      Generalize exposed-modules field in installed package database · e14a9732
      Edward Z. Yang authored
      
      
      Summary:
      Instead of recording exposed-modules and reexported-modules as seperate
      fields in the installed package database, this commit merges them into
      a single field (exposed-modules).  The motivation for this change is
      in preparation for the inclusion of *signatures* into the installed
      package database, which may also be reexported.  Merging the representation
      means that we can treat reexports uniformly, no matter if they're a normal
      module or a signature.
      
      This commit adds a stub for signatures, but that code isn't wired up to
      anything yet.
      
      Contains Cabal submodule update to accommodate these changes.

      Fix #9404 by removing tcInfExpr. · 1e2002d8
      eir@cis.upenn.edu authored
      See the ticket for more info about the new algorithm. This is a small
      simplification, unifying the treatment of type checking in a few
      similar situations.

      Fix #9788 by giving `coerce` the right type. · 294ac47e
      eir@cis.upenn.edu authored
      No test case added, as the original mistake is just one level
      up from a typo.

      Fix #9066. · d782694f
      eir@cis.upenn.edu authored
      When splicing in a fixity declaration, look for both term-level things
      and type-level things. This requires some changes elsewhere in the
      code to allow for more flexibility when looking up Exact names, which
      can be assigned the wrong namespace during fixity declaration
      conversion.
      
      See the ticket for more info.

      Per-thread allocation counters and limits · d70b19bf
      Simon Marlow authored
      This reverts commit f0fcc41d.
      
      New changes: now works on 32-bit platforms too.  I added some basic
      support for 64-bit subtraction and comparison operations to the x86
      NCG.

      Implement new integer-gmp2 from scratch (re #9281) · c774b28f
      Herbert Valerio Riedel authored
      This is done as a separate `integer-gmp2` backend library because it
      turned out to become a complete rewrite from scratch.
      
      Due to the different (over)allocation scheme and potentially different
      accounting (via the new `{shrink,resize}MutableByteArray#` primitives),
      some of the nofib benchmarks actually results in increased allocation
      numbers (but not necessarily an increase in runtime!).  I believe the
      allocation numbers could improve if `{resize,shrink}MutableByteArray#`
      could be optimised to reallocate in-place more efficiently.
      
      Here are the more apparent changes in the latest nofib comparision
      between `integer-gmp` and `integer-gmp2`:

      (see P35 / https://phabricator.haskell.org/P35 for full report)
      
      By default, `INTEGER_LIBRARY=integer-gmp2` is active now, which results
      in the package `integer-gmp-1.0.0.0` being registered in the package db.
      The previous `integer-gmp-0.5.1.0` can be restored by setting
      `INTEGER_LIBRARY=integer-gmp` (but will probably be removed altogether
      for GHC 7.12). In-tree GMP support has been stolen from the old
      `integer-gmp` (while unpatching the custom memory-allocators, as well as
      forcing `-fPIC`)
      
      A minor hack to `ghc-cabal` was necessary in order to support two different
      `integer-gmp` packages (in different folders) with the same package key.
      
      There will be a couple of follow-up commits re-implementing some features
      that were dropped to keep D82 minimal, as well as further
      clean-ups/improvements.
