An example of duplicated code in Clang (it appears in llvm/tools/clang/lib/Frontend/Rewrite/RewriteMacros.cpp starting from line 128):

  // If this is a #warning directive or #pragma mark (GNU extensions),
  // comment the line out.
  if (RawTokens[CurRawTok].is(tok::identifier)) {
    const IdentifierInfo *II = RawTokens[CurRawTok].getIdentifierInfo();
    if (II->getName() == "warning") {
      // Comment out #warning.
      RB.InsertTextAfter(SM.getFileOffset(RawTok.getLocation()), "//");       // THIS IS...
    } else if (II->getName() == "pragma" &&
               RawTokens[CurRawTok+1].is(tok::identifier) &&
               (RawTokens[CurRawTok+1].getIdentifierInfo()->getName() ==
                "mark")) {
      // Comment out #pragma mark.
      RB.InsertTextAfter(SM.getFileOffset(RawTok.getLocation()), "//");       // IDENTICAL TO THIS
    }
  }
