Any other bit intrinsics not supported?... I kind of need to know because I'm programming a Radix Sort on CUDA Fortran and I will make heavy use of all of them.

Best Regards,

It will be the same for all of them (btest, iand, ibclr, ibits, ibset, ieor, ior, ishft, ishftc, not) since we don't have the GPU run time device routine. If the intrinsic gets inlined, then it's not a problem.

mmm can I use the "inline" keyword to force it to be inlined?
the ibits one is critical for the radix sort...

When they can be inlined, they are inlined. But the user can't effect this.

I wish I knew off hand the exact circumstance of when each are inlined or not. Though, I'll do some digging on ibits and get back to you.

Word from engineering is that they'll have "btest", "iand", "ibclr", "ibset", "ieor", and "iand" into 12.9. Granted, I haven't verified it myself, but that's the word.
