[PATCH] D136793: [AArch64][GlobalISel] Add some minor post-selection optimizations.

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AArch64/GISel/AArch64PostSelectOptimize.cpp:89
+      continue; // We may have erased this instruction.
+    Changed |= setKillFlags(MI);
+  }
----------------
I'd be disappointed if this is actually helping. Do you have examples where kill flags are needed that aren't added by LiveVariables?
