/* 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. */
