Test loop (v2)

Revision 2 of this benchmark created on

Setup

let CONVERTOR = new BigInt64Array(1)

function __lesser__(i, end){
	return i.value < end.value;
}

function __impl_add__(i, step) {
	i.value += step.value
	return {type:"int", value: i.value}
}
function __mod__(i, step) {
	return {type:"int", value: i.value % step.value }
}1
