##### 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`.
