Comment at: llvm/lib/Target/AMDGPU/Utils/AMDGPUBaseInfo.cpp:439
   // SGPRBlocks is actual number of SGPR blocks minus 1.
-  return NumSGPRs / getSGPREncodingGranule(STI) - 1;
+  unsigned NumSGPRBlocks = divideCeil(NumSGPRs, Alignment) - 1;
+  return isGFX9(*STI) ? NumSGPRBlocks * 2 : NumSGPRBlocks;
