Free variables of expressions and binding groups
exprFreeVars :: CoreExpr -> VarSet Source #
Find all locally-defined free Ids or type variables in an expression returning a non-deterministic set.
exprFreeVarsDSet :: CoreExpr -> DVarSet Source #
Find all locally-defined free Ids or type variables in an expression returning a deterministic set.
exprFreeIds :: CoreExpr -> IdSet Source #
Find all locally-defined free Ids in an expression
exprsFreeVars :: [CoreExpr] -> VarSet Source #
Find all locally-defined free Ids or type variables in several expressions returning a non-deterministic set.

Selective free variables of expressions
type InterestingVarFun = Var -> Bool Source #
Predicate on possible free variables: returns True iff the variable is
interesting
Arguments
| :: InterestingVarFun | Says which |
| -> CoreExpr | |
| -> VarSet |

idRuleAndUnfoldingVars :: Id -> VarSet Source #
idFreeVarsAcc :: Id -> FV Source #
idRuleVars :: Id -> VarSet Source #
idRuleRhsVars :: (Activation -> Bool) -> Id -> VarSet Source #
ruleRhsFreeVars :: CoreRule -> VarSet Source #
Those variables free in the right hand side of a rule returned as a non-deterministic set
ruleFreeVars :: CoreRule -> VarSet Source #
Those variables free in the both the left right hand sides of a rule returned as a non-deterministic set
rulesFreeVars :: [CoreRule] -> VarSet Source #
Those variables free in the right hand side of several rules
rulesFreeVarsDSet :: [CoreRule] -> DVarSet Source #
Those variables free in the both the left right hand sides of rules returned as a deterministic set
ruleLhsFreeIds :: CoreRule -> VarSet Source #
This finds all locally-defined free Ids on the left hand side of a rule
vectsFreeVars :: [CoreVect] -> VarSet Source #
Free variables of a vectorisation declaration
Orphan names
orphNamesOfType :: Type -> NameSet Source #
orphNamesOfCo :: Coercion -> NameSet Source #
orphNamesOfAxiom :: CoAxiom br -> NameSet Source #
orphNamesOfTypes :: [Type] -> NameSet Source #
orphNamesOfCoCon :: CoAxiom br -> NameSet Source #
exprsOrphNames :: [CoreExpr] -> NameSet Source #
Finds the free external names of several expressions: see exprOrphNames for details
orphNamesOfFamInst :: FamInst -> NameSet Source #
orphNamesOfAxiom collects the names of the concrete types and type constructors that make up the LHS of a type family instance, including the family name itself.
For instance, given `type family Foo a b`: `type instance Foo (F (G (H a))) b = ...` would yield [Foo,F,G,H]
Used in the implementation of ":info" in GHCi.
Core syntax tree annotation with free variables
type CoreExprWithFVs = AnnExpr Id FVAnn Source #

freeVarsOf :: CoreExprWithFVs -> DIdSet Source #
Inverse function to freeVars
freeVarsOfType :: CoreExprWithFVs -> DTyCoVarSet Source #
Extract the vars free in an annotated expression's type
