We use the InvokeParams to pass host-defined options to Invoke. The script should never access them directly and thus we should clear out the argv and argc values.

CodeSpaceMemoryModificationScope should only be used by the main thread and during a safepoint. This adds a check in CodeSpaceMemoryModificationScope. The reason for this is that CodeSpaceMemoryModificationScope is not thread-safe. It assumes that no other thread is modifying code space (either by setting memory permission or adding a new page). This CL also replaces CodeSpaceMemoryModificationScope to CodePageCollectionMemoryModificationScope in a few occurrences, where the former is not needed. This should not hurt performance.

We enable struct.new and array.init initializer expressions in the JS testcase generated by --wasm-fuzzer-gen-test. We needed to make some changes in the WasmInitExpr class, and to implement a new interface for the WasmFullDecoder, which constructs a WasmInitExpr. Changes: - Make WasmInitExpr a ZoneObject. Use a pointer for its operands_ field. This is needed so WasmInitExpr is trivially copiable, and thus usable as a Value type in WasmFullDecoder. - Implement a WasmFullDecoder interface in wasm-fuzzer-common that constructs a WasmInitExpr. Use it to decode initializers in the module generated by the fuzzer. - Change AppendInitExpr to take a WasmInitExpr as argument. - Fix an issue with printing of struct definitions. - Change initializer expression used for structs to struct.new_with_rtt. This is consistent with the currently used structural types.

The wasm serialization format only contains TurboFan code. All other functions are only represented by placeholders. With this CL serialization fails if the serialized module does not contain any TurboFan functions and would therefore consist only of placeholders. This is a defense in depth approach, because ideally serialization only gets triggered when TurboFan code is available. However, in some scenarios like debugging it can happen that modules without TurboFan code get serialized.

Remove the concept of JobId from LazyCompileDispatcher, and make SFIs the canonical id for these jobs. This has several consequences: * We no longer split enqueing a job and registering a SFI with that job. We did this previously because we could not allocate SFIs in the Parser -- now with LocalHeap we can, so we do. * We remove the separate Job vector, and make the SFI IdentityMap hold pointers to Jobs directly. This requires a small amount of extra care to deallocate Jobs when removing them from the map, but it means not having to allocate new global handles for jobs. * The SFI is passed into the BackgroundCompileTask instead of the script, so our task finalization doesn't need the SFI anymore. * We no longer need to iterate ParallelTasks after compiling (to register SFIs), so we can get rid of ParallelTasks entirely and access the dispatcher directly from the parser. There are a few drive-bys since we're touching this code: * Jobs are move to have a "state" variable rather than a collection of bools, for stricter DCHECKing. * There's no longer a set of "currently running" jobs, since this was only used to check if a job is running, we can instead inspect the job's state directly. * s/LazyCompilerDispatcher/LazyCompileDispatcher/g Change-Id: I85e4bd6db108f5e8e7fe2e919c548ce45796dd50 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3259647 Commit-Queue: Leszek Swirski <leszeks@chromium.org> Reviewed-by: -

The old "gc-safe" implementation to get the off-heap type information wasn't quite as gc-safe as it needs to be.

This runtime function behaves like StoreDataPropertyInLiteral, except it can throw, since it's also used for defining public class fields. Unlike the literal use case, class field can end up throwing due to field initializers doing things like freezing the instance.

The goal of the PR is to add to telemetry a metric estimating the space occupied by the codemap retained by a CpuProfiler and its underlying CodeObserver. This change is motivated by the addition of kEagerLogger to CpuProfiler which when enabled let a CpuProfiler build a CodeMap without an active session. This metric will help us understand better the space consumed by a profiler in that scenario and will also help detect memory leaks.

Some post-compile flag setting was unnecessary, since those flags originally came from the SFI they were being set on. Also, DontOptimizeReason was never actually set, so we can remove it entirely.

- Use a StringShape instead of repeatedly querying type. - Add a shortcut for already-flat strings. - Unhandlify where possible (all except SlowFlatten). - Mark String::Flatten and StringShape methods V8_INLINE. - Add a specialized ConsString::IsFlat overload. Drive-by: Various (add const, remove this->, helper methods).

d8 never checked what the actual value of the host-defined options are. We now properly very that the host-defined options is a specific object so we we don't end up accidentally ignoring a wrong options object.
