Make the treatment of addAltUnfoldings handle casts This minor refactoring re-attaches Note [Add unfolding for scrutinee]. It had become detached, which led me on a bit of a wild goose chase. While I was at it, I made the code work right for the case where the scrutinee is of form (x |> co); I don't think this is an important improvement. I also make simplAlt unconditionally zap occurrence information on case-alternative binders (see Note [Case alternative occ info]); it was almost always being zapped and the additional complexity seems not worth it.

Make combine-identical-alternatives work again (Trac #7360) Move the "combine indentical alternatives" transformation *before* simplifying the alternatives. For example case x of y [] -> length y (_:_) -> length y } If we look *post* simplification, since 'y' is used in the alterantives, the case binders *might* be (see the keep_occ_info test in Simplify.simplAlt); and hence the combination of the two alteranatives does not happen. But if we do it *pre* simplification there is no problem. This fixes Trac #7360.

Simplify the binder-swap transformation The occurrence analyser implements the "binder-swap" transformation, described in Note [Binder swap] in OccAnal. For some reason I had implemeted an extremely complicated version, I believe intended to get as much as possible done in single simplifier pass. But it turned out (Trac #7258) that the 'getProxies' bit of this complicated code scaled rather non-linearly, and all by itself could consume half of the entire compile time. The patch dramatically simplifies the transformation, so that we simply swizzle case x of y { I# v -> e } to case x of y { I# v -> let x = y in e } I can't see any reason not to do this * Compiler allocation for #7258 with 200 fields goes down by 25% and compile time by 20% * The nofib figures do not budge * Quite a bit of complicated code goes away

Make {-# UNPACK #-} work for type/data family invocations This fixes most of Trac #3990. Consider data family D a data instance D Double = CD Int Int data T = T {-# UNPACK #-} !(D Double) Then we want the (D Double unpacked). To do this we need to construct a suitable coercion, and it's much safer to record that coercion in the interface file, lest the in-scope instances differ somehow. That in turn means elaborating the HsBang type to include a coercion. To do that I moved HsBang from BasicTypes to DataCon, which caused quite a few minor knock-on changes. Interface-file format has changed! Still to do: need to do knot-tying to allow instances to take effect within the same module.

Implement overlapping type family instances. An ordered, overlapping type family instance is introduced by 'type instance where', followed by equations. See the new section in the user manual (7.7.2.2) for details. The canonical example is Boolean equality at the type level: type family Equals (a :: k) (b :: k) :: Bool type instance where Equals a a = True Equals a b = False A branched family instance, such as this one, checks its equations in order and applies only the first the matches. As explained in the note [Instance checking within groups] in FamInstEnv.lhs, we must be careful not to simplify, say, (Equals Int b) to False, because b might later unify with Int. This commit includes all of the commits on the overlapping-tyfams branch. SPJ requested that I combine all my commits over the past several months into one monolithic commit. The following GHC repos are affected: ghc, testsuite, utils/haddock, libraries/template-haskell, and libraries/dph. Here are some details for the interested: - The definition of CoAxiom has been moved from TyCon.lhs to a new file CoAxiom.lhs. I made this decision because of the number of definitions necessary to support BranchList. - BranchList is a GADT whose type tracks whether it is a singleton list or not-necessarily-a-singleton-list. The reason I introduced this type is to increase static checking of places where GHC code assumes that a FamInst or CoAxiom is indeed a singleton. This assumption takes place roughly 10 times throughout the code. I was worried that a future change to GHC would invalidate the assumption, and GHC might subtly fail to do the right thing. By explicitly labeling CoAxioms and FamInsts as being Unbranched (singleton) or Branched (not-necessarily-singleton), we make this assumption explicit and checkable. Furthermore, to enforce the accuracy of this label, the list of branches of a CoAxiom or FamInst is stored using a BranchList, whose constructors constrain its type index appropriately. I think that the decision to use BranchList is probably the most controversial decision I made from a code design point of view. Although I provide conversions to/from ordinary lists, it is more efficient to use the brList... functions provided in CoAxiom than always to convert. The use of these functions does not wander far from the core CoAxiom/FamInst logic. BranchLists are motivated and explained in the note [Branched axioms] in CoAxiom.lhs. - The CoAxiom type has changed significantly. You can see the new type in CoAxiom.lhs. It uses a CoAxBranch type to track branches of the CoAxiom. Correspondingly various functions producing and consuming CoAxioms had to change, including the binary layout of interface files. - To get branched axioms to work correctly, it is important to have a notion of type "apartness": two types are apart if they cannot unify, and no substitution of variables can ever get them to unify, even after type family simplification. (This is different than the normal failure to unify because of the type family bit.) This notion in encoded in tcApartTys, in Unify.lhs. Because apartness is finer-grained than unification, the tcUnifyTys now calls tcApartTys. - CoreLinting axioms has been updated, both to reflect the new form of CoAxiom and to enforce the apartness rules of branch application. The formalization of the new rules is in docs/core-spec/core-spec.pdf. - The FamInst type (in types/FamInstEnv.lhs) has changed significantly, paralleling the changes to CoAxiom. Of course, this forced minor changes in many files. - There are several new Notes in FamInstEnv.lhs, including one discussing confluent overlap and why we're not doing it. - lookupFamInstEnv, lookupFamInstEnvConflicts, and lookup_fam_inst_env' (the function that actually does the work) have all been more-or-less completely rewritten. There is a Note [lookup_fam_inst_env' implementation] describing the implementation. One of the changes that affects other files is to change the type of matches from a pair of (FamInst, [Type]) to a new datatype (which now includes the index of the matching branch).

Implement overlapping type family instances. An ordered, overlapping type family instance is introduced by 'type instance where', followed by equations. See the new section in the user manual (7.7.2.2) for details. The canonical example is Boolean equality at the type level: type family Equals (a :: k) (b :: k) :: Bool type instance where Equals a a = True Equals a b = False A branched family instance, such as this one, checks its equations in order and applies only the first the matches. As explained in the note [Instance checking within groups] in FamInstEnv.lhs, we must be careful not to simplify, say, (Equals Int b) to False, because b might later unify with Int. This commit includes all of the commits on the overlapping-tyfams branch. SPJ requested that I combine all my commits over the past several months into one monolithic commit. The following GHC repos are affected: ghc, testsuite, utils/haddock, libraries/template-haskell, and libraries/dph. Here are some details for the interested: - The definition of CoAxiom has been moved from TyCon.lhs to a new file CoAxiom.lhs. I made this decision because of the number of definitions necessary to support BranchList. - BranchList is a GADT whose type tracks whether it is a singleton list or not-necessarily-a-singleton-list. The reason I introduced this type is to increase static checking of places where GHC code assumes that a FamInst or CoAxiom is indeed a singleton. This assumption takes place roughly 10 times throughout the code. I was worried that a future change to GHC would invalidate the assumption, and GHC might subtly fail to do the right thing. By explicitly labeling CoAxioms and FamInsts as being Unbranched (singleton) or Branched (not-necessarily-singleton), we make this assumption explicit and checkable. Furthermore, to enforce the accuracy of this label, the list of branches of a CoAxiom or FamInst is stored using a BranchList, whose constructors constrain its type index appropriately. I think that the decision to use BranchList is probably the most controversial decision I made from a code design point of view. Although I provide conversions to/from ordinary lists, it is more efficient to use the brList... functions provided in CoAxiom than always to convert. The use of these functions does not wander far from the core CoAxiom/FamInst logic. BranchLists are motivated and explained in the note [Branched axioms] in CoAxiom.lhs. - The CoAxiom type has changed significantly. You can see the new type in CoAxiom.lhs. It uses a CoAxBranch type to track branches of the CoAxiom. Correspondingly various functions producing and consuming CoAxioms had to change, including the binary layout of interface files. - To get branched axioms to work correctly, it is important to have a notion of type "apartness": two types are apart if they cannot unify, and no substitution of variables can ever get them to unify, even after type family simplification. (This is different than the normal failure to unify because of the type family bit.) This notion in encoded in tcApartTys, in Unify.lhs. Because apartness is finer-grained than unification, the tcUnifyTys now calls tcApartTys. - CoreLinting axioms has been updated, both to reflect the new form of CoAxiom and to enforce the apartness rules of branch application. The formalization of the new rules is in docs/core-spec/core-spec.pdf. - The FamInst type (in types/FamInstEnv.lhs) has changed significantly, paralleling the changes to CoAxiom. Of course, this forced minor changes in many files. - There are several new Notes in FamInstEnv.lhs, including one discussing confluent overlap and why we're not doing it. - lookupFamInstEnv, lookupFamInstEnvConflicts, and lookup_fam_inst_env' (the function that actually does the work) have all been more-or-less completely rewritten. There is a Note [lookup_fam_inst_env' implementation] describing the implementation. One of the changes that affects other files is to change the type of matches from a pair of (FamInst, [Type]) to a new datatype (which now includes the index of the matching branch). This seemed a better design. - The TySynInstD constructor in Template Haskell was updated to use the new datatype TySynEqn. I also bumped the TH version number, requiring changes to DPH cabal files. (That's why the DPH repo has an overlapping-tyfams branch.) - As SPJ requested, I refactored some of the code in HsDecls: * splitting up TyDecl into SynDecl and DataDecl, correspondingly changing HsTyDefn to HsDataDefn (with only one constructor) * splitting FamInstD into TyFamInstD and DataFamInstD and splitting FamInstDecl into DataFamInstDecl and TyFamInstDecl * making the ClsInstD take a ClsInstDecl, for parallelism with InstDecl's other constructors * changing constructor TyFamily into FamDecl * creating a FamilyDecl type that stores the details for a family declaration; this is useful because FamilyDecls can appear in classes but other decls cannot * restricting the associated types and associated type defaults for a * class to be the new, more restrictive types * splitting cid_fam_insts into cid_tyfam_insts and cid_datafam_insts, according to the new types * perhaps one or two more that I'm overlooking None of these changes has far-reaching implications. - The user manual, section 7.7.2.2, is updated to describe the new type family instances.

Use expectP in deriving( Read ) Note [Use expectP] in TcGenDeriv ~~~~~~~~~~~~~~~~~~ Note that we use expectP (Ident "T1") rather than Ident "T1" <- lexP The latter desugares to inline code for matching the Ident and the string, and this can be very voluminous. The former is much more compact. Cf Trac #7258, although that also concerned non-linearity in the occurrence analyser, a separate issue.

Redirect asynchronous exceptions to the sandbox thread in runStmt (#1381) See comment for details. We no longer use pushInterruptTargetThread/popInterruptTargetThread, so these could go away in due course.

Rename all of the 'cmmz' flags and make them more consistent. There's only a single compiler backend now, so the 'z' suffix means nothing. Also, the flags were confusingly named ('cmm-foo' vs 'foo-cmm',) and counter-intuitively, '-ddump-cmm' did not do at all what you expected since the new backend went live. Basically, all of the -ddump-cmmz-* flags are now -ddump-cmm-*. Some were renamed to be more consistent. This doesn't update the manual; it already mentions '-ddump-cmm' and that flag implies all the others anyway, which is probably what you want. Signed-off-by: Austin Seipp <mad.one@gmail.com>

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.

Move the kind Nat and Symbol out of TysPrim and into TysWiredIn They properly belong in TysWiredIn, since they are defined in Haskell in GHC.TypeLits. Moveover, make them WiredIn (again as they should be) and use checkWiredInTyCon when encountering them in TcHsType.tc_hs_type, so that the interface file is loaded. This fixes Trac #7502.

Call gcc with '-x assembler-with-cpp' instead of '-x assembler'. On x86 and powerpc, the second form above was ignoring all the CPP lines and hence trying to compile x86 asm on powerpc and powerpc asm on x86.

Major refactoring of the way that UNPACK pragmas are handled The situation was pretty dire. The way in which data constructors were handled, notably the mapping between their *source* argument types and their *representation* argument types (after seq'ing and unpacking) was scattered in three different places, and hard to keep in sync. Now it is all in one place: * The dcRep field of a DataCon gives its representation, specified by a DataConRep * As well as having the wrapper, the DataConRep has a "boxer" of type DataConBoxer (defined in MkId for loopy reasons). The boxer used at a pattern match to reconstruct the source-level arguments from the rep-level bindings in the pattern match. * The unboxing in the wrapper and the boxing in the boxer are dual, and are now constructed together, by MkId.mkDataConRep. This is the key function of this change. * All the computeBoxingStrategy code in TcTyClsDcls disappears. Much nicer. There is a little bit of refactoring left to do; the strange deepSplitProductType functions are now called only in WwLib, so I moved them there, and I think they could be tidied up further.

Change how sync-all handles directory changes We now remember the current working directory right at the start, and change back to it after we've finished working in a subdirectory. This should fix a problem some people have been seeing, where sync-all thinks that they have an out-of-date time library because its working directory has gone wrong somehow.

Vectoriser: distinguish vectorised from parallel types and functions - We sometimes need to vectorise types and functions because they might be needed in a vectorised context, not because they do directly introduce parallelism.

3:49 PM Changeset in ghc [1183080]ghc-7.6th-new-7.6 by Ian Lynagh <ian@…>
Stop attempting to "trim" data types in interface files Without -O, we previously tried to make interface files smaller by not including the data constructors of data types. But there are a lot of exceptions, notably when Template Haskell is involved or, more recently, DataKinds. However Trac #7445 shows that even without TemplateHaskell, using the Data class and invoking Language.Haskell.TH.Quote.dataToExpQ is enough to require us to expose the data constructors. So I've given up on this "optimisation" -- it's probably not important anyway. Now I'm simply not attempting to trim off the data constructors. The gain in simplicity is worth the modest cost in interface file growth, which is limited to the bits reqd to describe those data constructors. Conflicts: compiler/main/TidyPgm.lhs

Stop attempting to "trim" data types in interface files Without -O, we previously tried to make interface files smaller by not including the data constructors of data types. But there are a lot of exceptions, notably when Template Haskell is involved or, more recently, DataKinds. However Trac #7445 shows that even without TemplateHaskell, using the Data class and invoking Language.Haskell.TH.Quote.dataToExpQ is enough to require us to expose the data constructors. So I've given up on this "optimisation" -- it's probably not important anyway. Now I'm simply not attempting to trim off the data constructors. The gain in simplicity is worth the modest cost in interface file growth, which is limited to the bits reqd to describe those data constructors.
3:38 PM Changeset in base [9aa29b8]data-proxydbcsghc-7.8type-reasoning by Daniel Fischer <daniel.is.fischer@…>
Worker/Wrapper and static argument transform for `until` so it can be inlined With the direct top level recursion, `until` cannot be inlined by GHC, so no strictness analysis and consequently no unboxing occurs at the call site. With the recursion delegated to the worker with the condition and update function static arguments, it can be inlined, and strictness analysis can happen.

4:57 PM Changeset in ghc [b637a24d]ghc-7.6th-new-7.6 by Simon Peyton Jones <simonpj@…>
Fix Trac #7453 on the 7.6 branch This patch fixes a quite egregious bug. runTcS was intialising the 'untouchables' to NoUntouchables, which is quite wrong for the invocation in TcSimplify.simplifyInfer. Result: missed skolem-escape check and seg-fault city. All this is done differently, and better, in HEAD, so this patch is needed only on the branch.

In the next commit will be a README file in docs/core-spec with more details of how to do this.

Add ":info!" to GHCi. This shows all instances without filtering first. The default behavior of :info is to show only those instances of for a type, where all relevant type constructor names are in scope. This keeps down the number of instances shown to the user. In some cases, it is nice to be able to see all instances for a type. This patch implements this with the :info! command.

Only promote *non-existential* data constructors I don't konw how this was left out before; Trac #7347. In fixing this I did the usual round of refactoring. In particular, I cached the fact that a DataCon can be promoted in the DataCon itself (the dcPromoted field).

MERGED: Compare the kinds of type variables when comparing types commit 2c207b6f60ba5d271f400747256e4a32ca8f7e63 Author: Simon Peyton Jones <simonpj@microsoft.com> Date: Tue Oct 2 18:11:08 2012 +0100 Compare the kinds of type variables when comparing types This is just a bug that's been around since we introduced polymorphic kinds.

Make sure that we check for type errors strictly in a Template Haskell splice, even if -fdefer-type-errors is on We're going to run this code, so there's no point in deferring type errors. Worse, TcSplice uses unsafeCoerce (for vevy good reasons), so splicing a type into a place where an expression is expected would yield a seg-fault if we plough on regardless. Fixes Trac #7276

Fix the instantiation of data constructors in the GHCi debugger This bug caused Trac #7386, because in the (rather tricky) "type inference" (aka run time type reconstruction) done by the GHCi debugger, we were failing to instantiate a data type family correctly. When that code was written we didn't *have* data families. I wrote Note [Constructor arg types] to explain the new scheme.

Be lazier when typechecking data type contexts (Trac #7321) We should be lazy when type-checking the equality-contraint part of a data constructor's type, to make the knot-tying work out right. The fact that it's always worked before is a fluke: no one else wrote a GADT whose type index mentions itself data T a wher MkT :: T (T Int)

Ensure we produce a FunTy for functions (Trac #7312) The issue here was with a function type written prefix (->) a b where we were not generating a FunTy, which blew the invariant that function types are always FunTys. We can't look at the TyCon directly because it may be knot-tied, so we look at the name instead.
1:39 PM Changeset in ghc [162b87d]ghc-7.6th-new-7.6 by Ian Lynagh <ian@…>
rts: Ignore signal before deleting timer. Fixes #7303. Was getting an ocassional hang or segfault when building GHC in a Qemu user space emulation of ARM. Turned out that the ITIMER_SIGNAL was being delivered *after* the call to timer_delete(). Setting the signal to SIG_IGN before deleting the timer solves the problem.

Accurately report usage of newtype data constructors in FFI declarations See Note [Newtype constructor usage in foreign declarations] in TcForeign. It's quite non-trivial to say which newtype constructor are used in foreign import/export declarations, and I had to do a bit of refactoring to achieve it. (Say hello to the X5 bus from Oxford to Cambridge.) It's a bit tiresome, with some more plumbing, but not hard. Trac #7048 triggered this change.
