Changes since 1.3.2: - Fix incorrect output from AVX-512 intrinsics under GCC 5.4 and 6.1 in debug mode. This bug was found in unit tests and probably doesn't affect the public API in practice. See https://github.com/BLAKE3-team/BLAKE3/issues/271.

# This crate uses libstd for std::io trait implementations, and also for
|
|
# runtime CPU feature detection. This feature is enabled by default. If you use
|
|
# --no-default-features, the only way to use the SIMD implementations in this
|
|
# crate is to enable the corresponding instruction sets statically for the
|
|
# entire build, with e.g. RUSTFLAGS="-C target-cpu=native".

# The "rayon" feature (defined below as an optional dependency) enables the

# `Hasher::update_rayon` method, for multithreaded hashing. However, even if

|
# this feature is enabled, all other APIs remain single-threaded.

|
# This crate implements traits from the RustCrypto project, exposed here as the
|
|
# "traits-preview" feature. However, these traits aren't stable, and they're
|
|
# expected to change in incompatible ways before they reach 1.0. For that
|
|
# reason, this crate makes no SemVer guarantees for this feature, and callers
|
|
# who use it should expect breaking changes between patch versions of this
|
|
# crate. (The "*-preview" feature name follows the conventions of the RustCrypto
|
|
# "signature" crate.)

|
# By default on x86_64, this crate uses Samuel Neves' hand-written assembly
|
|
# implementations for SSE4.1, AVX2, and AVX512. (These provide both the best
|
|
# runtime performance, and the fastest build times.) And by default on 32-bit
|
|
# x86, this crate uses Rust intrinsics implementations for SSE4.1 and AVX2, and
|
|
# a C intrinsics implementation for AVX-512. In both cases, if a C compiler is
|
|
# not detected, or if AVX-512 support is missing from the detected compiler,
|
|
# build.rs automatically falls back to a pure Rust build. This feature forces
|
|
# that fallback, for testing purposes. (Note that in CI testing, we set the
|
|
# BLAKE3_CI environment variable, which instructs build.rs to error out rather
|
|
# than doing an automatic fallback.)

# default. Enabling the "prefer_intrinsics" feature makes this crate use

# intrinsics implementations on both 32-bit and 64-bit x86, again for testing
|
|
# purposes.

# Disable individual instruction sets. CI testing uses these flags to simulate
|

# different levels of hardware SIMD support. Note that code for the

# corresponding instruction set is still compiled; only detection is disabled.
|
|
#
|
|
# As noted above, these flags are *for testing only* and are not stable. It's
|
|
# possible that some users might find that their particular use case performs
|
|
# better if e.g. AVX-512 is disabled, because of issues like CPU downclocking.
|
|
# If that comes up, and if disabling the instruction set here at the feature
|
|
# level turns out to be the right approach, then we can design a stable
|
|
# feature. Until then, we reserve the right to break these features in a patch
|
|
# release.
