1905 (make_binding_level): Use ggc_alloc_cleared or memset.
1906 (lookup_tag): Remove struct binding_level* parameter. All
1907 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
1908 current_binding_level->tags if asked for thislevel_only or if
1909 we might have to diagnose "struct foo; union foo;"
1910 (pushlevel): Ignore argument. Do not push another binding
1911 level on the transition from the parameters to the top level
1912 of the function body; just tweak the flags and proceed.
1913 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
1914 a function body, separate the parameter list from the
1915 top-level local variables.
1916 (set_block): Do nothing.
1917 (pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
1918 shadowed_tags if necessary.

1921 (pushdecl): Do not create a shadow entry if we are replacing
1922 an older decl in the same binding level.
1923 (pushdecl_function_level): Tweak for new way of indicating
1925 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
1926 (start_function): Don't set subblocks_tag_transparent.
1927 (finish_function): Fix up the binding_level stack for totally
1928 empty functions. Otherwise, don't call poplevel.
1930 * c-common.c (shadow_warning): MANDATORY argument is no longer
1931 necessary. Always use plain warning.
1932 * c-common.h: Update to match.
1934 * cfglayout.c (scope_to_insns_initialize): Clear block when we
1935 hit the FUNCTION_DECL.
1936 * function.c: Do not create cyclic tree structure.

1960 (c_print_identifier): Update to match changes to struct
1962 (poplevel): Delete #if 0 block. Make externals invisible
1963 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1964 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1965 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1966 (duplicate-decls): For real parm decl after a forward decl,
1967 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1968 foo(...) { } with only a warning. Say whether a previous
1969 declaration was implicit.
1970 (warn_if_shadowing): Now handles all shadowing, not just
1971 local-over-local. Clarify comments.
1972 (pushdecl): Rewritten. There is no longer a distinction
1973 between global and local symbol values; they're all
1974 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1975 DECL_EXTERNAL decls, and use any_external_decl to check
1976 against previous externals. Kill #if 0 blocks. Don't
1977 tolerate error_mark_node being NULL.
1978 (pushdecl_top_level): Handle only those cases which
1979 Objective C (the only user) needs.
1980 (pushdecl_function_level): New function.
1981 (implicitly_declare): Create ordinary decls with
1982 C_DECL_IMPLICIT set. Recycle old decls, however they got

1985 for C_DECL_INVISIBLE symbols.

1993 (identifier_global_value): Same. Must scan
1994 global_binding_level in extremis.
1996 * c-typeck.c (undeclared_variable): New static function, split
1997 from build_external_ref.

2002 IDENTIFIER_GLOBAL_VALUE.
