  66. <p>The <code>literal_prefix</code> directive allows you to override the default
  67. literal section names, which are derived from the names of the sections
  68. where the literals are defined.

  74. <p>For literals defined within the delimited region, the literal section
  75. names are derived from the <var>name</var> argument instead of the name of
  76. the current section. The rules used to derive the literal section names
  77. do not change. See <a href="Literal-Directive.html#Literal-Directive">literal</a>. If the <var>name</var>
  78. argument is omitted, the literal sections revert to the defaults. This
  79. directive has no effect when using the
  80. &lsquo;<samp>--text-section-literals</samp>&rsquo; option (see <a href="Xtensa-Options.html#Xtensa-Options">Command Line Options</a>).
