/* This file provids the (temporary) glue between the Solaris x86
   target dependent code and the machine independent SVR4 /proc
   support.  */

/* Solaris 10 (Solaris 2.10, SunOS 5.10) and up support two process
   data models, the traditional 32-bit data model (ILP32) and the
   64-bit data model (LP64).  The format of /proc depends on the data
   model of the observer (the controlling process, GDB in our case).
   The Solaris header files conveniently define PR_MODEL_NATIVE to the
   data model of the controlling process.  If its value is
   PR_MODEL_LP64, we know that GDB is being compiled as a 64-bit
   program.

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