Always pass vector values on the stack. Vector values are now always passed on the stack. This isn't particularly efficient, but it will have to do for now.

Add the Float32X4# primitive type and associated primops. This patch lays the groundwork needed for primop support for SIMD vectors. In addition to the groundwork, we add support for the FloatX4# primitive type and associated primops. * Add the FloatX4# primitive type and associated primops. * Add CodeGen support for Float vectors. * Compile vector operations to LLVM vector operations in the LLVM code generator. * Make the x86 native backend fail gracefully when encountering vector primops. * Only generate primop wrappers for vector primops when using LLVM.

Add support for passing SSE vectors in registers. This patch adds support for 6 XMM registers on x86-64 which overlap with the F and D registers and may hold 128-bit wide SIMD vectors. Because there is not a good way to attach type information to STG registers, we aggressively bitcast in the LLVM back-end.

Mimic OldCmm basic block ordering in the LLVM backend. In OldCmm, the false case of a conditional was a fallthrough. In Cmm, conditionals have both true and false successors. When we convert Cmm to LLVM, we now first re-order Cmm blocks so that the false successor of a conditional occurs next in the list of basic blocks, i.e., it is a fallthrough, just like it (necessarily) did in OldCmm. Surprisingly, this can make a big performance difference.

Define __GLASGOW_HASKELL_LLVM__ when using the LLVM back end. When compiling via LLVM, GHC now defines the CPP symbol __GLASGOW_HASKELL_LLVM__ to the version of LLVM used, e.g., __GLASGOW_HASKELL_LLVM__ is defined to be 30 for LLVM version 3.0.

We should be including HaskellMachRegs.h here, not RtsMachRegs.h This was causing GenApply.hs to use the host architecture's register settings rather than the target's, with the result that some cross-compiled programs would crash.

Add support for *named* holes; an extension of -XTypeHoles The idea is that you can use "_foo" rather than just "_" as a "hole" in an expression, and this name shows up in type errors etc. The changes are very straightforward. Thanks for Thijs Alkemade for making the running here.

STM: Only wake up once Previously, threads blocked on an STM retry would be sent a wakeup message each time an unpark was requested. This could result in the accumulation of a large number of wake-up messages, which would slow wake-up once the sleeping thread is finally scheduled. Here, we introduce a new closure type, STM_AWOKEN, which marks a TSO which has been sent a wake-up message, allowing us to send only one wakeup.

Improve consistency checking for associated type-family instances The "consistency" in this case is beteween the instance head and the associated type instance head, which is made trickier by the presence of kind variables that are not explicitly mentioned in the class head. See Note [Checking consistent instantiation] in TcInstDcls This fixes Trac #7282.

StaticFlags code cleanup (fixes #7595) Function responsible for parsing the static flags, that were spread across two modules (StaticFlags and StaticFlagParser), are now in one file.

More refactoring of FamInst/FamInstEnv; finally fixes Trac #7524 Quite a bit of tidying up here; the fix to #7524 is actually only a small part. * Be fully clear that the cab_tvs in a CoAxBranch are not fresh. See Note [CoAxBranch type variables] in CoAxiom. * Use CoAxBranch to replace the ATDfeault type in Class. CoAxBranch is perfect here. This change allowed me to delete quite a bit of boilerplate code, including the corresponding IfaceSynType. * Tidy up the construction of CoAxBranches, and when FamIntBranch is freshened. The latter onw happens only in FamInst.newFamInst. * Tidy the tyvars of a CoAxBranch when we build them, done in FamInst.mkCoAxBranch. See Note [Tidy axioms when we build them] in that module. This is what fixes #7524. Much niceer now.

Fix documentation bug: TSOs are *not* unconditionally kept on the mutable list. The bug where TSOs were unconditionally kept on the mutable list was #1589 which was fixed in 04cddd339c000df6d02c90ce59dbffa58d2fe166. Curiously enough, the commit that changed this comment 0417404f5d1230c9d291ea9f73e2831121c8ec99 occurred *after* this change was made; I can only assume Simon Marlow accidentally forgot that he had fixed this bug. :-) Signed-off-by: Edward Z.

use -e rather than -d when checking for the existence of a subrepo The .git file in a submodule's root directory is not necessarily a directory, as is the case for the 'time' submodule. This fixes #7577, where some './sync-all' operations don't detect that the 'time' submodule is present in the repository.

Refactor and improve the promotion inference It should be the case that either an entire mutually recursive group of data type declarations can be promoted, or none of them. It's really odd to promote some data constructors of a type but not others. Eg data T a = T1 a | T2 Int Here T1 is sort-of-promotable but T2 isn't (becuase Int isn't promotable). This patch makes it all-or-nothing. At the same time I've made the TyCon point to its promoted cousin (via the tcPromoted field of an AlgTyCon), as well as vice versa (via the ty_con field of PromotedTyCon). The inference for the group is done in TcTyDecls, the same place that infers which data types are recursive, another global question.

Introduce CPR for sum types (Trac #5075) The main payload of this patch is to extend CPR so that it detects when a function always returns a result constructed with the *same* constructor, even if the constructor comes from a sum type. This doesn't matter very often, but it does improve some things (results below). Binary sizes increase a little bit, I think because there are more wrappers. This with -split-objs. Without split-ojbs binary sizes increased by 6% even for HelloWorld.hs. It's hard to see exactly why, but I think it was because System.Posix.Types.o got included in the linked binary, whereas it didn't before.

Fix our handling of literals and types in LLVM (#7575). This bug was introduced in the recent fix for #7571, that extended some existing infastructure in the LLVM backend that handled the conflict between LLVM's return type from comparison operations (i1) and what GHC expects (word). By extending it to handle literals though, we forced all literals to be i1 or word, breaking other code. This patch resolves this breakage and handles #7571 still, cleaning up the code for both a little. The overall approach is not ideal but changing that is left for the future.

Ensure the LLVM codegen correctly handles literals in a branch. #7571 We need to be sure that when generating code for literals, we properly narrow the type of the literal to i1. See Note [Literals and branch conditions] in the LlvmCodeGen.CodeGen module. This occurs rarely as the optimizer will remove conditional branches with literals, however we can get this situation occurring with hand written Cmm code. This fixes Trac #7571.

Minor impovement to when we float a let out of a right-hand side: Note [Float when cheap or expandable] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We want to float a let from a let if the residual RHS is a) cheap, such as (\x. blah) b) expandable, such as (f b) if f is CONLIKE But there are - cheap things that are not expandable (eg \x. expensive) - expandable things that are not cheap (eg (f b) where b is CONLIKE) so we must take the 'or' of the two.

Tidy up cross-compiling We have two cases: 1. building a cross-compiler 2. compiling GHC to run on a foreign platform These two are done with almost the same setup: (1) is the stage 1 compiler, and (2) is the stage 2 compiler, when CrossCompiling=YES. The only difference between (1) and (2) is that you if you set up the build for (1), then it stops before stage 2 and you can 'make install' to install stage 1. Unfortunately, (2) didn't work, and the build system code needed some tidying up. Change to the way the build is set up: Before ------ To build a cross-compiler: ./configure --target=<..> To compile a foreign GHC: ./configure --host=<..> --target=<..> Now --- To build a cross-compiler: ./configure --target=<..> And set "Stage1Only=YES" in mk/build.mk To compile a foreign GHC: ./configure --target=<..>

A simple improvement to CSE See Note [CSE for case expressions]. I don't think this is a big deal, but it's nice, and it's easy.

Major patch to implement the new Demand Analyser This patch is the result of Ilya Sergey's internship at MSR. It constitutes a thorough overhaul and simplification of the demand analyser. It makes a solid foundation on which we can now build. Main changes are * Instead of having one combined type for Demand, a Demand is now a pair (JointDmd) of - a StrDmd and - an AbsDmd. This allows strictness and absence to be though about quite orthogonally, and greatly reduces brain melt-down. * Similarly in the DmdResult type, it's a pair of - a PureResult (indicating only divergence/non-divergence) - a CPRResult (which deals only with the CPR property * In IdInfo, the strictnessInfo field contains a StrictSig, not a Maybe StrictSig demandInfo field contains a Demand, not a Maybe Demand We don't need Nothing (to indicate no strictness/demand info) any more; topSig/topDmd will do. * Remove "boxity" analysis entirely. This was an attempt to avoid "reboxing", but it added complexity, is extremely ad-hoc, and makes very little difference in practice. * Remove the "unboxing strategy" computation. This was an an attempt to ensure that a worker didn't get zillions of arguments by unboxing big tuples. But in fact removing it DRAMATICALLY reduces allocation in an inner loop of the I/O library (where the threshold argument-count had been set just too low). It's exceptional to have a zillion arguments and I don't think it's worth the complexity, especially since it turned out to have a serious performance hit. * Remove quite a bit of ad-hoc cruft * Move worthSplittingFun, worthSplittingThunk from WorkWrap to Demand. This allows JointDmd to be fully abstract, examined only inside Demand. Everything else really follows from these changes. All of this is really just refactoring, so we don't expect big performance changes, but acutally the numbers look quite good. Here is a full nofib run with some highlights identified: Program Size Allocs Runtime Elapsed TotalMem -------------------------------------------------------------------------------- expert -2.6% -15.5% 0.00 0.00 +0.0% fluid -2.4% -7.1% 0.01 0.01 +0.0% gg -2.5% -28.9% 0.02 0.02 -33.3% integrate -2.6% +3.2% +2.6% +2.6% +0.0% mandel2 -2.6% +4.2% 0.01 0.01 +0.0% nucleic2 -2.0% -16.3% 0.11 0.11 +0.0% para -2.6% -20.0% -11.8% -11.7% +0.0% parser -2.5% -17.9% 0.05 0.05 +0.0% prolog -2.6% -13.0% 0.00 0.00 +0.0% puzzle -2.6% +2.2% +0.8% +0.8% +0.0% sorting -2.6% -35.9% 0.00 0.00 +0.0% treejoin -2.6% -52.2% -9.8% -9.9% +0.0% -------------------------------------------------------------------------------- Min -2.7% -52.2% -11.8% -11.7% -33.3% Max -1.8% +4.2% +10.5% +10.5% +7.7% Geometric Mean -2.5% -2.8% -0.4% -0.5% -0.4% Things to note * Binary sizes are smaller. I don't know why, but it's good. * Allocation is sometiemes a *lot* smaller. I believe that all the big numbers (I checked treejoin, gg, sorting) arise from one place, namely a function GHC.IO.Encoding.UTF8.utf8_decode, which is strict in two Buffers both of which have several arugments. Not w/w'ing both arguments (which is what we did before) has a big effect. So the big win in actually somewhat accidental, gained by removing the "unboxing strategy" code. * A couple of benchmarks allocate slightly more. This turns out to be due to reboxing (integrate). But the biggest increase is mandel2, and *that* turned out also to be a somewhat accidental loss of CSE, and pointed the way to doing better CSE: see Trac #7596. * Runtimes are never very reliable, but seem to improve very slightly. All in all, a good piece of work. Thank you Ilya!

Fix Trac #7585. The coercion optimizer was optimizing coercions inside of branched axiom applications, sometimes invalidating the branch choice within the axiom application. Now, we check to make sure we are not invalidating this invariant before proceeding with the optimization.

Use a version of the coverage condition even with UndecidableInstances. This fixes bug #1241 and #2247. When UndecidableInstances are on, we use the "Liberal Coverage Condition", which is what GHC used to do in the past. This is the gist of the check: class C a b | a -> b instance theta => C t1 t2 we check that `fvs t2` is a subset of `fd-closure(theta,fvs t1)`. This is strictly more general than the coverage condition, while it still guarantees consistency with the FDs of the class. This check is completely orthogonal to termination (it by no means guarantees it). I am not sure of the role of the "coverage condition" in termination--- the comments suggest that it is important. This is why, for the moment, we only use this check when UndecidableInstances are on.

Fix Trac #7560. Code in conflictInstErr did not handle the case where some branches of a branched family instance had an error and some didn't. It was all or nothing. Now, if there are no conflicts for a given branch, conflictInstErr just ignores the branch instead of panicking.

Re-engineer the ambiguity test for user type signatures Two main changes. First, re-engineer the ambiguity test. Previously TcMType.checkAmbiguity used a rather syntactic test to detect some types that are certainly ambiguous. But a much easier test is available, and it is used for inferred types in TcBinds. Namely <type> is ambiguous iff <type> `TcUnify.isSubType` <type> fails to hold, where "isSubType" means "is provably more polymorphic than". Example: C a => Int is ambiguous, because isSubType instantiates the (C a => Int) to (C alpha => Int) and then tries to deduce (C alpha) from (C a). This is Martin Sulzmann's definition of ambiguity. (Defn 10 of "Understanding functional dependencies via constraint handling rules", JFP.) This change is neat, reduces code, and correctly rejects more programs. However is *is* just possible to have a useful program that would be rejected. For example class C a b f :: C Int b => Int -> Int Here 'f' would be rejected as having an ambiguous type. But it is just possible that, at a *call* site there might be an instance declaration instance C Int b, which does not constrain 'b' at all. This is pretty strange -- why is 'b' overloaded at all? -- but it's possible, so I also added a flag -XAllowAmbiguousTypes that simply removes the ambiguity check. Let's see if anyone cares. Meanwhile the earlier error report will be useful for everyone else. A handful of regression tests had to be adjusted as a result, because they used ambiguous types, somewhat accidentally. Second, split TcMType (already too large) into two * TcMType: a low-level module dealing with monadic operations like zonking, creating new evidence variables, etc * TcValidity: a brand-new higher-level module dealing with validity checking for types: checkValidType, checkValidInstance, checkFamInstPats etc Apart from the fact that TcMType was too big, this allows TcValidity to import TcUnify(tcSubType) without causing a loop.

Fix bugs in allocMoreStack (#7498, #7510) There were four bugs here. Clearly I didn't test this enough to expose the bugs - it appeared to work on x86/Linux, but completely by accident it seems. 1. the delta was wrong by a factor of the slot size (as noted on #7498) 2. we weren't correctly aligning the stack pointer (sp needs to be 16-byte aligned on x86/x86_64) 3. we were doing the adjustment multiple times in the case of a block that was both a return point and a local branch target. To fix this I had to add new shim blocks to adjust the stack pointer, and retarget the original branches. See comment for details. 4. we were doing the adjustment for CALL instructions, which is unnecessary and wrong; only JMPs should be preceded by a stack adjustment. (Someone with a PPC box will need to update the PPC version of allocMoreStack to fix the above bugs, using the x86 version as a guide.)

Refactor invariants for FamInsts. This commit mirrors work done in the commit for ClsInsts, 5efe9b... Specifically: - All FamInsts have *fresh* type variables. So, no more freshness work in addLocalFamInst Also: - Some pretty-printing code around FamInsts was cleaned up a bit This caused location information to be added to CoAxioms and index information to be added to FamInstBranches.

Add a -rpath entry for the RTS library, so that it can find libffi This fixes dynamic library resolution when --enable-new-dtags is used (#7062). When --enable-new-dtags is used when linking an executable, a RUNPATH as well as RPATH is set. The linker then ignores RPATH, and RUNPATH is only used for directly (not transitively) needed libraries. As the program doesn't directly need libffi, it isn't found.

Changed deriving of Functor, Foldable, Traversable to fix #7436. Added foldMap to derived Foldable instance. The derived instances will no longer eta-expand the function. I.e. instead of fmap f (Foo a) = Foo (fmap (\x -> f x) a) we now derive fmap f (Foo a) = Foo (fmap f a) Some superflous lambdas are generated as a result. For example data X a = X (a,a) fmap f (X x) = (\y -> case y of (a,b) -> (f a, f b)) x The optimizer should be able to simplify this code, as it is just beta reduction. The derived Foldable instance now includes foldMap in addition to foldr.

Refactor HsExpr.MatchGroup * Make MatchGroup into a record, and use the record fields * Split the type field into two: mg_arg_tys and mg_res_ty This makes life much easier for the desugarer when the case alterantives are empty A little bit of this change unavoidably ended up in the preceding commit about empty case alternatives

Allow empty case expressions (and lambda-case) with -XEmptyCase The main changes are: * Parser accepts empty case alternatives * Renamer checks that -XEmptyCase is on in that case * (Typechecker is pretty much unchanged.) * Desugarer desugars empty case alternatives, esp: - Match.matchWrapper and Match.match now accept empty eqns - New function matchEmpty deals with the empty case - See Note [Empty case alternatives] in Match This patch contains most of the work, but it's a bit mixed up with a refactoring of MatchGroup that I did at the same time (next commit).

Make CaseElim a bit less aggressive See Note [Case elimination: lifted case]: We used to do case elimination if (c) the scrutinee is a variable and 'x' is used strictly But that changes case x of { _ -> error "bad" } --> error "bad" which is very puzzling if 'x' is later bound to (error "good"). Where the order of evaluation is specified (via seq or case) we should respect it. c.f. Note [Empty case alternatives] in CoreSyn, which is how I came across this.

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.
