If a {NativeModule} dies while a GC is running, we could leave behind references to code of that deleted module. This CL fixes that. This issue was found by running with --stress-wasm-code-gc.

The function {memory_copy_wrapper} is called directly from WebAssembly. Before calling {memory_copy_wrapper} we do not reset the tread-in-wasm flag. On asan builds on Windows this causes the problem observed in the crash report. My theory is the following: asan on Windows uses exceptions to allocate shadow memory lazily. When {memory_copy_wrapper} accesses memory, asan causes an exception to allocate shadow memory. This exception is first caught by the WebAssembly trap handler, which resets the thread-in-wasm flag but then does not handle the exception because it cannot find a proper landing pad. Asan then handles the exception and continues execution. However. the thread-in-wasm flag is not set anymore. A later check of the thread-in-wasm flag then fails. This CL disables asan for {memory_copy_wrapper} and thereby fixes the problem. As indicated above, another solution would be to reset and set the thread-in-wasm flag before and after the call to the C function, respectively. However, we do not do that for other uses of direct calls to C.

The `Script::InitLineEnds(Handle<Script>(script, isolate));` line may lead to objects being moved around on the heap, so it’s necessary to use a `Handle` to track that.

This fixes a deadlock that was detected by layout tests executing with --future (hence enabling wasm code gc). It did not fail anywhere in v8 because GC is only triggered once we have > 1MB potentially dead code. I plan to add a '--stress-wasm-code-gc' flag, which lowers this limit to zero, thereby triggering GC when finding a single potentially dead code. This mode found this issue, but also finds more, so I need to fix other issues before enabling these stress tests.

With very few exceptions, this verifies all skipped write-barriers in CSA and Torque, showing that the MemoryOptimizer together with some type information on the stored value are enough to avoid unsafe skipped write-barriers. Changes to CSA: SKIP_WRITE_BARRIER and Store*NoWriteBarrier are verified by the MemoryOptimizer by default. Type information about the stored values (TNode<Smi>) is exploited to safely skip write barriers for stored Smi values. In some cases, the code is re-structured to make it easier to consume for the MemoryOptimizer (manual branch and load elimination). Changes to the MemoryOptimizer: Improve the MemoryOptimizer to remove write barriers: - When the store happens to a CSA-generated InnerAllocate, by ignoring Bitcasts and additions. - When the stored value is the HeapConstant of an immortal immovable root. - When the stored value is a SmiConstant (recognized by BitcastToTaggedSigned). - Fast C-calls are treated as non-allocating. - Runtime calls can be white-listed as non-allocating. Remaining missing cases: - C++-style iterator loops with inner pointers. - Inner allocates that are reloaded from a field where they were just stored (for example an elements backing store). Load elimination would fix that. - Safe stored value types that cannot be expressed in CSA (e.g., Smi|Hole). We could handle that in Torque. - Double-aligned allocations, which are not lowered in the MemoryOptimizer but in CSA. Drive-by change: Avoid Smi suffix for StoreFixedArrayElement since this can be handled by overload resolution (in Torque and C++).

This is a reland of 3d846115 Reland changes mjsunit.status to skip the regression test on all bots except ASAN. Original change's description: > [typedarray] Fix crash when sorting SharedArrayBuffers > > TypedArray#sort has a fast-path when the user does not provide a > comparison function. This fast-path utilizes std::sort which operates > directly on the raw data. Per spec, std::sort requires the "less than" > operation to be anti-symmetric and transitive. > > When sorting SharedArrayBuffers (SAB) that are concurrently modified during > sorting, the "less than" operator stops being consistent as the > underlying data is constantly modified. This breaks some invariants > in std::sort resulting in infinite loops or straight out segfaults. > > This CL fixes this by copying the data before sorting SABs and > writing the sorted result back. > > Note: The added regression test is tailored for ASAN bots as a > normal build would need too many iterations to consistently crash. > > R=neis@chromium.org, petermarshall@chromium.org > > Bug: v8:9161 > Change-Id: Ic089928652f75865bfdb11e7453806faa6ecb988 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1581641 > Reviewed-by: Peter Marshall <petermarshall@chromium.org> > Reviewed-by: Georg Neis <neis@chromium.org> > Commit-Queue: Simon Zünd <szuend@chromium.org> > Cr-Commit-Position: refs/heads/master@{#61004} Bug: v8:9161 Change-Id: Idffc3fbb5f28f4966c8f1ac6770d5b5d6003a7e7 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1583726Reviewed-by:

Verify that baseline and top tier compilation are finished when expected. Test cases will use the newly exposed functions {baseline_compilation_finished} and {top_tier_compilation_finished} for this.
