| 35 | models, the traditional 32-bit data model (ILP32) and the 64-bit |
| 36 | data model (LP64). The format of /proc depends on the data model |
| 37 | of the observer (the controlling process, GDB in our case). The |
| 38 | Solaris header files conveniently define PR_MODEL_NATIVE to the |
| 39 | data model of the controlling process. If its value is |
| 40 | PR_MODEL_LP64, we know that GDB is being compiled as a 64-bit |
| 41 | program. |
| 42 | |
| 43 | Note that a 32-bit GDB won't be able to debug a 64-bit target |
| 44 | process using /proc on Solaris. */ |
