Documentation
idPrimRep :: Id -> PrimRep Source #
Assumes that there is precisely one PrimRep of the type. This assumption
holds after unarise.
See Note [Post-unarisation invariants]
isGcPtrRep :: PrimRep -> Bool Source #
addIdReps :: [NonVoid Id] -> [NonVoid (PrimRep, Id)] Source #
Assumes that Ids have one PrimRep, which holds after unarisation. See Note [Post-unarisation invariants]
addArgReps :: [NonVoid StgArg] -> [NonVoid (PrimRep, StgArg)] Source #
Assumes that arguments have one PrimRep, which holds after unarisation. See Note [Post-unarisation invariants]
argPrimRep :: StgArg -> PrimRep Source #
Assumes that the argument has one PrimRep, which holds after unarisation. See Note [Post-unarisation invariants]
Constructors
| NonVoid a |
fromNonVoid :: NonVoid a -> a Source #
assertNonVoidIds :: [Id] -> [NonVoid Id] Source #
Used in places where some invariant ensures that all these Ids are non-void; e.g. constructor field binders in case expressions. See Note [Post-unarisation invariants] in GHC.Stg.Unarise.
assertNonVoidStgArgs :: [StgArg] -> [NonVoid StgArg] Source #
Used in places where some invariant ensures that all these arguments are non-void; e.g. constructor arguments. See Note [Post-unarisation invariants] in GHC.Stg.Unarise.
LambdaFormInfo
data LambdaFormInfo Source #
Information about an identifier, from the code generator's point of view. Every identifier is bound to a LambdaFormInfo in the environment, which gives the code generator enough info to be able to tail call or return that identifier.

StandardFormInfo tells whether this thunk has one of a small number of standard forms
