data LeftOrRight Source #
Instances
pickLR :: LeftOrRight -> (a, a) -> a Source #
Constructor Tag
Type of the tags associated with each constructor possibility or superclass selector
Tags are allocated from here for real constructors or for superclass selectors
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
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
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.

NoOverlap SourceText | This instance must not overlap another |
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) |

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.

data IntegralLit Source #
Integral Literal
Used (instead of Integer) to represent negative zegative zero which is required for NegativeLiterals extension to correctly parse `-0::Double` as negative zero. See also #13211.
Instances
data FractionalLit Source #
Fractional Literal
Used (instead of Rational) to represent exactly the floating point literal that we encountered in the user's source program. This allows us to pretty-print exactly what the user wrote, which is important e.g. for floating point numbers that can't represented as Doubles (we used to via Double for pretty-printing). See also #2245.
