Hi
Reference:http://sources.redhat.com/ml/gdb-patches/2004-06/msg00428.html
In the latest GDB(gdb+dejagnu-20040630) snap shot, the "info f" problem described in the above link is fixed. Referring through the links you have suggested, it is evident that h8300 target is not in the list of the new GDB frame structure. Is it possible to know what should be done from our side to update H8300 targets to the new frame work? Can you suggest how to go about it?
Thanks in advance.

Are you sure this patch is against 6.1 or a current GDB? The function
h8300_frame_init_saved_regs has a void return type.
Also, you might want to read over:
Post GDB 6.2, require new frame code
http://sources.redhat.com/ml/gdb/2004-06/msg00199.html
As this will affect the h8/300.
