[PATCH] D128583: CodeGen: Remove AliasAnalysis from regalloc

[Mircea Trofin via Phabricator via llvm-commits]

mtrofin added inline comments.


================
Comment at: llvm/lib/CodeGen/MLRegallocEvictAdvisor.cpp:890
 bool RegAllocScoring::runOnMachineFunction(MachineFunction &MF) {
+  AA = &getAnalysis<AAResultsWrapperPass>().getAAResults();
+
----------------
I think this isn't needed here.


================
Comment at: llvm/lib/CodeGen/MLRegallocEvictAdvisor.cpp:898
               MF, getAnalysis<MachineBlockFrequencyInfo>(),
               getAnalysis<AAResultsWrapperPass>().getAAResults())
               .getScore()));
----------------
this can be removed, since calculateRegAllocScore now doesn't need the AA
