I can attempt to handle that now... It'll just take a bit of research on
my part. The AMD implementation of float erf assumes that you have support
for doubles when the device doesn't support subnormals. I'm not sure that
this is a safe assumption to make, so we'll probably want/need to find some
other way to deal with that situation.
I can at least surround the existing implementation with an #if
defined(cl_khr_fp64) && !defined(SUBNORMALS_SUPPORTED)), and we'll just
have to have an else if for !SUBNORMALS && !DOUBLES.
