Yes, I can confirm. The 100% CPU bug is gone on Linux and on Windows. Good Job @ AMD.

gat3way,
Thanks, I can reproduce the issue and I'm looking into it. It actually is the same bug I ran across this morning and been investigating trying to find a solution for.

Gat3way,
A work-around for the crash is to use one of the upper 4 components of chbase in a dummy calculation that doesn't get optimized away. I'm working on a solution so it will be in a future catalyst release. The problem is a crash in the compiler when either a kernel argument gets optimized away or when a 128bit part of a vector argument is not used in the kernel.

Originally posted by: quadboon yes, offline compilations is broken. it either crashes during compilation or the produced binary output fails after reading with clBuildProgram() -11

ignore this, was an problem on my side. all my kernel compile cleanly.

Thanks Micah, I was able to compile successfully without -O0.
