--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I'd say it is a backend bug.  Canonicalizing (minus:SI (const_int INT_MIN))
into (const_int INT_MIN) is IMNSHO very much desirable, it is just a target bug
that it matches an insn with it at the point where it no longer is able to cope
with it.  So, either it needs to use some predicate which will make such insn
invalid right after split1, or it needs to cope also with the case where during
splitting it can't create pseudos.
