* Split GHC.Driver.TypesSylvain Henry2020-10-291-5/+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
* DynFlags: disentangle OutputableSylvain Henry2020-08-121-0/+4
| | | | | | | | | - 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
* Clarify leaf module names for new module hierarchyTakenobu Tani2020-06-101-1/+1
| | | | | | | | | | | | | | | | | | | | | This updates comments only. This patch replaces leaf module names according to new module hierarchy [1][2] as followings: * Expand leaf names to easily find the module path: for instance, `Id.hs` to `GHC.Types.Id`. * Modify leaf names according to new module hierarchy: for instance, `Convert.hs` to `GHC.ThToHs`. * Fix typo: for instance, `GHC.Core.TyCo.Rep.hs` to `GHC.Core.TyCo.Rep` See also !3375 [1]: https://gitlab.haskell.org/ghc/ghc/-/wikis/Make-GHC-codebase-more-modular [2]: https://gitlab.haskell.org/ghc/ghc/issues/13009
* Remove further dead code found by a simple Python script.Brian Foley2020-05-081-1/+1
| | | | | Avoid removing some functions that are part of an API even though they're not used in-tree at the moment.
* Refactor hole constraints.Richard Eisenberg2020-05-061-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, holes (both expression holes / out of scope variables and partial-type-signature wildcards) were emitted as *constraints* via the CHoleCan constructor. While this worked fine for error reporting, there was a fair amount of faff in keeping these constraints in line. In particular, and unlike other constraints, we could never change a CHoleCan to become CNonCanonical. In addition: * the "predicate" of a CHoleCan constraint was really the type of the hole, which is not a predicate at all * type-level holes (partial type signature wildcards) carried evidence, which was never used * tcNormalise (used in the pattern-match checker) had to create a hole constraint just to extract it again; it was quite messy The new approach is to record holes directly in WantedConstraints. It flows much more nicely now. Along the way, I did some cleaning up of commentary in GHC.Tc.Errors.Hole, which I had a hard time understanding. This was instigated by a future patch that will refactor the way predicates are handled. The fact that CHoleCan's "predicate" wasn't really a predicate is incompatible with that future patch. No test case, because this is meant to be purely internal. It turns out that this change improves the performance of the pattern-match checker, likely because fewer constraints are sloshing about in tcNormalise. I have not investigated deeply, but an improvement is not a surprise here: ------------------------- Metric Decrease: PmSeriesG -------------------------
