Paul Traina 7929041ebe Import GDB in its full glory (all 25mb). We'll put it on a diet once it's 
fully registered.

(This is the second try, the first import ignored .info files but not .info-*
 files, for some reason.  I'm going to make this consistent.)

hpux native ------------> | |
| hp300hpux bfd | ----------> hpux w/gnu ext
hpux w/gnu extension ----> | |
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.
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] */
/* @@ Also, note that there wind up being two versions of some routines, with
different names, only one of which actually gets used. For example:
slurp_symbol_table
swap_std_reloc_in
slurp_reloc_table
get_symtab
get_symtab_upper_bound
canonicalize_reloc
mkobject
This should also be fixed. */
