[FIX Trac #1935: generate superclass constraints for derived classes
simonpj@microsoft.com**20071128150541
 
 This bug only reports a problem with phantom types, but actually
 there was quite a long-standing and significant omission in the
 constraint generation for derived classes.  See
 Note [Superclasses of derived instance] in TcDeriv.
 
 The test deriving-1935 tests both cases.

  It used to be a synonym for ":r" in 6.6.1, but this wasn't documented or

simonpj@microsoft.com**20071121174914
 
 Adopt Trac #1537.  The patch ended up a bit bigger than I expected,
 so I suggest we do not merge this into the 6.8 branch.  But there
 is no funadamental reason why not.
 
 With this patch, rebindable do-notation really does type as if you
 had written the original (>>) and (>>=) operations in desguared form.
 
 I ended up refactoring some of the (rather complicated) error-context
 stuff in TcUnify, by pushing an InstOrigin into tcSubExp and its
 various calls. That means we could get rid of tcFunResTy, and the
 SubCtxt type.  This should improve error messages slightly
 in complicated situations, because we have an Origin to hand
 to instCall (in the (isSigmaTy actual_ty) case of tc_sub1).
 
 Thanks to Pepe for the first draft of the patch.

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

[FIX Trac #1825: standalone deriving Typeable
simonpj@microsoft.com**20071120125732
 
 Standalone deriving of typeable now requires you to say

 which is exactly the shape of instance decl that is generated
 by a 'deriving( Typeable )' clause on the data type decl.
 
 This is a bit horrid, but it's the only consistent way, at least
 for now.  If you say something else, the error messages are helpful.

[Always do 'setup makefile' before building each library
Simon Marlow <simonmar@microsoft.com>**20071120103329
 This forces preprocessing to happen, which is necessary if any of the
 .hsc files have been modified.  Without this change, a 'setup
 makefile' would be required by hand after a .hsc file changed.
 Fortunately 'setup makefile' isn't much extra work, and I've made it
 not overwrite GNUmakefile if it hasn't changed, which avoids
 recalculating the dependencies each time.

[Attempt at fixing #1873, #1360
Simon Marlow <simonmar@microsoft.com>**20071116152148
 
 I think I figured out a reasonable way to manage the GHCi context,
 comments welcome.
 
 Rule 1: external package modules in the context are persistent.  That
 is, when you say 'import Data.Maybe' it survives over :load, :add,
 :reload and :cd.
 
 Rule 2: :load and :add remove all home-package modules from the
 context and add the rightmost target, as a *-module if possible.  This
 is as before, and makes sense for :load because we're starting a new
 program; the old home-package modules don't make sense any more.  For
 :add, it usually does what you want, because the new target will
 become the context.
 
 Rule 3: any modules from the context that fail to load during a
 :reload are remembered, and re-added to the context at the next
 successful :reload.
 
 Claus' suggestion about adding the "remembered" modules to the prompt
 prefixed with a ! is implemented but commented out.  I couldn't
 decide whether it was useful or confusing.
 
 One difference that people might notice is that after a :reload where
 there were errors, GHCi would previously dump you in the most recent
 module that it loaded.  Now it dumps you in whatever subset of the
 current context still makes sense, and in the common case that will
 probably be {Prelude}.

 That leaves non-UTF-8 locales on Unix as unsupported, but (a) we only
 accept source files in UTF-8 anyway, and (b) UTF-8 is quite ubiquitous
 as the default locale.

[Fix build
David Waern <david.waern@gmail.com>**20071114125842
 I had forgot to update HaddockLex.hi-boot-6, so the build with 6.2.2 
 failed. This fixes that.

[FIX Trac 1662: actually check for existentials in proc patterns
simonpj@microsoft.com**20071114112930
 
 I'd fixed the bug for code that should be OK, but had forgotten to 
 make the test for code that should be rejected! 
 
 Test is arrowfail004

[FIX Trac 1888; duplicate INLINE pragmas
simonpj@microsoft.com**20071114104701
 
 There are actually three things here
 - INLINE pragmas weren't being pretty-printed properly
 - They were being classified into too-narrow boxes by eqHsSig
 - They were being printed in to much detail by hsSigDoc
 
 All easy.  Test is rnfail048.

[GHCi debugger: added a new flag, -fno-print-binding-contents
Pepe Iborra <mnislaih@gmail.com>**20071113174539
 
 The contents of bindings show at breakpoints and by :show bindings
 is rendered using the same printer that :print uses.
 But sometimes the output it gives spans over too many lines and the
 user may want to be able to disable it.

[Merge from Haddock: Modify lexing of /../
David Waern <david.waern@gmail.com>**20071112023856
 
   Tue Aug 28 11:19:54 CEST 2007  Simon Marlow <simonmar@microsoft.com>
     * Modify lexing of /../ 
     This makes /../ more like '..', so that a single / on a line doesn't
     trigger a parse error.  This should reduce the causes of accidental
     parse errors in Haddock comments; apparently stray / characters are
     a common source of failures.
 
 Please merge this to the 6.8.2 branch.
