--- Comment #2 from Uroš Bizjak <ubizjak at gmail dot com> ---
What I find interesting is a similar case with the division instead of the
addition. Clang compiles it to:
divps %xmm1, %xmm0
retq
Considering that we have [a0, a1, 0, 0] / [b0, b1, 0, 0], this will surely fire
invalid operation exception. I have explicitly avoided generation of division
using 4-element DIVPS for v2sf operands exactly due to this issue.
