- Subject: [PATCH 2/4] Remove trailing '-' from the last QTDP action packet
- References: <20180620210855.6385-1-pedromfc@linux.vnet.ibm.com>
The has_more predicate in remote_target::download_tracepoint always
evaluates to true, so the last action packet will be sent with a
trailing '-'. This patch changes the predicate to remove the last
trailing '-'.
gdb/ChangeLog:
YYYY-MM-DD Pedro Franco de Carvalho <pedromfc@linux.vnet.ibm.com>
* remote.c (remote_target::download_tracepoint): Fix the has_more
predicate in the QTDP action list iteration.
