Hi, Some of the recently added vectorizer pattern detection functions create pattern def stmts, and set vectype for these statements. This causes an assert failure in vect_determine_vectorization_factor, since we only expect data-refs and pattern statements themselves to have the vectype set. This patch updates the assert.
Bootstrapped on powerpc64-suse-linux and tested on powerpc64-suse-linux and x86_64-suse-linux. Committed.
