Is it possible to get sign flag equal 1 with these instructions?
movzx ecx, byte ptr[eax]
and ecx, 8000000Fh
jns short loc_401073
There is an and
between the ecx
register and 8000000Fh. In ecx
can be a number in the range 00h-FFh, but I am not sure if it is possible to get SF=1. Could someone help me?
