How to get the value of the predicate register?

Hi all,

I have tried many ways to get the value of the predicate register after some instructions say, ISETP. I tried to use “print $P0” to get it as normal registers but it didn’t work. Can someone tell me how should I do it? Or it is missing in cuda-gdb. Thanks in advance!

The predicate registers are not available in cuda-gdb or any CUDA debugger. The API does not expose them.
