* Allow primops in a :print (and friends) command. Fix #19394Roland Senn2021-06-021-1/+6
| | | | | | | * For primops from `GHC.Prim` lookup the HValues in `GHC.PrimopWrappers`. * Add short error messages if a user tries to use a *Non-Id* value or a `pseudoop` in a `:print`, `:sprint` or `force`command. * Add additional test cases for `Magic Ids`.

* Replace CPP assertions with Haskell functionsSylvain Henry2021-05-121-3/+3
| | | | | | | | | | | | | | | There is no reason to use CPP. __LINE__ and __FILE__ macros are now better replaced with GHC's CallStack. As a bonus, assert error messages now contain more information (function name, column). Here is the mapping table (HasCallStack omitted): * ASSERT: assert :: Bool -> a -> a * MASSERT: massert :: Bool -> m () * ASSERTM: assertM :: m Bool -> m () * ASSERT2: assertPpr :: Bool -> SDoc -> a -> a * MASSERT2: massertPpr :: Bool -> SDoc -> m () * ASSERTM2: assertPprM :: m Bool -> SDoc -> m ()
* Move loader state into InterpSylvain Henry2021-03-231-53/+72
| | | | | | | | | | | | | | | | | | The loader state was stored into HscEnv. As we need to have two interpreters and one loader state per interpreter in #14335, it's natural to make the loader state a field of the Interp type. As a side effect, many functions now only require a Interp parameter instead of HscEnv. Sadly we can't fully free GHC.Linker.Loader of HscEnv yet because the loader is initialised lazily from the HscEnv the first time it is used. This is left as future work. HscEnv may not contain an Interp value (i.e. hsc_interp :: Maybe Interp). So a side effect of the previous side effect is that callers of the modified functions now have to provide an Interp. It is satisfying as it pushes upstream the handling of the case where HscEnv doesn't contain an Interpreter. It is better than raising a panic (less partial functions, "parse, don't validate", etc.).

* Split GHC.Driver.TypesSylvain Henry2020-10-291-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I was working on making DynFlags stateless (#17957), especially by storing loaded plugins into HscEnv instead of DynFlags. It turned out to be complicated because HscEnv is in GHC.Driver.Types but LoadedPlugin isn't: it is in GHC.Driver.Plugins which depends on GHC.Driver.Types. I didn't feel like introducing yet another hs-boot file to break the loop. Additionally I remember that while we introduced the module hierarchy (#13009) we talked about splitting GHC.Driver.Types because it contained various unrelated types and functions, but we never executed. I didn't feel like making GHC.Driver.Types bigger with more unrelated Plugins related types, so finally I bit the bullet and split GHC.Driver.Types. As a consequence this patch moves a lot of things. I've tried to put them into appropriate modules but nothing is set in stone. Several other things moved to avoid loops. * Removed Binary instances from GHC.Utils.Binary for random compiler things * Moved Typeable Binary instances into GHC.Utils.Binary.Typeable: they import a lot of things that users of GHC.Utils.Binary don't want to depend on. * put everything related to Units/Modules under GHC.Unit: GHC.Unit.Finder, GHC.Unit.Module.{ModGuts,ModIface,Deps,etc.} * Created several modules under GHC.Types: GHC.Types.Fixity, SourceText, etc. * Split GHC.Utils.Error (into GHC.Types.Error) * Finally removed GHC.Driver.Types Note that this patch doesn't put loaded plugins into HscEnv. It's left for another patch. Bump haddock submodule

* Enhance UnitId useSylvain Henry2020-06-131-1/+1
| | | | | | | | * use UnitId instead of String to identify wired-in units * use UnitId instead of Unit in the backend (Unit are only use by Backpack to produce type-checked interfaces, not real code) * rename lookup functions for consistency * documentation
* Eta expand un-saturated primopsBen Gamari2020-05-291-0/+1
| | | | | | | | | | | Now since we no longer try to predict CAFfyness we have no need for the solution to #16846. Eta expanding unsaturated primop applications is conceptually simpler, especially in the presence of levity polymorphism. This essentially reverts cac8dc9f51e31e4c0a6cd9bc302f7e1bc7c03beb, as suggested in #18079. Closes #18079.
* Unit: split and rename modulesSylvain Henry2020-04-301-1/+1
| | | | | | | Introduce GHC.Unit.* hierarchy for everything concerning units, packages and modules. Update Haddock submodule
* Refactoring unit management codeSylvain Henry2020-04-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Over the years the unit management code has been modified a lot to keep up with changes in Cabal (e.g. support for several library components in the same package), to integrate BackPack, etc. I found it very hard to understand as the terminology wasn't consistent, was referring to past concepts, etc. The terminology is now explained as clearly as I could in the Note "About Units" and the code is refactored to reflect it. ------------------- Many names were misleading: UnitId is not an Id but could be a virtual unit (an indefinite one instantiated on the fly), IndefUnitId constructor may contain a definite instantiated unit, etc. * Rename IndefUnitId into InstantiatedUnit * Rename IndefModule into InstantiatedModule * Rename UnitId type into Unit * Rename IndefiniteUnitId constructor into VirtUnit * Rename DefiniteUnitId constructor into RealUnit * Rename packageConfigId into mkUnit * Rename getPackageDetails into unsafeGetUnitInfo * Rename InstalledUnitId into UnitId Remove references to misleading ComponentId: a ComponentId is just an indefinite unit-id to be instantiated. * Rename ComponentId into IndefUnitId * Rename ComponentDetails into UnitPprInfo * Fix display of UnitPprInfo with empty version: this is now used for units dynamically generated by BackPack Generalize several types (Module, Unit, etc.) so that they can be used with different unit identifier types: UnitKey, UnitId, Unit, etc. * GenModule: Module, InstantiatedModule and InstalledModule are now instances of this type * Generalize DefUnitId, IndefUnitId, Unit, InstantiatedUnit, PackageDatabase Replace BackPack fake "hole" UnitId by a proper HoleUnit constructor. Add basic support for UnitKey. They should be used more in the future to avoid mixing them up with UnitId as we do now. Add many comments. Update Haddock submodule
