LGTM.

> And here's some timings comparing BLAKE3 with LLVM's SHA1/SHA256/MD5. The table shows the speed-up multiplier of BLAKE3 for hashing 100 MBs:

It will be worth mentioning which optimized implementation is used for Intel Xeon W and M1Pro, respectively.

The performance of using the generic implementation is also interesting. None of LLVM's SHA1/SHA256/MD5 libraries is well optimized.
