Performance? Homogenicity?
I saw there's a "general" rule that the runtime lib should be written in
JS, but this is a border line case. Especially marshaling functions like
function GetStackFrames(raw_stack) {
var frames = new InternalArray();
var sloppy_frames = raw_stack[0];
for (var i = 1; i < raw_stack.length; i += 4) {
var recv = raw_stack[i];
var fun = raw_stack[i + 1];
var code = raw_stack[i + 2];
var pc = raw_stack[i + 3];
var pos = %FunctionGetPositionForOffset(code, pc);
sloppy_frames--;
frames.push(new CallSite(recv, fun, pos, (sloppy_frames < 0)));
}
return frames;
}
