Previously, compiling with perfetto would add 2.3 MiB to the d8 release binary. With this change it's 472 KiB. This is because trace:lite pulls in many more compiled proto classes than we need, e.g. a bunch of stuff under ftrace/ which is only used on Android. Chrome uses a 'mirror proto' ChromeTrackPacket to only provide compiled protos for the types of packets it will actually see, which on non-android devices does not include anything under ftrace/. We use the same trick here in the JSON consumer.

The read_only_object_cache call cannot return a vector when it is backed by the embedded heap, so this adds a few methods to abstract this away. ExtendReadOnlyObjectCache will eventually have a check to reject adding objects to the embedded read-only object cache. Prior to this change the read-only object cache would only be extended conditionally if needed. Since it started out empty it was always extended, so this removes this logic.

Andreas Haas authored
ASAN on Windows uses exceptions to manage its shadow memory. However, this behavior can conflict with WebAssembly trap handler, because WebAssembly trap handler are executed before the ASAN exception handler. For some WebAssembly instructions we do not generate assembly code but call to C functions instead. Since these functions are very simple, we do not want to reset the thread-in-wasm flag before calling them. However, when these functions trigger the ASAN exceptions, the thread-in-wasm flag gets out-of-sync. This happened for the memory_fill_wrapper function. Originally we thought that it's sufficient to just mark the function with DISABLE_ASAN. However, this is not enough because clang compiles the function to use memset, and memset gets replaced by ASAN with asan_memset. Therefore I decided now that just for sanitizer builds on Windows, we reset the thread-in-wasm flag in memory_fill_wrapper. This is not ideal because it's test-specific code within production code. However, the alternatives also don't sound convincing. Alternatives would be: * Resetting the thread-in-wasm flag whenever we call a c-function - This would be unnecessary performance overhead for production code just to make a test work. * Configure ASAN to not change memset. - This would weaken ASAN also for other cases. * Disable ASAN for trap handlers, or trap handlers in ASAN builds. - This would reduce test coverage.

The invariant is that Map::bit_field2 shouldn't change, and the IsInRetainedMapListBit apparently changes when the map is held weakly from optimized code. This causes TurboFan compilations to change the Map::Hash() result, which in turn causes lookups on the normalized map cache to miss (and maybe other bad consequences). With this change we swap Map::IsInRetainedMapListBit (previously in bit_field2) and Map::HasHiddenPrototypeBit (previously in bit_field3) to address this problem.

COMPLETE events are being deprecated and don't work well with perfetto because we can't give out a handle into the buffer like we used to so that the caller can update the existing event with the duration. BEGIN/END pairs should be used instead to add two separate trace events to the buffer which can be associated with one another by the trace processor e.g. the trace viewer UI.

These were leftover in another directory and can be incorporated into our standard benchmark runner. We already had some Array slice cases in js-perf-test so just add some of the important cases from the other directory to the existing implementation.

We disabled the `delete` optimization, where `delete` on a fast-mode object goes back in the transition tree, because that optimization didn't pay attention to constant field tracking. This change now does the proper fix, which is to invalidate the constness and properly deoptimize all code that depends on it. Drive-by-fix: Handlify the DeleteObjectPropertyFast helper.

If speculation is disallowed, this change lets us still do the optimization if (a) the maps were already reliable or (b) we are able to take stability dependencies.
