* Refactor handling of global initializersBen Gamari2022-04-011-11/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | GHC uses global initializers for a number of things including cost-center registration, info-table provenance registration, and setup of foreign exports. Previously, the global initializer arrays which referenced these initializers would live in the object file of the C stub, which would then be merged into the main object file of the module. Unfortunately, this approach is no longer tenable with the move to Clang/LLVM on Windows (see #21019). Specifically, lld's PE backend does not support object merging (that is, the -r flag). Instead we are now rather packaging a module's object files into a static library. However, this is problematic in the case of initializers as there are no references to the C stub object in the archive, meaning that the linker may drop the object from the final link. This patch refactors our handling of global initializers to instead place initializer arrays within the object file of the module to which they belong. We do this by introducing a Cmm data declaration containing the initializer array in the module's Cmm stream. While the initializer functions themselves remain in separate C stub objects, the reference from the module's object ensures that they are not dropped from the final link. In service of #21068.
* Modularize Tidy (#17957)Sylvain Henry2022-03-251-50/+31
| | | | | | | | - Factorize Tidy options into TidyOpts datatype. Initialize it in GHC.Driver.Config.Tidy - Same thing for StaticPtrOpts - Perform lookups of unpackCString[Utf8]# once in initStaticPtrOpts instead of for every use of mkStringExprWithFS

* Use GHC's State monad consistentlyBen Gamari2021-05-291-1/+1
| | | | | | | | | | | | | GHC's internal State monad benefits from oneShot annotations on its state, allowing for more aggressive eta expansion. We currently don't have monad transformers with the same optimisation, so we only change uses of the pure State monad here. See #19657 and 19380. Metric Decrease: hie002

| | | | | | | | | | | | | Related to a future change in Data.List, https://downloads.haskell.org/ghc/8.10.3/docs/html/users_guide/using-warnings.html?highlight=wcompat#ghc-flag--Wcompat-unqualified-imports Companion pull&merge requests: - https://github.com/judah/haskeline/pull/153 - https://github.com/haskell/containers/pull/762 - https://gitlab.haskell.org/ghc/packages/hpc/-/merge_requests/9 After these the actual change in Data.List should be easy to do.
* Linker: reorganize linker related codeSylvain Henry2020-11-031-1/+2
| | | | | | | Move linker related code into GHC.Linker. Previously it was scattered into GHC.Unit.State, GHC.Driver.Pipeline, GHC.Runtime.Linker, etc. Add documentation in GHC.Linker
* Split GHC.Driver.TypesSylvain Henry2020-10-291-7/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Cache HomeUnit in HscEnv (#17957)Sylvain Henry2020-10-091-2/+2
| | | | | Instead of recreating the HomeUnit from the DynFlags every time we need it, we store it in the HscEnv.
* Introduce OutputablePSylvain Henry2020-09-171-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | Some types need a Platform value to be pretty-printed: CLabel, Cmm types, instructions, etc. Before this patch they had an Outputable instance and the Platform value was obtained via sdocWithDynFlags. It meant that the *renderer* of the SDoc was responsible of passing the appropriate Platform value (e.g. via the DynFlags given to showSDoc). It put the burden of passing the Platform value on the renderer while the generator of the SDoc knows the Platform it is generating the SDoc for and there is no point passing a different Platform at rendering time. With this patch, we introduce a new OutputableP class: class OutputableP a where pdoc :: Platform -> a -> SDoc With this class we still have some polymorphism as we have with `ppr` (i.e. we can use `pdoc` on a variety of types instead of having a dedicated `pprXXX` function for each XXX type). One step closer removing `sdocWithDynFlags` (#10143) and supporting several platforms (#14335).
* DynFlags: disentangle OutputableSylvain Henry2020-08-121-0/+1
| | | | | | | | | - put panic related functions into GHC.Utils.Panic - put trace related functions using DynFlags in GHC.Driver.Ppr One step closer making Outputable fully independent of DynFlags. Bump haddock submodule
* Clean up haddock hyperlinks of GHC.* (part2)Takenobu Tani2020-06-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | This updates haddock comments only. This patch focuses to update for hyperlinks in GHC API's haddock comments, because broken links especially discourage newcomers. This includes the following hierarchies: - GHC.Iface.* - GHC.Llvm.* - GHC.Rename.* - GHC.Tc.* - GHC.HsToCore.* - GHC.StgToCmm.* - GHC.CmmToAsm.* - GHC.Runtime.* - GHC.Unit.* - GHC.Utils.* - GHC.SysTools.*
* 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 Henry2020-04-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
