  67. <p>Symbols beginning with system-specific local label prefixes, typically
  68. &lsquo;<samp>.L</samp>&rsquo; for ELF systems or &lsquo;<samp>L</samp>&rsquo; for traditional a.out systems, are
  69. called <em>local symbols</em>. See <a href="Symbol-Names.html#Symbol-Names">Symbol Names</a>. Normally you do not see
  70. such symbols when debugging, because they are intended for the use of
  71. programs (like compilers) that compose assembler programs, not for your
  72. notice. Normally both <code>as</code> and <code>ld</code> discard
  73. such symbols, so you do not normally debug with them.
  74. </p>
  75. <p>This option tells <code>as</code> to retain those local symbols
  76. in the object file. Usually if you do this you also tell the linker
  77. <code>ld</code> to preserve those symbols.
