While the sampler checked if the sampled thread had the Isolate locked (if locks are being used) under Linux, the check was not done under Windows (or Fuchsia) which meant that in a multi-threading application under Windows, thread locking was not checked making it prone to seg faults and the like as the profiler would be extracting info from a heap in motion. The fix was to move the lock check into CpuSampler and Ticker (--prof) so all OSes would do the correct check. The basic concept is that on all operating systems a CpuProfiler, and so its corresponding CpuCampler, the profiler is tied to a thread. This is not based on first principles or anything, it's simply the way it works in V8, though it is a useful conceit as it makes visualization and interpretation of profile data much easier. To collect a sample on a thread associated with a profiler the thread must be stopped for obvious reasons -- walking the stack of a running thread is a formula for disaster. The mechanism for stopping a thread is OS-specific and is done in sample.cc. There are currently three basic approaches, one for Linux/Unix variants, one for Windows and one for Fuchsia. The approaches vary as to which thread actually collects the sample -- under Linux the sample is actually collected on the (interrupted) sampled thread whereas under Fuchsia/Windows it's on a separate thread. However, in a multi-threaded environment (where Locker is used), it's not sufficient for the sampled thread to be stopped. Because the stack walk involves looking in the Isolate heap, no other thread can be messing with the heap while the sample is collected. The only ways to ensure this would be to either stop all threads whenever collecting a sample, or to ensure that the thread being sampled holds the Isolate lock so prevents other threads from messing with the heap. While there might be something to be said for the "stop all threads" approach, the current approach in V8 is to only stop the sampled thread so, if in a multi-threaded environment, the profiler must check if the thread being sampled holds the Isolate lock. Since this check must be done, independent of which thread the sample is being collected on (since it varies from OS to OS), the approach is to save the thread id of the thread to be profiled/sampled when the CpuSampler is instantiated (on all OSes it is instantiated on the sampled thread) and then check that thread id against the Isolate lock holder thread id before collecting a sample. If it matches, we know sample.cc has stop the sampled thread, one way or another, and we know that no other thread can mess with the heap (since the stopped thread holds the Isolate lock) so it's safe to walk the stack and collect data from the heap so the sample can be taken. It it doesn't match, we can't safely collect the sample so we don't.

The graph assembler calls MergeControlToEnd as part of Unreachable node creation; this causes issues when used inside the GraphReducer framework, since the reducer is not notified by gasm that the end node should be revisited. The (hacky) fix in this CL is to always mark the end node for revisitation after a gasm reduction has taken place.

With conservative stack scanning enabled, a snapshot of the call stack upon entry to GC will be used to determine part of the root-set. When the collector walks the stack, it looks at each value and determines whether it could be a potential on-heap object pointer. However, unlike with Handles, these on-stack pointers aren't guaranteed to point to the start of the object: the compiler may decide hide these pointers, and create interior pointers in C++ frames which the GC doesn't know about. The solution to this is to include an object start bitmap in the header of each page. Each bit in the bitmap represents a word in the page payload which is set when an object is allocated. This means that when the collector finds an arbitrary potential pointer into the page, it can walk backwards through the bitmap until it finds the relevant object's base pointer. To prevent the bitmap becoming stale after compaction, it is rebuilt during object sweeping. This is experimental, and currently only works with inline allocation disabled, and single generational collection.

Even though we provide a --wasm-max-code-space flag (defaulting to {kMaxWasmCodeMB}, we still had checks in place that the actual committed code space is not bigger than that constant. This CL fixes that by always comparing against the value of the flag. This will allow us to specify a code space limit which is larger than the default. This is useful when debugging larger Wasm apps which exceed the limit, but are not meant to be shipped that way. Drive-by: Remove a dead use of the {kMaxWasmCodeMemory} constant.

LoadICParameters already has separate fields for receiver and holder, though, in practice, they were always equal. Moreover, the holder didn't mean holder, but the lookup start object. This CL makes parts of the IC layer reusable for cases where they are not equal, by clarifying whether we're accessing the receiver, the lookup_start_object, or the holder. List of changes: StoreICParameters: - Detached from LoadICParameters, now they are independent classes. LoadICParameters: - Renamed holder to lookup_start_object. TryProbeStubCache: - Renamed receiver to lookup_start_object. LoadIC: LoadIC_BytecodeHandler: LoadIC_NoFeedback: KeyedLoadIC: KeyedLoadICGeneric: KeyedLoadICPolymorphicName: - These won't be reused in the receiver != lookup_start_object case, so added asserts that receiver == lookup_start_object. TryMonomorphicCase: HandlePolymorphicCase: LoadIC_Noninlined: GenericElementLoad: - Renamed receiver_map param to lookup_start_object_map. The callers either assert receiver == lookup_start_object, or read the map from the lookup start object. GenericPropertyLoad: - Renamed receiver param to lookup_start_object. - Renamed receiver_map param to lookup_start_object_map. The callers either assert receiver == lookup_start_object, or read the map from the lookup start object. CallGetterIfAccessor: - Added the holder parameter and used it accordingly.

Schedule is simpler compared to the schedule in blink since it now returns deadlines based on marked bytes instead of time. If marking is ahead of schedule, return the minimum step size. Otherwise, set step size to catch up to schedule (ignoring the time passed while performing the step). No more default initial step size (needed in blink since marking speed was unknown). If estimated schedule is exceeded (marking takes longer than 500ms), the steps will try to mark all remaining objects but would still be capped by the maximum step duration of 2ms.

Starting marking required Creating a Marker and calling StartMarking. StartMarking should always have been called immediately after creating the marker. Since markers are not persisted between GC (a marker exists only while marking is in progress), it makes sense to start marking implicitly when a marker is created. Calling StartMarking in MarkerBase ctor is inadvisable since subclasses might still to initialize fields. Using MarkerFactory instead guarantees that StartMarking is always called immediately after creating a Marker.

This CL fixes the bug related with chunk position initialisation. The bug caused by not subtracting the timeline chunk start time from chunk start time. Additionally, it corrects the offset being used while detecting the chunk location.

In certain situations (especially if the profiler is disabled) it can happen that multiple isolates trigger tier-up at the same time. Each recompilation would then identify the set of functions to recompile and add compilation units for them. This creates lots of redundant compilation, which takes time and can exceed the total wasm code space limit (code would later get garbage-collected, but there is a high peak). This CL fixes that by always finishing a running recompilation before starting a new one. Since typically concurrent recompilations all recompile for the same tier, this would avoid do most compilation only once, and later recompilations can skip most functions. The only redundant compilation that can happen is via compilation units that are still executing while the next recompilation starts, but those should not create too much redundant code.

Port 6da647f5 Original Commit Message: Now that 86 has branched, we can move bitmask into the SIMD MVP, it will not affect the current OT. (We want any OT extension to include bitmask.) Bitmask was accepted into the proposal in https://github.com/WebAssembly/simd/pull/201.
