For each function optimised, up to four implementations will be provided:

* a *scalar* implementation optimised for amd64, but without any SIMD usage,
* a *baseline* implementation using SSE and SSE2 or alternatively an *x86-64-v2* implementation using all SSE extensions up to SSE4.2,
* either a *baseline* implementation using SSE and SSE2, or an *x86-64-v2* implementation using all SSE extensions up to SSE4.2,
