For i64x2.ext_mul and i16x8.ext_mul, we can simply call the macro-assembler functions. For i32x4.ext_mul, the macro-assembler requires that dst == src1 if AVX is not supported, so we add a helper function to do that check, and make sure dst == src1 before calling into macro-assembler. This is the same implementation as x64 (https://crrev.com/c/2603765).

Design doc: https://docs.google.com/document/d/1xkXj94iExFgLWc_OszTNyNGi523ARaKMWPZTeomhI4U A lot has changed since the last patchset! I recommend revisiting this design doc and reading the parts in green. I explain the roadmap for what changes to expect from ETW instrumentation as well as the instrumentation of this particular CL. I'll do my best to answer any further questions anyone has about my particular instrumentation or ETW in general :) --- This is the first of a series of changelists to round out ETW instrumentation for V8. This changelist represents the most minimal change needed to instrument ETW in V8. In particular, it: - defines and registers the ETW provider, - interacts minimally with the rest of V8, by hooking into the existing TracingController::AddTraceEvent function, - is designed with a platform-agnostic layer, so that event tracers for other platforms can be instrumented in teh future. Some notes on instrumentation (aka I copied stuff from the design doc): We make heavy use of the TraceLogging API to log events. It differs from previous methods of emitting ETW events in that it doesn<E2><80><99>t require the overhead of a separate manifest file to keep track of metadata; rather, events using this API are self-descriptive. Here are the five major steps to instrument the TraceLogging API: - Forward declare the provider (from provider-win.h) - Define the provider in a .cc file (from provider-win.cc) - Register the provider (called from v8.cc). - Write events (called from libplatform/tracing-controller.cc) - Unregister the provider (called from v8.cc) At the base, we have an abstract provider class that encapsulates the functionality of an event provider. These are things like registering and unregistering the provider, and the actual event-logging. The provider class is split into provider-win and provider-mac (currently not instantiated) classes, with OS-dependent implementations of the above functions. In particular, the TraceLogging API is used only in provider-win. It is here that we forward declare and define the provider, as well as write ETW events. Finally, there is a v8-provider class that serves as a top-level API and is exposed to the rest of V8. It acts as a wrapper for the platform-specific providers. The .wprp file is needed so that Windows Performance Recorder knows how to capture our events. Some considerations: - Is TracingController::AddTraceEvent the best place from which to write my events? - Is src/libplatform/tracing the best place to put my instrumentation? - Right now, I fail the preupload because of this, which tells me my files are probably not in the best location: You added one or more #includes that violate checkdeps rules. src\init\v8.cc Illegal include: "src/libplatform/tracing/v8-provider.h" Because of "-src/libplatform" from src's include_rules.

The negative implication from --single-threaded to --liftoff was introduced because with --single-threaded, no tier-up to TurboFan is possible, and TurboFan provides faster code and smaller code This CL removes this implication. The reason is that this implication does not only define the default compiler for --single-threaded to TurboFan, and also completely disables the option to use Liftoff instead. By removing the implication, and embedder who uses --single-threaded can decide by themselves if they want to use Liftoff by setting --liftoff, or if they don't want to use Liftoff by setting --no-liftoff.

According to the Torque definition, the type of the 'source' field is 'String|Undefined'. The Factory only allowed to pass a string though, which forced us to set an empty string for wasm scripts. This CL changes the factory to also allow undefined values, which fits slightly better for wasm. The inspector needed a minor change to handle undefined source like an empty string.

Previously the proxies that make up the DebugEvaluate implementation for Wasm frames lived in wasm-js.cc, but that was quite confusing since (a) the rest of the debug support for Wasm lives in wasm-debug.cc (and we intend to eventually unify the DebugEvaluate and Scope objects), and (b) the wasm-js.cc file is explicitly about the WebAssembly JS API that's part of the WebAssembly specification, and the DebugEvaluate proxies aren't part of that.

The wasm-scope-info-liftoff.js and wasm-set-breakpoint-liftoff.js tests were originally testing the Liftoff path (when we still had the Wasm interpreter), and have received some updates along the way. Nowadays the interpreter is going and the non-liftoff versions of these tests don't provide any additional test coverage, but are merely a slightly less updated version of the liftoff test.

Benedikt Meurer authored
The "imports" and "exports" that were exposed on WebAssembly frames via Debug-Evaluate aren't useful for the DWARF C/C++ extension (and likely not for any other language extension), since they only expose static information that's easily available (upfront) by reading the Wasm wire bytes. In fact, there are already standardized functions in the WebAssembly specification, namely `WebAssembly.Module.imports(module)` and `WebAssembly.Module.exports(module)`, which yield static information about the imports and exports of a Wasm module. So instead of exposing special, non-standard "imports" and "exports", we now instead expose both the "instance" and the "module" objects via both the Debug Proxy and the Scope view, and also add internal [[Exports]] and [[Imports]] properties to WasmModuleObject, which under the hood use the standard methods mentioned above.

For JSArrayBuffer instances (which map to both v8::ArrayBuffer and v8::SharedArrayBuffer), we add a couple of synthetic views to its ValueMirror to make it easy for developers to peak into the contents of the JSArrayBuffer. These were previously real properties, but that's just wrong (both intuitively and semantically), and they should instead be internal properties. Drive-by-fix: The [[IsDetached]] internal property should only be shown on actually detached JSArrayBuffer's to reduce visual clutter. And for detached JSArrayBuffers creating views on them throws TypeErrors per specification, so we shouldn't attempt to display views on them.

We accidentally compiled the source for Debug-Evaluate on Wasm frames twice, and used the first script result as outer function info for the second, actual compile (which goes via the `eval` machinery). Also unify DebugEvaluate::Local and DebugEvaluate::WebAssembly, since they are essentially very similar, except for the context.
