Same must be applied to these patch

It's actually a macro, but yes, see the end of
src/mesa/x86/com
How and when is "cpu_has_sse4_1" true? Is it controllable at runtime
through setting some environmental variable? or is it set once during
startup by detecting CPU features?
I guess checking for "cpu_has_sse4_1" is unnecessary if it isn't
controllable by user at runtime; because "USE_SSE41" is

Yes, I'll make sure that happens.

There have been quite a few eyes over this now but nobody has given it a
reviewed by yet.
Would be nice to get it in before the code freeze. Any takers?

Makes use of SSE to speed up compute of min and max elements
Callgrind cpu usage results from pts benchmarks:
Openarena 0.8.8: 3.67% -> 1.03%
UrbanTerror: 2.36% -> 0.81%
V5:
- actually make use of the optimisation in android (Emil Velikov)
- set a better array size limit for using SSE and added
15 matches
