reading register information from corefile

[Harsha HS]

I am trying to build a corss gdb for mips r3k architecture. When i try
to load core file i get the message that "GDB can't read core files on
this machine", as the function find_target_core returns NULL.

find_target_core scans the struct target_ops for the core_stratum and
returns the appropriate target structure.

Can u please help me on how to initialize the struct target_ops with
the relevent values to support the loading of the core file specific
to mips target.

thanks,
