printf of unsigned long long in ARM processors

[Andrés Moré <more dot andres at gmail dot com>]

Hi All,

I'm trying to cross compile some tools to an ARM Xscale processor.
I have a problem regarding the output of printf when passing some
unsigned long long values. I had tested in i386 and ppc32 successfully
but I can't understand this type of behavior in the ARM processor.

Using printk's from linux kernel in kernel-space modules I see the
correct output.
That why I'm writing to this list.

{
      unsigned long long value = 0x1234;

      if (value == (unsigned long long) 0x1234)
        {
          printf("Equal\n");
        }

      printf("%llx\n",value);
      printf("%Lx\n", value);

}

Equal
123400000000
123400000001

I'm compiling with this CFLAGS: "-txscale -mbig-endian" using "-W and
-Wall" with
Please note that the ARM processor is big endian.

I have the following version of gcc and ld.

arm-linux-gnueabi-gcc -v
