More work towards dynamic programs on Windows Dynamic GHC is now working in-place, but pathologically slow due to the DLL split. (GHC assumes that all intra-package calls are in the same DLL, but that isn't true when we split the GHC package into 2 DLLs. That means that GHC's startup time is around 22 seconds, as it is doing run-time linking). Also, ghci isn't actually working yet: $ inplace/bin/ghc-stage2 --interactive GHCi, version 7.7.20130512: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... <command line>: can't load .so/.DLL for: HSghc-prim-0.3.1.0.dll (addDLL: could not load DLL) ghc-stage2.exe: HSghc-prim-0.3.1.0: The specified module could not be found.

Change how we detect what library ways are available We used to use the base package to do the detection. However, base has extra-lib-dirs: @ICONV_LIB_DIRS@ in base.buildinfo.in, which means that if ICONV_LIB_DIRS is set then the package config will have library-dirs: [...]base/dist-install/build /path/for/iconv and, as paths may be double quoted and contains spaces, this makes it a little tricky to extra the path that we want to look in (the first path). We therefore now use the ghc-prim package, which has no such complication.

Fix dynamically linked GHC on Windows This is a rather ugly hack to fix dynamically linked GHC on Windows. If GHC is linked with -threaded, then it links against libHSrts_thr. But if base is linked against libHSrts, then both end up getting loaded, and things go wrong. We therefore link the libraries that link against the RTS with the same RTS flags that we link GHC with.

7:49 PM Changeset in base [f982978]data-proxyghc-7.8 by Max Bolingbroke <batterseapower@…>
Support for Windows DBCS and new SBCS with MultiByteToWideChar Because MultiByteToWideChar/WideCharToMultiByte have a rather unhelpful interface, we have to use a lot of binary searching tricks to get them to match the iconv-like interface that GHC requires. Even though the resulting encodings are slow, it does at least mean that we now support all of Window's code pages. What's more, since these codecs are basically only used for console output there probably won't be a huge volume of text to deal with in the common case, so speed is less of a worry. Note that we will still use GHC's faster table-based custom codec for supported SBCSs.

Update parallel IO manager to handle the invalid files in the same way as previous IO manager. This patch affects the IO manager using kqueue. See issue #7773. If the kqueue backend cannot wait for events on a file, it will simply call the registered callback for the file immediately. This is the behavior of the previous IO manager. This is not ideal, but it is an initial step toward dealing with the problem properly. Ideally, we would use a non-kqueue mechanism for waiting on files (select seems most reliable) that cannot be waited on with kqueue.

Added support for handling cases where SConts migrate capabilities. However, Sieve/ConcurrentListStealing.hs doesn't perform well when compared to Sieve/ConcurrentList.hs. Hmmm.. Perhaps it has to do with bound threads being stolen? Avoided migrating tso's hosting user-level schedulers (ULS) since there is a possibility that naive implementation of user-level schedulers will get stuck if it were not to account for SCont's (tso's) migrating between capabilities. Migration of ULS is safe, however.

Enable -funbox-small-strict-fields by default The flag shows no real impact on nofib benchmarks and GHC itself, which is expected given the small number of strict but not already unpacked fields in the source of these programs. However, the flag allows us to omit most of the UNPACK pragmas that are so common in source code today.

Suppress a misleading error message (Trac #7869) We were saying The function `f' is applied to one argument, but its type `[a] -> b' has only one which is obviously bogus. This fix suppresses the explanation in cases where it may not be the *right* explanation.

Exend the "Too few args" message for naked Ids (Trac #7851) Previously, for f :: [Bool] f = map not we'd get a helpful message Probable cause: ‛map’ is applied to too few arguments but not for f :: [Bool] f = map which seems a bit stupid.

Tighten up on the kind checking for foralls In particular, (forall a. Num a => ...) always has kind *, becuase the "=>" really is a function. It turned out that this was at the bottom of the crash in Trac #7778, which is now fixed

Disabled migration of threads running a user-level scheduler, without which sieve program seems to deadlock while running on a high core count. Enabling debug messages seems to make the bug disapper (Grr..). The error most probably is in RtsMessaging subsystem. Needs a different/better testcase.

Wibbles to error messages, following the fix for Trac #7851 In effect, the error context for naked variables now takes up a "slot" in the context stack; but it is often empty. So the context stack becomes one shorter in those cases. I don't think this matters; indeed, it's aguably an improvement. Anyway that's why so many tests are affected.

Remove some old "backwards compatibility" code It was marked as "backwards compatibility" in 2006, so I think can be removed now. It allowed using old field names when looking at fields with ghc-pkg.

If a thread running as a part of the user-level scheduler happens to block on a foreign call, and also happens to be bound, then we no longer resume the scheduler of such threads since the IOManager seems to not like it. See suspendThread, resumeThread, and shouldResumeBlockedOnForeignCall in rts/Schedule.c. This is an unsatisfactory solution since a bound thread performing a blocking foreign call blocks the scheduler! FIX ME!

Fix mismatched visibility of assembler impls of StgRun Based on a patch from PHO, in trac #7813. We were previously declaring StgRun as a private symbol (in rts/StgRun.h), but were actually defining it as a public one (in rts/StgCRun.c). This caused a linkage problem with old binutils.

In CMM, only allow foreign calls to labels, not arbitrary expressions I'm not sure if we want to make this change permanently, but for now it fixes the unreg build. I've also removed some redundant special-case code that generated prototypes for foreign functions. The standard pprTempAndExternDecls now generates them.

8:12 PM Changeset in base [631c4a3]dbcs by Max Bolingbroke <batterseapower@…>
Support for Windows DBCS and new SBCS with MultiByteToWideChar Because MultiByteToWideChar/WideCharToMultiByte have a rather unhelpful interface, we have to use a lot of binary searching tricks to get them to match the iconv-like interface that GHC requires. Even though the resulting encodings are slow, it does at least mean that we now support all of Window's code pages. What's more, since these codecs are basically only used for console output there probably won't be a huge volume of text to deal with in the common case, so speed is less of a worry. Note that we will still use GHC's faster table-based custom codec for supported SBCSs.

Peak-memory usage for T3064 varies depending on whether .hi file exists on not Really, the existence or otherwise of the .hi file shouldn't affect validate output, but it seems to. Maybe 'make clean' doesn't clean enough? In ay case peak memory usage is a fragile number because it depends on when GC happens. So I increased the range to 20% for now.

More accurate cost attribution for stacks. Fixes #7818. Previously, stacks were always attributed to CCCS_SYSTEM. Now, we attribute them to the CCS when the stack was allocated. If a stack grows, new stack chunks inherit the CCS of the old stack. Signed-off-by: Edward Z. Yang <ezyang@mit.edu>

Further wibbbling to type error message reporting * We now never report derived-constraint type errors, even in the "insolubles". See Note [Insoluble derived constraints] in TcRnTypes. * The cec_suppress mechanism in TcErrors is refactored a bit so that: - We suppress *all* errors in unreachable code (they can be jolly confusing) - We no longer suppress *all* non-insoluble errors if there are *any insolubles anywhere. Instead we are a bit more refined. See Note [Suppressing error messages] in TcErrors

Never unify a SigTyVar with a non-tyvar type (fixes Trac #7786) This unwanted unification was happening in the zonking phase which un-flattens type-function applications (TcMType.zonkFlats, try_zonk_fun_eq). The main unifier is careful to make the check, but I'd forgotten it here. That in turn led to a very confusing error message.

Implement faster System.Timeout.timeout for the threaded RTS. The basic idea is to use the Timer Manager rather than spawning an auxilliary thread to handle timeouts; this was proposed by Bas van Dijk two years ago (#4963), and recently by Herbert Valerio. The key idea to make this work is to spawn an auxilliary thread for the delivery of the Timeout exception. This idea as well as most of the code is due to Akio Takano.

Make the desugarer a tiny bit cleverer on coercions (fixes Trac #7837) The desugarer was generating a redundant box/unbox pair on the LHS of a RULE, which in turn made matching fail. See Note [Simple coercions] in DsBinds.

Merge b737a4 into the 7.6 branch, curing Trac #7748 The caching of goals in the constraint solver led to a equality-constraint loop even in a really simple program! commit b737a45391201fd475b89227ed1d7c9b72b24eea Author: Simon Peyton Jones <simonpj@microsoft.com> Date: Fri Aug 31 10:05:03 2012 +0100 More simplifications to the constraint solver * inert_solved becomes dictionaries-only, inert_solved_dicts * inert_solved_dicts is used only to cache the result of uses of a top level instance declaration, just like inert_solved_funeqs * That in turn simplifies xCtFlavor and rewriteCtFlavor, because they no longer need a "should I cache" parameter. (Moreover the settings for this parameter were very subtle; it's easy to get loops if you cache too much. Caching only top-level instance uses is much safer, and eliminates all these subtle cases.)

Fix the dynflags consistency code It was checking to see whether the hscTarget is HscC or HscLlvm, and changing it to HscC otherwise. But this meant that as well as rejecting HscAsm, it also rejected HscInterpreted and HscNothing. Now we just check whether it's HscAsm.

Fix type variable scoping in nested pattern type signatures (#7827)
11:01 AM Changeset in ghc [2eaf46fb]late-dmd by Nicolas Frisby <nicolas.frisby@…>
O2 now runs another demand analysis before CorePrep (fixes #7782) Its specific flag is -flate-dmd-anal The bulk of this patch merely simplifies the treatment of wrappers in inteface files. In particular, the body of a wrapper is now encoded (just like any other InlineStable) instead regenerating the wrapper from its strictness signature and worker id. Consequences: 0) simplifies a special case; there's plenty of knock-on code elimination from no longer having ids in UnfoldingSource 1) increases the size of .hi (some significantly, esp GHC.Classes) 2) increases compile time a bit (eg ~ +1% over nofib) 3) accomodates the late demand analysis: the previous treatment of wrappers in interface files caused CoreLint errors when combined with the second demand analysis
