Detailed Description
A feature representing 1 or more stand-alone copies in a basic block.
A COPY operation is considered stand-alone if either a constant or a function input is copied into a location that is then not read directly by the function. These COPYs are incorporated into a single feature, which encodes the number and type of COPYs but does not encode the order in which they occur within the block.
