Browse Source 
* tree-vect-loop-manip.c (slpeel_update_phi_nodes_for_guard1): Don't
	mark phis for renaming.
	* tree-vectorizer.c (vect_memsyms_to_rename): Remove.
	(vectorize_loops): Don't allocate and free vect_memsyms_to_rename.
	Call mark_sym_for_renaming.
	* tree-vectorizer.h (vect_memsyms_to_rename): Remove.
	* tree-vect-loop.c (vect_transform_loop): Remove vect_memsyms_to_rename
	initialization and a call to mark_set_for_renaming.
