      Major Call Arity rework · cb8a63cb
      Joachim Breitner authored
      This patch improves the call arity analysis in various ways.
      
      Most importantly, it enriches the analysis result information so that
      when looking at a call, we do not have to make a random choice about
      what side we want to take the information from. Instead we can combine
      the results in a way that does not lose valuable information.
      
      To do so, besides the incoming arities, we store remember "what can be
      called with what", i.e. an undirected graph between the (interesting)
      free variables of an expression. Of course it makes combining the
      results a bit more tricky (especially mutual recursion), but still
      doable.
      
      The actually implemation of the graph structure is abstractly put away
      in a module of its own (UnVarGraph.hs)
      
      The implementation is geared towards efficiently representing the graphs
      that we need (which can contain large complete and large complete
      bipartite graphs, which would be huge in other representations). If
      someone feels like designing data structures: There is surely some
      speed-up to be obtained by improving that data structure.
      
      Additionally, the analysis now takes into account that if a RHS stays a
      thunk, then its calls happen only once, even if the variables the RHS is
      bound to is evaluated multiple times, or is part of a recursive group.

      Make distribution tarball compression format configurable · 32f41c79
      Herbert Valerio Riedel authored
      
      
      By default, bzip2 compression is selected (which is what has been used
      till now). Additionally, by setting the TAR_COMP make variable to one of
      the values "bzip2", "gzip", or "xz", an explicit compression format can
      be requested for the distribution tarballs. For instance, invoking
      
        make TAR_COMP=xz sdist-ghc
      
      will result in a tarball `./sdistprep/ghc-7.9.20140226-src.tar.xz`

      Fix #8807. · 98b6756b
      eir@cis.upenn.edu authored
      It turns out that the enhanced repPred function in DsMeta assumed
      that the head of any constraint would be a tycon. This assumption
      is false. Happily, the solution involved *deleting* code. I
      just removed repPred in favor of repTy, and added the HsEqTy case
      to repTy, where it should be anyway.
