fearless_simd-v1.1.0

Crates.io | Docs

This release has an MSRV of 1.89.

Added

• Added concat_swizzle_dyn and concat_swizzle_dyn_precise for all non-mask vector types, selecting bytes from the concatenation of two vectors. Out-of-range indices produce implementation-defined values in the former and zero in the latter. (#354 by @​Shnatsel)
• Added compress, compress_merge, expand, and expand_merge for all integer and floating-point vector types. Compression packs mask-selected elements into consecutive low lanes, while expansion places consecutive low elements into mask-selected lanes. Both preserve element order; unused lanes are zeroed or taken from a merge vector. (#395 by @​Novum, @​Shnatsel, #412 by @​RunDevelopment)
• Added MaskWiden and MaskNarrow traits to widen and narrow mask lanes while preserving their boolean values. SimdWiden and SimdNarrow now also guarantee the corresponding conversions for a vector's associated mask, making them available in generic code. (#396, #399 by @​Shnatsel)
• Added SimdMask::from_vector, SimdMask::to_vector, and the associated Ints type for conversions between masks and signed integer vectors. True lanes map to -1 and false lanes to 0; other input values have unspecified behavior. (#400 by @​valadaptive, @​Shnatsel)
• Added lane-wise simd_ne for all vector and mask types. (#408 by @​Shnatsel)
• Added floating-point classification methods is_nan, is_infinite, is_finite, is_subnormal, is_normal, is_sign_positive, and is_sign_negative, returning a mask for each property. (#405 by @​RunDevelopment, @​Shnatsel)
• Added round for floating-point vectors, rounding to the nearest integer with ties away from zero. (#409 by @​RunDevelopment)
• Added to_degrees and to_radians for floating-point vectors. (#406 by @​RunDevelopment)

Changed

• mul_add_precise and mul_sub_precise now use shared SIMD emulation on SSE2 and WebAssembly as well as SSE4.2, improving performance on platforms without native fused multiply-add support. (#394 by @​valadaptive, @​Shnatsel)
• 512-bit dynamic swizzles now use vectorized decomposition on SSE4.2 and WebAssembly. The SSE4.2 swizzle_dyn_precise implementation has also been optimized, and its scalar fallback now avoids branches for unpredictable indices. (#354, #392 by @​Shnatsel)
• Precise f32-to-u32 conversion has been optimized on SSE4.2, and more 32-bit integer/float conversions use SIMD on SSE2. (#404 by @​Shnatsel)
• More 64-bit integer operations now use explicit SIMD implementations on x86 without AVX-512, including comparisons, min/max, multiplication, and right shifts. Multiplication and shifts by runtime values have also been optimized. (#407 by @​Shnatsel)
• Floating-point classification now uses simd_ne where beneficial to improve x86 code generation. (#408 by @​Shnatsel)
• Level::try_detect is now marked inline. (#411 by @​Dr-Emann)

Fixed

• Corrected the mul_add_precise and mul_sub_precise documentation to explain that WebAssembly does not unconditionally provide fused multiply-add support and these operations may be slower there. (#402 by @​valadaptive)
