--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- BTW, if we want to put the testcase into the testsuite, maybe we need to tune the exact resx/CLOBBER count, so that even after the fix it doesn't take way too long, but on the other side with unfixed compiler takes long enough to FAIL it at least on slower machines.
