Hello,

reading from the manual I see that atomic instructions
(like lock inc, etc. on x86) are not supported by valgrind
in the sense of being emulated in a correct way.

What is the technical reason for this? Are there any
plans to correctly handle these instructions? What
is the technical difference between handling these and
handling pthread's mutexes? Can't valgrind put something
like fake mutexes 'around' these atomic variables whenever
such an operation is used?

Thanks for some insights here,

regards!

Joerg
