[Piglit] [PATCH] CL/math: Add frexp builtin tests

Mon Feb 1 20:41:47 PST 2016
Add some non-generated float/double tests for the frexp builtin function.
float frexp(float x, int* exp);
The tests are in separate files so that devices that don't support doubles
can still have the float variant tested.
Because the function signature is so unique, I elected to not auto-generate
tests for now.
The double tests don't handle inf/nan, as I couldn't get piglit's CL tester
to interpret those values correctly... Advice welcome.
