The test is incompatible with --noenable-sse4-1, which is randomly added by numfuzz (and possibly other fuzzers). The "Flags" from the test files are always passed last and are often used to neuter incompatible flags.

This adds the argument count (as intptr) to the standard frame. StandardFrames are now in the same shape as OptimizedFrames. The argument count in the stack will be used to tear down the arguments when we remove the arguments adaptor frame.

For TypedArray, a fast path is used when using the builtin iterator, and next method has not been overriden. If we use that fast path for JSArray too, the method will be about 200x times faster on a large array. This patch also fixes a bug when a typed array is modified during the mapper execution. In that case, the modification should not be taken into account.

With a recent change, we require WebAssembly code to be tiered up to serialize it, see https://crrev.com/c/2349290. In that CL tests were adjusted to set the --wasm-tier-up flag when serialization was involved. However, the test adjusted in this CL was missing, because this test used the kExprRefNull instruction, which caused a bailout to TurboFan anyways. With recent changes, Liftoff can compile kExprRefNull now, and therefore causes problems.

When enabled with the v8_enable_conservative_stack_scanning flag, a snapshot of the call stack upon entry to GC is used to determine part of the root-set. When the collector walks the stack, it looks at each value and determines whether it could be a potential on-heap object pointer. This is very experimental. For conservative stack scanning to work, direct handles must be implemented.

Change the serialization protocol to ensure that maps are serialized before objects using them. This ensures that as soon as we allocate space for an object, we can immediately write the object's map into that allocation. In the future, this will allow us to make deserialized object visible to the GC. Specifically, this forces map serialization to happen after emitting a kNewObject for an object, but before allocating the space for it. We have to serialize the map after kNewObject because otherwise the map itself would be written into the "current" slot, into which the object is supposed to be deserialized. Objects whose maps are currently being deserialized are considered "pending" -- started, but not yet allocated. The map might point to a pending object (e.g. if an object's constructor points to the object). This is solved by introducing a new concept of forward references, where the field referring to the pending object is serialized as a "pending forward reference" which is "resolved" once the object is allocated. It might also point to itself, in the case of the meta map -- this is simply solved by introducing a new bytecode for the meta map; this cannot be a pending forward reference because the meta map is not yet allocated, so its map slot cannot be registered as pending. Finally, we may need to go to a new chunk after serializing the map; so after the map serialization, we peek to see if there's a next chunk bytecode before the object allocation.

Rewrite the deserializer case macros to look, to formatters, more like a single case value, and clean up some of the repetition to be more explicit, e.g. replace SIXTEEN_CASES(kFoo) impl() with case CASE_REPEAT(kFoo, 16): impl() This should help with auto-formatting issues when modifying the big deserializer switch statement. As a drive-by, also clean up the per-space case macros to use a function rather than a macro for specifying the bytecode, and add helpers for encoding fixed raw data size in the bytecode (similar to the existing helper for fixed repeat counts).

Heap growing estimates when to start incremental gc such that it will finish when we are expecting to finalize (i.e. when an atomic gc would be triggered). There is also a minimum ratio between limit for atomic gc and limit for incremental gc, to guarantee that incremental gc get's some time to run even with the application rarely allocates. This is a continuation of: https://chromium-review.googlesource.com/c/v8/v8/+/2377691 Bug: chromium:1056170 Change-Id: I8c87e98d60b6f8b5748558771a236f15385f7858 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2381454Reviewed-by:

When running 64-bit Windows binaries on macOS using Wine, there is a conflict between macOS's use of GS to point to pthread thread-specific data, and Windows' use of GS to point to the TEB. Apple has reserved some TSD slots for use by Wine to store commonly-used TEB members (such as 0x30, the 'Self' pointer to the TEB). But, other direct GS accesses by Windows programs (such as to 'StackBase') will return macOS pthread data rather than the TEB member. This was causing a V8 unit test to crash on macOS under Wine. Using NtCurrentTeb() gets the 'Self' pointer first, then dereferences it to access the correct 'StackBase', fixing the crash. This turns GetStackStart() from one instruction into two. Chrome (http://crrev.com/c/2380425) and Crashpad also use NtCurrentTeb(). The 32-bit change isn't needed, but is just for consistency.
