[Bug target/38825] missed optimization: register renaming in unrolled loop



------- Comment #2 from rguenth at gcc dot gnu dot org  2009-01-13 15:15 -------
Note that your testcase has moved the load _mm_load_ps(in+4); before the
store _mm_store_ps(out, result); which the compiler cannot do itself because
they may alias.
