3230 of the result to class of first value in expression.

3234 subsequent calls. Emit code immediately instead of building a
3235 compound expr.

3302 bit-string, bit_one_node and bit_zero_node were switched.

3388 * loop.c (toop_loop_end_check): Replace build1 (ADDR_EXPR ...)
3389 with call to force_addr_of (which calls mark_addressable).
3390 * expr.c (build_chill_descr, build_chill_inttime): Likewise.
3391 * inout.c (build_chill_writetext): Likewise.
3393 Mon Sep 26 05:19:21 1994 Wilfried Moser (moser@rtl.cygnus.com)

3427 * expr.c (build_concat_expr): Fix calculation of result_size.
3429 Wed Sep 21 00:54:21 1994 Per Bothner (bothner@kalessin.cygnus.com)
3431 Give up on trying to use the cleanup mechanism in stmt.c to
3432 make sure the exception handler get unlinked on goto/exit/return.
3433 Instead, do it ourselves. (Much simpler.)
3434 * except.c, ch-tree.h (action_nesting_level): New global.

3476 unlink from exception stack if we return/exit/goto from here.
3477 * loop.c (begin_loop_scope): Move pushlevel from here ...
3478 * parse.c (parse_do_action): ... to here.

3481 * parse.c (parse_loc_declaration): If global_bindings_p (),
3482 treat as static.

3496 * lex.l (readstring): Add processing of control sequence
3497 in character string literals. The granting mechanism writes
3498 this to grant files.
3500 Tue Sep 13 06:19:42 1994 Wilfried Moser (moser@rtl.cygnus.com)
3502 * expr.c (compare_records): In case of -fpack do always
3503 a memcmp instead of comparing each field of the

3516 (add_taskstuff_to_list): Add a new argument, which is
3517 the entrypoint of a process.
3518 (build_process_header): Change PROCESS arguments to be
3519 like arguments of a function. There will be a wrapper
3520 which is the real entry point for a PROCESS. This wrapper
3521 is automatically build after a PROCESS definition and gets
3522 as argument a pointer to a structure looking like the
3523 arguments of the PROCESS. This wrapper will call the
3524 PROCESS (see build_process_wrapper).
3525 (build_process_wrapper): New function (see above).
3526 (build_start_process): Change processing of arguments.
3527 (tasking_setup): Add processing of a different entry point
3528 in case of PROCESSes.

3534 pushlevel().
3536 * grant.c (print_proc_tail): Remove special processing
3537 of PROCESSes, they look now like normal functions.
3539 * decl.c (init_decl_processing): Add declaration of memcmp
3540 function.
3542 * ch-tree.h: Add new prototype for build_process_wrapper,
3543 change prototypes for add_taskstuff_to_list and

3555 generated.
3556 * Makefile.in (GNUCHILL_VERSION): Remove it, its defined in
3557 Make-lang.in.
3559 * chill.in: In case of -fgrant-only pass "-S -o /dev/null"
3560 to the compiler to avoid generation of an object file.
3562 Thu Sep 8 12:07:28 1994 Per Bothner (bothner@kalessin.cygnus.com)
3564 * convert.c (display_int_cst), ch-tree.h: New function.
3565 * convert.c (digest_array_tuple): Use digest_int_cst to
3566 provide better error messages. Return error_mark_node on error.
3567 * grant.c (decode_const): Simplify by using digest_int_cst.
3568 * grant.c (format_character, find_assoc): Removed.
3570 * decl.c (do_decl): Add missing TREE_CHAIN.
3572 * decl.c (finish_incomplete_decl): Removed.
3573 (init_decl_processing): Don't set incomplete_decl_finalize_hook.
3574 (finish_decl): Remove old C-specific code to deduce size of
3575 array from initialization.
3576 (complete_array_type): Just make it abort.
3578 * except.c (finish_handler_array): Avoid calling C-specific kludge
3579 complete_array_type.
3581 * convert.c (digest_constructor): Rename, and re-write to:
3582 (digest_array_tuple, convert): No longer use the code in
3583 ../c-typeck.c; use a Chill-only implementation (sigh).
3585 * typeck.c (chill_expand_tuple): Remove unneeded call to
3586 complete_array_type.
3588 * expr.c (fold_set_expr), grant.c (decode_constant),
3589 typeck.c (expand_constant_to_buffer): Update name of called
3590 function unpack_set_constructor to get_set_constructor_bits.
3591 * expr.c (powersetlen ): Remove redundant call to convert.
3593 * ch-tree.h (unpack_set_constructor): Removed obsolete declaration.
3595 * inout.c (build_chill_writetext): Handle 64-bit integer literals
3596 by trying to convert them to a smaller type.
3598 * lex.l (convert_number): Always use long long type (possibly
3599 unsigned) to avoid problems with constant folding truncation.
3601 Mon Sep 5 08:08:22 1994 Wilfried Moser (moser@rtl.cygnus.com)
3603 * ch-tree.h (enum chill_built_in_function): Add BUILT_IN_QUEUE_LENGTH.
3604 Add new prototype (see tasking.c).
3606 * expr.c (build_generalized_call): Add processing of

3609 * tasking.c (build_queue_length): New function.
3611 * tasking.c (tasking_init): Add new external function definition.
3613 Thu Sep 1 15:38:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3615 * lex.l (default_lex): New function. Progress towards
3616 getting rid of [f]lex.
3618 * lex.l (convert_number): Use mul_double and add_double.
3619 Set result type to a reasonable type in which the literal
3620 will fit. Give error message if literal is too big.
3622 * lex.l (equal_number): Switch (temporarily) to permanent obstack.
3624 * typeck.c (build_chill_slice_with_range): Check for empty
3625 slice *after* we have checked for upper/lower limit in range.

3628 CHAR ranges are represented as INTEGER_TYPEs.)
3630 * tasking.c (build_process_header): Add missing call to
3631 expand_start_bindings.
3632 * parse.c (end_function): Add missing expand_end_bindings.
3634 Wed Aug 31 17:25:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3636 * decl.c (init_decl_processing): Set set_alignment.
3638 Tue Aug 30 16:40:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
3640 * actions.c (print_missing_cases, check_missing_cases,
3641 BITARRAY_TEST, BITARRAY_SET): New functions and macros,
3642 to check for completeness of case actions and expressions.
3643 * decl.c (c_decode_option, init_decl_processing):
3644 Don't set warn_switch.
3645 * expr.c (chill_expand_case_expr): Call check_missing_cases
3646 instead of check_for_full_enumeration_handling.
3647 * parse.c (parse_case_actions): Call check_missing_cases.
3649 * expr.c (build_chill_binary_op): Remove some dead code.
3650 * expr.c (chill_truthvalue_conversion): Call build_chill_binary_op
3651 instead of build_binary_op.
3652 * ch-tree.h (binary_op_error, build_binary_op): Unused. Removed.
3654 * parse.c (end_function): Use kept_level_p in parameter to
3655 poplevel. This reverts a June 13 change.
3657 Fri Aug 26 11:50:19 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3659 * configure: Ignore --without, as ../configure does.
3661 Wed Aug 24 01:17:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3663 * lex.l: Change rule for decimal numbers to allow identifiers
3664 to start with an underscore (_).
3666 Fri Aug 19 16:38:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
3668 * tasking.c (build_receive_signal_case_label): Remove backwards
3669 chill_convert_for_assignment (which converted whatever garbage
3670 was in the *target* to the type of the signal argument!).
3672 Fri Aug 19 07:10:43 1994 Wilfried Moser (moser@rtl.cygnus.com)
3674 * inout.c (build_chill_io_list_type, build_enum_tables),
3675 tasking.c (build_tasking_struct): Temporarily reset
3676 maximum_field_alignment to 0, so that the compiler-built
3677 data structures needed by the RTS can be independent of -fpack.
3679 Thu Aug 18 13:39:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3681 * typeck.c (build_init_struct): Temporarily reset
3682 maximum_field_alignment to 0, so that the compiler-built
3683 data structures needed by the RTS can be independent of -fpack.
3685 Wed Aug 17 23:48:33 1994 Wilfried Moser (moser@rtl.cygnus.com)
3687 * parse.c (parse_primval, expect, parse_on_exception_list):
3688 Print error message only in pass 2.
3690 Wed Aug 17 13:47:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3692 * decl.c (switch_to_pass_2): Revert June 13 change,
3693 (Don't exit after pass 1 if an error was found.)
3695 * ch-tree.def (SLICE_EXPR): New tree-code.
3696 * typeck.c (build_chill_slice): For building a slice of a
3697 bit-string, just generate a SLICE_EXPR.
3698 * decl.c (init_decl_processing): Declare __pscpy.
3699 * actions.c (chill_expand_assignment): Handle a SLICE_EXPR
3700 on the LHS of assignment, by calling __pscpy.
3701 * expr.c (chill_expand_expr): Handle SLICE_EXPR (as a RHS
3702 value) by using __psslice to copy slice to a temp.
3704 Wed Aug 17 05:52:44 1994 Wilfried Moser (moser@rtl.cygnus.com)
3706 * Make-lang.in: Change version of GNUCHILL compiler to 1.4.1.
3707 * expr.c (build_chill_length): Enable LENGTH built-in to process
3708 Buffers and Events too (Z.200/1992).
3709 * lex.l (yywrap): Always set yyin to finput and/or grt_in. On
3710 a linux system the previous version was not able to run.
3711 * tasking.c: Correct processing of infinite buffer- and event-length
3712 to avoid RANGEFAIL warning.
3714 Thu Aug 11 11:46:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3716 * parse.c (parse_if_expression_body): Don't call the C-specific
3717 build_conditional_expr. Just do build_nt (COND_EXPR, ...).
3718 * convert.c (convert): Convert a COND_EXPR by converting
3719 each branch.
3721 * convert.c (convert): Don't call convert before
3722 convert_to_reference. It's apt to do weird and unneedful things.
3723 * convert.c (convert): If the expression is varying, just call
3724 varying_to_slice, which simplifies quite a bit.
3726 * ch-tree.h (varying_to_slice): Add prototype.
3727 * typeck.c (varying_to_slice): Remove prototype.
3729 * satisfy.c (satisfy): Move case PAREN_EXPR from type 'e'
3730 to type '1'.
3732 * except.c (emit_setup_handler): Temporarily reset the
3733 maximum_field_alignment to zero so the compiler's exception
3734 data structures can be compatible with the run-time system,
3735 even when we're compiling with -fpack.
3737 * expr.c (compare_records): Call saved_if_needed on operands.
3739 * expr.c (build_set_expr case NE_EXPR): Don't use __nepowerset
3740 which has been reimplemented to just call __eqpowerset and
3741 invert the result. Inline this new implementation by
3742 handling as EQ_EXPR, and inverting the result.
3743 * decl.c (init_decl_processing): Don't define unused __eqpowerset.
3745 * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
3746 type boolean_type_node, not void_type_node. (Fixing this
3747 avoids a crash in the back-end.)
3749 * grant.c (decode_constant): In a CALL_EXPR, if the argument
3750 list is not a TREE_LIST (as in string repetiation), don't
3751 emit parentheses.
3753 Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3755 * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
3756 CONST_DECL is from a SET definition. (This is safer than
3757 checking that the type is ENUMERAL_TYPE, because synonym
3758 definitions may have a NULL TREE_TYPE.)
3759 Also, if we have duplicate enums whose types are identical,
3760 this is an error.
3761 * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
3762 an extra 'quiet' parameter, which is true if we're called from
3763 bind_sub_modules. (In that case an error message about duplicated
3764 decls would be repeated later, so suppress it.)
3766 * parse.c (stmt_count): Removed, not used.
3767 (INIT_ACTION): Call emit_line_note only if !ignoring.
3768 (parse_begin_end_block): Do INIT_ACTION even if ignoring.
3770 Fri Aug 5 12:39:11 1994 Per Bothner (bothner@kalessin.cygnus.com)
3772 * parse.c (parse_untyped_expr): Add missing semi-colon.
3774 Thu Aug 4 17:40:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
3776 * parse.c (parse_untyped_expr): Fix various problem for the
3777 case that we see a '(': Add missing 'case' keyword.
3778 Only recurse if '(' is followed by 'if', 'case' or '[',
3779 and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
3781 * parse.c (parse_send_action): Remove extra nreverse.
3783 Thu Jul 28 04:00:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3785 * expr.c (build_allocate_global_memory_call, build_allocate_memory_call):
3786 Add new checks.
3788 Tue Jul 26 22:48:15 1994 Michael Tiemann (tiemann@blues.cygnus.com)
3790 * parse.c (parse_untyped_expr): Added missing "case" before LPRN.
3791 Added a missing call to `require' as well.
3793 Tue Jul 19 10:30:12 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3795 * lex.l (yywrap): Define as yywrap_chill to avoid conflicts with
3796 the extern declaration in the flex skeleton.
3798 Mon Jul 18 23:06:04 1994 Per Bothner (bothner@kalessin.cygnus.com)
3800 * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
3801 Check the type of the instance expr using CH_COMPATIBLE,
3802 and not just == instance_type_node. (This allows
3803 the expression to have mode READ INSTANCE).
3804 * tasking.c (build_instance_type): Give instance_type_node
3805 a non-null novelty (i.e. different from a struct).
3806 * tasking.c (build_receive_case_start, build_delay_case_start):
3807 Check that for a location using CH_LOCATION_P.
3809 Mon Jul 18 13:22:23 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
3811 * expr.c (finish_chill_unary_op): Use TREE_SET_CODE not TREE_CODE
3812 to modify a tree code.
3814 Mon Jul 18 11:24:57 1994 Bill Cox (bill@rtl.cygnus.com)
3816 * convert.c (digest_structure_tuple): Fix thinko in TREE_CODE
3817 comparison.
3819 Mon Jul 18 05:40:15 1994 Doug Evans (dje@canuck.cygnus.com)
3821 * decl.c (warn_bad_function_cast): Define so cc1chill will link.
3823 Thu Jul 14 18:37:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3825 * parse.c (parse_send_action): Do tree_cons *before* checking
3826 for end of loop.
3828 Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3830 * convert.c (digest_structure_tuple): Don't use convert to
3831 coerce initial value, use chill_convert_for_assignment instead.
3832 (Thus we also get range_checking.)
3834 * expr.c (build_chill_card): Use force_addr_of instead of
3835 build_chill_addr_expr.
3837 * loop.c (build_temporary_variable): Stylistic tweak.
3838 * loop.c (maybe_make_for_temp): Initialize temp using
3839 explicitly, not using assignment. Avoids a problem if
3840 the expression is read-only.
3841 * typeck.c (smash_dummy_type): Always used the saved TYPE_NAME
3842 and CH_NOVELTY_FLAG.
3844 Wed Jul 6 20:12:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3846 * expr.c, ch-tree.h (finish_chill_unary_op): New function,
3847 based on code ripped out of build_chill_unary_op.
3848 (build_chill_unary_op): Call finish_chill_unary_op unless pass==1.
3849 * satisfy.c (satisfy): Call finish_chill_unary_op when needed.
3851 Mon Jun 27 11:29:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3853 * tree.c (save_if_needed), ch-tree.h: New function.
3854 * typeck.c (build_chill_slice_with_range,
3855 build_chill_slice_with_length): Call save_if_neeed on array arg.
3856 * expr.c (varying_to_slice): Re-write to use save_if_needed.
3858 * typeck.c (extract_constant_from_buffer): Handle BOOLEAN_TYPE.
3860 Mon Jun 27 01:11:10 1994 Wilfried Moser (moser@rtl.cygnus.com)
3862 * inout.c (build_chill_io_list_type): Change layout of __tmp_WIO_list
3863 that it is always the same, regardless if compiled with -fpack
3864 or not.
3866 Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3868 * lex.l (yywrap): Kludge to work around mis-synchronization
3869 between lexer (which read ahead) and parser: Don't emit
3870 (left-over) uze_seizefile directives at the end of file.
3872 * typeck.c (build_chill_array_ref): Allow the derived
3873 array indexing syntax for arrays of bit strings.
3874 Add a comment explaining why.
3876 * typeck.c, ch-tree.h (string_assignment_condition): Change
3877 the interface. Return a boolean expression (which can be
3878 used in a conditional at run-time); never expand anything.
3880 * actions.c (chill_convert_for_assignment): Check
3881 string_assignment_condition here, rather than in callers.
3882 * actions.c (chill_expand_assignment): Don't need to check
3883 string_assignment_condition here.
3884 * expr.c (build_chill_function_call): Likewise.
3885 * satisfy.c (safe_satisfy_decl): Update accordingly.
3886 * decl.c (do_decl): Simplify testing and conversion by
3887 deferring everything to chill_convert_for_assignment.
3889 * parse.c: Combine the two variables 'ignore_exprs' and
3890 'ignore_actions' into one variable called 'ignoring'.
3891 * ch-tree.h: Add 'extern int ignoring'.
3892 * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
3893 Rename ignore_actions and ignore_exprs to ignoring.
3894 Remove unneeded extern declarations.
3895 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3896 build_chill_arrow_expr, build_generalized_call, build_delay_action,
3897 build_buffer_type, build_event_type): I changed my mind. It is
3898 cleaner to check for 'ignoring' in the parser, rather than here.
3899 * parse.c (parse_action, parse_primval, parse_opt_mode):
3900 Therefore we must check for ignoring here.
3901 * parse.c (parse_loc_declaration): Set ignoring in pass 2
3902 when parsing the mode.
3904 * tasking.c (generate_tasking_code_variable): Do arithmetic
3905 on signal_code etc using unsigned rather than signed shorts.
3907 * grant.c (static char* current_grant_modename): Removed.
3908 * grant.c (decode_decl case CONST_DECL): Remove error message.
3910 * Make-lang.in (CHILL_SRCS): Add $(srcdir)/ch/parse.c.
3911 * Makefile.in: Fix dependencies for parse.o.
3912 Remove some duplicate dependencies for $(TREE_H).
3914 Mon Jun 13 14:25:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3916 * typeck.c (build_chill_cast): Allow a value cast between
3917 non-discrete object of the same size, but with a pedwarn.
3918 * typeck.c (bit_string_assignment_condition,
3919 char_string_assignment_condition): Merge near-duplicate functions
3920 and place the code in string_assignment_condition.
3922 * decl.c (parm_flag, declare_parm_level, in_param_level_p):
3923 Removed. Not used.
3924 * decl.c (start_chill_function, finish_chill_function): Make
3925 parameter level have same nesting level as body, as required by Z200.
3926 * decl.c (switch_to_pass_2): Always exit if an error has been found.
3927 * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
3928 generated from GRANT ALL.
3929 * decl.c (lookup_name_for_seizing): Don't seize from
3930 the nesting level of builtins (predefined objects).
3931 * decl.c (lookup_name_for_seizing): Make more robust on error.
3933 * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
3934 be 'RESULT' (or 'result'). This makes it more accessible from gdb.
3935 Also, use do_decl to declare it, so that debugging symbols are
3936 generated. And, re-arrange so that actions that need to
3937 be done both passes (such as push_levels) use the same code.
3939 * parse.c (get_type_of): If ignore_exprs, don't lookup name.
3940 * parse.c (end_function): Fix poplevel params.
3941 * parse.c (expect): Don't read forwards on an error.
3942 * parse.c (parse_field): Don't define two tag_list locals!
3943 * parse.c (parse_pass_1_2): Better error message.
3945 * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
3946 parse_opt_mode, rather than vice versa. If parse_opt_mode
3947 returns NULL_EXPR, then parse_mode gives an error.
3948 Change parse_opt_mode (and any functions it calls) to only
3949 return NULL_TREE if there is no mode (even on ignore_exprs).
3950 (parse_set_mode, parse_structure_mode, parse_procedure_mode):
3951 Never return NULL_EXPR.
3952 * tasking.c (build_buffer_type, build_event_type): Return
3953 void_type_node instead of NULL_EXPR if ignore_exprs is true.
3955 * parse.c (parse_synonym_definition): Call parse_untyped_expr
3956 only if we have a mode.
3957 * parse.c (parse_send_action): Parse list of untyped_expr's,
3958 rather than a list of (typed) expressions.
3959 * parse.c (parse_primval): Emit error if '[' seen without
3960 preceding mode name. (If this is to be allowed, call
3961 parse_untyped_expr instead.)
3963 * parse.c (parse_array_index): Renamed to ...
3964 (parse_index_mode): ... to match Z200 terminology.
3965 Re-write to resolve some of the nastier ambiguities,
3966 and allow things like ' CHAR(10) : CHAR(20) '.
3968 * parse.c (parse_tuple_element): Change interface to return
3969 reversed list, so don't call nreverse.
3970 * parse.c (parse_tuple): No longer nreverse element list here.
3971 * parse.c (parse_opt_element_list): Do nreverse here instead.
3972 * parse.c (parse_case_label_list): Call nreverse at end.
3974 Fri Jun 10 15:36:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
3976 * typeck.c (chill_similar): Remove bogus "else".
3978 Wed Jun 8 00:01:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
3980 * ch-tree.h (TYPE_ARRAY_MAX_SIZE): New macro (and comment)
3981 to make it clearer that we are using TYPE_MAX_VALUE in a special way.
3982 * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
3983 * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
3984 * convert.c (convert): When converting a fixed string/array
3985 to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
3986 of (the type of) the padding.
3987 * convert.c (convert): If the concatenation is non-constant, use
3988 the low-level 'build' to set the type of the result (which is usually
3989 a fixed-size array) rather than depend on build_chill_binary_op
3990 to figure it out (it's unable to simplify the size to a constant).
3992 Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
3994 * lang.c (lang_decode_option): Let -fspecial_UC imply
3995 -fno-ignore-case without requiring it explicitly.
3996 * lang.c (lang_decode_option): Support (experimentally)
3997 the -fpack and -fno-pack flags.
3999 Thu Jun 2 20:49:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4001 * configure: Add support for --program-prefix and --program-suffix.
4003 Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
4005 * convert.c (digest_constructor): Check that initial value
4006 is compatible with element mode before calling convert.
4007 * typeck.c (chill_compatible): A string mode is not compatible
4008 with an untyped constructor.
4009 * decl.c (do_decl): Clean up error messages. Use error_with_decl.
4011 * ch-tree.h: Fix inconsistencies: bool_true_node ->
4012 boolean_true_node, and bool_false_node -> boolean_false_node.
4013 * typeck.c (valid_array_index_): Minor simplification.
4015 Tue May 31 04:33:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
4017 * inout.c (build_chill_writetext): Add correct processing
4018 of POWERSET RANGE (setmode).
4020 * lex.l (same_file): Add searching for file(s) in
4021 seize_path_list.
4023 Fri May 27 14:22:42 1994 Per Bothner (bothner@kalessin.cygnus.com)
4025 * Make-lang.c (CHILL.mostlyclean, CHILL.distdir): Don't list
4026 yacc/bison output files, since the grammer is no longer in yacc.
4027 * config-lang.in (diff_excludes): Likewise.
4029 Thu May 26 16:38:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
4031 * gperf, hash.h, lex.l, parse.h: Rename PROCESS_TYPE token
4032 (in some files spelled PROCESS_TYPE_ to avoid clashes
4033 with the PROCESS_TYPE tree_code) to PROCESS_TYPE_TOKEN.
4035 Thu May 26 02:18:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
4037 * timing.c (build_cycle_start): Change call to __define_timeout.
4038 * decl.c (init_decl_processing): Change definitions of
4039 __define_timeout and __wait_timeout.
4041 Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
4043 Replace yacc-based parser with a recursive-decent parser.
4044 (This may seem backwards, but Chill [like C++] is not a
4045 language that is remotely LALR(1). Using a R-D parser
4046 allows us to use look-ahead and to back-up to resolve the
4047 difficult ambiguities.)
4048 * parse.y: Removed.
4049 * parse.c, parse.h: New files, containing new r-d parser.
4050 * Makefile.in: Update accordingly.
4051 * actions.c (chill_convert_for_assignment): Don't return
4052 NULL_EXPR if ignore_exprs is true. It simplifies the parser
4053 if we consistently reserve NULL_EXPR for a missing expression.
4054 * expr.c (build_chill_function_call): Likewise.
4056 * lex.l: Tweaks for new parser.
4057 * lex.l (prepare_paren_colon, paren_paren_colon_level,
4058 paren_level): Ugly hack no longer needed.
4060 * expr.c (build_chill_function_call): Cleanup.
4061 Call chill_convert_for_assignment to convert IN/INOUT
4062 paramaters on both input and output. For LOC parameters,
4063 give error if actual is a non-referable location.
4064 * actions.c (convert_for_assignment): Add new parameter (a
4065 "place" string used in error messages).
4066 * actions.c (adjust_parm_or_field): Removed.
4067 * actions.c (chill_expand_assignment): Take just a single LHS,
4068 and move support for multiple assignments to ...
4069 (expand_assignment_action): ... here. Some cleaning up.
4070 * timing.c (build_cycle_start): Adjust accordingly.
4071 * actions.c (expand_assignment_to_varying_array): Likewise.
4072 * tasking.c (many places): Ditto.
4073 * ch-tree.h: Fix declarations appropriately.
4075 * parse.c (parse_defining_occurrence_list): Return a single
4076 IDENTIFIER_NODE (instead of a singleton list) in the common
4077 case. Minor complication to save a minor amount of space.
4078 * decl.c (do_based_decls): Move guts of code into ...
4079 (do_based_decl): ... this new function.
4080 * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
4081 * decl.c (push_syndecl): Replace by ...
4082 (push_syndecl): ... (which only supports a single name).
4083 (push_modedef): Only handle a single name.
4084 * tasking.c (build_process_header, build_signal_struct_type):
4085 Adjust accordingly.
4087 * expr.c (build_generalized_call): Handle string repetition.
4088 * expr.c (build_chill_repetition_op): Change interface.
4089 * grant.c (decode_constant): Allow parameter list to be
4090 a non-TREE_LIST. (Used for string repetition.)
4092 Wed May 25 11:28:48 1994 Per Bothner (bothner@kalessin.cygnus.com)
4094 * lex.l (make_identifier): Replaced by ...
4095 (read_identifier, handle_name): ... new functions.
4096 * lex.l: Parse an identifiers using read_identifier using
4097 read_identifier and handle_name, rather than having [f]lex
4098 do it. (One reason is that lex uses a fixed-size buffer.)
4100 * lex.l (read_directive, skip_directive): New functions.
4101 Use them to parse compiler-directives, instead of rather
4102 ugly and useless use of lexer start conditions.
4104 Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4106 * decl.c (unnamed_module_number): Renamed to ...
4107 (module_number): .. and make non-static.
4108 (push_module): Always increment module_number.
4109 * lex.l (yywrap): Print warning if no modules seen.
4111 * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
4112 decl to current_seizefile_name (which is unreliable).
4113 * grant.c (chill_grant): Set it here instead.
4115 * expr.c (fold_set_expr): Use int_size_in_bytes instead of
4116 TYPE_PRECISION (which is not defined for a SET_TYPE).
4118 Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
4120 Cleanup to remove need for variables in common storage.
4121 * decl.c: Remove unused use of current_obstack.
4122 * actions.c (maybe_chill_check_decl): Remove unused function.
4123 * actions.h, lang.c: Remove uses of doing_chill_thang.
4124 * ch-tree.h (void_list_node): Make extern (rather than common).
4125 * decl.c (void_list_node): Add definition.
4127 Thu May 19 06:54:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
4129 * configure (build): Build canon_host and canon_target
4130 to pass it to all subsequently generated Makefiles (needed
4131 for testsuite/execute in case of cross build).
4133 Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4135 * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
4136 the input type, which loses with the no-longer-new 2-pass
4137 implementation, since the input "type" could be an IDENTIFIER_NODE.
4138 * grant.c (raw_decode_mode): Rename to decode_mode.
4140 Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
4142 * typeck.c (chill_location): Neither a STRING_CST nor a
4143 CONSTRUCTOR is a location.
4144 * typeck.c (chill_root_mode): Convert a function to a
4145 pointer-to-function.
4146 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
4147 build_chill_arrow_expr): If ignore_exprs, return operand
4148 rather than NULL_EXPR. This makes it easier for the parser to
4149 distinguish missing expressions.
4150 * expr.c (build_max_min): Convert the lower bound of a
4151 set to a long before calling run-time routine.
4152 * expr.c (build_chill_pred_or_succ): Use discrete_type_p
4153 to check the argument type.
4154 * expr.c (build_chill_arrow_expr): If argument is not a location,
4155 do a predwarn if it is a STRING_CST or has function type.
4157 Tue May 17 06:05:13 1994 Wilfried Moser (moser@rtl.cygnus.com)
4159 * configure (build): Remove building of canon_host and canon_target.
4160 It doesn't work in any case.
4162 Mon May 16 02:10:35 1994 Wilfried Moser (moser@rtl.cygnus.com)
4164 * configure (build): Build canon_host and canon_target
4165 to pass it to all subsequently generated Makefiles (needed
4166 for testsuite/execute in case of cross build).
4167 * Make-lang.in (chill-runtime): Change chill to CHILL in the case
4168 statement to build chill-runtime automatically.
4170 Mon May 9 15:30:08 1994 Doug Evans (dje@canuck.cygnus.com)
4172 * Makefile.in (FLAGS_TO_PASS): Define.
4173 (OBJDEPS): Define.
4174 (../cc1chill): Depend on $(OBJDEPS) $(C_OBJS).
4175 * Make-lang.in (cc1chill): Delete dependency on $(OBJS) $(BC_OBJS).
4176 (CHILL.mostlyclean): Use `mostlyclean' as recursive target.
4178 Sun May 8 13:05:00 1994 Per Bothner (bothner@cygnus.com)
4180 * Make-lang.in (cc1chill): Should not depend on libgcc.a.
4182 Thu May 5 18:58:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
4184 * decl.c (copy_lang_decl): New (dummy) function.
4186 Mon May 2 14:33:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
4188 * parse.y (sendaction): Fix thinko (in sense of condition).
4189 * tasking.c (build_receive_case_label): Another thinko.
4191 * parse.y (optsigdest): Force ignore_exprs to 0 while parsing
4192 the (signal-)name.
4194 * decl.c (build_chill_function_type): Don't call layout_type
4195 (since that may prevent parameter or result types being
4196 properly satisfied).
4197 * satisfy.c (satisfy): Layout FUNCTION_TYPEs.
4198 * parse.y (procmode): Call build_chill_pointer_type, rather
4199 than build_pointer_type (which incorrectly sets TYPE_SIZE).
4201 * parse.y (get_type_of): Handle TYPE_DECL (again).
4202 * parse.y (optresultspec): Call build_chill_reference_type, rather
4203 than build_reference_type (which incorrectly sets TYPE_SIZE).
4204 * parse.y (range_or_mode): Rename to plain range, since it
4205 no longer matches modename.
4206 * actions.c (chill_handle_case_label_range): New function, with
4207 functionality moved out of chill_handle_case_label.
4208 * actions.c (chill_handle_case_label): Handle here the case that
4209 the label_value is a TYPE_DECL (modename). Also clean up some.
4210 * typeck.c (build_chill_slice_with_length): Convert max_index
4211 to the type of min_value. (Old code broke on varying strings.)
4213 Sun May 1 13:53:36 1994 Doug Evans (dje@canuck.cygnus.com)
4215 * Makefile.in (BC_OBJS): Delete all references
4216 (OBJS): Cat ../stamp-objlist to get language independent files.
4217 (../cc1chill): Delete dependency on $(OBJS).
4218 * Make-lang.in (cc1chill): Depend on stamp-objlist.
4220 Sat Apr 30 14:50:15 1994 Per Bothner (bothner@kalessin.cygnus.com)
4222 * lex.h, lex.c: Remove lastiddecl.
4223 * lex.l (name_type_signal): Simplify. We no longer check for
4224 TYPENAME or SIGNALNAME (which was unreliable with two passes).
4225 Also rename to make_identifier.
4226 * parse.y: Cleaned up grammar to not need SIGNALNAME or TYPENAME.
4227 * Makefile.in (stamp-parse); One conflict fewer!
4228 * parse.y (rccase_label_flag): Moved to tasking.c.
4229 * parse.y (rccase_label): Move most of the logic to
4230 build_receive_case_label in tasking.c.
4231 * parse.y (sendaction): Re-write to not depend on SIGNALNAME.
4233 * parse.y (name): Do name lookup here (and not in location).
4234 * parse.y: Replace most uses of NAME by higher-level non-terminals:
4235 simple_name_string, name_string, defining_occurrence, or name.
4237 * tasking.c (build_receive_signal_case_label,
4238 build_receive_buffer_case_label): New functions, split out from
4239 build_receive_case_label.
4240 * tasking.c (build_receive_case_label): Change parameters
4241 and return type. Moved stuff here (from the parser).
4242 * tasking.c (struct rc_state_type): Removed had_errors.
4243 Return error_mark_node instead.
4244 * tasking.c (build_rccase_set_error), ch-tree.h: Removed.
4246 * expr.c (build_generalized_call): If func is a signal type,
4247 call build_signal_descriptor.
4249 * parse.y (arrayindex): Renamed to index_mode, to match Z.200.
4250 * parse.y (ioindexmode): Removed; use index_mode instead.
4251 * expr.c (build_generalized_call): If args is a RANGE_EXPR,
4252 we have either a slice or a range mode, depending on func.
4253 * parse.y (index_mode): If we got an 'expr', only allow a name,
4254 or a range mode.
4255 * parse.y (call): A slice with both end points can be a range
4256 mode, so defer handling to build_generalized_call (or index_mode).
4258 * typeck.c (build_chill_slice_with_length): Fix type-checking.
4259 * typeck.c (chill_novelty): Undo (part of) change of April 28:
4260 The novelty of a range mode is the novlety of the parent.
4261 * typeck.c (chill_root_mode): Don't return integer_type_node
4262 if argument has non-nil novelty.
4264 * decl.c (global_bindings_p): Return -1 as true, for the sake
4265 of variable_size (in ../stor-layout.c).
4267 Fri Apr 29 13:42:43 1994 Per Bothner (bothner@kalessin.cygnus.com)
4269 * parse.y: Remove TYPENAME and modename. These are now plain
4270 NAMEs. Modify parsing actions appropriately.
4271 * expr.c (build_generalized_call): Handle the case that
4272 TREE_CODE (func) == TYPE_DECL (as in a cast).
4273 * lex.l (name_type_signal): Never return TYPENAME.

4721 to be compatible with the N-value class, with suitable M and N.
4722 * typeck.c (build_chill_slice): Don't smash a void TREE_TYPE.
4723 (We don't need to, and it causes confusion.)
4725 * expr.c (build_compare_expr): Fix thinko. Add save_exprs.
4727 * expr.c (build_compare_expr): Fix a transcription bug
4728 (for converting NULL INSTANCEs). Also #include convert.h.
4730 * expr.c (compare_int_csts): New. Compare INTEGER_CSTs.
4731 Works even if their types have different TREE_UNSIGNED.
4732 * expr.c (finish_chill_binary_op): Moved code dealing with
4733 the comparison operators from here ...
4734 * expr.c (build_compare_expr): ... to new function here.
4735 Also, for discrete types, tries to Do The Right Thing, even for
4736 differing values of TYPE_PRECISION and TREE_UNSIGNED.
4737 the code from lay
4738 * ch-tree.h: Declare new functions.
4739 * typeck.c (valid_array_index_p): Various cleanups,
4740 including using new build_parse_expr.
4741 * parse.y: Use new build_compare_expr.
4743 * inout.c (build_chill_writetext): Handle REFERENCE_TYPE args.

4757 to get runtime index checking.
4758 * expr.c (build_chill_pred_or_succ): Fix cond tree
4759 to have consistent operand types.
4760 * typeck.c (valid_array_index_p): Change interface to pass
4761 validity conditions back on caller's TREE_LIST. We
4762 cannot link the conditions to anything which a
4763 layout_type routine will expand, since that will occur
4764 before the exception handler is set up.
4765 Change calls to valid_array_index_p also.
4767 Fri Mar 18 14:40:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
4769 * actions.c, except.c, loop.c, tasking.c: Call
4770 build_chill_function_call instead of the C-specific
4771 build_function_call.

4773 * loop.c (top_loop_end_check): Coerce library function arg.
4774 * convert.c, expr.c: Re-write to avoid calls to C-specific
4775 function build_unary_op (e.g. by calling build1 directly).
4777 * typeck.c (chill_equivalent): Change to force failure
4778 for non-matching integral types (even if not ranges).
4780 * typeck.c, ch-tree.h (build_chill_slice): Make non-static.
4781 * expr.c (varying_to_slice): Call build_chill_slice (and not
4782 build_chill_slice_with_length, which does bunches of range
4783 checking and does not allow the length to be zero).
4784 * convert.c (convert): Fix off-by-one error.
4785 * actions.c (chill_expand_array_assignment): Minor cleaning up.
4787 Fri Mar 18 00:12:48 1994 Per Bothner (bothner@deneb.cygnus.com)
4789 * decl.c (init_decl_processing): __lepowerset and __ltpowerset
4790 take *two* pointer parameters, not one.
4791 * satisfy.c (satisfy): Only call the appropriate layout routine
4792 if TYPE_SIZE is 0 (i.e. type hasn't already been laid out).
4793 * typeck.c (build_chill_slice_with_length): Fix Bill's previous fix.
4795 Thu Mar 17 17:29:43 1994 Bill Cox (bill@rtl.cygnus.com)
4797 * expr.c (build_chill_function_call): Give function call the correct
4798 type tree.
4799 * typeck.c (build_chill_slice_with_length): Restore dynamic range
4800 checking, so it doesn't obscure the CONSTANTness of the length.
4802 Wed Mar 16 17:23:31 1994 Per Bothner (bothner@kalessin.cygnus.com)
4804 * typeck.c (build_chill_slice), expr.c (chill_expand_expr
4805 [case CONCAT_EXPR]): Remove kludge setting slice size upper bound
4806 in TYPE_LANG_SPECIFIC, and restore kludge setting it in MAX_VALUE.
4807 * typeck.c (build_chill_slice): Use TYPE_MAX_VALUE of
4808 array_type if needed for size upper bound of slice_type.
4809 * expr.c (build_concat_expr): Improve calculation of size upper bound.
4811 * typeck.c (valid_array_index_p): Check compatibility using
4812 correct types.
4813 * typeck.c (build_chill_slice_with_length); For now revert
4814 calling valid_array_index_p on length. (It makes it harder
4815 to realize when the slice is constant length.)
4816 * expr.c (build_chill_indirect_expr): Minor tweak. (This
4817 seems to work around a weird C compiler bug. ??)
4819 * expr.c (build_chill_function_call): Cleanup so it doesn't
4820 call build_function_call (in c-typeck.c).
4821 * typeck.c, expr.c: Use build_chill_function_call instead of
4822 build_function_call (in c-typeck.c).
4824 * parse.y (discrete_mode): Move some of the rules from
4825 non_array_mode into new non-terminal.
4826 (arrayindex): Use discrete_mode (with NAME and TYPENAME) to
4827 avoid some misparses.
4828 * ch-tree.h (SLICE_PTR, SLICE_LENGTH): Removed; unused.
4829 * convert.c (digest_structure_tuple): Add missing parameter.
4830 * decl.c (comptypes): Remove unused prototype.
4831 * decl.c (build_chill_function_type): Handle NULL return_type
4832 correctly (convert to void_type_node).
4833 * decl.c (init_decl_processing): layout boolean_type_node *after*
4834 we've set it's TYPE_MIN_VALUE and TYPE_MAX_VALUE.
4836 Wed Mar 16 16:08:22 1994 Bill Cox (bill@rtl.cygnus.com)

4839 * convert.c (convert): Correct calculation of padding length.
4840 * decl.c (grok_chill_fixedfields): Move ignore_exprs test to
4841 parse.y where it belongs. This permits the removal of a kludge
4842 in make_process_struct.
4843 * lex.l, parse.y: Call to_global_level for several errors. Add
4844 code to output error in only one pass.

4846 March 8.
4847 (build_receive_case_end): Add Wilfried's check for errors.

4853 (expand_varying_length_assignment): call valid_array_index_p.
4854 rather than validate_varying_array_ref.
4855 * ch-tree.h: Fix prototype for valid_array_index_p.
4856 * expr.c (chill_expand_expr): Call build_chill_array_ref to get
4857 index validation.
4858 (build_hill_lower, build_chill_upper): Return value now inherits
4859 the novelty of the input parameter.
4860 (varying_to_slice): Use CH_NOVELTY macro rather than calling
4861 chill_novelty directly.
4862 * grant.c (newstring): Make len unsigned and cast xmalloc parameter
4863 to unsigned.
4864 (print_integer_type): Pass string value as APPEND's second parameter.
4865 (decode_decl): Pass a boolean expression as print_proc_tail's
4866 first parameter.
4867 (chill_finish_module_code): Make xmalloc's parameter unsigned.
4868 * lex.l: Pass sizes to xmalloc as unsigned ints. Pass second
4869 parameter to in_word_set as unsigned.
4870 * loop.c (build_loop_start): Check top_loop_end_check return value.
4871 * parse.y: Add casts to int for third do_decls parameter, fifth
4872 build_loop_iterator parameter, etc.
4873 * tasking.c (build_receive_case_end): Chack cond_stack before popping.
4874 * typeck.c (validate_varying_array_ref, chill_max_vary_array_index,

4877 array index is checked.
4878 (build_chill_slice): Restore old functionality where varying_to_slice
4879 is called to handle slices of varying arrays, rather than handling
4880 handling them here.
4881 (build_chill_slice_with_range, build_chill_slice_with_length):
4882 Check range limits for TREE_CONST before calling tree_int_cst_lt.
4883 Delete now-obsolete checks of constant indices.
4885 Mon Mar 14 17:26:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
4887 * parse.y (modeless_expr): New rule to allow ([...]) and (if...)
4888 to count as untyped_exprs. (This is not really permitted by the
4889 Blue Book, but has been requested by customers.)
4891 Thu Mar 10 10:11:02 1994 Bill Cox (bill@rtl.cygnus.com)
4893 * chill.texi: Document new command-line options.
4894 * expr.c (build_chill_num): Set unsigned parameter for
4895 type_for_size call correctly (unsigned for enums).

4898 * lex.l: Eat more whitespace.
4900 Thu Mar 10 09:41:37 1994 Bill Cox (bill@rtl.cygnus.com)
4902 * Makefile.in: Have rules to make parse.h, y.tab.c and other
4903 derived files. This allows the gcc/configure list of CHILL
4904 files machinery to work.
4905 * ch-tree.h (permanent_allocation): Add a parameter flag.
4906 * decl.c (finish_chill_function, finish_decl): Provide the
4907 new permanent_allocation flag.
4908 (poplevel): Return early, avoid a seg fault.
4909 * lex.l (NORMAL): Replace this whole state with the predefined
4910 INITIAL state. Force compilation state to global level after
4911 compiler directive error - prevents endless loop on error.
4912 (handle_use_seizefile_directive): Rewrite for readability.
4913 (chill_same_grant_file): Reindent.
4914 Generally handle whitespace differently.
4915 * regression.prpt: Print ten PR numbers per line. The report's
4916 getting too long.
4918 Wed Mar 9 09:58:51 1994 Bill Cox (bill@rtl.cygnus.com)
4920 * decl.c (do_decl): Suppress the string-assignment-condition
4921 error - it was too often seen.
4922 * expr.c (expand_chill_expr): In CONCAT_EXPR, when argument has a
4923 runtime-changing length (as in a slice), get the parent array's
4924 allocation size from its type tree.
4925 * typeck.c (build_chill_slice): Support VARYING arrays. Pass
4926 parent array's static allocation size along in the slice type.

4930 * lex.l (name_type_signal): Avoid dereferencing a NULL TRE_TYPE.
4932 Tue Mar 8 11:51:10 1994 Bill Cox (bill@rtl.cygnus.com)
4934 * expr.c (build_chill_sizeof): Fix typo in error msg, add
4935 some whitespace.
4936 * lex.l (name_type_signal): Add debug output.
4937 * parse.y (call): Allow EVENTNAME and BUFFERNAME parameters
4938 to a call, so that SIZE () works on them.
4939 * tasking.c (make_process_struct): Force ignore_exprs non-zero
4940 when processing a SEIZEd PROCESS declaration. This prevents
4941 grox-fixed_fields from returning a NULL, and indirectly protects
4942 the chill_integer_type_node tree from corruption.
4944 Mon Mar 7 19:14:05 1994 Bill Cox (bill@rtl.cygnus.com)
4946 * Makefile.in: Use the 'all' target to build the runtime
4947 library and chillrt0.o.

4950 chill.regress.cron: Move to utils subdirectory.
4951 * expr.c (build_chill_function_call): Mark the INOUT
4952 temporary so it doesn't get optimized into a
4953 register. Fixes the execute/inout.ch bug.
4954 * typeck.c (layout_chill_range_type): Restrict it
4955 from complaining about an empty string type's
4956 bounds (0:-1).
4958 Mon Mar 7 09:06:39 1994 Bill Cox (bill@rtl.cygnus.com)
4960 * Makefile.in (compiler): Restore this target.
4961 (OBJS, BC_OBJS): Delete unused variables.
4962 Add $(FLAGS_TO_PASS) to sub-make invocations.
4963 * ch_decomment.l, ch_makedepend, chill.patches, printf.c,

4968 * except.c (finish_handler_array): When computing address of
4969 the array ex_decl, don't call build_array_ref.
4971 Sat Mar 5 17:43:36 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
4973 * loop.c (declare_temps): Force powerset temp to memory.

4990 * inout.c (build_chill_writetext): Add handling of a REAL.
4991 * lex.l (INITIAL): Remove all code to discard 'header lines'.
4992 no longer needed.
4993 * parse.y (optheader): Remove - it's obsolete, as is the
4994 HEADEREL token definition.
4996 Fri Mar 4 09:41:18 1994 Bill Cox (bill@rtl.cygnus.com)
4998 * addtest: Fix suffix removal when suffix is .c186.
4999 * regression.sh: Allow for underscores on PR filenames.
5000 * typeck.c: Check in the rewrite mentioned earlier.
5002 Thu Mar 3 09:42:10 1994 Wilfried Moser (fs_moser at rcsw1h)

5016 push_extern_function and start_chill_functions.
5017 (convert_for_assignment): Check whether to generate runtime
5018 range-checking code. Handle reference_type in convert call.
5019 (chill_expand_assignment): Produce an INDIRECT_REF for a

5084 since we don't need it until we're testing.
5085 * addtest: Strip suffix from each input filename.
5086 * decl.c (do_decl): Correct error checking. Call
5087 string_assignment_condition for some of it.
5088 * tasking.c (build_gen_inst): Add ability to pass an integer

5093 name for correctness.
5095 Wed Feb 23 15:07:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
5097 New cleaner solution to the following problem:
5098 Chill allows an action to be followed by an ON-handler.
5099 But we don't know if an action has a handler until we've parsed
5100 its end, yet we want to generate extra code to set up an
5101 exception handling contour only if needed. The old solution
5102 would generate code for the action into an rtl sequence, and then
5103 splice in the exception-setup code if we later found we needed it.
5104 This has a few problems (for example it confuses the management
5105 of stack temporaries), and is ugly. Now that the compiler is 2-pass
5106 we have a cleaner solution: In pass 1, we remember which actions
5107 were followed by ON-handlers. In pass 2, we use this information
5108 to generate appropriate code before an action.
5109 * except.c (push_handler, pop_handler): In pass 1, set up data
5110 structures (global_handler_list) to remember if an action has an
5111 ON-handler. In pass 2, digest this information, and setup
5112 handler if needed.
5113 * except.c, actions.h (pop_handler): Take an extra int arg.
5114 * except.c (emit_setup_handler): New function, with code (moved
5115 from chill_start_on) to emit code before an action that has a handler.
5116 * except.c (except_init_pass_2): New function.
5117 * parse.y (pass1_2): Call except_init_pass_2 before pass 2.
5118 * parse.y (POP_UNUSED_ON_CONTEXT): Don't call pop_sequence.
5119 * parse.y: Invoke POP_UNUSED_ON_CONTEXT and POP_USED_ON_CONTEXT
5120 in pass 1 as well as pass 2.
5121 * parse.y (BEGIN ... END): Re-arrange logic to avoid block_stack
5122 (local to ../stmt.c) getting out of sync.
5123 * actions.c (push_action): Don't need to emit a NOP,
5124 now that we're no longer moving sequences around.
5125 * actions.c (push_action): Call push_handler even in pass one.
5127 Wed Feb 23 11:06:14 1994 Bill Cox (bill@rtl.cygnus.com)

5135 seg-faulting.
5137 Tue Feb 22 17:54:43 1994 Bill Cox (bill@rtl.cygnus.com)
5139 * Makefile.in: Use $(CC) rather than FLAGS_TO_PASS, which isn't
5140 defined. Build chill script differently, and build an install script.

5142 * actions.c (chill_expand_assignment): Change
5143 string_assignment_condition call.
5144 * ch-tree.h: Add prototype.

5737 Fri Jan 14 21:09:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
5739 * c-typeck.c, ch-actions.c, ch-convert.c, ch-decl.c, ch-except.c,
5740 ch-satisfy.c, ch-typeck.c: Undo all of initializer-related changes
5741 that Tiemann did earlier this month.
5742 * c-typeck.c (really_start_incremental_init): Save
5743 constructor_elements and (old value of) constructor_stack
5744 on constructor_stack, to allow for nested initializers.
5745 * ch-convert.c (digest_constructor): If we need a varying
5746 array, and have a constructor (for the array elements),
5747 make sure to use convert so that the constructor gets
5748 wrapped in an implicit record constructor.
5749 * ch-decl.c (do_decl): If there is no initializer for a
5750 varying array (or bitstring), create default constructor.
5752 * ch-expr.c (build_chill_lower): Fix thinko for ARRAY_TYPE.
5753 * ch-satisfy.c (safe_satisfy_decl): Make sure that we make
5754 original decl to check if we need to make an rtl.
5756 * ch-typeck.c (build_chill_array_ref_1), ch-tree.h: New function
5757 which does the actual work for build_chill_array_ref (which
5758 now just loops over an argument list).
5759 * ch-actions.c, ch-expr.c, ch-inout.c: Use build_chill_array_ref_1
5760 instead of build_chill_array_ref where appropriate.
5761 * ch-actions.c, ch-expr.c, ch-typeck.c: Make operand 1 of a
5762 VARY_ARRAY_REF is a single index, not an index list.
5764 * ch-grant.c (__init_list): Renamed to _ch_init_list, to
5765 avoid a conflict on the Alpha.
5767 Wed Jan 12 10:19:35 1994 Bill Cox (bill@rtl.cygnus.com)
5769 * ch-lex.l (WS): Add BS, VT and CR to definition of
5770 whitespace.
5771 (convert_number): Allow for uppercase hex digits.

5777 * ch-expr.c (build_chill_addr_expr): Add error message.
5778 * ch-grant.c (chill_finish_module_code): Avoid abort by
5779 giving the init_list constructor a type.
5780 (chill_finish_compile): Delete unused code.
5781 * ch-lex.l: Make most build_init_2 calls from the

5784 messages.
5786 Tue Jan 11 12:31:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
5788 * ch-expr.c, ch-typeck.c: Rewrite some instances of
5789 'struct ch_class class = chill_expr_class (expr);' to
5790 'struct ch_class class; class = chill_expr_class (expr);'
5791 to work around a bug in /usr/ucb/cc on SunOS4.
5793 Mon Jan 10 18:29:36 1994 Bill Cox (bill@rtl.cygnus.com)
5795 * ch-actions.c (chill_convert_for_assignment): Avoid seg fault.
5796 * ch-expr.c (expand_packed_set): Add new parameter to pass
5797 set's minimum ordinal value. Fix loop invariant problem.
5798 (fold_set_expr): Change to add new parameter to
5799 expand_packed_set call.
5800 * ch-grant.c: Move extern declaration to ch-tree.h.

5816 Also, fix some bugs for bitstrings (with ranges).
5818 (Patches from Tiemann.)
5819 * ch-convert.c (convert1): New function to force TREE_TYPE.
5820 (convert): Use convert1 where appropriate.
5821 * ch-typeck.c: Formatting change.
5822 * ch-parse.y (build_chill_constructor): Fix thinko.
5824 * ch-expr.c (varying_to_slice): If array is not referable,
5825 call save_expr on it, rather than stabilize_reference.
5826 * ch-satisfy.c (safe_satify_decl, for CONST_DECL):
5827 Don't force value to value class if mode is not explicitly
5828 specified. Also, make sure convert etc is only done once.
5830 Sat Jan 8 16:37:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
5832 * ch-decl.c (build_chill_function_type): Don't call
5833 build_function_type, because it does hash canonicalization,
5834 which once in a while looses badly.
5835 * tree.c (build_function_type): Remove no-longer-needed test
5836 for doing_chill_thang.
5838 * ch-tree.h (CH_DERIVED_FLAG): New flag.

5841 'class' as a first-class value.
5842 (CH_ROOT_RESULTING_MODE): Replaced by CH_ROOT_RESULTING_CLASS.
5843 * ch-typeck.c (chill_expr_class): Change interface to return
5844 a struct ch_class.
5845 (chill_compatible, chill_compatible_classes): Update accordingly.
5846 (chill_root_resulting_mode): Replace by ....
5847 (chill_root_resulting_class): ... new function.

5849 * ch-decl.c (layout_enum): Mark enum values with CH_DERIVED_FLAG.
5850 * ch-lex.l (string_or_int): Rename to string_or_char.
5851 * ch-lex.l (build_chill_string, string_or_char, convert_bitstring,
5852 convert_float, convert_number): Set CH_DERIVED_FLAG for literals.
5853 * ch-expr.c (finish_chill_binary_op): Use convert_to_class.
5854 * ch-satisfy.c (safe_satisfy_decl): For CONST_DECL, make sure
5855 DECL_INITIAL gets set to result of convert.
5856 Also, clear CH_DERIVED_FLAG for SYN value.
5857 * expr.c (store_constructor): If a [power]set is exactly one
5858 word long, use single-word move.
5860 Sat Jan 8 08:38:29 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5862 * c-typeck.c (chill_initializer_constant_valid_p): Fix typo.
5864 Wed Jan 5 05:18:46 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5866 * ch-typeck.c (build_chill_slice_with_length): Test that ARRAY is of
5867 ARRAY_TYPE before assuming so. Also, subtract 1 from LENGTH in
5868 computation of SLICE_END.
5870 * ch-typeck.c (chill_location): Treat CONSTRUCTORs like STRING_CSTs.
5872 * ch-expr.c (build_chill_indirect_ref): Handle MODE == NULL_TREE.
5874 * ch-expr.c (fold_set_expr): Handle OP1 == NULL_TREE (which happens
5875 for unary set operations).
5877 * ch-expr.c (build_chill_array_expr): Take new argument FORCE. All
5878 callers changed. All callers changed.
5880 * ch-convert.c (digest_structure_tuple): Handle SELECTED_VARIANT
5881 being NULL_TREE until we've started walking the list of values via
5882 the loop over VARIANTs.
5884 * ch-parse.y (build_chill_constructor): If we see an IDENTIFIER_NODE,
5885 treat it as an enum value (and hence constant). Also, only set
5886 TREE_STATIC if the constructor is indeed constant.
5887 * c-typeck.c (chill_initializer_constant_valid_p): If we see a
5888 VAR_DECL, test the TREE_CONSTANT field of the DECL_INITIAL, don't
5889 recurse on the DECL_INITIAL.
5891 Wed Jan 5 01:24:50 1994 Bill Cox (bill@cygnus.com)
5893 * Makefile.in: Add CHILL to LANGUAGES variable.
5894 * ch-actions.c (check_range): Call build_binary_op instead of
5895 fold, build to get the common types chosen.
5896 (cond_range_exception, cond_overflow_exception,
5897 cond_type_range_exception): Delete, obsolete.
5898 (chill_convert_for_assignment): Enable this, get particular
5899 about when to generate rangecheck code.
5900 * ch-expr.c (build_chill_function_call): Sketch in where to
5901 perform chill_convert_for_assignment on actual parameters.
5902 (build_chill_addr_expr): Correct compiler warning.
5903 * ch-loop.c (build_chill_iterator): Add runtime check for
5904 negative loop step expression.
5905 * ch-tree.h: Add prototype.
5906 * ch-typeck.c (chill_max_vary_array_ref): Correct misunderstanding.
5907 A varying array's length field counts the NUMBER of active array
5908 array entries, not the byte-length of them.
5910 Tue Jan 4 17:57:39 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5912 * ch-decl.c (do_decl): Call `suspend_momenary' if the
5913 converted constructor must live on the permanent_obstack.
5914 * ch-convert.c (convert): When building a new SET_TYPE
5915 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5916 * c-typeck.c (chill_initializer_constant_valid_p): Handle VAR_DECLs.
5918 * ch-typeck.c (chill_location): CONSTRUCTORS that are static
5919 are locations.
5920 * ch-satisfy.c (safe_satisfy_decl): Convert DECL_INITIAL of CONST_DECL
5921 on permanent_obstack if necessary.
5923 * ch-convert.c (digest_structure_tuple): When building a new SET_TYPE
5924 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5926 * ch-decl.c (do_decl): Fix handling of REFERENCE_TYPEs which
5927 the patch below helped to mess up.
5929 * ch-expr.c (build_chill_arrow_expr): Call `mark_addressable'.
5930 (build_chill_addr_expr): Take new argument ERRORMSG.
5931 All callers changed. Also, call `build_chill_addr_expr' where
5932 we used to call `build1 (ADDR_EXPR, ptr_type_node, ...)' since
5933 that now calls `mark_addressable' automagically.
5935 * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.
5936 This is needed because variables may appear in initialization
5937 statements, and their DECL_INITIALs are their values at
5938 initialization time.
5939 * ch-convert.c (digest_structure_tuple,digest_constructor): Changed
5940 to handle VAR_DECLs as initializers.
5942 * ch-convert.c (digest_structure_tuple): Copy elements of INITS so
5943 they aren't destroyed for later use.
5945 Tue Jan 4 15:25:30 1994 Bill Cox (bill@cygnus.com)
5947 * ch-expr.c (chill_expand_expr): Correct check-range lo_limit
5948 parameter for varying_array_ref calculations.
5949 (build_chill_indirect_ref): Prevent seg fault due to syntax error.
5950 * ch-typeck.c (build_chill_slice_with_range): Correct issuance
5951 of bogus error in votrics.
5952 (build_chill_slice_with_length): Change for debug tracability.
5954 Tue Jan 4 02:43:37 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5956 * ch-convert.c (digest_structure_tuple): Fix phasing problem in
5957 handling variant record initializers.
5958 (various places): Change `pop_init_level' calls to match
5959 `push_init_level' wrt implicit variable.
5961 * ch-typeck.c (build_chill_slice): Convert the dynamic max index to
5962 `integer_type_node' before using it in comparisons. FIXME: should
5963 this be done in `chill_max_vary_array_index' by default?
5965 Tue Jan 4 00:24:14 1994 Bill Cox (bill@cygnus.com)
5967 * ch-actions.c: Fix comments.
5968 * ch-parse.y: Define caseaction_flag.
5969 (caseaction): Create new caseaction_flag node at the start,
5970 then free it at the end. Check it before the ELSE code.
5971 (expanded_case_label): Check the flag here. If set in either
5972 place, generate a jump to the end of the case.
5973 * ch-typeck.c (build_chill_slice_with_length,
5974 build_chill_slice_with_range): Add lots of compile-time
5975 parameter range checking.
5977 Mon Jan 3 21:49:04 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5979 * ch-convert.c (digest_structure_tuple): Call `push_init_level' with
5980 implicit==0 everywhere, not 1.
5981 (digest_constructor): Ditto.
5983 * ch-actions.c (check_range): Permit limits to be NULL_TREE.
5984 Also, hack out some dead code.
5985 * ch-typeck.c (build_chill_slice): Check varying and non-varying
5986 slice constructs for range failures.
5987 (build_chill_slice_with_range): Reindented, but not changed.
5989 * ch-typeck.c (chill_max_vary_array_index): New function.
5990 * ch-expr.c (chill_expand_expr): Call it.
5992 * ch-decl.c (var_data_id, var_length_id): New variables.
5993 (init_decl_processing): Initialize them. All calls to
5994 get_identifier (VAR_LENGTH or VAR_DATA) are now replaced
5995 by references to these variables. This simplifies the code
5996 w/o obscuring anything.
5998 Mon Jan 3 21:24:44 1994 Bill Cox (bill@cygnus.com)
6000 * c-typeck.c: Fix comment.
6001 * ch-actions.c (chill_expand_assignment): Error assigning to
6002 READONLY location. (PR_3903) Pass filename, linenumber
6003 to setbitpowerset runtime routine.
6004 * ch-decl.c (init_decl_processing): Add filename, linenumber
6005 parameters to setbitpowerset prototype.
6006 * ch-expr.c (build_chill_function_call): Error when passing a
6007 READonly location as a LOC or INOUT parameter.
6008 * ch-parse.y (mode): Correct code marking type as readonly.
6010 Mon Jan 3 19:03:55 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6012 * ch-actions.c (chill_expand_assignment): Disable code that defeats
6013 building varying array references.
6014 * ch-expr.c (chill_expand_expr): Add rangecheck code to
6015 VARY_ARRAY_REF case.
6016 * ch-typeck.c (build_chill_array_ref): Don't call an `expand_'
6017 function (in this case, `validate_varying_array_ref') when we're
6018 doing a `build_' operation.
6020 * ch-typeck.c (validate_varying_array_ref): Simplify interface
6021 since INDEX parameter can never meaningfully be an INDEXLIST.
6022 * ch-actions.c (expand_varying_length_assignment): Caller changed.
6024 Mon Jan 3 07:29:45 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6026 * ch-typeck.c (build_chill_cast): Set TREE_CONSTANT on NOP_EXPRs.
6027 * ch-convert.c (digest_structure_tuple): Switch to permanent_obstack
6028 if we need to build a CONSTRUCTOR for a SET_TYPE initializer.
6029 (digest_structure_tuple): If TREE_VALUE (VALUE) == NULL_TREE, don't
6030 call CH_COMPATIBLE or try to convert it to TREE_TYPE (FIELD). This
6031 can happen when constructors are output incrementally.
6032 * c-typeck.c (initializer_constant_valid_p): Handle SET_TYPEs.
6033 * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
6034 CONSTRUCTORS.
6036 Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6038 * ch-convert (digest_structure_tuple): Handle SET_TYPEs. Also, call
6039 `convert' so we can handle INSTANCE types (and other anomolies)
6040 correctly.
6042 * ch-convert.c (digest_structure_tuple): Fixed variant
6043 structure initialization. Also fixed a typo (TYPE_NAME
6044 was being used on a FIELD_DECL instead of DECL_NAME).
6045 * c-typeck.c (initializer_constant_valid_p): Pass missing
6046 ENDTYPE argument on recursive call.
6047 (set_init_field): New function, needed by ch-convert.c change above.
6049 * ch-decl.c (layout_chill_variants): Added a FIXME next to an
6050 almost certain typo.
6052 * ch-expr.c (build_chill_arrow_expr): Call `build1' and set
6053 TREE_CONSTANT for static references.
6054 * ch-except.c (chill_start_on): Change calls to
6055 `build_unary_op' (which is C-specific) to `build_chill_arrow_expr'
6056 which has CHILL semantics.
6057 * ch-convert.c (convert): Ditto (albeit in some disabled code).
6059 Sat Jan 1 21:26:43 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6061 * ch-satisfy.c (safe_satisfy_decl): Reorder conditional test of
6062 TREE_CODE of DECL in case it's altered by actions in the switch.
6064 * ch-satisfy.c (satisfy): Undo abort added earlier on 1 Jan. CVS log
6065 mentions where to find code that triggers this case.
6067 * ch-actions.c (adjust_parm_or_field): Handle CONSTRUCTORS here as
6068 well.
6070 * ch-convert.c (digest_structure_tuple): Push to permanent_obstack if
6071 we're dealing with a CONSTRUCTOR that is TREE_PERMANENT.
6072 (digest_constructor): Ditto.
6074 Sat Jan 1 10:29:19 1994 Michael Tiemann (tiemann@blues.cygnus.com)
6076 * ch-parse.y (handleraction,resultaction,assignaction,call): Modified
6077 so that CONSTRUCTORS are properly handled before being used.
6079 * ch-convert.c (chill_start_init): New function. All callers to
6080 `start_init' changed to call this function instead.
6081 (digest_struct_tuple): Defend against initialization machinery
6082 mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
6083 IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
6084 needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
6085 can be refered to throughout the compilation unit. Also remove an
6086 extraneous call to `process_init_element' erroneously added to the
6087 variant record sub-loop.
6088 (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
6089 CONSTRUCTORS of SET_TYPE.
6090 * ch-parse.y (build_chill_constructor): Refix typo. Also set
6091 TREE_STATIC if at top level.
6093 * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
6094 TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
6095 should have been called.
6097 * ch-convert.c (digest_struct_tuple): Restore code which tracks
6098 field initializations so that the compiler can deduce what variant
6099 initializations to assume.
6101 * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
6102 when we push into a scope that has a DECL with a CONSTRUCTOR as its
6103 DECL_INIT.
6105 * ch-parse.y (build_chill_constructor): Change the name of the
6106 parameter to something more meaningful. Fix typo. Also, handle case
6107 where element is an untyped CONSTRUCTOR.
6109 * ch-except.c (finish_handler_array): Set TREE_CONSTANT on
6110 constant ADDR_EXPRs.
6111 (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT
6112 on JBUF_REF (instead of calling `build1' which does not).
6114 * ch-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
6116 * ch-typeck.c (chill_expand_tuple): Deleted.
6117 * ch-parse.y (primval rule): Don't call `chill_expand_tuple';
6118 instead, use initialization machinery for CONSTRUCTORS that
6119 come through here.
6120 * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
6121 that are created here.
6122 * ch-satisfy (satisfy): Abort in case we would have called
6123 chill_expand_tuple. FIXME: some other code is needed here,
6124 but I don't know what yet.
6126 * ch-parse.y (build_chill_constructor): New function to
6127 propagate TREE_CONSTANT bits to CONSTRUCTORS.
6128 (untyped_expr rule): Use it.
6129 (primval rule): Use it.
6131 * ch-decl.c (do_decl): Call `finish_init'.
6132 * ch-convert.c (convert): If we spontaneously create a CONSTRUCTOR in
6133 this function, make sure the initialization machinery is set up.

6136 missing prototypes.
6138 Fri Dec 31 11:31:01 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6140 * ch-grant.c (chill_finish_module_code): Mark ADDR_EXPR built by hand
6141 as being TREE_CONSTANT. Otherwise it gets bounded by the initializer
6142 code.
6144 * ch-decl.c (do_decl): Change in CONSTRUCTOR handling due to...
6145 * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
6146 rewritten to work with GCC's initialization code. The basic change
6147 was to keep the initializers in sync with the initialization
6148 machinery that `process_init_element' imposes. Both of these
6149 functions now return `void'.
6150 * ch-convert.c (convert): Changed calls to `digest_...' functions.
6152 FIXME: the code handling UNION_TYPE (and variant records) has not
6153 been tested yet.

6164 * ch-parse.y: Cleanup handling of RETURN actions, to distinguish
6165 a RETURN without a value (which cannot have an exception
6166 handler) from a RETURN with a value (which can). Eliminate
6167 some shift/reduce and reduce/reduce conflicts.
6169 Thu Dec 30 17:42:32 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6171 * ch-inout.c (build_chill_writetext): Deal with 2 cases where
6172 types returned from `type_for_size' are not expected. FIXME.
6173 * ch-decl.c (init_decl_processing): Mark `char_type_node' unsigned.
6174 This is required when range checking is enabled.
6176 Thu Dec 30 14:28:25 1993 Bill Cox (bill@rtl.cygnus.com)
6178 DELAY CASE works now.
6179 * ch-decl.c (init_decl_processing): Move rest of tasking-related

6198 * ch-expr.c (build_chill_indirect_ref): Revert change which
6199 failed full regression testing.
6200 * ch-lex.l (name_type_signal): Add debug output.
6201 * ch-parse.y (structured_variable): Add a debug variable.

6216 becoming a seg fault.

6218 * ch-loop.c: Delete/correct comments.
6219 * ch-parse.y (delaycaseaction): Add push/poplevel calls. Turn 'sorry'
6220 into rough draft of actual code.
6221 (delayaction): Don't make a new scope here, use get_unique_identifier
6222 instead.
6223 (locdec): process event decls here, too.
6224 (mode): Add code to forbid READonly EVENT and BUFFER decls. Delete
6225 code which required EVENTs and BUFFERs to be declared at global scope.
6226 (simple_name_string): Add an EVENTNAME.
6227 * ch-satisfy.c (safe_satisfy_decl): Prevent a syntax error from
6228 becoming a seg fault.
6229 * ch-tasking.c (tasking_setup): Add the event queue's max. length
6230 as the 'entry_point' parameter in the list.
6231 (build_receive_case_start, build_receive_case_label): Defer
6232 calling runtime routine until we know whether we have a signal

6242 * gcc.c (CHILL SPECS): Delete references to -M -MM -MD -MMD
6243 options. Delete C-specific defines. Disable piping from
6244 pre-processor to cc1chill (even if -pipe is specified), since cc1chill
6245 rewinds its input for its second pass. Piping still works
6246 from cc1chill to as.
6248 Thu Dec 23 12:31:55 1993 Bill Cox (bill@rtl.cygnus.com)
6250 * ch-tasking.c (decl_tasking_code_variable): Assure that the
6251 tasking_code variable is allocated on the permanent obstack.
6252 (tasking_setup): Lots of changes - handle EVENT/BUFFER max.
6253 queue length (passed as the entry_point parameter).
6254 Other changes to variable names to increase 'self-documentation'
6255 the only kind GNU CHILL will get, for a while..
6257 Wed Dec 22 10:46:31 1993 Bill Cox (bill@rtl.cygnus.com)
6259 * ch-decl.c (do_seize): Delete - it's unused. Fix comments.
6260 * ch-loop.c (build_chill_iterator): Convert BY expression
6261 so loop involving a SET works. Additional errors generated
6262 for numbered SET expression as start or end expression.
6263 * ch-tree.h: Prototypes for future DELAY functions.
6264 * ch-typeck.c: Standard indentation.
6266 Tue Dec 21 15:30:57 1993 Per Bothner (bothner@kalessin.cygnus.com)

6283 * ch-tree.h (CH_EQUIVALENT): Re-defined to use chill_equivalent.
6285 * dbxout.c (dbxout_type): Output the type attribute "@S;" to
6286 distinguish a string from a char array, and to distinguish a
6287 bitstring from regulat (power)set. (Needed for Chill.)
6288 * dbxout.c (dbxout_type): Only check for baseclasses in
6289 type.binfo is a vector. (It is used in Chill for tagged unions.)
6291 Fri Dec 17 09:56:07 1993 Bill Cox (bill@rtl.cygnus.com)
6293 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,

6311 * ch-tree.h: Fix prototypes.
6312 * ch-typeck.c (smash_dummy_type): Handle all four kinds of LANG_TYPE

6327 Tue Dec 14 15:41:32 1993 Per Bothner (bothner@kalessin.cygnus.com)
6329 * ch-decl.c (push_scope_decls): Re-arrange so that normal
6330 (non-seize) declarations are proclaim_decl'd *before* we
6331 handle the ALIAS_DECLs for seizes. The advantage is
6332 that we can now test for (an approximation) to the
6333 'seizeable' concept, thus avoiding duplicate definitions
6334 when a module has both GRANTs and SEIZE ALL.
6336 * ch-expr.c (build_chill_arrow_expr): No longer re-write
6337 addr-of-conversion to pointer-conversion-of-addr.

6345 * ch-tree.h (chill_root_resulting_mode): Fix typo (missing '_').
6347 * ch-expr.c (finish_chill_binary_op): Use CH_ROOT_RESULTING_MODE
6348 macro (which works on expressions), rather than CH_RESULTING_MODE
6349 (which works on modes, and isn't quite correct).
6350 * ch-tree.h (CH_IS_BOUND_REFERENCE_MODE): New macro.
6351 * ch-typeck.c (chill_read_compatible, chill_compatible):
6352 Use the new macro, which handles NEWMODEs of PTR correctly.

6354 dynamic-length array (and string) types (e.g. slices).
6355 * ch-typeck.c (chill_root_mode): If the mode has a Novelty,
6356 just return it as is. (This is still not 100% correct for
6357 NEWMODE of RANGEs, but is close enough.)
6359 Mon Dec 13 16:27:06 1993 Bill Cox (bill@rtl.cygnus.com)
6361 * ch-parse.y (locdec): Avoid passing IDENTIFIER_NODEs to

6376 in the buffer decl tree.
6377 (build_buffer_descriptor): Real, working version.

6397 for bitstring constants.
6398 * ch-typeck.c (chill_novelty): The novelty of an (unnamed)
6399 range mode is that of its parent mode; the novelty of READ M
6400 is that of M.
6402 Sat Dec 11 15:14:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
6404 * ch-expr.c (varying_to_slice): Call stabilize_reference
6405 rather than save_expr.
6406 * ch-typeck.c (build_chill_slice): Don't emit warning
6407 if array is a SAVE_EXPR (it is effectively referable).
6408 * ch-typeck.c (chill_root_resulting_mode): Handle
6409 correctly the case that one operand is DERIVED and one is VALUE.

6473 modes for similarity - specifically support calling chill_similar
6474 BEFORE the modes have been satisfied (needed by proclaim_decl).
6475 * ch-decl.c (proclaim_decl): Allow duplicate definitions
6476 of set elements of similar set modes.
6478 * ch-parse.y (caseaction): Call language-independent

6484 * ch-actions.c (cond_range_exception,

7010 * ch-expr.c (allocate_memory, allocate_global_memory):
7011 Check for invalid parameters, issue errors.
7012 * expr.c (store_constructor): Calculate bitlength, startrtx
7013 and endrtx of powerset correctly. Define targetx, use it

7059 * ch-tasking.c: Replace last calls to get_tasking_code with
7060 working references to DECL_TASKING_CODE_DECL.

7064 * ch-satisfy.c (safe_satisfy_decl): Satisfy the hidden tasking
7065 code variables associated with a process or signal.
7066 * ch-tasking.c (build_gen_inst, build_gen_ptype): Use the decl's
7067 tasking_code_decl pointer, rather than trying to look it up
7068 in the hash table or linked scope list.
7070 Wed Oct 20 09:52:44 1993 Bill Cox (bill@rtl.cygnus.com)
7072 * ch-actions.c (lookup_and_handle_exit): Only output error message

7079 generate_tasking_code_variable calls, plus a little glue.
7080 (push_extern_process): generate tasking_code_variable as local
7081 static variable, point the process' function_decl at it for later
7082 reference by build_start_process.
7083 (print_mode): Use CHILL upper-case convention to print modes.
7084 * ch-lex.l: Must initialize tasking-related trees to NULL at start
7085 of each pass, or we lose the fact that the user did or did not
7086 specify a value for each of them.
7087 * ch-parse.y (check_end_label, action, exceptlist): Only output
7088 error message in pass 1.
7089 (sendaction): Add comments.

7092 easier non-symbol-table access later.
7093 * ch-tasking.c (generate_tasking_code_variable): Do work in both
7094 passes, using do_decl so we can pass the pass 2 value of the
7095 process_type or signal_code to it. Only update the process_type
7096 if the incoming pointer isn't null and pass == 2. Use a new
7097 parameter to know whether to include an init expression.
7098 (build_process_header): Attach tasking-code_variable to process
7099 function_decl for easy access later, not through the hash table.

7114 generation for decls to not use DECL_ASSEMBLER_NAME.
7115 * ch-decl.c: Set DECL_ASSEMBLER_NAME to DECL_NAME.
7116 This matches C, and allows dbxout to emit proper user-level names.
7117 (It would be cleaner to fix dbxout to use DECL_NAME ...)
7118 * ch-decl.c (outer_decls): New global list of the decls granted
7119 into the outer scope.
7120 (pop_module): Change code that grants into outer scope accordingly.

7135 * ch-tree.h: Restore old version.
7136 * ch-expr.c (finish_chill_binary_op): Convert TRUNC_DIV_EXPR
7137 to RDIV_EXPR if an operand is floating. (This functionality
7138 got dropped when hacking finish_chill_binary_op).
7140 * ch-actions.c (build_chill_case_expr): Set type to NULL_TREE.
7141 not error_mark_node.
7142 * ch-actions.c (chill_expand_assignment): Allow such borderline
7143 constructs as: LHS OR:= [X].
7144 * ch-convert.c (convert): Hande CASE_EXPR (and COND_EXPR)

7146 * ch-decl.c (do_decl): Remove CONSTRUCTOR kludge.
7147 * ch-typeck.c (chill_compatible): Allow expr to have NULL mode
7148 if it's a CASE_EXPR or COND_EXPR (and not just CONSTRUCTOR).

7160 the module_init_list, for chill_finish_compile's possible use.
7161 (chill_finish_compile): Rename variables for clarity, add
7162 commented-out code as example for assignment of module address to its
7163 init_list entry.
7165 Sun Oct 17 15:16:54 1993 Bill Cox (bill@cygnus.com)
7167 * ch-convert.c: Move semicolon to separate line - easier to see.
7168 * ch-decl.c (do_decl): Handle untyped_expr initializers by
7169 simply using the variable's declared type - no compatibility
7170 check can be made if the expression has no type.
7171 * ch-expr.c (expand_packed_set): Fix endless loop - increment
7172 the loop variable.
7173 (fold_set_expr): Fix two other endless loops by passing
7174 correct parameters to unpack_set_constructor.

7345 seg fault.
7346 * ch-expr.c (finish_chill_binary_op): Mode access to TREE_CODE

7387 ch-convert.c (convert): Use it.
7388 * ch-typeck.c (build_chill_slice): Take length rather than upper
7389 bound. This makes it easier to recognize that A(X UP LENGTH)
7390 really has fixed length. Also, if the argument is string,
7391 mark the slice as a string too. Also, handle varying strings.
7393 * ch-typeck.c (conflate_singleton_strings): New global.
7394 * ch-typeck.c (chill_similar): If conflate_singleton_strings is
7395 set (as it currently is), allow CHARS(1)/BOOLS(1) to be similar

7404 * ch-actions.c (chill_expand_assignment): Convert 'LHS OP := RHS'
7405 to 'LHS := LHS OP RHS' (using stabilize_reference on LHS).
7406 Also, call save_expr on RHS if a multiple assignment.
7407 * ch-parse.y (assignaction): Therefore, no longer need to call
7408 stabilize_reference on RHS.
7409 * ch-typeck.c (build_chill_modify_expr), ch-tree.h: Remove

7421 * ch-satisfy.c (satisfy): Don't gag on string_index_type_dummy,
7422 * ch-tree.c (build_string_type): Pass string_index_type_dummy as
7423 the parent type of the index range.
7424 * ch-typeck.c (layout_chill_range_type): Recognize and handle
7425 string_index_type_dummy - specifically allow an empty range.
7427 Wed Sep 29 13:36:23 1993 1993 Bill Cox (bill@cygnus.com)
7429 * ch-convert.c (convert_to_reference): Check for loc-identity
7430 mismatches correctly (and remove one of those chill_compatible
7431 calls).
7432 * ch-decl.c (decl_tasking_code_var): New function, called from
7433 push_extern_process and push_extern_signal.
7434 * ch-parse.y (end_function): Delete parameter. Check current_function_decl
7435 whether it's actually a process, and whether it has parameters.
7436 Make Michael's change simplifying the pass 2 test, preventing a seg
7437 fault.
7438 (procedure, process): Change calls to end_function, remove
7439 code saving value from build_process_header. Delete redundant chill_
7440 phrases from some function calls.
7441 * ch-tasking.c: Remove some redundant _chill phrases from function
7442 names.
7443 * ch-tree.h: Remove some redundant _chill phrases from function
7444 names. Add the CH_VARYING_ARRAY_TYPE macro, call it from
7445 all relevant places.
7446 * ch-typeck.c: Use the new macro. Cast TREE_CODEs to chill_tree_code.
7448 Wed Sep 29 13:07:43 1993 Per Bothner (bothner@kalessin.cygnus.com)
7450 * ch-convert.c (convert_to_reference): Remove redundancies.
7451 * ch-convert.c (convert): Handle convert_to_reference
7452 with a recursive convert call.
7453 * ch-decl.c (do_decl): Add missing compatibility-checking
7454 of initializer (don't depend on convert).
7456 Tue Sep 28 00:02:25 1993 Per Bothner (bothner@kalessin.cygnus.com)
7458 * ch-tree.h (CH_LOCATION_P): New macro.
7459 * ch-typeck.c (layout_chill_range_type): Fix call to
7460 type_for_size, when figuring out a defaulted parent type.
7461 * ch-expr.c (build_chill_lower, build_chill_sizeof): Check
7462 for TREE_CODE_CLASS != 't' rather than == 'd'.
7463 * ch-expr.c (build_chill_function_call): Use CH_LOCATION_P
7464 to check for location, rather than TYPE_CODE_CLASS == 'd'.
7466 * ch-tree.c (build_string_type): Make 2-pass safe. Also,
7467 change parameter to be length, not index type.
7468 * ch-parse.y (mode2), ch-expr.c (build_concat_expr), ch-lex.l
7469 (build_chill_string): Modify callers of build_string_type accordingly.
7470 * ch-lex.l (check_newline): Don't look for # directive inside a
7471 C-style comment.
7472 * ch-grant.c (grant_array_type): Make more robust for char-
7473 and bit-strings (allow non-constant sizes). Change parameters
7474 and return types. (raw_decode_mode): Use grant_array_type
7475 for bitstrings. (otherwise): Fix grant_array_type callers.
7477 Mon Sep 27 16:57:57 1993 Per Bothner (bothner@kalessin.cygnus.com)
7479 Remove changes of Sep 15.
7480 * ch-tree.h (CH_SINGLETON_DOMAIN): Removed.
7481 * ch-typeck.c (chill_similar): Don't allow a singleton
7482 powerset to be similar to its domain.
7483 * ch-convert.c (convert_to_boolean): Don't convert a singleton
7484 SET_TYPE constructor to a Boolean.
7486 * ch-actions.c (chill_expand_assignment): Handle IN_EXPR on
7487 LHS of assignment, which is what we're current (temporarily?) using.
7489 Mon Sep 27 06:01:57 1993 Bill Cox (bill@rtl.cygnus.com)
7491 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,
7492 ch-grant.c, ch-inout.c, ch-parse.y, ch-satisfy.c,
7493 ch-tasking.c, ch-tree.c, ch-tree.h, ch-typeck.c:
7494 -Wall cleanup. Add prototypes where missing.
7495 Delete unused variables. Cast uses of tree_codes
7496 to chill_tree_code, which they are.
7498 Sun Sep 26 13:09:57 1993 Bill Cox (bill@rtl.cygnus.com)
7500 * ch-decl.c (do_decl): Save initializer in pass zero
7501 case also.
7502 * ch-lex.l: Fix comments, indentation.
7503 * ch-parse.y: Standardize error messages to use
7504 uppercase for CHILL keywords rather than quoting them.
7505 Suggestion from docs department.
7506 * ch-tasking.c: Pervasive changes to get processes to
7507 compile and START.
7508 * ch-tree.h: Delete prototypes for functions whic
7509 I made static inside ch-tasking.c.
7511 Sun Sep 26 02:40:02 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7513 * ch-lex.l (yywrap): Call `check_newline' in case the file
7514 started with a line directive.
7516 Sat Sep 25 13:54:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
7518 * ch-decl.c: Expand pre-amble comment.
7519 * ch-decl.c (struct scope, push_module): Use new field
7520 tail_chain_module to build child-module list in order.
7521 (Just to make compiler debugging a little less confusing.)
7523 * ch-decl.c (struct scope): New field weak_decls.
7524 * ch-decl.c (find_implied_types): New interface. Now pre-pend
7525 new enum types to a given input list. This makes it easier to
7526 avoid duplicates, which should at least be more efficient.
7527 Also, handle FUNCTION_DECL.
7528 * ch-decl.c (bind_saved_names): Removed. Distribute its
7529 functionality over new functions (push_scope_decls, pop_scope_decls,
7530 build_implied_names, bind_sub_modules). The goal (which seems to
7531 have been more-or-less attained) was to fix weak name handling.
7532 * ch-decl.c (poplevel): Use new function pop_scope_decls.
7534 * ch-tasking.c (build_signal_struct, build_tasking_message_type):
7535 Use build_decl directly, rather than grok_chill_fixedfields
7536 (which depends on ignore_exprs and has more overhead).
7537 * ch-tasking.c (build_signal_struct): Construct the type
7538 only in pass 1.
7539 * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
7540 than build_array_ref (which does C-specific "optimizations").
7541 (Hence move my_build_array_ref up earlier in the file.)
7543 Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7545 * ch-tasking.c: Declare static variable `void_ftype_void'.
7546 (chill_tasking_init): Initialize `void_ftype_void' here.
7547 (build_tasking_struct): Use, don't declare `void_ftype_void'.
7548 (generate_tasking_code_variable): Call `do_decl', not
7549 `decl_temp1' to declare TASKING_CODE_NAME.
7550 (tasking_setup): Drop into 1-pass mode so that all
7551 tasking-related declarations are installed in the global
7552 scope. Use correct CHILL types for initializers (since
7553 ptr_type_node doesn't have the right meaning for CHILL).
7554 Also, call `do_decl' instead of `decl_temp1' for
7555 `init_struct'.
7556 (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
7557 `chill_finish_compile' in sync between passes.
7559 * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
7560 declarations on pass zero. Keep obstacks in sync, and always
7561 call `finish_decl' for pass zero declarations.
7562 (push_chill_extern_function): Keep obstacks in sync, and always
7563 call `finish_decl' for pass zero declarations.
7564 (build_enumerator): Ditto.
7565 (grok_chill_variantdefs): Change PASS test to exclude only
7566 pass one.
7567 (finish_struct): Ditto.
7568 * ch-expr.c (build_chill_component_ref): Ditto.
7569 (build_chill_binary_op): Ditto.
7570 * ch-tree.c (build_powerset_type): Ditto.
7571 (build_bitstring_type): Ditto.
7572 * ch-typeck.c (build_chill_range_type): Ditto.
7573 (build_chill_struct_type): Ditto.
7575 * ch-decl.c (build_chill_exception_decl): Clarify reasons for
7576 extra pushing and popping of obstacks.
7578 * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
7579 on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
7581 * ch-grant.c (chill_finish_compile): Clear out both
7582 MODULE_INIT_LIST and TASKING_LIST if either contains stuff
7583 from pass one.
7585 * ch-parse.y (rccase_label): Add NAME rules so that pass one
7586 works w/o knowing we're parsing a signal. Simplify SIGNALNAME
7587 rules since we only get SIGNALNAME tokens in pass two.
7588 (sendaction): Ditto.
7589 * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
7590 BUFFERNAME on pass two. The grammar now handles this.
7591 * ch-decl.c (lookup_remembered_decl): Deleted.
7593 Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
7595 * ch-decl.c (lookup_remembered_names): Removed. It was being
7596 misused in ch-lex.l.
7597 * ch-lex.l (name_type_signal): Revert last change. Basically,
7598 we cannot use the C typedef/variable name trick in CHILL, due
7599 due to the language's 2-pass nature.
7600 * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
7601 a seg fault.
7602 * ch-tree.h (lookup_remembered_name): Comment out the prototype.
7604 Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7606 * ch-decl.c (do_decl, push_chill_extern_function): Change pass
7607 checks so the pass == 0 case is handled for built-in types.
7608 (push_modedef): Add check for error_mark_node.
7609 (lookup_remembered_decl): New function.
7610 (pushlevel, poplevel) Change pass checks.
7611 (pushdecl): Check type as well for NULL.
7612 (build_enumerator): Handle pass == 0 case.
7613 * ch-lex.l: Use lookup_remembered_decl to get lastiddecl
7614 during pass 1.
7615 * ch-parse.y: Set pass to zero to indicate initial decl processing.
7616 Replace NAME references with SIGNALNAME references.
7617 (startaction): Only check copy number if not ignoring actions.
7618 Always call build_chill_start_process.
7619 (optstartset): Don't lookup the instance name.
7620 * ch-tasking.c (generate_tasking_code_variable): Replace
7621 do_decl call with decl_temp1 call.
7622 (build_chill_start_action): Check for ignore_actions here.
7623 (build_tasking_message_type): Layout the type.
7624 (rc_state_type): New structure to keep nested receive-case
7625 info in.
7626 (build_chill_receive_case_start, build_chill_receive_case_end):
7627 Use the new struct.
7630 Fri Sep 24 04:19:15 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7632 * ch-tasking.c (build_chill_receive_case_start): `namedecl'
7633 should be a _DECL, not an IDENTIFIER_NODE.
7635 Thu Sep 23 18:18:24 1993 Per Bothner (bothner@kalessin.cygnus.com)
7637 * ch-decl.c (find_implied_types): Handle VAR_DECLs.
7639 * ch-decl.c (print_lang_identifier): Print IDENTIFIER_OUTER_VALUE.
7640 * ch-actions.c (chill_expand_result): Allow value-less RETURN.
7641 * ch-expr.c (resolve_component_ref): Recognize error_mark.
7643 * ch-convert.c (digest_constructor): Handle a nested powerset tuple.
7644 * ch-satisfy.c (satisfy): Use return value of layout_chill_range_type.
7645 * ch-typeck.c (chill_similar): Repeatedly get parent modes
7646 of ranges, not just once.
7647 * ch-typeck.c (chill_root_resulting_mode), ch-tree.h: New function.
7648 * ch-typeck.c (layout_chill_rang_type): Re-do type-checking
7649 to follow Blue Book better (check for Compatibility).
7651 * ch-tree.h (CH_ROOT_RESULTING_MODE): New macro.
7652 * ch-lex.l (use_seizefile_name, current_seizefile_name), ch-tree.h:
7653 New variables. The latter replaces in_seizefile.
7655 Changes to store in the new DECL_SEIZEFILE field each seize
7656 ALIAS_DECL the name in the most recent use_seize_file directive.
7657 (This requires that use_seize_file directives written to the
7658 grant file be written before the SEIZEs that need it.)
7659 Allow clashing declarations granted into the global scope
7660 (produce a warning), but remember the seizefile case from
7661 (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
7662 The a SEIZE will select the granted decl that matches its
7663 DECL_SEIZEFILE (in other words: grants from the most recent
7664 use_seize_file will be preferred).
7665 * ch-tree.h (DECL_SEIZEFILE), ch-tree.def: New macro.
7666 * ch-tree.h (global_value, IDENTIFIER_GLOBAL_VALUE): Renamed
7667 to outer_value, IDENTIFIER_OUTER_VALUE.
7668 Changes to cause the use_seize_file directives to be written
7669 out in order as they're seen in source.
7670 * ch-lex.l (files_to_seize, next_file_to_seize, last_file_to_seize):
7671 Changed to have type TREE_LIST of pointer to IDENTIFIER_NODE.
7672 * ch-lex.l (handle_use_seizefile_directive): Modify appropriately.
7673 Don't call grant_use_seizefile.
7674 * ch-lex.l (mark_use_seizefile_written): New function.
7675 * ch-grant.c (decode_decl): Write out use_seize_file directive,
7676 if needed, before writing a seize declarations.
7677 * ch-decl.c (pop_module): Handle decls granted into the global
7678 module specially, setting IDENTIFIER_OUTER_VALUE.
7679 * ch-decl.c (lookup_name_for_seizing): Check IDENTIFIER_OUTER_VALUE.
7681 Thu Sep 23 19:05:37 1993 Bill Cox (bill@cygnus.com)
7683 * ch-decl.c (push_chill_extern_process): Delete unused variables,
7684 declare the process' tasking_code variable as external.
7685 * ch-parse.y (process): Force ignore_exprs to FALSE while parsing
7686 the process header.
7687 * ch-tasking.c (sigdef): Move resetting of quasi_signal from here
7688 to (signaldef).
7689 * ch-tree.h: Add prototype.
7690 * expr.c (store_constructor): Emergency first-aid. Rewrite later.
7692 Thu Sep 23 12:57:53 1993 Per Bothner (bothner@kalessin.cygnus.com)
7694 * ch-expr.c (build_chill_function_call): Move possible call to
7695 chill_start_module_code until we know we're not calling a builtin.
7696 * ch-decl.c (save_expr_under_name): Use pushdecllist,
7697 not proclaim_decl (which provide for popping the decl).
7698 * ch-parse.y (optname): Also allow TYPENAME.
7700 Thu Sep 23 09:18:35 1993 Bill Cox (bill@cygnus.com)
7702 * ch-decl.c (print_lang_decl): Make weak name output more standard.
7703 (print_lang_identifier): Make signal-data flag output more standard.
7704 (push_chill_extern_process): Pass correct arg tree to
7705 push_chill_extern_function.
7706 (push_syn_decls, fixup_unknown_type, chill_modes_equiv):
7707 Standardize function header layouts (Makes the tcov script
7708 work better).
7709 * ch-except.c (chill_finish_on): Standardize function header.
7710 * ch-expr.c (fold_set_or): Standardize function header.
7711 * ch-grant.c (print_proc_tail, print_proc_exceptions): Standardize

7721 * ch-lex.l (handle_use_seizefile_directive): Don't emit
7722 use_seize_file directive if in_seizefile.
7724 * ch-convert.c (digest_structure_tuple): Fix code that checks
7725 for excess init values.
7726 * ch-decl.c (layout_chill_variants): Move increment of nlabels
7727 inside the proper loop.
7728 * ch-grant.c (print_struct): Add missing loop for tag_list.
7729 (print_struct): Look for variant fields by checking for a
7730 UNION_TYPE, not a NULL name, since we must use a dummy name.
7731 * ch-parse.y (structured_variable): Various fixing.
7732 * ch-decl.c (shadow_record_fields): Rename arg decl -> struct_val.
7734 * ch-satisfy.c (safe_satisfy_decl): Disable copying of modes
7735 for NEWMODE (and hence novelty checking), until we figure out
7736 a better way.
7738 * ch-except.c (finish_handler_array): Use null_pointer_node,
7739 not integer_zero_node (which fails to type-check).
7741 * c-typeck.c (get_constructor_element_type): New function.
7742 * ch-tree.h (CH_NOVELTY_FLAG): Now also used in TYPE_DECLs.
7743 (CH_NOVELTY): Redefined to call new function chill_novelty.
7744 (CH_CLASS_IS_XXX, TYPE_NEWMODE, CH_CLASS_MODE): Removed.
7745 * ch-typeck.c (classify_chill_expr renamed to chill_expr_class):
7746 Take extra output parameter (for M, as in M-value class).
7747 * ch-typeck.c (chill_novelty): New function. (Also de-references.)
7749 * ch-expr.c (resolve_component_ref, build_chill_component_ref):
7750 New functions. Handle 2-pass and variant records.
7751 * ch-parse.y (primval DOT name): Use instead of build_component_ref.
7752 * ch-satisfy.c (satisfy, case COMPONENT_REF):
7753 New case, call resolve_component_ref.
7755 * ch-expr.c (build_generalized_call): Extract single arg from
7756 arg list before calling build_chill_cast.
7758 * ch-parse.y (defining_occurrence_list): New non-terminal.
7759 Use it to replace locnamelist, synnames, and modenames.
7760 * ch-parse.y: Re-write parsing of variant records.
7762 * ch-decl.c (grok_chill_variantdefs): Now return a FIELD_DECL
7763 rather than just its type.
7764 * ch-inout.c (build_chill_io_list_type), ch-parse.y:
7765 Change callers appropriately.
7767 * ch-tree.h (TYPE_TAG_VALUES): Add an extra level of TREE_LIST,

7792 (shadow_record_fields): Rename formal param for readability.
7793 * ch-grant.c (decode_decl): Write proper header for a process.
7794 * ch-parse.y (quasi_pdef): process now uses processparlist,
7795 which doesn't change with the passes.
7796 (quasi_locdec): Call build_chill_reference_type to defer
7797 doing the type's layout.
7798 (processpar): Use paramnamelist, but reformat it into a
7799 list of identifiers in pass 2, so a processpar is the same
7800 structure in both passes.
7801 (locdec): Call build_chill_reference_type to defer doing the
7802 type's layout.
7803 * ch-tasking.c (generate_tasking_code_variable): Call do_decl to
7804 build the decl. Only update the variable's tree in pass 2.
7805 (make_process_struct): Call build_chill_reference_type to defer
7806 doing the type's layout.
7807 (build_process_header): New code to call make_process_struct.
7808 New pass-2 code to make a PARM_DECL for start_chill_function.
7809 Pass a void_type_node, not a NULL_TREE for an empty list.
7810 Get input for shadow_record_fields from current_function_decl.
7811 (build_buffer_decl): Call do_decl not decl_temp1.
7812 * ch-typeck.c: Reindent to standards.
7813 * gcc.c (SPECS): Add recognition for the '.chi' CHILL suffix.
7815 Mon Sep 20 12:00:24 1993 Per Bothner (bothner@kalessin.cygnus.com)
7817 * ch-typeck.c (classify_chill_expr): An expression with a
7818 REFERENCE_TYPE still has VALUE class, even if an ADDR_EXPR.
7819 * ch-actions.c (adjust_parm_or_field):, ch-tree.h: Change last
7820 parameter, so we can reliably recognize LOC parameters.
7821 * ch-tasking.c, ch-expr.c: Change callers appropriately.

7831 to handle conversions and LOC args better.
7832 * ch-actions.c (chill_expand_assignment): Simplify conversions.

7839 * ch-lex.l: Remove some obsolete stuff.
7840 * ch-convert.c (convert): Move conversion from reference to

7844 Fri Sep 10 12:23:41 1993 Wilfried Moser (fs_moser@cygnus.com)
7846 * Makefile.in: Change installation of the chill script. gcc will

7960 pass 2.
7961 * ch-grant.c (print_proc_tail): Avoid trying to format
7962 a VOID return type, or using a NULL pointer.

8719 * ch-lex.l (RETURN_PREDEF): New macro. Uses ridpointers
8720 for all preferedined types.
8721 * ch-lex.l (init_lex): Upper case all RIDs, so grantfiles
8722 (and error messages?) will use uppercase.

8767 * ch-decl.c: See Generally.
8768 (init_decl_processing): Call build_tasking_enum from here.

8865 * ch-decl.c (temp_pushdecl, bind_saved_names): The simple-minded
8866 way I allocated the shadow_list on an obstack was too fragile,
8867 so just use xmalloc/free instead.

9044 header. Use #undef to assure that strchr isn't a
9045 macro (portability), and remove the extra paren-
9046 theses in its extern name.
9047 (check_newline): Call getlc less often, so that user
9048 labels aren't lowercased before their time. Add BEGIN
9049 INITIAL before starting pass 2, so the header is

10279 to end of parameter types list.
10281 * ch-grant.c (chill_start_module_code): Make sure module

10396 * varasm.c (mak_function_rtl): Remove kludge that may
10397 not be necessary (and loses anyway).

10448 * ch-decl.c (massage_param_node): New function.
10449 It handles the LOC/IN/OUT/INOUT parameter distinction,

10477 Mon Apr 5 19:56:56 1993 Bill Cox (bill@rtl.cygnus.com)
10479 * ch-actions.c, ch-decl.c: Use tree_int_cst_equal and integer_zerop

10501 Major re-write of New module/seize/grant stuff.
10502 Now, a grantfile is a spec module and contains all the
10503 top-level declarations of the granting module, not just
10504 those that are granted. It also contains explicit grant
10505 statments naming those declared names that are granted.
10506 It also has seize statements and use_seize_file directives
10507 to correctly handle transitive dependencies.
10509 * ch-parse.y: Change to allow multiple modules per source file.
10510 Allow spec modules (including quasi definitions) as well as
10511 regular modules.
10512 Allow spec modules inside normal modules; these behave as if
10513 they were outermost. This violates the Blue Book, but is
10514 needed by the new grantfile mechanism. (A grant file is a
10515 spec module that gets included by the use_seize_file directive.)
10516 * ch-parse.y (struct module *current_module, push_module,
10517 pop_module): Support module nesting (for spec modules only).
10519 * ch-tree.h (struct module): New.
10520 * ch-grant.c (granted_decls): New list of declarations
10521 that have been granted into the outermode pseudo-module.
10522 * ch-grant.c (decode_mode): If the decl has a name,
10523 always write the name, not just if the decl has already
10524 been written. Since we write out all decls, we can assume
10525 it will be written later, and depend on the forward
10526 declaration kludges to catch it.
10527 * ch-grant.c (decode_decl): Don't write out _EXTERN.
10528 Instead write out standard (Blue Book) quasi-definitions.
10529 * ch-grant.c (push_granted): New function.
10530 * ch-grant.c (seize_implied_names): New function. Re-write
10531 how set element names are seized when a set type is seized.
10532 * ch-grant.c (chill_seize): Work by seraching the
10533 granted_decls list and copying the declaration.
10534 * ch-grant.c (chill_grant): Write all declarations
10535 declared in this module. Write GRANT statements for
10536 those granted. seize statements for decls seized from
10537 other modules. Write extra syntax to make a complete
10538 spec module.
10539 * ch-grant.c (grant_use_seizefile): Copy use_seize_file
10540 directives into grant file.
10541 * ch-lex.l (setup_seizefile_read): Call grant_use_seizefile.
10543 * ch-lex.l (struct input_state, current_input_state,
10544 push_input_file, pop_input_file): New (type, variable,
10545 function*2). Used to save and restore state on an input file.
10546 * ch-lex.l: Clean up to handle nested input seizefiles
10547 (needed by new grant/seize mechanism.
10548 * ch-lex.l (skip_to_end_of_directive): New function.
10549 * ch-lex.l (compiler_directive: USE_SEIZE_FILE): Make sure
10550 we skip to the end of the directive *before* we switch
10551 input files.
10552 * ch-lex.l (setup_seizefile_read): Prevent reading the
10553 same seizefile twice (otherwise likely with new grant/seize).
10554 * ch-lex.l: Recognize SPEC. Misc cleanups.
10556 * ch-parse.y: Fixed foreward references of types.
10557 Removed the unknown_type_node crock.
10558 * ch-decl.c: Remove all uses of unknown_type_node.
10559 Check for TYPE_SIZE zero instead.
10560 * ch-decl.c (fixup_unknown_type): Make sure new mode
10561 gets copied into old mode. Merge their variant chains.
10562 * c-decl.c (lookup_name_current_level): Make non-static.
10563 * ch-decl.c (lookup_name_current_level): No longer needed.
10565 * ch-parse.y (call): Allow an implicitly defined function
10566 name following the CALL keyword.
10567 * ch-tree.h (struct lang_identifier): Add implicit_decl,
10568 and make sure order of fields matches c-tree.h.
10570 * ch-actions.c (lang_init, build_allocate_memory_call,
10571 build_allocate_globals_memory_call): Fix names (add initial '_')
10572 and prototypes of _allocate_[global_]memory (2nd param is ref).
10573 Use build_chill_function_call, not build_function_call,
10574 so the reference parameter gets handled.
10575 * ch-actions.c. (lang_init): Make sure boolean_{true,false}_node
10576 have boolean_type_node as their types.
10577 * ch-actions.c (build_chill_lower, build_chill_upper): Fix to
10578 work for arrays with BOOLEAN_TYPE ranges (and simplify some).
10580 * ch-except.c: Make sure an end_label is generated,
10581 and jump to it if there is no exception.
10583 * ch-convert.c (convert_to_reference): Strip off NOP_EXPR casts.
10584 * expr.c (expand_expr): Handle NOP_EXPR as Chill-style casts.
10585 (Need cleaning up and FSF installation!)
10586 * ch-parse.y: If taking the address of a cast, move the
10587 ADDR_EXPR inside the NOP_EXPR.
10589 * ch-typeck.c (my_build_array_ref): Simplified, more suitable
10590 versions of build_array_ref from c-decl.c. (E.g. don't barf
10591 if index type is char or bool.)
10592 * ch-typeck.c (build_chill_array_ref): Use my_build_array-ref.
10594 * ch-typech.c (build_chill_bin_type): New function.
10595 Support BIN(N) range type specification.
10596 * ch-parse.y (mode2), ch-lex.l: Recognize BIN(N).
10598 * ch-tree.h (CH_SIMILAR): Redefine in terms of chill_similar.
10599 * ch-typeck.c (chill_similar): New function. Recognize that
10600 that range types are similar to their parent types.
10602 * ch-tree.h: Declare flag_local_loop_counter.
10603 * ch-loop.c: Whether the loop variable is local to the loop
10604 in now controlled by flag_local_loop_counter, instead of
10605 #ifdef'd on CREATE_SCOPE.
10606 * ch-actions.c (lang_decode_option): Recognize flags
10607 "-f[no-]local-loop-counter".
10608 * toplev.c (lang_options): Add Chill flags -f[no-]local-loop-counter.
10610 * varasm.c (make_function_rtl): Due to problems with forward
10611 references, don't rename nested functions in Chill. (Kudge!)
10613 Sun Mar 28 10:12:45 1993 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10615 * ch-lex.l (push_back, readstring): Fix prototypes.

10637 as-yet-undeclared types. Check for IDENTIFIER_NODE, lookup its
10638 DECL if there, pass TREE_TYPE of decl to build_pointer_type.
10639 (variantfields, varianthack): Clean up.
10640 (variantfield): Check for IDENTIFIER_NODE, lookup its DECL if
10641 there, pass TREE_TYPE of decl to grok_fixedfields.
10642 (labellist): Explicitly assign error_mark_node to signal error.
10643 * ch-typeck.c (chill_compatible): Report FALSE for bad parameters,
10644 rather than seg faulting.
10646 Thu Mar 25 10:35:58 1993 Bill Cox (bill@rtl.cygnus.com)
10648 * ch-actions.c (lang_init): build_function_type for allocate_memory

10668 chill_expand_array_assignment can do a better job of
10669 code-generation.
10670 * ch-expr.c (chill_expand_array_assignment): Generate the CONCAT_EXPR
10671 code.

10676 array and its type get on the permanent obstack.
10677 * ch-grant.c (write_grant_file): Don't write the _INIT=name
10678 specifier: It isn't needed, and loses (because of funny

10681 * ch-lang.c (finish_chill_enum): Don't allocate a dummy
10682 TYPE_DECL for the enum. I don't think it is needed (?),

10699 after each statement. Move convert call into
10700 chill_expand_assignment from ch-parse.y.
10701 * ch-grant.c: Generally re-order, clean up. Include Per's decode_mode
10702 simplification. Include commented-out hack in decode_mode to return

10721 vents seg fault when only WITH operand is invalid.
10722 * ch-parse.y (label_spec): Correct assignment within IF expression which
10723 was intended to be equality test. Remove unused variables.
10724 * ch-tree.h: Add prototype. Remove unused EXCP_CODE enumeration, and
10725 prototyping editorial comments.
10726 * ch-typeck.c: Disable generation of code to validate array index for
10727 now. Should be done as a call-back from more generic array_ref code.

10863 convention.
10864 build_set_expr: Remove length parameter, call powersetlen() instead.
10865 remove handling of CHAR arrays - they're handled in build_char_array_expr.
10866 Call __eqpowerset to test for equality - we can't use a byte-length -
10867 need bitcount instead.
10868 build_chill_compound_expr, internal_build_compound_expr: Copy from C
10869 version that does stuff we don't want.
10870 build_binary_op: Check for in_size_in_bytes return < 0, indicating

10874 build_chill_card: Call powersetlen.
10875 build_chill_max_min: Common code for powerset max/min.
10876 build_chill_length: Move VARYING array handling before regular char
10877 array handling.
10878 * ch-expr.c chill_expand_expr: Disable concatenate code - we need to
10879 the VARYING status of the target to do this correctly. Use powersetlen
10880 for the powerset operations, not a byte length.
10881 * ch-loop.c: Make CREATE_SCOPE #define to enable creation of a new scope
10882 for each CHILL loop, as Z.200 requires. Add powerset and error flags
10883 to loop structure. Evaluate user's powerset expression into a temp,
10884 scan it destructively with __ffsetclrpowerset or __flsetclrpowerset
10885 for powerset loop. Only do loop-end assignments if NOT a powerset
10886 loop, which has much less overhead now.
10887 * ch-tree.h: Add prototype for powersetlen.

10940 * ch-typeck.c (build_chill_array_ref): Convert INDEX to
10941 TYPE_MIN_VALUE of DOMAIN if the types are compatible.
10943 * ch-grant.c (chill_seize): If DECLS is a TYPE_DECL for an
10944 ARRAY_TYPE, seize the domain type if its a set.

11005 * ch-convert.c (convert): Slightly more correct conversion
11006 for ARRAY_TYPEs (return as OK if CH_COMPATIBLE).
11007 * ch-expr.c (chill_expand_array_assignment): Invoke

11059 special-case support for a BIT_FIELD_REF in right-hand-side.
11060 * ch-lang.c (finish_chill_enum): Patch up enum elements to
11061 have the correct type (instead of integers, as in C).
11063 * ch-lex.l, ch-parse.y: Add disgusting hack (involving

11104 * ch-lex.l (convert_bitstring), Changed SET_TYPE_CONSTRUCTOR to
11105 take a list of elements which are in the set. This corresponds

11108 New functions, to expand SET_TYPE CONSTRUCTORs.
11109 * varasm.c (output_constructor): Use pack_set_constructor
11110 to assemble a SET_TYPE constant from a CONSTRUCTOR.
11112 * ch-grant.c (decode_constant): Better grant for strings,
11113 enumeral, and bitstring constants.
11114 * ch-grant.c: Fixes in seize to avoid duplicates, and emit
11115 things in the correct order.
11116 * c-typeck.c (chill_initializer_constant_valid_p): Kludge
11117 needed to export a static function.
11118 * ch-typeck.c (convert): Avoid needlessly (and lossingly) calling
11119 chill_expand_tuple to convert fix string to varying.
11120 * ch-actions.c (build_chill_binary_op): Promote short
11121 integer operands if needed (otherwise emit routines barf).
11122 * ch-tree.h (SET_WORD_SIZE): New macro.
11123 * ch-parse.y: Fix syntax for RECEIVE CASE.
11124 * ch-parse.y (location): If IDENTIFIER is a CONST_DECL

11142 redefine the signatures for those runtime routines. Move
11143 empty-set check into runtime.
11144 * ch-expr.c, ch-loop.c, ch-process.c, ch-tree.c, ch-typeck.c: change
11145 most integer_type_node references to chill_integer_type_node.

11149 * ch-except.c: New file. Stuff for exception handling.
11150 * ch-parse.y: Add working exception handling support.
11151 * ch-lex.l, ch-parse.y: Prefer standard type terminology
11152 (BOOLS, CHARS) even though non-standard (BITS, CHAR) is ok.
11153 * ch-grant.c: Fix various problems related to granting
11154 types such as bitsets.
11155 * ch-tree.c (build_bitstring_type): Set TYPE_MIN_VALUE
11156 to distinguish bitstrings from powersets (in the same way
11157 we distinguish char strings from char arrays).

11159 * ch-tree.h, ch-actions.c (lang_init), ch-grant.c (decode_mode):
11160 Undo kludge where integer_type_node was hardwired to 16 bits.
11161 Make integer_type_node etc have the same size as in cc1.
11162 New types chill_integer_type_node and chill_unsigned_type_node
11163 that correspond to the Chill source types INT and UINT.
11164 For now, these match the C 'short' types, but that should
11165 become a configuration option later,

11169 * ch-actions.c (build_chill_unary_op): allow NOT of a set.

11180 * ch-tree.h: remove prototypes added to c-tree.h.
11181 * ch-typeck.c (build_chill_array_ref): correct getting domain
11182 subtree for a PARM_DECL. Subscripting a SET_TYPE is turned into

11185 Sun Feb 7 18:20:49 1993 Bill Cox (bill@rtl.cygnus.com)
11187 * ch-tree.def: add a new tree type - just for varying array
11188 references. We were using ARRAY_REF, but the underlying C
11189 code also generates that one.
11190 * ch-convert.c, ch-expr.c, ch-typeck.c: use the new tree type.
11192 Sun Feb 7 17:33:17 1993 Bill Cox (bill@rtl.cygnus.com)

11200 * cccp.c: Merge in various Chill-specific changes.
11201 * gcc.c (default_compilers array): Pass -lang-chill

11206 * Makefile.in (install-libchill, install-librmt): Removed.
11207 * ch-actions.c (build_chill_exception_decl): Change decl

11221 and only if multiple indexes.

11231 * ch-typeck.c (chill_expand_tuple): handle set initializations better.
11233 Thu Jan 28 17:41:58 1993 Per Bothner (bothner@rtl.cygnus.com)
11235 * ch-grant.c (set_default_grant_file): Change default.
11236 Normally, grant file should end up in cwd.
11237 * ch-lang.c (build_chill_struct_type): Call pushtag,
11238 for the sake of debugging.
11239 * ch-lex.l: Improve comment parsing.

11254 supervision actions & builtins
11255 * ch-parse.y (call): eliminate optlocarrayidx, call build_chill_slice,
11256 smaller actions directly (maybe_array_ref() used to call them).
11257 * ch-tree.h: add build_chill_function_call, build_chill_slice
11258 * ch-typeck.c: add build_chill_slice()

11282 we assume check_end_label has already been called.
11283 * ch-parse.y: Put in infrastructure for exception handling.
11285 Wed Jan 27 15:45:20 1993 Bill Cox (bill@rtl.cygnus.com)
11287 * ch-actions.c: delete convert_chill_parameter, replace call with
11288 call to convert().
11289 * ch-convert.c (convert): combine chill_give_type_to_expr in here.
11290 * ch-decl.c: call convert rather than chill_give_type_to_expr.
11291 * ch-expr.c: delete chill_expand_array_assignment, move code to convert.
11292 * ch-expr.c (chill_expand_assignment): just call convert.

11370 call to check_identifier. Use where appropriate.
11371 * ch-parse.y (operand5): Only allow string repetition of

11420 chill front end to distinquish between true string types and
11421 arrays of char, since it uses ARRAY_TYPE for both, rather than
11422 trying to use the existing support for STRING_TYPE.

11484 * chill.gperf, ch-hash.h: add Wilfried's tokens
11485 * ch-lex.l: fold in Wilfried's changes. Some tokens

11500 * expmed.c (store_bit_field, extract_field_field): Undo
11501 yesterday's removal of MEM_IN_STRUCT_P "sanity test".
11503 * ch-decl.c (do_decls): Put back support for initializing.

11516 Use build_bitstring_type, not build_string_type.
11517 * expmed.c (store_bit_field, extract_field_field): Remove
11518 "sanity test" that prevents use with SET_TYPE.
11519 * tree.c (build_bitstring_type, build_powerset_type,

11598 * ch-grant.c, ch-parse.y: Remove all code for explicitly
11599 calling initializer functions. This is not needed, since we
11600 use the same mechanism used for C++ static constructors.
11601 * ch-grant.c (chill_start_module_code): Make sure the
11602 init_name starts with the magic string also used for C++
11603 initializers. Also, don't embed the file name in the name,
11604 just use the module name.
11605 * ch-grant.c (chill_finish_module_code): Now that the
11606 initializer name follows the standard 'collect' convention,
11607 don't need to call assembler_constructor_alias, but can

11610 needed function.
11611 * ch-parse.y: Move code that is common to the beginning of

11652 Sat Jan 2 15:04:13 1993 Bill Cox (bill@cygnus.com)
11654 * ch-hash.h, chill.gperf: cleanup. fewer keywords seen by ch-parse.y.
11656 Sat Jan 2 13:27:49 1993 Per Bothner (bothner@rtl.cygnus.com)
11658 * ch-lex.l (check_newline): Use the orginal versions (derived
11659 from the C code, not the simplified, special-case version).
11660 Also, fix that version of check_newline to not call yylex()
11661 recursively.
11662 * ch-lex.l (yy_input): Call check_newline to handle
11663 newlines and check for # directives.
11664 * ch-lex.l (syntax): Don't recognize #-directives; these
11665 are now handled by check_newline.
11666 * ch-actions.c (lang_init): Call the modified version of
11667 check_newline(). Do this at the *after* we've initialized
11668 standard types, so this can be done while lineno is still 0.

11682 C++ defines it.
11683 * ch-grant.c (chill_start_module_code): Use JOINER character
11684 to implement name mangling for the initializer function name.
11685 Algorithm is designed to be simple, distinct from C++ mangled
11686 symbols, and easy to convert to demangled form.

11704 * ch-convert.c (convert_to_reference, convert_from_reference):
11705 New routines, to handle loc-identity declared variables and
11706 LOC parameters (both of which are implemented as references).
11707 * ch-lang.c (convert_to_boolean, convert_to_char): Move to
11708 ch-convert.c, where they would seem to belong.
11709 * ch-convert.c (convert): New function, since we no longer
11710 link in c-convert.c.
11711 * ch-expr.c (chill_expand_assignment): Handle by calling
11712 convert() instead of chill_comptypes().
11713 Also handle the LHS being a reference.
11714 * ch-parse.y: Add a procedure call as an action.
11715 * ch-parse.y (locdec, optlocinit): Move handling of
11716 loc-identity declarations from optlocinit to locdec
11717 - and add working semantics for it.
11718 * ch-parse.y (seizestatement, visibilty_stmt): Simplify.
11719 * ch-parse.y (grantstatement etc): Don't bother making list.
11720 * ch-lex.l: #include <sys/types.h> before <sys/stat.h>.

11726 * ch-typeck.c: allow VARYING structures in assign_type_to_expr.
11728 Tue Dec 29 15:28:48 1992 Bill Cox (bill@cygnus.com)
11730 * ch-actions.c: implement expressions of arrays of char,
11731 ( concatenation, relationals ), correct type of code parameters
11732 * ch-expr.c: correct type of code parameters
11734 Tue Dec 29 11:16:19 1992 Bill Cox (bill@cygnus.com)
11736 * ch-decl.c: cleanup.
11737 * ch-parse.y: put emit_line_note() calls in lotsa places,
11738 per Fred's request; be sure that statements get counted also.
11739 * ch-lex.l: standardize function headers.
11741 Tue Dec 29 10:41:56 1992 Fred Fish (fnf@cygnus.com)
11743 * ch-decl.c (start_chill_function): Always return 1, rather
11744 than a random value.
11745 * ch-lex.l (check_newline): Add a version for chill that
11746 just snarfs the right value for main_input_filename out of
11747 the first line of the input file, without disturbing the
11748 lexer state or requiring it's assistance.
11749 * ch-actions.c (lang_init): Call check_newline, like the
11750 other language frontends, to get main_input_filename set
11751 from first line of input file.
11753 Mon Dec 28 18:49:01 1992 Bill Cox (bill@cygnus.com)
11755 * ch-parse.y: clean up conflicts. The remaining one is
11756 harmless.
11758 Mon Dec 28 17:28:40 1992 Bill Cox (bill@cygnus.com)
11760 * ch-parse.y, ch-lex.l, ch-actions.c: add stubs for I/O,

11766 CHILL I/O
11768 Sat Dec 26 20:48:23 1992 Fred Fish (fnf@cygnus.com)
11770 * chillrt/chillrt0.c: Oops, SVR4 doesn't need leading '_'
11771 on build_exceptions.
11773 Sat Dec 26 11:00:36 1992 Fred Fish (fnf@cygnus.com)
11775 * ch-grant.c (chill_finish_module_code): Call
11776 assemble_constructor_alias rather than assemble_constructor.
11777 * varasm.c (assemble_constructor_alias): New function,
11778 like assemble_constructor, but also handles the case where
11779 ASM_OUTPUT_CONSTRUCTOR is not defined and GNU ld is not
11780 being used. Emits a symbol table alias name with the correct
11781 prefix for collect to find and add to the __CTOR_LIST__.
11782 * chillrt/chillrt0.c: Build on previous hack that gets
11783 _build_exceptions into the __CTOR_LIST__, to make it work
11784 for both the non GNU-ld case and for the SVR4 case.
11786 Tue Dec 22 18:24:55 1992 Bill Cox (bill@cygnus.com)
11788 * ch-loop.c: clean up location enumeration - one more
11789 pass to do.
11791 Tue Dec 22 16:31:48 1992 Bill Cox (bill@cygnus.com)

11801 * ch-parse.y, c-decl.c: Add Jukka's Pascal WITH code.
11802 ch-loop.c: rough draft of location enumeration
11803 ch-lex.l, ch-expr.c, ch-decl.c: minor cleanup
11804 ch-actions.c: finish making pred() and succ() work.
11806 Mon Dec 21 10:04:35 1992 Bill Cox (bill@cygnus.com)
11808 * ch-actions.c: allow pred(char) and succ(char).
11810 Sun Dec 20 16:04:28 1992 Bill Cox (bill@cygnus.com)
11812 * ch-expr.c, ch-actions.c, ch-parse.y, ch-loop.c,
11813 c-expr.c: make DO WITH work.
11815 Sun Dec 20 12:22:53 1992 Bill Cox (bill@cygnus.com)
11817 * ch-loop.c, ch-actions.c, ch-typeck.c: powerset loops
11818 now work
11820 Sat Dec 19 14:20:23 1992 Per Bothner (bothner@cygnus.com)
11822 * c-typeck.c (process_init_constructor): Add warning if
11823 there is a duplicate default initializer element.
11824 * ch-typeck.c (chill_give_type_to_expr): New function,
11825 to handle coercion of an expression to context-given type,
11826 Takes care of untyped tuples, and case expressions.
11827 * ch-decl.c (do_decls), ch-typeck.c (chill_expand_return,
11828 chill_expand_result), ch-parse.y <assignaction>:
11829 Use chill_give_type_to_expr().
11830 * ch-typeck.c (chill_handle_case_label): New parameter list,
11831 to handle the (new) conventions for <case_label>, including
11832 default elements and ranges.
11833 * ch-parse.y <expanded_case_label>, ch-typeck.c
11834 (expand_case_expr): Use new version of chill_handle_case_label.
11835 * ch-decl.c (push_syndecls): Change parameters: Instead of
11836 TREE_LIST representing a compete <synonym definition statement>,
11837 just pass the parts of a single <synonym definition> as 3
11838 different parameters. Also, use chill_give_type_to_expr(),
11839 to handle untyped tuples in the RHS.
11840 * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct
11841 a tree - just call push_syndecls() on each <synonum_definition>
11842 as we see it.
11843 * ch-parse.y (exprlist_get_single): Remove; no longer needed.
11844 * ch-parse.y: Handle <tuple> without mode name diferently from
11845 <tuple> with mode name. The latter is a <primval> that can be
11846 in most contexts, but if the <mode name> is missing, the <tuple>
11847 is only allowed in certain contexts. Use the new non-terminal
11848 <untyped_expr> to indicate those contexts where untyped tuples
11849 (and case expressions) are valid because the expression gets a
11850 type from its context (such as the RHS of an assignment).
11851 Use chill_give_type_to_expr in those contexts.
11853 Sat Dec 19 14:01:26 1992 Bill Cox (bill@cygnus.com)
11855 * ch-actions.c, ch-loop.c, Makefile.in: looping stuff.
11857 Sat Dec 19 10:16:20 1992 Bill Cox (bill@cygnus.com)
11859 * ch-parse.y: clean up warning messages from byacc. bison
11860 still complains thrice.
11862 Fri Dec 18 12:33:29 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11864 * ch-actions.c (maybe_chill_comptypes): Delete unused
11865 function.
11866 (chill_comptypes): Add new parameter ERRSTR. All callers
11867 changed.
11868 (build_chill_binary_op): Fix indentation to match GNU coding
11869 style.
11871 Fri Dec 18 08:18:13 1992 Bill Cox (bill@rtl.cygnus.com)
11873 * ch-parse.y, ch-expr.c, ch-actions.c, expr.c: major

11883 a default initializer element.
11884 * ch-parse.y: Implement default elements for tuples
11885 (as in '(else):' and '(*):' ).
11887 * ch-parse.y: Previous change to dis-ambiguate case-labels
11888 seems to have allowed getting rid of all of the expr_or_list hair.
11889 * ch-decl.c (do_decls): Undo Tiemann's change to "Handle
11890 initialization of multiple variables by a tuple" - the
11891 idea is bogus.
11893 Wed Dec 16 11:17:53 1992 Bill Cox (bill@cygnus.com)
11895 * ch-parse.y: complete re-write of DO statement handling.
11896 now operational, except WITH is stubbed out. Improved
11897 syntax error message.
11898 * ch-actions.c: DO support: high_domain_value(), low_domain_value ().
11899 * ch-expr.c: fixes to IN_EXPR handling.
11901 Tue Dec 15 17:15:13 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11903 * ch-grant.c: Add casts to alloca return to avoid compiler warning.
11904 * ch-lex.c: Likewise.
11906 * Makefile.in (ch-lex.c): Delete incorrect free declaration added
11907 by flex to avoid compiler error.

11911 * ch-decl.c (do_decls): Handle initialization of multiple
11912 variables by a tuple.
11914 * ch-decl.c (do_decls,start_chill_function): Make DECL public
11915 if we're doing a GRANT ALL at top level.
11917 * ch-lang.c (build_range_type): Deal with typecast to CHAR in
11918 range expression.
11920 * c-typeck.c (digest_init): SET_TYPE is not a scalar type.
11921 BOOLEAN_TYPE and CHAR_TYPE are scalar types.
11923 Mon Dec 14 14:58:32 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11925 * ch-lex.l (get_chill_{linenumber,filename}): New functions.
11926 (convert_number): Use LONG_TYPE_NODE instead of INTEGER_TYPE_NODE.
11928 Mon Dec 14 13:36:44 1992 Bill Cox (bill@cygnus.com)
11930 * expr.c: install and test newer Pascal IN_EXPR code,
11931 but don't activate it - it's very verbose.
11933 Mon Dec 14 00:22:49 1992 Fred Fish (fnf@cygnus.com)
11935 * Makefile.in (LANGUAGES): Add chill.

11951 Sun Dec 13 14:07:32 1992 Bill Cox (bill@cygnus.com)
11953 * ch-actions.c: fix unary operations, modulus ops,
11954 (discovered after extending regression tests).
11956 Sun Dec 13 12:16:32 1992 Bill Cox (bill@cygnus.com)
11958 * resync with Michael and Wilfried
11960 Sun Dec 13 09:11:25 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11962 * ch-parse.y (output_constant): Fixed some whitespace
11963 problems.
11964 * ch-tree.h: Add declarations for new chill functions that
11965 have been implemented but not (yet) declared.
11967 Sat Dec 12 00:17:23 1992 Per Bothner (bothner@cygnus.com)
11969 * c-typeck.c (process_init_constructor): Warn about duplicate
11970 labels for labelled initializer elements.
11971 * ch-lex.l (various operator tokens, such as "+"): Don't
11972 set yylval.code to a TREE_CODE; this is better done in parser.
11973 * ch-parse.y: Some work with case labels and tuples.
11974 Get literal range as tuple (and case) labels working.
11975 Fix some problems introduced by recent grammar overhaul.
11977 Fri Dec 11 13:28:48 1992 Bill Cox (bill@cygnus.com)
11979 * ch-actions.c, ch-parse.y ch-tree.h ch-expr.c, ch-typeck.c:
11980 got long, real expressions working. We can also call a func-
11981 tion and use its return value.
11983 Thu Dec 10 14:45:17 1992 Per Bothner (bothner@cygnus.com)
11985 * ch-parse.y: Major change to remove or at least identify
11986 parser ambiguities. One result: We now allow actions that
11987 start with '(', as required by teh Blue Book. This does break
11988 some things; look for FIXME for things that need work.
11989 * ch-typeck.c (chill_expand_case_expr): We need an extra
11990 level of looping to (in the future) support <case label
11991 specification>s with more than one <case label list>.
11993 Thu Dec 10 09:21:41 1992 Bill Cox (bill@cygnus.com)
11995 * ch-actions.c, ch-expr.c: Implement string assignments
11996 and relationals.
11998 Thu Dec 10 07:17:35 1992 Bill Cox (bill@cygnus.com)
12000 * ch-decl.c, ch-typeck.c: rest of previous commit.
12002 Wed Dec 9 18:26:29 1992 Bill Cox (bill@cygnus.com)
12004 * ch-parse.y, ch-actions.c, ch-expr.c: redo type checking.
12005 regression test and fix bit arrays and set ops.
12007 Mon Dec 7 14:57:46 1992 Bill Cox (bill@cygnus.com)
12009 * ch-actions.c: implement crude relationals between
12010 non-exotic operands, such as integers.
12012 Mon Dec 7 10:42:35 1992 Bill Cox (bill@cygnus.com)
12014 * ch-actions.c: implement relational, logic operations
12015 on arrays of BOOLs.
12017 Mon Dec 7 08:55:20 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
12019 * ch-actions.c (lang_init): Set LINENO to 1 at beginning to
12020 indicate we are done with initialization.
12022 * ch-decl.c (do_decls): Set TREE_PUBLIC if we are doing a
12023 `grant all'.
12024 (start_chill_function): Ditto.
12026 * ch-lex.c (convert_bitstring): Set TREE_CONSTANT.
12027 (compiler_directive): Don't confuse compiler directives with
12028 equality comparison operators.
12030 * ch-parse.y: Clear CURRENT_LOCNAMELIST after calling do_decls.
12032 Sun Dec 6 13:12:32 1992 Bill Cox (bill@cygnus.com)

12041 Fri Dec 4 13:54:58 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
12043 * tree.def: Move CARD_EXPR and SET_LE_EXPR back down with the other
12044 Pascal-required ones, since C++ no longer needs them. When
12045 Chill's public, a comment can be added to the effect that
12046 SET_LE_EXPR is also used by Chill.
12048 Fri Dec 4 12:05:01 1992 Bill Cox (bill@cygnus.com)
12050 * Restore CARD_EXPR and SET_LE_EXPR to tree.def.

12060 for type "byte" and FT_unsigned_char for type "ubyte".
12062 Thu Dec 3 15:13:24 1992 Bill Cox (bill@cygnus.com)
12063 * ch-actions.c, ch-tree.def, ch-parse.y: preparation
12064 for powerset expressions.
12066 Tue Dec 2 17:02:30 1992 Bill Cox (bill@cygnus.com)

12089 (push_newmode,push_synmode): Call `fixup_unknown_type' when we
12090 see a declaration that uses `unknown_type_node'. FIXME.
12092 * ch-grant.c (decode_constant): New function.
12093 (decode_decl): Call `decode_constant' for CONST_DECLs.
12095 * ch-lex.l (char action): Use ridpointers instead of
12096 lookup_name to get "char"'s declaration.
12098 * ch-parse.y: Call `build_lang_decl' instead of `build_decl'
12099 when we need to build a TYPE_DECL.
12101 Tue Dec 2 09:44:05 1992 Bill Cox (bill@cygnus.com)
12103 * ch-typeck.c: clean up a gcc warning with a forward
12104 declaration of build_string_type.
12106 Tue Dec 1 16:51:05 1992 Bill Cox (bill@cygnus.com)
12108 * ch-actions.c: completely remove those builtin calls
12109 that are duplicated in c-decl.c
12111 Tue Dec 1 16:38:51 1992 Fred Fish (fnf@cygnus.com)
12113 * ch-actions.c (lang_init): Ifdef out initializations for
12114 __builtin_abs and __builtin_fabs, since they are duplicates of
12115 initializations in c-decl.c, and trigger spurious warnings.
12117 Tue Dec 1 16:35:18 1992 Bill Cox (bill@cygnus.com)
12119 * ch-parse.y: make size() work with a typename argument.
12121 Tue Dec 1 16:15:56 1992 Bill Cox (bill@cygnus.com)
12123 * ch-parse.y, ch-lex.l, ch-actions.c: add builtin
12124 functions min, max, card.
12126 Tue Dec 1 12:35:56 1992 Bill Cox (bill@cygnus.com)
12128 * ch-lex.l: fix char-type
12130 Tue Dec 1 11:10:56 1992 Bill Cox (bill@cygnus.com)

12146 Mon Nov 30 17:35:33 1992 Fred Fish (fnf@cygnus.com)
12148 * chillsh: New script frontend (ala g++), installed as "chill".
12149 Can't be called "chill.sh" because make tries to cat it into the
12150 "chill" directory. Can't be called just "chill" cause that's
12151 already there as a directory.
12152 * Makefile.in: Add rules to install chillsh as "chill".
12153 * chill/libchill.c: Temporarily ifdef out stuff that wants
12154 to conflict with i486/SVR4 runtime or wants to pull in librmt.a,
12155 which itself causes linkage to fail.
12157 Mon Nov 30 16:28:19 1992 Bill Cox (bill@cygnus.com)
12159 * ch-lex.l: added keywords for TRUNC, ROUND, FLOAT, LFLOAT
12160 conversion routines.
12161 * ch-parse.y: added %tokens for TRUNC, ROUND, FLOAT, LFLOAT.
12162 Added production for SIZE(expr).
12163 * ch-actions.c: Add semantic routine chill_sizeof ().

12167 * ch-lex.l, ch-parse.y: Translate token PFEIL into English ARROW.
12168 * ch-parse.y (op6): Remove handling of string repetition operator,
12169 until we can figure out a way to parse it correctly.

12173 dereferencing operator ->.
12175 Mon Nov 30 08:01:29 1992 Bill Cox (bill@cygnus.com)
12177 * ch-actions.c: removed compile warning, better code for abs.
12179 * ch-parse.y: add productions for builtin functions succ, pred,
12180 abs, and size. Add %tokens also. Sort %tokens alphabetically.
12182 * ch-lex.l: add parsing for builtin function names, such as abs,
12183 pred, succ, etc. Put flex -a option into Makefile.in, so we can
12184 clean up the lexer soon.
12186 Tue Nov 24 14:18:48 1992 Per Bothner (bothner@rtl.cygnus.com)
12188 * ch-typeck.c (chill_handle_case_label, chill_handle_case_default):
12189 New functions, for code common to CASE actions and expressions.
12190 * chill.y: Replace some code by calls to chill_handle_case_label
12191 and chill_handle_case_default.
12192 * ch-typeck.c (chill_expand_case_expr): Add semantics.
12194 * tree.c: Change doing_chill_thang from extern to common.
12196 Mon Nov 23 18:34:22 1992 Per Bothner (bothner@rtl.cygnus.com)
12198 * ch-tree.def: New CASE_EXPR type, for case expressions.
12199 * ch-expr.c (chill_expand_expr): Hook for CASE_EXPR.
12200 * ch-typeck.c (chill_expand_case_expr): New function.
12201 Placeholder to implement case expressions.
12202 * ch-typeck.c (chill_expand_result, chill_expand_return):
12203 Handle mode-unspecified tuples and case expressions in
12204 the context of RETURN and RESULT actions.
12205 * chill.y (assignaction): Handle case expressions in the
12206 context of the RHS of an assignment action.
12207 * chill.y (caseaction): Remove spurious duplicate OF in grammar.
12208 * chill.y: Handle labeled structure tuples.
12209 * chill.y: New rules to parse CASE expressions.
12210 * tree.c (build_function_types): Allow Chill functions
12211 to return arrays and functions.
12213 Wed Nov 18 13:50:28 1992 Per Bothner (bothner@rtl.cygnus.com)
12215 * ch-typeck.c (chill_expand_tuple): New function. Expand a
12216 tuple (constructor) given an expected (context) type.
12217 * chill.y: Implement 'LHS := TUPLE' using expand_chill_tuple,
12218 using the mode of the LHS and the expected type of the TUPLE.
12219 * chill.y: Implement initialization.
12220 * chill.y: Fix some syntax bugs (forbidlist must be surrounded
12221 by parentheses), and remove or note ambiguities.
12222 * chill.y: Started converting layout style to be like c-parse.in.
12223 * chill.y: Implement IF expressions.
12224 * chill.y: Added syntax rules for tuples. Labelled and unlabelled
12225 array tuples should now work (in some contexts).
12226 * ch-actions.c: Initialize doing_chill_thang to 1.
12227 * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
12228 initializer, to make pushdecl and finish_decl work.
12229 * c-decl.c (convert_for_assignment): If Chill, don't convert
12230 function and arrays into pointers. (Maybe functions should
12231 still be converted?)
12232 * c-typeck.c (grokdeclarator): Allow functions in Chill
12233 to return arrays and functions.
12235 Mon Nov 16 15:40:47 1992 Per Bothner (bothner@rtl.cygnus.com)
12237 * chill.y (exprlist_get_single): New function, used when
12238 parsing tuples.
12239 * chill.y: Re-did parsing of tuples to remove ambiguities.
12240 This was a bitch.
12242 Tue Nov 10 16:30:55 1992 Per Bothner (bothner@rtl.cygnus.com)
12244 * ch-typeck.c (chill_expand_result); Set TREE_SIDE_EFEFCTS
12245 flags on assignment to result.
12246 * ch-typeck.c (build_chill_array_ref): Subtract lower
12247 bound of domain if non-zero. Preliminary hook for range checking.
12248 * ch-tree.h, chill.l: Combine variables range_check and
12249 range_check_disabled into global variable range_checking.
12250 * ch-tree.h: Better definitions of CH_CLASS_IS_VALUE
12251 CH_CLASS_IS_DERIVED.
