In function ‘open’:
    nolibc/sysroot/arm/include/sys.h:919:23: warning: ‘mode_t’ {aka ‘short unsigned int’} is promoted to ‘int’ when passed through ‘...’
      919 |   mode = va_arg(args, mode_t);
          |                       ^
    nolibc/sysroot/arm/include/sys.h:919:23: note: (so you should pass ‘int’ not ‘mode_t’ {aka ‘short unsigned int’} to ‘va_arg’)
    nolibc/sysroot/arm/include/sys.h:919:23: note: if this code is reached, the program will abort
