Are these two instructions performing the same operation:
mov $0x80000000, %esp
mov $0x80000000, (%esp)
mov $0x80000000, 0(%esp)
Also, what does this instruction do:
mov (%eax), %eax
1st:
esp= 0x800000002nd and 3rd: 4 bytes of memory at address from
esp= 0x80000000.Last:
eax= 4 bytes of memory at address fromeax.Btw, the
lsuffix is probably missing. I usually see these instructions asmovl, meaning move a long value (=4 bytes).Find a (g)as or AT&T assembly syntax tutorial. You’re not the first to ask this kind of question.
