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