Certainly; there is no point twiddling thumbs.
As the external-cmm syntax isn't fully tied down, we'll have to
synchronise PprCmm.hs with the Cmm parser. What is the best way to do
this, so that we emerge with a well-defined external representation for
Cmm?
Also, while we're here, a couple of questions:
* So we want both an external Cmm representation, as well as a true C--
code generator? So PprCmm is the external-cmm printer, but we also
need a C-- generator?
* Is the Cmm -> C pass going to be an adaptation of absCSyn/PprAbsC.lhs?
Cheers,
Don
