2025-03-16Rust 1.80 compatibility form `blake3_wasm32_simd`Ivan Boldyrev
2025-03-16Misc textual improvementsIvan Boldyrev
2025-03-16Wasm32 SIMD implementationIvan Boldyrev
This code is based on rust_sse2.rs of the same distribution, and is subject to further improvements. Some comments are left intact even if their applicability is questioned. SIMD implementation is gated by `wasm32-simd` feature, portable version is used otherwise. Performance measurements with a primitive benchmark with ~16Kb of data: | M1 native | 11,610 ns | | M1 WASM SIMD | 13,355 ns | | M1 WASM | 22,037 ns | | x64 native | 6,713 ns | | x64 WASM SIMD | 11,985 ns | | x64 WASM | 25,978 ns | wasmtime v12.0.1 was used on both platforms. Closes #187.

2020-04-13refactor build.rsJack O'Connor
Two main changes: - In https://github.com/BLAKE3-team/BLAKE3/issues/79 we learned that older versions of Clang require AVX-512 flags even to compile AVX-512 assembly. - If the C compiler doesn't support AVX-512, we'd still prefer to build the SSE4.1 and AVX2 assembly implementations, on x86_64.
2020-04-01automatically fall back to the pure Rust buildJack O'Connor
There are two scenarios where compiling AVX-512 C or assembly code might not work: 1. There might not be a C compiler installed at all. Most commonly this is either in cross-compiling situations, or with the Windows GNU target. 2. The installed C compiler might not support e.g. -mavx512f, because it's too old. In both of these cases, print a relevant warning, and then automatically fall back to using the pure Rust intrinsics build. Note that this only affects x86 targets. Other targets always use pure Rust, unless the "neon" feature is enabled.
2020-03-29refactor the Cargo feature setJack O'Connor
The biggest change here is that assembly implementations are enabled by default. Added features: - "pure" (Pure Rust, with no C or assembly implementations.) Removed features: - "c" (Now basically the default.) Renamed features; - "c_prefer_intrinsics" -> "prefer_intrinsics" - "c_neon" -> "neon" Unchanged: - "rayon" - "std" (Still the only feature on by default.)
2020-03-29add a Windows GNU AVX-512 build break workaroundJack O'Connor
The break in question only repros under --release, and we didn't start testing a release build of the prefer-intrinsics mode until just now.
2020-02-14check for AVX-512 compiler support even when using assemblyJack O'Connor
2020-02-12more file renaming, use underscores more consistentlyJack O'Connor
2020-02-12Rename assembly files (blake3-* -> blake3_*)Erik Johansson
This gives the assembly files the same prefix as the intrinsics files which simplifies building when the build system should pick between the assembly and the intrinsics files.
2020-02-12integrate assembly implementations into the blake3 crateJack O'Connor
2020-01-13explicitly check for -mavx512f or /arch:AVX512 supportJack O'Connor
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.

2019-12-12make the "c_avx512" feature a no-op on non-x86Jack O'Connor
This lets us enable it by default in b3sum.
2019-12-11switch to representing CVs as words for the compression functionJack O'Connor
The portable implementation was getting slowed down by converting back and forth between words and bytes. I made the corresponding change on the C side first (https://github.com/veorq/BLAKE3-c/commit/12a37be8b50922a358c016ba07f46816a3da4a31), and as part of this commit I'm re-vendoring the C code. I'm also exposing a small FFI interface to C so that blake3_neon.c can link against portable.rs rather than blake3_portable.c, see c_neon.rs.
