Yes, it is used for the dwarf unwinder. I do not know if arm supports 
dwarf, but you can easily find out.

Take this snippet and compile it with gcc -fPIC z.c -fexceptions -S -dA


#include <stdio.h>
extern foo();
main() {
  printf(" back in main\n");
  foo();
  return 10;
}

Then have a look at the .s file and investigate the output. If so, it 
should look similar to the snippet you added in the mail.
