Hi Pedro,
> Is this dependency on host signal defines what is done on other sims?
This was probably added when breakpoint support was being added to this
sim port with reference of the SH port I believe.

Yes Mike, I agree. I have tested it without this hunk and breakpoints seem to
work as expected. Please see below the patch that reverts this in sim.
I am rearranging some code to create cr16-linux-tdep.c file as suggested by Yao
and will post the gdb related patches soon.
Thanks!
