      RTS tidyup sweep, first phase · a2a67cd5
      Simon Marlow authored
      The first phase of this tidyup is focussed on the header files, and in
      particular making sure we are exposinng publicly exactly what we need
      to, and no more.
      
       - Rts.h now includes everything that the RTS exposes publicly,
         rather than a random subset of it.
      
       - Most of the public header files have moved into subdirectories, and
         many of them have been renamed.  But clients should not need to
         include any of the other headers directly, just #include the main
         public headers: Rts.h, HsFFI.h, RtsAPI.h.
      
       - All the headers needed for via-C compilation have moved into the
         stg subdirectory, which is self-contained.  Most of the headers for
         the rest of the RTS APIs have moved into the rts subdirectory.
      
       - I left MachDeps.h where it is, because it is so widely used in
         Haskell code.
       
       - I left a deprecated stub for RtsFlags.h in place.  The flag
         structures are now exposed by Rts.h.
      
       - Various internal APIs are no longer exposed by public header files.
      
       - Various bits of dead code and declarations have been removed
      
       - More gcc warnings are turned on, and the RTS code is more
         warning-clean.
      
       - More source files #include "PosixSource.h", and hence only use
         standard POSIX (1003.1c-1995) interfaces.
      
      There is a lot more tidying up still to do, this is just the first
      pass.  I also intend to standardise the names for external RTS APIs
      (e.g use the rts_ prefix consistently), and declare the internal APIs
      as hidden for shared libraries.

      Use MD5 checksums for recompilation checking (fixes #1372, #1959) · 526c3af1
      Simon Marlow authored
      This is a much more robust way to do recompilation checking.  The idea
      is to create a fingerprint of the ABI of an interface, and track
      dependencies by recording the fingerprints of ABIs that a module
      depends on.  If any of those ABIs have changed, then we need to
      recompile.
      
      In bug #1372 we weren't recording dependencies on package modules,
      this patch fixes that by recording fingerprints of package modules
      that we depend on.  Within a package there is still fine-grained
      recompilation avoidance as before.
      
      We currently use MD5 for fingerprints, being a good compromise between
      efficiency and security.  We're not worried about attackers, but we
      are worried about accidental collisions.
      
      All the MD5 sums do make interface files a bit bigger, but compile
      times on the whole are about the same as before.  Recompilation
      avoidance should be a bit more accurate than in 6.8.2 due to fixing
      #1959, especially when using -O.

      Reorganisation of the source tree · 0065d5ab
      Simon Marlow authored
      Most of the other users of the fptools build system have migrated to
      Cabal, and with the move to darcs we can now flatten the source tree
      without losing history, so here goes.
      
      The main change is that the ghc/ subdir is gone, and most of what it
      contained is now at the top level.  The build system now makes no
      pretense at being multi-project, it is just the GHC build system.
      
      No doubt this will break many things, and there will be a period of
      instability while we fix the dependencies.  A straightforward build
      should work, but I haven't yet fixed binary/source distributions.
      Changes to the Building Guide will follow, too.
