ART: Streaming trace mode
Add a streaming mode for tracing. Streaming uses a buffer of 16KB
and writes to the output when that buffer gets full. Streaming mode
can be enabled with -Xmethod-trace-stream and is currently not
exposed otherwise.
Add a python script that can parse the streaming format, which
simply contains strings for newly encountered threads and methods
inline, and create output that can be used with traceview.
Add Trace::Pause and Trace::Abort, which can pause and abort tracing.
Abort is different from Stop in that it does not write the data.
Add code to the zygote hooks JNI implementation that pauses tracing
before the fork, making sure that a child cannot clobber the parent's
data.
Add code to the zygote hooks JNI implementation that aborts old
tracing and starts new tracing in the child after the fork. Currently
base the output on the pid. This will not work on an unmodified
device, as the profiles directory is not generally writable, but
we do not have enough information at that point. Consider a scheme
that restarts tracing later.

Add JIT
Currently disabled by default unless -Xjit is passed in.
The proposed JIT is a method JIT which works by utilizing interpreter
instrumentation to request compilation of hot methods async during
runtime.
JIT options:
-Xjit / -Xnojit
-Xjitcodecachesize:N
-Xjitthreshold:integervalue
The JIT has a shared copy of a compiler driver which is accessed
by worker threads to compile individual methods.
Added JIT code cache and data cache, currently sized at 2 MB
capacity by default. Most apps will only fill a small fraction of
this cache however.
Added support to the compiler for compiling interpreter quickened
byte codes.
Added test target ART_TEST_JIT=TRUE and --jit for run-test.
TODO:
Clean up code cache.
Delete compiled methods after they are added to code cache.
Add more optimizations related to runtime checks e.g. direct pointers
for invokes.
Add method recompilation.
Move instrumentation to DexFile to improve performance and reduce
memory usage.

ART: Allow the execution to stop if the compilation fails via an option
The current implementation continues the execution of the application if
dex2oat fails by relying on the interpreter.
This patch adds a -Xno-dex-file-fallback option to stop the default behavior.
This can be used two-fold.
First, one can enforce that a runtime only starts with a boot image. A
follow-up patch will ensure that dex2oat (for apps) and patchoat in general
request that mode and close gracefully otherwise.
Second, this can be used for testing and debugging purposes, as it ensures
that compiler failures & aborts are not silently ignored.
Add testing.

Implement a simple count based boot marker.
We write the number of failed boots to the marker and only
prune the dalvik cache if the number of consecutive failed
boots is higher than a predefined threshold.
Note that the code is forgiving of errors related to boot
markers; we continue the boot process even if we're unable
to create / write or flush the boot marker.

Follow up on CL 122665.
We now do the two-step memory protection strategy (first protect the
from space with PROT_READ and later protect it with PROT_NONE) only if
the from space is a rosalloc space (excluding the more common bump
pointer space case). This strengthens the GC verification for the bump
pointer space case as we avoid the case where mutators run while the
from space is PROT_READ rather than PROT_NONE.
Add a command line flag to override the minimum interval for the
hspace compaction for OOM and set it to zero in the gcstress/gcverify
run-tests to run the hspace compaction more frequently in tests.
Fix some comments.

Remove back-door bootclasspath option from Runtime
The 'bootclasspath' option allowed users of the Runtime to load their
own boot class path DexFiles and pass them directly to the Runtime as
an option. This obscures the fact that the Runtime must take ownership
of the boot class path DexFiles.
This change removes the use of the bootclasspath option by dex2oat and
the common runtime tests. For dex2oat, we use the existing
-Xbootclasspath option instead, and introduce a new
-Xbootclasspath-locations option to override the dex locations for the
loaded boot class path dex files. For the common runtime tests, we
simply use -Xbootclasspath.

ART: Compacting ROS/DlMalloc spaces with semispace copy GC
Current semispace copy GC is mainly associated with bump pointer
spaces. Though it squeezes fragmentation most aggressively, an extra
copy is required to re-establish the data in the ROS/DlMalloc space to allow
CMS GCs to happen afterwards. As semispace copy GC is still stop-the-world,
this not only introduces unnecessary overheads but also longer response time.
Response time indicates the time duration between the start of transition
request and the start of transition animation, which may impact the user
experience.
Using semispace copy GC to compact the data in a ROS space to another ROS(or
DlMalloc space to another DlMalloc) space solves this problem. Although it
squeezes less fragmentation, CMS GCs can run immediately after the compaction.
We apply this algorithm in two cases:
1) Right before throwing an OOM if -XX:EnableHSpaceCompactForOOM is passed in
as true.
2) When app is switched to background if the -XX:BackgroundGC option has value
HSpaceCompact.
For case 1), OOMs are significantly delayed in the harmony GC stress test,
with compaction ratio up to 0.87. For case 2), compaction ratio around 0.5 is
observed in both built-in SMS and browser. Similar results have been obtained
on other apps as well.

Add mark compact collector.
The mark compact collector is a 4 phase collection, doing a normal
full mark_sweep, calculating forwarding addresses of objects in the
from space, updating references of objects in the from space, and
moving the objects in the from space.
Support is diabled by default since it needs to have non movable
classes and field arrays. Performance numbers is around 50% as fast.
The main advantage that this has over semispace is that the worst
case memory usage is 50% since we only need one space isntead of two.
TODO: Make field arrays and classes movable. This causes complication
since Object::VisitReferences relies on these, so if we update the
fields of an object but another future object uses this object to
figure out what fields are reference fields it doesn't work.

Use strtod to read a double rather than operator >>
The >> operator doesn't work on the x86_64 build in the emulator. This
works around the issue by using strtod instead.

Switch on implicit null pointer and stack overflow checks.
This switches on the use of implicit checks for null pointers
and stack overflows. These use the SIGSEGV handler in the ART

Handle implicit stack overflow without affecting stack walks
This changes the way in which implicit stack overflows are handled
to satisfy concerns about changes to the stack walk code.
Instead of creating a gap in the stack and checking for it in
the stack walker, use the ManagedStack infrastructure to concoct
an invisible gap that will never be seen by a stack walk.
Also, this uses madvise to tell the kernel that the main stack's
protected region will probably never be accessed, and instead
of using memset to map the pages in, use memcpy to read from
them. This will save 32K on the main stack.
Also adds a 'signals' verbosity level as per a review request.

Enable concurrent sweeping for non-concurrent GC.
Refactored the GarbageCollector to let all of the phases be run by
the collector's RunPhases virtual method. This lets the GC decide
which phases should be concurrent and reduces how much baked in GC
logic resides in GarbageCollector.
Enabled concurrent sweeping in the semi space and non concurrent
mark sweep GCs. Changed the semi-space collector to have a swap semi
spaces boolean which can be changed with a setter.
Fixed tests to pass with GSS collector, there was an error related to
the large object space limit.
Before (EvaluateAndApplyChanges):
GSS paused GC time 7.81s/7.81s, score: 3920
After (EvaluateAndApplyChanges):
GSS paused GC time 6.94s/7.71s, score: 3900
Benchmark score doesn't go up since the GC happens in the allocating
thread. There is a slight reduction in pause times experienced by
other threads (0.8s total).
Added options for pre sweeping GC heap verification and pre sweeping
rosalloc verification.

Implicit null/suspend checks (oat version bump)
This adds the ability to use SEGV signals
to throw NullPointerException exceptions from Java code rather
than having the compiler generate explicit comparisons and
branches. It does this by using sigaction to trap SIGSEGV and when triggered
makes sure it's in compiled code and if so, sets the return
address to the entry point to throw the exception.
It also uses this signal mechanism to determine whether to check
for thread suspension. Instead of the compiler generating calls
to a function to check for threads being suspended, the compiler
will now load indirect via an address in the TLS area. To trigger
a suspend, the contents of this address are changed from something
valid to 0. A SIGSEGV will occur and the handler will check
for a valid instruction pattern before invoking the thread
suspension check code.
If a user program taps SIGSEGV it will prevent our signal handler
working. This will cause a failure in the runtime.
There are two signal handlers at present. You can control them
individually using the flags -implicit-checks: on the runtime
command line. This takes a string parameter, a comma
separated set of strings. Each can be one of:
none switch off
null null pointer checks
suspend suspend checks
all all checks
So to switch only suspend checks on, pass:
-implicit-checks:suspend
There is also -explicit-checks to provide the reverse once
we change the default.
For dalvikvm, pass --runtime-arg -implicit-checks:foo,bar
The default is -implicit-checks:none
There is also a property 'dalvik.vm.implicit_checks' whose value is the same
string as the command option. The default is 'none'. For example to switch on
null checks using the option:
setprop dalvik.vm.implicit_checks null
It only works for ARM right now.
Bumps OAT version number due to change to Thread offsets.
