<a name="index-command-line-conventions"></a>
|
|
|
|
<p>After the program name <code>as</code>, the command line may contain
|
|
options and file names. Options may appear in any order, and may be
|
|
before, after, or between file names. The order of file names is
|
|
significant.
|
|
</p>
|
|
<a name="index-standard-input_002c-as-input-file"></a>
|
|
<a name="index-_002d_002d"></a>
|
|
<p><samp>--</samp> (two hyphens) by itself names the standard input file
|
|
explicitly, as one of the files for <code>as</code> to assemble.
|
|
</p>
|
|
<a name="index-options_002c-command-line"></a>
|
|
<p>Except for ‘<samp>--</samp>’ any command-line argument that begins with a
|
|
hyphen (‘<samp>-</samp>’) is an option. Each option changes the behavior of
|
|
<code>as</code>. No option changes the way another option works. An
|
|
option is a ‘<samp>-</samp>’ followed by one or more letters; the case of
|
|
the letter is important. All options are optional.
|
|
</p>
|
|
<p>Some options expect exactly one file name to follow them. The file
|
|
name may either immediately follow the option’s letter (compatible
|
|
with older assemblers) or it may be the next command argument (<small>GNU</small>
|
|
standard). These two command lines are equivalent:
