the known to fail section?

This patch is incorrect as -fschedule-insns is enabled at -O2 and

Try -frename-registers.
i forgot to mention: the binaries are compiled with -O3 -mfpmath=sse -msse
(4.2, 4.3 and 4.4).
-frename-registers is enabled by -O3

I don't see how this changes could cause more branch misses. If you do the
same .palign for the 4.4 code does the regression vanish? I would suspect
that the loop-stream detector catches one
