Subject: [PATCH] tools/gdbsx: fix -Wstringop-truncation warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
gcc-8 complains:
gx_main.c: In function 'prepare_stop_reply':
gx_main.c:385:9: error: 'strncpy' output truncated before terminating nul copying 6 bytes from a string of the same length [-Werror=stringop-truncation]
strncpy(buf, "watch:", 6);
^~~~~~~~~~~~~~~~~~~~~~~~~
Since terminating '\0' isn't needed here at all, switch to memcpy.
