866 In standalone deriving, we now do *not* check side conditions.
867 We simply generate the code and typecheck it.  If there's a type
868 error, it's the programmer's problem.
869 
870 This means that you can do 'deriving instance Show (T a)', where
871 T is a GADT, for example, provided of course that the boilerplate
872 code does in fact typecheck.
873 
874 I put some work into getting a decent error message.  In particular
875 if there's a type error in a method, GHC will show the entire code
876 for that method (since, after all, the user did not write it).
877 Most of the changes are to achieve that goal.
878 
879 Still to come: changes in the documentation.

967 Now, for a compiler-generated binding "x", if "x" is referred to by
968 the exported "f", then it will be named "f_x" rather than something
969 like "x23".  This means that hopefully
970 
971   - compilation will more often product the same results given the
972     same input (the choice of names is not dependent on the
973     non-deterministic order of bindings within the compiler).
974 
975   - less recompilation will be necessary after making changes
976 
977   - navigating Core might be a bit easier.
978 
979 unfortunately, compilation with -O still does not consistently produce
980 the same ABI.  The simplifier sometimes does different things,

998 When matching against a GADT, some of the constructors may be impossible.
999 For example
1000        data T a where
1001           T1 :: T Int
1002           T2 :: T Bool
1003           T3 :: T a
1004 
1005         f :: T Int -> Int
1006         f T1 = 3
1007         f T3 = 4
1008 
1009 Here, does not have any missing cases, despite omittting T2, because
1010 T2 :: T Bool.
1011 
1012 This patch teaches the overlap checker about GADTs, which happily

1088 2 reasons for this:
1089   - compilation is more predictable.  Adding or removing an instance
1090     is less likely to force unnecessary recompilation due to
1091     renumbering other dfun names.
1092   - it makes it easier to read Core / C-- / asm
1093 
1094 The names aren't completely deterministic.  To do that, we'd have to
1095 include package and module names, which would make the symbol names
1096 long and reduce readability.  So the compromise is that if there's a
1097 clash, we disambiguate by adding an integer suffix.  This is fairly
1098 unlikely in practice unless you're using overlapping instances.
1099 
1100 Type family instances are handled in the same way, with the same
1101 disambiguation strategy.

1341 
1342 The main purpose of this patch is to fix Trac #3306, by fleshing out the
1343 syntax for GADT-style record declraations so that you have a context in
1344 the type.  The new form is
1345    data T a where
1346      MkT :: forall a. Eq a => { x,y :: !a } -> T a
1347 See discussion on the Trac ticket.
1348 
1349 The old form is still allowed, but give a deprecation warning.
1350 
1351 When we remove the old form we'll also get rid of the one reduce/reduce
1352 error in the grammar. Hurrah!
1353 
1354 While I was at it, I failed as usual to resist the temptation to do lots of
1355 refactoring.  The parsing of data/type declarations is now much simpler and
1356 more uniform.  Less code, less chance of errors, and more functionality.
1357 Took longer than I planned, though.
1358 
1359 ConDecl has record syntax, but it was not being used consistently, so I
1360 pushed that through the compiler.

1455 Behind the scenes, the new IO library always does buffering for read
1456 Handles regardless of NoBuffering.  Normally this isn't visible, but
1457 it causes a problem in GHCi where there are two stdin Handles.

1465 Previously this rule had a sanity check for the existence of the .o

1625 We need this, or something equivalent, to be able to implement
1626 stgAllocForGMP outside of the rts. That's because we want to use
1627 allocateLocal which allocates from the given capability without
1628 having to take any locks. In the gmp primops we're basically in
1629 an unsafe foreign call, that is a context where we hold a current
1630 capability. So it's safe for us to use allocateLocal. We just
1631 need a way to get the current capability. The method to get the
1632 current capability varies depends on whether we're using the
1633 threaded rts or not. When stgAllocForGMP is built inside the rts
1634 that's ok because we can do it conditionally on THREADED_RTS.
1635 Outside the rts we need a single api we can call without knowing
1636 if we're talking to a threaded rts or not, hence this addition.

1652 Just in case we decide it means something later it's better to stick
1653 to using one or the other consistently. We decided that using safe

1656[Add PrimCall to the STG layer and update Core -> STG translation

1658 It adds a third case to StgOp which already hold StgPrimOp and StgFCallOp.
1659 The code generation for the new StgPrimCallOp case is almost exactly the
1660 same as for out-of-line primops. They now share the tailCallPrim function.
1661 In the Core -> STG translation we map foreign calls using the "prim"
1662 calling convention to the StgPrimCallOp case. This is because in Core we
1663 represent prim calls using the ForeignCall stuff. At the STG level however
1664 the prim calls are really much more like primops than foreign calls.

1666[Desugaring for "foreign import prim"
1667Duncan Coutts <duncan@well-typed.com>**20090609105945
1668 Unlike normal foreign imports which desugar into a separate worker and
1669 wrapper, we use just a single wrapper decleration. The representation
1670 in Core of the call is currently as a foreign call. This means the
1671 args are all treated as fully strict. This is ok at the moment because
1672 we restrict the types for foreign import prim to be of unboxed types,
1673 however in future we may want to make prim imports be the normal cmm
1674 calling convention for Haskell functions, in which case we would not
1675 be able to assume all args are strict. At that point it may make more
1676 sense to represent cmm/prim calls distinct from foreign calls, and
1677 more like the we the existing PrimOp calls are handled.

1681 The main restriction is that all args and results must be unboxed types.
1682 In particular we allow unboxed tuple results (which is a primary
1683 motivation for the whole feature). The normal rules apply about
1684 "void rep" result types like State#. We only allow "prim" calling
1685 convention for import, not export. The other forms of import, "dynamic",
1686 "wrapper" and data label are banned as a conseqence of checking that the
1687 imported name is a valid C string. We currently require prim imports to
1688 be marked unsafe, though this is essentially arbitrary as the safety
1689 information is unused.

1755 * When linking a shared library with --make, always do the link step

1847 
1848 Roman found situations where he had
1849       case (f n) of _ -> e
1850 where he knew that f (which was strict in n) would terminate if n did.
1851 Notice that the result of (f n) is discarded. So it makes sense to
1852 transform to
1853       case n of _ -> e
1854 
1855 Rather than attempt some general analysis to support this, I've added
1856 enough support that you can do this using a rewrite rule:
1857 
1858   RULE "f/seq" forall n.  seq (f n) e = seq n e
1859 
1860 You write that rule.  When GHC sees a case expression that discards
1861 its result, it mentally transforms it to a call to 'seq' and looks for
1862 a RULE.  (This is done in Simplify.rebuildCase.)  As usual, the
1863 correctness of the rule is up to you.
1864 
1865 This patch implements the extra stuff.  I have not documented it explicitly
1866 in the user manual yet... let's see how useful it is first.

1869   a) Comments; see esp MkId Note [seqId magic]
1870 
1871   b) Some refactoring.  Notably, I moved the special desugaring for
1872      seq from MkCore back into DsUtils where it properly belongs.
1873      (It's really a desugaring thing, not a CoreSyn invariant.)
1874 
1875   c) Annoyingly, in a RULE left-hand side we need to be careful that
1876      the magical desugaring done in MkId Note [seqId magic] item (c)
1877      is *not* done on the LHS of a rule. Or rather, we arrange to
1878      un-do it, in DsBinds.decomposeRuleLhs.

1972 
1973 The new flag -XMonoLocalBinds tells GHC not to generalise nested
1974 bindings in let or where clauses, unless there is a type signature,
1975 in which case we use it. 
1976 
1977 I'm thinking about whether this might actually be a good direction for
1978 Haskell go to in, although it seems pretty radical.  Anyway, the flag
1979 is easy to implement (look at how few lines change), and having it
1980 will allow us to experiement with and without.

2040simonpj@microsoft.com**20090529072020
2041 Ignore-this: 3c762bda546981c4b4f01d28b8586ff8
2042 
2043 This patch fixes an insidious and long-standing bug in the way that
2044 parallelism is handled in GHC.  See Note [lazyId magic] in MkId.
2045 
2046 Here's the diagnosis, copied from the Trac ticket.  par is defined
2047 in GHC.Conc thus:
2048 
2049     {-# INLINE par  #-}
2050     par :: a -> b -> b
2051     par  x y = case (par# x) of { _ -> lazy y }
2052 
2053     -- The reason for the strange "lazy" call is that it fools the
2054     -- compiler into thinking that pseq and par are non-strict in
2055     -- their second argument (even if it inlines pseq/par at the call
2056     -- site).  If it thinks par is strict in "y", then it often
2057     -- evaluates "y" before "x", which is totally wrong.
2058 
2059 The function lazy is the identity function, but it is inlined only
2060 after strictness analysis, and (via some magic) pretends to be
2061 lazy. Hence par pretends to be lazy too.
2062 
2063 The trouble is that both par and lazy are inlined into your definition
2064 of parallelise, so that the unfolding for parallelise (exposed in
2065 Parallelise.hi) does not use lazy at all. Then when compiling Main,
2066 parallelise is in turn inlined (before strictness analysis), and so
2067 the strictness analyser sees too much.
2068 
2069 This was all sloppy thinking on my part. Inlining lazy after
2070 strictness analysis works fine for the current module, but not for
2071 importing modules.
2072 
2073 The fix implemented by this patch is to inline 'lazy' in CorePrep,
2074 not in WorkWrap. That way interface files never see the inlined version.
2075 
2076 The downside is that a little less optimisation may happen on programs
2077 that use 'lazy'.  And you'll only see this in the results -ddump-prep
2078 not in -ddump-simpl.  So KEEP AN EYE OUT (Simon and Satnam especially).
2079 Still, it should work properly now.  Certainly fixes #3259.

2254 At last!  Trac #1476 and #3177

2257 types.  For example
2258 
2259   f :: Int -> $(burble 3)
2260 
2261 A type splice should work anywhere a type is expected.  This feature
2262 has been long requested, and quite a while ago I'd re-engineered the
2263 type checker to make it easier, but had never got around to finishing
2264 the job.  With luck, this does it.
2265 
2266 There's a ToDo in the HsSpliceTy case of RnTypes.rnHsType, where I

2277 When you have a (\s::String -> ....[| s |]....), the string
2278 's' is lifted.  We used to get a chain of single-character
2279 Cons nodes, correct but lots and lots of code. 
2280 
2281 This patch arranges to optimise that to a string literal. It does
2282 so in two places:
2283   a) In TcExpr, if we know that s::String, we generate liftString directly
2284   b) In DsMeta, if we find a list of character literals, we convert to
2285      a string.  This catches a few cases that (a) does not

2418 it makes sense for --make to not try and link a binary when there

2453 Previously the object code for the C main function lived in the rts

2455 With Windows DLLs it always causes problems while on ELF systems it's a
2456 problem when the user decides to use their own C main function rather
2457 than a Haskell Main.main. So instead we now put main in it's own tiny
2458 little static lib libHSrtsmain.a which we install next to the rts libs.
2459 Whenever ghc links a program (without -no-hs-main) then it also links
2460 in -lHSrtsmain. For consistency we always do it this way now rather
2461 than trying to do it differently for static vs shared libraries.

2467 It had to do that because Windows DLLs are stricter about unresolved symbols

2658 desugaring and typechecking that!
2659 
2660 Anyway, the bug here is that to compute the 'fixed' type variables I was
2661 only looking at one constructor rather than all the relevant_cons

2677Duncan Coutts <duncan@well-typed.com>**20090501235824
2678 When using shared libs we should link each lib against its deps. This allows
2679 the dynamic linker to chase dependencies and means we do not have to specify
2680 all indirect dependencies (as we must do for static libs).

2682[Make ghc -dynamic imply -fPIC for C code
2683Duncan Coutts <duncan@well-typed.com>**20090501121445
2684 As is already the case for ghc -fPIC. This is needed because ghc -dynamic
2685 means to generate code that is capable of being linked to Haskell shared
2686 libs and for C code the equivalent is -fPIC. Normally C code does not need
2687 -fPIC merely to link to shared libs however Haskell shared libs do not
2688 follow common conventions. In particular the static data cannot be
2689 referenced statically because it cannot be copied by the static linker.
2690 The linker cannot copy them because we do not specify a .size for the
2691 _closure entries (in the .data section) though in principle we could.

2737 Following a suggestion of Claus Reinke, this patch improves the error
2738 messages involving type functions.  Here's the relevant note from TcTyFuns.
2739 
2740 Note [Non-injective type functions]
2741 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2742 It's very confusing to get a message like
2743      Couldn't match expected type `Depend s'
2744             against inferred type `Depend s1'
2745 so pp_open_tc adds:
2746        NB: `Depend' is a (non-injective) type function
2747 
2748 Currently we add this independently for each argument, so we also get
2749      Couldn't match expected type `a'
2750             against inferred type `Dual (Dual a)'
2751        NB: `Dual' is a (non-injective) type function
2752 which is arguably redundant.  But on the other hand, it's probably
2753 a good idea for the programmer to know the error involves type functions
2754 so I've left it in for now.  The obvious alternative is to only add
2755 this NB in the case of matching (T ...) ~ (T ...).

3020 - This patch changes the equality constraint solver such that it does not
3021   instantiate any type variables that occur in the constraints that are to be
3022   solved (or in the environment).  Instead, it returns a bag of type bindings.
3023 - If these type bindings (together with the other results of the solver) are
3024   discarded, solver invocation has no effect (outside the solver) and can be
3025   repeated (that's imported for TcSimplifyRestricted).
3026 - For the type bindings to take effect, the caller of the solver needs to
3027   execute them.
3028 - The solver will still instantiate type variables thet were created during
3029   solving (e.g., skolem flexibles used during type flattening).

3117Simon Marlow <marlowsd@gmail.com>**20090421131038
3118 Ignore-this: 15298691a63e13c63a68673202b1fc18
3119 
3120 In GHCi if you say 'import Foo' meaning to load a package module Foo,
3121 and Foo.hs is found on the search path, then GHCi replies "module Foo
3122 is not loaded", because it knows Foo refers to the source file rather
3123 than the package module, and you haven't loaded that module with
3124 :load.
3125 
3126 This is consistent with the usual module-finding semantics.  However,
3127 it isn't particularly useful.  And it leads to silly problems like not
3128 being able to start GHCi when you happen to be sitting in
3129 libraries/base, because GHCi thinks the Prelude hasn't been loaded.
3130 
3131 So now I've made a slight change to the way that 'import M' works: if
3132 M is loaded, then it refers to the loaded module, otherwise it looks
3133 for a package module M.  This does what the reporter of #2682 wanted,
3134 and since it turns an error condition into meaningful behaviour it
3135 can't break anything. 
3136 
3137 The only undesirable consequence is that 'import M' might refer to a
3138 different M than ':load M'.  Hopefully that won't lead to confusion.

3149Simon Marlow <marlowsd@gmail.com>**20090420142525
3150 Ignore-this: 8d1b2624a4635b421032463219af604e
3151 
3152 It turns out we can easily support breakpoints on expressions with
3153 unlifted types, by translating
3154 
3155   case tick# of _ -> e
3156 
3157 into
3158 
3159   let f = \s . case tick# of _ -> e
3160   in  f realWorld#
3161 
3162 instead of just a plain let-binding.  This is the same trick that GHC
3163 uses for abstracting join points of unlifted type.
3164 
3165 In #2845, GHC has eta-expanded the tick expression, changing the
3166 result type from IO a to (# State#, a #), which was the reason the
3167 tick was suddenly being ignored.  By supporting ticks on unlifted
3168 expressions we can make it work again, although some confusion might
3169 arise because _result will no longer be available (it now has
3170 unboxed-tuple type, so we can't bind it in the environment).  The
3171 underlying problem here is that GHC does transformations like
3172 eta-expanding the tick expressions, and there's nothing we can do to
3173 prevent that.

3215David Waern <david.waern@gmail.com>**20090417145855
3216 
3217 Simon P-J suggested the following simplifications in #3097:
3218 
3219 * Allow nested foralls in `ctype` just like in `ctypedoc`.
3220 * Use `gentype` rather than `type` in the LHS of type declarations.
3221 * Inline `type` in `ctype`.
3222 * Rename `gentype` to `type`.
3223 
3224 This patch does this. Also, the equivalent thing is done for documented types.

3380 This patch is the result of a long series of nofib-based experiments
3381 to improve GHC's inlining heuristics.
3382 
3383 In the end, I'm not sure how worthwhile it all was: I only got a
3384    1% decrease in code size
3385    1% decrease in allocation
3386 and I don't trust the runtime statistics enough to quote.
3387 
3388 Still, in doing all this I tidied up the code quite a bit, and
3389 I understand it much better now, so I'm going to commit it.

3396   - the default unfolding threshold (in StaticFlags)

3525 
3526 We now use `ctypedoc` instead of `ctype` for type synonyms. `ctypedoc` was
3527 previously only used for top-level type signatures. This change means that type
3528 synonyms now can contain comments, just like top-level type signatures.
3529   
3530 Note:
3531   
3532 * I've modified `ctypedoc` so it allows implicit parameters and equational
3533 constraints, just like ctype.
3534   
3535 * Since `ctypedoc` allows nested foralls, we now allow that in type synonyms.
3536   
3537 * I have inlined some productions into gentypedoc so that there is now a
3538 non-doc version of every production with a 'doc' suffix. (Stylistic change
3539 only, which should make the code easier to follow).
3540   
3541 * It would have been nice to simplify the grammar by unifying `ctype` and
3542 ctypedoc` into one production, allowing comments on types everywhere (and
3543 rejecting them after parsing, where necessary).  This is however not possible
3544 since it leads to ambiguity. The reason is the support for comments on record
3545 fields:
3546   
3547 > data R = R { field :: Int -- ^ comment on the field }
3548   
3549 If we allow comments on types here, it's not clear if the comment applies
3550 to 'field' or to 'Int'. So we must use `ctype` to describe the type.

3574 a black hole, by changing the order of patterm matching in
3575 TyCon.isProductTyCon!  It turned out that GHC had been avoiding the
3576 black hole only by the narrowest of margins up to now!
3577 
3578 The black hole concerned the computation of which type constructors
3579 are recursive, in TcTyDecls.calcRecFlags.  We now refrain from using
3580 isProductTyCon there, since it triggers the black hole (very
3581 indirectly).  See the "YUK YUK" comment in the body of calcRecFlags.
3582 
3583 As it turns out, the fact that TyCon.isProductTyCon matched on the
3584 algTcRec field was quite redundant, so I removed that too.  However,
3585 without the fix to calcRecFlags, this wouldn't fix the black hole
3586 because of the use of isRecursiveTyCon in BuildTyCl.mkNewTyConRhs.
3587 
3588 Anyway, it's fine now.

3602 
3603 While I was looking at the desugaring of pattern matching (fixing
3604 Trac #3126) I finally got around to fixing another long-standing bug:
3605 when matching in a record pattern, GHC should match left-to-right in
3606 the programmer-specfied order, *not* left-to-right positionally in
3607 the original record declaration.
3608 
3609 Needless to say, that requires a little more code.

3618 Claus Reinke uncovered a long-standing bug in GHC, whereby we were
3619 combining the pattern-match on overloaded literals, missing the fact
3620 that an intervening pattern (for a different literal) might also
3621 match.  (If someone had a very odd implementation of fromInteger!)
3622 
3623 See Note [Grouping overloaded literal patterns] in Match.lhs

3791 Ignore-this: 9249b00a2292563e68d5d715376b216c
3792 
3793 This patch adds an optional CONLIKE modifier to INLINE/NOINLINE pragmas,
3794    {-# NOINLINE CONLIKE [1] f #-}
3795 The effect is to allow applications of 'f' to be expanded in a potential
3796 rule match.  Example
3797   {-# RULE "r/f" forall v. r (f v) = f (v+1) #-}
3798 
3799 Consider the term
3800      let x = f v in ..x...x...(r x)...
3801 Normally the (r x) would not match the rule, because GHC would be scared
3802 about duplicating the redex (f v). However the CONLIKE modifier says to
3803 treat 'f' like a constructor in this situation, and "look through" the
3804 unfolding for x.  So (r x) fires, yielding (f (v+1)).
3805 
3806 The main changes are:
3807   - Syntax
3808 
3809   - The inlinePragInfo field of an IdInfo has a RuleMatchInfo
3810     component, which records whether or not the Id is CONLIKE.
3811     Of course, this needs to be serialised in interface files too.
3812 
3813   - The occurrence analyser (OccAnal) and simplifier (Simplify) treat
3814     CONLIKE thing like constructors, by ANF-ing them
3815 
3816   - New function coreUtils.exprIsExpandable is like exprIsCheap, but
3817     additionally spots applications of CONLIKE functions
3818 
3819   - A CoreUnfolding has a field that caches exprIsExpandable
3820 
3821   - The rule matcher consults this field.  See
3822     Note [Expanding variables] in Rules.lhs.
3823 
3824 On the way I fixed a lurking variable bug in the way variables are
3825 expanded.  See Note [Do not expand locally-bound variables] in
3826 Rule.lhs.  I also did a bit of reformatting and refactoring in
3827 Rules.lhs, so the module has more lines changed than are really
3828 different.

3839 Generate binary log files from the RTS containing a log of runtime
3840 events with timestamps.  The log file can be visualised in various
3841 ways, for investigating runtime behaviour and debugging performance
3842 problems.  See for example the forthcoming ThreadScope viewer.
3843 
3844 New GHC option:
3845 
3846   -eventlog   (link-time option) Enables event logging.
3847 
3848   +RTS -l     (runtime option) Generates <prog>.eventlog with
3849               the binary event information.
3850 
3851 This replaces some of the tracing machinery we already had in the RTS:
3852 e.g. +RTS -vg  for GC tracing (we should do this using the new event
3853 logging instead).
3854 
3855 Event logging has almost no runtime cost when it isn't enabled, though
3856 in the future we might add more fine-grained events and this might
3857 change; hence having a link-time option and compiling a separate
3858 version of the RTS for event logging.  There's a small runtime cost
3859 for enabling event-logging, for most programs it shouldn't make much
3860 difference.

3951 load-balancing altogether, which turns out to be important in parallel
3952 programs.  Maintaining locality is sometimes more important that
3953 spreading the work out in parallel GC.  There is a side benefit in
3954 that the parallel GC should have improved locality even when
3955 load-balancing, because each processor prefers to take work from its
3956 own queue before stealing from others.

3958[Fix Trac #3087: derived Data now defines dataCast1/2
3959simonpj@microsoft.com**20090313134436

3961 
3962 This patch generates code in deriving(Data) for dataCast1 or 2 as
3963 appropriate.
3964 
3965 While I was there I did some refactoring (of course), pulling out
3966 the TcDeriv.inferConstraints as a separate function.
3967 
3968 I don't think it's worth merging this to 6.10.2, even though it's a bugfix,
3969 because it modifies code that I added in the HEAD only (for deriving Functor)
3970 so the merge will be sligtly awkward.  And there's an easy workaround.

3992 This reduces the latency between a context-switch being triggered and
3993 the thread returning to the scheduler, which in turn should reduce the
3994 cost of the GC barrier when there are many cores.
3995 
3996 We still retain the old context_switch flag which is checked at the
3997 end of each block of allocation.  The idea is that setting HpLim may
3998 fail if the the target thread is modifying HpLim at the same time; the
3999 context_switch flag is a fallback.  It also allows us to "context
4000 switch soon" without forcing an immediate switch, which can be costly.
