Well, you need gather loads for that and there you hit PR target/59617. Completely untested patch that let's your testcase be vectorized using 64-byte vectors, for vectorizable_mask_load_store it still punts, but I guess the steps there are first to teach it about non-gather MASK_LOAD and MASK_STORE, which aren't handled for the AVX512F modes either (I think V8DI/V8DF/V16SI/V16SF modes should be possible to handle right now) and then move on to handle the gathers similarly. 2014-01-03 Jakub Jelinek <ja...@redhat.com> PR target/59617 * config/i386/i386.c (ix86_vectorize_builtin_gather): Uncomment AVX512F gather builtins. * tree-vect-stmts.c (vectorizable_mask_load_store): For now punt on gather decls with INTEGER_TYPE masktype.
