+/* 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.  */
