That can happen with AARCH64 SVE and a fixed vector length as noted in r10-5979 and on x86 with AVX512 mask CTORs and trying to re-vectorize using SSE as shown in this bug. The fix is simply to reject the vectorization when it didn't produce the desired type. 2022-02-23 Richard Biener <rguenther@suse.de> PR tree-optimization/101636 PR tree-optimization/104782 * tree-vect-slp.c (vect_slp_analyze_operations): Make sure the CTOR is vectorized with an expected type. * c-c++-common/torture/pr101636.c: Likewise. * gcc.dg/vect/pr104782.c: New testcase. ^ permalink raw reply [flat|nested] 7+ messages in thread
