Currently, neither IsSharedCrossOrigin nor IsOpaque is set for an empty script. Hence an exception thrown from it (e.g., an exception thrown from native promise implementation) is treated as an error with blink::kNotSharableCrossOrigin. On the other hand, as the script is empty, there is no meaningful URL attached, which means the ExecutionContext's URL is used as the script's name in blink::SourceLocation::FromMessage. In other words, it works virtually as same as blink::kSharableCrossOrigin corresponding to ScriptOriginOptions with IsSharedCrossOrigin set and IsOpaque unset. With this CL, a ScriptOriginOptions with IsSharedCrossOrigin is set and IsOpaque is not set is attached to the empty script, as a preliminary step to deprecate kNotSharableCrossOrigin.

This CL implements a generic baseline version of Array.p.unshift in Torque, enabling us to remove the JS fall-back. The elements-accessor fast-path is still used, but the check whether to use it is also moved to Torque. Support for sparse JSArrays is removed. Drive-by change: Small refactoring in builtins-array that will get extended to other array builtins in a follow-up CL.

Allow mocking the limits for ArrayBuffer allocation to simulate operating system OOM. Fixes: - Ensure OS limit > hard limit for external memory. This is necessary as any processing below the hard limit is opportunistic. E.g. a running sweeper may stall the current marking (GC) round. - Immediately process AB allocations when under memory pressure. Otherwise, the allocations may be stuck in a stalled task. Freeing them upon adding them to the collector still enables parallelism if possible. This reverts commit f3ad6cdb.

This switches on a restricted register allocation for all CSA-generated builtins on ia32, which treats the kRootRegister (=ebx) as unallocatable. A few builtins are explicitly excluded. These still need to be fixed in follow-up CLs. But I'd like to bake this in now to ensure we don't add more code that cannot handle restricted allocation. All of this is still behind the (disabled-by-default on ia32) v8_embedded_builtins configuration.

V8 does not require the embedder to open a HandleScope before executing a v8::Task. However, d8 does open such a HandleScope. Because of that HandleScope we repeatedly found missing HandleScopes only in Chrome tests and not in d8 tests. The same is true for the context, which is not set when Chrome calls a v8::Task. With this CL we create a SealHandleScope around the execution of a v8::Task, and we set the context to nullptr, so that d8 matches Chrome better. Ideally d8 would not open a HandleScope in the first place, and would not set a context. Both make d8 behave different than Chrome and thereby may hide bugs from our testing infrastructure. However, the implementation of the InspectorClient requires them. I think the SealHandleScope and resetting the context is a good workaround at the moment. Yang, do you know if we can get rid of the context there in the long run?

This is a reland of 1c48d52b. It turned out that IterableToList doesn't always behave according to the ES operation with the same name. Specifically, it allows holey arrays to take its fast path, which produces an output array with holes where actually "undefined" elements should appear. This CL changes the version of IterableToList that is used for spreads (IterableToListWithSymbolLookup) such that holey arrays take the slow path. It also includes tests for such situations. Original change's description: > [interpreter] Add bytecode for leading array spreads. > > This CL improves the performance of creating [...a, b] or [...a]. > If the array literal has a leading spread, this CL emits the bytecode > [CreateArrayFromIterable] to create the literal.
