<h3 class="section">2.7 Include Local Symbols: <samp><span class="option">-L</span></samp></h3>
<p><a name="index-g_t_002dL-69"></a><a name="index-local-symbols_002c-retaining-in-output-70"></a>Symbols beginning with system-specific local label prefixes, typically
&lsquo;<samp><span class="samp">.L</span></samp>&rsquo; for ELF systems or &lsquo;<samp><span class="samp">L</span></samp>&rsquo; for traditional a.out systems, are
called <dfn>local symbols</dfn>. See <a href="Symbol-Names.html#Symbol-Names">Symbol Names</a>. Normally you do not see
such symbols when debugging, because they are intended for the use of
programs (like compilers) that compose assembler programs, not for your
notice. Normally both <samp><span class="command">as</span></samp> and <code>ld</code> discard
such symbols, so you do not normally debug with them.
<p>This option tells <samp><span class="command">as</span></samp> to retain those local symbols
in the object file. Usually if you do this you also tell the linker
<code>ld</code> to preserve those symbols.
