--- Comment #3 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
This is a bug in peep2_find_free_register() which fails to correctly validate
that second and subsequent registers in a multi-register mode are available for
use.
Marked as a regression since this code would have worked correctly on older
compilers.
