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