Thanks so far. I think we'll be able to delve in next month.

It wasn't made generic but there's one that was *intended* to be made
generic in the hal/v85x ports. Search for CYGDBG_HAL_V850_ICE, and in
particular look at hal/v85x/v850/current/src/v850_ice.cxx.

There's also one for the ARM at hal/arm/arch/current/src/arm_stub.c but
that isn't quite as good as it requires stubs to be included in
applications.

Ideally such support should be built into the eCos port! If it's for an
existing target, contributing it back to the community would be the best
thing for users. Of course the support would want to be default off for
users who don't need it.
