By adding LoadIC support for JSModuleNamespace objects. The index of the corresponding slot in the Module's "exports" dictionary is cached in the feedback vector, so the value can be loaded directly, without having to call the C++ accessor.

Currently, injected script source adds natural object properties before internal properties. This can result in important ones such as "[[PrimitiveValue]]" being left out. This CL - makes sure internal properties are always added to preview - removes unused "[[Iterator*]]" properties from preview - boxed strings (e.g. new String("foo")) will not send unnecessary properties 0:"f", 1:"o", 2:"o" if the [[PrimitiveValue]] is sent.

This change adapts the Call bytecode handlers such that they don't require a stack frame. It does this by modifying the call bytecode handler to tail-call the Call or InterpreterPushArgsAndCall builtins. As a result, the callee function will return to the InterpreterEntryTrampoline when it returns (since this is the return address on the interpreter frame), which is adapted to dispatch to the next bytecode handler. The return bytecode handler is modified to tail-call a new InterpreterExitTramoline instead of returning to the InterpreterEntryTrampoline. Overall this significanlty reduces the amount of stack space required for interpreter frames, increasing the maximum depth of recursive calls from around 6000 to around 12,500 on x64.

Leszek Swirski authored
For deferred commands (such as in try-finally), some deferred commands save and restore the accumulator using a result register (e.g. return, throw, rethrow), while others don't (e.g. break, continue, fall-through). However, conditionally reading this result register that may not ever be written caused it to be considered live from the start of the function, as far as the liveness analysis could statically tell. Now, we write the result register for all deferred commands, including the fall-through. As a micro-optimization, we re-use the Smi command tokeen to clobber the result, rather than emitting an LdaUndefined.

The Uint32(limit) conversion can end up transitioning the regexp instance to slow mode. In this case we need to bail out to runtime while ensuring that ToUint32 is not observably called a second time. We do this by passing the already-converted value to runtime. This particular path was broken and we ended up passing the original maybe_limit value to runtime instead.

Do not allow recursive inlining when function calls itself. i.e.f() -> f() This is because we only get some static information for the first level of inlining and it may not be very beneficial to just duplicate the entire function. However, we still allow indirect recursion f() -> g() -> f() -> g1(). This helps in cases where f() is a small dispatch function. For example, in rayTrace class.create -> obj.initialize -> class.create -> obj1.initialize.

For wide bytecodes, save the bytecode offset as the offset of the prefix bytecode, rather than the bytecode itself. This means that any code that reads the bytecode can explicitly know the width of the bytecode at the offset without having to iterate through the complete bytecode array. Also simplifies some code in the bytecode analysis that had to work around the previous approach.

Jakob Gruber authored
As a first step towards lazy builtin deserialization, this CL moves builtins to their own dedicated area in the snapshot blob, physically located after startup data and before context-specific data. The startup- and partial serializers now serialize all seen builtins as references, i.e. they only encode the relevant builtin id (taking care to preserve special behavior around the interpreter trampoline and CompileLazy). Builtins are later fully serialized by the BuiltinSerializer. The separate blobs are finally glued together by CreateSnapshotBlob. Deserialization takes the same steps: when we see builtin reference bytecodes before builtins have been deserialized, we push to a list of deferred builtin references. After builtin deserialization, this list is iterated and all builtin references are fixed up.
