The rewriter was previously reading the content buffer from the file itself. Since we are now keeping the content in memory and writing to the file only once, the rewriter's buffer (from the file) was not in sync with the RefactoringTool's buffer. Adding an overrideFileContents call (similar to how Clang-format handles for this) will resolve this issue. Author: Jack Yang <jack.yang@intel.com> Reviewers: gribozavr, klimek llvm-svn: 174643
