Add an implementation of compare ops which, like binary ops, speculatively reads integers (but still returns a tagged true/false value).

We weren't always clearing latest_checkpoint_state on merge points, so bottleneck it in a better location. Bug: v8:7700 Change-Id: Iaac5922d769d97d49b85613d5390196a14ad8059 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3657437Reviewed-by:

Leszek Swirski authored
Deopt InputLocation next_use fields are not initialised, so if a deopt is the last use of a node we won't release it. Fix this by initialising the input location array. Also add a DCHECK to verify that register assignments match what registers a node thinks it's in.

TSAN intercepts atomic accesses and uses locking. Since YIELD_PROCESSOR is used in spinlock loops in conjunction with atomic accesses, such spinlock loops can exhibit starvation in TSAN. To work around the problem, have YIELD_PROCESSOR sleep the process for 1ms.

Add Int32/Float64 nodes for: * Subtract * Multiply * Divide and additionally Int32 nodes for * BitwiseOr/And/Xor * ShiftLeft/Right/RightLogical The latter ones don't have Float64 equivalents since they're implicitly Int32 operations. In the future we'll add support for Number feedback by adding Float64-to-Int32 conversions and using the Int32 nodes. The divide node does an Int32 division and deopts if there's a remainder to the division -- we may want to make it output a Float64 instead if we think that's more likely in real-world code. There's also no peephole optimisations for constant operations, which would generate much better code, especially for shifts.

When enabled, this API exposes a new global 'Sandbox' object which contains a number of functions and objects that in effect emulate typical memory corruption primitives constructed by exploits. In particular, the 'MemoryView' constructor can construct ArrayBuffers instances that can corrupt arbitrary memory inside the sandbox. Further, the getAddressOf(obj) and getSizeInBytesOf(obj) functions can be used respectively to obtain the address (relative to the base of the sandbox) and size of any HeapObject that can be accessed from JavaScript. This API is useful for testing the sandbox, for example to facilitate developing PoC sandbox escapes or writing regression tests. In the future, it may also be used by custom V8 sandbox fuzzers.

Adding the shared heap write barrier caused regressions on some benchmarks. Presumably this is because the compiler can't merge the fast paths of the generational and shared heap write barrier. This CL therefore introduces a CombinedHeapBarrier that manually unifies the fast path for the marking, generational and shared heap write barrier. This should make the barrier easier to optimize for the compiler. In particular it should help to ensure that page flags don't need to be loaded multiple times in a single full write barrier.

Bug: v8:12868 A slight modification to the existing DFA-based UTF-8 allocator to allow decoding surrogates, for use in decoding WTF-8. We'll need to additionally constrain the decoder to disallow surrogate pairs.

With crrev.com/c/3641564, Chromium now uses PartitionAlloc for ArrayBuffer allocations even if one of the sanizier tools (e.g. ASan) is enabled. As such, sanitizer builds are now compatible with the sandbox.
