--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- precision is in bits, so it should be likely also something in bits. Could be e.g. MAX_FIXED_MODE_SIZE, that is maximum precision one can get for integral types when not using _BitInt (which indeed can have precision up to 65535 bits). Note, it is certainly useful to have value ranges even for _BitInt(65535) SSA_NAMEs, we just need to avoid spending way too much time on it like in this testcase.
