From just looking at the bytecodes naively, it looks like a "pushTemp: 0" is much slower than a "pushRcvr: 0" + a "pushConstant: 1.0" + "send: *". Anyone know what's exactly going on? Is there an easy way to print the generated native code? I'm just curious, not a big deal.<div><br></div><div>Thanks,<div>Luciano</div></div></div>
