- change ScopeChain to be a singly linked list shares tails, gives 11% gain on iBench * kjs/context.h: (ContextImp::pushScope): Make inline, use push instead of prepend, and pass imp pointer. (ContextImp::popScope): Make inline, use pop instead of removeFirst. * kjs/function.cpp: (DeclaredFunctionImp::DeclaredFunctionImp): No need to copy. * kjs/function_object.cpp: (FunctionObjectImp::construct): Use push instead of prepend, and pass imp pointer. * kjs/internal.cpp: (ContextImp::ContextImp): Use clear, push instead of prepend, and pass imp pointers. * kjs/nodes.cpp: (ResolveNode::evaluateReference): Use isEmpty, pop, and top instead of ScopeChainIterator. * kjs/object.h: Change _scope to be a NoRefScopeChain. * kjs/object.cpp: No need to initialize _scope any more, since it's not a NoRefScopeChain. * kjs/scope_chain.h: Rewrite, different implementation and interface. * kjs/scope_chain.cpp: More of the same. WebCore: * khtml/ecma/kjs_dom.cpp: (DOMNode::pushEventHandlerScope): Change to push handlers on an existing scope chain rather than returning one. Name change too. * khtml/ecma/kjs_dom.h: More of the same. * khtml/ecma/kjs_html.cpp: (KJS::HTMLElement::pushEventHandlerScope): And here. * khtml/ecma/kjs_html.h: And here. * khtml/ecma/kjs_events.cpp: (JSEventListener::handleEvent): Use the pushEventHandlerScope function, and also don't worry about optimizing the "no change" case, because that already works pretty efficiently. git-svn-id: http://svn.webkit.org/repository/webkit/trunk@2824 268f45cc-cd09-0410-ab3c-d52691b4dbfc
