34 data models, the traditional 32-bit data model (ILP32) and the
35 64-bit data model (LP64). The format of /proc depends on the data
36 model of the observer (the controlling process, GDB in our case).

38 data model of the controlling process. If its value is
39 PR_MODEL_LP64, we know that GDB is being compiled as a 64-bit

43 process using /proc on Solaris. */
