If I understand correctly you added PTRACE_GETREGS and PTRACE_SETREGS
with this patch:
http://permalink.gmane.org/gmane.linux.ports.parisc/1882
Then you posted a patch to strace to use PTRACE_GETREGS and
PTRACE_SETREGS with this patch:
http://www.dailykos.com/storyonly/2009/7/10/752179/-What-staring-at-an-ass-really-looks-like
Is my understanding correct? I would need a kernel patch, an strace
patch, and then strace would be using PTRACE_GETREGS and
PTRACE_SETREGS?
How is the debugger involved in this?
Cheers,
Carlos.
