Browse Source 
* tree-vectorizer.h (vect_create_data_ref_ptr): Adjust prototype.
	* tree-vect-data-refs.c (vect_create_data_ref_ptr): Add GSI parameter.
	Insert new statements at it in lieu of STMT.
	(vect_setup_realignment): Adjust call to vect_create_data_ref_ptr.
	* tree-vect-stmts.c (vectorizable_store): Likewise.
	(vectorizable_load): Likewise.
