--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
I'll note that we need to sit down and fix this on the costing side, with
costmodel testcases.

There's also still related patches pending which is why I didn't yet start to
investigate any of these cases.

Can we possibly link the same-rev-bisect bugs via see-also?
