rnk added inline comments.
================ Comment at: clang/lib/Frontend/CompilerInstance.cpp:857-858 + OS.reset(new llvm::raw_fd_ostream(Temp->FD, /*shouldClose=*/false, + Binary ? llvm::sys::fs::OF_None + : llvm::sys::fs::OF_Text)); + OSFile = std::string(TempPath.str()); ---------------- I think the bug is here: the third parameter is `bool unbuffered`, not file flags, so we are opening the file for unbuffered writing, and that is really slow.
