   Hi,
   what must be done to enable reading of AMD64 corefiles in a gdb running 
   on i386 with --target=amd64?

The necessary support for corefiles needs to be added to
x86-64-linux-tdep.c.  Take a look at i386nbsd-tdep.c for an example.
You'll need to create a `struct core_fns' together with the necessary
support functions, and register it with add_core_fns.  Note that for
the support functions you can't rely on definitions in header files
and such since this is target code.  You'll also need to drop
core-regset.o from NATDEPFILES in x86-64-linux.mh.

Success!
