From what I can see, gcc has been using OImode in this testcase since it was changed to pass 32-byte vectors in ymm registers (somewhen during 4.4 development, and 4.3 didn't have avx support at all). Thus this doesn't look any kind of regression to me. We risk ABI regressions if we change this though.
