You are "sure"? In the sense that you "feel" it has to be like that, or in the sense that you *know* what you're talking about? :)

Not general purpose registers, no.

See above.

There are still only *7* general purpose registers (eax, ebx, ecx, edx, esi, edi, ebp). There's another register, ESP, which is the stack pointer and thus can't properly be used for other things, and ebp is generally used as stack frame, but it's not necessary to use it like that and that's why I included it in the "free list" of general purpose registers. |
