Description Cameron Zwarich (cpst) 2008-08-17 13:01:41 PDT
After we added the loop opcodes, I wanted to remove op_jless, as we now have op_loop_if_less. It will only be used when less is inside of a logical operator, which doesn't really justify its continued existence. Removing it was originally a random slowdown on SunSpider, but now it's a 0.1% speedup.
