Also OS::Sleep(interval_) is used to pause sampling thread on all platforms. It makes no sense to send signal once 900mks to compensate 100mks delay on signal delivery as the signals would be delivered once 900mks.

Allocator does not backtrack thus during allocation we must not create an unhandled live range which starts before the start of the current live range. If such range is added to the list of unhandled it might see an inconsistent state of active/inactive live-ranges as they are retired to handled as soon as start of the current live range is larger than their end. Add assertion to catch this kind of bugs early.

Renamed SignalSender to SamplerThread to match platforms that don't support signal sending. Cygwin and Windows implementations are almost identical. Mac OS X uses different API to suspend thread but apart from that it is very similar to Windows implenenation.

This is a first step to having profiler sampler implementation in one file with platform capabilities guarded with #ifdef. Otherwise we have very similar implementations scattered over platform-*.cc files which makes it hard to see differences and make changes. The next steps will be to merge win32, Mac OS X and Cygwin implementations into sampler.cc They suspend profiled thread instead of sending a signal but apart from that the logic is pretty much the same. Then I'm going to move sampler-related code from log.* into sampler.* BUG=None Review URL: https://codereview.chromium.org/13852005 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@14265 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

presubmit.py tried to execute cpplint.py directly, but in Windows it's the shell that connects that to the python binary so the execution (subprocess.Popen) needs to be told how to find python. An alternative would be to call subprocess.Popen with shell=True but this is less dangerous.

In this patch, we added the JIT code event handler for Vtune. Most of the code is in the folder src/third_party/vtune. Two APIs are added in include/v8.h to get the requirement info from V8. We add the v8_enable_vtunejit parameter for GYP to enable these Vtune code compilation. vTune::InitilizeVtuneForV8() is invoked in the embedder of V8 to make sure it's invokded if vtune support is enabled.

Assuming that the value on top of stack is return address for a frameless invocation is error-prone. Corresponding logic was removed from profile-generator.cc in r14205 (see https://code.google.com/p/v8/source/diff?spec=svn14205&r=14205&format=side&path=/branches/bleeding_edge/src/profile-generator.cc) and now it is time to remove it from the tick processor. Since the tos is not used anymore by profiler it is also removed from TickSample.

This adds support to the stack guard to trigger a full deoptimization of all optimized code when the GC kicks into high promotion mode. Global pretenuring decisions in optimized code can then be based on the high promotion mode.

When defining an indexed property on an Array object, the object's length property should (perhaps) be updated. This was done for any property for which ToUInt32(name) == ToNumber(name) was true, meaning any property name that, when converted to a number, was an integer in the range [0, 2^32). The detection should be more strict; an indexed property is one for which ToString(ToUInt32(name)) == name is true only.

Port r14230 (76c22097) Original commit message: Native method invocation from the arm/simulator-arm.cc previously made non-portable assumptions about calling conventions. This was okay for 32-bit stack-based machines, where by-value structs are automatically materialized on the stack, and where both int and double parameters could be passed on the stack. However they are not okay for x86-64, which has an elaborate scheme for passing parameters in registers. This CL replaces the previous non-portable code paths with portable code, using call-sites that accurately match the prototype of the callee.
