代码

extern "C" int __libc_start_main(int (*main)(int,char**,char**), int argc, char **argv, void (*init)(void), void (*fini)(void), void (*rtld)(void), void *se){
    if(init) init();
    main(argc, argv, argv+argc+1);
    __asm__ volatile("mov $60,%eax; xor %edi,%edi; syscall");
}
int plus(int a,int b){ return a+b; }
