James,
There seem to be SPEC CPU2000fp validation issues on A57 when this
flag is present too. Though I evaluated the algorithm with a huge
random set of values, always delivering

James,
ok from our side—good to see that this also benefits the A57.
Best,

Hi,
I've seen a couple of large performance issues caused by expanding
the high-precision reciprocal square root for Cortex-A57, so I'd like
to turn it off by default.
This is good for art (~2%) from Spec2000, bad (~3.5%) for fma3d from
Spec2000, good (~5.5%) for gromcas from Spec2006, and very
10 matches
