With vinfo.vector_mode == VNx4SI mask_type = get_mask_type_for_scalar_type (vinfo, int) mask_type is: vector(4) <signed-boolean:2> I.e. the precision is 2. This is definitely fishy and related to the same problem. I would almost bet that something in the middle-end relies on the precision for some optimization but we just haven't hit it yet. Then we have vector(2) <signed-boolean:4> (precision 4) as a mask type for vector(2) long int. Likewise we would likely have a precision of 8 for a vector(1)? Those might be less severe but still... And that's just what I'm seeing spontaneously after like five minutes. Regards Robin
