The command is info as Go to Machine Dependencies, then i386-Dependent, then i386-Memory. There you will see that the AT&T syntax is DISP(BASE, INDEX, SCALE) DISP is an integer. An example is movl $0, -4(%ebp) which would store 32 bits of zero at the memory location starting 4 bytes negative from the address in the ebp register. (This instruction does not use INDEX or SCALE.) Linux uses a flat memory model, so you don't need to worry about the segmentation registers if you run your program under Linux.
Thank you Robert Plantz for your wonderful insight. --STeve _________________________________________________________________Off to school, going on a trip, or moving?
