[PATCH] D47509: [AMDGPU] Track occupancy in MFI

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

The problem with this is until we can serialize MachineFunctionInfo, this is going fo further degrade MIR tests.



================
Comment at: lib/Target/AMDGPU/SIISelLowering.cpp:4258-4262
+    SDValue Res = AMDGPUTargetLowering::LowerGlobalAddress(MFI, Op, DAG);
+    MachineFunction &MF = DAG.getMachineFunction();
+    SIMachineFunctionInfo *MFI = MF.getInfo<SIMachineFunctionInfo>();
+    MFI->limitOccupancy(MF);
+    return Res;
----------------
Why is this here?
