429 rest of the compiler.
430 (get_vtable_entry_n): Ditto.

471 (finish_struct): Ditto.
472 (set_rtti_entry): New routine to update the rtti information at the

487 constructor without an instance.
489 Thu Aug 10 20:00:17 1995 Mike Stump <mrs@cygnus.com>
491 * class.c (prepare_fresh_vtable): Always build the offset to the
492 complete object, as it doesn't cost much. This allows dynamic_cast
493 to void * to work when -frtti isn't given.

506 Thu Aug 10 14:55:29 1995 Mike Stump <mrs@cygnus.com>
508 * except.c (expand_builtin_throw): Since we now use normal calling
509 conventions for __throw, we have to remove the first layer off the
510 stack, so that the next context we search for handlers is the outer
511 context instead of the context that had the call to __throw, if we
512 don't immediately find the desired context.

557 and mutable static objects down, as we might decide during parsing
558 to unset staticp or constp (for example, when const is part of the

587 InsnSave. Also, numerous speed improvements, and correctness
588 improvements. Double faulting in all situations should now be
590 (expand_start_all_catch): Instead of having many terminate protected
591 regions, just have one.
592 (expand_start_catch_block): No longer have to protect
593 false_label_rtx, as it isn't used for EH region marking.
594 (expand_end_catch_block): Expand out EH cleanups here by using
595 expand_leftover_cleanups.
596 (expand_end_all_catch): Use sequences instead of playing with insn
598 (expand_exception_blocks): Ditto. Also protect all catch clauses
599 with one terminate region.

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

1089 * sig.c (build_signature_table_constructor): Use DECL_CONTEXT
1090 instead of DECL_CLASS_CONTEXT for calculating the vfield offset so
1091 abstract virtual functions are handled correctly.
1093 * sig.c (build_signature_table_constructor): Store the correct
1094 delta in signature table entries. It does not yet work for
1095 classes with virtual base classes as implementations of signatures.
1096 (build_signature_method_call): Add the delta to the object_ptr
1097 before generating the function call.
1099 * call.c (build_method_call): Make instance_ptr the signature

1110 message that said we can't handle multiple inheritance for
1111 implementations of signatures

1113 entry instead of the vptr field from the signature pointer for
1114 building a virtual function call.

1117 call this function anymore from build_signature_method_call.

1134 * sig.c (build_signature_table_constructor): Correctly set the

1136 the way digest_init does, digest_init can't handle initializing an
1137 anonymous union inside a struct.

1139 delta field to get the vtable index.
1141 * decl.c (init_decl_processing): Fix number of fields for building

1148 hold the identifiers for the sigtable fields tag and offset.
1149 (init_decl_processing): Initialize these variables.
1150 (init_decl_processing): Use these variables to build the
1151 sigtable_entry_type structure. Rename the code and offset fields
1152 to tag and delta, respectively; add offset and index fields. Changed
1153 types of fields from short_integer_type_node to delta_type_node.

1155 to tag and delta, respectively.
1156 (build_signature_method_call): Ditto. Use above variables.

1189 functionality from build_overload_value so we can reuse it.
1190 (build_overload_value): Handle pointer to member functions as value
1191 parameters for templates.
1192 (build_overload_identifier): Since template parameters are shared

1194 in TREE_TYPE (parm).
1195 pt.c (coerce_template_parms): Ditto.

2904 * parse.y (do_xref): Lose.
2905 (named_class_head): If we see 'class foo:' we know it's a
2906 definition, so don't worry about base lists for non-definitions.
2908 * pt.c (push_template_decls): Template parm decls are artificial.
2910 * decl.c (duplicate_decls): Restore check for qualifier
2911 disagreement for non-functions.

2967 (finish_file): Move finish_prevtable_vardecl up to before the global
2968 initializers are done as tdecls are initialized in the global
2969 initializer. Also Pick up any new tdecls or vtables needed by
2970 synthesized methods.
2972 * class.c (finish_struct): Simplify. We have to do rtti scanning at
2973 end, so we might as well do all of it there.

2977 * call.c (build_method_call): Fix -fthis-is-variable for 32-bit

2986 in finish_prevtable_vardecl.
2987 * decl2.c (finish_file): Call finish_prevtable_vardecl.
2988 * gc.c (build_generic_desc): Allow it to be called when not at the

2990 (build_t_desc): Rearrange a bit so that it really works and is
2992 * class.c (finish_struct): Don't decide on tdecls here, as we have
2993 to wait until the end of the file in general to decide whether or
2996 Mon Jan 30 01:00:40 1995 Jason Merrill <jason@phydeaux.cygnus.com>

3025 Sat Jan 28 09:10:44 1995 Mike Stump <mrs@cygnus.com>
3027 * decl2.c (finish_vtable_vardecl): Now set the
3028 interface/implementation of vtables on the first virtual function,
3029 if one exists, otherwise we use the old method. This is a major win
3030 in terms of cutting down the size of objects and executables in
3031 terms of text space and data space. Now most of the savings that
3032 #pragma interface/implementation gives is automatic in a fair number

3037 * decl.c (grokdeclarator): Discard the template parameters in a

3051 * parse.y: Add END_OF_LINE token.
3053 * lex.c (check_newline): Set linemode when we see a # directive, and
3054 unset it when we're done. Turn all 'return's into 'goto skipline'.
3055 Fix all uses of '\n', since we won't see it anymore. Put back the
3056 character we read before checking for a sysv or target pragma.
3057 (real_yylex): If we see an EOF in linemode, return END_OF_LINE.
3058 (handle_sysv_pragma): Don't look at the input stream; quit when we
3059 see an END_OF_LINE token.

3084 * class.c (instantiate_type): Change error message text.

3089 * pt.c (tsubst): When we copy a node, don't forget to copy

3094 * typeck.c (convert_for_assignment): Initialize variable before use.

6849 * search.c (push_class_decls): Don't overload_template_name.
6850 * pt.c (overload_template_name): Don't set IDENTIFIER_LOCAL_VALUE or
6851 DECL_CONTEXT on things.
6852 * parse.y (left_curly): Don't overload_template_name.
6853 * class.c (finish_struct): Don't undo_template_name_overload.
6855 * method.c (build_opfncall): Only pass one argument to global op
6858 * call.c (build_method_call): Use TYPE_VEC_DELETE_TAKES_SIZE to
6859 decide how many arguments to use for vec delete.
6861 * decl.c (grok_op_properties): Be consistent in modifying
6863 (grokdeclarator): Only complain about function decls with no return
6864 type if we're being pedantic.
6866 Mon Apr 11 00:10:53 1994 Jason Merrill (jason@deneb.cygnus.com)
6868 Add support for operator new [] and operator delete [].
6870 * tree.def: Add VEC_NEW_EXPR and VEC_DELETE_EXPR.
6871 * ptree.c (print_lang_type): Indicate vec new/delete.
6872 * parse.y: Support vec new/delete.
6873 * method.c (build_decl_overload): Deal with vec new/delete.
6874 (build_opfncall): Ditto.
6875 * lex.c (init_lex): Set up values of ansi_opname and opname_tab for
6876 vec new/delete. vec new uses "__vn", and vec delete uses "__vd".
6877 * init.c (init_init_processing): Set up BIVN and BIVD.
6878 (do_friend): Don't clean up after mistaken setting of TREE_GETS_NEW,
6879 since it doesn't happen any more.
6880 (build_new): Support vec new. Always call something.
6881 (build_x_delete): Support vec delete.
6882 (build_vec_delete): Lose dtor_dummy argument, add use_global_delete,
6883 and pass it to build_x_delete.
6884 * decl2.c (delete_sanity): Don't change behavior by whether or not
6885 the type has a destructor. Pass use_global_delete to
6887 (coerce_delete_type): Make sure that the type returned has a first
6888 argument of ptr_type_node.
6889 * decl.c (init_decl_processing): Also declare the global vec
6891 (grokdeclarator): Also force vec new/delete to be static.
6892 (grok_op_properties): Note presence of vec new/delete, and play with
6893 their args. If vec delete takes the optional size_t argument, set
6894 TYPE_VEC_DELETE_TAKES_SIZE.
6895 * cp-tree.h (TYPE_GETS_{REG,VEC}_DELETE): New macros to simplify
6896 checking for one delete or the other.
6897 (lang_type): gets_new and gets_delete are now two bits long. The
6898 low bit is for the non-array version. Lose gets_placed_new.
6899 (TYPE_VEC_DELETE_TAKES_SIZE): New macro indicating that the vec
6900 delete defined by this class wants to know how much space it is
6902 (TYPE_VEC_NEW_USES_COOKIE): New macro to indicate when vec new must
6903 add a header containing the number of elements in the vector; i.e.
6904 when the elements need to be destroyed or vec delete wants to know
6906 * class.c (finish_struct_methods): Also check for overloading vec
6908 * call.c (build_method_call): Also delete second argument for vec
6911 * decl.c (grokdeclarator): Correct complaints again.
6912 (grokdeclarator): Fix segfault on null declarator.
6913 (decls_match): Also accept redeclaration with no arguments if both
6914 declarations were in C context. Bash TREE_TYPE (newdecl) here.
6915 (duplicate_decls): Instead of here.
6917 * parse.y (nested_name_specifier_1): Lose rules for dealing with
6918 syntax errors nicely, since they break parsing of 'const i;'.
6920 * decl.c (lookup_name): if (got_scope == current_class_type)
6921 val = IDENTIFIER_CLASS_VALUE (name).
6923 * search.c (lookup_nested_tag): Look in enclosing classes, too.
6925 * spew.c (yylex): Only look one character ahead when checking for a
6928 * lex.c (check_newline): Read first nonwhite char before
6929 incrementing lineno.
6931 * decl.c (grokdeclarator): Don't claim that typedefs are variables
6934 * parse.y: Divide up uses of unqualified_id into
6935 notype_unqualified_id and unqualified_id, so that TYPENAME can be
6936 used as an identifier after an object.
6938 * class.c (push_nested_class): Don't push into non-class scope.
6940 * decl.c (grokdeclarator): If an identifier could be a type
6941 conversion operator, but has no associated type, it's not a type
6942 conversion operator.
6944 * pt.c (unify): Check for equality of constants better.
6946 * decl.c (grokdeclarator): Don't complain about access decls.
6948 Sun Apr 10 02:39:55 1994 Jason Merrill (jason@deneb.cygnus.com)
6950 * decl.c (grokdeclarator): pedwarn about data definitions without
6953 * parse.y (datadef): Don't pedwarn about decls without types here,
6954 since that is valid for functions.
6955 (fn.def2, component_decl): Support constructors with declmods again.
6956 (nomods_initdecls): For decls without any mods, so that we don't try
6957 to get declspecs from some arbitrary $0.
6959 * search.c (lookup_field): Use cp_error.
6961 * parse.y (nested_name_specifier_1): Don't check aggr/non-aggr type
6962 here; it breaks destructors for non-aggr types.
6964 * decl.c (lookup_name): Only look for TYPE_DECLs in base classes of
6965 a type being defined, like the comment says.
6966 If got_scope is not an aggregate, just return NULL_TREE.
6968 * pt.c (create_nested_upt): Kung's code for creating types nested
6969 within uninstantiated templates now lives here (it used to live in
6970 hack_more_ids). It needs to be expanded.
6972 * parse.y: Stop calling see_typename so much.
6974 * decl.c (lookup_name): Deal with TTPs and UPTs.
6976 * lex.c (real_yylex): Don't set looking_for_typename just because we
6978 (dont_see_typename): #if 0 out.
6980 * spew.c (yylex): Increment looking_for_typename if the next
6981 character is SCOPE, rather than setting it to 1; this way, the value
6982 from seeing an aggr specifier will not be lost. This kinda relies
6983 on looking_for_typename never being < 0, which is now true.
6985 * parse.y (nested_name_specifier_1): Accept TEMPLATE_TYPE_PARMs,
6987 (named_class_head_sans_basetype): Accept template types, too. Oops.
6989 Fri Apr 8 16:39:35 1994 Jason Merrill (jason@deneb.cygnus.com)
6991 * decl2.c (reparse_decl_as_expr1): Handle SCOPE_REFs.
6993 * parse.y: Lose START_DECLARATOR.
6995 * search.c (lookup_nested_tag): New function to scan CLASSTYPE_TAGS
6998 * parse.y: Simplify fn.def2 and component_decl. Support 'enum
6999 A::foo' syntax. Catch invalid scopes better.
7001 * parse.y, lex.c: lose TYPENAME_COLON.
7003 * decl2.c (groktypefield): #if 0 out.
7005 * decl.c (lookup_name): If the type denoted by got_scope is
7006 currently being defined, look in CLASSTYPE_TAGS rather than FIELDS.
7008 * class.c (push_nested_class): Don't try to push into
7011 Fri Apr 8 07:26:36 1994 Brendan Kehoe (brendan@lisa.cygnus.com)
7013 * Makefile.in (stamp-parse): Update count of conflicts to 33.
7015 Thu Apr 7 17:47:53 1994 Jason Merrill (jason@deneb.cygnus.com)
7017 A saner implementation of nested types that treats template types
7018 no differently from non-template types. There are still some
7019 shortcomings of our system; most notably, it is difficult to look
7020 for a nested type that is hidden by another name, because of the way
7021 we keep track of hidden types. But this shouldn't be a problem for
7022 just about anyone. Perhaps lookup_field should be fixed up a bit.
7024 * spew.c: Moved handling of nested types/scoping from the lexer
7025 into the parser. Removed variable template_type_seen_before_scope.
7026 Removed functions frob_identifier, hack_more_ids, and various cruft
7027 that was #if 0'd out in the past, reducing the size of the file from
7028 1146 lines to 450 lines. We can't quite do away with spew.c yet,
7029 though; we still need it for do_aggr () and checking for SCOPE after
7030 the current identifier. And setting lastiddecl.
7032 * parse.y: Moved handling of nested types/scoping from the lexer
7033 into the parser, using a new global variable `got_scope'. Reduced
7034 the number of states by 53. Implemented all uses of explicit global
7035 scope. Removed terminals SCOPED_TYPENAME and SCOPED_NAME. Removed
7036 nonterminals tmpl.1, scoped_base_class, id_scope, typename_scope,
7037 scoped_typename. Added nonterminals nested_type,
7038 qualified_type_name, complete_type_name, qualified_id, ptr_to_mem,
7039 nested_name_specifier, global_scope, overqualified_id, type_name.
7040 Changed many others. Added 9 new reduce/reduce conflicts, which are
7041 nested type parallels of 9 that were already in the grammar for
7042 non-nested types. Eight of the now 33 conflicts should be removed
7043 in the process of resolving the late binding between variable and
7046 * gxxint.texi (Parser): Update.
7048 * cp-tree.h (IS_AGGR_TYPE_CODE): Add UNINSTANTIATED_P_TYPE.
7050 * lex.h: Add decl for got_scope.
7052 * lex.c (see_typename): Claim to be the lexer when calling
7055 * decl.c (lookup_name): When called from the lexer, look at
7056 got_scope and looking_at_typename; otherwise don't.
7058 Thu Apr 7 22:05:47 1994 Mike Stump <mrs@cygnus.com>
7060 31th Cygnus<->FSF merge.
7062 Thu Apr 7 17:47:53 1994 Jason Merrill (jason@deneb.cygnus.com)
7064 * decl2.c (mark_vtable_entries): Call this to mark all the
7065 entries in the vtable addressable.
7066 (finish_decl_parsing): Handle SCOPE_REFs.
7068 * decl.c (decls_match): Always call compparms with strict == 1.
7069 Handle the special case of C function redecl here.
7070 (duplicate_decls): Only keep the old type if the new decl takes no
7073 * typeck.c (compparms): Also allow t1 to be ... if strict == 0.
7075 Thu Apr 7 16:17:50 1994 Mike Stump <mrs@cygnus.com>
7077 * class.c (build_vtable_entry): Fix breakage introduced Apr 5
7080 Wed Apr 6 16:05:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
7082 * init.c (build_virtual_init), search.c (build_vbase_vtables_init),
7083 ch-tree.h: Every place these functions were called, the result was
7084 immediately passed to expand_expr_stmt. Reduce redundancy by
7085 calling expand_expr_init *inside* these functions. These
7086 makes for a simpler interface, and we don't have to build
7087 compound expressions. Hence, rename these function to:
7088 expand_virtual_init and expand_vbase_vtables_init respectively.
7089 * init.c, decl.c: Change callers of these functions.
7090 * init.c, cp-tree.h (expand_virtual_init): Make static.
7092 * decl2.c (finish_file): Check TREE_PUBLIC||TREE_ADDRESSABLE
7093 rather than DECL_SAVED_INSNS before emitting inlines.
7095 Wed Apr 6 13:06:39 1994 Jason Merrill (jason@deneb.cygnus.com)
7097 * spew.c (init_spew): #if 0 out stuff used by arbitrate_lookup.
7099 * decl.c (duplicate_decls): If this is a new declaration of an
7100 extern "C" function, keep the type (for the argtypes).
7101 (redeclaration_error_message): Don't check DECL_LANGUAGE here.
7102 (decls_match): Call compparms with a value of strict dependent on
7103 the value of strict_prototypes for DECL_LANGUAGE (oldecl).
7105 * typeck.c (compparms): ... is only equivalent to non-promoting
7106 parms if we're not being strict.
7108 * parse.y (empty_parms): Don't check flag_ansi || pedantic here.
7110 * decl.c (init_decl_processing): if (flag_ansi || pedantic)
7111 strict_prototypes_lang_c = strict_prototypes_lang_cplusplus;
7113 * decl2.c (grok_function_init): Don't set DECL_INITIAL on pure

7119 * tree.def (THUNK_DECL): New TREE_CODE.
7120 * cp-tree.h (FNADDR_FROM_VTABLE_ENTRY), tree.c
7121 (fnaddr_from_vtable_entry): Handle flag_vtable_thunks case.
7122 * cp-tree.h (memptr_type): New variable.
7123 * class.c (build_vtable_entry): Build thunk if necessary.
7124 * class.c (build_vfn_ref): If using thunks, don't need
7125 to add delta field from vtable (there is none!).
7126 * decl.c: Add memptr_type as well as vtable_entry_type.
7127 If using thunks, the latter is just ptr_type_node.
7128 * gc.c, typeck.c: Use memptr_typeChange, not vtable_entry_type.
7129 * decl2.c (finish_vtable_vardecl): Handle thunks.
7130 * expr.c (cplus_expand_expr): Support THUNK_DECL.
7132 * decl.c (grokdeclarator): Set DECL_THIS_EXTERN if "extern".
7133 * decl.c (start_function): Set current_extern_inline based on
7134 DECL_THIS_EXTERN, not TREE_PUBLIC.
7135 * decl.c (finish_function): Call mark_inline_for_output if needed,
7137 Improve intelligence about when to emit inlines.
7138 * cp-tree.h (lang_decl_flags): New field saved_inline.
7139 * cp-tree.h (DECL_SAVED_INLINE): New macro.
7140 * class.c (add_virtual_function): Don't set TREE_ADDRESSABLE.
7141 * decl.h, decl.c (pending_addressable_inlines): Removed.
7142 * decl2.c (pending_addressable_inlines): Renamed to saved_inlines.
7143 * decl2.c (mark_inline_for_output): Do nothing if
7144 DECL_SAVED_INLINE; otherwise set it (and add to saved_inlines list).
7145 * decl2.c (finish_vtable_vardecl): SET_CLASSTYPE_INTERFACE_KNOWN
7146 and set CLASSTYPE_INTERFACE_ONLY if there is a non-inline virtual.
7147 * decl2.c (finish_file): Writing out inlines later, so we can
7148 also handle the ones needed for vtbales.
7149 * decl2.c (write_vtable_entries, finish_vtable_typedecl): Removed.
7151 * cp-tree.h, class.c, decl2.c, search.c: Remove -fvtable-hack
7152 and flag_vtable_hack. Use -fvtable-thunks and flag_vtable_thunks
7153 instead. (The rationale is that these optimizations both break binary
7154 compatibility, but should become the default in a future release.)
7156 Wed Apr 6 10:53:56 1994 Mike Stump <mrs@cygnus.com>
7158 * class.c (modify_vtable_entries): Never reset the DECL_CONTEXT
7159 of a fndecl, as we might not be from that vfield.
7161 Tue Apr 5 17:43:35 1994 Kung Hsu (kung@mexican.cygnus.com)
7163 * class.c (add_virtual_function): fix bug for pure virtual, so
7164 that DECL_VINDEX of the dummy decl copied won't be error.
7165 (see also Apr 4 change)
7167 Tue Apr 5 17:23:45 1994 Per Bothner (bothner@kalessin.cygnus.com)
7169 * typeck.c (c_expand_return): Before checking that we're not
7170 returning the address of a local, make sure it's a VAR_DECL.
7171 (And don't worry about it being a TREE_LIST.)
7173 Tue Apr 5 13:26:42 1994 Jason Merrill (jason@deneb.cygnus.com)
7175 * parse.y (YYDEBUG): Always define.
7176 * lex.c (YYDEBUG): Ditto.
7178 Mon Apr 4 11:28:17 1994 Kung Hsu (kung@mexican.cygnus.com)
7180 * class.c (finish_struct): backup out the change below, put the
7181 new change for the same purpose. The change below breaks code.
7183 * class.c (finish_struct): if pure virtual, copy node and make
7184 RTL point to abort, then put in virtual table.
7185 * decl2.c (grok_function_iit): reinstate Mar 31 change.
7187 Sat Apr 2 03:12:58 1994 Jason Merrill (jason@deneb.cygnus.com)
7189 * init.c (build_new): pedwarn about newing const and volatile
7192 * tree.c (get_identifier_list): Only do the special handling
7193 thing if we're dealing with the main variant of the record type.
7195 * cvt.c (convert_to_reference): When converting between
7196 compatible reference types, use the pointer conversion machinery.
7197 Don't just blindly overwrite the old type.
7199 Fri Apr 1 17:14:42 1994 Jason Merrill (jason@deneb.cygnus.com)
7201 * call.c (build_method_call): When looking at global functions,
7202 be sure to use instance_ptr for the first argument, not some version
7203 of it that has been cast to a base class. Also do this before
7204 comparing candidates.
7206 Thu Mar 31 19:50:35 1994 Jason Merrill (jason@deneb.cygnus.com)
7208 * call.c (build_method_call): Constructors can be called for
7211 Thu Mar 31 16:20:16 1994 Kung Hsu (kung@mexican.cygnus.com)
7213 * decl2.c (grok_func_init): do not abort as rtl for pur virtual
7214 fucntions. They can be defined somewhere else.

7218 * decl.c (init_decl_processing): Declare __builtin_return_address

7223 * typeck2.c (store_init_value): Integral constant variables are
7224 always constant, even when doing -fpic.

7228 * decl.c (redeclaration_error_message): Pass the types to
7231 Wed Mar 30 21:29:25 1994 Mike Stump <mrs@cygnus.com>
7233 Cures incorrect errors about pure virtuals in a class, when they
7234 have been overridden in a derived class.
7236 * search.c (get_abstract_virtuals): Reimplement.
7237 * search.c (get_abstract_virtuals_1): New routine.
7239 Wed Mar 30 14:10:04 1994 Jason Merrill (jason@deneb.cygnus.com)
7241 * pt.c (push_template_decls): Make the pushed level pseudo
7244 * parse.y (extdefs): Don't pop everything if the current binding
7245 level is pseudo_global.
7247 * decl.c (pop_everything): Stop on reaching a pseudo-global
7250 * cp-tree.h (DECL_FUNCTION_MEMBER_P): Change to more reliable test.

7253 the old decl actually had an initializer.
7255 * {various}: Clean up gcc -W complaints.
7257 * cp-tree.h (DECL_FUNCTION_MEMBER_P): Currently defined to be
7258 (DECL_CONTEXT (NODE) != NULL_TREE).
7260 * parse.y (lang_extdef): Call pop_everything if necessary.
7262 * decl.c (pop_everything): New function for popping binding
7263 levels left over after a syntax error.

7265 a function is a member.
7267 Wed Mar 30 14:20:50 1994 Mike Stump <mrs@cygnus.com>
7269 Cures calling a more base base class function, when a more derived
7270 base class member should be called in some MI situations.
7272 * search.c (make_binfo): Use more the more specialized base
7273 binfos from the binfo given as the second argument to make_binfo,
7274 instead of the unspecialized ones from the TYPE_BINFO.
7275 * class.c (finish_base_struct): Ditto, update callers.
7276 * search.c (dfs_get_vbase_types): Ditto.
7277 * tree.c (propagate_binfo_offsets, layout_vbasetypes): Ditto.

7281 Wed Mar 30 14:10:04 1994 Jason Merrill (jason@deneb.cygnus.com)
7283 * decl.c (pushdecl): If pushing a C-linkage function, only do a
7284 push_overloaded_decl.

7300 (redeclaration_error_message): Deal with linkage.
7302 * decl.c (start_function): If push_overloaded_decl returns an
7303 older version of the function, deal with it.
7305 * decl.c (start_function): Be sure only to push_overloaded_decl
7308 * decl.c (grokfndecl): Put back clearing of DECL_CHAIN for
7310 (start_function): Lose broken and redundant code for checking old
7313 * init.c (add_friend): Give line numbers of both friend decls
7314 when warning about re-friending.
7316 * pt.c (tsubst): Use comptypes rather than == to compare the
7317 types of the method as declared and as defined, since default
7318 parameters may be different.
7320 * call.c (build_method_call): Use brendan's candidate printing
7323 * decl.c (start_method): Methods defined in the class body are
7324 inline whether or not it's a template class.
7326 Mon Mar 28 16:39:26 1994 Jason Merrill (jason@deneb.cygnus.com)

7339 Lose old code for checking arg types of functions.
7340 Check for overloaded C functions.
7341 (pushdecl): Deal with overloaded functions.
7342 (start_decl): Expect pushdecl to return an appropriate function decl.
7343 (start_function): Ditto.
7344 (push_overloaded_decl): Don't check for overloaded C functions.
7346 * *.c: Stop using DECL_OVERLOADED, it being archaic.
7347 TREE_OVERLOADED should probably go, too.
7349 Mon Mar 28 14:00:45 1994 Ron Guilmette (rfg@netcom.com)
7351 * typeck.c (comp_target_types): Call comp_target_parms with
7354 Sun Mar 27 00:07:45 1994 Jason Merrill (jason@deneb.cygnus.com)

7401 Thu Mar 24 02:10:46 1994 Jason Merrill (jason@deneb.cygnus.com)
7403 * cvt.c (convert_to_reference): If i is an lvalue,
7404 (int &)i -> *(int*)&i, as per 5.2.8p9 of the latest WP.
7405 (convert_force): Call convert_to_reference with LOOKUP_COMPLAIN.
7407 Wed Mar 23 17:45:37 1994 Jason Merrill (jason@deneb.cygnus.com)

7458 passed a UNION_TYPE.
7460 Tue Mar 22 12:44:54 1994 Jason Merrill (jason@deneb.cygnus.com)
7462 These patches implement handling of redefinition/redeclaration of
7465 * typeck.c (comptypes): Simplify. All TEMPLATE_TYPE_PARMs are
7466 considered compatible.
7468 * parse.y (template_def): Pass defn argument to end_template_decl.
7470 * pt.c (end_template_decl): Add defn argument. Check for
7471 redefinition. Simplify.
7473 * error.c (OB_UNPUT): New macro, to remove mistakes.
7474 (aggr_variety): Subroutine of dump_aggr_type.
7476 * decl.c (decls_match): Support templates.

7481 * cp-tree.h (DECL_TEMPLATE_MEMBERS): Use DECL_SIZE instead of
7484 Mon Mar 21 11:46:55 1994 Jason Merrill (jason@deneb.cygnus.com)
7486 * error.c (dump_decl): Support class template decls.
7487 (dump_type): Don't adorn template type parms.
7489 * decl.c (duplicate_decls): Save DECL_TEMPLATE_INFO from old decl
7490 if it was a definition.
7491 (redeclaration_error_message): Do the cp_error thang, and reject
7492 redefinition of templates.
7494 Mon Mar 21 19:36:06 1994 Per Bothner (bothner@kalessin.cygnus.com)
7496 * decl.c (grokdeclarator): Set TREE_PUBLIC for METHOD_TYPE
7497 in FIELD context, when appropriate. Also,
7498 CLASSTYPE_INTERFACE_ONLY is irrelevant to setting TREE_PUBLIC.
7499 Also, simplify check for bogus return specifiers.
7501 Mon Mar 21 11:46:55 1994 Jason Merrill (jason@deneb.cygnus.com)
7503 * parse.y (after_type_declarator1): Expand type_quals.
7504 (notype_declarator1): Ditto.
7507 Sat Mar 19 01:05:17 1994 Jason Merrill (jason@deneb.cygnus.com)
7509 * decl.c (grokdeclarator): Treat class-local typedefs like static
7510 members; i.e. 'typedef int f();' means that f is a function type,
7513 * parse.y (decl): Change direct_* back to *.
7514 (type_id): Change direct_abstract_declarator to absdcl.
7515 (direct_declarator, direct_initdecls, direct_initdcl0): Remove again.

7522 * class.c (current_lang_stacksize): No longer static.
7524 * decl.c (struct saved_scope): Add lang_base, lang_stack,
7525 lang_name, lang_stacksize, and named_labels.
7526 (push_to_top_level): Save them.
7527 (pop_from_top_level): Restore them.
7529 * gxxint.texi (Parser): Update.
7531 These two patches finish moving the task of expr/declarator
7532 ambiguity resolution from the lexer to the parser, and add one more
7533 r/r conflict. START_DECLARATOR can now be nuked.
7535 * parse.y (decl): Add "direct_" in typespec X rules.
7536 (direct_declarator): New nonterminal for
7537 direct_after_type_declarator and direct_notype_declarator.

7540 (named_parm): Add typespec direct_declarator rule.
7542 * spew.c (yylex): #if 0 out START_DECLARATOR insertion.
7544 These two patches disable some excessive cleverness on the part of
7545 g++; a non-class declaration always hides a class declaration in the
7546 same scope, and g++ was trying to unhide it depending on the
7547 enclosing expression.
7549 * spew.c (arbitrate_lookup): #if 0 out.
7551 * decl.c (lookup_name): Never call arbitrate_lookup.
7553 * parse.y (complex_notype_declarator1): Add '*'
7554 complex_notype_declarator1 and '&' complex_notype_declarator1 rules.
7556 * parse.y (complex_direct_notype_declarator): Restore id_scope
7557 see_typename TYPENAME rule, remove all other rules beginning with
7559 (notype_unqualified_id): Add '~' see_typename IDENTIFIER rule.
7561 Thu Mar 17 17:30:01 1994 Jason Merrill (jason@deneb.cygnus.com)
7563 These changes fix the compiler's handling of the functional cast/
7564 object declaration ambiguities in section 6.8 of the ARM. They also
7565 add 11 reduce/reduce conflicts. Sigh.
7567 * parse.y: Add precedence decls for OPERATOR and '~'.
7568 (notype_unqualified_id): New nonterminal, encompasses all of the
7569 ANSI unqualified-id nonterminal except TYPENAMEs.
7570 (expr_or_declarator): New nonterminal to delay parsing of code like
7572 (primary): Use notype_unqualified_id.

7577 an expr_or_declarator.
7578 (complex_direct_notype_declarator): A direct_notype_declarator that
7579 doesn't conflict with expr_or_declarator. Use
7580 notype_unqualified_id. Remove id_scope see_typename TYPENAME rule.
7581 (functional_cast): New nonterminal, for the three functional cast
7582 rules. So that they can be moved after
7583 complex_direct_notype_declarator.
7584 (see_typename): Don't accept type_quals any more.
7586 * decl2.c (reparse_decl_as_expr): New function to deal with parse
7587 nodes for code like `int (*a)++;'.
7588 (reparse_decl_as_expr1): Recursive subroutine of the above.
7589 (finish_decl_parsing): New function to deal with parse nodes for
7590 code like `int (*a);'. See the difference?
7592 Thu Mar 17 12:16:10 1994 Mike Stump <mrs@cygnus.com>
7594 These changes break binary compatibility in code with classes
7595 that use virtual bases.
7597 * search.c (dfs_get_vbase_types): Simplify and correct to make
7598 sure virtual bases are initialized in dfs ordering.
7599 * search.c (get_vbase_types): Simplify and make readable.
7601 Thu Mar 17 12:01:10 1994 Jason Merrill (jason@deneb.cygnus.com)

7607 * parse.y (typespec): add SCOPE TYPENAME for global scoped
7610 * decl.c (complete_array_type): fix a bug that in -pendantic
7611 mode even there's no initializer, it will continue to build
7614 Wed Mar 16 17:43:07 1994 Jason Merrill (jason@deneb.cygnus.com)
7616 * parse.y (direct_notype_declarator): Add PTYPENAME rule, remove
7617 all of the scoped PTYPENAME rules.
7619 Wed Mar 16 16:39:02 1994 Mike Stump <mrs@cygnus.com>
7621 * init.c (build_offset_ref): The value of A::typedef_name is
7622 always the TYPE_DECL, and never an error.
7624 Tue Mar 15 20:02:35 1994 Jason Merrill (jason@deneb.cygnus.com)
7626 * search.c (get_base_distance_recursive): Two binfos can only
7627 represent the same object if they are both via_virtual.
7629 * class.c (finish_base_struct): Check vbases for ambiguity, too.
7631 * search.c (get_vbase_types): Accept binfo argument, too.
7633 Tue Mar 15 19:22:05 1994 Kung Hsu (kung@mexican.cygnus.com)
7635 * decl.c (complete_array_type): complete TYPE_DOMAIN of the
7636 initializer also, because back-end requires it.
7638 Tue Mar 15 15:33:31 1994 Jason Merrill (jason@deneb.cygnus.com)
7640 * error.c (dump_expr): Support member functions (which show up as
7643 Mon Mar 14 16:24:36 1994 Mike Stump <mrs@cygnus.com>
7645 * init.c (build_new): Set the return type of multidimensional

7665 * parse.y (regcast_or_absdcl): New nonterminal to implement late
7666 reduction of constructs like `int ((int)(int)(int))'.

7671 (direct_abstract_declarator): Replace '(' parmlist ')' rule with
7672 '(' complex_parmlist ')' and regcast_or_absdcl.
7674 (complex_parmlist): Parmlists that are not also typenames.
7675 (parms_comma): Enabler.
7676 (named_parm): A parm that is not also a typename. Use declarator
7677 rather than dont_see_typename abs_or_notype_decl. Expand
7678 typed_declspecs inline.
7679 (abs_or_notype_decl): Lose.
7680 (dont_see_typename): Comment out.
7681 (bad_parm): Break out abs_or_notype_decl into two rules.

7685 * decl2.c (reparse_decl_as_casts): New function to change parse
7686 nodes for `(int)(int)(int)' from "function taking int and returning
7687 function taking int and returning function taking int" to "... cast
7688 to int, cast to int, cast to int".
7690 * decl2.c (reparse_decl_as_expr): Recursive function to change
7691 parse nodes for `A()()' from "function returning function returning
7692 A" to "A().operator()".
7694 * parse.y (primary): Replace `typespec LEFT_RIGHT' rule with
7695 `typespec fcast_or_absdcl' rule.
7696 (fcast_or_absdcl): New nonterminal to implement late reduction of

7705 * tree.c (lvalue_p): Improve OFFSET_REF handling, so that it
7706 matches Section 5.5.
7708 Fri Mar 4 14:01:59 1994 Jason Merrill (jason@deneb.cygnus.com)
7710 * error.c (dump_type_prefix): Don't print basetype twice for

7715 * typeck.c (convert_arguments): Handle setHandler(A::handlerFn)
7716 so that it is like setHandler(&A::handlerFn). Cures an `invalid

7721 * gxxint.texi (Copying Objects): New section discussing default
7722 op= problems with virtual inheritance.
7724 * decl2.c (grokoptypename): Just does grokdeclarator and
7725 build_typename_overload, since the parser can't call grokdeclarator
7728 * method.c (build_typename_overload): Set IDENTIFIER_GLOBAL_VALUE
7729 and TREE_TYPE on generated identifiers.
7731 * decl.c (grokdeclarator): Don't deal with TYPE_EXPRs anymore.
7733 * parse.y (parm): Convert `const char *' to `__opPCc' here.

7745 * call.c (build_method_call): Handle b->setHandler(A::handlerFn)
7746 so that it is like b->setHandler(&A::handlerFn). Cures an `invalid

7758 rather than waiting until later.
7760 Wed Mar 2 14:12:23 1994 Jason Merrill (jason@deneb.cygnus.com)
7762 * parse.y (unary_expr): Use 'typename' in 'new' rules, rather

7765 (abs_or_notype_decl): Ditto.
7766 (absdcl): Lose empty rule.
7767 (conversion_declarator): New nonterminal for 'typename' of 'operator
7769 (operator_name): Use it instead of absdcl.

7774 directly. Add rules with reserved_typespecquals.
7775 (reserved_declspecs): Don't accept typespecqual_reserved at the
7776 beginning of the list. The typed_declspecs rule will deal with this
7778 (declmods): Accept nonempty_type_quals, rather than TYPE_QUAL
7781 * parse.y (direct_notype_declarator,
7782 direct_after_type_declarator, direct_abstract_declarator): Split up
7783 the declarator1 nonterminals to match the draft standard and avoid
7785 (new_type_id, new_declarator, direct_new_declarator,

7799 (get_decl_list): Use it.
7800 (list_hash_lookup_or_cons): Ditto.
7802 * parse.y (typed_declspecs, declmods): It's not necessary to hash
7803 the declspecs on class_obstack, so don't. This way typed_typespecs
7804 can reduce to typed_declspecs.
7806 Wed Mar 2 14:29:18 1994 Jason Merrill (jason@cygnus.com)
7808 * cvt.c (build_up_reference): If we aren't checking visibility,
7809 also allow base->derived conversions.
7811 Mon Feb 28 15:14:29 1994 Per Bothner (bothner@kalessin.cygnus.com)
7813 * typeck.c (build_c_cast): Remove bogus hack when converting
7814 to a reference type.
7816 * cp-tree.h (lang_decl::vbase_init_list, DECL_VBASE_INIT_LIST):
7818 (lang_stype::methods, lang_decl::next_method): New fields.
7819 (CLASSTYPE_METHODS, DECL_NEXT_METHOD): New macros.
7820 * decl.c (duplicate_decls): Preserve DECL_NEXT_METHOD.
7822 * cp-tree.h, decl2.c (flag_vtable_hack): New flag.
7823 * decl2.c (finish_vtable_vardecl): If flag_vtable_hack,
7824 and !CLASSTYPE_INTERFACE_KNOWN, try to use the presence of
7825 a non-inline virtual function to control emitting of vtables.
7826 * class.c (finish_struct): Build CLASSTYPE_METHODS list.
7827 * search.c (build_vbase_vtables_init): Don't assemble_external
7828 (yet) if flag_vtable_hack.

7833 * parse.y (component_decl): Don't include "typed_declspecs
7834 declarator ';'" speedup, since it breaks enums.
7836 Fri Feb 25 15:43:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
7838 * class.c (finish_struct): Minor optimization for building

7845 Thu Feb 24 22:26:19 1994 Mike Stump <mrs@cygnus.com>
7847 * lex.c (check_newline): #pragma interface can take a string
7848 argument, just like #pragma implementation. #pragma implementation
7849 checks for garbage on the line, line #pragma interface does. Main
7850 input files do not auto implement like named files, #pragma
7851 implementation must be used explicitly.
7853 Thu Feb 24 17:09:01 1994 Jason Merrill (jason@deneb.cygnus.com)
7855 * parse.y (components): Handle list of one again.

7857 (after_type_declarator1): Take maybe_raises out again.
7859 * gxxint.texi (Parser): Document additional r/r conflict.

7865 * Makefile.in (stamp-parse): Update expected conflict count.
7867 * parse.y (various): Replace "declmods declarator" with "declmods
7868 notype_declarator". The comment saying that "declmods declarator ';'"
7869 corresponds to "int i;" was wrong; it corresponds to "const i;".
7870 (component_decl): Add "typed_declspecs declarator ';'" rule; this
7871 *does* correspond to "int i;". Change "declmods components" to
7872 "declmods notype_components".

8911 (lang_decode_option): Set warn_return_type, not explicit_*, for

8915 * cp-decl.c (grokdeclarator): Use warn_return_type, not explicit_*.

9304 (build_method_call): When we had some candidates, but didn't get a
9305 usable match, don't report that we got an error with the first

9307 candidates with print_candidates. In the second pass, make sure we
9308 clear out ever_seen, so we can accurately count the number of

9426 (decl_value_member): Like value_member, but for DECL_CHAINs.
9428 * cp-decl.c (duplicate_decls): Deal with new overloading.
9429 (start_decl): Ditto.
9431 * cp-class.c (instantiate_type): Deal with new overloading.
9433 * cp-call.c (convert_harshness_ansi): Deal with new overloading.

9439 * cp-tree.c (get_unique_fn): New function; returns FUNCTION_DECL
9440 if unambiguous, NULL_TREE otherwise.
9441 (get_first_fn): Returns the first appropriate FUNCTION_DECL.
9442 (is_overloaded_fn): Returns whether or not the passed tree is
9443 a function or list of functions.
9445 * cp-init.c (init_init_processing): use `get_first_fn' to find
9446 the FUNCTION_DEFN for new and delete.
9448 * cp-decl.c (push_overloaded_decl): Use new overloading strategy, cut
9449 code size in half (I spit on special cases).
