/* This file provids the (temporary) glue between the Solaris SPARC

   target dependent code and the machine independent SVR4 /proc

   support.  */

/* Solaris 7 (Solaris 2.7, SunOS 5.7) 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.

   GNU/Linux uses the same formats as Solaris for its core files (but

   not for ptrace(2)).  The GNU/Linux headers don't define

   PR_MODEL_NATIVE though.  Therefore we rely on the __arch64__ define

   provided by GCC to determine the appropriate data model.

   Note that a 32-bit GDB won't be able to debug a 64-bit target

   process using /proc on Solaris.  */
