Implement isinf/isnan #922

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Implement isinf/isnan

genBType isnan (genType x)
Returns true if x holds a NaN. Returns false otherwise.

genBType isinf (genType x)
Returns true if x holds a positive infinity or negative infinity. Returns false 
otherwise.

HLSL intrinsic functions for the same are there already, looks like we only 
need to provide the mapping.
