##### 9.40.2.2 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`’.
