Fix parent position in RnNames.nubAvails - `RnNames.nubAvails', which amalgamates AvailInfo items that belong to the same parent, needs to be careful that the parent name occurs first if it is in the list of subnames at all. (Otherwise, we can get funny export items in ifaces.) - I discovered this while debugging family import/exports, but I am pretty sure the bug would also have shown up without using families under the right circumstances.

Fix processing of imports involving ATs with the new name parent code Associated types in import lists require special care and the new name parent code broke that. What's the problem? in the presence of ATs the name parent relation can have a depth of two (not just one as in H98). Here is an example: class GMapKey a where data GMap a :: * -> * instance GMapKey Int where data GMap Int v = GMapInt ... The data constructor GMapInt's parent is GMap whose parent in turn is the class GMapKey; ie, GMapKey is GMapInt's grand parent. In H98, data types have no parents (which is in some places in the code represented by making them their own parent). I fixed this by extending the information in filterImport's occ_env and taking the case of associated types explicitly in consideration when processing the various forms of IE items.

Fix family instance bug due to the name parent elimination - Its important that `isImplicitTyCon' considers (a) associated families to be implicit, but (b) considers family instances *not* to be implicit (for the same reasons that a dfun is not implicit).

Add the primitive type Any, and use it for Dynamics GHC's code generator can only enter a closure if it's guaranteed not to be a function. In the Dynamic module, we were using the type (forall a.a) as the type to which the dynamic type was unsafely cast: type Obj = forall a.a Gut alas this polytype was sometimes instantiated to (), something like this (it only bit when profiling was enabled) let y::() = dyn () in (y `cast` ..) p q As a result, an ASSERT in ClosureInfo fired (hooray). I've tided this up by making a new, primitive, lifted type Any, and arranging that Dynamic uses Any, thus: type Obj = ANy While I was at it, I also arranged that when the type checker instantiates un-constrained type variables, it now instantiates them to Any, not () e.g. length Any [] [There remains a Horrible Hack when we want Any-like things at arbitrary kinds. This essentially never happens, but see comments with TysPrim.mkAnyPrimTyCon.] Anyway, this fixes Trac #905

Add comment about arity I'm not sure what the significance of the "arity" of a primtive TyCon is. They aren't necessarily saturated, so it's not that. I rather think that arity is only relevant for SynTyCon AlgTyCon CoercionTyCon This comment (and commit message) is just an aide memoire.

Add assertion checks for mkCoVar/mkTyVar A type variable has a flag saying whether it is a *type* variable or a *coercion* variable. This patch adds assertions to check the flag. And it adds fixes to places which were Wrong (and hence fired the assertion)! Also removed isCoVar from Coercion, since it's done by Var.isCoVar.

More refactoring in RnNames I rather self-indulgently spent a chunk of yesterday working on refactoring RnNames further. The result is significantly simpler: * A GlobalRdrElt gets an extra field, gre_par, which records the parent (if any) of the name * ImportAvails has two fields deleted: imp_env and imp_parent. The information provided by these fields was only used when processing the export list; and the same information is now readily generated from the GlobalRdrElts in the GlobalRdrEnv I also did some tidying up; notably moving AvailEnv stuff from TcRnTypes to RnNames. The result is tha the compiler is some 130 lines shorter than before

Keep track of family instance modules - Now each modules carries (1) a flag saying whether it contains family instance declarations and (2) a list of all modules further down in the import tree that contain family instance declarations. (The information is split into these two parts for the exact same reasons why the info about orphan modules is split, too.) - This is the first step to *optimised* overlap checking of family instances coming from imported modules. *** WARNING: This patch changes the interface file format! *** *** Recompile libraries and stage2 from scratch! ***

Fix trac #921: generate *q instructions for int-float conversions We need to generate, e.g., cvtsi2sdq rather than cvtsi2sd on amd64 in order to have int-float conversions work correctly for values not correctly representable in 32 bits.

Interface file optimisation and removal of nameParent This large commit combines several interrelated changes: - IfaceSyn now contains actual Names rather than the special IfaceExtName type. The binary interface file contains a symbol table of Names, where each entry is a (package, ModuleName, OccName) triple. Names in the IfaceSyn point to entries in the symbol table. This reduces the size of interface files, which should hopefully improve performance (not measured yet). The toIfaceXXX functions now do not need to pass around a function from Name -> IfaceExtName, which makes that code simpler. - Names now do not point directly to their parents, and the nameParent operation has gone away. It turned out to be hard to keep this information consistent in practice, and the parent info was only valid in some Names. Instead we made the following changes: * ImportAvails contains a new field imp_parent :: NameEnv AvailInfo which gives the family info for any Name in scope, and is used by the renamer when renaming export lists, amongst other things. This info is thrown away after renaming. * The mi_ver_fn field of ModIface now maps to (OccName,Version) instead of just Version, where the OccName is the parent name. This mapping is used when constructing the usage info for dependent modules. There may be entries in mi_ver_fn for things that are not in scope, whereas imp_parent only deals with in-scope things. * The md_exports field of ModDetails now contains [AvailInfo] rather than NameSet. This gives us family info for the exported names of a module. Also: - ifaceDeclSubBinders moved to IfaceSyn (seems like the right place for it). - heavily refactored renaming of import/export lists. - Unfortunately external core is now broken, as it relied on IfaceSyn. It requires some attention.

Module header tidyup, phase 1 This patch is a start on removing import lists and generally tidying up the top of each module. In addition to removing import lists: - Change DATA.IOREF -> Data.IORef etc. - Change List -> Data.List etc. - Remove $Id$ - Update copyrights - Re-order imports to put non-GHC imports last - Remove some unused and duplicate imports

Do not filter the type envt after each GHCi stmt Fixes Trac #925 A new comment in TcRnDriver in tcRnStmt reads thus: At one stage I removed any shadowed bindings from the type_env; they are inaccessible but might, I suppose, cause a space leak if we leave them there. However, with Template Haskell they aren't necessarily inaccessible. Consider this GHCi session Prelude> let f n = n * 2 :: Int Prelude> fName <- runQ [| f |] Prelude> $(return $ AppE fName (LitE (IntegerL 7))) 14 Prelude> let f n = n * 3 :: Int Prelude> $(return $ AppE fName (LitE (IntegerL 7))) In the last line we use 'fName', which resolves to the *first* 'f' in scope. If we delete it from the type env, GHCi crashes because it doesn't expect that.

Rough matches for family instances - Class and type family instances just got a lot more similar. - FamInst, like Instance, now has a rough match signature. The idea is the same: if the rough match doesn't match, there is no need to pull in the while tycon describing the instance (from a lazily read iface). - IfaceFamInst changes in a similar way and the list of all IFaceFamInsts is now written into the binary iface (as for class instances), as deriving it from the tycon (as before) would render the whole rough matching useless. - As a result of this, the plumbing of class instances and type instances through the various environments, ModIface, ModGuts, and ModDetails is now almost the same. (The remaining difference are mostly because the dfun of a class instance is an Id, but type instance refer to a TyCon, not an Id.) *** WARNING: The interface file format changed! *** *** Rebuild from scratch. ***
