/* When handling shared libraries, GDB has to find out the pathnames
of all shared libraries that are currently loaded (to read in their
symbols) and where the shared libraries are loaded in memory
(to relocate them properly from their prelinked addresses to the
current load address).
Under OSF/1 there are two possibilities to get at this information:
1) Peek around in the runtime loader structures.
These are not documented, and they are not defined in the system
header files. The definitions below were obtained by experimentation,
but they seem stable enough.
2) Use the libxproc.a library, which contains the equivalent ldr_*
routines. The library is documented in Tru64 5.x, but as of 5.1, it
only allows a process to examine itself. On earlier versions, it
may require that the GDB executable be dynamically linked and that
NAT_CLIBS include -lxproc -Wl,-expect_unresolved,ldr_process_context
for GDB and all applications that are using libgdb.
We will use the peeking approach until libxproc.a works for other
processes. */

in that case.
For a dynamically bound executable, this first instruction is somewhere
in the rld, and the actual user executable is not yet mapped in.
We continue the inferior again, rld then maps in the actual user
executable and any needed shared libraries and then sends
itself a SIGTRAP.
At that point we discover the names of all shared libraries and
read their symbols in.

This code does not properly handle hitting breakpoints which the
user might have set in the rld itself. Proper handling would have
to check if the SIGTRAP happened due to a kill call.
