Files are still written only if their content was changed. In addition:

  • If the source file or any file generated from it was changed, the source file is touched, and then the generated files, in that order.
  • If nothing was changed, but a generated file is not newer than the source file, the generated file is touched.

The build system does not know that the source file depends on the files
generated from it, so it did not recompile the source file if only the
generated file was changed.  The generated files are also kept newer
than the source file.
