gdb: Overloading support for Ada

 
 15.4.10.4 Overloading support for Ada
 .....................................
 
 The debugger supports limited overloading.  Given a subprogram call in
 which the function symbol has multiple definitions, it will use the
 number of actual parameters and some information about their types to
 attempt to narrow the set of definitions.  It also makes very limited
 use of context, preferring procedures to functions in the context of the
 'call' command, and functions to procedures elsewhere.
 
    If, after narrowing, the set of matching definitions still contains
 more than one definition, GDB will display a menu to query which one it
 should use, for instance:
 
      (gdb) print f(1)
      Multiple matches for f
      [0] cancel
      [1] foo.f (integer) return boolean at foo.adb:23
      [2] foo.f (foo.new_integer) return boolean at foo.adb:28
      >
 
    In this case, just select one menu entry either to cancel expression
 evaluation (type '0' and press <RET>) or to continue evaluation with a
 specific instance (type the corresponding number and press <RET>).
 
    Here are a couple of commands to customize GDB's behavior in this
 case:
 
 'set ada print-signatures'
      Control whether parameter types and return types are displayed in
      overloads selection menus.  It is 'on' by default.  See
      Overloading support for Ada.
 
 'show ada print-signatures'
      Show the current setting for displaying parameter types and return
      types in overloads selection menu.  SeeOverloading support for
      Ada.
