================
Comment at: include/llvm/Analysis/ValueTracking.h:179
+  bool SignBitMustBeZero(const Value *V, const TargetLibraryInfo *TLI,
+                         unsigned Depth = 0);
+
----------------
Minor tweak: Depth is never explicitly passed in, so might as well get rid of the argument.
