      Fix trac # 5486 · fe60dd4a
      dterei authored
      LLVM has a problem when the user imports some FFI types
      like memcpy and memset in a manner that conflicts with
      the types that GHC uses internally.
      So now we pre-initialise the environment with the most
      general types for these functions.

      enable ARM specific target data layout and triple again · 748883b4
      kgardas authored
      This patch is allowed by the 'on ARMv7 with VFPv3[D16] support pass
       appropriate -mattr value to LLVM llc' patch. The trick is that LLVM
      by default (probably!) does not enable VFP, but GHC requires it
      so LLVM's llc asserts on unavailable floating point register. i.e. GHC/LLVM
      backend compiles into LLVM code which is using floats, but llc thinks
      no float regs for this are available. Passing appropriate llc option
      which is implemented in patch mentioned above fixes this issue.

      Refactoring: explicitly mark whether we have an info table in RawCmm · 41ca0b8d
      batterseapower authored
      I introduced this to support explicitly recording the info table label
      in RawCmm for another patch I am working on, but it turned out to lead
      to significant simplification in those parts of the compiler that
      consume RawCmm.
      Now, instead of lots of tests for null [CmmStatic] we have a simple
      test of a Maybe, and have reduced the number of guys that need to know
      how to convert entry->info labels by a TON. There are only 3 callers
      of that function now!

      Refactoring: use a structured CmmStatics type rather than [CmmStatic] · 54843b5b
      batterseapower authored
      I observed that the [CmmStatics] within CmmData uses the list in a very stylised way.
      The first item in the list is almost invariably a CmmDataLabel. Many parts of the
      compiler pattern match on this list and fail if this is not true.
      This patch makes the invariant explicit by introducing a structured type CmmStatics
      that holds the label and the list of remaining [CmmStatic].
      There is one wrinkle: the x86 backend sometimes wants to output an alignment directive just
      before the label. However, this can be easily fixed up by parameterising the native codegen
      over the type of CmmStatics (though the GenCmmTop parameterisation) and using a pair
      (Alignment, CmmStatics) there instead.
      As a result, I think we will be able to remove CmmAlign and CmmDataLabel from the CmmStatic
      data type, thus nuking a lot of code and failing pattern matches. This change will come as part
      of my next patch.

      LLVM: Support LLVM 2.9 (#5103) · 50e0db45
      dterei authored
      Instead of using the GNU As subsection feature on Linux/Windows
      for TNTC we now use the LLVM Mangler on all platforms.

      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.
