Debugger prologue is emitted if -mattr=+amdgpu-debugger-emit-prologue. Debugger prologue writes work group IDs and work item IDs to scratch memory at fixed location in the following format: - offset 0: work group ID x - offset 4: work group ID y - offset 8: work group ID z - offset 16: work item ID x - offset 20: work item ID y - offset 24: work item ID z Set - amd_kernel_code_t::debug_wavefront_private_segment_offset_sgpr to scratch wave offset reg - amd_kernel_code_t::debug_private_segment_buffer_sgpr to scratch rsrc reg - amd_kernel_code_t::is_debug_supported to true if all debugger features are enabled Differential Revision: http://reviews.llvm.org/D20335 llvm-svn: 273769
