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