Remove an unnecessary finger check when re-marking roots.

The finger check, a less than check, is meaningful only during the
initial root marking.  After root marking, the finger is set to the
end of the virtual address space and the check always succeeds.  As
such, this check is superfluous during all other phases of garbage
collection as it always suceeds.

  % adb shell setprop dalvik.vm.extra-opts -Xprofile:wallclock
  % adb shell start

This also changes the somewhat nebulous "clock=global" trace header line

about breaking compatibility.

While I was in here, I fixed a couple of problems caused by failure to

Change the way thread suspension works.

There are at least three ways to handle detection of thread suspension
correctly: (1) hold a mutex, (2) pile all state into a single 32-bit
location and use atomic ops, and (3) order the operations carefully.
Of these, #3 has the least overhead on uniprocessors, so we're going
with that.

It does introduce one quirk, because we're now changing to "running"
mode before checking to see if we're allowed to run.  This creates
a tiny window of opportunity for assertions and thread dumps to see
what appears to be a thread that's running when it shouldn't be.
This is correctable with additional work (e.g. transitioning through
a pre-running state) but probably not worth worrying about.

This eliminates the separate self->isSuspended flag in favor of the
new THREAD_SUSPENDED thread state.

Andy McFadden [Mon, 23 Aug 2010 23:45:24 +0000 (16:45 -0700)]
Change the way thread suspension works.

There are at least three ways to handle detection of thread suspension
correctly: (1) hold a mutex, (2) pile all state into a single 32-bit
location and use atomic ops, and (3) order the operations carefully.
Of these, #3 has the least overhead on uniprocessors, so we're going
with that.

It does introduce one quirk, because we're now changing to "running"
mode before checking to see if we're allowed to run.  This creates
a tiny window of opportunity for assertions and thread dumps to see
what appears to be a thread that's running when it shouldn't be.
This is correctable with additional work (e.g. transitioning through
a pre-running state) but probably not worth worrying about.

This eliminates the separate self->isSuspended flag in favor of the
new THREAD_SUSPENDED thread state.

Always support debugging and profiling.

This eliminates the use of the WITH_DEBUGGER and WITH_PROFILER
conditional compilation flags.  We've never shipped a device without
these features, and it's unlikely we ever will.  They're not worth
the code clutter they cause.

As usual, since I can't test the x86-atom code I left that alone and
added an item to the TODO list.

Fix a critical space leak introduced by concurrent sweeping.

When computing the bitmaps for each heap, the live bitmap was assumed
to have greater extent than the mark bitmap.  With the concurrent
sweep the mark and live bitmaps are swapped before the sweep bitmaps
are computed.  As such, the live bitmap extent is always less than or
equal to the mark bitmap.  A benchmark which loops creating objects
just to drop them on the floor will exclude most objects in the heap
as candidates for sweeping and will exhaust the heap.

The change fixes the extent computation and reintroduces an assert to
check that the bitmap we assume to be the largest is the largest.
