hi all

swapping two variables using xor can be as follows
b = a ^ b
a = b ^ a
b = a ^ b
i've been given an assigment to do a swap faster than above and
without using three variables ( on a linux box over i80x86)? I was
wondering howz that possible? Any help will be highly
appreciated......
regards
waqas
