The last update (using tools/wasm/update-wasm-fuzzers.sh) was in November 2020, thus update again to add modules from all existing tests to the corpus used by ClusterFuzz. This increases the number of files in the corpus from 47196 to 53779.

We might run TRACE_GC with ThreadKind::kMain not only on each isolate's main thread but also on the shared isolate's thread during a shared GC. The DCHECK is too restrictive for the latter case. This is safe because the shared GC will stop all main threads before starting its work.

CDP has a "ExceptionDetails" structure that is attached to various CDP commands, e.g. "Runtime#exceptionThrown" or "Runtime#evaluate". The stack trace in the "ExceptionDetails" structure is used in various places in DevTools. The information in the "ExceptionDetails" structure is extracted from a v8::Message object. Message objects are normally created at the exception throw site and may augment the error with manually inspecting the stack (both to capture a fresh stack trace in some cases, as well as to calculate location info). The problem is that in some cases we want to get an "ExceptionDetails" structure after the fact, e.g. when logging a JS "Error" object in a catch block. This means we can't reuse Isolate::CreateMessage as the JS stack at call time is unrelated to the time when an Error object was thrown. To re-use some of the code, this CL introduces a new "CreateMessageFromException" method that is only available from the debugging interface (not public V8 API!). The new method works similar to Isolate::CreateMessage, but: 1) Does not look at the current JS stack, neither for a fresh stack trace nor for location information. 2) Only uses the "detailed" stack trace for location info. This is because the "simple" stack trace could have already been serialized by accessing Error#stack.

This is a reland of 86038ecf Compared to the previous CL this one is adding a TSAN suppression for GlobalSafepoint::EnterSafepointScope. local_heaps_mutex_ of client isolates may be locked in any order. This would be detected by TSAN as a potential race. Add some additional DCHECKs to compensate for that missing test coverage. As a cleanup this CL also removes the unused methods ContainsLocalHeap() and ContainsAnyLocalHeap() from LocalHeap. Original change's description: > [heap] Optimize time to reach global safepoint > > Initial support for global safepoints kept it simple by entering a > safepoint for each of them one after another. This means > time-to-global-safepoint is the sum of all time-to-safepoint operations. > We can improve this slightly by splitting up the safepoint iteration > into two operations: > > 1) Initiate safepoint lock (locks local_heaps_mutex_, arms the barrier > and sets SafepointRequested flag for all client threads) > 2) Block until all runnning client threads reach a safepoint > > We now perform operation 1) for all clients first and only then start > with operation 2). > > Bug: v8:11708 > Change-Id: Iaafd3c6d70bcf7026f722633e9250b04148b3da6 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3310910 > Reviewed-by: Michael Lippautz <mlippautz@chromium.org> > Commit-Queue: Dominik Inführ <dinfuehr@chromium.org> > Cr-Commit-Position: refs/heads/main@{#78308} Bug: v8:11708, v8:12492 Change-Id: I7087ba23c08f2d4edb9b632eef3c218fc76342e7 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3328786Reviewed-by:

V8 crashed with a FATAL when memory allocation during instantiation failed. With this CL, a RangeError is thrown instead. This is not the only possible OOM that can happen during the startup of a WebAssembly app, but since the allocation of WebAssembly memory is among the biggest allocations, this change may already prevent several crashes.

Windows requires additional writable page to be allocated in front of the code range, but at the same time the code range must not cross 4 GB boundary in order to make Code pointer compression work for Code pointers. All these constraints make the logic of hint calculation too dependent on what VirtualMemoryCage::InitReservation() would do with the provided hint. This CL simplifies the hint calculation and fully relies on VirtualMemoryCage::InitReservation() to do the right thing. On Linux the implementation of OS::GetFreeMemoryRangesWithin() doesn't work when Chromium sandbox is enabled, so we use the beginning of the preferred short builtin calls region as a hint. It should be at least as good as the fallback hint but with higher chances to point to free address space location.
