--- Comment #4 from Alexandre Oliva <aoliva at gcc dot gnu.org> ---
Mine. Wow, I didn't see that one coming. I thought we only have links from
preserved values to other preserved values, but this proves this is not the
case. A reversal of 208220 will certainly fix that, but I'm assessing the
impact of that on the pr59992 fix, and looking into combining the two table
cleanups at cselib_reset_table into a single pass. I have a hunch there's some
remaining complexity from back when we actually visited each insn twice and had
to roll back cselib table changes.
