29   target dependent code and the machine independent SVR4 /proc
30   support.  */

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