As such don't perform the rewriting if after veclower unless the target supports the operation. If before veclower do the rewriting as well if the target didn't support the original operation either. gcc/ChangeLog: PR tree-optimization/106063 * match.pd: Do not apply pattern after veclower is not supported. gcc/testsuite/ChangeLog: PR tree-optimization/106063 * gcc.dg/pr106063.c: New test.
