This CL changes the panel layout by implementing a grid format. The new layout displays Map and IC panel side by side and making it easier to control the position of panels.

The (now unique)PersistentHandles container follows this path: 1) PersistentHandles created via PersistentHandlesScope inside of CompilationHandleScope 2) Owned by OptimizedCompilationInfo 3) Owned by JSHeapBroker 4) Owned by the broker's LocalHeap 5) Back to the broker for a brief moment (after tearing down the LocalHeap as part of exiting LocalHeapScope) 6) Back to OptimizedCompilationInfo when exiting the LocalHeapScope. There is a special case in GenerateCodeForTesting where the JSHeapBroker will not be retired in that same method. In this case, we need to re-attach the PersistentHandles container to the JSHeapBroker. The identity map of the persistent & canonical handles also gets passed around like the persistent handles. The only difference is that is created in the CanonicalHandleScope (i.e step 1) is different).

Design doc: https://docs.google.com/document/d/1n9ADWnDI-sw0OvdSmrthf61prmDqbDmQq-NSrQw2MVI/edit?usp=sharing Most of this change follows directly what is discussed in the design document. A few other things are also changed: - PopulateReferenceMapsPhase is moved after ResolveControlFlowPhase so that it can make use of the decision regarding whether a value is spilled at its definition or later. - SpillSlotLocator is removed. It was already somewhat confusing, because the responsibility for marking blocks as needing frames was split: in some cases they were marked by SpillSlotLocator, and in other cases they were marked by CommitSpillsInDeferredBlocks. With this change, that split responsibility would become yet more confusing if we kept SpillSlotLocator for the values that are spilled at their definition, so I propose a simpler rule that whatever code adds the spill move also marks the block. - A few class definitions (LiveRangeBound, FindResult, LiveRangeBoundArray, and LiveRangeFinder) are moved without modification from register-allocator.cc to register-allocator.h so that we can refer to them from another cc file.

We shouldn't spill weak pointers onto the stack when calling functions that can trigger GC. DynamicMapChecks operator was using feedback loaded from the feedback vector across the TryMigrateInstance function call. The feedback can be a weak pointer to receiver map for monomorphic cases and TryMigrateInstance can trigger a GC. This cl fixes it by holding a holding a strong reference to the feedback.

Now that background threads participate in sweeping, this method races because multiple threads now want to update that counter. We could either make this counter atomic or remove it entirely. This CL removes this counter since it isn't strictly necessary, it is only used when sweeper finds more garbage than markers. This happens e.g. with right-trimming but should be rare and is eventually fixed in the next GC.

This CL checks the version of the log file by checking the format of Map Objects processed by the IC processor. The version check requirement came from the modified IC event logging pipeline of the V8.

We only want to serialize TurboFan code, because Liftoff code could contain breakpoints, and we start thinking about embedding other non-relocatable constants. Thus, wait until top-tier compilation finished before triggering serialization. A follow-up CL will make serialization fail if any Liftoff code is encountered.

This removes the {InterpretWasmModuleForTesting} function in favor of {InterpretWasmModule}, and uses that in {InterpretAndExecuteModule}. The latter again is reused in {WasmExecutionFuzzer::FuzzWasmModule}, such that all fuzzers execute the same checks now.

This is the first step in refactoring Worklist to allow arbitrary number of local worklists with private segments: - Introduce MarkingWorklistImpl<> which will eventually replace (and will be renamed to) Worklist. - MarkingWorklistImpl<> owns the global pool of segments but does not keep track of private segments. - MarkingWorklistImpl<>::Local owns private segments and can be constructed dynamically on background threads. - Rename the existing MarkingWorklistsHolder to MarkingWorklists. - Rename the existing MarkingWorklists to MarkingWorklists::Local. - Rename the existing marking_workists_holder to marking_worklists. - Rename the existing marking_worklists to local_marking_worklists.

This change adds support for skipping locations that are in a skipList on step over. This feature is useful for when we are debugging C++ applications that have DWARF information we only want to stop on every breakable location in C++, not non every breakable location on wasm level.

This CL adds more systematic predicates to JSFunction to reason about available code kinds. Introduced terminology: - Attached code kinds are accessible directly from the JSFunction itself. - Available code kinds are either attached or accessible indirectly. - The Active code kind is the one that would be executed on the next function execution.

The "wasm fuzzer" and "wasm async fuzzer" use the {InterpretAndExecuteModule} function, which did not check for possible nondeterminism in the interpreter yet. This can lead to wrong reports of mismatches, or in endless loops being executed in compiled code which was not executed in the interpreter. This CL adds the check for nondeterminism in that function, and adds a TODO to merge the two very similar methods.

The interpreter is used for testing (including fuzzing) only, and in these cases it's often important to see the exact value of a float. Both decimal and scientific notation does not show the full value though, and decimal representation can also be really long for large values, making it hard to compare values. This CL switches this debug output to hexadecimal float values, which always shows the float value in full precision and is also much shorter than decimal notation in many cases.
