[avr-gcc-list] gdb-5.1-avr-patch-0.0-pre9 is available

[Theodore A. Roth]

I've just uploaded the gdb-5.1-avr-patch-0.0-pre9 patch for gdb-5.1.

New in this patch is a fix which allows gdb to correctly convert function
pointer addresses from target instruction space (word based) to gdb memory
space (byte based).

For example, if bar is a pointer to function foo(), `print bar` will
correctly print the address of bar. 

Thanks to Ken Restivo for notifying me of the problem.

There is still a known problem with gdb dereferencing zero pointer. I'm 
looking into this, but a solution is not obvious to me at this time. If 
anyone has any insight on this, I'd appreciate it.

Lastly, Marek Michalkiewicz noted that avr-gdb is rather fragile with 
respect to changing the code generated by gcc/gas because of the scanning 
of opcodes. I would tend agree with him. I took the scanning code directly 
from Denis Chertykov's work (or whoever did the 5.0 port) so I haven't 
given much thought to how to this. I am willing to pursue this, but will 
need some help from the community on how this should be approached.
