  1. Fix a bug related to threads blocked on blackholes

    Simon Marlow authored
    We weren't making them live early enough, with the result that
    finalizable objects referred to only by a thread blocked on a black
    hole could be finalized too early (see conc057 test).
  2. Reorganisation of the source tree

    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.

    GHC.Base.breakpoint isn't vaporware anymore.

    Lemmih authored
    -fignore-breakpoints can be used to ignore breakpoints.
  4. Add SA_RESTART flag to the timer signal handler.

    Simon Marlow authored
    This seems to be necessary to prevent readline being confused by our
    SIGALRM handler.

  3. fix profiling on Win32

    Simon Marlow authored
    The recent patch to free memory in hs_exit() on Win32 unfortunately broke
    profiling, because it freed the memory slightly too early.

    This gives some control over affinity, while we figure out the best
    way to automatically schedule threads to make best use of the
    available parallelism.
    
    In addition to the primitive, there is also:
     
      GHC.Conc.forkOnIO :: Int -> IO () -> IO ThreadId
    
    where 'forkOnIO i m' creates a thread on Capability (i `rem` N), where
    N is the number of available Capabilities set by +RTS -N.
    
    Threads forked by forkOnIO do not automatically migrate when there are
    free Capabilities, like normal threads do.  Still, if you're using
    forkOnIO exclusively, it's a good idea to do +RTS -qm to disable work
    pushing anyway (work pushing takes too much time when the run queues
    are large, this is something we need to fix).

    This is pretty important when using the linker/bytecode-compiler from binaries
    other than GHCi.

    For now, I've added a TODO comment, but sooner or later this will have to
    be made gcc-version-independent.

  1. fix a warning

  2. Add some more flexibility to the multiproc scheduler

    Simon Marlow authored
    There are two new options in the -threaded RTS:
     
      -qm       Don't automatically migrate threads between CPUs
      -qw       Migrate a thread to the current CPU when it is woken up
    
    previously both of these were effectively off, i.e. threads were
    migrated between CPUs willy-milly, and threads were always migrated to
    the current CPU when woken up.  This is the first step in tweaking the
    scheduling for more effective work balancing, there will no doubt be
    more to come.

    mkDerivedConstants.c depends on ghcplatform.h

    dcoutts authored
    I think this missing dep is what broke my parallel build
    I used make -j2 with ghc-6.4.2.20060323 and got:
    
    ------------------------------------------------------------------------
    ==fptools== make boot -wr --jobserver-fds=3,11 -j;
    in /var/tmp/portage/ghc-6.4.2_pre20060323/work/ghc-6.4.2.20060323/ghc/includes
    ------------------------------------------------------------------------
    Creating ghcplatform.h...
    Done.
    gcc -O -O2 -march=k8 -pipe -Wa,--noexecstack    -c mkDerivedConstants.c -o mkDerivedConstants.o
    In file included from ghcconfig.h:5,
                     from Stg.h:42,
                     from Rts.h:19,
                     from mkDerivedConstants.c:20:
    ghcplatform.h:1:1: unterminated #ifndef
    Done.
    						    
    With this patch applied I can no longer repoduce this build bug.
    So I think this patch should be applied to the cvs ghc-6-4-branch too.

  3. gcc is getting smarter, so we need to hit it with a bigger stick

    Simon Marlow authored
    On x86_64 we are using C argument registers for global registers in
    the STG machine.  This is always going to be problematic when it comes
    to making C calls from STG and compiling via C.  Prior to GCC 4.1.0
    (approx) it was possible to just assign the argument expressions to
    temporaries to avoid a clash.  Now, we need to add an extra dummy
    function call as a barrier between the temporary assignments and the
    actual call.  The dummy call is removed by the mangler.
