Bug 25674: syntax tree nodes should use arena allocation
Part one: Change lifetimes so we won't have to use reference
counting so much, but don't eliminate the reference counts
entirely yet.

  • bytecompiler/BytecodeGenerator.cpp: (JSC::BytecodeGenerator::BytecodeGenerator): Update for use of raw pointers instead of RefPtr. (JSC::BytecodeGenerator::emitCall): Ditto. (JSC::BytecodeGenerator::emitConstruct): Ditto.
  • parser/Grammar.y: Update node creating code to use new (JSGlobalData*) instead of the plain new. At the moment this is just a hook for future arena allocation; it's inline and JSGlobalData* is not used.
  • parser/NodeConstructors.h: Updated for name change of parserObjects to parserArena. Also added explicit initialization for raw pointers that used to be RefPtr. Also removed some uses of get() that aren't needed now that the pointers are raw pointers. Also eliminated m_parameter from FuncExprNode and FuncDeclNode. Also changed node-creating code to use new (JSGlobalData*) as above.
  • parser/Nodes.cpp: Eliminated NodeReleaser and all use of it. (JSC::ParserRefCounted::ParserRefCounted): Updated for name change of parserObjects to parserArena. (JSC::SourceElements::append): Use raw pointers. (JSC::ArrayNode::emitBytecode): Ditto. (JSC::ArrayNode::isSimpleArray): Ditto. (JSC::ArrayNode::toArgumentList): Ditto. (JSC::ObjectLiteralNode::emitBytecode): Ditto. (JSC::PropertyListNode::emitBytecode): Ditto. (JSC::BracketAccessorNode::emitBytecode): Ditto. (JSC::DotAccessorNode::emitBytecode): Ditto. (JSC::ArgumentListNode::emitBytecode): Ditto. (JSC::NewExprNode::emitBytecode): Ditto. (JSC::EvalFunctionCallNode::emitBytecode): Ditto. (JSC::FunctionCallValueNode::emitBytecode): Ditto. (JSC::FunctionCallResolveNode::emitBytecode): Ditto. (JSC::FunctionCallBracketNode::emitBytecode): Ditto. (JSC::FunctionCallDotNode::emitBytecode): Ditto. (JSC::CallFunctionCallDotNode::emitBytecode): Ditto. (JSC::ApplyFunctionCallDotNode::emitBytecode): Ditto. (JSC::PostfixBracketNode::emitBytecode): Ditto. (JSC::PostfixDotNode::emitBytecode): Ditto. (JSC::DeleteBracketNode::emitBytecode): Ditto. (JSC::DeleteDotNode::emitBytecode): Ditto. (JSC::DeleteValueNode::emitBytecode): Ditto. (JSC::VoidNode::emitBytecode): Ditto. (JSC::TypeOfValueNode::emitBytecode): Ditto. (JSC::PrefixBracketNode::emitBytecode): Ditto. (JSC::PrefixDotNode::emitBytecode): Ditto. (JSC::UnaryOpNode::emitBytecode): Ditto. (JSC::BinaryOpNode::emitStrcat): Ditto. (JSC::BinaryOpNode::emitBytecode): Ditto. (JSC::EqualNode::emitBytecode): Ditto. (JSC::StrictEqualNode::emitBytecode): Ditto. (JSC::ReverseBinaryOpNode::emitBytecode): Ditto. (JSC::ThrowableBinaryOpNode::emitBytecode): Ditto. (JSC::InstanceOfNode::emitBytecode): Ditto. (JSC::LogicalOpNode::emitBytecode): Ditto. (JSC::ConditionalNode::emitBytecode): Ditto. (JSC::ReadModifyResolveNode::emitBytecode): Ditto. (JSC::AssignResolveNode::emitBytecode): Ditto. (JSC::AssignDotNode::emitBytecode): Ditto. (JSC::ReadModifyDotNode::emitBytecode): Ditto. (JSC::AssignBracketNode::emitBytecode): Ditto. (JSC::ReadModifyBracketNode::emitBytecode): Ditto. (JSC::CommaNode::emitBytecode): Ditto. (JSC::ConstDeclNode::emitCodeSingle): Ditto. (JSC::ConstDeclNode::emitBytecode): Ditto. (JSC::ConstStatementNode::emitBytecode): Ditto. (JSC::statementListEmitCode): Ditto. (JSC::BlockNode::emitBytecode): Ditto. (JSC::ExprStatementNode::emitBytecode): Ditto. (JSC::VarStatementNode::emitBytecode): Ditto. (JSC::IfNode::emitBytecode): Ditto. (JSC::IfElseNode::emitBytecode): Ditto. (JSC::DoWhileNode::emitBytecode): Ditto. (JSC::WhileNode::emitBytecode): Ditto. (JSC::ForNode::emitBytecode): Ditto. (JSC::ForInNode::emitBytecode): Ditto. (JSC::ReturnNode::emitBytecode): Ditto. (JSC::WithNode::emitBytecode): Ditto. (JSC::CaseBlockNode::tryOptimizedSwitch): Ditto. (JSC::CaseBlockNode::emitBytecodeForBlock): Ditto. (JSC::SwitchNode::emitBytecode): Ditto. (JSC::LabelNode::emitBytecode): Ditto. (JSC::ThrowNode::emitBytecode): Ditto. (JSC::TryNode::emitBytecode): Ditto. (JSC::ScopeNodeData::ScopeNodeData): Use swap to transfer ownership of the arena, varStack and functionStack. (JSC::ScopeNode::ScopeNode): Pass in the arena when creating the ScopeNodeData. (JSC::ProgramNode::ProgramNode): Made this inline since it's used in only one place. (JSC::ProgramNode::create): Changed this to return a PassRefPtr since we plan to have the scope nodes be outside the arena, so they will need some kind of ownership transfer (maybe auto_ptr instead of PassRefPtr in the future, though). Remove the node from the newly-created arena to avoid a circular reference. Later we'll keep the node out of the arena by using a different operator new, but for now it's the ParserRefCounted constructor that puts the node into the arena, and there's no way to bypass that. (JSC::EvalNode::EvalNode): Ditto. (JSC::EvalNode::create): Ditto. (JSC::FunctionBodyNode::FunctionBodyNode): Ditto. (JSC::FunctionBodyNode::createNativeThunk): Moved the code that reseets the arena here instead of the caller. (JSC::FunctionBodyNode::create): Same change as the other create functions above. (JSC::FunctionBodyNode::emitBytecode): Use raw pointers.
  • parser/Nodes.h: Removed NodeReleaser. Changed FunctionStack to use raw pointers. Removed the releaseNodes function. Added an override of operator new that takes a JSGlobalData* to prepare for future arena use. Use raw pointers instead of RefPtr everywhere possible.
  • parser/Parser.cpp: (JSC::Parser::reparseInPlace): Pass the arena in.
  • parser/Parser.h: (JSC::Parser::parse): Updated for name change of parserObjects to parserArena. (JSC::Parser::reparse): Ditto.
  • runtime/FunctionConstructor.cpp: (JSC::extractFunctionBody): Ditto.
  • runtime/JSGlobalData.cpp: (JSC::JSGlobalData::~JSGlobalData): Ditto. (JSC::JSGlobalData::createNativeThunk): Moved arena manipulation into the FunctionBodyNode::createNativeThunk function.
  • runtime/JSGlobalData.h: Tweaked formatting and renamed parserObjects to parserArena.
  • wtf/NotFound.h: Added the usual "using WTF" to this header to match the rest of WTF.
