Jack O'Connor 14cd5c51c4 version 0.1.2 
Changes since 0.1.1:
- b3sum no longer mmaps files smaller than 16 KiB. This improves
  performance for hashing many small files. Contributed by @xzfc.
- b3sum now supports --raw output. Contributed by @phayes.

Jack O'Connor 02250a7b7c version 0.1.1 
Changes since 0.1.0:
- Optimizations contributed by @cesarb.
- Fix the build on x86_64-pc-windows-gnu when c_avx512 is enabled.
- Add an explicit error message for compilers that don't support c_avx512.
 2020-01-13 14:47:28 -05:00
Jack O'Connor caa6622afa explicitly check for -mavx512f or /arch:AVX512 support 
If AVX-512 is enabled, and the local C compiler doesn't support it, the
build is going to fail. However, if we check for this explicitly, we can
give a better error message.

Fixes https://github.com/BLAKE3-team/BLAKE3/issues/6.

Cesar Eduardo Barros 9f509a8f1f Inline trivial functions 
For the Read and Write traits, this also allows the compiler to see that
the return value is always Ok, allowing it to remove the Err case from
the caller as dead code.
 2020-01-12 18:27:42 -05:00
Cesar Eduardo Barros 4690c5f14e Use fixed-size constant_time_eq 
The generic constant_time_eq has several branches on the slice length,
which are not necessary when the slice length is known. However, the
optimizer is not allowed to look into the core of constant_time_eq, so
these branches cannot be elided.

Use instead a fixed-size variant of constant_time_eq, which has no
branches since the length is known.

Jack O'Connor b04974461a include the right context string in the test_vectors.json comment 
I must've written the comment one way, and then changed the context
string later, without realizing that I'd copied it. Apologies to
everyone whose time I wasted with this.

Fixes https://github.com/BLAKE3-team/BLAKE3/issues/15.
 2020-01-12 17:07:23 -05:00
Jack O'Connor 793c8a2444 disambiguate the two test 
We can't change the context used in test_vectors.json without breaking
people, but we can change the one in unit tests.
