      Fix Trac #3437: strictness of specialised functions · ef5376d5
      simonpj@microsoft.com authored
      'lilac' helpful pin-pointed a space leak that was due to a specialised
      function being insufficiently strict.  Here's the new comment in SpecConstr:
      Note [Transfer strictness]
      We must transfer strictness information from the original function to
      the specialised one.  Suppose, for example
        f has strictness     SS
              and a RULE     f (a:as) b = f_spec a as b
      Now we want f_spec to have strictess  LLS, otherwise we'll use call-by-need
      when calling f_spec instead of call-by-value.  And that can result in 
      unbounded worsening in space (cf the classic foldl vs foldl')
      See Trac #3437 for a good example.
      The function calcSpecStrictness performs the calculation.

      Rollback: use cas() to claim the closure in copyPart(), to match copy_tag() · 0a19869b
      Simon Marlow authored
      rolling back:
        * use cas() to claim the closure in copyPart(), to match copy_tag()
        * rename whitehole_spin to evac_collision, and update it properly
      This introduced a new failure in parallel GC.  I'll rollback for now
      until I've fixed it.

      Relax the assumption that all objects fit in a single block (#3424) · b99af863
      Simon Marlow authored
      It is possible for the program to allocate single object larger than a
      block, without going through the normal large-object mechanisms that
      we have for arrays and threads and so on.  
      The GC was assuming that no object was larger than a block, but #3424
      contains a program that breaks the assumption.  This patch removes the
      assumption.  The objects in question will still be copied, that is
      they don't get the normal large-object treatment, but this case is
      unlikely to occur often in practice.
      In the future we may improve things by generating code to allocate
      them as large objects in the first place.

      Restore the GHC version check · efc0f420

      I'm not sure what happened here, but the ordering of tests was messed
      up, with the result that the GHC version check was being omitted.

      Improvements to record puns, wildcards · d64022dc
      simonpj@microsoft.com authored
      * Make C { A.a } work with punning, expanding to C { A.a = a }
      * Make it so that, with -fwarn-unused-matches, 
              f (C {..}) = x
        does not complain about the bindings introduced by the "..".
      * Make -XRecordWildCards implies -XDisambiguateRecordFields.
      * Overall refactoring of RnPat, which had become very crufty. 
        In particular, there is now a monad, CpsRn, private to RnPat,
        which deals with the cps-style plumbing.  This is why so many
        lines of RnPat have changed.
      * Refactor the treatment of renaming of record fields into two passes
      	- rnHsRecFields1, used both for patterns and expressions,
      	     which expands puns, wild-cards
        	- a local renamer in RnPat for fields in patterns
      	- a local renamer in RnExpr for fields in construction and update
        This make it all MUCH easier to understand
      * Improve documentation of record puns, wildcards, and disambiguation
