3348 * actions.c (push_action): Take new parameter.
3349 * except.c (push_handler): Likewise.
3350 * parse.c: Change calls to push_action and push_handler.
3351 * loop.c (begin_loop_scope): Always call expand_start_bindings.
3352 * loop.c (end_loop_scope): Always call expand_end_bindings.
3353 * except.c (emit_setup_handler): Add a cleanup to
3354 unlink from exception stack if we return/exit/goto from here.
3355 * loop.c (begin_loop_scope): Move pushlevel from here ...
3356 * parse.c (parse_do_action): ... to here.
3358 Clean up do-decl interface (for decl_temp1).
3359 * parse.c (parse_loc_declaration): If global_bindings_p (),
3360 treat as static.
3361 * decl.c (do_decl): Don't test global_bindings_p ().
3363 * decl.c (keep_next_level_flag, keep_next_if_subblocks):
3364 Not used. Removed.
3365 (struct scope::keep, scope::keep_if_subblocks): Likewise.
3366 (keep_next_level): Likewise.
3367 (kept_level_p, pushlevel, poplevel): Simplify.
3369 * decl.c (init_decl_processing): Don't call init_iterators.
3370 * Makefile.in (C_OBJS): Don't get ../c-iterator.o - not needed.
3372 Thu Sep 15 05:54:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3374 * lex.l (readstring): Add processing of control sequence
3375 in character string literals. The granting mechanism writes
3376 this to grant files.
3378 Tue Sep 13 06:19:42 1994 Wilfried Moser (moser@rtl.cygnus.com)
3380 * expr.c (compare_records): In case of -fpack do always
3381 a memcmp instead of comparing each field of the
3382 structure. If the structure is a variant structure,
3383 issue a warning.
3385 Mon Sep 12 13:15:09 1994 Per Bothner (bothner@cygnus.com)
3387 * grant.c (write_spec_module): Add cast, to avoid PCC warning.
3388 * grant.c (header_template): Don't use ANSI-specific string
3389 literal concatenation.

3393 * tasking.c (get_process_wrapper_name): New function.
3394 (add_taskstuff_to_list): Add a new argument, which is
3395 the entrypoint of a process.
3396 (build_process_header): Change PROCESS arguments to be
3397 like arguments of a function. There will be a wrapper
3398 which is the real entry point for a PROCESS. This wrapper
3399 is automatically build after a PROCESS definition and gets
3400 as argument a pointer to a structure looking like the
3401 arguments of the PROCESS. This wrapper will call the
3402 PROCESS (see build_process_wrapper).
3403 (build_process_wrapper): New function (see above).
3404 (build_start_process): Change processing of arguments.
3405 (tasking_setup): Add processing of a different entry point
3406 in case of PROCESSes.
3408 * parse.c (parse_process_definition): Add call to
3409 build_process_wrapper.
3410 * parse.c (end_function): Remove the poplevel() call.
3411 build_process_header no longer makes the corresponding
3412 pushlevel().
3414 * grant.c (print_proc_tail): Remove special processing
3415 of PROCESSes, they look now like normal functions.
3417 * decl.c (init_decl_processing): Add declaration of memcmp
3418 function.
3420 * ch-tree.h: Add new prototype for build_process_wrapper,
3421 change prototypes for add_taskstuff_to_list and
3422 build_process_header.
3424 * grant.c (write_spec_module): Write GNUCHILL and gcc
3425 version into grant file.
3427 * Make-lang.in (CHILL_FLAGS_TO_PASS): Add passing of CC and
3428 GNUCHILL_VERSION to ch/Makefile.
3429 * Make-lang.in (CHILL.mostlyclean): Add ch/ch-version.c.
3431 * Makefile.in (CHILL_OBJS): Add ch-version.o. ch-version.c
3432 will get generated every time a new Makefile will get
3433 generated.
3434 * Makefile.in (GNUCHILL_VERSION): Remove it, its defined in
3435 Make-lang.in.
3437 * chill.in: In case of -fgrant-only pass "-S -o /dev/null"
3438 to the compiler to avoid generation of an object file.
3440 Thu Sep 8 12:07:28 1994 Per Bothner (bothner@kalessin.cygnus.com)
3442 * convert.c (display_int_cst), ch-tree.h: New function.
3443 * convert.c (digest_array_tuple): Use digest_int_cst to
3444 provide better error messages. Return error_mark_node on error.
3445 * grant.c (decode_const): Simplify by using digest_int_cst.
3446 * grant.c (format_character, find_assoc): Removed.
3448 * decl.c (do_decl): Add missing TREE_CHAIN.
3450 * decl.c (finish_incomplete_decl): Removed.
3451 (init_decl_processing): Don't set incomplete_decl_finalize_hook.
3452 (finish_decl): Remove old C-specific code to deduce size of
3453 array from initialization.
3454 (complete_array_type): Just make it abort.
3456 * except.c (finish_handler_array): Avoid calling C-specific kludge
3457 complete_array_type.
3459 * convert.c (digest_constructor): Rename, and re-write to:
3460 (digest_array_tuple, convert): No longer use the code in
3461 ../c-typeck.c; use a Chill-only implementation (sigh).
3463 * typeck.c (chill_expand_tuple): Remove unneeded call to
3464 complete_array_type.
3466 * expr.c (fold_set_expr), grant.c (decode_constant),
3467 typeck.c (expand_constant_to_buffer): Update name of called
3468 function unpack_set_constructor to get_set_constructor_bits.
3469 * expr.c (powersetlen ): Remove redundant call to convert.
3471 * ch-tree.h (unpack_set_constructor): Removed obsolete declaration.
3473 * inout.c (build_chill_writetext): Handle 64-bit integer literals
3474 by trying to convert them to a smaller type.
3476 * lex.l (convert_number): Always use long long type (possibly
3477 unsigned) to avoid problems with constant folding truncation.
3479 Mon Sep 5 08:08:22 1994 Wilfried Moser (moser@rtl.cygnus.com)
3481 * ch-tree.h (enum chill_built_in_function): Add BUILT_IN_QUEUE_LENGTH.
3482 Add new prototype (see tasking.c).
3484 * expr.c (build_generalized_call): Add processing of
3485 BUILT_IN_QUEUE_LENGTH.
3487 * tasking.c (build_queue_length): New function.
3489 * tasking.c (tasking_init): Add new external function definition.
3491 Thu Sep 1 15:38:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3493 * lex.l (default_lex): New function. Progress towards
3494 getting rid of [f]lex.
3496 * lex.l (convert_number): Use mul_double and add_double.
3497 Set result type to a reasonable type in which the literal
3498 will fit. Give error message if literal is too big.
3500 * lex.l (equal_number): Switch (temporarily) to permanent obstack.
3502 * typeck.c (build_chill_slice_with_range): Check for empty
3503 slice *after* we have checked for upper/lower limit in range.
3505 * grant.c (decode_mode): Remove unused code. (BOOL and
3506 CHAR ranges are represented as INTEGER_TYPEs.)
3508 * tasking.c (build_process_header): Add missing call to
3509 expand_start_bindings.
3510 * parse.c (end_function): Add missing expand_end_bindings.
3512 Wed Aug 31 17:25:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3514 * decl.c (init_decl_processing): Set set_alignment.
3516 Tue Aug 30 16:40:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
3518 * actions.c (print_missing_cases, check_missing_cases,
3519 BITARRAY_TEST, BITARRAY_SET): New functions and macros,
3520 to check for completeness of case actions and expressions.
3521 * decl.c (c_decode_option, init_decl_processing):
3522 Don't set warn_switch.
3523 * expr.c (chill_expand_case_expr): Call check_missing_cases
3524 instead of check_for_full_enumeration_handling.
3525 * parse.c (parse_case_actions): Call check_missing_cases.
3527 * expr.c (build_chill_binary_op): Remove some dead code.
3528 * expr.c (chill_truthvalue_conversion): Call build_chill_binary_op
3529 instead of build_binary_op.
3530 * ch-tree.h (binary_op_error, build_binary_op): Unused. Removed.
3532 * parse.c (end_function): Use kept_level_p in parameter to
3533 poplevel. This reverts a June 13 change.
3535 Fri Aug 26 11:50:19 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3537 * configure: Ignore --without, as ../configure does.
3539 Wed Aug 24 01:17:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3541 * lex.l: Change rule for decimal numbers to allow identifiers
3542 to start with an underscore (_).
3544 Fri Aug 19 16:38:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
3546 * tasking.c (build_receive_signal_case_label): Remove backwards
3547 chill_convert_for_assignment (which converted whatever garbage
3548 was in the *target* to the type of the signal argument!).
3550 Fri Aug 19 07:10:43 1994 Wilfried Moser (moser@rtl.cygnus.com)
3552 * inout.c (build_chill_io_list_type, build_enum_tables),
3553 tasking.c (build_tasking_struct): Temporarily reset
3554 maximum_field_alignment to 0, so that the compiler-built
3555 data structures needed by the RTS can be independent of -fpack.
3557 Thu Aug 18 13:39:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3559 * typeck.c (build_init_struct): Temporarily reset
3560 maximum_field_alignment to 0, so that the compiler-built
3561 data structures needed by the RTS can be independent of -fpack.
3563 Wed Aug 17 23:48:33 1994 Wilfried Moser (moser@rtl.cygnus.com)
3565 * parse.c (parse_primval, expect, parse_on_exception_list):
3566 Print error message only in pass 2.
3568 Wed Aug 17 13:47:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3570 * decl.c (switch_to_pass_2): Revert June 13 change,
3571 (Don't exit after pass 1 if an error was found.)
3573 * ch-tree.def (SLICE_EXPR): New tree-code.
3574 * typeck.c (build_chill_slice): For building a slice of a
3575 bit-string, just generate a SLICE_EXPR.
3576 * decl.c (init_decl_processing): Declare __pscpy.
3577 * actions.c (chill_expand_assignment): Handle a SLICE_EXPR
3578 on the LHS of assignment, by calling __pscpy.
3579 * expr.c (chill_expand_expr): Handle SLICE_EXPR (as a RHS
3580 value) by using __psslice to copy slice to a temp.
3582 Wed Aug 17 05:52:44 1994 Wilfried Moser (moser@rtl.cygnus.com)
3584 * Make-lang.in: Change version of GNUCHILL compiler to 1.4.1.
3585 * expr.c (build_chill_length): Enable LENGTH built-in to process
3586 Buffers and Events too (Z.200/1992).
3587 * lex.l (yywrap): Always set yyin to finput and/or grt_in. On
3588 a linux system the previous version was not able to run.
3589 * tasking.c: Correct processing of infinite buffer- and event-length
3590 to avoid RANGEFAIL warning.
3592 Thu Aug 11 11:46:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3594 * parse.c (parse_if_expression_body): Don't call the C-specific
3595 build_conditional_expr. Just do build_nt (COND_EXPR, ...).
3596 * convert.c (convert): Convert a COND_EXPR by converting
3597 each branch.
3599 * convert.c (convert): Don't call convert before
3600 convert_to_reference. It's apt to do weird and unneedful things.
3601 * convert.c (convert): If the expression is varying, just call
3602 varying_to_slice, which simplifies quite a bit.
3604 * ch-tree.h (varying_to_slice): Add prototype.
3605 * typeck.c (varying_to_slice): Remove prototype.
3607 * satisfy.c (satisfy): Move case PAREN_EXPR from type 'e'
3608 to type '1'.
3610 * except.c (emit_setup_handler): Temporarily reset the
3611 maximum_field_alignment to zero so the compiler's exception
3612 data structures can be compatible with the run-time system,
3613 even when we're compiling with -fpack.
3615 * expr.c (compare_records): Call saved_if_needed on operands.
3617 * expr.c (build_set_expr case NE_EXPR): Don't use __nepowerset
3618 which has been reimplemented to just call __eqpowerset and
3619 invert the result. Inline this new implementation by
3620 handling as EQ_EXPR, and inverting the result.
3621 * decl.c (init_decl_processing): Don't define unused __eqpowerset.
3623 * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
3624 type boolean_type_node, not void_type_node. (Fixing this
3625 avoids a crash in the back-end.)
3627 * grant.c (decode_constant): In a CALL_EXPR, if the argument
3628 list is not a TREE_LIST (as in string repetiation), don't
3629 emit parentheses.
3631 Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
3633 * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
3634 CONST_DECL is from a SET definition. (This is safer than
3635 checking that the type is ENUMERAL_TYPE, because synonym
3636 definitions may have a NULL TREE_TYPE.)
3637 Also, if we have duplicate enums whose types are identical,
3638 this is an error.
3639 * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
3640 an extra 'quiet' parameter, which is true if we're called from
3641 bind_sub_modules. (In that case an error message about duplicated
3642 decls would be repeated later, so suppress it.)
3644 * parse.c (stmt_count): Removed, not used.
3645 (INIT_ACTION): Call emit_line_note only if !ignoring.
3646 (parse_begin_end_block): Do INIT_ACTION even if ignoring.
3648 Fri Aug 5 12:39:11 1994 Per Bothner (bothner@kalessin.cygnus.com)
3650 * parse.c (parse_untyped_expr): Add missing semi-colon.
3652 Thu Aug 4 17:40:38 1994 Per Bothner (bothner@kalessin.cygnus.com)
3654 * parse.c (parse_untyped_expr): Fix various problem for the
3655 case that we see a '(': Add missing 'case' keyword.
3656 Only recurse if '(' is followed by 'if', 'case' or '[',
3657 and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
3659 * parse.c (parse_send_action): Remove extra nreverse.
3661 Thu Jul 28 04:00:11 1994 Wilfried Moser (moser@rtl.cygnus.com)
3663 * expr.c (build_allocate_global_memory_call, build_allocate_memory_call):
3664 Add new checks.
3666 Tue Jul 26 22:48:15 1994 Michael Tiemann (tiemann@blues.cygnus.com)
3668 * parse.c (parse_untyped_expr): Added missing "case" before LPRN.
3669 Added a missing call to `require' as well.
3671 Tue Jul 19 10:30:12 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3673 * lex.l (yywrap): Define as yywrap_chill to avoid conflicts with
3674 the extern declaration in the flex skeleton.
3676 Mon Jul 18 23:06:04 1994 Per Bothner (bothner@kalessin.cygnus.com)
3678 * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
3679 Check the type of the instance expr using CH_COMPATIBLE,
3680 and not just == instance_type_node. (This allows
3681 the expression to have mode READ INSTANCE).
3682 * tasking.c (build_instance_type): Give instance_type_node
3683 a non-null novelty (i.e. different from a struct).
3684 * tasking.c (build_receive_case_start, build_delay_case_start):
3685 Check that for a location using CH_LOCATION_P.
3687 Mon Jul 18 13:22:23 1994 Jim Wilson (wilson@sphagnum.cygnus.com)
3689 * expr.c (finish_chill_unary_op): Use TREE_SET_CODE not TREE_CODE
3690 to modify a tree code.
3692 Mon Jul 18 11:24:57 1994 Bill Cox (bill@rtl.cygnus.com)
3694 * convert.c (digest_structure_tuple): Fix thinko in TREE_CODE
3695 comparison.
3697 Mon Jul 18 05:40:15 1994 Doug Evans (dje@canuck.cygnus.com)
3699 * decl.c (warn_bad_function_cast): Define so cc1chill will link.
3701 Thu Jul 14 18:37:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3703 * parse.c (parse_send_action): Do tree_cons *before* checking
3704 for end of loop.
3706 Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
3708 * convert.c (digest_structure_tuple): Don't use convert to
3709 coerce initial value, use chill_convert_for_assignment instead.
3710 (Thus we also get range_checking.)
3712 * expr.c (build_chill_card): Use force_addr_of instead of
3713 build_chill_addr_expr.
3715 * loop.c (build_temporary_variable): Stylistic tweak.
3716 * loop.c (maybe_make_for_temp): Initialize temp using
3717 explicitly, not using assignment. Avoids a problem if
3718 the expression is read-only.
3719 * typeck.c (smash_dummy_type): Always used the saved TYPE_NAME
3720 and CH_NOVELTY_FLAG.
3722 Wed Jul 6 20:12:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3724 * expr.c, ch-tree.h (finish_chill_unary_op): New function,
3725 based on code ripped out of build_chill_unary_op.
3726 (build_chill_unary_op): Call finish_chill_unary_op unless pass==1.
3727 * satisfy.c (satisfy): Call finish_chill_unary_op when needed.
3729 Mon Jun 27 11:29:18 1994 Per Bothner (bothner@kalessin.cygnus.com)
3731 * tree.c (save_if_needed), ch-tree.h: New function.
3732 * typeck.c (build_chill_slice_with_range,
3733 build_chill_slice_with_length): Call save_if_neeed on array arg.
3734 * expr.c (varying_to_slice): Re-write to use save_if_needed.
3736 * typeck.c (extract_constant_from_buffer): Handle BOOLEAN_TYPE.
3738 Mon Jun 27 01:11:10 1994 Wilfried Moser (moser@rtl.cygnus.com)
3740 * inout.c (build_chill_io_list_type): Change layout of __tmp_WIO_list
3741 that it is always the same, regardless if compiled with -fpack
3742 or not.
3744 Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
3746 * lex.l (yywrap): Kludge to work around mis-synchronization
3747 between lexer (which read ahead) and parser: Don't emit
3748 (left-over) uze_seizefile directives at the end of file.
3750 * typeck.c (build_chill_array_ref): Allow the derived
3751 array indexing syntax for arrays of bit strings.
3752 Add a comment explaining why.
3754 * typeck.c, ch-tree.h (string_assignment_condition): Change
3755 the interface. Return a boolean expression (which can be
3756 used in a conditional at run-time); never expand anything.
3758 * actions.c (chill_convert_for_assignment): Check
3759 string_assignment_condition here, rather than in callers.
3760 * actions.c (chill_expand_assignment): Don't need to check
3761 string_assignment_condition here.
3762 * expr.c (build_chill_function_call): Likewise.
3763 * satisfy.c (safe_satisfy_decl): Update accordingly.
3764 * decl.c (do_decl): Simplify testing and conversion by
3765 deferring everything to chill_convert_for_assignment.
3767 * parse.c: Combine the two variables 'ignore_exprs' and
3768 'ignore_actions' into one variable called 'ignoring'.
3769 * ch-tree.h: Add 'extern int ignoring'.
3770 * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
3771 Rename ignore_actions and ignore_exprs to ignoring.
3772 Remove unneeded extern declarations.
3773 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
3774 build_chill_arrow_expr, build_generalized_call, build_delay_action,
3775 build_buffer_type, build_event_type): I changed my mind. It is
3776 cleaner to check for 'ignoring' in the parser, rather than here.
3777 * parse.c (parse_action, parse_primval, parse_opt_mode):
3778 Therefore we must check for ignoring here.
3779 * parse.c (parse_loc_declaration): Set ignoring in pass 2
3780 when parsing the mode.
3782 * tasking.c (generate_tasking_code_variable): Do arithmetic
3783 on signal_code etc using unsigned rather than signed shorts.
3785 * grant.c (static char* current_grant_modename): Removed.
3786 * grant.c (decode_decl case CONST_DECL): Remove error message.
3788 * Make-lang.in (CHILL_SRCS): Add $(srcdir)/ch/parse.c.
3789 * Makefile.in: Fix dependencies for parse.o.
3790 Remove some duplicate dependencies for $(TREE_H).
3792 Mon Jun 13 14:25:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
3794 * typeck.c (build_chill_cast): Allow a value cast between
3795 non-discrete object of the same size, but with a pedwarn.
3796 * typeck.c (bit_string_assignment_condition,
3797 char_string_assignment_condition): Merge near-duplicate functions
3798 and place the code in string_assignment_condition.
3800 * decl.c (parm_flag, declare_parm_level, in_param_level_p):
3801 Removed. Not used.
3802 * decl.c (start_chill_function, finish_chill_function): Make
3803 parameter level have same nesting level as body, as required by Z200.
3804 * decl.c (switch_to_pass_2): Always exit if an error has been found.
3805 * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
3806 generated from GRANT ALL.
3807 * decl.c (lookup_name_for_seizing): Don't seize from
3808 the nesting level of builtins (predefined objects).
3809 * decl.c (lookup_name_for_seizing): Make more robust on error.
3811 * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
3812 be 'RESULT' (or 'result'). This makes it more accessible from gdb.
3813 Also, use do_decl to declare it, so that debugging symbols are
3814 generated. And, re-arrange so that actions that need to
3815 be done both passes (such as push_levels) use the same code.
3817 * parse.c (get_type_of): If ignore_exprs, don't lookup name.
3818 * parse.c (end_function): Fix poplevel params.
3819 * parse.c (expect): Don't read forwards on an error.
3820 * parse.c (parse_field): Don't define two tag_list locals!
3821 * parse.c (parse_pass_1_2): Better error message.
3823 * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
3824 parse_opt_mode, rather than vice versa. If parse_opt_mode
3825 returns NULL_EXPR, then parse_mode gives an error.
3826 Change parse_opt_mode (and any functions it calls) to only
3827 return NULL_TREE if there is no mode (even on ignore_exprs).
3828 (parse_set_mode, parse_structure_mode, parse_procedure_mode):
3829 Never return NULL_EXPR.
3830 * tasking.c (build_buffer_type, build_event_type): Return
3831 void_type_node instead of NULL_EXPR if ignore_exprs is true.
3833 * parse.c (parse_synonym_definition): Call parse_untyped_expr
3834 only if we have a mode.
3835 * parse.c (parse_send_action): Parse list of untyped_expr's,
3836 rather than a list of (typed) expressions.
3837 * parse.c (parse_primval): Emit error if '[' seen without
3838 preceding mode name. (If this is to be allowed, call
3839 parse_untyped_expr instead.)
3841 * parse.c (parse_array_index): Renamed to ...
3842 (parse_index_mode): ... to match Z200 terminology.
3843 Re-write to resolve some of the nastier ambiguities,
3844 and allow things like ' CHAR(10) : CHAR(20) '.
3846 * parse.c (parse_tuple_element): Change interface to return
3847 reversed list, so don't call nreverse.
3848 * parse.c (parse_tuple): No longer nreverse element list here.
3849 * parse.c (parse_opt_element_list): Do nreverse here instead.
3850 * parse.c (parse_case_label_list): Call nreverse at end.
3852 Fri Jun 10 15:36:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
3854 * typeck.c (chill_similar): Remove bogus "else".
3856 Wed Jun 8 00:01:40 1994 Per Bothner (bothner@kalessin.cygnus.com)
3858 * ch-tree.h (TYPE_ARRAY_MAX_SIZE): New macro (and comment)
3859 to make it clearer that we are using TYPE_MAX_VALUE in a special way.
3860 * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
3861 * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
3862 * convert.c (convert): When converting a fixed string/array
3863 to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
3864 of (the type of) the padding.
3865 * convert.c (convert): If the concatenation is non-constant, use
3866 the low-level 'build' to set the type of the result (which is usually
3867 a fixed-size array) rather than depend on build_chill_binary_op
3868 to figure it out (it's unable to simplify the size to a constant).
3870 Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
3872 * lang.c (lang_decode_option): Let -fspecial_UC imply
3873 -fno-ignore-case without requiring it explicitly.
3874 * lang.c (lang_decode_option): Support (experimentally)
3875 the -fpack and -fno-pack flags.
3877 Thu Jun 2 20:49:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3879 * configure: Add support for --program-prefix and --program-suffix.
3881 Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
3883 * convert.c (digest_constructor): Check that initial value
3884 is compatible with element mode before calling convert.
3885 * typeck.c (chill_compatible): A string mode is not compatible
3886 with an untyped constructor.
3887 * decl.c (do_decl): Clean up error messages. Use error_with_decl.
3889 * ch-tree.h: Fix inconsistencies: bool_true_node ->
3890 boolean_true_node, and bool_false_node -> boolean_false_node.
3891 * typeck.c (valid_array_index_): Minor simplification.
3893 Tue May 31 04:33:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3895 * inout.c (build_chill_writetext): Add correct processing
3896 of POWERSET RANGE (setmode).
3898 * lex.l (same_file): Add searching for file(s) in
3899 seize_path_list.
3901 Fri May 27 14:22:42 1994 Per Bothner (bothner@kalessin.cygnus.com)
3903 * Make-lang.c (CHILL.mostlyclean, CHILL.distdir): Don't list
3904 yacc/bison output files, since the grammer is no longer in yacc.
3905 * config-lang.in (diff_excludes): Likewise.
3907 Thu May 26 16:38:13 1994 Per Bothner (bothner@kalessin.cygnus.com)
3909 * gperf, hash.h, lex.l, parse.h: Rename PROCESS_TYPE token
3910 (in some files spelled PROCESS_TYPE_ to avoid clashes
3911 with the PROCESS_TYPE tree_code) to PROCESS_TYPE_TOKEN.
3913 Thu May 26 02:18:28 1994 Wilfried Moser (moser@rtl.cygnus.com)
3915 * timing.c (build_cycle_start): Change call to __define_timeout.
3916 * decl.c (init_decl_processing): Change definitions of
3917 __define_timeout and __wait_timeout.
3919 Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
3921 Replace yacc-based parser with a recursive-decent parser.
3922 (This may seem backwards, but Chill [like C++] is not a
3923 language that is remotely LALR(1). Using a R-D parser
3924 allows us to use look-ahead and to back-up to resolve the
3925 difficult ambiguities.)
3926 * parse.y: Removed.
3927 * parse.c, parse.h: New files, containing new r-d parser.
3928 * Makefile.in: Update accordingly.
3929 * actions.c (chill_convert_for_assignment): Don't return
3930 NULL_EXPR if ignore_exprs is true. It simplifies the parser
3931 if we consistently reserve NULL_EXPR for a missing expression.
3932 * expr.c (build_chill_function_call): Likewise.
3934 * lex.l: Tweaks for new parser.
3935 * lex.l (prepare_paren_colon, paren_paren_colon_level,
3936 paren_level): Ugly hack no longer needed.
3938 * expr.c (build_chill_function_call): Cleanup.
3939 Call chill_convert_for_assignment to convert IN/INOUT
3940 paramaters on both input and output. For LOC parameters,
3941 give error if actual is a non-referable location.
3942 * actions.c (convert_for_assignment): Add new parameter (a
3943 "place" string used in error messages).
3944 * actions.c (adjust_parm_or_field): Removed.
3945 * actions.c (chill_expand_assignment): Take just a single LHS,
3946 and move support for multiple assignments to ...
3947 (expand_assignment_action): ... here. Some cleaning up.
3948 * timing.c (build_cycle_start): Adjust accordingly.
3949 * actions.c (expand_assignment_to_varying_array): Likewise.
3950 * tasking.c (many places): Ditto.
3951 * ch-tree.h: Fix declarations appropriately.
3953 * parse.c (parse_defining_occurrence_list): Return a single
3954 IDENTIFIER_NODE (instead of a singleton list) in the common
3955 case. Minor complication to save a minor amount of space.
3956 * decl.c (do_based_decls): Move guts of code into ...
3957 (do_based_decl): ... this new function.
3958 * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
3959 * decl.c (push_syndecl): Replace by ...
3960 (push_syndecl): ... (which only supports a single name).
3961 (push_modedef): Only handle a single name.
3962 * tasking.c (build_process_header, build_signal_struct_type):
3963 Adjust accordingly.
3965 * expr.c (build_generalized_call): Handle string repetition.
3966 * expr.c (build_chill_repetition_op): Change interface.
3967 * grant.c (decode_constant): Allow parameter list to be
3968 a non-TREE_LIST. (Used for string repetition.)
3970 Wed May 25 11:28:48 1994 Per Bothner (bothner@kalessin.cygnus.com)
3972 * lex.l (make_identifier): Replaced by ...
3973 (read_identifier, handle_name): ... new functions.
3974 * lex.l: Parse an identifiers using read_identifier using
3975 read_identifier and handle_name, rather than having [f]lex
3976 do it. (One reason is that lex uses a fixed-size buffer.)
3978 * lex.l (read_directive, skip_directive): New functions.
3979 Use them to parse compiler-directives, instead of rather
3980 ugly and useless use of lexer start conditions.
3982 Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
3984 * decl.c (unnamed_module_number): Renamed to ...
3985 (module_number): .. and make non-static.
3986 (push_module): Always increment module_number.
3987 * lex.l (yywrap): Print warning if no modules seen.
3989 * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
3990 decl to current_seizefile_name (which is unreliable).
3991 * grant.c (chill_grant): Set it here instead.
3993 * expr.c (fold_set_expr): Use int_size_in_bytes instead of
3994 TYPE_PRECISION (which is not defined for a SET_TYPE).
3996 Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
3998 Cleanup to remove need for variables in common storage.
3999 * decl.c: Remove unused use of current_obstack.
4000 * actions.c (maybe_chill_check_decl): Remove unused function.
4001 * actions.h, lang.c: Remove uses of doing_chill_thang.
4002 * ch-tree.h (void_list_node): Make extern (rather than common).
4003 * decl.c (void_list_node): Add definition.
4005 Thu May 19 06:54:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
4007 * configure (build): Build canon_host and canon_target
4008 to pass it to all subsequently generated Makefiles (needed
4009 for testsuite/execute in case of cross build).
4011 Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4013 * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
4014 the input type, which loses with the no-longer-new 2-pass
4015 implementation, since the input "type" could be an IDENTIFIER_NODE.
4016 * grant.c (raw_decode_mode): Rename to decode_mode.
4018 Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
4020 * typeck.c (chill_location): Neither a STRING_CST nor a
4021 CONSTRUCTOR is a location.
4022 * typeck.c (chill_root_mode): Convert a function to a
4023 pointer-to-function.
4024 * expr.c (build_chill_indirect_ref, build_chill_component_ref,
4025 build_chill_arrow_expr): If ignore_exprs, return operand
4026 rather than NULL_EXPR. This makes it easier for the parser to
4027 distinguish missing expressions.
4028 * expr.c (build_max_min): Convert the lower bound of a
4029 set to a long before calling run-time routine.
4030 * expr.c (build_chill_pred_or_succ): Use discrete_type_p
4031 to check the argument type.
4032 * expr.c (build_chill_arrow_expr): If argument is not a location,
4033 do a predwarn if it is a STRING_CST or has function type.
4035 Tue May 17 06:05:13 1994 Wilfried Moser (moser@rtl.cygnus.com)
4037 * configure (build): Remove building of canon_host and canon_target.
4038 It doesn't work in any case.
4040 Mon May 16 02:10:35 1994 Wilfried Moser (moser@rtl.cygnus.com)
4042 * configure (build): Build canon_host and canon_target
4043 to pass it to all subsequently generated Makefiles (needed
4044 for testsuite/execute in case of cross build).
4045 * Make-lang.in (chill-runtime): Change chill to CHILL in the case
4046 statement to build chill-runtime automatically.
4048 Mon May 9 15:30:08 1994 Doug Evans (dje@canuck.cygnus.com)
4050 * Makefile.in (FLAGS_TO_PASS): Define.
4051 (OBJDEPS): Define.
4052 (../cc1chill): Depend on $(OBJDEPS) $(C_OBJS).
4053 * Make-lang.in (cc1chill): Delete dependency on $(OBJS) $(BC_OBJS).
4054 (CHILL.mostlyclean): Use `mostlyclean' as recursive target.
4056 Sun May 8 13:05:00 1994 Per Bothner (bothner@cygnus.com)
4058 * Make-lang.in (cc1chill): Should not depend on libgcc.a.
4060 Thu May 5 18:58:22 1994 Per Bothner (bothner@kalessin.cygnus.com)
4062 * decl.c (copy_lang_decl): New (dummy) function.
4064 Mon May 2 14:33:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
4066 * parse.y (sendaction): Fix thinko (in sense of condition).
4067 * tasking.c (build_receive_case_label): Another thinko.
4069 * parse.y (optsigdest): Force ignore_exprs to 0 while parsing
4070 the (signal-)name.
4072 * decl.c (build_chill_function_type): Don't call layout_type
4073 (since that may prevent parameter or result types being
4074 properly satisfied).
4075 * satisfy.c (satisfy): Layout FUNCTION_TYPEs.
4076 * parse.y (procmode): Call build_chill_pointer_type, rather
4077 than build_pointer_type (which incorrectly sets TYPE_SIZE).
4079 * parse.y (get_type_of): Handle TYPE_DECL (again).
4080 * parse.y (optresultspec): Call build_chill_reference_type, rather
4081 than build_reference_type (which incorrectly sets TYPE_SIZE).
4082 * parse.y (range_or_mode): Rename to plain range, since it
4083 no longer matches modename.
4084 * actions.c (chill_handle_case_label_range): New function, with
4085 functionality moved out of chill_handle_case_label.
4086 * actions.c (chill_handle_case_label): Handle here the case that
4087 the label_value is a TYPE_DECL (modename). Also clean up some.
4088 * typeck.c (build_chill_slice_with_length): Convert max_index
4089 to the type of min_value. (Old code broke on varying strings.)
4091 Sun May 1 13:53:36 1994 Doug Evans (dje@canuck.cygnus.com)
4093 * Makefile.in (BC_OBJS): Delete all references
4094 (OBJS): Cat ../stamp-objlist to get language independent files.
4095 (../cc1chill): Delete dependency on $(OBJS).
4096 * Make-lang.in (cc1chill): Depend on stamp-objlist.
4098 Sat Apr 30 14:50:15 1994 Per Bothner (bothner@kalessin.cygnus.com)
4100 * lex.h, lex.c: Remove lastiddecl.
4101 * lex.l (name_type_signal): Simplify. We no longer check for
4102 TYPENAME or SIGNALNAME (which was unreliable with two passes).
4103 Also rename to make_identifier.
4104 * parse.y: Cleaned up grammar to not need SIGNALNAME or TYPENAME.
4105 * Makefile.in (stamp-parse); One conflict fewer!
4106 * parse.y (rccase_label_flag): Moved to tasking.c.
4107 * parse.y (rccase_label): Move most of the logic to
4108 build_receive_case_label in tasking.c.
4109 * parse.y (sendaction): Re-write to not depend on SIGNALNAME.
4111 * parse.y (name): Do name lookup here (and not in location).
4112 * parse.y: Replace most uses of NAME by higher-level non-terminals:
4113 simple_name_string, name_string, defining_occurrence, or name.
4115 * tasking.c (build_receive_signal_case_label,
4116 build_receive_buffer_case_label): New functions, split out from
4117 build_receive_case_label.
4118 * tasking.c (build_receive_case_label): Change parameters
4119 and return type. Moved stuff here (from the parser).
4120 * tasking.c (struct rc_state_type): Removed had_errors.
4121 Return error_mark_node instead.
4122 * tasking.c (build_rccase_set_error), ch-tree.h: Removed.
4124 * expr.c (build_generalized_call): If func is a signal type,
4125 call build_signal_descriptor.
4127 * parse.y (arrayindex): Renamed to index_mode, to match Z.200.
4128 * parse.y (ioindexmode): Removed; use index_mode instead.
4129 * expr.c (build_generalized_call): If args is a RANGE_EXPR,
4130 we have either a slice or a range mode, depending on func.
4131 * parse.y (index_mode): If we got an 'expr', only allow a name,
4132 or a range mode.
4133 * parse.y (call): A slice with both end points can be a range
4134 mode, so defer handling to build_generalized_call (or index_mode).
4136 * typeck.c (build_chill_slice_with_length): Fix type-checking.
4137 * typeck.c (chill_novelty): Undo (part of) change of April 28:
4138 The novelty of a range mode is the novlety of the parent.
4139 * typeck.c (chill_root_mode): Don't return integer_type_node
4140 if argument has non-nil novelty.
4142 * decl.c (global_bindings_p): Return -1 as true, for the sake
4143 of variable_size (in ../stor-layout.c).
4145 Fri Apr 29 13:42:43 1994 Per Bothner (bothner@kalessin.cygnus.com)
4147 * parse.y: Remove TYPENAME and modename. These are now plain
4148 NAMEs. Modify parsing actions appropriately.
4149 * expr.c (build_generalized_call): Handle the case that
4150 TREE_CODE (func) == TYPE_DECL (as in a cast).
4151 * lex.l (name_type_signal): Never return TYPENAME.
4152 * parse.y (get_type_of): If pass 1, just return the argument.
4154 * decl.c (do_decl): If an initializer has the wrong type,
4155 replace it by NULL_TREE, to avoid subsequent errors.
4157 Thu Apr 28 15:21:56 1994 Wilfried Moser (moser@rtl.cygnus.com)
4159 * Makefile.in: Add new file timing.c to rules.

4165 add check agains an IDENTIFIER_NODE.
4166 * gperf, hash.h: Change EVENT_CODE, BUFFER_CODE to IGNORED_DIRECTIVE.
4167 They are no longer needed.
4168 * grant.c (print_integer_type): Add processing of builtin types
4169 DURATION and TIME.
4170 * lex.l: Remove processing of directive EVENT_CODE & BUFFER_CODE.

4186 * tasking.c (build_receive_buffer_case_end, build_receive_signal_case_end):
4187 New functions to process the end of a RECEIVE CASE action in case
4188 of BUFFER's and SIGNAL's.
4189 * tasking.c (build_receive_case_end): Do only general processing and
4190 call one of the above mentioned functions.
4191 * tasking.c (build_delay_case_start, build_delay_case_label,
4192 build_delay_case_end): Rewritten due to new implementation of events.
4193 * tasking.c (build_delay_action): Rewritten due to new implementation
4194 of EVENT's.

4197 ch-tree: New functions.
4199 Thu Apr 28 14:11:29 1994 Per Bothner (bothner@kalessin.cygnus.com)
4201 * typeck.c (smash_dummy_type): Handle the special case of a
4202 NEWMODE of a range mode, as required by Z200, by creating a
4203 new parent mode with the new novelty (and casting the min
4204 and max of the range to teh new parent mode).
4205 * typeck.c (chill_novelty, chill_root_mode): Remove special
4206 kludges for of NEWMODE ranges.
4207 * expr.c (build_chill_lower_or_upper): New function, combining
4208 the "guts" of build_chill_lower and build_chill_upper.
4209 * expr.c (build_chill_lower_or_upper): Simplify; no longer
4210 need to kludge the novelties.
4212 * typeck.c (valid_array_index_p): A string index expression
4213 need not be Compatible with the index type; only similar.
4215 * decl.c (layout_chill_variants): If error seen, skip stuff
4216 (rather than aborting or crashing).
4217 * decl (push_modedef): If newdecl's type is an error mark,
4218 continue rather than aborting.
4220 Thu Apr 28 02:07:42 1994 Doug Evans (dje@cygnus.com)
4222 * Make-lang.in: Update of directory reorg from fsf.
4223 * config-lang.in: Ditto.
4225 Mon Apr 25 13:09:46 1994 Per Bothner (bothner@kalessin.cygnus.com)
4227 * typeck.c (chill_similar): Check RECORD_TYPEs properly,
4228 * convert.c (convert): If all else fails, just call convert1.
4229 Thus we can now convert RECORD_TYPEs (assuming they are similar).
4231 * parse.y, lex.l: Remove BUFFERNAME (use location/expr instead).
4232 * parse.y: Re-do BUFFER handling (similar to previous EVENT change).
4233 * grant.c (raw_decode_mode): Re-do BUFFER mode handling.
4234 * ch-tree (lang_type_record): Removed max_queue_size field.
4235 * tasking.c (build_buffer_type): Re-write.
4236 * tasking.c (max_queue_size): Fix to support buffer modes.
4237 * tasking.c (buffer_element_mode), ch-tree.h: New function.
4238 * tasking.c ch-tree.h (expand_send_buffer): Now has 3 parameters.
4239 * parse.y (modename): No longer match SIGNALNAME. Instead, add it
4240 to name and simple_name_string. This removes a reduce/reduce conflict.
4241 * Makefile.in (stamp-parse): Expect fewer conlicts.
4243 * lex.l (yywrap): Move check for circularly seizeing current
4244 grant-file from here ...
4245 * lex.l (handle_use_seizefile_directive): ... to here.
4246 This is to avoid calling stat on a not-yet written grantfile,
4247 now that we're using same_file (which calls stat).
4248 * grant.c (set_use_this_gf): Removed.
4249 * grant.c (set_default_grant_file): Set grant_file_name here,
4250 because we need it earlier (due to above lexer change).

4404 a process argument has other attribute then IN or LOC.

4453 Clean up error message for OUT//INOUT not location to use only 1 line.
4454 Add error message for OUT/INOUT if type is READonly.
4455 * typeck.c (build_chill_modify_expr): Simplify.
4457 Sun Mar 27 19:30:25 1994 Bill Cox (bill@rtl.cygnus.com)

4491 Wed Mar 23 13:34:18 1994 Bill Cox (bill@rtl.cygnus.com)
4493 * expr.c (build_generalized_call): Revert previous change.
4494 To do this correctly, we need a new parsing mechanism, and
4495 C++ initializer technology.

4499 * expr.c (build_generalized_call): Be sure we're inside the

4557 Mon Mar 21 13:29:23 1994 Per Bothner (bothner@kalessin.cygnus.com)
4559 * typeck.c (layout_chill_range_type): Instead of tree_int_cst_lt
4560 use compare_int_csts (which is more robust when signedness differs).

4564 * expr.c (chill_expand_expr): Code to expand SET_IN_EXPR,

4568 Use SET_IN_EXPR in place of IN_EXPR.
4570 * expr.c (build_compare_discrete_expr), ch-tree.h: New function,
4571 with code moved from build_compare_expr.
4572 * expr.c (build_compare_expr): Re-enable compatibility test.

4589 (build_compare_expr): Comment out compatibility test - should

4596 list for __setbitpowerset,
4598 * typeck.c (chill_compatible_classes): Allow the M-reference
4599 to be compatible with the N-value class, with suitable M and N.
4600 * typeck.c (build_chill_slice): Don't smash a void TREE_TYPE.
4601 (We don't need to, and it causes confusion.)
4603 * expr.c (build_compare_expr): Fix thinko. Add save_exprs.
4605 * expr.c (build_compare_expr): Fix a transcription bug
4606 (for converting NULL INSTANCEs). Also #include convert.h.

4610 * expr.c (finish_chill_binary_op): Moved code dealing with
4611 the comparison operators from here ...
4612 * expr.c (build_compare_expr): ... to new function here.

4614 differing values of TYPE_PRECISION and TREE_UNSIGNED.
4615 the code from lay

4636 * expr.c (build_chill_pred_or_succ): Fix cond tree
4637 to have consistent operand types.
4638 * typeck.c (valid_array_index_p): Change interface to pass
4639 validity conditions back on caller's TREE_LIST. We
4640 cannot link the conditions to anything which a
4641 layout_type routine will expand, since that will occur
4642 before the exception handler is set up.
4643 Change calls to valid_array_index_p also.
4645 Fri Mar 18 14:40:50 1994 Per Bothner (bothner@kalessin.cygnus.com)
4647 * actions.c, except.c, loop.c, tasking.c: Call

4651 * loop.c (top_loop_end_check): Coerce library function arg.
4652 * convert.c, expr.c: Re-write to avoid calls to C-specific
4653 function build_unary_op (e.g. by calling build1 directly).
4655 * typeck.c (chill_equivalent): Change to force failure
4656 for non-matching integral types (even if not ranges).
4658 * typeck.c, ch-tree.h (build_chill_slice): Make non-static.
4659 * expr.c (varying_to_slice): Call build_chill_slice (and not
4660 build_chill_slice_with_length, which does bunches of range
4661 checking and does not allow the length to be zero).
4662 * convert.c (convert): Fix off-by-one error.
4663 * actions.c (chill_expand_array_assignment): Minor cleaning up.
4665 Fri Mar 18 00:12:48 1994 Per Bothner (bothner@deneb.cygnus.com)

4668 take *two* pointer parameters, not one.
4669 * satisfy.c (satisfy): Only call the appropriate layout routine
4670 if TYPE_SIZE is 0 (i.e. type hasn't already been laid out).
4671 * typeck.c (build_chill_slice_with_length): Fix Bill's previous fix.
4673 Thu Mar 17 17:29:43 1994 Bill Cox (bill@rtl.cygnus.com)

4676 type tree.
4677 * typeck.c (build_chill_slice_with_length): Restore dynamic range

4680 Wed Mar 16 17:23:31 1994 Per Bothner (bothner@kalessin.cygnus.com)
4682 * typeck.c (build_chill_slice), expr.c (chill_expand_expr
4683 [case CONCAT_EXPR]): Remove kludge setting slice size upper bound
4684 in TYPE_LANG_SPECIFIC, and restore kludge setting it in MAX_VALUE.
4685 * typeck.c (build_chill_slice): Use TYPE_MAX_VALUE of
4686 array_type if needed for size upper bound of slice_type.
4687 * expr.c (build_concat_expr): Improve calculation of size upper bound.
4689 * typeck.c (valid_array_index_p): Check compatibility using
4690 correct types.
4691 * typeck.c (build_chill_slice_with_length); For now revert
4692 calling valid_array_index_p on length. (It makes it harder
4693 to realize when the slice is constant length.)
4694 * expr.c (build_chill_indirect_expr): Minor tweak. (This
4695 seems to work around a weird C compiler bug. ??)

4711 * decl.c (init_decl_processing): layout boolean_type_node *after*
4712 we've set it's TYPE_MIN_VALUE and TYPE_MAX_VALUE.

4722 code to output error in only one pass.

4735 index validation.
4736 (build_hill_lower, build_chill_upper): Return value now inherits
4737 the novelty of the input parameter.
4738 (varying_to_slice): Use CH_NOVELTY macro rather than calling
4739 chill_novelty directly.
4740 * grant.c (newstring): Make len unsigned and cast xmalloc parameter
4741 to unsigned.

4757 is called to handle slices of varying arrays, rather than handling
4758 handling them here.
4759 (build_chill_slice_with_range, build_chill_slice_with_length):
4760 Check range limits for TREE_CONST before calling tree_int_cst_lt.

4765 * parse.y (modeless_expr): New rule to allow ([...]) and (if...)
4766 to count as untyped_exprs. (This is not really permitted by the
4767 Blue Book, but has been requested by customers.)
4769 Thu Mar 10 10:11:02 1994 Bill Cox (bill@rtl.cygnus.com)
4771 * chill.texi: Document new command-line options.

4780 * Makefile.in: Have rules to make parse.h, y.tab.c and other
4781 derived files. This allows the gcc/configure list of CHILL
4782 files machinery to work.
4783 * ch-tree.h (permanent_allocation): Add a parameter flag.
4784 * decl.c (finish_chill_function, finish_decl): Provide the
4785 new permanent_allocation flag.
4786 (poplevel): Return early, avoid a seg fault.
4787 * lex.l (NORMAL): Replace this whole state with the predefined
4788 INITIAL state. Force compilation state to global level after
4789 compiler directive error - prevents endless loop on error.
4790 (handle_use_seizefile_directive): Rewrite for readability.
4791 (chill_same_grant_file): Reindent.
4792 Generally handle whitespace differently.
4793 * regression.prpt: Print ten PR numbers per line. The report's
4794 getting too long.

4798 * decl.c (do_decl): Suppress the string-assignment-condition
4799 error - it was too often seen.
4800 * expr.c (expand_chill_expr): In CONCAT_EXPR, when argument has a
4801 runtime-changing length (as in a slice), get the parent array's
4802 allocation size from its type tree.

4813 some whitespace.
4814 * lex.l (name_type_signal): Add debug output.

4816 to a call, so that SIZE () works on them.
4817 * tasking.c (make_process_struct): Force ignore_exprs non-zero
4818 when processing a SEIZEd PROCESS declaration. This prevents
4819 grox-fixed_fields from returning a NULL, and indirectly protects
4820 the chill_integer_type_node tree from corruption.
4822 Mon Mar 7 19:14:05 1994 Bill Cox (bill@rtl.cygnus.com)
4824 * Makefile.in: Use the 'all' target to build the runtime

4831 register. Fixes the execute/inout.ch bug.
4832 * typeck.c (layout_chill_range_type): Restrict it
4833 from complaining about an empty string type's
4834 bounds (0:-1).

4838 * Makefile.in (compiler): Restore this target.
4839 (OBJS, BC_OBJS): Delete unused variables.

4869 * lex.l (INITIAL): Remove all code to discard 'header lines'.
4870 no longer needed.
4871 * parse.y (optheader): Remove - it's obsolete, as is the
4872 HEADEREL token definition.
4874 Fri Mar 4 09:41:18 1994 Bill Cox (bill@rtl.cygnus.com)
4876 * addtest: Fix suffix removal when suffix is .c186.

4971 name for correctness.
4973 Wed Feb 23 15:07:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
4975 New cleaner solution to the following problem:
4976 Chill allows an action to be followed by an ON-handler.
4977 But we don't know if an action has a handler until we've parsed
4978 its end, yet we want to generate extra code to set up an
4979 exception handling contour only if needed. The old solution
4980 would generate code for the action into an rtl sequence, and then
4981 splice in the exception-setup code if we later found we needed it.
4982 This has a few problems (for example it confuses the management
4983 of stack temporaries), and is ugly. Now that the compiler is 2-pass
4984 we have a cleaner solution: In pass 1, we remember which actions
4985 were followed by ON-handlers. In pass 2, we use this information
4986 to generate appropriate code before an action.
4987 * except.c (push_handler, pop_handler): In pass 1, set up data
4988 structures (global_handler_list) to remember if an action has an
4989 ON-handler. In pass 2, digest this information, and setup
4990 handler if needed.
4991 * except.c, actions.h (pop_handler): Take an extra int arg.
4992 * except.c (emit_setup_handler): New function, with code (moved
4993 from chill_start_on) to emit code before an action that has a handler.

4995 * parse.y (pass1_2): Call except_init_pass_2 before pass 2.
4996 * parse.y (POP_UNUSED_ON_CONTEXT): Don't call pop_sequence.
4997 * parse.y: Invoke POP_UNUSED_ON_CONTEXT and POP_USED_ON_CONTEXT
4998 in pass 1 as well as pass 2.
4999 * parse.y (BEGIN ... END): Re-arrange logic to avoid block_stack
5000 (local to ../stmt.c) getting out of sync.
5001 * actions.c (push_action): Don't need to emit a NOP,
5002 now that we're no longer moving sequences around.
5003 * actions.c (push_action): Call push_handler even in pass one.
5005 Wed Feb 23 11:06:14 1994 Bill Cox (bill@rtl.cygnus.com)

5066 sources.
5067 * typeck.c (string_assignment_condition): Allow a
5068 mis-match if the LHS is varying.

5112 * convert.c (convert): The same.
5114 * grant.c (decode_constant): Clean up. Remove remnants of switch

5637 * ch-actions.c, ch-expr.c, ch-inout.c: Use build_chill_array_ref_1
5638 instead of build_chill_array_ref where appropriate.
5639 * ch-actions.c, ch-expr.c, ch-typeck.c: Make operand 1 of a
5640 VARY_ARRAY_REF is a single index, not an index list.
5642 * ch-grant.c (__init_list): Renamed to _ch_init_list, to
5643 avoid a conflict on the Alpha.
5645 Wed Jan 12 10:19:35 1994 Bill Cox (bill@rtl.cygnus.com)
5647 * ch-lex.l (WS): Add BS, VT and CR to definition of
5648 whitespace.
5649 (convert_number): Allow for uppercase hex digits.
5651 Tue Jan 11 19:43:55 1994 Bill Cox (bill@cygnus.com)

5654 conditional so error messages are output.
5655 * ch-expr.c (build_chill_addr_expr): Add error message.
5656 * ch-grant.c (chill_finish_module_code): Avoid abort by
5657 giving the init_list constructor a type.
5658 (chill_finish_compile): Delete unused code.
5659 * ch-lex.l: Make most build_init_2 calls from the
5660 permanent obstack, so that enumeration values endure.
5661 * ch-loop.c (build_chill_iterator): Add several error
5662 messages.
5664 Tue Jan 11 12:31:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
5666 * ch-expr.c, ch-typeck.c: Rewrite some instances of
5667 'struct ch_class class = chill_expr_class (expr);' to
5668 'struct ch_class class; class = chill_expr_class (expr);'
5669 to work around a bug in /usr/ucb/cc on SunOS4.
5671 Mon Jan 10 18:29:36 1994 Bill Cox (bill@rtl.cygnus.com)
5673 * ch-actions.c (chill_convert_for_assignment): Avoid seg fault.
5674 * ch-expr.c (expand_packed_set): Add new parameter to pass
5675 set's minimum ordinal value. Fix loop invariant problem.
5676 (fold_set_expr): Change to add new parameter to
5677 expand_packed_set call.
5678 * ch-grant.c: Move extern declaration to ch-tree.h.
5679 * ch-lex.l (convert_bitstring): Also output the bitstring
5680 if yydebug is set.
5681 * ch-tree.h: Add prototype.

5694 Also, fix some bugs for bitstrings (with ranges).
5696 (Patches from Tiemann.)
5697 * ch-convert.c (convert1): New function to force TREE_TYPE.
5698 (convert): Use convert1 where appropriate.
5699 * ch-typeck.c: Formatting change.
5700 * ch-parse.y (build_chill_constructor): Fix thinko.
5702 * ch-expr.c (varying_to_slice): If array is not referable,
5703 call save_expr on it, rather than stabilize_reference.
5704 * ch-satisfy.c (safe_satify_decl, for CONST_DECL):
5705 Don't force value to value class if mode is not explicitly
5706 specified. Also, make sure convert etc is only done once.
5708 Sat Jan 8 16:37:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
5710 * ch-decl.c (build_chill_function_type): Don't call
5711 build_function_type, because it does hash canonicalization,
5712 which once in a while looses badly.
5713 * tree.c (build_function_type): Remove no-longer-needed test
5714 for doing_chill_thang.
5716 * ch-tree.h (CH_DERIVED_FLAG): New flag.

5727 * ch-decl.c (layout_enum): Mark enum values with CH_DERIVED_FLAG.
5728 * ch-lex.l (string_or_int): Rename to string_or_char.
5729 * ch-lex.l (build_chill_string, string_or_char, convert_bitstring,
5730 convert_float, convert_number): Set CH_DERIVED_FLAG for literals.
5731 * ch-expr.c (finish_chill_binary_op): Use convert_to_class.
5732 * ch-satisfy.c (safe_satisfy_decl): For CONST_DECL, make sure
5733 DECL_INITIAL gets set to result of convert.
5734 Also, clear CH_DERIVED_FLAG for SYN value.
5735 * expr.c (store_constructor): If a [power]set is exactly one
5736 word long, use single-word move.
5738 Sat Jan 8 08:38:29 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5740 * c-typeck.c (chill_initializer_constant_valid_p): Fix typo.
5742 Wed Jan 5 05:18:46 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5744 * ch-typeck.c (build_chill_slice_with_length): Test that ARRAY is of
5745 ARRAY_TYPE before assuming so. Also, subtract 1 from LENGTH in
5746 computation of SLICE_END.
5748 * ch-typeck.c (chill_location): Treat CONSTRUCTORs like STRING_CSTs.
5750 * ch-expr.c (build_chill_indirect_ref): Handle MODE == NULL_TREE.
5752 * ch-expr.c (fold_set_expr): Handle OP1 == NULL_TREE (which happens
5753 for unary set operations).
5755 * ch-expr.c (build_chill_array_expr): Take new argument FORCE. All
5756 callers changed. All callers changed.
5758 * ch-convert.c (digest_structure_tuple): Handle SELECTED_VARIANT
5759 being NULL_TREE until we've started walking the list of values via
5760 the loop over VARIANTs.
5762 * ch-parse.y (build_chill_constructor): If we see an IDENTIFIER_NODE,
5763 treat it as an enum value (and hence constant). Also, only set
5764 TREE_STATIC if the constructor is indeed constant.
5765 * c-typeck.c (chill_initializer_constant_valid_p): If we see a
5766 VAR_DECL, test the TREE_CONSTANT field of the DECL_INITIAL, don't
5767 recurse on the DECL_INITIAL.
5769 Wed Jan 5 01:24:50 1994 Bill Cox (bill@cygnus.com)
5771 * Makefile.in: Add CHILL to LANGUAGES variable.
5772 * ch-actions.c (check_range): Call build_binary_op instead of
5773 fold, build to get the common types chosen.
5774 (cond_range_exception, cond_overflow_exception,
5775 cond_type_range_exception): Delete, obsolete.
5776 (chill_convert_for_assignment): Enable this, get particular
5777 about when to generate rangecheck code.
5778 * ch-expr.c (build_chill_function_call): Sketch in where to
5779 perform chill_convert_for_assignment on actual parameters.
5780 (build_chill_addr_expr): Correct compiler warning.
5781 * ch-loop.c (build_chill_iterator): Add runtime check for
5782 negative loop step expression.
5783 * ch-tree.h: Add prototype.
5784 * ch-typeck.c (chill_max_vary_array_ref): Correct misunderstanding.
5785 A varying array's length field counts the NUMBER of active array
5786 array entries, not the byte-length of them.
5788 Tue Jan 4 17:57:39 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5790 * ch-decl.c (do_decl): Call `suspend_momenary' if the
5791 converted constructor must live on the permanent_obstack.
5792 * ch-convert.c (convert): When building a new SET_TYPE
5793 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5794 * c-typeck.c (chill_initializer_constant_valid_p): Handle VAR_DECLs.
5796 * ch-typeck.c (chill_location): CONSTRUCTORS that are static
5797 are locations.
5798 * ch-satisfy.c (safe_satisfy_decl): Convert DECL_INITIAL of CONST_DECL
5799 on permanent_obstack if necessary.
5801 * ch-convert.c (digest_structure_tuple): When building a new SET_TYPE
5802 constructor, re-set the TREE_CONSTANT and TREE_STATIC bits.
5804 * ch-decl.c (do_decl): Fix handling of REFERENCE_TYPEs which
5805 the patch below helped to mess up.
5807 * ch-expr.c (build_chill_arrow_expr): Call `mark_addressable'.
5808 (build_chill_addr_expr): Take new argument ERRORMSG.
5809 All callers changed. Also, call `build_chill_addr_expr' where
5810 we used to call `build1 (ADDR_EXPR, ptr_type_node, ...)' since
5811 that now calls `mark_addressable' automagically.
5813 * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.
5814 This is needed because variables may appear in initialization
5815 statements, and their DECL_INITIALs are their values at
5816 initialization time.
5817 * ch-convert.c (digest_structure_tuple,digest_constructor): Changed
5818 to handle VAR_DECLs as initializers.
5820 * ch-convert.c (digest_structure_tuple): Copy elements of INITS so
5821 they aren't destroyed for later use.
5823 Tue Jan 4 15:25:30 1994 Bill Cox (bill@cygnus.com)
5825 * ch-expr.c (chill_expand_expr): Correct check-range lo_limit
5826 parameter for varying_array_ref calculations.
5827 (build_chill_indirect_ref): Prevent seg fault due to syntax error.
5828 * ch-typeck.c (build_chill_slice_with_range): Correct issuance
5829 of bogus error in votrics.
5830 (build_chill_slice_with_length): Change for debug tracability.
5832 Tue Jan 4 02:43:37 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5834 * ch-convert.c (digest_structure_tuple): Fix phasing problem in
5835 handling variant record initializers.
5836 (various places): Change `pop_init_level' calls to match
5837 `push_init_level' wrt implicit variable.
5839 * ch-typeck.c (build_chill_slice): Convert the dynamic max index to
5840 `integer_type_node' before using it in comparisons. FIXME: should
5841 this be done in `chill_max_vary_array_index' by default?
5843 Tue Jan 4 00:24:14 1994 Bill Cox (bill@cygnus.com)
5845 * ch-actions.c: Fix comments.
5846 * ch-parse.y: Define caseaction_flag.
5847 (caseaction): Create new caseaction_flag node at the start,
5848 then free it at the end. Check it before the ELSE code.
5849 (expanded_case_label): Check the flag here. If set in either
5850 place, generate a jump to the end of the case.
5851 * ch-typeck.c (build_chill_slice_with_length,
5852 build_chill_slice_with_range): Add lots of compile-time
5853 parameter range checking.
5855 Mon Jan 3 21:49:04 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5857 * ch-convert.c (digest_structure_tuple): Call `push_init_level' with
5858 implicit==0 everywhere, not 1.
5859 (digest_constructor): Ditto.
5861 * ch-actions.c (check_range): Permit limits to be NULL_TREE.
5862 Also, hack out some dead code.
5863 * ch-typeck.c (build_chill_slice): Check varying and non-varying
5864 slice constructs for range failures.
5865 (build_chill_slice_with_range): Reindented, but not changed.
5867 * ch-typeck.c (chill_max_vary_array_index): New function.
5868 * ch-expr.c (chill_expand_expr): Call it.
5870 * ch-decl.c (var_data_id, var_length_id): New variables.
5871 (init_decl_processing): Initialize them. All calls to
5872 get_identifier (VAR_LENGTH or VAR_DATA) are now replaced
5873 by references to these variables. This simplifies the code
5874 w/o obscuring anything.
5876 Mon Jan 3 21:24:44 1994 Bill Cox (bill@cygnus.com)
5878 * c-typeck.c: Fix comment.
5879 * ch-actions.c (chill_expand_assignment): Error assigning to
5880 READONLY location. (PR_3903) Pass filename, linenumber
5881 to setbitpowerset runtime routine.
5882 * ch-decl.c (init_decl_processing): Add filename, linenumber
5883 parameters to setbitpowerset prototype.
5884 * ch-expr.c (build_chill_function_call): Error when passing a
5885 READonly location as a LOC or INOUT parameter.
5886 * ch-parse.y (mode): Correct code marking type as readonly.
5888 Mon Jan 3 19:03:55 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5890 * ch-actions.c (chill_expand_assignment): Disable code that defeats
5891 building varying array references.
5892 * ch-expr.c (chill_expand_expr): Add rangecheck code to
5893 VARY_ARRAY_REF case.
5894 * ch-typeck.c (build_chill_array_ref): Don't call an `expand_'
5895 function (in this case, `validate_varying_array_ref') when we're
5896 doing a `build_' operation.
5898 * ch-typeck.c (validate_varying_array_ref): Simplify interface
5899 since INDEX parameter can never meaningfully be an INDEXLIST.
5900 * ch-actions.c (expand_varying_length_assignment): Caller changed.
5902 Mon Jan 3 07:29:45 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5904 * ch-typeck.c (build_chill_cast): Set TREE_CONSTANT on NOP_EXPRs.
5905 * ch-convert.c (digest_structure_tuple): Switch to permanent_obstack
5906 if we need to build a CONSTRUCTOR for a SET_TYPE initializer.
5907 (digest_structure_tuple): If TREE_VALUE (VALUE) == NULL_TREE, don't
5908 call CH_COMPATIBLE or try to convert it to TREE_TYPE (FIELD). This
5909 can happen when constructors are output incrementally.
5910 * c-typeck.c (initializer_constant_valid_p): Handle SET_TYPEs.
5911 * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
5912 CONSTRUCTORS.
5914 Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5916 * ch-convert (digest_structure_tuple): Handle SET_TYPEs. Also, call
5917 `convert' so we can handle INSTANCE types (and other anomolies)
5918 correctly.
5920 * ch-convert.c (digest_structure_tuple): Fixed variant
5921 structure initialization. Also fixed a typo (TYPE_NAME
5922 was being used on a FIELD_DECL instead of DECL_NAME).
5923 * c-typeck.c (initializer_constant_valid_p): Pass missing
5924 ENDTYPE argument on recursive call.
5925 (set_init_field): New function, needed by ch-convert.c change above.
5927 * ch-decl.c (layout_chill_variants): Added a FIXME next to an
5928 almost certain typo.
5930 * ch-expr.c (build_chill_arrow_expr): Call `build1' and set
5931 TREE_CONSTANT for static references.
5932 * ch-except.c (chill_start_on): Change calls to
5933 `build_unary_op' (which is C-specific) to `build_chill_arrow_expr'
5934 which has CHILL semantics.
5935 * ch-convert.c (convert): Ditto (albeit in some disabled code).
5937 Sat Jan 1 21:26:43 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5939 * ch-satisfy.c (safe_satisfy_decl): Reorder conditional test of
5940 TREE_CODE of DECL in case it's altered by actions in the switch.
5942 * ch-satisfy.c (satisfy): Undo abort added earlier on 1 Jan. CVS log
5943 mentions where to find code that triggers this case.
5945 * ch-actions.c (adjust_parm_or_field): Handle CONSTRUCTORS here as
5946 well.
5948 * ch-convert.c (digest_structure_tuple): Push to permanent_obstack if
5949 we're dealing with a CONSTRUCTOR that is TREE_PERMANENT.
5950 (digest_constructor): Ditto.
5952 Sat Jan 1 10:29:19 1994 Michael Tiemann (tiemann@blues.cygnus.com)
5954 * ch-parse.y (handleraction,resultaction,assignaction,call): Modified
5955 so that CONSTRUCTORS are properly handled before being used.
5957 * ch-convert.c (chill_start_init): New function. All callers to
5958 `start_init' changed to call this function instead.
5959 (digest_struct_tuple): Defend against initialization machinery
5960 mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
5961 IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
5962 needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
5963 can be refered to throughout the compilation unit. Also remove an
5964 extraneous call to `process_init_element' erroneously added to the
5965 variant record sub-loop.
5966 (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
5967 CONSTRUCTORS of SET_TYPE.
5968 * ch-parse.y (build_chill_constructor): Refix typo. Also set
5969 TREE_STATIC if at top level.
5971 * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
5972 TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
5973 should have been called.
5975 * ch-convert.c (digest_struct_tuple): Restore code which tracks
5976 field initializations so that the compiler can deduce what variant
5977 initializations to assume.
5979 * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
5980 when we push into a scope that has a DECL with a CONSTRUCTOR as its
5981 DECL_INIT.
5983 * ch-parse.y (build_chill_constructor): Change the name of the
5984 parameter to something more meaningful. Fix typo. Also, handle case
5985 where element is an untyped CONSTRUCTOR.
5987 * ch-except.c (finish_handler_array): Set TREE_CONSTANT on
5988 constant ADDR_EXPRs.
5989 (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT
5990 on JBUF_REF (instead of calling `build1' which does not).
5992 * ch-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
5994 * ch-typeck.c (chill_expand_tuple): Deleted.
5995 * ch-parse.y (primval rule): Don't call `chill_expand_tuple';
5996 instead, use initialization machinery for CONSTRUCTORS that
5997 come through here.
5998 * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
5999 that are created here.
6000 * ch-satisfy (satisfy): Abort in case we would have called
6001 chill_expand_tuple. FIXME: some other code is needed here,
6002 but I don't know what yet.
6004 * ch-parse.y (build_chill_constructor): New function to
6005 propagate TREE_CONSTANT bits to CONSTRUCTORS.
6006 (untyped_expr rule): Use it.
6007 (primval rule): Use it.
6009 * ch-decl.c (do_decl): Call `finish_init'.
6010 * ch-convert.c (convert): If we spontaneously create a CONSTRUCTOR in
6011 this function, make sure the initialization machinery is set up.
6013 * ch-convert.c (digest_structure_tuple, digest_constructor): Add
6014 missing prototypes.
6016 Fri Dec 31 11:31:01 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6018 * ch-grant.c (chill_finish_module_code): Mark ADDR_EXPR built by hand
6019 as being TREE_CONSTANT. Otherwise it gets bounded by the initializer
6020 code.
6022 * ch-decl.c (do_decl): Change in CONSTRUCTOR handling due to...
6023 * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
6024 rewritten to work with GCC's initialization code. The basic change
6025 was to keep the initializers in sync with the initialization
6026 machinery that `process_init_element' imposes. Both of these
6027 functions now return `void'.
6028 * ch-convert.c (convert): Changed calls to `digest_...' functions.
6030 FIXME: the code handling UNION_TYPE (and variant records) has not
6031 been tested yet.
6033 Fri Dec 31 15:32:56 1993 Bill Cox (bill@rtl.cygnus.com)
6035 * ch-lex.l (convert_number): Output the converted number if
6036 yydebug is enabled.
6037 * ch-parse.y (signaldef): Set ignore_exprs correctly for a
6038 SIGNAL declaration.
6040 Fri Dec 31 13:17:48 1993 Bill Cox (bill@cygnus.com)
6042 * ch-parse.y: Cleanup handling of RETURN actions, to distinguish
6043 a RETURN without a value (which cannot have an exception
6044 handler) from a RETURN with a value (which can). Eliminate
6045 some shift/reduce and reduce/reduce conflicts.
6047 Thu Dec 30 17:42:32 1993 Michael Tiemann (tiemann@blues.cygnus.com)
6049 * ch-inout.c (build_chill_writetext): Deal with 2 cases where
6050 types returned from `type_for_size' are not expected. FIXME.
6051 * ch-decl.c (init_decl_processing): Mark `char_type_node' unsigned.
6052 This is required when range checking is enabled.
6054 Thu Dec 30 14:28:25 1993 Bill Cox (bill@rtl.cygnus.com)
6056 DELAY CASE works now.
6057 * ch-decl.c (init_decl_processing): Move rest of tasking-related
6058 initialization into tasking_init().
6059 * ch-parse.y (delaycaseaction): Pervasive additions/corrections.
6060 (optsetprio): New non-terminal.
6061 * ch-tasking.c (get_task_name): Delete, obsolete.

6063 (build_receive_case_start): Cleanup per -Wall messages.
6064 (build_receive_case_label): Move between start and end functions.
6065 (build_delay_case_start): Pass SET name and priority also.
6066 Generally update to correct functioning.
6067 (build_delay_case_label): Move between start and end fucntions,
6068 correct its functioning.
6069 (build_delay_case_end): Correct the code.
6070 (tasking_init): Lots of tasking-related code moved here from
6071 init_decl_processing.
6072 * ch-tree.h: Update, add prototypes.
6074 Wed Dec 29 10:13:10 1993 Bill Cox (bill@rtl.cygnus.com)
6076 * ch-expr.c (build_chill_indirect_ref): Revert change which
6077 failed full regression testing.
6078 * ch-lex.l (name_type_signal): Add debug output.
6079 * ch-parse.y (structured_variable): Add a debug variable.
6081 Wed Dec 29 02:05:51 1993 Bill Cox (bill@rtl.cygnus.com)
6083 * ch-decl.c (get_next_decl): Revert change which failed full
6084 regression testing.
6086 Tue Dec 28 18:20:14 1993 Bill Cox (bill@rtl.cygnus.com)
6088 DELAY actions work now.
6089 * ch-decl.c: Correct spelling in comments.
6090 (get_next_decl): NULL out the decl's TREE_CHAIN before returning
6091 it, to prevent accidental access to the remembered_decls.
6092 (init_decl_processing): Add wait_event to runtime functions.
6093 * ch-expr.c (build_chill_indirect_ref): Prevent a syntax error from
6094 becoming a seg fault.
6095 * ch-grant.c: Correct a comment.
6096 * ch-loop.c: Delete/correct comments.
6097 * ch-parse.y (delaycaseaction): Add push/poplevel calls. Turn 'sorry'
6098 into rough draft of actual code.
6099 (delayaction): Don't make a new scope here, use get_unique_identifier
6100 instead.
6101 (locdec): process event decls here, too.
6102 (mode): Add code to forbid READonly EVENT and BUFFER decls. Delete
6103 code which required EVENTs and BUFFERs to be declared at global scope.
6104 (simple_name_string): Add an EVENTNAME.
6105 * ch-satisfy.c (safe_satisfy_decl): Prevent a syntax error from
6106 becoming a seg fault.

6121 options. Delete C-specific defines. Disable piping from
6122 pre-processor to cc1chill (even if -pipe is specified), since cc1chill
6123 rewinds its input for its second pass. Piping still works
6124 from cc1chill to as.
6126 Thu Dec 23 12:31:55 1993 Bill Cox (bill@rtl.cygnus.com)
6128 * ch-tasking.c (decl_tasking_code_variable): Assure that the

6132 Other changes to variable names to increase 'self-documentation'
6133 the only kind GNU CHILL will get, for a while..
6135 Wed Dec 22 10:46:31 1993 Bill Cox (bill@rtl.cygnus.com)
6137 * ch-decl.c (do_seize): Delete - it's unused. Fix comments.
6138 * ch-loop.c (build_chill_iterator): Convert BY expression

6140 for numbered SET expression as start or end expression.
6141 * ch-tree.h: Prototypes for future DELAY functions.
6142 * ch-typeck.c: Standard indentation.
6144 Tue Dec 21 15:30:57 1993 Per Bothner (bothner@kalessin.cygnus.com)

6161 * ch-tree.h (CH_EQUIVALENT): Re-defined to use chill_equivalent.
6163 * dbxout.c (dbxout_type): Output the type attribute "@S;" to
6164 distinguish a string from a char array, and to distinguish a
6165 bitstring from regulat (power)set. (Needed for Chill.)
6166 * dbxout.c (dbxout_type): Only check for baseclasses in
6167 type.binfo is a vector. (It is used in Chill for tagged unions.)
6169 Fri Dec 17 09:56:07 1993 Bill Cox (bill@rtl.cygnus.com)
6171 * ch-actions.c, ch-convert.c, ch-decl.c, ch-expr.c,

6189 * ch-tree.h: Fix prototypes.
6190 * ch-typeck.c (smash_dummy_type): Handle all four kinds of LANG_TYPE

6205 Tue Dec 14 15:41:32 1993 Per Bothner (bothner@kalessin.cygnus.com)
6207 * ch-decl.c (push_scope_decls): Re-arrange so that normal
6208 (non-seize) declarations are proclaim_decl'd *before* we
6209 handle the ALIAS_DECLs for seizes. The advantage is
6210 that we can now test for (an approximation) to the
6211 'seizeable' concept, thus avoiding duplicate definitions
6212 when a module has both GRANTs and SEIZE ALL.
6214 * ch-expr.c (build_chill_arrow_expr): No longer re-write
6215 addr-of-conversion to pointer-conversion-of-addr.

6223 * ch-tree.h (chill_root_resulting_mode): Fix typo (missing '_').
6225 * ch-expr.c (finish_chill_binary_op): Use CH_ROOT_RESULTING_MODE
6226 macro (which works on expressions), rather than CH_RESULTING_MODE
6227 (which works on modes, and isn't quite correct).
6228 * ch-tree.h (CH_IS_BOUND_REFERENCE_MODE): New macro.
6229 * ch-typeck.c (chill_read_compatible, chill_compatible):
6230 Use the new macro, which handles NEWMODEs of PTR correctly.

6232 dynamic-length array (and string) types (e.g. slices).
6233 * ch-typeck.c (chill_root_mode): If the mode has a Novelty,
6234 just return it as is. (This is still not 100% correct for
6235 NEWMODE of RANGEs, but is close enough.)
6237 Mon Dec 13 16:27:06 1993 Bill Cox (bill@rtl.cygnus.com)
6239 * ch-parse.y (locdec): Avoid passing IDENTIFIER_NODEs to

6275 for bitstring constants.
6276 * ch-typeck.c (chill_novelty): The novelty of an (unnamed)
6277 range mode is that of its parent mode; the novelty of READ M
6278 is that of M.

6283 rather than save_expr.
6284 * ch-typeck.c (build_chill_slice): Don't emit warning
6285 if array is a SAVE_EXPR (it is effectively referable).
6286 * ch-typeck.c (chill_root_resulting_mode): Handle
6287 correctly the case that one operand is DERIVED and one is VALUE.

6354 of set elements of similar set modes.
6356 * ch-parse.y (caseaction): Call language-independent

6970 easier non-symbol-table access later.
6971 * ch-tasking.c (generate_tasking_code_variable): Do work in both
6972 passes, using do_decl so we can pass the pass 2 value of the
6973 process_type or signal_code to it. Only update the process_type
6974 if the incoming pointer isn't null and pass == 2. Use a new
6975 parameter to know whether to include an init expression.
6976 (build_process_header): Attach tasking-code_variable to process
6977 function_decl for easy access later, not through the hash table.

6992 generation for decls to not use DECL_ASSEMBLER_NAME.
6993 * ch-decl.c: Set DECL_ASSEMBLER_NAME to DECL_NAME.
6994 This matches C, and allows dbxout to emit proper user-level names.
6995 (It would be cleaner to fix dbxout to use DECL_NAME ...)
6996 * ch-decl.c (outer_decls): New global list of the decls granted
6997 into the outer scope.
6998 (pop_module): Change code that grants into outer scope accordingly.

7013 * ch-tree.h: Restore old version.
7014 * ch-expr.c (finish_chill_binary_op): Convert TRUNC_DIV_EXPR
7015 to RDIV_EXPR if an operand is floating. (This functionality

7019 not error_mark_node.
7020 * ch-actions.c (chill_expand_assignment): Allow such borderline
7021 constructs as: LHS OR:= [X].
7022 * ch-convert.c (convert): Hande CASE_EXPR (and COND_EXPR)

7025 * ch-typeck.c (chill_compatible): Allow expr to have NULL mode
7026 if it's a CASE_EXPR or COND_EXPR (and not just CONSTRUCTOR).

7037 * ch-grant.c (chill_finish_module_code): Put module's decl onto
7038 the module_init_list, for chill_finish_compile's possible use.
7039 (chill_finish_compile): Rename variables for clarity, add
7040 commented-out code as example for assignment of module address to its
7041 init_list entry.
7043 Sun Oct 17 15:16:54 1993 Bill Cox (bill@cygnus.com)
7045 * ch-convert.c: Move semicolon to separate line - easier to see.
7046 * ch-decl.c (do_decl): Handle untyped_expr initializers by
7047 simply using the variable's declared type - no compatibility
7048 check can be made if the expression has no type.
7049 * ch-expr.c (expand_packed_set): Fix endless loop - increment
7050 the loop variable.
7051 (fold_set_expr): Fix two other endless loops by passing
7052 correct parameters to unpack_set_constructor.

7307 * ch-convert.c (convert_to_reference): Check for loc-identity
7308 mismatches correctly (and remove one of those chill_compatible
7309 calls).
7310 * ch-decl.c (decl_tasking_code_var): New function, called from
7311 push_extern_process and push_extern_signal.
7312 * ch-parse.y (end_function): Delete parameter. Check current_function_decl
7313 whether it's actually a process, and whether it has parameters.
7314 Make Michael's change simplifying the pass 2 test, preventing a seg
7315 fault.
7316 (procedure, process): Change calls to end_function, remove
7317 code saving value from build_process_header. Delete redundant chill_
7318 phrases from some function calls.

7341 * ch-expr.c (build_chill_function_call): Use CH_LOCATION_P
7342 to check for location, rather than TYPE_CODE_CLASS == 'd'.

7394 Sat Sep 25 13:54:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
7396 * ch-decl.c: Expand pre-amble comment.
7397 * ch-decl.c (struct scope, push_module): Use new field
7398 tail_chain_module to build child-module list in order.
7399 (Just to make compiler debugging a little less confusing.)
7401 * ch-decl.c (struct scope): New field weak_decls.
7402 * ch-decl.c (find_implied_types): New interface. Now pre-pend
7403 new enum types to a given input list. This makes it easier to
7404 avoid duplicates, which should at least be more efficient.
7405 Also, handle FUNCTION_DECL.
7406 * ch-decl.c (bind_saved_names): Removed. Distribute its
7407 functionality over new functions (push_scope_decls, pop_scope_decls,
7408 build_implied_names, bind_sub_modules). The goal (which seems to
7409 have been more-or-less attained) was to fix weak name handling.
7410 * ch-decl.c (poplevel): Use new function pop_scope_decls.
7412 * ch-tasking.c (build_signal_struct, build_tasking_message_type):
7413 Use build_decl directly, rather than grok_chill_fixedfields
7414 (which depends on ignore_exprs and has more overhead).
7415 * ch-tasking.c (build_signal_struct): Construct the type
7416 only in pass 1.
7417 * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
7418 than build_array_ref (which does C-specific "optimizations").
7419 (Hence move my_build_array_ref up earlier in the file.)
7421 Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7423 * ch-tasking.c: Declare static variable `void_ftype_void'.
7424 (chill_tasking_init): Initialize `void_ftype_void' here.
7425 (build_tasking_struct): Use, don't declare `void_ftype_void'.
7426 (generate_tasking_code_variable): Call `do_decl', not
7427 `decl_temp1' to declare TASKING_CODE_NAME.
7428 (tasking_setup): Drop into 1-pass mode so that all
7429 tasking-related declarations are installed in the global
7430 scope. Use correct CHILL types for initializers (since
7431 ptr_type_node doesn't have the right meaning for CHILL).
7432 Also, call `do_decl' instead of `decl_temp1' for
7433 `init_struct'.
7434 (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
7435 `chill_finish_compile' in sync between passes.
7437 * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
7438 declarations on pass zero. Keep obstacks in sync, and always
7439 call `finish_decl' for pass zero declarations.
7440 (push_chill_extern_function): Keep obstacks in sync, and always
7441 call `finish_decl' for pass zero declarations.
7442 (build_enumerator): Ditto.
7443 (grok_chill_variantdefs): Change PASS test to exclude only
7444 pass one.
7445 (finish_struct): Ditto.
7446 * ch-expr.c (build_chill_component_ref): Ditto.
7447 (build_chill_binary_op): Ditto.
7448 * ch-tree.c (build_powerset_type): Ditto.
7449 (build_bitstring_type): Ditto.
7450 * ch-typeck.c (build_chill_range_type): Ditto.
7451 (build_chill_struct_type): Ditto.
7453 * ch-decl.c (build_chill_exception_decl): Clarify reasons for
7454 extra pushing and popping of obstacks.
7456 * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
7457 on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
7459 * ch-grant.c (chill_finish_compile): Clear out both
7460 MODULE_INIT_LIST and TASKING_LIST if either contains stuff
7461 from pass one.
7463 * ch-parse.y (rccase_label): Add NAME rules so that pass one
7464 works w/o knowing we're parsing a signal. Simplify SIGNALNAME
7465 rules since we only get SIGNALNAME tokens in pass two.
7466 (sendaction): Ditto.
7467 * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
7468 BUFFERNAME on pass two. The grammar now handles this.
7469 * ch-decl.c (lookup_remembered_decl): Deleted.
7471 Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
7473 * ch-decl.c (lookup_remembered_names): Removed. It was being
7474 misused in ch-lex.l.
7475 * ch-lex.l (name_type_signal): Revert last change. Basically,
7476 we cannot use the C typedef/variable name trick in CHILL, due
7477 due to the language's 2-pass nature.
7478 * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
7479 a seg fault.
7480 * ch-tree.h (lookup_remembered_name): Comment out the prototype.
7482 Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7484 * ch-decl.c (do_decl, push_chill_extern_function): Change pass
7485 checks so the pass == 0 case is handled for built-in types.
7486 (push_modedef): Add check for error_mark_node.
7487 (lookup_remembered_decl): New function.
7488 (pushlevel, poplevel) Change pass checks.
7489 (pushdecl): Check type as well for NULL.
7490 (build_enumerator): Handle pass == 0 case.
7491 * ch-lex.l: Use lookup_remembered_decl to get lastiddecl
7492 during pass 1.
7493 * ch-parse.y: Set pass to zero to indicate initial decl processing.
7494 Replace NAME references with SIGNALNAME references.
7495 (startaction): Only check copy number if not ignoring actions.
7496 Always call build_chill_start_process.
7497 (optstartset): Don't lookup the instance name.
7498 * ch-tasking.c (generate_tasking_code_variable): Replace
7499 do_decl call with decl_temp1 call.
7500 (build_chill_start_action): Check for ignore_actions here.
7501 (build_tasking_message_type): Layout the type.
7502 (rc_state_type): New structure to keep nested receive-case
7503 info in.
7504 (build_chill_receive_case_start, build_chill_receive_case_end):
7505 Use the new struct.
7508 Fri Sep 24 04:19:15 1993 Michael Tiemann (tiemann@blues.cygnus.com)
7510 * ch-tasking.c (build_chill_receive_case_start): `namedecl'
7511 should be a _DECL, not an IDENTIFIER_NODE.
7513 Thu Sep 23 18:18:24 1993 Per Bothner (bothner@kalessin.cygnus.com)
7515 * ch-decl.c (find_implied_types): Handle VAR_DECLs.
7517 * ch-decl.c (print_lang_identifier): Print IDENTIFIER_OUTER_VALUE.
7518 * ch-actions.c (chill_expand_result): Allow value-less RETURN.
7519 * ch-expr.c (resolve_component_ref): Recognize error_mark.
7521 * ch-convert.c (digest_constructor): Handle a nested powerset tuple.
7522 * ch-satisfy.c (satisfy): Use return value of layout_chill_range_type.
7523 * ch-typeck.c (chill_similar): Repeatedly get parent modes
7524 of ranges, not just once.
7525 * ch-typeck.c (chill_root_resulting_mode), ch-tree.h: New function.
7526 * ch-typeck.c (layout_chill_rang_type): Re-do type-checking
7527 to follow Blue Book better (check for Compatibility).
7529 * ch-tree.h (CH_ROOT_RESULTING_MODE): New macro.
7530 * ch-lex.l (use_seizefile_name, current_seizefile_name), ch-tree.h:
7531 New variables. The latter replaces in_seizefile.
7533 Changes to store in the new DECL_SEIZEFILE field each seize
7534 ALIAS_DECL the name in the most recent use_seize_file directive.
7535 (This requires that use_seize_file directives written to the
7536 grant file be written before the SEIZEs that need it.)
7537 Allow clashing declarations granted into the global scope
7538 (produce a warning), but remember the seizefile case from
7539 (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
7540 The a SEIZE will select the granted decl that matches its
7541 DECL_SEIZEFILE (in other words: grants from the most recent
7542 use_seize_file will be preferred).
7543 * ch-tree.h (DECL_SEIZEFILE), ch-tree.def: New macro.
7544 * ch-tree.h (global_value, IDENTIFIER_GLOBAL_VALUE): Renamed
7545 to outer_value, IDENTIFIER_OUTER_VALUE.
7546 Changes to cause the use_seize_file directives to be written
7547 out in order as they're seen in source.
7548 * ch-lex.l (files_to_seize, next_file_to_seize, last_file_to_seize):
7549 Changed to have type TREE_LIST of pointer to IDENTIFIER_NODE.
7550 * ch-lex.l (handle_use_seizefile_directive): Modify appropriately.
7551 Don't call grant_use_seizefile.
7552 * ch-lex.l (mark_use_seizefile_written): New function.
7553 * ch-grant.c (decode_decl): Write out use_seize_file directive,
7554 if needed, before writing a seize declarations.
7555 * ch-decl.c (pop_module): Handle decls granted into the global
7556 module specially, setting IDENTIFIER_OUTER_VALUE.
7557 * ch-decl.c (lookup_name_for_seizing): Check IDENTIFIER_OUTER_VALUE.
7559 Thu Sep 23 19:05:37 1993 Bill Cox (bill@cygnus.com)
7561 * ch-decl.c (push_chill_extern_process): Delete unused variables,
7562 declare the process' tasking_code variable as external.
7563 * ch-parse.y (process): Force ignore_exprs to FALSE while parsing
7564 the process header.
7565 * ch-tasking.c (sigdef): Move resetting of quasi_signal from here
7566 to (signaldef).
7567 * ch-tree.h: Add prototype.
7568 * expr.c (store_constructor): Emergency first-aid. Rewrite later.
7570 Thu Sep 23 12:57:53 1993 Per Bothner (bothner@kalessin.cygnus.com)
7572 * ch-expr.c (build_chill_function_call): Move possible call to
7573 chill_start_module_code until we know we're not calling a builtin.
7574 * ch-decl.c (save_expr_under_name): Use pushdecllist,
7575 not proclaim_decl (which provide for popping the decl).
7576 * ch-parse.y (optname): Also allow TYPENAME.
7578 Thu Sep 23 09:18:35 1993 Bill Cox (bill@cygnus.com)
7580 * ch-decl.c (print_lang_decl): Make weak name output more standard.
7581 (print_lang_identifier): Make signal-data flag output more standard.
7582 (push_chill_extern_process): Pass correct arg tree to
7583 push_chill_extern_function.
7584 (push_syn_decls, fixup_unknown_type, chill_modes_equiv):
7585 Standardize function header layouts (Makes the tcov script
7586 work better).
7587 * ch-except.c (chill_finish_on): Standardize function header.
7588 * ch-expr.c (fold_set_or): Standardize function header.
7589 * ch-grant.c (print_proc_tail, print_proc_exceptions): Standardize

7605 inside the proper loop.
7606 * ch-grant.c (print_struct): Add missing loop for tag_list.
7607 (print_struct): Look for variant fields by checking for a
7608 UNION_TYPE, not a NULL name, since we must use a dummy name.
7609 * ch-parse.y (structured_variable): Various fixing.
7610 * ch-decl.c (shadow_record_fields): Rename arg decl -> struct_val.
7612 * ch-satisfy.c (safe_satisfy_decl): Disable copying of modes
7613 for NEWMODE (and hence novelty checking), until we figure out
7614 a better way.
7616 * ch-except.c (finish_handler_array): Use null_pointer_node,
7617 not integer_zero_node (which fails to type-check).

7621 (CH_NOVELTY): Redefined to call new function chill_novelty.
7622 (CH_CLASS_IS_XXX, TYPE_NEWMODE, CH_CLASS_MODE): Removed.
7623 * ch-typeck.c (classify_chill_expr renamed to chill_expr_class):
7624 Take extra output parameter (for M, as in M-value class).
7625 * ch-typeck.c (chill_novelty): New function. (Also de-references.)
7627 * ch-expr.c (resolve_component_ref, build_chill_component_ref):
7628 New functions. Handle 2-pass and variant records.
7629 * ch-parse.y (primval DOT name): Use instead of build_component_ref.
7630 * ch-satisfy.c (satisfy, case COMPONENT_REF):
7631 New case, call resolve_component_ref.
7633 * ch-expr.c (build_generalized_call): Extract single arg from
7634 arg list before calling build_chill_cast.
7636 * ch-parse.y (defining_occurrence_list): New non-terminal.
7637 Use it to replace locnamelist, synnames, and modenames.
7638 * ch-parse.y: Re-write parsing of variant records.
7640 * ch-decl.c (grok_chill_variantdefs): Now return a FIELD_DECL
7641 rather than just its type.
7642 * ch-inout.c (build_chill_io_list_type), ch-parse.y:

7650 * ch-convert.c (remove_tree_element, digest_structure_tuple):
7651 New functions, to digest structure tuples, without calling the

7674 (quasi_locdec): Call build_chill_reference_type to defer
7675 doing the type's layout.
7676 (processpar): Use paramnamelist, but reformat it into a
7677 list of identifiers in pass 2, so a processpar is the same
7678 structure in both passes.
7679 (locdec): Call build_chill_reference_type to defer doing the
7680 type's layout.
7681 * ch-tasking.c (generate_tasking_code_variable): Call do_decl to
7682 build the decl. Only update the variable's tree in pass 2.
7683 (make_process_struct): Call build_chill_reference_type to defer
7684 doing the type's layout.
7685 (build_process_header): New code to call make_process_struct.
7686 New pass-2 code to make a PARM_DECL for start_chill_function.
7687 Pass a void_type_node, not a NULL_TREE for an empty list.
7688 Get input for shadow_record_fields from current_function_decl.
7689 (build_buffer_decl): Call do_decl not decl_temp1.
7690 * ch-typeck.c: Reindent to standards.
7691 * gcc.c (SPECS): Add recognition for the '.chi' CHILL suffix.

7695 * ch-typeck.c (classify_chill_expr): An expression with a
7696 REFERENCE_TYPE still has VALUE class, even if an ADDR_EXPR.
7697 * ch-actions.c (adjust_parm_or_field):, ch-tree.h: Change last
7698 parameter, so we can reliably recognize LOC parameters.
7699 * ch-tasking.c, ch-expr.c: Change callers appropriately.

7722 Fri Sep 10 12:23:41 1993 Wilfried Moser (fs_moser@cygnus.com)
7724 * Makefile.in: Change installation of the chill script. gcc will
7725 be called always with the full path. That made problems when

7727 directory in PATH.
7728 * ch-parse.y: Change parsing of WRITETEXT action.
7729 * ch-tree.h: Add some new prototypes according to the

7740 chill_stderr.
7742 Fri Sep 17 22:02:04 1993 Per Bothner (bothner@kalessin.cygnus.com)
7744 * ch-decl.c (push_modedef): Fix TYPE_MAIN_VARIANT thinko.

7788 Mon Sep 13 17:33:11 1993 Per Bothner (bothner@kalessin.cygnus.com)
7790 * ch-grant.c (lookup_decl_in_process, register_decl_as_output,
7791 decl_seen_p, processed_decls, allocated, nr_decls): Removed
7792 no-longer-useful functions and variables that used to guard
7793 against writing a decl multiple times. Since we now just
7794 go through the decl list linearly, that is no longer an issue.
7795 * ch-satisfy.c (safe_satisfy_decl): Handle missing current_module.
7797 * ch-decl.c (start_chill_function): Clear DECL_ASSEMBLER_NAME.

7803 * ch-tree.h (struct module): New field prefix_name.
7804 * ch-satisfy.c (safe_satisfy_decl): If assembler_name isn't
7805 set, prefix it by the module name(s).
7806 * ch-satisfy.c (safe_satisfy_decl, case FUNCTION_DECL):
7807 Call make_function_rtl if needed and !LOOKUP_ONLY.
7808 * ch-typeck.c (chill_similar): Flesh out substantially.
7809 * ch-typeck.c (chill_compatible): Re-structure.
7811 * ch-actions.c (adjust_parm_or_field): Use CH_COMPATIBLE

7835 for shadow_record_fields. Move debug_scope before
7836 its first call.

7838 pass 2.
7839 * ch-grant.c (print_proc_tail): Avoid trying to format

8341 * ch-parse.y (build_prefix_clause): New function (handle PREFIXED).
8342 * ch-parse.y (optprogendname, optname): Rename to opt_end_label.
8343 * ch-parse.y: Add support for compound name strings, but defer

8645 * ch-decl.c: See Generally.
8646 (init_decl_processing): Call build_tasking_enum from here.
8647 Now, it doesn't need a flag to do its work only once.
8648 Also, build the TaskingStruct decl here.
8649 * ch-grant.c: Remove references to `current_grant_file';
8650 there's now only one. See Generally. Do gcc -Wall cleanup.
8651 * ch-lex.l: Remove references to `current_grant_file'
8652 and delete USE_GRANT_FILE token.
8653 * ch-parse.y: Remove call to build_tasking_enum, and its extern.

8669 (chill_finish_module_code): Use global_bindings_p to determine
8670 'nested' parameter for finish_chill_function. Use new
8671 module_has_actions flag to trigger generation of module_init list
8672 entry. We now can handle not only multiple modules per file,
8673 but modules nested inside functions (I think).
8674 * ch-lang.c (build_chill_pointer_type): Restore missing assignment.

8703 * ch-lang.c: Move pass-1 stuff from build_chill_pointer_type
8704 into new function make_chill_pointer_type, and split
8705 build_chill_struct_type into make_chill_struct_type
8706 and layout_chill_struct_type.
8707 * ch-decl.c (grok_chill_variantdefs): Similarly split up
8708 into make_chill_variants and layout_chill_variants.

8714 Fixup previous check-in.
8715 * ch-decl.c: Restore unnamed_module_number, which *was*
8716 used after all.
8717 * ch-grant.c (get_init_function_id): Return type s.b. tree.

8738 (chill_finish_module_code): Add module name parameter.
8739 * ch-typeck.c: Fix comments, add whitespace.
8741 Fri Aug 6 12:17:07 1993 Per Bothner (bothner@kalessin.cygnus.com)
8743 * ch-decl.c (temp_pushdecl, bind_saved_names): The simple-minded
8744 way I allocated the shadow_list on an obstack was too fragile,
8745 so just use xmalloc/free instead.

8749 * ch-satisfy.c (satisfy): Satisfy TYPE_MIN_VALUE and

8791 * ch-decl.c (init_decl_processing): Only build types
8792 in pass 2, since dbxout machinery is only ready for
8793 output then.
8794 * ch-grant.c (chill_finish_module_code): Do most of the
8795 work in pass 2.
8797 Thu Aug 5 06:54:10 1993 Bill Cox (bill@rtl.cygnus.com)

8922 header. Use #undef to assure that strchr isn't a
8923 macro (portability), and remove the extra paren-
8924 theses in its extern name.
8925 (check_newline): Call getlc less often, so that user
8926 labels aren't lowercased before their time. Add BEGIN
8927 INITIAL before starting pass 2, so the header is
8928 correctly ignored.

9051 on each pass. Hence, can use code in c-decl.c to lesser extent.
9052 * ch-decl.c (build_chill_function_type): First arg is now
9053 just the return type, rather than a singleton list.
9054 * ch-decl.c (massage_param_node): Remove not needed (we
9055 now encode parameter attributes directly in the TREE_PURPOSE).

10007 expression, so we can output it.
10008 * ch-lang.c (deep_const_expr): New function, called

10090 bit_size, since 'size' always means bytes.
10091 (pack_set_constructor): Rename size to wd_size,
10092 since 'size' always means bytes.
10093 (output_constant): Set size to zero, so that extra

10153 function is no longer visible,, can't get it using
10154 lookup_name(). Use current_function_decl instead.
10156 * ch-decl.c (build_chill_function_type): Add void_type_node
10157 to end of parameter types list.
10159 * ch-grant.c (chill_start_module_code): Make sure module
10160 function isn't visible (and hence isn't granted).

10164 * ch-loop.c (begin_chill_loop): Also stamp the user's loop name into

10199 (modedefinition): Use new push_modedef function.
10200 * ch-parse.y (modedefinition): Don't depend on inherited

10230 (start state 'ccitt'): Deleted, unused. Moved unused, but reserved,
10231 tokens to NORMAL state.
10232 (compiler_directive): Replaced by equal_number. Now the only
10233 recursive call to yylex happens in check_newline at the beginning
10234 of a compilation.
10236 Sat Apr 10 09:55:50 1993 Bill Cox (bill@rtl.cygnus.com)
10238 * ch-actions.c (build_chill_case_expr): Added from ch-parse.y.
10239 * ch-lex.l (ENTRY, PERVASIVE, ROW, STEP): Add token recognition to
10240 'reserve' them.
10241 * ch-parse.y (case_expr): Move code into ch-actions.c. There will
10242 need to be much more written.
10243 * ch-tree.def (VARY_ARRAY_REF): Add comment.
10244 * ch-tree.h (build_chill_case_expr): Add prototype.
10245 * ch-typeck.c (build_chill_cast): Allow untyped_expr - just assign the

10248 Sat Apr 10 01:10:51 1993 Per Bothner (bothner@rtl.cygnus.com)
10250 * ch-parse,y (in_pseudo_module): New variable. Try if we're
10251 in a seizefile, but not in a module nested in the seizefile.
10252 Use for backwards compatibility with old grantfiles.
10253 * ch-decl.c (do_decls, push_syndecls, push_newmode, push_synmode):

10264 * ch-lex.l: Re-write to use start states, to avoid calling
10265 yylex() recursively.
10266 * ch-lex.l (compiler_directive); This is now obsolste. FIXME.
10267 * ch-lex.l: Call push_module and pop_module when reading a
10268 seizefile. This creates a pseudo-module.
10269 * ch-parse.y: Clean up handling of empty declarations and
10270 action statements; semicolons are now optional a number of
10271 places.
10272 * ch-parse.y: Remove some bogus tests for "statement
10273 out of sequence" (they're both legal and work).
10274 * varasm.c (mak_function_rtl): Remove kludge that may
10275 not be necessary (and loses anyway).
10277 Fri Apr 9 09:37:38 1993 Bill Cox (bill@rtl.cygnus.com)
10279 * ch-expr.c (chill_expand_array_assignment): Remove false error about

10295 * ch-grant.c (chill_grant), ch-tree.h: Add a parameter
10296 which is the list (in order) of decls in the module.

10298 * ch-grant.c (chill_grant): Test that a declaration is
10299 visible before writing it.
10300 * ch-parse.y (push_module): Make sure to hide declarations

10315 assignment, clean up.
10316 * ch-typeck.c: Add prototype for require_complete_type.

10326 * ch-decl.c (massage_param_node): New function.
10327 It handles the LOC/IN/OUT/INOUT parameter distinction,
10328 as well as calling build_chill_array_parm_type if needed.
10329 * ch-tree.h (massage_param_node): New prototype.
10330 * ch-decl.c (push_parms): Use new massage_param_node().

10335 lower bounds.
10336 * ch-actions.c (build_chill_function_call): If the formal

10340 the pseudo struct type is allocated on the permanent_obstack.
10341 * ch-parse.y (location): Remove thinko.
10342 * ch-actions.c (chill_comptypes): Comment out test for

10366 build_array_ref. Change checks, error messages to mention
10367 'discrete types'. I.E. types which don't kiss and tell..

10377 Fri Apr 2 21:55:14 1993 Per Bothner (bothner@rtl.cygnus.com)
10379 Major re-write of New module/seize/grant stuff.
10380 Now, a grantfile is a spec module and contains all the
10381 top-level declarations of the granting module, not just
10382 those that are granted. It also contains explicit grant
10383 statments naming those declared names that are granted.
10384 It also has seize statements and use_seize_file directives
10385 to correctly handle transitive dependencies.
10387 * ch-parse.y: Change to allow multiple modules per source file.
10388 Allow spec modules (including quasi definitions) as well as
10389 regular modules.
10390 Allow spec modules inside normal modules; these behave as if
10391 they were outermost. This violates the Blue Book, but is
10392 needed by the new grantfile mechanism. (A grant file is a
10393 spec module that gets included by the use_seize_file directive.)
10394 * ch-parse.y (struct module *current_module, push_module,
10395 pop_module): Support module nesting (for spec modules only).
10397 * ch-tree.h (struct module): New.
10398 * ch-grant.c (granted_decls): New list of declarations
10399 that have been granted into the outermode pseudo-module.
10400 * ch-grant.c (decode_mode): If the decl has a name,
10401 always write the name, not just if the decl has already
10402 been written. Since we write out all decls, we can assume
10403 it will be written later, and depend on the forward
10404 declaration kludges to catch it.
10405 * ch-grant.c (decode_decl): Don't write out _EXTERN.
10406 Instead write out standard (Blue Book) quasi-definitions.
10407 * ch-grant.c (push_granted): New function.
10408 * ch-grant.c (seize_implied_names): New function. Re-write
10409 how set element names are seized when a set type is seized.
10410 * ch-grant.c (chill_seize): Work by seraching the
10411 granted_decls list and copying the declaration.
10412 * ch-grant.c (chill_grant): Write all declarations

10448 * ch-actions.c (lang_init, build_allocate_memory_call,
10449 build_allocate_globals_memory_call): Fix names (add initial '_')
10450 and prototypes of _allocate_[global_]memory (2nd param is ref).
10451 Use build_chill_function_call, not build_function_call,

10517 (variantfields, varianthack): Clean up.
10518 (variantfield): Check for IDENTIFIER_NODE, lookup its DECL if

10546 chill_expand_array_assignment can do a better job of
10547 code-generation.
10548 * ch-expr.c (chill_expand_array_assignment): Generate the CONCAT_EXPR
10549 code.

10554 array and its type get on the permanent obstack.
10555 * ch-grant.c (write_grant_file): Don't write the _INIT=name

10559 * ch-lang.c (finish_chill_enum): Don't allocate a dummy
10560 TYPE_DECL for the enum. I don't think it is needed (?),
10561 and removing it is needed for the change above.
10563 * ch-grant.c (grant_array_type, decode_mode): Remove unused
10564 'decl' parameter.
10565 * ch-grant.ch (raw_decode_mode): New function, based on old

10569 type is named and has already been emitted.
10571 Fri Mar 19 11:55:35 1993 Bill Cox (bill@rtl.cygnus.com)
10573 * ch-actions.c: Add prototypes, remove unused variables. Attempt to
10574 continue generating grant file in presence of error (Wilfried's
10575 patch to lang_finish).

10577 after each statement. Move convert call into
10578 chill_expand_assignment from ch-parse.y.
10579 * ch-grant.c: Generally re-order, clean up. Include Per's decode_mode
10580 simplification. Include commented-out hack in decode_mode to return

10597 * ch-parse.y (structured_variable): Return NULL_TREE is invalid WITH
10598 parameter is seen, don't count it in structured_variable_list. Pre-
10599 vents seg fault when only WITH operand is invalid.
10600 * ch-parse.y (label_spec): Correct assignment within IF expression which
10601 was intended to be equality test. Remove unused variables.
10602 * ch-tree.h: Add prototype. Remove unused EXCP_CODE enumeration, and
10603 prototyping editorial comments.
10604 * ch-typeck.c: Disable generation of code to validate array index for
10605 now. Should be done as a call-back from more generic array_ref code.
10606 Clean up parameter checking. Remove unused variables.
10608 Fri Mar 12 11:57:32 1993 Bill Cox (bill@rtl.cygnus.com)

10738 * ch-actions.c: Change all builtin functions names to their
10739 actual library names. Change references to boolean_type_node
10740 to references to the TREE_CODE == BOOLEAN_TYPE, to follow the
10741 convention.
10742 build_set_expr: Remove length parameter, call powersetlen() instead.
10743 remove handling of CHAR arrays - they're handled in build_char_array_expr.
10744 Call __eqpowerset to test for equality - we can't use a byte-length -
10745 need bitcount instead.
10746 build_chill_compound_expr, internal_build_compound_expr: Copy from C
10747 version that does stuff we don't want.
10748 build_binary_op: Check for in_size_in_bytes return < 0, indicating

10752 build_chill_card: Call powersetlen.
10753 build_chill_max_min: Common code for powerset max/min.
10754 build_chill_length: Move VARYING array handling before regular char
10755 array handling.
10756 * ch-expr.c chill_expand_expr: Disable concatenate code - we need to
10757 the VARYING status of the target to do this correctly. Use powersetlen
10758 for the powerset operations, not a byte length.
10759 * ch-loop.c: Make CREATE_SCOPE #define to enable creation of a new scope
10760 for each CHILL loop, as Z.200 requires. Add powerset and error flags
10761 to loop structure. Evaluate user's powerset expression into a temp,
10762 scan it destructively with __ffsetclrpowerset or __flsetclrpowerset
10763 for powerset loop. Only do loop-end assignments if NOT a powerset
10764 loop, which has much less overhead now.
10765 * ch-tree.h: Add prototype for powersetlen.

10778 we are going to return 0.
10780 * ch-convert.c (convert_to_reference): Don't use
10781 TYPE_MAIN_VARIANT, because REFTYPE's type may be a newmode
10782 (which must match the type of the expr).
10784 * ch-grant.c (chill_seize): Don't let a type be copied just
10785 because we are seizing it.
10787 * ch-lang.c (finish_chill_enum): Convert TYPE_MIN_VALUE and
10788 TYPE_MAX_VALUE to integer type.
10790 * ch-loop.c (begin_for_range): Set lp->iter_type based on the
10791 tree type of the bounds.
10792 (build_loop_top): type of GE_EXPR and LE_EXPR is
10793 boolean_type_node, not lp->iter_type.
10794 (for_location): Ditto.
10796 * ch-action.c (build_chill_lower,build_chill_upper): Handle
10797 ENUMERAL_TYPE. Also, handle different kinds of arguments more
10798 cleanly.

10801 match the type of modename.
10803 * ch-grant.c (chill_seize_aggr): Search also through anonymous

10807 already been seized, and if so, do nothing.
10809 * c-typeck.c (process_init_constructor): If DEFAULT_VALUE
10810 comes out error_mark_node, set ERRONEOUS.
10812 * ch-actions.c (build_chill_binary_op_1): If EXP is NULL_TREE,
10813 don't use it.
10815 * ch-action.c (chill_comptypes): Test for structural
10816 equivalence of enums.
10818 * ch-typeck.c (build_chill_array_ref): Convert INDEX to
10819 TYPE_MIN_VALUE of DOMAIN if the types are compatible.
10821 * ch-grant.c (chill_seize): If DECLS is a TYPE_DECL for an
10822 ARRAY_TYPE, seize the domain type if its a set.

10826 * c-typeck.c (process_init_constructor): Emit error if some
10827 array elements are not initialized.

10934 * expr.c (expand_expr): Add Chill-specific kludge for
10935 BIT_FIELD_REF if operand is SET_TYPE to call runtime function.

10937 special-case support for a BIT_FIELD_REF in right-hand-side.
10938 * ch-lang.c (finish_chill_enum): Patch up enum elements to
10939 have the correct type (instead of integers, as in C).
10941 * ch-lex.l, ch-parse.y: Add disgusting hack (involving

10982 * ch-lex.l (convert_bitstring), Changed SET_TYPE_CONSTRUCTOR to
10983 take a list of elements which are in the set. This corresponds

10986 New functions, to expand SET_TYPE CONSTRUCTORs.
10987 * varasm.c (output_constructor): Use pack_set_constructor
10988 to assemble a SET_TYPE constant from a CONSTRUCTOR.

10994 * c-typeck.c (chill_initializer_constant_valid_p): Kludge
10995 needed to export a static function.
10996 * ch-typeck.c (convert): Avoid needlessly (and lossingly) calling

11002 * ch-parse.y (location): If IDENTIFIER is a CONST_DECL

11022 * ch-expr.c, ch-loop.c, ch-process.c, ch-tree.c, ch-typeck.c: change
11023 most integer_type_node references to chill_integer_type_node.

11027 * ch-except.c: New file. Stuff for exception handling.
11028 * ch-parse.y: Add working exception handling support.
11029 * ch-lex.l, ch-parse.y: Prefer standard type terminology
11030 (BOOLS, CHARS) even though non-standard (BITS, CHAR) is ok.
11031 * ch-grant.c: Fix various problems related to granting
11032 types such as bitsets.
11033 * ch-tree.c (build_bitstring_type): Set TYPE_MIN_VALUE
11034 to distinguish bitstrings from powersets (in the same way
11035 we distinguish char strings from char arrays).

11037 * ch-tree.h, ch-actions.c (lang_init), ch-grant.c (decode_mode):
11038 Undo kludge where integer_type_node was hardwired to 16 bits.
11039 Make integer_type_node etc have the same size as in cc1.
11040 New types chill_integer_type_node and chill_unsigned_type_node
11041 that correspond to the Chill source types INT and UINT.
11042 For now, these match the C 'short' types, but that should
11043 become a configuration option later,

11052 too many/few actual parameters (and avoid seg fault).
11053 * ch-decl.c (do_decls): code cleanup for readability.
11054 * ch-loop.c (begin_chill_loop, end_chill_loop): remove
11055 emit_nop() calls - they now (since exceptions) cause seg faults.
11056 Make derogation on poor CHILL compiler non-specific.
11057 * ch-parse.y (mode2): enable VARYING keyword in CHAR(expr).
11058 * ch-tree.h: remove prototypes added to c-tree.h.
11059 * ch-typeck.c (build_chill_array_ref): correct getting domain
11060 subtree for a PARM_DECL. Subscripting a SET_TYPE is turned into

11063 Sun Feb 7 18:20:49 1993 Bill Cox (bill@rtl.cygnus.com)
11065 * ch-tree.def: add a new tree type - just for varying array
11066 references. We were using ARRAY_REF, but the underlying C
11067 code also generates that one.
11068 * ch-convert.c, ch-expr.c, ch-typeck.c: use the new tree type.
11070 Sun Feb 7 17:33:17 1993 Bill Cox (bill@rtl.cygnus.com)
11072 * ch-convert.c: test given type against type of expr before
11073 calling chill_expand_tuple. We were getting lots of spurious

11078 * cccp.c: Merge in various Chill-specific changes.
11079 * gcc.c (default_compilers array): Pass -lang-chill

11084 * Makefile.in (install-libchill, install-librmt): Removed.
11085 * ch-actions.c (build_chill_exception_decl): Change decl

11088 * ch-actions.c: Adjust interface to cause_exception accordingly.
11089 * ch-typeck.c (build_chill_array_ref): Cause rangefail if
11090 index > limit, not >= limit.

11099 and only if multiple indexes.

11109 * ch-typeck.c (chill_expand_tuple): handle set initializations better.
11111 Thu Jan 28 17:41:58 1993 Per Bothner (bothner@rtl.cygnus.com)
11113 * ch-grant.c (set_default_grant_file): Change default.
11114 Normally, grant file should end up in cwd.
11115 * ch-lang.c (build_chill_struct_type): Call pushtag,
11116 for the sake of debugging.
11117 * ch-lex.l: Improve comment parsing.

11132 supervision actions & builtins
11133 * ch-parse.y (call): eliminate optlocarrayidx, call build_chill_slice,
11134 smaller actions directly (maybe_array_ref() used to call them).
11135 * ch-tree.h: add build_chill_function_call, build_chill_slice
11136 * ch-typeck.c: add build_chill_slice()

11160 we assume check_end_label has already been called.
11161 * ch-parse.y: Put in infrastructure for exception handling.
11163 Wed Jan 27 15:45:20 1993 Bill Cox (bill@rtl.cygnus.com)
11165 * ch-actions.c: delete convert_chill_parameter, replace call with
11166 call to convert().

11168 * ch-decl.c: call convert rather than chill_give_type_to_expr.
11169 * ch-expr.c: delete chill_expand_array_assignment, move code to convert.

11211 * ch-parse.y (siezelist, grantlist): use 'name' rather than

11249 * ch-parse.y (operand5): Only allow string repetition of

11345 * ch-typeck.c (validate_varying_array_ref): re-enable constant
11346 index validation.

11362 * chill.gperf, ch-hash.h: add Wilfried's tokens
11363 * ch-lex.l: fold in Wilfried's changes. Some tokens

11378 * expmed.c (store_bit_field, extract_field_field): Undo
11379 yesterday's removal of MEM_IN_STRUCT_P "sanity test".
11381 * ch-decl.c (do_decls): Put back support for initializing.

11394 Use build_bitstring_type, not build_string_type.
11395 * expmed.c (store_bit_field, extract_field_field): Remove
11396 "sanity test" that prevents use with SET_TYPE.
11397 * tree.c (build_bitstring_type, build_powerset_type,

11476 * ch-grant.c, ch-parse.y: Remove all code for explicitly
11477 calling initializer functions. This is not needed, since we
11478 use the same mechanism used for C++ static constructors.
11479 * ch-grant.c (chill_start_module_code): Make sure the
11480 init_name starts with the magic string also used for C++
11481 initializers. Also, don't embed the file name in the name,
11482 just use the module name.
11483 * ch-grant.c (chill_finish_module_code): Now that the
11484 initializer name follows the standard 'collect' convention,
11485 don't need to call assembler_constructor_alias, but can
11486 use the standard assemble_constructor instead.
11487 * varasm.c (assemble_constructor_alias): Remove no-longer-
11488 needed function.
11489 * ch-parse.y: Move code that is common to the beginning of
11490 all functions to a new macro INIT_ACTION.

11492 * ch-parse.y (INIT_ACTION): Do chill_start_module_code()
11493 before emit_line_note(), not after.
11495 Mon Jan 4 11:43:12 1993 Bill Cox (bill@cygnus.com)
11497 * ch-parse.y: restore requirement for :upper-bound in array decl.

11528 Chill run times are now in ../chillrt, not ./chillrt.p
11530 Sat Jan 2 15:04:13 1993 Bill Cox (bill@cygnus.com)
11532 * ch-hash.h, chill.gperf: cleanup. fewer keywords seen by ch-parse.y.
11534 Sat Jan 2 13:27:49 1993 Per Bothner (bothner@rtl.cygnus.com)
11536 * ch-lex.l (check_newline): Use the orginal versions (derived
11537 from the C code, not the simplified, special-case version).
11538 Also, fix that version of check_newline to not call yylex()
11539 recursively.
11540 * ch-lex.l (yy_input): Call check_newline to handle
11541 newlines and check for # directives.
11542 * ch-lex.l (syntax): Don't recognize #-directives; these
11543 are now handled by check_newline.
11544 * ch-actions.c (lang_init): Call the modified version of
11545 check_newline(). Do this at the *after* we've initialized
11546 standard types, so this can be done while lineno is still 0.

11560 C++ defines it.
11561 * ch-grant.c (chill_start_module_code): Use JOINER character
11562 to implement name mangling for the initializer function name.
11563 Algorithm is designed to be simple, distinct from C++ mangled
11564 symbols, and easy to convert to demangled form.

11585 * ch-lang.c (convert_to_boolean, convert_to_char): Move to
11586 ch-convert.c, where they would seem to belong.
11587 * ch-convert.c (convert): New function, since we no longer
11588 link in c-convert.c.
11589 * ch-expr.c (chill_expand_assignment): Handle by calling
11590 convert() instead of chill_comptypes().
11591 Also handle the LHS being a reference.
11592 * ch-parse.y: Add a procedure call as an action.
11593 * ch-parse.y (locdec, optlocinit): Move handling of
11594 loc-identity declarations from optlocinit to locdec
11595 - and add working semantics for it.

11621 * ch-decl.c (start_chill_function): Always return 1, rather
11622 than a random value.
11623 * ch-lex.l (check_newline): Add a version for chill that
11624 just snarfs the right value for main_input_filename out of
11625 the first line of the input file, without disturbing the
11626 lexer state or requiring it's assistance.
11627 * ch-actions.c (lang_init): Call check_newline, like the
11628 other language frontends, to get main_input_filename set
11629 from first line of input file.
11631 Mon Dec 28 18:49:01 1992 Bill Cox (bill@cygnus.com)
11633 * ch-parse.y: clean up conflicts. The remaining one is
11634 harmless.

11651 Sat Dec 26 11:00:36 1992 Fred Fish (fnf@cygnus.com)
11653 * ch-grant.c (chill_finish_module_code): Call
11654 assemble_constructor_alias rather than assemble_constructor.
11655 * varasm.c (assemble_constructor_alias): New function,
11656 like assemble_constructor, but also handles the case where
11657 ASM_OUTPUT_CONSTRUCTOR is not defined and GNU ld is not
11658 being used. Emits a symbol table alias name with the correct
11659 prefix for collect to find and add to the __CTOR_LIST__.
11660 * chillrt/chillrt0.c: Build on previous hack that gets
11661 _build_exceptions into the __CTOR_LIST__, to make it work
11662 for both the non GNU-ld case and for the SVR4 case.

11706 chill_expand_result), ch-parse.y <assignaction>:
11707 Use chill_give_type_to_expr().
11708 * ch-typeck.c (chill_handle_case_label): New parameter list,
11709 to handle the (new) conventions for <case_label>, including
11710 default elements and ranges.
11711 * ch-parse.y <expanded_case_label>, ch-typeck.c
11712 (expand_case_expr): Use new version of chill_handle_case_label.
11713 * ch-decl.c (push_syndecls): Change parameters: Instead of
11714 TREE_LIST representing a compete <synonym definition statement>,
11715 just pass the parts of a single <synonym definition> as 3
11716 different parameters. Also, use chill_give_type_to_expr(),
11717 to handle untyped tuples in the RHS.
11718 * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct
11719 a tree - just call push_syndecls() on each <synonum_definition>
11720 as we see it.
11721 * ch-parse.y (exprlist_get_single): Remove; no longer needed.
11722 * ch-parse.y: Handle <tuple> without mode name diferently from
11723 <tuple> with mode name. The latter is a <primval> that can be
11724 in most contexts, but if the <mode name> is missing, the <tuple>
11725 is only allowed in certain contexts. Use the new non-terminal
11726 <untyped_expr> to indicate those contexts where untyped tuples
11727 (and case expressions) are valid because the expression gets a
11728 type from its context (such as the RHS of an assignment).
11729 Use chill_give_type_to_expr in those contexts.
11731 Sat Dec 19 14:01:26 1992 Bill Cox (bill@cygnus.com)
11733 * ch-actions.c, ch-loop.c, Makefile.in: looping stuff.
11735 Sat Dec 19 10:16:20 1992 Bill Cox (bill@cygnus.com)
11737 * ch-parse.y: clean up warning messages from byacc. bison
11738 still complains thrice.
11740 Fri Dec 18 12:33:29 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11742 * ch-actions.c (maybe_chill_comptypes): Delete unused
11743 function.
11744 (chill_comptypes): Add new parameter ERRSTR. All callers
11745 changed.
11746 (build_chill_binary_op): Fix indentation to match GNU coding
11747 style.
11749 Fri Dec 18 08:18:13 1992 Bill Cox (bill@rtl.cygnus.com)

11761 a default initializer element.
11762 * ch-parse.y: Implement default elements for tuples
11763 (as in '(else):' and '(*):' ).
11765 * ch-parse.y: Previous change to dis-ambiguate case-labels
11766 seems to have allowed getting rid of all of the expr_or_list hair.
11767 * ch-decl.c (do_decls): Undo Tiemann's change to "Handle
11768 initialization of multiple variables by a tuple" - the
11769 idea is bogus.
11771 Wed Dec 16 11:17:53 1992 Bill Cox (bill@cygnus.com)
11773 * ch-parse.y: complete re-write of DO statement handling.
11774 now operational, except WITH is stubbed out. Improved
11775 syntax error message.
11776 * ch-actions.c: DO support: high_domain_value(), low_domain_value ().
11777 * ch-expr.c: fixes to IN_EXPR handling.
11779 Tue Dec 15 17:15:13 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
11781 * ch-grant.c: Add casts to alloca return to avoid compiler warning.
11782 * ch-lex.c: Likewise.
11784 * Makefile.in (ch-lex.c): Delete incorrect free declaration added
11785 by flex to avoid compiler error.

11790 variables by a tuple.
11792 * ch-decl.c (do_decls,start_chill_function): Make DECL public
11793 if we're doing a GRANT ALL at top level.
11795 * ch-lang.c (build_range_type): Deal with typecast to CHAR in
11796 range expression.
11798 * c-typeck.c (digest_init): SET_TYPE is not a scalar type.
11799 BOOLEAN_TYPE and CHAR_TYPE are scalar types.
11801 Mon Dec 14 14:58:32 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11803 * ch-lex.l (get_chill_{linenumber,filename}): New functions.
11804 (convert_number): Use LONG_TYPE_NODE instead of INTEGER_TYPE_NODE.
11806 Mon Dec 14 13:36:44 1992 Bill Cox (bill@cygnus.com)
11808 * expr.c: install and test newer Pascal IN_EXPR code,
11809 but don't activate it - it's very verbose.
11811 Mon Dec 14 00:22:49 1992 Fred Fish (fnf@cygnus.com)
11813 * Makefile.in (LANGUAGES): Add chill.
11814 * Makefile.in (CHILL_INSTALL_NAME, CHILL_CROSS_NAME):

11829 Sun Dec 13 14:07:32 1992 Bill Cox (bill@cygnus.com)
11831 * ch-actions.c: fix unary operations, modulus ops,
11832 (discovered after extending regression tests).
11834 Sun Dec 13 12:16:32 1992 Bill Cox (bill@cygnus.com)
11836 * resync with Michael and Wilfried
11838 Sun Dec 13 09:11:25 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11840 * ch-parse.y (output_constant): Fixed some whitespace
11841 problems.
11842 * ch-tree.h: Add declarations for new chill functions that
11843 have been implemented but not (yet) declared.
11845 Sat Dec 12 00:17:23 1992 Per Bothner (bothner@cygnus.com)
11847 * c-typeck.c (process_init_constructor): Warn about duplicate
11848 labels for labelled initializer elements.
11849 * ch-lex.l (various operator tokens, such as "+"): Don't
11850 set yylval.code to a TREE_CODE; this is better done in parser.
11851 * ch-parse.y: Some work with case labels and tuples.
11852 Get literal range as tuple (and case) labels working.
11853 Fix some problems introduced by recent grammar overhaul.
11855 Fri Dec 11 13:28:48 1992 Bill Cox (bill@cygnus.com)
11857 * ch-actions.c, ch-parse.y ch-tree.h ch-expr.c, ch-typeck.c:
11858 got long, real expressions working. We can also call a func-
11859 tion and use its return value.
11861 Thu Dec 10 14:45:17 1992 Per Bothner (bothner@cygnus.com)
11863 * ch-parse.y: Major change to remove or at least identify
11864 parser ambiguities. One result: We now allow actions that
11865 start with '(', as required by teh Blue Book. This does break
11866 some things; look for FIXME for things that need work.
11867 * ch-typeck.c (chill_expand_case_expr): We need an extra
11868 level of looping to (in the future) support <case label
11869 specification>s with more than one <case label list>.
11871 Thu Dec 10 09:21:41 1992 Bill Cox (bill@cygnus.com)
11873 * ch-actions.c, ch-expr.c: Implement string assignments
11874 and relationals.
11876 Thu Dec 10 07:17:35 1992 Bill Cox (bill@cygnus.com)
11878 * ch-decl.c, ch-typeck.c: rest of previous commit.
11880 Wed Dec 9 18:26:29 1992 Bill Cox (bill@cygnus.com)
11882 * ch-parse.y, ch-actions.c, ch-expr.c: redo type checking.
11883 regression test and fix bit arrays and set ops.
11885 Mon Dec 7 14:57:46 1992 Bill Cox (bill@cygnus.com)
11887 * ch-actions.c: implement crude relationals between
11888 non-exotic operands, such as integers.
11890 Mon Dec 7 10:42:35 1992 Bill Cox (bill@cygnus.com)
11892 * ch-actions.c: implement relational, logic operations
11893 on arrays of BOOLs.
11895 Mon Dec 7 08:55:20 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11897 * ch-actions.c (lang_init): Set LINENO to 1 at beginning to
11898 indicate we are done with initialization.
11900 * ch-decl.c (do_decls): Set TREE_PUBLIC if we are doing a
11901 `grant all'.
11902 (start_chill_function): Ditto.
11904 * ch-lex.c (convert_bitstring): Set TREE_CONSTANT.
11905 (compiler_directive): Don't confuse compiler directives with
11906 equality comparison operators.
11908 * ch-parse.y: Clear CURRENT_LOCNAMELIST after calling do_decls.
11910 Sun Dec 6 13:12:32 1992 Bill Cox (bill@cygnus.com)

11919 Fri Dec 4 13:54:58 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
11921 * tree.def: Move CARD_EXPR and SET_LE_EXPR back down with the other
11922 Pascal-required ones, since C++ no longer needs them. When
11923 Chill's public, a comment can be added to the effect that
11924 SET_LE_EXPR is also used by Chill.
11926 Fri Dec 4 12:05:01 1992 Bill Cox (bill@cygnus.com)
11928 * Restore CARD_EXPR and SET_LE_EXPR to tree.def.
11930 Fri Dec 4 10:23:10 1992 Bill Cox (bill@cygnus.com)
11931 * Get *.def and *.c in sync.

11936 "ulong" from 16 bits to 32.
11937 * dwarfout.c (fundamental_type_code): Use FT_signed_char
11938 for type "byte" and FT_unsigned_char for type "ubyte".
11940 Thu Dec 3 15:13:24 1992 Bill Cox (bill@cygnus.com)
11941 * ch-actions.c, ch-tree.def, ch-parse.y: preparation
11942 for powerset expressions.
11944 Tue Dec 2 17:02:30 1992 Bill Cox (bill@cygnus.com)
11945 * ch-actions.c: sketch code for exceptions generated
11946 by builtin routines.

11955 * chill (library): Remove chillrt0.o.
11956 * chillrt/Makefile: Remove maintenance of chillrt0.o as a

11961 * ch-parse.y, ch-actions.c: add support for num()
11962 builtin function.
11964 Wed Dec 2 09:52:06 1992 Michael Tiemann (tiemann@rtl.cygnus.com)
11966 * ch-decl.c (fixup_unknown_type): New function.
11967 (push_newmode,push_synmode): Call `fixup_unknown_type' when we
11968 see a declaration that uses `unknown_type_node'. FIXME.
11970 * ch-grant.c (decode_constant): New function.
11971 (decode_decl): Call `decode_constant' for CONST_DECLs.
11973 * ch-lex.l (char action): Use ridpointers instead of
11974 lookup_name to get "char"'s declaration.
11976 * ch-parse.y: Call `build_lang_decl' instead of `build_decl'
11977 when we need to build a TYPE_DECL.
11979 Tue Dec 2 09:44:05 1992 Bill Cox (bill@cygnus.com)
11981 * ch-typeck.c: clean up a gcc warning with a forward
11982 declaration of build_string_type.
11984 Tue Dec 1 16:51:05 1992 Bill Cox (bill@cygnus.com)
11986 * ch-actions.c: completely remove those builtin calls
11987 that are duplicated in c-decl.c
11989 Tue Dec 1 16:38:51 1992 Fred Fish (fnf@cygnus.com)
11991 * ch-actions.c (lang_init): Ifdef out initializations for
11992 __builtin_abs and __builtin_fabs, since they are duplicates of
11993 initializations in c-decl.c, and trigger spurious warnings.
11995 Tue Dec 1 16:35:18 1992 Bill Cox (bill@cygnus.com)
11997 * ch-parse.y: make size() work with a typename argument.
11999 Tue Dec 1 16:15:56 1992 Bill Cox (bill@cygnus.com)
12001 * ch-parse.y, ch-lex.l, ch-actions.c: add builtin
12002 functions min, max, card.

12024 Mon Nov 30 17:35:33 1992 Fred Fish (fnf@cygnus.com)
12026 * chillsh: New script frontend (ala g++), installed as "chill".
12027 Can't be called "chill.sh" because make tries to cat it into the
12028 "chill" directory. Can't be called just "chill" cause that's
12029 already there as a directory.
12030 * Makefile.in: Add rules to install chillsh as "chill".
12031 * chill/libchill.c: Temporarily ifdef out stuff that wants
12032 to conflict with i486/SVR4 runtime or wants to pull in librmt.a,
12033 which itself causes linkage to fail.
12035 Mon Nov 30 16:28:19 1992 Bill Cox (bill@cygnus.com)
12037 * ch-lex.l: added keywords for TRUNC, ROUND, FLOAT, LFLOAT
12038 conversion routines.
12039 * ch-parse.y: added %tokens for TRUNC, ROUND, FLOAT, LFLOAT.
12040 Added production for SIZE(expr).
12041 * ch-actions.c: Add semantic routine chill_sizeof ().

12045 * ch-lex.l, ch-parse.y: Translate token PFEIL into English ARROW.
12046 * ch-parse.y (op6): Remove handling of string repetition operator,
12047 until we can figure out a way to parse it correctly.

12055 * ch-actions.c: removed compile warning, better code for abs.
12057 * ch-parse.y: add productions for builtin functions succ, pred,
12058 abs, and size. Add %tokens also. Sort %tokens alphabetically.
12060 * ch-lex.l: add parsing for builtin function names, such as abs,
12061 pred, succ, etc. Put flex -a option into Makefile.in, so we can
12062 clean up the lexer soon.
12064 Tue Nov 24 14:18:48 1992 Per Bothner (bothner@rtl.cygnus.com)
12066 * ch-typeck.c (chill_handle_case_label, chill_handle_case_default):
12067 New functions, for code common to CASE actions and expressions.
12068 * chill.y: Replace some code by calls to chill_handle_case_label
12069 and chill_handle_case_default.
12070 * ch-typeck.c (chill_expand_case_expr): Add semantics.
12072 * tree.c: Change doing_chill_thang from extern to common.
12074 Mon Nov 23 18:34:22 1992 Per Bothner (bothner@rtl.cygnus.com)
12076 * ch-tree.def: New CASE_EXPR type, for case expressions.
12077 * ch-expr.c (chill_expand_expr): Hook for CASE_EXPR.
12078 * ch-typeck.c (chill_expand_case_expr): New function.
12079 Placeholder to implement case expressions.
12080 * ch-typeck.c (chill_expand_result, chill_expand_return):
12081 Handle mode-unspecified tuples and case expressions in
12082 the context of RETURN and RESULT actions.
12083 * chill.y (assignaction): Handle case expressions in the
12084 context of the RHS of an assignment action.
12085 * chill.y (caseaction): Remove spurious duplicate OF in grammar.
12086 * chill.y: Handle labeled structure tuples.
12087 * chill.y: New rules to parse CASE expressions.
12088 * tree.c (build_function_types): Allow Chill functions
12089 to return arrays and functions.
12091 Wed Nov 18 13:50:28 1992 Per Bothner (bothner@rtl.cygnus.com)
12093 * ch-typeck.c (chill_expand_tuple): New function. Expand a
12094 tuple (constructor) given an expected (context) type.
12095 * chill.y: Implement 'LHS := TUPLE' using expand_chill_tuple,
12096 using the mode of the LHS and the expected type of the TUPLE.
12097 * chill.y: Implement initialization.
12098 * chill.y: Fix some syntax bugs (forbidlist must be surrounded
12099 by parentheses), and remove or note ambiguities.
12100 * chill.y: Started converting layout style to be like c-parse.in.
12101 * chill.y: Implement IF expressions.
12102 * chill.y: Added syntax rules for tuples. Labelled and unlabelled
12103 array tuples should now work (in some contexts).
12104 * ch-actions.c: Initialize doing_chill_thang to 1.
12105 * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
12106 initializer, to make pushdecl and finish_decl work.
12107 * c-decl.c (convert_for_assignment): If Chill, don't convert
12108 function and arrays into pointers. (Maybe functions should
12109 still be converted?)
12110 * c-typeck.c (grokdeclarator): Allow functions in Chill
12111 to return arrays and functions.
12113 Mon Nov 16 15:40:47 1992 Per Bothner (bothner@rtl.cygnus.com)
12115 * chill.y (exprlist_get_single): New function, used when
12116 parsing tuples.
12117 * chill.y: Re-did parsing of tuples to remove ambiguities.
12118 This was a bitch.
12120 Tue Nov 10 16:30:55 1992 Per Bothner (bothner@rtl.cygnus.com)
12122 * ch-typeck.c (chill_expand_result); Set TREE_SIDE_EFEFCTS
12123 flags on assignment to result.
12124 * ch-typeck.c (build_chill_array_ref): Subtract lower
12125 bound of domain if non-zero. Preliminary hook for range checking.
12126 * ch-tree.h, chill.l: Combine variables range_check and
12127 range_check_disabled into global variable range_checking.
12128 * ch-tree.h: Better definitions of CH_CLASS_IS_VALUE
12129 CH_CLASS_IS_DERIVED.
