--- Comment #1 from Marc Glisse <glisse at gcc dot gnu.org> ---
This was missing a simple testcase, but now we can write one (in C++):
typedef int vec __attribute__((vector_size(32)));
vec f(vec x){
return x<0?2:1;
}
vpxor %xmm1, %xmm1, %xmm1
vpcmpgtd %ymm0, %ymm1, %ymm1
vmovdqa .LC1(%rip), %ymm0
vpblendvb %ymm1, .LC0(%rip), %ymm0, %ymm0
IIUC, we could skip vpcmpgtd and pass ymm0 directly to vpblendvb.
