--- Comment #14 from Martin Liška <marxin at gcc dot gnu.org> --- > How do you reduce a gcda file together with the original source? I did it in 2 steps. I first reduced the source file and then I wrote an experimental binary reducer that removes GCDA function entries. > For testsuite, it would be best if we could turn it into a self-contained > runnable testcase which we could train and then ICE (or with fixed compiler > compile). Yes, that would be nice.
