Lazy deserialization requires a fully set-up isolate (in particular, we need Isolate::snapshot_blob). This CL disables lazy deserialization in affected tests. This should be fixed at some point by setting up the isolate as needed.

When setting up an isolate for serialization, we need to disable lazy deserialization to avoid replacing lazy builtins with DeserializeLazy. Bug: v8:6624 Change-Id: I3e10e262f6dd856f92fd83e5e475127e8ca3f3bf Reviewed-on: https://chromium-review.googlesource.com/655161Reviewed-by:

The optimizer produces direct calls to these builtins. Lazy deserialization depends on the existance of a shared function info, so these need to be blacklisted for now.

kNextChunk handling in deserializer.cc relies on the reservation mechanism, which is not used by builtin deserialization. To avoid complications, we work around this for now by skipping over these bytecodes. This will soon become unnecessary once allocations & reservations have been refactored.

With lazy deserialization, the target code object may have been replaced by DeserializeLazy. In that case, we can get the target builtin id from the shared function info, and we need to skip RelocInfo iteration (it doesn't exist yet).

What happened: - When rewriting in DoParseFunction, the relevant function scope is no longer in the scope stack. - The correct scope is given to the PatternRewriter. - PatternRewriter called to Parser::BuildIteratorCloseForCompletion. - BuildIteratorCloseForCompletion would just call NewTemporary (which creates a new temporary in Parser's current scope) instead of using the scope passed to it and calling NewTemporary on it. - Normally this went unnoticed, since it doesn't matter that much where the temporary is. - But in the lazy arrow func case, the Parser's scope at that point was the already-resolved outer scope, and a DCHECK detected this problem. Kudos & thanks to verwaest@ for a debugging session :) BUG=chromium:761831 Change-Id: I1e8474ce927be0330f4ba4efc0fc08fdcc328809 Reviewed-on: https://chromium-review.googlesource.com/650297 Commit-Queue: Marja Hölttä <marja@chromium.org> Reviewed-by:

There are two main reasons to move DeserializeLazy to ASM: 1. We avoid complications around the distinction between Call/Construct cases by making sure relevant registers (e.g. new_target) remain unclobbered. 2. We can avoid the tail-call through CodeFactory::Call/Construct by jumping directly to the deserialized code object.

The wasm-async fuzzer uses the bytes provided by the fuzzer engine directly as wasm module bytes, compiles them with async compilation, and then tries to execute the "main" function of the module. This "main" can have an infinite loop which causes a timeout in the fuzzer. With this CL the "main" function is first executed with the interpreter. If the execution in the interpreter finishes within 16k steps, which means that there is no infinite loop, also the compiled code is executed. I added the raw fuzzer input as a test case because in this case I really want to test the fuzzer and not V8.

JS runtime calls are always created with undefined recievers, so make the bytecode behave similarly to CallUndefinedReciever such that we don't need to push an explicit undefined register for the receiver for such calls. Modifies the Async[Generator/Function]Await[Caught/Uncaught] runtime calls to pass the generator in the first argument rather than the reciever since these runtime calls were desugered in the bytecode generator and explicitly passed the generator in the receiver.

Introduce NodeProperties::NoObservableSideEffectBetween to check if there's any observable side effect between two nodes in the effect chain. Use this to guard the insertion of potentially redundant map checks in the lowering of Object.prototype.hasOwnProperty and keyed accesses within a for..in loop.

The lazy deserialization builtin id is usually set when the shared function info is created in Factory::NewSharedFunctionInfo, which looks at the given code object to grab the builtin id. However, this doesn't work when the shared function info is created after deserialization, as is the case for harmony features that can be toggled with runtime flags. At this point, lazy builtins have already been replaced by DeserializeLazy in the builtins table. To ensure that the lazy deserialization id is correct in this case, explicitly set it in bootstrapper functions.
