Hi,
I'd like to help with debugging the sparc64 target (to get HelenOS
run on it). I'd like to use gdb for that purpose, however, I get
the following error when I try to connect to qemu from gdb:

Is this a known issue? Is there a workaround for this?
The qemu version I am running is trunk, the host is
an ordinary ia32 system.
Thanks,
Jakub

The register size is still incorrect (32 bits) in the GDB you
produced. Also I can't make a working cross-gdb. The problem is on GDB
side: on Sparc64 OpenBSD, where everything is 64 bits, there is no
problem and the protocol matches what Qemu produces.
I'd be happy to be proven wrong, though. Currently my OpenBSD setup is
slightly broken, so this comes from memory.

Ok, I was able to solve this problem by:
set architecture sparc:v9
Thanks,
