Description

Case trees.

After coverage checking, pattern matching is translated to case trees, i.e., a tree of successive case splits on one variable at a time.

data Case c Source #

Branches in a case tree.

Constructors

Branches

Fields

projPatterns :: Bool
We are constructing a record here (copatterns). conBranches lists projections.
conBranches :: Map QName (WithArity c)
Map from constructor (or projection) names to their arity and the case subtree. (Projections have arity 0.)
etaBranch :: Maybe (ConHead, WithArity c)
Eta-expand with the given (eta record) constructor. If this is present, there should not be any conBranches or litBranches.
litBranches :: Map Literal c
Map from literal to case subtree.
catchAllBranch :: Maybe c
(Possibly additional) catch-all clause.
fallThrough :: Maybe Bool
(if True) In case of non-canonical argument use catchAllBranch.
lazyMatch :: Bool
Lazy pattern match. Requires single (non-copattern) branch with no lit branches and no catch-all.

data CompiledClauses' a Source #

Case tree with bodies.

Constructors

Case (Arg Int) (Case (CompiledClauses' a))	`Case n bs` stands for a match on the `n`-th argument (counting from zero) with `bs` as the case branches. If the `n`-th argument is a projection, we have only `conBranches` with arity 0.
Done [Arg ArgName] a	`Done xs b` stands for the body `b` where the `xs` contains hiding and name suggestions for the free variables. This is needed to build lambdas on the right hand side for partial applications which can still reduce.
Fail [Arg ArgName]	Absurd case. Add the free variables here as well so we can build correct number of lambdas for strict backends. (#4280)
