Hi Kyle,

The performance results pretty look good so far! (Up to 4% improvement on some SPEC!)
Go ahead with the commit, we will adjust if things turn out to be bad for other workload, but I do not think it will happen.

The only actionable regression on your end is SingleSource/Benchmarks/Misc/ReedSolomon, which regressed by ~4% on x86_64 -O3. Other than that, this is a net win or the regression are within the noise!

Cheers,
-Quentin
