type ConTag = Int Source #

A *one-index* constructor tag

Type of the tags associated with each constructor possibility or superclass selector

type ConTagZ = Int Source #

A *zero-indexed* constructor tag

fIRST_TAG :: ConTag Source #

Tags are allocated from here for real constructors or for superclass selectors

type Arity = Int Source #

The number of value arguments that can be applied to a value before it does "real work". So: fib 100 has arity 0 x -> fib x has arity 1 See also Note [Definition of arity] in GHC.Core.Opt.Arity

type RepArity = Int Source #

Representation Arity

The number of represented arguments that can be applied to a value before it does "real work". So: fib 100 has representation arity 0 x -> fib x has representation arity 1 (# x, y #) -> fib (x + y) has representation arity 2

type JoinArity = Int Source #

The number of arguments that a join point takes. Unlike the arity of a function, this is a purely syntactic property and is fixed when the join point is created (or converted from a value). Both type and value arguments are counted.

type FullArgCount = Int Source #

FullArgCount is the number of type or value arguments in an application, or the number of type or value binders in a lambda. Note: it includes both type and value arguments!

NoOverlap SourceText	This instance must not overlap another `NoOverlap` instance. However, it may be overlapped by `Overlapping` instances, and it may overlap `Overlappable` instances.
Overlappable SourceText	Silently ignore this instance if you find a more specific one that matches the constraint you are trying to resolve Example: constraint (Foo [Int]) instance Foo [Int] instance {-# OVERLAPPABLE #-} Foo [a] Since the second instance has the Overlappable flag, the first instance will be chosen (otherwise its ambiguous which to choose)
Overlapping SourceText	Silently ignore any more general instances that may be used to solve the constraint. Example: constraint (Foo [Int]) instance {-# OVERLAPPING #-} Foo [Int] instance Foo [a] Since the first instance has the Overlapping flag, the second---more general---instance will be ignored (otherwise it is ambiguous which to choose)
Overlaps SourceText	Equivalent to having both `Overlapping` and `Overlappable` flags.
Incoherent SourceText	Behave like Overlappable and Overlapping, and in addition pick an arbitrary one if there are multiple matching candidates, and don't worry about later instantiation Example: constraint (Foo [b]) instance {-# INCOHERENT -} Foo [Int] instance Foo [a] Without the Incoherent flag, we'd complain that instantiating `b` would change which instance was chosen. See also Note [Incoherent instances] in GHC.Core.InstEnv
NonCanonical SourceText	Behave like Incoherent, but the instance choice is observable by the program behaviour. See Note [Coherence and specialisation: overview]. We don't have surface syntax for the distinction between Incoherent and NonCanonical instances; instead, the flag `-f{no-}specialise-incoherents` (on by default) controls whether `INCOHERENT` instances are regarded as Incoherent or NonCanonical.

The OneShotInfo type

data OneShotInfo Source #

If the Id is a lambda-bound variable then it may have lambda-bound variable info. Sometimes we know whether the lambda binding this variable is a "one-shot" lambda; that is, whether it is applied at most once.

This information may be useful in optimisation, as computations may safely be floated inside such a lambda without risk of duplicating work.

See also Note [OneShotInfo overview] above.

Constructors

NoOneShotInfo	No information
OneShotLam	The lambda is applied at most once.

data NonStandardDefaultingStrategy Source #

Specify whether to default type variables of kind RuntimeRepLevityMultiplicity.

Constructors

DefaultNonStandardTyVars

Default type variables of the given kinds:

default RuntimeRep variables to LiftedRep
default Levity variables to Lifted
default Multiplicity variables to Many

TryNotToDefaultNonStandardTyVars

Try not to default type variables of the kinds RuntimeRepLevityMultiplicity.

Note that these might get defaulted anyway, if they are kind variables and `-XNoPolyKinds` is enabled.

data DefaultingStrategy Source #

Specify whether to default kind variables, and type variables of kind RuntimeRepLevityMultiplicity.

Constructors

DefaultKindVars

Default kind variables:

default kind variables of kind Type to Type,
default RuntimeRepLevityMultiplicity kind variables to LiftedRepLiftedMany, respectively.

When this strategy is used, it means that we have determined that the variables we are considering defaulting are all kind variables.

Usually, we pass this option when -XNoPolyKinds is enabled.

NonStandardDefaulting NonStandardDefaultingStrategy

Default (or don't default) non-standard variables, of kinds RuntimeRep, Levity and Multiplicity.
