Title:
openrisc_sim.c:87:42: error: 'cpu_irqs[0]' may be used uninitialized
in this function [-Werror=maybe-uninitialized]
Status in QEMU:
New
Bug description:
I see the warning since gcc10:
static void openrisc_sim_init(MachineState *machine):
...
qemu_irq *cpu_irqs[2];
...
serial_mm_init(get_system_memory(), 0x90000000, 0, serial_irq,
115200, serial_hd(0), DEVICE_NATIVE_ENDIAN);
I would initialize cpu_irqs[2] with {}.
