I would think that an implementation of these is included in the
Intel GNU/960 toolset. You will have to check there. I believe
the licensing is appropriate for including them in newlib if you
do the integration work. Be careful reading the license to make
FYI there are i960 CPU specific routines in machine/i960 but the
Makefile does not references them. There are mem* and str* routines
that are not built but included. I don't know why.
