Richard Henderson ce8d408205 fpu: Bound increment for scalbn ... Without bounding the increment, we can overflow exp either here in scalbn_decomposed or when adding the bias in round_canonical. This can result in e.g. underflowing to 0 instead of overflowing to infinity. The old softfloat code did bound the increment.
