--- Comment #1 from Eric Gallager <egallager at gcc dot gnu.org> ---
Confirmed, although I'm wondering how this is different from bug 78998? Sure,
the original source is slightly different, but they optimize to pretty much the
same thing... doing -fdump-tree-optimized to text files instead of /dev/stdout
and then comparing them gives:
