--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Started with r241631 (at least the #c3 testcase). You need -m32 which isn't
entirely obvious from it, and -mcpu=power8 is essential, so either you need gas
with that support around, or e.g. hand-edit auto-host.h to make sure
HAVE_AS_CMPB, HAVE_AS_DFP, HAVE_AS_FPRND, HAVE_AS_POPCNTD, HAVE_AS_POWER8
are defined to 1, then make -j16 cc1.
