This step clearly splits evaluating to a reference and - evaluating to a value, and moves all of the reference-specific - operations from Value to Reference. A special ConstReference class - helps out for the one case where you need special reference - operations if the result is a reference, and not otherwise. - - Also, Reference now inherits privately from Value, and there is a - new ReferenceList class that inherits privately from List, so the - uses of Reference and Value are now completely orthogonal. This - means that as the next step, their implementations can be - completely disentangled. - - This step has no actual performance impact. - - * kjs/collector.cpp: - (Collector::collect): - * kjs/nodes.cpp: - (Node::evaluateReference): - (ResolveNode::evaluate): - (ResolveNode::evaluateReference): - (ElementNode::evaluate): - (PropertyValueNode::evaluate): - (AccessorNode1::evaluate): - (AccessorNode1::evaluateReference): - (AccessorNode2::evaluate): - (AccessorNode2::evaluateReference): - (ArgumentListNode::evaluateList): - (NewExprNode::evaluate): - (FunctionCallNode::evaluate): - (PostfixNode::evaluate): - (DeleteNode::evaluate): - (VoidNode::evaluate): - (TypeOfNode::evaluate): - (PrefixNode::evaluate): - (UnaryPlusNode::evaluate): - (NegateNode::evaluate): - (BitwiseNotNode::evaluate): - (LogicalNotNode::evaluate): - (MultNode::evaluate): - (AddNode::evaluate): - (ShiftNode::evaluate): - (RelationalNode::evaluate): - (EqualNode::evaluate): - (BitOperNode::evaluate): - (BinaryLogicalNode::evaluate): - (ConditionalNode::evaluate): - (AssignNode::evaluate): - (CommaNode::evaluate): - (VarDeclNode::evaluate): - (ExprStatementNode::execute): - (IfNode::execute): - (DoWhileNode::execute): - (WhileNode::execute): - (ForNode::execute): - (ForInNode::execute): - (ReturnNode::execute): - (WithNode::execute): - (CaseClauseNode::evaluate): - (SwitchNode::execute): - (ThrowNode::execute): - * kjs/nodes.h: - * kjs/types.cpp: - (ConstReference::ConstReference): - * kjs/types.h: - * kjs/value.h: - -2002-08-15 Darin Adler <darin@apple.com> - - Tweaks and small bug fixes to Maciej's excellent new fixnum optimization. - Also updated or removed comments that call it "fixnum" instead of "simple number". - - * kjs/simple_number.h: Change constant names so they don't SHOUT the way macro - names do.
