BUG= R=svenpanne@chromium.org Review URL: https://codereview.chromium.org/23707009 Patch from Marja Hölttä <marja@chromium.org>. git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@16493 ce2b1a6d-e550-0410-aec6-3dcde31c8c00	2013-09-03 07:34:34 +00:00
bmeurer@chromium.org	281de965a4	Import ConditionVariable class. Condition variables are synchronization primitives that can be used to block one or more threads while waiting for condition to become true. Right now we have only semaphores, mutexes and atomic operations for synchronization, which results in quite complex solutions where an implementation using condition variables and mutexes would be straight forward. There's also a performance benefit to condition variables and mutexes vs semaphores, especially on Windows, where semaphores are kernel objects, while mutexes are implemented as fast critical sections, it CAN be beneficial performance-wise to use condition variables instead of semaphores.

adamk@chromium.org	bf42ded40d	This patch implements optimized objectInfo structure which manages the set of observers associated with an object and the changeRecord types which they accept. Observation in the normal case (Object.observe, default accept types, one observer) now allocates fewer objects and unobservation no longer needs to scan and splice an InternalArray -- making the combined speed of observe/unobserve about 200% faster. This patch implements the following optimizations: -objectInfo is initially created without any connected objects or arrays. The first observer is referenced directly by objectInfo, and when a second observer is added, changeObservers converts to a mapping of callbackPriority->observer, which allows for constant time registration/de-registration. -observer.accept and objectInfo.performing are conceptually the same data-structure. This is now directly represented as an abstract "TypeMap" which can later be optimized to be a smi in common cases, (e.g: https://codereview.chromium.org/19269007/). -objectInfo observers are only represented by an object with an accept typeMap if the set of accept types is non-default R=rossberg@chromium.org Review URL: https://codereview.chromium.org/19541010 Patch from Rafael Weinstein <rafaelw@chromium.org>. git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@16343 ce2b1a6d-e550-0410-aec6-3dcde31c8c00	2013-08-26 21:37:21 +00:00

yurys@chromium.org	4db1f475ec	Support higher CPU profiler sampling rate on posix systems New flag is added that allows to specify CPU profiler sampling rate in microseconds as command line argument. It was tested to work fine with 100us interval(currently it is 1ms). Default values are kept the same as in the current implementation. The new implementation is enabled only on POSIX platforms which use signals to collect samples. Other platforms that pause thread being sampled are to follow. SIGPROF signals are now sent on the profiler event processor thread to make sure that the processing thread does fall far behind the sampling. The patch is based on the previous one that was rolled out in r13851. The main difference is that the circular queue is not modified for now. On Linux sampling for CPU profiler is initiated on the profiler event processor thread, other platforms to follow. CPU profiler continues to use SamplingCircularQueue, we will probably replace it with a single sample buffer when Mac and Win ports support profiling on the event processing thread. When --prof option is specified profiling is initiated either on the profiler event processor thread if CPU profiler is on or on the SignalSender thread as it used to be if no CPU profiles are being collected. ProfilerEventsProcessor::ProcessEventsAndDoSample now waits in a tight loop, processing collected samples until sampling interval expires. To save CPU resources I'm planning to change that to use nanosleep as only one sample is expected in the queue at any point.

In this case, the code for DOUBLE_ALIGNMENT uses the scratch2 register, which is aliased to obj_size_reg containing the object_size. Instead of pre-loading the object_size, which is difficult since we are out of registers here, we simply generate a non-empty sequence of add instructions for the addition of the constant object_size (carefully handling possible overflow in each step).

svenpanne@chromium.org	f0305bd83e	Instance-type-related fixes and cleanup. Things got quite a bit out of sync (don't we all love copy-n-paste?): * TypeToString didn't handle SLICED_STRING_TYPE, SLICED_ASCII_STRING_TYPE, FIXED_DOUBLE_ARRAY_TYPE, JS_FUNCTION_PROXY_TYPE and JS_DATE_TYPE. * INSTANCE_TYPE_LIST was missing entries for SLICED_ASCII_STRING_TYPE, JS_SET_TYPE, and JS_MAP_TYPE. To improve this maintenance nightmare a little bit, the missing instance types were added to the INSTANCE_TYPE_LIST macro and this list is now used via our beloved 2nd order macro technique in TypeToString. As a side-effect, the strings returned by TypeToString have a "_TYPE" suffix now, but this doesn't really matter and is a small price to pay for consistency.

palfia@homejinni.com	5021e72675	MIPS: First implementation of allocation elimination in Hydrogen. Port r16098 (328ff5f7) Original commit message: This change implements a simple data-flow analysis pass over captured objects to the existing escape analysis. It tracks the state of values in the Hydrogen graph through CapturedObject marker instructions that are used to construct an appropriate translation for the deoptimizer to be able to materialize these objects again. This can be considered a combination of scalar replacement of loads and stores on captured objects and sinking of unused allocations.

yangguo@chromium.org	8fb95efdda	Improve internal stringifcation for custom Error objects. If an developer attempts to "subclass" Error by running `MyError.prototype = new Error();`, then the internal v8::Message object that's produced and handed off to `window.onerror` handlers is poorly stringified as "[object Object]". This patch adjusts the stringification process for these objects to include not only native Error objects, but also objects that have Error in their prototype chain, and haven't overwritten Error.toString with some custom variant.

rossberg@chromium.org	92bd4d1f2d	I found this working on https://codereview.chromium.org/19541010/ The main problem is that if you called Object.getNotifier(obj) on an object, %SetObserved(object) would never get called on it, and thus it would be unobservable (new test added for this). Additionally, Runtime::SetObserved was asserting obj->IsJSObject() which would fail if called on a proxy. It just happens that our existing test always called getNotifier() before Object.observe on proxies, and thus we never previously attempted to transition the map of a proxy. Both issues are now fixed and properly tested.
