JavaScriptCore:
- 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.
