TSan reports errors if one thread changes the ref count using relaxed semantics, then another thread frees the code object. Acquire-release semantics fix this, as they impose an ordering between the memory accesses of different threads.

Between determining the set of wasm code objects to free, and actually freeing them, we should not give up the mutex of the wasm engine. Otherwise, a NativeModule can die in-between, and we would access a stale pointer. This fixes some flakes seen on the TSan bots with --stress-wasm-code-gc.

This CL add decoding and code generation for the table.grow instruction. For code generation we just generate a runtime call. The implementation is quite straight-forward. However, I did several small cleanups along the way. I hope it's still acceptable. I could also split out some cleanups into separate CLs.

Various small changes are required to enable this. HeapObject::GetReadOnlyRoots no longer uses the Space's heap when possible (see comment in ReadOnlyHeap::GetReadOnlyRoots definition). This requires that ReadOnlyRoots be construct-able using a raw pointer to the read-only space's roots array. Global read-only heap state is now cleared by tests where appropriate and extra DCHECKs in ReadOnlyHeap::SetUp should make catching future issues easier. String padding is now always cleared just before read-only space is sealed when not deserializing.

Keep the existing method for compatibility, by converting to json from CBOR using the inspector_protocol_encoding library, via a v8 specific interface library that directs routines for converting between strings and doubles to v8's implementations. This change also brings in the encoding.h / encoding.cc files from the upstream inspector_protocol project. The only modification here are the header guards, and the namespace. I will fix roll.py to make it so that we pick up future changes. third_party/inspector_protocol/BUILD.gn is specific to v8, by necessity. third_party/inspector_protocol/.clang-format is a copy of the upstream file. If we don't put this, we'll find ourselves auto-formatting the roll, which is annoying.

On Windows, expanding the stack by more than 4 KB at a time can cause access violations. This change fixes a few known cases (and includes unit tests for those), and attempts to make stack expansion more consistent overall by using the AllocateStackSpace helper method everywhere we can, even when the offset is a small constant. On arm64, there was already a consistent method for stack pointer manipulation using the Claim and Drop methods, so Claim is updated to touch every page.

Code relocation info is now always allocated in old-space. Before relocation info allocated for placeholders and builtins (which get replaced with trampolines in nosnap builds) would become unreachable. Since read-only space is not GCed and ReadOnlyHeapIterator doesn't check for reachability, ValidateSnapshot would fail finding unreachable objects returned by ReadOnlyHeapIterator. Because trampoline relocation info gets replaced with canonical one, this only affects no-embdded-builtins nosnap builds, which don't get much benefit from read-only relocation info anyway. A new check has been added to the read-only deserializer to verify that every read-only object is reachable at mksnapshot-time. The CombinedHeapIterator iteration order was changed to iterate over read-only space first, because that's how HeapIterator worked. This is a reland of 3d1d8eae Original change's description: > [heap] Skip ro-space from heap iterators, add CombinedHeapIterator. > > Read-only space sharing requires an iterator independent of heap.

The performance actually matters to JSON parsing and this improves it by a % or 2.

Port 381a7f9e Original Commit Message: On Arm/64 the last return address is stored in a link register instead of being pushed to the top-of-stack like on x64/ia32. Extend the support in the tick sampler to check for samples in a frameless bytecode handler with support for checking the link register if it exists instead of top-of-stack. In addition, make the x64/ia32 check more robust by ensuring we only apply the change if the pc is a bytecode handler and the top frame isn't a bytecode handler (stub) frame.

This reverts commit ad44c258. Reason for revert: Missed some users: crbug.com/v8/9105 Original change's description: > [typedarray] Make JSTypedArray::length authoritative. > > This is the first step towards full huge typed array support in V8. > Before this change, the JSTypedArray::length and the elements backing > store length (FixedTypedArrayBase::length) were used more or less > interchangeably to determine the number of elements in a JSTypedArray. > > With this change we disentangle these two lengths, and instead make > JSTypedArray::length authoritative. For on-heap typed arrays, the > FixedTypedArrayBase::length will remain the number of elements in the > backing store, but for the off-heap typed arrays, this length will be > set to 0 (matching the fact that the FixedTypedArrayBase instance does > not contain any elements itself). > > This also unifies the JSTypedArray::set_/length() and length_value() > methods to only have JSTypedArray::set_/length() which returns/takes > size_t values. Currently this still requires the values to be in Smi > range, but later we will extend this to allow arbitrary size_t values > (in the safe integer range). > > Bug: v8:4153, v8:7881 > Change-Id: Iff9089130bb31fa9e08e0cf913e7ab52c3dbf107 > Cq-Include-Trybots: luci.chromium.try:linux-blink-rel > Doc: http://doc/1Z-wM2qwvAuxH46e9ivtkYvKzzwYZg8ymm0x0wJaomow > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1543729 > Commit-Queue: Benedikt Meurer <bmeurer@chromium.org> > Reviewed-by: Peter Marshall <petermarshall@chromium.org> > Reviewed-by: Jaroslav Sevcik <jarin@chromium.org> > Reviewed-by: Ben Titzer <titzer@chromium.org> > Reviewed-by: Hannes Payer <hpayer@chromium.org> > Cr-Commit-Position: refs/heads/master@{#60648} TBR=jarin@chromium.org,titzer@chromium.org,hpayer@chromium.org,petermarshall@chromium.org,bmeurer@chromium.org # Not skipping CQ checks because original CL landed > 1 day ago.
