data IfaceTyCon Source #

Constructors

IfaceTyCon
Fields ifaceTyConName :: IfExtName ifaceTyConInfo :: !IfaceTyConInfo We add a bang to this field as heap analysis showed that this constructor retains a thunk to a value that is usually shared. See !12200 for how this bang saved ~10% residency when loading `mi_extra_decls` on the agda code base. See Note [Sharing IfaceTyConInfo] for why sharing is so important for `IfaceTyConInfo`.

mkIfaceTyConInfo :: PromotionFlag -> IfaceTyConSort -> IfaceTyConInfo Source #

This smart constructor allows sharing of the two most common cases. See Note [Sharing IfaceTyConInfo]

data IfaceTyConSort Source #

The various types of TyCons which have special, built-in syntax.

Constructors

IfaceNormalTyCon	a regular tycon
IfaceTupleTyCon !Arity !TupleSort	a tuple, e.g. `(a, b, c)` or `(#a, b, c#)`. The arity is the tuple width, not the tycon arity (which is twice the width in the case of unboxed tuples).
IfaceSumTyCon !Arity	an unboxed sum, e.g. `(# a \| b \| c #)`
IfaceEqualityTyCon	A heterogeneous equality TyCon (i.e. eqPrimTyCon, eqReprPrimTyCon, heqTyCon) that is actually being applied to two types of the same kind. This affects pretty-printing only: see Note [Equality predicates in IfaceType]

data FunTyFlag Source #

The non-dependent version of ForAllTyFlag. See Note [FunTyFlag] Appears here partly so that it's together with its friends ForAllTyFlag and ForallVisFlag, but also because it is used in IfaceType, rather early in the compilation chain

data ShowForAllFlag Source #

Show forall flag

Unconditionally show the forall quantifier with (ShowForAllMust) or when (ShowForAllWhen) the names used are free in the binder or when compiling with -fprint-explicit-foralls.

data ShowHowMuch Source #

Constructors

ShowHeader AltPpr	Header information only, not rhs
ShowSome (Maybe (OccName -> Bool)) AltPpr	Show the declaration and its RHS. The `Maybe` predicate allows filtering of the sub-components which should be printing; any sub-components filtered out will be elided with `...`.
ShowIface	Everything including GHC-internal information (used in --show-iface)

mkIfaceForAllTvBndr :: ForAllTyFlag -> IfaceTvBndr -> IfaceForAllBndr Source #

Make an IfaceForAllBndr from an IfaceTvBndr.

mkIfaceTyConKind :: [IfaceTyConBinder] -> IfaceKind -> IfaceKind Source #

Build the tyConKind from the binders and the result kind. Keep in sync with mkTyConKind in GHC.Core.TyCon.

ifaceForAllSpecToBndr :: IfaceForAllSpecBndr -> IfaceForAllBndr Source #

ifForAllBndrVar :: IfaceForAllBndr -> IfaceBndr Source #

Extract an IfaceBndr from an IfaceForAllBndr.

ifForAllBndrName :: IfaceForAllBndr -> IfLclName Source #

Extract the variable name from an IfaceForAllBndr.

ifaceBndrName :: IfaceBndr -> IfLclName Source #

ifTyConBinderVar :: IfaceTyConBinder -> IfaceBndr Source #

Extract an IfaceBndr from an IfaceTyConBinder.

Extract the variable name from an IfaceTyConBinder.

putIfaceType :: WriteBinHandle -> IfaceType -> IO () Source #

Serialises an IfaceType to the given WriteBinHandle.

Serialising inner IfaceType's uses the put of IfaceType which may be using a deduplication table. See Note [Deduplication during iface binary serialisation].

getIfaceType :: HasCallStack => ReadBinHandle -> IO IfaceType Source #

Deserialises an IfaceType from the given ReadBinHandle.

Reading inner IfaceType's uses the get of IfaceType which may be using a deduplication table. See Note [Deduplication during iface binary serialisation].

ifaceTypeSharedByte :: Word8 Source #

This is the byte tag we expect to read when the next value is not an IfaceType value, but an offset into a lookup table. See Note [Deduplication during iface binary serialisation].

Must not overlap with any byte tag in getIfaceType.

isIfaceLiftedTypeKind :: IfaceKind -> Bool Source #

Returns true for Type or (TYPE LiftedRep)

Prints a context or () if empty You give it the context precedence

pprIfaceContextArr :: [IfacePredType] -> SDoc Source #

Prints "(C a, D b) =>", including the arrow. Used when we want to print a context in a type, so we use funPrec to decide whether to parenthesise a singleton predicate; e.g. Num a => a -> a
