Solaris BCP (the part of Solaris which allows it to run SunOS4
a.out files) throws in another wrinkle. Solaris does not fill
in the usual a.out link map structures when running BCP programs,
the only way to get at them is via groping around in the dynamic
linker.
The dynamic linker and it's structures are located in the shared
C library, which gets run as the executable's "interpreter" by
the kernel.
Note that we can assume nothing about the process state at the time
we need to find these structures. We may be stopped on the first
instruction of the interpreter (C shared library), the first
instruction of the executable itself, or somewhere else entirely
(if we attached to the process for example).
