If there is one thing that’s completely banned from the Molecule Engine, it’s dynamic strings. I’ve always cringed at how many string operations and string-based look-ups where done in the last codebase I’ve been working with, hence I wanted to get completely rid of them in the run-time part of the engine – no exceptions.
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.
