https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78775 --- Comment #11 from Martin Sebor --- I've raised bug 79073 for the gcc.dg/pr78973.c failure. AFAICT, it's due to a VRP defect or limitation.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78775 --- Comment #3 from Marek Polacek --- 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?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78775 --- Comment #2 from Marek Polacek --- We're in operand_signed_p, checking whether an SSA_NAME d_4 is signed or not. We look at its SSA_NAME_DEF_STMT which is d_4 = PHI <0(2), d_5(5)> and we walk these phi arguments, and we call operand_signed_p
