<h5 class="subsection">Register Names</h5>



   <p>You can use the predefined symbols <code>r0</code> through <code>r63</code> to refer

to the SH64 general registers, <code>cr0</code> through <code>cr63</code> for

control registers, <code>tr0</code> through <code>tr7</code> for target address

registers, <code>fr0</code> through <code>fr63</code> for single-precision floating

point registers, <code>dr0</code> through <code>dr62</code> (even numbered registers

only) for double-precision floating point registers, <code>fv0</code> through

<code>fv60</code> (multiples of four only) for single-precision floating point

vectors, <code>fp0</code> through <code>fp62</code> (even numbered registers only)

for single-precision floating point pairs, <code>mtrx0</code> through

<code>mtrx48</code> (multiples of 16 only) for 4x4 matrices of

single-precision floating point registers, <code>pc</code> for the program

counter, and <code>fpscr</code> for the floating point status and control

register.



   <p>You can also refer to the control registers by the mnemonics <code>sr</code>,

<code>ssr</code>, <code>pssr</code>, <code>intevt</code>, <code>expevt</code>, <code>pexpevt</code>,

<code>tra</code>, <code>spc</code>, <code>pspc</code>, <code>resvec</code>, <code>vbr</code>,

<code>tea</code>, <code>dcr</code>, <code>kcr0</code>, <code>kcr1</code>, <code>ctc</code>, and

<code>usr</code>.
