* section.c (struct sec): Rename "_cooked_size" to "size". Rename "_raw_size" to "rawsize". (STD_SECTION): Adjust comments. (bfd_set_section_size, bfd_get_section_contents): Use size. (bfd_malloc_and_get_section): New function. * bfd-in.h (bfd_section_size, bfd_get_section_size): Use size. * coff-sh.c (sh_relax_section): Alloc coff_section_data struct early. Correctly free reloc and contents memory. * elf-eh-frame.c (_bfd_elf_discard_section_eh_frame): Delete FIXME and fake CIE now that we can shink section size to zero. (_bfd_elf_write_section_eh_frame): Likewise.. * elf32-ppc.c (ppc_elf_relax_section): Delay reading section contents. * elf-m10300.c (mn10300_elf_final_link_relocate): Don't use _bfd_stab_section_offset. Use _bfd_elf_section_offset. * stabs.c (_bfd_stab_section_offset_): Remove unused args and unneeded indirection. * elf.c (_bfd_elf_section_offset): .. and update call. * libbfd-in.h (_bfd_stab_section_offset): Update prototype. * libbfd.h: Regenerate. * bfd-in2.h: Regenerate. Replace occurrences of "_raw_size" and "_cooked_size" in most places with "size". Set new "rawsize" for stabs, eh_frame, and SEC_MERGE sections. Use "rawsize", if non-zero, for bfd_get_section_contents calls if the section might be a stabs, eh_frame, or SEC_MERGE section. Similarly use "rawsize", if non-zero, in reloc functions to validate reloc addresses. Use new bfd_malloc_and_get_section in most places where bfd_get_section_contents was called. Expand all occurrences of bfd_section_size and bfd_get_section_size. Rename "raw_size" var in grok_prstatus and similar functions to "size". * aix386-core.c (aix386_core_file_p): .. * aix5ppc-core.c (xcoff64_core_p): .. * aout-adobe.c (aout_adobe_callback,

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.
|
|
|
|
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] */
