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