There is little effect on Intel GPUs now because we almost always take the "always_precise" path first. It may help on other GPUs, and it does prevent a bunch of regressions in "intel/compiler: Don't always require precise lowering of flrp". No changes on any other Intel platforms. GM45 and Iron Lake had similar results. (Iron Lake shown) total cycles in shared programs: 188852500 -> 188852484 (<.01%) cycles in affected programs: 14612 -> 14596 (-0.11%) helped: 4 HURT: 0 helped stats (abs) min: 4 max: 4 x̄: 4.00 x̃: 4 helped stats (rel) min: 0.09% max: 0.13% x̄: 0.11% x̃: 0.11% 95% mean confidence interval for cycles value: -4.00 -4.00 95% mean confidence interval for cycles %-change: -0.13% -0.09% Cycles are helped.
