  32 /* Solaris 10 (Solaris 2.10, SunOS 5.10) and up support two process
  33    data models, the traditional 32-bit data model (ILP32) and the
  34    64-bit data model (LP64).  The format of /proc depends on the data
  35    model of the observer (the controlling process, GDB in our case).
  36    The 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    Note that a 32-bit GDB won't be able to debug a 64-bit target
  42    process using /proc on Solaris.  */
