1) Computed property keys (esp functions in them) shouldn't be inside the object literal scope. 2) I was using an imprecise "maybe uses super" and storing it to preparse data. This won't fly, since it pollutes sister scopes and leads to confusion wrt whether an object literal needs a home object or not. Made it precise (mostly cancelling changes in the original CL). 3) PreParser::NewSuperPropertyReference was creating a VariableProxy for this_function (which made it used) -> inconsistent scopes between parsing and preparsing. 4) MultipleEntryBlockContextScope was messing up the accumulator Original: https://chromium-review.googlesource.com/c/v8/v8/+/2563275 This saves memory (the home object doesn't need to be stored for each method, but only once per class) and hopefully makes the home object a constant in the optimized code.

On arm64, Windows Performance Recorder gets confused by the fact that fp in Builtins_JSEntry doesn't point to the saved {fp, lr} pair for the caller frame. The expected usage of fp is documented in [1]: The frame pointer (x29) is required for compatibility with fast stack walking used by ETW and other services. It must point to the previous {x29, x30} pair on the stack. In slightly more detail, the Windows function RtlWalkFrameChain is responsible for generating stack traces during profiling with Windows Performance Recorder, and that function relies on the rule quoted above. Notably, it does not make any effort to read the unwinding data that one could obtain with RtlLookupFunctionEntry. Stack walks using that data, such as those performed by WinDbg and the cctest StackUnwindingWin64, work fine. It would be convenient if we could use fp in a more standard way during JSEntry so that Windows profiling tools work correctly. (We can also reduce JSEntry by two instructions in doing so.) Both arm and arm64 currently put a -1 value on the stack at the location that fp points to. This could prevent accidental access during the epilog of JSEntry, where fp might be zero. However, we believe that this protection is no longer necessary, and any bug that causes a read from fp during the end of JSEntry would cause various CQ failures.

The test was explicitly tiering up or down a module, without respecting other isolates. Thus it was failing in multi-isolate mode. This CL removes two runtime functions which do not make sense in a multi-isolate setting (and were only used in this one test), and replaces them with runtime functions that mimic what enabling/disabling the debugger domain does: As long as there is at least one isolate which needs modules to be tiered down, we keep them tiered down.

This was originally proposed by yangguo@ on the original CL that introduced this, but back then it looked easier to put the map cache onto the global object than on the native context. However it turns out that this is indeed quite strange and also not necessarily supported (we got crashes from the wild indicating that the `Object::GetProperty()` might fail on the global object). So this CL simplifies the original design and just puts the map cache onto the native context like with do with other context specific maps.

The inspector fuzzer is terminating the isolate after two seconds. At this point, we can be in pretty much any state, and any further JS execution would fail. This CL fixes an issue where we got the termination signal when creating a context for a regexp (while installing extensions). There might be more places that need fixing, but with this CL the linked issue does not reproduce locally any more, so it's a step forward.

This CL extends the smarter function-entry stack check logic (see v8:9534) to OSR'd code. These smarter stack checks prevent overflowing the stack during deoptimization. The challenge for both function-entry (FE) and OSR-entry (OE) stack checks is that there is no dedicated physical StackCheck to deoptimize into. For more context: the physical StackCheck bytecode was removed in crrev.com/c/1914218. FE stack checks solve this by using a marker bailout id to signify a deopt bytecode offset before the first bytecode. In this CL, OE stack checks take a similar approach by using the OSR'd loop's JumpLoop bytecode, which is conceptually immediately before the OSR'd loop header. When a stack overflow at an OE stack check occurs: %StackGuard may cause a lazy deopt on return to the optimized OSR code, causing re-execution of the JumpLoop handler in the InterpreterEnterBytecodeAdvance builtin, ultimately continuing execution the interpreter at the first bytecode of the OSR'd loop header.

When in postmortem debugging mode, the overall code structure would look similar with some difference: 1. Instead of passing an Isolate* everywhere, we pass a MemoryAccessor. 2. Instead of runtime class names like String, we use uintptr_t 3. When loading data from objects, instead of TaggedField<T>::load or Object::ReadField (which read from the current process), we use the MemoryAccessor and read data from the debuggee process. 4. Return values should be wrapped in the Value struct. Implement the debug accessors for complex length expressions and add test for such class (SmallOrderedHashSet).

This is a reland of 860fcb1b - Disabled the tests for this feature in V8-lite mode (the original change broke V8-lite tests) - Also modified test console-profile-wasm.js that was brittle with this change because it assumed that there was always a JS-to-Wasm wrapper but this is not the case when the TurboFan compilation completes before the Liftoff-compiled code starts to run. More changes in Patchset 8: - Moved inlining of the "JSToWasm Wrapper" away from simplified-lowering, into a new phase, wasm-inlining that reuses the JSInliner reducer. The doc https://docs.google.com/document/d/1mXxYnYN77tK-R1JOVo6tFG3jNpMzfueQN1Zp5h3r9aM/edit# describes the new logic. - Fixed a couple of small issues in wasm_compiler.cc to make sure that the graph "JSToWasm Wrapper" subgraph has a valid Control chain; this should solve the problem we had inlining the calls in functions that can throw exception.

For asynchronous compilation, the beginning and end of compilation are marked with different trace events. To allow to connect these events, a compilation id is added to the start and end events. Note that the compilation id is not added to all trace events to avoid bloating traces. Ids may be added later to these events if necessary.

Adds a v8-gn.h file containing defines that are used in the externally-visible headers files like v8.h. This must be included by include/v8config.h which includes it if the GN flag v8_generate_external_defines_header is on. (Currently off by default). To enable the v8config.h file to be included without the other v8 headers (as required by cppgc), this moves it into its own header set which sets up the include path correctly. Also updates some headers to ensure v8config.h is included before using externally-visible defines.
