      Explicitly share some return continuations · 6ede0067
      Simon Marlow authored
      Instead of relying on common-block-elimination to share return
      continuations in the common case (case-alternative heap checks) we do
      it explicitly.  This isn't hard to do, is more robust, and saves some
      compilation time.  Full commentary in Note [sharing continuations].

      Lower safe foreign calls in the new CmmLayoutStack · 93e42a68
      Simon Marlow authored
      We also generate much better code for safe foreign calls (and maybe
      also unsafe foreign calls) than previously.  See the two new Notes:
      
      Note [lower safe foreign calls]
      Note [safe foreign call convention]

      New stack layout algorithm · 76999b60
      Simon Marlow authored
      Also:
       - improvements to code generation: push slow-call continuations
         on the stack instead of generating explicit continuations
      
       - remove unused CmmInfo wrapper type (replace with CmmInfoTable)
      
       - squash Area and AreaId together, remove now-unused RegSlot
      
       - comment out old unused stack-allocation code that no longer
         compiles after removal of RegSlot

      Merge in new code generator branch. · 889c084e
      Simon Marlow authored
      This changes the new code generator to make use of the Hoopl package
      for dataflow analysis.  Hoopl is a new boot package, and is maintained
      in a separate upstream git repository (as usual, GHC has its own
      lagging darcs mirror in http://darcs.haskell.org/packages/hoopl).
      
      During this merge I squashed recent history into one patch.  I tried
      to rebase, but the history had some internal conflicts of its own
      which made rebase extremely confusing, so I gave up. The history I
      squashed was:
      
        - Update new codegen to work with latest Hoopl
        - Add some notes on new code gen to cmm-notes
        - Enable Hoopl lag package.
        - Add SPJ note to cmm-notes
        - Improve GC calls on new code generator.
      
      Work in this branch was done by:
         - Milan Straka <fox@ucw.cz>
         - John Dias <dias@cs.tufts.edu>
         - David Terei <davidterei@gmail.com>
      
      Edward Z. Yang <ezyang@mit.edu> merged in further changes from GHC HEAD
      and fixed a few bugs.
