Add opcodes for volatile field accesses
This adds instructions for {i,s}{get,put}{,-object}-volatile, for a
total of eight new instructions.
On SMP systems, these instructions will be substituted in for existing
field access instructions, either by dexopt or during just-in-time
verification. Unlike the wide-volatile instructions, these will not be
used at all when the VM is not built for SMP.
(Ideally we'd omit the volatile instruction implementations entirely on
non-SMP builds, but that requires a little work in gen-mterp.py.)
The change defines and implements the opcodes and support methods, but
does not cause them to be used.
Also, changed dvmQuasiAtomicRead64's argument to be const.

Dalvik SMP update
Fix some SMP correctness issues in the VM:
- Correct AtomicCache implementation, inserting barriers where needed
and correcting existing usage.
- Emphasize that String startup isn't expected to be reentrant, and
use atomic ops to ensure that we explode if anybody tries it.
- Use 64-bit quasiatomic ops to manage the "last activity" timer in
JDWP. (Also, provide some documented but unimplemented behavior.)
- Updated the volatile operations in sun.misc.Unsafe to include
appropriate barriers.
(This does not purport to correct all SMP issues, just some of the
more obvious ones.)

Elliott Hughes [Thu, 17 Jun 2010 20:19:01 +0000 (13:19 -0700)]
Move the implementation of JNIHelp.h's FileDescriptor helpers into JNIHelp.c.
These functions used to be declared in dalvik/ but defined in libcore/, which
was a layering violation but not important. It now stands in the way of
switching FileDescriptor's JNI over to C++, so out it goes.
There's a functional change here: the libcore code was going out of its way
to ensure that FileDescriptor's <clinit> was being invoked, but it's not
obvious that there was any reason for this: the static initializers just set
the err/in/out fields' descriptor fields to the appropriate integers.
A separate change rewrites FileDescriptor's JNI in terms of JNIHelp.h's API,
so it no longer needs to know anything about FileDescriptor itself. (Amusingly,
the original motivation for switching to C++ was to rewrite code that I've now
simply deleted.)

Tags are unconditionally added before references are added to the
reference queue. This tag is checked when a reference is removed from
the queue and subsequently cleared. There are no other observers of
this tag and so it is equivalent to not tag the reference in the first
place. The original intent may have been to tag the references in
different ways. Removing this code simplifies reference tracing.

JIT: Trace selection tuning to reduce number of spurious "hot" traces.
This change trades a smallish adverse performance impact on programs
with flat execution profiles (for example, dacapo's xalan) for significant
reductions in useless translations. For dacapo, performance dropped
by about 2% in return for a 40% reduction in memory usage (300 Kbytes).
No significant performance drop in loopy profiles, but ocassionally good
memory savings. BenchmarkPi performance unchanged, but memory usage
after 4 runs went from 120 Kbytes to 55 Kbytes.
This is still not ideal (and probably will never be). For programs with
flat execution profiles we do best with loose hotness detection - try to
get as much of the working set compiled as quickly as possible. However,
too loose and we end up translating a lot of little-used UI code.
My current inclination is to err towards tight standards for the trace
JIT and push better performance for flat profiles in a future world in
which we analyze profile data across runs - perhaps in conjunction with
a method JIT.

Send unlinkedClass back to hell, as requested.
The GC and Verify routines now can look inside classes better as well.
Basic ideas:
1) Pre-allocate the java.lang.Class class, and explicitly
set its clazz field to itself.
2) Put ClassObjects in status CLASS_IDX when their super and interface
array contain Dex indexes rather than object pointers. The GC
understands this, and uses that status to decide on marking those
fields or not.

Make attached threads visible to the GC sooner
Threads that are created outside the VM and then attached were
allocating objects (Thread, VMThread, a String for the name) before
they were on the internal thread list. This made for some awkward
moments and required the use of an ALLOC_NO_GC flag.
With this change we now add the thread to the list first, and perform
the object creation afterward. This is saner from the perspective
of the GC, and may allow us to eliminate ALLOC_NO_GC.
As it happens, the places that would care about a null threadObj
(thread dump, get thread name, debugger request for thread list)
already check for it, making this pretty straightforward.
While I was in here I also took some steps to ensure that threadObj
doesn't get rewritten by the copying collector while something is in
the process of examining it. This involved a bit of paranoia in the
thread dump.

Add a callback driven visitor routine and make verify use it.
This is the first step along the way to ending the proliferation of
one-off object walking routines. This code should supersede similar
code in the mark sweep collector, the copying collector, the hprof
tool, etc.. Once all of its uses have been debugged the routines in
the .c file should be hoisted into the .h file and marked as inline.
Soon, the signature of the visitor will probably have to be converted
to a functor with members specialized to reference type and, in
addition, given an extra parameter for a context structure.
