[Mesa-dev] ssbo support missing imin/umin dinstinction

[Ilia Mirkin]

Hi Samuel,

It seems like there's only a single atomic_min intrinsic for ssbo
(same for max), but the ssbo spec actually calls for both signed and
unsigned semantics:

        uint atomicMin(inout uint mem, uint data);
        int atomicMin(inout int mem, int data);

Should there be separate intrinsics for these (and their Max friends)
or is there some other way to tell whether the min/max should be done
signed/unsigned?

Cheers,
