gdb: Retrieving Descriptions

 
 G.1 Retrieving Descriptions
 ===========================
 
 Target descriptions can be read from the target automatically, or
 specified by the user manually.  The default behavior is to read the
 description from the target.  GDB retrieves it via the remote protocol
 using 'qXfer' requests (qXfer General Query Packets.).  The ANNEX
 in the 'qXfer' packet will be 'target.xml'.  The contents of the
 'target.xml' annex are an XML document, of the form described in 
 Target Description Format.
 
    Alternatively, you can specify a file to read for the target
 description.  If a file is set, the target will not be queried.  The
 commands to specify a file are:
 
 'set tdesc filename PATH'
      Read the target description from PATH.
 
 'unset tdesc filename'
      Do not read the XML target description from a file.  GDB will use
      the description supplied by the current target.
 
 'show tdesc filename'
      Show the filename to read for a target description, if any.
