In the preparser we don't need to worry about adding duplicate error objects to the list, so we can simply unconditionally set the error flag. Restructure the accumulator so we can also guarantee that we're checking the same flag as we're setting.

The {MaskOut} operation is faster than using {operator~}, since {operator~} needs to ensure to return a valid register list, so it contains an additional AND operation with the mask of all registers. Hence use {MaskOut} more consistently, and remove the now unused {operator~} on {LiftoffRegList}.

The implicit parameter syntax adds a second parameter list before the explicit parameter list when declaring macros, builtins and runtime functions: extern macro MyMacro(implicit a: Smi)(b: Oddball); when calling the macro, only the formal parameters can be provided at the call site. The implicit parameters are implicitly looked-up by name in the scope of the call and prepended to the explicit parameter list. The values that are found by name for each implicit parameter must be castable the corresponding implicit parameter type: MyMacro(Null); // Error, a is not defined ... const a: Smi = 0; MyMacro(Null); // OK ... const a: Object = 0; MyMacro(Null); // Error, a has wrong type For external macros, builtins and runtime functions, the formal parameter list expected on the C++ side is the concatenation of the implicit and explicit parameter lists. As a drive-by: fix the formatting of typeswitch statements in the the presence of deferred-marked blocks and funky white space.

Benedikt Meurer authored
This JSAsyncFunctionObject represents the implicit generator object inside of async functions, and also holds the outer promise for the async functions. This in turn allows us to get rid of the .promise in the Parser / BytecodeGenerator completely, and will make it possible to build zero-cost async stack traces independent of the concrete synchronous part of the stack frame (which currently breaks in Node.js). In the bytecode all the async function operations now take this new JSAsyncFunctionObject instead of passing both the .generator_object and the .promise, which further simplifies and shrinks the bytecode. It also reduces the size of async function frames, potentially making the suspend/resume cheaper. This also changes `await` to use intrinsics instead of calling to special JSFunctions on the native context, and thus reduces the size of the native contexts. Drive-by-fix: Introduce a dedicated JSCreateAsyncFunctionObject operator to TurboFan.

Port a2b34806 Original Commit Message: This CL refactors the implementation of WASM->JS import wrappers in order to make the wrapper code shareable. Instead of specializing to the import index, we use a tuple as the object ref in the both the import and indirect tables. The tuple allows the wrapper code to load both the calling instance and the target callable, rather than relying on code specialization. This requires some tricky codegen machinery, because WASM call descriptors expect an instance argument in a given register, yet the wrappers receive a tuple, the code generator must generate a prologue that loads the instance (and the callable), since it is not possible to express this at the graph level.

Jakob Gruber authored
Block coverage is based on a system of ranges that can either have both a start and end position, or only a start position (so-called singleton ranges). When formatting coverage information, singletons are expanded until the end of the immediate full parent range. E.g. in: {0, 10} // Full range. {5, -1} // Singleton range. the singleton range is expanded to {5, 10}. Singletons are produced mostly for continuation counters that track whether we execute past a specific language construct. Unfortunately, continuation counters can turn up in spots that confuse our post-processing. For example: if (true) { ... block1 ... } else { ... block2 ... } If block1 produces a continuation counter, it could end up with the same start position as the else-branch counter. Since we merge identical blocks, the else-branch could incorrectly end up with an execution count of one. We need to avoid merging such cases. A full range should always take precedence over a singleton range; a singleton range should never expand to completely fill a full range. An additional post-processing pass ensures this.

The MapIterator protector protects the original iteration behaviors of Map.prototype.keys(), Map.prototype.values(), and Set.prototype.entries(). It does not protect the original iteration behavior of Map.prototype[Symbol.iterator](). The protector is invalidated when: * The 'next' property is set on an object where the property holder is the %MapIteratorPrototype% (e.g. because the object is that very prototype). * The 'Symbol.iterator' property is set on an object where the property holder is the %IteratorPrototype%. Note that this also invalidates the SetIterator protector (see below). The SetIterator protector protects the original iteration behavior of Set.prototype.keys(), Set.prototype.values(), Set.prototype.entries(), and Set.prototype[Symbol.iterator](). The protector is invalidated when: * The 'next' property is set on an object where the property holder is the %SetIteratorPrototype% (e.g. because the object is that very prototype). * The 'Symbol.iterator' property is set on an object where the property holder is the %SetPrototype% OR %IteratorPrototype%. This means that setting Symbol.iterator on a MapIterator object can also invalidate the SetIterator protector, and vice versa, setting Symbol.iterator on a SetIterator object can also invalidate the MapIterator. This is an over- approximation for the sake of simplicity.
