After updating my toolchain to:
aarch64-linux-gnu-gcc (Debian 13.2.0-2) 13.2.0
I hit compilation error:
arm/kvm-cpu.c: In function ‘kvm_cpu__arch_init’:
arm/kvm-cpu.c:119:41: error: ‘target’ may be used uninitialized [-Werror=maybe-uninitialized]
119 | vcpu->cpu_compatible = target->compatible;
| ~~~~~~^~~~~~~~~~~~
arm/kvm-cpu.c:40:32: note: ‘target’ was declared here
40 | struct kvm_arm_target *target;
| ^~~~~~
target is guaranteed to be initialized, as targets would be registered
from other compilation units (arm/aarch(32|64)/arm-cpu.c).
Initializing the variable to NULL is sufficient to silence the compiler.
