25 hpux w/gnu extension ----> | |
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.
31 3. Core files are not supported (yet).
33 The primary motivation for writing this bfd was to allow use of
34 gdb and gcc for host based debugging and not to mimic the hp-ux tools
35 in every detail. This leads to a significant simplification of the
36 code and a leap in performance. The decision to not output hp native
37 compatible objects was further strengthened by the fact that the richness
38 of the gcc compiled objects could not be represented without loss of
39 information. For example, while the hp format supports the concept of
40 secondary symbols, it does not support indirect symbols. Another
41 reason is to maintain backwards compatibility with older implementations
42 of gcc on hpux which used 'hpxt' to translate .a and .o files into a
43 format which could be readily understood by the gnu linker and gdb.
44 This allows reading hp secondary symbols and converting them into
45 indirect symbols but the reverse it not always possible.
47 Another example of differences is that the hp format stores symbol offsets
48 in the object code while the gnu utilities use a field in the
49 relocation record for this. To support the hp native format, the object
50 code would need to be patched with the offsets when producing .o files.
52 The basic technique taken in this implementation is to #include the code
53 from aoutx.h and aout-target.h with appropriate #defines to override
54 code where a unique implementation is needed:
57 #define a bunch of stuff
60 implement a bunch of functions
62 #include "aout-target.h"
65 The hp symbol table is a bit different than other a.out targets. Instead
66 of having an array of nlist items and an array of strings, hp's format
67 has them mixed together in one structure. In addition, the strings are
68 not null terminated. It looks something like this:
76 The whole symbol table is read as one chunk and then we march thru it
77 and convert it to canonical form. As we march thru the table, we copy
78 the nlist data into the internal form and we compact the strings and null
79 terminate them, using storage from the already allocated symbol table:
