[PATCH] D95266: [AMDGPU] Fix FP materialization/resolve with flat scratch

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIRegisterInfo.cpp:443
+    // an SGPR for flat scratch.
+    MRI.setRegClass(BaseReg, &AMDGPU::SReg_32_XEXEC_HIRegClass);
+  }
----------------
I don't think you can blindly set the register class, you should contrainRegClass instead
