--- Comment #3 from Simon Marchi <simark at simark dot ca> ---
There are many tools that implement the same protocol as GDBserver, namely the
GDB Remote Protocol:

    https://sourceware.org/gdb/onlinedocs/gdb/Remote-Protocol.html
   
https://www.embecosm.com/appnotes/ean4/embecosm-howto-rsp-server-ean4-issue-2.html

It is just a guess, but it is very likely that ARM's tool implements that
protocol, without using GDBserver.  This allows using GDB as a frontend to
debug, while using whatever they want to do the simulation part.
