Subject: [PATCH] Save CS segment register for ljmp instruction
Date: Mon, 12 Oct 2009 02:24:00 -0000	[thread overview]
Message-ID: <1255314282-23062-1-git-send-email-freephp@gmail.com> (raw)

Hi Hui,

I think CS register should be stored for ljmp instruction, but I'm
not pretty sure, please help me confirm it.

Thanks!
