--- Comment #7 from Bill Schmidt <wschmidt at gcc dot gnu.org> ---
I have a prototype that fixes this in the obvious way and it causes both
slsr-35.c and slsr-36.c to pass again without turning off code hoisting. I'll
do a regstrap and then work on some benchmark testing. I'll post the patch
here for others to try when I get that far.
