<p><a name="index-g_t_002df-59"></a><a name="index-trusted-compiler-60"></a><a name="index-faster-processing-_0028_0040option_007b_002df_007d_0029-61"></a>‘<samp><span class="samp">-f</span></samp>’ should only be used when assembling programs written by a
|
||
|
|
(trusted) compiler. ‘<samp><span class="samp">-f</span></samp>’ stops the assembler from doing whitespace
|
||
|
|
and comment preprocessing on
|
||
|
|
the input file(s) before assembling them. See <a href="Preprocessing.html#Preprocessing">Preprocessing</a>.

<blockquote>
|
||
|
|
<em>Warning:</em> if you use ‘<samp><span class="samp">-f</span></samp>’ when the files actually need to be
|
||
|
|
preprocessed (if they contain comments, for example), <samp><span class="command">as</span></samp> does
|
||
|
|
not work correctly.
