--- Comment #6 from Vladimir Makarov <vmakarov at gcc dot gnu.org> ---
I've decided to fix it in RA because it could help to fix analogous bugs when
existing hard reg splitting code fails. This particular bug is more complicated
because it happens for non-small reg class. It requires a lot of changes in
LRA and changing its sub-pass flow.
I've been working on this PR for some time and now I can say that it will
probably fixed on this week.
