3440 in case of PROCESSes.
3442 * parse.c (parse_process_definition): Add call to
3443 build_process_wrapper.
3444 * parse.c (end_function): Remove the poplevel() call.
3445 build_process_header no longer makes the corresponding
3448 * grant.c (print_proc_tail): Remove special processing
3449 of PROCESSes, they look now like normal functions.
3451 * decl.c (init_decl_processing): Add declaration of memcmp
3454 * ch-tree.h: Add new prototype for build_process_wrapper,
3455 change prototypes for add_taskstuff_to_list and
3456 build_process_header.

3462 GNUCHILL_VERSION to ch/Makefile.
3463 * Make-lang.in (CHILL.mostlyclean): Add ch/ch-version.c.
3465 * Makefile.in (CHILL_OBJS): Add ch-version.o. ch-version.c
3466 will get generated every time a new Makefile will get
3468 * Makefile.in (GNUCHILL_VERSION): Remove it, its defined in
3471 * chill.in: In case of -fgrant-only pass "-S -o /dev/null"
3472 to the compiler to avoid generation of an object file.
3474 Thu Sep 8 12:07:28 1994 Per Bothner (bothner@kalessin.cygnus.com)
3476 * convert.c (display_int_cst), ch-tree.h: New function.
3477 * convert.c (digest_array_tuple): Use digest_int_cst to
3478 provide better error messages. Return error_mark_node on error.
3479 * grant.c (decode_const): Simplify by using digest_int_cst.
3480 * grant.c (format_character, find_assoc): Removed.
3482 * decl.c (do_decl): Add missing TREE_CHAIN.
3484 * decl.c (finish_incomplete_decl): Removed.
3485 (init_decl_processing): Don't set incomplete_decl_finalize_hook.
3486 (finish_decl): Remove old C-specific code to deduce size of
3487 array from initialization.
3488 (complete_array_type): Just make it abort.
3490 * except.c (finish_handler_array): Avoid calling C-specific kludge
3491 complete_array_type.
3493 * convert.c (digest_constructor): Rename, and re-write to:
3494 (digest_array_tuple, convert): No longer use the code in
3495 ../c-typeck.c; use a Chill-only implementation (sigh).
3497 * typeck.c (chill_expand_tuple): Remove unneeded call to
3498 complete_array_type.
3500 * expr.c (fold_set_expr), grant.c (decode_constant),
3501 typeck.c (expand_constant_to_buffer): Update name of called
3502 function unpack_set_constructor to get_set_constructor_bits.
3503 * expr.c (powersetlen ): Remove redundant call to convert.
3505 * ch-tree.h (unpack_set_constructor): Removed obsolete declaration.
3507 * inout.c (build_chill_writetext): Handle 64-bit integer literals
3508 by trying to convert them to a smaller type.
3510 * lex.l (convert_number): Always use long long type (possibly
3511 unsigned) to avoid problems with constant folding truncation.
3513 Mon Sep 5 08:08:22 1994 Wilfried Moser (moser@rtl.cygnus.com)
3515 * ch-tree.h (enum chill_built_in_function): Add BUILT_IN_QUEUE_LENGTH.
3516 Add new prototype (see tasking.c).
3518 * expr.c (build_generalized_call): Add processing of
3519 BUILT_IN_QUEUE_LENGTH.
3521 * tasking.c (build_queue_length): New function.
3523 * tasking.c (tasking_init): Add new external function definition.
3525 Thu Sep 1 15:38:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3527 * lex.l (default_lex): New function. Progress towards
3528 getting rid of [f]lex.
3530 * lex.l (convert_number): Use mul_double and add_double.
3531 Set result type to a reasonable type in which the literal
3532 will fit. Give error message if literal is too big.
3534 * lex.l (equal_number): Switch (temporarily) to permanent obstack.
3536 * typeck.c (build_chill_slice_with_range): Check for empty
3537 slice *after* we have checked for upper/lower limit in range.
3539 * grant.c (decode_mode): Remove unused code. (BOOL and
3540 CHAR ranges are represented as INTEGER_TYPEs.)
3542 * tasking.c (build_process_header): Add missing call to
3543 expand_start_bindings.
3544 * parse.c (end_function): Add missing expand_end_bindings.
3546 Wed Aug 31 17:25:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3548 * decl.c (init_decl_processing): Set set_alignment.
3550 Tue Aug 30 16:40:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
3552 * actions.c (print_missing_cases, check_missing_cases,
3553 BITARRAY_TEST, BITARRAY_SET): New functions and macros,
3554 to check for completeness of case actions and expressions.
3555 * decl.c (c_decode_option, init_decl_processing):
3556 Don't set warn_switch.
3557 * expr.c (chill_expand_case_expr): Call check_missing_cases
3558 instead of check_for_full_enumeration_handling.
3559 * parse.c (parse_case_actions): Call check_missing_cases.
3561 * expr.c (build_chill_binary_op): Remove some dead code.
3562 * expr.c (chill_truthvalue_conversion): Call build_chill_binary_op
3563 instead of build_binary_op.
3564 * ch-tree.h (binary_op_error, build_binary_op): Unused. Removed.
3566 * parse.c (end_function): Use kept_level_p in parameter to
3567 poplevel. This reverts a June 13 change.
3569 Fri Aug 26 11:50:19 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3571 * configure: Ignore --without, as ../configure does.
3573 Wed Aug 24 01:17:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3575 * lex.l: Change rule for decimal numbers to allow identifiers
3576 to start with an underscore (_).
3578 Fri Aug 19 16:38:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
3580 * tasking.c (build_receive_signal_case_label): Remove backwards
3581 chill_convert_for_assignment (which converted whatever garbage
3582 was in the *target* to the type of the signal argument!).
3584 Fri Aug 19 07:10:43 1994 Wilfried Moser (moser@rtl.cygnus.com)
3586 * inout.c (build_chill_io_list_type, build_enum_tables),
3587 tasking.c (build_tasking_struct): Temporarily reset
3588 maximum_field_alignment to 0, so that the compiler-built
3589 data structures needed by the RTS can be independent of -fpack.
3591 Thu Aug 18 13:39:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3593 * typeck.c (build_init_struct): Temporarily reset
3594 maximum_field_alignment to 0, so that the compiler-built
3595 data structures needed by the RTS can be independent of -fpack.
3597 Wed Aug 17 23:48:33 1994 Wilfried Moser (moser@rtl.cygnus.com)
3599 * parse.c (parse_primval, expect, parse_on_exception_list):
3600 Print error message only in pass 2.
3602 Wed Aug 17 13:47:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3604 * decl.c (switch_to_pass_2): Revert June 13 change,
3605 (Don't exit after pass 1 if an error was found.)
3607 * ch-tree.def (SLICE_EXPR): New tree-code.
3608 * typeck.c (build_chill_slice): For building a slice of a
3609 bit-string, just generate a SLICE_EXPR.
3610 * decl.c (init_decl_processing): Declare __pscpy.
3611 * actions.c (chill_expand_assignment): Handle a SLICE_EXPR
3612 on the LHS of assignment, by calling __pscpy.
3613 * expr.c (chill_expand_expr): Handle SLICE_EXPR (as a RHS
3614 value) by using __psslice to copy slice to a temp.
3616 Wed Aug 17 05:52:44 1994 Wilfried Moser (moser@rtl.cygnus.com)
3618 * Make-lang.in: Change version of GNUCHILL compiler to 1.4.1.
3619 * expr.c (build_chill_length): Enable LENGTH built-in to process
3620 Buffers and Events too (Z.200/1992).
3621 * lex.l (yywrap): Always set yyin to finput and/or grt_in. On
3622 a linux system the previous version was not able to run.
3623 * tasking.c: Correct processing of infinite buffer- and event-length
3624 to avoid RANGEFAIL warning.
3626 Thu Aug 11 11:46:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3628 * parse.c (parse_if_expression_body): Don't call the C-specific
3629 build_conditional_expr. Just do build_nt (COND_EXPR, ...).
3630 * convert.c (convert): Convert a COND_EXPR by converting
3633 * convert.c (convert): Don't call convert before
3634 convert_to_reference. It's apt to do weird and unneedful things.
3635 * convert.c (convert): If the expression is varying, just call
3636 varying_to_slice, which simplifies quite a bit.
3638 * ch-tree.h (varying_to_slice): Add prototype.
3639 * typeck.c (varying_to_slice): Remove prototype.
3641 * satisfy.c (satisfy): Move case PAREN_EXPR from type 'e'
3644 * except.c (emit_setup_handler): Temporarily reset the
3645 maximum_field_alignment to zero so the compiler's exception
3646 data structures can be compatible with the run-time system,
3647 even when we're compiling with -fpack.
3649 * expr.c (compare_records): Call saved_if_needed on operands.
3651 * expr.c (build_set_expr case NE_EXPR): Don't use __nepowerset
3652 which has been reimplemented to just call __eqpowerset and
3653 invert the result. Inline this new implementation by
3654 handling as EQ_EXPR, and inverting the result.
3655 * decl.c (init_decl_processing): Don't define unused __eqpowerset.
3657 * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
3658 type boolean_type_node, not void_type_node. (Fixing this
3659 avoids a crash in the back-end.)
3661 * grant.c (decode_constant): In a CALL_EXPR, if the argument
3662 list is not a TREE_LIST (as in string repetiation), don't
3665 Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3667 * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
3668 CONST_DECL is from a SET definition. (This is safer than
3669 checking that the type is ENUMERAL_TYPE, because synonym
3670 definitions may have a NULL TREE_TYPE.)
3671 Also, if we have duplicate enums whose types are identical,
3673 * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
3674 an extra 'quiet' parameter, which is true if we're called from
3675 bind_sub_modules. (In that case an error message about duplicated
3676 decls would be repeated later, so suppress it.)
3678 * parse.c (stmt_count): Removed, not used.
3679 (INIT_ACTION): Call emit_line_note only if !ignoring.
3680 (parse_begin_end_block): Do INIT_ACTION even if ignoring.
3682 Fri Aug 5 12:39:11 1994 Per Bothner (bothner@kalessin.cygnus.com)
3684 * parse.c (parse_untyped_expr): Add missing semi-colon.
3686 Thu Aug 4 17:40:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
3688 * parse.c (parse_untyped_expr): Fix various problem for the
3689 case that we see a '(': Add missing 'case' keyword.
3690 Only recurse if '(' is followed by 'if', 'case' or '[',
3691 and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
3693 * parse.c (parse_send_action): Remove extra nreverse.
3695 Thu Jul 28 04:00:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3697 * expr.c (build_allocate_global_memory_call, build_allocate_memory_call):
3700 Tue Jul 26 22:48:15 1994 Michael Tiemann (tiemann@blues.cygnus.com)
3702 * parse.c (parse_untyped_expr): Added missing "case" before LPRN.
3703 Added a missing call to `require' as well.
3705 Tue Jul 19 10:30:12 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3707 * lex.l (yywrap): Define as yywrap_chill to avoid conflicts with
3708 the extern declaration in the flex skeleton.
3710 Mon Jul 18 23:06:04 1994 Per Bothner (bothner@kalessin.cygnus.com)
3712 * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
3713 Check the type of the instance expr using CH_COMPATIBLE,
3714 and not just == instance_type_node. (This allows
3715 the expression to have mode READ INSTANCE).
3716 * tasking.c (build_instance_type): Give instance_type_node
3717 a non-null novelty (i.e. different from a struct).
3718 * tasking.c (build_receive_case_start, build_delay_case_start):
3719 Check that for a location using CH_LOCATION_P.
3721 Mon Jul 18 13:22:23 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
3723 * expr.c (finish_chill_unary_op): Use TREE_SET_CODE not TREE_CODE
3724 to modify a tree code.
3726 Mon Jul 18 11:24:57 1994 Bill Cox (bill@rtl.cygnus.com)
3728 * convert.c (digest_structure_tuple): Fix thinko in TREE_CODE
3731 Mon Jul 18 05:40:15 1994 Doug Evans (dje@canuck.cygnus.com)
3733 * decl.c (warn_bad_function_cast): Define so cc1chill will link.
3735 Thu Jul 14 18:37:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3737 * parse.c (parse_send_action): Do tree_cons *before* checking
3740 Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3742 * convert.c (digest_structure_tuple): Don't use convert to
3743 coerce initial value, use chill_convert_for_assignment instead.
3744 (Thus we also get range_checking.)
3746 * expr.c (build_chill_card): Use force_addr_of instead of
3747 build_chill_addr_expr.
3749 * loop.c (build_temporary_variable): Stylistic tweak.
3750 * loop.c (maybe_make_for_temp): Initialize temp using
3751 explicitly, not using assignment. Avoids a problem if
3752 the expression is read-only.
3753 * typeck.c (smash_dummy_type): Always used the saved TYPE_NAME
3754 and CH_NOVELTY_FLAG.
3756 Wed Jul 6 20:12:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3758 * expr.c, ch-tree.h (finish_chill_unary_op): New function,
3759 based on code ripped out of build_chill_unary_op.
3760 (build_chill_unary_op): Call finish_chill_unary_op unless pass==1.
3761 * satisfy.c (satisfy): Call finish_chill_unary_op when needed.
3763 Mon Jun 27 11:29:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3765 * tree.c (save_if_needed), ch-tree.h: New function.
3766 * typeck.c (build_chill_slice_with_range,
3767 build_chill_slice_with_length): Call save_if_neeed on array arg.
3768 * expr.c (varying_to_slice): Re-write to use save_if_needed.
3770 * typeck.c (extract_constant_from_buffer): Handle BOOLEAN_TYPE.
3772 Mon Jun 27 01:11:10 1994 Wilfried Moser (moser@rtl.cygnus.com)
3774 * inout.c (build_chill_io_list_type): Change layout of __tmp_WIO_list
3775 that it is always the same, regardless if compiled with -fpack
3778 Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3780 * lex.l (yywrap): Kludge to work around mis-synchronization
3781 between lexer (which read ahead) and parser: Don't emit
3782 (left-over) uze_seizefile directives at the end of file.
3784 * typeck.c (build_chill_array_ref): Allow the derived
3785 array indexing syntax for arrays of bit strings.
3786 Add a comment explaining why.
3788 * typeck.c, ch-tree.h (string_assignment_condition): Change
3789 the interface. Return a boolean expression (which can be
3790 used in a conditional at run-time); never expand anything.
3792 * actions.c (chill_convert_for_assignment): Check
3793 string_assignment_condition here, rather than in callers.
3794 * actions.c (chill_expand_assignment): Don't need to check
3795 string_assignment_condition here.
3796 * expr.c (build_chill_function_call): Likewise.
3797 * satisfy.c (safe_satisfy_decl): Update accordingly.
3798 * decl.c (do_decl): Simplify testing and conversion by
3799 deferring everything to chill_convert_for_assignment.
3801 * parse.c: Combine the two variables 'ignore_exprs' and
3802 'ignore_actions' into one variable called 'ignoring'.
3803 * ch-tree.h: Add 'extern int ignoring'.
3804 * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
3805 Rename ignore_actions and ignore_exprs to ignoring.
3806 Remove unneeded extern declarations.
3807 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3808 build_chill_arrow_expr, build_generalized_call, build_delay_action,
3809 build_buffer_type, build_event_type): I changed my mind. It is
3810 cleaner to check for 'ignoring' in the parser, rather than here.
3811 * parse.c (parse_action, parse_primval, parse_opt_mode):
3812 Therefore we must check for ignoring here.
3813 * parse.c (parse_loc_declaration): Set ignoring in pass 2
3814 when parsing the mode.
3816 * tasking.c (generate_tasking_code_variable): Do arithmetic
3817 on signal_code etc using unsigned rather than signed shorts.
3819 * grant.c (static char* current_grant_modename): Removed.
3820 * grant.c (decode_decl case CONST_DECL): Remove error message.
3822 * Make-lang.in (CHILL_SRCS): Add $(srcdir)/ch/parse.c.
3823 * Makefile.in: Fix dependencies for parse.o.
3824 Remove some duplicate dependencies for $(TREE_H).
3826 Mon Jun 13 14:25:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3828 * typeck.c (build_chill_cast): Allow a value cast between
3829 non-discrete object of the same size, but with a pedwarn.
3830 * typeck.c (bit_string_assignment_condition,
3831 char_string_assignment_condition): Merge near-duplicate functions
3832 and place the code in string_assignment_condition.
3834 * decl.c (parm_flag, declare_parm_level, in_param_level_p):
3836 * decl.c (start_chill_function, finish_chill_function): Make
3837 parameter level have same nesting level as body, as required by Z200.
3838 * decl.c (switch_to_pass_2): Always exit if an error has been found.
3839 * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
3840 generated from GRANT ALL.
3841 * decl.c (lookup_name_for_seizing): Don't seize from
3842 the nesting level of builtins (predefined objects).
3843 * decl.c (lookup_name_for_seizing): Make more robust on error.
3845 * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
3846 be 'RESULT' (or 'result'). This makes it more accessible from gdb.
3847 Also, use do_decl to declare it, so that debugging symbols are
3848 generated. And, re-arrange so that actions that need to
3849 be done both passes (such as push_levels) use the same code.
3851 * parse.c (get_type_of): If ignore_exprs, don't lookup name.
3852 * parse.c (end_function): Fix poplevel params.
3853 * parse.c (expect): Don't read forwards on an error.
3854 * parse.c (parse_field): Don't define two tag_list locals!
3855 * parse.c (parse_pass_1_2): Better error message.
3857 * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
3858 parse_opt_mode, rather than vice versa. If parse_opt_mode
3859 returns NULL_EXPR, then parse_mode gives an error.
3860 Change parse_opt_mode (and any functions it calls) to only
3861 return NULL_TREE if there is no mode (even on ignore_exprs).
3862 (parse_set_mode, parse_structure_mode, parse_procedure_mode):
3863 Never return NULL_EXPR.
3864 * tasking.c (build_buffer_type, build_event_type): Return
3865 void_type_node instead of NULL_EXPR if ignore_exprs is true.
3867 * parse.c (parse_synonym_definition): Call parse_untyped_expr
3868 only if we have a mode.
3869 * parse.c (parse_send_action): Parse list of untyped_expr's,
3870 rather than a list of (typed) expressions.
3871 * parse.c (parse_primval): Emit error if '[' seen without
3872 preceding mode name. (If this is to be allowed, call
3873 parse_untyped_expr instead.)
3875 * parse.c (parse_array_index): Renamed to ...
3876 (parse_index_mode): ... to match Z200 terminology.
3877 Re-write to resolve some of the nastier ambiguities,
3878 and allow things like ' CHAR(10) : CHAR(20) '.
3880 * parse.c (parse_tuple_element): Change interface to return
3881 reversed list, so don't call nreverse.
3882 * parse.c (parse_tuple): No longer nreverse element list here.
3883 * parse.c (parse_opt_element_list): Do nreverse here instead.
3884 * parse.c (parse_case_label_list): Call nreverse at end.
3886 Fri Jun 10 15:36:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
3888 * typeck.c (chill_similar): Remove bogus "else".
3890 Wed Jun 8 00:01:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
3892 * ch-tree.h (TYPE_ARRAY_MAX_SIZE): New macro (and comment)
3893 to make it clearer that we are using TYPE_MAX_VALUE in a special way.
3894 * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
3895 * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
3896 * convert.c (convert): When converting a fixed string/array
3897 to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
3898 of (the type of) the padding.
3899 * convert.c (convert): If the concatenation is non-constant, use
3900 the low-level 'build' to set the type of the result (which is usually
3901 a fixed-size array) rather than depend on build_chill_binary_op
3902 to figure it out (it's unable to simplify the size to a constant).
3904 Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
3906 * lang.c (lang_decode_option): Let -fspecial_UC imply
3907 -fno-ignore-case without requiring it explicitly.
3908 * lang.c (lang_decode_option): Support (experimentally)
3909 the -fpack and -fno-pack flags.

3913 * configure: Add support for --program-prefix and --program-suffix.
3915 Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3917 * convert.c (digest_constructor): Check that initial value
3918 is compatible with element mode before calling convert.
3919 * typeck.c (chill_compatible): A string mode is not compatible
3920 with an untyped constructor.
3921 * decl.c (do_decl): Clean up error messages. Use error_with_decl.
3923 * ch-tree.h: Fix inconsistencies: bool_true_node ->
3924 boolean_true_node, and bool_false_node -> boolean_false_node.
3925 * typeck.c (valid_array_index_): Minor simplification.
3927 Tue May 31 04:33:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3929 * inout.c (build_chill_writetext): Add correct processing
3930 of POWERSET RANGE (setmode).
3932 * lex.l (same_file): Add searching for file(s) in
3935 Fri May 27 14:22:42 1994 Per Bothner (bothner@kalessin.cygnus.com)
3937 * Make-lang.c (CHILL.mostlyclean, CHILL.distdir): Don't list
3938 yacc/bison output files, since the grammer is no longer in yacc.
3939 * config-lang.in (diff_excludes): Likewise.
3941 Thu May 26 16:38:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3943 * gperf, hash.h, lex.l, parse.h: Rename PROCESS_TYPE token
3944 (in some files spelled PROCESS_TYPE_ to avoid clashes
3945 with the PROCESS_TYPE tree_code) to PROCESS_TYPE_TOKEN.
3947 Thu May 26 02:18:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3949 * timing.c (build_cycle_start): Change call to __define_timeout.
3950 * decl.c (init_decl_processing): Change definitions of
3951 __define_timeout and __wait_timeout.
3953 Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
3955 Replace yacc-based parser with a recursive-decent parser.
3956 (This may seem backwards, but Chill [like C++] is not a
3957 language that is remotely LALR(1). Using a R-D parser
3958 allows us to use look-ahead and to back-up to resolve the
3959 difficult ambiguities.)
3961 * parse.c, parse.h: New files, containing new r-d parser.
3962 * Makefile.in: Update accordingly.
3963 * actions.c (chill_convert_for_assignment): Don't return
3964 NULL_EXPR if ignore_exprs is true. It simplifies the parser
3965 if we consistently reserve NULL_EXPR for a missing expression.
3966 * expr.c (build_chill_function_call): Likewise.
3968 * lex.l: Tweaks for new parser.
3969 * lex.l (prepare_paren_colon, paren_paren_colon_level,
3970 paren_level): Ugly hack no longer needed.
3972 * expr.c (build_chill_function_call): Cleanup.
3973 Call chill_convert_for_assignment to convert IN/INOUT
3974 paramaters on both input and output. For LOC parameters,
3975 give error if actual is a non-referable location.
3976 * actions.c (convert_for_assignment): Add new parameter (a
3977 "place" string used in error messages).
3978 * actions.c (adjust_parm_or_field): Removed.
3979 * actions.c (chill_expand_assignment): Take just a single LHS,
3980 and move support for multiple assignments to ...
3981 (expand_assignment_action): ... here. Some cleaning up.
3982 * timing.c (build_cycle_start): Adjust accordingly.
3983 * actions.c (expand_assignment_to_varying_array): Likewise.
3984 * tasking.c (many places): Ditto.
3985 * ch-tree.h: Fix declarations appropriately.
3987 * parse.c (parse_defining_occurrence_list): Return a single
3988 IDENTIFIER_NODE (instead of a singleton list) in the common
3989 case. Minor complication to save a minor amount of space.
3990 * decl.c (do_based_decls): Move guts of code into ...
3991 (do_based_decl): ... this new function.
3992 * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
3993 * decl.c (push_syndecl): Replace by ...
3994 (push_syndecl): ... (which only supports a single name).
3995 (push_modedef): Only handle a single name.
3996 * tasking.c (build_process_header, build_signal_struct_type):
3999 * expr.c (build_generalized_call): Handle string repetition.
4000 * expr.c (build_chill_repetition_op): Change interface.
4001 * grant.c (decode_constant): Allow parameter list to be
4002 a non-TREE_LIST. (Used for string repetition.)
4004 Wed May 25 11:28:48 1994 Per Bothner (bothner@kalessin.cygnus.com)
4006 * lex.l (make_identifier): Replaced by ...
4007 (read_identifier, handle_name): ... new functions.
4008 * lex.l: Parse an identifiers using read_identifier using
4009 read_identifier and handle_name, rather than having [f]lex
4010 do it. (One reason is that lex uses a fixed-size buffer.)
4012 * lex.l (read_directive, skip_directive): New functions.
4013 Use them to parse compiler-directives, instead of rather
4014 ugly and useless use of lexer start conditions.
4016 Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4018 * decl.c (unnamed_module_number): Renamed to ...
4019 (module_number): .. and make non-static.
4020 (push_module): Always increment module_number.
4021 * lex.l (yywrap): Print warning if no modules seen.
4023 * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
4024 decl to current_seizefile_name (which is unreliable).
4025 * grant.c (chill_grant): Set it here instead.
4027 * expr.c (fold_set_expr): Use int_size_in_bytes instead of
4028 TYPE_PRECISION (which is not defined for a SET_TYPE).
4030 Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
4032 Cleanup to remove need for variables in common storage.
4033 * decl.c: Remove unused use of current_obstack.
4034 * actions.c (maybe_chill_check_decl): Remove unused function.
4035 * actions.h, lang.c: Remove uses of doing_chill_thang.
4036 * ch-tree.h (void_list_node): Make extern (rather than common).
4037 * decl.c (void_list_node): Add definition.
4039 Thu May 19 06:54:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
4041 * configure (build): Build canon_host and canon_target
4042 to pass it to all subsequently generated Makefiles (needed
4043 for testsuite/execute in case of cross build).
4045 Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4047 * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
4048 the input type, which loses with the no-longer-new 2-pass
4049 implementation, since the input "type" could be an IDENTIFIER_NODE.
4050 * grant.c (raw_decode_mode): Rename to decode_mode.
4052 Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
4054 * typeck.c (chill_location): Neither a STRING_CST nor a
4055 CONSTRUCTOR is a location.
4056 * typeck.c (chill_root_mode): Convert a function to a
4057 pointer-to-function.
4058 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
4059 build_chill_arrow_expr): If ignore_exprs, return operand
4060 rather than NULL_EXPR. This makes it easier for the parser to
4061 distinguish missing expressions.
4062 * expr.c (build_max_min): Convert the lower bound of a
4063 set to a long before calling run-time routine.
4064 * expr.c (build_chill_pred_or_succ): Use discrete_type_p
4065 to check the argument type.
4066 * expr.c (build_chill_arrow_expr): If argument is not a location,
4067 do a predwarn if it is a STRING_CST or has function type.
4069 Tue May 17 06:05:13 1994 Wilfried Moser (moser@rtl.cygnus.com)
4071 * configure (build): Remove building of canon_host and canon_target.
4072 It doesn't work in any case.
4074 Mon May 16 02:10:35 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).
4079 * Make-lang.in (chill-runtime): Change chill to CHILL in the case
4080 statement to build chill-runtime automatically.
4082 Mon May 9 15:30:08 1994 Doug Evans (dje@canuck.cygnus.com)
4084 * Makefile.in (FLAGS_TO_PASS): Define.
4086 (../cc1chill): Depend on $(OBJDEPS) $(C_OBJS).
4087 * Make-lang.in (cc1chill): Delete dependency on $(OBJS) $(BC_OBJS).
4088 (CHILL.mostlyclean): Use `mostlyclean' as recursive target.
4090 Sun May 8 13:05:00 1994 Per Bothner (bothner@cygnus.com)
4092 * Make-lang.in (cc1chill): Should not depend on libgcc.a.
4094 Thu May 5 18:58:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
4096 * decl.c (copy_lang_decl): New (dummy) function.
4098 Mon May 2 14:33:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
4100 * parse.y (sendaction): Fix thinko (in sense of condition).
4101 * tasking.c (build_receive_case_label): Another thinko.
4103 * parse.y (optsigdest): Force ignore_exprs to 0 while parsing
4106 * decl.c (build_chill_function_type): Don't call layout_type
4107 (since that may prevent parameter or result types being
4108 properly satisfied).
4109 * satisfy.c (satisfy): Layout FUNCTION_TYPEs.
4110 * parse.y (procmode): Call build_chill_pointer_type, rather
4111 than build_pointer_type (which incorrectly sets TYPE_SIZE).
4113 * parse.y (get_type_of): Handle TYPE_DECL (again).
4114 * parse.y (optresultspec): Call build_chill_reference_type, rather
4115 than build_reference_type (which incorrectly sets TYPE_SIZE).
4116 * parse.y (range_or_mode): Rename to plain range, since it
4117 no longer matches modename.
4118 * actions.c (chill_handle_case_label_range): New function, with
4119 functionality moved out of chill_handle_case_label.
4120 * actions.c (chill_handle_case_label): Handle here the case that
4121 the label_value is a TYPE_DECL (modename). Also clean up some.
4122 * typeck.c (build_chill_slice_with_length): Convert max_index
4123 to the type of min_value. (Old code broke on varying strings.)
4125 Sun May 1 13:53:36 1994 Doug Evans (dje@canuck.cygnus.com)
4127 * Makefile.in (BC_OBJS): Delete all references
4128 (OBJS): Cat ../stamp-objlist to get language independent files.
4129 (../cc1chill): Delete dependency on $(OBJS).
4130 * Make-lang.in (cc1chill): Depend on stamp-objlist.
4132 Sat Apr 30 14:50:15 1994 Per Bothner (bothner@kalessin.cygnus.com)
4134 * lex.h, lex.c: Remove lastiddecl.
4135 * lex.l (name_type_signal): Simplify. We no longer check for
4136 TYPENAME or SIGNALNAME (which was unreliable with two passes).
4137 Also rename to make_identifier.
4138 * parse.y: Cleaned up grammar to not need SIGNALNAME or TYPENAME.
4139 * Makefile.in (stamp-parse); One conflict fewer!
4140 * parse.y (rccase_label_flag): Moved to tasking.c.
4141 * parse.y (rccase_label): Move most of the logic to
4142 build_receive_case_label in tasking.c.
4143 * parse.y (sendaction): Re-write to not depend on SIGNALNAME.
4145 * parse.y (name): Do name lookup here (and not in location).
4146 * parse.y: Replace most uses of NAME by higher-level non-terminals:
4147 simple_name_string, name_string, defining_occurrence, or name.
4149 * tasking.c (build_receive_signal_case_label,
4150 build_receive_buffer_case_label): New functions, split out from
4151 build_receive_case_label.
4152 * tasking.c (build_receive_case_label): Change parameters
4153 and return type. Moved stuff here (from the parser).
4154 * tasking.c (struct rc_state_type): Removed had_errors.
4155 Return error_mark_node instead.
4156 * tasking.c (build_rccase_set_error), ch-tree.h: Removed.
4158 * expr.c (build_generalized_call): If func is a signal type,
4159 call build_signal_descriptor.
4161 * parse.y (arrayindex): Renamed to index_mode, to match Z.200.
4162 * parse.y (ioindexmode): Removed; use index_mode instead.
4163 * expr.c (build_generalized_call): If args is a RANGE_EXPR,
4164 we have either a slice or a range mode, depending on func.
4165 * parse.y (index_mode): If we got an 'expr', only allow a name,
4167 * parse.y (call): A slice with both end points can be a range
4168 mode, so defer handling to build_generalized_call (or index_mode).
4170 * typeck.c (build_chill_slice_with_length): Fix type-checking.
4171 * typeck.c (chill_novelty): Undo (part of) change of April 28:
4172 The novelty of a range mode is the novlety of the parent.
4173 * typeck.c (chill_root_mode): Don't return integer_type_node
4174 if argument has non-nil novelty.
4176 * decl.c (global_bindings_p): Return -1 as true, for the sake
4177 of variable_size (in ../stor-layout.c).
4179 Fri Apr 29 13:42:43 1994 Per Bothner (bothner@kalessin.cygnus.com)
4181 * parse.y: Remove TYPENAME and modename. These are now plain
4182 NAMEs. Modify parsing actions appropriately.
4183 * expr.c (build_generalized_call): Handle the case that
4184 TREE_CODE (func) == TYPE_DECL (as in a cast).
4185 * lex.l (name_type_signal): Never return TYPENAME.
4186 * parse.y (get_type_of): If pass 1, just return the argument.
4188 * decl.c (do_decl): If an initializer has the wrong type,
4189 replace it by NULL_TREE, to avoid subsequent errors.
4191 Thu Apr 28 15:21:56 1994 Wilfried Moser (moser@rtl.cygnus.com)

4235 * typeck.c (smash_dummy_type): Handle the special case of a
4236 NEWMODE of a range mode, as required by Z200, by creating a
4237 new parent mode with the new novelty (and casting the min
4238 and max of the range to teh new parent mode).
4239 * typeck.c (chill_novelty, chill_root_mode): Remove special
4240 kludges for of NEWMODE ranges.
4241 * expr.c (build_chill_lower_or_upper): New function, combining
4242 the "guts" of build_chill_lower and build_chill_upper.

4244 need to kludge the novelties.
4246 * typeck.c (valid_array_index_p): A string index expression
4247 need not be Compatible with the index type; only similar.
4249 * decl.c (layout_chill_variants): If error seen, skip stuff
4250 (rather than aborting or crashing).
4251 * decl (push_modedef): If newdecl's type is an error mark,
4252 continue rather than aborting.

4256 * Make-lang.in: Update of directory reorg from fsf.
4257 * config-lang.in: Ditto.

4261 * typeck.c (chill_similar): Check RECORD_TYPEs properly,
4262 * convert.c (convert): If all else fails, just call convert1.
4263 Thus we can now convert RECORD_TYPEs (assuming they are similar).
4265 * parse.y, lex.l: Remove BUFFERNAME (use location/expr instead).

4273 * parse.y (modename): No longer match SIGNALNAME. Instead, add it
4274 to name and simple_name_string. This removes a reduce/reduce conflict.
4275 * Makefile.in (stamp-parse): Expect fewer conlicts.
4277 * lex.l (yywrap): Move check for circularly seizeing current
4278 grant-file from here ...
4279 * lex.l (handle_use_seizefile_directive): ... to here.
4280 This is to avoid calling stat on a not-yet written grantfile,
4281 now that we're using same_file (which calls stat).
4282 * grant.c (set_use_this_gf): Removed.
4283 * grant.c (set_default_grant_file): Set grant_file_name here,
4284 because we need it earlier (due to above lexer change).
4286 * typeck.c (layout_chill_struct_type): Remove useless code to
4287 remove zero-width bitfield (which messes up CONST_DECLs).
4289 Sat Apr 23 13:16:39 1994 Bill Cox (bill@rtl.cygnus.com)
4291 * Makefile.in (check): Assure that 'ld' is available before checking.

4332 * Makefile.in (check): Simplified regression.sh call.
4333 * regression.sh: Change command-line parsing. Default
4334 srcdir to the script's path. Calculate objdir
4335 internally - don't pass it in.

4380 * actions.c (chill_expand_assignment): Check for compatibility
4381 _after_ "expanding out" a binary operation. This fixes
4382 the case "STRING //:= CHAR".
4384 * lex.l (equal_number): Convert symbol to integer_type_node, to
4385 force the value to be INT-derived (and avoid novelty conflicts).

4403 or assign to DECL_RESULT as appropriate.
4404 * decl.c, ch-tree.h (current_function_returns_value,

4438 a process argument has other attribute then IN or LOC.

4487 Clean up error message for OUT//INOUT not location to use only 1 line.
4488 Add error message for OUT/INOUT if type is READonly.
4489 * typeck.c (build_chill_modify_expr): Simplify.
4491 Sun Mar 27 19:30:25 1994 Bill Cox (bill@rtl.cygnus.com)
4493 * Makefile.in: Clean up generally. Assure that

4525 Wed Mar 23 13:34:18 1994 Bill Cox (bill@rtl.cygnus.com)
4527 * expr.c (build_generalized_call): Revert previous change.
4528 To do this correctly, we need a new parsing mechanism, and

4550 * configure: Generate better .gdbinit files.
4552 Tue Mar 22 11:59:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
4554 * actions.c (check_range): Don't emit dynamic checks
4555 if not current_function_decl.
4557 * parse.y (arrayindex): Allow expr (error is emitted
4558 at semantic level if not the NAME of a type).
4559 * typeck.c (build_chill_cast): Re-enable some casts.
4560 * satisfy.c (safe_satisfy_decl): Remove redundant CONST check.

4577 string assignment case.
4578 * expr.c (chill_expand_expr): Now that we're using build_chill_function_call,
4579 the actual parameters need to be converted to the unsigned long
4580 type explicitly. Do that.
4581 * satisfy.c (safe_satisfy_decl): Correct range-checking code.
4583 Mon Mar 21 16:25:07 1994 Bill Cox (bill@rtl.cygnus.com)

4593 * typeck.c (layout_chill_range_type): Instead of tree_int_cst_lt
4594 use compare_int_csts (which is more robust when signedness differs).

4598 * expr.c (chill_expand_expr): Code to expand SET_IN_EXPR,
4599 moved from expand_expr in ../expr.c. Also add some extra
4600 conversions (because we're now using build_chill_function-call).
4601 * actions.c, decl.c, expr.c, grant.c, parse.y, typeck.c:
4602 Use SET_IN_EXPR in place of IN_EXPR.
4604 * expr.c (build_compare_discrete_expr), ch-tree.h: New function,
4605 with code moved from build_compare_expr.
4606 * expr.c (build_compare_expr): Re-enable compatibility test.

4633 to be compatible with the N-value class, with suitable M and N.
4634 * typeck.c (build_chill_slice): Don't smash a void TREE_TYPE.

4637 * expr.c (build_compare_expr): Fix thinko. Add save_exprs.
4639 * expr.c (build_compare_expr): Fix a transcription bug
4640 (for converting NULL INSTANCEs). Also #include convert.h.

4643 Works even if their types have different TREE_UNSIGNED.
4644 * expr.c (finish_chill_binary_op): Moved code dealing with
4645 the comparison operators from here ...
4646 * expr.c (build_compare_expr): ... to new function here.

4671 to have consistent operand types.
4672 * typeck.c (valid_array_index_p): Change interface to pass
4673 validity conditions back on caller's TREE_LIST. We
4674 cannot link the conditions to anything which a
4675 layout_type routine will expand, since that will occur
4676 before the exception handler is set up.
4677 Change calls to valid_array_index_p also.
4679 Fri Mar 18 14:40:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
4681 * actions.c, except.c, loop.c, tasking.c: Call

4685 * loop.c (top_loop_end_check): Coerce library function arg.
4686 * convert.c, expr.c: Re-write to avoid calls to C-specific
4687 function build_unary_op (e.g. by calling build1 directly).
4689 * typeck.c (chill_equivalent): Change to force failure
4690 for non-matching integral types (even if not ranges).
4692 * typeck.c, ch-tree.h (build_chill_slice): Make non-static.
4693 * expr.c (varying_to_slice): Call build_chill_slice (and not
4694 build_chill_slice_with_length, which does bunches of range
4695 checking and does not allow the length to be zero).
4696 * convert.c (convert): Fix off-by-one error.
4697 * actions.c (chill_expand_array_assignment): Minor cleaning up.

4705 * typeck.c (build_chill_slice_with_length): Fix Bill's previous fix.

4716 * typeck.c (build_chill_slice), expr.c (chill_expand_expr
4717 [case CONCAT_EXPR]): Remove kludge setting slice size upper bound
4718 in TYPE_LANG_SPECIFIC, and restore kludge setting it in MAX_VALUE.
4719 * typeck.c (build_chill_slice): Use TYPE_MAX_VALUE of
4720 array_type if needed for size upper bound of slice_type.
4721 * expr.c (build_concat_expr): Improve calculation of size upper bound.
4723 * typeck.c (valid_array_index_p): Check compatibility using
4725 * typeck.c (build_chill_slice_with_length); For now revert
4726 calling valid_array_index_p on length. (It makes it harder
4727 to realize when the slice is constant length.)
4728 * expr.c (build_chill_indirect_expr): Minor tweak. (This
4729 seems to work around a weird C compiler bug. ??)
4731 * expr.c (build_chill_function_call): Cleanup so it doesn't
4732 call build_function_call (in c-typeck.c).
4733 * typeck.c, expr.c: Use build_chill_function_call instead of
4734 build_function_call (in c-typeck.c).
4736 * parse.y (discrete_mode): Move some of the rules from
4737 non_array_mode into new non-terminal.
4738 (arrayindex): Use discrete_mode (with NAME and TYPENAME) to

4741 * convert.c (digest_structure_tuple): Add missing parameter.
4742 * decl.c (comptypes): Remove unused prototype.
4743 * decl.c (build_chill_function_type): Handle NULL return_type
4744 correctly (convert to void_type_node).
4745 * decl.c (init_decl_processing): layout boolean_type_node *after*
4746 we've set it's TYPE_MIN_VALUE and TYPE_MAX_VALUE.
4748 Wed Mar 16 16:08:22 1994 Bill Cox (bill@rtl.cygnus.com)

4751 * convert.c (convert): Correct calculation of padding length.
4752 * decl.c (grok_chill_fixedfields): Move ignore_exprs test to
4753 parse.y where it belongs. This permits the removal of a kludge
4754 in make_process_struct.

4756 code to output error in only one pass.

4766 rather than validate_varying_array_ref.
4767 * ch-tree.h: Fix prototype for valid_array_index_p.
4768 * expr.c (chill_expand_expr): Call build_chill_array_ref to get
4770 (build_hill_lower, build_chill_upper): Return value now inherits
4771 the novelty of the input parameter.
4772 (varying_to_slice): Use CH_NOVELTY macro rather than calling
4773 chill_novelty directly.
4774 * grant.c (newstring): Make len unsigned and cast xmalloc parameter
4776 (print_integer_type): Pass string value as APPEND's second parameter.
4777 (decode_decl): Pass a boolean expression as print_proc_tail's
4779 (chill_finish_module_code): Make xmalloc's parameter unsigned.
4780 * lex.l: Pass sizes to xmalloc as unsigned ints. Pass second
4781 parameter to in_word_set as unsigned.
4782 * loop.c (build_loop_start): Check top_loop_end_check return value.
4783 * parse.y: Add casts to int for third do_decls parameter, fifth
4784 build_loop_iterator parameter, etc.
4785 * tasking.c (build_receive_case_end): Chack cond_stack before popping.
4786 * typeck.c (validate_varying_array_ref, chill_max_vary_array_index,
4787 valid_array_index): Delete them. They're now unused.
4788 (valid_array_index_p): Add function, call it everywhere that an
4789 array index is checked.
4790 (build_chill_slice): Restore old functionality where varying_to_slice
4791 is called to handle slices of varying arrays, rather than handling
4793 (build_chill_slice_with_range, build_chill_slice_with_length):
4794 Check range limits for TREE_CONST before calling tree_int_cst_lt.
4795 Delete now-obsolete checks of constant indices.
4797 Mon Mar 14 17:26:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4799 * parse.y (modeless_expr): New rule to allow ([...]) and (if...)
4800 to count as untyped_exprs. (This is not really permitted by the
4801 Blue Book, but has been requested by customers.)
4803 Thu Mar 10 10:11:02 1994 Bill Cox (bill@rtl.cygnus.com)
4805 * chill.texi: Document new command-line options.
4806 * expr.c (build_chill_num): Set unsigned parameter for

4818 * decl.c (finish_chill_function, finish_decl): Provide the
4819 new permanent_allocation flag.

5007 Wed Feb 23 15:07:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
5009 New cleaner solution to the following problem:
5010 Chill allows an action to be followed by an ON-handler.
5011 But we don't know if an action has a handler until we've parsed
5012 its end, yet we want to generate extra code to set up an
5013 exception handling contour only if needed. The old solution
5014 would generate code for the action into an rtl sequence, and then
5015 splice in the exception-setup code if we later found we needed it.
5016 This has a few problems (for example it confuses the management
5017 of stack temporaries), and is ugly. Now that the compiler is 2-pass
5018 we have a cleaner solution: In pass 1, we remember which actions
5019 were followed by ON-handlers. In pass 2, we use this information
5020 to generate appropriate code before an action.
5021 * except.c (push_handler, pop_handler): In pass 1, set up data
5022 structures (global_handler_list) to remember if an action has an
5023 ON-handler. In pass 2, digest this information, and setup
5025 * except.c, actions.h (pop_handler): Take an extra int arg.
5026 * except.c (emit_setup_handler): New function, with code (moved
5027 from chill_start_on) to emit code before an action that has a handler.
5028 * except.c (except_init_pass_2): New function.
5029 * parse.y (pass1_2): Call except_init_pass_2 before pass 2.
5030 * parse.y (POP_UNUSED_ON_CONTEXT): Don't call pop_sequence.
5031 * parse.y: Invoke POP_UNUSED_ON_CONTEXT and POP_USED_ON_CONTEXT
5032 in pass 1 as well as pass 2.
5033 * parse.y (BEGIN ... END): Re-arrange logic to avoid block_stack
5034 (local to ../stmt.c) getting out of sync.
5035 * actions.c (push_action): Don't need to emit a NOP,
5036 now that we're no longer moving sequences around.
5037 * actions.c (push_action): Call push_handler even in pass one.

5142 * typeck.c (build_chill_array_type): Update accordingly.

5784 * ch-expr.c (build_chill_indirect_ref): Handle MODE == NULL_TREE.
5786 * ch-expr.c (fold_set_expr): Handle OP1 == NULL_TREE (which happens
5787 for unary set operations).
5789 * ch-expr.c (build_chill_array_expr): Take new argument FORCE. All
5790 callers changed. All callers changed.
5792 * ch-convert.c (digest_structure_tuple): Handle SELECTED_VARIANT
5793 being NULL_TREE until we've started walking the list of values via
5794 the loop over VARIANTs.
5796 * ch-parse.y (build_chill_constructor): If we see an IDENTIFIER_NODE,
5797 treat it as an enum value (and hence constant). Also, only set
5798 TREE_STATIC if the constructor is indeed constant.
5799 * c-typeck.c (chill_initializer_constant_valid_p): If we see a
5800 VAR_DECL, test the TREE_CONSTANT field of the DECL_INITIAL, don't
5801 recurse on the DECL_INITIAL.
5803 Wed Jan 5 01:24:50 1994 Bill Cox (bill@cygnus.com)
5805 * Makefile.in: Add CHILL to LANGUAGES variable.
5806 * ch-actions.c (check_range): Call build_binary_op instead of
5807 fold, build to get the common types chosen.
5808 (cond_range_exception, cond_overflow_exception,
5809 cond_type_range_exception): Delete, obsolete.
5810 (chill_convert_for_assignment): Enable this, get particular
5811 about when to generate rangecheck code.
5812 * ch-expr.c (build_chill_function_call): Sketch in where to
5813 perform chill_convert_for_assignment on actual parameters.
5814 (build_chill_addr_expr): Correct compiler warning.
5815 * ch-loop.c (build_chill_iterator): Add runtime check for
5816 negative loop step expression.
5817 * ch-tree.h: Add prototype.
5818 * ch-typeck.c (chill_max_vary_array_ref): Correct misunderstanding.
5819 A varying array's length field counts the NUMBER of active array
5820 array entries, not the byte-length of them.
5822 Tue Jan 4 17:57:39 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5824 * ch-decl.c (do_decl): Call `suspend_momenary' if the
5825 converted constructor must live on the permanent_obstack.
5826 * ch-convert.c (convert): When building a new SET_TYPE
5827 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5828 * c-typeck.c (chill_initializer_constant_valid_p): Handle VAR_DECLs.
5830 * ch-typeck.c (chill_location): CONSTRUCTORS that are static
5832 * ch-satisfy.c (safe_satisfy_decl): Convert DECL_INITIAL of CONST_DECL
5833 on permanent_obstack if necessary.
5835 * ch-convert.c (digest_structure_tuple): When building a new SET_TYPE
5836 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5838 * ch-decl.c (do_decl): Fix handling of REFERENCE_TYPEs which
5839 the patch below helped to mess up.
5841 * ch-expr.c (build_chill_arrow_expr): Call `mark_addressable'.
5842 (build_chill_addr_expr): Take new argument ERRORMSG.
5843 All callers changed. Also, call `build_chill_addr_expr' where
5844 we used to call `build1 (ADDR_EXPR, ptr_type_node, ...)' since
5845 that now calls `mark_addressable' automagically.
5847 * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.
5848 This is needed because variables may appear in initialization
5849 statements, and their DECL_INITIALs are their values at
5850 initialization time.
5851 * ch-convert.c (digest_structure_tuple,digest_constructor): Changed
5852 to handle VAR_DECLs as initializers.
5854 * ch-convert.c (digest_structure_tuple): Copy elements of INITS so
5855 they aren't destroyed for later use.
5857 Tue Jan 4 15:25:30 1994 Bill Cox (bill@cygnus.com)
5859 * ch-expr.c (chill_expand_expr): Correct check-range lo_limit
5860 parameter for varying_array_ref calculations.
5861 (build_chill_indirect_ref): Prevent seg fault due to syntax error.
5862 * ch-typeck.c (build_chill_slice_with_range): Correct issuance
5863 of bogus error in votrics.
5864 (build_chill_slice_with_length): Change for debug tracability.

5868 * ch-convert.c (digest_structure_tuple): Fix phasing problem in
5869 handling variant record initializers.
5870 (various places): Change `pop_init_level' calls to match
5871 `push_init_level' wrt implicit variable.
5873 * ch-typeck.c (build_chill_slice): Convert the dynamic max index to
5874 `integer_type_node' before using it in comparisons. FIXME: should
5875 this be done in `chill_max_vary_array_index' by default?
5877 Tue Jan 4 00:24:14 1994 Bill Cox (bill@cygnus.com)
5879 * ch-actions.c: Fix comments.
5880 * ch-parse.y: Define caseaction_flag.
5881 (caseaction): Create new caseaction_flag node at the start,
5882 then free it at the end. Check it before the ELSE code.
5883 (expanded_case_label): Check the flag here. If set in either
5884 place, generate a jump to the end of the case.
5885 * ch-typeck.c (build_chill_slice_with_length,
5886 build_chill_slice_with_range): Add lots of compile-time
5887 parameter range checking.
5889 Mon Jan 3 21:49:04 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5891 * ch-convert.c (digest_structure_tuple): Call `push_init_level' with
5892 implicit==0 everywhere, not 1.
5893 (digest_constructor): Ditto.
5895 * ch-actions.c (check_range): Permit limits to be NULL_TREE.
5896 Also, hack out some dead code.
5897 * ch-typeck.c (build_chill_slice): Check varying and non-varying
5898 slice constructs for range failures.
5899 (build_chill_slice_with_range): Reindented, but not changed.
5901 * ch-typeck.c (chill_max_vary_array_index): New function.
5902 * ch-expr.c (chill_expand_expr): Call it.
5904 * ch-decl.c (var_data_id, var_length_id): New variables.
5905 (init_decl_processing): Initialize them. All calls to
5906 get_identifier (VAR_LENGTH or VAR_DATA) are now replaced
5907 by references to these variables. This simplifies the code
5908 w/o obscuring anything.
5910 Mon Jan 3 21:24:44 1994 Bill Cox (bill@cygnus.com)
5912 * c-typeck.c: Fix comment.
5913 * ch-actions.c (chill_expand_assignment): Error assigning to
5914 READONLY location. (PR_3903) Pass filename, linenumber
5915 to setbitpowerset runtime routine.
5916 * ch-decl.c (init_decl_processing): Add filename, linenumber
5917 parameters to setbitpowerset prototype.
5918 * ch-expr.c (build_chill_function_call): Error when passing a
5919 READonly location as a LOC or INOUT parameter.
5920 * ch-parse.y (mode): Correct code marking type as readonly.
5922 Mon Jan 3 19:03:55 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5924 * ch-actions.c (chill_expand_assignment): Disable code that defeats
5925 building varying array references.
5926 * ch-expr.c (chill_expand_expr): Add rangecheck code to
5927 VARY_ARRAY_REF case.
5928 * ch-typeck.c (build_chill_array_ref): Don't call an `expand_'
5929 function (in this case, `validate_varying_array_ref') when we're
5930 doing a `build_' operation.
5932 * ch-typeck.c (validate_varying_array_ref): Simplify interface
5933 since INDEX parameter can never meaningfully be an INDEXLIST.
5934 * ch-actions.c (expand_varying_length_assignment): Caller changed.
5936 Mon Jan 3 07:29:45 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5938 * ch-typeck.c (build_chill_cast): Set TREE_CONSTANT on NOP_EXPRs.
5939 * ch-convert.c (digest_structure_tuple): Switch to permanent_obstack
5940 if we need to build a CONSTRUCTOR for a SET_TYPE initializer.
5941 (digest_structure_tuple): If TREE_VALUE (VALUE) == NULL_TREE, don't
5942 call CH_COMPATIBLE or try to convert it to TREE_TYPE (FIELD). This
5943 can happen when constructors are output incrementally.
5944 * c-typeck.c (initializer_constant_valid_p): Handle SET_TYPEs.
5945 * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
5948 Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5950 * ch-convert (digest_structure_tuple): Handle SET_TYPEs. Also, call
5951 `convert' so we can handle INSTANCE types (and other anomolies)
5954 * ch-convert.c (digest_structure_tuple): Fixed variant
5955 structure initialization. Also fixed a typo (TYPE_NAME
5956 was being used on a FIELD_DECL instead of DECL_NAME).
5957 * c-typeck.c (initializer_constant_valid_p): Pass missing
5958 ENDTYPE argument on recursive call.
5959 (set_init_field): New function, needed by ch-convert.c change above.
5961 * ch-decl.c (layout_chill_variants): Added a FIXME next to an
5962 almost certain typo.
5964 * ch-expr.c (build_chill_arrow_expr): Call `build1' and set
5965 TREE_CONSTANT for static references.
5966 * ch-except.c (chill_start_on): Change calls to
5967 `build_unary_op' (which is C-specific) to `build_chill_arrow_expr'
5968 which has CHILL semantics.
5969 * ch-convert.c (convert): Ditto (albeit in some disabled code).
5971 Sat Jan 1 21:26:43 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5973 * ch-satisfy.c (safe_satisfy_decl): Reorder conditional test of
5974 TREE_CODE of DECL in case it's altered by actions in the switch.
5976 * ch-satisfy.c (satisfy): Undo abort added earlier on 1 Jan. CVS log
5977 mentions where to find code that triggers this case.
5979 * ch-actions.c (adjust_parm_or_field): Handle CONSTRUCTORS here as
5982 * ch-convert.c (digest_structure_tuple): Push to permanent_obstack if
5983 we're dealing with a CONSTRUCTOR that is TREE_PERMANENT.
5984 (digest_constructor): Ditto.
5986 Sat Jan 1 10:29:19 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5988 * ch-parse.y (handleraction,resultaction,assignaction,call): Modified
5989 so that CONSTRUCTORS are properly handled before being used.
5991 * ch-convert.c (chill_start_init): New function. All callers to
5992 `start_init' changed to call this function instead.
5993 (digest_struct_tuple): Defend against initialization machinery
5994 mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
5995 IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
5996 needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
5997 can be refered to throughout the compilation unit. Also remove an
5998 extraneous call to `process_init_element' erroneously added to the
5999 variant record sub-loop.
6000 (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
6001 CONSTRUCTORS of SET_TYPE.
6002 * ch-parse.y (build_chill_constructor): Refix typo. Also set
6003 TREE_STATIC if at top level.
6005 * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
6006 TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
6007 should have been called.
6009 * ch-convert.c (digest_struct_tuple): Restore code which tracks
6010 field initializations so that the compiler can deduce what variant
6011 initializations to assume.
6013 * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
6014 when we push into a scope that has a DECL with a CONSTRUCTOR as its
6017 * ch-parse.y (build_chill_constructor): Change the name of the
6018 parameter to something more meaningful. Fix typo. Also, handle case
6019 where element is an untyped CONSTRUCTOR.
6021 * ch-except.c (finish_handler_array): Set TREE_CONSTANT on
6022 constant ADDR_EXPRs.
6023 (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT
6024 on JBUF_REF (instead of calling `build1' which does not).
6026 * ch-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
6028 * ch-typeck.c (chill_expand_tuple): Deleted.
6029 * ch-parse.y (primval rule): Don't call `chill_expand_tuple';
6030 instead, use initialization machinery for CONSTRUCTORS that
6032 * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
6033 that are created here.
6034 * ch-satisfy (satisfy): Abort in case we would have called
6035 chill_expand_tuple. FIXME: some other code is needed here,
6036 but I don't know what yet.
6038 * ch-parse.y (build_chill_constructor): New function to
6039 propagate TREE_CONSTANT bits to CONSTRUCTORS.
6040 (untyped_expr rule): Use it.
6041 (primval rule): Use it.
6043 * ch-decl.c (do_decl): Call `finish_init'.
6044 * ch-convert.c (convert): If we spontaneously create a CONSTRUCTOR in
6045 this function, make sure the initialization machinery is set up.
6047 * ch-convert.c (digest_structure_tuple, digest_constructor): Add
6050 Fri Dec 31 11:31:01 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6052 * ch-grant.c (chill_finish_module_code): Mark ADDR_EXPR built by hand
6053 as being TREE_CONSTANT. Otherwise it gets bounded by the initializer
6056 * ch-decl.c (do_decl): Change in CONSTRUCTOR handling due to...
6057 * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
6058 rewritten to work with GCC's initialization code. The basic change
6059 was to keep the initializers in sync with the initialization
6060 machinery that `process_init_element' imposes. Both of these
6061 functions now return `void'.
6062 * ch-convert.c (convert): Changed calls to `digest_...' functions.
6064 FIXME: the code handling UNION_TYPE (and variant records) has not
6067 Fri Dec 31 15:32:56 1993 Bill Cox (bill@rtl.cygnus.com)
6069 * ch-lex.l (convert_number): Output the converted number if
6071 * ch-parse.y (signaldef): Set ignore_exprs correctly for a
6074 Fri Dec 31 13:17:48 1993 Bill Cox (bill@cygnus.com)
6076 * ch-parse.y: Cleanup handling of RETURN actions, to distinguish
6077 a RETURN without a value (which cannot have an exception
6078 handler) from a RETURN with a value (which can). Eliminate
6079 some shift/reduce and reduce/reduce conflicts.
6081 Thu Dec 30 17:42:32 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6083 * ch-inout.c (build_chill_writetext): Deal with 2 cases where
6084 types returned from `type_for_size' are not expected. FIXME.
6085 * ch-decl.c (init_decl_processing): Mark `char_type_node' unsigned.
6086 This is required when range checking is enabled.
6088 Thu Dec 30 14:28:25 1993 Bill Cox (bill@rtl.cygnus.com)
6090 DELAY CASE works now.
6091 * ch-decl.c (init_decl_processing): Move rest of tasking-related
6092 initialization into tasking_init().
6093 * ch-parse.y (delaycaseaction): Pervasive additions/corrections.
6094 (optsetprio): New non-terminal.
6095 * ch-tasking.c (get_task_name): Delete, obsolete.

6102 correct its functioning.
6103 (build_delay_case_end): Correct the code.
6104 (tasking_init): Lots of tasking-related code moved here from
6105 init_decl_processing.
6106 * ch-tree.h: Update, add prototypes.
6108 Wed Dec 29 10:13:10 1993 Bill Cox (bill@rtl.cygnus.com)
6110 * ch-expr.c (build_chill_indirect_ref): Revert change which
6111 failed full regression testing.
6112 * ch-lex.l (name_type_signal): Add debug output.
6113 * ch-parse.y (structured_variable): Add a debug variable.
6115 Wed Dec 29 02:05:51 1993 Bill Cox (bill@rtl.cygnus.com)
6117 * ch-decl.c (get_next_decl): Revert change which failed full
6120 Tue Dec 28 18:20:14 1993 Bill Cox (bill@rtl.cygnus.com)
6122 DELAY actions work now.
6123 * ch-decl.c: Correct spelling in comments.
6124 (get_next_decl): NULL out the decl's TREE_CHAIN before returning
6125 it, to prevent accidental access to the remembered_decls.
6126 (init_decl_processing): Add wait_event to runtime functions.
6127 * ch-expr.c (build_chill_indirect_ref): Prevent a syntax error from
6128 becoming a seg fault.
6129 * ch-grant.c: Correct a comment.
6130 * ch-loop.c: Delete/correct comments.
6131 * ch-parse.y (delaycaseaction): Add push/poplevel calls. Turn 'sorry'
6132 into rough draft of actual code.
6133 (delayaction): Don't make a new scope here, use get_unique_identifier
6135 (locdec): process event decls here, too.
6136 (mode): Add code to forbid READonly EVENT and BUFFER decls. Delete
6137 code which required EVENTs and BUFFERs to be declared at global scope.
6138 (simple_name_string): Add an EVENTNAME.
6139 * ch-satisfy.c (safe_satisfy_decl): Prevent a syntax error from
6140 becoming a seg fault.
6141 * ch-tasking.c (tasking_setup): Add the event queue's max. length
6142 as the 'entry_point' parameter in the list.
6143 (build_receive_case_start, build_receive_case_label): Defer
6144 calling runtime routine until we know whether we have a signal
6145 or a buffer to wait for.

6154 * gcc.c (CHILL SPECS): Delete references to -M -MM -MD -MMD
6155 options. Delete C-specific defines. Disable piping from
6156 pre-processor to cc1chill (even if -pipe is specified), since cc1chill
6157 rewinds its input for its second pass. Piping still works
6158 from cc1chill to as.
6160 Thu Dec 23 12:31:55 1993 Bill Cox (bill@rtl.cygnus.com)
6162 * ch-tasking.c (decl_tasking_code_variable): Assure that the
6163 tasking_code variable is allocated on the permanent obstack.
6164 (tasking_setup): Lots of changes - handle EVENT/BUFFER max.
6165 queue length (passed as the entry_point parameter).
6166 Other changes to variable names to increase 'self-documentation'
6167 the only kind GNU CHILL will get, for a while..
6169 Wed Dec 22 10:46:31 1993 Bill Cox (bill@rtl.cygnus.com)
6171 * ch-decl.c (do_seize): Delete - it's unused. Fix comments.
6172 * ch-loop.c (build_chill_iterator): Convert BY expression
6173 so loop involving a SET works. Additional errors generated
6174 for numbered SET expression as start or end expression.
6175 * ch-tree.h: Prototypes for future DELAY functions.
6176 * ch-typeck.c: Standard indentation.
6178 Tue Dec 21 15:30:57 1993 Per Bothner (bothner@kalessin.cygnus.com)

6188 * ch-lex.l (init_lex): Use new macro to make more terse.
6189 * ch-typeck.c (chill_equivalent): New function.
6190 Also check that ranges have the same bounds.
6191 * ch-typeck.c (my_build_array_ref): Add optional range-checking.
6192 * ch-typeck.c (chill_location): Handle COMPOUND_EXPR properly.
6193 Return 2 if also a referable.
6194 * ch-typeck.c (chill_referable): Re-define to use chill_location.
6195 * ch-tree.h (CH_EQUIVALENT): Re-defined to use chill_equivalent.
6197 * dbxout.c (dbxout_type): Output the type attribute "@S;" to
6198 distinguish a string from a char array, and to distinguish a
6199 bitstring from regulat (power)set. (Needed for Chill.)
6200 * dbxout.c (dbxout_type): Only check for baseclasses in
6201 type.binfo is a vector. (It is used in Chill for tagged unions.)
6203 Fri Dec 17 09:56:07 1993 Bill Cox (bill@rtl.cygnus.com)
6205 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
6206 ch-grant.c, ch-inout.c, ch-loop.c, ch-parse.y,
6207 ch-satisfy.c, ch-tasking.c, ch-tree.h, ch-typeck.c:
6209 * ch-actions.c (chill_expand_assignment): Error if assigning
6210 a value to a BUFFER or EVENT variable.
6211 * ch-expr.c (invalid_left_operand): Delete, unused.
6212 * ch-grant.c (tasking_setup): Call build_enum_tables.
6213 * ch-inout.c (get_final_type_and_range, build_enum_tables,):
6215 (build_chill_writetext): Lots of changes to support other
6216 basic CHILL data types.
6217 * ch-loop.c (build_chill_iterator): Lots of new code to check
6218 the expressions in a STEP loop.
6219 * ch-tasking.c (rc_state): Add fields to flag SIGNAL and BUFFER
6220 names in receivecasealternative. Generate error messages
6221 if they're mixed in the same receive case.
6222 (process_buffer_decl): Renamed from build_buffer_decl.
6223 * ch-tree.h: Fix prototypes.
6224 * ch-typeck.c (smash_dummy_type): Handle all four kinds of LANG_TYPE

6229 * ch-decl.c (push_scope_decls): Re-arrange some more, so
6230 that normal SEIZES (without ALL) are handled before SEIZE ALL.
6232 Wed Dec 15 13:01:22 1993 Bill Cox (bill@rtl.cygnus.com)
6234 * ch-loop.c (declare_temps): Calculate end-of-array pointer
6235 using correct type (NOT chill_integer_type).
6236 (begin_chill_loop): Build loop-bypass expression in the
6237 type of the start expression, not in the unsigned type.
6239 Tue Dec 14 15:41:32 1993 Per Bothner (bothner@kalessin.cygnus.com)
6241 * ch-decl.c (push_scope_decls): Re-arrange so that normal
6242 (non-seize) declarations are proclaim_decl'd *before* we
6243 handle the ALIAS_DECLs for seizes. The advantage is

6246 when a module has both GRANTs and SEIZE ALL.

7000 error message in pass 1.

7009 parameter to know whether to include an init expression.

7053 not error_mark_node.
7054 * ch-actions.c (chill_expand_assignment): Allow such borderline

7217 * ch-grant.c (chill_finish_compile): Add code to spoof
7218 get_file_function_name, so we don't get __tmp_s1_code,
7219 for example, as the module-level code's name.
7220 * ch-loop.c (build_temporary_variable, begin_for_range,
7221 init_loop_counter): Add parameter to decl_temp1 call.

7271 * ch-convert.c (digest_constructor): Convert element to element_type.
7272 * ch-parse.y (end_function): Use DECL_ARGUMENTS to check
7273 for parameterless process.
7275 Fri Oct 1 13:57:30 1993 Per Bothner (bothner@kalessin.cygnus.com)
7277 * ch-typeck.c (chill_location): New function.
7278 Based on lvalue_p, but also handle Chill-specific VARY_ARRAY_REF.
7279 * ch-typeck.c, ch-tree.h (CH_LOCATION_P), ch-convert.c: Use
7280 chill_location instead of lvalue_p.
7283 Fri Oct 1 11:28:42 1993 Bill Cox (bill@cygnus.com)

7299 ch-convert.c (convert): Use it.
7300 * ch-typeck.c (build_chill_slice): Take length rather than upper
7301 bound. This makes it easier to recognize that A(X UP LENGTH)
7302 really has fixed length. Also, if the argument is string,
7303 mark the slice as a string too. Also, handle varying strings.
7305 * ch-typeck.c (conflate_singleton_strings): New global.
7306 * ch-typeck.c (chill_similar): If conflate_singleton_strings is
7307 set (as it currently is), allow CHARS(1)/BOOLS(1) to be similar
7308 to CHAR/BOOL, as required by the 1984 version of Z.200.
7309 * ch-convert.c (convert_to_char): Convert CHARS(1) to CHAR.
7310 * ch-convert.c ( build_array_type_for_scalar): If input is string,
7312 * ch-convert (maybe_turn_scalar_into_arra), ch-tree.h: Removed.
7313 * ch-convert.c (convert): Convert CHAR to CHARS(1).
7315 This fixes 'X // := Y' and is also a general simplification.
7316 * ch-actions.c (chill_expand_assignment): Convert 'LHS OP := RHS'
7317 to 'LHS := LHS OP RHS' (using stabilize_reference on LHS).
7318 Also, call save_expr on RHS if a multiple assignment.
7319 * ch-parse.y (assignaction): Therefore, no longer need to call
7320 stabilize_reference on RHS.
7321 * ch-typeck.c (build_chill_modify_expr), ch-tree.h: Remove
7322 modifycode parameter. Make it the caller's responsibility to
7323 handle <assigning operator>.
7324 * ch-actions.c, ch-decl.c, ch-except.c, ch-expr.c, ch-grant.c,
7325 ch-loop.c: Fix calls to build_chill_modify_expr accordingly.
7327 Wed Sep 29 18:02:55 1993 Per Bothner (bothner@kalessin.cygnus.com)
7329 * ch-lang.c (string_index_type_dummy), ch-tree.h: New variable.
7330 * ch-decl.c (integer_minus_one_node), ch-tree.h: New variable.
7332 * ch-parse.y (arrayindex: modename): Remove useless code.
7333 * ch-satisfy.c (satisfy): Don't gag on string_index_type_dummy,
7334 * ch-tree.c (build_string_type): Pass string_index_type_dummy as
7335 the parent type of the index range.
7336 * ch-typeck.c (layout_chill_range_type): Recognize and handle
7337 string_index_type_dummy - specifically allow an empty range.
7339 Wed Sep 29 13:36:23 1993 1993 Bill Cox (bill@cygnus.com)
7341 * ch-convert.c (convert_to_reference): Check for loc-identity
7342 mismatches correctly (and remove one of those chill_compatible
7344 * ch-decl.c (decl_tasking_code_var): New function, called from
7345 push_extern_process and push_extern_signal.
7346 * ch-parse.y (end_function): Delete parameter. Check current_function_decl
7347 whether it's actually a process, and whether it has parameters.
7348 Make Michael's change simplifying the pass 2 test, preventing a seg
7350 (procedure, process): Change calls to end_function, remove
7351 code saving value from build_process_header. Delete redundant chill_
7352 phrases from some function calls.
7353 * ch-tasking.c: Remove some redundant _chill phrases from function
7355 * ch-tree.h: Remove some redundant _chill phrases from function
7356 names. Add the CH_VARYING_ARRAY_TYPE macro, call it from
7357 all relevant places.
7358 * ch-typeck.c: Use the new macro. Cast TREE_CODEs to chill_tree_code.
7360 Wed Sep 29 13:07:43 1993 Per Bothner (bothner@kalessin.cygnus.com)
7362 * ch-convert.c (convert_to_reference): Remove redundancies.

7364 with a recursive convert call.
7365 * ch-decl.c (do_decl): Add missing compatibility-checking
7366 of initializer (don't depend on convert).
7368 Tue Sep 28 00:02:25 1993 Per Bothner (bothner@kalessin.cygnus.com)
7370 * ch-tree.h (CH_LOCATION_P): New macro.
7371 * ch-typeck.c (layout_chill_range_type): Fix call to
7372 type_for_size, when figuring out a defaulted parent type.
7373 * ch-expr.c (build_chill_lower, build_chill_sizeof): Check
7374 for TREE_CODE_CLASS != 't' rather than == 'd'.
7375 * ch-expr.c (build_chill_function_call): Use CH_LOCATION_P
7376 to check for location, rather than TYPE_CODE_CLASS == 'd'.
7378 * ch-tree.c (build_string_type): Make 2-pass safe. Also,
7379 change parameter to be length, not index type.
7380 * ch-parse.y (mode2), ch-expr.c (build_concat_expr), ch-lex.l
7381 (build_chill_string): Modify callers of build_string_type accordingly.
7382 * ch-lex.l (check_newline): Don't look for # directive inside a
7384 * ch-grant.c (grant_array_type): Make more robust for char-
7385 and bit-strings (allow non-constant sizes). Change parameters
7386 and return types. (raw_decode_mode): Use grant_array_type
7387 for bitstrings. (otherwise): Fix grant_array_type callers.
7389 Mon Sep 27 16:57:57 1993 Per Bothner (bothner@kalessin.cygnus.com)
7391 Remove changes of Sep 15.
7392 * ch-tree.h (CH_SINGLETON_DOMAIN): Removed.
7393 * ch-typeck.c (chill_similar): Don't allow a singleton
7394 powerset to be similar to its domain.
7395 * ch-convert.c (convert_to_boolean): Don't convert a singleton
7396 SET_TYPE constructor to a Boolean.
7398 * ch-actions.c (chill_expand_assignment): Handle IN_EXPR on
7399 LHS of assignment, which is what we're current (temporarily?) using.
7401 Mon Sep 27 06:01:57 1993 Bill Cox (bill@rtl.cygnus.com)
7403 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
7404 ch-grant.c, ch-inout.c, ch-parse.y, ch-satisfy.c,
7405 ch-tasking.c, ch-tree.c, ch-tree.h, ch-typeck.c:
7406 -Wall cleanup. Add prototypes where missing.
7407 Delete unused variables. Cast uses of tree_codes
7408 to chill_tree_code, which they are.
7410 Sun Sep 26 13:09:57 1993 Bill Cox (bill@rtl.cygnus.com)
7412 * ch-decl.c (do_decl): Save initializer in pass zero
7414 * ch-lex.l: Fix comments, indentation.
7415 * ch-parse.y: Standardize error messages to use
7416 uppercase for CHILL keywords rather than quoting them.
7417 Suggestion from docs department.
7418 * ch-tasking.c: Pervasive changes to get processes to
7420 * ch-tree.h: Delete prototypes for functions whic
7421 I made static inside ch-tasking.c.
7423 Sun Sep 26 02:40:02 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7425 * ch-lex.l (yywrap): Call `check_newline' in case the file
7426 started with a line directive.
7428 Sat Sep 25 13:54:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
7430 * ch-decl.c: Expand pre-amble comment.
7431 * ch-decl.c (struct scope, push_module): Use new field
7432 tail_chain_module to build child-module list in order.
7433 (Just to make compiler debugging a little less confusing.)
7435 * ch-decl.c (struct scope): New field weak_decls.
7436 * ch-decl.c (find_implied_types): New interface. Now pre-pend
7437 new enum types to a given input list. This makes it easier to
7438 avoid duplicates, which should at least be more efficient.
7439 Also, handle FUNCTION_DECL.
7440 * ch-decl.c (bind_saved_names): Removed. Distribute its
7441 functionality over new functions (push_scope_decls, pop_scope_decls,
7442 build_implied_names, bind_sub_modules). The goal (which seems to
7443 have been more-or-less attained) was to fix weak name handling.
7444 * ch-decl.c (poplevel): Use new function pop_scope_decls.
7446 * ch-tasking.c (build_signal_struct, build_tasking_message_type):
7447 Use build_decl directly, rather than grok_chill_fixedfields
7448 (which depends on ignore_exprs and has more overhead).
7449 * ch-tasking.c (build_signal_struct): Construct the type
7451 * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
7452 than build_array_ref (which does C-specific "optimizations").
7453 (Hence move my_build_array_ref up earlier in the file.)
7455 Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7457 * ch-tasking.c: Declare static variable `void_ftype_void'.
7458 (chill_tasking_init): Initialize `void_ftype_void' here.
7459 (build_tasking_struct): Use, don't declare `void_ftype_void'.
7460 (generate_tasking_code_variable): Call `do_decl', not
7461 `decl_temp1' to declare TASKING_CODE_NAME.
7462 (tasking_setup): Drop into 1-pass mode so that all
7463 tasking-related declarations are installed in the global
7464 scope. Use correct CHILL types for initializers (since
7465 ptr_type_node doesn't have the right meaning for CHILL).
7466 Also, call `do_decl' instead of `decl_temp1' for
7468 (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
7469 `chill_finish_compile' in sync between passes.
7471 * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
7472 declarations on pass zero. Keep obstacks in sync, and always
7473 call `finish_decl' for pass zero declarations.
7474 (push_chill_extern_function): Keep obstacks in sync, and always
7475 call `finish_decl' for pass zero declarations.
7476 (build_enumerator): Ditto.
7477 (grok_chill_variantdefs): Change PASS test to exclude only
7479 (finish_struct): Ditto.
7480 * ch-expr.c (build_chill_component_ref): Ditto.
7481 (build_chill_binary_op): Ditto.
7482 * ch-tree.c (build_powerset_type): Ditto.
7483 (build_bitstring_type): Ditto.
7484 * ch-typeck.c (build_chill_range_type): Ditto.
7485 (build_chill_struct_type): Ditto.
7487 * ch-decl.c (build_chill_exception_decl): Clarify reasons for
7488 extra pushing and popping of obstacks.
7490 * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
7491 on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
7493 * ch-grant.c (chill_finish_compile): Clear out both
7494 MODULE_INIT_LIST and TASKING_LIST if either contains stuff
7497 * ch-parse.y (rccase_label): Add NAME rules so that pass one
7498 works w/o knowing we're parsing a signal. Simplify SIGNALNAME
7499 rules since we only get SIGNALNAME tokens in pass two.
7500 (sendaction): Ditto.
7501 * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
7502 BUFFERNAME on pass two. The grammar now handles this.
7503 * ch-decl.c (lookup_remembered_decl): Deleted.
7505 Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
7507 * ch-decl.c (lookup_remembered_names): Removed. It was being
7508 misused in ch-lex.l.
7509 * ch-lex.l (name_type_signal): Revert last change. Basically,
7510 we cannot use the C typedef/variable name trick in CHILL, due
7511 due to the language's 2-pass nature.
7512 * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
7514 * ch-tree.h (lookup_remembered_name): Comment out the prototype.
7516 Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7518 * ch-decl.c (do_decl, push_chill_extern_function): Change pass
7519 checks so the pass == 0 case is handled for built-in types.
7520 (push_modedef): Add check for error_mark_node.
7521 (lookup_remembered_decl): New function.
7522 (pushlevel, poplevel) Change pass checks.
7523 (pushdecl): Check type as well for NULL.
7524 (build_enumerator): Handle pass == 0 case.
7525 * ch-lex.l: Use lookup_remembered_decl to get lastiddecl
7527 * ch-parse.y: Set pass to zero to indicate initial decl processing.
7528 Replace NAME references with SIGNALNAME references.
7529 (startaction): Only check copy number if not ignoring actions.
7530 Always call build_chill_start_process.
7531 (optstartset): Don't lookup the instance name.
7532 * ch-tasking.c (generate_tasking_code_variable): Replace
7533 do_decl call with decl_temp1 call.
7534 (build_chill_start_action): Check for ignore_actions here.
7535 (build_tasking_message_type): Layout the type.
7536 (rc_state_type): New structure to keep nested receive-case
7538 (build_chill_receive_case_start, build_chill_receive_case_end):
7542 Fri Sep 24 04:19:15 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7544 * ch-tasking.c (build_chill_receive_case_start): `namedecl'
7545 should be a _DECL, not an IDENTIFIER_NODE.
7547 Thu Sep 23 18:18:24 1993 Per Bothner (bothner@kalessin.cygnus.com)
7549 * ch-decl.c (find_implied_types): Handle VAR_DECLs.
7551 * ch-decl.c (print_lang_identifier): Print IDENTIFIER_OUTER_VALUE.
7552 * ch-actions.c (chill_expand_result): Allow value-less RETURN.
7553 * ch-expr.c (resolve_component_ref): Recognize error_mark.
7555 * ch-convert.c (digest_constructor): Handle a nested powerset tuple.
7556 * ch-satisfy.c (satisfy): Use return value of layout_chill_range_type.
7557 * ch-typeck.c (chill_similar): Repeatedly get parent modes
7558 of ranges, not just once.
7559 * ch-typeck.c (chill_root_resulting_mode), ch-tree.h: New function.
7560 * ch-typeck.c (layout_chill_rang_type): Re-do type-checking
7561 to follow Blue Book better (check for Compatibility).
7563 * ch-tree.h (CH_ROOT_RESULTING_MODE): New macro.
7564 * ch-lex.l (use_seizefile_name, current_seizefile_name), ch-tree.h:
7565 New variables. The latter replaces in_seizefile.
7567 Changes to store in the new DECL_SEIZEFILE field each seize
7568 ALIAS_DECL the name in the most recent use_seize_file directive.
7569 (This requires that use_seize_file directives written to the
7570 grant file be written before the SEIZEs that need it.)
7571 Allow clashing declarations granted into the global scope
7572 (produce a warning), but remember the seizefile case from
7573 (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
7574 The a SEIZE will select the granted decl that matches its
7575 DECL_SEIZEFILE (in other words: grants from the most recent
7576 use_seize_file will be preferred).
7577 * ch-tree.h (DECL_SEIZEFILE), ch-tree.def: New macro.
7578 * ch-tree.h (global_value, IDENTIFIER_GLOBAL_VALUE): Renamed
7579 to outer_value, IDENTIFIER_OUTER_VALUE.
7580 Changes to cause the use_seize_file directives to be written
7581 out in order as they're seen in source.

10264 (start state 'ccitt'): Deleted, unused. Moved unused, but reserved,
10265 tokens to NORMAL state.
10266 (compiler_directive): Replaced by equal_number. Now the only
10267 recursive call to yylex happens in check_newline at the beginning
10270 Sat Apr 10 09:55:50 1993 Bill Cox (bill@rtl.cygnus.com)
10272 * ch-actions.c (build_chill_case_expr): Added from ch-parse.y.
10273 * ch-lex.l (ENTRY, PERVASIVE, ROW, STEP): Add token recognition to
10275 * ch-parse.y (case_expr): Move code into ch-actions.c. There will

10278 * ch-tree.h (build_chill_case_expr): Add prototype.
10279 * ch-typeck.c (build_chill_cast): Allow untyped_expr - just assign the
10280 type to the expr. Check for CASE_EXPR, call expand_case_expr.
10282 Sat Apr 10 01:10:51 1993 Per Bothner (bothner@rtl.cygnus.com)
10284 * ch-parse,y (in_pseudo_module): New variable. Try if we're
10285 in a seizefile, but not in a module nested in the seizefile.

10298 * ch-lex.l: Re-write to use start states, to avoid calling
10299 yylex() recursively.
10300 * ch-lex.l (compiler_directive); This is now obsolste. FIXME.
10301 * ch-lex.l: Call push_module and pop_module when reading a
10302 seizefile. This creates a pseudo-module.
10303 * ch-parse.y: Clean up handling of empty declarations and
10304 action statements; semicolons are now optional a number of
10306 * ch-parse.y: Remove some bogus tests for "statement
10307 out of sequence" (they're both legal and work).
10308 * varasm.c (mak_function_rtl): Remove kludge that may
10309 not be necessary (and loses anyway).
10311 Fri Apr 9 09:37:38 1993 Bill Cox (bill@rtl.cygnus.com)
10313 * ch-expr.c (chill_expand_array_assignment): Remove false error about

10330 which is the list (in order) of decls in the module.
10331 Don't reverse the getdecls() list; that is handled by caller.
10332 * ch-grant.c (chill_grant): Test that a declaration is
10333 visible before writing it.

10349 assignment, clean up.
10350 * ch-typeck.c: Add prototype for require_complete_type.

10360 * ch-decl.c (massage_param_node): New function.
10361 It handles the LOC/IN/OUT/INOUT parameter distinction,
10362 as well as calling build_chill_array_parm_type if needed.
10363 * ch-tree.h (massage_param_node): New prototype.
10364 * ch-decl.c (push_parms): Use new massage_param_node().
10365 * ch-parse.y (pmodearg): Use new massage_param_node().

10374 the pseudo struct type is allocated on the permanent_obstack.
10375 * ch-parse.y (location): Remove thinko.
10376 * ch-actions.c (chill_comptypes): Comment out test for

10389 Mon Apr 5 19:56:56 1993 Bill Cox (bill@rtl.cygnus.com)
10391 * ch-actions.c, ch-decl.c: Use tree_int_cst_equal and integer_zerop

10411 Fri Apr 2 21:55:14 1993 Per Bothner (bothner@rtl.cygnus.com)
10413 Major re-write of New module/seize/grant stuff.
10414 Now, a grantfile is a spec module and contains all the
10415 top-level declarations of the granting module, not just
10416 those that are granted. It also contains explicit grant
10417 statments naming those declared names that are granted.
10418 It also has seize statements and use_seize_file directives
10419 to correctly handle transitive dependencies.
10421 * ch-parse.y: Change to allow multiple modules per source file.
10422 Allow spec modules (including quasi definitions) as well as
10424 Allow spec modules inside normal modules; these behave as if
10425 they were outermost. This violates the Blue Book, but is
10426 needed by the new grantfile mechanism. (A grant file is a
10427 spec module that gets included by the use_seize_file directive.)
10428 * ch-parse.y (struct module *current_module, push_module,
10429 pop_module): Support module nesting (for spec modules only).
10431 * ch-tree.h (struct module): New.
10432 * ch-grant.c (granted_decls): New list of declarations
10433 that have been granted into the outermode pseudo-module.
10434 * ch-grant.c (decode_mode): If the decl has a name,
10435 always write the name, not just if the decl has already
10436 been written. Since we write out all decls, we can assume
10437 it will be written later, and depend on the forward
10438 declaration kludges to catch it.
10439 * ch-grant.c (decode_decl): Don't write out _EXTERN.
10440 Instead write out standard (Blue Book) quasi-definitions.
10441 * ch-grant.c (push_granted): New function.
10442 * ch-grant.c (seize_implied_names): New function. Re-write
10443 how set element names are seized when a set type is seized.
10444 * ch-grant.c (chill_seize): Work by seraching the
10445 granted_decls list and copying the declaration.
10446 * ch-grant.c (chill_grant): Write all declarations
10447 declared in this module. Write GRANT statements for
10448 those granted. seize statements for decls seized from
10449 other modules. Write extra syntax to make a complete
10451 * ch-grant.c (grant_use_seizefile): Copy use_seize_file
10452 directives into grant file.
10453 * ch-lex.l (setup_seizefile_read): Call grant_use_seizefile.
10455 * ch-lex.l (struct input_state, current_input_state,
10456 push_input_file, pop_input_file): New (type, variable,
10457 function*2). Used to save and restore state on an input file.
10458 * ch-lex.l: Clean up to handle nested input seizefiles
10459 (needed by new grant/seize mechanism.
10460 * ch-lex.l (skip_to_end_of_directive): New function.
10461 * ch-lex.l (compiler_directive: USE_SEIZE_FILE): Make sure
10462 we skip to the end of the directive *before* we switch
10464 * ch-lex.l (setup_seizefile_read): Prevent reading the
10465 same seizefile twice (otherwise likely with new grant/seize).
10466 * ch-lex.l: Recognize SPEC. Misc cleanups.
10468 * ch-parse.y: Fixed foreward references of types.
10469 Removed the unknown_type_node crock.
10470 * ch-decl.c: Remove all uses of unknown_type_node.
10471 Check for TYPE_SIZE zero instead.
10472 * ch-decl.c (fixup_unknown_type): Make sure new mode
10473 gets copied into old mode. Merge their variant chains.
10474 * c-decl.c (lookup_name_current_level): Make non-static.
10475 * ch-decl.c (lookup_name_current_level): No longer needed.
10477 * ch-parse.y (call): Allow an implicitly defined function
10478 name following the CALL keyword.
10479 * ch-tree.h (struct lang_identifier): Add implicit_decl,
10480 and make sure order of fields matches c-tree.h.
10482 * ch-actions.c (lang_init, build_allocate_memory_call,
10483 build_allocate_globals_memory_call): Fix names (add initial '_')
10484 and prototypes of _allocate_[global_]memory (2nd param is ref).
10485 Use build_chill_function_call, not build_function_call,
10486 so the reference parameter gets handled.
10487 * ch-actions.c. (lang_init): Make sure boolean_{true,false}_node
10488 have boolean_type_node as their types.
10489 * ch-actions.c (build_chill_lower, build_chill_upper): Fix to
10490 work for arrays with BOOLEAN_TYPE ranges (and simplify some).
10492 * ch-except.c: Make sure an end_label is generated,
10493 and jump to it if there is no exception.
10495 * ch-convert.c (convert_to_reference): Strip off NOP_EXPR casts.
10496 * expr.c (expand_expr): Handle NOP_EXPR as Chill-style casts.
10497 (Need cleaning up and FSF installation!)
10498 * ch-parse.y: If taking the address of a cast, move the
10499 ADDR_EXPR inside the NOP_EXPR.
10501 * ch-typeck.c (my_build_array_ref): Simplified, more suitable
10502 versions of build_array_ref from c-decl.c. (E.g. don't barf
10503 if index type is char or bool.)
10504 * ch-typeck.c (build_chill_array_ref): Use my_build_array-ref.
10506 * ch-typech.c (build_chill_bin_type): New function.
10507 Support BIN(N) range type specification.
10508 * ch-parse.y (mode2), ch-lex.l: Recognize BIN(N).
10510 * ch-tree.h (CH_SIMILAR): Redefine in terms of chill_similar.
10511 * ch-typeck.c (chill_similar): New function. Recognize that
10512 that range types are similar to their parent types.
10514 * ch-tree.h: Declare flag_local_loop_counter.
10515 * ch-loop.c: Whether the loop variable is local to the loop
10516 in now controlled by flag_local_loop_counter, instead of
10517 #ifdef'd on CREATE_SCOPE.
10518 * ch-actions.c (lang_decode_option): Recognize flags
10519 "-f[no-]local-loop-counter".
10520 * toplev.c (lang_options): Add Chill flags -f[no-]local-loop-counter.
10522 * varasm.c (make_function_rtl): Due to problems with forward
10523 references, don't rename nested functions in Chill. (Kudge!)
10525 Sun Mar 28 10:12:45 1993 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10527 * ch-lex.l (push_back, readstring): Fix prototypes.
10529 Fri Mar 26 18:32:15 1993 Bill Cox (bill@rtl.cygnus.com)
10531 * ch-parse.y: Put %type directives back into alpha order.
10532 (variant_alternative): Simplify error_mark test.

10538 * ch-parse.y (get_type_of): Add function to deal with possible fwd
10539 declared type name. Call it from lotsa places. Add lotsa checks

10546 * ch-parse.y (action): Add recognition for allocate_memory and
10547 allocate_global_memory system calls.
10548 (mode2): Remove ill-conceived error check that broke REFs to
10549 as-yet-undeclared types. Check for IDENTIFIER_NODE, lookup its
10550 DECL if there, pass TREE_TYPE of decl to build_pointer_type.
10551 (variantfields, varianthack): Clean up.
10552 (variantfield): Check for IDENTIFIER_NODE, lookup its DECL if
10553 there, pass TREE_TYPE of decl to grok_fixedfields.
10554 (labellist): Explicitly assign error_mark_node to signal error.
10555 * ch-typeck.c (chill_compatible): Report FALSE for bad parameters,
10556 rather than seg faulting.

10588 array and its type get on the permanent obstack.
10589 * ch-grant.c (write_grant_file): Don't write the _INIT=name
10590 specifier: It isn't needed, and loses (because of funny
10591 characters in the chill_initializer_name).
10592 * ch-decl.c (push_synmode): Set TYPE_NAME(mode) = syndecl.
10593 * ch-lang.c (finish_chill_enum): Don't allocate a dummy
10594 TYPE_DECL for the enum. I don't think it is needed (?),

10599 * ch-grant.ch (raw_decode_mode): New function, based on old
10601 * ch-grant.c (decode_mode); This is now just a wrapper around

10635 was intended to be equality test. Remove unused variables.
10636 * ch-tree.h: Add prototype. Remove unused EXCP_CODE enumeration, and
10637 prototyping editorial comments.
10638 * ch-typeck.c: Disable generation of code to validate array index for
10639 now. Should be done as a call-back from more generic array_ref code.
10640 Clean up parameter checking. Remove unused variables.
10642 Fri Mar 12 11:57:32 1993 Bill Cox (bill@rtl.cygnus.com)

10762 * expr.c (expand_expr): Use actual library name for __inpowerset
10764 * stor-layout.c (variable_size): Disable complaint about variable-
10765 size type or decl at file scope. Perhaps later this s.b. a warning.

10773 actual library names. Change references to boolean_type_node
10774 to references to the TREE_CODE == BOOLEAN_TYPE, to follow the
10776 build_set_expr: Remove length parameter, call powersetlen() instead.
10777 remove handling of CHAR arrays - they're handled in build_char_array_expr.

10779 need bitcount instead.
10780 build_chill_compound_expr, internal_build_compound_expr: Copy from C
10781 version that does stuff we don't want.
10782 build_binary_op: Check for in_size_in_bytes return < 0, indicating

10788 build_chill_length: Move VARYING array handling before regular char
10790 * ch-expr.c chill_expand_expr: Disable concatenate code - we need to
10791 the VARYING status of the target to do this correctly. Use powersetlen
10792 for the powerset operations, not a byte length.
10793 * ch-loop.c: Make CREATE_SCOPE #define to enable creation of a new scope
10794 for each CHILL loop, as Z.200 requires. Add powerset and error flags
10795 to loop structure. Evaluate user's powerset expression into a temp,
10796 scan it destructively with __ffsetclrpowerset or __flsetclrpowerset
10797 for powerset loop. Only do loop-end assignments if NOT a powerset
10798 loop, which has much less overhead now.

10844 comes out error_mark_node, set ERRONEOUS.
10846 * ch-actions.c (build_chill_binary_op_1): If EXP is NULL_TREE,
10849 * ch-action.c (chill_comptypes): Test for structural
10850 equivalence of enums.

11016 * ch-lex.l (convert_bitstring), Changed SET_TYPE_CONSTRUCTOR to
11017 take a list of elements which are in the set. This corresponds

11020 New functions, to expand SET_TYPE CONSTRUCTORs.
11021 * varasm.c (output_constructor): Use pack_set_constructor

11027 things in the correct order.
11028 * c-typeck.c (chill_initializer_constant_valid_p): Kludge
11029 needed to export a static function.
11030 * ch-typeck.c (convert): Avoid needlessly (and lossingly) calling
11031 chill_expand_tuple to convert fix string to varying.
11032 * ch-actions.c (build_chill_binary_op): Promote short
11033 integer operands if needed (otherwise emit routines barf).

11036 * ch-parse.y (location): If IDENTIFIER is a CONST_DECL

11062 * ch-parse.y: Add working exception handling support.
11063 * ch-lex.l, ch-parse.y: Prefer standard type terminology
11064 (BOOLS, CHARS) even though non-standard (BITS, CHAR) is ok.
11065 * ch-grant.c: Fix various problems related to granting
11066 types such as bitsets.
11067 * ch-tree.c (build_bitstring_type): Set TYPE_MIN_VALUE
11068 to distinguish bitstrings from powersets (in the same way
11069 we distinguish char strings from char arrays).
11070 * ch-tree.h: New macro CH_BOOL_TYPE_P.
11071 * ch-tree.h, ch-actions.c (lang_init), ch-grant.c (decode_mode):
11072 Undo kludge where integer_type_node was hardwired to 16 bits.
11073 Make integer_type_node etc have the same size as in cc1.
11074 New types chill_integer_type_node and chill_unsigned_type_node
11075 that correspond to the Chill source types INT and UINT.
11076 For now, these match the C 'short' types, but that should
11077 become a configuration option later,

11081 * ch-actions.c (build_chill_unary_op): allow NOT of a set.

11088 * ch-loop.c (begin_chill_loop, end_chill_loop): remove
11089 emit_nop() calls - they now (since exceptions) cause seg faults.

11092 * ch-tree.h: remove prototypes added to c-tree.h.
11093 * ch-typeck.c (build_chill_array_ref): correct getting domain

11099 * ch-tree.def: add a new tree type - just for varying array
11100 references. We were using ARRAY_REF, but the underlying C
11101 code also generates that one.
11102 * ch-convert.c, ch-expr.c, ch-typeck.c: use the new tree type.
11104 Sun Feb 7 17:33:17 1993 Bill Cox (bill@rtl.cygnus.com)

11122 * ch-actions.c: Adjust interface to cause_exception accordingly.
11123 * ch-typeck.c (build_chill_array_ref): Cause rangefail if
11124 index > limit, not >= limit.

11130 FUNCTION_TYPE, not FUNCTION_DECL.
11131 nreverse arg list to build_chill_array_ref.

11575 newlines and check for # directives.
11576 * ch-lex.l (syntax): Don't recognize #-directives; these
11577 are now handled by check_newline.
11578 * ch-actions.c (lang_init): Call the modified version of
11579 check_newline(). Do this at the *after* we've initialized
11580 standard types, so this can be done while lineno is still 0.
11582 Sat Jan 2 10:57:20 1993 Bill Cox (bill@cygnus.com)
11584 * ch-hash.h, chill.gperf: add remaining reserved words.
11586 Sat Jan 2 09:59:55 1993 Bill Cox (bill@cygnus.com)
11588 * ch-tree.h, ch-parse.y, ch-lex.l: add remaining reserved words,
11589 names for exceptions
11591 Fri Jan 1 12:30:31 1993 Fred Fish (fnf@cygnus.com)
11593 * ch-tree.h (JOINER): Define joiner character the same way
11595 * ch-grant.c (chill_start_module_code): Use JOINER character
11596 to implement name mangling for the initializer function name.
11597 Algorithm is designed to be simple, distinct from C++ mangled
11598 symbols, and easy to convert to demangled form.
11600 Thu Dec 31 10:30:51 1992 Bill Cox (bill@rtl.cygnus.com)
11602 * ch-expr.c: make array assignments work with indirect refs.
11603 * ch-actions.c: prepare for array parameter handling.
11604 * ch-loop.c, ch-parse.y, ch-tree.def, ch-typeck.c: clean up.
11606 Thu Dec 31 15:29:20 1992 Per Bothner (bothner@rtl.cygnus.com)
11608 * ch-lex.l (yy_input): Re-write to return more than one
11609 character at a time (execpt when reading seize-files).
11610 Don't increment lineno until we start reading the next line.
11611 This fixes some off-by-one errors in lineno.
11613 Wed Dec 30 16:15:23 1992 Per Bothner (bothner@rtl.cygnus.com)
11615 * ch-convert.c: Assume use of new common.c.
11616 * ch-convert.c (convert_to_reference, convert_from_reference):
11617 New routines, to handle loc-identity declared variables and
11618 LOC parameters (both of which are implemented as references).
11619 * ch-lang.c (convert_to_boolean, convert_to_char): Move to
11620 ch-convert.c, where they would seem to belong.
11621 * ch-convert.c (convert): New function, since we no longer
11622 link in c-convert.c.
11623 * ch-expr.c (chill_expand_assignment): Handle by calling
11624 convert() instead of chill_comptypes().
11625 Also handle the LHS being a reference.
11626 * ch-parse.y: Add a procedure call as an action.
11627 * ch-parse.y (locdec, optlocinit): Move handling of
11628 loc-identity declarations from optlocinit to locdec
11629 - and add working semantics for it.
11630 * ch-parse.y (seizestatement, visibilty_stmt): Simplify.
11631 * ch-parse.y (grantstatement etc): Don't bother making list.
11632 * ch-lex.l: #include <sys/types.h> before <sys/stat.h>.
11634 Wed Dec 30 16:06:55 1992 Bill Cox (bill@rtl.cygnus.com)
11636 * ch-parse.y, ch-expr.c: add support for declaring & assigning
11638 * ch-typeck.c: allow VARYING structures in assign_type_to_expr.
11640 Tue Dec 29 15:28:48 1992 Bill Cox (bill@cygnus.com)
11642 * ch-actions.c: implement expressions of arrays of char,
11643 ( concatenation, relationals ), correct type of code parameters
11644 * ch-expr.c: correct type of code parameters
11646 Tue Dec 29 11:16:19 1992 Bill Cox (bill@cygnus.com)
11648 * ch-decl.c: cleanup.
11649 * ch-parse.y: put emit_line_note() calls in lotsa places,
11650 per Fred's request; be sure that statements get counted also.
11651 * ch-lex.l: standardize function headers.
11653 Tue Dec 29 10:41:56 1992 Fred Fish (fnf@cygnus.com)
11655 * ch-decl.c (start_chill_function): Always return 1, rather
11656 than a random value.
11657 * ch-lex.l (check_newline): Add a version for chill that
11658 just snarfs the right value for main_input_filename out of
11659 the first line of the input file, without disturbing the
11660 lexer state or requiring it's assistance.
11661 * ch-actions.c (lang_init): Call check_newline, like the
11662 other language frontends, to get main_input_filename set
11663 from first line of input file.
11665 Mon Dec 28 18:49:01 1992 Bill Cox (bill@cygnus.com)
11667 * ch-parse.y: clean up conflicts. The remaining one is
11670 Mon Dec 28 17:28:40 1992 Bill Cox (bill@cygnus.com)
11672 * ch-parse.y, ch-lex.l, ch-actions.c: add stubs for I/O,
11673 clean up some parser conflicts.
11675 Mon Dec 28 15:00:20 1992 Bill Cox (bill@cygnus.com)
11677 * ch-parse.y, ch-lex.l: add keywords and parsing for most of
11680 Sat Dec 26 20:48:23 1992 Fred Fish (fnf@cygnus.com)
11682 * chillrt/chillrt0.c: Oops, SVR4 doesn't need leading '_'
11683 on build_exceptions.
11685 Sat Dec 26 11:00:36 1992 Fred Fish (fnf@cygnus.com)
11687 * ch-grant.c (chill_finish_module_code): Call
11688 assemble_constructor_alias rather than assemble_constructor.
11689 * varasm.c (assemble_constructor_alias): New function,
11690 like assemble_constructor, but also handles the case where
11691 ASM_OUTPUT_CONSTRUCTOR is not defined and GNU ld is not
11692 being used. Emits a symbol table alias name with the correct
11693 prefix for collect to find and add to the __CTOR_LIST__.
11694 * chillrt/chillrt0.c: Build on previous hack that gets
11695 _build_exceptions into the __CTOR_LIST__, to make it work
11696 for both the non GNU-ld case and for the SVR4 case.
11698 Tue Dec 22 18:24:55 1992 Bill Cox (bill@cygnus.com)
11700 * ch-loop.c: clean up location enumeration - one more

11711 Mon Dec 21 14:58:39 1992 Bill Cox (bill@cygnus.com)
11713 * ch-parse.y, c-decl.c: Add Jukka's Pascal WITH code.
11714 ch-loop.c: rough draft of location enumeration
11715 ch-lex.l, ch-expr.c, ch-decl.c: minor cleanup
11716 ch-actions.c: finish making pred() and succ() work.
11718 Mon Dec 21 10:04:35 1992 Bill Cox (bill@cygnus.com)
11720 * ch-actions.c: allow pred(char) and succ(char).
11722 Sun Dec 20 16:04:28 1992 Bill Cox (bill@cygnus.com)
11724 * ch-expr.c, ch-actions.c, ch-parse.y, ch-loop.c,
11725 c-expr.c: make DO WITH work.
11727 Sun Dec 20 12:22:53 1992 Bill Cox (bill@cygnus.com)
11729 * ch-loop.c, ch-actions.c, ch-typeck.c: powerset loops
11732 Sat Dec 19 14:20:23 1992 Per Bothner (bothner@cygnus.com)
11734 * c-typeck.c (process_init_constructor): Add warning if
11735 there is a duplicate default initializer element.
11736 * ch-typeck.c (chill_give_type_to_expr): New function,
11737 to handle coercion of an expression to context-given type,
11738 Takes care of untyped tuples, and case expressions.
11739 * ch-decl.c (do_decls), ch-typeck.c (chill_expand_return,
11740 chill_expand_result), ch-parse.y <assignaction>:
11741 Use chill_give_type_to_expr().
11742 * ch-typeck.c (chill_handle_case_label): New parameter list,
11743 to handle the (new) conventions for <case_label>, including
11744 default elements and ranges.
11745 * ch-parse.y <expanded_case_label>, ch-typeck.c
11746 (expand_case_expr): Use new version of chill_handle_case_label.
11747 * ch-decl.c (push_syndecls): Change parameters: Instead of
11748 TREE_LIST representing a compete <synonym definition statement>,
11749 just pass the parts of a single <synonym definition> as 3
11750 different parameters. Also, use chill_give_type_to_expr(),
11751 to handle untyped tuples in the RHS.
11752 * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct
11753 a tree - just call push_syndecls() on each <synonum_definition>
11755 * ch-parse.y (exprlist_get_single): Remove; no longer needed.
11756 * ch-parse.y: Handle <tuple> without mode name diferently from
11757 <tuple> with mode name. The latter is a <primval> that can be
11758 in most contexts, but if the <mode name> is missing, the <tuple>
11759 is only allowed in certain contexts. Use the new non-terminal
11760 <untyped_expr> to indicate those contexts where untyped tuples
11761 (and case expressions) are valid because the expression gets a
11762 type from its context (such as the RHS of an assignment).
11763 Use chill_give_type_to_expr in those contexts.
11765 Sat Dec 19 14:01:26 1992 Bill Cox (bill@cygnus.com)
11767 * ch-actions.c, ch-loop.c, Makefile.in: looping stuff.
11769 Sat Dec 19 10:16:20 1992 Bill Cox (bill@cygnus.com)
11771 * ch-parse.y: clean up warning messages from byacc. bison
11772 still complains thrice.

11776 * ch-actions.c (maybe_chill_comptypes): Delete unused
11778 (chill_comptypes): Add new parameter ERRSTR. All callers
11780 (build_chill_binary_op): Fix indentation to match GNU coding
11783 Fri Dec 18 08:18:13 1992 Bill Cox (bill@rtl.cygnus.com)
11785 * ch-parse.y, ch-expr.c, ch-actions.c, expr.c: major

11795 a default initializer element.
11796 * ch-parse.y: Implement default elements for tuples
11797 (as in '(else):' and '(*):' ).
11799 * ch-parse.y: Previous change to dis-ambiguate case-labels
11800 seems to have allowed getting rid of all of the expr_or_list hair.
11801 * ch-decl.c (do_decls): Undo Tiemann's change to "Handle
11802 initialization of multiple variables by a tuple" - the
11805 Wed Dec 16 11:17:53 1992 Bill Cox (bill@cygnus.com)
11807 * ch-parse.y: complete re-write of DO statement handling.
11808 now operational, except WITH is stubbed out. Improved
11809 syntax error message.
11810 * ch-actions.c: DO support: high_domain_value(), low_domain_value ().
11811 * ch-expr.c: fixes to IN_EXPR handling.
11813 Tue Dec 15 17:15:13 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11815 * ch-grant.c: Add casts to alloca return to avoid compiler warning.
11816 * ch-lex.c: Likewise.
11818 * Makefile.in (ch-lex.c): Delete incorrect free declaration added
11819 by flex to avoid compiler error.

11824 variables by a tuple.
11826 * ch-decl.c (do_decls,start_chill_function): Make DECL public
11827 if we're doing a GRANT ALL at top level.
11829 * ch-lang.c (build_range_type): Deal with typecast to CHAR in
11832 * c-typeck.c (digest_init): SET_TYPE is not a scalar type.
11833 BOOLEAN_TYPE and CHAR_TYPE are scalar types.
11835 Mon Dec 14 14:58:32 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11837 * ch-lex.l (get_chill_{linenumber,filename}): New functions.
11838 (convert_number): Use LONG_TYPE_NODE instead of INTEGER_TYPE_NODE.
11840 Mon Dec 14 13:36:44 1992 Bill Cox (bill@cygnus.com)
11842 * expr.c: install and test newer Pascal IN_EXPR code,
11843 but don't activate it - it's very verbose.
11845 Mon Dec 14 00:22:49 1992 Fred Fish (fnf@cygnus.com)
11847 * Makefile.in (LANGUAGES): Add chill.

11863 Sun Dec 13 14:07:32 1992 Bill Cox (bill@cygnus.com)
11865 * ch-actions.c: fix unary operations, modulus ops,
11866 (discovered after extending regression tests).
11868 Sun Dec 13 12:16:32 1992 Bill Cox (bill@cygnus.com)
11870 * resync with Michael and Wilfried
11872 Sun Dec 13 09:11:25 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11874 * ch-parse.y (output_constant): Fixed some whitespace
11876 * ch-tree.h: Add declarations for new chill functions that
11877 have been implemented but not (yet) declared.
11879 Sat Dec 12 00:17:23 1992 Per Bothner (bothner@cygnus.com)
11881 * c-typeck.c (process_init_constructor): Warn about duplicate
11882 labels for labelled initializer elements.
11883 * ch-lex.l (various operator tokens, such as "+"): Don't
11884 set yylval.code to a TREE_CODE; this is better done in parser.
11885 * ch-parse.y: Some work with case labels and tuples.
11886 Get literal range as tuple (and case) labels working.
11887 Fix some problems introduced by recent grammar overhaul.

11891 * ch-actions.c, ch-parse.y ch-tree.h ch-expr.c, ch-typeck.c:
11892 got long, real expressions working. We can also call a func-
11893 tion and use its return value.
11895 Thu Dec 10 14:45:17 1992 Per Bothner (bothner@cygnus.com)
11897 * ch-parse.y: Major change to remove or at least identify
11898 parser ambiguities. One result: We now allow actions that
11899 start with '(', as required by teh Blue Book. This does break
11900 some things; look for FIXME for things that need work.
11901 * ch-typeck.c (chill_expand_case_expr): We need an extra
11902 level of looping to (in the future) support <case label
11903 specification>s with more than one <case label list>.

11927 on arrays of BOOLs.
11929 Mon Dec 7 08:55:20 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11931 * ch-actions.c (lang_init): Set LINENO to 1 at beginning to
11932 indicate we are done with initialization.
11934 * ch-decl.c (do_decls): Set TREE_PUBLIC if we are doing a
11936 (start_chill_function): Ditto.
11938 * ch-lex.c (convert_bitstring): Set TREE_CONSTANT.
11939 (compiler_directive): Don't confuse compiler directives with
11940 equality comparison operators.
11942 * ch-parse.y: Clear CURRENT_LOCNAMELIST after calling do_decls.

11955 * tree.def: Move CARD_EXPR and SET_LE_EXPR back down with the other
11956 Pascal-required ones, since C++ no longer needs them. When
11957 Chill's public, a comment can be added to the effect that
11958 SET_LE_EXPR is also used by Chill.
11960 Fri Dec 4 12:05:01 1992 Bill Cox (bill@cygnus.com)
11962 * Restore CARD_EXPR and SET_LE_EXPR to tree.def.

12001 (push_newmode,push_synmode): Call `fixup_unknown_type' when we
12002 see a declaration that uses `unknown_type_node'. FIXME.
12004 * ch-grant.c (decode_constant): New function.
12005 (decode_decl): Call `decode_constant' for CONST_DECLs.
12007 * ch-lex.l (char action): Use ridpointers instead of
12008 lookup_name to get "char"'s declaration.
12010 * ch-parse.y: Call `build_lang_decl' instead of `build_decl'
12011 when we need to build a TYPE_DECL.
12013 Tue Dec 2 09:44:05 1992 Bill Cox (bill@cygnus.com)
12015 * ch-typeck.c: clean up a gcc warning with a forward
12016 declaration of build_string_type.
12018 Tue Dec 1 16:51:05 1992 Bill Cox (bill@cygnus.com)
12020 * ch-actions.c: completely remove those builtin calls
12021 that are duplicated in c-decl.c
12023 Tue Dec 1 16:38:51 1992 Fred Fish (fnf@cygnus.com)
12025 * ch-actions.c (lang_init): Ifdef out initializations for
12026 __builtin_abs and __builtin_fabs, since they are duplicates of
12027 initializations in c-decl.c, and trigger spurious warnings.
12029 Tue Dec 1 16:35:18 1992 Bill Cox (bill@cygnus.com)
12031 * ch-parse.y: make size() work with a typename argument.

12040 * ch-lex.l: fix char-type
12042 Tue Dec 1 11:10:56 1992 Bill Cox (bill@cygnus.com)
12044 * ch-parse.y, ch-actions: added parsing and processing
12045 for upper, lower, and length built-ins.
12047 Tue Dec 1 09:40:49 1992 Fred Fish (fnf@cygnus.com)
12049 * dwarf.h (LANG_CHILL): Add as GNU extension.
12050 * dwarfout.c (output_compile_unit_die): Test language_string and
12051 set LANG_CHILL if appropriate.
12052 * ch-parse.y (language_string): New for chill.
12053 * chillrt: Renamed directory chill to chillrt.
12054 * chill: Renamed chillsh to chill.
12055 * Makefile.in: Adjust for renamings.
12056 * chillrt/Makefile: Adjust for directory renaming.
12058 Mon Nov 30 17:35:33 1992 Fred Fish (fnf@cygnus.com)
12060 * chillsh: New script frontend (ala g++), installed as "chill".
12061 Can't be called "chill.sh" because make tries to cat it into the
12062 "chill" directory. Can't be called just "chill" cause that's
12063 already there as a directory.
12064 * Makefile.in: Add rules to install chillsh as "chill".
12065 * chill/libchill.c: Temporarily ifdef out stuff that wants
12066 to conflict with i486/SVR4 runtime or wants to pull in librmt.a,
12067 which itself causes linkage to fail.
12069 Mon Nov 30 16:28:19 1992 Bill Cox (bill@cygnus.com)
12071 * ch-lex.l: added keywords for TRUNC, ROUND, FLOAT, LFLOAT
12072 conversion routines.
12073 * ch-parse.y: added %tokens for TRUNC, ROUND, FLOAT, LFLOAT.
12074 Added production for SIZE(expr).
12075 * ch-actions.c: Add semantic routine chill_sizeof ().
12077 Mon Nov 30 16:20:40 1992 Per Bothner (bothner@cygnus.com)
12079 * ch-lex.l, ch-parse.y: Translate token PFEIL into English ARROW.
12080 * ch-parse.y (op6): Remove handling of string repetition operator,
12081 until we can figure out a way to parse it correctly.
12082 * ch-parse.y (optmodename): New non-terminal.
12083 * ch-parse.y (tuple): Merge the two variants using optmodename.
12084 * ch-parse.y (location): Add semantic actions for
12085 dereferencing operator ->.
12087 Mon Nov 30 08:01:29 1992 Bill Cox (bill@cygnus.com)
12089 * ch-actions.c: removed compile warning, better code for abs.
12091 * ch-parse.y: add productions for builtin functions succ, pred,
12092 abs, and size. Add %tokens also. Sort %tokens alphabetically.
12094 * ch-lex.l: add parsing for builtin function names, such as abs,
12095 pred, succ, etc. Put flex -a option into Makefile.in, so we can
12096 clean up the lexer soon.
12098 Tue Nov 24 14:18:48 1992 Per Bothner (bothner@rtl.cygnus.com)
12100 * ch-typeck.c (chill_handle_case_label, chill_handle_case_default):
12101 New functions, for code common to CASE actions and expressions.
12102 * chill.y: Replace some code by calls to chill_handle_case_label
12103 and chill_handle_case_default.
12104 * ch-typeck.c (chill_expand_case_expr): Add semantics.
12106 * tree.c: Change doing_chill_thang from extern to common.
12108 Mon Nov 23 18:34:22 1992 Per Bothner (bothner@rtl.cygnus.com)
12110 * ch-tree.def: New CASE_EXPR type, for case expressions.
12111 * ch-expr.c (chill_expand_expr): Hook for CASE_EXPR.
12112 * ch-typeck.c (chill_expand_case_expr): New function.
12113 Placeholder to implement case expressions.
12114 * ch-typeck.c (chill_expand_result, chill_expand_return):
12115 Handle mode-unspecified tuples and case expressions in
12116 the context of RETURN and RESULT actions.
12117 * chill.y (assignaction): Handle case expressions in the
12118 context of the RHS of an assignment action.
12119 * chill.y (caseaction): Remove spurious duplicate OF in grammar.
12120 * chill.y: Handle labeled structure tuples.
12121 * chill.y: New rules to parse CASE expressions.
12122 * tree.c (build_function_types): Allow Chill functions
12123 to return arrays and functions.
12125 Wed Nov 18 13:50:28 1992 Per Bothner (bothner@rtl.cygnus.com)
12127 * ch-typeck.c (chill_expand_tuple): New function. Expand a
12128 tuple (constructor) given an expected (context) type.
12129 * chill.y: Implement 'LHS := TUPLE' using expand_chill_tuple,
12130 using the mode of the LHS and the expected type of the TUPLE.
12131 * chill.y: Implement initialization.
12132 * chill.y: Fix some syntax bugs (forbidlist must be surrounded
12133 by parentheses), and remove or note ambiguities.
12134 * chill.y: Started converting layout style to be like c-parse.in.
12135 * chill.y: Implement IF expressions.
12136 * chill.y: Added syntax rules for tuples. Labelled and unlabelled
12137 array tuples should now work (in some contexts).
12138 * ch-actions.c: Initialize doing_chill_thang to 1.
12139 * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
12140 initializer, to make pushdecl and finish_decl work.
12141 * c-decl.c (convert_for_assignment): If Chill, don't convert
12142 function and arrays into pointers. (Maybe functions should
12143 still be converted?)
12144 * c-typeck.c (grokdeclarator): Allow functions in Chill
12145 to return arrays and functions.
12147 Mon Nov 16 15:40:47 1992 Per Bothner (bothner@rtl.cygnus.com)
12149 * chill.y (exprlist_get_single): New function, used when
12151 * chill.y: Re-did parsing of tuples to remove ambiguities.
12154 Tue Nov 10 16:30:55 1992 Per Bothner (bothner@rtl.cygnus.com)
12156 * ch-typeck.c (chill_expand_result); Set TREE_SIDE_EFEFCTS
12157 flags on assignment to result.
12158 * ch-typeck.c (build_chill_array_ref): Subtract lower
12159 bound of domain if non-zero. Preliminary hook for range checking.
12160 * ch-tree.h, chill.l: Combine variables range_check and
12161 range_check_disabled into global variable range_checking.
12162 * ch-tree.h: Better definitions of CH_CLASS_IS_VALUE
12163 CH_CLASS_IS_DERIVED.
