Atomic locks

hi all ,
(back!.. last visited 2009!.. hopefully , we are still active here :) )
I just want to double check

in MSVC we can use interlock ops for atomic syncs ( most of the functions support both amd and intel, if i didn't miss any thing)

but now I have to conver some of those functions to linux server .. so was doing some research and came accros http://gcc.gnu.org/onlinedocs/gcc-4....-Builtins.html .... but those look like they are only supported by intel processor ?

and also I came accros TransactionalMemory .. is that same thing ?

I dont believe those should be dependent on just Intel processors. Do you have access to a computer with an AMD cpu? In that case you could just compile a small test-application.
