* V4: Clean up the runtime functions declarationsErik Verbruggen2019-02-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | The declarations and usage of runtime functions have seen a number of changes: - we don't use the array of method pointers anymore because we don't use cross-platform AOT JITting - the check if a method can throw a JS exception was invalid, and was not used anymore - value-pointer vs. const-value-ref was inconsistent This patch cleans that up. By fixing the exception checking, we can now use it in the baseline JIT to automatically insert those checks. To make that work correctly, all runtime methods are in a struct, which gets annotated to indicate if that method throws. (The old way of checking which type of engine was used is fragile: some non-throwing methods do not take an engine parameter at all, and those got flagged as throwing). By using a struct, we can also get rid of a bunch of interesting macros. The flags in the struct (as mentioned above) can later be extended to capture more information, e.g. if a method will change the context.

* Fix dead temporal zone checking in module namespacesSimon Hausmann2018-08-291-0/+7
| | | | | | | | | | | | | | | Accessing uninitialized imports through the module namespace object should throw a reference error. Unfortunately we can't do this check on the caller side of the namespace object get, as we have no idea that we're talking to one. Therefore we must throw in the vtable methods. When checking via Reflect.has(), the properties should be reported as existing. This means providing a virtual hasProperty() in the module as well as changing Reflect::method_has to use the vtable method instead of doing a get (which would throw).

At the same time, expose them on TypedArray's prototype: - 22.2.3.15 %TypedArray%.prototype.keys - 22.2.3.29 %TypedArray%.prototype.values - 22.2.3.6 %TypedArray%.prototype.entries - 22.2.3.31 %TypedArray%.prototype[Symbol.iterator] For TypedArray, test coverage improves a tiny bit (3 passing tests), but the vast majority fail as it seems like the object structure for TypedArray is currently incomplete as far as ES6 expects. It seems that ES6 expects the object structure to be: * %TypedArray% (inherits FunctionObject) (this is the TypedArray intrinsic object, and responsible for initializing the TypedArray instances) * All the TypedArray ctors (e.g. UInt8Array) These inherit %TypedArray%, and make a super call to it to do their work * %TypedArrayPrototype% (inherits Object) (this is the initial prototype for %TypedArray%) * All the ctors have their own separate instance of this * The instances also make use it So, for instance, a lot of the tests attempt to access the prototype like: var proto = Object.getPrototypeOf(Int8Array) var keys = proto.prototype.keys As ES6 expects Int8Array.prototype to be %TypedArray% (22.2.5), this expands to: Object.getPrototypeOf(%TypedArray%) which it expects to be %TypedArrayPrototype%. But since we have no intrinsic object, and the ctors inherit FunctionObject, we instead return the wrong prototype into 'var proto'.
