Package archsimd provides access to architecture-specific SIMD operations.
This is a low-level package that exposes hardware-specific functionality. It currently supports AMD64.
This package is experimental, and not subject to the Go 1 compatibility promise. It only exists when building with the GOEXPERIMENT=simd environment variable set.
