type ConTag = Int

Constructor Tag

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

type ConTagZ = Int

A *zero-indexed* constructor tag

fIRST_TAG :: ConTag

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

type Arity = Int

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 CoreArity

type RepArity = Int

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 () -> fib (x + y) has representation arity 2

type JoinArity = Int

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.

data OverlapMode

Constructors

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 {--} 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 {--} 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 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 InstEnv

The OneShotInfo type

data OneShotInfo

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.

Constructors

NoOneShotInfo

No information

OneShotLam

The lambda is applied at most once.
