__break2

 Implements the Alpha __PAL_GENTRAP and __PAL_BUGCHK built-in
 functions on OpenVMS I64 systems.

 The __break2 function is equivalent to the __break function with
 the second parameter passed in general register 17:

 R17 = __R17_value; __break (__break_code);

 Syntax:

      void __break2 (__Integer_Constant __break_code, unsigned
      __int64 __r17_value);
