Custom platform implementations which do not run all foreground tasks before shutting down an isolate could trigger a DCHECK (see linked issue). This was introduced in https://crrev.com/c/2578980, but the bug does not trigger in the default platform implementation, hence went unnoticed. Since it's only a spurious DCHECK error without security implications, I decided against a test with a custom platform implementation to reproduce the bug.

Design doc: https://docs.google.com/document/d/1g_NExMT78II_KnIYNa9MvyPYIj23qAiFUEsyemY5KRk/edit This change adds 16 new interpreter opcodes, kStar0 through kStar15, so that we can use a single byte to represent the common operation of storing to a low-numbered register. This generally reduces the quantity of bytecode generated on web sites by 8-9%. In order to not degrade speed, a couple of other changes are required: The existing lookahead logic to check for Star after certain other bytecode handlers is updated to check for these new short Star codes instead. Furthermore, that lookahead logic is updated to contain its own copy of the dispatch jump rather than merging control flow with the lookahead-failed case, to improve branch prediction. A bunch of constants use bytecode size in bytes as a proxy for the size or complexity of a function, and are adjusted downward proportionally to the decrease in generated bytecode size. Other small drive-by fix: update generate-bytecode-expectations to emit \n instead of \r\n on Windows.

Change the interpreter tracing functions to be generic unoptimized code tracing functions. The type of the code is now inferred from the frame, rather than passed in. Also expands the set of gn flags to explicitly enable unoptimized tracing, with a helper gn flags for enabling it for Ignition and for baseline (both just set unoptimized tracing to be enabled for now, we could split this up in the future though), and V8 flags separate tracing Ignition and tracing baseline.

On-heap hash maps in blink are limited to Member types and non-traceable types. The only exception to that is TraceWrapperV8Reference. Thus ephemerons can have non-gced traceable values. This values should not be pushed to the marking worklist since we expect everything in the worklist to be marked and not in construction (but these values don't have an object header). Instead, when getting a non-gced value we should immediately trace it. This is only relevant to ephemerons. Any other case would go through Trace(const T&) that dispatches to the TraceTrait. Blink has 1 use case of HeahHashMap from WeakMember<ScriptWrappable> to TraceWrapperV8Reference.

For stack traces, especially all stack traces exposed via the Inspector (i.e. for the purpose of async stack traces), JSFunction::GetDebugName() is still a bottleneck, even after the removal of "displayName" support. As outlined in https://bit.ly/devtools-function-displayName-removal a follow-up optimization here would be to improve the performance of the "name" lookup. Previously, it'd always use the LookupIterator combined with JSReceiver::GetDataProperty(), which in the common case would find the "name" property and the return undefined, since it doesn't invoke getters on AccessorInfos, and eventually fall through to the actual logic in SharedFunctionInfo::DebugName(). Now we had a similar situation with Function.prototype.bind(), which also needs to lookup "name" on regular function objects quite often, and what we implemented there is to just look into the DescriptorArray of the incoming function object and see if the entry for the "name" descriptor is still untouched (key is "name" and value is an AccessorInfo), and if so completely bypass the slow-path lookup via the LookupIterator. With this CL (and the optimization in https://crrev.com/c/2695386), the cost of symbolization is now significantly lower than the cost of the actual stack trace capturing, for the async stack traces in the example from https://crbug.com/1077657 as indicated by the perf profile below: ``` - 26.03% v8_inspector::AsyncStackTrace::capture + 17.34% v8::StackTrace::CurrentStackTrace - 7.27% v8_inspector::(anonymous namespace)::toFramesVector - 7.18% v8_inspector::V8Debugger::symbolize - 6.27% v8_inspector::StackFrame::StackFrame + 2.52% v8_inspector::toProtocolString + 1.88% v8::internal::StackFrameInfo::GetLineNumber 0.78% operator new[] 0.55% operator new[] ``` Bug: chromium:1077657, v8:8742, chromium:1069425, chromium:1177685 Change-Id: I38f23816295f4381f5109cc78e4856dc0b67b097 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2695593 Commit-Queue: Benedikt Meurer <bmeurer@chromium.org> Auto-Submit: Benedikt Meurer <bmeurer@chromium.org> Reviewed-by:

Previously we had cached the source position information on JSStackFrame (C++) objects and reused that between calls to GetLineNumber() and GetColumnNumber(). The refactoring in https://crrev.com/eed0d27c2f774b3adbc85d0a5fb30a8cf0f018a8 effectively removed that cache, while still making things faster though. This CL puts back the caching on the StackFrameInfo objects by reusing the `offset` slot to store the computed source position (as indicated by a bit in the `flags`). For promise combinator async frames, the bit is always set and the `offset_or_source_position` slot thus always contains the source position (aka the `promise index` in this case). We also added a `StackFrameInfo::ComputeLocation()` method to remove the last remaining place where we'd peek into the StackFrameInfo from outside stack-frame-info.{cc,h}.

Port 15f3392a Original Commit Message: This CL adds support for instrumentation breakpoints in wasm. The request for "break on entry" is set on the script, and we need to keep it stored there because there might not be any instances of that wasm module yet. Once instances get created, the flag value is transferred to all instances. The flag stored there is then checked in the function prologue in Liftoff debugging code. This ensures that we will stop at the first valid break position in any function within that module. Hitting that instrumentation breakpoint will then clear the flag from the script and from all other live instances (in the same isolate). A first basic test is contained in this CL. More tests will be added later.

Add a new StackFrame class for unoptimized frames (which are either interpreted or baseline). BaselineFrame becomes a subclass of this rather than InterpretedFrame, and the various frame constants helpers are similarly amended.

This adds a call to re-compile top level functions in case no shared function info could be found. We ran into a bug where it was not possible to set a breakpoint on the top-level function since it was already removed by the GC.
