Then you are probably moving in wrong direction worsening the generated code. It is not only performance. The generated code size for x86_64 (SPECInt2000) was 0.5% bigger on the branch before the patch and I am sure it will be even bigger after the patch.

The patch will never be applied. It was not meant to be.

Good because SPECFP2000 for ppc64 is 0.5% better (SPECInt2000 is the same) on the branch than on the mainline at the last merge point. And this patch could remove this achievement.
