19# If we're using a stub, we'll already be debugging a live program and
20# stopped at the entry point when we connect, and so the runto below
21# will issue a "continue", which always skips any breakpoint at PC.
22# When testing with a native target (or some other target that supports
23# "run"), runto will do a "run", which first creates the process,
24# leaving the PC at the entry point, just like the stub case, but then
25# continues the process with the equivalent of "jump *$PC", which
26# triggers any breakpoint at $PC.  The latter is what we want to test.
