--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> 2013-01-07 14:51:26 UTC --- I don't see any differences in assembly, when I compile either version of random.i with -std=gnu99 -fcx-fortran-rules -g -O2 with a r189365 vs. r189366 x86_64-linux -> hppa2.0w-hp-hpux11.11 cross. Can try i686-linux -> hppa2.0w-hp-hpux11.11 cross in case it is HWINT related...
