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. | |
