Author: hans Date: Wed Oct 9 02:06:30 2019 New Revision: 374148 URL: http://llvm.org/viewvc/llvm-project?rev=374148&view=rev Log: Unify the two CRC implementations
David added the JamCRC implementation in r246590. More recently, Eugene added a CRC-32 implementation in r357901, which falls back to zlib's crc32 function if present. These checksums are essentially the same, so having multiple implementations seems unnecessary. This replaces the CRC-32 implementation with the simpler one from JamCRC, and implements the JamCRC interface in terms of CRC-32 since this means it can use zlib's implementation when available, saving a few bytes and potentially making it faster. JamCRC took an ArrayRef<char> argument, and CRC-32 took a StringRef. This patch changes it to ArrayRef<uint8_t> which I think is the best choice, and simplifies a few of the callers nicely.
