Since the accessors are only called from other methods in the same class, we can just access the field directly. This makes stepping through easier and makes the code simpler by avoiding an unneeded abstraction.

The register state is accessed a lot in the mid-tier register allocator. Instead of going through an accessor with a DCHECK, just access directly. This makes stepping for debugging a lot easier, and will result in an easy-to-debug nullptr access if the register state is not initialized.

Spilling was already fixed if a fixed SIMD register overlaps with an allocated FP register, but the other way around was missing: If an odd FP register (in this case d1) is used as a fixed output register, but this register is in use as the upper half of a SIMD register (in this case q0), we did not detect this and would just use overwrite the SIMD half. This CL also fixes this case.

https://crrev.com/c/3297708 changed the serialization format for typed arrays without bumping the format version. As a consequence, builds that include that CL fail to deserialize typed arrays serialized by previous V8 versions. This CL reverts the serialization format change, and does minimal test changes to reflect the revert. https://crbug.com/v8/12532 tracks serializing typed array flags in a backwards-compatible manner.

In the C++20 a following paper was implemented [1]. This paper makes code below illformed. The high level idea is that as soon as class gets non default constructor - all default initializations are not added implicitly. class A { public: A(const A&) = delete; }; int main() { A a{}; return 0; } So if V8 embedder is building its code with C++20 it can not initialize v8::CppHeapCreateParams struct and as a result can not create a CppHeap. One of the possible mitigations (3.3) from the paper is to add non copyable field into class. Luckily there is std::vector<std::unique_ptr>> in this class already.

Clang 12 doesn't support -Wno-bitwise-instead-of-logical, so silence it with -Wno-unknown-warning-option.

We add fast paths for the most common types of expressions in {EvaluateInitExpression} to improve instantiation time. We fall back to full expression decoding for less common operators, or for expressions with operands.

We implement loop peeling for wasm, currently available behind a flag. Loops are peeled regardless of size.

Introduce a build-time flag to disable all CET shadow-stack manipulation. This will allow us to develop the feature without breaking production code, and enable it all at once once the feature is ready.

When computing the code size estimate for {PrepareAndStartCompile}, we did not consider Liftoff code in the async path. Other invocations checked {FLAG_liftoff} to decide whether Liftoff code will be generated. This CL fixes the async path to do the same, and renames {uses_liftoff} to {include_liftoff} to match the name of the parameter in {EstimateNativeModuleCodeSize}.

The jump table sizes were added to the estimated code size, and then again added for computing the reservation size for the code. This CL moves the jump table size from {EstimateNativeModuleCodeSize} to {EstimateNativeModuleMetaDataSize} so it is still considered for the total memory associated with the {NativeModule}, but only added once for the code space reservation.

The V8InspectorSessionImpl constructor accepts a state, as either text or CBOR encoded, and generally ignores all invalid inputs, except for the case where it's a valid value, but not a dictionary value, in which case it'll leak the value and crash upon casting to a `DictionaryValue`. This is purely an issue with the test driver, so no security impact on Chromium in the wild.

This method performs exactly the same operation as the official `v8::Exception::GetStackTrace()`, which is already used in other places, so there's no point to have a duplicate of that in the debug interface.
