Initialization that's meant to cover all floating-point modes logically should not rely on everything being reachable by the "wider" relation. That is, I'd expect it to do something equivalent to FOR_EACH_MODE_IN_CLASS (mode, MODE_FLOAT) rather than something based on "wider". But if the initialization relies on some form of partial ordering (initializing some modes relies on other modes having been initialized first, in a way somehow related to the "wider" relation), it may be more complicated than that. -- Joseph S.
