    Support for the 9000/[34]00 has several limitations.
      1. Shared libraries are not supported.
      2. The output format from this bfd is not usable by native tools.
      3. Core files are not supported (yet).

    The primary motivation for writing this bfd was to allow use of
    gdb and gcc for host based debugging and not to mimic the hp-ux tools
    in every detail.  This leads to a significant simplification of the
    code and a leap in performance.  The decision to not output hp native
    compatible objects was further strengthened by the fact that the richness
    of the gcc compiled objects could not be represented without loss of
    information.  For example, while the hp format supports the concept of
    secondary symbols, it does not support indirect symbols.  Another
    reason is to maintain backwards compatibility with older implementations
    of gcc on hpux which used 'hpxt' to translate .a and .o files into a
    format which could be readily understood by the gnu linker and gdb.
    This allows reading hp secondary symbols and converting them into
    indirect symbols but the reverse it not always possible.

    Another example of differences is that the hp format stores symbol offsets
    in the object code while the gnu utilities use a field in the
    relocation record for this.  To support the hp native format, the object
    code would need to be patched with the offsets when producing .o files.

    The basic technique taken in this implementation is to #include the code
    from aoutx.h and aout-target.h with appropriate #defines to override
    code where a unique implementation is needed:

    {
        #define a bunch of stuff
        #include <aoutx.h>

        implement a bunch of functions

        #include "aout-target.h"
    }

    The hp symbol table is a bit different than other a.out targets.  Instead
    of having an array of nlist items and an array of strings, hp's format
    has them mixed together in one structure.  In addition, the strings are
    not null terminated.  It looks something like this:

    nlist element 1
    string1
    nlist element 2
    string2
    ...

    The whole symbol table is read as one chunk and then we march thru it
    and convert it to canonical form.  As we march thru the table, we copy
    the nlist data into the internal form and we compact the strings and null
    terminate them, using storage from the already allocated symbol table:

    string1
    null
    string2
    null
 */

/* @@ Is this really so different from normal a.out that it needs to include
   aoutx.h?  We should go through this file sometime and see what can be made
   more dependent on aout32.o and what might need to be broken off and accessed
   through the backend_data field.  Or, maybe we really do need such a
   completely separate implementation.  I don't have time to investigate this
   much further right now.  [raeburn:19930428.2124EST] */
