--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Unless I'm misreading ipa-split.c, it seems it is unprepared to see addressable
retvals with gimple reg type, but where due to the addressability retval is not
is_gimple_val.  Unfortunately, it doesn't seem to be just a single spot, but
tons of them.  I'm afraid with right testcases we could end up e.g. with
addressable int var on the lhs of a call, or as base of a MEM, etc.  Richard,
can you please have a look?
