/* Solaris 7 (Solaris 2.7, SunOS 5.7) and up support two process data
36
   models, the traditional 32-bit data model (ILP32) and the 64-bit
37
   data model (LP64).  The format of /proc depends on the data model
38
   of the observer (the controlling process, GDB in our case).  The
39
   Solaris header files conveniently define PR_MODEL_NATIVE to the
40
   data model of the controlling process.  If its value is
41
   PR_MODEL_LP64, we know that GDB is being compiled as a 64-bit
42
   program.
43
 
44
   GNU/Linux uses the same formats as Solaris for its core files (but
45
   not for ptrace(2)).  The GNU/Linux headers don't define
46
   PR_MODEL_NATIVE though.  Therefore we rely on the __arch64__ define
47
   provided by GCC to determine the appropriate data model.
48
 
49
   Note that a 32-bit GDB won't be able to debug a 64-bit target
50
   process using /proc on Solaris.  */
