rugxulo: Those are four different instructions:
Code: loopw word label ; uses CX and IP, no prefix in 16-bit mode loopw dword label ; uses CX and EIP, prefix 66h in 16-bit mode loopd word label ; uses ECX and IP, prefix 67h in 16-bit mode loopd dword label ; uses ECX and EIP, both 66h and 67h prefixes in 16-bit mode See also the announcement notes of the fasm's version that introduced the correction of jumps handling. PS. When I write "uses IP", it means actually that high-order 16 bits of EIP get zeroed. |
