Henry de Valence	6b768c2a1a	Change AVX2 backend to use width-8 tables	2018-04-05 16:20:47 -07:00
Henry & Isis	753a0292de	Rename OddLookupTable to NafLookupTable5. ... An OddLookupTable corresponds to a non-adjacent form of width 5.	2018-04-05 04:48:28 +00:00
Henry de Valence	b0bda0278c	Drop the stdsimd crate in favor of core::{simd, arch}. ... This change required some work, because the to-be-stabilized SIMD functions don't allow non-constant `imm8`s. Previously, the `stdsimd` functions had a constifying macro that ensured that the immediates were known. The dalek code used this to build helper functions which would be inlined into different places where the immediates were known. Unfortunately, since constexprs aren't fully supported in Rust yet, this is done by a hidden compiler attribute, and there's no way to propagate "constness". To deal with this, some of the functions are specialized (e.g., `square_and_negate_D` instead of taking a mask), and others use an enum.	2018-04-03 17:58:23 -07:00
