Hi,
I was given your email as address for patches to gdb. Please advice if you
are not  the correct person.

Problem.

        Gdb version 5.3 target h8300-coff. Machine h8300h. Simulator

Demonstration of fault.

        set machine h8300h
        target sim
        Gdb Abort!
Cause of fault.
        Incorrect definition of number of machine registers in tm-h8300.h
Patch
        diff -c tm-h8300.h tm-h8300.h-orig

Fix is alpha as there is another definition of NUM_REGS in h8300-tdep.c ,
these two need to be merged and integrated into the gdb definitions for h8300
registers.

Can you download a GDB 6.0 pre-release (GDB 5.3.91) from 
ftp://sources.redhat.com/pub/gdb/snapshots/branch/

many things h8300 related were fixed after GDB 5.3 was released.
