[PATCH] D99429: [AMDGPU] Save WWM registers in functions

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIFrameLowering.cpp:725
+    auto SpillMI = MBBI;
+    TII->getNamedOperand(*(--SpillMI), AMDGPU::OpName::flags)->setImm(1);
+  }
----------------
I'm not sure what this is setting (I'm also not a huge fan of stepping the iterator back to find the inserted instruction since it spreads the assumption that this only inserts one instruction)
