LGTM.



================
Comment at: llvm/lib/Target/AMDGPU/SILateBranchLowering.cpp:75
+      AMDGPU::getHasColorExport(F) || AMDGPU::getHasDepthExport(F);
+  bool MustExport = !AMDGPU::isGFX10Plus(TII->getSubtarget());
   // "null export"
----------------
Maybe add a brief comment explaining what changed in the hardware in GFX10?
