Our atomic increment (virAtomicIntInc) uses (if available) gcc __sync_add_and_fetch builtin. In qemu driver though, we'd profit more from __sync_fetch_and_add builtin. To keep it simplistic, this patch adjusts qemu driver initialization rather than adding a new atomic increment macro.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
