ghc-pkg needs to be aware of platforms so it can figure out which subdire within the user package db to use. This is admittedly roundabout, but maybe Cabal could use the same notion of a platform as GHC to good affect too.

It never really encoded a invariant. * The linear register allocator just did partial pattern matches * The graph allocator just set it to (Just mapEmpty) for Nothing So I changed LiveInfo to directly contain the map. Further natCmmTopToLive which filled in Nothing is no longer exported. Instead we know call cmmTopLiveness which changes the type AND fills in the map.

The graph allocator now dynamically resizes the number of stack slots when running into the limit. This fixes #8657. Also loop membership of basic blocks is now available in the register allocator for cost heuristics.

It seems that most uses of these folds should be strict left folds (I could only find a single place that benefits from a right fold). So this removes the existing `setFold`/`mapFold`/`mapFoldWihKey` replaces them with: - `setFoldl`/`mapFoldl`/`mapFoldlWithKey` (strict left folds) - `setFoldr`/`mapFoldr` (for the less common case where a right fold actually makes sense, e.g., `CmmProcPoint`) Signed-off-by:

This switches the compiler/ component to get compiled with -XNoImplicitPrelude and a `import GhcPrelude` is inserted in all modules. This is motivated by the upcoming "Prelude" re-export of `Semigroup((<>))` which would cause lots of name clashes in every modulewhich imports also `Outputable` Reviewers: austin, goldfire, bgamari, alanz, simonmar Reviewed By: bgamari Subscribers: goldfire, rwbarton, thomie, mpickering, bgamari Differential Revision: https://phabricator.haskell.org/D3989

This copies the subset of Hoopl's functionality needed by GHC to `cmm/Hoopl` and removes the dependency on the Hoopl package. The main motivation for this change is the confusing/noisy interface between GHC and Hoopl: - Hoopl has `Label` which is GHC's `BlockId` but different than GHC's `CLabel` - Hoopl has `Unique` which is different than GHC's `Unique` - Hoopl has `Unique{Map,Set}` which are different than GHC's `Uniq{FM,Set}` - GHC has its own specialized copy of `Dataflow`, so `cmm/Hoopl` is needed just to filter the exposed functions (filter out some of the Hoopl's and add the GHC ones) With this change, we'll be able to simplify this significantly. It'll also be much easier to do invasive changes (Hoopl is a public package on Hackage with users that depend on the current behavior) This should introduce no changes in functionality - it merely copies the relevant code.

The fundamental problem with `type UniqSet = UniqFM` is that `UniqSet` has a key invariant `UniqFM` does not. For example, `fmap` over `UniqSet` will generally produce nonsense. * Upgrade `UniqSet` from a type synonym to a newtype. * Remove unused and shady `extendVarSet_C` and `addOneToUniqSet_C`. * Use cached unique in `tyConsOfType` by replacing `unitNameEnv (tyConName tc) tc` with `unitUniqSet tc`.

This continues removal of `BlockId` module in favor of Hoopl's `Label`. Most of the changes here are mechanical, apart from the orphan `Outputable` instances for `LabelMap` and `LabelSet`. For now I've moved them to `cmm/Hoopl`, since it's already trying to manage all imports from Hoopl (to avoid any collisions). Signed-off-by:

It seems that `BlockId` module could simply go away in favor of Hoopl's `Label`. This is the first step to do that. In a few places I had to add some type signatures, but most of them seem to help with code readability. Signed-off-by:

This documents nondeterminism in code generation and removes the nondeterministic ufmToList function. In the future someone will have to use nonDetEltsUFM (with proper explanation) or pprUFM.

This implements the ideas originally put forward in "System FC with Explicit Kind Equality" (ICFP'13). There are several noteworthy changes with this patch: * We now have casts in types. These change the kind of a type. See new constructor `CastTy`. * All types and all constructors can be promoted. This includes GADT constructors. GADT pattern matches take place in type family equations. In Core, types can now be applied to coercions via the `CoercionTy` constructor. * Coercions can now be heterogeneous, relating types of different kinds. A coercion proving `t1 :: k1 ~ t2 :: k2` proves both that `t1` and `t2` are the same and also that `k1` and `k2` are the same. * The `Coercion` type has been significantly enhanced. The documentation in `docs/core-spec/core-spec.pdf` reflects the new reality. * The type of `*` is now `*`. No more `BOX`. * Users can write explicit kind variables in their code, anywhere they can write type variables. For backward compatibility, automatic inference of kind-variable binding is still permitted. * The new extension `TypeInType` turns on the new user-facing features. * Type families and synonyms are now promoted to kinds. This causes trouble with parsing `*`, leading to the somewhat awkward new `HsAppsTy` constructor for `HsType`. This is dispatched with in the renamer, where the kind `*` can be told apart from a type-level multiplication operator. Without `-XTypeInType` the old behavior persists. With `-XTypeInType`, you need to import `Data.Kind` to get `*`, also known as `Type`. * The kind-checking algorithms in TcHsType have been significantly rewritten to allow for enhanced kinds. * The new features are still quite experimental and may be in flux. * TODO: Several open tickets: #11195, #11196, #11197, #11198, #11203. * TODO: Update user manual. Tickets addressed: #9017, #9173, #7961, #10524, #8566, #11142. Updates Haddock submodule.

This removes the OldCmm data type and the CmmCvt pass that converts new Cmm to OldCmm. The backends (NCGs, LLVM and C) have all been converted to consume new Cmm. The main difference between the two data types is that conditional branches in new Cmm have both true/false successors, whereas in OldCmm the false case was a fallthrough. To generate slightly better code we occasionally need to invert a conditional to ensure that the branch-not-taken becomes a fallthrough; this was previously done in CmmCvt, and it is now done in CmmContFlowOpt. We could go further and use the Hoopl Block representation for native code, which would mean that we could use Hoopl's postorderDfs and analyses for native code, but for now I've left it as is, using the old ListGraph representation for native code.

I observed that the [CmmStatics] within CmmData uses the list in a very stylised way. The first item in the list is almost invariably a CmmDataLabel. Many parts of the compiler pattern match on this list and fail if this is not true. This patch makes the invariant explicit by introducing a structured type CmmStatics that holds the label and the list of remaining [CmmStatic]. There is one wrinkle: the x86 backend sometimes wants to output an alignment directive just before the label. However, this can be easily fixed up by parameterising the native codegen over the type of CmmStatics (though the GenCmmTop parameterisation) and using a pair (Alignment, CmmStatics) there instead. As a result, I think we will be able to remove CmmAlign and CmmDataLabel from the CmmStatic data type, thus nuking a lot of code and failing pattern matches. This change will come as part of my next patch.

This changes the new code generator to make use of the Hoopl package for dataflow analysis. Hoopl is a new boot package, and is maintained in a separate upstream git repository (as usual, GHC has its own lagging darcs mirror in http://darcs.haskell.org/packages/hoopl). During this merge I squashed recent history into one patch. I tried to rebase, but the history had some internal conflicts of its own which made rebase extremely confusing, so I gave up. The history I squashed was: - Update new codegen to work with latest Hoopl - Add some notes on new code gen to cmm-notes - Enable Hoopl lag package. - Add SPJ note to cmm-notes - Improve GC calls on new code generator. Work in this branch was done by: - Milan Straka <fox@ucw.cz> - John Dias <dias@cs.tufts.edu> - David Terei <davidterei@gmail.com> Edward Z. Yang <ezyang@mit.edu> merged in further changes from GHC HEAD and fixed a few bugs.

* I've pushed the SPILL and RELOAD instrs down into the LiveInstr type to make them easier to work with. * When the graph allocator does a spill cycle it now just re-annotates the LiveCmmTops instead of converting them to NatCmmTops and back. * This saves working out the SCCS again, and avoids rewriting the SPILL and RELOAD meta instructions into real machine instructions.

* The old Reg type is now split into VirtualReg and RealReg. * For the graph coloring allocator, the type of the register graph is now (Graph VirtualReg RegClass RealReg), which shows that it colors in nodes representing virtual regs with colors representing real regs. (as was intended) * RealReg contains two contructors, RealRegSingle and RealRegPair, where RealRegPair is used to represent a SPARC double reg constructed from two single precision FP regs. * On SPARC we can now allocate double regs into an arbitrary register pair, instead of reserving some reg ranges to only hold float/double values.

- nativeGen/Instruction defines a type class for a generic instruction set. Each of the instruction sets we have, X86, PPC and SPARC are instances of it. - The register alloctors use this type class when they need info about a certain register or instruction, such as regUsage, mkSpillInstr, mkJumpInstr, patchRegs.. - nativeGen/Platform defines some data types enumerating the architectures and operating systems supported by the native code generator. - DynFlags now keeps track of the current build platform, and the PositionIndependentCode module uses this to decide what to do instead of relying of #ifdefs. - It's not totally retargetable yet. Some info info about the build target is still hardwired, but I've tried to contain most of it to a single module, TargetRegs. - Moved the SPILL and RELOAD instructions into LiveInstr. - Reg and RegClass now have their own modules, and are shared across all architectures.
