/* 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] */

different names, only one of which actually gets used. For example:
