--- Comment #15 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I see SIGILL on
   0x00003fffb7e722e8 <H5T__conv_ulong_float+2744>:     xscvuxdsp vs32,vs33
=> 0x00003fffb7e722ec <H5T__conv_ulong_float+2748>:     stxssp  v0,0(r31)
   0x00003fffb7e722f0 <H5T__conv_ulong_float+2752>:     add     r31,r31,r27
This is in libhdf5 compiled with -mcpu=power8, I believe stxssp is power9
instruction.  Let me try to distill a self-contained testcase.
