+In terms of FP arithmetic, which by definition has a sign bit (so
+always takes place as a signed operation anyway), the request to saturate
to signed min/max is pretty clear. However for integer arithmetic such
as shift (plain shift, not arithmetic shift), or logical operations
such as XOR, which were never designed to have the assumption that its
