reading register information from corefile

["Harsha HS" <harsha dot hs dot 81 at gmail dot com>]

Hello,

 I am trying to build a corss gdb for mips r3k architecture. I am able
to load any mips executable on gdb and can debug the same

But when i try to load core file i get the message that "GDB can't
read core files on this machine".

Can u please help me by pointing to the code where I have to add to 
struct target_ops the mips core file format and also the note section
in the core file to read the register information for a standalone
embedded application.

thanks
