I've raised bug 79073 for the gcc.dg/pr78973.c failure. AFAICT, it's due to a

Thanks for the heads up, Bill. I opened bug 79051 for the failure. Can you
paste the excess error(s) you see into that bug please? (I don't see any in my
builds.)

So either some games with TREE_VISITED, or keep some hash_set of visited
SSA_NAMEs, or when scanning the PHI arguments, check whether its argument's
definition is also a PHI and has OP in it?
