--- Comment #3 from Florian Weimer <fw at gcc dot gnu.org> ---
I was about to suggest that get_scratch_register_on_entry can spill a register
if no register is available, so maybe we could pass down int_registers_saved to
it and use that approach to avoid the assert.  However, it turns out that this
code is broken, see bug 84128.
