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

<p><a name="index-g_t_002dW-101"></a><a name="index-g_t_002d_002dno_002dwarn-102"></a><a name="index-suppressing-warnings-103"></a><a name="index-warnings_002c-suppressing-104"></a>If you use the <samp><span class="option">-W</span></samp> and <samp><span class="option">--no-warn</span></samp> options, no warnings are issued.
|
|
This only affects the warning messages: it does not change any particular of
|
|
how <samp><span class="command">as</span></samp> assembles your file. Errors, which stop the assembly,
|
|
are still reported.

|
|
files that generate warnings to be in error.
|
|
|
|
<p><a name="index-g_t_002d_002dwarn-108"></a><a name="index-warnings_002c-switching-on-109"></a>You can switch these options off again by specifying <samp><span class="option">--warn</span></samp>, which
|
|
causes warnings to be output as usual.
