|
|
<p><code>as</code> should never give a warning or error message when
|
|
assembling compiler output. But programs written by people often
|
|
cause <code>as</code> to give a warning that a particular assumption was
|
|
made. All such warnings are directed to the standard error file.
|
|
</p>

<a name="index-warnings_002c-suppressing"></a>
|
|
<p>If you use the <samp>-W</samp> and <samp>--no-warn</samp> options, no warnings are issued.
|
|
This only affects the warning messages: it does not change any particular of
|
|
how <code>as</code> assembles your file. Errors, which stop the assembly,
|
|
are still reported.
|
|
</p>

<a name="index-errors_002c-caused-by-warnings"></a>
|
|
<a name="index-warnings_002c-causing-error"></a>
|
|
<p>If you use the <samp>--fatal-warnings</samp> option, <code>as</code> considers
|
|
files that generate warnings to be in error.
|
|
</p>
|
|
<a name="index-_002d_002dwarn"></a>
|
|
<a name="index-warnings_002c-switching-on"></a>
|
|
<p>You can switch these options off again by specifying <samp>--warn</samp>, which
|
|
causes warnings to be output as usual.
