Seeing HN utterly baffled how Rosetta 2 JIT compiles a JIT compiler is pretty priceless

it doesnt seem that difficult in concept, just a little complex to work out all the bugs, but they're apple, they can do a lot of testing

It's... Not that complicated given the other considerations you have to deal with anyway, like x86 binaries not having unambiguous parses

t-they don't???

so if you want some real fun... call rand test eax, 1 jz 1f+1 1: add ax, ax If rand returns an odd value, that executes "add ax, ax". If it returns an even value, it skips the first byte of the instruction, which will be 66h (operand size prefix), so it becomes "add eax, eax"
