 would probably mean moving to a more structured file format).

Simon Marlow <marlowsd@gmail.com>**20080827102414

 forces A to be loaded as byte-code.  See the manual for details.  The
 previous behaviour for specifying filenames vs. module names on the
 command line and in :load has been restored.
 
 The Target datatype has a new Bool field, which is True if the target
 is allowed to be loaded from compiled code, or False otherwise, so
 this functionality is available via the GHC API.  guessTarget
 understands the *-prefix form for specifying targets.

simonpj@microsoft.com**20080826122121
 
 This patch executes the plan described in the discussion in Trac #2497.
 Specficially:
 
     * Inside a RULE, switch on the forall-as-keyword in the lexer,
       unconditionally. (Actually this is done by an earlier patch.)
 
     * Merge the -XScopedTypeVariables and -XPatternSignatures flags,
       and deprecate the latter. Distinguishing them isn't senseless,
       but it's jolly confusing.
 
     * Inside a RULE, switch on -XScopedTypeVariables unconditionally. 
 
     * Change -frewrite-rules to -fenable-rewrite-rules; deprecate the former. 
       Internally the DynFlag is now Opt_EnableRewriteRules.
 
 There's a test in typecheck/should_compile/T2497.hs

[Fix a nasty float-in bug
simonpj@microsoft.com**20080822133427
 
 This is a long-standing bug in FloatIn, which I somehow managed to
 tickle (it's actually surprisingly hard to provoke which is why 
 it has not shown up before).
 
 The problem was that we had a specialisation like this:
 
   let
        f_spec = ...
   in let
        {-# RULE f Int = f_spec #-}
        f = ...
   in
        <body>
 
 The 'f_spec' binding was being floated inside the binding for 'f', 
 which makes the RULE invalid becuase 'f_spec' isn't in scope.
 
 We just need to add the free variables of the RULE in the right 
 places...
        
] 
[Make rule printing wobble less
simonpj@microsoft.com**20080821123100
 
 a) When generating specialisations, include the types in the name
    of the rule, to avoid having rules with duplicate names.
    (The rule name is used to put rules in canonical order for
    fingerprinting.)
 
 b) In Specialise and SpecConstr use a new function Rules.pprRulesForUser
    to print rules in canonical order.  This reduces unnecessary wobbling
    in test output, notably in T2486

[Don't use the cc-options from packages when compiling .hc files
Simon Marlow <marlowsd@gmail.com>**20080821155549
 Now that we don't include any header files in .hc apart from our own,
 the cc-options from packages are at best superfluous, so don't pass
 them.
 
 We still pass them to .c compilations, although I've just made changes
 to Cabal so that cc-options from a .cabal file are not copied into the
 InstalledPackageInfo.  Most uses of cc-options in Cabal are clearly
 intended to be local to the package, but they were being propagated
 everywhere, almost certainly unintentionally.
 
 The way is left open for Cabal to allow packages to specify cc-options
 that get propagated in the future, if we find a use case for this.

 The generation of record selectors for GADTs and the like was
 pretty screwed up.  This patch fixes it.
 
 Note that Unify.refineType is now used only in the generation of
 record seletctors -- but it really does seem to be needed there.

[Fix Trac #2412: type synonyms and hs-boot recursion
simonpj@microsoft.com**20080811122523
 
 Max Bolingbroke found this awkward bug, which relates to the way in
 which hs-boot files are handled.
 
    --> HEADS UP: interface file format change: recompile everything!
 
 When we import a type synonym, we want to *refrain* from looking at its
 RHS until we've "tied the knot" in the module being compiled.  (Reason:
 the type synonym might ultimately loop back to the module being compiled.)
 To achieve this goal we need to know the *kind* of the synonym without 
 looking at its RHS.  And to do that we need its kind recorded in the interface
 file.
 
 I slightly refactored the way that the IfaceSyn data constructor
 fields work, eliminating the previous tricky re-use of the same field
 as either a type or a kind.

simonpj@microsoft.com**20080811104438
 
 tcSimplifyRuleLhs is a cut-down constraint simplifier, intended for
 use in RULE left-hand-sides.  But it was written before implication
 constraints, and the exmaple of this bug report shows that when higher
 rank types are involved we need to be a bit cleverer.
 
 The whole business of simplifying constraints on rule LHSs is a bit
 of a hack; but for a good reason.  See the comments with tcSimplifyRuleLhs.
 This patch at least cures the crash.

[Make comparison on equalities work right (ie look at the types)

 This patch makes

 The comparison and equality instances for Insts are really only
 used in making the AvailEnv in TcSimplify, which equalities are
 never put into, which is why we've gotten away with this for so long.
 
 But I'm now using 'nub' in the error messages for equalities,
 and in any case it makes sense to have the right equality!

[FIX #2327: a fault in the thunk-selector machinery (again)
Simon Marlow <marlowsd@gmail.com>**20080729150518
 This program contains an expression of the form
 
    let x = snd (_, snd (_, snd (_, x)))
 
 (probably not explicitly, but that's what appears in the heap at
 runtime).  Obviously the program should deadlock if it ever enters
 this thing, but apparently the test program in #2327 never does.
 
 The GC tries to evaluate the snd closures, and gets confused due to
 the loop.  In particular the earlier fix for #1038 was to blame.

[Change the calling conventions for unboxed tuples slightly
Simon Marlow <marlowsd@gmail.com>**20080728155621
 When returning an unboxed tuple with a single non-void component, we
 now use the same calling convention as for returning a value of the
 same type as that component.  This means that the return convention
 for IO now doesn't vary depending on the platform, which make some
 parts of the RTS simpler, and fixes a problem I was having with making
 the FFI work in unregisterised GHCi (the byte-code compiler makes
 some assumptions about calling conventions to keep things simple).
