22Manuel M T Chakravarty <[email protected]>**20080526073546
23 - When compiling with -mmacos-deployment-target=10.4, we need
24   --no-builtin-fprintf, as the use of GCC's builtin function
25   optimisation for fprintf together with #include "PosixSource" in the
26   RTS leads to the use of fwrite$UNIX2003 (with GCC 4.0.1 on Mac OS X
27   10.5.2).

46[Fix Trac #1061: refactor handling of default methods
47[email protected]**20080521130028
48 
49 In an instance declaration, omitted methods get a definition that
50 uses the default method.  We used to generate source code and feed it
51 to the type checker.  But tc199 shows that is a bad idea -- see
52 Note [Default methods in instances] in TcClassDcl.
53 
54 So this patch refactors to insteadl all us to generate the
55 *post* typechecked code directly for default methods.

139Simon Marlow <[email protected]>**20080516130045
140 On a 2.6.24 Linux kernel, it appears that timer_settime() for
141 CLOCK_REALTIME is sometimes hanging for a random amount of time when
142 given a very small interval (we were using 1ns).  Using 1ms seems to
143 be fine.  Also I installed a 1-second timeout to catch hangs in the
144 future.

165[Improve the treatment of 'seq' (Trac #2273)
166[email protected]**20080516085149
167 
168 Trac #2273 showed a case in which 'seq' didn't cure the space leak
169 it was supposed to.  This patch does two things to help
170 
171 a) It removes a now-redundant special case in Simplify, which
172    switched off the case-binder-swap in the early stages.  This
173    isn't necessary any more because FloatOut has improved since
174    the Simplify code was written.  And switching off the binder-swap
175    is harmful for seq.
176 
177 However fix (a) is a bit fragile, so I did (b) too:
178 
179 b) Desugar 'seq' specially.  See Note [Desugaring seq (2)] in DsUtils
180    This isn't very robust either, since it's defeated by abstraction,
181    but that's not something GHC can fix; the programmer should use
182    a let! instead.

221 This turned out not to be too hard, just a matter of figuring out the

253[Fixes to via-C prototype generation (FIX BUILD on Windows)
254Simon Marlow <[email protected]>**20080512110643
255   
256 Previously we declared all external labels with type StgWord[],
257 because the same label might be used at different types in the same
258 file, e.g. if there are multiple foreign import declarations for the
259 same function.  However, we have to declare called functions with the
260 right type on Windows, because this is the only way to make the
261 compiler add the appropriate '@n' suffix for stdcall functions.
262 
263 Related to this is the reason we were getting mangler complaints
264 (epilogue mangling) when compiling the RTS with -fvia-C.  The function
265 barf() doesn't return, but we had lost that information by declaring
266 our own prototypes, and so gcc was generating extra code after the
267 call to barf().

338[email protected]**20080506102551
339 
340 The real work of fixing Trac #2246 is to use shortCutLit in
341 MatchLit.dsOverLit, so that type information discovered late in the
342 day by the type checker can still be exploited during desugaring.
343 
344 However, as usual I found myself doing some refactoring along the
345 way, to tidy up the handling of overloaded literals.   The main
346 change is to split HsOverLit into a record, which in turn uses
347 a sum type for the three variants.  This makes the code significantly
348 more modular.
349 
350 data HsOverLit id
351   = OverLit {
352        ol_val :: OverLitVal,
353        ol_rebindable :: Bool,          -- True <=> rebindable syntax
354                                        -- False <=> standard syntax
355        ol_witness :: SyntaxExpr id,    -- Note [Overloaded literal witnesses]
356        ol_type :: PostTcType }

495Tim Chevalier <chevalier@alum.wellesley.edu>**20080504024304
496 
497 Add new syntax in External Core for primitive coercions (trans,
498 sym, etc.) rather than wiring their names into the ext-core
499 parser.

501[Fix External Core interpreter
502Tim Chevalier <chevalier@alum.wellesley.edu>**20080503231044
503 
504 The External Core interpreter works (in a limited sense).
505 For details, see the README.
506 
507 This means we now have a marginally functioning set of
508 External Core tools.
509 
510 The other exciting change is that the test driver (Driver.hs)
511 now computes module dependencies automatically instead of
512 having a wired-in list of library modules.

519 has 'kinds'.  Renamed type constructor, data constructor, and record

522[new version of ZipDataflow
523Norman Ramsey <nr@eecs.harvard.edu>**20080503224208
524 This version combines forward/backard into a type class
525 (actually two classes) of analysis and transformation.
526 These type classes will always be expanded away at the client,
527 so SLPJ may wonder why they exist: it is because the interface
528 to this module is already very broad, and by overloading the functions
529 for forward and backward problems, we cut the cognitive load on the
530 clients in half.

535 and names.  Also eliminated some warnings.  This patch covers
536 most (but not all) of the code NR changed at the very end
537 of September 2007, just before ICFP hit...

544 `pwd`/inst probably won't give a useful value on all platforms (in

590simonpj@microsoft.com**20080428155711

592 The specialiser was using a rather brain-dead representation for
593 UsageDetails, with much converting from lists to finite maps and
594 back.  This patch does some significant refactoring.  It doesn't
595 change the representation altogether, but it does eliminate the
596 to-and-fro nonsense.
597 
598 It validates OK, but it's always possible that I have inadvertently

981[Simplify SimplCont, plus some other small changes to the Simplifier
982simonpj@microsoft.com**20080422120400
983 
984 The main change in this patch is this:
985   
986   * The Stop constructor of SimplCont no longer contains the OutType
987     of the whole continuation.  This is a nice simplification in
988     lots of places where we build a Stop continuation.  For example,
989     rebuildCall no longer needs to maintain the type of the function.
990 
991   * Similarly StrictArg no longer needs an OutType
992 
993   * The consequential complication is that contResultType (not called
994     much) needs to be given the type of the thing in the middle.  No
995     big deal.
996 
997   * Lots of other small knock-on effects
998 
999 Other changes in here
1000 
1001   * simplLazyBind does do the type-abstraction thing if there's
1002     a lambda inside.  See comments in simplLazyBind
1003 
1004   * simplLazyBind reduces simplifier iterations by keeping
1005     unfolding information for stuff for which type abstraction is
1006     done (see add_poly_bind)
1007 
1008 All of this came up when implementing System IF, but seems worth applying
1009 to the HEAD

1017simonpj@microsoft.com**20080422115238
1018 
1019 In SpecConstr.isValue, we recorded a ConVal for a big-lambda,
1020 which seems wrong. I came across this when implementing System IF.
1021 The code now reads:
1022 
1023   isValue env (Lam b e)
1024     | isTyVar b = case isValue env e of
1025                    Just _  -> Just LambdaVal   -- NB!
1026                    Nothing -> Nothing
1027     | otherwise = Just LambdaVal

1032[Fix a long-standing bug in FloatOut
1033simonpj@microsoft.com**20080422115003
1034 
1035 We really should not float anything out of an _inline_me_ Note,
1036 for reasons described in this new comment:
1037        -- Do no floating at all inside INLINE.
1038        -- The SetLevels pass did not clone the bindings, so it's
1039        -- unsafe to do any floating, even if we dump the results
1040        -- inside the Note (which is what we used to do).
1041 
1042 I'm about to get rid of these _inline_me_ Notes, but it's
1043 better to fix it anyway.  I found this bug when implementing System IF.

1071Tim Chevalier <chevalier@alum.wellesley.edu>**20080422015622
1072 
1073 Reorganized coercion-related code in the typechecker (this was
1074 brought about by typechecking the Core versions of the optimized GHC
1075 libraries.) A few miscellaneous changes (fixed a bug in Prep involving
1076 eta-expanding partial applications that had additional type
1077 arguments.)

1079[Naming changes in External Core
1080Tim Chevalier <chevalier@alum.wellesley.edu>**20080422012734
1081 
1082 Two changes:
1083 - Top-level bindings in a given module are now printed as a
1084   single %rec group. I found that in External Core generated from
1085   optimized code, nonrec bindings weren't being printed in
1086   dependency order. Rather than fixing that, I decided to not
1087   even pretend to preserve dependency order (since there's
1088   recursion between modules anyway.)
1089 
1090 - Internal names are now printed with their uniques attached
1091   (otherwise, GHC was printing out code with shadowed bindings,
1092   and this isn't supposed to happen in External Core.)

1200 
1201 See Note [exprArity invariant] in CoreUtils.  In code generated by Happy
1202 I was seeing this after TidyPgm and CorePrep
1203 
1204        f :: Any
1205        f {arity 1} = id `cast` unsafe-co
1206 
1207 So f claimed to have arity 1 (because exprArity looked inside), but
1208 did not have any top-level lambdas (because its type is Any). 
1209 
1210 This triggered a slightly-obscure ASSERT failure in CoreToStg
1211 
1212 This patch
1213        - makes exprArity trim the arity if the type is not a function

1261Simon Marlow <simonmar@microsoft.com>**20080408183434
1262 
1263 This replaces the hand-rolled architecture-specific FFI support in
1264 GHCi with the standard libffi as used in GCJ, Python and other
1265 projects.  I've bundled the complete libffi-3.0.4 tarball in the
1266 source tree in the same way as we do for GMP, the difference being
1267 that we always build and install our own libffi regardless of whether
1268 there's one on the system (it's small, and we don't want
1269 dependency/versioning headaches).
1270 
1271 In particular this means that unregisterised builds will now have a
1272 fully working GHCi including FFI out of the box, provided libffi
1273 supports the platform.
1274 
1275 There is also code in the RTS to use libffi in place of
1276 rts/Adjustor.c, but it is currently not enabled if we already have
1277 support in Adjustor.c for the current platform.  We need to assess the
1278 performance impact before using libffi here too (in GHCi we don't care
1279 too much about performance).

1326simonpj@microsoft.com**20080404205556
1327 
1328 This patch fixes a rather tiresome issue, namely the fact that
1329 a TH declaration quote *shadows* bindings in outer scopes:
1330 
1331   f g = [d| f :: Int
1332             f = g
1333            g :: Int
1334             g = 4 |]
1335 
1336 Here, the outer bindings for 'f' (top-level) and 'g' (local)
1337 are shadowed, and the inner bindings for f,g should not be
1338 reported as duplicates.  (Remember they are top-level bindings.)
1339 
1340 The actual bug was that we'd forgotten to delete 'g' from the
1341 LocalRdrEnv, so the type sig for 'g' was binding to the outer
1342 'g' not the inner one.

1387Simon Marlow <simonmar@microsoft.com>**20080402051412
1388 
1389 This has several advantages:
1390 
1391  - -fvia-C is consistent with -fasm with respect to FFI declarations:
1392    both bind to the ABI, not the API.
1393 
1394  - foreign calls can now be inlined freely across module boundaries, since
1395    a header file is not required when compiling the call.
1396 
1397  - bootstrapping via C will be more reliable, because this difference
1398    in behavour between the two backends has been removed.
1399 
1400 There is one disadvantage:
1401 
1402  - we get no checking by the C compiler that the FFI declaration
1403    is correct.
1404 
1405 So now, the c-includes field in a .cabal file is always ignored by
1406 GHC, as are header files specified in an FFI declaration.  This was
1407 previously the case only for -fasm compilations, now it is also the
1408 case for -fvia-C too.

1426     letter that could be a hex digit, aren't handled properly. I'm
1427     investigating whether this is a bug in Parsec or expected behavior.

1523[Print out rational literals correctly in External Core
1524Tim Chevalier <chevalier@alum.wellesley.edu>**20080328211919
1525 
1526 The External Core printer was printing out rational literals of the
1527 form:
1528 2.0e-2
1529 when the External Core grammar doesn't allow this. (This
1530 bug has apparently been there since the beginning...)
1531 
1532 It's now printing rationals in the same form that (show (r::Rational))
1533 does. This requires a parser change as well (soon to come.)

1543 from an unqualified name:
1544    a
1545 
1546 - z-encode package names ("ghc-prim" was the culprit.)

1586[Change syntax for newtypes in External Core
1587Tim Chevalier <chevalier@alum.wellesley.edu>**20080325170218
1588 
1589 The way that newtype declarations were printed in External Core files was
1590 incomplete, since there was no declaration for the coercion introduced by a
1591 newtype.
1592 
1593 For example, the Haskell source:
1594 
1595 newtype T a = MkT (a -> a)
1596 
1597 foo (MkT x) = x
1598 
1599 got printed out in External Core as (roughly):
1600 
1601   %newtype T a = a -> a;
1602 
1603   foo :: %forall t . T t -> t -> t =
1604     %cast (\ @ t -> a1 @ t)
1605     (%forall t . T t -> ZCCoT t);
1606 
1607 There is no declaration anywhere in the External Core program for :CoT, so
1608 that's bad.
1609 
1610 I changed the newtype decl syntax so as to include the declaration for the
1611 coercion axiom introduced by the newtype. Now, it looks like:
1612 
1613   %newtype T a ^ (ZCCoT :: ((T a) :=: (a -> a))) = a -> a;
1614 
1615 And an external typechecker could conceivably typecheck code that uses this.
1616 
1617 The major changes are to MkExternalCore and PprExternalCore (as well as
1618 ExternalCore, to change the External Core AST.) I also corrected some typos in
1619 comments in other files.
1620

1655[Handle hierarchical module names in External Core tools
1656Tim Chevalier <chevalier@alum.wellesley.edu>**20080320014449
1657 
1658 I updated the parser to handle hierarchical module names (with package names)
1659 the way GHC is currently printing them out in External Core.
1660 
1661 Beware kludgy use of z-encoding and gratutious copy-pasta from GHC.
1662 
1663 You can now use the stand-alone Core parser to parse a very simple
1664 GHC-generated .hcr file (progress!) but not to typecheck or interpret it
1665 (the typechecker/interpreter don't snarf in the right libraries yet, among
1666 other things.) And, the parser is still incomplete in that it doesn't handle
1667 programs with newtypes/GADTs/etc. whose syntax has changed since 2003. In
1668 other words: probably don't try to use this yet.
1669 
1670]
1671[Improve hierarchical module name handling in MkExternalCore
1672Tim Chevalier <chevalier@alum.wellesley.edu>**20080319190429
1673 
1674 It's easier for the External Core parser if MkExternalCore prints
1675 module names like:
1676    base:GHCziBase
1677 rather than like:
1678    base:GHC.Base
1679 (which it was doing before.)
1680 
1681 So now we z-encode the hierarchical module-name part of a module
1682 name, but don't z-encode the ':'.
1683 
1684 I also removed some old comments that don't seem relevant anymore.

1689 There was a (suppressed) warning about an incomplete pattern match in make_alt. This was because the DEFAULT alt never has variable bindings. I thought it would be better to check that case and panic if it happens than to have an incomplete pattern. It's still not great, but at least now we don't have to suppress any warnings in this file.

1816                  :DEq eq neq -> eq x x
1817 
1818 But because of the -O the $f20 dictionary is not available, so exposing
1819 the dictionary selector was useless.  Yet it makes the code bigger!
1820 Better to get

1823 This patch suppresses the implicit unfolding for dictionary selectors

1825 Ids, but this will do for now.
1826 
1827 There should be no effect when compiling with -O.  Programs should

1849simonpj@microsoft.com**20080306120004
1850 
1851 This patch makes a significant improvement to SpecConstr, based on
1852 Roman's experience with using it for stream fusion.  The main change is
1853 this:
1854 
1855   * For local (not-top-level) declarations, seed the specialisation
1856     loop from the calls in the body of the 'let'.
1857 
1858 See Note [Local recursive groups] for discussion and example.  Top-level
1859 declarations are treated just as before.
1860 
1861 Other changes in this patch:
1862 
1863   * New flag -fspec-constr-count=N sets the maximum number of specialisations
1864     for any single function to N.  -fno-spec-constr-count removes the limit.
1865 
1866   * Refactoring in specLoop and friends; new algebraic data types
1867     OneSpec and SpecInfo instead of the tuples that were there before
1868 
1869   * Be less keen to specialise on variables that are simply in scope.
1870     Example
1871       f p q = letrec g a y = ...g....  in g q p
1872     We probably do not want to specialise 'g' for calls with exactly
1873     the arguments 'q' and 'p', since we know nothing about them.

1936[Fix Trac #2130: improve derived Ord for primmitive types
1937simonpj@microsoft.com**20080228121106
1938 
1939 This patch does two things:
1940 
1941 * (Minor): in TcGenDeriv.careful_compare_Case, test for less-than before
1942   equality. This should reduce the number of dynamic tests, and also gives
1943   more scope for optimisation, since less-than tells us more than equality.
1944 
1945 * (More important): add special-case derived code for data types that are
1946   simple wrappers of primitive types. See
1947        Note [Comparision of primitive types]
1948   This fixes Trac 2130.
1949 
1950 However see also Trac #2132, which is not addressed here.

1958Simon Marlow <simonmar@microsoft.com>**20080228111631
1959 It turns out that -prof -threaded works (modulo some small changes),
1960 because all the data structures used in profiling are only accessed by
1961 one thread at a time, at long as we don't use +RTS -N2 or higher.  So
1962 this patch enables the use of -prof -threaded, but an error is given

1973 - A while ago, I changed the type checker to use equality constraints together
1974   with implication constraints to track local type refinement due to GADT

1976   to remove the resulting dead code of the previous GADT refinement machinery.

2106[All installed Haskell prgms have an inplace and an installed version
2107Manuel M T Chakravarty <chak@cse.unsw.edu.au>**20080218061809
2108 - GHC installs a range of compiled Haskell programs in addition to the actual
2109   compiler.  To ensure that they all run on the platform targeted by the build
2110   (which may have different libraries installed than the build host), we need
2111   to make sure that all compiled Haskell code going into an install is build
2112   with the stage 1 compiler, not the bootstrap compiler.  Getting this right
2113   is especially important on the Mac to enable builds that work on Mac OS X
2114   versions that are older than the one performing the build.
2115 - For all installed utils implemented in Haskell (i.e., ghc-pkg, hasktags,
2116   hsc2hs, runghc, hpc, and pwd) we compile two versions, an inplace version
2117   and a version for installation.  The former is build by the bootstrap
2118   compiler during the stage 1 build and the latter is build by the stage 1
2119   compiler during the stage 2 build.
2120 - This is really very much as the setup for ghc itself, only that we don't use
2121   separate stage1/ and stage2/ build directories.  Instead, we clean before
2122   each build.  CAVEAT: This only works properly if invoked from the
2123   toplevel Makefile.
2124 - Instead of UseStage1=YES (as used by the previous binary-dist-specific
2125   recompilation), we now use the same $(stage) variables as used for the
2126   compiler proper - to increase uniformity and to avoid extra conditionals for
2127   the install target.

2235 Every simplifier phase can have an arbitrary number of tags and multiple
2236 phases can share the same tags. The tags can be used as arguments to
2237 -ddump-simpl-phases to specify which phases are to be dumped.
2238 For instance, -ddump-simpl-phases=main will dump the output of phases 2, 1 and
2239 0 of the initial simplifier run (they all share the "main" tag) while
2240 -ddump-simpl-phases=main:0 will dump only the output of phase 0 of that run.
2241 
2242 At the moment, the supported tags are:
2243 
2244   main                 The main, staged simplifier run (before strictness)
2245   post-worker-wrapper  After the w/w split
2246   post-liberate-case   After LiberateCase

2299 
2300 This adds back in the patch
2301   * UNDO: Be a little keener to inline
2302 
2303 It originally broke the compiler because it tickled a Cmm optimisation bug,
2304 now fixed. 
2305 
2306 In revisiting this I have also make inlining a bit cleverer, in response to
2307 more examples from Roman. In particular
2308 
2309   * CoreUnfold.CallCtxt is a data type that tells something about
2310     the context of a call.  The new feature is that if the context is
2311     the argument position of a function call, we record both
2312        - whether the function (or some higher up function) has rules
2313        - what the argument discount in that position is
2314     Either of these make functions keener to inline, even if it's
2315     in a lazy position
2316 
2317   * There was conseqential tidying up on the data type of CallCont.
2318     In particular I got rid of the now-unused LetRhsFlag

2371[Teach cheapEqExpr about casts
2372Roman Leshchinskiy <rl@cse.unsw.edu.au>**20080206035007
2373 
2374 Previously, cheapEqExpr would always return False if it encountered a cast.
2375 This was bad for two reasons. Firstly, CSE (which uses cheapEqExpr to compare
2376 expressions) never eliminated expressions which contained casts and secondly,
2377 it was inconsistent with exprIsBig. This patch fixes this.

2379[Inject implicit bindings before the simplifier (Trac #2070)
2380simonpj@microsoft.com**20080205165507
2381 
2382 With constructor unpacking, it's possible for constructors and record
2383 selectors to have non-trivial code, which should be optimised before
2384 being fed to the code generator.  Example:
2385 
2386   data Foo = Foo { get :: {-# UNPACK #-} !Int }
2387 
2388 Then we do not want to get this:
2389   T2070.get =
2390     \ (tpl_B1 :: T2070.Foo) ->
2391     case tpl_B1 of tpl1_B2 { T2070.Foo rb_B4 ->
2392         let {
2393           ipv_B3 [Just S] :: GHC.Base.Int
2394           [Str: DmdType m]
2395           ipv_B3 = GHC.Base.I# rb_B4
2396         } in  ipv_B3 }
2397 
2398 If this goes through to codegen, we'll generate bad code.  Admittedly,
2399 this only matters when the selector is used in a curried way (e.g
2400 map get xs), but nevertheless it's silly.
2401 
2402 This patch injects the implicit bindings in SimplCore, before the
2403 simplifier runs.  That slows the simplifier a little, because it has
2404 to look at some extra bindings; but it's probably a slight effect.
2405 If it turns out to matter I suppose we can always inject them later,
2406 e.g. just before the final simplification.
2407 
2408 An unexpected (to me) consequence is that we get some specialisation rules
2409 for class-method selectors.  E.g. we get a rule
2410        RULE  (==) Int dInt = eqInt
2411 There's no harm in this, but not much benefit either, because the
2412 same result will happen when we inline (==) and dInt, but it's perhaps
2413 more direct.

2417[Make do-notation a bit more flexible (Trac #1537)
2418simonpj@microsoft.com**20080205164816
2419 
2420 This is a second attempt to fix #1537: to make the static typechecking
2421 of do-notation behave just like the desugared version of the same thing.
2422 This should allow parameterised monads to work properly (see Oleg's comment
2423 in the above ticket).
2424 
2425 We can probably merge to 6.8.3 if it goes smoothly.
2426 
2427 Incidentally, the resulting setup suffers from greater type ambiguity
2428 if (>>=) has a very general type.  So test rebindable6 no longer works
2429 (at least not without more type signatures), and rebindable5 requires
2430 extra functional dependencies.  But they are weird tests.

2436Simon Marlow <simonmar@microsoft.com>**20080205101425
2437 Perhaps in the past '.align 2' meant align to 4 bytes, but nowadays it
2438 means align to 2 bytes.  The compacting collector requires info tables
2439 to be aligned to 4 bytes, because it stores tag bits in the low 2
2440 bits.
2441 
2442 This only affects -fvia-C - the native code generator was already
2443 emitting the correct alignment.  The incorrect alignment might well
2444 have been adversely affecting performance with -fvia-C on Windows.

2857[Attach the INLINE Activation pragma to any automatically-generated specialisations
2858simonpj@microsoft.com**20080123134012
2859 
2860 Another idea suggested by Roman, happily involving a one-line change.  Here's
2861 the new Note in Specialise:
2862 
2863 Note [Auto-specialisation and RULES]
2864 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2865 Consider:
2866    g :: Num a => a -> a
2867    g = ...
2868 
2869    f :: (Int -> Int) -> Int
2870    f w = ...
2871    {-# RULE f g = 0 #-}
2872 
2873 Suppose that auto-specialisation makes a specialised version of
2874 g::Int->Int That version won't appear in the LHS of the RULE for f.
2875 So if the specialisation rule fires too early, the rule for f may
2876 never fire.
2877 
2878 It might be possible to add new rules, to "complete" the rewrite system.
2879 Thus when adding
2880        RULE forall d. g Int d = g_spec
2881 also add
2882        RULE f g_spec = 0
2883 
2884 But that's a bit complicated.  For now we ask the programmer's help,
2885 by *copying the INLINE activation pragma* to the auto-specialised rule.
2886 So if g says {-# NOINLINE[2] g #-}, then the auto-spec rule will also
2887 not be active until phase 2.
2888 
2889]
2890[Tidy up the treatment of SPECIALISE pragmas
2891simonpj@microsoft.com**20080122122613
2892 
2893 Remove the now-redundant "const-dicts" field in SpecPrag
2894 
2895 In dsBinds, abstract over constant dictionaries in the RULE.
2896 This avoids the creation of a redundant, duplicate, rule later
2897 in the Specialise pass, which was happening before.
2898 
2899 There should be no effect on performance either way, just less
2900 duplicated code, and the compiler gets a little simpler.

2938[FIX #1839, #1463, by supporting ghc-pkg bulk queries with substring matching
2939claus.reinke@talk21.com**20080121161744
2940 
2941    - #1839 asks for a ghc-pkg dump feature, #1463 for the ability
2942      to query the same fields in several packages at once.
2943 
2944    - this patch enables substring matching for packages in 'list',
2945      'describe', and 'field', and for modules in find-module. it
2946      also allows for comma-separated multiple fields in 'field'.
2947      substring matching can optionally ignore cases to avoid the
2948      rather unpredictable capitalisation of packages.
2949 
2950    - the patch is not quite as full-featured as the one attached
2951      to #1839, but avoids the additional dependency on regexps.
2952      open ended substrings are indicated by '*' (only the three
2953      forms prefix*, *suffix, *infix* are supported)
2954 
2955    - on windows, the use of '*' for package/module name globbing
2956      leads to conflicts with filename globbing: by default, windows
2957      programs are self-globbing, and bash adds another level of
2958      globbing on top of that. it seems impossible to escape '*'
2959      from both levels of globbing, so we disable default globbing
2960      for ghc-pkg and ghc-pkg-inplace. users of bash will still
2961      have filename globbing available, users of cmd won't.
2962 
2963    - if it is considered necessary to reenable filename globbing
2964      for cmd users, it should be done selectively, only for
2965      filename parameters. to this end, the patch includes a
2966      glob.hs program which simply echoes its parameters after
2967      filename globbing. see the commented out glob command in
2968      Main.hs for usage or testing.
2969 
2970    - this covers both tickets, and permits for the most common
2971      query patterns (finding all packages contributing to the
2972      System. hierarchy, finding all regex or string packages,
2973      listing all package maintainers or haddock directories,

2993Simon Marlow <simonmar@microsoft.com>**20080121145935
2994 The previous attempt to fix this (#1873, #1360) left a problem that
2995 occurred when the first :load of the program failed (#2049). 
2996 
2997 Now I've implemented a different strategy: between :loads, we remember
2998 all the :module commands, and just replay them after a :reload.  This
2999 is in addition to remembering all the package modules added with
3000 :module, which is orthogonal.
3001 
3002 This approach is simpler than the previous one, and seems to do the
3003 right thing in all the cases I could think of.  Let's hope this is the
3004 last bug in this series...

3109[Add quasi-quotation, courtesy of Geoffrey Mainland
3110simonpj@microsoft.com**20080118145503
3111 
3112 This patch adds quasi-quotation, as described in
3113   "Nice to be Quoted: Quasiquoting for Haskell"
3114        (Geoffrey Mainland, Haskell Workshop 2007)
3115 Implemented by Geoffrey and polished by Simon.
3116 
3117 Overview
3118 ~~~~~~~~
3119 The syntax for quasiquotation is very similar to the existing
3120 Template haskell syntax:
3121        [$q| stuff |]
3122 where 'q' is the "quoter".  This syntax differs from the paper, by using
3123 a '$' rather than ':', to avoid clashing with parallel array comprehensions.
3124 
3125 The "quoter" is a value of type Language.Haskell.TH.Quote.QuasiQuoter, which
3126 contains two functions for quoting expressions and patterns, respectively.
3127 
3128      quote = Language.Haskell.TH.Quote.QuasiQuoter quoteExp quotePat
3129 
3130      quoteExp :: String -> Language.Haskell.TH.ExpQ
3131      quotePat :: String -> Language.Haskell.TH.PatQ
3132 
3133 TEXT is passed unmodified to the quoter. The context of the
3134 quasiquotation statement determines which of the two quoters is
3135 called: if the quasiquotation occurs in an expression context,
3136 quoteExp is called, and if it occurs in a pattern context, quotePat
3137 is called.
3138 
3139 The result of running the quoter on its arguments is spliced into
3140 the program using Template Haskell's existing mechanisms for
3141 splicing in code. Note that although Template Haskell does not
3142 support pattern brackets, with this patch binding occurrences of
3143 variables in patterns are supported. Quoters must also obey the same
3144 stage restrictions as Template Haskell; in particular, in this
3145 example quote may not be defined in the module where it is used as a
3146 quasiquoter, but must be imported from another module.
3147 
3148 Points to notice
3149 ~~~~~~~~~~~~~~~~
3150 * The whole thing is enabled with the flag -XQuasiQuotes
3151 
3152 * There is an accompanying patch to the template-haskell library. This
3153   involves one interface change:
3154        currentModule :: Q String
3155   is replaced by
3156        location :: Q Loc
3157   where Loc is a data type defined in TH.Syntax thus:
3158       data Loc
3159         = Loc { loc_filename :: String
3160              , loc_package  :: String
3161              , loc_module   :: String
3162              , loc_start    :: CharPos
3163              , loc_end      :: CharPos }
3164 
3165       type CharPos = (Int, Int)        -- Line and character position
3166 
3167   So you get a lot more info from 'location' than from 'currentModule'.
3168   The location you get is the location of the splice.
3169   
3170   This works in Template Haskell too of course, and lets a TH program
3171   generate much better error messages.
3172 
3173 * There's also a new module in the template-haskell package called
3174   Language.Haskell.TH.Quote, which contains support code for the
3175   quasi-quoting feature.
3176 
3177 * Quasi-quote splices are run *in the renamer* because they can build
3178   *patterns* and hence the renamer needs to see the output of running the
3179   splice.  This involved a bit of rejigging in the renamer, especially
3180   concerning the reporting of duplicate or shadowed names.
3181 
3182   (In fact I found and removed a few calls to checkDupNames in RnSource
3183   that are redundant, becuase top-level duplicate decls are handled in
3184   RnNames.)

3236[Add -fspec-inline-join-points to SpecConstr
3237simonpj@microsoft.com**20080117150325
3238 
3239 This patch addresses a problem that Roman found in SpecConstr.  Consider:
3240 
3241 foo :: Maybe Int -> Maybe Int -> Int
3242 foo a b = let j b = foo a b
3243            in
3244            case b of
3245              Nothing -> ...
3246              Just n  -> case a of
3247                           Just m  -> ... j (Just (n+1)) ...
3248                           Nothing -> ... j (Just (n-1)) ...
3249 
3250 We want to make specialised versions for 'foo' for the patterns
3251        Nothing  (Just v)
3252        (Just a) (Just b)
3253 
3254 Two problems, caused by the join point j.  First, j does not
3255 scrutinise b, so j won't be specialised f for the (Just v) pattern.
3256 Second, j is defined where the free var 'a' is not evaluated.
3257 
3258 Both are solved by brutally inlining j at its call sites.  This risks
3259 major code bloat, but it's relatively quick to implement.  The flag
3260        -fspec-inline-join-points
3261 causes brutal inlining for a
3262        non-recursive binding
3263        of a function
3264        whose RHS contains calls
3265        of a recursive function
3266 
3267 The (experimental) flag is static for now, and I have not even
3268 documented it properly.

3346 
3347 The core type-matcher Unify.match was previouly using tcView to expand
3348 types, because it must treat newtypes as distinct from their representation.
3349 But that meant that it also treated the PredType {C Int} as distinct from
3350 its representation type (:TC Int).  And that in turn was causing a rule
3351 not to fire, because the argument types didn't match up.

3354 
3355   a = :DC blah blah    -- Dictionary
3356   ....(f a).....

3659simonpj@microsoft.com**20071221090406
3660 
3661 In a few places we want to "look through" newtypes to get to the
3662 representation type.  But we need to be careful that  we don't fall
3663 into an ininite loop with e.g.
3664        newtype T = MkT T
3665 
3666 The old mechansim for doing this was to have a field nt_rep, inside
3667 a newtype TyCon, that gave the "ultimate representation" of the type.
3668 But that failed for Trac 1495, which looked like this:
3669    newtype Fix a = Fix (a (Fix a))
3670    data I a = I a
3671 Then, expanding the type (Fix I) went on for ever.
3672 
3673 The right thing to do seems to be to check for loops when epxanding
3674 the *type*, rather than in the *tycon*.  This patch does that,
3675        - Removes nt_rep from TyCon
3676        - Make Type.repType check for loops
3677 See Note [Expanding newtypes] in Type.lhs.
3678 
3679 At the same time I also fixed a bug for Roman, where newtypes were not
3680 being expanded properly in FamInstEnv.topNormaliseType.  This function
3681 and Type.repType share a common structure.

4001 the ModuleName.  usg_name is the ModuleName.  Since Version is also an

4003 lookups in the map never succeeded.  I shall rename the fields of

4079simonpj@microsoft.com**20071203150039
4080 
4081 I finally got around to investigating why the Simplifier was sometimes
4082 iterating so often.  There's a nice example in Text.ParserCombinators.ReadPrec,
4083 which produced:
4084 
4085 NOTE: Simplifier still going after 3 iterations; bailing out.  Size = 339
4086 NOTE: Simplifier still going after 3 iterations; bailing out.  Size = 339
4087 NOTE: Simplifier still going after 3 iterations; bailing out.  Size = 339
4088 
4089 No progress is being made.  It turned out that an interaction between
4090 eta-expansion, casts, and eta reduction was responsible. The change is
4091 small and simple, in SimplUtils.mkLam: do not require the body to be
4092 a Lam when floating the cast outwards. 
4093 
4094 I also discovered a missing side condition in the same equation, so fixing
4095 that is good too.  Now there is no loop when compiling ReadPrec.

4097 Should do a full nofib run though.

4109 a "needed given" (d7:Eq Int). That got everything confused.

4112        - first deals with methods/literals/dictionaries
4113        - then deals with implications

4252 
4253 Adopt Trac #1537.  The patch ended up a bit bigger than I expected,
4254 so I suggest we do not merge this into the 6.8 branch.  But there
4255 is no funadamental reason why not.
4256 
4257 With this patch, rebindable do-notation really does type as if you
4258 had written the original (>>) and (>>=) operations in desguared form.
4259 
4260 I ended up refactoring some of the (rather complicated) error-context
4261 stuff in TcUnify, by pushing an InstOrigin into tcSubExp and its
4262 various calls. That means we could get rid of tcFunResTy, and the
4263 SubCtxt type.  This should improve error messages slightly
4264 in complicated situations, because we have an Origin to hand
4265 to instCall (in the (isSigmaTy actual_ty) case of tc_sub1).
4266 
4267 Thanks to Pepe for the first draft of the patch.

4292[Move file locking into the RTS, fixing #629, #1109
4293Simon Marlow <simonmar@microsoft.com>**20071120140859
4294 File locking (of the Haskell 98 variety) was previously done using a
4295 static table with linear search, which had two problems: the array had
4296 a fixed size and was sometimes too small (#1109), and performance of
4297 lockFile/unlockFile was suboptimal due to the linear search.
4298 Also the algorithm failed to count readers as required by Haskell 98
4299 (#629).
4300 
4301 Now it's done using a hash table (provided by the RTS).  Furthermore I
4302 avoided the extra fstat() for every open file by passing the dev_t and
4303 ino_t into lockFile.  This and the improvements to the locking
4304 algorithm result in a healthy 20% or so performance increase for
4305 opening/closing files (see openFile008 test).

4418Simon Marlow <simonmar@microsoft.com>**20071116152148
4419 
4420 I think I figured out a reasonable way to manage the GHCi context,
4421 comments welcome.
4422 
4423 Rule 1: external package modules in the context are persistent.  That
4424 is, when you say 'import Data.Maybe' it survives over :load, :add,
4425 :reload and :cd.
4426 
4427 Rule 2: :load and :add remove all home-package modules from the
4428 context and add the rightmost target, as a *-module if possible.  This
4429 is as before, and makes sense for :load because we're starting a new
4430 program; the old home-package modules don't make sense any more.  For
4431 :add, it usually does what you want, because the new target will
4432 become the context.
4433 
4434 Rule 3: any modules from the context that fail to load during a
4435 :reload are remembered, and re-added to the context at the next
4436 successful :reload.
4437 
4438 Claus' suggestion about adding the "remembered" modules to the prompt
4439 prefixed with a ! is implemented but commented out.  I couldn't
4440 decide whether it was useful or confusing.
4441 
4442 One difference that people might notice is that after a :reload where
4443 there were errors, GHCi would previously dump you in the most recent
4444 module that it loaded.  Now it dumps you in whatever subset of the
4445 current context still makes sense, and in the common case that will
4446 probably be {Prelude}.

4572Simon Marlow <simonmar@microsoft.com>**20071114151411
4573 GHCi input is now treated universally as UTF-8, except for the Windows
4574 console where we do the correct conversion from the current code
4575 page (see System.Win32.stringToUnicode).
4576 
4577 That leaves non-UTF-8 locales on Unix as unsupported, but (a) we only
4578 accept source files in UTF-8 anyway, and (b) UTF-8 is quite ubiquitous
4579 as the default locale.

4599 There are actually three things here
4600 - INLINE pragmas weren't being pretty-printed properly
4601 - They were being classified into too-narrow boxes by eqHsSig
4602 - They were being printed in to much detail by hsSigDoc

4647     * Modify lexing of /../
4648     This makes /../ more like '..', so that a single / on a line doesn't
4649     trigger a parse error.  This should reduce the causes of accidental
4650     parse errors in Haddock comments; apparently stray / characters are
4651     a common source of failures.
