[Change the representation of the MVar blocked queue
Simon Marlow <marlowsd@gmail.com>**20100401091605
 Ignore-this: 20a35bfabacef2674df362905d7834fa
 
 The list of threads blocked on an MVar is now represented as a list of
 separately allocated objects rather than being linked through the TSOs
 themselves.  This lets us remove a TSO from the list in O(1) time
 rather than O(n) time, by marking the list object.  Removing this
 linear component fixes some pathalogical performance cases where many
 threads were blocked on an MVar and became unreachable simultaneously
 (nofib/smp/threads007), or when sending an asynchronous exception to a
 TSO in a long list of thread blocked on an MVar.
 
 MVar performance has actually improved by a few percent as a result of
 this change, slightly to my surprise.
 
 This is the final cleanup in the sequence, which let me remove the old
 way of waking up threads (unblockOne(), MSG_WAKEUP) in favour of the
 new way (tryWakeupThread and MSG_TRY_WAKEUP, which is idempotent).  It
 is now the case that only the Capability that owns a TSO may modify
 its state (well, almost), and this simplifies various things.  More of
 the RTS is based on message-passing between Capabilities now.

 This fixes #3838, and was made possible by the new BLACKHOLE

 doubly-linked, which entails some extra trickiness with regard to
 GC write barriers and suchlike.

 This replaces the global blackhole_queue with a clever scheme that
 enables us to queue up blocked threads on the closure that they are
 blocked on, while still avoiding atomic instructions in the common
 case.
 
 Advantages:
 
  - gets rid of a locked global data structure and some tricky GC code
    (replacing it with some per-thread data structures and different
    tricky GC code :)
 
  - wakeups are more prompt: parallel/concurrent performance should
    benefit.  I haven't seen anything dramatic in the parallel
    benchmarks so far, but a couple of threading benchmarks do improve
    a bit.
 
  - waking up a thread blocked on a blackhole is now O(1) (e.g. if
    it is the target of throwTo).
 
  - less sharing and better separation of Capabilities: communication
    is done with messages, the data structures are strictly owned by a
    Capability and cannot be modified except by sending messages.
 
  - this change will utlimately enable us to do more intelligent
    scheduling when threads block on each other.  This is what started
    off the whole thing, but it isn't done yet (#3838).
 
 I'll be documenting all this on the wiki in due course.

[do_checks: do not set HpAlloc if the stack check fails
Simon Marlow <marlowsd@gmail.com>**20100325110328
 Ignore-this: 899ac8c29ca975d03952dbf4608d758
 
 This fixes a very rare heap corruption bug, whereby
 
  - a context switch is requested, which sets HpLim to zero
    (contextSwitchCapability(), called by the timer signal or
    another Capability).
 
  - simultaneously a stack check fails, in a code fragment that has
    both a stack and a heap check.
 
 The RTS then assumes that a heap-check failure has occurred and
 subtracts HpAlloc from Hp, although in fact it was a stack-check
 failure and retreating Hp will overwrite valid heap objects.  The bug
 is that HpAlloc should only be set when Hp has been incremented by the
 heap check.  See comments in rts/HeapStackCheck.cmm for more details.
 
 This bug is probably incredibly rare in practice, but I happened to be
 working on a test that triggers it reliably:
 concurrent/should_run/throwto001, compiled with -O -threaded, args 30
 300 +RTS -N2, run repeatedly in a loop.

[Tweak the Makefile code for making .a libs; fixes trac #3642
Ian Lynagh <igloo@earth.li>**20100323221325
 The main change is that, rather than using "xargs ar" we now put
 all the filenames into a file, and do "ar @file". This means that
 ar adds all the files at once, which works around a problem where
 files with the same basename in a later invocation were overwriting
 the existing file in the .a archive.

 Fixes a rare crash in the parallel GC.
 
 If we copy a closure non-atomically during GC, as we do for all
 immutable values, then before writing the forwarding pointer we better
 make sure that the closure itself is visible to other threads that
 might follow the forwarding pointer.  I imagine this doesn't happen
 very often, but I just found one case of it: in scavenge_stack, the
 RET_FUN case, after evacuating ret_fun->fun we then follow it and look
 up the info pointer.
