I'm frankly happy with it specifying the semantics by reference to the
ARM docs -- that way we can easily share existing code without concern
about subtle semantic differences.

The only thing that would be useful is to clarify the low-level ABI
details about argument passing, but given that the ARM semihosting spec
passes arguments in the standard registers, extrapolating that to RISC-V
is not exactly difficult.

I can certainly ask to have the argument passing details clarified; I
doubt that group would be interested in adopting the whole semihosting
spec and publishing it separately.
