Thu Apr 14 07:15:11 1994 Brendan Kehoe <brendan@lisa.cygnus.com>
* decl.c (push_overloaded_decl): Avoid giving errors about
built-ins, since duplicate_decls will have given warnings/errors
for them.
Thu Apr 14 03:45:12 1994 Jason Merrill <jason@deneb.cygnus.com>
* cvt.c (convert_to_reference): Warn about casting pointer type to
reference type when this is probably not what they wanted.
Wed Apr 13 13:12:35 1994 Per Bothner <bothner@kalessin.cygnus.com>
* decl.c (finish_decl): Don't mindlessly set TREE_USED for

not emit warnings if they are unused).
Wed Apr 13 00:22:35 1994 Jason Merrill <jason@deneb.cygnus.com>
* decl.c (grok_op_properties): If op new/delete get here with
METHOD_TYPEs, do a revert_static_member_fn.

since it doesn't happen any more.

(build_vec_delete): Lose dtor_dummy argument, add use_global_delete,
and pass it to build_x_delete.

the type has a destructor. Pass use_global_delete to
build_vec_delete.
(coerce_delete_type): Make sure that the type returned has a first
argument of ptr_type_node.
* decl.c (init_decl_processing): Also declare the global vec
new/delete.
(grokdeclarator): Also force vec new/delete to be static.
(grok_op_properties): Note presence of vec new/delete, and play with
their args. If vec delete takes the optional size_t argument, set
TYPE_VEC_DELETE_TAKES_SIZE.
* cp-tree.h (TYPE_GETS_{REG,VEC}_DELETE): New macros to simplify
checking for one delete or the other.
(lang_type): gets_new and gets_delete are now two bits long. The
low bit is for the non-array version. Lose gets_placed_new.
(TYPE_VEC_DELETE_TAKES_SIZE): New macro indicating that the vec
delete defined by this class wants to know how much space it is
deleting.
(TYPE_VEC_NEW_USES_COOKIE): New macro to indicate when vec new must
add a header containing the number of elements in the vector; i.e.
when the elements need to be destroyed or vec delete wants to know
the size.

delete.

delete.
* decl.c (grokdeclarator): Correct complaints again.

declarations were in C context. Bash TREE_TYPE (newdecl) here.
(duplicate_decls): Instead of here.
* parse.y (nested_name_specifier_1): Lose rules for dealing with
syntax errors nicely, since they break parsing of 'const i;'.
* decl.c (lookup_name): if (got_scope == current_class_type)
val = IDENTIFIER_CLASS_VALUE (name).
* search.c (lookup_nested_tag): Look in enclosing classes, too.
* spew.c (yylex): Only look one character ahead when checking for a
SCOPE.
* lex.c (check_newline): Read first nonwhite char before
incrementing lineno.
* decl.c (grokdeclarator): Don't claim that typedefs are variables
in warning.
* parse.y: Divide up uses of unqualified_id into
notype_unqualified_id and unqualified_id, so that TYPENAME can be
used as an identifier after an object.
* class.c (push_nested_class): Don't push into non-class scope.
* decl.c (grokdeclarator): If an identifier could be a type
conversion operator, but has no associated type, it's not a type
conversion operator.
* pt.c (unify): Check for equality of constants better.
* decl.c (grokdeclarator): Don't complain about access decls.
Sun Apr 10 02:39:55 1994 Jason Merrill <jason@deneb.cygnus.com>
* decl.c (grokdeclarator): pedwarn about data definitions without
types here.

to get declspecs from some arbitrary $0.
* search.c (lookup_field): Use cp_error.
* parse.y (nested_name_specifier_1): Don't check aggr/non-aggr type
here; it breaks destructors for non-aggr types.
* decl.c (lookup_name): Only look for TYPE_DECLs in base classes of
a type being defined, like the comment says.
If got_scope is not an aggregate, just return NULL_TREE.
* pt.c (create_nested_upt): Kung's code for creating types nested
within uninstantiated templates now lives here (it used to live in
hack_more_ids). It needs to be expanded.
* parse.y: Stop calling see_typename so much.
* decl.c (lookup_name): Deal with TTPs and UPTs.
* lex.c (real_yylex): Don't set looking_for_typename just because we
saw a 'new'.
(dont_see_typename): #if 0 out.
* spew.c (yylex): Increment looking_for_typename if the next
character is SCOPE, rather than setting it to 1; this way, the value
from seeing an aggr specifier will not be lost. This kinda relies
on looking_for_typename never being < 0, which is now true.
* parse.y (nested_name_specifier_1): Accept TEMPLATE_TYPE_PARMs,
too.
(named_class_head_sans_basetype): Accept template types, too. Oops.
Fri Apr 8 16:39:35 1994 Jason Merrill <jason@deneb.cygnus.com>

* parse.y: Lose START_DECLARATOR.
* search.c (lookup_nested_tag): New function to scan CLASSTYPE_TAGS
for a class.

* decl2.c (groktypefield): #if 0 out.
* decl.c (lookup_name): If the type denoted by got_scope is
currently being defined, look in CLASSTYPE_TAGS rather than FIELDS.

error_mark_node.
Fri Apr 8 07:26:36 1994 Brendan Kehoe <brendan@lisa.cygnus.com>
* Makefile.in (stamp-parse): Update count of conflicts to 33.
Thu Apr 7 17:47:53 1994 Jason Merrill <jason@deneb.cygnus.com>
A saner implementation of nested types that treats template types
no differently from non-template types. There are still some
shortcomings of our system; most notably, it is difficult to look
for a nested type that is hidden by another name, because of the way
we keep track of hidden types. But this shouldn't be a problem for
just about anyone. Perhaps lookup_field should be fixed up a bit.
* spew.c: Moved handling of nested types/scoping from the lexer
into the parser. Removed variable template_type_seen_before_scope.
Removed functions frob_identifier, hack_more_ids, and various cruft
that was #if 0'd out in the past, reducing the size of the file from
1146 lines to 450 lines. We can't quite do away with spew.c yet,
though; we still need it for do_aggr () and checking for SCOPE after
the current identifier. And setting lastiddecl.
* parse.y: Moved handling of nested types/scoping from the lexer
into the parser, using a new global variable `got_scope'. Reduced
the number of states by 53. Implemented all uses of explicit global
scope. Removed terminals SCOPED_TYPENAME and SCOPED_NAME. Removed
nonterminals tmpl.1, scoped_base_class, id_scope, typename_scope,
scoped_typename. Added nonterminals nested_type,
qualified_type_name, complete_type_name, qualified_id, ptr_to_mem,
nested_name_specifier, global_scope, overqualified_id, type_name.
Changed many others. Added 9 new reduce/reduce conflicts, which are
nested type parallels of 9 that were already in the grammar for
non-nested types. Eight of the now 33 conflicts should be removed
in the process of resolving the late binding between variable and
function decls.
* gxxint.texi (Parser): Update.
* cp-tree.h (IS_AGGR_TYPE_CODE): Add UNINSTANTIATED_P_TYPE.
* lex.h: Add decl for got_scope.
* lex.c (see_typename): Claim to be the lexer when calling
lookup_name.
* decl.c (lookup_name): When called from the lexer, look at
got_scope and looking_at_typename; otherwise don't.
Thu Apr 7 22:05:47 1994 Mike Stump <mrs@cygnus.com>

Wed Apr 6 16:05:10 1994 Per Bothner <bothner@kalessin.cygnus.com>
* init.c (build_virtual_init), search.c (build_vbase_vtables_init),
ch-tree.h: Every place these functions were called, the result was
immediately passed to expand_expr_stmt. Reduce redundancy by
calling expand_expr_init *inside* these functions. These
makes for a simpler interface, and we don't have to build
compound expressions. Hence, rename these function to:
expand_virtual_init and expand_vbase_vtables_init respectively.
* init.c, decl.c: Change callers of these functions.
* init.c, cp-tree.h (expand_virtual_init): Make static.
* decl2.c (finish_file): Check TREE_PUBLIC||TREE_ADDRESSABLE

the value of strict_prototypes for DECL_LANGUAGE (oldecl).

* decl.c (init_decl_processing): if (flag_ansi || pedantic)
strict_prototypes_lang_c = strict_prototypes_lang_cplusplus;
* decl2.c (grok_function_init): Don't set DECL_INITIAL on pure
virtuals.

If using thunks, the latter is just ptr_type_node.
* gc.c, typeck.c: Use memptr_typeChange, not vtable_entry_type.
* decl2.c (finish_vtable_vardecl): Handle thunks.
* expr.c (cplus_expand_expr): Support THUNK_DECL.

* decl2.c (pending_addressable_inlines): Renamed to saved_inlines.
* decl2.c (mark_inline_for_output): Do nothing if
DECL_SAVED_INLINE; otherwise set it (and add to saved_inlines list).
* decl2.c (finish_vtable_vardecl): SET_CLASSTYPE_INTERFACE_KNOWN
and set CLASSTYPE_INTERFACE_ONLY if there is a non-inline virtual.
* decl2.c (finish_file): Writing out inlines later, so we can
also handle the ones needed for vtbales.
* decl2.c (write_vtable_entries, finish_vtable_typedecl): Removed.
* cp-tree.h, class.c, decl2.c, search.c: Remove -fvtable-hack
and flag_vtable_hack. Use -fvtable-thunks and flag_vtable_thunks
instead. (The rationale is that these optimizations both break binary
compatibility, but should become the default in a future release.)
Wed Apr 6 10:53:56 1994 Mike Stump <mrs@cygnus.com>
* class.c (modify_vtable_entries): Never reset the DECL_CONTEXT
of a fndecl, as we might not be from that vfield.

* typeck.c (c_expand_return): Before checking that we're not
returning the address of a local, make sure it's a VAR_DECL.

Mon Apr 4 11:28:17 1994 Kung Hsu <kung@mexican.cygnus.com>

RTL point to abort, then put in virtual table.

Sat Apr 2 03:12:58 1994 Jason Merrill <jason@deneb.cygnus.com>

* tree.c (get_identifier_list): Only do the special handling
thing if we're dealing with the main variant of the record type.
* cvt.c (convert_to_reference): When converting between
compatible reference types, use the pointer conversion machinery.
Don't just blindly overwrite the old type.
Fri Apr 1 17:14:42 1994 Jason Merrill <jason@deneb.cygnus.com>
* call.c (build_method_call): When looking at global functions,
be sure to use instance_ptr for the first argument, not some version

an expr_or_declarator.

doesn't conflict with expr_or_declarator. Use
notype_unqualified_id. Remove id_scope see_typename TYPENAME rule.
(functional_cast): New nonterminal, for the three functional cast
rules. So that they can be moved after
complex_direct_notype_declarator.
(see_typename): Don't accept type_quals any more.

nodes for code like `int (*a)++;'.
(reparse_decl_as_expr1): Recursive subroutine of the above.

code like `int (*a);'. See the difference?

default index.
Wed Mar 16 17:43:07 1994 Jason Merrill <jason@deneb.cygnus.com>
