[PATCH] D26391: [JumpThreading] Unfold selects that depend on the same condition

[Eli Friedman via llvm-commits]

efriedma added inline comments.


================
Comment at: llvm/trunk/lib/Transforms/Scalar/JumpThreading.cpp:2053
+      std::sort(Selects.begin(), Selects.end());
+      auto NewEnd = std::unique(Selects.begin(), Selects.end());
+
----------------
This needs a large comment explaining why sorting by pointer addresses doesn't introduce non-determinism.
