This That's the normal expectation for soft-float configurations - that they don't provide exceptions / rounding modes support; the powerpc-nofpu configuration is very much the unusual case. (More broadly, the expectation is that floating-point use in general is fairly limited on soft-float systems; that any heavy uses of floating-point, including anyone concerned with exceptions / rounding modes, would normally be using hardware floating-point arithmetic.) -- Joseph S.
