data StaticPtrCheck #

Constructors

AllowAnywhere | Allow `makeStatic` to occur anywhere.
AllowAtTopLevel | Allow `makeStatic` calls at the top-level only.
RejectEverywhere | Reject any `makeStatic` occurrence.

#### Instances

Instances details

Eq StaticPtrCheck # |
Instance details Defined in GHC.Core.Lint Methods (==) :: StaticPtrCheck -> StaticPtrCheck -> Bool # (/=) :: StaticPtrCheck -> StaticPtrCheck -> Bool #

data LintConfig #

Constructors

LintConfig |
Fields l_diagOpts :: !DiagOpts Diagnostics opts l_platform :: !Platform Target platform l_flags :: !LintFlags Linting the result of this pass l_vars :: ![Var] `Id`s that should be treated as being in scope

type WarnsAndErrs = (Bag SDoc, Bag SDoc) #

lintCoreBindings' :: LintConfig -> CoreProgram -> WarnsAndErrs #

Type-check a `CoreProgram`. See Note [Core Lint guarantee].

lintUnfolding #

Arguments

:: Bool | True = is a compulsory unfolding
-> LintConfig |
-> SrcLoc |
-> CoreExpr |
-> Maybe (Bag SDoc) |

lintPassResult :: Logger -> LintPassResultConfig -> CoreProgram -> IO () #

lintExpr :: LintConfig -> CoreExpr -> Maybe (Bag SDoc) #

lintAnnots :: SDoc -> (ModGuts -> CoreM ModGuts) -> ModGuts -> CoreM ModGuts #

This checks whether a pass correctly looks through debug annotations (`SourceNote`). This works a bit different from other consistency checks: We check this by running the given task twice, noting all differences between the results.

lintAxioms #

Arguments

:: Logger |
-> LintConfig |
-> SDoc | The source of the linted axioms
-> [CoAxiom Branched] |
-> IO () |

## Debug output

data EndPassConfig #

Configuration for boilerplate operations at the end of a compilation pass producing Core.

Constructors

EndPassConfig |
Fields ep_dumpCoreSizes :: !Bool Whether core bindings should be dumped with the size of what they are binding (i.e. the size of the RHS of the binding). ep_lintPassResult :: !(Maybe LintPassResultConfig) Whether we should lint the result of this pass. ep_namePprCtx :: !NamePprCtx ep_dumpFlag :: !(Maybe DumpFlag) ep_prettyPass :: !SDoc ep_passDetails :: !SDoc

endPassIO :: Logger -> EndPassConfig -> CoreProgram -> [CoreRule] -> IO () #

displayLintResults #

Arguments

:: Logger |
-> Bool | If `True`, display linter warnings. If `False`, ignore linter warnings.
-> SDoc | The source of the linted program
-> SDoc | The linted program, pretty-printed
-> WarnsAndErrs |
-> IO () |

dumpPassResult :: Logger -> Bool -> NamePprCtx -> Maybe DumpFlag -> String -> SDoc -> CoreProgram -> [CoreRule] -> IO () #
