2039 routine named build_eh_type_type.
2040 (build_eh_type_type): New routine.
2041 (expand_start_catch_block): Use build_eh_type_type, as we never want
2042 the dynamic type of the catch parameter, just the static type.
2043 Fixes core dumps when -frtti is used and one catchs pointers to
2046 Thu Aug 10 14:55:29 1995 Mike Stump <mrs@cygnus.com>
2048 * except.c (expand_builtin_throw): Since we now use normal calling
2049 conventions for __throw, we have to remove the first layer off the
2050 stack, so that the next context we search for handlers is the outer
2051 context instead of the context that had the call to __throw, if we
2052 don't immediately find the desired context.

2077 * except.c (make_first_label): Remove.
2078 (init_exception_processing): Don't use a LABEL_REF for throw_label,
2079 instead use a SYMBOL_REF, this is so that we don't use LABEL_REFs in
2080 other functions that don't really appear in those functions. This
2081 solves a problem where cc1plus consumed exponential amounts of
2082 memory when -Wall was used.

2084 expand_end_catch_block, expand_throw): Change all uses of
2085 throw_label to match new style.
2086 (do_unwind): Rename parameter to inner_throw_label, as it is now

2090 throw is now a real function.

2127 InsnSave. Also, numerous speed improvements, and correctness
2128 improvements. Double faulting in all situations should now be
2130 (expand_start_all_catch): Instead of having many terminate protected
2131 regions, just have one.
2132 (expand_start_catch_block): No longer have to protect
2133 false_label_rtx, as it isn't used for EH region marking.
2134 (expand_end_catch_block): Expand out EH cleanups here by using
2135 expand_leftover_cleanups.
2136 (expand_end_all_catch): Use sequences instead of playing with insn
2138 (expand_exception_blocks): Ditto. Also protect all catch clauses
2139 with one terminate region.

2143 * method.c (report_type_mismatch): Don't talk about an object

2194 * tree.def (UNSAVE_EXPR): New tree code.
2195 * typeck.c (c_expand_return): Move goto/return code up inside

2201 * parse.y (typespec): Only complain about typeof if we're not

2261 is not a parameter list (TREE_LIST).

2596 * sig.c (build_signature_table_constructor): Use DECL_CONTEXT
2597 instead of DECL_CLASS_CONTEXT for calculating the vfield offset so
2598 abstract virtual functions are handled correctly.
2600 * sig.c (build_signature_table_constructor): Store the correct
2601 delta in signature table entries. It does not yet work for
2602 classes with virtual base classes as implementations of signatures.
2603 (build_signature_method_call): Add the delta to the object_ptr
2604 before generating the function call.
2606 * call.c (build_method_call): Make instance_ptr the signature

2617 message that said we can't handle multiple inheritance for
2618 implementations of signatures
2619 (build_signature_method_call): Use the offset from the sigtable
2620 entry instead of the vptr field from the signature pointer for

2624 call this function anymore from build_signature_method_call.
2626 * cp-tree.h (SIGNATURE_VPTR_NAME): Deleted. We use the right vptr

2643 the way digest_init does, digest_init can't handle initializing an

2646 delta field to get the vtable index.

2655 hold the identifiers for the sigtable fields tag and offset.
2656 (init_decl_processing): Initialize these variables.
2657 (init_decl_processing): Use these variables to build the
2658 sigtable_entry_type structure. Rename the code and offset fields
2659 to tag and delta, respectively; add offset and index fields. Changed
2660 types of fields from short_integer_type_node to delta_type_node.
2661 * sig.c (build_signature_table_constructor): Rename code and offset
2662 to tag and delta, respectively.

2677 among all instantiations, we have to substitute in the real types
2678 in TREE_TYPE (parm).
2679 pt.c (coerce_template_parms): Ditto.
2680 (push_template_decls): Ditto.
2681 (grok_template_type): Deleted as template parameters are shared

4438 here, rather than from xref_defn_tag.
4440 * parse.y (do_xref): Lose.
4441 (named_class_head): If we see 'class foo:' we know it's a
4442 definition, so don't worry about base lists for non-definitions.
4444 * pt.c (push_template_decls): Template parm decls are artificial.
4446 * decl.c (duplicate_decls): Restore check for qualifier
4447 disagreement for non-functions.

4503 (finish_file): Move finish_prevtable_vardecl up to before the global
4504 initializers are done as tdecls are initialized in the global
4505 initializer. Also Pick up any new tdecls or vtables needed by
4506 synthesized methods.
4508 * class.c (finish_struct): Simplify. We have to do rtti scanning at
4509 end, so we might as well do all of it there.

4513 * call.c (build_method_call): Fix -fthis-is-variable for 32-bit

4522 in finish_prevtable_vardecl.
4523 * decl2.c (finish_file): Call finish_prevtable_vardecl.
4524 * gc.c (build_generic_desc): Allow it to be called when not at the
4525 global binding layer, but behave as if we were.
4526 (build_t_desc): Rearrange a bit so that it really works and is
4528 * class.c (finish_struct): Don't decide on tdecls here, as we have
4529 to wait until the end of the file in general to decide whether or
4532 Mon Jan 30 01:00:40 1995 Jason Merrill <jason@phydeaux.cygnus.com>

4542 * call.c (build_method_call): Ditto.
4544 * call.c (convert_harshness): Make conversion from a pointer to bool

4561 Sat Jan 28 09:10:44 1995 Mike Stump <mrs@cygnus.com>
4563 * decl2.c (finish_vtable_vardecl): Now set the
4564 interface/implementation of vtables on the first virtual function,
4565 if one exists, otherwise we use the old method. This is a major win
4566 in terms of cutting down the size of objects and executables in
4567 terms of text space and data space. Now most of the savings that
4568 #pragma interface/implementation gives is automatic in a fair number

4573 * decl.c (grokdeclarator): Discard the template parameters in a

4587 * parse.y: Add END_OF_LINE token.
4589 * lex.c (check_newline): Set linemode when we see a # directive, and
4590 unset it when we're done. Turn all 'return's into 'goto skipline'.
4591 Fix all uses of '\n', since we won't see it anymore. Put back the
4592 character we read before checking for a sysv or target pragma.
4593 (real_yylex): If we see an EOF in linemode, return END_OF_LINE.
4594 (handle_sysv_pragma): Don't look at the input stream; quit when we
4595 see an END_OF_LINE token.
4597 * input.c (getch): Return EOF if we're in line mode and at the end
4599 (put_back): Don't put back an EOF.

4609 * except.c (init_exception_processing): Don't use r12 on the rs6000.

4615 * typeck2.c (build_functional_cast): Don't assume that a NOP_EXPR
4616 will suffice to convert from integer_zero_node.
4618 Wed Jan 25 15:02:09 1995 David S. Miller (davem@nadzieja.rutgers.edu)
4620 * class.c (instantiate_type): Change error message text.
4621 * typeck2.c (store_init_value): Likewise.
4623 Mon Jan 23 21:57:14 1995 Mike Stump <mrs@cygnus.com>

8340 (pushdecl_nonclass_level): New function for pushing mangled decls of
8341 nested types into the appropriate scope.
8342 (xref_defn_tag): Use pushdecl_nonclass_level instead of
8344 (grokfndecl): Don't mess with IDENTIFIER_GLOBAL_VALUE for local
8346 * method.c (do_inline_function_hair): Ditto.
8348 * class.c (finish_struct): It is legal for a class with no
8349 constructors to have nonstatic const and reference members.
8351 Thu Apr 14 07:15:11 1994 Brendan Kehoe (brendan@lisa.cygnus.com)
8353 * decl.c (push_overloaded_decl): Avoid giving errors about
8354 built-ins, since duplicate_decls will have given warnings/errors
8357 Thu Apr 14 03:45:12 1994 Jason Merrill (jason@deneb.cygnus.com)
8359 * cvt.c (convert_to_reference): Warn about casting pointer type to
8360 reference type when this is probably not what they wanted.
8362 Wed Apr 13 13:12:35 1994 Per Bothner (bothner@kalessin.cygnus.com)
8364 * decl.c (finish_decl): Don't mindlessly set TREE_USED for
8365 static consts any more (toplev.c has now been modified to
8366 not emit warnings if they are unused).
8368 Wed Apr 13 00:22:35 1994 Jason Merrill (jason@deneb.cygnus.com)
8370 * decl.c (grok_op_properties): If op new/delete get here with
8371 METHOD_TYPEs, do a revert_static_member_fn.
8373 * cp-tree.h (IDENTIFIER_CLASS_TYPE_VALUE): Lose.
8374 * init.c (is_aggr_typedef): Don't look at
8375 IDENTIFIER_CLASS_TYPE_VALUE.
8376 (get_aggr_from_typedef): Ditto.
8377 (get_type_value): Ditto.
8378 * call.c (build_scoped_method_call): Don't rely on overloaded
8379 template names having IDENTIFIER_CLASS_VALUE set.
8381 * parse.y (component_decl_1, fn.def2): Revert rules for
8383 (component_decl_1, fn.def2): Use $1 instead of $$, since $$ is being
8386 * decl.c (start_function): Only warn about `void main()' if pedantic
8387 || warn_return_type.
8389 Tue Apr 12 02:14:17 1994 Jason Merrill (jason@deneb.cygnus.com)
8391 Clean up overloading of the template name.
8392 * class.c (pushclass): overload the template name whenever pushing
8393 into the scope of a template class, not just if it is
8395 (popclass): Correspondingly.
8396 * search.c (push_class_decls): Don't overload_template_name.
8397 * pt.c (overload_template_name): Don't set IDENTIFIER_LOCAL_VALUE or
8398 DECL_CONTEXT on things.
8399 * parse.y (left_curly): Don't overload_template_name.
8400 * class.c (finish_struct): Don't undo_template_name_overload.
8402 * method.c (build_opfncall): Only pass one argument to global op
8405 * call.c (build_method_call): Use TYPE_VEC_DELETE_TAKES_SIZE to
8406 decide how many arguments to use for vec delete.
8408 * decl.c (grok_op_properties): Be consistent in modifying
8410 (grokdeclarator): Only complain about function decls with no return
8411 type if we're being pedantic.
8413 Mon Apr 11 00:10:53 1994 Jason Merrill (jason@deneb.cygnus.com)
8415 Add support for operator new [] and operator delete [].
8417 * tree.def: Add VEC_NEW_EXPR and VEC_DELETE_EXPR.
8418 * ptree.c (print_lang_type): Indicate vec new/delete.
8419 * parse.y: Support vec new/delete.
8420 * method.c (build_decl_overload): Deal with vec new/delete.
8421 (build_opfncall): Ditto.
8422 * lex.c (init_lex): Set up values of ansi_opname and opname_tab for
8423 vec new/delete. vec new uses "__vn", and vec delete uses "__vd".
8424 * init.c (init_init_processing): Set up BIVN and BIVD.
8425 (do_friend): Don't clean up after mistaken setting of TREE_GETS_NEW,
8426 since it doesn't happen any more.
8427 (build_new): Support vec new. Always call something.
8428 (build_x_delete): Support vec delete.
8429 (build_vec_delete): Lose dtor_dummy argument, add use_global_delete,
8430 and pass it to build_x_delete.
8431 * decl2.c (delete_sanity): Don't change behavior by whether or not
8432 the type has a destructor. Pass use_global_delete to
8434 (coerce_delete_type): Make sure that the type returned has a first
8435 argument of ptr_type_node.
8436 * decl.c (init_decl_processing): Also declare the global vec
8438 (grokdeclarator): Also force vec new/delete to be static.
8439 (grok_op_properties): Note presence of vec new/delete, and play with
8440 their args. If vec delete takes the optional size_t argument, set
8441 TYPE_VEC_DELETE_TAKES_SIZE.
8442 * cp-tree.h (TYPE_GETS_{REG,VEC}_DELETE): New macros to simplify
8443 checking for one delete or the other.
8444 (lang_type): gets_new and gets_delete are now two bits long. The
8445 low bit is for the non-array version. Lose gets_placed_new.
8446 (TYPE_VEC_DELETE_TAKES_SIZE): New macro indicating that the vec
8447 delete defined by this class wants to know how much space it is
8449 (TYPE_VEC_NEW_USES_COOKIE): New macro to indicate when vec new must
8450 add a header containing the number of elements in the vector; i.e.
8451 when the elements need to be destroyed or vec delete wants to know
8453 * class.c (finish_struct_methods): Also check for overloading vec
8455 * call.c (build_method_call): Also delete second argument for vec
8458 * decl.c (grokdeclarator): Correct complaints again.
8459 (grokdeclarator): Fix segfault on null declarator.
8460 (decls_match): Also accept redeclaration with no arguments if both
8461 declarations were in C context. Bash TREE_TYPE (newdecl) here.
8462 (duplicate_decls): Instead of here.
8464 * parse.y (nested_name_specifier_1): Lose rules for dealing with
8465 syntax errors nicely, since they break parsing of 'const i;'.
8467 * decl.c (lookup_name): if (got_scope == current_class_type)
8468 val = IDENTIFIER_CLASS_VALUE (name).
8470 * search.c (lookup_nested_tag): Look in enclosing classes, too.
8472 * spew.c (yylex): Only look one character ahead when checking for a
8475 * lex.c (check_newline): Read first nonwhite char before
8476 incrementing lineno.
8478 * decl.c (grokdeclarator): Don't claim that typedefs are variables
8481 * parse.y: Divide up uses of unqualified_id into
8482 notype_unqualified_id and unqualified_id, so that TYPENAME can be
8483 used as an identifier after an object.
8485 * class.c (push_nested_class): Don't push into non-class scope.
8487 * decl.c (grokdeclarator): If an identifier could be a type
8488 conversion operator, but has no associated type, it's not a type
8489 conversion operator.
8491 * pt.c (unify): Check for equality of constants better.
8493 * decl.c (grokdeclarator): Don't complain about access decls.
8495 Sun Apr 10 02:39:55 1994 Jason Merrill (jason@deneb.cygnus.com)
8497 * decl.c (grokdeclarator): pedwarn about data definitions without
8500 * parse.y (datadef): Don't pedwarn about decls without types here,
8501 since that is valid for functions.
8502 (fn.def2, component_decl): Support constructors with declmods again.
8503 (nomods_initdecls): For decls without any mods, so that we don't try
8504 to get declspecs from some arbitrary $0.
8506 * search.c (lookup_field): Use cp_error.
8508 * parse.y (nested_name_specifier_1): Don't check aggr/non-aggr type
8509 here; it breaks destructors for non-aggr types.
8511 * decl.c (lookup_name): Only look for TYPE_DECLs in base classes of
8512 a type being defined, like the comment says.
8513 If got_scope is not an aggregate, just return NULL_TREE.
8515 * pt.c (create_nested_upt): Kung's code for creating types nested
8516 within uninstantiated templates now lives here (it used to live in
8517 hack_more_ids). It needs to be expanded.
8519 * parse.y: Stop calling see_typename so much.
8521 * decl.c (lookup_name): Deal with TTPs and UPTs.
8523 * lex.c (real_yylex): Don't set looking_for_typename just because we
8525 (dont_see_typename): #if 0 out.
8527 * spew.c (yylex): Increment looking_for_typename if the next
8528 character is SCOPE, rather than setting it to 1; this way, the value
8529 from seeing an aggr specifier will not be lost. This kinda relies
8530 on looking_for_typename never being < 0, which is now true.
8532 * parse.y (nested_name_specifier_1): Accept TEMPLATE_TYPE_PARMs,
8534 (named_class_head_sans_basetype): Accept template types, too. Oops.
8536 Fri Apr 8 16:39:35 1994 Jason Merrill (jason@deneb.cygnus.com)
8538 * decl2.c (reparse_decl_as_expr1): Handle SCOPE_REFs.
8540 * parse.y: Lose START_DECLARATOR.
8542 * search.c (lookup_nested_tag): New function to scan CLASSTYPE_TAGS
8545 * parse.y: Simplify fn.def2 and component_decl. Support 'enum
8546 A::foo' syntax. Catch invalid scopes better.
8548 * parse.y, lex.c: lose TYPENAME_COLON.
8550 * decl2.c (groktypefield): #if 0 out.
8552 * decl.c (lookup_name): If the type denoted by got_scope is
8553 currently being defined, look in CLASSTYPE_TAGS rather than FIELDS.
8555 * class.c (push_nested_class): Don't try to push into
8558 Fri Apr 8 07:26:36 1994 Brendan Kehoe (brendan@lisa.cygnus.com)
8560 * Makefile.in (stamp-parse): Update count of conflicts to 33.
8562 Thu Apr 7 17:47:53 1994 Jason Merrill (jason@deneb.cygnus.com)
8564 A saner implementation of nested types that treats template types
8565 no differently from non-template types. There are still some
8566 shortcomings of our system; most notably, it is difficult to look
8567 for a nested type that is hidden by another name, because of the way
8568 we keep track of hidden types. But this shouldn't be a problem for
8569 just about anyone. Perhaps lookup_field should be fixed up a bit.
8571 * spew.c: Moved handling of nested types/scoping from the lexer
8572 into the parser. Removed variable template_type_seen_before_scope.
8573 Removed functions frob_identifier, hack_more_ids, and various cruft
8574 that was #if 0'd out in the past, reducing the size of the file from
8575 1146 lines to 450 lines. We can't quite do away with spew.c yet,
8576 though; we still need it for do_aggr () and checking for SCOPE after
8577 the current identifier. And setting lastiddecl.
8579 * parse.y: Moved handling of nested types/scoping from the lexer
8580 into the parser, using a new global variable `got_scope'. Reduced
8581 the number of states by 53. Implemented all uses of explicit global
8582 scope. Removed terminals SCOPED_TYPENAME and SCOPED_NAME. Removed
8583 nonterminals tmpl.1, scoped_base_class, id_scope, typename_scope,
8584 scoped_typename. Added nonterminals nested_type,
8585 qualified_type_name, complete_type_name, qualified_id, ptr_to_mem,
8586 nested_name_specifier, global_scope, overqualified_id, type_name.
8587 Changed many others. Added 9 new reduce/reduce conflicts, which are
8588 nested type parallels of 9 that were already in the grammar for
8589 non-nested types. Eight of the now 33 conflicts should be removed
8590 in the process of resolving the late binding between variable and
8593 * gxxint.texi (Parser): Update.
8595 * cp-tree.h (IS_AGGR_TYPE_CODE): Add UNINSTANTIATED_P_TYPE.
8597 * lex.h: Add decl for got_scope.
8599 * lex.c (see_typename): Claim to be the lexer when calling
8602 * decl.c (lookup_name): When called from the lexer, look at
8603 got_scope and looking_at_typename; otherwise don't.
8605 Thu Apr 7 22:05:47 1994 Mike Stump <mrs@cygnus.com>
8607 31th Cygnus<->FSF merge.
8609 Thu Apr 7 17:47:53 1994 Jason Merrill (jason@deneb.cygnus.com)
8611 * decl2.c (mark_vtable_entries): Call this to mark all the
8612 entries in the vtable addressable.
8613 (finish_decl_parsing): Handle SCOPE_REFs.
8615 * decl.c (decls_match): Always call compparms with strict == 1.
8616 Handle the special case of C function redecl here.
8617 (duplicate_decls): Only keep the old type if the new decl takes no
8620 * typeck.c (compparms): Also allow t1 to be ... if strict == 0.
8622 Thu Apr 7 16:17:50 1994 Mike Stump <mrs@cygnus.com>
8624 * class.c (build_vtable_entry): Fix breakage introduced Apr 5
8627 Wed Apr 6 16:05:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
8629 * init.c (build_virtual_init), search.c (build_vbase_vtables_init),
8630 ch-tree.h: Every place these functions were called, the result was
8631 immediately passed to expand_expr_stmt. Reduce redundancy by
8632 calling expand_expr_init *inside* these functions. These
8633 makes for a simpler interface, and we don't have to build
8634 compound expressions. Hence, rename these function to:
8635 expand_virtual_init and expand_vbase_vtables_init respectively.
8636 * init.c, decl.c: Change callers of these functions.
8637 * init.c, cp-tree.h (expand_virtual_init): Make static.
8639 * decl2.c (finish_file): Check TREE_PUBLIC||TREE_ADDRESSABLE
8640 rather than DECL_SAVED_INSNS before emitting inlines.
8642 Wed Apr 6 13:06:39 1994 Jason Merrill (jason@deneb.cygnus.com)
8644 * spew.c (init_spew): #if 0 out stuff used by arbitrate_lookup.
8646 * decl.c (duplicate_decls): If this is a new declaration of an
8647 extern "C" function, keep the type (for the argtypes).
8648 (redeclaration_error_message): Don't check DECL_LANGUAGE here.
8649 (decls_match): Call compparms with a value of strict dependent on
8650 the value of strict_prototypes for DECL_LANGUAGE (oldecl).
8652 * typeck.c (compparms): ... is only equivalent to non-promoting
8653 parms if we're not being strict.
8655 * parse.y (empty_parms): Don't check flag_ansi || pedantic here.
8657 * decl.c (init_decl_processing): if (flag_ansi || pedantic)
8658 strict_prototypes_lang_c = strict_prototypes_lang_cplusplus;
8660 * decl2.c (grok_function_init): Don't set DECL_INITIAL on pure
8663 Tue Apr 5 17:48:41 1994 Per Bothner (bothner@kalessin.cygnus.com)

8666 * tree.def (THUNK_DECL): New TREE_CODE.
8667 * cp-tree.h (FNADDR_FROM_VTABLE_ENTRY), tree.c
8668 (fnaddr_from_vtable_entry): Handle flag_vtable_thunks case.
8669 * cp-tree.h (memptr_type): New variable.
8670 * class.c (build_vtable_entry): Build thunk if necessary.
8671 * class.c (build_vfn_ref): If using thunks, don't need
8672 to add delta field from vtable (there is none!).
8673 * decl.c: Add memptr_type as well as vtable_entry_type.
8674 If using thunks, the latter is just ptr_type_node.
8675 * gc.c, typeck.c: Use memptr_typeChange, not vtable_entry_type.
8676 * decl2.c (finish_vtable_vardecl): Handle thunks.
8677 * expr.c (cplus_expand_expr): Support THUNK_DECL.
8679 * decl.c (grokdeclarator): Set DECL_THIS_EXTERN if "extern".
8680 * decl.c (start_function): Set current_extern_inline based on
8681 DECL_THIS_EXTERN, not TREE_PUBLIC.
8682 * decl.c (finish_function): Call mark_inline_for_output if needed,
8684 Improve intelligence about when to emit inlines.
8685 * cp-tree.h (lang_decl_flags): New field saved_inline.
8686 * cp-tree.h (DECL_SAVED_INLINE): New macro.
8687 * class.c (add_virtual_function): Don't set TREE_ADDRESSABLE.
8688 * decl.h, decl.c (pending_addressable_inlines): Removed.
8689 * decl2.c (pending_addressable_inlines): Renamed to saved_inlines.
8690 * decl2.c (mark_inline_for_output): Do nothing if
8691 DECL_SAVED_INLINE; otherwise set it (and add to saved_inlines list).
8692 * decl2.c (finish_vtable_vardecl): SET_CLASSTYPE_INTERFACE_KNOWN
8693 and set CLASSTYPE_INTERFACE_ONLY if there is a non-inline virtual.
8694 * decl2.c (finish_file): Writing out inlines later, so we can
8695 also handle the ones needed for vtbales.
8696 * decl2.c (write_vtable_entries, finish_vtable_typedecl): Removed.
8698 * cp-tree.h, class.c, decl2.c, search.c: Remove -fvtable-hack
8699 and flag_vtable_hack. Use -fvtable-thunks and flag_vtable_thunks
8700 instead. (The rationale is that these optimizations both break binary
8701 compatibility, but should become the default in a future release.)
8703 Wed Apr 6 10:53:56 1994 Mike Stump <mrs@cygnus.com>
8705 * class.c (modify_vtable_entries): Never reset the DECL_CONTEXT
8706 of a fndecl, as we might not be from that vfield.
8708 Tue Apr 5 17:43:35 1994 Kung Hsu (kung@mexican.cygnus.com)
8710 * class.c (add_virtual_function): fix bug for pure virtual, so
8711 that DECL_VINDEX of the dummy decl copied won't be error.
8712 (see also Apr 4 change)
8714 Tue Apr 5 17:23:45 1994 Per Bothner (bothner@kalessin.cygnus.com)
8716 * typeck.c (c_expand_return): Before checking that we're not
8717 returning the address of a local, make sure it's a VAR_DECL.
8718 (And don't worry about it being a TREE_LIST.)
8720 Tue Apr 5 13:26:42 1994 Jason Merrill (jason@deneb.cygnus.com)
8722 * parse.y (YYDEBUG): Always define.
8723 * lex.c (YYDEBUG): Ditto.
8725 Mon Apr 4 11:28:17 1994 Kung Hsu (kung@mexican.cygnus.com)
8727 * class.c (finish_struct): backup out the change below, put the
8728 new change for the same purpose. The change below breaks code.
8730 * class.c (finish_struct): if pure virtual, copy node and make
8731 RTL point to abort, then put in virtual table.
8732 * decl2.c (grok_function_iit): reinstate Mar 31 change.
8734 Sat Apr 2 03:12:58 1994 Jason Merrill (jason@deneb.cygnus.com)
8736 * init.c (build_new): pedwarn about newing const and volatile
8739 * tree.c (get_identifier_list): Only do the special handling
8740 thing if we're dealing with the main variant of the record type.
8742 * cvt.c (convert_to_reference): When converting between
8743 compatible reference types, use the pointer conversion machinery.
8744 Don't just blindly overwrite the old type.
8746 Fri Apr 1 17:14:42 1994 Jason Merrill (jason@deneb.cygnus.com)
8748 * call.c (build_method_call): When looking at global functions,
8749 be sure to use instance_ptr for the first argument, not some version
8750 of it that has been cast to a base class. Also do this before
8751 comparing candidates.
8753 Thu Mar 31 19:50:35 1994 Jason Merrill (jason@deneb.cygnus.com)
8755 * call.c (build_method_call): Constructors can be called for
8758 Thu Mar 31 16:20:16 1994 Kung Hsu (kung@mexican.cygnus.com)
8760 * decl2.c (grok_func_init): do not abort as rtl for pur virtual
8761 fucntions. They can be defined somewhere else.
8763 Sat Jan 23 23:23:26 1994 Stephen R. van den Berg (berg@pool.informatik.rwth-aachen.de)
8765 * decl.c (init_decl_processing): Declare __builtin_return_address
8766 and __builtin_frame_address for C++ as well.
8768 Thu Mar 31 12:35:49 1994 Mike Stump <mrs@cygnus.com>
8770 * typeck2.c (store_init_value): Integral constant variables are
8771 always constant, even when doing -fpic.
8773 Sat Jan 23 23:23:26 1994 Stephen R. van den Berg (berg@pool.informatik.rwth-aachen.de)
8775 * decl.c (redeclaration_error_message): Pass the types to
8778 Wed Mar 30 21:29:25 1994 Mike Stump <mrs@cygnus.com>
8780 Cures incorrect errors about pure virtuals in a class, when they
8781 have been overridden in a derived class.
8783 * search.c (get_abstract_virtuals): Reimplement.
8784 * search.c (get_abstract_virtuals_1): New routine.
8786 Wed Mar 30 14:10:04 1994 Jason Merrill (jason@deneb.cygnus.com)
8788 * pt.c (push_template_decls): Make the pushed level pseudo
8791 * parse.y (extdefs): Don't pop everything if the current binding
8792 level is pseudo_global.
8794 * decl.c (pop_everything): Stop on reaching a pseudo-global
8797 * cp-tree.h (DECL_FUNCTION_MEMBER_P): Change to more reliable test.
8799 * decl.c (duplicate_decls): Only copy DECL_SOURCE_{FILE_LINE} if
8800 the old decl actually had an initializer.
8802 * {various}: Clean up gcc -W complaints.
8804 * cp-tree.h (DECL_FUNCTION_MEMBER_P): Currently defined to be
8805 (DECL_CONTEXT (NODE) != NULL_TREE).
8807 * parse.y (lang_extdef): Call pop_everything if necessary.
8809 * decl.c (pop_everything): New function for popping binding
8810 levels left over after a syntax error.
8811 (pushdecl): Use DECL_FUNCTION_MEMBER_P to decide whether or not
8812 a function is a member.
8814 Wed Mar 30 14:20:50 1994 Mike Stump <mrs@cygnus.com>
8816 Cures calling a more base base class function, when a more derived
8817 base class member should be called in some MI situations.
8819 * search.c (make_binfo): Use more the more specialized base
8820 binfos from the binfo given as the second argument to make_binfo,
8821 instead of the unspecialized ones from the TYPE_BINFO.
8822 * class.c (finish_base_struct): Ditto, update callers.

8824 * tree.c (propagate_binfo_offsets, layout_vbasetypes): Ditto.

8870 * decl.c (start_method): Methods defined in the class body are
8871 inline whether or not it's a template class.

9043 * decl.c (grokdeclarator): Set TREE_PUBLIC for METHOD_TYPE
9044 in FIELD context, when appropriate. Also,

9074 (pop_from_top_level): Restore them.
9076 * gxxint.texi (Parser): Update.
9078 These two patches finish moving the task of expr/declarator
9079 ambiguity resolution from the lexer to the parser, and add one more

9089 * spew.c (yylex): #if 0 out START_DECLARATOR insertion.
9091 These two patches disable some excessive cleverness on the part of
9092 g++; a non-class declaration always hides a class declaration in the
9093 same scope, and g++ was trying to unhide it depending on the
9094 enclosing expression.
9096 * spew.c (arbitrate_lookup): #if 0 out.
9098 * decl.c (lookup_name): Never call arbitrate_lookup.
9100 * parse.y (complex_notype_declarator1): Add '*'

9110 These changes fix the compiler's handling of the functional cast/
9111 object declaration ambiguities in section 6.8 of the ARM. They also
9112 add 11 reduce/reduce conflicts. Sigh.

9115 (notype_unqualified_id): New nonterminal, encompasses all of the
9116 ANSI unqualified-id nonterminal except TYPENAMEs.

9124 an expr_or_declarator.
9125 (complex_direct_notype_declarator): A direct_notype_declarator that
9126 doesn't conflict with expr_or_declarator. Use
9127 notype_unqualified_id. Remove id_scope see_typename TYPENAME rule.
9128 (functional_cast): New nonterminal, for the three functional cast
9129 rules. So that they can be moved after
9130 complex_direct_notype_declarator.
9131 (see_typename): Don't accept type_quals any more.
9133 * decl2.c (reparse_decl_as_expr): New function to deal with parse
9134 nodes for code like `int (*a)++;'.
9135 (reparse_decl_as_expr1): Recursive subroutine of the above.
9136 (finish_decl_parsing): New function to deal with parse nodes for
9137 code like `int (*a);'. See the difference?
9139 Thu Mar 17 12:16:10 1994 Mike Stump <mrs@cygnus.com>
9141 These changes break binary compatibility in code with classes
9142 that use virtual bases.
9144 * search.c (dfs_get_vbase_types): Simplify and correct to make
9145 sure virtual bases are initialized in dfs ordering.
9146 * search.c (get_vbase_types): Simplify and make readable.
9148 Thu Mar 17 12:01:10 1994 Jason Merrill (jason@deneb.cygnus.com)

9161 Wed Mar 16 17:43:07 1994 Jason Merrill (jason@deneb.cygnus.com)
9163 * parse.y (direct_notype_declarator): Add PTYPENAME rule, remove
9164 all of the scoped PTYPENAME rules.
9166 Wed Mar 16 16:39:02 1994 Mike Stump <mrs@cygnus.com>
9168 * init.c (build_offset_ref): The value of A::typedef_name is
9169 always the TYPE_DECL, and never an error.
9171 Tue Mar 15 20:02:35 1994 Jason Merrill (jason@deneb.cygnus.com)
9173 * search.c (get_base_distance_recursive): Two binfos can only
9174 represent the same object if they are both via_virtual.
9176 * class.c (finish_base_struct): Check vbases for ambiguity, too.
9178 * search.c (get_vbase_types): Accept binfo argument, too.
9180 Tue Mar 15 19:22:05 1994 Kung Hsu (kung@mexican.cygnus.com)
9182 * decl.c (complete_array_type): complete TYPE_DOMAIN of the
9183 initializer also, because back-end requires it.
9185 Tue Mar 15 15:33:31 1994 Jason Merrill (jason@deneb.cygnus.com)
9187 * error.c (dump_expr): Support member functions (which show up as

9237 * decl2.c (reparse_decl_as_expr): Recursive function to change
9238 parse nodes for `A()()' from "function returning function returning

9269 op= problems with virtual inheritance.
9271 * decl2.c (grokoptypename): Just does grokdeclarator and
9272 build_typename_overload, since the parser can't call grokdeclarator

9329 direct_after_type_declarator, direct_abstract_declarator): Split up

9349 * parse.y (typed_declspecs, declmods): It's not necessary to hash

9355 * cvt.c (build_up_reference): If we aren't checking visibility,

9372 a non-inline virtual function to control emitting of vtables.
9373 * class.c (finish_struct): Build CLASSTYPE_METHODS list.
9374 * search.c (build_vbase_vtables_init): Don't assemble_external

9394 * lex.c (check_newline): #pragma interface can take a string
9395 argument, just like #pragma implementation. #pragma implementation
9396 checks for garbage on the line, line #pragma interface does. Main
9397 input files do not auto implement like named files, #pragma
9398 implementation must be used explicitly.

9412 * Makefile.in (stamp-parse): Update expected conflict count.
9414 * parse.y (various): Replace "declmods declarator" with "declmods
9415 notype_declarator". The comment saying that "declmods declarator ';'"
9416 corresponds to "int i;" was wrong; it corresponds to "const i;".
9417 (component_decl): Add "typed_declspecs declarator ';'" rule; this
9418 *does* correspond to "int i;". Change "declmods components" to
9419 "declmods notype_components".
9420 (components): Don't deal with a list of one anymore.
9421 (notype_components): New nonterminal, corresponds to notype_declarator.

9464 that we are calling ourselves recursively, so a partial match is OK.
9465 (unify): Support pointers to methods and functions.
9466 (tsubst): Support method pointers.
9467 * decl.c (build_ptrmemfunc_type): No longer static, so that

9477 * pt.c (do_function_instantiation): Ditto.
9478 * class.c (instantiate_type): Ditto.

9507 * class.c (build_vfn_ref): Cast delta field to ptrdiff_type_node,

9512 * decl.c (build_ptrmemfunc_type): Make sure that the pmf type
9513 goes onto the same obstack as its target type.

9517 * cvt.c (convert_to_reference): If converting via constructor
9518 on local level, go back to build_cplus_new approach.
9520 * tree.c (build_cplus_new): If with_cleanup_p, set cleanup slot
9521 to error_mark_node to prevent expand_expr from building a cleanup
9524 * lex.c (default_assign_ref_body): Return *this from the memcpy
9527 * decl.c (grok_reference_init): Just return if called with
9528 error_mark_node, don't worry about initializing non-const reference
9531 * cvt.c (convert_to_reference): Do the right thing for
9532 non-aggregate reference conversions, pedwarn when generating a
9533 non-const reference to a temporary.
9535 * class.c (finish_struct): TYPE_HAS_COMPLEX_{INIT,ASSIGN}_REF and
9536 TYPE_NEEDS_CONSTRUCTING all depend on TYPE_USES_VIRTUAL_BASECLASSES

9541 * decl.c (grok_reference_init): Pawn off a lot of the work on
9542 convert_to_reference. Generally do the right thing.
9544 * cvt.c (convert_to_reference): Conform to the initial comment;
9545 i.e. don't create temps if decl != error_mark_node. Handle
9546 cleanups better for temps that do get created. Don't pretend
9547 that we can use an 'A' to initialize a 'const double &' just by
9548 tacking on a NOP_EXPR. Support LOOKUP_SPECULATIVELY.
9550 * call.c (build_method_call): Set TREE_HAS_CONSTRUCTOR on

9562 (which isn't always the inner_binding_level).
9564 * cvt.c (build_up_reference): Don't ever call expand_aggr_init.
9565 It's ugly, and I don't think it's the right thing to do.
9567 * cp-tree.h, class.c, decl.c, decl2.c, sp/search.c:
9568 Remove NEW_CLASS_SCOPING, assuming it is always 1.
9569 * decl.c (pop_decl_level): Removed; manually inlined.

9591 with destructor names when either NO_DOLLAR_IN_LABEL or

9597 with actual types in complex type as well.
9598 (coerce_template_parms): update the grok_template_type ()

9606 * typeck2.c (store_init_value): Don't abort when called to
9607 initialize a type that needs constructing with a CONSTRUCTOR.

9616 resolves_to_fixed_type_p to determine if the virtual bases are in
9617 their right place for the type of expr. Cures problem of thinking a
9618 virtual base class is one place, when it is in fact someplace else.

9622 * init.c (resolve_offset_ref): Make sure we first convert to
9623 intermediate type, if given, when dealing with members off `this'.

10885 (finish_base_struct): Update no_const_asn_ref, note that you should
10886 update cant_synth_*, propagate TYPE_GETS_ASSIGN_REF.
10887 (finish_struct): Add decls for cant_synth_*, no_const_asn_ref, and
10888 initialize them properly. Set no_const_asn_ref properly. Set
10889 cant_synth_* in some of the situations where they should be set.
10890 Propagate TYPE_GETS_ASSIGN_REF. Use cant_synth_copy_ctor. Add call
10891 to cons_up_default_function for operator=.

10896 to member function types.
10897 * cp-typeck.c (build_ptrmemfunc): Add FORCE parameter to indicate

10908 * cp-decl.c (grok_op_properties): Set TYPE_HAS_ASSIGN_REF
10909 and its kin properly.

10914 * cp-method.c (build_opfncall): Don't count pointer to member
10915 functions as aggregates here, as we don't want to look up methods in
10916 them. The compiler would core dump if we did, as they don't have
10918 * cp-typeck.c (build_indirect_ref): Improve wording on error

10923 * cp-decl.c (grok_op_properties): Allow operator?: with pedwarn
10924 (since it's supported in other compiler bits).
10926 * cp-method.c (report_type_mismatch): Use cp_error; ignore err_name
10929 * cp-error.c (dump_function_decl): Don't print return type for
10930 constructors and destructors.
10932 * cp-cvt.c (cp_convert_to_pointer): Import code from
10933 convert_to_pointer so we can return error_mark_node in the case of an
10934 error, and to allow more meaningful error messages.
10935 (build_type_conversion): Don't go through void* when trying
10936 to convert to a pointer type.
10938 * cp-decl.c (grokfndecl): Move call to grok_op_properties back
10939 after grokclassfn so that it's dealing with the right decl.
10940 (grok_op_properties): Don't assert !methodp for op new and op delete.
10942 * cp-init.c (build_delete): Don't use TYPE_BUILT_IN (there are now
10943 no uses of it in the compiler).
10945 * cp-call.c (build_scoped_method_call): Fix for destructors of simple
10947 (build_method_call): Ditto.

10957 intermediate stage of compiling C++ source.
10959 Fri Nov 19 11:26:09 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
10961 * cp-expr.c (cplus_expand_expr): Make call_target a valid memory
10962 address before using it, so it can be later safely compared.
10964 Fri Nov 12 15:30:27 1993 Jason Merrill (jason@deneb.cygnus.com)
10966 * cp-pt.c (tsubst): Deal with new overloading.
10968 * cp-typeck.c (fntype_p): is the arg function type?
10969 (comp_target_parms): pedwarn on conversion from (anything) to (...).
10970 (build_x_function_call): Deal with new overloading.
10972 * cp-tree.c (decl_list_length): Deal with new overloading.
10973 (decl_value_member): Like value_member, but for DECL_CHAINs.
10975 * cp-decl.c (duplicate_decls): Deal with new overloading.
10976 (start_decl): Ditto.
10978 * cp-class.c (instantiate_type): Deal with new overloading.
10980 * cp-call.c (convert_harshness_ansi): Deal with new overloading.
10981 (convert_harshness_old): Deal with new overloading.
10982 (build_overload_call_real): Ditto.
10984 Mon Nov 8 13:50:49 1993 Jason Merrill (jason@deneb.cygnus.com)
10986 * cp-tree.c (get_unique_fn): New function; returns FUNCTION_DECL
10987 if unambiguous, NULL_TREE otherwise.
10988 (get_first_fn): Returns the first appropriate FUNCTION_DECL.
10989 (is_overloaded_fn): Returns whether or not the passed tree is
10990 a function or list of functions.
10992 * cp-init.c (init_init_processing): use `get_first_fn' to find
10993 the FUNCTION_DEFN for new and delete.
10995 * cp-decl.c (push_overloaded_decl): Use new overloading strategy, cut
10996 code size in half (I spit on special cases).
10998 Tue Sep 7 20:03:33 1993 Jason Merrill (jason@deneb.cygnus.com)
11000 * cp-decl.c: Allow references and template type parameters as well
