      rts: unrust 'libbfd' debug symbols parser · cb0a503a
      Sergei Trofimovich authored
      
      
      Summary:
      Patch does the following:
      - fixes detection of working libbfd on modern linux
        platforms (where bfd_uncompress_section_contents is a macro)
      - disables 'bfd' by default and adds '--enable-bfd-debug'
        configure option. As bfd's ABI is unstable
        the feature is primarily useful by ghc hackers.
      
      Not done (subject for another patch):
      - one-time bfd object memory leak in DEBUG_LoadSymbols
      - in '-dynamic' mode debugging symbols are loaded only for
        current executable, not all libraries it is linked against.

      Implement `MIN_VERSION_GLASGOW_HASKELL()` macro · 3549c952
      Herbert Valerio Riedel authored
      This exposes the `cProjectPatchLevel{1,2}` value at the CPP level to
      allow it to be used in CPP conditionals. Concretely, GHC 7.10.2.20150623
      would result in
      
        #define __GLASGOW_HASKELL__             710
        #define __GLASGOW_HASKELL_PATCHLEVEL1__ 2
        #define __GLASGOW_HASKELL_PATCHLEVEL2__ 20150623
      
      while GHC 7.10.3 results in
      
        #define __GLASGOW_HASKELL__             710
        #define __GLASGOW_HASKELL_PATCHLEVEL1__ 3
      
      and finally GHC 7.9.20141009 results in
      
        #define __GLASGOW_HASKELL__             709
        #define __GLASGOW_HASKELL_PATCHLEVEL1__ 20141009
      
      As it's error-prone to properly express CPP conditionals for testing GHC
      multi-component versions, a new macro `MIN_VERSION_GLASGOW_HASKELL()` is
      provided (also via the new CPP include file `ghcversion.h`)
      
      Finally, in order to make it easier to define the new CPP macro
      `MIN_VERSION_GLASGOW_HASKELL()`, a new default-included
      `include/ghcversion.h` is used for the new CPP definitions.

      ghc.mk: fix list for dll-split on GHCi-less builds · 2a8ea474
      Sergei Trofimovich authored
      
      
      To reproduce build failure it's enough to try
      to build GHC on amd64 with the following setup:
      
          $ cat mk/build.mk
          # for #9552
          GhcWithInterpreter = NO
      
      It gives:
      
          Reachable modules from DynFlags out of date
          Please fix compiler/ghc.mk, or building DLLs on Windows may break (#7780)
          Redundant modules: Bitmap BlockId ... <list of 42 modules>
          <make error>
      
      dll-split among other things makes sure
      all mentioned modules are used by DynFlags.
      '#ifdef GHCI' keeps is from happening.
      
      Patch moves those 42 modules under
      'GhcWithInterpreter' guard.

      Rename _closure to _static_closure, apply naming consistently. · 35672072
      Edward Z. Yang authored
      
      
      Summary:
      In preparation for indirecting all references to closures,
      we rename _closure to _static_closure to ensure any old code
      will get an undefined symbol error.  In order to reference
      a closure foobar_closure (which is now undefined), you should instead
      use STATIC_CLOSURE(foobar).  For convenience, a number of these
      old identifiers are macro'd.
      
      Across C-- and C (Windows and otherwise), there were differing
      conventions on whether or not foobar_closure or &foobar_closure
      was the address of the closure.  Now, all foobar_closure references
      are addresses, and no & is necessary.
      
      CHARLIKE/INTLIKE were not changed, simply alpha-renamed.

      BC-breaking changes to C-- CLOSURE syntax. · 3b5a840b
      Edward Z. Yang authored
      
      
      Summary:
      Previously, there were two variants of CLOSURE in C--:
      
          - Top-level CLOSURE(foo_closure, foo, lits...), which defines a new
            static closure and gives it a name, and
      
          - Array CLOSURE(foo, lits...), which was used for the static char
            and integer arrays.
      
      They used the same name, were confusing, and didn't even generate
      the correct internal label representation!  So now, we have two
      new forms:
      
          - Top-level CLOSURE(foo, lits...) which automatically generates
            foo_closure (along with foo_info, which we were doing already)
      
          - Array ANONYMOUS_CLOSURE(foo, lits...) which doesn't generate
            a foo_closure identifier.

      Place static closures in their own section. · b23ba2a7
      Edward Z. Yang authored
      
      
      Summary:
      The primary reason for doing this is assisting debuggability:
      if static closures are all in the same section, they are
      guaranteed to be adjacent to one another.  This will help
      later when we add some code that takes section start/end and
      uses this to sanity-check the sections.

      Basic Python 3 support for testsuite driver (Trac #9184) · 084d241b
      Krzysztof Gogolewski authored
      Summary:
      Most of the changes is adaptation of old Python 2 only code.
      My priority was not breaking Python 2, and so I avoided bigger
      changes to the driver. In particular, under Python 3 the output
      is a str and buffering cannot be disabled.
      
      To test, define PYTHON=python3 in testsuite/mk/boilerplate.mk.
