Hi, I don't know if this is a compiler question or a platform question but it is definitely a programming question.

On the new M$ 64-bit platform released this week, they support ATOMIC operations on 64-bit values.

Were do I find the equivalent ATOMIC functions on LINUX?

In asm-x86_64/atomic.h I can only find operations that work on 32-bit values.

Do I basically have to roll my own versions of these functions?

Is this something someone is looking to add to atomic.h for various platforms?

I have an Itanium system, and in atomic.h there are several functions that utilize longs (eg. 64 bit ). static __inline__ int ia64_atomic64_add (__s64 i, atomic64_t *v) { __s64 old, new; CMPXCHG_BUGCHECK_DECL

do { CMPXCHG_BUGCHECK(v); old = atomic_read(v); new = old + i; } while (ia64_cmpxchg(acq, v, old, new, sizeof(atomic_t)) != old); return new; }

However, while this returns an int eventhough the values are 64-bit. I'm going to email the author. (BTW: This is in SLES9).
