Yes, this pass can detect only bitwise (naive) implementations of CRC32C
and replace them with hardware crc32* instructions (if supported), or
alternatively
generate CRC using CLMUL-based or table-based methods.
Here is an example of such a CRC32C implementation, where the entire loop
will be repla

Hello!
This patch set detects bitwise CRC implementation loops (with branches) in
the GIMPLE optimizers and replaces them with more optimal CRC
implementations in RTL. These patches introduce new internal functions,
built-in functions, and expanders for CRC generation, leveraging hardware
