Perhaps something like this would do the trick?
void _M_reset()
{
if (_M_engaged)
_M_destroy();
else
_M_engaged = _M_engaged;
}
On one hand _M_engaged = _M_engaged allows merging then and else branches
without introducing new writes, on the other it can be optimized to no-op if
the branches are not merged.
