I see that clang creates a temporary file when generating bc/ll/.o files

is complete. Any reason why a temporary file is needed here ?

CompilerInstance::createDefaultOutputFile(bool Binary,
                                          StringRef InFile,
                                          StringRef Extension) {
  return createOutputFile(getFrontendOpts().OutputFile, Binary,
                          /*RemoveFileOnSignal=*/true, InFile,
