+
+ * mi/mi-main.c (mi_cmd_data_write_memory): Handle additional
+ parameter COUNT, for pattern filling of memory regions.
+ * NEWS: Mention it.
+
2012-11-13 Markus Metzger <markus.t.metzger@intel.com>
* disasm.h (DISASSEMBLY_FILENAME): New macro.
** The data-disassemble command response will include a "fullname" field
containing the absolute file name when GDB can determine it and source
has been requested.
+ ** New optional parameter COUNT added to the "-data-write-memory-bytes"
+ command, to allow pattern filling of memory areas.
*** Changes in GDB 7.5

+
+ * gdb.texinfo (GDB/MI Data Manipulation): Document new optional
+ parameter "count" of -data-write-memory-bytes, and add an example.
