Rotating registers are an implementation of hardware registers that are
especially beneficial to loop pipelining ([\#1c6]), as they are indexed
based on the current iteration that the loop is in, which means that
each loop iteration can just write to the same registers, but still
create a pipelined loop, even if there are dependencies between the
pipeline stages.
