Hello,

It's documented in the GDB documentation:
http://sourceware.org/gdb/current/onlinedocs/gdb_16.html#SEC154

SUSE uses the split out debug information, starting from SLES 10 (also
openSUSE).  It makes sense on architectures that don't need a
separate, bootable kernel image (like x86_64 and i586) but can boot
the ELF file directly such as PPC and IA64.


Thanks,
   Bernhard
