  32    support.  */

  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    Note that a 32-bit GDB won't be able to debug a 64-bit target
  44    process using /proc on Solaris.  */
