Subject: [PATCH v2 18/19] write_pieced_value: Notify memory_changed observers
Date: Tue, 09 May 2017 17:59:00 -0000 [thread overview]
Message-ID: <1494352015-10465-19-git-send-email-arnez@linux.vnet.ibm.com> (raw)
In-Reply-To: <1494352015-10465-1-git-send-email-arnez@linux.vnet.ibm.com>
So far write_pieced_value uses write_memory when writing memory pieces to
the target. However, this is a case where GDB potentially overwrites a
watchpoint value. In such a case write_memory_with_notification should be
used instead, so that memory_changed observers get notified.
gdb/ChangeLog:
* dwarf2loc.c (write_pieced_value): When writing the data for a
memory piece, use write_memory_with_notification instead of
write_memory.
