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