                OS: Linux

llvm/lib/CodeGen/TargetLoweringObjectFileImpl.cpp       1159    err     V763
Parameter 'Offset' is always rewritten in function body before being used.

  // The offset must consider the original displacement from the base symbol
  // since 32-bit targets don't have a GOTPCREL to fold the PC displacement.
  Offset = -MV.getConstant();

Maybe it should be:

  Offset -= MV.getConstant();

?
