--- Comment #3 from Uroš Bizjak <ubizjak at gmail dot com> ---
The problem is in i386.c, function expand_vec_perm_blend, where:
/* This matches five different patterns with the different modes. */
x = gen_rtx_VEC_MERGE (vmode, op1, op0, GEN_INT (mask));
x = gen_rtx_SET (target, x);
emit_insn (x);
AVX512F modes need to move mask to a mask register.
