--- Comment #19 from Jim Wilson <wilson at gcc dot gnu.org> ---
Patch applied to mainline. This is just a minor optimization for gcc-10 as a
combiner patch between gcc-8 and gcc-9 reduces register pressure enough to
prevent the hang. Hence there is no real need for the patch in gcc-9. The
patch might be useful in gcc-8, but the problem is hard to reproduce, buildroot
is the only one that ran into the problem, and they can always add the patch to
their tree, so not clear if we really need it on the gcc-8 branch.
