ELF64 core dumps on 32 bit platforms

[Bernhard Walle]

Hello,

GDB cannot analyse 64 bit core dumps on 32 bit platforms. This makes
sense for kernel dumps on machines that support a larger physical than
virtual address space, like i686 and PAE. Of course, there's crash, a
special tool for kernel dumps that is based on GDB 6.1 which can
analyse this, but it does memory handling independent of GDB.

The question is: Is it a limitation of the current GDB design that
ELF64 core dumps cannot be handled on 32 bit platforms or would it be
relatively easy to implement?


Thanks,
   Bernhard
