# Test inferior can stop at its very first instruction, usually "_start".
# Dynamic executables have first instruction in ld.so.
# 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.
