Commit Message

Li, Pan2 via Gcc-patches July 22, 2022, 7:33 a.m. UTC 
  The following fixes an oversight triggering after the recent change
to bump_vector_ptr.

Bootstrapped on x86_64-unknown-linux-gnu, pushed.

	PR tree-optimization/106387
	* tree-vect-stmts.cc (vectorizable_load): Use make_ssa_name
	if ptr is not an SSA name.
