[PATCH] D37460: [GVN] Prevent LoadPRE from hoisting through guards

[Eli Friedman via Phabricator via llvm-commits]

efriedma added inline comments.


================
Comment at: lib/Transforms/Scalar/GVN.cpp:2042
+    auto *II = dyn_cast<IntrinsicInst>(&I);
+    return II && II->getIntrinsicID() == Intrinsic::experimental_guard;
+  };
----------------
Why does this specifically apply to guards, as opposed to anything where isGuaranteedToTransferExecutionToSuccessor() is false?
