X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d16d5eac2a0132adcd9e88ae288bedd03abfc513;p=gcc.git

name-lookup.h (pushdecl_with_scope): Replace with ...

	* name-lookup.h (pushdecl_with_scope): Replace with ...
	(pushdecl_outermost_localscope): ... this.
	* name-lookup.c (pushdecl_with_scope): Replace with ...
	(pushdecl_outermost_localscope): ... this.
	(pushdecl_namespace_level): Adjust.
	* decl.c (cp_make_fname_decl): Use pushdecl_outermost_localscope.
	* lambda.c (insert_capture_proxy): Likewise.
