I have problems compiling my some of my kernels for AMD GPUs, no problems with NVDIA OpenCL.


Used platform OpenCL 1.2 AMD-APP (1084.4) Juniper HD5700 Win7-64.


Minimal kernel extracted from bigger one as example:


kernel void AMDBug (const uint xx, global uint *gg) {
   uint x = get_global_id(0) + xx;
   if (x < xx) *gg = 1;


Compiler crashed when compiling for GPU, no problem for CPU.

Last message before crash:

LLVM ERROR: Cannot select: 0xb1e670: i8 = setcc <lots of hex codes>


Please your advice.

Best regards, Jaap.
