Stand-alone sis has a gdb server, so the gdb debug environment should be identical. In gdb, just do target extended-remote localhost:1234 instead of target sim. Keeping sis inside gdb has a number of problems:

* The sis patches will never be accepted into the gdb mainline

* We will have to maintain a patch set for each gdb version

* Making new versions of sis is cumbersome since we have to provided patches rather than just a git repo

* No support for data watchpoints in the gdb sim interface

* Build problems for Cygwin

I also like the simplicity of a built-in simulator, but a stand-alone sim is just so much easier to develop and maintain...
