[Refactor] Minor DFA optimisation with GetUserCode call

J. Gareth "Kit" Moreton requested to merge CuriousKit/optimisations:GetUserCode-optimisation into main

Summary

This merge request provides a minor speed boost to DFA code by reducing the number of calls to the expensive GetUserCode routine from 2 to 1. This is done by storing the result of the first call and reusing it later (the node tree is not transformed in between the calls).

System

  • Processor architecture: All

What is the current bug behavior?

N/A

What is the behavior after applying this patch?

DFA should be slightly faster.

Relevant logs and/or screenshots

This is a pure refactor and resultant binaries and assembly dumps should not change (except in psub)
