  75. <p>Some symbols are defined by the assembler.  They&rsquo;re intended to

  76. be used in conditional assembly, for example:

  77. </p><div class="smallexample">

  78. <pre class="smallexample"> .if ..asm.arch.cris.v32

  79.  <var>code for CRIS v32</var>

  80.  .elseif ..asm.arch.cris.common_v10_v32

  81.  <var>code common to CRIS v32 and CRIS v10</var>

  82.  .elseif ..asm.arch.cris.v10 | ..asm.arch.cris.any_v0_v10

  83.  <var>code for v10</var>

  84.  .else

  85.  .error &quot;Code needs to be added here.&quot;

  86.  .endif

  87. </pre></div>

  88. 

  89. <p>These symbols are defined in the assembler, reflecting

  90. command-line options, either when specified or the default.

  91. They are always defined, to 0 or 1.

  92. </p><dl compact="compact">

  93. <dt><code>..asm.arch.cris.any_v0_v10</code></dt>

  94. <dd><p>This symbol is non-zero when <samp>--march=v0_v10</samp> is specified

  95. or the default.

  96. </p>

  97. </dd>

  98. <dt><code>..asm.arch.cris.common_v10_v32</code></dt>

  99. <dd><p>Set according to the option <samp>--march=common_v10_v32</samp>.

  100. </p>

  101. </dd>

  102. <dt><code>..asm.arch.cris.v10</code></dt>

  103. <dd><p>Reflects the option <samp>--march=v10</samp>.

  106. <dt><code>..asm.arch.cris.v32</code></dt>

  107. <dd><p>Corresponds to <samp>--march=v10</samp>.

  108. </p></dd>

  111. <p>Speaking of symbols, when a symbol is used in code, it can have

  112. a suffix modifying its value for use in position-independent

  113. code. See <a href="CRIS_002dPic.html#CRIS_002dPic">CRIS-Pic</a>.
