Re: [Xen-devel] [PATCH] gdbserver-xen: fix corefile access

Sorry, scratch that. I think they can just be merged into one

Do you think it would be better to pass the isfile flag in the form
of PTRACE_ATTACH|XC_PTRACE_FILE as the third argument to xc_ptrace,
or parhaps use the last argument to xc_ptrace, edata (or perhaps the
second last one, eaddr), which are unused for ATTACH.
Having xc_ptrace_thread/xc_ptrace_core *internally* in libxenctrl would
be fine, but there should be only one public function (xc_ptrace). You
can update PTRACE_ATTACH as you wish -- I guess adding a new ptrac
ecommand would be cleaned: PTRACE_ATTACH_COREFILE would be okay.
And yes, I expect you can give the same treatment to xc_waitdomain. It
probably should be a no-op when debugging a core file (although
currently it loads the core file state into memory, which is weird but
I guess works okay).
