[Mesa-dev] [PATCH V5] mesa: add SSE optimisation for glDrawElements

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 a compile time 
check and requires the target machine to be SSE 4.1 capable already.

Best regards,
