Comment (by simonmar):

 Replying to [comment:38 awson]:

 > Edit:
 > Perhaps, reusing {{{SymbolExtra *symbol_extras}}} pointer in
 {{{ObjectCode}}} structure is not such a good idea, because in current
 code {{{lookupSymbol}}} is used in haskell object-linking code and calls
 {{{lookupSymbolInDLLs}}} directly. Thus we probably should make a
 trampoline for every "far" symbol, imported from DLL, as is now in my
 patch.

 I don't understand this, could you explain more?  Surely it should be fine
 to return a 64-bit pointer from `lookupSymbol`?
