friends ------------------------------------------------------------------------- -- A bit of magic going on here: there's no need to store the OccName -- for a decl on the disk, since we can infer the namespace from the -- context; however it is useful to have the OccName in the IfaceDecl -- to avoid re-building it in various places. So we build the OccName -- when de-serialising. instance Binary IfaceDecl where put_ bh (IfaceId name ty idinfo) = do putByte bh 0 put_ bh (occNameFS name) put_ bh ty put_ bh idinfo put_ bh (IfaceForeign ae af) = error "Binary.put_(IfaceDecl): IfaceForeign" put_ bh (IfaceData a1 a2 a3 a4 a5 a6 a7 a8) = do putByte bh 2 put_ bh (occNameFS a1) put_ bh a2 put_ bh a3 put_ bh a4 put_ bh a5 put_ bh a6 put_ bh a7 put_ bh a8 put_ bh (IfaceSyn aq ar as at) = do putByte bh 3 put_ bh (occNameFS aq) put_ bh ar put_ bh as put_ bh at put_ bh (IfaceClass a1 a2 a3 a4 a5 a6 a7) = do putByte bh 4 put_ bh a1 put_ bh (occNameFS a2) put_ bh a3 put_ bh a4 put_ bh a5 put_ bh a6 put_ bh a7 get bh = do h <- getByte bh case h of 0 -> do name <- get bh ty <- get bh idinfo <- get bh occ <- return $! mkOccNameFS varName name return (IfaceId occ ty idinfo) 1 -> error "Binary.get(TyClDecl): ForeignType" 2 -> do a1 <- get bh a2 <- get bh a3 <- get bh a4 <- get bh a5 <- get bh a6 <- get bh a7 <- get bh a8 <- get bh occ <- return $! mkOccNameFS tcName a1 return (IfaceData occ a2 a3 a4 a5 a6 a7 a8) 3 -> do aq <- get bh ar <- get bh as <- get bh at <- get bh occ <- return $! mkOccNameFS tcName aq return (IfaceSyn occ ar as at) _ -> do a1 <- get bh a2 <- get bh a3 <- get bh a4 <- get bh a5 <- get bh a6 <- get bh a7 <- get bh occ <- return $! mkOccNameFS clsName a2 return (IfaceClass a1 occ a3 a4 a5 a6 a7) instance Binary IfaceInst where put_ bh (IfaceInst cls tys dfun flag orph) = do put_ bh cls put_ bh tys put_ bh dfun put_ bh flag put_ bh orph get bh = do cls <- get bh tys <- get bh dfun <- get bh flag <- get bh orph <- get bh return (IfaceInst cls tys dfun flag orph) instance Binary IfaceFamInst where put_ bh (IfaceFamInst fam tys tycon) = do put_ bh fam put_ bh tys put_ bh tycon get bh = do fam <- get bh tys <- get bh tycon <- get bh return (IfaceFamInst fam tys tycon) instance Binary OverlapFlag where put_ bh NoOverlap = putByte bh 0 put_ bh OverlapOk = putByte bh 1 put_ bh Incoherent = putByte bh 2 get bh = do h <- getByte bh case h of 0 -> return NoOverlap 1 -> return OverlapOk 2 -> return Incoherent instance Binary IfaceConDecls where put_ bh IfAbstractTyCon = putByte bh 0 put_ bh IfOpenDataTyCon = putByte bh 1 put_ bh IfOpenNewTyCon = putByte bh 2 put_ bh (IfDataTyCon cs) = do { putByte bh 3 ; put_ bh cs } put_ bh (IfNewTyCon c) = do { putByte bh 4 ; put_ bh c } get bh = do h <- getByte bh case h of 0 -> return IfAbstractTyCon 1 -> return IfOpenDataTyCon 2 -> return IfOpenNewTyCon 3 -> do cs <- get bh return (IfDataTyCon cs) _ -> do aa <- get bh return (IfNewTyCon aa) instance Binary IfaceConDecl where put_ bh (IfCon a1 a2 a3 a4 a5 a6 a7 a8 a9) = do put_ bh a1 put_ bh a2 put_ bh a3 put_ bh a4 put_ bh a5 put_ bh a6 put_ bh a7 put_ bh a8 put_ bh a9 get bh = do a1 <- get bh a2 <- get bh a3 <- get bh a4 <- get bh a5 <- get bh a6 <- get bh a7 <- get bh a8 <- get bh a9 <- get bh return (IfCon a1 a2 a3 a4 a5 a6 a7 a8 a9) instance Binary IfaceClassOp where put_ bh (IfaceClassOp n def ty) = do put_ bh (occNameFS n) put_ bh def put_ bh ty get bh = do n <- get bh def <- get bh ty <- get bh occ <- return $! mkOccNameFS varName n return (IfaceClassOp occ def ty) instance Binary IfaceRule where put_ bh (IfaceRule a1 a2 a3 a4 a5 a6 a7) = do put_ bh a1 put_ bh a2 put_ bh a3 put_ bh a4 put_ bh a5 put_ bh a6 put_ bh a7 get bh = do a1 <- get bh a2 <- get bh a3 <- get bh a4 <- get bh a5 <- get bh a6 <- get bh a7 <- get bh return (IfaceRule a1 a2 a3 a4 a5 a6 a7)
