No, it's a toplevel function. > It is theoretically safe to call set_ssa_to_val with to == vn_top, but > it's probably a bug somewhere, and i'd rather eliminate the bug cases > before turning it off. visit_phi is called on a PHI node with 1 argument (shrinked by DOM): # NMT.152_89(ab) = PHI <NMT.152_264(ab)(22)> and the SSA_VAL of NMT.152_264 is VN_TOP. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32705
