- 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.
- 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] */
- /* @@ 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. */
