3446 handling as EQ_EXPR, and inverting the result.
3447 * decl.c (init_decl_processing): Don't define unused __eqpowerset.
3449 * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
3450 type boolean_type_node, not void_type_node. (Fixing this
3451 avoids a crash in the back-end.)
3453 * grant.c (decode_constant): In a CALL_EXPR, if the argument
3454 list is not a TREE_LIST (as in string repetiation), don't
3457 Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3459 * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
3460 CONST_DECL is from a SET definition. (This is safer than
3461 checking that the type is ENUMERAL_TYPE, because synonym
3462 definitions may have a NULL TREE_TYPE.)
3463 Also, if we have duplicate enums whose types are identical,
3465 * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
3466 an extra 'quiet' parameter, which is true if we're called from
3467 bind_sub_modules. (In that case an error message about duplicated
3468 decls would be repeated later, so suppress it.)
3470 * parse.c (stmt_count): Removed, not used.
3471 (INIT_ACTION): Call emit_line_note only if !ignoring.
3472 (parse_begin_end_block): Do INIT_ACTION even if ignoring.
3474 Fri Aug 5 12:39:11 1994 Per Bothner (bothner@kalessin.cygnus.com)
3476 * parse.c (parse_untyped_expr): Add missing semi-colon.
3478 Thu Aug 4 17:40:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
3480 * parse.c (parse_untyped_expr): Fix various problem for the
3481 case that we see a '(': Add missing 'case' keyword.
3482 Only recurse if '(' is followed by 'if', 'case' or '[',
3483 and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
3485 * parse.c (parse_send_action): Remove extra nreverse.
3487 Thu Jul 28 04:00:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3489 * expr.c (build_allocate_global_memory_call, build_allocate_memory_call):
3492 Tue Jul 26 22:48:15 1994 Michael Tiemann (tiemann@blues.cygnus.com)
3494 * parse.c (parse_untyped_expr): Added missing "case" before LPRN.
3495 Added a missing call to `require' as well.
3497 Tue Jul 19 10:30:12 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3499 * lex.l (yywrap): Define as yywrap_chill to avoid conflicts with
3500 the extern declaration in the flex skeleton.
3502 Mon Jul 18 23:06:04 1994 Per Bothner (bothner@kalessin.cygnus.com)
3504 * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
3505 Check the type of the instance expr using CH_COMPATIBLE,
3506 and not just == instance_type_node. (This allows
3507 the expression to have mode READ INSTANCE).
3508 * tasking.c (build_instance_type): Give instance_type_node
3509 a non-null novelty (i.e. different from a struct).
3510 * tasking.c (build_receive_case_start, build_delay_case_start):
3511 Check that for a location using CH_LOCATION_P.
3513 Mon Jul 18 13:22:23 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
3515 * expr.c (finish_chill_unary_op): Use TREE_SET_CODE not TREE_CODE
3516 to modify a tree code.
3518 Mon Jul 18 11:24:57 1994 Bill Cox (bill@rtl.cygnus.com)
3520 * convert.c (digest_structure_tuple): Fix thinko in TREE_CODE
3523 Mon Jul 18 05:40:15 1994 Doug Evans (dje@canuck.cygnus.com)
3525 * decl.c (warn_bad_function_cast): Define so cc1chill will link.
3527 Thu Jul 14 18:37:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3529 * parse.c (parse_send_action): Do tree_cons *before* checking
3532 Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3534 * convert.c (digest_structure_tuple): Don't use convert to
3535 coerce initial value, use chill_convert_for_assignment instead.
3536 (Thus we also get range_checking.)
3538 * expr.c (build_chill_card): Use force_addr_of instead of
3539 build_chill_addr_expr.
3541 * loop.c (build_temporary_variable): Stylistic tweak.
3542 * loop.c (maybe_make_for_temp): Initialize temp using
3543 explicitly, not using assignment. Avoids a problem if
3544 the expression is read-only.
3545 * typeck.c (smash_dummy_type): Always used the saved TYPE_NAME
3546 and CH_NOVELTY_FLAG.
3548 Wed Jul 6 20:12:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3550 * expr.c, ch-tree.h (finish_chill_unary_op): New function,
3551 based on code ripped out of build_chill_unary_op.
3552 (build_chill_unary_op): Call finish_chill_unary_op unless pass==1.
3553 * satisfy.c (satisfy): Call finish_chill_unary_op when needed.
3555 Mon Jun 27 11:29:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3557 * tree.c (save_if_needed), ch-tree.h: New function.
3558 * typeck.c (build_chill_slice_with_range,
3559 build_chill_slice_with_length): Call save_if_neeed on array arg.
3560 * expr.c (varying_to_slice): Re-write to use save_if_needed.
3562 * typeck.c (extract_constant_from_buffer): Handle BOOLEAN_TYPE.
3564 Mon Jun 27 01:11:10 1994 Wilfried Moser (moser@rtl.cygnus.com)
3566 * inout.c (build_chill_io_list_type): Change layout of __tmp_WIO_list
3567 that it is always the same, regardless if compiled with -fpack
3570 Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3572 * lex.l (yywrap): Kludge to work around mis-synchronization
3573 between lexer (which read ahead) and parser: Don't emit
3574 (left-over) uze_seizefile directives at the end of file.
3576 * typeck.c (build_chill_array_ref): Allow the derived
3577 array indexing syntax for arrays of bit strings.
3578 Add a comment explaining why.
3580 * typeck.c, ch-tree.h (string_assignment_condition): Change
3581 the interface. Return a boolean expression (which can be
3582 used in a conditional at run-time); never expand anything.
3584 * actions.c (chill_convert_for_assignment): Check
3585 string_assignment_condition here, rather than in callers.
3586 * actions.c (chill_expand_assignment): Don't need to check
3587 string_assignment_condition here.
3588 * expr.c (build_chill_function_call): Likewise.
3589 * satisfy.c (safe_satisfy_decl): Update accordingly.
3590 * decl.c (do_decl): Simplify testing and conversion by
3591 deferring everything to chill_convert_for_assignment.
3593 * parse.c: Combine the two variables 'ignore_exprs' and
3594 'ignore_actions' into one variable called 'ignoring'.
3595 * ch-tree.h: Add 'extern int ignoring'.
3596 * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
3597 Rename ignore_actions and ignore_exprs to ignoring.
3598 Remove unneeded extern declarations.
3599 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3600 build_chill_arrow_expr, build_generalized_call, build_delay_action,
3601 build_buffer_type, build_event_type): I changed my mind. It is
3602 cleaner to check for 'ignoring' in the parser, rather than here.
3603 * parse.c (parse_action, parse_primval, parse_opt_mode):
3604 Therefore we must check for ignoring here.
3605 * parse.c (parse_loc_declaration): Set ignoring in pass 2
3606 when parsing the mode.
3608 * tasking.c (generate_tasking_code_variable): Do arithmetic
3609 on signal_code etc using unsigned rather than signed shorts.
3611 * grant.c (static char* current_grant_modename): Removed.
3612 * grant.c (decode_decl case CONST_DECL): Remove error message.
3614 * Make-lang.in (CHILL_SRCS): Add $(srcdir)/ch/parse.c.
3615 * Makefile.in: Fix dependencies for parse.o.
3616 Remove some duplicate dependencies for $(TREE_H).
3618 Mon Jun 13 14:25:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3620 * typeck.c (build_chill_cast): Allow a value cast between
3621 non-discrete object of the same size, but with a pedwarn.
3622 * typeck.c (bit_string_assignment_condition,
3623 char_string_assignment_condition): Merge near-duplicate functions
3624 and place the code in string_assignment_condition.
3626 * decl.c (parm_flag, declare_parm_level, in_param_level_p):
3628 * decl.c (start_chill_function, finish_chill_function): Make
3629 parameter level have same nesting level as body, as required by Z200.
3630 * decl.c (switch_to_pass_2): Always exit if an error has been found.
3631 * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
3632 generated from GRANT ALL.
3633 * decl.c (lookup_name_for_seizing): Don't seize from
3634 the nesting level of builtins (predefined objects).
3635 * decl.c (lookup_name_for_seizing): Make more robust on error.
3637 * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
3638 be 'RESULT' (or 'result'). This makes it more accessible from gdb.
3639 Also, use do_decl to declare it, so that debugging symbols are
3640 generated. And, re-arrange so that actions that need to
3641 be done both passes (such as push_levels) use the same code.
3643 * parse.c (get_type_of): If ignore_exprs, don't lookup name.
3644 * parse.c (end_function): Fix poplevel params.
3645 * parse.c (expect): Don't read forwards on an error.
3646 * parse.c (parse_field): Don't define two tag_list locals!
3647 * parse.c (parse_pass_1_2): Better error message.
3649 * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
3650 parse_opt_mode, rather than vice versa. If parse_opt_mode
3651 returns NULL_EXPR, then parse_mode gives an error.
3652 Change parse_opt_mode (and any functions it calls) to only
3653 return NULL_TREE if there is no mode (even on ignore_exprs).
3654 (parse_set_mode, parse_structure_mode, parse_procedure_mode):
3655 Never return NULL_EXPR.
3656 * tasking.c (build_buffer_type, build_event_type): Return
3657 void_type_node instead of NULL_EXPR if ignore_exprs is true.
3659 * parse.c (parse_synonym_definition): Call parse_untyped_expr
3660 only if we have a mode.
3661 * parse.c (parse_send_action): Parse list of untyped_expr's,
3662 rather than a list of (typed) expressions.
3663 * parse.c (parse_primval): Emit error if '[' seen without
3664 preceding mode name. (If this is to be allowed, call
3665 parse_untyped_expr instead.)
3667 * parse.c (parse_array_index): Renamed to ...
3668 (parse_index_mode): ... to match Z200 terminology.
3669 Re-write to resolve some of the nastier ambiguities,
3670 and allow things like ' CHAR(10) : CHAR(20) '.
3672 * parse.c (parse_tuple_element): Change interface to return
3673 reversed list, so don't call nreverse.
3674 * parse.c (parse_tuple): No longer nreverse element list here.
3675 * parse.c (parse_opt_element_list): Do nreverse here instead.
3676 * parse.c (parse_case_label_list): Call nreverse at end.
3678 Fri Jun 10 15:36:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
3680 * typeck.c (chill_similar): Remove bogus "else".
3682 Wed Jun 8 00:01:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
3684 * ch-tree.h (TYPE_ARRAY_MAX_SIZE): New macro (and comment)
3685 to make it clearer that we are using TYPE_MAX_VALUE in a special way.
3686 * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
3687 * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
3688 * convert.c (convert): When converting a fixed string/array
3689 to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
3690 of (the type of) the padding.
3691 * convert.c (convert): If the concatenation is non-constant, use
3692 the low-level 'build' to set the type of the result (which is usually
3693 a fixed-size array) rather than depend on build_chill_binary_op
3694 to figure it out (it's unable to simplify the size to a constant).
3696 Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
3698 * lang.c (lang_decode_option): Let -fspecial_UC imply
3699 -fno-ignore-case without requiring it explicitly.
3700 * lang.c (lang_decode_option): Support (experimentally)
3701 the -fpack and -fno-pack flags.
3703 Thu Jun 2 20:49:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3705 * configure: Add support for --program-prefix and --program-suffix.
3707 Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3709 * convert.c (digest_constructor): Check that initial value
3710 is compatible with element mode before calling convert.
3711 * typeck.c (chill_compatible): A string mode is not compatible
3712 with an untyped constructor.
3713 * decl.c (do_decl): Clean up error messages. Use error_with_decl.
3715 * ch-tree.h: Fix inconsistencies: bool_true_node ->
3716 boolean_true_node, and bool_false_node -> boolean_false_node.
3717 * typeck.c (valid_array_index_): Minor simplification.
3719 Tue May 31 04:33:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3721 * inout.c (build_chill_writetext): Add correct processing
3722 of POWERSET RANGE (setmode).
3724 * lex.l (same_file): Add searching for file(s) in
3727 Fri May 27 14:22:42 1994 Per Bothner (bothner@kalessin.cygnus.com)
3729 * Make-lang.c (CHILL.mostlyclean, CHILL.distdir): Don't list
3730 yacc/bison output files, since the grammer is no longer in yacc.
3731 * config-lang.in (diff_excludes): Likewise.
3733 Thu May 26 16:38:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3735 * gperf, hash.h, lex.l, parse.h: Rename PROCESS_TYPE token
3736 (in some files spelled PROCESS_TYPE_ to avoid clashes
3737 with the PROCESS_TYPE tree_code) to PROCESS_TYPE_TOKEN.
3739 Thu May 26 02:18:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3741 * timing.c (build_cycle_start): Change call to __define_timeout.
3742 * decl.c (init_decl_processing): Change definitions of
3743 __define_timeout and __wait_timeout.
3745 Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
3747 Replace yacc-based parser with a recursive-decent parser.
3748 (This may seem backwards, but Chill [like C++] is not a
3749 language that is remotely LALR(1). Using a R-D parser
3750 allows us to use look-ahead and to back-up to resolve the
3751 difficult ambiguities.)
3753 * parse.c, parse.h: New files, containing new r-d parser.
3754 * Makefile.in: Update accordingly.
3755 * actions.c (chill_convert_for_assignment): Don't return
3756 NULL_EXPR if ignore_exprs is true. It simplifies the parser
3757 if we consistently reserve NULL_EXPR for a missing expression.
3758 * expr.c (build_chill_function_call): Likewise.
3760 * lex.l: Tweaks for new parser.
3761 * lex.l (prepare_paren_colon, paren_paren_colon_level,
3762 paren_level): Ugly hack no longer needed.
3764 * expr.c (build_chill_function_call): Cleanup.
3765 Call chill_convert_for_assignment to convert IN/INOUT
3766 paramaters on both input and output. For LOC parameters,
3767 give error if actual is a non-referable location.
3768 * actions.c (convert_for_assignment): Add new parameter (a
3769 "place" string used in error messages).
3770 * actions.c (adjust_parm_or_field): Removed.
3771 * actions.c (chill_expand_assignment): Take just a single LHS,
3772 and move support for multiple assignments to ...
3773 (expand_assignment_action): ... here. Some cleaning up.
3774 * timing.c (build_cycle_start): Adjust accordingly.
3775 * actions.c (expand_assignment_to_varying_array): Likewise.
3776 * tasking.c (many places): Ditto.
3777 * ch-tree.h: Fix declarations appropriately.
3779 * parse.c (parse_defining_occurrence_list): Return a single
3780 IDENTIFIER_NODE (instead of a singleton list) in the common
3781 case. Minor complication to save a minor amount of space.
3782 * decl.c (do_based_decls): Move guts of code into ...
3783 (do_based_decl): ... this new function.
3784 * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
3785 * decl.c (push_syndecl): Replace by ...
3786 (push_syndecl): ... (which only supports a single name).
3787 (push_modedef): Only handle a single name.
3788 * tasking.c (build_process_header, build_signal_struct_type):
3791 * expr.c (build_generalized_call): Handle string repetition.
3792 * expr.c (build_chill_repetition_op): Change interface.
3793 * grant.c (decode_constant): Allow parameter list to be
3794 a non-TREE_LIST. (Used for string repetition.)
3796 Wed May 25 11:28:48 1994 Per Bothner (bothner@kalessin.cygnus.com)
3798 * lex.l (make_identifier): Replaced by ...
3799 (read_identifier, handle_name): ... new functions.
3800 * lex.l: Parse an identifiers using read_identifier using
3801 read_identifier and handle_name, rather than having [f]lex
3802 do it. (One reason is that lex uses a fixed-size buffer.)
3804 * lex.l (read_directive, skip_directive): New functions.
3805 Use them to parse compiler-directives, instead of rather
3806 ugly and useless use of lexer start conditions.
3808 Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3810 * decl.c (unnamed_module_number): Renamed to ...
3811 (module_number): .. and make non-static.
3812 (push_module): Always increment module_number.
3813 * lex.l (yywrap): Print warning if no modules seen.
3815 * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
3816 decl to current_seizefile_name (which is unreliable).
3817 * grant.c (chill_grant): Set it here instead.
3819 * expr.c (fold_set_expr): Use int_size_in_bytes instead of
3820 TYPE_PRECISION (which is not defined for a SET_TYPE).
3822 Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
3824 Cleanup to remove need for variables in common storage.
3825 * decl.c: Remove unused use of current_obstack.
3826 * actions.c (maybe_chill_check_decl): Remove unused function.
3827 * actions.h, lang.c: Remove uses of doing_chill_thang.
3828 * ch-tree.h (void_list_node): Make extern (rather than common).
3829 * decl.c (void_list_node): Add definition.
3831 Thu May 19 06:54:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
3833 * configure (build): Build canon_host and canon_target
3834 to pass it to all subsequently generated Makefiles (needed
3835 for testsuite/execute in case of cross build).
3837 Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
3839 * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
3840 the input type, which loses with the no-longer-new 2-pass
3841 implementation, since the input "type" could be an IDENTIFIER_NODE.
3842 * grant.c (raw_decode_mode): Rename to decode_mode.
3844 Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3846 * typeck.c (chill_location): Neither a STRING_CST nor a
3847 CONSTRUCTOR is a location.
3848 * typeck.c (chill_root_mode): Convert a function to a
3849 pointer-to-function.
3850 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3851 build_chill_arrow_expr): If ignore_exprs, return operand
3852 rather than NULL_EXPR. This makes it easier for the parser to
3853 distinguish missing expressions.
3854 * expr.c (build_max_min): Convert the lower bound of a
3855 set to a long before calling run-time routine.
3856 * expr.c (build_chill_pred_or_succ): Use discrete_type_p
3857 to check the argument type.
3858 * expr.c (build_chill_arrow_expr): If argument is not a location,
3859 do a predwarn if it is a STRING_CST or has function type.
3861 Tue May 17 06:05:13 1994 Wilfried Moser (moser@rtl.cygnus.com)
3863 * configure (build): Remove building of canon_host and canon_target.
3864 It doesn't work in any case.
3866 Mon May 16 02:10:35 1994 Wilfried Moser (moser@rtl.cygnus.com)
3868 * configure (build): Build canon_host and canon_target
3869 to pass it to all subsequently generated Makefiles (needed
3870 for testsuite/execute in case of cross build).
3871 * Make-lang.in (chill-runtime): Change chill to CHILL in the case
3872 statement to build chill-runtime automatically.
3874 Mon May 9 15:30:08 1994 Doug Evans (dje@canuck.cygnus.com)
3876 * Makefile.in (FLAGS_TO_PASS): Define.
3878 (../cc1chill): Depend on $(OBJDEPS) $(C_OBJS).
3879 * Make-lang.in (cc1chill): Delete dependency on $(OBJS) $(BC_OBJS).
3880 (CHILL.mostlyclean): Use `mostlyclean' as recursive target.
3882 Sun May 8 13:05:00 1994 Per Bothner (bothner@cygnus.com)
3884 * Make-lang.in (cc1chill): Should not depend on libgcc.a.
3886 Thu May 5 18:58:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
3888 * decl.c (copy_lang_decl): New (dummy) function.
3890 Mon May 2 14:33:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
3892 * parse.y (sendaction): Fix thinko (in sense of condition).
3893 * tasking.c (build_receive_case_label): Another thinko.
3895 * parse.y (optsigdest): Force ignore_exprs to 0 while parsing
3898 * decl.c (build_chill_function_type): Don't call layout_type
3899 (since that may prevent parameter or result types being
3900 properly satisfied).
3901 * satisfy.c (satisfy): Layout FUNCTION_TYPEs.

3906 * parse.y (optresultspec): Call build_chill_reference_type, rather
3907 than build_reference_type (which incorrectly sets TYPE_SIZE).
3908 * parse.y (range_or_mode): Rename to plain range, since it
3909 no longer matches modename.
3910 * actions.c (chill_handle_case_label_range): New function, with
3911 functionality moved out of chill_handle_case_label.
3912 * actions.c (chill_handle_case_label): Handle here the case that

3926 * lex.h, lex.c: Remove lastiddecl.
3927 * lex.l (name_type_signal): Simplify. We no longer check for

3954 * parse.y (ioindexmode): Removed; use index_mode instead.
3955 * expr.c (build_generalized_call): If args is a RANGE_EXPR,
3956 we have either a slice or a range mode, depending on func.
3957 * parse.y (index_mode): If we got an 'expr', only allow a name,
3959 * parse.y (call): A slice with both end points can be a range
3960 mode, so defer handling to build_generalized_call (or index_mode).
3962 * typeck.c (build_chill_slice_with_length): Fix type-checking.
3963 * typeck.c (chill_novelty): Undo (part of) change of April 28:
3964 The novelty of a range mode is the novlety of the parent.

3966 if argument has non-nil novelty.
3968 * decl.c (global_bindings_p): Return -1 as true, for the sake

3971 Fri Apr 29 13:42:43 1994 Per Bothner (bothner@kalessin.cygnus.com)
3973 * parse.y: Remove TYPENAME and modename. These are now plain
3974 NAMEs. Modify parsing actions appropriately.
3975 * expr.c (build_generalized_call): Handle the case that
3976 TREE_CODE (func) == TYPE_DECL (as in a cast).
3977 * lex.l (name_type_signal): Never return TYPENAME.
3978 * parse.y (get_type_of): If pass 1, just return the argument.
3980 * decl.c (do_decl): If an initializer has the wrong type,
3981 replace it by NULL_TREE, to avoid subsequent errors.

4027 * typeck.c (smash_dummy_type): Handle the special case of a
4028 NEWMODE of a range mode, as required by Z200, by creating a
4029 new parent mode with the new novelty (and casting the min
4030 and max of the range to teh new parent mode).
4031 * typeck.c (chill_novelty, chill_root_mode): Remove special
4032 kludges for of NEWMODE ranges.

4350 at semantic level if not the NAME of a type).
4351 * typeck.c (build_chill_cast): Re-enable some casts.
4352 * satisfy.c (safe_satisfy_decl): Remove redundant CONST check.

4369 string assignment case.
4370 * expr.c (chill_expand_expr): Now that we're using build_chill_function_call,
4371 the actual parameters need to be converted to the unsigned long
4372 type explicitly. Do that.
4373 * satisfy.c (safe_satisfy_decl): Correct range-checking code.
4375 Mon Mar 21 16:25:07 1994 Bill Cox (bill@rtl.cygnus.com)
4377 * Makefile.in: Correct prediction of grammar conflicts.
4378 * actions.c(check_range): Fix reference to NULL_TREE pointer.

4381 * satisfy.c (safe_satisfy_decl): Add range-check for a SYN's value.
4383 Mon Mar 21 13:29:23 1994 Per Bothner (bothner@kalessin.cygnus.com)
4385 * typeck.c (layout_chill_range_type): Instead of tree_int_cst_lt
4386 use compare_int_csts (which is more robust when signedness differs).
4387 Also, convert the bounds *after* doing range checking.
4389 * ch-tree.def (SET_IN_EXPR): New.
4390 * expr.c (chill_expand_expr): Code to expand SET_IN_EXPR,
4391 moved from expand_expr in ../expr.c. Also add some extra
4392 conversions (because we're now using build_chill_function-call).
4393 * actions.c, decl.c, expr.c, grant.c, parse.y, typeck.c:
4394 Use SET_IN_EXPR in place of IN_EXPR.
4396 * expr.c (build_compare_discrete_expr), ch-tree.h: New function,
4397 with code moved from build_compare_expr.
4398 * expr.c (build_compare_expr): Re-enable compatibility test.

4412 convert, to get the range-checking.
4413 * expr.c (build_chill_pred_or_succ): Fix up rangefail code.
4414 Generate a compile-time message if possible.
4415 (build_compare_expr): Comment out compatibility test - should
4416 not be needed in here. Fix a couple of typos. Add some types
4417 to some build calls.
4419 Sun Mar 20 11:48:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
4421 * decl.c (init_decl_processing): Clean up parameter type
4422 list for __setbitpowerset,
4424 * typeck.c (chill_compatible_classes): Allow the M-reference
4425 to be compatible with the N-value class, with suitable M and N.
4426 * typeck.c (build_chill_slice): Don't smash a void TREE_TYPE.
4427 (We don't need to, and it causes confusion.)
4429 * expr.c (build_compare_expr): Fix thinko. Add save_exprs.
4431 * expr.c (build_compare_expr): Fix a transcription bug
4432 (for converting NULL INSTANCEs). Also #include convert.h.
4434 * expr.c (compare_int_csts): New. Compare INTEGER_CSTs.
4435 Works even if their types have different TREE_UNSIGNED.
4436 * expr.c (finish_chill_binary_op): Moved code dealing with
4437 the comparison operators from here ...
4438 * expr.c (build_compare_expr): ... to new function here.
4439 Also, for discrete types, tries to Do The Right Thing, even for
4440 differing values of TYPE_PRECISION and TREE_UNSIGNED.
4442 * ch-tree.h: Declare new functions.
4443 * typeck.c (valid_array_index_p): Various cleanups,
4444 including using new build_parse_expr.
4445 * parse.y: Use new build_compare_expr.
4447 * inout.c (build_chill_writetext): Handle REFERENCE_TYPE args.
4449 Sun Mar 20 08:54:27 1994 Bill Cox (bill@rtl.cygnus.com)

4461 to get runtime index checking.
4462 * expr.c (build_chill_pred_or_succ): Fix cond tree
4463 to have consistent operand types.
4464 * typeck.c (valid_array_index_p): Change interface to pass
4465 validity conditions back on caller's TREE_LIST. We
4466 cannot link the conditions to anything which a
4467 layout_type routine will expand, since that will occur
4468 before the exception handler is set up.
4469 Change calls to valid_array_index_p also.
4471 Fri Mar 18 14:40:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
4473 * actions.c, except.c, loop.c, tasking.c: Call
4474 build_chill_function_call instead of the C-specific
4475 build_function_call.
4476 * except.c (initialize_exceptions): Fix parmtype of __builtin_setjmp.
4477 * loop.c (top_loop_end_check): Coerce library function arg.
4478 * convert.c, expr.c: Re-write to avoid calls to C-specific
4479 function build_unary_op (e.g. by calling build1 directly).
4481 * typeck.c (chill_equivalent): Change to force failure
4482 for non-matching integral types (even if not ranges).
4484 * typeck.c, ch-tree.h (build_chill_slice): Make non-static.
4485 * expr.c (varying_to_slice): Call build_chill_slice (and not
4486 build_chill_slice_with_length, which does bunches of range
4487 checking and does not allow the length to be zero).
4488 * convert.c (convert): Fix off-by-one error.
4489 * actions.c (chill_expand_array_assignment): Minor cleaning up.
4491 Fri Mar 18 00:12:48 1994 Per Bothner (bothner@deneb.cygnus.com)
4493 * decl.c (init_decl_processing): __lepowerset and __ltpowerset
4494 take *two* pointer parameters, not one.
4495 * satisfy.c (satisfy): Only call the appropriate layout routine
4496 if TYPE_SIZE is 0 (i.e. type hasn't already been laid out).
4497 * typeck.c (build_chill_slice_with_length): Fix Bill's previous fix.
4499 Thu Mar 17 17:29:43 1994 Bill Cox (bill@rtl.cygnus.com)
4501 * expr.c (build_chill_function_call): Give function call the correct
4503 * typeck.c (build_chill_slice_with_length): Restore dynamic range
4504 checking, so it doesn't obscure the CONSTANTness of the length.
4506 Wed Mar 16 17:23:31 1994 Per Bothner (bothner@kalessin.cygnus.com)
4508 * typeck.c (build_chill_slice), expr.c (chill_expand_expr
4509 [case CONCAT_EXPR]): Remove kludge setting slice size upper bound
4510 in TYPE_LANG_SPECIFIC, and restore kludge setting it in MAX_VALUE.
4511 * typeck.c (build_chill_slice): Use TYPE_MAX_VALUE of
4512 array_type if needed for size upper bound of slice_type.
4513 * expr.c (build_concat_expr): Improve calculation of size upper bound.
4515 * typeck.c (valid_array_index_p): Check compatibility using
4517 * typeck.c (build_chill_slice_with_length); For now revert
4518 calling valid_array_index_p on length. (It makes it harder
4519 to realize when the slice is constant length.)
4520 * expr.c (build_chill_indirect_expr): Minor tweak. (This
4521 seems to work around a weird C compiler bug. ??)
4523 * expr.c (build_chill_function_call): Cleanup so it doesn't
4524 call build_function_call (in c-typeck.c).
4525 * typeck.c, expr.c: Use build_chill_function_call instead of
4526 build_function_call (in c-typeck.c).
4528 * parse.y (discrete_mode): Move some of the rules from
4529 non_array_mode into new non-terminal.
4530 (arrayindex): Use discrete_mode (with NAME and TYPENAME) to
4531 avoid some misparses.
4532 * ch-tree.h (SLICE_PTR, SLICE_LENGTH): Removed; unused.
4533 * convert.c (digest_structure_tuple): Add missing parameter.
4534 * decl.c (comptypes): Remove unused prototype.
4535 * decl.c (build_chill_function_type): Handle NULL return_type
4536 correctly (convert to void_type_node).
4537 * decl.c (init_decl_processing): layout boolean_type_node *after*
4538 we've set it's TYPE_MIN_VALUE and TYPE_MAX_VALUE.
4540 Wed Mar 16 16:08:22 1994 Bill Cox (bill@rtl.cygnus.com)

4543 * convert.c (convert): Correct calculation of padding length.
4544 * decl.c (grok_chill_fixedfields): Move ignore_exprs test to
4545 parse.y where it belongs. This permits the removal of a kludge
4546 in make_process_struct.
4547 * lex.l, parse.y: Call to_global_level for several errors. Add
4548 code to output error in only one pass.
4549 * tasking.c (make_process_struct): Delete kludge inserted on

4556 (build_rts_call): Ifdef it out - never used.
4557 (expand_varying_length_assignment): call valid_array_index_p.
4558 rather than validate_varying_array_ref.
4559 * ch-tree.h: Fix prototype for valid_array_index_p.
4560 * expr.c (chill_expand_expr): Call build_chill_array_ref to get
4562 (build_hill_lower, build_chill_upper): Return value now inherits
4563 the novelty of the input parameter.
4564 (varying_to_slice): Use CH_NOVELTY macro rather than calling
4565 chill_novelty directly.
4566 * grant.c (newstring): Make len unsigned and cast xmalloc parameter
4568 (print_integer_type): Pass string value as APPEND's second parameter.
4569 (decode_decl): Pass a boolean expression as print_proc_tail's
4571 (chill_finish_module_code): Make xmalloc's parameter unsigned.
4572 * lex.l: Pass sizes to xmalloc as unsigned ints. Pass second
4573 parameter to in_word_set as unsigned.
4574 * loop.c (build_loop_start): Check top_loop_end_check return value.
4575 * parse.y: Add casts to int for third do_decls parameter, fifth
4576 build_loop_iterator parameter, etc.
4577 * tasking.c (build_receive_case_end): Chack cond_stack before popping.
4578 * typeck.c (validate_varying_array_ref, chill_max_vary_array_index,
4579 valid_array_index): Delete them. They're now unused.
4580 (valid_array_index_p): Add function, call it everywhere that an
4581 array index is checked.
4582 (build_chill_slice): Restore old functionality where varying_to_slice
4583 is called to handle slices of varying arrays, rather than handling
4585 (build_chill_slice_with_range, build_chill_slice_with_length):
4586 Check range limits for TREE_CONST before calling tree_int_cst_lt.
4587 Delete now-obsolete checks of constant indices.
4589 Mon Mar 14 17:26:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4591 * parse.y (modeless_expr): New rule to allow ([...]) and (if...)
4592 to count as untyped_exprs. (This is not really permitted by the
4593 Blue Book, but has been requested by customers.)
4595 Thu Mar 10 10:11:02 1994 Bill Cox (bill@rtl.cygnus.com)
4597 * chill.texi: Document new command-line options.
4598 * expr.c (build_chill_num): Set unsigned parameter for
4599 type_for_size call correctly (unsigned for enums).
4600 * lang.c (lang_decode_option): Add command-line options to
4601 enable/disable runtime range-checking.
4602 * lex.l: Eat more whitespace.
4604 Thu Mar 10 09:41:37 1994 Bill Cox (bill@rtl.cygnus.com)
4606 * Makefile.in: Have rules to make parse.h, y.tab.c and other
4607 derived files. This allows the gcc/configure list of CHILL
4608 files machinery to work.
4609 * ch-tree.h (permanent_allocation): Add a parameter flag.
4610 * decl.c (finish_chill_function, finish_decl): Provide the
4611 new permanent_allocation flag.
4612 (poplevel): Return early, avoid a seg fault.
4613 * lex.l (NORMAL): Replace this whole state with the predefined
4614 INITIAL state. Force compilation state to global level after
4615 compiler directive error - prevents endless loop on error.
4616 (handle_use_seizefile_directive): Rewrite for readability.
4617 (chill_same_grant_file): Reindent.
4618 Generally handle whitespace differently.
4619 * regression.prpt: Print ten PR numbers per line. The report's
4622 Wed Mar 9 09:58:51 1994 Bill Cox (bill@rtl.cygnus.com)
4624 * decl.c (do_decl): Suppress the string-assignment-condition
4625 error - it was too often seen.
4626 * expr.c (expand_chill_expr): In CONCAT_EXPR, when argument has a
4627 runtime-changing length (as in a slice), get the parent array's
4628 allocation size from its type tree.
4629 * typeck.c (build_chill_slice): Support VARYING arrays. Pass
4630 parent array's static allocation size along in the slice type.
4632 Wed Mar 9 08:54:24 1994 Bill Cox (bill@rtl.cygnus.com)
4634 * lex.l (name_type_signal): Avoid dereferencing a NULL TRE_TYPE.
4636 Tue Mar 8 11:51:10 1994 Bill Cox (bill@rtl.cygnus.com)
4638 * expr.c (build_chill_sizeof): Fix typo in error msg, add
4640 * lex.l (name_type_signal): Add debug output.
4641 * parse.y (call): Allow EVENTNAME and BUFFERNAME parameters
4642 to a call, so that SIZE () works on them.
4643 * tasking.c (make_process_struct): Force ignore_exprs non-zero
4644 when processing a SEIZEd PROCESS declaration. This prevents
4645 grox-fixed_fields from returning a NULL, and indirectly protects
4646 the chill_integer_type_node tree from corruption.
4648 Mon Mar 7 19:14:05 1994 Bill Cox (bill@rtl.cygnus.com)
4650 * Makefile.in: Use the 'all' target to build the runtime
4651 library and chillrt0.o.

4654 chill.regress.cron: Move to utils subdirectory.
4655 * expr.c (build_chill_function_call): Mark the INOUT

4657 register. Fixes the execute/inout.ch bug.
4658 * typeck.c (layout_chill_range_type): Restrict it
4659 from complaining about an empty string type's
4662 Mon Mar 7 09:06:39 1994 Bill Cox (bill@rtl.cygnus.com)

4666 Add $(FLAGS_TO_PASS) to sub-make invocations.
4667 * ch_decomment.l, ch_makedepend, chill.patches, printf.c,

4694 * inout.c (build_chill_writetext): Add handling of a REAL.
4695 * lex.l (INITIAL): Remove all code to discard 'header lines'.
4697 * parse.y (optheader): Remove - it's obsolete, as is the
4698 HEADEREL token definition.
4700 Fri Mar 4 09:41:18 1994 Bill Cox (bill@rtl.cygnus.com)
4702 * addtest: Fix suffix removal when suffix is .c186.
4703 * regression.sh: Allow for underscores on PR filenames.
4704 * typeck.c: Check in the rewrite mentioned earlier.
4706 Thu Mar 3 09:42:10 1994 Wilfried Moser (fs_moser at rcsw1h)
4708 * tasking.c (build_process_header): Build a debug structure

4722 range-checking code. Handle reference_type in convert call.
4723 (chill_expand_assignment): Produce an INDIRECT_REF for a

4791 string_assignment_condition for some of it.

4797 name for correctness.
4799 Wed Feb 23 15:07:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4801 New cleaner solution to the following problem:
4802 Chill allows an action to be followed by an ON-handler.
4803 But we don't know if an action has a handler until we've parsed
4804 its end, yet we want to generate extra code to set up an
4805 exception handling contour only if needed. The old solution
4806 would generate code for the action into an rtl sequence, and then
4807 splice in the exception-setup code if we later found we needed it.
4808 This has a few problems (for example it confuses the management
4809 of stack temporaries), and is ugly. Now that the compiler is 2-pass
4810 we have a cleaner solution: In pass 1, we remember which actions
4811 were followed by ON-handlers. In pass 2, we use this information
4812 to generate appropriate code before an action.
4813 * except.c (push_handler, pop_handler): In pass 1, set up data
4814 structures (global_handler_list) to remember if an action has an
4815 ON-handler. In pass 2, digest this information, and setup
4817 * except.c, actions.h (pop_handler): Take an extra int arg.
4818 * except.c (emit_setup_handler): New function, with code (moved
4819 from chill_start_on) to emit code before an action that has a handler.
4820 * except.c (except_init_pass_2): New function.
4821 * parse.y (pass1_2): Call except_init_pass_2 before pass 2.

4823 * parse.y: Invoke POP_UNUSED_ON_CONTEXT and POP_USED_ON_CONTEXT
4824 in pass 1 as well as pass 2.
4825 * parse.y (BEGIN ... END): Re-arrange logic to avoid block_stack
4826 (local to ../stmt.c) getting out of sync.
4827 * actions.c (push_action): Don't need to emit a NOP,
4828 now that we're no longer moving sequences around.
4829 * actions.c (push_action): Call push_handler even in pass one.
4831 Wed Feb 23 11:06:14 1994 Bill Cox (bill@rtl.cygnus.com)

5446 * c-typeck.c (really_start_incremental_init): Save
5447 constructor_elements and (old value of) constructor_stack
5448 on constructor_stack, to allow for nested initializers.
5449 * ch-convert.c (digest_constructor): If we need a varying
5450 array, and have a constructor (for the array elements),
5451 make sure to use convert so that the constructor gets
5452 wrapped in an implicit record constructor.
5453 * ch-decl.c (do_decl): If there is no initializer for a
5454 varying array (or bitstring), create default constructor.
5456 * ch-expr.c (build_chill_lower): Fix thinko for ARRAY_TYPE.

5461 which does the actual work for build_chill_array_ref (which
5462 now just loops over an argument list).
5463 * ch-actions.c, ch-expr.c, ch-inout.c: Use build_chill_array_ref_1
5464 instead of build_chill_array_ref where appropriate.
5465 * ch-actions.c, ch-expr.c, ch-typeck.c: Make operand 1 of a
5466 VARY_ARRAY_REF is a single index, not an index list.
5468 * ch-grant.c (__init_list): Renamed to _ch_init_list, to
5469 avoid a conflict on the Alpha.

5493 'struct ch_class class = chill_expr_class (expr);' to
5494 'struct ch_class class; class = chill_expr_class (expr);'
5495 to work around a bug in /usr/ucb/cc on SunOS4.
5497 Mon Jan 10 18:29:36 1994 Bill Cox (bill@rtl.cygnus.com)
5499 * ch-actions.c (chill_convert_for_assignment): Avoid seg fault.

5518 Convert result to correct class.
5519 * ch-expr.c (build_chill_repetition_op): Preserve CH_DERIVED_FLAG.
5520 Also, fix some bugs for bitstrings (with ranges).
5522 (Patches from Tiemann.)
5523 * ch-convert.c (convert1): New function to force TREE_TYPE.
5524 (convert): Use convert1 where appropriate.
5525 * ch-typeck.c: Formatting change.
5526 * ch-parse.y (build_chill_constructor): Fix thinko.
5528 * ch-expr.c (varying_to_slice): If array is not referable,
5529 call save_expr on it, rather than stabilize_reference.
5530 * ch-satisfy.c (safe_satify_decl, for CONST_DECL):
5531 Don't force value to value class if mode is not explicitly
5532 specified. Also, make sure convert etc is only done once.
5534 Sat Jan 8 16:37:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
5536 * ch-decl.c (build_chill_function_type): Don't call
5537 build_function_type, because it does hash canonicalization,
5538 which once in a while looses badly.
5539 * tree.c (build_function_type): Remove no-longer-needed test
5540 for doing_chill_thang.
5542 * ch-tree.h (CH_DERIVED_FLAG): New flag.

5557 * ch-expr.c (finish_chill_binary_op): Use convert_to_class.
5558 * ch-satisfy.c (safe_satisfy_decl): For CONST_DECL, make sure
5559 DECL_INITIAL gets set to result of convert.
5560 Also, clear CH_DERIVED_FLAG for SYN value.
5561 * expr.c (store_constructor): If a [power]set is exactly one
5562 word long, use single-word move.
5564 Sat Jan 8 08:38:29 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5566 * c-typeck.c (chill_initializer_constant_valid_p): Fix typo.
5568 Wed Jan 5 05:18:46 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5570 * ch-typeck.c (build_chill_slice_with_length): Test that ARRAY is of
5571 ARRAY_TYPE before assuming so. Also, subtract 1 from LENGTH in
5572 computation of SLICE_END.

5576 * ch-expr.c (build_chill_indirect_ref): Handle MODE == NULL_TREE.
5578 * ch-expr.c (fold_set_expr): Handle OP1 == NULL_TREE (which happens
5579 for unary set operations).
5581 * ch-expr.c (build_chill_array_expr): Take new argument FORCE. All
5582 callers changed. All callers changed.
5584 * ch-convert.c (digest_structure_tuple): Handle SELECTED_VARIANT
5585 being NULL_TREE until we've started walking the list of values via
5586 the loop over VARIANTs.
5588 * ch-parse.y (build_chill_constructor): If we see an IDENTIFIER_NODE,
5589 treat it as an enum value (and hence constant). Also, only set
5590 TREE_STATIC if the constructor is indeed constant.
5591 * c-typeck.c (chill_initializer_constant_valid_p): If we see a
5592 VAR_DECL, test the TREE_CONSTANT field of the DECL_INITIAL, don't
5593 recurse on the DECL_INITIAL.
5595 Wed Jan 5 01:24:50 1994 Bill Cox (bill@cygnus.com)
5597 * Makefile.in: Add CHILL to LANGUAGES variable.
5598 * ch-actions.c (check_range): Call build_binary_op instead of
5599 fold, build to get the common types chosen.
5600 (cond_range_exception, cond_overflow_exception,
5601 cond_type_range_exception): Delete, obsolete.
5602 (chill_convert_for_assignment): Enable this, get particular
5603 about when to generate rangecheck code.
5604 * ch-expr.c (build_chill_function_call): Sketch in where to
5605 perform chill_convert_for_assignment on actual parameters.
5606 (build_chill_addr_expr): Correct compiler warning.
5607 * ch-loop.c (build_chill_iterator): Add runtime check for
5608 negative loop step expression.
5609 * ch-tree.h: Add prototype.
5610 * ch-typeck.c (chill_max_vary_array_ref): Correct misunderstanding.
5611 A varying array's length field counts the NUMBER of active array
5612 array entries, not the byte-length of them.
5614 Tue Jan 4 17:57:39 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5616 * ch-decl.c (do_decl): Call `suspend_momenary' if the
5617 converted constructor must live on the permanent_obstack.
5618 * ch-convert.c (convert): When building a new SET_TYPE
5619 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.

5633 * ch-expr.c (build_chill_arrow_expr): Call `mark_addressable'.
5634 (build_chill_addr_expr): Take new argument ERRORMSG.
5635 All callers changed. Also, call `build_chill_addr_expr' where
5636 we used to call `build1 (ADDR_EXPR, ptr_type_node, ...)' since
5637 that now calls `mark_addressable' automagically.
5639 * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.
5640 This is needed because variables may appear in initialization
5641 statements, and their DECL_INITIALs are their values at
5642 initialization time.
5643 * ch-convert.c (digest_structure_tuple,digest_constructor): Changed
5644 to handle VAR_DECLs as initializers.
5646 * ch-convert.c (digest_structure_tuple): Copy elements of INITS so
5647 they aren't destroyed for later use.

5652 parameter for varying_array_ref calculations.
5653 (build_chill_indirect_ref): Prevent seg fault due to syntax error.
5654 * ch-typeck.c (build_chill_slice_with_range): Correct issuance
5655 of bogus error in votrics.
5656 (build_chill_slice_with_length): Change for debug tracability.
5658 Tue Jan 4 02:43:37 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5660 * ch-convert.c (digest_structure_tuple): Fix phasing problem in
5661 handling variant record initializers.
5662 (various places): Change `pop_init_level' calls to match
5663 `push_init_level' wrt implicit variable.
5665 * ch-typeck.c (build_chill_slice): Convert the dynamic max index to
5666 `integer_type_node' before using it in comparisons. FIXME: should
5667 this be done in `chill_max_vary_array_index' by default?
5669 Tue Jan 4 00:24:14 1994 Bill Cox (bill@cygnus.com)
5671 * ch-actions.c: Fix comments.
5672 * ch-parse.y: Define caseaction_flag.
5673 (caseaction): Create new caseaction_flag node at the start,
5674 then free it at the end. Check it before the ELSE code.
5675 (expanded_case_label): Check the flag here. If set in either
5676 place, generate a jump to the end of the case.
5677 * ch-typeck.c (build_chill_slice_with_length,
5678 build_chill_slice_with_range): Add lots of compile-time
5679 parameter range checking.
5681 Mon Jan 3 21:49:04 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5683 * ch-convert.c (digest_structure_tuple): Call `push_init_level' with
5684 implicit==0 everywhere, not 1.
5685 (digest_constructor): Ditto.
5687 * ch-actions.c (check_range): Permit limits to be NULL_TREE.
5688 Also, hack out some dead code.
5689 * ch-typeck.c (build_chill_slice): Check varying and non-varying
5690 slice constructs for range failures.
5691 (build_chill_slice_with_range): Reindented, but not changed.
5693 * ch-typeck.c (chill_max_vary_array_index): New function.
5694 * ch-expr.c (chill_expand_expr): Call it.
5696 * ch-decl.c (var_data_id, var_length_id): New variables.
5697 (init_decl_processing): Initialize them. All calls to
5698 get_identifier (VAR_LENGTH or VAR_DATA) are now replaced
5699 by references to these variables. This simplifies the code
5700 w/o obscuring anything.
5702 Mon Jan 3 21:24:44 1994 Bill Cox (bill@cygnus.com)
5704 * c-typeck.c: Fix comment.
5705 * ch-actions.c (chill_expand_assignment): Error assigning to
5706 READONLY location. (PR_3903) Pass filename, linenumber
5707 to setbitpowerset runtime routine.
5708 * ch-decl.c (init_decl_processing): Add filename, linenumber
5709 parameters to setbitpowerset prototype.
5710 * ch-expr.c (build_chill_function_call): Error when passing a
5711 READonly location as a LOC or INOUT parameter.
5712 * ch-parse.y (mode): Correct code marking type as readonly.
5714 Mon Jan 3 19:03:55 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5716 * ch-actions.c (chill_expand_assignment): Disable code that defeats
5717 building varying array references.
5718 * ch-expr.c (chill_expand_expr): Add rangecheck code to
5719 VARY_ARRAY_REF case.
5720 * ch-typeck.c (build_chill_array_ref): Don't call an `expand_'
5721 function (in this case, `validate_varying_array_ref') when we're
5722 doing a `build_' operation.
5724 * ch-typeck.c (validate_varying_array_ref): Simplify interface
5725 since INDEX parameter can never meaningfully be an INDEXLIST.
5726 * ch-actions.c (expand_varying_length_assignment): Caller changed.
5728 Mon Jan 3 07:29:45 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5730 * ch-typeck.c (build_chill_cast): Set TREE_CONSTANT on NOP_EXPRs.
5731 * ch-convert.c (digest_structure_tuple): Switch to permanent_obstack
5732 if we need to build a CONSTRUCTOR for a SET_TYPE initializer.
5733 (digest_structure_tuple): If TREE_VALUE (VALUE) == NULL_TREE, don't
5734 call CH_COMPATIBLE or try to convert it to TREE_TYPE (FIELD). This
5735 can happen when constructors are output incrementally.
5736 * c-typeck.c (initializer_constant_valid_p): Handle SET_TYPEs.
5737 * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
5740 Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5742 * ch-convert (digest_structure_tuple): Handle SET_TYPEs. Also, call
5743 `convert' so we can handle INSTANCE types (and other anomolies)
5746 * ch-convert.c (digest_structure_tuple): Fixed variant
5747 structure initialization. Also fixed a typo (TYPE_NAME
5748 was being used on a FIELD_DECL instead of DECL_NAME).
5749 * c-typeck.c (initializer_constant_valid_p): Pass missing
5750 ENDTYPE argument on recursive call.
5751 (set_init_field): New function, needed by ch-convert.c change above.
5753 * ch-decl.c (layout_chill_variants): Added a FIXME next to an
5754 almost certain typo.
5756 * ch-expr.c (build_chill_arrow_expr): Call `build1' and set
5757 TREE_CONSTANT for static references.
5758 * ch-except.c (chill_start_on): Change calls to
5759 `build_unary_op' (which is C-specific) to `build_chill_arrow_expr'
5760 which has CHILL semantics.
5761 * ch-convert.c (convert): Ditto (albeit in some disabled code).

5766 TREE_CODE of DECL in case it's altered by actions in the switch.
5768 * ch-satisfy.c (satisfy): Undo abort added earlier on 1 Jan. CVS log
5769 mentions where to find code that triggers this case.
5771 * ch-actions.c (adjust_parm_or_field): Handle CONSTRUCTORS here as
5774 * ch-convert.c (digest_structure_tuple): Push to permanent_obstack if
5775 we're dealing with a CONSTRUCTOR that is TREE_PERMANENT.
5776 (digest_constructor): Ditto.
5778 Sat Jan 1 10:29:19 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5780 * ch-parse.y (handleraction,resultaction,assignaction,call): Modified
5781 so that CONSTRUCTORS are properly handled before being used.
5783 * ch-convert.c (chill_start_init): New function. All callers to
5784 `start_init' changed to call this function instead.
5785 (digest_struct_tuple): Defend against initialization machinery
5786 mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
5787 IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
5788 needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
5789 can be refered to throughout the compilation unit. Also remove an
5790 extraneous call to `process_init_element' erroneously added to the
5791 variant record sub-loop.
5792 (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
5793 CONSTRUCTORS of SET_TYPE.
5794 * ch-parse.y (build_chill_constructor): Refix typo. Also set
5795 TREE_STATIC if at top level.
5797 * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
5798 TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
5799 should have been called.
5801 * ch-convert.c (digest_struct_tuple): Restore code which tracks
5802 field initializations so that the compiler can deduce what variant
5803 initializations to assume.
5805 * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
5806 when we push into a scope that has a DECL with a CONSTRUCTOR as its
5809 * ch-parse.y (build_chill_constructor): Change the name of the
5810 parameter to something more meaningful. Fix typo. Also, handle case
5811 where element is an untyped CONSTRUCTOR.
5813 * ch-except.c (finish_handler_array): Set TREE_CONSTANT on
5814 constant ADDR_EXPRs.
5815 (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT
5816 on JBUF_REF (instead of calling `build1' which does not).
5818 * ch-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
5820 * ch-typeck.c (chill_expand_tuple): Deleted.
5821 * ch-parse.y (primval rule): Don't call `chill_expand_tuple';
5822 instead, use initialization machinery for CONSTRUCTORS that
5824 * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
5825 that are created here.
5826 * ch-satisfy (satisfy): Abort in case we would have called
5827 chill_expand_tuple. FIXME: some other code is needed here,
5828 but I don't know what yet.
5830 * ch-parse.y (build_chill_constructor): New function to
5831 propagate TREE_CONSTANT bits to CONSTRUCTORS.
5832 (untyped_expr rule): Use it.
5833 (primval rule): Use it.
5835 * ch-decl.c (do_decl): Call `finish_init'.
5836 * ch-convert.c (convert): If we spontaneously create a CONSTRUCTOR in
5837 this function, make sure the initialization machinery is set up.
5839 * ch-convert.c (digest_structure_tuple, digest_constructor): Add
5842 Fri Dec 31 11:31:01 1993 Michael Tiemann (tiemann@blues.cygnus.com)
5844 * ch-grant.c (chill_finish_module_code): Mark ADDR_EXPR built by hand
5845 as being TREE_CONSTANT. Otherwise it gets bounded by the initializer
5848 * ch-decl.c (do_decl): Change in CONSTRUCTOR handling due to...
5849 * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
5850 rewritten to work with GCC's initialization code. The basic change
5851 was to keep the initializers in sync with the initialization
5852 machinery that `process_init_element' imposes. Both of these
5853 functions now return `void'.
5854 * ch-convert.c (convert): Changed calls to `digest_...' functions.
5856 FIXME: the code handling UNION_TYPE (and variant records) has not

5861 * ch-lex.l (convert_number): Output the converted number if

5866 Fri Dec 31 13:17:48 1993 Bill Cox (bill@cygnus.com)
5868 * ch-parse.y: Cleanup handling of RETURN actions, to distinguish
5869 a RETURN without a value (which cannot have an exception
5870 handler) from a RETURN with a value (which can). Eliminate
5871 some shift/reduce and reduce/reduce conflicts.
5873 Thu Dec 30 17:42:32 1993 Michael Tiemann (tiemann@blues.cygnus.com)
5875 * ch-inout.c (build_chill_writetext): Deal with 2 cases where
5876 types returned from `type_for_size' are not expected. FIXME.
5877 * ch-decl.c (init_decl_processing): Mark `char_type_node' unsigned.
5878 This is required when range checking is enabled.
5880 Thu Dec 30 14:28:25 1993 Bill Cox (bill@rtl.cygnus.com)
5882 DELAY CASE works now.
5883 * ch-decl.c (init_decl_processing): Move rest of tasking-related

5903 failed full regression testing.
5904 * ch-lex.l (name_type_signal): Add debug output.
5905 * ch-parse.y (structured_variable): Add a debug variable.
5907 Wed Dec 29 02:05:51 1993 Bill Cox (bill@rtl.cygnus.com)

5914 DELAY actions work now.
5915 * ch-decl.c: Correct spelling in comments.

5919 * ch-expr.c (build_chill_indirect_ref): Prevent a syntax error from
5920 becoming a seg fault.
5921 * ch-grant.c: Correct a comment.
5922 * ch-loop.c: Delete/correct comments.
5923 * ch-parse.y (delaycaseaction): Add push/poplevel calls. Turn 'sorry'
5924 into rough draft of actual code.
5925 (delayaction): Don't make a new scope here, use get_unique_identifier
5927 (locdec): process event decls here, too.
5928 (mode): Add code to forbid READonly EVENT and BUFFER decls. Delete
5929 code which required EVENTs and BUFFERs to be declared at global scope.
5930 (simple_name_string): Add an EVENTNAME.
5931 * ch-satisfy.c (safe_satisfy_decl): Prevent a syntax error from
5932 becoming a seg fault.
5933 * ch-tasking.c (tasking_setup): Add the event queue's max. length
5934 as the 'entry_point' parameter in the list.
5935 (build_receive_case_start, build_receive_case_label): Defer
5936 calling runtime routine until we know whether we have a signal
5937 or a buffer to wait for.

5946 * gcc.c (CHILL SPECS): Delete references to -M -MM -MD -MMD
5947 options. Delete C-specific defines. Disable piping from
5948 pre-processor to cc1chill (even if -pipe is specified), since cc1chill
5949 rewinds its input for its second pass. Piping still works
5950 from cc1chill to as.
5952 Thu Dec 23 12:31:55 1993 Bill Cox (bill@rtl.cygnus.com)
5954 * ch-tasking.c (decl_tasking_code_variable): Assure that the
5955 tasking_code variable is allocated on the permanent obstack.

5957 queue length (passed as the entry_point parameter).
5958 Other changes to variable names to increase 'self-documentation'
5959 the only kind GNU CHILL will get, for a while..
5961 Wed Dec 22 10:46:31 1993 Bill Cox (bill@rtl.cygnus.com)
5963 * ch-decl.c (do_seize): Delete - it's unused. Fix comments.
5964 * ch-loop.c (build_chill_iterator): Convert BY expression
5965 so loop involving a SET works. Additional errors generated
5966 for numbered SET expression as start or end expression.
5967 * ch-tree.h: Prototypes for future DELAY functions.
5968 * ch-typeck.c: Standard indentation.
5970 Tue Dec 21 15:30:57 1993 Per Bothner (bothner@kalessin.cygnus.com)

5987 * ch-tree.h (CH_EQUIVALENT): Re-defined to use chill_equivalent.
5989 * dbxout.c (dbxout_type): Output the type attribute "@S;" to
5990 distinguish a string from a char array, and to distinguish a
5991 bitstring from regulat (power)set. (Needed for Chill.)
5992 * dbxout.c (dbxout_type): Only check for baseclasses in
5993 type.binfo is a vector. (It is used in Chill for tagged unions.)
5995 Fri Dec 17 09:56:07 1993 Bill Cox (bill@rtl.cygnus.com)
5997 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,

6013 if they're mixed in the same receive case.
6014 (process_buffer_decl): Renamed from build_buffer_decl.
6015 * ch-tree.h: Fix prototypes.
6016 * ch-typeck.c (smash_dummy_type): Handle all four kinds of LANG_TYPE

6031 Tue Dec 14 15:41:32 1993 Per Bothner (bothner@kalessin.cygnus.com)
6033 * ch-decl.c (push_scope_decls): Re-arrange so that normal
6034 (non-seize) declarations are proclaim_decl'd *before* we
6035 handle the ALIAS_DECLs for seizes. The advantage is
6036 that we can now test for (an approximation) to the
6037 'seizeable' concept, thus avoiding duplicate definitions
6038 when a module has both GRANTs and SEIZE ALL.
6040 * ch-expr.c (build_chill_arrow_expr): No longer re-write
6041 addr-of-conversion to pointer-conversion-of-addr.
6042 * ch-expr.c (build_chill_addr_expr): Re-write to just use

6049 * ch-tree.h (chill_root_resulting_mode): Fix typo (missing '_').
6051 * ch-expr.c (finish_chill_binary_op): Use CH_ROOT_RESULTING_MODE
6052 macro (which works on expressions), rather than CH_RESULTING_MODE
6053 (which works on modes, and isn't quite correct).
6054 * ch-tree.h (CH_IS_BOUND_REFERENCE_MODE): New macro.
6055 * ch-typeck.c (chill_read_compatible, chill_compatible):
6056 Use the new macro, which handles NEWMODEs of PTR correctly.

6058 dynamic-length array (and string) types (e.g. slices).
6059 * ch-typeck.c (chill_root_mode): If the mode has a Novelty,
6060 just return it as is. (This is still not 100% correct for
6061 NEWMODE of RANGEs, but is close enough.)

6085 * ch-decl.c (print_lang_identifier): Delete code
6086 to print buffer size - it's no longer kept here.
6087 * ch-parse.y (expand_send_buffer): Renamed from
6089 (locdec): Enable building of a buffer decl.
6090 (optresultspec, optresultattr): Add optional
6091 result attributes such as LOC. Semantics
6093 * ch-tasking.c (expand_send_buffer): Renamed.
6094 * ch-tree.h (build_send_buffer): Renamed.

6179 * ch-decl.c (proclaim_decl): Allow duplicate definitions
6180 of set elements of similar set modes.
6182 * ch-parse.y (caseaction): Call language-independent
6183 expand_start_case rather than c_expand_start_case (which
6184 doesn't allow chars or booleans).
6186 Sat Dec 4 22:16:19 1993 Bill Cox (bill@rtl.cygnus.com)

6738 * ch-parse.y (handleraction): Add return_memory action.
6739 * ch-typeck.c (chill_similar): Allow a void_type
6740 to be similar to anything. This makes allocate_memory

6768 * ch-satisfy.c (safe_satisfy_decl): Satisfy the hidden tasking
6769 code variables associated with a process or signal.
6770 * ch-tasking.c (build_gen_inst, build_gen_ptype): Use the decl's
6771 tasking_code_decl pointer, rather than trying to look it up

6783 generate_tasking_code_variable calls, plus a little glue.
6784 (push_extern_process): generate tasking_code_variable as local
6785 static variable, point the process' function_decl at it for later
6786 reference by build_start_process.
6787 (print_mode): Use CHILL upper-case convention to print modes.
6788 * ch-lex.l: Must initialize tasking-related trees to NULL at start
6789 of each pass, or we lose the fact that the user did or did not
6790 specify a value for each of them.
6791 * ch-parse.y (check_end_label, action, exceptlist): Only output
6792 error message in pass 1.
6793 (sendaction): Add comments.

6796 easier non-symbol-table access later.
6797 * ch-tasking.c (generate_tasking_code_variable): Do work in both
6798 passes, using do_decl so we can pass the pass 2 value of the
6799 process_type or signal_code to it. Only update the process_type
6800 if the incoming pointer isn't null and pass == 2. Use a new
6801 parameter to know whether to include an init expression.
6802 (build_process_header): Attach tasking-code_variable to process
6803 function_decl for easy access later, not through the hash table.

6818 generation for decls to not use DECL_ASSEMBLER_NAME.
6819 * ch-decl.c: Set DECL_ASSEMBLER_NAME to DECL_NAME.
6820 This matches C, and allows dbxout to emit proper user-level names.
6821 (It would be cleaner to fix dbxout to use DECL_NAME ...)
6822 * ch-decl.c (outer_decls): New global list of the decls granted
6823 into the outer scope.
6824 (pop_module): Change code that grants into outer scope accordingly.

6840 * ch-expr.c (finish_chill_binary_op): Convert TRUNC_DIV_EXPR
6841 to RDIV_EXPR if an operand is floating. (This functionality
6842 got dropped when hacking finish_chill_binary_op).
6844 * ch-actions.c (build_chill_case_expr): Set type to NULL_TREE.
6845 not error_mark_node.
6846 * ch-actions.c (chill_expand_assignment): Allow such borderline
6847 constructs as: LHS OR:= [X].
6848 * ch-convert.c (convert): Hande CASE_EXPR (and COND_EXPR)
6849 with unknown (NULL_EXPR) type, not just CONSTRUCTORS.
6850 * ch-decl.c (do_decl): Remove CONSTRUCTOR kludge.
6851 * ch-typeck.c (chill_compatible): Allow expr to have NULL mode
6852 if it's a CASE_EXPR or COND_EXPR (and not just CONSTRUCTOR).

6866 commented-out code as example for assignment of module address to its
6869 Sun Oct 17 15:16:54 1993 Bill Cox (bill@cygnus.com)
6871 * ch-convert.c: Move semicolon to separate line - easier to see.
6872 * ch-decl.c (do_decl): Handle untyped_expr initializers by
6873 simply using the variable's declared type - no compatibility
6874 check can be made if the expression has no type.
6875 * ch-expr.c (expand_packed_set): Fix endless loop - increment
6877 (fold_set_expr): Fix two other endless loops by passing
6878 correct parameters to unpack_set_constructor.

7097 * ch-typeck.c (conflate_singleton_strings): New global.
7098 * ch-typeck.c (chill_similar): If conflate_singleton_strings is

7110 Also, call save_expr on RHS if a multiple assignment.

7112 stabilize_reference on RHS.
7113 * ch-typeck.c (build_chill_modify_expr), ch-tree.h: Remove

7125 * ch-satisfy.c (satisfy): Don't gag on string_index_type_dummy,
7126 * ch-tree.c (build_string_type): Pass string_index_type_dummy as
7127 the parent type of the index range.
7128 * ch-typeck.c (layout_chill_range_type): Recognize and handle
7129 string_index_type_dummy - specifically allow an empty range.
7131 Wed Sep 29 13:36:23 1993 1993 Bill Cox (bill@cygnus.com)
7133 * ch-convert.c (convert_to_reference): Check for loc-identity
7134 mismatches correctly (and remove one of those chill_compatible
7136 * ch-decl.c (decl_tasking_code_var): New function, called from
7137 push_extern_process and push_extern_signal.
7138 * ch-parse.y (end_function): Delete parameter. Check current_function_decl
7139 whether it's actually a process, and whether it has parameters.
7140 Make Michael's change simplifying the pass 2 test, preventing a seg
7142 (procedure, process): Change calls to end_function, remove
7143 code saving value from build_process_header. Delete redundant chill_
7144 phrases from some function calls.
7145 * ch-tasking.c: Remove some redundant _chill phrases from function
7147 * ch-tree.h: Remove some redundant _chill phrases from function
7148 names. Add the CH_VARYING_ARRAY_TYPE macro, call it from
7149 all relevant places.
7150 * ch-typeck.c: Use the new macro. Cast TREE_CODEs to chill_tree_code.
7152 Wed Sep 29 13:07:43 1993 Per Bothner (bothner@kalessin.cygnus.com)

7156 with a recursive convert call.
7157 * ch-decl.c (do_decl): Add missing compatibility-checking
7158 of initializer (don't depend on convert).

7162 * ch-tree.h (CH_LOCATION_P): New macro.
7163 * ch-typeck.c (layout_chill_range_type): Fix call to
7164 type_for_size, when figuring out a defaulted parent type.
7165 * ch-expr.c (build_chill_lower, build_chill_sizeof): Check
7166 for TREE_CODE_CLASS != 't' rather than == 'd'.
7167 * ch-expr.c (build_chill_function_call): Use CH_LOCATION_P
7168 to check for location, rather than TYPE_CODE_CLASS == 'd'.
7170 * ch-tree.c (build_string_type): Make 2-pass safe. Also,
7171 change parameter to be length, not index type.
7172 * ch-parse.y (mode2), ch-expr.c (build_concat_expr), ch-lex.l
7173 (build_chill_string): Modify callers of build_string_type accordingly.
7174 * ch-lex.l (check_newline): Don't look for # directive inside a
7176 * ch-grant.c (grant_array_type): Make more robust for char-
7177 and bit-strings (allow non-constant sizes). Change parameters
7178 and return types. (raw_decode_mode): Use grant_array_type
7179 for bitstrings. (otherwise): Fix grant_array_type callers.
7181 Mon Sep 27 16:57:57 1993 Per Bothner (bothner@kalessin.cygnus.com)
7183 Remove changes of Sep 15.
7184 * ch-tree.h (CH_SINGLETON_DOMAIN): Removed.
7185 * ch-typeck.c (chill_similar): Don't allow a singleton
7186 powerset to be similar to its domain.
7187 * ch-convert.c (convert_to_boolean): Don't convert a singleton
7188 SET_TYPE constructor to a Boolean.
7190 * ch-actions.c (chill_expand_assignment): Handle IN_EXPR on
7191 LHS of assignment, which is what we're current (temporarily?) using.
7193 Mon Sep 27 06:01:57 1993 Bill Cox (bill@rtl.cygnus.com)
7195 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
7196 ch-grant.c, ch-inout.c, ch-parse.y, ch-satisfy.c,
7197 ch-tasking.c, ch-tree.c, ch-tree.h, ch-typeck.c:
7198 -Wall cleanup. Add prototypes where missing.
7199 Delete unused variables. Cast uses of tree_codes
7200 to chill_tree_code, which they are.
7202 Sun Sep 26 13:09:57 1993 Bill Cox (bill@rtl.cygnus.com)
7204 * ch-decl.c (do_decl): Save initializer in pass zero
7206 * ch-lex.l: Fix comments, indentation.
7207 * ch-parse.y: Standardize error messages to use
7208 uppercase for CHILL keywords rather than quoting them.
7209 Suggestion from docs department.
7210 * ch-tasking.c: Pervasive changes to get processes to
7212 * ch-tree.h: Delete prototypes for functions whic
7213 I made static inside ch-tasking.c.
7215 Sun Sep 26 02:40:02 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7217 * ch-lex.l (yywrap): Call `check_newline' in case the file
7218 started with a line directive.
7220 Sat Sep 25 13:54:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
7222 * ch-decl.c: Expand pre-amble comment.
7223 * ch-decl.c (struct scope, push_module): Use new field
7224 tail_chain_module to build child-module list in order.
7225 (Just to make compiler debugging a little less confusing.)
7227 * ch-decl.c (struct scope): New field weak_decls.
7228 * ch-decl.c (find_implied_types): New interface. Now pre-pend
7229 new enum types to a given input list. This makes it easier to
7230 avoid duplicates, which should at least be more efficient.
7231 Also, handle FUNCTION_DECL.
7232 * ch-decl.c (bind_saved_names): Removed. Distribute its
7233 functionality over new functions (push_scope_decls, pop_scope_decls,
7234 build_implied_names, bind_sub_modules). The goal (which seems to
7235 have been more-or-less attained) was to fix weak name handling.
7236 * ch-decl.c (poplevel): Use new function pop_scope_decls.
7238 * ch-tasking.c (build_signal_struct, build_tasking_message_type):
7239 Use build_decl directly, rather than grok_chill_fixedfields
7240 (which depends on ignore_exprs and has more overhead).
7241 * ch-tasking.c (build_signal_struct): Construct the type
7243 * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
7244 than build_array_ref (which does C-specific "optimizations").
7245 (Hence move my_build_array_ref up earlier in the file.)
7247 Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7249 * ch-tasking.c: Declare static variable `void_ftype_void'.
7250 (chill_tasking_init): Initialize `void_ftype_void' here.
7251 (build_tasking_struct): Use, don't declare `void_ftype_void'.
7252 (generate_tasking_code_variable): Call `do_decl', not
7253 `decl_temp1' to declare TASKING_CODE_NAME.
7254 (tasking_setup): Drop into 1-pass mode so that all
7255 tasking-related declarations are installed in the global
7256 scope. Use correct CHILL types for initializers (since
7257 ptr_type_node doesn't have the right meaning for CHILL).
7258 Also, call `do_decl' instead of `decl_temp1' for
7260 (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
7261 `chill_finish_compile' in sync between passes.
7263 * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
7264 declarations on pass zero. Keep obstacks in sync, and always
7265 call `finish_decl' for pass zero declarations.
7266 (push_chill_extern_function): Keep obstacks in sync, and always
7267 call `finish_decl' for pass zero declarations.
7268 (build_enumerator): Ditto.
7269 (grok_chill_variantdefs): Change PASS test to exclude only
7271 (finish_struct): Ditto.
7272 * ch-expr.c (build_chill_component_ref): Ditto.
7273 (build_chill_binary_op): Ditto.
7274 * ch-tree.c (build_powerset_type): Ditto.
7275 (build_bitstring_type): Ditto.
7276 * ch-typeck.c (build_chill_range_type): Ditto.
7277 (build_chill_struct_type): Ditto.
7279 * ch-decl.c (build_chill_exception_decl): Clarify reasons for
7280 extra pushing and popping of obstacks.
7282 * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
7283 on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
7285 * ch-grant.c (chill_finish_compile): Clear out both
7286 MODULE_INIT_LIST and TASKING_LIST if either contains stuff
7289 * ch-parse.y (rccase_label): Add NAME rules so that pass one
7290 works w/o knowing we're parsing a signal. Simplify SIGNALNAME
7291 rules since we only get SIGNALNAME tokens in pass two.
7292 (sendaction): Ditto.
7293 * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
7294 BUFFERNAME on pass two. The grammar now handles this.
7295 * ch-decl.c (lookup_remembered_decl): Deleted.
7297 Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
7299 * ch-decl.c (lookup_remembered_names): Removed. It was being
7300 misused in ch-lex.l.
7301 * ch-lex.l (name_type_signal): Revert last change. Basically,
7302 we cannot use the C typedef/variable name trick in CHILL, due
7303 due to the language's 2-pass nature.
7304 * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
7306 * ch-tree.h (lookup_remembered_name): Comment out the prototype.
7308 Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7310 * ch-decl.c (do_decl, push_chill_extern_function): Change pass
7311 checks so the pass == 0 case is handled for built-in types.
7312 (push_modedef): Add check for error_mark_node.
7313 (lookup_remembered_decl): New function.
7314 (pushlevel, poplevel) Change pass checks.
7315 (pushdecl): Check type as well for NULL.
7316 (build_enumerator): Handle pass == 0 case.
7317 * ch-lex.l: Use lookup_remembered_decl to get lastiddecl
7319 * ch-parse.y: Set pass to zero to indicate initial decl processing.
7320 Replace NAME references with SIGNALNAME references.
7321 (startaction): Only check copy number if not ignoring actions.
7322 Always call build_chill_start_process.
7323 (optstartset): Don't lookup the instance name.
7324 * ch-tasking.c (generate_tasking_code_variable): Replace
7325 do_decl call with decl_temp1 call.
7326 (build_chill_start_action): Check for ignore_actions here.
7327 (build_tasking_message_type): Layout the type.
7328 (rc_state_type): New structure to keep nested receive-case
7330 (build_chill_receive_case_start, build_chill_receive_case_end):
7334 Fri Sep 24 04:19:15 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7336 * ch-tasking.c (build_chill_receive_case_start): `namedecl'
7337 should be a _DECL, not an IDENTIFIER_NODE.
7339 Thu Sep 23 18:18:24 1993 Per Bothner (bothner@kalessin.cygnus.com)
7341 * ch-decl.c (find_implied_types): Handle VAR_DECLs.
7343 * ch-decl.c (print_lang_identifier): Print IDENTIFIER_OUTER_VALUE.
7344 * ch-actions.c (chill_expand_result): Allow value-less RETURN.
7345 * ch-expr.c (resolve_component_ref): Recognize error_mark.
7347 * ch-convert.c (digest_constructor): Handle a nested powerset tuple.

7349 * ch-typeck.c (chill_similar): Repeatedly get parent modes
7350 of ranges, not just once.
7351 * ch-typeck.c (chill_root_resulting_mode), ch-tree.h: New function.
7352 * ch-typeck.c (layout_chill_rang_type): Re-do type-checking
7353 to follow Blue Book better (check for Compatibility).
7355 * ch-tree.h (CH_ROOT_RESULTING_MODE): New macro.
7356 * ch-lex.l (use_seizefile_name, current_seizefile_name), ch-tree.h:
7357 New variables. The latter replaces in_seizefile.
7359 Changes to store in the new DECL_SEIZEFILE field each seize
7360 ALIAS_DECL the name in the most recent use_seize_file directive.
7361 (This requires that use_seize_file directives written to the
7362 grant file be written before the SEIZEs that need it.)
7363 Allow clashing declarations granted into the global scope
7364 (produce a warning), but remember the seizefile case from
7365 (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
7366 The a SEIZE will select the granted decl that matches its
7367 DECL_SEIZEFILE (in other words: grants from the most recent
7368 use_seize_file will be preferred).
7369 * ch-tree.h (DECL_SEIZEFILE), ch-tree.def: New macro.
7370 * ch-tree.h (global_value, IDENTIFIER_GLOBAL_VALUE): Renamed
7371 to outer_value, IDENTIFIER_OUTER_VALUE.
7372 Changes to cause the use_seize_file directives to be written
7373 out in order as they're seen in source.
7374 * ch-lex.l (files_to_seize, next_file_to_seize, last_file_to_seize):
7375 Changed to have type TREE_LIST of pointer to IDENTIFIER_NODE.
7376 * ch-lex.l (handle_use_seizefile_directive): Modify appropriately.
7377 Don't call grant_use_seizefile.
7378 * ch-lex.l (mark_use_seizefile_written): New function.
7379 * ch-grant.c (decode_decl): Write out use_seize_file directive,
7380 if needed, before writing a seize declarations.
7381 * ch-decl.c (pop_module): Handle decls granted into the global
7382 module specially, setting IDENTIFIER_OUTER_VALUE.
7383 * ch-decl.c (lookup_name_for_seizing): Check IDENTIFIER_OUTER_VALUE.
7385 Thu Sep 23 19:05:37 1993 Bill Cox (bill@cygnus.com)
7387 * ch-decl.c (push_chill_extern_process): Delete unused variables,
7388 declare the process' tasking_code variable as external.
7389 * ch-parse.y (process): Force ignore_exprs to FALSE while parsing
7391 * ch-tasking.c (sigdef): Move resetting of quasi_signal from here
7393 * ch-tree.h: Add prototype.
7394 * expr.c (store_constructor): Emergency first-aid. Rewrite later.

7398 * ch-expr.c (build_chill_function_call): Move possible call to
7399 chill_start_module_code until we know we're not calling a builtin.
7400 * ch-decl.c (save_expr_under_name): Use pushdecllist,
7401 not proclaim_decl (which provide for popping the decl).
7402 * ch-parse.y (optname): Also allow TYPENAME.
7404 Thu Sep 23 09:18:35 1993 Bill Cox (bill@cygnus.com)
7406 * ch-decl.c (print_lang_decl): Make weak name output more standard.
7407 (print_lang_identifier): Make signal-data flag output more standard.

7409 push_chill_extern_function.
7410 (push_syn_decls, fixup_unknown_type, chill_modes_equiv):
7411 Standardize function header layouts (Makes the tcov script

7432 * ch-grant.c (print_struct): Add missing loop for tag_list.
7433 (print_struct): Look for variant fields by checking for a
7434 UNION_TYPE, not a NULL name, since we must use a dummy name.
7435 * ch-parse.y (structured_variable): Various fixing.
7436 * ch-decl.c (shadow_record_fields): Rename arg decl -> struct_val.
7438 * ch-satisfy.c (safe_satisfy_decl): Disable copying of modes
7439 for NEWMODE (and hence novelty checking), until we figure out
7442 * ch-except.c (finish_handler_array): Use null_pointer_node,

7454 New functions. Handle 2-pass and variant records.
7455 * ch-parse.y (primval DOT name): Use instead of build_component_ref.

7463 Use it to replace locnamelist, synnames, and modenames.
7464 * ch-parse.y: Re-write parsing of variant records.
7466 * ch-decl.c (grok_chill_variantdefs): Now return a FIELD_DECL
7467 rather than just its type.

7469 Change callers appropriately.
7471 * ch-tree.h (TYPE_TAG_VALUES): Add an extra level of TREE_LIST,
7472 to support multiple tag fields.
7473 * ch-grant.c (print_struct), ch-decl.c (layout_chill_variants):
7474 Support multiple tag fields.
7476 * ch-convert.c (remove_tree_element, digest_structure_tuple):
7477 New functions, to digest structure tuples, without calling the

7500 (quasi_locdec): Call build_chill_reference_type to defer
7501 doing the type's layout.
7502 (processpar): Use paramnamelist, but reformat it into a
7503 list of identifiers in pass 2, so a processpar is the same
7504 structure in both passes.
7505 (locdec): Call build_chill_reference_type to defer doing the
7507 * ch-tasking.c (generate_tasking_code_variable): Call do_decl to

7510 doing the type's layout.
7511 (build_process_header): New code to call make_process_struct.
7512 New pass-2 code to make a PARM_DECL for start_chill_function.
7513 Pass a void_type_node, not a NULL_TREE for an empty list.
7514 Get input for shadow_record_fields from current_function_decl.
7515 (build_buffer_decl): Call do_decl not decl_temp1.
7516 * ch-typeck.c: Reindent to standards.

7519 Mon Sep 20 12:00:24 1993 Per Bothner (bothner@kalessin.cygnus.com)
7521 * ch-typeck.c (classify_chill_expr): An expression with a
7522 REFERENCE_TYPE still has VALUE class, even if an ADDR_EXPR.
7523 * ch-actions.c (adjust_parm_or_field):, ch-tree.h: Change last
7524 parameter, so we can reliably recognize LOC parameters.
7525 * ch-tasking.c, ch-expr.c: Change callers appropriately.
7527 Sun Sep 19 22:26:25 1993 Per Bothner (bothner@kalessin.cygnus.com)

7548 Fri Sep 10 12:23:41 1993 Wilfried Moser (fs_moser@cygnus.com)
7550 * Makefile.in: Change installation of the chill script. gcc will
7551 be called always with the full path. That made problems when
7552 somebody was using chill but didn't have the installation

8424 for all preferedined types.
8425 * ch-lex.l (init_lex): Upper case all RIDs, so grantfiles

8570 way I allocated the shadow_list on an obstack was too fragile,

9979 function is no longer visible,, can't get it using

9983 to end of parameter types list.
9985 * ch-grant.c (chill_start_module_code): Make sure module

10062 Sat Apr 10 09:55:50 1993 Bill Cox (bill@rtl.cygnus.com)
10064 * ch-actions.c (build_chill_case_expr): Added from ch-parse.y.

10074 Sat Apr 10 01:10:51 1993 Per Bothner (bothner@rtl.cygnus.com)
10076 * ch-parse,y (in_pseudo_module): New variable. Try if we're

10091 yylex() recursively.

10156 * ch-decl.c (push_parms): Use new massage_param_node().

10203 Fri Apr 2 21:55:14 1993 Per Bothner (bothner@rtl.cygnus.com)
10205 Major re-write of New module/seize/grant stuff.
10206 Now, a grantfile is a spec module and contains all the
10207 top-level declarations of the granting module, not just
10208 those that are granted. It also contains explicit grant
10209 statments naming those declared names that are granted.
10210 It also has seize statements and use_seize_file directives
10211 to correctly handle transitive dependencies.
10213 * ch-parse.y: Change to allow multiple modules per source file.
10214 Allow spec modules (including quasi definitions) as well as
10216 Allow spec modules inside normal modules; these behave as if
10217 they were outermost. This violates the Blue Book, but is
10218 needed by the new grantfile mechanism. (A grant file is a
10219 spec module that gets included by the use_seize_file directive.)
10220 * ch-parse.y (struct module *current_module, push_module,
10221 pop_module): Support module nesting (for spec modules only).
10223 * ch-tree.h (struct module): New.
10224 * ch-grant.c (granted_decls): New list of declarations
10225 that have been granted into the outermode pseudo-module.
10226 * ch-grant.c (decode_mode): If the decl has a name,
10227 always write the name, not just if the decl has already
10228 been written. Since we write out all decls, we can assume
10229 it will be written later, and depend on the forward
10230 declaration kludges to catch it.
10231 * ch-grant.c (decode_decl): Don't write out _EXTERN.
10232 Instead write out standard (Blue Book) quasi-definitions.
10233 * ch-grant.c (push_granted): New function.
10234 * ch-grant.c (seize_implied_names): New function. Re-write
10235 how set element names are seized when a set type is seized.
10236 * ch-grant.c (chill_seize): Work by seraching the
10237 granted_decls list and copying the declaration.

10342 DECL if there, pass TREE_TYPE of decl to build_pointer_type.
10343 (variantfields, varianthack): Clean up.
10344 (variantfield): Check for IDENTIFIER_NODE, lookup its DECL if

10391 * ch-grant.ch (raw_decode_mode): New function, based on old
10393 * ch-grant.c (decode_mode); This is now just a wrapper around

10425 vents seg fault when only WITH operand is invalid.
10426 * ch-parse.y (label_spec): Correct assignment within IF expression which
10427 was intended to be equality test. Remove unused variables.
10428 * ch-tree.h: Add prototype. Remove unused EXCP_CODE enumeration, and
10429 prototyping editorial comments.
10430 * ch-typeck.c: Disable generation of code to validate array index for
10431 now. Should be done as a call-back from more generic array_ref code.

10580 build_chill_length: Move VARYING array handling before regular char
10582 * ch-expr.c chill_expand_expr: Disable concatenate code - we need to
10583 the VARYING status of the target to do this correctly. Use powersetlen
10584 for the powerset operations, not a byte length.
10585 * ch-loop.c: Make CREATE_SCOPE #define to enable creation of a new scope
10586 for each CHILL loop, as Z.200 requires. Add powerset and error flags
10587 to loop structure. Evaluate user's powerset expression into a temp,
10588 scan it destructively with __ffsetclrpowerset or __flsetclrpowerset
10589 for powerset loop. Only do loop-end assignments if NOT a powerset
10590 loop, which has much less overhead now.

10854 * ch-parse.y: Add working exception handling support.
10855 * ch-lex.l, ch-parse.y: Prefer standard type terminology
10856 (BOOLS, CHARS) even though non-standard (BITS, CHAR) is ok.
10857 * ch-grant.c: Fix various problems related to granting
10858 types such as bitsets.
10859 * ch-tree.c (build_bitstring_type): Set TYPE_MIN_VALUE

10866 New types chill_integer_type_node and chill_unsigned_type_node
10867 that correspond to the Chill source types INT and UINT.
10868 For now, these match the C 'short' types, but that should
10869 become a configuration option later,

10873 * ch-actions.c (build_chill_unary_op): allow NOT of a set.

10891 * ch-tree.def: add a new tree type - just for varying array

11124 chill front end to distinquish between true string types and
11125 arrays of char, since it uses ARRAY_TYPE for both, rather than
11126 trying to use the existing support for STRING_TYPE.
11128 Tue Jan 19 13:54:27 1993 Bill Cox (bill@rtl.cygnus.com)
11130 * ch-tree.h: added prototypes for all non-static CHILL functions.

11188 * chill.gperf, ch-hash.h: add Wilfried's tokens
11189 * ch-lex.l: fold in Wilfried's changes. Some tokens
11190 weren't getting recognized, and INSTANCE wasn't correctly
11191 reported to ch-parse.y as a PREDEF_MODEDCL.
11193 Thu Jan 14 15:02:39 1993 Per Bothner (bothner@cygnus.com)

11200 Wed Jan 13 15:19:15 1993 Per Bothner (bothner@cygnus.com)
11202 * calls.c, expr.c, function.c, stmt.c, varasm.c: Set
11203 MEM_IN_STRUCT_P for SET_TYPE where it is set for other aggregates
11204 * expmed.c (store_bit_field, extract_field_field): Undo
11205 yesterday's removal of MEM_IN_STRUCT_P "sanity test".
11207 * ch-decl.c (do_decls): Put back support for initializing.

11216 * ch-lex.l (convert_bitstring): Change to pack bits
11217 within words, not bytes, and to use machine bit-order
11218 (not always little-endian).
11219 * ch-parse.y: Allow BOOLS(n) as well as BITS(n).
11220 Use build_bitstring_type, not build_string_type.
11221 * expmed.c (store_bit_field, extract_field_field): Remove
11222 "sanity test" that prevents use with SET_TYPE.
11223 * tree.c (build_bitstring_type, build_powerset_type,
11224 build_string_type): Move (so far) Chill-specific functions to ...
11225 * ch-tree.c: ... new file.

11234 function __builtin_setbitinstring.
11235 * ch-expr.c (chill_expand_assignmment): Special-case handling

11257 * modules: use gdb rather than naked-gdb, to get opcodes
11258 in chill definition.
11260 Wed Jan 6 09:48:35 1993 Bill Cox (bill@cygnus.com)
11262 * ch-typeck.c: add code to handle references to elements of VARYING
11263 arrays. Simplify chill_give_type_to_expr. Add rough draft of run-
11264 time index checking for VARYING arrays (under #if 0).
11265 * ch-actions.c: new function cond_type_range_exception & calls.
11266 New function cond_range_exception, for more general range-checking.

11302 * ch-grant.c, ch-parse.y: Remove all code for explicitly
11303 calling initializer functions. This is not needed, since we
11304 use the same mechanism used for C++ static constructors.
11305 * ch-grant.c (chill_start_module_code): Make sure the
11306 init_name starts with the magic string also used for C++
11307 initializers. Also, don't embed the file name in the name,
11308 just use the module name.
11309 * ch-grant.c (chill_finish_module_code): Now that the
11310 initializer name follows the standard 'collect' convention,
11311 don't need to call assembler_constructor_alias, but can
11312 use the standard assemble_constructor instead.
11313 * varasm.c (assemble_constructor_alias): Remove no-longer-
11315 * ch-parse.y: Move code that is common to the beginning of
11316 all functions to a new macro INIT_ACTION.
11317 Make sure INIT_ACTION is also done for callaction, fixing a bug.
11318 * ch-parse.y (INIT_ACTION): Do chill_start_module_code()
11319 before emit_line_note(), not after.
11321 Mon Jan 4 11:43:12 1993 Bill Cox (bill@cygnus.com)
11323 * ch-parse.y: restore requirement for :upper-bound in array decl.
11324 * ch-actions.c: enhance upper, lower, length functions for VARYING.
11326 Mon Jan 4 09:28:44 1993 Bill Cox (bill@cygnus.com)

11343 * ch-parse.y: define IGNORED_DIRECTIVE
11344 * ch-typeck.c: subtract array's lower domain value, even if
11345 index expression is constant.

11349 * ch-lex.l (convert_float): Fix misspelling in error message.
11351 Sat Jan 2 16:02:16 1993 Per Bothner (bothner@rtl.cygnus.com)
11353 * Makefile.in: Took out chill-runtime support.
11354 Chill run times are now in ../chillrt, not ./chillrt.p
11356 Sat Jan 2 15:04:13 1993 Bill Cox (bill@cygnus.com)
11358 * ch-hash.h, chill.gperf: cleanup. fewer keywords seen by ch-parse.y.
11360 Sat Jan 2 13:27:49 1993 Per Bothner (bothner@rtl.cygnus.com)
11362 * ch-lex.l (check_newline): Use the orginal versions (derived
11363 from the C code, not the simplified, special-case version).
11364 Also, fix that version of check_newline to not call yylex()
11366 * ch-lex.l (yy_input): Call check_newline to handle
11367 newlines and check for # directives.
11368 * ch-lex.l (syntax): Don't recognize #-directives; these
11369 are now handled by check_newline.
11370 * ch-actions.c (lang_init): Call the modified version of
11371 check_newline(). Do this at the *after* we've initialized
11372 standard types, so this can be done while lineno is still 0.
11374 Sat Jan 2 10:57:20 1993 Bill Cox (bill@cygnus.com)
11376 * ch-hash.h, chill.gperf: add remaining reserved words.
11378 Sat Jan 2 09:59:55 1993 Bill Cox (bill@cygnus.com)
11380 * ch-tree.h, ch-parse.y, ch-lex.l: add remaining reserved words,
11381 names for exceptions
11383 Fri Jan 1 12:30:31 1993 Fred Fish (fnf@cygnus.com)
11385 * ch-tree.h (JOINER): Define joiner character the same way
11387 * ch-grant.c (chill_start_module_code): Use JOINER character
11388 to implement name mangling for the initializer function name.
11389 Algorithm is designed to be simple, distinct from C++ mangled
11390 symbols, and easy to convert to demangled form.
11392 Thu Dec 31 10:30:51 1992 Bill Cox (bill@rtl.cygnus.com)
11394 * ch-expr.c: make array assignments work with indirect refs.
11395 * ch-actions.c: prepare for array parameter handling.
11396 * ch-loop.c, ch-parse.y, ch-tree.def, ch-typeck.c: clean up.
11398 Thu Dec 31 15:29:20 1992 Per Bothner (bothner@rtl.cygnus.com)
11400 * ch-lex.l (yy_input): Re-write to return more than one
11401 character at a time (execpt when reading seize-files).
11402 Don't increment lineno until we start reading the next line.
11403 This fixes some off-by-one errors in lineno.
11405 Wed Dec 30 16:15:23 1992 Per Bothner (bothner@rtl.cygnus.com)
11407 * ch-convert.c: Assume use of new common.c.
11408 * ch-convert.c (convert_to_reference, convert_from_reference):
11409 New routines, to handle loc-identity declared variables and
11410 LOC parameters (both of which are implemented as references).
11411 * ch-lang.c (convert_to_boolean, convert_to_char): Move to
11412 ch-convert.c, where they would seem to belong.
11413 * ch-convert.c (convert): New function, since we no longer
11414 link in c-convert.c.
11415 * ch-expr.c (chill_expand_assignment): Handle by calling
11416 convert() instead of chill_comptypes().
11417 Also handle the LHS being a reference.
11418 * ch-parse.y: Add a procedure call as an action.
11419 * ch-parse.y (locdec, optlocinit): Move handling of
11420 loc-identity declarations from optlocinit to locdec
11421 - and add working semantics for it.
11422 * ch-parse.y (seizestatement, visibilty_stmt): Simplify.
11423 * ch-parse.y (grantstatement etc): Don't bother making list.
11424 * ch-lex.l: #include <sys/types.h> before <sys/stat.h>.

11428 * ch-parse.y, ch-expr.c: add support for declaring & assigning
11430 * ch-typeck.c: allow VARYING structures in assign_type_to_expr.
11432 Tue Dec 29 15:28:48 1992 Bill Cox (bill@cygnus.com)
11434 * ch-actions.c: implement expressions of arrays of char,
11435 ( concatenation, relationals ), correct type of code parameters
11436 * ch-expr.c: correct type of code parameters
11438 Tue Dec 29 11:16:19 1992 Bill Cox (bill@cygnus.com)
11440 * ch-decl.c: cleanup.
11441 * ch-parse.y: put emit_line_note() calls in lotsa places,
11442 per Fred's request; be sure that statements get counted also.
11443 * ch-lex.l: standardize function headers.
11445 Tue Dec 29 10:41:56 1992 Fred Fish (fnf@cygnus.com)
11447 * ch-decl.c (start_chill_function): Always return 1, rather
11448 than a random value.
11449 * ch-lex.l (check_newline): Add a version for chill that
11450 just snarfs the right value for main_input_filename out of
11451 the first line of the input file, without disturbing the
11452 lexer state or requiring it's assistance.
11453 * ch-actions.c (lang_init): Call check_newline, like the
11454 other language frontends, to get main_input_filename set
11455 from first line of input file.
11457 Mon Dec 28 18:49:01 1992 Bill Cox (bill@cygnus.com)
11459 * ch-parse.y: clean up conflicts. The remaining one is
11462 Mon Dec 28 17:28:40 1992 Bill Cox (bill@cygnus.com)
11464 * ch-parse.y, ch-lex.l, ch-actions.c: add stubs for I/O,
11465 clean up some parser conflicts.
11467 Mon Dec 28 15:00:20 1992 Bill Cox (bill@cygnus.com)
11469 * ch-parse.y, ch-lex.l: add keywords and parsing for most of
11472 Sat Dec 26 20:48:23 1992 Fred Fish (fnf@cygnus.com)
11474 * chillrt/chillrt0.c: Oops, SVR4 doesn't need leading '_'
11475 on build_exceptions.
11477 Sat Dec 26 11:00:36 1992 Fred Fish (fnf@cygnus.com)
11479 * ch-grant.c (chill_finish_module_code): Call
11480 assemble_constructor_alias rather than assemble_constructor.
11481 * varasm.c (assemble_constructor_alias): New function,
11482 like assemble_constructor, but also handles the case where
11483 ASM_OUTPUT_CONSTRUCTOR is not defined and GNU ld is not
11484 being used. Emits a symbol table alias name with the correct
11485 prefix for collect to find and add to the __CTOR_LIST__.
11486 * chillrt/chillrt0.c: Build on previous hack that gets
11487 _build_exceptions into the __CTOR_LIST__, to make it work
11488 for both the non GNU-ld case and for the SVR4 case.
11490 Tue Dec 22 18:24:55 1992 Bill Cox (bill@cygnus.com)
11492 * ch-loop.c: clean up location enumeration - one more

11499 Tue Dec 22 14:42:14 1992 Bill Cox (bill@cygnus.com)
11501 * ch-lex.l: readability cleanup
11503 Mon Dec 21 14:58:39 1992 Bill Cox (bill@cygnus.com)
11505 * ch-parse.y, c-decl.c: Add Jukka's Pascal WITH code.
11506 ch-loop.c: rough draft of location enumeration
11507 ch-lex.l, ch-expr.c, ch-decl.c: minor cleanup
11508 ch-actions.c: finish making pred() and succ() work.
11510 Mon Dec 21 10:04:35 1992 Bill Cox (bill@cygnus.com)
11512 * ch-actions.c: allow pred(char) and succ(char).
11514 Sun Dec 20 16:04:28 1992 Bill Cox (bill@cygnus.com)
11516 * ch-expr.c, ch-actions.c, ch-parse.y, ch-loop.c,
11517 c-expr.c: make DO WITH work.
11519 Sun Dec 20 12:22:53 1992 Bill Cox (bill@cygnus.com)
11521 * ch-loop.c, ch-actions.c, ch-typeck.c: powerset loops
11524 Sat Dec 19 14:20:23 1992 Per Bothner (bothner@cygnus.com)
11526 * c-typeck.c (process_init_constructor): Add warning if
11527 there is a duplicate default initializer element.
11528 * ch-typeck.c (chill_give_type_to_expr): New function,
11529 to handle coercion of an expression to context-given type,
11530 Takes care of untyped tuples, and case expressions.
11531 * ch-decl.c (do_decls), ch-typeck.c (chill_expand_return,
11532 chill_expand_result), ch-parse.y <assignaction>:
11533 Use chill_give_type_to_expr().
11534 * ch-typeck.c (chill_handle_case_label): New parameter list,
11535 to handle the (new) conventions for <case_label>, including
11536 default elements and ranges.
11537 * ch-parse.y <expanded_case_label>, ch-typeck.c
11538 (expand_case_expr): Use new version of chill_handle_case_label.
11539 * ch-decl.c (push_syndecls): Change parameters: Instead of
11540 TREE_LIST representing a compete <synonym definition statement>,
11541 just pass the parts of a single <synonym definition> as 3
11542 different parameters. Also, use chill_give_type_to_expr(),
11543 to handle untyped tuples in the RHS.
11544 * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct
11545 a tree - just call push_syndecls() on each <synonum_definition>
11547 * ch-parse.y (exprlist_get_single): Remove; no longer needed.
11548 * ch-parse.y: Handle <tuple> without mode name diferently from
11549 <tuple> with mode name. The latter is a <primval> that can be
11550 in most contexts, but if the <mode name> is missing, the <tuple>
11551 is only allowed in certain contexts. Use the new non-terminal
11552 <untyped_expr> to indicate those contexts where untyped tuples
11553 (and case expressions) are valid because the expression gets a
11554 type from its context (such as the RHS of an assignment).
11555 Use chill_give_type_to_expr in those contexts.
11557 Sat Dec 19 14:01:26 1992 Bill Cox (bill@cygnus.com)
11559 * ch-actions.c, ch-loop.c, Makefile.in: looping stuff.
11561 Sat Dec 19 10:16:20 1992 Bill Cox (bill@cygnus.com)
11563 * ch-parse.y: clean up warning messages from byacc. bison
11564 still complains thrice.

11592 seems to have allowed getting rid of all of the expr_or_list hair.
11593 * ch-decl.c (do_decls): Undo Tiemann's change to "Handle
11594 initialization of multiple variables by a tuple" - the
11597 Wed Dec 16 11:17:53 1992 Bill Cox (bill@cygnus.com)
11599 * ch-parse.y: complete re-write of DO statement handling.

11673 * c-typeck.c (process_init_constructor): Warn about duplicate
11674 labels for labelled initializer elements.
11675 * ch-lex.l (various operator tokens, such as "+"): Don't
11676 set yylval.code to a TREE_CODE; this is better done in parser.
11677 * ch-parse.y: Some work with case labels and tuples.
11678 Get literal range as tuple (and case) labels working.
11679 Fix some problems introduced by recent grammar overhaul.

11683 * ch-actions.c, ch-parse.y ch-tree.h ch-expr.c, ch-typeck.c:
11684 got long, real expressions working. We can also call a func-
11685 tion and use its return value.
11687 Thu Dec 10 14:45:17 1992 Per Bothner (bothner@cygnus.com)
11689 * ch-parse.y: Major change to remove or at least identify
11690 parser ambiguities. One result: We now allow actions that
11691 start with '(', as required by teh Blue Book. This does break
11692 some things; look for FIXME for things that need work.
11693 * ch-typeck.c (chill_expand_case_expr): We need an extra
11694 level of looping to (in the future) support <case label
11695 specification>s with more than one <case label list>.

11724 indicate we are done with initialization.
11726 * ch-decl.c (do_decls): Set TREE_PUBLIC if we are doing a
11728 (start_chill_function): Ditto.
11730 * ch-lex.c (convert_bitstring): Set TREE_CONSTANT.

11732 equality comparison operators.
11734 * ch-parse.y: Clear CURRENT_LOCNAMELIST after calling do_decls.

11747 * tree.def: Move CARD_EXPR and SET_LE_EXPR back down with the other
11748 Pascal-required ones, since C++ no longer needs them. When
11749 Chill's public, a comment can be added to the effect that
11750 SET_LE_EXPR is also used by Chill.
11752 Fri Dec 4 12:05:01 1992 Bill Cox (bill@cygnus.com)
11754 * Restore CARD_EXPR and SET_LE_EXPR to tree.def.

11793 (push_newmode,push_synmode): Call `fixup_unknown_type' when we
11794 see a declaration that uses `unknown_type_node'. FIXME.
11796 * ch-grant.c (decode_constant): New function.
11797 (decode_decl): Call `decode_constant' for CONST_DECLs.
11799 * ch-lex.l (char action): Use ridpointers instead of
11800 lookup_name to get "char"'s declaration.
11802 * ch-parse.y: Call `build_lang_decl' instead of `build_decl'
11803 when we need to build a TYPE_DECL.
11805 Tue Dec 2 09:44:05 1992 Bill Cox (bill@cygnus.com)
11807 * ch-typeck.c: clean up a gcc warning with a forward
11808 declaration of build_string_type.
11810 Tue Dec 1 16:51:05 1992 Bill Cox (bill@cygnus.com)
11812 * ch-actions.c: completely remove those builtin calls
11813 that are duplicated in c-decl.c
11815 Tue Dec 1 16:38:51 1992 Fred Fish (fnf@cygnus.com)
11817 * ch-actions.c (lang_init): Ifdef out initializations for
11818 __builtin_abs and __builtin_fabs, since they are duplicates of
11819 initializations in c-decl.c, and trigger spurious warnings.
11821 Tue Dec 1 16:35:18 1992 Bill Cox (bill@cygnus.com)
11823 * ch-parse.y: make size() work with a typename argument.

11852 * chillsh: New script frontend (ala g++), installed as "chill".
11853 Can't be called "chill.sh" because make tries to cat it into the
11854 "chill" directory. Can't be called just "chill" cause that's
11855 already there as a directory.
11856 * Makefile.in: Add rules to install chillsh as "chill".
11857 * chill/libchill.c: Temporarily ifdef out stuff that wants
11858 to conflict with i486/SVR4 runtime or wants to pull in librmt.a,
11859 which itself causes linkage to fail.
11861 Mon Nov 30 16:28:19 1992 Bill Cox (bill@cygnus.com)
11863 * ch-lex.l: added keywords for TRUNC, ROUND, FLOAT, LFLOAT
11864 conversion routines.
11865 * ch-parse.y: added %tokens for TRUNC, ROUND, FLOAT, LFLOAT.
11866 Added production for SIZE(expr).

11887 pred, succ, etc. Put flex -a option into Makefile.in, so we can
11888 clean up the lexer soon.

11908 the context of RETURN and RESULT actions.
11909 * chill.y (assignaction): Handle case expressions in the
11910 context of the RHS of an assignment action.
11911 * chill.y (caseaction): Remove spurious duplicate OF in grammar.
11912 * chill.y: Handle labeled structure tuples.
11913 * chill.y: New rules to parse CASE expressions.

11922 using the mode of the LHS and the expected type of the TUPLE.
11923 * chill.y: Implement initialization.
11924 * chill.y: Fix some syntax bugs (forbidlist must be surrounded
11925 by parentheses), and remove or note ambiguities.
11926 * chill.y: Started converting layout style to be like c-parse.in.
11927 * chill.y: Implement IF expressions.
11928 * chill.y: Added syntax rules for tuples. Labelled and unlabelled
11929 array tuples should now work (in some contexts).
11930 * ch-actions.c: Initialize doing_chill_thang to 1.
11931 * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
11932 initializer, to make pushdecl and finish_decl work.
11933 * c-decl.c (convert_for_assignment): If Chill, don't convert
11934 function and arrays into pointers. (Maybe functions should
11935 still be converted?)
11936 * c-typeck.c (grokdeclarator): Allow functions in Chill
11937 to return arrays and functions.
11939 Mon Nov 16 15:40:47 1992 Per Bothner (bothner@rtl.cygnus.com)
