Resubmit r268719 - AMDGPU/SI: Add amdgpu_kernel calling convention. Part 2. This was reverted in r268740 because of problems with corresponding Clang change. Clang change was updated and resubmitted in r274220. Check calling convention in AMDGPUMachineFunction::isKernel This will be used for AMDGPU_HSA_KERNEL symbol type in output ELF. Also, in the future unused non-kernels may be optimized.
