A naked "run" command doesn't work when testing against
gdbserver with --target_board=native-gdbserver.

Is "run" important here?  Could this use runto_main + "continue" instead?

As long as the test run doesn't assert, we could instead use
"runto_main + "continue". Thanks for pointing this out.

Also, the comment at the top of the file says:

  # This test checks that GDB does not alter watchpoints set by an inferior.
  # It sets a watchpoint on memory then writes to the watched memory.
  # It will exit with 1 if the watchpoint is not reached.

But I couldn't spot where that "exit with 1" happens in the .c file.

You are right, it should be "exit with 2".

Also, when that happens, we're issuing a pass, as seen above.
Is that intended?

"Exit with 1" could happen if the PTRACE_SETREGSET call should
fail which is ok as long as it doesn't cause assertion.

Thanks for your comments.


Thanks,
Pedro Alves
