Timothy Flynn 62b575ad7c LibCrypto: Implement little endian CRC using the slicing-by-8 algorithm ... This implements Intel's slicing-by-8 algorithm for CRC checksums (only little endian CPUs for now, as I don't have a way to test big endian). The original paper for this algorithm seems to have disappeared, but Intel's source code is still available as a reference: https://sourceforge.net/projects/slicing-by-8/ As well as other implementations for reference: https://docs.rs/slice-by-8/latest/src/slice_by_8/algorithm.rs.html Using the "enwik8" file as a test (100MB uncompressed, commonly used in benchmarks: https://www.mattmahoney.net/dc/enwik8.zip), decompression time decreases from: 4.89s to 3.52s on Serenity (cold) 1.72s to 1.32s on Serenity (warm) 1.06s to 0.92s on Linux		2023-03-31 06:56:05 +02:00
