You can use the predefined symbols `r0' through `r15' to refer to the D10V registers. You can also use `sp' as an alias for `r15'. The accumulators are `a0' and `a1'. There are special register-pair names that may optionally be used in opcodes that require even-numbered registers. Register names are not case sensitive.
