+ 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
