ARM64 Assembly snippets

About

This is a VERY opinioniated snippets extension; it was mainly made for myself to maintain a consistent comment style while taking CSE 320 at Michigan State University, but perhaps other people would also benefit from these snippets.

Prerequisites

This extension requires that either Dan Underwood's Arm Assembly, or maziac's ASM Code Lens, is installed in order for these snippets to work.

Snippets

More snippets will be added soon, for the current snippets available, see below.
