Make validating with GhcProfiled=YES Just Work It now takes care of adding p to the GhcLibWays, rather than just complaining that it's missing.

10:40 PM Changeset in ghc [c4b2ac3]ghc-7.6th-new-7.6 by Ian Lynagh <ian@…>
Fix TcUnify.matchExpectedTyConApp so that it returns types of compatible kinds This fixes Trac #7368. The problem was that we were matching Bad w ~ f (Bad f) where (f :: * -> *). Thta leads to (w ~ Bad f), which is ill-kinded, but matchExpectedTyConApp was returning the (Bad f) as the argument type, and that was being used to instanatiate w in the data constructor type, which is very bad. The code also becomes simpler and easier to understand, which is an excellent thing.

In type or data instances, check that all variables are bound Trac #7536 points out that it's possible for the LHS to *look* as if it binds variables, but does not acutally do so type T a = Int type instance F (T a) = a This patch makes it an error.

Refactor the invariants for ClsInsts We now have the invariant for a ClsInst that the is_tvs field is always completely fresh type variables. See Note [Template tyvars are fresh] in InstEnv. (Previously we frehened them when extending the instance environment, but that seems messier because it was an invariant only when the ClsInst was in an InstEnv. Moreover, there was an invariant that thet tyvars of the DFunid in the ClsInst had to match, and I have removed that invariant altogether; there is no need for it.) Other changes I made at the same time: * Make is_tvs into a *list*, in the right order for the dfun type arguments. This removes the wierd need for the dfun to have the same tyvars as the ClsInst template, an invariant I have always hated. The cost is that we need to make it a VarSet when matching. We could cache an is_tv_set instead. * Add a cached is_cls field to the ClsInst, to save fishing the Class out of the DFun. (Renamed is_cls to is_cls_nm.) * Make tcSplitDFunTy return the dfun args, not just the *number* of dfun args * Make InstEnv.instanceHead return just the *head* of the instance declaration. Add instanceSig to return the whole thing.

Fix dictionaries for SingI. This adds the missing coercions in the constructed evidence for SingI. Previously we simply passed an integer or a string for the evidence, which was not quite correct and causes errors when the core lint is enabled. This patch corrects this by inserting the necessary coercions.
Note: See TracTimeline for information about the timeline view.
