When I compile qemu with such as: git clone https://git.qemu.org/git/qemu.git cd qemu git submodule init git submodule update --recursive ./configure make There is error log: /home/LiKaige/qemu/target/arm/translate-a64.c: In function ‘disas_ldst’: /home/LiKaige/qemu/target/arm/translate-a64.c:3392:5: error: ‘fn’ may be used uninitialized in this function [-Werror=maybe-uninitialized] fn(cpu_reg(s, rt), clean_addr, tcg_rs, get_mem_index(s), ^ /home/LiKaige/qemu/target/arm/translate-a64.c:3318:22: note: ‘fn’ was declared here AtomicThreeOpFn *fn; ^ cc1: all warnings being treated as errors So, add an initiallization value NULL for fn to fix this.
