simpleCase :: Bool -> SC -> Bool -> Phase -> FC -> [Int] -> [Type] -> [([Name], Term, Term)] -> ErasureInfo -> TC CaseDef Source

small :: Name -> [Name] -> SC -> Bool Source

findCalls :: SC -> [Name] -> [(Name, [[Name]])] Source

Return all called functions, and which arguments are used in each argument position for the call, in order to help reduce compilation time, and trace all unused arguments
