[AMDGPU] Emit debugger prologue and emit the rest of the debugger fields in the kernel code header 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

AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernel Currently the default C calling convention functions are treated the same as compute kernels. Make this explicit so the default calling convention can be changed to a non-kernel. Converted with perl -pi -e 's/define void/define amdgpu_kernel void/' on the relevant test directories (and undoing in one place that actually wanted a non-kernel). llvm-svn: 298444
