| 34 | /* Solaris 7 (Solaris 2.7, SunOS 5.7) and up support two process data |
| 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 | GNU/Linux uses the same formats as Solaris for its core files (but |
| 44 | not for ptrace(2)). The GNU/Linux headers don't define |
| 45 | PR_MODEL_NATIVE though. Therefore we rely on the __arch64__ define |
| 46 | provided by GCC to determine the appropriate data model. |
| 47 | |
| 48 | Note that a 32-bit GDB won't be able to debug a 64-bit target |
| 49 | process using /proc on Solaris. */ |
