We move js-to-wasm wrappers to a WeakFixedArray in the isolate, indexed by their canonical type index. This ensures that they are reused across instances, and get GC'd when no longer needed. We also remove eager compilation of wrappers. This CL fixes some issues that were caused by out-of-bounds accesses to wrapper arrays attached to module objects.

Align slow path allocation with V8 in that: 1. Try to refill from the free list. 2. Perform limited sweeping of a space if necessary and retry the free list. 3. Try to expand the space. 4. Perform full sweeping of a space if necessary and retry the free list. 5. Finish sweeping fully as we would anyways do a GC at this point. 6. Retry the free list again 7. Try expanding again as finishing sweeping may have freed up pages. Specifically, this adresses a performance problem where we would fully sweep the whole heap, possibly causing 100ms of jank on allocation. In such cases the new approach maintains performance and stays fast at the expense of using more memory. Allocations usually find memory in 1.-3. Steps 4.-7. are slow paths that are definitely expensive but prevent failing with OOM.

Isolate::shared_isolate() was used in many locations to check for the shared heap feature. Now that we also have shared_space_isolate() checking shared_isolate() isn't sufficient anymore. This CL replaces many invocations of this method with either has_shared_heap() or shared_heap_isolate(). These methods work for both shared_isolate() and shared_space_isolate(). As soon as we remove the shared isolate we can remove them again.

The number of feedback vector slots is currently stored in the {WasmFunction}, returned in the {WasmCompilationResult}, and implicitly stored as the size of the {call_targets} vector in {FunctionTypeFeedback}. This CL uses the latter as the source of truth, encapsulated in a new {NumFeedbackSlots} function. This can be updated when adding new kinds of feedback that need additional slots. For now, the implementation of {NumFeedbackSlots} requires taking a mutex, which we can hopefully avoid when productionizing speculative inlining. We also take the mutex on every Liftoff compilation, which adds synchronization between concurrent compilation which we previously tried very hard to avoid (because it introduced significant overhead for eager compilation). As a nice side-effect, this CL reduces the per-function overhead by 8 bytes, independent of enabled features.

We can't freely concatenate strings in the background because they could be mutated by the main thread (eg, flattened, internalized, externalized...). So, when there is a JSAdd between 2 constant strings, we first checked if they are "safe" (= internalized, I think), and if so, we concatenate them at compile time. If they are "unsafe", then we don't. It turns out that this wasn't an issue with delayed constant strings, since the content of the strings were never accessed: the actual concatenations were done on the main thread, where it's safe to do. This CL fixes that for most cases: - if the strings really cannot be read from the background, but the length of their concatenation is more than ConsString::kMinLength, then we create a ConsString. - I added a set to record which strings we created in the turbofan: those strings can safely be accessed from turbofan regardless of their type. The only case where delayed constant strings could be a bit better is when there is a concatenation of 2 small non-internalized string, because right now, we wouldn't fold it. Still, it should happen very rarely, if ever.

A recent refactoring changed the behavior of dropping/keeping results after test execution. The numfuzz loop has previously treated all results as analysis results, as it expected that others are dropped. After keeping all results, the second round invalidated the analysis results and the test loop stopped early. We now add an additional safeguard that ensures the received result is indeed associated with an analysis run and do not depend anymore on result presence/absence. This also adds all analysis-based instances to the test cases.

Now several of the production fuzzers are used to run fake test cases. The overall timeout signal, used to stop numfuzz, is mocked with a counter.

This reverts commit 4444874c. Reason for revert: CHECK failure under UBSan https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux64%20UBSan%20-%20builder/5103/overview Original change's description: > [v8] Use |AllocateAtLeast| for resizing v8 zones. > > This is part of an ongoing effort to reduce fragmentation in Chrome. Partition alloc shows v8 zones are a large user of memory in Renderer processes, and that there is fragmentation from these allocations. This CL will reduce this fragmentation by allowing v8 to use all allocated memory for its zones. > > Bug: v8:13193, chromium:1238858 > Change-Id: Ibeac8bdba9d0e7ff66b14a3dde10e7c87d3cf953 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3889361 > Reviewed-by: Adam Klein <adamk@chromium.org> > Commit-Queue: Thiabaud Engelbrecht <thiabaud@google.com> > Reviewed-by: Michael Lippautz <mlippautz@chromium.org> > Cr-Commit-Position: refs/heads/main@{#83235} Bug: v8:13193, chromium:1238858 Change-Id: I03c8c1ad7bb1cd20770323bffe1c42a4be47c454 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3900814 Commit-Queue: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Auto-Submit: Adam Klein <adamk@chromium.org> Cr-Commit-Position: refs/heads/main@{#83237}
