c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.

set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't

Objective C (the only user) needs.
