Hi Eli,
Ok!
Register reading and writing need some support from the OS, and vary from OS to OS. In this sense we have done part of the whole work on the i386-tdep.c and part on the i386-tdep-linux.c.
Regards,
-Fred

I'm sorry to insist, but that's exactly my question: why were the changes done in Linux-specific i386-tdep-linux.c etc., and not in the CPU-specific i386-tdep.c etc.? These registers are specific to a CPU, not to an OS, aren't they?
