Making cross-platform SIMD code pleasant
Summary
The article describes the design and rationale behind the cross-platform, typeless SIMD layer in the bx library. It covers coding style (SSA), data layout for portability, and how ABI differences influence performance, with practical on-ramps like simd32_t and a path from 32-bit lanes to 128/256-bit SIMD. It’s a useful resource for developers aiming to write portable, high-performance SIMD code in C++.
