<p><a name="index-SH64-registers-1610"></a><a name="index-registers_002c-SH64-1611"></a>You can use the predefined symbols &lsquo;<samp><span class="samp">r0</span></samp>&rsquo; through &lsquo;<samp><span class="samp">r63</span></samp>&rsquo; to refer
to the SH64 general registers, &lsquo;<samp><span class="samp">cr0</span></samp>&rsquo; through <code>cr63</code> for
control registers, &lsquo;<samp><span class="samp">tr0</span></samp>&rsquo; through &lsquo;<samp><span class="samp">tr7</span></samp>&rsquo; for target address
registers, &lsquo;<samp><span class="samp">fr0</span></samp>&rsquo; through &lsquo;<samp><span class="samp">fr63</span></samp>&rsquo; for single-precision floating
point registers, &lsquo;<samp><span class="samp">dr0</span></samp>&rsquo; through &lsquo;<samp><span class="samp">dr62</span></samp>&rsquo; (even numbered registers
only) for double-precision floating point registers, &lsquo;<samp><span class="samp">fv0</span></samp>&rsquo; through
&lsquo;<samp><span class="samp">fv60</span></samp>&rsquo; (multiples of four only) for single-precision floating point
vectors, &lsquo;<samp><span class="samp">fp0</span></samp>&rsquo; through &lsquo;<samp><span class="samp">fp62</span></samp>&rsquo; (even numbered registers only)
for single-precision floating point pairs, &lsquo;<samp><span class="samp">mtrx0</span></samp>&rsquo; through
&lsquo;<samp><span class="samp">mtrx48</span></samp>&rsquo; (multiples of 16 only) for 4x4 matrices of
single-precision floating point registers, &lsquo;<samp><span class="samp">pc</span></samp>&rsquo; for the program
counter, and &lsquo;<samp><span class="samp">fpscr</span></samp>&rsquo; for the floating point status and control
register.

   <p>You can also refer to the control registers by the mnemonics &lsquo;<samp><span class="samp">sr</span></samp>&rsquo;,
