Simon,

Thanks for getting back to me! I resent the original message below. Please let me know if it still hasn't gone through.

The use case of the new x86_64 stub is the same as the old x86 stub, except it works with newer 64-bit processors. See -
https://sourceware.org/gdb/onlinedocs/gdb/Remote-Stub.html (Notice that there is no 64-bit stub in the list of stubs provided by GDB.)
https://sourceware.org/gdb/onlinedocs/gdb/Debug-Session.html#Debug-Session

Thanks and let me know if you have any further questions!

For years there has been no gdb stub for use with embedded systems
running Intel 64 bit CPUs. This is no longer the case. The new stub is
based on the old i386-stub, but provides support for 64 bit registers
and 64 bit interrupt descriptor table (IDT) entries.

gdb/stubs/ChangeLog:

* x86_64-stub.c: New file.

I somehow don't see the original message (in both my inbox and the web
archive), just your two pings. Can you see it?

Can you provide some explanations for the use case of these stubs, how
they work and how to give them an "hello world" try? I've never used
them, so I don't know anything about them. Having a quick run through
would help.

Thanks,

Simon
