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
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
+ 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.
#include <aoutx.h>

#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
