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