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