These two pointers can never be NULL since they are initialised to a reference of a struct. This became apparent when commit 210a19539447 added a VIR_DEBUG which used both pointers because due to the concise condition the compiler saw that if the "and" part of the condition did short-circuit (and it assumed that can happen) the second variable would not be initialised, but it is used in the debugging message, so the build failed with: In file included from ../src/cpu/cpu_x86.c:27: ../src/cpu/cpu_x86.c: In function ‘virCPUx86DataIsIdentical’: ../src/util/virlog.h:79:5: error: ‘bdata’ may be used uninitialized in this function [-Werror=maybe-uninitialized] Fix this by just assigning the helper pointers and remove the condition altogether.

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
