BasicMemoryChunk flags should only be mutated from the main thread when no concurrent task can access them. For that purpose it is enough to use regular non-atomic flags as they are immutable while the GC is running.

Previously SharedTurboAssembler was a base class for ia32 and x64 TurboAssembler. This made it easy to share code, only if the implementation was the same. In some cases, like ExternalReferenceAsOperand, the implementation defers slightly between the two architectures. We add a new class template SharedTurboAssemblerBase, which derives from SharedTurboAssembler. Using the CRTP pattern, we can call derived classes functions using the template parameter. For any function that is exactly the same, we can declare them in the header and define them in the cc file, instead of inlining them all into the header.

This avoids a benign race in setting the raw pointer inside CTP destructor by not emitting the write at all. The handle is destructed which means that we only need to destroy any backing node but may leave the handle untouched. Drive-by: - Add a few more docs. - Make Clear() thread-safe. - Make assignment of a sentinel pointer thread-safe. - Make assignment of a nullptr thread-safe.

In Blink, WindowProxy may be referred from two diffrent JS wrapper objects during page refresh (same site navigation reusing parts of the DOM). In this intermediate state, the old frame state is not yet reclaimed while the new state is already being added. We would like to only merge nodes when there's a 1:1 relation between C++ and JS objects. Unfortunately, WindowProxy breaks that assumption in that the C++ object doesn't directly point to the wrapper. In addition, merging this case is important as otherwise detachedness would not be propagated to the Window object (JS wrapper) which is the main user of detachedness. The CL allows overriding merged nodes, picking a random merged state during pageload while still resulting in the regular snapshot behavior outside of reloading the same page. The proper fix is addressing chromium:1218404 and only create merged nodes when the back reference points to the same object.

.. from a StackTraceFrameIterator (STFI). This replaces the (incorrect) pattern StackTraceFrameIterator it(isolate); FrameSummary fs = FrameSummary::GetTop(it.javascript_frame()); The STFI has filtering semantics that only iterate over certain JS and Wasm frames. These semantics (e.g. skipping over frames that are not subject to debugging) must be preserved when looking into inlined optimized frames. The new convenience function GetTopValidFrame encapsulates this logic.

As a first step toward generating longer-width SIMD (see design doc), this change adds the ability to emit 256-bit instructions in the x64 assembler. The `YMMRegister` class indicates that a 256-bit instruction should be emitted (versus a 128-bit instruction for `XMMRegister`). This also includes a sample implementation for `vmovdqa` and `vmovdqu` and the encoded bits are checked against known-good output from NASM.

We reduce the number of cases tested to lane_size * len(test_arr), which stills give us very good coverage.

This patchset introduces instrumentation of the memory usage of the datatructures maintained by the CPU profiler. It captures: * The total size of the strings held in StringsStorage for CodeEntries * Estimated size held by CodeMap's entries. The target is to surface that metric through telemetry to get better visibility into the memory profile of CpuProfiler. For now, STL containers overhead is ignored as it is implementation specific.

We are running out of encoding space for opcodes on arm64. This patch merges some wasm simd opcodes of different simd types, encoding the lane size in the instruction code using LaneSizeField instead. This reduces the total number of opcodes on arm64 by 71.
