Subject: Remove DR_GROUP_STORE_COUNT
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=49431232988d8294bc351ff2edcaad8fce088b70;p=thirdparty%2Fgcc.git

Remove DR_GROUP_STORE_COUNT

This was only used for non-SLP.

	* tree-vectorizer.h (_stmt_vec_info::store_count): Remove.
	(DR_GROUP_STORE_COUNT): Likewise.
	* tree-vect-stmts.cc (vect_transform_stmt): Remove non-SLP
	path.
