28 Support for the 9000/[34]00 has several limitations.
29 1. Shared libraries are not supported.
30 2. The output format from this bfd is not usable by native tools.
32 The primary motivation for writing this bfd was to allow use of
33 gdb and gcc for host based debugging and not to mimic the hp-ux tools
34 in every detail. This leads to a significant simplification of the
35 code and a leap in performance. The decision to not output hp native
36 compatible objects was further strengthened by the fact that the richness
37 of the gcc compiled objects could not be represented without loss of
38 information. For example, while the hp format supports the concept of
39 secondary symbols, it does not support indirect symbols. Another
40 reason is to maintain backwards compatibility with older implementations
41 of gcc on hpux which used 'hpxt' to translate .a and .o files into a
42 format which could be readily understood by the gnu linker and gdb.
43 This allows reading hp secondary symbols and converting them into
44 indirect symbols but the reverse it not always possible.
46 Another example of differences is that the hp format stores symbol offsets
47 in the object code while the gnu utilities use a field in the
48 relocation record for this. To support the hp native format, the object
49 code would need to be patched with the offsets when producing .o files.
51 The basic technique taken in this implementation is to #include the code
52 from aoutx.h and aout-target.h with appropriate #defines to override
53 code where a unique implementation is needed:
56 #define a bunch of stuff
59 implement a bunch of functions
61 #include "aout-target.h"
64 The hp symbol table is a bit different than other a.out targets. Instead
65 of having an array of nlist items and an array of strings, hp's format
66 has them mixed together in one structure. In addition, the strings are
67 not null terminated. It looks something like this:
75 The whole symbol table is read as one chunk and then we march thru it
76 and convert it to canonical form. As we march thru the table, we copy
77 the nlist data into the internal form and we compact the strings and null
78 terminate them, using storage from the already allocated symbol table:
86 /* @@ Is this really so different from normal a.out that it needs to include
87 aoutx.h? We should go through this file sometime and see what can be made
88 more dependent on aout32.o and what might need to be broken off and accessed
89 through the backend_data field. Or, maybe we really do need such a
90 completely separate implementation. I don't have time to investigate this
91 much further right now. [raeburn:19930428.2124EST] */
92 /* @@ Also, note that there wind up being two versions of some routines, with
