c (varying_to_slice): Remove prototype.
3676 * satisfy.c (satisfy): Move case PAREN_EXPR from type 'e'
3679 * except.c (emit_setup_handler): Temporarily reset the
3680 maximum_field_alignment to zero so the compiler's exception
3681 data structures can be compatible with the run-time system,
3682 even when we're compiling with -fpack.
3684 * expr.c (compare_records): Call saved_if_needed on operands.
3686 * expr.c (build_set_expr case NE_EXPR): Don't use __nepowerset
3687 which has been reimplemented to just call __eqpowerset and
3688 invert the result. Inline this new implementation by
3689 handling as EQ_EXPR, and inverting the result.
3690 * decl.c (init_decl_processing): Don't define unused __eqpowerset.
3692 * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
3693 type boolean_type_node, not void_type_node. (Fixing this
3694 avoids a crash in the back-end.)
3696 * grant.c (decode_constant): In a CALL_EXPR, if the argument
3697 list is not a TREE_LIST (as in string repetiation), don't
3700 Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3702 * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
3703 CONST_DECL is from a SET definition. (This is safer than
3704 checking that the type is ENUMERAL_TYPE, because synonym
3705 definitions may have a NULL TREE_TYPE.)
3706 Also, if we have duplicate enums whose types are identical,
3708 * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
3709 an extra 'quiet' parameter, which is true if we're called from
3710 bind_sub_modules. (In that case an error message about duplicated
3711 decls would be repeated later, so suppress it.)
3713 * parse.c (stmt_count): Removed, not used.
3714 (INIT_ACTION): Call emit_line_note only if !ignoring.
3715 (parse_begin_end_block): Do INIT_ACTION even if ignoring.
3717 Fri Aug 5 12:39:11 1994 Per Bothner (bothner@kalessin.cygnus.com)
3719 * parse.c (parse_untyped_expr): Add missing semi-colon.
3721 Thu Aug 4 17:40:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
3723 * parse.c (parse_untyped_expr): Fix various problem for the
3724 case that we see a '(': Add missing 'case' keyword.
3725 Only recurse if '(' is followed by 'if', 'case' or '[',
3726 and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
3728 * parse.c (parse_send_action): Remove extra nreverse.
3730 Thu Jul 28 04:00:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3732 * expr.c (build_allocate_global_memory_call, build_allocate_memory_call):
3735 Tue Jul 26 22:48:15 1994 Michael Tiemann (tiemann@blues.cygnus.com)
3737 * parse.c (parse_untyped_expr): Added missing "case" before LPRN.
3738 Added a missing call to `require' as well.
3740 Tue Jul 19 10:30:12 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3742 * lex.l (yywrap): Define as yywrap_chill to avoid conflicts with
3743 the extern declaration in the flex skeleton.
3745 Mon Jul 18 23:06:04 1994 Per Bothner (bothner@kalessin.cygnus.com)
3747 * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
3748 Check the type of the instance expr using CH_COMPATIBLE,
3749 and not just == instance_type_node. (This allows
3750 the expression to have mode READ INSTANCE).
3751 * tasking.c (build_instance_type): Give instance_type_node
3752 a non-null novelty (i.e. different from a struct).
3753 * tasking.c (build_receive_case_start, build_delay_case_start):
3754 Check that for a location using CH_LOCATION_P.
3756 Mon Jul 18 13:22:23 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
3758 * expr.c (finish_chill_unary_op): Use TREE_SET_CODE not TREE_CODE
3759 to modify a tree code.
3761 Mon Jul 18 11:24:57 1994 Bill Cox (bill@rtl.cygnus.com)
3763 * convert.c (digest_structure_tuple): Fix thinko in TREE_CODE
3766 Mon Jul 18 05:40:15 1994 Doug Evans (dje@canuck.cygnus.com)
3768 * decl.c (warn_bad_function_cast): Define so cc1chill will link.
3770 Thu Jul 14 18:37:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3772 * parse.c (parse_send_action): Do tree_cons *before* checking
3775 Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3777 * convert.c (digest_structure_tuple): Don't use convert to
3778 coerce initial value, use chill_convert_for_assignment instead.
3779 (Thus we also get range_checking.)
3781 * expr.c (build_chill_card): Use force_addr_of instead of
3782 build_chill_addr_expr.
3784 * loop.c (build_temporary_variable): Stylistic tweak.
3785 * loop.c (maybe_make_for_temp): Initialize temp using
3786 explicitly, not using assignment. Avoids a problem if
3787 the expression is read-only.
3788 * typeck.c (smash_dummy_type): Always used the saved TYPE_NAME
3789 and CH_NOVELTY_FLAG.
3791 Wed Jul 6 20:12:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3793 * expr.c, ch-tree.h (finish_chill_unary_op): New function,
3794 based on code ripped out of build_chill_unary_op.
3795 (build_chill_unary_op): Call finish_chill_unary_op unless pass==1.
3796 * satisfy.c (satisfy): Call finish_chill_unary_op when needed.
3798 Mon Jun 27 11:29:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3800 * tree.c (save_if_needed), ch-tree.h: New function.
3801 * typeck.c (build_chill_slice_with_range,
3802 build_chill_slice_with_length): Call save_if_neeed on array arg.
3803 * expr.c (varying_to_slice): Re-write to use save_if_needed.
3805 * typeck.c (extract_constant_from_buffer): Handle BOOLEAN_TYPE.
3807 Mon Jun 27 01:11:10 1994 Wilfried Moser (moser@rtl.cygnus.com)
3809 * inout.c (build_chill_io_list_type): Change layout of __tmp_WIO_list
3810 that it is always the same, regardless if compiled with -fpack
3813 Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3815 * lex.l (yywrap): Kludge to work around mis-synchronization
3816 between lexer (which read ahead) and parser: Don't emit
3817 (left-over) uze_seizefile directives at the end of file.
3819 * typeck.c (build_chill_array_ref): Allow the derived
3820 array indexing syntax for arrays of bit strings.
3821 Add a comment explaining why.
3823 * typeck.c, ch-tree.h (string_assignment_condition): Change
3824 the interface. Return a boolean expression (which can be
3825 used in a conditional at run-time); never expand anything.
3827 * actions.c (chill_convert_for_assignment): Check
3828 string_assignment_condition here, rather than in callers.
3829 * actions.c (chill_expand_assignment): Don't need to check
3830 string_assignment_condition here.
3831 * expr.c (build_chill_function_call): Likewise.
3832 * satisfy.c (safe_satisfy_decl): Update accordingly.
3833 * decl.c (do_decl): Simplify testing and conversion by
3834 deferring everything to chill_convert_for_assignment.
3836 * parse.c: Combine the two variables 'ignore_exprs' and
3837 'ignore_actions' into one variable called 'ignoring'.
3838 * ch-tree.h: Add 'extern int ignoring'.
3839 * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
3840 Rename ignore_actions and ignore_exprs to ignoring.
3841 Remove unneeded extern declarations.
3842 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3843 build_chill_arrow_expr, build_generalized_call, build_delay_action,
3844 build_buffer_type, build_event_type): I changed my mind. It is
3845 cleaner to check for 'ignoring' in the parser, rather than here.
3846 * parse.c (parse_action, parse_primval, parse_opt_mode):
3847 Therefore we must check for ignoring here.
3848 * parse.c (parse_loc_declaration): Set ignoring in pass 2
3849 when parsing the mode.
3851 * tasking.c (generate_tasking_code_variable): Do arithmetic
3852 on signal_code etc using unsigned rather than signed shorts.
3854 * grant.c (static char* current_grant_modename): Removed.
3855 * grant.c (decode_decl case CONST_DECL): Remove error message.
3857 * Make-lang.in (CHILL_SRCS): Add $(srcdir)/ch/parse.c.
3858 * Makefile.in: Fix dependencies for parse.o.
3859 Remove some duplicate dependencies for $(TREE_H).
3861 Mon Jun 13 14:25:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3863 * typeck.c (build_chill_cast): Allow a value cast between
3864 non-discrete object of the same size, but with a pedwarn.
3865 * typeck.c (bit_string_assignment_condition,
3866 char_string_assignment_condition): Merge near-duplicate functions
3867 and place the code in string_assignment_condition.
3869 * decl.c (parm_flag, declare_parm_level, in_param_level_p):
3871 * decl.c (start_chill_function, finish_chill_function): Make
3872 parameter level have same nesting level as body, as required by Z200.
3873 * decl.c (switch_to_pass_2): Always exit if an error has been found.
3874 * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
3875 generated from GRANT ALL.
3876 * decl.c (lookup_name_for_seizing): Don't seize from
3877 the nesting level of builtins (predefined objects).
3878 * decl.c (lookup_name_for_seizing): Make more robust on error.
3880 * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
3881 be 'RESULT' (or 'result'). This makes it more accessible from gdb.
3882 Also, use do_decl to declare it, so that debugging symbols are
3883 generated. And, re-arrange so that actions that need to
3884 be done both passes (such as push_levels) use the same code.
3886 * parse.c (get_type_of): If ignore_exprs, don't lookup name.
3887 * parse.c (end_function): Fix poplevel params.
3888 * parse.c (expect): Don't read forwards on an error.
3889 * parse.c (parse_field): Don't define two tag_list locals!
3890 * parse.c (parse_pass_1_2): Better error message.
3892 * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
3893 parse_opt_mode, rather than vice versa. If parse_opt_mode
3894 returns NULL_EXPR, then parse_mode gives an error.
3895 Change parse_opt_mode (and any functions it calls) to only
3896 return NULL_TREE if there is no mode (even on ignore_exprs).
3897 (parse_set_mode, parse_structure_mode, parse_procedure_mode):
3898 Never return NULL_EXPR.
3899 * tasking.c (build_buffer_type, build_event_type): Return
3900 void_type_node instead of NULL_EXPR if ignore_exprs is true.
3902 * parse.c (parse_synonym_definition): Call parse_untyped_expr
3903 only if we have a mode.
3904 * parse.c (parse_send_action): Parse list of untyped_expr's,
3905 rather than a list of (typed) expressions.
3906 * parse.c (parse_primval): Emit error if '[' seen without
3907 preceding mode name. (If this is to be allowed, call
3908 parse_untyped_expr instead.)
3910 * parse.c (parse_array_index): Renamed to ...
3911 (parse_index_mode): ... to match Z200 terminology.
3912 Re-write to resolve some of the nastier ambiguities,
3913 and allow things like ' CHAR(10) : CHAR(20) '.
3915 * parse.c (parse_tuple_element): Change interface to return
3916 reversed list, so don't call nreverse.
3917 * parse.c (parse_tuple): No longer nreverse element list here.
3918 * parse.c (parse_opt_element_list): Do nreverse here instead.
3919 * parse.c (parse_case_label_list): Call nreverse at end.
3921 Fri Jun 10 15:36:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
3923 * typeck.c (chill_similar): Remove bogus "else".
3925 Wed Jun 8 00:01:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
3927 * ch-tree.h (TYPE_ARRAY_MAX_SIZE): New macro (and comment)
3928 to make it clearer that we are using TYPE_MAX_VALUE in a special way.
3929 * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
3930 * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
3931 * convert.c (convert): When converting a fixed string/array
3932 to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
3933 of (the type of) the padding.
3934 * convert.c (convert): If the concatenation is non-constant, use
3935 the low-level 'build' to set the type of the result (which is usually
3936 a fixed-size array) rather than depend on build_chill_binary_op
3937 to figure it out (it's unable to simplify the size to a constant).
3939 Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
3941 * lang.c (lang_decode_option): Let -fspecial_UC imply
3942 -fno-ignore-case without requiring it explicitly.
3943 * lang.c (lang_decode_option): Support (experimentally)
3944 the -fpack and -fno-pack flags.
3946 Thu Jun 2 20:49:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3948 * configure: Add support for --program-prefix and --program-suffix.
3950 Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3952 * convert.c (digest_constructor): Check that initial value
3953 is compatible with element mode before calling convert.
3954 * typeck.c (chill_compatible): A string mode is not compatible
3955 with an untyped constructor.
3956 * decl.c (do_decl): Clean up error messages. Use error_with_decl.
3958 * ch-tree.h: Fix inconsistencies: bool_true_node ->
3959 boolean_true_node, and bool_false_node -> boolean_false_node.
3960 * typeck.c (valid_array_index_): Minor simplification.
3962 Tue May 31 04:33:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3964 * inout.c (build_chill_writetext): Add correct processing
3965 of POWERSET RANGE (setmode).
3967 * lex.l (same_file): Add searching for file(s) in
3970 Fri May 27 14:22:42 1994 Per Bothner (bothner@kalessin.cygnus.com)
3972 * Make-lang.c (CHILL.mostlyclean, CHILL.distdir): Don't list
3973 yacc/bison output files, since the grammer is no longer in yacc.
3974 * config-lang.in (diff_excludes): Likewise.
3976 Thu May 26 16:38:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3978 * gperf, hash.h, lex.l, parse.h: Rename PROCESS_TYPE token
3979 (in some files spelled PROCESS_TYPE_ to avoid clashes
3980 with the PROCESS_TYPE tree_code) to PROCESS_TYPE_TOKEN.
3982 Thu May 26 02:18:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3984 * timing.c (build_cycle_start): Change call to __define_timeout.
3985 * decl.c (init_decl_processing): Change definitions of
3986 __define_timeout and __wait_timeout.
3988 Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
3990 Replace yacc-based parser with a recursive-decent parser.
3991 (This may seem backwards, but Chill [like C++] is not a
3992 language that is remotely LALR(1). Using a R-D parser
3993 allows us to use look-ahead and to back-up to resolve the
3994 difficult ambiguities.)
3996 * parse.c, parse.h: New files, containing new r-d parser.
3997 * Makefile.in: Update accordingly.
3998 * actions.c (chill_convert_for_assignment): Don't return
3999 NULL_EXPR if ignore_exprs is true. It simplifies the parser
4000 if we consistently reserve NULL_EXPR for a missing expression.
4001 * expr.c (build_chill_function_call): Likewise.
4003 * lex.l: Tweaks for new parser.
4004 * lex.l (prepare_paren_colon, paren_paren_colon_level,
4005 paren_level): Ugly hack no longer needed.
4007 * expr.c (build_chill_function_call): Cleanup.
4008 Call chill_convert_for_assignment to convert IN/INOUT
4009 paramaters on both input and output. For LOC parameters,
4010 give error if actual is a non-referable location.
4011 * actions.c (convert_for_assignment): Add new parameter (a
4012 "place" string used in error messages).
4013 * actions.c (adjust_parm_or_field): Removed.
4014 * actions.c (chill_expand_assignment): Take just a single LHS,
4015 and move support for multiple assignments to ...
4016 (expand_assignment_action): ... here. Some cleaning up.
4017 * timing.c (build_cycle_start): Adjust accordingly.
4018 * actions.c (expand_assignment_to_varying_array): Likewise.
4019 * tasking.c (many places): Ditto.
4020 * ch-tree.h: Fix declarations appropriately.
4022 * parse.c (parse_defining_occurrence_list): Return a single
4023 IDENTIFIER_NODE (instead of a singleton list) in the common
4024 case. Minor complication to save a minor amount of space.
4025 * decl.c (do_based_decls): Move guts of code into ...
4026 (do_based_decl): ... this new function.
4027 * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
4028 * decl.c (push_syndecl): Replace by ...
4029 (push_syndecl): ... (which only supports a single name).
4030 (push_modedef): Only handle a single name.
4031 * tasking.c (build_process_header, build_signal_struct_type):
4034 * expr.c (build_generalized_call): Handle string repetition.
4035 * expr.c (build_chill_repetition_op): Change interface.
4036 * grant.c (decode_constant): Allow parameter list to be
4037 a non-TREE_LIST. (Used for string repetition.)
4039 Wed May 25 11:28:48 1994 Per Bothner (bothner@kalessin.cygnus.com)
4041 * lex.l (make_identifier): Replaced by ...
4042 (read_identifier, handle_name): ... new functions.
4043 * lex.l: Parse an identifiers using read_identifier using
4044 read_identifier and handle_name, rather than having [f]lex
4045 do it. (One reason is that lex uses a fixed-size buffer.)
4047 * lex.l (read_directive, skip_directive): New functions.
4048 Use them to parse compiler-directives, instead of rather
4049 ugly and useless use of lexer start conditions.
4051 Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4053 * decl.c (unnamed_module_number): Renamed to ...
4054 (module_number): .. and make non-static.
4055 (push_module): Always increment module_number.
4056 * lex.l (yywrap): Print warning if no modules seen.
4058 * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
4059 decl to current_seizefile_name (which is unreliable).
4060 * grant.c (chill_grant): Set it here instead.
4062 * expr.c (fold_set_expr): Use int_size_in_bytes instead of
4063 TYPE_PRECISION (which is not defined for a SET_TYPE).
4065 Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
4067 Cleanup to remove need for variables in common storage.
4068 * decl.c: Remove unused use of current_obstack.
4069 * actions.c (maybe_chill_check_decl): Remove unused function.
4070 * actions.h, lang.c: Remove uses of doing_chill_thang.
4071 * ch-tree.h (void_list_node): Make extern (rather than common).
4072 * decl.c (void_list_node): Add definition.
4074 Thu May 19 06:54:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
4076 * configure (build): Build canon_host and canon_target
4077 to pass it to all subsequently generated Makefiles (needed
4078 for testsuite/execute in case of cross build).
4080 Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4082 * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
4083 the input type, which loses with the no-longer-new 2-pass
4084 implementation, since the input "type" could be an IDENTIFIER_NODE.
4085 * grant.c (raw_decode_mode): Rename to decode_mode.
4087 Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
4089 * typeck.c (chill_location): Neither a STRING_CST nor a
4090 CONSTRUCTOR is a location.
4091 * typeck.c (chill_root_mode): Convert a function to a
4092 pointer-to-function.
4093 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
4094 build_chill_arrow_expr): If ignore_exprs, return operand
4095 rather than NULL_EXPR. This makes it easier for the parser to
4096 distinguish missing expressions.
4097 * expr.c (build_max_min): Convert the lower bound of a
4098 set to a long before calling run-time routine.
4099 * expr.c (build_chill_pred_or_succ): Use discrete_type_p
4100 to check the argument type.
4101 * expr.c (build_chill_arrow_expr): If argument is not a location,
4102 do a predwarn if it is a STRING_CST or has function type.
4104 Tue May 17 06:05:13 1994 Wilfried Moser (moser@rtl.cygnus.com)
4106 * configure (build): Remove building of canon_host and canon_target.
4107 It doesn't work in any case.
4109 Mon May 16 02:10:35 1994 Wilfried Moser (moser@rtl.cygnus.com)
4111 * configure (build): Build canon_host and canon_target
4112 to pass it to all subsequently generated Makefiles (needed
4113 for testsuite/execute in case of cross build).
4114 * Make-lang.in (chill-runtime): Change chill to CHILL in the case
4115 statement to build chill-runtime automatically.
4117 Mon May 9 15:30:08 1994 Doug Evans (dje@canuck.cygnus.com)
4119 * Makefile.in (FLAGS_TO_PASS): Define.
4121 (../cc1chill): Depend on $(OBJDEPS) $(C_OBJS).
4122 * Make-lang.in (cc1chill): Delete dependency on $(OBJS) $(BC_OBJS).
4123 (CHILL.mostlyclean): Use `mostlyclean' as recursive target.
4125 Sun May 8 13:05:00 1994 Per Bothner (bothner@cygnus.com)
4127 * Make-lang.in (cc1chill): Should not depend on libgcc.a.
4129 Thu May 5 18:58:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
4131 * decl.c (copy_lang_decl): New (dummy) function.
4133 Mon May 2 14:33:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
4135 * parse.y (sendaction): Fix thinko (in sense of condition).
4136 * tasking.c (build_receive_case_label): Another thinko.
4138 * parse.y (optsigdest): Force ignore_exprs to 0 while parsing
4141 * decl.c (build_chill_function_type): Don't call layout_type
4142 (since that may prevent parameter or result types being
4143 properly satisfied).
4144 * satisfy.c (satisfy): Layout FUNCTION_TYPEs.
4145 * parse.y (procmode): Call build_chill_pointer_type, rather
4146 than build_pointer_type (which incorrectly sets TYPE_SIZE).
4148 * parse.y (get_type_of): Handle TYPE_DECL (again).
4149 * parse.y (optresultspec): Call build_chill_reference_type, rather
4150 than build_reference_type (which incorrectly sets TYPE_SIZE).
4151 * parse.y (range_or_mode): Rename to plain range, since it
4152 no longer matches modename.
4153 * actions.c (chill_handle_case_label_range): New function, with
4154 functionality moved out of chill_handle_case_label.
4155 * actions.c (chill_handle_case_label): Handle here the case that
4156 the label_value is a TYPE_DECL (modename). Also clean up some.
4157 * typeck.c (build_chill_slice_with_length): Convert max_index
4158 to the type of min_value. (Old code broke on varying strings.)
4160 Sun May 1 13:53:36 1994 Doug Evans (dje@canuck.cygnus.com)
4162 * Makefile.in (BC_OBJS): Delete all references
4163 (OBJS): Cat ../stamp-objlist to get language independent files.
4164 (../cc1chill): Delete dependency on $(OBJS).
4165 * Make-lang.in (cc1chill): Depend on stamp-objlist.
4167 Sat Apr 30 14:50:15 1994 Per Bothner (bothner@kalessin.cygnus.com)
4169 * lex.h, lex.c: Remove lastiddecl.
4170 * lex.l (name_type_signal): Simplify. We no longer check for
4171 TYPENAME or SIGNALNAME (which was unreliable with two passes).
4172 Also rename to make_identifier.
4173 * parse.y: Cleaned up grammar to not need SIGNALNAME or TYPENAME.
4174 * Makefile.in (stamp-parse); One conflict fewer!
4175 * parse.y (rccase_label_flag): Moved to tasking.c.
4176 * parse.y (rccase_label): Move most of the logic to
4177 build_receive_case_label in tasking.c.
4178 * parse.y (sendaction): Re-write to not depend on SIGNALNAME.
4180 * parse.y (name): Do name lookup here (and not in location).
4181 * parse.y: Replace most uses of NAME by higher-level non-terminals:
4182 simple_name_string, name_string, defining_occurrence, or name.
4184 * tasking.c (build_receive_signal_case_label,
4185 build_receive_buffer_case_label): New functions, split out from
4186 build_receive_case_label.
4187 * tasking.c (build_receive_case_label): Change parameters
4188 and return type. Moved stuff here (from the parser).
4189 * tasking.c (struct rc_state_type): Removed had_errors.
4190 Return error_mark_node instead.
4191 * tasking.c (build_rccase_set_error), ch-tree.h: Removed.
4193 * expr.c (build_generalized_call): If func is a signal type,
4194 call build_signal_descriptor.
4196 * parse.y (arrayindex): Renamed to index_mode, to match Z.200.
4197 * parse.y (ioindexmode): Removed; use index_mode instead.
4198 * expr.c (build_generalized_call): If args is a RANGE_EXPR,
4199 we have either a slice or a range mode, depending on func.
4200 * parse.y (index_mode): If we got an 'expr', only allow a name,
4202 * parse.y (call): A slice with both end points can be a range
4203 mode, so defer handling to build_generalized_call (or index_mode).
4205 * typeck.c (build_chill_slice_with_length): Fix type-checking.
4206 * typeck.c (chill_novelty): Undo (part of) change of April 28:
4207 The novelty of a range mode is the novlety of the parent.
4208 * typeck.c (chill_root_mode): Don't return integer_type_node
4209 if argument has non-nil novelty.
4211 * decl.c (global_bindings_p): Return -1 as true, for the sake
4212 of variable_size (in ../stor-layout.c).
4214 Fri Apr 29 13:42:43 1994 Per Bothner (bothner@kalessin.cygnus.com)
4216 * parse.y: Remove TYPENAME and modename. These are now plain
4217 NAMEs. Modify parsing actions appropriately.
4218 * expr.c (build_generalized_call): Handle the case that
4219 TREE_CODE (func) == TYPE_DECL (as in a cast).
4220 * lex.l (name_type_signal): Never return TYPENAME.
4221 * parse.y (get_type_of): If pass 1, just return the argument.
4223 * decl.c (do_decl): If an initializer has the wrong type,
4224 replace it by NULL_TREE, to avoid subsequent errors.
4226 Thu Apr 28 15:21:56 1994 Wilfried Moser (moser@rtl.cygnus.com)

4259 call one of the above mentioned functions.
4260 * tasking.c (build_delay_case_start, build_delay_case_label,
4261 build_delay_case_end): Rewritten due to new implementation of events.
4262 * tasking.c (build_delay_action): Rewritten due to new implementation
4264 * tasking.c (expand_send_buffer), ch-tree.h: New function.
4265 * timing.c (build_at_action, build_cycle_start, build_cycle_end),

4270 * typeck.c (smash_dummy_type): Handle the special case of a
4271 NEWMODE of a range mode, as required by Z200, by creating a
4272 new parent mode with the new novelty (and casting the min
4273 and max of the range to teh new parent mode).
4274 * typeck.c (chill_novelty, chill_root_mode): Remove special
4275 kludges for of NEWMODE ranges.
4276 * expr.c (build_chill_lower_or_upper): New function, combining
4277 the "guts" of build_chill_lower and build_chill_upper.
4278 * expr.c (build_chill_lower_or_upper): Simplify; no longer
4279 need to kludge the novelties.
4281 * typeck.c (valid_array_index_p): A string index expression
4282 need not be Compatible with the index type; only similar.
4284 * decl.c (layout_chill_variants): If error seen, skip stuff
4285 (rather than aborting or crashing).
4286 * decl (push_modedef): If newdecl's type is an error mark,
4287 continue rather than aborting.
4289 Thu Apr 28 02:07:42 1994 Doug Evans (dje@cygnus.com)
4291 * Make-lang.in: Update of directory reorg from fsf.
4292 * config-lang.in: Ditto.
4294 Mon Apr 25 13:09:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
4296 * typeck.c (chill_similar): Check RECORD_TYPEs properly,
4297 * convert.c (convert): If all else fails, just call convert1.
4298 Thus we can now convert RECORD_TYPEs (assuming they are similar).
4300 * parse.y, lex.l: Remove BUFFERNAME (use location/expr instead).
4301 * parse.y: Re-do BUFFER handling (similar to previous EVENT change).
4302 * grant.c (raw_decode_mode): Re-do BUFFER mode handling.
4303 * ch-tree (lang_type_record): Removed max_queue_size field.
4304 * tasking.c (build_buffer_type): Re-write.

4307 * tasking.c ch-tree.h (expand_send_buffer): Now has 3 parameters.
4308 * parse.y (modename): No longer match SIGNALNAME. Instead, add it
4309 to name and simple_name_string. This removes a reduce/reduce conflict.
4310 * Makefile.in (stamp-parse): Expect fewer conlicts.
4312 * lex.l (yywrap): Move check for circularly seizeing current
4313 grant-file from here ...
4314 * lex.l (handle_use_seizefile_directive): ... to here.
4315 This is to avoid calling stat on a not-yet written grantfile,
4316 now that we're using same_file (which calls stat).
4317 * grant.c (set_use_this_gf): Removed.
4318 * grant.c (set_default_grant_file): Set grant_file_name here,
4319 because we need it earlier (due to above lexer change).
4321 * typeck.c (layout_chill_struct_type): Remove useless code to
4322 remove zero-width bitfield (which messes up CONST_DECLs).
4324 Sat Apr 23 13:16:39 1994 Bill Cox (bill@rtl.cygnus.com)
4326 * Makefile.in (check): Assure that 'ld' is available before checking.
4328 Thu Apr 21 13:23:54 1994 Per Bothner (bothner@kalessin.cygnus.com)
4330 * grant.c (print_an_int): Removed.
4331 (raw_decode_mode): Generalized to use decode_constant
4332 instead of print_an_int.

4343 Re-implement EVENT modes to support general EVENT objects
4344 (and not just EVENT names), according to Z200. (Not finished!)

4415 * actions.c (chill_expand_assignment): Check for compatibility
4416 _after_ "expanding out" a binary operation. This fixes
4417 the case "STRING //:= CHAR".
4419 * lex.l (equal_number): Convert symbol to integer_type_node, to
4420 force the value to be INT-derived (and avoid novelty conflicts).

4524 * typeck.c (build_chill_modify_expr): Simplify.
4526 Sun Mar 27 19:30:25 1994 Bill Cox (bill@rtl.cygnus.com)

4560 Wed Mar 23 13:34:18 1994 Bill Cox (bill@rtl.cygnus.com)
4562 * expr.c (build_generalized_call): Revert previous change.
4563 To do this correctly, we need a new parsing mechanism, and

4585 * configure: Generate better .gdbinit files.
4587 Tue Mar 22 11:59:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
4589 * actions.c (check_range): Don't emit dynamic checks
4590 if not current_function_decl.

4615 type explicitly. Do that.
4616 * satisfy.c (safe_satisfy_decl): Correct range-checking code.
4618 Mon Mar 21 16:25:07 1994 Bill Cox (bill@rtl.cygnus.com)

4628 * typeck.c (layout_chill_range_type): Instead of tree_int_cst_lt
4629 use compare_int_csts (which is more robust when signedness differs).

4633 * expr.c (chill_expand_expr): Code to expand SET_IN_EXPR,

4635 conversions (because we're now using build_chill_function-call).
4636 * actions.c, decl.c, expr.c, grant.c, parse.y, typeck.c:
4637 Use SET_IN_EXPR in place of IN_EXPR.
4639 * expr.c (build_compare_discrete_expr), ch-tree.h: New function,
4640 with code moved from build_compare_expr.
4641 * expr.c (build_compare_expr): Re-enable compatibility test.

4668 to be compatible with the N-value class, with suitable M and N.
4669 * typeck.c (build_chill_slice): Don't smash a void TREE_TYPE.

4672 * expr.c (build_compare_expr): Fix thinko. Add save_exprs.
4674 * expr.c (build_compare_expr): Fix a transcription bug
4675 (for converting NULL INSTANCEs). Also #include convert.h.

4679 * expr.c (finish_chill_binary_op): Moved code dealing with
4680 the comparison operators from here ...
4681 * expr.c (build_compare_expr): ... to new function here.

4686 * typeck.c (valid_array_index_p): Various cleanups,

4706 to have consistent operand types.
4707 * typeck.c (valid_array_index_p): Change interface to pass
4708 validity conditions back on caller's TREE_LIST. We
4709 cannot link the conditions to anything which a
4710 layout_type routine will expand, since that will occur
4711 before the exception handler is set up.
4712 Change calls to valid_array_index_p also.
4714 Fri Mar 18 14:40:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
4716 * actions.c, except.c, loop.c, tasking.c: Call

4722 function build_unary_op (e.g. by calling build1 directly).
4724 * typeck.c (chill_equivalent): Change to force failure
4725 for non-matching integral types (even if not ranges).
4727 * typeck.c, ch-tree.h (build_chill_slice): Make non-static.
4728 * expr.c (varying_to_slice): Call build_chill_slice (and not
4729 build_chill_slice_with_length, which does bunches of range
4730 checking and does not allow the length to be zero).
4731 * convert.c (convert): Fix off-by-one error.
4732 * actions.c (chill_expand_array_assignment): Minor cleaning up.

4737 take *two* pointer parameters, not one.

4739 if TYPE_SIZE is 0 (i.e. type hasn't already been laid out).
4740 * typeck.c (build_chill_slice_with_length): Fix Bill's previous fix.

4751 * typeck.c (build_chill_slice), expr.c (chill_expand_expr
4752 [case CONCAT_EXPR]): Remove kludge setting slice size upper bound
4753 in TYPE_LANG_SPECIFIC, and restore kludge setting it in MAX_VALUE.
4754 * typeck.c (build_chill_slice): Use TYPE_MAX_VALUE of
4755 array_type if needed for size upper bound of slice_type.
4756 * expr.c (build_concat_expr): Improve calculation of size upper bound.
4758 * typeck.c (valid_array_index_p): Check compatibility using
4760 * typeck.c (build_chill_slice_with_length); For now revert
4761 calling valid_array_index_p on length. (It makes it harder
4762 to realize when the slice is constant length.)
4763 * expr.c (build_chill_indirect_expr): Minor tweak. (This
4764 seems to work around a weird C compiler bug. ??)
4766 * expr.c (build_chill_function_call): Cleanup so it doesn't
4767 call build_function_call (in c-typeck.c).
4768 * typeck.c, expr.c: Use build_chill_function_call instead of
4769 build_function_call (in c-typeck.c).
4771 * parse.y (discrete_mode): Move some of the rules from
4772 non_array_mode into new non-terminal.
4773 (arrayindex): Use discrete_mode (with NAME and TYPENAME) to
4774 avoid some misparses.
4775 * ch-tree.h (SLICE_PTR, SLICE_LENGTH): Removed; unused.
4776 * convert.c (digest_structure_tuple): Add missing parameter.
4777 * decl.c (comptypes): Remove unused prototype.
4778 * decl.c (build_chill_function_type): Handle NULL return_type
4779 correctly (convert to void_type_node).
4780 * decl.c (init_decl_processing): layout boolean_type_node *after*
4781 we've set it's TYPE_MIN_VALUE and TYPE_MAX_VALUE.
4783 Wed Mar 16 16:08:22 1994 Bill Cox (bill@rtl.cygnus.com)

4786 * convert.c (convert): Correct calculation of padding length.
4787 * decl.c (grok_chill_fixedfields): Move ignore_exprs test to
4788 parse.y where it belongs. This permits the removal of a kludge
4789 in make_process_struct.

4802 * ch-tree.h: Fix prototype for valid_array_index_p.
4803 * expr.c (chill_expand_expr): Call build_chill_array_ref to get
4805 (build_hill_lower, build_chill_upper): Return value now inherits
4806 the novelty of the input parameter.
4807 (varying_to_slice): Use CH_NOVELTY macro rather than calling
4808 chill_novelty directly.
4809 * grant.c (newstring): Make len unsigned and cast xmalloc parameter
4811 (print_integer_type): Pass string value as APPEND's second parameter.
4812 (decode_decl): Pass a boolean expression as print_proc_tail's
4814 (chill_finish_module_code): Make xmalloc's parameter unsigned.

4853 * decl.c (finish_chill_function, finish_decl): Provide the
4854 new permanent_allocation flag.

4886 * tasking.c (make_process_struct): Force ignore_exprs non-zero
4887 when processing a SEIZEd PROCESS declaration. This prevents
4888 grox-fixed_fields from returning a NULL, and indirectly protects

5042 Wed Feb 23 15:07:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
5044 New cleaner solution to the following problem:
5045 Chill allows an action to be followed by an ON-handler.
5046 But we don't know if an action has a handler until we've parsed
5047 its end, yet we want to generate extra code to set up an
5048 exception handling contour only if needed. The old solution
5049 would generate code for the action into an rtl sequence, and then
5050 splice in the exception-setup code if we later found we needed it.
5051 This has a few problems (for example it confuses the management
5052 of stack temporaries), and is ugly. Now that the compiler is 2-pass
5053 we have a cleaner solution: In pass 1, we remember which actions
5054 were followed by ON-handlers. In pass 2, we use this information
5055 to generate appropriate code before an action.
5056 * except.c (push_handler, pop_handler): In pass 1, set up data
5057 structures (global_handler_list) to remember if an action has an
5058 ON-handler. In pass 2, digest this information, and setup
5060 * except.c, actions.h (pop_handler): Take an extra int arg.
5061 * except.c (emit_setup_handler): New function, with code (moved
5062 from chill_start_on) to emit code before an action that has a handler.
5063 * except.c (except_init_pass_2): New function.
5064 * parse.y (pass1_2): Call except_init_pass_2 before pass 2.
5065 * parse.y (POP_UNUSED_ON_CONTEXT): Don't call pop_sequence.
5066 * parse.y: Invoke POP_UNUSED_ON_CONTEXT and POP_USED_ON_CONTEXT
5067 in pass 1 as well as pass 2.
5068 * parse.y (BEGIN ... END): Re-arrange logic to avoid block_stack
5069 (local to ../stmt.c) getting out of sync.
5070 * actions.c (push_action): Don't need to emit a NOP,
5071 now that we're no longer moving sequences around.
5072 * actions.c (push_action): Call push_handler even in pass one.
5074 Wed Feb 23 11:06:14 1994 Bill Cox (bill@rtl.cygnus.com)

5177 * typeck.c (build_chill_array_type): Update accordingly.

5181 * convert.c (convert): The same.
5183 * grant.c (decode_constant): Clean up. Remove remnants of switch

5799 convert_float, convert_number): Set CH_DERIVED_FLAG for literals.
5800 * ch-expr.c (finish_chill_binary_op): Use convert_to_class.
5801 * ch-satisfy.c (safe_satisfy_decl): For CONST_DECL, make sure
5802 DECL_INITIAL gets set to result of convert.
5803 Also, clear CH_DERIVED_FLAG for SYN value.
5804 * expr.c (store_constructor): If a [power]set is exactly one
5805 word long, use single-word move.
5807 Sat Jan 8 08:38:29 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5809 * c-typeck.c (chill_initializer_constant_valid_p): Fix typo.

5813 * ch-typeck.c (build_chill_slice_with_length): Test that ARRAY is of
5814 ARRAY_TYPE before assuming so. Also, subtract 1 from LENGTH in
5815 computation of SLICE_END.

5819 * ch-expr.c (build_chill_indirect_ref): Handle MODE == NULL_TREE.
5821 * ch-expr.c (fold_set_expr): Handle OP1 == NULL_TREE (which happens
5822 for unary set operations).
5824 * ch-expr.c (build_chill_array_expr): Take new argument FORCE. All
5825 callers changed. All callers changed.
5827 * ch-convert.c (digest_structure_tuple): Handle SELECTED_VARIANT
5828 being NULL_TREE until we've started walking the list of values via
5829 the loop over VARIANTs.
5831 * ch-parse.y (build_chill_constructor): If we see an IDENTIFIER_NODE,
5832 treat it as an enum value (and hence constant). Also, only set
5833 TREE_STATIC if the constructor is indeed constant.
5834 * c-typeck.c (chill_initializer_constant_valid_p): If we see a
5835 VAR_DECL, test the TREE_CONSTANT field of the DECL_INITIAL, don't
5836 recurse on the DECL_INITIAL.
5838 Wed Jan 5 01:24:50 1994 Bill Cox (bill@cygnus.com)
5840 * Makefile.in: Add CHILL to LANGUAGES variable.
5841 * ch-actions.c (check_range): Call build_binary_op instead of
5842 fold, build to get the common types chosen.
5843 (cond_range_exception, cond_overflow_exception,
5844 cond_type_range_exception): Delete, obsolete.
5845 (chill_convert_for_assignment): Enable this, get particular
5846 about when to generate rangecheck code.
5847 * ch-expr.c (build_chill_function_call): Sketch in where to
5848 perform chill_convert_for_assignment on actual parameters.
5849 (build_chill_addr_expr): Correct compiler warning.
5850 * ch-loop.c (build_chill_iterator): Add runtime check for
5851 negative loop step expression.
5852 * ch-tree.h: Add prototype.
5853 * ch-typeck.c (chill_max_vary_array_ref): Correct misunderstanding.
5854 A varying array's length field counts the NUMBER of active array
5855 array entries, not the byte-length of them.
5857 Tue Jan 4 17:57:39 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5859 * ch-decl.c (do_decl): Call `suspend_momenary' if the
5860 converted constructor must live on the permanent_obstack.
5861 * ch-convert.c (convert): When building a new SET_TYPE
5862 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5863 * c-typeck.c (chill_initializer_constant_valid_p): Handle VAR_DECLs.
5865 * ch-typeck.c (chill_location): CONSTRUCTORS that are static

5868 on permanent_obstack if necessary.
5870 * ch-convert.c (digest_structure_tuple): When building a new SET_TYPE
5871 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5873 * ch-decl.c (do_decl): Fix handling of REFERENCE_TYPEs which
5874 the patch below helped to mess up.
5876 * ch-expr.c (build_chill_arrow_expr): Call `mark_addressable'.
5877 (build_chill_addr_expr): Take new argument ERRORMSG.
5878 All callers changed. Also, call `build_chill_addr_expr' where
5879 we used to call `build1 (ADDR_EXPR, ptr_type_node, ...)' since
5880 that now calls `mark_addressable' automagically.
5882 * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.
5883 This is needed because variables may appear in initialization
5884 statements, and their DECL_INITIALs are their values at
5885 initialization time.
5886 * ch-convert.c (digest_structure_tuple,digest_constructor): Changed
5887 to handle VAR_DECLs as initializers.
5889 * ch-convert.c (digest_structure_tuple): Copy elements of INITS so
5890 they aren't destroyed for later use.
5892 Tue Jan 4 15:25:30 1994 Bill Cox (bill@cygnus.com)
5894 * ch-expr.c (chill_expand_expr): Correct check-range lo_limit
5895 parameter for varying_array_ref calculations.
5896 (build_chill_indirect_ref): Prevent seg fault due to syntax error.

5898 of bogus error in votrics.
5899 (build_chill_slice_with_length): Change for debug tracability.

5903 * ch-convert.c (digest_structure_tuple): Fix phasing problem in
5904 handling variant record initializers.
5905 (various places): Change `pop_init_level' calls to match
5906 `push_init_level' wrt implicit variable.
5908 * ch-typeck.c (build_chill_slice): Convert the dynamic max index to
5909 `integer_type_node' before using it in comparisons. FIXME: should
5910 this be done in `chill_max_vary_array_index' by default?
5912 Tue Jan 4 00:24:14 1994 Bill Cox (bill@cygnus.com)
5914 * ch-actions.c: Fix comments.
5915 * ch-parse.y: Define caseaction_flag.
5916 (caseaction): Create new caseaction_flag node at the start,
5917 then free it at the end. Check it before the ELSE code.
5918 (expanded_case_label): Check the flag here. If set in either
5919 place, generate a jump to the end of the case.
5920 * ch-typeck.c (build_chill_slice_with_length,
5921 build_chill_slice_with_range): Add lots of compile-time
5922 parameter range checking.
5924 Mon Jan 3 21:49:04 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5926 * ch-convert.c (digest_structure_tuple): Call `push_init_level' with
5927 implicit==0 everywhere, not 1.
5928 (digest_constructor): Ditto.
5930 * ch-actions.c (check_range): Permit limits to be NULL_TREE.
5931 Also, hack out some dead code.
5932 * ch-typeck.c (build_chill_slice): Check varying and non-varying
5933 slice constructs for range failures.
5934 (build_chill_slice_with_range): Reindented, but not changed.
5936 * ch-typeck.c (chill_max_vary_array_index): New function.
5937 * ch-expr.c (chill_expand_expr): Call it.
5939 * ch-decl.c (var_data_id, var_length_id): New variables.
5940 (init_decl_processing): Initialize them. All calls to
5941 get_identifier (VAR_LENGTH or VAR_DATA) are now replaced
5942 by references to these variables. This simplifies the code
5943 w/o obscuring anything.
5945 Mon Jan 3 21:24:44 1994 Bill Cox (bill@cygnus.com)
5947 * c-typeck.c: Fix comment.
5948 * ch-actions.c (chill_expand_assignment): Error assigning to
5949 READONLY location. (PR_3903) Pass filename, linenumber
5950 to setbitpowerset runtime routine.
5951 * ch-decl.c (init_decl_processing): Add filename, linenumber
5952 parameters to setbitpowerset prototype.
5953 * ch-expr.c (build_chill_function_call): Error when passing a
5954 READonly location as a LOC or INOUT parameter.
5955 * ch-parse.y (mode): Correct code marking type as readonly.
5957 Mon Jan 3 19:03:55 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5959 * ch-actions.c (chill_expand_assignment): Disable code that defeats
5960 building varying array references.
5961 * ch-expr.c (chill_expand_expr): Add rangecheck code to
5962 VARY_ARRAY_REF case.
5963 * ch-typeck.c (build_chill_array_ref): Don't call an `expand_'
5964 function (in this case, `validate_varying_array_ref') when we're
5965 doing a `build_' operation.
5967 * ch-typeck.c (validate_varying_array_ref): Simplify interface
5968 since INDEX parameter can never meaningfully be an INDEXLIST.
5969 * ch-actions.c (expand_varying_length_assignment): Caller changed.
5971 Mon Jan 3 07:29:45 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5973 * ch-typeck.c (build_chill_cast): Set TREE_CONSTANT on NOP_EXPRs.
5974 * ch-convert.c (digest_structure_tuple): Switch to permanent_obstack
5975 if we need to build a CONSTRUCTOR for a SET_TYPE initializer.
5976 (digest_structure_tuple): If TREE_VALUE (VALUE) == NULL_TREE, don't
5977 call CH_COMPATIBLE or try to convert it to TREE_TYPE (FIELD). This
5978 can happen when constructors are output incrementally.
5979 * c-typeck.c (initializer_constant_valid_p): Handle SET_TYPEs.
5980 * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
5983 Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5985 * ch-convert (digest_structure_tuple): Handle SET_TYPEs. Also, call
5986 `convert' so we can handle INSTANCE types (and other anomolies)
5989 * ch-convert.c (digest_structure_tuple): Fixed variant
5990 structure initialization. Also fixed a typo (TYPE_NAME
5991 was being used on a FIELD_DECL instead of DECL_NAME).
5992 * c-typeck.c (initializer_constant_valid_p): Pass missing
5993 ENDTYPE argument on recursive call.
5994 (set_init_field): New function, needed by ch-convert.c change above.
5996 * ch-decl.c (layout_chill_variants): Added a FIXME next to an
5997 almost certain typo.
5999 * ch-expr.c (build_chill_arrow_expr): Call `build1' and set
6000 TREE_CONSTANT for static references.
6001 * ch-except.c (chill_start_on): Change calls to
6002 `build_unary_op' (which is C-specific) to `build_chill_arrow_expr'
6003 which has CHILL semantics.
6004 * ch-convert.c (convert): Ditto (albeit in some disabled code).
6006 Sat Jan 1 21:26:43 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6008 * ch-satisfy.c (safe_satisfy_decl): Reorder conditional test of
6009 TREE_CODE of DECL in case it's altered by actions in the switch.
6011 * ch-satisfy.c (satisfy): Undo abort added earlier on 1 Jan. CVS log
6012 mentions where to find code that triggers this case.
6014 * ch-actions.c (adjust_parm_or_field): Handle CONSTRUCTORS here as
6017 * ch-convert.c (digest_structure_tuple): Push to permanent_obstack if
6018 we're dealing with a CONSTRUCTOR that is TREE_PERMANENT.
6019 (digest_constructor): Ditto.
6021 Sat Jan 1 10:29:19 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6023 * ch-parse.y (handleraction,resultaction,assignaction,call): Modified
6024 so that CONSTRUCTORS are properly handled before being used.
6026 * ch-convert.c (chill_start_init): New function. All callers to
6027 `start_init' changed to call this function instead.
6028 (digest_struct_tuple): Defend against initialization machinery
6029 mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
6030 IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
6031 needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
6032 can be refered to throughout the compilation unit. Also remove an
6033 extraneous call to `process_init_element' erroneously added to the
6034 variant record sub-loop.
6035 (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
6036 CONSTRUCTORS of SET_TYPE.
6037 * ch-parse.y (build_chill_constructor): Refix typo. Also set
6038 TREE_STATIC if at top level.
6040 * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
6041 TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
6042 should have been called.
6044 * ch-convert.c (digest_struct_tuple): Restore code which tracks
6045 field initializations so that the compiler can deduce what variant
6046 initializations to assume.
6048 * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
6049 when we push into a scope that has a DECL with a CONSTRUCTOR as its
6052 * ch-parse.y (build_chill_constructor): Change the name of the
6053 parameter to something more meaningful. Fix typo. Also, handle case
6054 where element is an untyped CONSTRUCTOR.
6056 * ch-except.c (finish_handler_array): Set TREE_CONSTANT on
6057 constant ADDR_EXPRs.
6058 (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT
6059 on JBUF_REF (instead of calling `build1' which does not).
6061 * ch-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
6063 * ch-typeck.c (chill_expand_tuple): Deleted.
6064 * ch-parse.y (primval rule): Don't call `chill_expand_tuple';
6065 instead, use initialization machinery for CONSTRUCTORS that
6067 * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
6068 that are created here.
6069 * ch-satisfy (satisfy): Abort in case we would have called
6070 chill_expand_tuple. FIXME: some other code is needed here,
6071 but I don't know what yet.
6073 * ch-parse.y (build_chill_constructor): New function to
6074 propagate TREE_CONSTANT bits to CONSTRUCTORS.
6075 (untyped_expr rule): Use it.
6076 (primval rule): Use it.
6078 * ch-decl.c (do_decl): Call `finish_init'.
6079 * ch-convert.c (convert): If we spontaneously create a CONSTRUCTOR in
6080 this function, make sure the initialization machinery is set up.
6082 * ch-convert.c (digest_structure_tuple, digest_constructor): Add
6085 Fri Dec 31 11:31:01 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6087 * ch-grant.c (chill_finish_module_code): Mark ADDR_EXPR built by hand
6088 as being TREE_CONSTANT. Otherwise it gets bounded by the initializer
6091 * ch-decl.c (do_decl): Change in CONSTRUCTOR handling due to...
6092 * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
6093 rewritten to work with GCC's initialization code. The basic change
6094 was to keep the initializers in sync with the initialization
6095 machinery that `process_init_element' imposes. Both of these
6096 functions now return `void'.
6097 * ch-convert.c (convert): Changed calls to `digest_...' functions.
6099 FIXME: the code handling UNION_TYPE (and variant records) has not
6102 Fri Dec 31 15:32:56 1993 Bill Cox (bill@rtl.cygnus.com)
6104 * ch-lex.l (convert_number): Output the converted number if
6106 * ch-parse.y (signaldef): Set ignore_exprs correctly for a
6109 Fri Dec 31 13:17:48 1993 Bill Cox (bill@cygnus.com)
6111 * ch-parse.y: Cleanup handling of RETURN actions, to distinguish
6112 a RETURN without a value (which cannot have an exception
6113 handler) from a RETURN with a value (which can). Eliminate
6114 some shift/reduce and reduce/reduce conflicts.
6116 Thu Dec 30 17:42:32 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6118 * ch-inout.c (build_chill_writetext): Deal with 2 cases where
6119 types returned from `type_for_size' are not expected. FIXME.
6120 * ch-decl.c (init_decl_processing): Mark `char_type_node' unsigned.
6121 This is required when range checking is enabled.
6123 Thu Dec 30 14:28:25 1993 Bill Cox (bill@rtl.cygnus.com)
6125 DELAY CASE works now.
6126 * ch-decl.c (init_decl_processing): Move rest of tasking-related

6129 (optsetprio): New non-terminal.
6130 * ch-tasking.c (get_task_name): Delete, obsolete.

6137 correct its functioning.
6138 (build_delay_case_end): Correct the code.
6139 (tasking_init): Lots of tasking-related code moved here from
6140 init_decl_processing.

6146 failed full regression testing.
6147 * ch-lex.l (name_type_signal): Add debug output.
6148 * ch-parse.y (structured_variable): Add a debug variable.
6150 Wed Dec 29 02:05:51 1993 Bill Cox (bill@rtl.cygnus.com)
6152 * ch-decl.c (get_next_decl): Revert change which failed full
6155 Tue Dec 28 18:20:14 1993 Bill Cox (bill@rtl.cygnus.com)
6157 DELAY actions work now.
6158 * ch-decl.c: Correct spelling in comments.
6159 (get_next_decl): NULL out the decl's TREE_CHAIN before returning
6160 it, to prevent accidental access to the remembered_decls.
6161 (init_decl_processing): Add wait_event to runtime functions.
6162 * ch-expr.c (build_chill_indirect_ref): Prevent a syntax error from
6163 becoming a seg fault.
6164 * ch-grant.c: Correct a comment.
6165 * ch-loop.c: Delete/correct comments.
6166 * ch-parse.y (delaycaseaction): Add push/poplevel calls. Turn 'sorry'
6167 into rough draft of actual code.
6168 (delayaction): Don't make a new scope here, use get_unique_identifier
6170 (locdec): process event decls here, too.
6171 (mode): Add code to forbid READonly EVENT and BUFFER decls. Delete
6172 code which required EVENTs and BUFFERs to be declared at global scope.
6173 (simple_name_string): Add an EVENTNAME.
6174 * ch-satisfy.c (safe_satisfy_decl): Prevent a syntax error from
6175 becoming a seg fault.
6176 * ch-tasking.c (tasking_setup): Add the event queue's max. length
6177 as the 'entry_point' parameter in the list.
6178 (build_receive_case_start, build_receive_case_label): Defer
6179 calling runtime routine until we know whether we have a signal
6180 or a buffer to wait for.

6189 * gcc.c (CHILL SPECS): Delete references to -M -MM -MD -MMD
6190 options. Delete C-specific defines. Disable piping from
6191 pre-processor to cc1chill (even if -pipe is specified), since cc1chill
6192 rewinds its input for its second pass. Piping still works
6193 from cc1chill to as.
6195 Thu Dec 23 12:31:55 1993 Bill Cox (bill@rtl.cygnus.com)
6197 * ch-tasking.c (decl_tasking_code_variable): Assure that the
6198 tasking_code variable is allocated on the permanent obstack.
6199 (tasking_setup): Lots of changes - handle EVENT/BUFFER max.
6200 queue length (passed as the entry_point parameter).
6201 Other changes to variable names to increase 'self-documentation'
6202 the only kind GNU CHILL will get, for a while..
6204 Wed Dec 22 10:46:31 1993 Bill Cox (bill@rtl.cygnus.com)
6206 * ch-decl.c (do_seize): Delete - it's unused. Fix comments.
6207 * ch-loop.c (build_chill_iterator): Convert BY expression
6208 so loop involving a SET works. Additional errors generated
6209 for numbered SET expression as start or end expression.
6210 * ch-tree.h: Prototypes for future DELAY functions.
6211 * ch-typeck.c: Standard indentation.
6213 Tue Dec 21 15:30:57 1993 Per Bothner (bothner@kalessin.cygnus.com)

6225 Also check that ranges have the same bounds.
6226 * ch-typeck.c (my_build_array_ref): Add optional range-checking.
6227 * ch-typeck.c (chill_location): Handle COMPOUND_EXPR properly.
6228 Return 2 if also a referable.
6229 * ch-typeck.c (chill_referable): Re-define to use chill_location.
6230 * ch-tree.h (CH_EQUIVALENT): Re-defined to use chill_equivalent.
6232 * dbxout.c (dbxout_type): Output the type attribute "@S;" to
6233 distinguish a string from a char array, and to distinguish a
6234 bitstring from regulat (power)set. (Needed for Chill.)
6235 * dbxout.c (dbxout_type): Only check for baseclasses in
6236 type.binfo is a vector. (It is used in Chill for tagged unions.)
6238 Fri Dec 17 09:56:07 1993 Bill Cox (bill@rtl.cygnus.com)
6240 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
6241 ch-grant.c, ch-inout.c, ch-loop.c, ch-parse.y,
6242 ch-satisfy.c, ch-tasking.c, ch-tree.h, ch-typeck.c:
6244 * ch-actions.c (chill_expand_assignment): Error if assigning

7035 error message in pass 1.

7044 parameter to know whether to include an init expression.

7254 for example, as the module-level code's name.
7255 * ch-loop.c (build_temporary_variable, begin_for_range,
7256 init_loop_counter): Add parameter to decl_temp1 call.
7257 * ch-parse.y (quasi_signaldef): Clear quasi_signal flag here,

7307 * ch-parse.y (end_function): Use DECL_ARGUMENTS to check
7308 for parameterless process.
7310 Fri Oct 1 13:57:30 1993 Per Bothner (bothner@kalessin.cygnus.com)
7312 * ch-typeck.c (chill_location): New function.
7313 Based on lvalue_p, but also handle Chill-specific VARY_ARRAY_REF.
7314 * ch-typeck.c, ch-tree.h (CH_LOCATION_P), ch-convert.c: Use
7315 chill_location instead of lvalue_p.
7318 Fri Oct 1 11:28:42 1993 Bill Cox (bill@cygnus.com)
7320 * ch-convert.c (convert): Back out Michael's changes, unintentionally
7322 * ch-lex.l (handle_use_seizefile_directive): No longer downcase

7334 ch-convert.c (convert): Use it.
7335 * ch-typeck.c (build_chill_slice): Take length rather than upper
7336 bound. This makes it easier to recognize that A(X UP LENGTH)
7337 really has fixed length. Also, if the argument is string,
7338 mark the slice as a string too. Also, handle varying strings.
7340 * ch-typeck.c (conflate_singleton_strings): New global.
7341 * ch-typeck.c (chill_similar): If conflate_singleton_strings is
7342 set (as it currently is), allow CHARS(1)/BOOLS(1) to be similar
7343 to CHAR/BOOL, as required by the 1984 version of Z.200.
7344 * ch-convert.c (convert_to_char): Convert CHARS(1) to CHAR.
7345 * ch-convert.c ( build_array_type_for_scalar): If input is string,
7347 * ch-convert (maybe_turn_scalar_into_arra), ch-tree.h: Removed.
7348 * ch-convert.c (convert): Convert CHAR to CHARS(1).
7350 This fixes 'X // := Y' and is also a general simplification.
7351 * ch-actions.c (chill_expand_assignment): Convert 'LHS OP := RHS'
7352 to 'LHS := LHS OP RHS' (using stabilize_reference on LHS).
7353 Also, call save_expr on RHS if a multiple assignment.
7354 * ch-parse.y (assignaction): Therefore, no longer need to call
7355 stabilize_reference on RHS.
7356 * ch-typeck.c (build_chill_modify_expr), ch-tree.h: Remove
7357 modifycode parameter. Make it the caller's responsibility to
7358 handle <assigning operator>.

7360 ch-loop.c: Fix calls to build_chill_modify_expr accordingly.
7362 Wed Sep 29 18:02:55 1993 Per Bothner (bothner@kalessin.cygnus.com)
7364 * ch-lang.c (string_index_type_dummy), ch-tree.h: New variable.
7365 * ch-decl.c (integer_minus_one_node), ch-tree.h: New variable.
7367 * ch-parse.y (arrayindex: modename): Remove useless code.
7368 * ch-satisfy.c (satisfy): Don't gag on string_index_type_dummy,
7369 * ch-tree.c (build_string_type): Pass string_index_type_dummy as
7370 the parent type of the index range.
7371 * ch-typeck.c (layout_chill_range_type): Recognize and handle
7372 string_index_type_dummy - specifically allow an empty range.
7374 Wed Sep 29 13:36:23 1993 1993 Bill Cox (bill@cygnus.com)
7376 * ch-convert.c (convert_to_reference): Check for loc-identity
7377 mismatches correctly (and remove one of those chill_compatible
7379 * ch-decl.c (decl_tasking_code_var): New function, called from
7380 push_extern_process and push_extern_signal.
7381 * ch-parse.y (end_function): Delete parameter. Check current_function_decl
7382 whether it's actually a process, and whether it has parameters.
7383 Make Michael's change simplifying the pass 2 test, preventing a seg
7385 (procedure, process): Change calls to end_function, remove
7386 code saving value from build_process_header. Delete redundant chill_
7387 phrases from some function calls.
7388 * ch-tasking.c: Remove some redundant _chill phrases from function
7390 * ch-tree.h: Remove some redundant _chill phrases from function
7391 names. Add the CH_VARYING_ARRAY_TYPE macro, call it from
7392 all relevant places.
7393 * ch-typeck.c: Use the new macro. Cast TREE_CODEs to chill_tree_code.
7395 Wed Sep 29 13:07:43 1993 Per Bothner (bothner@kalessin.cygnus.com)
7397 * ch-convert.c (convert_to_reference): Remove redundancies.

7399 with a recursive convert call.
7400 * ch-decl.c (do_decl): Add missing compatibility-checking
7401 of initializer (don't depend on convert).
7403 Tue Sep 28 00:02:25 1993 Per Bothner (bothner@kalessin.cygnus.com)
7405 * ch-tree.h (CH_LOCATION_P): New macro.
7406 * ch-typeck.c (layout_chill_range_type): Fix call to
7407 type_for_size, when figuring out a defaulted parent type.
7408 * ch-expr.c (build_chill_lower, build_chill_sizeof): Check
7409 for TREE_CODE_CLASS != 't' rather than == 'd'.
7410 * ch-expr.c (build_chill_function_call): Use CH_LOCATION_P
7411 to check for location, rather than TYPE_CODE_CLASS == 'd'.
7413 * ch-tree.c (build_string_type): Make 2-pass safe. Also,
7414 change parameter to be length, not index type.
7415 * ch-parse.y (mode2), ch-expr.c (build_concat_expr), ch-lex.l
7416 (build_chill_string): Modify callers of build_string_type accordingly.
7417 * ch-lex.l (check_newline): Don't look for # directive inside a
7419 * ch-grant.c (grant_array_type): Make more robust for char-
7420 and bit-strings (allow non-constant sizes). Change parameters
7421 and return types. (raw_decode_mode): Use grant_array_type
7422 for bitstrings. (otherwise): Fix grant_array_type callers.
7424 Mon Sep 27 16:57:57 1993 Per Bothner (bothner@kalessin.cygnus.com)
7426 Remove changes of Sep 15.
7427 * ch-tree.h (CH_SINGLETON_DOMAIN): Removed.
7428 * ch-typeck.c (chill_similar): Don't allow a singleton
7429 powerset to be similar to its domain.
7430 * ch-convert.c (convert_to_boolean): Don't convert a singleton
7431 SET_TYPE constructor to a Boolean.
7433 * ch-actions.c (chill_expand_assignment): Handle IN_EXPR on
7434 LHS of assignment, which is what we're current (temporarily?) using.
7436 Mon Sep 27 06:01:57 1993 Bill Cox (bill@rtl.cygnus.com)
7438 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
7439 ch-grant.c, ch-inout.c, ch-parse.y, ch-satisfy.c,
7440 ch-tasking.c, ch-tree.c, ch-tree.h, ch-typeck.c:
7441 -Wall cleanup. Add prototypes where missing.
7442 Delete unused variables. Cast uses of tree_codes
7443 to chill_tree_code, which they are.
7445 Sun Sep 26 13:09:57 1993 Bill Cox (bill@rtl.cygnus.com)
7447 * ch-decl.c (do_decl): Save initializer in pass zero
7449 * ch-lex.l: Fix comments, indentation.
7450 * ch-parse.y: Standardize error messages to use

7452 Suggestion from docs department.
7453 * ch-tasking.c: Pervasive changes to get processes to
7455 * ch-tree.h: Delete prototypes for functions whic
7456 I made static inside ch-tasking.c.
7458 Sun Sep 26 02:40:02 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7460 * ch-lex.l (yywrap): Call `check_newline' in case the file
7461 started with a line directive.
7463 Sat Sep 25 13:54:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
7465 * ch-decl.c: Expand pre-amble comment.
7466 * ch-decl.c (struct scope, push_module): Use new field
7467 tail_chain_module to build child-module list in order.
7468 (Just to make compiler debugging a little less confusing.)
7470 * ch-decl.c (struct scope): New field weak_decls.
7471 * ch-decl.c (find_implied_types): New interface. Now pre-pend
7472 new enum types to a given input list. This makes it easier to
7473 avoid duplicates, which should at least be more efficient.
7474 Also, handle FUNCTION_DECL.
7475 * ch-decl.c (bind_saved_names): Removed. Distribute its
7476 functionality over new functions (push_scope_decls, pop_scope_decls,
7477 build_implied_names, bind_sub_modules). The goal (which seems to
7478 have been more-or-less attained) was to fix weak name handling.
7479 * ch-decl.c (poplevel): Use new function pop_scope_decls.
7481 * ch-tasking.c (build_signal_struct, build_tasking_message_type):
7482 Use build_decl directly, rather than grok_chill_fixedfields
7483 (which depends on ignore_exprs and has more overhead).
7484 * ch-tasking.c (build_signal_struct): Construct the type
7486 * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
7487 than build_array_ref (which does C-specific "optimizations").
7488 (Hence move my_build_array_ref up earlier in the file.)
7490 Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7492 * ch-tasking.c: Declare static variable `void_ftype_void'.
7493 (chill_tasking_init): Initialize `void_ftype_void' here.
7494 (build_tasking_struct): Use, don't declare `void_ftype_void'.
7495 (generate_tasking_code_variable): Call `do_decl', not
7496 `decl_temp1' to declare TASKING_CODE_NAME.
7497 (tasking_setup): Drop into 1-pass mode so that all
7498 tasking-related declarations are installed in the global
7499 scope. Use correct CHILL types for initializers (since
7500 ptr_type_node doesn't have the right meaning for CHILL).
7501 Also, call `do_decl' instead of `decl_temp1' for
7503 (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
7504 `chill_finish_compile' in sync between passes.
7506 * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
7507 declarations on pass zero. Keep obstacks in sync, and always
7508 call `finish_decl' for pass zero declarations.
7509 (push_chill_extern_function): Keep obstacks in sync, and always
7510 call `finish_decl' for pass zero declarations.
7511 (build_enumerator): Ditto.
7512 (grok_chill_variantdefs): Change PASS test to exclude only
7514 (finish_struct): Ditto.
7515 * ch-expr.c (build_chill_component_ref): Ditto.
7516 (build_chill_binary_op): Ditto.
7517 * ch-tree.c (build_powerset_type): Ditto.
7518 (build_bitstring_type): Ditto.
7519 * ch-typeck.c (build_chill_range_type): Ditto.
7520 (build_chill_struct_type): Ditto.
7522 * ch-decl.c (build_chill_exception_decl): Clarify reasons for
7523 extra pushing and popping of obstacks.
7525 * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
7526 on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
7528 * ch-grant.c (chill_finish_compile): Clear out both
7529 MODULE_INIT_LIST and TASKING_LIST if either contains stuff
7532 * ch-parse.y (rccase_label): Add NAME rules so that pass one
7533 works w/o knowing we're parsing a signal. Simplify SIGNALNAME
7534 rules since we only get SIGNALNAME tokens in pass two.
7535 (sendaction): Ditto.
7536 * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
7537 BUFFERNAME on pass two. The grammar now handles this.
7538 * ch-decl.c (lookup_remembered_decl): Deleted.
7540 Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
7542 * ch-decl.c (lookup_remembered_names): Removed. It was being
7543 misused in ch-lex.l.
7544 * ch-lex.l (name_type_signal): Revert last change. Basically,
7545 we cannot use the C typedef/variable name trick in CHILL, due
7546 due to the language's 2-pass nature.
7547 * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
7549 * ch-tree.h (lookup_remembered_name): Comment out the prototype.
7551 Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7553 * ch-decl.c (do_decl, push_chill_extern_function): Change pass
7554 checks so the pass == 0 case is handled for built-in types.
7555 (push_modedef): Add check for error_mark_node.
7556 (lookup_remembered_decl): New function.
7557 (pushlevel, poplevel) Change pass checks.
7558 (pushdecl): Check type as well for NULL.
7559 (build_enumerator): Handle pass == 0 case.
7560 * ch-lex.l: Use lookup_remembered_decl to get lastiddecl
7562 * ch-parse.y: Set pass to zero to indicate initial decl processing.
7563 Replace NAME references with SIGNALNAME references.
7564 (startaction): Only check copy number if not ignoring actions.
7565 Always call build_chill_start_process.
7566 (optstartset): Don't lookup the instance name.
7567 * ch-tasking.c (generate_tasking_code_variable): Replace
7568 do_decl call with decl_temp1 call.
7569 (build_chill_start_action): Check for ignore_actions here.
7570 (build_tasking_message_type): Layout the type.
7571 (rc_state_type): New structure to keep nested receive-case
7573 (build_chill_receive_case_start, build_chill_receive_case_end):
7577 Fri Sep 24 04:19:15 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7579 * ch-tasking.c (build_chill_receive_case_start): `namedecl'
7580 should be a _DECL, not an IDENTIFIER_NODE.
7582 Thu Sep 23 18:18:24 1993 Per Bothner (bothner@kalessin.cygnus.com)
7584 * ch-decl.c (find_implied_types): Handle VAR_DECLs.
7586 * ch-decl.c (print_lang_identifier): Print IDENTIFIER_OUTER_VALUE.

7603 ALIAS_DECL the name in the most recent use_seize_file directive.
7604 (This requires that use_seize_file directives written to the
7605 grant file be written before the SEIZEs that need it.)
7606 Allow clashing declarations granted into the global scope
7607 (produce a warning), but remember the seizefile case from
7608 (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
7609 The a SEIZE will select the granted decl that matches its
7610 DECL_SEIZEFILE (in other words: grants from the most recent
7611 use_seize_file will be preferred).

7621 * ch-lex.l (mark_use_seizefile_written): New function.

10299 (start state 'ccitt'): Deleted, unused. Moved unused, but reserved,
10300 tokens to NORMAL state.
10301 (compiler_directive): Replaced by equal_number. Now the only
10302 recursive call to yylex happens in check_newline at the beginning
10305 Sat Apr 10 09:55:50 1993 Bill Cox (bill@rtl.cygnus.com)
10307 * ch-actions.c (build_chill_case_expr): Added from ch-parse.y.
10308 * ch-lex.l (ENTRY, PERVASIVE, ROW, STEP): Add token recognition to
10310 * ch-parse.y (case_expr): Move code into ch-actions.c. There will

10313 * ch-tree.h (build_chill_case_expr): Add prototype.
10314 * ch-typeck.c (build_chill_cast): Allow untyped_expr - just assign the
10315 type to the expr. Check for CASE_EXPR, call expand_case_expr.
10317 Sat Apr 10 01:10:51 1993 Per Bothner (bothner@rtl.cygnus.com)
10319 * ch-parse,y (in_pseudo_module): New variable. Try if we're
10320 in a seizefile, but not in a module nested in the seizefile.
10321 Use for backwards compatibility with old grantfiles.

10333 * ch-lex.l: Re-write to use start states, to avoid calling
10334 yylex() recursively.
10335 * ch-lex.l (compiler_directive); This is now obsolste. FIXME.
10336 * ch-lex.l: Call push_module and pop_module when reading a
10337 seizefile. This creates a pseudo-module.
10338 * ch-parse.y: Clean up handling of empty declarations and
10339 action statements; semicolons are now optional a number of
10341 * ch-parse.y: Remove some bogus tests for "statement
10342 out of sequence" (they're both legal and work).
10343 * varasm.c (mak_function_rtl): Remove kludge that may
10344 not be necessary (and loses anyway).
10346 Fri Apr 9 09:37:38 1993 Bill Cox (bill@rtl.cygnus.com)
10348 * ch-expr.c (chill_expand_array_assignment): Remove false error about

10365 which is the list (in order) of decls in the module.
10366 Don't reverse the getdecls() list; that is handled by caller.

10384 assignment, clean up.
10385 * ch-typeck.c: Add prototype for require_complete_type.

10395 * ch-decl.c (massage_param_node): New function.
10396 It handles the LOC/IN/OUT/INOUT parameter distinction,
10397 as well as calling build_chill_array_parm_type if needed.
10398 * ch-tree.h (massage_param_node): New prototype.
10399 * ch-decl.c (push_parms): Use new massage_param_node().
10400 * ch-parse.y (pmodearg): Use new massage_param_node().
10401 * ch-parse.y (formpar): Don't call build_chill_array_parm_type;
10402 now handled by massage_param_node.

10409 the pseudo struct type is allocated on the permanent_obstack.
10410 * ch-parse.y (location): Remove thinko.
10411 * ch-actions.c (chill_comptypes): Comment out test for

10424 Mon Apr 5 19:56:56 1993 Bill Cox (bill@rtl.cygnus.com)
10426 * ch-actions.c, ch-decl.c: Use tree_int_cst_equal and integer_zerop

10446 Fri Apr 2 21:55:14 1993 Per Bothner (bothner@rtl.cygnus.com)
10448 Major re-write of New module/seize/grant stuff.
10449 Now, a grantfile is a spec module and contains all the
10450 top-level declarations of the granting module, not just
10451 those that are granted. It also contains explicit grant
10452 statments naming those declared names that are granted.
10453 It also has seize statements and use_seize_file directives
10454 to correctly handle transitive dependencies.
10456 * ch-parse.y: Change to allow multiple modules per source file.
10457 Allow spec modules (including quasi definitions) as well as
10459 Allow spec modules inside normal modules; these behave as if
10460 they were outermost. This violates the Blue Book, but is
10461 needed by the new grantfile mechanism. (A grant file is a
10462 spec module that gets included by the use_seize_file directive.)
10463 * ch-parse.y (struct module *current_module, push_module,
10464 pop_module): Support module nesting (for spec modules only).
10466 * ch-tree.h (struct module): New.
10467 * ch-grant.c (granted_decls): New list of declarations
10468 that have been granted into the outermode pseudo-module.
10469 * ch-grant.c (decode_mode): If the decl has a name,
10470 always write the name, not just if the decl has already
10471 been written. Since we write out all decls, we can assume
10472 it will be written later, and depend on the forward
10473 declaration kludges to catch it.
10474 * ch-grant.c (decode_decl): Don't write out _EXTERN.
10475 Instead write out standard (Blue Book) quasi-definitions.
10476 * ch-grant.c (push_granted): New function.
10477 * ch-grant.c (seize_implied_names): New function. Re-write
10478 how set element names are seized when a set type is seized.
10479 * ch-grant.c (chill_seize): Work by seraching the
10480 granted_decls list and copying the declaration.
10481 * ch-grant.c (chill_grant): Write all declarations
10482 declared in this module. Write GRANT statements for
10483 those granted. seize statements for decls seized from
10484 other modules. Write extra syntax to make a complete
10486 * ch-grant.c (grant_use_seizefile): Copy use_seize_file
10487 directives into grant file.
10488 * ch-lex.l (setup_seizefile_read): Call grant_use_seizefile.
10490 * ch-lex.l (struct input_state, current_input_state,
10491 push_input_file, pop_input_file): New (type, variable,
10492 function*2). Used to save and restore state on an input file.
10493 * ch-lex.l: Clean up to handle nested input seizefiles
10494 (needed by new grant/seize mechanism.
10495 * ch-lex.l (skip_to_end_of_directive): New function.
10496 * ch-lex.l (compiler_directive: USE_SEIZE_FILE): Make sure
10497 we skip to the end of the directive *before* we switch
10499 * ch-lex.l (setup_seizefile_read): Prevent reading the
10500 same seizefile twice (otherwise likely with new grant/seize).
10501 * ch-lex.l: Recognize SPEC. Misc cleanups.
10503 * ch-parse.y: Fixed foreward references of types.
10504 Removed the unknown_type_node crock.
10505 * ch-decl.c: Remove all uses of unknown_type_node.
10506 Check for TYPE_SIZE zero instead.
10507 * ch-decl.c (fixup_unknown_type): Make sure new mode
10508 gets copied into old mode. Merge their variant chains.
10509 * c-decl.c (lookup_name_current_level): Make non-static.
10510 * ch-decl.c (lookup_name_current_level): No longer needed.
10512 * ch-parse.y (call): Allow an implicitly defined function
10513 name following the CALL keyword.
10514 * ch-tree.h (struct lang_identifier): Add implicit_decl,
10515 and make sure order of fields matches c-tree.h.
10517 * ch-actions.c (lang_init, build_allocate_memory_call,
10518 build_allocate_globals_memory_call): Fix names (add initial '_')
10519 and prototypes of _allocate_[global_]memory (2nd param is ref).
10520 Use build_chill_function_call, not build_function_call,
10521 so the reference parameter gets handled.
10522 * ch-actions.c. (lang_init): Make sure boolean_{true,false}_node
10523 have boolean_type_node as their types.
10524 * ch-actions.c (build_chill_lower, build_chill_upper): Fix to
10525 work for arrays with BOOLEAN_TYPE ranges (and simplify some).
10527 * ch-except.c: Make sure an end_label is generated,
10528 and jump to it if there is no exception.
10530 * ch-convert.c (convert_to_reference): Strip off NOP_EXPR casts.
10531 * expr.c (expand_expr): Handle NOP_EXPR as Chill-style casts.
10532 (Need cleaning up and FSF installation!)
10533 * ch-parse.y: If taking the address of a cast, move the
10534 ADDR_EXPR inside the NOP_EXPR.
10536 * ch-typeck.c (my_build_array_ref): Simplified, more suitable
10537 versions of build_array_ref from c-decl.c. (E.g. don't barf
10538 if index type is char or bool.)
10539 * ch-typeck.c (build_chill_array_ref): Use my_build_array-ref.
10541 * ch-typech.c (build_chill_bin_type): New function.
10542 Support BIN(N) range type specification.
10543 * ch-parse.y (mode2), ch-lex.l: Recognize BIN(N).
10545 * ch-tree.h (CH_SIMILAR): Redefine in terms of chill_similar.
10546 * ch-typeck.c (chill_similar): New function. Recognize that
10547 that range types are similar to their parent types.
10549 * ch-tree.h: Declare flag_local_loop_counter.
10550 * ch-loop.c: Whether the loop variable is local to the loop
10551 in now controlled by flag_local_loop_counter, instead of
10552 #ifdef'd on CREATE_SCOPE.
10553 * ch-actions.c (lang_decode_option): Recognize flags
10554 "-f[no-]local-loop-counter".
10555 * toplev.c (lang_options): Add Chill flags -f[no-]local-loop-counter.
10557 * varasm.c (make_function_rtl): Due to problems with forward
10558 references, don't rename nested functions in Chill. (Kudge!)
10560 Sun Mar 28 10:12:45 1993 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10562 * ch-lex.l (push_back, readstring): Fix prototypes.
10564 Fri Mar 26 18:32:15 1993 Bill Cox (bill@rtl.cygnus.com)
10566 * ch-parse.y: Put %type directives back into alpha order.
10567 (variant_alternative): Simplify error_mark test.
10568 (variantfields, varianthack): Add error_mark checks.

10573 * ch-parse.y (get_type_of): Add function to deal with possible fwd
10574 declared type name. Call it from lotsa places. Add lotsa checks

10579 * ch-expr.c (chill_expand_assignment): Avoid seg fault while checking
10580 for array assignments.
10581 * ch-parse.y (action): Add recognition for allocate_memory and
10582 allocate_global_memory system calls.
10583 (mode2): Remove ill-conceived error check that broke REFs to
10584 as-yet-undeclared types. Check for IDENTIFIER_NODE, lookup its
10585 DECL if there, pass TREE_TYPE of decl to build_pointer_type.
10586 (variantfields, varianthack): Clean up.
10587 (variantfield): Check for IDENTIFIER_NODE, lookup its DECL if
10588 there, pass TREE_TYPE of decl to grok_fixedfields.
10589 (labellist): Explicitly assign error_mark_node to signal error.
10590 * ch-typeck.c (chill_compatible): Report FALSE for bad parameters,
10591 rather than seg faulting.
10593 Thu Mar 25 10:35:58 1993 Bill Cox (bill@rtl.cygnus.com)
10595 * ch-actions.c (lang_init): build_function_type for allocate_memory
10596 and allocate_global_memory runtime routines. Move discrete_type_p
10598 * ch-typeck.c (discrete_type_p): Move here, where it belongs, call it

10622 * ch-except.c (start_handler_array): Make sure the handler
10623 array and its type get on the permanent obstack.
10624 * ch-grant.c (write_grant_file): Don't write the _INIT=name
10625 specifier: It isn't needed, and loses (because of funny
10626 characters in the chill_initializer_name).
10627 * ch-decl.c (push_synmode): Set TYPE_NAME(mode) = syndecl.
10628 * ch-lang.c (finish_chill_enum): Don't allocate a dummy
10629 TYPE_DECL for the enum. I don't think it is needed (?),
10630 and removing it is needed for the change above.
10632 * ch-grant.c (grant_array_type, decode_mode): Remove unused
10634 * ch-grant.ch (raw_decode_mode): New function, based on old
10636 * ch-grant.c (decode_mode); This is now just a wrapper around
10637 raw-decode_mode - but does not call raw_decode_mode if the
10638 type is named and has already been emitted.
10640 Fri Mar 19 11:55:35 1993 Bill Cox (bill@rtl.cygnus.com)
10642 * ch-actions.c: Add prototypes, remove unused variables. Attempt to
10643 continue generating grant file in presence of error (Wilfried's
10644 patch to lang_finish).
10645 * ch-expr.c: Change assign_stack_temp calls so temps get recovered
10646 after each statement. Move convert call into
10647 chill_expand_assignment from ch-parse.y.
10648 * ch-grant.c: Generally re-order, clean up. Include Per's decode_mode
10649 simplification. Include commented-out hack in decode_mode to return
10650 type's name if type SEIZEd or already GRANTed in this file.
10651 * ch-lex.l: Add prototypes.
10652 * ch-parse.y (assignaction): Move convert call into
10653 chill_expand_assignment.

10666 * ch-parse.y (structured_variable): Return NULL_TREE is invalid WITH
10667 parameter is seen, don't count it in structured_variable_list. Pre-
10668 vents seg fault when only WITH operand is invalid.
10669 * ch-parse.y (label_spec): Correct assignment within IF expression which
10670 was intended to be equality test. Remove unused variables.
10671 * ch-tree.h: Add prototype. Remove unused EXCP_CODE enumeration, and
10672 prototyping editorial comments.
10673 * ch-typeck.c: Disable generation of code to validate array index for
10674 now. Should be done as a call-back from more generic array_ref code.
10675 Clean up parameter checking. Remove unused variables.
10677 Fri Mar 12 11:57:32 1993 Bill Cox (bill@rtl.cygnus.com)
10679 * ch-actions.c (chill_varying_type_p): Return FALSE if given NULL type.
10680 * ch-actions.c (build_chill_binary_op): Pass ALL arrays to
10681 build_char_array_expr.

10797 * expr.c (expand_expr): Use actual library name for __inpowerset
10799 * stor-layout.c (variable_size): Disable complaint about variable-

10808 actual library names. Change references to boolean_type_node
10809 to references to the TREE_CODE == BOOLEAN_TYPE, to follow the

10812 remove handling of CHAR arrays - they're handled in build_char_array_expr.

10814 need bitcount instead.
10815 build_chill_compound_expr, internal_build_compound_expr: Copy from C
10816 version that does stuff we don't want.
10817 build_binary_op: Check for in_size_in_bytes return < 0, indicating

10823 build_chill_length: Move VARYING array handling before regular char
10825 * ch-expr.c chill_expand_expr: Disable concatenate code - we need to
10826 the VARYING status of the target to do this correctly. Use powersetlen
10827 for the powerset operations, not a byte length.
10828 * ch-loop.c: Make CREATE_SCOPE #define to enable creation of a new scope
10829 for each CHILL loop, as Z.200 requires. Add powerset and error flags
10830 to loop structure. Evaluate user's powerset expression into a temp,
10831 scan it destructively with __ffsetclrpowerset or __flsetclrpowerset
10832 for powerset loop. Only do loop-end assignments if NOT a powerset
10833 loop, which has much less overhead now.

11051 * ch-lex.l (convert_bitstring), Changed SET_TYPE_CONSTRUCTOR to
11052 take a list of elements which are in the set. This corresponds

11055 New functions, to expand SET_TYPE CONSTRUCTORs.
11056 * varasm.c (output_constructor): Use pack_set_constructor
11057 to assemble a SET_TYPE constant from a CONSTRUCTOR.

11064 needed to export a static function.
11065 * ch-typeck.c (convert): Avoid needlessly (and lossingly) calling
11066 chill_expand_tuple to convert fix string to varying.
11067 * ch-actions.c (build_chill_binary_op): Promote short
11068 integer operands if needed (otherwise emit routines barf).

11071 * ch-parse.y (location): If IDENTIFIER is a CONST_DECL

11091 * ch-expr.c, ch-loop.c, ch-process.c, ch-tree.c, ch-typeck.c: change
11092 most integer_type_node references to chill_integer_type_node.

11097 * ch-parse.y: Add working exception handling support.
11098 * ch-lex.l, ch-parse.y: Prefer standard type terminology
11099 (BOOLS, CHARS) even though non-standard (BITS, CHAR) is ok.
11100 * ch-grant.c: Fix various problems related to granting
11101 types such as bitsets.
11102 * ch-tree.c (build_bitstring_type): Set TYPE_MIN_VALUE

11106 * ch-tree.h, ch-actions.c (lang_init), ch-grant.c (decode_mode):
11107 Undo kludge where integer_type_node was hardwired to 16 bits.
11108 Make integer_type_node etc have the same size as in cc1.
11109 New types chill_integer_type_node and chill_unsigned_type_node
11110 that correspond to the Chill source types INT and UINT.
11111 For now, these match the C 'short' types, but that should
11112 become a configuration option later,

11127 * ch-tree.h: remove prototypes added to c-tree.h.

11134 * ch-tree.def: add a new tree type - just for varying array
11135 references. We were using ARRAY_REF, but the underlying C
11136 code also generates that one.

11431 * chill.gperf, ch-hash.h: add Wilfried's tokens
11432 * ch-lex.l: fold in Wilfried's changes. Some tokens

11553 initializer name follows the standard 'collect' convention,

11558 * ch-parse.y: Move code that is common to the beginning of

11601 * ch-hash.h, chill.gperf: cleanup. fewer keywords seen by ch-parse.y.
11603 Sat Jan 2 13:27:49 1993 Per Bothner (bothner@rtl.cygnus.com)
11605 * ch-lex.l (check_newline): Use the orginal versions (derived
11606 from the C code, not the simplified, special-case version).
11607 Also, fix that version of check_newline to not call yylex()
11609 * ch-lex.l (yy_input): Call check_newline to handle
11610 newlines and check for # directives.
11611 * ch-lex.l (syntax): Don't recognize #-directives; these
11612 are now handled by check_newline.
11613 * ch-actions.c (lang_init): Call the modified version of
11614 check_newline(). Do this at the *after* we've initialized
11615 standard types, so this can be done while lineno is still 0.
11617 Sat Jan 2 10:57:20 1993 Bill Cox (bill@cygnus.com)
11619 * ch-hash.h, chill.gperf: add remaining reserved words.
11621 Sat Jan 2 09:59:55 1993 Bill Cox (bill@cygnus.com)
11623 * ch-tree.h, ch-parse.y, ch-lex.l: add remaining reserved words,
11624 names for exceptions
11626 Fri Jan 1 12:30:31 1993 Fred Fish (fnf@cygnus.com)
11628 * ch-tree.h (JOINER): Define joiner character the same way
11630 * ch-grant.c (chill_start_module_code): Use JOINER character
11631 to implement name mangling for the initializer function name.
11632 Algorithm is designed to be simple, distinct from C++ mangled
11633 symbols, and easy to convert to demangled form.
11635 Thu Dec 31 10:30:51 1992 Bill Cox (bill@rtl.cygnus.com)
11637 * ch-expr.c: make array assignments work with indirect refs.
11638 * ch-actions.c: prepare for array parameter handling.
11639 * ch-loop.c, ch-parse.y, ch-tree.def, ch-typeck.c: clean up.
11641 Thu Dec 31 15:29:20 1992 Per Bothner (bothner@rtl.cygnus.com)
11643 * ch-lex.l (yy_input): Re-write to return more than one
11644 character at a time (execpt when reading seize-files).
11645 Don't increment lineno until we start reading the next line.
11646 This fixes some off-by-one errors in lineno.
11648 Wed Dec 30 16:15:23 1992 Per Bothner (bothner@rtl.cygnus.com)
11650 * ch-convert.c: Assume use of new common.c.
11651 * ch-convert.c (convert_to_reference, convert_from_reference):
11652 New routines, to handle loc-identity declared variables and
11653 LOC parameters (both of which are implemented as references).
11654 * ch-lang.c (convert_to_boolean, convert_to_char): Move to
11655 ch-convert.c, where they would seem to belong.
11656 * ch-convert.c (convert): New function, since we no longer
11657 link in c-convert.c.
11658 * ch-expr.c (chill_expand_assignment): Handle by calling
11659 convert() instead of chill_comptypes().
11660 Also handle the LHS being a reference.
11661 * ch-parse.y: Add a procedure call as an action.
11662 * ch-parse.y (locdec, optlocinit): Move handling of
11663 loc-identity declarations from optlocinit to locdec
11664 - and add working semantics for it.
11665 * ch-parse.y (seizestatement, visibilty_stmt): Simplify.
11666 * ch-parse.y (grantstatement etc): Don't bother making list.
11667 * ch-lex.l: #include <sys/types.h> before <sys/stat.h>.

11671 * ch-parse.y, ch-expr.c: add support for declaring & assigning
11673 * ch-typeck.c: allow VARYING structures in assign_type_to_expr.
11675 Tue Dec 29 15:28:48 1992 Bill Cox (bill@cygnus.com)
11677 * ch-actions.c: implement expressions of arrays of char,
11678 ( concatenation, relationals ), correct type of code parameters
11679 * ch-expr.c: correct type of code parameters
11681 Tue Dec 29 11:16:19 1992 Bill Cox (bill@cygnus.com)
11683 * ch-decl.c: cleanup.
11684 * ch-parse.y: put emit_line_note() calls in lotsa places,
11685 per Fred's request; be sure that statements get counted also.
11686 * ch-lex.l: standardize function headers.
11688 Tue Dec 29 10:41:56 1992 Fred Fish (fnf@cygnus.com)
11690 * ch-decl.c (start_chill_function): Always return 1, rather
11691 than a random value.
11692 * ch-lex.l (check_newline): Add a version for chill that
11693 just snarfs the right value for main_input_filename out of
11694 the first line of the input file, without disturbing the
11695 lexer state or requiring it's assistance.
11696 * ch-actions.c (lang_init): Call check_newline, like the
11697 other language frontends, to get main_input_filename set
11698 from first line of input file.
11700 Mon Dec 28 18:49:01 1992 Bill Cox (bill@cygnus.com)
11702 * ch-parse.y: clean up conflicts. The remaining one is

11708 clean up some parser conflicts.
11710 Mon Dec 28 15:00:20 1992 Bill Cox (bill@cygnus.com)
11712 * ch-parse.y, ch-lex.l: add keywords and parsing for most of
11715 Sat Dec 26 20:48:23 1992 Fred Fish (fnf@cygnus.com)
11717 * chillrt/chillrt0.c: Oops, SVR4 doesn't need leading '_'
11718 on build_exceptions.
11720 Sat Dec 26 11:00:36 1992 Fred Fish (fnf@cygnus.com)
11722 * ch-grant.c (chill_finish_module_code): Call
11723 assemble_constructor_alias rather than assemble_constructor.
11724 * varasm.c (assemble_constructor_alias): New function,
11725 like assemble_constructor, but also handles the case where
11726 ASM_OUTPUT_CONSTRUCTOR is not defined and GNU ld is not
11727 being used. Emits a symbol table alias name with the correct
11728 prefix for collect to find and add to the __CTOR_LIST__.
11729 * chillrt/chillrt0.c: Build on previous hack that gets
11730 _build_exceptions into the __CTOR_LIST__, to make it work
11731 for both the non GNU-ld case and for the SVR4 case.
11733 Tue Dec 22 18:24:55 1992 Bill Cox (bill@cygnus.com)
11735 * ch-loop.c: clean up location enumeration - one more

11749 ch-loop.c: rough draft of location enumeration
11750 ch-lex.l, ch-expr.c, ch-decl.c: minor cleanup
11751 ch-actions.c: finish making pred() and succ() work.
11753 Mon Dec 21 10:04:35 1992 Bill Cox (bill@cygnus.com)
11755 * ch-actions.c: allow pred(char) and succ(char).
11757 Sun Dec 20 16:04:28 1992 Bill Cox (bill@cygnus.com)
11759 * ch-expr.c, ch-actions.c, ch-parse.y, ch-loop.c,
11760 c-expr.c: make DO WITH work.
11762 Sun Dec 20 12:22:53 1992 Bill Cox (bill@cygnus.com)
11764 * ch-loop.c, ch-actions.c, ch-typeck.c: powerset loops
11767 Sat Dec 19 14:20:23 1992 Per Bothner (bothner@cygnus.com)
11769 * c-typeck.c (process_init_constructor): Add warning if
11770 there is a duplicate default initializer element.
11771 * ch-typeck.c (chill_give_type_to_expr): New function,
11772 to handle coercion of an expression to context-given type,
11773 Takes care of untyped tuples, and case expressions.
11774 * ch-decl.c (do_decls), ch-typeck.c (chill_expand_return,
11775 chill_expand_result), ch-parse.y <assignaction>:
11776 Use chill_give_type_to_expr().
11777 * ch-typeck.c (chill_handle_case_label): New parameter list,
11778 to handle the (new) conventions for <case_label>, including
11779 default elements and ranges.
11780 * ch-parse.y <expanded_case_label>, ch-typeck.c
11781 (expand_case_expr): Use new version of chill_handle_case_label.
11782 * ch-decl.c (push_syndecls): Change parameters: Instead of
11783 TREE_LIST representing a compete <synonym definition statement>,
11784 just pass the parts of a single <synonym definition> as 3
11785 different parameters. Also, use chill_give_type_to_expr(),
11786 to handle untyped tuples in the RHS.
11787 * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct
11788 a tree - just call push_syndecls() on each <synonum_definition>
11790 * ch-parse.y (exprlist_get_single): Remove; no longer needed.
11791 * ch-parse.y: Handle <tuple> without mode name diferently from
11792 <tuple> with mode name. The latter is a <primval> that can be
11793 in most contexts, but if the <mode name> is missing, the <tuple>
11794 is only allowed in certain contexts. Use the new non-terminal
11795 <untyped_expr> to indicate those contexts where untyped tuples
11796 (and case expressions) are valid because the expression gets a
11797 type from its context (such as the RHS of an assignment).
11798 Use chill_give_type_to_expr in those contexts.
11800 Sat Dec 19 14:01:26 1992 Bill Cox (bill@cygnus.com)
11802 * ch-actions.c, ch-loop.c, Makefile.in: looping stuff.
11804 Sat Dec 19 10:16:20 1992 Bill Cox (bill@cygnus.com)
11806 * ch-parse.y: clean up warning messages from byacc. bison
11807 still complains thrice.

11811 * ch-actions.c (maybe_chill_comptypes): Delete unused
11813 (chill_comptypes): Add new parameter ERRSTR. All callers
11815 (build_chill_binary_op): Fix indentation to match GNU coding
11818 Fri Dec 18 08:18:13 1992 Bill Cox (bill@rtl.cygnus.com)
11820 * ch-parse.y, ch-expr.c, ch-actions.c, expr.c: major

11830 a default initializer element.
11831 * ch-parse.y: Implement default elements for tuples
11832 (as in '(else):' and '(*):' ).
11834 * ch-parse.y: Previous change to dis-ambiguate case-labels
11835 seems to have allowed getting rid of all of the expr_or_list hair.
11836 * ch-decl.c (do_decls): Undo Tiemann's change to "Handle
11837 initialization of multiple variables by a tuple" - the
11840 Wed Dec 16 11:17:53 1992 Bill Cox (bill@cygnus.com)
11842 * ch-parse.y: complete re-write of DO statement handling.
11843 now operational, except WITH is stubbed out. Improved
11844 syntax error message.
11845 * ch-actions.c: DO support: high_domain_value(), low_domain_value ().
11846 * ch-expr.c: fixes to IN_EXPR handling.
11848 Tue Dec 15 17:15:13 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11850 * ch-grant.c: Add casts to alloca return to avoid compiler warning.
11851 * ch-lex.c: Likewise.
11853 * Makefile.in (ch-lex.c): Delete incorrect free declaration added
11854 by flex to avoid compiler error.
11856 Tue Dec 15 08:41:08 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11858 * ch-decl.c (do_decls): Handle initialization of multiple
11859 variables by a tuple.
11861 * ch-decl.c (do_decls,start_chill_function): Make DECL public
11862 if we're doing a GRANT ALL at top level.
11864 * ch-lang.c (build_range_type): Deal with typecast to CHAR in
11867 * c-typeck.c (digest_init): SET_TYPE is not a scalar type.
11868 BOOLEAN_TYPE and CHAR_TYPE are scalar types.
11870 Mon Dec 14 14:58:32 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11872 * ch-lex.l (get_chill_{linenumber,filename}): New functions.
11873 (convert_number): Use LONG_TYPE_NODE instead of INTEGER_TYPE_NODE.
11875 Mon Dec 14 13:36:44 1992 Bill Cox (bill@cygnus.com)
11877 * expr.c: install and test newer Pascal IN_EXPR code,
11878 but don't activate it - it's very verbose.
11880 Mon Dec 14 00:22:49 1992 Fred Fish (fnf@cygnus.com)
11882 * Makefile.in (LANGUAGES): Add chill.

11898 Sun Dec 13 14:07:32 1992 Bill Cox (bill@cygnus.com)
11900 * ch-actions.c: fix unary operations, modulus ops,
11901 (discovered after extending regression tests).
11903 Sun Dec 13 12:16:32 1992 Bill Cox (bill@cygnus.com)
11905 * resync with Michael and Wilfried
11907 Sun Dec 13 09:11:25 1992 Michael Tiemann (tiemann@rtl.cygnus.com)

11911 * ch-tree.h: Add declarations for new chill functions that
11912 have been implemented but not (yet) declared.
11914 Sat Dec 12 00:17:23 1992 Per Bothner (bothner@cygnus.com)
11916 * c-typeck.c (process_init_constructor): Warn about duplicate
11917 labels for labelled initializer elements.
11918 * ch-lex.l (various operator tokens, such as "+"): Don't
11919 set yylval.code to a TREE_CODE; this is better done in parser.
11920 * ch-parse.y: Some work with case labels and tuples.
11921 Get literal range as tuple (and case) labels working.
11922 Fix some problems introduced by recent grammar overhaul.

11926 * ch-actions.c, ch-parse.y ch-tree.h ch-expr.c, ch-typeck.c:
11927 got long, real expressions working. We can also call a func-
11928 tion and use its return value.

11932 * ch-parse.y: Major change to remove or at least identify
11933 parser ambiguities. One result: We now allow actions that
11934 start with '(', as required by teh Blue Book. This does break
11935 some things; look for FIXME for things that need work.
11936 * ch-typeck.c (chill_expand_case_expr): We need an extra
11937 level of looping to (in the future) support <case label
11938 specification>s with more than one <case label list>.

11962 on arrays of BOOLs.
11964 Mon Dec 7 08:55:20 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11966 * ch-actions.c (lang_init): Set LINENO to 1 at beginning to
11967 indicate we are done with initialization.
11969 * ch-decl.c (do_decls): Set TREE_PUBLIC if we are doing a
11971 (start_chill_function): Ditto.
11973 * ch-lex.c (convert_bitstring): Set TREE_CONSTANT.
11974 (compiler_directive): Don't confuse compiler directives with
11975 equality comparison operators.
11977 * ch-parse.y: Clear CURRENT_LOCNAMELIST after calling do_decls.

11990 * tree.def: Move CARD_EXPR and SET_LE_EXPR back down with the other
11991 Pascal-required ones, since C++ no longer needs them. When
11992 Chill's public, a comment can be added to the effect that
11993 SET_LE_EXPR is also used by Chill.
11995 Fri Dec 4 12:05:01 1992 Bill Cox (bill@cygnus.com)
11997 * Restore CARD_EXPR and SET_LE_EXPR to tree.def.

12040 (decode_decl): Call `decode_constant' for CONST_DECLs.
12042 * ch-lex.l (char action): Use ridpointers instead of
12043 lookup_name to get "char"'s declaration.
12045 * ch-parse.y: Call `build_lang_decl' instead of `build_decl'
12046 when we need to build a TYPE_DECL.
12048 Tue Dec 2 09:44:05 1992 Bill Cox (bill@cygnus.com)
12050 * ch-typeck.c: clean up a gcc warning with a forward
12051 declaration of build_string_type.

12056 that are duplicated in c-decl.c
12058 Tue Dec 1 16:38:51 1992 Fred Fish (fnf@cygnus.com)
12060 * ch-actions.c (lang_init): Ifdef out initializations for
12061 __builtin_abs and __builtin_fabs, since they are duplicates of
12062 initializations in c-decl.c, and trigger spurious warnings.
12064 Tue Dec 1 16:35:18 1992 Bill Cox (bill@cygnus.com)
12066 * ch-parse.y: make size() work with a typename argument.

12093 Mon Nov 30 17:35:33 1992 Fred Fish (fnf@cygnus.com)
12095 * chillsh: New script frontend (ala g++), installed as "chill".
12096 Can't be called "chill.sh" because make tries to cat it into the
12097 "chill" directory. Can't be called just "chill" cause that's
12098 already there as a directory.
12099 * Makefile.in: Add rules to install chillsh as "chill".
12100 * chill/libchill.c: Temporarily ifdef out stuff that wants
12101 to conflict with i486/SVR4 runtime or wants to pull in librmt.a,
12102 which itself causes linkage to fail.
12104 Mon Nov 30 16:28:19 1992 Bill Cox (bill@cygnus.com)
12106 * ch-lex.l: added keywords for TRUNC, ROUND, FLOAT, LFLOAT
12107 conversion routines.

12109 Added production for SIZE(expr).
12110 * ch-actions.c: Add semantic routine chill_sizeof ().

12114 * ch-lex.l, ch-parse.y: Translate token PFEIL into English ARROW.
12115 * ch-parse.y (op6): Remove handling of string repetition operator,
12116 until we can figure out a way to parse it correctly.
12117 * ch-parse.y (optmodename): New non-terminal.
12118 * ch-parse.y (tuple): Merge the two variants using optmodename.
12119 * ch-parse.y (location): Add semantic actions for
12120 dereferencing operator ->.
12122 Mon Nov 30 08:01:29 1992 Bill Cox (bill@cygnus.com)
12124 * ch-actions.c: removed compile warning, better code for abs.
12126 * ch-parse.y: add productions for builtin functions succ, pred,
12127 abs, and size. Add %tokens also. Sort %tokens alphabetically.
12129 * ch-lex.l: add parsing for builtin function names, such as abs,
12130 pred, succ, etc. Put flex -a option into Makefile.in, so we can
12131 clean up the lexer soon.
12133 Tue Nov 24 14:18:48 1992 Per Bothner (bothner@rtl.cygnus.com)
12135 * ch-typeck.c (chill_handle_case_label, chill_handle_case_default):
12136 New functions, for code common to CASE actions and expressions.
12137 * chill.y: Replace some code by calls to chill_handle_case_label
12138 and chill_handle_case_default.
12139 * ch-typeck.c (chill_expand_case_expr): Add semantics.
12141 * tree.c: Change doing_chill_thang from extern to common.
12143 Mon Nov 23 18:34:22 1992 Per Bothner (bothner@rtl.cygnus.com)
12145 * ch-tree.def: New CASE_EXPR type, for case expressions.
12146 * ch-expr.c (chill_expand_expr): Hook for CASE_EXPR.
12147 * ch-typeck.c (chill_expand_case_expr): New function.
12148 Placeholder to implement case expressions.
12149 * ch-typeck.c (chill_expand_result, chill_expand_return):
12150 Handle mode-unspecified tuples and case expressions in
12151 the context of RETURN and RESULT actions.
12152 * chill.y (assignaction): Handle case expressions in the
12153 context of the RHS of an assignment action.
12154 * chill.y (caseaction): Remove spurious duplicate OF in grammar.
12155 * chill.y: Handle labeled structure tuples.
12156 * chill.y: New rules to parse CASE expressions.
12157 * tree.c (build_function_types): Allow Chill functions
12158 to return arrays and functions.
12160 Wed Nov 18 13:50:28 1992 Per Bothner (bothner@rtl.cygnus.com)
12162 * ch-typeck.c (chill_expand_tuple): New function. Expand a
12163 tuple (constructor) given an expected (context) type.
12164 * chill.y: Implement 'LHS := TUPLE' using expand_chill_tuple,
12165 using the mode of the LHS and the expected type of the TUPLE.
12166 * chill.y: Implement initialization.
12167 * chill.y: Fix some syntax bugs (forbidlist must be surrounded
12168 by parentheses), and remove or note ambiguities.
12169 * chill.y: Started converting layout style to be like c-parse.in.
12170 * chill.y: Implement IF expressions.
12171 * chill.y: Added syntax rules for tuples. Labelled and unlabelled
12172 array tuples should now work (in some contexts).
12173 * ch-actions.c: Initialize doing_chill_thang to 1.
12174 * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
12175 initializer, to make pushdecl and finish_decl work.
12176 * c-decl.c (convert_for_assignment): If Chill, don't convert
12177 function and arrays into pointers. (Maybe functions should
12178 still be converted?)
12179 * c-typeck.c (grokdeclarator): Allow functions in Chill
12180 to return arrays and functions.
12182 Mon Nov 16 15:40:47 1992 Per Bothner (bothner@rtl.cygnus.com)

12192 flags on assignment to result.
12193 * ch-typeck.c (build_chill_array_ref): Subtract lower
12194 bound of domain if non-zero. Preliminary hook for range checking.
12195 * ch-tree.h, chill.l: Combine variables range_check and
12196 range_check_disabled into global variable range_checking.
12197 * ch-tree.h: Better definitions of CH_CLASS_IS_VALUE
12198 CH_CLASS_IS_DERIVED.
