[PATCH] D124193: [AMDGPU] Add WWM reserved VGPRs to existing WWMVGPRs list

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIMachineFunctionInfo.h:473-477
   WWMVGPRsMap WWMVGPRs;
 
+  using ReservedRegSet = SmallSetVector<Register, 8>;
+  // Track VGPRs reserved for WWM.
+  ReservedRegSet WWMReservedRegs;
----------------
I'm confused by the relationship between "WWMReservedRegs" and WWMVGPRs.
