--- Comment #1 from [email protected] --- Ideally, a fix would also handle partial or complete argument reordering -- so if first() called second(b, a), then all the stack munging could just be straight 'xchg esi, edi'. (However, making that work in more complicated functions that pass many arguments--some from their own arguments, others from local variables--would probably require a lot more effort, and mess with the register allocator quite a bit: is it worth it to place this local variable in a register instead of on the stack, knowing that means clobbering that register so it will have to be restored later?) --
