Remove trailing '-' from the last QTDP action packet
|
|
|
7bc85d |
|
|
|
7bc85d |
The has_more predicate in remote_target::download_tracepoint always
|
|
|
7bc85d |
evaluates to true, so the last action packet will be sent with a
|
|
|
7bc85d |
trailing '-'. This patch changes the predicate to remove the last
|
|
|
7bc85d |
trailing '-'.
