1057 (build_eh_type_type): New routine.
1058 (expand_start_catch_block): Use build_eh_type_type, as we never want
1059 the dynamic type of the catch parameter, just the static type.
1060 Fixes core dumps when -frtti is used and one catchs pointers to
1063 Thu Aug 10 14:55:29 1995 Mike Stump <mrs@cygnus.com>
1065 * except.c (expand_builtin_throw): Since we now use normal calling
1066 conventions for __throw, we have to remove the first layer off the
1067 stack, so that the next context we search for handlers is the outer
1068 context instead of the context that had the call to __throw, if we
1069 don't immediately find the desired context.

1096 instead use a SYMBOL_REF, this is so that we don't use LABEL_REFs in
1097 other functions that don't really appear in those functions. This
1098 solves a problem where cc1plus consumed exponential amounts of
1099 memory when -Wall was used.

1144 InsnSave. Also, numerous speed improvements, and correctness
1145 improvements. Double faulting in all situations should now be
1147 (expand_start_all_catch): Instead of having many terminate protected
1148 regions, just have one.
1149 (expand_start_catch_block): No longer have to protect
1150 false_label_rtx, as it isn't used for EH region marking.
1151 (expand_end_catch_block): Expand out EH cleanups here by using
1152 expand_leftover_cleanups.
1153 (expand_end_all_catch): Use sequences instead of playing with insn
1155 (expand_exception_blocks): Ditto. Also protect all catch clauses
1156 with one terminate region.

1211 * tree.def (UNSAVE_EXPR): New tree code.
1212 * typeck.c (c_expand_return): Move goto/return code up inside

1614 instead of DECL_CLASS_CONTEXT for calculating the vfield offset so
1615 abstract virtual functions are handled correctly.
1617 * sig.c (build_signature_table_constructor): Store the correct
1618 delta in signature table entries. It does not yet work for
1619 classes with virtual base classes as implementations of signatures.
1620 (build_signature_method_call): Add the delta to the object_ptr
1621 before generating the function call.
1623 * call.c (build_method_call): Make instance_ptr the signature

1634 message that said we can't handle multiple inheritance for
1635 implementations of signatures
1636 (build_signature_method_call): Use the offset from the sigtable
1637 entry instead of the vptr field from the signature pointer for

1641 call this function anymore from build_signature_method_call.

1660 the way digest_init does, digest_init can't handle initializing an

1663 delta field to get the vtable index.

1672 hold the identifiers for the sigtable fields tag and offset.
1673 (init_decl_processing): Initialize these variables.
1674 (init_decl_processing): Use these variables to build the
1675 sigtable_entry_type structure. Rename the code and offset fields
1676 to tag and delta, respectively; add offset and index fields. Changed
1677 types of fields from short_integer_type_node to delta_type_node.
1678 * sig.c (build_signature_table_constructor): Rename code and offset
1679 to tag and delta, respectively.

1694 among all instantiations, we have to substitute in the real types
1695 in TREE_TYPE (parm).
1696 pt.c (coerce_template_parms): Ditto.
1697 (push_template_decls): Ditto.
1698 (grok_template_type): Deleted as template parameters are shared

3455 here, rather than from xref_defn_tag.
3457 * parse.y (do_xref): Lose.
3458 (named_class_head): If we see 'class foo:' we know it's a
3459 definition, so don't worry about base lists for non-definitions.
3461 * pt.c (push_template_decls): Template parm decls are artificial.
3463 * decl.c (duplicate_decls): Restore check for qualifier
3464 disagreement for non-functions.

3520 (finish_file): Move finish_prevtable_vardecl up to before the global
3521 initializers are done as tdecls are initialized in the global
3522 initializer. Also Pick up any new tdecls or vtables needed by
3523 synthesized methods.
3525 * class.c (finish_struct): Simplify. We have to do rtti scanning at
3526 end, so we might as well do all of it there.

3530 * call.c (build_method_call): Fix -fthis-is-variable for 32-bit

3539 in finish_prevtable_vardecl.
3540 * decl2.c (finish_file): Call finish_prevtable_vardecl.
3541 * gc.c (build_generic_desc): Allow it to be called when not at the
3542 global binding layer, but behave as if we were.
3543 (build_t_desc): Rearrange a bit so that it really works and is
3545 * class.c (finish_struct): Don't decide on tdecls here, as we have
3546 to wait until the end of the file in general to decide whether or
3549 Mon Jan 30 01:00:40 1995 Jason Merrill <jason@phydeaux.cygnus.com>

3559 * call.c (build_method_call): Ditto.
3561 * call.c (convert_harshness): Make conversion from a pointer to bool

3578 Sat Jan 28 09:10:44 1995 Mike Stump <mrs@cygnus.com>
3580 * decl2.c (finish_vtable_vardecl): Now set the
3581 interface/implementation of vtables on the first virtual function,
3582 if one exists, otherwise we use the old method. This is a major win
3583 in terms of cutting down the size of objects and executables in
3584 terms of text space and data space. Now most of the savings that
3585 #pragma interface/implementation gives is automatic in a fair number

3590 * decl.c (grokdeclarator): Discard the template parameters in a

3604 * parse.y: Add END_OF_LINE token.
3606 * lex.c (check_newline): Set linemode when we see a # directive, and
3607 unset it when we're done. Turn all 'return's into 'goto skipline'.
3608 Fix all uses of '\n', since we won't see it anymore. Put back the
3609 character we read before checking for a sysv or target pragma.
3610 (real_yylex): If we see an EOF in linemode, return END_OF_LINE.
3611 (handle_sysv_pragma): Don't look at the input stream; quit when we
3612 see an END_OF_LINE token.

3637 * class.c (instantiate_type): Change error message text.

3640 Mon Jan 23 21:57:14 1995 Mike Stump <mrs@cygnus.com>
3642 * pt.c (tsubst): When we copy a node, don't forget to copy
3643 TREE_CHAIN, we use it later.

7365 * class.c (finish_struct): It is legal for a class with no
7366 constructors to have nonstatic const and reference members.
7368 Thu Apr 14 07:15:11 1994 Brendan Kehoe (brendan@lisa.cygnus.com)
7370 * decl.c (push_overloaded_decl): Avoid giving errors about
7371 built-ins, since duplicate_decls will have given warnings/errors
7374 Thu Apr 14 03:45:12 1994 Jason Merrill (jason@deneb.cygnus.com)
7376 * cvt.c (convert_to_reference): Warn about casting pointer type to
7377 reference type when this is probably not what they wanted.
7379 Wed Apr 13 13:12:35 1994 Per Bothner (bothner@kalessin.cygnus.com)
7381 * decl.c (finish_decl): Don't mindlessly set TREE_USED for
7382 static consts any more (toplev.c has now been modified to
7383 not emit warnings if they are unused).
7385 Wed Apr 13 00:22:35 1994 Jason Merrill (jason@deneb.cygnus.com)
7387 * decl.c (grok_op_properties): If op new/delete get here with
7388 METHOD_TYPEs, do a revert_static_member_fn.
7390 * cp-tree.h (IDENTIFIER_CLASS_TYPE_VALUE): Lose.
7391 * init.c (is_aggr_typedef): Don't look at
7392 IDENTIFIER_CLASS_TYPE_VALUE.
7393 (get_aggr_from_typedef): Ditto.
7394 (get_type_value): Ditto.
7395 * call.c (build_scoped_method_call): Don't rely on overloaded
7396 template names having IDENTIFIER_CLASS_VALUE set.
7398 * parse.y (component_decl_1, fn.def2): Revert rules for
7400 (component_decl_1, fn.def2): Use $1 instead of $$, since $$ is being
7403 * decl.c (start_function): Only warn about `void main()' if pedantic
7404 || warn_return_type.
7406 Tue Apr 12 02:14:17 1994 Jason Merrill (jason@deneb.cygnus.com)
7408 Clean up overloading of the template name.
7409 * class.c (pushclass): overload the template name whenever pushing
7410 into the scope of a template class, not just if it is
7412 (popclass): Correspondingly.
7413 * search.c (push_class_decls): Don't overload_template_name.
7414 * pt.c (overload_template_name): Don't set IDENTIFIER_LOCAL_VALUE or
7415 DECL_CONTEXT on things.
7416 * parse.y (left_curly): Don't overload_template_name.
7417 * class.c (finish_struct): Don't undo_template_name_overload.
7419 * method.c (build_opfncall): Only pass one argument to global op
7422 * call.c (build_method_call): Use TYPE_VEC_DELETE_TAKES_SIZE to
7423 decide how many arguments to use for vec delete.
7425 * decl.c (grok_op_properties): Be consistent in modifying
7427 (grokdeclarator): Only complain about function decls with no return
7428 type if we're being pedantic.
7430 Mon Apr 11 00:10:53 1994 Jason Merrill (jason@deneb.cygnus.com)
7432 Add support for operator new [] and operator delete [].
7434 * tree.def: Add VEC_NEW_EXPR and VEC_DELETE_EXPR.
7435 * ptree.c (print_lang_type): Indicate vec new/delete.
7436 * parse.y: Support vec new/delete.
7437 * method.c (build_decl_overload): Deal with vec new/delete.
7438 (build_opfncall): Ditto.
7439 * lex.c (init_lex): Set up values of ansi_opname and opname_tab for
7440 vec new/delete. vec new uses "__vn", and vec delete uses "__vd".
7441 * init.c (init_init_processing): Set up BIVN and BIVD.
7442 (do_friend): Don't clean up after mistaken setting of TREE_GETS_NEW,
7443 since it doesn't happen any more.
7444 (build_new): Support vec new. Always call something.
7445 (build_x_delete): Support vec delete.
7446 (build_vec_delete): Lose dtor_dummy argument, add use_global_delete,
7447 and pass it to build_x_delete.
7448 * decl2.c (delete_sanity): Don't change behavior by whether or not
7449 the type has a destructor. Pass use_global_delete to
7451 (coerce_delete_type): Make sure that the type returned has a first
7452 argument of ptr_type_node.
7453 * decl.c (init_decl_processing): Also declare the global vec
7455 (grokdeclarator): Also force vec new/delete to be static.
7456 (grok_op_properties): Note presence of vec new/delete, and play with
7457 their args. If vec delete takes the optional size_t argument, set
7458 TYPE_VEC_DELETE_TAKES_SIZE.
7459 * cp-tree.h (TYPE_GETS_{REG,VEC}_DELETE): New macros to simplify
7460 checking for one delete or the other.
7461 (lang_type): gets_new and gets_delete are now two bits long. The
7462 low bit is for the non-array version. Lose gets_placed_new.
7463 (TYPE_VEC_DELETE_TAKES_SIZE): New macro indicating that the vec
7464 delete defined by this class wants to know how much space it is
7466 (TYPE_VEC_NEW_USES_COOKIE): New macro to indicate when vec new must
7467 add a header containing the number of elements in the vector; i.e.
7468 when the elements need to be destroyed or vec delete wants to know
7470 * class.c (finish_struct_methods): Also check for overloading vec
7472 * call.c (build_method_call): Also delete second argument for vec
7475 * decl.c (grokdeclarator): Correct complaints again.
7476 (grokdeclarator): Fix segfault on null declarator.
7477 (decls_match): Also accept redeclaration with no arguments if both
7478 declarations were in C context. Bash TREE_TYPE (newdecl) here.
7479 (duplicate_decls): Instead of here.
7481 * parse.y (nested_name_specifier_1): Lose rules for dealing with
7482 syntax errors nicely, since they break parsing of 'const i;'.
7484 * decl.c (lookup_name): if (got_scope == current_class_type)
7485 val = IDENTIFIER_CLASS_VALUE (name).
7487 * search.c (lookup_nested_tag): Look in enclosing classes, too.
7489 * spew.c (yylex): Only look one character ahead when checking for a
7492 * lex.c (check_newline): Read first nonwhite char before
7493 incrementing lineno.
7495 * decl.c (grokdeclarator): Don't claim that typedefs are variables
7498 * parse.y: Divide up uses of unqualified_id into
7499 notype_unqualified_id and unqualified_id, so that TYPENAME can be
7500 used as an identifier after an object.
7502 * class.c (push_nested_class): Don't push into non-class scope.
7504 * decl.c (grokdeclarator): If an identifier could be a type
7505 conversion operator, but has no associated type, it's not a type
7506 conversion operator.
7508 * pt.c (unify): Check for equality of constants better.
7510 * decl.c (grokdeclarator): Don't complain about access decls.
7512 Sun Apr 10 02:39:55 1994 Jason Merrill (jason@deneb.cygnus.com)
7514 * decl.c (grokdeclarator): pedwarn about data definitions without
7517 * parse.y (datadef): Don't pedwarn about decls without types here,
7518 since that is valid for functions.
7519 (fn.def2, component_decl): Support constructors with declmods again.
7520 (nomods_initdecls): For decls without any mods, so that we don't try
7521 to get declspecs from some arbitrary $0.
7523 * search.c (lookup_field): Use cp_error.
7525 * parse.y (nested_name_specifier_1): Don't check aggr/non-aggr type
7526 here; it breaks destructors for non-aggr types.
7528 * decl.c (lookup_name): Only look for TYPE_DECLs in base classes of
7529 a type being defined, like the comment says.
7530 If got_scope is not an aggregate, just return NULL_TREE.
7532 * pt.c (create_nested_upt): Kung's code for creating types nested
7533 within uninstantiated templates now lives here (it used to live in
7534 hack_more_ids). It needs to be expanded.
7536 * parse.y: Stop calling see_typename so much.
7538 * decl.c (lookup_name): Deal with TTPs and UPTs.
7540 * lex.c (real_yylex): Don't set looking_for_typename just because we
7542 (dont_see_typename): #if 0 out.
7544 * spew.c (yylex): Increment looking_for_typename if the next
7545 character is SCOPE, rather than setting it to 1; this way, the value
7546 from seeing an aggr specifier will not be lost. This kinda relies
7547 on looking_for_typename never being < 0, which is now true.
7549 * parse.y (nested_name_specifier_1): Accept TEMPLATE_TYPE_PARMs,
7551 (named_class_head_sans_basetype): Accept template types, too. Oops.
7553 Fri Apr 8 16:39:35 1994 Jason Merrill (jason@deneb.cygnus.com)
7555 * decl2.c (reparse_decl_as_expr1): Handle SCOPE_REFs.
7557 * parse.y: Lose START_DECLARATOR.
7559 * search.c (lookup_nested_tag): New function to scan CLASSTYPE_TAGS
7562 * parse.y: Simplify fn.def2 and component_decl. Support 'enum
7563 A::foo' syntax. Catch invalid scopes better.
7565 * parse.y, lex.c: lose TYPENAME_COLON.
7567 * decl2.c (groktypefield): #if 0 out.
7569 * decl.c (lookup_name): If the type denoted by got_scope is
7570 currently being defined, look in CLASSTYPE_TAGS rather than FIELDS.
7572 * class.c (push_nested_class): Don't try to push into
7575 Fri Apr 8 07:26:36 1994 Brendan Kehoe (brendan@lisa.cygnus.com)
7577 * Makefile.in (stamp-parse): Update count of conflicts to 33.
7579 Thu Apr 7 17:47:53 1994 Jason Merrill (jason@deneb.cygnus.com)
7581 A saner implementation of nested types that treats template types
7582 no differently from non-template types. There are still some
7583 shortcomings of our system; most notably, it is difficult to look
7584 for a nested type that is hidden by another name, because of the way
7585 we keep track of hidden types. But this shouldn't be a problem for
7586 just about anyone. Perhaps lookup_field should be fixed up a bit.
7588 * spew.c: Moved handling of nested types/scoping from the lexer
7589 into the parser. Removed variable template_type_seen_before_scope.
7590 Removed functions frob_identifier, hack_more_ids, and various cruft
7591 that was #if 0'd out in the past, reducing the size of the file from
7592 1146 lines to 450 lines. We can't quite do away with spew.c yet,
7593 though; we still need it for do_aggr () and checking for SCOPE after
7594 the current identifier. And setting lastiddecl.
7596 * parse.y: Moved handling of nested types/scoping from the lexer
7597 into the parser, using a new global variable `got_scope'. Reduced
7598 the number of states by 53. Implemented all uses of explicit global
7599 scope. Removed terminals SCOPED_TYPENAME and SCOPED_NAME. Removed
7600 nonterminals tmpl.1, scoped_base_class, id_scope, typename_scope,
7601 scoped_typename. Added nonterminals nested_type,
7602 qualified_type_name, complete_type_name, qualified_id, ptr_to_mem,
7603 nested_name_specifier, global_scope, overqualified_id, type_name.
7604 Changed many others. Added 9 new reduce/reduce conflicts, which are
7605 nested type parallels of 9 that were already in the grammar for
7606 non-nested types. Eight of the now 33 conflicts should be removed
7607 in the process of resolving the late binding between variable and
7610 * gxxint.texi (Parser): Update.
7612 * cp-tree.h (IS_AGGR_TYPE_CODE): Add UNINSTANTIATED_P_TYPE.
7614 * lex.h: Add decl for got_scope.
7616 * lex.c (see_typename): Claim to be the lexer when calling
7619 * decl.c (lookup_name): When called from the lexer, look at
7620 got_scope and looking_at_typename; otherwise don't.
7622 Thu Apr 7 22:05:47 1994 Mike Stump <mrs@cygnus.com>
7624 31th Cygnus<->FSF merge.
7626 Thu Apr 7 17:47:53 1994 Jason Merrill (jason@deneb.cygnus.com)
7628 * decl2.c (mark_vtable_entries): Call this to mark all the
7629 entries in the vtable addressable.
7630 (finish_decl_parsing): Handle SCOPE_REFs.
7632 * decl.c (decls_match): Always call compparms with strict == 1.
7633 Handle the special case of C function redecl here.
7634 (duplicate_decls): Only keep the old type if the new decl takes no
7637 * typeck.c (compparms): Also allow t1 to be ... if strict == 0.
7639 Thu Apr 7 16:17:50 1994 Mike Stump <mrs@cygnus.com>
7641 * class.c (build_vtable_entry): Fix breakage introduced Apr 5
7644 Wed Apr 6 16:05:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
7646 * init.c (build_virtual_init), search.c (build_vbase_vtables_init),
7647 ch-tree.h: Every place these functions were called, the result was
7648 immediately passed to expand_expr_stmt. Reduce redundancy by
7649 calling expand_expr_init *inside* these functions. These
7650 makes for a simpler interface, and we don't have to build
7651 compound expressions. Hence, rename these function to:
7652 expand_virtual_init and expand_vbase_vtables_init respectively.
7653 * init.c, decl.c: Change callers of these functions.
7654 * init.c, cp-tree.h (expand_virtual_init): Make static.
7656 * decl2.c (finish_file): Check TREE_PUBLIC||TREE_ADDRESSABLE
7657 rather than DECL_SAVED_INSNS before emitting inlines.
7659 Wed Apr 6 13:06:39 1994 Jason Merrill (jason@deneb.cygnus.com)
7661 * spew.c (init_spew): #if 0 out stuff used by arbitrate_lookup.
7663 * decl.c (duplicate_decls): If this is a new declaration of an
7664 extern "C" function, keep the type (for the argtypes).
7665 (redeclaration_error_message): Don't check DECL_LANGUAGE here.
7666 (decls_match): Call compparms with a value of strict dependent on
7667 the value of strict_prototypes for DECL_LANGUAGE (oldecl).
7669 * typeck.c (compparms): ... is only equivalent to non-promoting
7670 parms if we're not being strict.
7672 * parse.y (empty_parms): Don't check flag_ansi || pedantic here.
7674 * decl.c (init_decl_processing): if (flag_ansi || pedantic)
7675 strict_prototypes_lang_c = strict_prototypes_lang_cplusplus;
7677 * decl2.c (grok_function_init): Don't set DECL_INITIAL on pure

7684 * cp-tree.h (FNADDR_FROM_VTABLE_ENTRY), tree.c
7685 (fnaddr_from_vtable_entry): Handle flag_vtable_thunks case.
7686 * cp-tree.h (memptr_type): New variable.
7687 * class.c (build_vtable_entry): Build thunk if necessary.
7688 * class.c (build_vfn_ref): If using thunks, don't need
7689 to add delta field from vtable (there is none!).
7690 * decl.c: Add memptr_type as well as vtable_entry_type.
7691 If using thunks, the latter is just ptr_type_node.
7692 * gc.c, typeck.c: Use memptr_typeChange, not vtable_entry_type.
7693 * decl2.c (finish_vtable_vardecl): Handle thunks.
7694 * expr.c (cplus_expand_expr): Support THUNK_DECL.
7696 * decl.c (grokdeclarator): Set DECL_THIS_EXTERN if "extern".
7697 * decl.c (start_function): Set current_extern_inline based on
7698 DECL_THIS_EXTERN, not TREE_PUBLIC.
7699 * decl.c (finish_function): Call mark_inline_for_output if needed,
7701 Improve intelligence about when to emit inlines.
7702 * cp-tree.h (lang_decl_flags): New field saved_inline.
7703 * cp-tree.h (DECL_SAVED_INLINE): New macro.
7704 * class.c (add_virtual_function): Don't set TREE_ADDRESSABLE.
7705 * decl.h, decl.c (pending_addressable_inlines): Removed.
7706 * decl2.c (pending_addressable_inlines): Renamed to saved_inlines.
7707 * decl2.c (mark_inline_for_output): Do nothing if
7708 DECL_SAVED_INLINE; otherwise set it (and add to saved_inlines list).
7709 * decl2.c (finish_vtable_vardecl): SET_CLASSTYPE_INTERFACE_KNOWN
7710 and set CLASSTYPE_INTERFACE_ONLY if there is a non-inline virtual.
7711 * decl2.c (finish_file): Writing out inlines later, so we can
7712 also handle the ones needed for vtbales.
7713 * decl2.c (write_vtable_entries, finish_vtable_typedecl): Removed.
7715 * cp-tree.h, class.c, decl2.c, search.c: Remove -fvtable-hack
7716 and flag_vtable_hack. Use -fvtable-thunks and flag_vtable_thunks
7717 instead. (The rationale is that these optimizations both break binary
7718 compatibility, but should become the default in a future release.)
7720 Wed Apr 6 10:53:56 1994 Mike Stump <mrs@cygnus.com>
7722 * class.c (modify_vtable_entries): Never reset the DECL_CONTEXT
7723 of a fndecl, as we might not be from that vfield.
7725 Tue Apr 5 17:43:35 1994 Kung Hsu (kung@mexican.cygnus.com)
7727 * class.c (add_virtual_function): fix bug for pure virtual, so
7728 that DECL_VINDEX of the dummy decl copied won't be error.
7729 (see also Apr 4 change)
7731 Tue Apr 5 17:23:45 1994 Per Bothner (bothner@kalessin.cygnus.com)
7733 * typeck.c (c_expand_return): Before checking that we're not
7734 returning the address of a local, make sure it's a VAR_DECL.
7735 (And don't worry about it being a TREE_LIST.)
7737 Tue Apr 5 13:26:42 1994 Jason Merrill (jason@deneb.cygnus.com)
7739 * parse.y (YYDEBUG): Always define.
7740 * lex.c (YYDEBUG): Ditto.
7742 Mon Apr 4 11:28:17 1994 Kung Hsu (kung@mexican.cygnus.com)
7744 * class.c (finish_struct): backup out the change below, put the
7745 new change for the same purpose. The change below breaks code.
7747 * class.c (finish_struct): if pure virtual, copy node and make
7748 RTL point to abort, then put in virtual table.
7749 * decl2.c (grok_function_iit): reinstate Mar 31 change.
7751 Sat Apr 2 03:12:58 1994 Jason Merrill (jason@deneb.cygnus.com)
7753 * init.c (build_new): pedwarn about newing const and volatile
7756 * tree.c (get_identifier_list): Only do the special handling
7757 thing if we're dealing with the main variant of the record type.
7759 * cvt.c (convert_to_reference): When converting between
7760 compatible reference types, use the pointer conversion machinery.
7761 Don't just blindly overwrite the old type.
7763 Fri Apr 1 17:14:42 1994 Jason Merrill (jason@deneb.cygnus.com)
7765 * call.c (build_method_call): When looking at global functions,
7766 be sure to use instance_ptr for the first argument, not some version
7767 of it that has been cast to a base class. Also do this before
7768 comparing candidates.
7770 Thu Mar 31 19:50:35 1994 Jason Merrill (jason@deneb.cygnus.com)
7772 * call.c (build_method_call): Constructors can be called for
7775 Thu Mar 31 16:20:16 1994 Kung Hsu (kung@mexican.cygnus.com)
7777 * decl2.c (grok_func_init): do not abort as rtl for pur virtual
7778 fucntions. They can be defined somewhere else.

7782 * decl.c (init_decl_processing): Declare __builtin_return_address
7783 and __builtin_frame_address for C++ as well.
7785 Thu Mar 31 12:35:49 1994 Mike Stump <mrs@cygnus.com>
7787 * typeck2.c (store_init_value): Integral constant variables are
7788 always constant, even when doing -fpic.

7792 * decl.c (redeclaration_error_message): Pass the types to
7795 Wed Mar 30 21:29:25 1994 Mike Stump <mrs@cygnus.com>
7797 Cures incorrect errors about pure virtuals in a class, when they
7798 have been overridden in a derived class.
7800 * search.c (get_abstract_virtuals): Reimplement.
7801 * search.c (get_abstract_virtuals_1): New routine.
7803 Wed Mar 30 14:10:04 1994 Jason Merrill (jason@deneb.cygnus.com)
7805 * pt.c (push_template_decls): Make the pushed level pseudo
7808 * parse.y (extdefs): Don't pop everything if the current binding
7809 level is pseudo_global.
7811 * decl.c (pop_everything): Stop on reaching a pseudo-global
7814 * cp-tree.h (DECL_FUNCTION_MEMBER_P): Change to more reliable test.
7816 * decl.c (duplicate_decls): Only copy DECL_SOURCE_{FILE_LINE} if
7817 the old decl actually had an initializer.
7819 * {various}: Clean up gcc -W complaints.
7821 * cp-tree.h (DECL_FUNCTION_MEMBER_P): Currently defined to be
7822 (DECL_CONTEXT (NODE) != NULL_TREE).
7824 * parse.y (lang_extdef): Call pop_everything if necessary.
7826 * decl.c (pop_everything): New function for popping binding
7827 levels left over after a syntax error.
7828 (pushdecl): Use DECL_FUNCTION_MEMBER_P to decide whether or not
7829 a function is a member.
7831 Wed Mar 30 14:20:50 1994 Mike Stump <mrs@cygnus.com>
7833 Cures calling a more base base class function, when a more derived
7834 base class member should be called in some MI situations.
7836 * search.c (make_binfo): Use more the more specialized base
7837 binfos from the binfo given as the second argument to make_binfo,
7838 instead of the unspecialized ones from the TYPE_BINFO.

7841 * tree.c (propagate_binfo_offsets, layout_vbasetypes): Ditto.

7847 * decl.c (pushdecl): If pushing a C-linkage function, only do a
7848 push_overloaded_decl.

7887 * decl.c (start_method): Methods defined in the class body are
7888 inline whether or not it's a template class.

8060 * decl.c (grokdeclarator): Set TREE_PUBLIC for METHOD_TYPE
8061 in FIELD context, when appropriate. Also,
8062 CLASSTYPE_INTERFACE_ONLY is irrelevant to setting TREE_PUBLIC.

8067 * parse.y (after_type_declarator1): Expand type_quals.

8091 (pop_from_top_level): Restore them.
8093 * gxxint.texi (Parser): Update.
8095 These two patches finish moving the task of expr/declarator
8096 ambiguity resolution from the lexer to the parser, and add one more

8099 * parse.y (decl): Add "direct_" in typespec X rules.
8100 (direct_declarator): New nonterminal for

8106 * spew.c (yylex): #if 0 out START_DECLARATOR insertion.
8108 These two patches disable some excessive cleverness on the part of
8109 g++; a non-class declaration always hides a class declaration in the
8110 same scope, and g++ was trying to unhide it depending on the
8111 enclosing expression.
8113 * spew.c (arbitrate_lookup): #if 0 out.
8115 * decl.c (lookup_name): Never call arbitrate_lookup.
8117 * parse.y (complex_notype_declarator1): Add '*'

8127 These changes fix the compiler's handling of the functional cast/
8128 object declaration ambiguities in section 6.8 of the ARM. They also
8129 add 11 reduce/reduce conflicts. Sigh.

8141 an expr_or_declarator.
8142 (complex_direct_notype_declarator): A direct_notype_declarator that
8143 doesn't conflict with expr_or_declarator. Use
8144 notype_unqualified_id. Remove id_scope see_typename TYPENAME rule.
8145 (functional_cast): New nonterminal, for the three functional cast
8146 rules. So that they can be moved after
8147 complex_direct_notype_declarator.
8148 (see_typename): Don't accept type_quals any more.
8150 * decl2.c (reparse_decl_as_expr): New function to deal with parse
8151 nodes for code like `int (*a)++;'.
8152 (reparse_decl_as_expr1): Recursive subroutine of the above.
8153 (finish_decl_parsing): New function to deal with parse nodes for
8154 code like `int (*a);'. See the difference?
8156 Thu Mar 17 12:16:10 1994 Mike Stump <mrs@cygnus.com>
8158 These changes break binary compatibility in code with classes
8159 that use virtual bases.

8162 sure virtual bases are initialized in dfs ordering.
8163 * search.c (get_vbase_types): Simplify and make readable.
8165 Thu Mar 17 12:01:10 1994 Jason Merrill (jason@deneb.cygnus.com)

8178 Wed Mar 16 17:43:07 1994 Jason Merrill (jason@deneb.cygnus.com)
8180 * parse.y (direct_notype_declarator): Add PTYPENAME rule, remove
8181 all of the scoped PTYPENAME rules.
8183 Wed Mar 16 16:39:02 1994 Mike Stump <mrs@cygnus.com>
8185 * init.c (build_offset_ref): The value of A::typedef_name is
8186 always the TYPE_DECL, and never an error.
8188 Tue Mar 15 20:02:35 1994 Jason Merrill (jason@deneb.cygnus.com)
8190 * search.c (get_base_distance_recursive): Two binfos can only
8191 represent the same object if they are both via_virtual.
8193 * class.c (finish_base_struct): Check vbases for ambiguity, too.
8195 * search.c (get_vbase_types): Accept binfo argument, too.
8197 Tue Mar 15 19:22:05 1994 Kung Hsu (kung@mexican.cygnus.com)
8199 * decl.c (complete_array_type): complete TYPE_DOMAIN of the
8200 initializer also, because back-end requires it.
8202 Tue Mar 15 15:33:31 1994 Jason Merrill (jason@deneb.cygnus.com)
8204 * error.c (dump_expr): Support member functions (which show up as

8254 * decl2.c (reparse_decl_as_expr): Recursive function to change
8255 parse nodes for `A()()' from "function returning function returning

8286 op= problems with virtual inheritance.

8346 direct_after_type_declarator, direct_abstract_declarator): Split up

8366 * parse.y (typed_declspecs, declmods): It's not necessary to hash

8368 can reduce to typed_declspecs.
8370 Wed Mar 2 14:29:18 1994 Jason Merrill (jason@cygnus.com)
8372 * cvt.c (build_up_reference): If we aren't checking visibility,
8373 also allow base->derived conversions.

8411 * lex.c (check_newline): #pragma interface can take a string
8412 argument, just like #pragma implementation. #pragma implementation
8413 checks for garbage on the line, line #pragma interface does. Main
8414 input files do not auto implement like named files, #pragma
8415 implementation must be used explicitly.

8429 * Makefile.in (stamp-parse): Update expected conflict count.
8431 * parse.y (various): Replace "declmods declarator" with "declmods
8432 notype_declarator". The comment saying that "declmods declarator ';'"
8433 corresponds to "int i;" was wrong; it corresponds to "const i;".
8434 (component_decl): Add "typed_declspecs declarator ';'" rule; this
8435 *does* correspond to "int i;". Change "declmods components" to
8436 "declmods notype_components".
8437 (components): Don't deal with a list of one anymore.
8438 (notype_components): New nonterminal, corresponds to notype_declarator.

8481 that we are calling ourselves recursively, so a partial match is OK.
8482 (unify): Support pointers to methods and functions.
8483 (tsubst): Support method pointers.
8484 * decl.c (build_ptrmemfunc_type): No longer static, so that

8494 * pt.c (do_function_instantiation): Ditto.
8495 * class.c (instantiate_type): Ditto.

8518 * typeck.c (convert_for_initialization): Remove bogus warning.

8524 * class.c (build_vfn_ref): Cast delta field to ptrdiff_type_node,

8529 * decl.c (build_ptrmemfunc_type): Make sure that the pmf type
8530 goes onto the same obstack as its target type.

8534 * cvt.c (convert_to_reference): If converting via constructor
8535 on local level, go back to build_cplus_new approach.
8537 * tree.c (build_cplus_new): If with_cleanup_p, set cleanup slot
8538 to error_mark_node to prevent expand_expr from building a cleanup
8541 * lex.c (default_assign_ref_body): Return *this from the memcpy
8544 * decl.c (grok_reference_init): Just return if called with
8545 error_mark_node, don't worry about initializing non-const reference
8548 * cvt.c (convert_to_reference): Do the right thing for
8549 non-aggregate reference conversions, pedwarn when generating a
8550 non-const reference to a temporary.
8552 * class.c (finish_struct): TYPE_HAS_COMPLEX_{INIT,ASSIGN}_REF and
8553 TYPE_NEEDS_CONSTRUCTING all depend on TYPE_USES_VIRTUAL_BASECLASSES

8558 * decl.c (grok_reference_init): Pawn off a lot of the work on
8559 convert_to_reference. Generally do the right thing.
8561 * cvt.c (convert_to_reference): Conform to the initial comment;
8562 i.e. don't create temps if decl != error_mark_node. Handle
8563 cleanups better for temps that do get created. Don't pretend
8564 that we can use an 'A' to initialize a 'const double &' just by
8565 tacking on a NOP_EXPR. Support LOOKUP_SPECULATIVELY.
8567 * call.c (build_method_call): Set TREE_HAS_CONSTRUCTOR on

8579 (which isn't always the inner_binding_level).
8581 * cvt.c (build_up_reference): Don't ever call expand_aggr_init.
8582 It's ugly, and I don't think it's the right thing to do.
8584 * cp-tree.h, class.c, decl.c, decl2.c, sp/search.c:
8585 Remove NEW_CLASS_SCOPING, assuming it is always 1.
8586 * decl.c (pop_decl_level): Removed; manually inlined.

8608 with destructor names when either NO_DOLLAR_IN_LABEL or

8614 with actual types in complex type as well.
8615 (coerce_template_parms): update the grok_template_type ()

8623 * typeck2.c (store_init_value): Don't abort when called to
8624 initialize a type that needs constructing with a CONSTRUCTOR.

8633 resolves_to_fixed_type_p to determine if the virtual bases are in
8634 their right place for the type of expr. Cures problem of thinking a
8635 virtual base class is one place, when it is in fact someplace else.

8639 * init.c (resolve_offset_ref): Make sure we first convert to
8640 intermediate type, if given, when dealing with members off `this'.

9539 (finish_struct): Ditto. Well, nigh-correctly; it won't deal
9540 properly with the case where a class contains an object of an

9600 * cp-call.c (convert_harshness_ansi): When the parm isn't an lvalue,
9601 only go for setting TRIVIAL_CODE if we are dealing with types that

9868 (build_method_call): When we had some candidates, but didn't get a
9869 usable match, don't report that we got an error with the first
9870 candidate. Instead, say there were no matches, and list the
9871 candidates with print_candidates. In the second pass, make sure we
9872 clear out ever_seen, so we can accurately count the number of

9943 * cp-method.c (report_type_mismatch): Use cp_error; ignore err_name
9946 * cp-error.c (dump_function_decl): Don't print return type for
9947 constructors and destructors.
9949 * cp-cvt.c (cp_convert_to_pointer): Import code from
9950 convert_to_pointer so we can return error_mark_node in the case of an
9951 error, and to allow more meaningful error messages.
9952 (build_type_conversion): Don't go through void* when trying
9953 to convert to a pointer type.
9955 * cp-decl.c (grokfndecl): Move call to grok_op_properties back
9956 after grokclassfn so that it's dealing with the right decl.
9957 (grok_op_properties): Don't assert !methodp for op new and op delete.
9959 * cp-init.c (build_delete): Don't use TYPE_BUILT_IN (there are now
9960 no uses of it in the compiler).
9962 * cp-call.c (build_scoped_method_call): Fix for destructors of simple
9964 (build_method_call): Ditto.
9966 Fri Nov 19 12:59:38 1993 Jason Merrill (jason@deneb.cygnus.com)
9968 * cp-tree.c (count_functions): Abstraction function.
9970 * cp-call.c (build_overload_call_real): Deal with new overloading
9971 properly, remove dead code.
9973 * gcc.c (default_compilers): Generate and use .ii files in the
9974 intermediate stage of compiling C++ source.
9976 Fri Nov 19 11:26:09 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
9978 * cp-expr.c (cplus_expand_expr): Make call_target a valid memory
9979 address before using it, so it can be later safely compared.
9981 Fri Nov 12 15:30:27 1993 Jason Merrill (jason@deneb.cygnus.com)
9983 * cp-pt.c (tsubst): Deal with new overloading.
9985 * cp-typeck.c (fntype_p): is the arg function type?
9986 (comp_target_parms): pedwarn on conversion from (anything) to (...).
9987 (build_x_function_call): Deal with new overloading.
9989 * cp-tree.c (decl_list_length): Deal with new overloading.
9990 (decl_value_member): Like value_member, but for DECL_CHAINs.
9992 * cp-decl.c (duplicate_decls): Deal with new overloading.
9993 (start_decl): Ditto.
9995 * cp-class.c (instantiate_type): Deal with new overloading.
9997 * cp-call.c (convert_harshness_ansi): Deal with new overloading.
9998 (convert_harshness_old): Deal with new overloading.
9999 (build_overload_call_real): Ditto.
10001 Mon Nov 8 13:50:49 1993 Jason Merrill (jason@deneb.cygnus.com)
10003 * cp-tree.c (get_unique_fn): New function; returns FUNCTION_DECL
10004 if unambiguous, NULL_TREE otherwise.
10005 (get_first_fn): Returns the first appropriate FUNCTION_DECL.
10006 (is_overloaded_fn): Returns whether or not the passed tree is
10007 a function or list of functions.
10009 * cp-init.c (init_init_processing): use `get_first_fn' to find
10010 the FUNCTION_DEFN for new and delete.
10012 * cp-decl.c (push_overloaded_decl): Use new overloading strategy, cut
10013 code size in half (I spit on special cases).
10015 Tue Sep 7 20:03:33 1993 Jason Merrill (jason@deneb.cygnus.com)
10017 * cp-decl.c: Allow references and template type parameters as well
10020 eval: (auto-fill-mode)
