Hi, An alpha build of ghc 6.4 quickly fails because of the #if alpha_TARGET_ARCH import PrimRep ( getPrimRepSize, isFloatingRep ) import Type ( typePrimRep ) #endif in ghc/compiler/typecheck/TcForeign.lhs which no longer exist. Fortunately, the imported functions aren't used either. Unfortunately, the build then fails when it comes to try to compile this same file as the typeMachRepRep function, used in this piece of code: \begin{code} #include "nativeGen/NCG.h" #if alpha_TARGET_ARCH checkFEDArgs arg_tys = check (integral_args <= 32) err where integral_args = sum [ machRepByteWidth rep | (rep,hint) <- map typeMachRepRep arg_tys, hint /= FloatHint ] err = ptext SLIT("On Alpha, I can only handle 4 non-floating-point arguments to foreign export dynamic") #else checkFEDArgs arg_tys = returnM () #endif \end{code} doesn't exist. Is this fixable? Thanks Ian
