Hmm, this seems to be working only with gdb 5.3. How can I do this
with -current's gdb 6.5?
GNU gdb 6.5
(gdb) target kcore netbsd.1.core
Undefined target command: "kcore netbsd.1.core". Try "help target".
(gdb) help target
target async -- Use a remote computer via a serial line
target child -- Unix child process (started by the "run" command)
target core -- Use a core file as a target
target exec -- Use an executable file as a target
target extended-async -- Use a remote computer via a serial line
target extended-remote -- Use a remote computer via a serial line
target kvm -- Use a kernel virtual memory image as a target
target remote -- Use a remote computer via a serial line
If fifty million people say a foolish thing,
it is still a foolish thing.
