- * decl.c (switch_to_pass_2): Revert June 13 change,
- (Don't exit after pass 1 if an error was found.)
-
- * ch-tree.def (SLICE_EXPR): New tree-code.
- * typeck.c (build_chill_slice): For building a slice of a
- bit-string, just generate a SLICE_EXPR.
- * decl.c (init_decl_processing): Declare __pscpy.
- * actions.c (chill_expand_assignment): Handle a SLICE_EXPR
- on the LHS of assignment, by calling __pscpy.
- * expr.c (chill_expand_expr): Handle SLICE_EXPR (as a RHS
- value) by using __psslice to copy slice to a temp.

-
- * Make-lang.in: Change version of GNUCHILL compiler to 1.4.1.
- * expr.c (build_chill_length): Enable LENGTH built-in to process
- Buffers and Events too (Z.200/1992).
- * lex.l (yywrap): Always set yyin to finput and/or grt_in. On
- a linux system the previous version was not able to run.
- * tasking.c: Correct processing of infinite buffer- and event-length
- to avoid RANGEFAIL warning.
-
-Thu Aug 11 11:46:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
-
- * parse.c (parse_if_expression_body): Don't call the C-specific
- build_conditional_expr. Just do build_nt (COND_EXPR, ...).
- * convert.c (convert): Convert a COND_EXPR by converting
- each branch.
-
- * convert.c (convert): Don't call convert before
- convert_to_reference. It's apt to do weird and unneedful things.
- * convert.c (convert): If the expression is varying, just call
- varying_to_slice, which simplifies quite a bit.
-
- * ch-tree.h (varying_to_slice): Add prototype.
- * typeck.c (varying_to_slice): Remove prototype.
-
- * satisfy.c (satisfy): Move case PAREN_EXPR from type 'e'
- to type '1'.
-
- * except.c (emit_setup_handler): Temporarily reset the
- maximum_field_alignment to zero so the compiler's exception
- data structures can be compatible with the run-time system,
- even when we're compiling with -fpack.
-
- * expr.c (compare_records): Call saved_if_needed on operands.
-
- * expr.c (build_set_expr case NE_EXPR): Don't use __nepowerset
- which has been reimplemented to just call __eqpowerset and
- invert the result. Inline this new implementation by
- handling as EQ_EXPR, and inverting the result.
- * decl.c (init_decl_processing): Don't define unused __eqpowerset.
-
- * typeck.c (valid_array_index_p): The TRUTH_ANDIF_EXPR has
- type boolean_type_node, not void_type_node. (Fixing this
- avoids a crash in the back-end.)
-
- * grant.c (decode_constant): In a CALL_EXPR, if the argument
- list is not a TREE_LIST (as in string repetiation), don't
- emit parentheses.
-
-Wed Aug 10 13:13:55 1994 Per Bothner (bothner@kalessin.cygnus.com)
-
- * decl.c (proclaim_decl): Use CH_DECL_ENUM to check that a
- CONST_DECL is from a SET definition. (This is safer than
- checking that the type is ENUMERAL_TYPE, because synonym
- definitions may have a NULL TREE_TYPE.)
- Also, if we have duplicate enums whose types are identical,
- this is an error.
- * decl.c (proclaim_decl, pushdecllist, push_scope_decls): Add
- an extra 'quiet' parameter, which is true if we're called from
- bind_sub_modules. (In that case an error message about duplicated
- decls would be repeated later, so suppress it.)
-
- * parse.c (stmt_count): Removed, not used.
- (INIT_ACTION): Call emit_line_note only if !ignoring.
- (parse_begin_end_block): Do INIT_ACTION even if ignoring.

-
- * parse.c (parse_untyped_expr): Fix various problem for the
- case that we see a '(': Add missing 'case' keyword.
- Only recurse if '(' is followed by 'if', 'case' or '[',
- and in that case emit a pedwarn (and do a missing NEXT_TOKEN).
-

-
- * tasking.c (build_copy_number, build_proc_type, expand_send_signal):
- Check the type of the instance expr using CH_COMPATIBLE,
- and not just == instance_type_node. (This allows
- the expression to have mode READ INSTANCE).
- * tasking.c (build_instance_type): Give instance_type_node
- a non-null novelty (i.e. different from a struct).
- * tasking.c (build_receive_case_start, build_delay_case_start):
- Check that for a location using CH_LOCATION_P.

-
-Mon Jul 11 15:33:52 1994 Per Bothner (bothner@kalessin.cygnus.com)
-
- * convert.c (digest_structure_tuple): Don't use convert to

- build_chill_addr_expr.
-
- * loop.c (build_temporary_variable): Stylistic tweak.
- * loop.c (maybe_make_for_temp): Initialize temp using

-
- * lex.l (yywrap): Kludge to work around mis-synchronization
- between lexer (which read ahead) and parser: Don't emit
- (left-over) uze_seizefile directives at the end of file.
-
- * typeck.c (build_chill_array_ref): Allow the derived
- array indexing syntax for arrays of bit strings.
- Add a comment explaining why.
-
- * typeck.c, ch-tree.h (string_assignment_condition): Change
- the interface. Return a boolean expression (which can be
- used in a conditional at run-time); never expand anything.
-
- * actions.c (chill_convert_for_assignment): Check
- string_assignment_condition here, rather than in callers.
- * actions.c (chill_expand_assignment): Don't need to check
- string_assignment_condition here.
- * expr.c (build_chill_function_call): Likewise.
- * satisfy.c (safe_satisfy_decl): Update accordingly.
- * decl.c (do_decl): Simplify testing and conversion by
- deferring everything to chill_convert_for_assignment.
-
- * parse.c: Combine the two variables 'ignore_exprs' and
- 'ignore_actions' into one variable called 'ignoring'.
- * ch-tree.h: Add 'extern int ignoring'.
- * actions.c, except.c, parse.c, tasking.c, timing.c, typeck.c:
- Rename ignore_actions and ignore_exprs to ignoring.
- Remove unneeded extern declarations.
- * expr.c (build_chill_indirect_ref, build_chill_component_ref,
- build_chill_arrow_expr, build_generalized_call, build_delay_action,
- build_buffer_type, build_event_type): I changed my mind. It is
- cleaner to check for 'ignoring' in the parser, rather than here.
- * parse.c (parse_action, parse_primval, parse_opt_mode):
- Therefore we must check for ignoring here.
- * parse.c (parse_loc_declaration): Set ignoring in pass 2
- when parsing the mode.
-

- parameter level have same nesting level as body, as required by Z200.
- * decl.c (switch_to_pass_2): Always exit if an error has been found.
- * decl.c (pop_module): Copy DECL_SEIZEFILE to a new ALIAS_DECL
- generated from GRANT ALL.
- * decl.c (lookup_name_for_seizing): Don't seize from
- the nesting level of builtins (predefined objects).
- * decl.c (lookup_name_for_seizing): Make more robust on error.
-
- * decl.c (start_chill_function): MAKE DECL_NAME (chill_result_decl)
- be 'RESULT' (or 'result'). This makes it more accessible from gdb.
- Also, use do_decl to declare it, so that debugging symbols are
- generated. And, re-arrange so that actions that need to
- be done both passes (such as push_levels) use the same code.
-
- * parse.c (get_type_of): If ignore_exprs, don't lookup name.
- * parse.c (end_function): Fix poplevel params.
- * parse.c (expect): Don't read forwards on an error.
- * parse.c (parse_field): Don't define two tag_list locals!
- * parse.c (parse_pass_1_2): Better error message.
-
- * parse.c (parse_mode, parse_opt_mode): Have parse_mode call
- parse_opt_mode, rather than vice versa. If parse_opt_mode

- return NULL_TREE if there is no mode (even on ignore_exprs).
- (parse_set_mode, parse_structure_mode, parse_procedure_mode):
- Never return NULL_EXPR.
- * tasking.c (build_buffer_type, build_event_type): Return

-
- * parse.c (parse_synonym_definition): Call parse_untyped_expr
- only if we have a mode.
- * parse.c (parse_send_action): Parse list of untyped_expr's,
- rather than a list of (typed) expressions.
- * parse.c (parse_primval): Emit error if '[' seen without
- preceding mode name. (If this is to be allowed, call
- parse_untyped_expr instead.)
-
- * parse.c (parse_array_index): Renamed to ...
- (parse_index_mode): ... to match Z200 terminology.
- Re-write to resolve some of the nastier ambiguities,
- and allow things like ' CHAR(10) : CHAR(20) '.
-
- * parse.c (parse_tuple_element): Change interface to return
- reversed list, so don't call nreverse.
- * parse.c (parse_tuple): No longer nreverse element list here.
- * parse.c (parse_opt_element_list): Do nreverse here instead.
- * parse.c (parse_case_label_list): Call nreverse at end.

- * typeck.c (build_chill_slice): Use TYPE_ARRAY_MAX_SIZE.
- * expr.c (chill_expand_expr case CONCAT_EXPR): Likewise.
- * convert.c (convert): When converting a fixed string/array
- to varying, and we need padding, set the TYPE_ARRAY_MAX_SIZE
- of (the type of) the padding.
- * convert.c (convert): If the concatenation is non-constant, use
- the low-level 'build' to set the type of the result (which is usually
- a fixed-size array) rather than depend on build_chill_binary_op
- to figure it out (it's unable to simplify the size to a constant).
-
-Mon Jun 6 18:16:57 1994 Per Bothner (bothner@kalessin.cygnus.com)
-
- * lang.c (lang_decode_option): Let -fspecial_UC imply

-Tue May 31 18:12:00 1994 Per Bothner (bothner@kalessin.cygnus.com)
-
- * convert.c (digest_constructor): Check that initial value
- is compatible with element mode before calling convert.
- * typeck.c (chill_compatible): A string mode is not compatible
- with an untyped constructor.
- * decl.c (do_decl): Clean up error messages. Use error_with_decl.

- __define_timeout and __wait_timeout.
-
-Wed May 25 11:53:09 1994 Per Bothner (bothner@kalessin.cygnus.com)
-
- Replace yacc-based parser with a recursive-decent parser.
- (This may seem backwards, but Chill [like C++] is not a
- language that is remotely LALR(1). Using a R-D parser
- allows us to use look-ahead and to back-up to resolve the
- difficult ambiguities.)
- * parse.y: Removed.
- * parse.c, parse.h: New files, containing new r-d parser.
- * Makefile.in: Update accordingly.
- * actions.c (chill_convert_for_assignment): Don't return
- NULL_EXPR if ignore_exprs is true. It simplifies the parser
- if we consistently reserve NULL_EXPR for a missing expression.
- * expr.c (build_chill_function_call): Likewise.
-
- * lex.l: Tweaks for new parser.
- * lex.l (prepare_paren_colon, paren_paren_colon_level,
- paren_level): Ugly hack no longer needed.
-
- * expr.c (build_chill_function_call): Cleanup.
- Call chill_convert_for_assignment to convert IN/INOUT

- "place" string used in error messages).
- * actions.c (adjust_parm_or_field): Removed.
- * actions.c (chill_expand_assignment): Take just a single LHS,
- and move support for multiple assignments to ...
- (expand_assignment_action): ... here. Some cleaning up.
- * timing.c (build_cycle_start): Adjust accordingly.
- * actions.c (expand_assignment_to_varying_array): Likewise.
- * tasking.c (many places): Ditto.
- * ch-tree.h: Fix declarations appropriately.
-
- * parse.c (parse_defining_occurrence_list): Return a single
- IDENTIFIER_NODE (instead of a singleton list) in the common
- case. Minor complication to save a minor amount of space.
- * decl.c (do_based_decls): Move guts of code into ...
- (do_based_decl): ... this new function.
- * decl.c (do_decls): Handle either IDENTIFIER_NODE or a TREE_LIST.
- * decl.c (push_syndecl): Replace by ...
- (push_syndecl): ... (which only supports a single name).
- (push_modedef): Only handle a single name.
- * tasking.c (build_process_header, build_signal_struct_type):

-
- * expr.c (build_generalized_call): Handle string repetition.
- * expr.c (build_chill_repetition_op): Change interface.

-
- * lex.l (make_identifier): Replaced by ...
- (read_identifier, handle_name): ... new functions.
- * lex.l: Parse an identifiers using read_identifier using
- read_identifier and handle_name, rather than having [f]lex
- do it. (One reason is that lex uses a fixed-size buffer.)
-
- * lex.l (read_directive, skip_directive): New functions.
- Use them to parse compiler-directives, instead of rather
- ugly and useless use of lexer start conditions.
-
-Tue May 24 22:36:51 1994 Per Bothner (bothner@kalessin.cygnus.com)
-
- * decl.c (unnamed_module_number): Renamed to ...
- (module_number): .. and make non-static.
- (push_module): Always increment module_number.
- * lex.l (yywrap): Print warning if no modules seen.
-
- * decl.c (pop_module): Don't set DECL_SEIZEFILE of granted
- decl to current_seizefile_name (which is unreliable).
- * grant.c (chill_grant): Set it here instead.
-
- * expr.c (fold_set_expr): Use int_size_in_bytes instead of
- TYPE_PRECISION (which is not defined for a SET_TYPE).
-
-Fri May 20 15:21:26 1994 Per Bothner (bothner@kalessin.cygnus.com)
-
- Cleanup to remove need for variables in common storage.

-
-Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
-
- * grant.c (decode_mode): Remove. It checks the TYPE_NAME of
- the input type, which loses with the no-longer-new 2-pass
- implementation, since the input "type" could be an IDENTIFIER_NODE.
- * grant.c (raw_decode_mode): Rename to decode_mode.
-
-Tue May 17 13:19:52 1994 Per Bothner (bothner@kalessin.cygnus.com)

- pointer-to-function.
- * expr.c (build_chill_indirect_ref, build_chill_component_ref,
- build_chill_arrow_expr): If ignore_exprs, return operand
- rather than NULL_EXPR. This makes it easier for the parser to
- distinguish missing expressions.
- * expr.c (build_max_min): Convert the lower bound of a
- set to a long before calling run-time routine.
- * expr.c (build_chill_pred_or_succ): Use discrete_type_p
- to check the argument type.
- * expr.c (build_chill_arrow_expr): If argument is not a location,
- do a predwarn if it is a STRING_CST or has function type.

-
- * decl.c (build_chill_function_type): Don't call layout_type
- (since that may prevent parameter or result types being
- properly satisfied).
- * satisfy.c (satisfy): Layout FUNCTION_TYPEs.
- * parse.y (procmode): Call build_chill_pointer_type, rather

-
- * parse.y (get_type_of): Handle TYPE_DECL (again).
- * parse.y (optresultspec): Call build_chill_reference_type, rather
- than build_reference_type (which incorrectly sets TYPE_SIZE).

-
- New cleaner solution to the following problem:
- Chill allows an action to be followed by an ON-handler.
- But we don't know if an action has a handler until we've parsed
- its end, yet we want to generate extra code to set up an
- exception handling contour only if needed. The old solution
- would generate code for the action into an rtl sequence, and then
- splice in the exception-setup code if we later found we needed it.
- This has a few problems (for example it confuses the management
- of stack temporaries), and is ugly. Now that the compiler is 2-pass
- we have a cleaner solution: In pass 1, we remember which actions
- were followed by ON-handlers. In pass 2, we use this information
- to generate appropriate code before an action.
- * except.c (push_handler, pop_handler): In pass 1, set up data
- structures (global_handler_list) to remember if an action has an
- ON-handler. In pass 2, digest this information, and setup
- handler if needed.
- * except.c, actions.h (pop_handler): Take an extra int arg.
- * except.c (emit_setup_handler): New function, with code (moved

- (local to ../stmt.c) getting out of sync.
- * actions.c (push_action): Don't need to emit a NOP,
- now that we're no longer moving sequences around.
- * actions.c (push_action): Call push_handler even in pass one.

-
- * ch-decl.c (do_decl): Keep OPT_INIT in DECL_INITIAL if possible.

- to handle VAR_DECLs as initializers.
-
- * ch-convert.c (digest_structure_tuple): Copy elements of INITS so

-

- * varasm.c (output_constant): Handle NOP_EXPRs in SET_TYPE
- CONSTRUCTORS.

- (digest_struct_tuple): Defend against initialization machinery
- mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both

- can be refered to throughout the compilation unit. Also remove an
- extraneous call to `process_init_element' erroneously added to the
- variant record sub-loop.
- (digest_constructor): Propagate TREE_CONSTANT and TREE_STATIC to
- CONSTRUCTORS of SET_TYPE.
- * ch-parse.y (build_chill_constructor): Refix typo. Also set
- TREE_STATIC if at top level.

- TREE_CONSTANT not being set by calling `build1' when `build_unary_op'
- should have been called.
-
- * ch-convert.c (digest_struct_tuple): Restore code which tracks
- field initializations so that the compiler can deduce what variant
- initializations to assume.
-
- * ch-satisfy (safe_satisfy_decl): Turn on initialization machinery
- when we push into a scope that has a DECL with a CONSTRUCTOR as its
- DECL_INIT.

- parameter to something more meaningful. Fix typo. Also, handle case
- where element is an untyped CONSTRUCTOR.
-
- * ch-except.c (finish_handler_array): Set TREE_CONSTANT on
- constant ADDR_EXPRs.
- (chill_start_on): Call `build_unary_op' to set TREE_CONSTANT

- * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
- that are created here.
- * ch-satisfy (satisfy): Abort in case we would have called

- propagate TREE_CONSTANT bits to CONSTRUCTORS.
- (untyped_expr rule): Use it.
- (primval rule): Use it.

-
- * ch-decl.c (do_decl): Change in CONSTRUCTOR handling due to...
- * ch-convert.c (digest_structure_tuple,digest_constructor): Mostly
- rewritten to work with GCC's initialization code. The basic change
- was to keep the initializers in sync with the initialization
- machinery that `process_init_element' imposes. Both of these
- functions now return `void'.
- * ch-convert.c (convert): Changed calls to `digest_...' functions.
-
- FIXME: the code handling UNION_TYPE (and variant records) has not
- been tested yet.

-
- This fixes 'X // := Y' and is also a general simplification.
- * ch-actions.c (chill_expand_assignment): Convert 'LHS OP := RHS'
- to 'LHS := LHS OP RHS' (using stabilize_reference on LHS).
- Also, call save_expr on RHS if a multiple assignment.

- code saving value from build_process_header. Delete redundant chill_
- phrases from some function calls.

- new enum types to a given input list. This makes it easier to

- Also, handle FUNCTION_DECL.
- * ch-decl.c (bind_saved_names): Removed. Distribute its
- functionality over new functions (push_scope_decls, pop_scope_decls,
- build_implied_names, bind_sub_modules). The goal (which seems to
- have been more-or-less attained) was to fix weak name handling.
- * ch-decl.c (poplevel): Use new function pop_scope_decls.
-
- * ch-tasking.c (build_signal_struct, build_tasking_message_type):
- Use build_decl directly, rather than grok_chill_fixedfields
- (which depends on ignore_exprs and has more overhead).
- * ch-tasking.c (build_signal_struct): Construct the type
- only in pass 1.
- * ch-typeck.c (build_chill_slice): Use my_build_array_ref rather
- than build_array_ref (which does C-specific "optimizations").

- `decl_temp1' to declare TASKING_CODE_NAME.
- (tasking_setup): Drop into 1-pass mode so that all
- tasking-related declarations are installed in the global
- scope. Use correct CHILL types for initializers (since
- ptr_type_node doesn't have the right meaning for CHILL).
- Also, call `do_decl' instead of `decl_temp1' for
- `init_struct'.
- (add_taskstuff_to_list): Set TASKING_LIST in pass 1 to keep
- `chill_finish_compile' in sync between passes.
-
- * ch-decl.c (do_decl): Set DECL_ASSEMBLER_NAME for
- declarations on pass zero. Keep obstacks in sync, and always
- call `finish_decl' for pass zero declarations.

- call `finish_decl' for pass zero declarations.
- (build_enumerator): Ditto.

- * ch-grant.c (chill_finish_compile): Clear out both
- MODULE_INIT_LIST and TASKING_LIST if either contains stuff
- from pass one.
-
- * ch-parse.y (rccase_label): Add NAME rules so that pass one
- works w/o knowing we're parsing a signal. Simplify SIGNALNAME
- rules since we only get SIGNALNAME tokens in pass two.
- (sendaction): Ditto.
- * ch-lex.l (name_type_signal): Enable returning SIGNALNAME and
- BUFFERNAME on pass two. The grammar now handles this.
- * ch-decl.c (lookup_remembered_decl): Deleted.

-
- * ch-decl.c (lookup_remembered_names): Removed. It was being
- misused in ch-lex.l.
- * ch-lex.l (name_type_signal): Revert last change. Basically,
- we cannot use the C typedef/variable name trick in CHILL, due
- due to the language's 2-pass nature.
- * ch-parse.y (arrayindex): Rewrite for correctness, and to avoid
- a seg fault.
- * ch-tree.h (lookup_remembered_name): Comment out the prototype.

- New variables. The latter replaces in_seizefile.
-
- Changes to store in the new DECL_SEIZEFILE field each seize
- ALIAS_DECL the name in the most recent use_seize_file directive.
- (This requires that use_seize_file directives written to the
- grant file be written before the SEIZEs that need it.)
- Allow clashing declarations granted into the global scope
- (produce a warning), but remember the seizefile case from
- (using the DECL_SEIZEFILE field of the grant ALIAS_DECL).
- The a SEIZE will select the granted decl that matches its
- DECL_SEIZEFILE (in other words: grants from the most recent

-
- * Makefile.in: Change installation of the chill script. gcc will
- be called always with the full path. That made problems when
- somebody was using chill but didn't have the installation
- directory in PATH.
- * ch-parse.y: Change parsing of WRITETEXT action.
- * ch-tree.h: Add some new prototypes according to the
- (partial) implementation of WRITETEXT.
- * ch-typeck.c: Add new function chill_varying_string_type_p. This
- functions checks a type for being CHAR(n) VARYING.
- * ch-decl.c (init_decl_processing): Add new built-in functions
- _writestring and _writeunixstd.
- Add call to build_chill_io_list_type in ch-inout.c.
- * ch-inout.c (build_chill_writetext): Add some code there.
- Add new function build_chill_io_list_type.
- Add new static function chill_stdio_p. This function checks
- the text argument for being chill_stdin, chill_stdout or
- chill_stderr.

- * ch-tree.h (TYPE_TAG_FIELD renamed to TYPE_TAGFIELDS), ch-grant.c
- (print_struct), ch-parse.y (opttagfield -> opttagfields), ch-decl.c
- (make_chill_variants, layout_chill_variants): Add (initial) part
- of support for multiple tags.
- * ch-decl.c (lookup_tag_fields): New function.
- * ch-parse.y (stmt_count): Not used; removed.

- temporary for an non-referencable actual parameter
- passed to a LOC formal parameter.
- (chill_expand_assignment): Correct compatibility checking.
-
- * ch-decl.c (push_modedef): Set up a type's NOVELTY value.
- * ch-parse.y (opsigdest): Only check for process name
- in pass 2, when we know.

-
- * ch-grant.c (lookup_decl_in_process, register_decl_as_output,
- decl_seen_p, processed_decls, allocated, nr_decls): Removed
- no-longer-useful functions and variables that used to guard
- against writing a decl multiple times. Since we now just
- go through the decl list linearly, that is no longer an issue.
- * ch-satisfy.c (safe_satisfy_decl): Handle missing current_module.
-
- * ch-decl.c (start_chill_function): Clear DECL_ASSEMBLER_NAME.
- Don't make TREE_PUBLIC. Don't generate rtl yet.

- * ch-grant.c (grant_one_decl): Don't set TREE_PUBLIC.
- * ch-tree.h (struct module): New field prefix_name.

- * ch-typeck.c (chill_similar): Flesh out substantially.
- * ch-typeck.c (chill_compatible): Re-structure.
-
- * ch-actions.c (adjust_parm_or_field): Use CH_COMPATIBLE
- instead of chill_comptypes to compare actual and formal.

-
- * ch-parse.y (labellist): Don't do anything if ignore_exprs.
-
- * c-typeck.c (output_pending_init_elements): Handle
- !constructor_incremental case of filling in empty positions.
- (Patch by Jim Wilson. CYGNUS LOCAL until we have approval.)
- * ch-decl.c (pop_module): Don't grant a seized name.
- * ch-grant.c (decode_constant): Support CALL_EXPR.
- * ch-tree.c (build_bitstring_type): Don't try to fold non-constant
- size if pass==1 (since it may be an unsatisfied name).

-
- 2-pass fixes for processes. Partially done.
- * ch-actions.c (chill_expand_assignment): Add real
- novelty-checking sketch, $ifdef'd out for now.
- * ch-decl.c: Generally fix indentation. Move tasking
- init code from init_decl_processing to ch-tasking.c.
- Delete ObjC-related cruft. More accurate parameter name
- for shadow_record_fields. Move debug_scope before
- its first call.
- * ch-expr.c (build_chill_function_call): Return if not
- pass 2.
- * ch-grant.c (print_proc_tail): Avoid trying to format
- a VOID return type, or using a NULL pointer.
- (decode_decl): Minor changes for PROCESS arg access.
- * ch-lang.c (lang_decode_option): Use -itu flag to
- enable 'pedantic' mode.
- * ch-lex.l (init_lex): Initialize compiler-directive
- variable trees.
- (name_type-signal): Disable the returning of SIGNAL and BUFFER
- name tokens.
- * ch-parse.y (rccase_label_flag): Renamed from rccase_ifs.
- All uses renamed also.
- (end_function): Always poplevel, not just in pass 2.
- (quasi_pdef): Check for end-label matching.
- (quasi_formparlist): Write more clearly.
- (rcaltlist, optelsercvcase, optstartset): Add ignore_actions
- guards.
- (rccase_label, sendaction): Use NAME, not SIGNALNAME
- or BUFFERNAME.
- (process): Handle like procedure.
- (mode): Add SIGNAL as a generic signal parameter. This
- is a client-specific extension, so pedantic is checked.
