--- Comment #13 from Dimitry Andric <dim@FreeBSD.org> ---
It's weird, I can find an upstream commit that appears to fix this hang, wh=
ich
is
https://github.com/llvm/llvm-project/commit/56e60bc5bbfb8fdf2b22a897e8801c8=
7771c84e8
("TargetLowering: fix an infinite DAG combine in SimplifySETCC ") but it
appears to have already been applied on llvm 17.0.6.

E.g. I thought I could apply that change and make it work, but now I am hav=
ing
trouble reproducing the original hang. :)
