<h2 id="introduction">A Quick Guide to Go's Assembler</h2>

<p>
This document is a quick outline of the unusual form of assembly language used by the <code>gc</code> Go compiler.
The document is not comprehensive.

<p>
The assembler is based on the input style of the Plan 9 assemblers, which is documented in detail
