This patch adds a new compiler pass aimed at identifying naive CRC
implementations,
characterized by the presence of a loop calculating a CRC (polynomial long
division).
Upon detection of a potential CRC, the pass prints an informational
message.

It is feasible, but it would likely demand considerable effort and

Sorry for the late response; somehow, I didn't receive the last few messages.
