1739 * parse.y (do_xref): Lose.
1740 (named_class_head): If we see 'class foo:' we know it's a
1741 definition, so don't worry about base lists for non-definitions.

1803 initializers are done as tdecls are initialized in the global
1804 initializer. Also Pick up any new tdecls or vtables needed by
1805 synthesized methods.
1807 * class.c (finish_struct): Simplify. We have to do rtti scanning at
1808 end, so we might as well do all of it there.

1812 * call.c (build_method_call): Fix -fthis-is-variable for 32-bit

1821 in finish_prevtable_vardecl.
1822 * decl2.c (finish_file): Call finish_prevtable_vardecl.
1823 * gc.c (build_generic_desc): Allow it to be called when not at the

1825 (build_t_desc): Rearrange a bit so that it really works and is
1827 * class.c (finish_struct): Don't decide on tdecls here, as we have
1828 to wait until the end of the file in general to decide whether or
1831 Mon Jan 30 01:00:40 1995 Jason Merrill <jason@phydeaux.cygnus.com>

1860 Sat Jan 28 09:10:44 1995 Mike Stump <mrs@cygnus.com>
1862 * decl2.c (finish_vtable_vardecl): Now set the
1863 interface/implementation of vtables on the first virtual function,
1864 if one exists, otherwise we use the old method. This is a major win
1865 in terms of cutting down the size of objects and executables in
1866 terms of text space and data space. Now most of the savings that
1867 #pragma interface/implementation gives is automatic in a fair number

1886 * parse.y: Add END_OF_LINE token.
1888 * lex.c (check_newline): Set linemode when we see a # directive, and
1889 unset it when we're done. Turn all 'return's into 'goto skipline'.
1890 Fix all uses of '\n', since we won't see it anymore. Put back the
1891 character we read before checking for a sysv or target pragma.
1892 (real_yylex): If we see an EOF in linemode, return END_OF_LINE.
1893 (handle_sysv_pragma): Don't look at the input stream; quit when we

1929 * typeck.c (convert_for_assignment): Initialize variable before use.

2053 they have the same precision.
2055 * decl.c (grokparms): Call convert_for_initialization to check
2058 * init.c (build_new): void_type_node has a size (of 0).

4410 constructor of a signature pointer/reference from a signature

5443 use "VT" rather than "vt" due to binary incompatibility.

5527 expand_indirect_vtbls_init. General cleanup. Use

5535 Tue Apr 19 12:51:59 1994 Jason Merrill (jason@deneb.cygnus.com)
5537 * cvt.c (convert_to_reference): Use NOP_EXPRs to switch between
5538 reference and pointer types instead of bashing the types directly.

5541 whether the function is overloaded or not, rather than
5543 * *: Remove all uses of TREE_OVERLOADED.

5679 Clean up overloading of the template name.
5680 * class.c (pushclass): overload the template name whenever pushing

5709 (build_opfncall): Ditto.
5710 * lex.c (init_lex): Set up values of ansi_opname and opname_tab for
5711 vec new/delete. vec new uses "__vn", and vec delete uses "__vd".
5712 * init.c (init_init_processing): Set up BIVN and BIVD.
5713 (do_friend): Don't clean up after mistaken setting of TREE_GETS_NEW,
5714 since it doesn't happen any more.
5715 (build_new): Support vec new. Always call something.
5716 (build_x_delete): Support vec delete.
5717 (build_vec_delete): Lose dtor_dummy argument, add use_global_delete,
5718 and pass it to build_x_delete.
5719 * decl2.c (delete_sanity): Don't change behavior by whether or not
5720 the type has a destructor. Pass use_global_delete to
5722 (coerce_delete_type): Make sure that the type returned has a first
5723 argument of ptr_type_node.
5724 * decl.c (init_decl_processing): Also declare the global vec
5726 (grokdeclarator): Also force vec new/delete to be static.
5727 (grok_op_properties): Note presence of vec new/delete, and play with
5728 their args. If vec delete takes the optional size_t argument, set
5729 TYPE_VEC_DELETE_TAKES_SIZE.
5730 * cp-tree.h (TYPE_GETS_{REG,VEC}_DELETE): New macros to simplify
5731 checking for one delete or the other.
5732 (lang_type): gets_new and gets_delete are now two bits long. The
5733 low bit is for the non-array version. Lose gets_placed_new.
5734 (TYPE_VEC_DELETE_TAKES_SIZE): New macro indicating that the vec
5735 delete defined by this class wants to know how much space it is
5737 (TYPE_VEC_NEW_USES_COOKIE): New macro to indicate when vec new must
5738 add a header containing the number of elements in the vector; i.e.
5739 when the elements need to be destroyed or vec delete wants to know
5741 * class.c (finish_struct_methods): Also check for overloading vec
5743 * call.c (build_method_call): Also delete second argument for vec
5746 * decl.c (grokdeclarator): Correct complaints again.
5747 (grokdeclarator): Fix segfault on null declarator.
5748 (decls_match): Also accept redeclaration with no arguments if both
5749 declarations were in C context. Bash TREE_TYPE (newdecl) here.
5750 (duplicate_decls): Instead of here.
5752 * parse.y (nested_name_specifier_1): Lose rules for dealing with
5753 syntax errors nicely, since they break parsing of 'const i;'.
5755 * decl.c (lookup_name): if (got_scope == current_class_type)
5756 val = IDENTIFIER_CLASS_VALUE (name).
5758 * search.c (lookup_nested_tag): Look in enclosing classes, too.
5760 * spew.c (yylex): Only look one character ahead when checking for a
5763 * lex.c (check_newline): Read first nonwhite char before
5764 incrementing lineno.
5766 * decl.c (grokdeclarator): Don't claim that typedefs are variables
5769 * parse.y: Divide up uses of unqualified_id into
5770 notype_unqualified_id and unqualified_id, so that TYPENAME can be
5771 used as an identifier after an object.
5773 * class.c (push_nested_class): Don't push into non-class scope.
5775 * decl.c (grokdeclarator): If an identifier could be a type
5776 conversion operator, but has no associated type, it's not a type
5777 conversion operator.
5779 * pt.c (unify): Check for equality of constants better.
5781 * decl.c (grokdeclarator): Don't complain about access decls.
5783 Sun Apr 10 02:39:55 1994 Jason Merrill (jason@deneb.cygnus.com)
5785 * decl.c (grokdeclarator): pedwarn about data definitions without
5788 * parse.y (datadef): Don't pedwarn about decls without types here,
5789 since that is valid for functions.
5790 (fn.def2, component_decl): Support constructors with declmods again.
5791 (nomods_initdecls): For decls without any mods, so that we don't try
5792 to get declspecs from some arbitrary $0.
5794 * search.c (lookup_field): Use cp_error.
5796 * parse.y (nested_name_specifier_1): Don't check aggr/non-aggr type
5797 here; it breaks destructors for non-aggr types.
5799 * decl.c (lookup_name): Only look for TYPE_DECLs in base classes of
5800 a type being defined, like the comment says.
5801 If got_scope is not an aggregate, just return NULL_TREE.
5803 * pt.c (create_nested_upt): Kung's code for creating types nested
5804 within uninstantiated templates now lives here (it used to live in
5805 hack_more_ids). It needs to be expanded.
5807 * parse.y: Stop calling see_typename so much.
5809 * decl.c (lookup_name): Deal with TTPs and UPTs.
5811 * lex.c (real_yylex): Don't set looking_for_typename just because we
5813 (dont_see_typename): #if 0 out.
5815 * spew.c (yylex): Increment looking_for_typename if the next
5816 character is SCOPE, rather than setting it to 1; this way, the value
5817 from seeing an aggr specifier will not be lost. This kinda relies
5818 on looking_for_typename never being < 0, which is now true.
5820 * parse.y (nested_name_specifier_1): Accept TEMPLATE_TYPE_PARMs,
5822 (named_class_head_sans_basetype): Accept template types, too. Oops.
5824 Fri Apr 8 16:39:35 1994 Jason Merrill (jason@deneb.cygnus.com)
5826 * decl2.c (reparse_decl_as_expr1): Handle SCOPE_REFs.
5828 * parse.y: Lose START_DECLARATOR.
5830 * search.c (lookup_nested_tag): New function to scan CLASSTYPE_TAGS
5833 * parse.y: Simplify fn.def2 and component_decl. Support 'enum
5834 A::foo' syntax. Catch invalid scopes better.
5836 * parse.y, lex.c: lose TYPENAME_COLON.
5838 * decl2.c (groktypefield): #if 0 out.
5840 * decl.c (lookup_name): If the type denoted by got_scope is
5841 currently being defined, look in CLASSTYPE_TAGS rather than FIELDS.
5843 * class.c (push_nested_class): Don't try to push into
5846 Fri Apr 8 07:26:36 1994 Brendan Kehoe (brendan@lisa.cygnus.com)
5848 * Makefile.in (stamp-parse): Update count of conflicts to 33.
5850 Thu Apr 7 17:47:53 1994 Jason Merrill (jason@deneb.cygnus.com)
5852 A saner implementation of nested types that treats template types
5853 no differently from non-template types. There are still some
5854 shortcomings of our system; most notably, it is difficult to look
5855 for a nested type that is hidden by another name, because of the way
5856 we keep track of hidden types. But this shouldn't be a problem for
5857 just about anyone. Perhaps lookup_field should be fixed up a bit.
5859 * spew.c: Moved handling of nested types/scoping from the lexer
5860 into the parser. Removed variable template_type_seen_before_scope.
5861 Removed functions frob_identifier, hack_more_ids, and various cruft
5862 that was #if 0'd out in the past, reducing the size of the file from
5863 1146 lines to 450 lines. We can't quite do away with spew.c yet,
5864 though; we still need it for do_aggr () and checking for SCOPE after
5865 the current identifier. And setting lastiddecl.
5867 * parse.y: Moved handling of nested types/scoping from the lexer
5868 into the parser, using a new global variable `got_scope'. Reduced
5869 the number of states by 53. Implemented all uses of explicit global
5870 scope. Removed terminals SCOPED_TYPENAME and SCOPED_NAME. Removed
5871 nonterminals tmpl.1, scoped_base_class, id_scope, typename_scope,
5872 scoped_typename. Added nonterminals nested_type,
5873 qualified_type_name, complete_type_name, qualified_id, ptr_to_mem,
5874 nested_name_specifier, global_scope, overqualified_id, type_name.
5875 Changed many others. Added 9 new reduce/reduce conflicts, which are
5876 nested type parallels of 9 that were already in the grammar for
5877 non-nested types. Eight of the now 33 conflicts should be removed
5878 in the process of resolving the late binding between variable and
5881 * gxxint.texi (Parser): Update.
5883 * cp-tree.h (IS_AGGR_TYPE_CODE): Add UNINSTANTIATED_P_TYPE.
5885 * lex.h: Add decl for got_scope.
5887 * lex.c (see_typename): Claim to be the lexer when calling
5890 * decl.c (lookup_name): When called from the lexer, look at
5891 got_scope and looking_at_typename; otherwise don't.
5893 Thu Apr 7 22:05:47 1994 Mike Stump <mrs@cygnus.com>
5895 31th Cygnus<->FSF merge.
5897 Thu Apr 7 17:47:53 1994 Jason Merrill (jason@deneb.cygnus.com)

5908 * typeck.c (compparms): Also allow t1 to be ... if strict == 0.
5910 Thu Apr 7 16:17:50 1994 Mike Stump <mrs@cygnus.com>
5912 * class.c (build_vtable_entry): Fix breakage introduced Apr 5
5915 Wed Apr 6 16:05:10 1994 Per Bothner (bothner@kalessin.cygnus.com)
5917 * init.c (build_virtual_init), search.c (build_vbase_vtables_init),
5918 ch-tree.h: Every place these functions were called, the result was
5919 immediately passed to expand_expr_stmt. Reduce redundancy by
5920 calling expand_expr_init *inside* these functions. These
5921 makes for a simpler interface, and we don't have to build
5922 compound expressions. Hence, rename these function to:
5923 expand_virtual_init and expand_vbase_vtables_init respectively.
5924 * init.c, decl.c: Change callers of these functions.
5925 * init.c, cp-tree.h (expand_virtual_init): Make static.
5927 * decl2.c (finish_file): Check TREE_PUBLIC||TREE_ADDRESSABLE
5928 rather than DECL_SAVED_INSNS before emitting inlines.

5932 * spew.c (init_spew): #if 0 out stuff used by arbitrate_lookup.

5937 (decls_match): Call compparms with a value of strict dependent on
5938 the value of strict_prototypes for DECL_LANGUAGE (oldecl).
5940 * typeck.c (compparms): ... is only equivalent to non-promoting
5941 parms if we're not being strict.
5943 * parse.y (empty_parms): Don't check flag_ansi || pedantic here.
5945 * decl.c (init_decl_processing): if (flag_ansi || pedantic)

5958 * class.c (build_vtable_entry): Build thunk if necessary.
5959 * class.c (build_vfn_ref): If using thunks, don't need
5960 to add delta field from vtable (there is none!).
5961 * decl.c: Add memptr_type as well as vtable_entry_type.
5962 If using thunks, the latter is just ptr_type_node.
5963 * gc.c, typeck.c: Use memptr_typeChange, not vtable_entry_type.
5964 * decl2.c (finish_vtable_vardecl): Handle thunks.
5965 * expr.c (cplus_expand_expr): Support THUNK_DECL.
5967 * decl.c (grokdeclarator): Set DECL_THIS_EXTERN if "extern".
5968 * decl.c (start_function): Set current_extern_inline based on
5969 DECL_THIS_EXTERN, not TREE_PUBLIC.
5970 * decl.c (finish_function): Call mark_inline_for_output if needed,
5972 Improve intelligence about when to emit inlines.
5973 * cp-tree.h (lang_decl_flags): New field saved_inline.
5974 * cp-tree.h (DECL_SAVED_INLINE): New macro.
5975 * class.c (add_virtual_function): Don't set TREE_ADDRESSABLE.

5978 * decl2.c (mark_inline_for_output): Do nothing if
5979 DECL_SAVED_INLINE; otherwise set it (and add to saved_inlines list).
5980 * decl2.c (finish_vtable_vardecl): SET_CLASSTYPE_INTERFACE_KNOWN
5981 and set CLASSTYPE_INTERFACE_ONLY if there is a non-inline virtual.
5982 * decl2.c (finish_file): Writing out inlines later, so we can
5983 also handle the ones needed for vtbales.
5984 * decl2.c (write_vtable_entries, finish_vtable_typedecl): Removed.
5986 * cp-tree.h, class.c, decl2.c, search.c: Remove -fvtable-hack
5987 and flag_vtable_hack. Use -fvtable-thunks and flag_vtable_thunks
5988 instead. (The rationale is that these optimizations both break binary
5989 compatibility, but should become the default in a future release.)
5991 Wed Apr 6 10:53:56 1994 Mike Stump <mrs@cygnus.com>
5993 * class.c (modify_vtable_entries): Never reset the DECL_CONTEXT
5994 of a fndecl, as we might not be from that vfield.
5996 Tue Apr 5 17:43:35 1994 Kung Hsu (kung@mexican.cygnus.com)
5998 * class.c (add_virtual_function): fix bug for pure virtual, so
5999 that DECL_VINDEX of the dummy decl copied won't be error.
6000 (see also Apr 4 change)
6002 Tue Apr 5 17:23:45 1994 Per Bothner (bothner@kalessin.cygnus.com)
6004 * typeck.c (c_expand_return): Before checking that we're not
6005 returning the address of a local, make sure it's a VAR_DECL.
6006 (And don't worry about it being a TREE_LIST.)
6008 Tue Apr 5 13:26:42 1994 Jason Merrill (jason@deneb.cygnus.com)
6010 * parse.y (YYDEBUG): Always define.
6011 * lex.c (YYDEBUG): Ditto.
6013 Mon Apr 4 11:28:17 1994 Kung Hsu (kung@mexican.cygnus.com)
6015 * class.c (finish_struct): backup out the change below, put the
6016 new change for the same purpose. The change below breaks code.
6018 * class.c (finish_struct): if pure virtual, copy node and make
6019 RTL point to abort, then put in virtual table.
6020 * decl2.c (grok_function_iit): reinstate Mar 31 change.

6024 * init.c (build_new): pedwarn about newing const and volatile
6027 * tree.c (get_identifier_list): Only do the special handling
6028 thing if we're dealing with the main variant of the record type.
6030 * cvt.c (convert_to_reference): When converting between
6031 compatible reference types, use the pointer conversion machinery.

6036 * call.c (build_method_call): When looking at global functions,
6037 be sure to use instance_ptr for the first argument, not some version
6038 of it that has been cast to a base class. Also do this before
6039 comparing candidates.

6043 * call.c (build_method_call): Constructors can be called for

6119 push_overloaded_decl.

6149 when warning about re-friending.

6153 parameters may be different.
6155 * call.c (build_method_call): Use brendan's candidate printing
6158 * decl.c (start_method): Methods defined in the class body are
6159 inline whether or not it's a template class.

6178 (start_function): Ditto.
6179 (push_overloaded_decl): Don't check for overloaded C functions.
6181 * *.c: Stop using DECL_OVERLOADED, it being archaic.

6354 These two patches fix crashes on instantiating a template inside a
6355 function with C linkage or containing labels.
6357 * class.c (current_lang_stacksize): No longer static.
6359 * decl.c (struct saved_scope): Add lang_base, lang_stack,
6360 lang_name, lang_stacksize, and named_labels.
6361 (push_to_top_level): Save them.
6362 (pop_from_top_level): Restore them.
6364 * gxxint.texi (Parser): Update.
6366 These two patches finish moving the task of expr/declarator
6367 ambiguity resolution from the lexer to the parser, and add one more
6368 r/r conflict. START_DECLARATOR can now be nuked.
6370 * parse.y (decl): Add "direct_" in typespec X rules.
6371 (direct_declarator): New nonterminal for
6372 direct_after_type_declarator and direct_notype_declarator.
6373 (direct_initdecls): Like initdecls, but uses direct_initdcl0.
6374 (direct_initdcl0): Like initdcl0, but uses direct_declarator.
6375 (named_parm): Add typespec direct_declarator rule.
6377 * spew.c (yylex): #if 0 out START_DECLARATOR insertion.
6379 These two patches disable some excessive cleverness on the part of
6380 g++; a non-class declaration always hides a class declaration in the
6381 same scope, and g++ was trying to unhide it depending on the
6382 enclosing expression.
6384 * spew.c (arbitrate_lookup): #if 0 out.
6386 * decl.c (lookup_name): Never call arbitrate_lookup.
6388 * parse.y (complex_notype_declarator1): Add '*'
6389 complex_notype_declarator1 and '&' complex_notype_declarator1 rules.
6391 * parse.y (complex_direct_notype_declarator): Restore id_scope
6392 see_typename TYPENAME rule, remove all other rules beginning with
6394 (notype_unqualified_id): Add '~' see_typename IDENTIFIER rule.
6396 Thu Mar 17 17:30:01 1994 Jason Merrill (jason@deneb.cygnus.com)
6398 These changes fix the compiler's handling of the functional cast/
6399 object declaration ambiguities in section 6.8 of the ARM. They also
6400 add 11 reduce/reduce conflicts. Sigh.
6402 * parse.y: Add precedence decls for OPERATOR and '~'.
6403 (notype_unqualified_id): New nonterminal, encompasses all of the
6404 ANSI unqualified-id nonterminal except TYPENAMEs.
6405 (expr_or_declarator): New nonterminal to delay parsing of code like
6407 (primary): Use notype_unqualified_id.
6408 (decl): Add typespec initdecls ';' and typespec declarator ';'
6410 (initdcl0): Deal with the above.
6411 (complex_notype_declarator1): A notype_declarator that is not also
6412 an expr_or_declarator.
6413 (complex_direct_notype_declarator): A direct_notype_declarator that
6414 doesn't conflict with expr_or_declarator. Use
6415 notype_unqualified_id. Remove id_scope see_typename TYPENAME rule.
6416 (functional_cast): New nonterminal, for the three functional cast
6417 rules. So that they can be moved after
6418 complex_direct_notype_declarator.
6419 (see_typename): Don't accept type_quals any more.
6421 * decl2.c (reparse_decl_as_expr): New function to deal with parse
6422 nodes for code like `int (*a)++;'.
6423 (reparse_decl_as_expr1): Recursive subroutine of the above.
6424 (finish_decl_parsing): New function to deal with parse nodes for
6425 code like `int (*a);'. See the difference?
6427 Thu Mar 17 12:16:10 1994 Mike Stump <mrs@cygnus.com>
6429 These changes break binary compatibility in code with classes
6430 that use virtual bases.
6432 * search.c (dfs_get_vbase_types): Simplify and correct to make
6433 sure virtual bases are initialized in dfs ordering.
6434 * search.c (get_vbase_types): Simplify and make readable.
6436 Thu Mar 17 12:01:10 1994 Jason Merrill (jason@deneb.cygnus.com)
6438 * parse.y: s/ typename / type_id /g
6440 Wed Mar 16 17:42:52 1994 Kung Hsu (kung@mexican.cygnus.com)
6442 * parse.y (typespec): add SCOPE TYPENAME for global scoped
6445 * decl.c (complete_array_type): fix a bug that in -pendantic
6446 mode even there's no initializer, it will continue to build
6449 Wed Mar 16 17:43:07 1994 Jason Merrill (jason@deneb.cygnus.com)
6451 * parse.y (direct_notype_declarator): Add PTYPENAME rule, remove
6452 all of the scoped PTYPENAME rules.
6454 Wed Mar 16 16:39:02 1994 Mike Stump <mrs@cygnus.com>
6456 * init.c (build_offset_ref): The value of A::typedef_name is
6457 always the TYPE_DECL, and never an error.
6459 Tue Mar 15 20:02:35 1994 Jason Merrill (jason@deneb.cygnus.com)
6461 * search.c (get_base_distance_recursive): Two binfos can only
6462 represent the same object if they are both via_virtual.
6464 * class.c (finish_base_struct): Check vbases for ambiguity, too.
6466 * search.c (get_vbase_types): Accept binfo argument, too.
6468 Tue Mar 15 19:22:05 1994 Kung Hsu (kung@mexican.cygnus.com)
6470 * decl.c (complete_array_type): complete TYPE_DOMAIN of the
6471 initializer also, because back-end requires it.
6473 Tue Mar 15 15:33:31 1994 Jason Merrill (jason@deneb.cygnus.com)
6475 * error.c (dump_expr): Support member functions (which show up as
6478 Mon Mar 14 16:24:36 1994 Mike Stump <mrs@cygnus.com>
6480 * init.c (build_new): Set the return type of multidimensional
6483 Fri Mar 11 15:35:39 1994 Kung Hsu (kung@mexican.cygnus.com)
6485 * call.c (build_method_call): if basetype not equal to type
6486 of the instance, use the type of the instance in building
6489 Thu Mar 10 17:07:10 1994 Kung Hsu (kung@mexican.cygnus.com)
6491 * parse.y (direct_notype_declarator): add push_nested_type for
6492 'template_type SCOPED_NAME' rule.
6494 Tue Mar 8 00:19:58 1994 Jason Merrill (jason@deneb.cygnus.com)
6496 * parse.y (parm): Add typed_declspec1 {absdcl, epsilon} rules.
6498 Sat Mar 5 04:47:48 1994 Jason Merrill (jason@deneb.cygnus.com)
6500 * parse.y (regcast_or_absdcl): New nonterminal to implement late
6501 reduction of constructs like `int ((int)(int)(int))'.
6502 (cast_expr): Use it.
6503 (sub_cast_expr): Everything that can come after a cast.
6504 (typed_declspecs1): typed_declspecs that are not typed_typespecs.
6505 (direct_after_type_declarator): Lose PAREN_STAR_PAREN rule.
6506 (direct_abstract_declarator): Replace '(' parmlist ')' rule with
6507 '(' complex_parmlist ')' and regcast_or_absdcl.
6509 (complex_parmlist): Parmlists that are not also typenames.
6510 (parms_comma): Enabler.
6511 (named_parm): A parm that is not also a typename. Use declarator
6512 rather than dont_see_typename abs_or_notype_decl. Expand
6513 typed_declspecs inline.
6514 (abs_or_notype_decl): Lose.
6515 (dont_see_typename): Comment out.
6516 (bad_parm): Break out abs_or_notype_decl into two rules.
6518 Fri Mar 4 18:22:39 1994 Jason Merrill (jason@deneb.cygnus.com)
6520 * decl2.c (reparse_decl_as_casts): New function to change parse
6521 nodes for `(int)(int)(int)' from "function taking int and returning
6522 function taking int and returning function taking int" to "... cast
6523 to int, cast to int, cast to int".
6525 * decl2.c (reparse_decl_as_expr): Recursive function to change
6526 parse nodes for `A()()' from "function returning function returning
6527 A" to "A().operator()".
6529 * parse.y (primary): Replace `typespec LEFT_RIGHT' rule with
6530 `typespec fcast_or_absdcl' rule.
6531 (fcast_or_absdcl): New nonterminal to implement late reduction of
6532 constructs like `A()()()()'.
6533 (typename): Replace `typespec absdcl1' rule with
6534 `typespec direct_abstract_declarator' rule.
6535 (direct_abstract_declarator): Replace `LEFT_RIGHT type_quals' rule
6536 with `fcast_or_absdcl type_quals' rule.
6538 Fri Mar 4 16:18:03 1994 Mike Stump <mrs@cygnus.com>
6540 * tree.c (lvalue_p): Improve OFFSET_REF handling, so that it
6541 matches Section 5.5.
6543 Fri Mar 4 14:01:59 1994 Jason Merrill (jason@deneb.cygnus.com)
6545 * error.c (dump_type_prefix): Don't print basetype twice for
6548 Fri Mar 4 13:24:33 1994 Mike Stump <mrs@cygnus.com>
6550 * typeck.c (convert_arguments): Handle setHandler(A::handlerFn)
6551 so that it is like setHandler(&A::handlerFn). Cures an `invalid
6552 lvalue in unary `&''.
6554 Fri Mar 4 11:15:59 1994 Jason Merrill (jason@deneb.cygnus.com)
6556 * gxxint.texi (Copying Objects): New section discussing default
6557 op= problems with virtual inheritance.
6559 * decl2.c (grokoptypename): Just does grokdeclarator and
6560 build_typename_overload, since the parser can't call grokdeclarator
6563 * method.c (build_typename_overload): Set IDENTIFIER_GLOBAL_VALUE
6564 and TREE_TYPE on generated identifiers.
6566 * decl.c (grokdeclarator): Don't deal with TYPE_EXPRs anymore.
6568 * parse.y (parm): Convert `const char *' to `__opPCc' here.
6570 * error.c (dump_decl): Say sorry rather than my_friendly_aborting
6571 if we can't figure out what to do.
6572 (dump_type*): Ditto.
6574 * typeck2.c (build_m_component_ref): 'component' is an expr, not
6575 a decl. Also move the IS_AGGR_TYPE check after the stripping of
6578 Fri Mar 4 04:46:05 1994 Mike Stump <mrs@cygnus.com>
6580 * call.c (build_method_call): Handle b->setHandler(A::handlerFn)
6581 so that it is like b->setHandler(&A::handlerFn). Cures an `invalid
6582 lvalue in unary `&''.
6584 Thu Mar 3 12:38:15 1994 Jason Merrill (jason@deneb.cygnus.com)
6586 * parse.y: Add precedence specification for START_DECLARATOR.
6587 (type_quals): Move before primary.
6588 (typename): Move before typed_declspecs, add 'typespec absdcl1' rule.
6590 * decl2.c (grokoptypename): Lose.
6592 * decl.c (grokdeclarator): Parse TYPE_EXPRs in the initial scan,
6593 rather than waiting until later.
6595 Wed Mar 2 14:12:23 1994 Jason Merrill (jason@deneb.cygnus.com)
6597 * parse.y (unary_expr): Use 'typename' in 'new' rules, rather
6598 than expanding it inline.
6599 (typename): Expand empty option of (former) absdcl inline.
6600 (abs_or_notype_decl): Ditto.
6601 (absdcl): Lose empty rule.
6602 (conversion_declarator): New nonterminal for 'typename' of 'operator
6604 (operator_name): Use it instead of absdcl.
6606 * parse.y: Add precedence declarations for SCOPED_TYPENAME,
6608 (typed_declspecs): Accept typed_typespecs, rather than typespec
6609 directly. Add rules with reserved_typespecquals.
6610 (reserved_declspecs): Don't accept typespecqual_reserved at the
6611 beginning of the list. The typed_declspecs rule will deal with this
6613 (declmods): Accept nonempty_type_quals, rather than TYPE_QUAL
6616 * parse.y (direct_notype_declarator,
6617 direct_after_type_declarator, direct_abstract_declarator): Split up
6618 the declarator1 nonterminals to match the draft standard and avoid
6620 (new_type_id, new_declarator, direct_new_declarator,
6621 new_member_declarator): New nonterminals to implement the subset of
6622 'typename' allowed in new expressions.
6623 (unary_expr): Use new_type_id instead of typename.

6627 * parse.y (absdcl1): Don't require parens around
6628 abs_member_declarator.
6629 (abs_member_declarator): Lose see_typename from rules.
6630 (after_type_member_declarator): Ditto.
6632 * tree.c (get_identifier_list): New function, containing code
6633 previously duplicated in get_decl_list and list_hash_lookup_or_cons.
6634 (get_decl_list): Use it.
6635 (list_hash_lookup_or_cons): Ditto.
6637 * parse.y (typed_declspecs, declmods): It's not necessary to hash
6638 the declspecs on class_obstack, so don't. This way typed_typespecs
6639 can reduce to typed_declspecs.
6641 Wed Mar 2 14:29:18 1994 Jason Merrill (jason@cygnus.com)
6643 * cvt.c (build_up_reference): If we aren't checking visibility,
6644 also allow base->derived conversions.
6646 Mon Feb 28 15:14:29 1994 Per Bothner (bothner@kalessin.cygnus.com)
6648 * typeck.c (build_c_cast): Remove bogus hack when converting
6649 to a reference type.
6651 * cp-tree.h (lang_decl::vbase_init_list, DECL_VBASE_INIT_LIST):
6653 (lang_stype::methods, lang_decl::next_method): New fields.
6654 (CLASSTYPE_METHODS, DECL_NEXT_METHOD): New macros.
6655 * decl.c (duplicate_decls): Preserve DECL_NEXT_METHOD.
6657 * cp-tree.h, decl2.c (flag_vtable_hack): New flag.
6658 * decl2.c (finish_vtable_vardecl): If flag_vtable_hack,
6659 and !CLASSTYPE_INTERFACE_KNOWN, try to use the presence of
6660 a non-inline virtual function to control emitting of vtables.
6661 * class.c (finish_struct): Build CLASSTYPE_METHODS list.
6662 * search.c (build_vbase_vtables_init): Don't assemble_external
6663 (yet) if flag_vtable_hack.
6664 * class.c (build_vfn_ref): Ditto.
6666 Mon Feb 28 14:54:13 1994 Jason Merrill (jason@deneb.cygnus.com)
6668 * parse.y (component_decl): Don't include "typed_declspecs
6669 declarator ';'" speedup, since it breaks enums.
6671 Fri Feb 25 15:43:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
6673 * class.c (finish_struct): Minor optimization for building
6676 Fri Feb 25 15:23:42 1994 Jason Merrill (jason@deneb.cygnus.com)
6678 * decl.c (start_function): Fix detection of function overloading.
6680 Thu Feb 24 22:26:19 1994 Mike Stump <mrs@cygnus.com>
6682 * lex.c (check_newline): #pragma interface can take a string
6683 argument, just like #pragma implementation. #pragma implementation
6684 checks for garbage on the line, line #pragma interface does. Main
6685 input files do not auto implement like named files, #pragma
6686 implementation must be used explicitly.
6688 Thu Feb 24 17:09:01 1994 Jason Merrill (jason@deneb.cygnus.com)
6690 * parse.y (components): Handle list of one again.
6691 (notype_components): Ditto.
6692 (after_type_declarator1): Take maybe_raises out again.
6694 * gxxint.texi (Parser): Document additional r/r conflict.
6696 Wed Feb 23 14:42:55 1994 Jason Merrill (jason@deneb.cygnus.com)
6698 * gxxint.texi (Parser): Add node.
6700 * Makefile.in (stamp-parse): Update expected conflict count.
6702 * parse.y (various): Replace "declmods declarator" with "declmods
6703 notype_declarator". The comment saying that "declmods declarator ';'"
6704 corresponds to "int i;" was wrong; it corresponds to "const i;".
6705 (component_decl): Add "typed_declspecs declarator ';'" rule; this
6706 *does* correspond to "int i;". Change "declmods components" to
6707 "declmods notype_components".
6708 (components): Don't deal with a list of one anymore.
6709 (notype_components): New nonterminal, corresponds to notype_declarator.
6710 ({after_,no}type_component_decl{,0}): More new nonterminals.

6712 Eliminates four reduce/reduce conflicts.
6714 (expr): Depend on nontrivial_exprlist instead of nonnull_exprlist.
6715 (nontrivial_exprlist): New nonterminal: A list of at least two
6717 (nonnull_exprlist): Depend on nontrival_exprlist.
6718 Eliminates four reduce/reduce conflicts.
6720 (named_class_head): Move intermediate code block into separate
6721 nonterminal so that we can stick %prec EMPTY on it.
6723 Add more %prec EMPTY's to eliminate remaining shift/reduce
6726 (after_type_declarator): Add maybe_raises to fndecl rules.
6727 (after_type_declarator_no_typename): Remove.
6730 Document remaining reduce/reduce conflicts.
6732 Tue Feb 22 12:10:32 1994 Jason Merrill (jason@deneb.cygnus.com)
6734 * search.c (get_base_distance): Only bash BINFO_INHERITANCE_CHAIN
6735 (TYPE_BINFO (type)) if we care about the path.
6737 * tree.c (lvalue_p): A COND_EXPR is an lvalue if both of the
6740 Mon Feb 21 19:59:40 1994 Mike Stump <mrs@cygnus.com>
6742 * Makefile.in (mostlyclean): lex.c is a source file, don't
6745 Sat Feb 19 01:27:14 1994 Jason Merrill (jason@deneb.cygnus.com)
6747 * parse.y: Eliminate 20 shift/reduce conflicts.
6749 Fri Feb 18 11:49:42 1994 Jason Merrill (jason@deneb.cygnus.com)
6751 * pt.c (type_unification): Add subr argument; if set, it means
6752 that we are calling ourselves recursively, so a partial match is OK.
6753 (unify): Support pointers to methods and functions.
6754 (tsubst): Support method pointers.
6755 * decl.c (build_ptrmemfunc_type): No longer static, so that
6756 tsubst can get at it.
6758 * init.c (is_aggr_typedef): Pretend template type parms are
6760 * decl2.c (build_push_scope): If cname refers to a template type
6761 parm, just grin and nod.
6763 * call.c (build_overload_call_real): Pass subr argument to
6765 * pt.c (do_function_instantiation): Ditto.
6766 * class.c (instantiate_type): Ditto.
6768 * search.c (get_base_distance): If BINFO is a binfo, use it and
6769 don't mess with its BINFO_INHERITANCE_CHAIN.
6771 * cvt.c (convert_to_reference): Fix temporary generation.
6772 If ambiguous, return error_mark_node.
6774 * init.c (build_new): Put back some necessary code.
6776 Thu Feb 17 15:39:47 1994 Jason Merrill (jason@deneb.cygnus.com)
6778 * init.c (build_new): Deal with array types properly.
6780 * search.c (get_binfo): Become a shell for get_base_distance.
6781 (get_binfo_recursive): Lose.
6782 (get_base_distance_recursive): Find the path to the via_virtual base
6783 that provides the most access.
6784 (get_base_distance): Ditto.
6786 * parse.y (explicit_instantiation): Syntax is 'template class
6787 A<int>', not 'template A<int>'.
6789 * typeck.c (convert_for_initialization): Remove bogus warning.
6791 * parse.y (datadef): Revert patch of Oct 27.
6793 Thu Feb 17 15:12:29 1994 Per Bothner (bothner@kalessin.cygnus.com)
6795 * class.c (build_vfn_ref): Cast delta field to ptrdiff_type_node,
6796 rather than integer_type_node. Does wonders for the Alpha.
6798 Thu Feb 17 13:36:21 1994 Jason Merrill (jason@deneb.cygnus.com)
6800 * decl.c (build_ptrmemfunc_type): Make sure that the pmf type
6801 goes onto the same obstack as its target type.
6803 Wed Feb 16 00:34:46 1994 Jason Merrill (jason@deneb.cygnus.com)
6805 * cvt.c (convert_to_reference): If converting via constructor
6806 on local level, go back to build_cplus_new approach.
6808 * tree.c (build_cplus_new): If with_cleanup_p, set cleanup slot
6809 to error_mark_node to prevent expand_expr from building a cleanup
6812 * lex.c (default_assign_ref_body): Return *this from the memcpy
6815 * decl.c (grok_reference_init): Just return if called with
6816 error_mark_node, don't worry about initializing non-const reference
6819 * cvt.c (convert_to_reference): Do the right thing for
6820 non-aggregate reference conversions, pedwarn when generating a
6821 non-const reference to a temporary.
6823 * class.c (finish_struct): TYPE_HAS_COMPLEX_{INIT,ASSIGN}_REF and
6824 TYPE_NEEDS_CONSTRUCTING all depend on TYPE_USES_VIRTUAL_BASECLASSES
6827 Tue Feb 15 19:47:19 1994 Jason Merrill (jason@deneb.cygnus.com)
6829 * decl.c (grok_reference_init): Pawn off a lot of the work on
6830 convert_to_reference. Generally do the right thing.
6832 * cvt.c (convert_to_reference): Conform to the initial comment;
6833 i.e. don't create temps if decl != error_mark_node. Handle
6834 cleanups better for temps that do get created. Don't pretend
6835 that we can use an 'A' to initialize a 'const double &' just by
6836 tacking on a NOP_EXPR. Support LOOKUP_SPECULATIVELY.
6838 * call.c (build_method_call): Set TREE_HAS_CONSTRUCTOR on
6841 Mon Feb 14 14:50:17 1994 Jason Merrill (jason@deneb.cygnus.com)
6843 * decl.c (grok_reference_init): Make a temporary for initializing
6844 const reference from constant expression.
6846 Mon Feb 14 11:31:31 1994 Per Bothner (bothner@kalessin.cygnus.com)
6848 * cp-tree.h, decl.c (set_identifier_local_value): Deleted function.
6849 * decl.c (pushdecl): Define decl in correct binding_level
6850 (which isn't always the inner_binding_level).
6852 * cvt.c (build_up_reference): Don't ever call expand_aggr_init.
6853 It's ugly, and I don't think it's the right thing to do.
6855 * cp-tree.h, class.c, decl.c, decl2.c, sp/search.c:
6856 Remove NEW_CLASS_SCOPING, assuming it is always 1.
6857 * decl.c (pop_decl_level): Removed; manually inlined.
6859 Sun Feb 13 19:04:56 1994 Jason Merrill (jason@deneb.cygnus.com)
6861 * class.h (candidate): Add basetypes field.
6863 * call.c (build_method_call): Do access checking after choosing a
6864 function, not before.

7697 * cp-class.c (modify_other_vtable_entries): Use DECL_ASSEMBLER_NAME
7698 to check if two fndecls are `the same'. Sometimes this routine can

7746 (lang_decode_option): Set warn_return_type, not explicit_*, for
7747 -Wreturn-type and -Wall. This is what rest_of_compilation uses to

7750 * cp-decl.c (grokdeclarator): Use warn_return_type, not explicit_*.

7810 (finish_struct): Ditto. Well, nigh-correctly; it won't deal
7811 properly with the case where a class contains an object of an
7812 ambiguous base class which has a protected op=. Should be fixed
7813 when the access control code gets overhauled.

8139 (build_method_call): When we had some candidates, but didn't get a
8140 usable match, don't report that we got an error with the first
8141 candidate. Instead, say there were no matches, and list the
8142 candidates with print_candidates. In the second pass, make sure we
8143 clear out ever_seen, so we can accurately count the number of
