/* Printers for the debug target.  Each prints an object of a given
   type to a string that needn't be freed.  Most printers are macros,
   for brevity, but a few are static functions where more complicated
   behavior is needed.

   References to these printers are automatically generated by
   make-target-delegates.  See the generated file target-delegates-gen.c.

   In a couple cases, a special printing function is defined and then
   used via the TARGET_DEBUG_PRINTER macro.  See target.h.

   A few methods still have some explicit targetdebug code in
   target.c.  In most cases this is because target delegation hasn't
   been done for the method; but individual cases vary.  For instance,
   target_store_registers does some special register printing that is
   more simply done there, and target_xfer_partial additionally
   bypasses the debug target.  */
