32 | target dependent code and the machine independent SVR4 /proc | |
33 | support. */ | |
34 | ||
35 | /* Solaris 7 (Solaris 2.7, SunOS 5.7) and up support two process data | |
36 | models, the traditional 32-bit data model (ILP32) and the 64-bit | |
37 | data model (LP64). The format of /proc depends on the data model | |
38 | of the observer (the controlling process, GDB in our case). The | |
39 | Solaris header files conveniently define PR_MODEL_NATIVE to the | |
40 | data model of the controlling process. If its value is | |
41 | PR_MODEL_LP64, we know that GDB is being compiled as a 64-bit | |
42 | program. | |
43 | ||
44 | GNU/Linux uses the same formats as Solaris for its core files (but | |
45 | not for ptrace(2)). The GNU/Linux headers don't define | |
46 | PR_MODEL_NATIVE though. Therefore we rely on the __arch64__ define | |
47 | provided by GCC to determine the appropriate data model. | |
48 | ||
49 | Note that a 32-bit GDB won't be able to debug a 64-bit target | |
50 | process using /proc on Solaris. */ | |
