[Yhc] Some suggested changes to Yhc.Core

[Thomas Shackell]

Hi All,

I've been looking at compiling from Yhc.Core to Yhc bytecode (instead of 
from PosLambda) however there are one or two changes that I would need 
to make to Core to do this. All the changes (so-far) are limited to 
CorePrim, which would be changed to:

data CoreFunc
   = CoreFunc ...
   | CorePrim {
     coreFuncName :: CoreFuncName,     --^ name of the function in
                                       -- haskell
     corePrimArity :: Int,	      --^ arity of the function
     corePrimExternal :: Maybe String, --^ name of function in C (or 

                                       -- Nothing for same as haskell)
     corePrimConv :: String,	      --^ calling convention used
     corePrimImport :: Bool,	      --^ true for an import, false for
                                       -- an export
   }

i.e. this would add 3 constructors to the CorePrim data type. This would 
obviously break things for anyone who used a complete pattern match but 
if you only use the selectors it would continue to work fine.

Does anyone have any objections (or suggestions for additional ideas) to 
these changes?

Cheers

Tom
