Memory access offsets are unsigned. Sign-extending them incorrectly treats some large offsets as negative numbers and results in out-of-bounds errors for in-bounds accesses. This caused a failure in test/mjsunit/wasm/huge-memory.js for arm64, and for x64 with --nowasm_trap_handler.

Previously these would silently fail unless the caller checked the .error property of the return value. There are no tests that check iteractions with non-existent methods so this should always be an error at the test runner level, rather than relying on clients to check the error. 1. Fix the tests that accidentally call methods that don't exist. 2. Change the test runner so that it prints an error and ends the test. 3. Add a test that the test runner does #2.

The change at https://chromium-review.googlesource.com/c/v8/v8/+/1993971 introduced some new exports, but it appears the wrong macro was used for the component being built (V8_BASE_EXPORT rather than V8_EXPORT_PRIVATE) This breaks DLL builds (at least on MSVC, which I just fixed via https://chromium-review.googlesource.com/c/v8/v8/+/1996157).

Add a cctest that contains a function with a SIMD parameter, and calls that function. This will exercise two cases in Liftoff which involves preparing to call the function, and processing the SIMD parameters of the function. The tricky case here is ARM, which requires an FP pair. Most of the logic added is to check the RegClass/type and construct the right type of LiftoffRegister to use. As a drive-by, added SIMD case to the various backends' Move implementation. This is not exercised by the test case, requires more complicated function setup.

This makes Liftoff inspection (scope reporting) also use the decoded names of locals, which are now stored in a C++ data structure (see https://crrev.com/c/2002541). The call to {SetOwnPropertyIgnoreAttributes} had to be replaced by a proper lookup first, to handle integer names and duplicate names correctly. The test already covered these cases. The test was extended by another unnamed local to also test the generation of default names in case no name is provided.

TimeTicks cannot convert to other timeunits, only TimeDelta can do that. Chrome's version of TimeBase introduced a `since_origin` helper that essentially converts a TimeTicks object in to a TimeDelta with the corresponding duration. This CL ports that helper to V8 and cleans up a couple of places where we used `timestamp - 0` to convert a TimeTicks object to a TimeDelta.

We were decoding the names of locals into a C++ data structure, and then generated a FixedArray out of that, stored in the on-heap WasmDebugInfo. In order to support name lookup for debugging with Liftoff, where no WasmDebugInfo will be present, this CL refactors the C++ data structure to allow direct lookups and stores it in the C++ DebugInfo structure. With this CL, the names are still only used from the old interpreter-based debugging path. A follow-up CL will then also use it from Liftoff.

When buildin an array boilerplate description, we currently walk the array literal as if it had tagged pointers, and post-hoc copy it to a FixedDoubleArray if it had double elements kind. Now, we calculate the elements kind during the InitDepthAndFlags walk, and if the elements kind is Double, we allocate a FixedDoubleArray to start with, and convert the elements of the array literal directly to unboxed doubles in the array.

Add support for internalizing an AstValueFactory using the off-thread factory. Includes adding ConsString support to OffThreadFactory. This introduces a Handle union wrapper, which is used in locations that can store a Handle or an OffThreadHandle. This is used in this patch for the internalized "string" field of AST strings, and will be able to be used for other similar fields in other classes (e.g. the ScopeInfo handle in Scope, object boilerplate descriptor handles, the inferred name handle on FunctionLiterals, etc.). It has a Factory-templated getter which returns the appropriate handle for the factory, and a debug-only tag to make sure the right getter is used at runtime. This union wrapper currently decomposes implicitly to a Handle if the getter is not called, to minimise code changes, but this implicit conversion will likely be removed for clarity.

When an overall timeout is reached, swarming sends a SIGTERM to terminate the test runner. The test runner has a signal handler on the main process to terminate all workers gracefully. Additionally, every worker process installs a signal handler for terminating ongoing tests wrapped by command.Command. Also, command.Command is used on the main process to list tests for cctest and gtest executables, which led to overriding the test runner's main signal handler. This CL disables using signal handlers in commands by default and only explicitly enables it in safe source locations.

Function calls can push arguments onto the stack. The consumed stack slots are not considered by the function-entry stack check, since initial frame setup only reserves space for local slots, not call arguments. This CL adds such logic by tracking the maximum pushed argument count during instruction selection, and adding these slots to the (existing) stack check offset logic in code generation.
