duck-37 added inline comments.


================
Comment at: llvm/lib/Transforms/IPO/FunctionSpecialization.cpp:305-306
 
-    for (auto *U : Const->users())
-      if (auto *I = dyn_cast<Instruction>(U))
+    // Using replaceUsesWithIf is probably the easiest way to do this without
+    // duplicating code.
+    SmallVector<Instruction *, 8> ReplacedUsers;

That's true, but I'm thinking about holding off on this patch because I think this entire code block might not be needed.
