Yes, I finally got into this habit, after repeatedly breaking libgomp tests with my patches without noticing it. I also tried to document how to do this at the bottom of this wiki page: https://gcc.gnu.org/wiki/TestCaseWriting It took me a while to figure out how to actually run the Fortran subset of the libgomp suite (which is not very well documented, or I'm too stupid to find it).
