        * target.def (default_libgcc_floating_mode_supported_p): Take
        a scalar_float_mode.
        * doc/tm.texi: Regenerate.
        * targhooks.h (default_floatn_mode): Take a scalar_float_mode.
        * targhooks.c (default_floatn_mode): Likewise.
        * config/aarch64/aarch64.c (aarch64_libgcc_floating_mode_supported_p):
        Likewise.
