This method will be used for a test with multiple code spaces, to encode large function indexes. The current implementation in {wasmI32Const} just always uses 5 bytes for encoding the LEB value. This CL adds a {wasmSignedLeb} function which properly encodes the value, and adds tests for that. Drive-by: Clean up the rest of {test-wasm-module-builder.js}.

iOS still uses the recipe-side toolchain, so calling the mac_toolchain script on src-side is useless in iOS checkouts.

This patch adds: - VariableMode::kPrivateMethod - VariableMode::kPrivateSetterOnly - VariableMode::kPrivateGetterOnly - VariableMode::kPrivateGetterAndSetter And replace the previous RequiresBrandCheckFlag by inferring whether the brand check is required from these VariableModes. It is then possible to check duplicate non-complementary accessors in the parsers and throw early errors, and allow complementary accessors to be associated with the same private name variable. This patch also adds the following AssignType: - PRIVATE_METHOD - PRIVATE_GETTER_ONLY - PRIVATE_SETTER_ONLY - PRIVATE_GETTER_AND_SETTER corresponding to the new VariableModes so that it's possible to generate specialized code for different type of private accessor declarations.

On Windows, the FP stack registers are used with less precision. This causes rounding errors in the uint64 to float32 conversion. This CL replaces the implementation based on FP stack registers with an implementation based on bit operations. This implementation is 2x slower than the original implementation. An alternative would be to change the precision of the FP stack registers just for the uint64 to float32 conversion. However, in a micro-benchmark this is 5-6x slower than the original implementation. It is also not clear if changing the precision could cause side effects.

Previously, this was run as a microtask and this CL changes it to run as a separate task as mandated by the current WeakRef spec. This CL also introduces a FinalizationGroup type to the V8 API representing the JSFinalizationGroup. This has a `Cleanup` function that runs the cleanup callback associated with it. SetHostCleanupFinalizationGroupCallback is added to set the embedder defined HostCleanupFinalizationGroupCallback. ClearKeptObject is exposed on the v8::Isolate to reset the strongly held set of objects. The general workflow is the following: (a) When the GC notices that a given finalization group has dirty cells, it calls HostCleanupFinalizationGroupCallback with the given finalization group. (b) As part of HostCleanupFinalizationGroupCallback, the embedder enqueues a task that at some point later calls FinalizationGroup::Cleanup. (c) At some point in the future, FinalizationGroup::Cleanup is called, which runs the cleanup callback of the finalization group. This patch also includes d8 changes to use these new APIs. Currently, d8 cycles through the enqueued finalization groups after a synchronous turn (and it's microtask checkpoint) and runs the cleanup callbacks.

This allows to return bool values from Torque macros and branch on them without performance penalty, reconstructing good control flow. Drive-by cleanup: Delete EnsureDeferredCodeSingleEntryPoint(), since it's no longer needed. Constructing a graph and then re-inferring deferred blocks based on branch hints achieves this effect automatically.

Currently, each single CSA_ASSERT invokation creates its own lambda, which is then wrapped in a {std::function} and passed to {CodeStubAssembler::Assert}. It takes a lot of compile time for clang to generate all the code for that. This CL introduces a more light-weight alternative to {CodeStubAssembler::Assert} which just receives the node directly. This reduces compile time of {code-stub-assembler.cc} in optdebug mode from ~30 seconds to ~17 seconds locally.

Like the predecessor change https://crrev.com/c/v8/v8/+/1702125 , this change is inspired by attempting to exit earlier from generated RegExp code, when no further matches are possible because any match would be too long. The motivating example this time is the following expression, which tests whether a string of Unicode playing cards has five of the same suit in a row: /([🂡-🂮]{5})|([🂱-🂾]{5})|([🃁-🃎]{5})|([🃑-🃞]{5})/u A human reading this expression can readily see that any match requires at least 10 characters (5 surrogate pairs), but the LoopChoiceNode for each repeated option reports its minimum distance to the end of a match as zero. This is correct, because the LoopChoiceNode's behavior depends on additional state (the loop counter). However, the preceding node, a SET_REGISTER action that initializes the loop counter, could confidently state that it consumes at least 10 characters. Furthermore, when we try to emit a quick check for that action, we could follow only paths from the LoopChoiceNode that are possible based on the minimum iteration count. This change implements both of those "could"s. I expect this improvement to apply pretty broadly to expressions that use minimum repetition counts and that don't meet the criteria for unrolling. In this particular case, I get about 12% improvement on the overall UniPoker test, due to reducing the execution time of this expression by 85% and the execution time of another similar expression that checks for n-of-a-kind by 20%.

Fixes a bytecode mismatch for arrow functions with default arguments between eager and lazy compilation. In the former case, parameters with default values are marked as assigned even if the value never changes within the function because the parser does not know it's an arrow-function at the point it sees the assignment. So this changes ArrowHeadParsingScope::ValidateAndCreateScope to clear the is_assigned flag on its parameter VariableProxies before it binds them.

Instead of storing the values of the single precision floating point registers, get their values from the aliased double precision registers. This saves, on arm64, 184 bytes per deoptimisation kind function (552 in total) and 128 bytes in the RegisterValues class.

We have hundreds of classes that derive from {BitField} without adding any functionality. This CL switches all such occurrences to 'using' declarations instead. Before: class MyBitField : public BitField<int, 6, 4, MyEnum> {}; After: using MyBitField = BitField<int, 6, 4, MyEnum>; This might reduce compilation time by reducing the number of existing classes. The old pattern is forbidden now by making {BitField} final.

This makes function objects constructed via the {WebAssembly.Function} constructor callable directly from JavaScript (not just from within WebAssembly modules). Semantics are as if the function performed the transition JS-to-Wasm and then Wasm-to-JS in sequence.

The preprocessor of MSVC works differently for empty __VA_ARGS__. Another hack is needed to make this compile in both MSVC and clang.
