Subject: tree.c (get_fns): Split out from get_first_fn.
X-Git-Tag: upstream/12.2.0~93461
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=294e855f96883c225bb8961eb456d8f770bdf41a;p=platform%2Fupstream%2Fgcc.git

tree.c (get_fns): Split out from get_first_fn.

	* tree.c (get_fns): Split out from get_first_fn.
	* cp-tree.h: Declare it.
	* search.c (shared_member_p): Use it.
	* semantics.c (finish_qualified_id_expr): Simplify.
	(finish_id_expression): Simplify.
