3441 Wed Aug 17 05:52:44 1994 Wilfried Moser (moser@rtl.cygnus.com)
3443 * Make-lang.in: Change version of GNUCHILL compiler to 1.4.1.
3444 * expr.c (build_chill_length): Enable LENGTH built-in to process
3445 Buffers and Events too (Z.200/1992).
3446 * lex.l (yywrap): Always set yyin to finput and/or grt_in. On
3447 a linux system the previous version was not able to run.
3448 * tasking.c: Correct processing of infinite buffer- and event-length
3449 to avoid RANGEFAIL warning.
3451 Thu Aug 11 11:46:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3453 * parse.c (parse_if_expression_body): Don't call the C-specific
3454 build_conditional_expr. Just do build_nt (COND_EXPR, ...).
3455 * convert.c (convert): Convert a COND_EXPR by converting
3458 * convert.c (convert): Don't call convert before
3459 convert_to_reference. It's apt to do weird and unneedful things.
3460 * convert.c (convert): If the expression is varying, just call
3461 varying_to_slice, which simplifies quite a bit.
3463 * ch-tree.h (varying_to_slice): Add prototype.
3464 * typeck.c (varying_to_slice): Remove prototype.
3466 * satisfy.c (satisfy): Move case PAREN_EXPR from type 'e'
3469 * except.c (emit_setup_handler): Temporarily reset the
3470 maximum_field_alignment to zero so the compiler's exception
3471 data structures can be compatible with the run-time system,
3472 even when we're compiling with -fpack.
3474 * expr.c (compare_records): Call saved_if_needed on operands.
3476 * expr.c (build_set_expr case NE_EXPR): Don't use __nepowerset
3477 which has been reimplemented to just call __eqpowerset and
3478 invert the result. Inline this new implementation by
3479 handling as EQ_EXPR, and inverting the result.
3480 * decl.c (init_decl_processing): Don't define unused __eqpowerset.
3482 * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
3483 type boolean_type_node, not void_type_node. (Fixing this
3484 avoids a crash in the back-end.)
3486 * grant.c (decode_constant): In a CALL_EXPR, if the argument
3487 list is not a TREE_LIST (as in string repetiation), don't
3490 Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3492 * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
3493 CONST_DECL is from a SET definition. (This is safer than
3494 checking that the type is ENUMERAL_TYPE, because synonym
3495 definitions may have a NULL TREE_TYPE.)
3496 Also, if we have duplicate enums whose types are identical,
3498 * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
3499 an extra 'quiet' parameter, which is true if we're called from
3500 bind_sub_modules. (In that case an error message about duplicated
3501 decls would be repeated later, so suppress it.)
3503 * parse.c (stmt_count): Removed, not used.
3504 (INIT_ACTION): Call emit_line_note only if !ignoring.
3505 (parse_begin_end_block): Do INIT_ACTION even if ignoring.
3507 Fri Aug 5 12:39:11 1994 Per Bothner (bothner@kalessin.cygnus.com)
3509 * parse.c (parse_untyped_expr): Add missing semi-colon.
3511 Thu Aug 4 17:40:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
3513 * parse.c (parse_untyped_expr): Fix various problem for the
3514 case that we see a '(': Add missing 'case' keyword.
3515 Only recurse if '(' is followed by 'if', 'case' or '[',
3516 and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
3518 * parse.c (parse_send_action): Remove extra nreverse.
3520 Thu Jul 28 04:00:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3522 * expr.c (build_allocate_global_memory_call, build_allocate_memory_call):
3525 Tue Jul 26 22:48:15 1994 Michael Tiemann (tiemann@blues.cygnus.com)
3527 * parse.c (parse_untyped_expr): Added missing "case" before LPRN.
3528 Added a missing call to `require' as well.
3530 Tue Jul 19 10:30:12 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3532 * lex.l (yywrap): Define as yywrap_chill to avoid conflicts with
3533 the extern declaration in the flex skeleton.
3535 Mon Jul 18 23:06:04 1994 Per Bothner (bothner@kalessin.cygnus.com)
3537 * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
3538 Check the type of the instance expr using CH_COMPATIBLE,
3539 and not just == instance_type_node. (This allows
3540 the expression to have mode READ INSTANCE).
3541 * tasking.c (build_instance_type): Give instance_type_node
3542 a non-null novelty (i.e. different from a struct).
3543 * tasking.c (build_receive_case_start, build_delay_case_start):
3544 Check that for a location using CH_LOCATION_P.
3546 Mon Jul 18 13:22:23 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
3548 * expr.c (finish_chill_unary_op): Use TREE_SET_CODE not TREE_CODE
3549 to modify a tree code.
3551 Mon Jul 18 11:24:57 1994 Bill Cox (bill@rtl.cygnus.com)
3553 * convert.c (digest_structure_tuple): Fix thinko in TREE_CODE
3556 Mon Jul 18 05:40:15 1994 Doug Evans (dje@canuck.cygnus.com)
3558 * decl.c (warn_bad_function_cast): Define so cc1chill will link.
3560 Thu Jul 14 18:37:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3562 * parse.c (parse_send_action): Do tree_cons *before* checking
3565 Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3567 * convert.c (digest_structure_tuple): Don't use convert to
3568 coerce initial value, use chill_convert_for_assignment instead.
3569 (Thus we also get range_checking.)
3571 * expr.c (build_chill_card): Use force_addr_of instead of
3572 build_chill_addr_expr.
3574 * loop.c (build_temporary_variable): Stylistic tweak.
3575 * loop.c (maybe_make_for_temp): Initialize temp using
3576 explicitly, not using assignment. Avoids a problem if
3577 the expression is read-only.
3578 * typeck.c (smash_dummy_type): Always used the saved TYPE_NAME
3579 and CH_NOVELTY_FLAG.
3581 Wed Jul 6 20:12:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3583 * expr.c, ch-tree.h (finish_chill_unary_op): New function,
3584 based on code ripped out of build_chill_unary_op.
3585 (build_chill_unary_op): Call finish_chill_unary_op unless pass==1.
3586 * satisfy.c (satisfy): Call finish_chill_unary_op when needed.
3588 Mon Jun 27 11:29:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3590 * tree.c (save_if_needed), ch-tree.h: New function.
3591 * typeck.c (build_chill_slice_with_range,
3592 build_chill_slice_with_length): Call save_if_neeed on array arg.
3593 * expr.c (varying_to_slice): Re-write to use save_if_needed.
3595 * typeck.c (extract_constant_from_buffer): Handle BOOLEAN_TYPE.
3597 Mon Jun 27 01:11:10 1994 Wilfried Moser (moser@rtl.cygnus.com)
3599 * inout.c (build_chill_io_list_type): Change layout of __tmp_WIO_list
3600 that it is always the same, regardless if compiled with -fpack
3603 Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3605 * lex.l (yywrap): Kludge to work around mis-synchronization
3606 between lexer (which read ahead) and parser: Don't emit
3607 (left-over) uze_seizefile directives at the end of file.
3609 * typeck.c (build_chill_array_ref): Allow the derived
3610 array indexing syntax for arrays of bit strings.
3611 Add a comment explaining why.
3613 * typeck.c, ch-tree.h (string_assignment_condition): Change
3614 the interface. Return a boolean expression (which can be
3615 used in a conditional at run-time); never expand anything.
3617 * actions.c (chill_convert_for_assignment): Check
3618 string_assignment_condition here, rather than in callers.
3619 * actions.c (chill_expand_assignment): Don't need to check
3620 string_assignment_condition here.
3621 * expr.c (build_chill_function_call): Likewise.
3622 * satisfy.c (safe_satisfy_decl): Update accordingly.
3623 * decl.c (do_decl): Simplify testing and conversion by
3624 deferring everything to chill_convert_for_assignment.
3626 * parse.c: Combine the two variables 'ignore_exprs' and
3627 'ignore_actions' into one variable called 'ignoring'.
3628 * ch-tree.h: Add 'extern int ignoring'.
3629 * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
3630 Rename ignore_actions and ignore_exprs to ignoring.
3631 Remove unneeded extern declarations.
3632 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3633 build_chill_arrow_expr, build_generalized_call, build_delay_action,
3634 build_buffer_type, build_event_type): I changed my mind. It is
3635 cleaner to check for 'ignoring' in the parser, rather than here.
3636 * parse.c (parse_action, parse_primval, parse_opt_mode):
3637 Therefore we must check for ignoring here.
3638 * parse.c (parse_loc_declaration): Set ignoring in pass 2
3639 when parsing the mode.
3641 * tasking.c (generate_tasking_code_variable): Do arithmetic
3642 on signal_code etc using unsigned rather than signed shorts.
3644 * grant.c (static char* current_grant_modename): Removed.
3645 * grant.c (decode_decl case CONST_DECL): Remove error message.
3647 * Make-lang.in (CHILL_SRCS): Add $(srcdir)/ch/parse.c.
3648 * Makefile.in: Fix dependencies for parse.o.
3649 Remove some duplicate dependencies for $(TREE_H).
3651 Mon Jun 13 14:25:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3653 * typeck.c (build_chill_cast): Allow a value cast between
3654 non-discrete object of the same size, but with a pedwarn.
3655 * typeck.c (bit_string_assignment_condition,
3656 char_string_assignment_condition): Merge near-duplicate functions
3657 and place the code in string_assignment_condition.
3659 * decl.c (parm_flag, declare_parm_level, in_param_level_p):
3661 * decl.c (start_chill_function, finish_chill_function): Make
3662 parameter level have same nesting level as body, as required by Z200.
3663 * decl.c (switch_to_pass_2): Always exit if an error has been found.
3664 * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
3665 generated from GRANT ALL.
3666 * decl.c (lookup_name_for_seizing): Don't seize from
3667 the nesting level of builtins (predefined objects).
3668 * decl.c (lookup_name_for_seizing): Make more robust on error.
3670 * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
3671 be 'RESULT' (or 'result'). This makes it more accessible from gdb.
3672 Also, use do_decl to declare it, so that debugging symbols are
3673 generated. And, re-arrange so that actions that need to
3674 be done both passes (such as push_levels) use the same code.
3676 * parse.c (get_type_of): If ignore_exprs, don't lookup name.
3677 * parse.c (end_function): Fix poplevel params.
3678 * parse.c (expect): Don't read forwards on an error.
3679 * parse.c (parse_field): Don't define two tag_list locals!
3680 * parse.c (parse_pass_1_2): Better error message.
3682 * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
3683 parse_opt_mode, rather than vice versa. If parse_opt_mode
3684 returns NULL_EXPR, then parse_mode gives an error.
3685 Change parse_opt_mode (and any functions it calls) to only
3686 return NULL_TREE if there is no mode (even on ignore_exprs).
3687 (parse_set_mode, parse_structure_mode, parse_procedure_mode):
3688 Never return NULL_EXPR.
3689 * tasking.c (build_buffer_type, build_event_type): Return
3690 void_type_node instead of NULL_EXPR if ignore_exprs is true.
3692 * parse.c (parse_synonym_definition): Call parse_untyped_expr
3693 only if we have a mode.
3694 * parse.c (parse_send_action): Parse list of untyped_expr's,
3695 rather than a list of (typed) expressions.
3696 * parse.c (parse_primval): Emit error if '[' seen without
3697 preceding mode name. (If this is to be allowed, call
3698 parse_untyped_expr instead.)
3700 * parse.c (parse_array_index): Renamed to ...
3701 (parse_index_mode): ... to match Z200 terminology.
3702 Re-write to resolve some of the nastier ambiguities,
3703 and allow things like ' CHAR(10) : CHAR(20) '.
3705 * parse.c (parse_tuple_element): Change interface to return
3706 reversed list, so don't call nreverse.
3707 * parse.c (parse_tuple): No longer nreverse element list here.
3708 * parse.c (parse_opt_element_list): Do nreverse here instead.
3709 * parse.c (parse_case_label_list): Call nreverse at end.
3711 Fri Jun 10 15:36:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
3713 * typeck.c (chill_similar): Remove bogus "else".
3715 Wed Jun 8 00:01:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
3717 * ch-tree.h (TYPE_ARRAY_MAX_SIZE): New macro (and comment)
3718 to make it clearer that we are using TYPE_MAX_VALUE in a special way.
3719 * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
3720 * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
3721 * convert.c (convert): When converting a fixed string/array
3722 to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
3723 of (the type of) the padding.
3724 * convert.c (convert): If the concatenation is non-constant, use
3725 the low-level 'build' to set the type of the result (which is usually
3726 a fixed-size array) rather than depend on build_chill_binary_op
3727 to figure it out (it's unable to simplify the size to a constant).
3729 Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
3731 * lang.c (lang_decode_option): Let -fspecial_UC imply
3732 -fno-ignore-case without requiring it explicitly.
3733 * lang.c (lang_decode_option): Support (experimentally)
3734 the -fpack and -fno-pack flags.
3736 Thu Jun 2 20:49:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3738 * configure: Add support for --program-prefix and --program-suffix.
3740 Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3742 * convert.c (digest_constructor): Check that initial value
3743 is compatible with element mode before calling convert.
3744 * typeck.c (chill_compatible): A string mode is not compatible
3745 with an untyped constructor.
3746 * decl.c (do_decl): Clean up error messages. Use error_with_decl.
3748 * ch-tree.h: Fix inconsistencies: bool_true_node ->
3749 boolean_true_node, and bool_false_node -> boolean_false_node.
3750 * typeck.c (valid_array_index_): Minor simplification.
3752 Tue May 31 04:33:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3754 * inout.c (build_chill_writetext): Add correct processing
3755 of POWERSET RANGE (setmode).
3757 * lex.l (same_file): Add searching for file(s) in
3760 Fri May 27 14:22:42 1994 Per Bothner (bothner@kalessin.cygnus.com)
3762 * Make-lang.c (CHILL.mostlyclean, CHILL.distdir): Don't list
3763 yacc/bison output files, since the grammer is no longer in yacc.
3764 * config-lang.in (diff_excludes): Likewise.
3766 Thu May 26 16:38:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3768 * gperf, hash.h, lex.l, parse.h: Rename PROCESS_TYPE token
3769 (in some files spelled PROCESS_TYPE_ to avoid clashes
3770 with the PROCESS_TYPE tree_code) to PROCESS_TYPE_TOKEN.
3772 Thu May 26 02:18:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3774 * timing.c (build_cycle_start): Change call to __define_timeout.
3775 * decl.c (init_decl_processing): Change definitions of
3776 __define_timeout and __wait_timeout.
3778 Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
3780 Replace yacc-based parser with a recursive-decent parser.
3781 (This may seem backwards, but Chill [like C++] is not a
3782 language that is remotely LALR(1). Using a R-D parser
3783 allows us to use look-ahead and to back-up to resolve the
3784 difficult ambiguities.)
3786 * parse.c, parse.h: New files, containing new r-d parser.
3787 * Makefile.in: Update accordingly.
3788 * actions.c (chill_convert_for_assignment): Don't return
3789 NULL_EXPR if ignore_exprs is true. It simplifies the parser
3790 if we consistently reserve NULL_EXPR for a missing expression.
3791 * expr.c (build_chill_function_call): Likewise.
3793 * lex.l: Tweaks for new parser.
3794 * lex.l (prepare_paren_colon, paren_paren_colon_level,
3795 paren_level): Ugly hack no longer needed.
3797 * expr.c (build_chill_function_call): Cleanup.
3798 Call chill_convert_for_assignment to convert IN/INOUT
3799 paramaters on both input and output. For LOC parameters,
3800 give error if actual is a non-referable location.
3801 * actions.c (convert_for_assignment): Add new parameter (a
3802 "place" string used in error messages).
3803 * actions.c (adjust_parm_or_field): Removed.
3804 * actions.c (chill_expand_assignment): Take just a single LHS,
3805 and move support for multiple assignments to ...
3806 (expand_assignment_action): ... here. Some cleaning up.
3807 * timing.c (build_cycle_start): Adjust accordingly.
3808 * actions.c (expand_assignment_to_varying_array): Likewise.
3809 * tasking.c (many places): Ditto.
3810 * ch-tree.h: Fix declarations appropriately.
3812 * parse.c (parse_defining_occurrence_list): Return a single
3813 IDENTIFIER_NODE (instead of a singleton list) in the common
3814 case. Minor complication to save a minor amount of space.
3815 * decl.c (do_based_decls): Move guts of code into ...
3816 (do_based_decl): ... this new function.
3817 * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
3818 * decl.c (push_syndecl): Replace by ...
3819 (push_syndecl): ... (which only supports a single name).
3820 (push_modedef): Only handle a single name.
3821 * tasking.c (build_process_header, build_signal_struct_type):
3824 * expr.c (build_generalized_call): Handle string repetition.
3825 * expr.c (build_chill_repetition_op): Change interface.
3826 * grant.c (decode_constant): Allow parameter list to be
3827 a non-TREE_LIST. (Used for string repetition.)
3829 Wed May 25 11:28:48 1994 Per Bothner (bothner@kalessin.cygnus.com)
3831 * lex.l (make_identifier): Replaced by ...
3832 (read_identifier, handle_name): ... new functions.
3833 * lex.l: Parse an identifiers using read_identifier using
3834 read_identifier and handle_name, rather than having [f]lex
3835 do it. (One reason is that lex uses a fixed-size buffer.)
3837 * lex.l (read_directive, skip_directive): New functions.
3838 Use them to parse compiler-directives, instead of rather
3839 ugly and useless use of lexer start conditions.
3841 Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3843 * decl.c (unnamed_module_number): Renamed to ...
3844 (module_number): .. and make non-static.
3845 (push_module): Always increment module_number.
3846 * lex.l (yywrap): Print warning if no modules seen.
3848 * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
3849 decl to current_seizefile_name (which is unreliable).
3850 * grant.c (chill_grant): Set it here instead.
3852 * expr.c (fold_set_expr): Use int_size_in_bytes instead of
3853 TYPE_PRECISION (which is not defined for a SET_TYPE).
3855 Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
3857 Cleanup to remove need for variables in common storage.
3858 * decl.c: Remove unused use of current_obstack.
3859 * actions.c (maybe_chill_check_decl): Remove unused function.
3860 * actions.h, lang.c: Remove uses of doing_chill_thang.
3861 * ch-tree.h (void_list_node): Make extern (rather than common).
3862 * decl.c (void_list_node): Add definition.
3864 Thu May 19 06:54:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
3866 * configure (build): Build canon_host and canon_target
3867 to pass it to all subsequently generated Makefiles (needed
3868 for testsuite/execute in case of cross build).
3870 Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
3872 * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
3873 the input type, which loses with the no-longer-new 2-pass
3874 implementation, since the input "type" could be an IDENTIFIER_NODE.
3875 * grant.c (raw_decode_mode): Rename to decode_mode.
3877 Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3879 * typeck.c (chill_location): Neither a STRING_CST nor a
3880 CONSTRUCTOR is a location.
3881 * typeck.c (chill_root_mode): Convert a function to a
3882 pointer-to-function.
3883 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3884 build_chill_arrow_expr): If ignore_exprs, return operand
3885 rather than NULL_EXPR. This makes it easier for the parser to
3886 distinguish missing expressions.
3887 * expr.c (build_max_min): Convert the lower bound of a
3888 set to a long before calling run-time routine.
3889 * expr.c (build_chill_pred_or_succ): Use discrete_type_p
3890 to check the argument type.
3891 * expr.c (build_chill_arrow_expr): If argument is not a location,

3928 * parse.y (optsigdest): Force ignore_exprs to 0 while parsing

3939 * parse.y (optresultspec): Call build_chill_reference_type, rather
3940 than build_reference_type (which incorrectly sets TYPE_SIZE).
3941 * parse.y (range_or_mode): Rename to plain range, since it
3942 no longer matches modename.
3943 * actions.c (chill_handle_case_label_range): New function, with
3944 functionality moved out of chill_handle_case_label.
3945 * actions.c (chill_handle_case_label): Handle here the case that

3987 * parse.y (ioindexmode): Removed; use index_mode instead.
3988 * expr.c (build_generalized_call): If args is a RANGE_EXPR,
3989 we have either a slice or a range mode, depending on func.
3990 * parse.y (index_mode): If we got an 'expr', only allow a name,
3992 * parse.y (call): A slice with both end points can be a range
3993 mode, so defer handling to build_generalized_call (or index_mode).
3995 * typeck.c (build_chill_slice_with_length): Fix type-checking.
3996 * typeck.c (chill_novelty): Undo (part of) change of April 28:
3997 The novelty of a range mode is the novlety of the parent.

3999 if argument has non-nil novelty.
4001 * decl.c (global_bindings_p): Return -1 as true, for the sake
4002 of variable_size (in ../stor-layout.c).
4004 Fri Apr 29 13:42:43 1994 Per Bothner (bothner@kalessin.cygnus.com)
4006 * parse.y: Remove TYPENAME and modename. These are now plain
4007 NAMEs. Modify parsing actions appropriately.
4008 * expr.c (build_generalized_call): Handle the case that
4009 TREE_CODE (func) == TYPE_DECL (as in a cast).
4010 * lex.l (name_type_signal): Never return TYPENAME.
4011 * parse.y (get_type_of): If pass 1, just return the argument.
4013 * decl.c (do_decl): If an initializer has the wrong type,
4014 replace it by NULL_TREE, to avoid subsequent errors.

4060 * typeck.c (smash_dummy_type): Handle the special case of a
4061 NEWMODE of a range mode, as required by Z200, by creating a
4062 new parent mode with the new novelty (and casting the min
4063 and max of the range to teh new parent mode).
4064 * typeck.c (chill_novelty, chill_root_mode): Remove special
4065 kludges for of NEWMODE ranges.
4066 * expr.c (build_chill_lower_or_upper): New function, combining

4350 Wed Mar 23 13:34:18 1994 Bill Cox (bill@rtl.cygnus.com)
4352 * expr.c (build_generalized_call): Revert previous change.
4353 To do this correctly, we need a new parsing mechanism, and

4375 * configure: Generate better .gdbinit files.
4377 Tue Mar 22 11:59:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
4379 * actions.c (check_range): Don't emit dynamic checks
4380 if not current_function_decl.
4382 * parse.y (arrayindex): Allow expr (error is emitted
4383 at semantic level if not the NAME of a type).
4384 * typeck.c (build_chill_cast): Re-enable some casts.
4385 * satisfy.c (safe_satisfy_decl): Remove redundant CONST check.

4402 string assignment case.
4403 * expr.c (chill_expand_expr): Now that we're using build_chill_function_call,
4404 the actual parameters need to be converted to the unsigned long
4405 type explicitly. Do that.
4406 * satisfy.c (safe_satisfy_decl): Correct range-checking code.
4408 Mon Mar 21 16:25:07 1994 Bill Cox (bill@rtl.cygnus.com)
4410 * Makefile.in: Correct prediction of grammar conflicts.
4411 * actions.c(check_range): Fix reference to NULL_TREE pointer.

4414 * satisfy.c (safe_satisfy_decl): Add range-check for a SYN's value.
4416 Mon Mar 21 13:29:23 1994 Per Bothner (bothner@kalessin.cygnus.com)
4418 * typeck.c (layout_chill_range_type): Instead of tree_int_cst_lt
4419 use compare_int_csts (which is more robust when signedness differs).

4423 * expr.c (chill_expand_expr): Code to expand SET_IN_EXPR,
4424 moved from expand_expr in ../expr.c. Also add some extra
4425 conversions (because we're now using build_chill_function-call).
4426 * actions.c, decl.c, expr.c, grant.c, parse.y, typeck.c:
4427 Use SET_IN_EXPR in place of IN_EXPR.
4429 * expr.c (build_compare_discrete_expr), ch-tree.h: New function,
4430 with code moved from build_compare_expr.
4431 * expr.c (build_compare_expr): Re-enable compatibility test.
4433 Mon Mar 21 11:02:33 1994 Bill Cox (bill@rtl.cygnus.com)

4445 convert, to get the range-checking.
4446 * expr.c (build_chill_pred_or_succ): Fix up rangefail code.
4447 Generate a compile-time message if possible.
4448 (build_compare_expr): Comment out compatibility test - should
4449 not be needed in here. Fix a couple of typos. Add some types
4450 to some build calls.
4452 Sun Mar 20 11:48:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
4454 * decl.c (init_decl_processing): Clean up parameter type
4455 list for __setbitpowerset,
4457 * typeck.c (chill_compatible_classes): Allow the M-reference
4458 to be compatible with the N-value class, with suitable M and N.
4459 * typeck.c (build_chill_slice): Don't smash a void TREE_TYPE.
4460 (We don't need to, and it causes confusion.)
4462 * expr.c (build_compare_expr): Fix thinko. Add save_exprs.
4464 * expr.c (build_compare_expr): Fix a transcription bug
4465 (for converting NULL INSTANCEs). Also #include convert.h.
4467 * expr.c (compare_int_csts): New. Compare INTEGER_CSTs.
4468 Works even if their types have different TREE_UNSIGNED.
4469 * expr.c (finish_chill_binary_op): Moved code dealing with
4470 the comparison operators from here ...
4471 * expr.c (build_compare_expr): ... to new function here.
4472 Also, for discrete types, tries to Do The Right Thing, even for
4473 differing values of TYPE_PRECISION and TREE_UNSIGNED.
4475 * ch-tree.h: Declare new functions.
4476 * typeck.c (valid_array_index_p): Various cleanups,
4477 including using new build_parse_expr.
4478 * parse.y: Use new build_compare_expr.
4480 * inout.c (build_chill_writetext): Handle REFERENCE_TYPE args.
4482 Sun Mar 20 08:54:27 1994 Bill Cox (bill@rtl.cygnus.com)

4485 Call build_chill_array_ref to get index checking.
4486 (chill_convert_for_assignment): Delete unused errstr

4494 to get runtime index checking.
4495 * expr.c (build_chill_pred_or_succ): Fix cond tree
4496 to have consistent operand types.
4497 * typeck.c (valid_array_index_p): Change interface to pass
4498 validity conditions back on caller's TREE_LIST. We
4499 cannot link the conditions to anything which a
4500 layout_type routine will expand, since that will occur
4501 before the exception handler is set up.
4502 Change calls to valid_array_index_p also.
4504 Fri Mar 18 14:40:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
4506 * actions.c, except.c, loop.c, tasking.c: Call
4507 build_chill_function_call instead of the C-specific
4508 build_function_call.
4509 * except.c (initialize_exceptions): Fix parmtype of __builtin_setjmp.
4510 * loop.c (top_loop_end_check): Coerce library function arg.
4511 * convert.c, expr.c: Re-write to avoid calls to C-specific
4512 function build_unary_op (e.g. by calling build1 directly).
4514 * typeck.c (chill_equivalent): Change to force failure
4515 for non-matching integral types (even if not ranges).
4517 * typeck.c, ch-tree.h (build_chill_slice): Make non-static.
4518 * expr.c (varying_to_slice): Call build_chill_slice (and not
4519 build_chill_slice_with_length, which does bunches of range
4520 checking and does not allow the length to be zero).
4521 * convert.c (convert): Fix off-by-one error.
4522 * actions.c (chill_expand_array_assignment): Minor cleaning up.
4524 Fri Mar 18 00:12:48 1994 Per Bothner (bothner@deneb.cygnus.com)
4526 * decl.c (init_decl_processing): __lepowerset and __ltpowerset
4527 take *two* pointer parameters, not one.
4528 * satisfy.c (satisfy): Only call the appropriate layout routine
4529 if TYPE_SIZE is 0 (i.e. type hasn't already been laid out).
4530 * typeck.c (build_chill_slice_with_length): Fix Bill's previous fix.
4532 Thu Mar 17 17:29:43 1994 Bill Cox (bill@rtl.cygnus.com)
4534 * expr.c (build_chill_function_call): Give function call the correct
4536 * typeck.c (build_chill_slice_with_length): Restore dynamic range
4537 checking, so it doesn't obscure the CONSTANTness of the length.
4539 Wed Mar 16 17:23:31 1994 Per Bothner (bothner@kalessin.cygnus.com)
4541 * typeck.c (build_chill_slice), expr.c (chill_expand_expr
4542 [case CONCAT_EXPR]): Remove kludge setting slice size upper bound
4543 in TYPE_LANG_SPECIFIC, and restore kludge setting it in MAX_VALUE.
4544 * typeck.c (build_chill_slice): Use TYPE_MAX_VALUE of
4545 array_type if needed for size upper bound of slice_type.
4546 * expr.c (build_concat_expr): Improve calculation of size upper bound.
4548 * typeck.c (valid_array_index_p): Check compatibility using
4550 * typeck.c (build_chill_slice_with_length); For now revert
4551 calling valid_array_index_p on length. (It makes it harder
4552 to realize when the slice is constant length.)
4553 * expr.c (build_chill_indirect_expr): Minor tweak. (This
4554 seems to work around a weird C compiler bug. ??)
4556 * expr.c (build_chill_function_call): Cleanup so it doesn't
4557 call build_function_call (in c-typeck.c).
4558 * typeck.c, expr.c: Use build_chill_function_call instead of
4559 build_function_call (in c-typeck.c).
4561 * parse.y (discrete_mode): Move some of the rules from
4562 non_array_mode into new non-terminal.
4563 (arrayindex): Use discrete_mode (with NAME and TYPENAME) to
4564 avoid some misparses.
4565 * ch-tree.h (SLICE_PTR, SLICE_LENGTH): Removed; unused.
4566 * convert.c (digest_structure_tuple): Add missing parameter.
4567 * decl.c (comptypes): Remove unused prototype.
4568 * decl.c (build_chill_function_type): Handle NULL return_type
4569 correctly (convert to void_type_node).
4570 * decl.c (init_decl_processing): layout boolean_type_node *after*
4571 we've set it's TYPE_MIN_VALUE and TYPE_MAX_VALUE.
4573 Wed Mar 16 16:08:22 1994 Bill Cox (bill@rtl.cygnus.com)

4576 * convert.c (convert): Correct calculation of padding length.
4577 * decl.c (grok_chill_fixedfields): Move ignore_exprs test to
4578 parse.y where it belongs. This permits the removal of a kludge
4579 in make_process_struct.
4580 * lex.l, parse.y: Call to_global_level for several errors. Add
4581 code to output error in only one pass.
4582 * tasking.c (make_process_struct): Delete kludge inserted on

4589 (build_rts_call): Ifdef it out - never used.
4590 (expand_varying_length_assignment): call valid_array_index_p.
4591 rather than validate_varying_array_ref.
4592 * ch-tree.h: Fix prototype for valid_array_index_p.
4593 * expr.c (chill_expand_expr): Call build_chill_array_ref to get
4595 (build_hill_lower, build_chill_upper): Return value now inherits
4596 the novelty of the input parameter.
4597 (varying_to_slice): Use CH_NOVELTY macro rather than calling
4598 chill_novelty directly.
4599 * grant.c (newstring): Make len unsigned and cast xmalloc parameter
4601 (print_integer_type): Pass string value as APPEND's second parameter.
4602 (decode_decl): Pass a boolean expression as print_proc_tail's
4604 (chill_finish_module_code): Make xmalloc's parameter unsigned.
4605 * lex.l: Pass sizes to xmalloc as unsigned ints. Pass second
4606 parameter to in_word_set as unsigned.
4607 * loop.c (build_loop_start): Check top_loop_end_check return value.
4608 * parse.y: Add casts to int for third do_decls parameter, fifth
4609 build_loop_iterator parameter, etc.
4610 * tasking.c (build_receive_case_end): Chack cond_stack before popping.
4611 * typeck.c (validate_varying_array_ref, chill_max_vary_array_index,
4612 valid_array_index): Delete them. They're now unused.
4613 (valid_array_index_p): Add function, call it everywhere that an
4614 array index is checked.
4615 (build_chill_slice): Restore old functionality where varying_to_slice
4616 is called to handle slices of varying arrays, rather than handling
4618 (build_chill_slice_with_range, build_chill_slice_with_length):
4619 Check range limits for TREE_CONST before calling tree_int_cst_lt.
4620 Delete now-obsolete checks of constant indices.
4622 Mon Mar 14 17:26:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4624 * parse.y (modeless_expr): New rule to allow ([...]) and (if...)
4625 to count as untyped_exprs. (This is not really permitted by the
4626 Blue Book, but has been requested by customers.)
4628 Thu Mar 10 10:11:02 1994 Bill Cox (bill@rtl.cygnus.com)
4630 * chill.texi: Document new command-line options.
4631 * expr.c (build_chill_num): Set unsigned parameter for
4632 type_for_size call correctly (unsigned for enums).
4633 * lang.c (lang_decode_option): Add command-line options to
4634 enable/disable runtime range-checking.
4635 * lex.l: Eat more whitespace.
4637 Thu Mar 10 09:41:37 1994 Bill Cox (bill@rtl.cygnus.com)
4639 * Makefile.in: Have rules to make parse.h, y.tab.c and other
4640 derived files. This allows the gcc/configure list of CHILL
4641 files machinery to work.
4642 * ch-tree.h (permanent_allocation): Add a parameter flag.
4643 * decl.c (finish_chill_function, finish_decl): Provide the
4644 new permanent_allocation flag.
4645 (poplevel): Return early, avoid a seg fault.
4646 * lex.l (NORMAL): Replace this whole state with the predefined
4647 INITIAL state. Force compilation state to global level after
4648 compiler directive error - prevents endless loop on error.
4649 (handle_use_seizefile_directive): Rewrite for readability.
4650 (chill_same_grant_file): Reindent.
4651 Generally handle whitespace differently.
4652 * regression.prpt: Print ten PR numbers per line. The report's
4655 Wed Mar 9 09:58:51 1994 Bill Cox (bill@rtl.cygnus.com)
4657 * decl.c (do_decl): Suppress the string-assignment-condition
4658 error - it was too often seen.
4659 * expr.c (expand_chill_expr): In CONCAT_EXPR, when argument has a
4660 runtime-changing length (as in a slice), get the parent array's
4661 allocation size from its type tree.
4662 * typeck.c (build_chill_slice): Support VARYING arrays. Pass
4663 parent array's static allocation size along in the slice type.

4675 to a call, so that SIZE () works on them.
4676 * tasking.c (make_process_struct): Force ignore_exprs non-zero
4677 when processing a SEIZEd PROCESS declaration. This prevents
4678 grox-fixed_fields from returning a NULL, and indirectly protects
4679 the chill_integer_type_node tree from corruption.
4681 Mon Mar 7 19:14:05 1994 Bill Cox (bill@rtl.cygnus.com)
4683 * Makefile.in: Use the 'all' target to build the runtime
4684 library and chillrt0.o.

4687 chill.regress.cron: Move to utils subdirectory.
4688 * expr.c (build_chill_function_call): Mark the INOUT
4689 temporary so it doesn't get optimized into a
4690 register. Fixes the execute/inout.ch bug.
4691 * typeck.c (layout_chill_range_type): Restrict it
4692 from complaining about an empty string type's
4695 Mon Mar 7 09:06:39 1994 Bill Cox (bill@rtl.cygnus.com)

4698 (OBJS, BC_OBJS): Delete unused variables.
4699 Add $(FLAGS_TO_PASS) to sub-make invocations.
4700 * ch_decomment.l, ch_makedepend, chill.patches, printf.c,
4701 tcov.awk, tcov.el, tcov.sh: Move to utils subdirectory.

4727 * inout.c (build_chill_writetext): Add handling of a REAL.
4728 * lex.l (INITIAL): Remove all code to discard 'header lines'.
4730 * parse.y (optheader): Remove - it's obsolete, as is the
4731 HEADEREL token definition.
4733 Fri Mar 4 09:41:18 1994 Bill Cox (bill@rtl.cygnus.com)
4735 * addtest: Fix suffix removal when suffix is .c186.
4736 * regression.sh: Allow for underscores on PR filenames.
4737 * typeck.c: Check in the rewrite mentioned earlier.
4739 Thu Mar 3 09:42:10 1994 Wilfried Moser (fs_moser at rcsw1h)
4741 * tasking.c (build_process_header): Build a debug structure

4755 range-checking code. Handle reference_type in convert call.
4756 (chill_expand_assignment): Produce an INDIRECT_REF for a

4794 * decl.c (push_extern_function, start_chill_function): New parameter
4795 to say whether return value is a LOC.

4832 Wed Feb 23 15:07:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4834 New cleaner solution to the following problem:
4835 Chill allows an action to be followed by an ON-handler.
4836 But we don't know if an action has a handler until we've parsed
4837 its end, yet we want to generate extra code to set up an
4838 exception handling contour only if needed. The old solution
4839 would generate code for the action into an rtl sequence, and then
4840 splice in the exception-setup code if we later found we needed it.
4841 This has a few problems (for example it confuses the management
4842 of stack temporaries), and is ugly. Now that the compiler is 2-pass
4843 we have a cleaner solution: In pass 1, we remember which actions
4844 were followed by ON-handlers. In pass 2, we use this information
4845 to generate appropriate code before an action.
4846 * except.c (push_handler, pop_handler): In pass 1, set up data
4847 structures (global_handler_list) to remember if an action has an
4848 ON-handler. In pass 2, digest this information, and setup
4850 * except.c, actions.h (pop_handler): Take an extra int arg.
4851 * except.c (emit_setup_handler): New function, with code (moved
4852 from chill_start_on) to emit code before an action that has a handler.
4853 * except.c (except_init_pass_2): New function.

4855 * parse.y (POP_UNUSED_ON_CONTEXT): Don't call pop_sequence.
4856 * parse.y: Invoke POP_UNUSED_ON_CONTEXT and POP_USED_ON_CONTEXT
4857 in pass 1 as well as pass 2.
4858 * parse.y (BEGIN ... END): Re-arrange logic to avoid block_stack
4859 (local to ../stmt.c) getting out of sync.
4860 * actions.c (push_action): Don't need to emit a NOP,
4861 now that we're no longer moving sequences around.
4862 * actions.c (push_action): Call push_handler even in pass one.

5495 now just loops over an argument list).
5496 * ch-actions.c, ch-expr.c, ch-inout.c: Use build_chill_array_ref_1
5497 instead of build_chill_array_ref where appropriate.
5498 * ch-actions.c, ch-expr.c, ch-typeck.c: Make operand 1 of a
5499 VARY_ARRAY_REF is a single index, not an index list.
5501 * ch-grant.c (__init_list): Renamed to _ch_init_list, to

5526 'struct ch_class class = chill_expr_class (expr);' to
5527 'struct ch_class class; class = chill_expr_class (expr);'
5528 to work around a bug in /usr/ucb/cc on SunOS4.
5530 Mon Jan 10 18:29:36 1994 Bill Cox (bill@rtl.cygnus.com)
5532 * ch-actions.c (chill_convert_for_assignment): Avoid seg fault.

5557 (convert): Use convert1 where appropriate.
5558 * ch-typeck.c: Formatting change.
5559 * ch-parse.y (build_chill_constructor): Fix thinko.
5561 * ch-expr.c (varying_to_slice): If array is not referable,
5562 call save_expr on it, rather than stabilize_reference.
5563 * ch-satisfy.c (safe_satify_decl, for CONST_DECL):
5564 Don't force value to value class if mode is not explicitly
5565 specified. Also, make sure convert etc is only done once.
5567 Sat Jan 8 16:37:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
5569 * ch-decl.c (build_chill_function_type): Don't call
5570 build_function_type, because it does hash canonicalization,
5571 which once in a while looses badly.

5573 for doing_chill_thang.
5575 * ch-tree.h (CH_DERIVED_FLAG): New flag.

5612 for unary set operations).
5614 * ch-expr.c (build_chill_array_expr): Take new argument FORCE. All
5615 callers changed. All callers changed.
5617 * ch-convert.c (digest_structure_tuple): Handle SELECTED_VARIANT
5618 being NULL_TREE until we've started walking the list of values via
5619 the loop over VARIANTs.
5621 * ch-parse.y (build_chill_constructor): If we see an IDENTIFIER_NODE,
5622 treat it as an enum value (and hence constant). Also, only set
5623 TREE_STATIC if the constructor is indeed constant.
5624 * c-typeck.c (chill_initializer_constant_valid_p): If we see a
5625 VAR_DECL, test the TREE_CONSTANT field of the DECL_INITIAL, don't
5626 recurse on the DECL_INITIAL.
5628 Wed Jan 5 01:24:50 1994 Bill Cox (bill@cygnus.com)
5630 * Makefile.in: Add CHILL to LANGUAGES variable.
5631 * ch-actions.c (check_range): Call build_binary_op instead of
5632 fold, build to get the common types chosen.

5641 negative loop step expression.
5642 * ch-tree.h: Add prototype.
5643 * ch-typeck.c (chill_max_vary_array_ref): Correct misunderstanding.
5644 A varying array's length field counts the NUMBER of active array
5645 array entries, not the byte-length of them.
5647 Tue Jan 4 17:57:39 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5649 * ch-decl.c (do_decl): Call `suspend_momenary' if the
5650 converted constructor must live on the permanent_obstack.
5651 * ch-convert.c (convert): When building a new SET_TYPE
5652 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.

5666 * ch-expr.c (build_chill_arrow_expr): Call `mark_addressable'.
5667 (build_chill_addr_expr): Take new argument ERRORMSG.
5668 All callers changed. Also, call `build_chill_addr_expr' where
5669 we used to call `build1 (ADDR_EXPR, ptr_type_node, ...)' since
5670 that now calls `mark_addressable' automagically.
5672 * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.
5673 This is needed because variables may appear in initialization
5674 statements, and their DECL_INITIALs are their values at
5675 initialization time.
5676 * ch-convert.c (digest_structure_tuple,digest_constructor): Changed
5677 to handle VAR_DECLs as initializers.
5679 * ch-convert.c (digest_structure_tuple): Copy elements of INITS so
5680 they aren't destroyed for later use.

5693 * ch-convert.c (digest_structure_tuple): Fix phasing problem in
5694 handling variant record initializers.
5695 (various places): Change `pop_init_level' calls to match
5696 `push_init_level' wrt implicit variable.
5698 * ch-typeck.c (build_chill_slice): Convert the dynamic max index to
5699 `integer_type_node' before using it in comparisons. FIXME: should
5700 this be done in `chill_max_vary_array_index' by default?
5702 Tue Jan 4 00:24:14 1994 Bill Cox (bill@cygnus.com)
5704 * ch-actions.c: Fix comments.
5705 * ch-parse.y: Define caseaction_flag.
5706 (caseaction): Create new caseaction_flag node at the start,
5707 then free it at the end. Check it before the ELSE code.

5709 place, generate a jump to the end of the case.
5710 * ch-typeck.c (build_chill_slice_with_length,
5711 build_chill_slice_with_range): Add lots of compile-time
5712 parameter range checking.
5714 Mon Jan 3 21:49:04 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5716 * ch-convert.c (digest_structure_tuple): Call `push_init_level' with
5717 implicit==0 everywhere, not 1.
5718 (digest_constructor): Ditto.
5720 * ch-actions.c (check_range): Permit limits to be NULL_TREE.
5721 Also, hack out some dead code.
5722 * ch-typeck.c (build_chill_slice): Check varying and non-varying
5723 slice constructs for range failures.
5724 (build_chill_slice_with_range): Reindented, but not changed.
5726 * ch-typeck.c (chill_max_vary_array_index): New function.
5727 * ch-expr.c (chill_expand_expr): Call it.
5729 * ch-decl.c (var_data_id, var_length_id): New variables.
5730 (init_decl_processing): Initialize them. All calls to
5731 get_identifier (VAR_LENGTH or VAR_DATA) are now replaced
5732 by references to these variables. This simplifies the code
5733 w/o obscuring anything.
5735 Mon Jan 3 21:24:44 1994 Bill Cox (bill@cygnus.com)
5737 * c-typeck.c: Fix comment.
5738 * ch-actions.c (chill_expand_assignment): Error assigning to

5742 parameters to setbitpowerset prototype.
5743 * ch-expr.c (build_chill_function_call): Error when passing a
5744 READonly location as a LOC or INOUT parameter.
5745 * ch-parse.y (mode): Correct code marking type as readonly.
5747 Mon Jan 3 19:03:55 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5749 * ch-actions.c (chill_expand_assignment): Disable code that defeats
5750 building varying array references.
5751 * ch-expr.c (chill_expand_expr): Add rangecheck code to
5752 VARY_ARRAY_REF case.
5753 * ch-typeck.c (build_chill_array_ref): Don't call an `expand_'
5754 function (in this case, `validate_varying_array_ref') when we're
5755 doing a `build_' operation.
5757 * ch-typeck.c (validate_varying_array_ref): Simplify interface
5758 since INDEX parameter can never meaningfully be an INDEXLIST.
5759 * ch-actions.c (expand_varying_length_assignment): Caller changed.
5761 Mon Jan 3 07:29:45 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5763 * ch-typeck.c (build_chill_cast): Set TREE_CONSTANT on NOP_EXPRs.

5765 if we need to build a CONSTRUCTOR for a SET_TYPE initializer.
5766 (digest_structure_tuple): If TREE_VALUE (VALUE) == NULL_TREE, don't
5767 call CH_COMPATIBLE or try to convert it to TREE_TYPE (FIELD). This
5768 can happen when constructors are output incrementally.
5769 * c-typeck.c (initializer_constant_valid_p): Handle SET_TYPEs.
5770 * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
5773 Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5775 * ch-convert (digest_structure_tuple): Handle SET_TYPEs. Also, call
5776 `convert' so we can handle INSTANCE types (and other anomolies)
5779 * ch-convert.c (digest_structure_tuple): Fixed variant
5780 structure initialization. Also fixed a typo (TYPE_NAME
5781 was being used on a FIELD_DECL instead of DECL_NAME).
5782 * c-typeck.c (initializer_constant_valid_p): Pass missing
5783 ENDTYPE argument on recursive call.
5784 (set_init_field): New function, needed by ch-convert.c change above.
5786 * ch-decl.c (layout_chill_variants): Added a FIXME next to an
5787 almost certain typo.
5789 * ch-expr.c (build_chill_arrow_expr): Call `build1' and set
5790 TREE_CONSTANT for static references.
5791 * ch-except.c (chill_start_on): Change calls to
5792 `build_unary_op' (which is C-specific) to `build_chill_arrow_expr'
5793 which has CHILL semantics.
5794 * ch-convert.c (convert): Ditto (albeit in some disabled code).
5796 Sat Jan 1 21:26:43 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5798 * ch-satisfy.c (safe_satisfy_decl): Reorder conditional test of
5799 TREE_CODE of DECL in case it's altered by actions in the switch.
5801 * ch-satisfy.c (satisfy): Undo abort added earlier on 1 Jan. CVS log
5802 mentions where to find code that triggers this case.
5804 * ch-actions.c (adjust_parm_or_field): Handle CONSTRUCTORS here as
5807 * ch-convert.c (digest_structure_tuple): Push to permanent_obstack if
5808 we're dealing with a CONSTRUCTOR that is TREE_PERMANENT.
5809 (digest_constructor): Ditto.
5811 Sat Jan 1 10:29:19 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5813 * ch-parse.y (handleraction,resultaction,assignaction,call): Modified
5814 so that CONSTRUCTORS are properly handled before being used.
5816 * ch-convert.c (chill_start_init): New function. All callers to
5817 `start_init' changed to call this function instead.
5818 (digest_struct_tuple): Defend against initialization machinery
5819 mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
5820 IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
5821 needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
5822 can be refered to throughout the compilation unit. Also remove an
5823 extraneous call to `process_init_element' erroneously added to the
5824 variant record sub-loop.
5825 (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
5826 CONSTRUCTORS of SET_TYPE.
5827 * ch-parse.y (build_chill_constructor): Refix typo. Also set
5828 TREE_STATIC if at top level.
5830 * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
5831 TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
5832 should have been called.
5834 * ch-convert.c (digest_struct_tuple): Restore code which tracks
5835 field initializations so that the compiler can deduce what variant
5836 initializations to assume.
5838 * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
5839 when we push into a scope that has a DECL with a CONSTRUCTOR as its
5842 * ch-parse.y (build_chill_constructor): Change the name of the
5843 parameter to something more meaningful. Fix typo. Also, handle case
5844 where element is an untyped CONSTRUCTOR.
5846 * ch-except.c (finish_handler_array): Set TREE_CONSTANT on
5847 constant ADDR_EXPRs.
5848 (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT
5849 on JBUF_REF (instead of calling `build1' which does not).
5851 * ch-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
5853 * ch-typeck.c (chill_expand_tuple): Deleted.
5854 * ch-parse.y (primval rule): Don't call `chill_expand_tuple';
5855 instead, use initialization machinery for CONSTRUCTORS that
5857 * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
5858 that are created here.
5859 * ch-satisfy (satisfy): Abort in case we would have called
5860 chill_expand_tuple. FIXME: some other code is needed here,
5861 but I don't know what yet.
5863 * ch-parse.y (build_chill_constructor): New function to
5864 propagate TREE_CONSTANT bits to CONSTRUCTORS.
5865 (untyped_expr rule): Use it.
5866 (primval rule): Use it.
5868 * ch-decl.c (do_decl): Call `finish_init'.
5869 * ch-convert.c (convert): If we spontaneously create a CONSTRUCTOR in
5870 this function, make sure the initialization machinery is set up.
5872 * ch-convert.c (digest_structure_tuple, digest_constructor): Add
5875 Fri Dec 31 11:31:01 1993 Michael Tiemann (tiemann@blues.cygnus.com)
5877 * ch-grant.c (chill_finish_module_code): Mark ADDR_EXPR built by hand
5878 as being TREE_CONSTANT. Otherwise it gets bounded by the initializer
5881 * ch-decl.c (do_decl): Change in CONSTRUCTOR handling due to...
5882 * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
5883 rewritten to work with GCC's initialization code. The basic change
5884 was to keep the initializers in sync with the initialization
5885 machinery that `process_init_element' imposes. Both of these
5886 functions now return `void'.
5887 * ch-convert.c (convert): Changed calls to `digest_...' functions.
5889 FIXME: the code handling UNION_TYPE (and variant records) has not
5892 Fri Dec 31 15:32:56 1993 Bill Cox (bill@rtl.cygnus.com)
5894 * ch-lex.l (convert_number): Output the converted number if
5896 * ch-parse.y (signaldef): Set ignore_exprs correctly for a
5899 Fri Dec 31 13:17:48 1993 Bill Cox (bill@cygnus.com)
5901 * ch-parse.y: Cleanup handling of RETURN actions, to distinguish
5902 a RETURN without a value (which cannot have an exception
5903 handler) from a RETURN with a value (which can). Eliminate
5904 some shift/reduce and reduce/reduce conflicts.
5906 Thu Dec 30 17:42:32 1993 Michael Tiemann (tiemann@blues.cygnus.com)
5908 * ch-inout.c (build_chill_writetext): Deal with 2 cases where
5909 types returned from `type_for_size' are not expected. FIXME.
5910 * ch-decl.c (init_decl_processing): Mark `char_type_node' unsigned.
5911 This is required when range checking is enabled.
5913 Thu Dec 30 14:28:25 1993 Bill Cox (bill@rtl.cygnus.com)
5915 DELAY CASE works now.
5916 * ch-decl.c (init_decl_processing): Move rest of tasking-related

5918 * ch-parse.y (delaycaseaction): Pervasive additions/corrections.
5919 (optsetprio): New non-terminal.
5920 * ch-tasking.c (get_task_name): Delete, obsolete.

5927 correct its functioning.
5928 (build_delay_case_end): Correct the code.
5929 (tasking_init): Lots of tasking-related code moved here from
5930 init_decl_processing.
5931 * ch-tree.h: Update, add prototypes.
5933 Wed Dec 29 10:13:10 1993 Bill Cox (bill@rtl.cygnus.com)
5935 * ch-expr.c (build_chill_indirect_ref): Revert change which
5936 failed full regression testing.
5937 * ch-lex.l (name_type_signal): Add debug output.
5938 * ch-parse.y (structured_variable): Add a debug variable.
5940 Wed Dec 29 02:05:51 1993 Bill Cox (bill@rtl.cygnus.com)
5942 * ch-decl.c (get_next_decl): Revert change which failed full
5945 Tue Dec 28 18:20:14 1993 Bill Cox (bill@rtl.cygnus.com)
5947 DELAY actions work now.
5948 * ch-decl.c: Correct spelling in comments.
5949 (get_next_decl): NULL out the decl's TREE_CHAIN before returning
5950 it, to prevent accidental access to the remembered_decls.

5952 * ch-expr.c (build_chill_indirect_ref): Prevent a syntax error from
5953 becoming a seg fault.
5954 * ch-grant.c: Correct a comment.
5955 * ch-loop.c: Delete/correct comments.
5956 * ch-parse.y (delaycaseaction): Add push/poplevel calls. Turn 'sorry'
5957 into rough draft of actual code.
5958 (delayaction): Don't make a new scope here, use get_unique_identifier
5960 (locdec): process event decls here, too.
5961 (mode): Add code to forbid READonly EVENT and BUFFER decls. Delete
5962 code which required EVENTs and BUFFERs to be declared at global scope.
5963 (simple_name_string): Add an EVENTNAME.
5964 * ch-satisfy.c (safe_satisfy_decl): Prevent a syntax error from
5965 becoming a seg fault.
5966 * ch-tasking.c (tasking_setup): Add the event queue's max. length
5967 as the 'entry_point' parameter in the list.
5968 (build_receive_case_start, build_receive_case_label): Defer
5969 calling runtime routine until we know whether we have a signal
5970 or a buffer to wait for.

5973 process_event_decls): Added functions.
5974 * ch-typeck.c (chill_similar): Allow all integers of differing
5975 precisions to be similar.

5979 * gcc.c (CHILL SPECS): Delete references to -M -MM -MD -MMD
5980 options. Delete C-specific defines. Disable piping from
5981 pre-processor to cc1chill (even if -pipe is specified), since cc1chill
5982 rewinds its input for its second pass. Piping still works
5983 from cc1chill to as.
5985 Thu Dec 23 12:31:55 1993 Bill Cox (bill@rtl.cygnus.com)
5987 * ch-tasking.c (decl_tasking_code_variable): Assure that the
5988 tasking_code variable is allocated on the permanent obstack.
5989 (tasking_setup): Lots of changes - handle EVENT/BUFFER max.
5990 queue length (passed as the entry_point parameter).
5991 Other changes to variable names to increase 'self-documentation'
5992 the only kind GNU CHILL will get, for a while..
5994 Wed Dec 22 10:46:31 1993 Bill Cox (bill@rtl.cygnus.com)
5996 * ch-decl.c (do_seize): Delete - it's unused. Fix comments.
5997 * ch-loop.c (build_chill_iterator): Convert BY expression
5998 so loop involving a SET works. Additional errors generated
5999 for numbered SET expression as start or end expression.
6000 * ch-tree.h: Prototypes for future DELAY functions.
6001 * ch-typeck.c: Standard indentation.
6003 Tue Dec 21 15:30:57 1993 Per Bothner (bothner@kalessin.cygnus.com)

6020 * ch-tree.h (CH_EQUIVALENT): Re-defined to use chill_equivalent.
6022 * dbxout.c (dbxout_type): Output the type attribute "@S;" to
6023 distinguish a string from a char array, and to distinguish a
6024 bitstring from regulat (power)set. (Needed for Chill.)
6025 * dbxout.c (dbxout_type): Only check for baseclasses in
6026 type.binfo is a vector. (It is used in Chill for tagged unions.)
6028 Fri Dec 17 09:56:07 1993 Bill Cox (bill@rtl.cygnus.com)
6030 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,

6043 the expressions in a STEP loop.
6044 * ch-tasking.c (rc_state): Add fields to flag SIGNAL and BUFFER
6045 names in receivecasealternative. Generate error messages
6046 if they're mixed in the same receive case.
6047 (process_buffer_decl): Renamed from build_buffer_decl.
6048 * ch-tree.h: Fix prototypes.
6049 * ch-typeck.c (smash_dummy_type): Handle all four kinds of LANG_TYPE

6061 (begin_chill_loop): Build loop-bypass expression in the
6062 type of the start expression, not in the unsigned type.
6064 Tue Dec 14 15:41:32 1993 Per Bothner (bothner@kalessin.cygnus.com)
6066 * ch-decl.c (push_scope_decls): Re-arrange so that normal
6067 (non-seize) declarations are proclaim_decl'd *before* we
6068 handle the ALIAS_DECLs for seizes. The advantage is
6069 that we can now test for (an approximation) to the
6070 'seizeable' concept, thus avoiding duplicate definitions
6071 when a module has both GRANTs and SEIZE ALL.
6073 * ch-expr.c (build_chill_arrow_expr): No longer re-write
6074 addr-of-conversion to pointer-conversion-of-addr.
6075 * ch-expr.c (build_chill_addr_expr): Re-write to just use

6082 * ch-tree.h (chill_root_resulting_mode): Fix typo (missing '_').
6084 * ch-expr.c (finish_chill_binary_op): Use CH_ROOT_RESULTING_MODE
6085 macro (which works on expressions), rather than CH_RESULTING_MODE
6086 (which works on modes, and isn't quite correct).
6087 * ch-tree.h (CH_IS_BOUND_REFERENCE_MODE): New macro.
6088 * ch-typeck.c (chill_read_compatible, chill_compatible):
6089 Use the new macro, which handles NEWMODEs of PTR correctly.

6091 dynamic-length array (and string) types (e.g. slices).
6092 * ch-typeck.c (chill_root_mode): If the mode has a Novelty,
6093 just return it as is. (This is still not 100% correct for
6094 NEWMODE of RANGEs, but is close enough.)
6096 Mon Dec 13 16:27:06 1993 Bill Cox (bill@rtl.cygnus.com)
6098 * ch-parse.y (locdec): Avoid passing IDENTIFIER_NODEs to

6101 of bufdecl closer to its use.

6118 * ch-decl.c (print_lang_identifier): Delete code
6119 to print buffer size - it's no longer kept here.
6120 * ch-parse.y (expand_send_buffer): Renamed from
6122 (locdec): Enable building of a buffer decl.
6123 (optresultspec, optresultattr): Add optional
6124 result attributes such as LOC. Semantics
6126 * ch-tasking.c (expand_send_buffer): Renamed.
6127 * ch-tree.h (build_send_buffer): Renamed.

6142 rather than save_expr.
6143 * ch-typeck.c (build_chill_slice): Don't emit warning

6145 * ch-typeck.c (chill_root_resulting_mode): Handle
6146 correctly the case that one operand is DERIVED and one is VALUE.

6178 Wed Dec 8 09:11:46 1993 Bill Cox (bill@rtl.cygnus.com)
6180 * ch-decl.c (pop_module): Only warn about duplicate grant
6181 statements if they inhabit different files, by examining
6182 inode numbers. Only report compatibility problems in pass 1.

6188 * ch-decl.c (start_chill_function): Handle attributes in pass 1,
6189 rather than in pass 2. (It seems to make more sense that way.)
6190 * ch-parse.y (procedureattr): Build attribute list if pass != 2.
6192 * ch-parse.y (mode): Don't call build_readonly_type in pass 2.
6194 Mon Dec 6 14:35:31 1993 Per Bothner (bothner@kalessin.cygnus.com)

6207 mode compatibility checking for SYN declarations.
6209 * ch-typeck.c (chill_similar): Be more general when checking set
6210 modes for similarity - specifically support calling chill_similar
6211 BEFORE the modes have been satisfied (needed by proclaim_decl).
6212 * ch-decl.c (proclaim_decl): Allow duplicate definitions
6213 of set elements of similar set modes.
6215 * ch-parse.y (caseaction): Call language-independent
6216 expand_start_case rather than c_expand_start_case (which
6217 doesn't allow chars or booleans).
6219 Sat Dec 4 22:16:19 1993 Bill Cox (bill@rtl.cygnus.com)

6802 code variables associated with a process or signal.
6803 * ch-tasking.c (build_gen_inst, build_gen_ptype): Use the decl's

6821 * ch-lex.l: Must initialize tasking-related trees to NULL at start
6822 of each pass, or we lose the fact that the user did or did not
6823 specify a value for each of them.
6824 * ch-parse.y (check_end_label, action, exceptlist): Only output
6825 error message in pass 1.
6826 (sendaction): Add comments.

6831 passes, using do_decl so we can pass the pass 2 value of the
6832 process_type or signal_code to it. Only update the process_type

6834 parameter to know whether to include an init expression.

6851 generation for decls to not use DECL_ASSEMBLER_NAME.
6852 * ch-decl.c: Set DECL_ASSEMBLER_NAME to DECL_NAME.
6853 This matches C, and allows dbxout to emit proper user-level names.

6878 not error_mark_node.
6879 * ch-actions.c (chill_expand_assignment): Allow such borderline
6880 constructs as: LHS OR:= [X].

6884 * ch-typeck.c (chill_compatible): Allow expr to have NULL mode
6885 if it's a CASE_EXPR or COND_EXPR (and not just CONSTRUCTOR).

7123 * ch-tree.c (build_string_type, build_bitstring_type),
7124 ch-convert.c (convert): Use it.
7125 * ch-typeck.c (build_chill_slice): Take length rather than upper
7126 bound. This makes it easier to recognize that A(X UP LENGTH)
7127 really has fixed length. Also, if the argument is string,
7128 mark the slice as a string too. Also, handle varying strings.
7130 * ch-typeck.c (conflate_singleton_strings): New global.
7131 * ch-typeck.c (chill_similar): If conflate_singleton_strings is
7132 set (as it currently is), allow CHARS(1)/BOOLS(1) to be similar
7133 to CHAR/BOOL, as required by the 1984 version of Z.200.
7134 * ch-convert.c (convert_to_char): Convert CHARS(1) to CHAR.
7135 * ch-convert.c ( build_array_type_for_scalar): If input is string,
7137 * ch-convert (maybe_turn_scalar_into_arra), ch-tree.h: Removed.
7138 * ch-convert.c (convert): Convert CHAR to CHARS(1).
7140 This fixes 'X // := Y' and is also a general simplification.
7141 * ch-actions.c (chill_expand_assignment): Convert 'LHS OP := RHS'
7142 to 'LHS := LHS OP RHS' (using stabilize_reference on LHS).
7143 Also, call save_expr on RHS if a multiple assignment.
7144 * ch-parse.y (assignaction): Therefore, no longer need to call
7145 stabilize_reference on RHS.
7146 * ch-typeck.c (build_chill_modify_expr), ch-tree.h: Remove
7147 modifycode parameter. Make it the caller's responsibility to
7148 handle <assigning operator>.
7149 * ch-actions.c, ch-decl.c, ch-except.c, ch-expr.c, ch-grant.c,
7150 ch-loop.c: Fix calls to build_chill_modify_expr accordingly.
7152 Wed Sep 29 18:02:55 1993 Per Bothner (bothner@kalessin.cygnus.com)
7154 * ch-lang.c (string_index_type_dummy), ch-tree.h: New variable.
7155 * ch-decl.c (integer_minus_one_node), ch-tree.h: New variable.
7157 * ch-parse.y (arrayindex: modename): Remove useless code.
7158 * ch-satisfy.c (satisfy): Don't gag on string_index_type_dummy,
7159 * ch-tree.c (build_string_type): Pass string_index_type_dummy as
7160 the parent type of the index range.
7161 * ch-typeck.c (layout_chill_range_type): Recognize and handle
7162 string_index_type_dummy - specifically allow an empty range.
7164 Wed Sep 29 13:36:23 1993 1993 Bill Cox (bill@cygnus.com)
7166 * ch-convert.c (convert_to_reference): Check for loc-identity
7167 mismatches correctly (and remove one of those chill_compatible
7169 * ch-decl.c (decl_tasking_code_var): New function, called from
7170 push_extern_process and push_extern_signal.
7171 * ch-parse.y (end_function): Delete parameter. Check current_function_decl
7172 whether it's actually a process, and whether it has parameters.
7173 Make Michael's change simplifying the pass 2 test, preventing a seg
7175 (procedure, process): Change calls to end_function, remove
7176 code saving value from build_process_header. Delete redundant chill_
7177 phrases from some function calls.
7178 * ch-tasking.c: Remove some redundant _chill phrases from function
7180 * ch-tree.h: Remove some redundant _chill phrases from function
7181 names. Add the CH_VARYING_ARRAY_TYPE macro, call it from
7182 all relevant places.
7183 * ch-typeck.c: Use the new macro. Cast TREE_CODEs to chill_tree_code.
7185 Wed Sep 29 13:07:43 1993 Per Bothner (bothner@kalessin.cygnus.com)
7187 * ch-convert.c (convert_to_reference): Remove redundancies.
7188 * ch-convert.c (convert): Handle convert_to_reference
7189 with a recursive convert call.
7190 * ch-decl.c (do_decl): Add missing compatibility-checking
7191 of initializer (don't depend on convert).
7193 Tue Sep 28 00:02:25 1993 Per Bothner (bothner@kalessin.cygnus.com)
7195 * ch-tree.h (CH_LOCATION_P): New macro.
7196 * ch-typeck.c (layout_chill_range_type): Fix call to
7197 type_for_size, when figuring out a defaulted parent type.
7198 * ch-expr.c (build_chill_lower, build_chill_sizeof): Check
7199 for TREE_CODE_CLASS != 't' rather than == 'd'.
7200 * ch-expr.c (build_chill_function_call): Use CH_LOCATION_P
7201 to check for location, rather than TYPE_CODE_CLASS == 'd'.
7203 * ch-tree.c (build_string_type): Make 2-pass safe. Also,
7204 change parameter to be length, not index type.
7205 * ch-parse.y (mode2), ch-expr.c (build_concat_expr), ch-lex.l
7206 (build_chill_string): Modify callers of build_string_type accordingly.
7207 * ch-lex.l (check_newline): Don't look for # directive inside a
7209 * ch-grant.c (grant_array_type): Make more robust for char-
7210 and bit-strings (allow non-constant sizes). Change parameters
7211 and return types. (raw_decode_mode): Use grant_array_type
7212 for bitstrings. (otherwise): Fix grant_array_type callers.
7214 Mon Sep 27 16:57:57 1993 Per Bothner (bothner@kalessin.cygnus.com)
7216 Remove changes of Sep 15.
7217 * ch-tree.h (CH_SINGLETON_DOMAIN): Removed.
7218 * ch-typeck.c (chill_similar): Don't allow a singleton
7219 powerset to be similar to its domain.
7220 * ch-convert.c (convert_to_boolean): Don't convert a singleton
7221 SET_TYPE constructor to a Boolean.
7223 * ch-actions.c (chill_expand_assignment): Handle IN_EXPR on
7224 LHS of assignment, which is what we're current (temporarily?) using.
7226 Mon Sep 27 06:01:57 1993 Bill Cox (bill@rtl.cygnus.com)
7228 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
7229 ch-grant.c, ch-inout.c, ch-parse.y, ch-satisfy.c,
7230 ch-tasking.c, ch-tree.c, ch-tree.h, ch-typeck.c:
7231 -Wall cleanup. Add prototypes where missing.
7232 Delete unused variables. Cast uses of tree_codes
7233 to chill_tree_code, which they are.
7235 Sun Sep 26 13:09:57 1993 Bill Cox (bill@rtl.cygnus.com)
7237 * ch-decl.c (do_decl): Save initializer in pass zero
7239 * ch-lex.l: Fix comments, indentation.
7240 * ch-parse.y: Standardize error messages to use
7241 uppercase for CHILL keywords rather than quoting them.
7242 Suggestion from docs department.
7243 * ch-tasking.c: Pervasive changes to get processes to
7245 * ch-tree.h: Delete prototypes for functions whic
7246 I made static inside ch-tasking.c.
7248 Sun Sep 26 02:40:02 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7250 * ch-lex.l (yywrap): Call `check_newline' in case the file
7251 started with a line directive.
7253 Sat Sep 25 13:54:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
7255 * ch-decl.c: Expand pre-amble comment.
7256 * ch-decl.c (struct scope, push_module): Use new field
7257 tail_chain_module to build child-module list in order.
7258 (Just to make compiler debugging a little less confusing.)
7260 * ch-decl.c (struct scope): New field weak_decls.
7261 * ch-decl.c (find_implied_types): New interface. Now pre-pend
7262 new enum types to a given input list. This makes it easier to
7263 avoid duplicates, which should at least be more efficient.
7264 Also, handle FUNCTION_DECL.
7265 * ch-decl.c (bind_saved_names): Removed. Distribute its
7266 functionality over new functions (push_scope_decls, pop_scope_decls,
7267 build_implied_names, bind_sub_modules). The goal (which seems to
7268 have been more-or-less attained) was to fix weak name handling.
7269 * ch-decl.c (poplevel): Use new function pop_scope_decls.
7271 * ch-tasking.c (build_signal_struct, build_tasking_message_type):
7272 Use build_decl directly, rather than grok_chill_fixedfields
7273 (which depends on ignore_exprs and has more overhead).
7274 * ch-tasking.c (build_signal_struct): Construct the type
7276 * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
7277 than build_array_ref (which does C-specific "optimizations").
7278 (Hence move my_build_array_ref up earlier in the file.)
7280 Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7282 * ch-tasking.c: Declare static variable `void_ftype_void'.
7283 (chill_tasking_init): Initialize `void_ftype_void' here.
7284 (build_tasking_struct): Use, don't declare `void_ftype_void'.
7285 (generate_tasking_code_variable): Call `do_decl', not
7286 `decl_temp1' to declare TASKING_CODE_NAME.
7287 (tasking_setup): Drop into 1-pass mode so that all
7288 tasking-related declarations are installed in the global
7289 scope. Use correct CHILL types for initializers (since
7290 ptr_type_node doesn't have the right meaning for CHILL).
7291 Also, call `do_decl' instead of `decl_temp1' for
7293 (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
7294 `chill_finish_compile' in sync between passes.
7296 * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
7297 declarations on pass zero. Keep obstacks in sync, and always
7298 call `finish_decl' for pass zero declarations.
7299 (push_chill_extern_function): Keep obstacks in sync, and always
7300 call `finish_decl' for pass zero declarations.
7301 (build_enumerator): Ditto.
7302 (grok_chill_variantdefs): Change PASS test to exclude only
7304 (finish_struct): Ditto.
7305 * ch-expr.c (build_chill_component_ref): Ditto.
7306 (build_chill_binary_op): Ditto.
7307 * ch-tree.c (build_powerset_type): Ditto.
7308 (build_bitstring_type): Ditto.
7309 * ch-typeck.c (build_chill_range_type): Ditto.
7310 (build_chill_struct_type): Ditto.
7312 * ch-decl.c (build_chill_exception_decl): Clarify reasons for
7313 extra pushing and popping of obstacks.
7315 * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
7316 on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
7318 * ch-grant.c (chill_finish_compile): Clear out both
7319 MODULE_INIT_LIST and TASKING_LIST if either contains stuff
7322 * ch-parse.y (rccase_label): Add NAME rules so that pass one
7323 works w/o knowing we're parsing a signal. Simplify SIGNALNAME
7324 rules since we only get SIGNALNAME tokens in pass two.
7325 (sendaction): Ditto.
7326 * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
7327 BUFFERNAME on pass two. The grammar now handles this.
7328 * ch-decl.c (lookup_remembered_decl): Deleted.
7330 Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
7332 * ch-decl.c (lookup_remembered_names): Removed. It was being
7333 misused in ch-lex.l.
7334 * ch-lex.l (name_type_signal): Revert last change. Basically,
7335 we cannot use the C typedef/variable name trick in CHILL, due
7336 due to the language's 2-pass nature.
7337 * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
7339 * ch-tree.h (lookup_remembered_name): Comment out the prototype.
7341 Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7343 * ch-decl.c (do_decl, push_chill_extern_function): Change pass
7344 checks so the pass == 0 case is handled for built-in types.
7345 (push_modedef): Add check for error_mark_node.
7346 (lookup_remembered_decl): New function.
7347 (pushlevel, poplevel) Change pass checks.
7348 (pushdecl): Check type as well for NULL.
7349 (build_enumerator): Handle pass == 0 case.
7350 * ch-lex.l: Use lookup_remembered_decl to get lastiddecl
7352 * ch-parse.y: Set pass to zero to indicate initial decl processing.
7353 Replace NAME references with SIGNALNAME references.
7354 (startaction): Only check copy number if not ignoring actions.
7355 Always call build_chill_start_process.
7356 (optstartset): Don't lookup the instance name.
7357 * ch-tasking.c (generate_tasking_code_variable): Replace
7358 do_decl call with decl_temp1 call.
7359 (build_chill_start_action): Check for ignore_actions here.
7360 (build_tasking_message_type): Layout the type.
7361 (rc_state_type): New structure to keep nested receive-case
7363 (build_chill_receive_case_start, build_chill_receive_case_end):
7367 Fri Sep 24 04:19:15 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7369 * ch-tasking.c (build_chill_receive_case_start): `namedecl'
7370 should be a _DECL, not an IDENTIFIER_NODE.
7372 Thu Sep 23 18:18:24 1993 Per Bothner (bothner@kalessin.cygnus.com)
7374 * ch-decl.c (find_implied_types): Handle VAR_DECLs.
7376 * ch-decl.c (print_lang_identifier): Print IDENTIFIER_OUTER_VALUE.
7377 * ch-actions.c (chill_expand_result): Allow value-less RETURN.

7382 * ch-typeck.c (chill_similar): Repeatedly get parent modes
7383 of ranges, not just once.
7384 * ch-typeck.c (chill_root_resulting_mode), ch-tree.h: New function.
7385 * ch-typeck.c (layout_chill_rang_type): Re-do type-checking
7386 to follow Blue Book better (check for Compatibility).
7388 * ch-tree.h (CH_ROOT_RESULTING_MODE): New macro.
7389 * ch-lex.l (use_seizefile_name, current_seizefile_name), ch-tree.h:
7390 New variables. The latter replaces in_seizefile.
7392 Changes to store in the new DECL_SEIZEFILE field each seize
7393 ALIAS_DECL the name in the most recent use_seize_file directive.
7394 (This requires that use_seize_file directives written to the
7395 grant file be written before the SEIZEs that need it.)
7396 Allow clashing declarations granted into the global scope
7397 (produce a warning), but remember the seizefile case from
7398 (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
7399 The a SEIZE will select the granted decl that matches its
7400 DECL_SEIZEFILE (in other words: grants from the most recent
7401 use_seize_file will be preferred).
7402 * ch-tree.h (DECL_SEIZEFILE), ch-tree.def: New macro.
7403 * ch-tree.h (global_value, IDENTIFIER_GLOBAL_VALUE): Renamed
7404 to outer_value, IDENTIFIER_OUTER_VALUE.
7405 Changes to cause the use_seize_file directives to be written
7406 out in order as they're seen in source.
7407 * ch-lex.l (files_to_seize, next_file_to_seize, last_file_to_seize):
7408 Changed to have type TREE_LIST of pointer to IDENTIFIER_NODE.
7409 * ch-lex.l (handle_use_seizefile_directive): Modify appropriately.
7410 Don't call grant_use_seizefile.
7411 * ch-lex.l (mark_use_seizefile_written): New function.
7412 * ch-grant.c (decode_decl): Write out use_seize_file directive,
7413 if needed, before writing a seize declarations.
7414 * ch-decl.c (pop_module): Handle decls granted into the global
7415 module specially, setting IDENTIFIER_OUTER_VALUE.
7416 * ch-decl.c (lookup_name_for_seizing): Check IDENTIFIER_OUTER_VALUE.
7418 Thu Sep 23 19:05:37 1993 Bill Cox (bill@cygnus.com)

7421 declare the process' tasking_code variable as external.
7422 * ch-parse.y (process): Force ignore_exprs to FALSE while parsing
7424 * ch-tasking.c (sigdef): Move resetting of quasi_signal from here
7426 * ch-tree.h: Add prototype.
7427 * expr.c (store_constructor): Emergency first-aid. Rewrite later.

7431 * ch-expr.c (build_chill_function_call): Move possible call to
7432 chill_start_module_code until we know we're not calling a builtin.
7433 * ch-decl.c (save_expr_under_name): Use pushdecllist,
7434 not proclaim_decl (which provide for popping the decl).
7435 * ch-parse.y (optname): Also allow TYPENAME.
7437 Thu Sep 23 09:18:35 1993 Bill Cox (bill@cygnus.com)
7439 * ch-decl.c (print_lang_decl): Make weak name output more standard.
7440 (print_lang_identifier): Make signal-data flag output more standard.

7442 push_chill_extern_function.
7443 (push_syn_decls, fixup_unknown_type, chill_modes_equiv):
7444 Standardize function header layouts (Makes the tcov script

7465 * ch-grant.c (print_struct): Add missing loop for tag_list.
7466 (print_struct): Look for variant fields by checking for a
7467 UNION_TYPE, not a NULL name, since we must use a dummy name.
7468 * ch-parse.y (structured_variable): Various fixing.
7469 * ch-decl.c (shadow_record_fields): Rename arg decl -> struct_val.
7471 * ch-satisfy.c (safe_satisfy_decl): Disable copying of modes
7472 for NEWMODE (and hence novelty checking), until we figure out
7475 * ch-except.c (finish_handler_array): Use null_pointer_node,
7476 not integer_zero_node (which fails to type-check).

7487 New functions. Handle 2-pass and variant records.
7488 * ch-parse.y (primval DOT name): Use instead of build_component_ref.

7493 arg list before calling build_chill_cast.
7495 * ch-parse.y (defining_occurrence_list): New non-terminal.
7496 Use it to replace locnamelist, synnames, and modenames.
7497 * ch-parse.y: Re-write parsing of variant records.
7499 * ch-decl.c (grok_chill_variantdefs): Now return a FIELD_DECL
7500 rather than just its type.

7502 Change callers appropriately.
7504 * ch-tree.h (TYPE_TAG_VALUES): Add an extra level of TREE_LIST,
7505 to support multiple tag fields.

7528 (handle_one_level): Error, not warning if tree not recognized.
7529 (shadow_record_fields): Rename formal param for readability.
7530 * ch-grant.c (decode_decl): Write proper header for a process.
7531 * ch-parse.y (quasi_pdef): process now uses processparlist,
7532 which doesn't change with the passes.
7533 (quasi_locdec): Call build_chill_reference_type to defer
7534 doing the type's layout.
7535 (processpar): Use paramnamelist, but reformat it into a
7536 list of identifiers in pass 2, so a processpar is the same
7537 structure in both passes.
7538 (locdec): Call build_chill_reference_type to defer doing the
7540 * ch-tasking.c (generate_tasking_code_variable): Call do_decl to

7543 doing the type's layout.
7544 (build_process_header): New code to call make_process_struct.
7545 New pass-2 code to make a PARM_DECL for start_chill_function.
7546 Pass a void_type_node, not a NULL_TREE for an empty list.
7547 Get input for shadow_record_fields from current_function_decl.
7548 (build_buffer_decl): Call do_decl not decl_temp1.
7549 * ch-typeck.c: Reindent to standards.

8785 labels aren't lowercased before their time. Add BEGIN

10238 Major re-write of New module/seize/grant stuff.
10239 Now, a grantfile is a spec module and contains all the
10240 top-level declarations of the granting module, not just
10241 those that are granted. It also contains explicit grant
10242 statments naming those declared names that are granted.
10243 It also has seize statements and use_seize_file directives
10244 to correctly handle transitive dependencies.
10246 * ch-parse.y: Change to allow multiple modules per source file.
10247 Allow spec modules (including quasi definitions) as well as
10249 Allow spec modules inside normal modules; these behave as if
10250 they were outermost. This violates the Blue Book, but is
10251 needed by the new grantfile mechanism. (A grant file is a
10252 spec module that gets included by the use_seize_file directive.)
10253 * ch-parse.y (struct module *current_module, push_module,
10254 pop_module): Support module nesting (for spec modules only).
10256 * ch-tree.h (struct module): New.
10257 * ch-grant.c (granted_decls): New list of declarations
10258 that have been granted into the outermode pseudo-module.
10259 * ch-grant.c (decode_mode): If the decl has a name,
10260 always write the name, not just if the decl has already
10261 been written. Since we write out all decls, we can assume
10262 it will be written later, and depend on the forward
10263 declaration kludges to catch it.
10264 * ch-grant.c (decode_decl): Don't write out _EXTERN.
10265 Instead write out standard (Blue Book) quasi-definitions.
10266 * ch-grant.c (push_granted): New function.
10267 * ch-grant.c (seize_implied_names): New function. Re-write
10268 how set element names are seized when a set type is seized.
10269 * ch-grant.c (chill_seize): Work by seraching the
10270 granted_decls list and copying the declaration.
10271 * ch-grant.c (chill_grant): Write all declarations
10272 declared in this module. Write GRANT statements for
10273 those granted. seize statements for decls seized from
10274 other modules. Write extra syntax to make a complete
10276 * ch-grant.c (grant_use_seizefile): Copy use_seize_file
10277 directives into grant file.
10278 * ch-lex.l (setup_seizefile_read): Call grant_use_seizefile.
10280 * ch-lex.l (struct input_state, current_input_state,
10281 push_input_file, pop_input_file): New (type, variable,
10282 function*2). Used to save and restore state on an input file.
10283 * ch-lex.l: Clean up to handle nested input seizefiles
10284 (needed by new grant/seize mechanism.
10285 * ch-lex.l (skip_to_end_of_directive): New function.
10286 * ch-lex.l (compiler_directive: USE_SEIZE_FILE): Make sure
10287 we skip to the end of the directive *before* we switch
10289 * ch-lex.l (setup_seizefile_read): Prevent reading the
10290 same seizefile twice (otherwise likely with new grant/seize).
10291 * ch-lex.l: Recognize SPEC. Misc cleanups.
10293 * ch-parse.y: Fixed foreward references of types.
10294 Removed the unknown_type_node crock.
10295 * ch-decl.c: Remove all uses of unknown_type_node.
10296 Check for TYPE_SIZE zero instead.
10297 * ch-decl.c (fixup_unknown_type): Make sure new mode
10298 gets copied into old mode. Merge their variant chains.
10299 * c-decl.c (lookup_name_current_level): Make non-static.
10300 * ch-decl.c (lookup_name_current_level): No longer needed.
10302 * ch-parse.y (call): Allow an implicitly defined function
10303 name following the CALL keyword.
10304 * ch-tree.h (struct lang_identifier): Add implicit_decl,
10305 and make sure order of fields matches c-tree.h.
10307 * ch-actions.c (lang_init, build_allocate_memory_call,
10308 build_allocate_globals_memory_call): Fix names (add initial '_')
10309 and prototypes of _allocate_[global_]memory (2nd param is ref).
10310 Use build_chill_function_call, not build_function_call,
10311 so the reference parameter gets handled.
10312 * ch-actions.c. (lang_init): Make sure boolean_{true,false}_node
10313 have boolean_type_node as their types.
10314 * ch-actions.c (build_chill_lower, build_chill_upper): Fix to
10315 work for arrays with BOOLEAN_TYPE ranges (and simplify some).
10317 * ch-except.c: Make sure an end_label is generated,
10318 and jump to it if there is no exception.
10320 * ch-convert.c (convert_to_reference): Strip off NOP_EXPR casts.
10321 * expr.c (expand_expr): Handle NOP_EXPR as Chill-style casts.
10322 (Need cleaning up and FSF installation!)
10323 * ch-parse.y: If taking the address of a cast, move the
10324 ADDR_EXPR inside the NOP_EXPR.
10326 * ch-typeck.c (my_build_array_ref): Simplified, more suitable
10327 versions of build_array_ref from c-decl.c. (E.g. don't barf
10328 if index type is char or bool.)
10329 * ch-typeck.c (build_chill_array_ref): Use my_build_array-ref.
10331 * ch-typech.c (build_chill_bin_type): New function.
10332 Support BIN(N) range type specification.
10333 * ch-parse.y (mode2), ch-lex.l: Recognize BIN(N).
10335 * ch-tree.h (CH_SIMILAR): Redefine in terms of chill_similar.
10336 * ch-typeck.c (chill_similar): New function. Recognize that
10337 that range types are similar to their parent types.
10339 * ch-tree.h: Declare flag_local_loop_counter.
10340 * ch-loop.c: Whether the loop variable is local to the loop
10341 in now controlled by flag_local_loop_counter, instead of
10342 #ifdef'd on CREATE_SCOPE.
10343 * ch-actions.c (lang_decode_option): Recognize flags
10344 "-f[no-]local-loop-counter".
10345 * toplev.c (lang_options): Add Chill flags -f[no-]local-loop-counter.
10347 * varasm.c (make_function_rtl): Due to problems with forward
10348 references, don't rename nested functions in Chill. (Kudge!)
10350 Sun Mar 28 10:12:45 1993 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10352 * ch-lex.l (push_back, readstring): Fix prototypes.
10354 Fri Mar 26 18:32:15 1993 Bill Cox (bill@rtl.cygnus.com)
10356 * ch-parse.y: Put %type directives back into alpha order.

10363 * ch-parse.y (get_type_of): Add function to deal with possible fwd
10364 declared type name. Call it from lotsa places. Add lotsa checks
10365 for error_mark_node. Standardize indentations.

10371 * ch-parse.y (action): Add recognition for allocate_memory and
10372 allocate_global_memory system calls.
10373 (mode2): Remove ill-conceived error check that broke REFs to
10374 as-yet-undeclared types. Check for IDENTIFIER_NODE, lookup its
10375 DECL if there, pass TREE_TYPE of decl to build_pointer_type.
10376 (variantfields, varianthack): Clean up.
10377 (variantfield): Check for IDENTIFIER_NODE, lookup its DECL if
10378 there, pass TREE_TYPE of decl to grok_fixedfields.
10379 (labellist): Explicitly assign error_mark_node to signal error.
10380 * ch-typeck.c (chill_compatible): Report FALSE for bad parameters,
10381 rather than seg faulting.
10383 Thu Mar 25 10:35:58 1993 Bill Cox (bill@rtl.cygnus.com)
10385 * ch-actions.c (lang_init): build_function_type for allocate_memory
10386 and allocate_global_memory runtime routines. Move discrete_type_p
10388 * ch-typeck.c (discrete_type_p): Move here, where it belongs, call it

10398 * dwarfout.c (fundamental_type_code): Add handling of BOOLEAN_TYPEs,
10401 Tue Mar 23 09:03:35 1993 Bill Cox (bill@rtl.cygnus.com)
10403 * ch-actions.c (build_char_array_expr): Just build a type for the

10413 array and its type get on the permanent obstack.
10414 * ch-grant.c (write_grant_file): Don't write the _INIT=name
10415 specifier: It isn't needed, and loses (because of funny
10416 characters in the chill_initializer_name).
10417 * ch-decl.c (push_synmode): Set TYPE_NAME(mode) = syndecl.
10418 * ch-lang.c (finish_chill_enum): Don't allocate a dummy
10419 TYPE_DECL for the enum. I don't think it is needed (?),
10420 and removing it is needed for the change above.
10422 * ch-grant.c (grant_array_type, decode_mode): Remove unused
10424 * ch-grant.ch (raw_decode_mode): New function, based on old
10426 * ch-grant.c (decode_mode); This is now just a wrapper around
10427 raw-decode_mode - but does not call raw_decode_mode if the
10428 type is named and has already been emitted.
10430 Fri Mar 19 11:55:35 1993 Bill Cox (bill@rtl.cygnus.com)
10432 * ch-actions.c: Add prototypes, remove unused variables. Attempt to
10433 continue generating grant file in presence of error (Wilfried's
10434 patch to lang_finish).

10436 after each statement. Move convert call into
10437 chill_expand_assignment from ch-parse.y.
10438 * ch-grant.c: Generally re-order, clean up. Include Per's decode_mode
10439 simplification. Include commented-out hack in decode_mode to return
10440 type's name if type SEIZEd or already GRANTed in this file.
10441 * ch-lex.l: Add prototypes.
10442 * ch-parse.y (assignaction): Move convert call into

10454 assignment in conditional.
10455 * ch-loop.c: Add prototypes, remove unused variable.
10456 * ch-parse.y (structured_variable): Return NULL_TREE is invalid WITH
10457 parameter is seen, don't count it in structured_variable_list. Pre-
10458 vents seg fault when only WITH operand is invalid.
10459 * ch-parse.y (label_spec): Correct assignment within IF expression which
10460 was intended to be equality test. Remove unused variables.
10461 * ch-tree.h: Add prototype. Remove unused EXCP_CODE enumeration, and
10462 prototyping editorial comments.
10463 * ch-typeck.c: Disable generation of code to validate array index for
10464 now. Should be done as a call-back from more generic array_ref code.
10465 Clean up parameter checking. Remove unused variables.
10467 Fri Mar 12 11:57:32 1993 Bill Cox (bill@rtl.cygnus.com)

10502 * varasm.c (output_constant): Prevent seg fault - terminate case
10503 alternative with a 'break'.
10505 Mon Mar 8 17:13:00 1993 Bill Cox (bill@rtl.cygnus.com)
10507 * ch-expr.c (): Move SET_TYPE constructor to expr.c.

10565 * c-decl.c (init_decl_processing): Disable creation of C-specific
10566 builtin functions. They pollute the CHILL name space.

10582 Thu Feb 25 12:09:01 1993 Bill Cox (bill@rtl.cygnus.com)
10584 * c-decl.c (init_decl_processing): Disable initial creation of C-specific
10585 builtins - they pollute the CHILL name space.
10586 * ch-typeck.c (valid_array_index): Correct upper-bound check.
10587 * expr.c (expand_expr): Use actual library name for __inpowerset
10589 * stor-layout.c (variable_size): Disable complaint about variable-
10590 size type or decl at file scope. Perhaps later this s.b. a warning.

10597 * ch-actions.c: Change all builtin functions names to their
10598 actual library names. Change references to boolean_type_node
10599 to references to the TREE_CODE == BOOLEAN_TYPE, to follow the
10601 build_set_expr: Remove length parameter, call powersetlen() instead.
10602 remove handling of CHAR arrays - they're handled in build_char_array_expr.
10603 Call __eqpowerset to test for equality - we can't use a byte-length -
10604 need bitcount instead.
10605 build_chill_compound_expr, internal_build_compound_expr: Copy from C
10606 version that does stuff we don't want.
10607 build_binary_op: Check for in_size_in_bytes return < 0, indicating

10613 build_chill_length: Move VARYING array handling before regular char
10615 * ch-expr.c chill_expand_expr: Disable concatenate code - we need to
10616 the VARYING status of the target to do this correctly. Use powersetlen
10617 for the powerset operations, not a byte length.
10618 * ch-loop.c: Make CREATE_SCOPE #define to enable creation of a new scope
10619 for each CHILL loop, as Z.200 requires. Add powerset and error flags
10620 to loop structure. Evaluate user's powerset expression into a temp,
10621 scan it destructively with __ffsetclrpowerset or __flsetclrpowerset
10622 for powerset loop. Only do loop-end assignments if NOT a powerset
10623 loop, which has much less overhead now.
10624 * ch-tree.h: Add prototype for powersetlen.
10626 Fri Feb 19 08:40:24 1993 Bill Cox (bill@rtl.cygnus.com)

10637 we are going to return 0.
10639 * ch-convert.c (convert_to_reference): Don't use
10640 TYPE_MAIN_VARIANT, because REFTYPE's type may be a newmode
10641 (which must match the type of the expr).
10643 * ch-grant.c (chill_seize): Don't let a type be copied just
10644 because we are seizing it.
10646 * ch-lang.c (finish_chill_enum): Convert TYPE_MIN_VALUE and
10647 TYPE_MAX_VALUE to integer type.
10649 * ch-loop.c (begin_for_range): Set lp->iter_type based on the
10650 tree type of the bounds.
10651 (build_loop_top): type of GE_EXPR and LE_EXPR is
10652 boolean_type_node, not lp->iter_type.
10653 (for_location): Ditto.
10655 * ch-action.c (build_chill_lower,build_chill_upper): Handle
10656 ENUMERAL_TYPE. Also, handle different kinds of arguments more
10659 * ch-parse.y (iteration): Convert start_exp and end_exp to
10660 match the type of modename.
10662 * ch-grant.c (chill_seize_aggr): Search also through anonymous
10665 * ch-grant.c (chill_seize): Check to see if SEIZEITEM has
10666 already been seized, and if so, do nothing.
10668 * c-typeck.c (process_init_constructor): If DEFAULT_VALUE
10669 comes out error_mark_node, set ERRONEOUS.
10671 * ch-actions.c (build_chill_binary_op_1): If EXP is NULL_TREE,
10674 * ch-action.c (chill_comptypes): Test for structural
10675 equivalence of enums.

10891 types such as bitsets.
10892 * ch-tree.c (build_bitstring_type): Set TYPE_MIN_VALUE

10900 that correspond to the Chill source types INT and UINT.

10902 become a configuration option later,

10906 * ch-actions.c (build_chill_unary_op): allow NOT of a set.

10924 * ch-tree.def: add a new tree type - just for varying array

11335 * ch-grant.c, ch-parse.y: Remove all code for explicitly
11336 calling initializer functions. This is not needed, since we
11337 use the same mechanism used for C++ static constructors.
11338 * ch-grant.c (chill_start_module_code): Make sure the
11339 init_name starts with the magic string also used for C++
11340 initializers. Also, don't embed the file name in the name,
11341 just use the module name.
11342 * ch-grant.c (chill_finish_module_code): Now that the
11343 initializer name follows the standard 'collect' convention,
11344 don't need to call assembler_constructor_alias, but can
11345 use the standard assemble_constructor instead.
11346 * varasm.c (assemble_constructor_alias): Remove no-longer-
11348 * ch-parse.y: Move code that is common to the beginning of
11349 all functions to a new macro INIT_ACTION.

11395 * ch-lex.l (check_newline): Use the orginal versions (derived
11396 from the C code, not the simplified, special-case version).
11397 Also, fix that version of check_newline to not call yylex()
11399 * ch-lex.l (yy_input): Call check_newline to handle
11400 newlines and check for # directives.
11401 * ch-lex.l (syntax): Don't recognize #-directives; these
11402 are now handled by check_newline.
11403 * ch-actions.c (lang_init): Call the modified version of
11404 check_newline(). Do this at the *after* we've initialized
11405 standard types, so this can be done while lineno is still 0.

11445 ch-convert.c, where they would seem to belong.
11446 * ch-convert.c (convert): New function, since we no longer
11447 link in c-convert.c.
11448 * ch-expr.c (chill_expand_assignment): Handle by calling
11449 convert() instead of chill_comptypes().
11450 Also handle the LHS being a reference.
11451 * ch-parse.y: Add a procedure call as an action.
11452 * ch-parse.y (locdec, optlocinit): Move handling of
11453 loc-identity declarations from optlocinit to locdec

11481 than a random value.
11482 * ch-lex.l (check_newline): Add a version for chill that
11483 just snarfs the right value for main_input_filename out of
11484 the first line of the input file, without disturbing the
11485 lexer state or requiring it's assistance.
11486 * ch-actions.c (lang_init): Call check_newline, like the
11487 other language frontends, to get main_input_filename set
11488 from first line of input file.

11513 assemble_constructor_alias rather than assemble_constructor.
11514 * varasm.c (assemble_constructor_alias): New function,
11515 like assemble_constructor, but also handles the case where
11516 ASM_OUTPUT_CONSTRUCTOR is not defined and GNU ld is not
11517 being used. Emits a symbol table alias name with the correct
11518 prefix for collect to find and add to the __CTOR_LIST__.
11519 * chillrt/chillrt0.c: Build on previous hack that gets
11520 _build_exceptions into the __CTOR_LIST__, to make it work

11565 chill_expand_result), ch-parse.y <assignaction>:
11566 Use chill_give_type_to_expr().
11567 * ch-typeck.c (chill_handle_case_label): New parameter list,
11568 to handle the (new) conventions for <case_label>, including
11569 default elements and ranges.
11570 * ch-parse.y <expanded_case_label>, ch-typeck.c
11571 (expand_case_expr): Use new version of chill_handle_case_label.
11572 * ch-decl.c (push_syndecls): Change parameters: Instead of
11573 TREE_LIST representing a compete <synonym definition statement>,
11574 just pass the parts of a single <synonym definition> as 3
11575 different parameters. Also, use chill_give_type_to_expr(),
11576 to handle untyped tuples in the RHS.
11577 * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct
11578 a tree - just call push_syndecls() on each <synonum_definition>
11580 * ch-parse.y (exprlist_get_single): Remove; no longer needed.
11581 * ch-parse.y: Handle <tuple> without mode name diferently from
11582 <tuple> with mode name. The latter is a <primval> that can be
11583 in most contexts, but if the <mode name> is missing, the <tuple>
11584 is only allowed in certain contexts. Use the new non-terminal
11585 <untyped_expr> to indicate those contexts where untyped tuples
11586 (and case expressions) are valid because the expression gets a
11587 type from its context (such as the RHS of an assignment).
11588 Use chill_give_type_to_expr in those contexts.
11590 Sat Dec 19 14:01:26 1992 Bill Cox (bill@cygnus.com)
11592 * ch-actions.c, ch-loop.c, Makefile.in: looping stuff.
11594 Sat Dec 19 10:16:20 1992 Bill Cox (bill@cygnus.com)
11596 * ch-parse.y: clean up warning messages from byacc. bison
11597 still complains thrice.

11620 a default initializer element.
11621 * ch-parse.y: Implement default elements for tuples
11622 (as in '(else):' and '(*):' ).
11624 * ch-parse.y: Previous change to dis-ambiguate case-labels
11625 seems to have allowed getting rid of all of the expr_or_list hair.
11626 * ch-decl.c (do_decls): Undo Tiemann's change to "Handle
11627 initialization of multiple variables by a tuple" - the
11630 Wed Dec 16 11:17:53 1992 Bill Cox (bill@cygnus.com)
11632 * ch-parse.y: complete re-write of DO statement handling.
11633 now operational, except WITH is stubbed out. Improved
11634 syntax error message.
11635 * ch-actions.c: DO support: high_domain_value(), low_domain_value ().
11636 * ch-expr.c: fixes to IN_EXPR handling.
11638 Tue Dec 15 17:15:13 1992 Jim Wilson (wilson@sphagnum.cygnus.com)

11649 variables by a tuple.
11651 * ch-decl.c (do_decls,start_chill_function): Make DECL public
11652 if we're doing a GRANT ALL at top level.
11654 * ch-lang.c (build_range_type): Deal with typecast to CHAR in

11660 Mon Dec 14 14:58:32 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11662 * ch-lex.l (get_chill_{linenumber,filename}): New functions.
11663 (convert_number): Use LONG_TYPE_NODE instead of INTEGER_TYPE_NODE.
11665 Mon Dec 14 13:36:44 1992 Bill Cox (bill@cygnus.com)
11667 * expr.c: install and test newer Pascal IN_EXPR code,
11668 but don't activate it - it's very verbose.
11670 Mon Dec 14 00:22:49 1992 Fred Fish (fnf@cygnus.com)
11672 * Makefile.in (LANGUAGES): Add chill.

11702 have been implemented but not (yet) declared.
11704 Sat Dec 12 00:17:23 1992 Per Bothner (bothner@cygnus.com)
11706 * c-typeck.c (process_init_constructor): Warn about duplicate
11707 labels for labelled initializer elements.
11708 * ch-lex.l (various operator tokens, such as "+"): Don't
11709 set yylval.code to a TREE_CODE; this is better done in parser.
11710 * ch-parse.y: Some work with case labels and tuples.
11711 Get literal range as tuple (and case) labels working.
11712 Fix some problems introduced by recent grammar overhaul.

11716 * ch-actions.c, ch-parse.y ch-tree.h ch-expr.c, ch-typeck.c:
11717 got long, real expressions working. We can also call a func-
11718 tion and use its return value.
11720 Thu Dec 10 14:45:17 1992 Per Bothner (bothner@cygnus.com)
11722 * ch-parse.y: Major change to remove or at least identify
11723 parser ambiguities. One result: We now allow actions that
11724 start with '(', as required by teh Blue Book. This does break
11725 some things; look for FIXME for things that need work.
11726 * ch-typeck.c (chill_expand_case_expr): We need an extra
11727 level of looping to (in the future) support <case label
11728 specification>s with more than one <case label list>.

11757 indicate we are done with initialization.
11759 * ch-decl.c (do_decls): Set TREE_PUBLIC if we are doing a
11761 (start_chill_function): Ditto.
11763 * ch-lex.c (convert_bitstring): Set TREE_CONSTANT.
11764 (compiler_directive): Don't confuse compiler directives with
11765 equality comparison operators.
11767 * ch-parse.y: Clear CURRENT_LOCNAMELIST after calling do_decls.

11780 * tree.def: Move CARD_EXPR and SET_LE_EXPR back down with the other
11781 Pascal-required ones, since C++ no longer needs them. When
11782 Chill's public, a comment can be added to the effect that
11783 SET_LE_EXPR is also used by Chill.
11785 Fri Dec 4 12:05:01 1992 Bill Cox (bill@cygnus.com)
11787 * Restore CARD_EXPR and SET_LE_EXPR to tree.def.

11826 (push_newmode,push_synmode): Call `fixup_unknown_type' when we
11827 see a declaration that uses `unknown_type_node'. FIXME.
11829 * ch-grant.c (decode_constant): New function.
11830 (decode_decl): Call `decode_constant' for CONST_DECLs.
11832 * ch-lex.l (char action): Use ridpointers instead of
11833 lookup_name to get "char"'s declaration.
11835 * ch-parse.y: Call `build_lang_decl' instead of `build_decl'
11836 when we need to build a TYPE_DECL.
11838 Tue Dec 2 09:44:05 1992 Bill Cox (bill@cygnus.com)
11840 * ch-typeck.c: clean up a gcc warning with a forward
11841 declaration of build_string_type.
11843 Tue Dec 1 16:51:05 1992 Bill Cox (bill@cygnus.com)
11845 * ch-actions.c: completely remove those builtin calls
11846 that are duplicated in c-decl.c
11848 Tue Dec 1 16:38:51 1992 Fred Fish (fnf@cygnus.com)
11850 * ch-actions.c (lang_init): Ifdef out initializations for
11851 __builtin_abs and __builtin_fabs, since they are duplicates of
11852 initializations in c-decl.c, and trigger spurious warnings.
11854 Tue Dec 1 16:35:18 1992 Bill Cox (bill@cygnus.com)
11856 * ch-parse.y: make size() work with a typename argument.

11883 Mon Nov 30 17:35:33 1992 Fred Fish (fnf@cygnus.com)
11885 * chillsh: New script frontend (ala g++), installed as "chill".
11886 Can't be called "chill.sh" because make tries to cat it into the
11887 "chill" directory. Can't be called just "chill" cause that's
11888 already there as a directory.
11889 * Makefile.in: Add rules to install chillsh as "chill".
11890 * chill/libchill.c: Temporarily ifdef out stuff that wants
11891 to conflict with i486/SVR4 runtime or wants to pull in librmt.a,
11892 which itself causes linkage to fail.
11894 Mon Nov 30 16:28:19 1992 Bill Cox (bill@cygnus.com)
11896 * ch-lex.l: added keywords for TRUNC, ROUND, FLOAT, LFLOAT
11897 conversion routines.
11898 * ch-parse.y: added %tokens for TRUNC, ROUND, FLOAT, LFLOAT.
11899 Added production for SIZE(expr).

11904 * ch-lex.l, ch-parse.y: Translate token PFEIL into English ARROW.
11905 * ch-parse.y (op6): Remove handling of string repetition operator,
11906 until we can figure out a way to parse it correctly.

11908 * ch-parse.y (tuple): Merge the two variants using optmodename.
11909 * ch-parse.y (location): Add semantic actions for
11910 dereferencing operator ->.

11920 pred, succ, etc. Put flex -a option into Makefile.in, so we can
11921 clean up the lexer soon.

11940 Handle mode-unspecified tuples and case expressions in
11941 the context of RETURN and RESULT actions.
11942 * chill.y (assignaction): Handle case expressions in the
11943 context of the RHS of an assignment action.
11944 * chill.y (caseaction): Remove spurious duplicate OF in grammar.
11945 * chill.y: Handle labeled structure tuples.
11946 * chill.y: New rules to parse CASE expressions.

11953 tuple (constructor) given an expected (context) type.
11954 * chill.y: Implement 'LHS := TUPLE' using expand_chill_tuple,
11955 using the mode of the LHS and the expected type of the TUPLE.
11956 * chill.y: Implement initialization.
11957 * chill.y: Fix some syntax bugs (forbidlist must be surrounded
11958 by parentheses), and remove or note ambiguities.
11959 * chill.y: Started converting layout style to be like c-parse.in.
11960 * chill.y: Implement IF expressions.
11961 * chill.y: Added syntax rules for tuples. Labelled and unlabelled
11962 array tuples should now work (in some contexts).
11963 * ch-actions.c: Initialize doing_chill_thang to 1.
11964 * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
11965 initializer, to make pushdecl and finish_decl work.
11966 * c-decl.c (convert_for_assignment): If Chill, don't convert
11967 function and arrays into pointers. (Maybe functions should
11968 still be converted?)
11969 * c-typeck.c (grokdeclarator): Allow functions in Chill
11970 to return arrays and functions.
11972 Mon Nov 16 15:40:47 1992 Per Bothner (bothner@rtl.cygnus.com)
