--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
We now can move integer operations over to SSE which in some cases (max/min vs.
cmov can be quite a bit faster).  This isolated case is probably not of such
kind (but how can you know w/o benchmarking ...).  On AMD archs the
GPR <-> xmm moves make this unprofitable but those are "free" on intel which
makes costing prefer the pmaxsd variant.
