1890 (make_binding_level): Use ggc_alloc_cleared or memset.
1891 (lookup_tag): Remove struct binding_level* parameter. All
1892 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
1893 current_binding_level->tags if asked for thislevel_only or if
1894 we might have to diagnose "struct foo; union foo;"
1895 (pushlevel): Ignore argument. Do not push another binding
1896 level on the transition from the parameters to the top level
1897 of the function body; just tweak the flags and proceed.
1898 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
1899 a function body, separate the parameter list from the
1900 top-level local variables.
1901 (set_block): Do nothing.
1902 (pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
1903 shadowed_tags if necessary.
1904 (warn_if_shadowing): Nuke the special case for local shadowing
1906 (pushdecl): Do not create a shadow entry if we are replacing
1907 an older decl in the same binding level.
1908 (pushdecl_function_level): Tweak for new way of indicating
1910 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
1911 (start_function): Don't set subblocks_tag_transparent.
1912 (finish_function): Fix up the binding_level stack for totally
1913 empty functions. Otherwise, don't call poplevel.
1915 * c-common.c (shadow_warning): MANDATORY argument is no longer
1916 necessary. Always use plain warning.
1917 * c-common.h: Update to match.
1919 * cfglayout.c (scope_to_insns_initialize): Clear block when we
1920 hit the FUNCTION_DECL.
1921 * function.c: Do not create cyclic tree structure.

1944 (clone_underlying type): Split out of pushdecl.
1945 (c_print_identifier): Update to match changes to struct
1947 (poplevel): Delete #if 0 block. Make externals invisible
1948 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1949 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1950 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1951 (duplicate-decls): For real parm decl after a forward decl,
1952 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1953 foo(...) { } with only a warning. Say whether a previous
1954 declaration was implicit.
1955 (warn_if_shadowing): Now handles all shadowing, not just
1956 local-over-local. Clarify comments.
1957 (pushdecl): Rewritten. There is no longer a distinction
1958 between global and local symbol values; they're all
1959 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1960 DECL_EXTERNAL decls, and use any_external_decl to check
1961 against previous externals. Kill #if 0 blocks. Don't
1962 tolerate error_mark_node being NULL.
1963 (pushdecl_top_level): Handle only those cases which
1964 Objective C (the only user) needs.
1965 (pushdecl_function_level): New function.
1966 (implicitly_declare): Create ordinary decls with
1967 C_DECL_IMPLICIT set. Recycle old decls, however they got
1969 (lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
1970 for C_DECL_INVISIBLE symbols.

1976 Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
1977 (store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
1978 (identifier_global_value): Same. Must scan
1979 global_binding_level in extremis.
1981 * c-typeck.c (undeclared_variable): New static function, split
1982 from build_external_ref.
1983 (build_external_ref): Use DECL_CONTEXT, not
1984 IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
1985 an instance variable. Restructure for clarity.
1986 * objc/objc-act.c: Use identifier_global_value, not
1987 IDENTIFIER_GLOBAL_VALUE.
