I was about to say "why can't it disassemble backwards", but that's not rea= lly doable on variable-length opcodes. If it can't be optimised, then perhaps there could be some kind of "function start cache" so that the cost is only paid once? Probably needs some user feedback also? --=20 You are receiving this mail because: You are on the CC list for the bug.=
