700a402244a1a423da4f3ba8032459f4b65fa18f 20-May-2014 Ian Rogers <irogers@google.com> Now we have a proper C++ library, use std::unique_ptr.

Also remove the Android.libcxx.mk and other bits of stlport compatibility
mechanics.

eb8167a4f4d27fce0530f6724ab8032610cd146b 08-May-2014 Mathieu Chartier <mathieuc@google.com> Add Handle/HandleScope and delete SirtRef.

Delete SirtRef and replaced it with Handle. Handles are value types
which wrap around StackReference*.

Renamed StackIndirectReferenceTable to HandleScope.

Added a scoped handle wrapper which wraps around an Object** and
restores it in its destructor.

Renamed Handle::get -> Get.

719d1a33f6569864f529e5a3fff59e7bca97aad0 06-Mar-2014 Ian Rogers <irogers@google.com> Enable annotalysis on clang ART builds.

Fix clang build errors aswell as restructure locking/mutex code for correct
thread safety analysis support.
Reorder make dependencies so that host builds build first as they should
provide better compilation errors than target.
Remove host's use of -fno-omit-frame-pointer as it has no value with correct
use of CFI, which we should have.

bcd5e9daecad39f0dab3246808b4835caec29ea6 13-Nov-2013 Mathieu Chartier <mathieuc@google.com> Manually manage thread pool stacks.

We now allocate the thread pool worker stack using a MemMap. This
enables us to name the maps so that we get more descriptive output
for debugging leaks.

Appears to fix the mips build 5/5 successful clean-oat and builds.
This is probably since glibc caches up to 40 MB of thread stacks
before releasing them.

2775ee4f82dff260663ca16adddc0b15327aaa42 21-Aug-2013 Mathieu Chartier <mathieuc@google.com> Add more runtime options.

Changed HeapGCThreads to be split into two different options:
-XX:ParallelGCThreads: Which specifies how many threads the GC may
use when the mutators are suspended.

-XX:ConcGCThreads: Which specifies how many threads the GC may use
when the mutators are running.

Added runtime options to specify long pause / long GC thresholds:
-XX:LongPauseThreshold (default 5ms)
-XX:LongGCThreshold (default 100ms)
These thresholds were previously constants, but are now runtime
options. If we exceed either of the thresholds, we print the GC
message.

Added a new runtime option: -XX:IgnoreMaxFootprint which makes it
that the GC only does GC when the number of bytes allocated hits
the growth limit. This causes GC to occur much less frequently and
can be useful to measure how much of an impact GC has on performance.

Changed the GC behaviour to use only one thread when we do not care
about pauses to prevent jank that can be caused by 2 simultaneous GC
on different processes fighting for CPU time.

Added thread pool functionality for changing the maximum number of
active workers.

Fixed an accounting error where we didn't count large objects in the
total freed.

Needed to update cpplint to handle const auto.

Fixed a few cpplint errors that were being missed before.

Replaced most of the TODO c++0x with ranged based loops. Loops which
do not have a descriptive container name have a concrete type instead
of auto.

The runtime, compiler, dex2oat, and oatdump now are in seperate trees
to prevent dependency creep. They can now be individually built
without rebuilding the rest of the art projects. dalvikvm and jdwpspy
were already this way. Builds in the art directory should behave as
before, building everything including tests.
