|
|
<p>Symbols beginning with system-specific local label prefixes, typically
|
|
‘<samp>.L</samp>’ for ELF systems or ‘<samp>L</samp>’ for traditional a.out systems, are
|
|
called <em>local symbols</em>. 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 <code>as</code> and <code>ld</code> discard
|
|
such symbols, so you do not normally debug with them.
|
|
</p>
|
|
<p>This option tells <code>as</code> 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.
