8.4.2.4 Register Names
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.
