I am reading some lock-free shared data-structures currently and am 
planning to implement some of them. They are mostly built on the atomic 
CAS (compare and swap) operation. I am just wondering how can I use the 
hardware CAS instruction? I googled for some time, but it seems there is 
very little information on this. I am mainly using C++, pthread library 
and the GNU g++ compiler and how can I use the hardware CAS instruction 
on Intel/Linux, Sparc/Solaris, and MIPS/IRIX systems. Can someone 
provide some examples or point me to the right place? Thanks in advance.
