Sun Aug 22 13:31:44 1993 Brendan Kehoe (brendan@lisa.cygnus.com)
Fix how we handle binding levels, and tweak Niklas's new scoping
code to work 100%. This work should significantly improve how
g++ handles the use of nested classes.
* cp-tree.h (NEW_CLASS_SCOPING): Default to 1 now!
* cp-decl.c (pop_binding_level): Set current_binding_level to be
class_binding_level if it's non-NULL. Change code that looks for
our method of climbing back up the binding levels when we're
dealing with a parm.
(pushlevel_class): Call push_binding_level, not pushlevel.
(poplevel_class): Don't weird out if level is 0. DO NOT set
class_binding_level to the level_chain, this was the biggest bug
that made the pushes and pops to end up being unbalanced.
Call pop_binding_level instead of manually putting the level on
the free_binding_level chain.
(pop_from_top_level): Don't call poplevel if previous_class is
non-NULL.
(finish_function): Call expand_start_bindings and
expand_end_bindings in a balanced way.
(finish_function): Don't flail around screwing with the RTL for
the function in a very special case, just always call
rest_of_compilation as we normally would.
(finish_method): Call poplevel, not pop_binding_level.
* cp-class.c (pushclass): Don't call unuse_fields.
* cp-tree.c (break_out_calls): Always call copy_node, not just
when changed++ == 0.
* cp-search.c (bridge_obstack): Deleted.
(push_class_decls): Use search_obstack, not bridge_obstack.
(init_search_processing): Don't init bridge_obstack anymore.
* cp-init.c (build_new): Don't clear LOOKUP_COMPLAIN on flags, since
we need to honor the visibility of what we find.

running the main GCC program, handle running it under OS/2, MS-DOS,
as well as on a system that has execvp(2). Only find the location
of the GCC executable if we're not using DOS.
* cp-decl.c (poplevel): Only call remember_end_note if we haven't
already created the block. Set TREE_USED on the block.
(duplicate_decls): If the type of either the old or new decl is an
error_mark_node, we've already issued an error so set types_match
to be 1 now.
(xref_defn_tag): Mark the TYPE_DECL as ignored if doing dwarf
debugging.
* cp-parse.y (base_init, nodecls): Call keep_next_level to make
sure the BLOCK node is kept with the outermost curly braces of a
function.
(compstmt): For `{ }', insert a .pushlevel and do all of the other
stuff we need in every other compstmt situation, to generate proper
debugging for such things and handle the binding levels properly for
them.

class scope before trying to push the decl, and then pop back out.
(globalize_nested_type) [NEW_CLASS_SCOPING]: Asserts 348 and 349

Add the changes to redo how we handle scoping. [Merged by bpk.]
* cp-class.c ({pop,push}_nested_class): New functions to use
instead of plain {push,pop}class. These functions will see to
that static entities of enclosing classes will be visible.
* cp-tree.h ({pop,push}_nested_class): Declare them.
* cp-decl.h ({finish,start}_function): Use these new functions
instead of plain {push,pop}class calls.
(grokdeclarator): Ditto.
* cp-decl2.c (build_push_scope): Ditto.
* cp-class.c (popclass): Only call pop_class_decls if MODIFY is
set.
* cp-decl.c (start_decl): Maybe call pushdecl_class_level instead of
pushdecl. This is used for nested types.
(grokdeclarator): Remove the {push,pop}level calls around the
indirect recursion occuring when groking class-local typedefs.
Remove the error check of such typedefs hiding other fields in the
same scope. Remove the pushdecl_class_level call since start_decl
does the work now.
Class scoping (and type value caching) redone. The new behaviour
is triggered by NEW_CLASS_SCOPING being defined to 1. The old
behavior is accomplished by defining it to the value 0. The entries
below describes the effective changes when NEW_CLASS_SCOPING is set
to non-zero.
* cp-class.c (set_class_shadows): Add prototype.
(previous_class_values): New variable.
(pushclass): Adapted to not use previous_class_type & unuse_fields.
Removed setting of IDENTIFIER_CLASS_VALUE.
(popclass): Adapted to not use previous_class_type. Don't reset
IDENTIFIER_CLASS_VALUE. Moved call of pop_class_decls.
(maybe_push_cache_obstack): New function.
* cp-decl.c (current_class_depth): Add extern decl.
(previous_class_values): Add extern decl.
(pop_decl_level): Don't reset IDENTIFIER_CLASS_VALUE.

(poplevel_class): Adjust setting of IDENTIFIER_CLASS_VALUE to only
happen if we're not leaving a toplevel class.
(push_to_top_level): Don't use adjust_type_value.
(set_identifier_type_value): Reverse the choice between class and
local scope when installing the type value.
(set_identifier_local_value): Set the type value if we're seeing a
TYPE_DECL.
(set_nested_typename): Added comment.
(pushtag): Don't call set_identifier_type_value. Leave out
setting of IDENTIFIER_CLASS_VALUE.
(adjust_type_value): Removed.
(pushdecl): Don't call adjust_type_value.
(pushdecl_class_level): Call push_class_level_binding. Set the
type value if we're seeing a TYPE_DECL.
(push_class_level_binding): New function whose guts came from
pushdecl_class_level.
(globalize_nested_type): See to that both the class_shadowed and
type_shadowed lists in the binding stack gets updated correctly.
Don't call set_identifier_type_value on the DECL_NESTED_TYPENAME.
Clear DECL_CLASS_CONTEXT as well as DECL_CONTEXT. Install a
correct IDENTIFIER_{CLASS,TYPE}_VALUE if needed.
(grokdeclarator): Prefer pushdecl_class_level over pushtag when
recording a nested typedef.
(build_enumerator): Don't install a method-local enumerator into
class scope.
* cp-decl2.c (grokfield): Don't call set_identifier_type_value.
* cp-search.c (closed_envelopes): New list containing information
of what decls should be pushed when entering a class scope.
(dfs_pushdecls): Build and maintain the closed_envelopes list
instead of managing the IDENTIFIER_CLASS_VALUEs directly.
(dfs_compress_decls): Adapted to recognize the envelopes
dfs_pushdecls has installed in the IDENTIFIER_CLASS_VALUE slots.
(push_class_decls): Tell overload_template_name to push the
template decls into class scope instead of building a new level.
Added code to open up the envelopes in closed_envelopes and
install the class/type values in the class binding contour with
proper shadowing.
(dfs_popdecls): Removed.
(pop_class_decls): Removed the actual decl-popping code, leaving
just the obstack freeing pop_search_level call. The popping is
automatically handled by poplevel now.
* cp-tree.h (NEW_CLASS_SCOPING): A new macro constant defaulted to
the value 1.
(adjust_type_value): Prototype removed.
(push_class_level_binding): Added prototype.
Wed Jul 7 11:04:09 1993 Brendan Kehoe (brendan@lisa.cygnus.com)
* cp-decl.c (pushdecl): When processing a typedef statement,

looking at isn't an error_mark_node.
* cp-class.c (finish_struct): Set the DECL_CONTEXT on the type we've
found.
* cp-decl.c (pushtag): Mark the TYPE_DECL as ignored when using
dwarf debugging; don't ignore it if it's anonymous for dwarf

the vtable, so we're uniform with what prepare_fresh_vtable is
doing. Introduces a binary incompatability.
* cp-tree.c (build_cplus_method_type): Mark the first argtype (the
this pointer) as artificial.
* cp-init.c (do_friend): Don't allow a friend of a class that's not
yet been defined; instead, complain. Make sure we mark every decl
that comes in as being a friend of something.
* cp-decl2.c (grokclassfn): Mark the __in_chrg parameter as
artificial. Don't mark it as readonly, and for destructors make
sure the first arg in the arg_types chain has TREE_SIDE_EFFECTS set,
so it's seen as artificial.
(finish_vtable_vardecl): For dwarf debugging, make the vtable's
VAR_DECL node be ignored.
* cp-decl.c (redeclaration_error_message): Use comptypes to see if
OLDDECL and NEWDECL have the same type.

Rewrite definitions to not use do/while(0), to avoid bogus warnings
on compilers that can't deal with a return inside it. Change all
uses of them to do `return FOO_RETURN'.
Tue Jul 6 13:00:44 1993 Brendan Kehoe (brendan@lisa.cygnus.com)
* cp-decl.c (duplicate_decls): Set GIVE_ERROR so we know where the
previous declaration was for empty parameter name list declarations.
* cp-class.c (finish_struct): Clean up error message about anonymous
classes.
* cp-class.c (finish_struct): Don't play with TAIL when we're
dealing with a TYPE_DECL of a RECORD_TYPE; the list continues on
just fine, and TAIL is only used for managing FN_FIELDS.
* cp-decl.c (pushlevel): Change cast to HOST_WIDE_INT.
* cp-search.c (breadth_first_search): Likewise.
Fri Jul 2 19:24:55 1993 Steve Chamberlain (sac@rtl.cygnus.com)

`inlinep' and `object' (old object renamed to type), so we can see
where the thing was declared. Use error_with_decl instead of error.

* cp-decl.c (grokdeclarator): Look at the decl as a FUNCTION_TYPE
before seeing if its TYPE_MAIN_VARIANT matches or it's a friend;
this way, we can properly detect declaration of another class's
methods inside another class. Solves chainon aborts.
Tue Jun 29 09:47:36 1993 Brendan Kehoe (brendan@lisa.cygnus.com)
* cp-class.c (finish_struct): Use pedwarn_with_decl for warnings
about non-static const/ref in class without a ctor, so the line
number is helpful.

* cp-search.c (is_subobject_of_p, lookup_field, lookup_fnfields):
Because virtual bases don't necessarily share the same binfo, use
the binfo hierarchy of TYPE_BINFO of any virtual bases, when

storing each character.

identifier names.

clearing of MI_MATRIX.
(get_base_distance): Init NEW_BINFO to 0.
