This is a reland of a441cbfb Disabling cctest/test-compiler/DeepEagerCompilationPeakMemory in stress mode since allocation is no longer deterministic. Original change's description: > [offthread] Move stress-background-compile to compiler.cc > > Make --stress-background-compile a V8 flag rather than a d8 flag, so > that it also tests unittests/cctests. > > Now, with this flag, every top-level script compile (that fulfills a > couple of restrictions) will be both main-thread and background-thread > compiled, taking the result of the background compile. In the future, > we'll probably want to verify that the two results are equivalent. > > One of the necessary changes to allow tests to pass was to introduce a > concept of a "temporary" script (with a temporary script id), which > doesn't get added to the script list. This is to avoid the main-thread > compile part of the stress-test having a debugger-visible side-effect, > e.g. in tests that enumerate scripts. We can't just create new ids for > such scripts, as then script-id expectation files no longer match. > > Bug: chromium:1011762 > Change-Id: I500bbf2cabea762e69aca3dbae247daae71192cb > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2120541 > Commit-Queue: Leszek Swirski <leszeks@chromium.org> > Reviewed-by: Ross McIlroy <rmcilroy@chromium.org> > Cr-Commit-Position: refs/heads/master@{#67332} TBR=rmcilroy@chromium.org Bug: chromium:1011762 Change-Id: I5f9f0eb71caa4829e72b4a6d2824cbebd3698bd5 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2162876Reviewed-by:

Off-thread compilation currently doesn't support adding DebugInfo to a SharedFunctionInfo, so it also doesn't support adding coverage info. For now, disable off-thread finalization entirely when block coverage is enabled. In the future we most likely want to add support for this.

This reverts commit 29c1eab9. Reason for revert: Causes Blink test failures: https://ci.chromium.org/p/v8/builders/ci/V8%20Blink%20Linux/4222 Original change's description: > [builtins] Clean up the use of class_name / ES5 [[Class]] > > Before ES2015, the ES spec had a [[Class]] internal slot for all > objects, which Object.prototype.toString() would use to figure the > returned string. Post-ES2015, the [[Class]] slot was removed in spec for > all objects, with the @@toStringTag well-known symbol the proper way to > change Object.prototype.toString() output. > > At the time, spec-identical handling without the use of [[Class]] was > implemented in V8 for all objects other than API objects, where issues > with the Web IDL spec [1] prevented Blink, and hence V8, to totally > migrate to @@toStringTag. However, since 2016 [2] Blink has been setting > @@toStringTag on API class prototypes to manage the > Object.prototype.toString() output, so the legacy [[Class]] handling in > V8 has not been necessary for the past couple of years. > > This CL removes the remaining legacy [[Class]] handling in > Object.prototype.toString(), JSReceiver::class_name(), and > GetConstructorName(). However, it does not remove the class_name field > in FunctionTemplateInfo, as it is still used for the `name` property of > created functions. > > This CL also cleans up other places in the codebase that still reference > [[Class]]. > > This change should have minimal impact on web-compatibility. For the > change to be observable, a script must do one of the following: > > 1. delete APIConstructor.prototype[Symbol.toStringTag]; > 2. Object.setPrototypeOf(apiObject, somethingElse); > > Before this CL, these changes will not change the apiObject.toString() > output. But after this CL, they will make apiObject.toString() show > "[object Object]" (in the first case) or the @@toStringTag of the other > prototype (in the latter case). > > However, both are deemed unlikely. @@toStringTag is not well-known > feature of JavaScript, nor does it get tampered much on API > constructors. In the second case, setting the prototype of an API object > would effectly render the object useless, as all its methods (including > property getters/setters) would no longer be accessible. > > Currently, @@toStringTag-based API object branding is not yet > implemented by other browsers.

We don't use StatsCounters anymore for heap work, and this particular counter causes issues for OffThreadSpace, as it can trigger a non-thread-safe counter callback. We could instead make this a thread-safe counter, but since it's unused we may as well just remove it entirely.

Introduce an OffThreadTransferHandle (and OffThreadTransferMaybeHandle), which points to a piece of storage known to (and owned by) the OffThreadIsolate. On Publish, the OffThreadIsolate converts this storage stub from a raw pointer to an off-thread object into a main-thread Handle. This allows users of an OffThreadIsolate to not have to worry (as much) about the dance of saving raw object pointers before off-thread finishes and converting those to Handles before it off-thread isolate is published.

Make --stress-background-compile a V8 flag rather than a d8 flag, so that it also tests unittests/cctests. Now, with this flag, every top-level script compile (that fulfills a couple of restrictions) will be both main-thread and background-thread compiled, taking the result of the background compile. In the future, we'll probably want to verify that the two results are equivalent. One of the necessary changes to allow tests to pass was to introduce a concept of a "temporary" script (with a temporary script id), which doesn't get added to the script list. This is to avoid the main-thread compile part of the stress-test having a debugger-visible side-effect, e.g. in tests that enumerate scripts. We can't just create new ids for such scripts, as then script-id expectation files no longer match.

Move the persistent compilation state and Isolate inputs (such as the allocator, shared AST constants, hash seed, logger, etc.) which survives across both parse and compile, out of ParseInfo and into a new UnoptimizedCompileState class. Also add UnoptimizedCompilePerThreadState for per-thread state such as stack limit and RCS. In particular, this new state survives the ParseInfo being destructed, which means it is available after off-thread finalization. This allows a followup to access the PendingCompilationErrorHandler after finalization and report errors on merge.

Before ES2015, the ES spec had a [[Class]] internal slot for all objects, which Object.prototype.toString() would use to figure the returned string. Post-ES2015, the [[Class]] slot was removed in spec for all objects, with the @@toStringTag well-known symbol the proper way to change Object.prototype.toString() output. At the time, spec-identical handling without the use of [[Class]] was implemented in V8 for all objects other than API objects, where issues with the Web IDL spec [1] prevented Blink, and hence V8, to totally migrate to @@toStringTag. However, since 2016 [2] Blink has been setting @@toStringTag on API class prototypes to manage the Object.prototype.toString() output, so the legacy [[Class]] handling in V8 has not been necessary for the past couple of years. This CL removes the remaining legacy [[Class]] handling in Object.prototype.toString(), JSReceiver::class_name(), and GetConstructorName(). However, it does not remove the class_name field in FunctionTemplateInfo, as it is still used for the `name` property of created functions. This CL also cleans up other places in the codebase that still reference [[Class]]. This change should have minimal impact on web-compatibility. For the change to be observable, a script must do one of the following: 1. delete APIConstructor.prototype[Symbol.toStringTag]; 2. Object.setPrototypeOf(apiObject, somethingElse); Before this CL, these changes will not change the apiObject.toString() output. But after this CL, they will make apiObject.toString() show "[object Object]" (in the first case) or the @@toStringTag of the other prototype (in the latter case). However, both are deemed unlikely. @@toStringTag is not well-known feature of JavaScript, nor does it get tampered much on API constructors. In the second case, setting the prototype of an API object would effectly render the object useless, as all its methods (including property getters/setters) would no longer be accessible. Currently, @@toStringTag-based API object branding is not yet implemented by other browsers. This V8 bug in particular has been an impediment to standardizing toString behavior. Fixing this bug will unblock [3] and lead to a better Web IDL spec, and better toString() compatibility for all.

There's no reason for it to be a JSArray; it's an internal data member. We only have a slow version for constructing a FixedArray from an Iterable, but since this is not a performance critical code path, it's fine.
