Hi
I'm hoping that by the end of this summer, nhc98 will be able to compile
the whole of ghc. :-) Also, and alternatively, the yhc chaps have
mooted the idea of moving from nhc98's front end to ghc's, which might
eventually give you a fully portable bytecode route to bootstrapping ghc
on new machines.
We half thought about that, but a more direct goal is to be able to
convert GHC Core to Yhc Core, then we can use either GHC's front end
(via system) or Yhc's (natively). This would mean that we would be
able to compile any library with GHC then use it with Yhc. This
project will take about three days, once GHC has a non-broken Core
library.
How do you plan to implement unboxed types? AFAIK, implementing unboxed types
requires a typed intermediate language. Maybe you could get away with boxing
all the unboxed types, but then Int would have an extra level of boxing.
And the other big problem with implementing GHC core is all the primitives...
Cheers,
Simon
