coreToDef :: Reftable r => LocSymbol -> Var -> CoreExpr -> LogicM [Def (Located (RRType r)) DataCon] #

coreToFun :: LocSymbol -> Var -> CoreExpr -> LogicM ([Var], Either Expr Expr) #

coreToLogic :: CoreExpr -> LogicM Expr #

mkLit :: Literal -> Maybe Expr #

mkI :: Integer -> Maybe Expr #

runToLogic :: TCEmb TyCon -> LogicMap -> DataConMap -> (String -> Error) -> LogicM t -> Either Error t #

runToLogicWithBoolBinds :: [Var] -> TCEmb TyCon -> LogicMap -> DataConMap -> (String -> Error) -> LogicM t -> Either Error t #

logicType :: Reftable r => Type -> RRType r #

inlineSpecType :: Var -> SpecType #

NOTE:inlineSpecType type: the refinement depends on whether the result type is a Bool or not: CASE1: measure flogic :: X -> Bool = fhaskell :: x:X -> {v:Bool | v = (flogic x)} CASE2: measure flogic :: X -> Y = fhaskell :: x:X -> {v:Y | v = (flogic x)}

measureSpecType :: Var -> SpecType #

Refine types of measures: keep going until you find the last data con! this code is a hack! we refine the last data constructor, it got complicated to support both 1. multi parameter measures (see testsposHasElem.hs) 2. measures returning functions (fromReader :: Reader r a -> (r -> a) ) TODO: SIMPLIFY by dropping support for multi parameter measures

weakenResult :: Var -> SpecType -> SpecType #

'weakenResult foo t' drops the singleton constraint `v = foo x y` that is added, e.g. for measures in /strengthenResult'. This should only be used _when_ checking the body of foo where the output, is, by definition, equal to the singleton.
