30 | /* This file provids the (temporary) glue between the Solaris SPARC | |
31 | target dependent code and the machine independent SVR4 /proc | |
32 | support. */ | |
33 | ||
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 | ||
386c036b MK |
43 | Note that a 32-bit GDB won't be able to debug a 64-bit target |
44 | process using /proc on Solaris. */ | |
