* Store arguments in the stack frame before the locals/tempsErik Verbruggen2017-08-031-24/+4
| | | | | | | | | | All escaping arguments will still be loaded/stored from/to the CallData, but this is not the common case. In a subsequent patch we can make the caller prepare the stack frame, and for the common case we don't even need to copy arguments around.

* Introduce an accumulator in the interpreter, and change instructionsErik Verbruggen2017-08-021-100/+86
| | | | | | | | | | | | This reduces the number of stores to the stack (for which we need a write-barrier in the future) by keeping the last calculated value in the accumulator register (which is a local variable). In the future we might want to collapse certain common instruction patterns into a super-sized instruction.

| | | | | | | | | The Param struct is now internal to the interpreter loop. It can be removed in a second step so we can directly access constants/temporaries/locals/arguments. Change-Id: I47ecbfe7508f352a8f212af48461dc92b35f4695 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>

* Switch over to new JS call setupLars Knoll2017-06-291-5/+6
| | | | | | | | | | | | | | | | 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>
