const MaxUintptr = ^uintptr(0)

MulUintptr returns a * b and whether the multiplication overflowed. On supported platforms this is an intrinsic lowered by the compiler.

func MulUintptr(a, b uintptr) (uintptr, bool) {
	if a|b < 1<<(4*sys.PtrSize) || a == 0 {
		return a * b, false
	}
	overflow := b > MaxUintptr/a
	return a * b, overflow
