+ build_chill_addr_expr.
+
+ * loop.c (build_temporary_variable): Stylistic tweak.

+Tue Jun 14 16:44:14 1994 Per Bothner (bothner@kalessin.cygnus.com)
+
+ * lex.l (yywrap): Kludge to work around mis-synchronization

+ (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.

+ * 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:

+ * 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

+ * 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_pass_1_2): Better error message.
+
+ * parse.c (parse_mode, parse_opt_mode): Have parse_mode call

+ Change parse_opt_mode (and any functions it calls) to only
+ 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)

+
+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
+ paramaters on both input and output. For LOC parameters,

+ "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 ...

+ (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)

+
+ * expr.c (fold_set_expr): Use int_size_in_bytes instead of

+
+Wed May 18 13:27:12 1994 Per Bothner (bothner@kalessin.cygnus.com)
+
+ * grant.c (decode_mode): Remove. It checks the TYPE_NAME of

+
+ * typeck.c (build_chill_slice_with_length): Fix type-checking.

+
+ 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
+ from chill_start_on) to emit code before an action that has a handler.

+ (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.
+ This is needed because variables may appear in initialization

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

+
+ * ch-actions.c: Fix comments.

+

+ CONSTRUCTORS.
+
+Sun Jan 2 08:17:09 1994 Michael Tiemann (tiemann@blues.cygnus.com)

+ `convert' so we can handle INSTANCE types (and other anomolies)
+ correctly.
+
+ * ch-convert.c (digest_structure_tuple): Fixed variant

+ (digest_struct_tuple): Defend against initialization machinery
+ mucking with CONSTRUCTOR_ELTS of CONSTRUCTORs by grokking both
+ IDENTIFIER_NODEs and FIELD_DECLs in the TREE_PURPOSE slots. This is
+ needed because CONSTRUCTORS stored in DECL_INITIALs of CONST_DECLs
+ 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.

+ * ch-expr.c (build_chill_arrow_ref): Fix yet another case of
+ 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.
+
+ * ch-parse.y (build_chill_constructor): Change the name of the
+ 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-convert.c (convert): Test LENGTH instead of NEEDED_PADDING.
+

+ come through here.
+ * ch-except.c (finish_handler_array): Ditto for CONSTRUCTORS
+ that are created here.
+ * ch-satisfy (satisfy): Abort in case we would have called
+ chill_expand_tuple. FIXME: some other code is needed here,
+ but I don't know what yet.
+
+ * ch-parse.y (build_chill_constructor): New function to
+ propagate TREE_CONSTANT bits to CONSTRUCTORS.
+ (untyped_expr rule): Use it.
+ (primval rule): Use it.
+

+ missing prototypes.
+
+Fri Dec 31 11:31:01 1993 Michael Tiemann (tiemann@blues.cygnus.com)
+
+ * ch-grant.c (chill_finish_module_code): Mark ADDR_EXPR built by hand
+ as being TREE_CONSTANT. Otherwise it gets bounded by the initializer
+ code.
+
+ * 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.
+
+Fri Dec 31 15:32:56 1993 Bill Cox (bill@rtl.cygnus.com)

+
+ * ch-decl.c (push_scope_decls): Re-arrange so that normal

+
+Sun Sep 26 13:09:57 1993 Bill Cox (bill@rtl.cygnus.com)

+
+Sat Sep 25 13:54:41 1993 Per Bothner (bothner@kalessin.cygnus.com)
+
+ * ch-decl.c: Expand pre-amble comment.
+ * ch-decl.c (struct scope, push_module): Use new field
+ tail_chain_module to build child-module list in order.
+ (Just to make compiler debugging a little less confusing.)
+
+ * ch-decl.c (struct scope): New field weak_decls.
+ * ch-decl.c (find_implied_types): New interface. Now pre-pend
+ new enum types to a given input list. This makes it easier to
+ avoid duplicates, which should at least be more efficient.
+ 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").
+ (Hence move my_build_array_ref up earlier in the file.)
+
+Sat Sep 25 03:47:28 1993 Michael Tiemann (tiemann@blues.cygnus.com)
+
+ * ch-tasking.c: Declare static variable `void_ftype_void'.
+ (chill_tasking_init): Initialize `void_ftype_void' here.
+ (build_tasking_struct): Use, don't declare `void_ftype_void'.
+ (generate_tasking_code_variable): Call `do_decl', not
+ `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.
+ (push_chill_extern_function): Keep obstacks in sync, and always
+ call `finish_decl' for pass zero declarations.
+ (build_enumerator): Ditto.
+ (grok_chill_variantdefs): Change PASS test to exclude only

+ * ch-decl.c (build_chill_exception_decl): Clarify reasons for
+ extra pushing and popping of obstacks.
+
+ * ch-inout.c (build_chill_io_list_type): Call `satisfy_decl'
+ on IO_DESCRIPTOR. This causes IO_DESCRIPTOR to be laid out.
+
+ * 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.
+
+Fri Sep 24 15:27:13 1993 Bill Cox (bill@cygnus.com)
+
+ * 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.
+
+Fri Sep 24 11:01:31 1993 Michael Tiemann (tiemann@blues.cygnus.com)

+ (pushlevel, poplevel) Change pass checks.
+ (pushdecl): Check type as well for NULL.
+ (build_enumerator): Handle pass == 0 case.
+ * ch-lex.l: Use lookup_remembered_decl to get lastiddecl
+ during pass 1.
+ * ch-parse.y: Set pass to zero to indicate initial decl processing.
+ Replace NAME references with SIGNALNAME references.
+ (startaction): Only check copy number if not ignoring actions.
+ Always call build_chill_start_process.
+ (optstartset): Don't lookup the instance name.
+ * ch-tasking.c (generate_tasking_code_variable): Replace
+ do_decl call with decl_temp1 call.
+ (build_chill_start_action): Check for ignore_actions here.
+ (build_tasking_message_type): Layout the type.
+ (rc_state_type): New structure to keep nested receive-case

+
+
+Fri Sep 24 04:19:15 1993 Michael Tiemann (tiemann@blues.cygnus.com)
+
+ * ch-tasking.c (build_chill_receive_case_start): `namedecl'

+
+ * ch-tree.h (CH_ROOT_RESULTING_MODE): New macro.
+ * ch-lex.l (use_seizefile_name, current_seizefile_name), ch-tree.h:
+ 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
+ use_seize_file will be preferred).
+ * ch-tree.h (DECL_SEIZEFILE), ch-tree.def: New macro.
+ * ch-tree.h (global_value, IDENTIFIER_GLOBAL_VALUE): Renamed
+ to outer_value, IDENTIFIER_OUTER_VALUE.
+ Changes to cause the use_seize_file directives to be written
+ out in order as they're seen in source.
+ * ch-lex.l (files_to_seize, next_file_to_seize, last_file_to_seize):
+ Changed to have type TREE_LIST of pointer to IDENTIFIER_NODE.

+ Don't call grant_use_seizefile.
+ * ch-lex.l (mark_use_seizefile_written): New function.
+ * ch-grant.c (decode_decl): Write out use_seize_file directive,
+ if needed, before writing a seize declarations.
+ * ch-decl.c (pop_module): Handle decls granted into the global
+ module specially, setting IDENTIFIER_OUTER_VALUE.
+ * ch-decl.c (lookup_name_for_seizing): Check IDENTIFIER_OUTER_VALUE.
+
+Thu Sep 23 19:05:37 1993 Bill Cox (bill@cygnus.com)

+
+ Major re-write of New module/seize/grant stuff.
+ Now, a grantfile is a spec module and contains all the
+ top-level declarations of the granting module, not just
+ those that are granted. It also contains explicit grant
+ statments naming those declared names that are granted.
+ It also has seize statements and use_seize_file directives
+ to correctly handle transitive dependencies.
+
+ * ch-parse.y: Change to allow multiple modules per source file.
+ Allow spec modules (including quasi definitions) as well as
+ regular modules.
+ Allow spec modules inside normal modules; these behave as if
+ they were outermost. This violates the Blue Book, but is
+ needed by the new grantfile mechanism. (A grant file is a
+ spec module that gets included by the use_seize_file directive.)
+ * ch-parse.y (struct module *current_module, push_module,
+ pop_module): Support module nesting (for spec modules only).
+
+ * ch-tree.h (struct module): New.

+ that have been granted into the outermode pseudo-module.
+ * ch-grant.c (decode_mode): If the decl has a name,
+ always write the name, not just if the decl has already

+ * ch-lex.l (syntax): Don't recognize #-directives; these
+ are now handled by check_newline.
+ * ch-actions.c (lang_init): Call the modified version of

+ prefix for collect to find and add to the __CTOR_LIST__.
+ * chillrt/chillrt0.c: Build on previous hack that gets

+ * ch-decl.c (push_syndecls): Change parameters: Instead of

+ different parameters. Also, use chill_give_type_to_expr(),
+ to handle untyped tuples in the RHS.
+ * ch-parse.y <syndeclist, syndef>: Don't bother trying to construct

+ as we see it.
+ * ch-parse.y (exprlist_get_single): Remove; no longer needed.
+ * ch-parse.y: Handle <tuple> without mode name diferently from
+ <tuple> with mode name. The latter is a <primval> that can be
+ in most contexts, but if the <mode name> is missing, the <tuple>
+ is only allowed in certain contexts. Use the new non-terminal
+ <untyped_expr> to indicate those contexts where untyped tuples
+ (and case expressions) are valid because the expression gets a
+ type from its context (such as the RHS of an assignment).
+ Use chill_give_type_to_expr in those contexts.

+ already there as a directory.
+ * Makefile.in: Add rules to install chillsh as "chill".
+ * chill/libchill.c: Temporarily ifdef out stuff that wants
+ to conflict with i486/SVR4 runtime or wants to pull in librmt.a,

+ abs, and size. Add %tokens also. Sort %tokens alphabetically.
+
+ * ch-lex.l: add parsing for builtin function names, such as abs,
+ pred, succ, etc. Put flex -a option into Makefile.in, so we can
+ clean up the lexer soon.

+ context of the RHS of an assignment action.
+ * chill.y (caseaction): Remove spurious duplicate OF in grammar.
+ * chill.y: Handle labeled structure tuples.
+ * chill.y: New rules to parse CASE expressions.
+ * tree.c (build_function_types): Allow Chill functions
+ to return arrays and functions.
+
+Wed Nov 18 13:50:28 1992 Per Bothner (bothner@rtl.cygnus.com)
+
+ * ch-typeck.c (chill_expand_tuple): New function. Expand a
+ tuple (constructor) given an expected (context) type.
+ * chill.y: Implement 'LHS := TUPLE' using expand_chill_tuple,
+ using the mode of the LHS and the expected type of the TUPLE.
+ * chill.y: Implement initialization.
+ * chill.y: Fix some syntax bugs (forbidlist must be surrounded
+ by parentheses), and remove or note ambiguities.
+ * chill.y: Started converting layout style to be like c-parse.in.
+ * chill.y: Implement IF expressions.
+ * chill.y: Added syntax rules for tuples. Labelled and unlabelled
+ array tuples should now work (in some contexts).
+ * ch-actions.c: Initialize doing_chill_thang to 1.
+ * ch-decl.c (do_decls): Set DECL_INITIAL if there is an
+ initializer, to make pushdecl and finish_decl work.
+ * c-decl.c (convert_for_assignment): If Chill, don't convert
+ function and arrays into pointers. (Maybe functions should
+ still be converted?)
+ * c-typeck.c (grokdeclarator): Allow functions in Chill
+ to return arrays and functions.

+
+ * chill.y (exprlist_get_single): New function, used when
+ parsing tuples.
+ * chill.y: Re-did parsing of tuples to remove ambiguities.
+ This was a bitch.
+
+Tue Nov 10 16:30:55 1992 Per Bothner (bothner@rtl.cygnus.com)
+
+ * ch-typeck.c (chill_expand_result); Set TREE_SIDE_EFEFCTS
+ flags on assignment to result.
+ * ch-typeck.c (build_chill_array_ref): Subtract lower
+ bound of domain if non-zero. Preliminary hook for range checking.
+ * ch-tree.h, chill.l: Combine variables range_check and
