--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-07-19 11:29:27 UTC --- Created attachment 27832 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27832 gcc48-pr54017.patch Untested fix. Though, of course, the testcase is very questionable when omp section doesn't exit, then the region is not single entry single exit.
