Hi,
The latest version of gdb seems to break the CR16 simulator which had been 
working till version 7.2.
I am not able to figure out the reason why the attached hunk (nltvals.def) has
been removed from the sources, maybe regenerate missed it out.
The original patch was posted in 2008 and this hunk was part of 7.2 sources.
http://sourceware.org/ml/gdb-patches/2008-02/msg00385.html
I have attached a patch that places the original code. Please let me know if
this is OK.

We are also working on adding gdb and gdbserver support to this target and 
plan to post the patches soon. Parts of the simulator have been modified to 
add breakpoint support. These will be posted separately.

Thanks & Best Regards,
Kaushik Phatak
