    atom_xchg and atom_cmpxchg won't compile



      There appears to be a serious bug in the AMD OpenCL compiler.  It simply fails to compile any kernel involving atom_xchg, atom_cmpxchg, atomic_xchg, or atomic_cmpxchg.  Other atomic functions work fine.  Can anyone shed some light on this?

      #pragma OPENCL EXTENSION cl_khr_global_int32_base_atomics : enable __kernel void Test(volatile __global int *output) { atom_xchg(output, 0); }
