I'm currently using supposedly the latest amdgpu-pro driver to write OpenCL codes on W8100 (Hawaii). Our code uses 64-bit atomic_cmpxchg, and
#pragma OPENCL EXTENSION cl_khr_int64_base_atomics : enable
was added to the beginning of the cl code. But the compilation suggests atomic_cmpxchg only accept 32-bit integers, but not 64-bit ones. Is this normal?
