That, plus use "(gdb) target sim OPTIONS" where OPTIONS includes
actual activation (not just capability) instructions like
"--trace-insn".  See sim/common/*trace*.

I meant "(gdb) target sim; load; stepi; stepi; stepi; ...", so that
the sim is made to execute one target instruction at a time.

I suggest building a vanilla working cross toolchain first, learning
how to use all the tools, and only after that attempting to port them.
It will take far too long to explain both usage and porting in email.
