  33 /* Solaris 7 (Solaris 2.7, SunOS 5.7) and up support two process data
  34    models, the traditional 32-bit data model (ILP32) and the 64-bit
  35    data model (LP64).  The format of /proc depends on the data model
  36    of the observer (the controlling process, GDB in our case).  The
  37    Solaris header files conveniently define PR_MODEL_NATIVE to the
  38    data model of the controlling process.  If its value is
  39    PR_MODEL_LP64, we know that GDB is being compiled as a 64-bit
  40    program.
  41
  42    Note that a 32-bit GDB won't be able to debug a 64-bit target
  43    process using /proc on Solaris.  */
