The CPUs implying soft-float are the ones using MASK_SOFT_FLOAT in rs6000-cpus.def. If you follow MULTILIB_MATCHES_FLOAT, at least you won't be making things wrong in any case that currently works properly (but confirming the correctness of MULTILIB_MATCHES_FLOAT would certainly be good). -- Joseph S.
