[PATCH] D81821: [AMDGPU] Make overlaps with ScratchRSrcReg fatal errors

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIRegisterInfo.cpp:339
   if (StackPtrReg) {
+    if (isSubRegister(ScratchRSrcReg, StackPtrReg))
+      report_fatal_error("scratch resource registers overlap stack pointer");
----------------
This is only really an improvement for hand written MIR, and should go in the verifier?
