When using -H<size> in SMP mode, divide the total nursery size amongst
the various nurseries.  -H<size> now does something reasonable with
SMP.

Hold the sm_mutex around access to the mutable list.

The SMP RTS now seems quite stable, I've run my simple test program
with 64 threads without crashes.

fprintf(stderr,..) --> debugBelch(...)

Some extra sanity checking

initCapability: initialise the rInHaskell field (found by Valgrind)

expandTaskTable: we need to update the hash table too
  (found by: Valgrind :-)

initTaskManager: take into account -N flag when sizing the initial
task table.

i386 wibble

Support for returning the renamed syntax from checkModule (untested).

x86_64: hang register parameters off the call instruction, like
powerpc does.  This gives the register allocator better information.

showReg(x86_64): fix
callerSaves: fix

Fix the volatile regs to the suspendThread call

Remove uses of stderr from .cmm code.

We can't reliably refer to stdin/stdout/stderr from .cmm, because the
C standard doesn't specify whether stderr is a variable or a macro.

Add comment

newTempName: instead of bumping the processId until we find a name
that isn't used, add an integer suffix to the processId.  This should
prevent temp-file conflicts that appear to have been affecting our
nightly builds and occasionally make -j.

The right way to allocate a temporary file is to create it straight
away, but I'm not sure of the implications of passing existing
temporary files to the various sub-processes that GHC executes, hence
this fix instead.

resetStaticObjectForRetainerProfiling: catch up changes in ClosureMacros.h

When chasing explicit imports, we now look for the module in both the
home package and external packages, and complain if it is found in
both:

Chasing modules from: Overlap
Cannot import `List':
  it was found in both overlap/List.hs and package haskell98-1.0.
  Possible fix: -ignore-package haskell98-1.0
  (imported from overlap/Overlap.hs)

Previously the home module would have been ignored in favour of the
package module.  It means we're doing a bit more searching, but the
behaviour is less obscure.

Back out previous revision.

It appears that passing -g to the assembly phase of C compilation
results in an object file with broken debug info, that gdb can't
read.  This is probably a bug in gcc and/or binutils, but this change
means that I can't avoid it (unless we were to hack the pipeline to
do .c->.s->.o in one stage instead of two).

Add entry about non-blocking stdin and System.Cmd.{system,rawSystem}.

runSomething: 'rawSystem' might raise an exception to indicate that
'pgm' couldn't be executed, so catch this here & report.

Merge to STABLE.

scavenge_one: fix reversed PAP/AP cases

Partial support for deadlock detection in the threaded/SMP RTS.

The idea is to wait until a complete time slice has gone by without
running any Haskell code, and then try doing a GC to detect deadlocked
threads.

This kind of works: but we can only wake up a worker thread from the
signal handler if there's another worker running - we can't wake up the
current thread, it seems.

interruptStgRts: call threadRunnable().  This might not work properly
from a signal handler, but it's all we can do (and seems to do
something reasonable on Linux).

atomicModifyMutVarzh_fast: move the sm_mutex acquisition *after* the
heap check

Yet another StgClosure that should be StgThunk

stg_raise: we should by using StgThunk_payload(), not StgClosure_payload()

Requested by Duncan Coutts: -optc flags get passed to the assembler
phase too.  It's not obvious, when using GHC to compile a .c file,
that options need to be passed both with -optc and -opta - gcc doesn't
need this, for example.

This is an experimental change - if it breaks anything we can back it
out.  If anyone needs to pass flags to the .c->.s phase *only*, then
we will need to add another flag for that purpose.  It seems unlikely,
though (there aren't many flags that affect the assembler only, and
those that do don't conflict with flags for the C phase).

Fix comment

ATTENTION: Make it compile again, but only via a wild and probably
wrong guess which might break GHCi. SimonM, please have a look at
this. (Who broke it should fix it! :-)
