Why is this commented out? Also the function name is wrong: get_local_offset(). |
| 14 | %z = call i32 @llvm.AMDGPU.read.global.offset.z() nounwind readnone |

| 16 | default: |

This should be implemented in OpenCL C rather than LLVM IR. Now that DataLayouts are mandatory, it makes implementing common code in LLVM IR much more difficult. You can use the builtins defined in your previous patch for this: __builtin_amdgpu_read_global_offset_x ... |
