<h3 class="section">1.1 Structure of this Manual</h3>
|
|
|
|
<p><a name="index-manual_002c-structure-and-purpose-21"></a>This manual is intended to describe what you need to know to use
|
|
<span class="sc">gnu</span> <samp><span class="command">as</span></samp>. We cover the syntax expected in source files, including
|
|
notation for symbols, constants, and expressions; the directives that
|
|
<samp><span class="command">as</span></samp> understands; and of course how to invoke <samp><span class="command">as</span></samp>.
|
|
|
|
<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_0029-22"></a>On the other hand, this manual is <em>not</em> intended as an introduction
|
|
to programming in assembly language—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's
|
|
machine architecture manual for this information.

<!-- There used to be a section "Terminology" here, which defined -->
|
|
<!-- "contents", "byte", "word", and "long". Defining "word" to any -->
|
|
<!-- particular size is confusing when the .word directive may generate 16 -->
|
|
<!-- bits on one machine and 32 bits on another; in general, for the user -->
|
|
<!-- version of this manual, none of these terms seem essential to define. -->
|
|
<!-- They were used very little even in the former draft of the manual; -->
|
|
<!-- this draft makes an effort to avoid them (except in names of -->
|
|
<!-- directives). -->
