<h3 class="section">1.1 Structure of this Manual</h3>

<a name="index-manual_002c-structure-and-purpose"></a>
<p>This manual is intended to describe what you need to know to use
<small>GNU</small> <code>as</code>.  We cover the syntax expected in source files, including
notation for symbols, constants, and expressions; the directives that
<code>as</code> understands; and of course how to invoke <code>as</code>.
</p>
<p>This manual also describes some of the machine-dependent features of
various flavors of the assembler.
</p>
<a name="index-machine-instructions-_0028not-covered_0029"></a>
<p>On the other hand, this manual is <em>not</em> intended as an introduction
to programming in assembly language&mdash;let alone programming in general!
In a similar vein, we make no attempt to introduce the machine
architecture; we do <em>not</em> describe the instruction set, standard
mnemonics, registers or addressing modes that are standard to a
particular architecture.
You may want to consult the manufacturer&rsquo;s
machine architecture manual for this information.
</p>
