[PATCH] D151153: [AMDGPU] Add attribute to AMDGPU ctor / dtor to indicate single threadedness

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/AMDGPUCtorDtorLowering.cpp:41
   InitOrFiniKernel->setCallingConv(CallingConv::AMDGPU_KERNEL);
+  InitOrFiniKernel->addFnAttr("amdgpu-flat-work-group-size", "1,1");
   if (IsCtor)
----------------
We should probably teach UniformityAnalysis about this special case for the work item IDs
