| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | And changed the namespace of those classes to QV4::Compiler. ScanFunctions should over time also move into its own file. Change-Id: If084acea4a9a20b9c79ad47dac19e02dc720e098 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Differences: - push parameters on the stack, including space for CallData members - call instructions calculate the argument start - use temp space above the calldata to evaluate arguments - fewer temporaries are needed when a call is done while generating the arguments of another call - when calling the function, the js stack space above the callData is not used, allowing for optimizations in the future - Array and ObjectLiteral use the same mechanism Change-Id: Id100fa06f12cc9d941b0f90b0b81b8270a8e4f5d Reviewed-by: Erik Verbruggen <erik.verbruggen@qt.io> Reviewed-by: Lars Knoll <lars.knoll@qt.io>
