The bool
is the signedness of the Integer
type.
One would think we would not care about such details this low down, but some ABIs are described in terms of C types and ISAs where the integer arithmetic is done on {sign,zero}-extended registers, e.g. a negative integer passed by zero-extension will appear positive in the callee, and most operations on it will produce the wrong values.
