gdbsx defines own _domctl_hcall instead of using libxc?
Hi Mukesh,
I was auditing uses of set_xen_guest_handle for correctness when I
noticed that gdbsx (specifically tools/debugger/gdbsx/xg/xg_main.c)
defines its own _domctl_hcall and associated helpers instead of using
libxc.
Is there any particular reason for that?
Ian.

gdbsx: xg_main.c:497: xg_resume_n_wait: Assertion `_domain_is_paused()''
failed.
Why would the Assertion failure happen?
Preciate for your reply, thanks in advance.
Best regards.
