Nowadays, with each platform (even mobiles) supporting some sort of SIMD registers and operations, it is crucial for every codebase/engine to fully utilize the underlying SIMD functionality. However, SIMD instruction sets, registers and types vary for each platform, and sometimes between compilers as well.

This blog post explains how a platform-agnostic SIMD implementation can be built, without having to port large portions of the codebase for each new supported platform.
