This change turns the previously used XOR-based type checks for external pointers into AND-based type checks. With those, the type tag is ORed into the top bits of an external pointer when it is written, and the type check performed on every load is done by ANDing the value with the inverted tag. This will later allow type checking and masking off the GC marking bits of external pointers in a single operation.

Torque-generated relaxed/acquire/release accessors now expect an additional Tag argument to be more consistent with handwritten accessors. Torque's annotations are renamed from @relaxedRead, @relaxedWrite, @acquireRead and @releaseWrite to @cppRelaxedLoad, @cppRelaxedStore, @cppAcquireLoad and @cppReleaseStore, repesectively. This renaming shall better reflect the fact that those annotations just generate corresponding synchronization on the generated C++ accessors (not CSA code) and be more consistent with the C++ side of things where "Load" and "Store" is used instead of "Read" and "Write". This CL uses these new annotations on a few fields in DebugInfo and FunctionTemplateInfo to have Torque generate accessors automatically.

Resetting the flag in the scope desctructor causes concurrent access to the flag value, triggering a TSAN failure when --stress-concurrent-inlining is on. The behaviour of the stress flag was changed in crrev.com/c/2824440 to improve test coverage, so this CL replaces the scope usage with simple flag assignment.

This is the 1st CL in a series of CLs with the goal to significantly reduce the number of includes in torque-generated files to reduce the build time of Torque's output. So far, all torque-generated builtins included all (197) other builtins generated by Torque. This CL adds tracking of definition locations to Torque's ImplementationVisitor that enables it to only include those builtins that are actually needed for compilation. This change reduces the number of includes for the majority of builtins by 150-180 files.

This reland patch: https://chromium-review.googlesource.com/c/v8/v8/+/2867473 (See patchset 1) The problem was blink injecting interceptor into the window object. It observes "observation" and "mutations" on this object. When it happens to the initial empty document, the IPC DidAccessInitialDocument() is sent and modify the state of the browser process. Causing two tests to fail. The diff (See patchset 1..2) includes: 1. Use JSObject::HasRealNamedProperty instead of JsObject::HasProperty. This skips the interceptor and do not walk the prototype chain. 2. Invert JSObject::HasRealNamedProperty() with IsSharedArrayBufferConstructorEnabled(), just in case. This avoid observing the object when not needed. Original patch description: --- This change makes it possible to enable SharedArrayBuffer per Context, controlling whether it should be enabled or not with a callback. The previous implementation of the reverse origin trial for SharedArrayBuffer was broken, since the feature could only be enabled globally per process, and only if the feature flag is set early enough in the v8 initialization. This does not play well with how origin trials work. The implementation is similar to the callbacks that already exist for the origin trials for WebAssembly simd and exceptions. SharedArrayBuffer is still controlled by the flag harmony_sharedarraybuffer. If that flag is disabled, then SharedArrayBuffer is disabled unconditionally. On top of that, this CL introduces a new flag for enabling SharedArrayBuffer per context. If that flag is set, a callback is used to determine whether SharedArrayBuffer should be enabled. Note that this only controls whether the SharedArrayBuffer constructor should be exposed on the global object or not. It is always possible to construct a SharedArrayBuffer using new WebAssembly.Memory({ shared:true, initial:0, maximum:0 }).buffer.constructor; There are few things which I do not like of this approach, but I did not have better ideas: 1. The complex logic of dobule flag + callback. However, this seemed the best way to me to not break embedders which rely on that flag being enabled by default. 2. The fact that what actually matters is just whether the callback returns `true` once. It would be good to check that the callback gives a consistent return value, or to provide a better API that cannot be missunderstood.

To enforce W^X for the WebAssembly code space, we want to explore using Intel memory protection keys for userspace, also known as MPK, PKEYs, or PKU. Instead of flipping page protection flags with mprotect (which incurs a high syscall overhead; and which switches flags for the whole process), with PKU we associate a key with each page once and then change the permissions of that key with a fast thread-local register write. That is, this gives both finger-grained permissions (per-thread) and more performance. This CL is starts experimenting with PKUs by (1) adding a flag to turn on prototype PKU support; and if set to true (2) allocates a protection key once per {WasmCodeManager} in x64 Linux systems. This is a partial reland of https://crrev.com/c/2850932, which was reverted due to an added histogram failing Chromium integration. Since the histogram (to record PKU support) is independent of the functionality in this CL, we split it out into its own CL (to come).

This is a reland of b271648e Unfortunately the test can still throw a fatal error, since there are other possible paths for OOM.

'override' implies 'virtual', thus 'virtual' should be skipped. R=mlippautz@chromium.org Bug: v8:11717 Change-Id: If5e9c2aeec85fcf0832f9712b6e09752c4d2c2d3 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2878737Reviewed-by:

The application may itself change ASAN poisoning which conflicts with the memset() right before poisoning memory. This is relevant for destructors but also when invoking Resize() on an object that uses ASAN container annotations. Annotations are hard to adjust for the embedder as it is not clear upfront whether the call will succeed.

The DCHECK seems to fail with MSVC on x86 builds. This CL disables this DCHECK when map packing isn't enabled until we have a proper fix. Bug: v8:11748, v8:11624 Change-Id: Iec98d161c5cd2b6a910c29287b54c8e3de017e83 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2878735Reviewed-by:

This CL changes the accounting of array buffers, such that Detach deducts the backing store immediately. Previously this was corrected in the next GC cycle. Not updating backing_store_bytes_ immediately could cause an overflow in WasmMemoryObject::Grow. Grow first detaches the backing store from the old JSArrayBuffer and then attaches it to a new one. This results in the backing store being accounted twice temporarily, this could cause overflows on 32-bit systems.
