<p><a name="index-SH64-registers-1975"></a><a name="index-registers_002c-SH64-1976"></a>You can use the predefined symbols ‘<samp><span class="samp">r0</span></samp>’ through ‘<samp><span class="samp">r63</span></samp>’ to refer
to the SH64 general registers, ‘<samp><span class="samp">cr0</span></samp>’ through <code>cr63</code> for
control registers, ‘<samp><span class="samp">tr0</span></samp>’ through ‘<samp><span class="samp">tr7</span></samp>’ for target address
registers, ‘<samp><span class="samp">fr0</span></samp>’ through ‘<samp><span class="samp">fr63</span></samp>’ for single-precision floating
point registers, ‘<samp><span class="samp">dr0</span></samp>’ through ‘<samp><span class="samp">dr62</span></samp>’ (even numbered registers
only) for double-precision floating point registers, ‘<samp><span class="samp">fv0</span></samp>’ through
‘<samp><span class="samp">fv60</span></samp>’ (multiples of four only) for single-precision floating point
vectors, ‘<samp><span class="samp">fp0</span></samp>’ through ‘<samp><span class="samp">fp62</span></samp>’ (even numbered registers only)
for single-precision floating point pairs, ‘<samp><span class="samp">mtrx0</span></samp>’ through
‘<samp><span class="samp">mtrx48</span></samp>’ (multiples of 16 only) for 4x4 matrices of
single-precision floating point registers, ‘<samp><span class="samp">pc</span></samp>’ for the program
counter, and ‘<samp><span class="samp">fpscr</span></samp>’ for the floating point status and control
register.
<p>You can also refer to the control registers by the mnemonics ‘<samp><span class="samp">sr</span></samp>’,
‘<samp><span class="samp">ssr</span></samp>’, ‘<samp><span class="samp">pssr</span></samp>’, ‘<samp><span class="samp">intevt</span></samp>’, ‘<samp><span class="samp">expevt</span></samp>’, ‘<samp><span class="samp">pexpevt</span></samp>’,
‘<samp><span class="samp">tra</span></samp>’, ‘<samp><span class="samp">spc</span></samp>’, ‘<samp><span class="samp">pspc</span></samp>’, ‘<samp><span class="samp">resvec</span></samp>’, ‘<samp><span class="samp">vbr</span></samp>’,
‘<samp><span class="samp">tea</span></samp>’, ‘<samp><span class="samp">dcr</span></samp>’, ‘<samp><span class="samp">kcr0</span></samp>’, ‘<samp><span class="samp">kcr1</span></samp>’, ‘<samp><span class="samp">ctc</span></samp>’, and
