The <code>absolute-literals</code> and <code>no-absolute-literals</code>
directives control the absolute vs. PC-relative mode for <code>L32R</code>
instructions. These are relevant only for Xtensa configurations that
include the absolute addressing option for <code>L32R</code> instructions.
<pre class="smallexample"> .begin [no-]absolute-literals
.end [no-]absolute-literals
</pre>
<p>These directives do not change the <code>L32R</code> mode—they only cause
the assembler to emit the appropriate kind of relocation for <code>L32R</code>
instructions and to place the literal values in the appropriate section.
To change the <code>L32R</code> mode, the program must write the
<code>LITBASE</code> special register. It is the programmer's responsibility
to keep track of the mode and indicate to the assembler which mode is
used in each region of code.
<p>If the Xtensa configuration includes the absolute <code>L32R</code> addressing
option, the default is to assume absolute <code>L32R</code> addressing unless
the <span class="samp">--no-absolute-literals</span> command-line option is specified.
Otherwise, the default is to assume PC-relative <code>L32R</code> addressing.
The <code>absolute-literals</code> directive can then be used to override
the default determined by the command-line options.
