##### 9.29.2.2 Register Names

You can use the predefined symbols ``r0`' through ``r63`' to refer to the SH64 general registers, ``cr0`' through `cr63` for control registers, ``tr0`' through ``tr7`' for target address registers, ``fr0`' through ``fr63`' for single-precision floating point registers, ``dr0`' through ``dr62`' (even numbered registers only) for double-precision floating point registers, ``fv0`' through ``fv60`' (multiples of four only) for single-precision floating point vectors, ``fp0`' through ``fp62`' (even numbered registers only) for single-precision floating point pairs, ``mtrx0`' through ``mtrx48`' (multiples of 16 only) for 4x4 matrices of single-precision floating point registers, ``pc`' for the program counter, and ``fpscr`' for the floating point status and control register.

You can also refer to the control registers by the mnemonics ``sr`', ``ssr`', ``pssr`', ``intevt`', ``expevt`', ``pexpevt`', ``tra`', ``spc`', ``pspc`', ``resvec`', ``vbr`', ``tea`', ``dcr`', ``kcr0`', ``kcr1`', ``ctc`', and ``usr`'.
