New issue 3823 by [email protected]: Embed weak JSObject in optimized code
using WeakCell
https://code.google.com/p/v8/issues/detail?id=3823
Instead of using global object-to-dependent-code table to implement weak
objects in optimized code, embed weak objects using weak cells.
This requires changing changing places in hydrogen that create HConstant
from JSObject:
HOptimizedGraphBuilder::BuildCallConstantFunction
HOptimizedGraphBuilder::BuildEmitInObjectProperties
HOptimizedGraphBuilder::BuildLoadNamedField
HOptimizedGraphBuilder::BuildMonomorphicAccess
HOptimizedGraphBuilder::BuildStoreNamedField
HOptimizedGraphBuilder::HandleGlobalVariableAssignment
HOptimizedGraphBuilder::HandlePolymorphicCallNamed
HOptimizedGraphBuilder::ImplicitReceiverFor
HOptimizedGraphBuilder::TryInlineApiCall
HOptimizedGraphBuilder::VisitVariableProxy
