/* BFD support for the ns32k architecture.

bfd/
* 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".

o bfd_read and bfd_write lose an unnecessary param and become

o bfd_*alloc now all take a bfd_size_type arg, and will error if
size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files
or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and

If you put a patch like that into BFD you need to check all
|
|
|
|
the COFF linkers. I am fairly certain that patch will break
|
|
|
|
coff-i386 (e.g., SCO); see coff_i386_reloc in coff-i386.c
|
|
|
|
where I worked around the problem in a different way. There
|
|
|
|
may very well be a reason that the code works as it does.
|
|
|
|
|
|
|
|
Hmmm. The first obvious point is that bfd_perform_relocation
|
|
|
|
should not have any tests that depend upon the flavour. It's
|
|
|
|
seem like entirely the wrong place for such a thing. The
|
|
|
|
second obvious point is that the current code ignores the
|
2003-06-25 06:40:27 +00:00
|
|
|
reloc addend when producing relocatable output for COFF.
|
2002-07-31 16:23:29 +00:00
|
|
|
That's peculiar. In fact, I really have no idea what the
|
|
|
|
point of the line you want to remove is.
|
|
|
|
|
|
|
|
A typical COFF reloc subtracts the old value of the symbol
|
|
|
|
and adds in the new value to the location in the object file
|
|
|
|
(if it's a pc relative reloc it adds the difference between
|
|
|
|
the symbol value and the location). When relocating we need
|
|
|
|
to preserve that property.
|
|
|
|
|
|
|
|
BFD handles this by setting the addend to the negative of the
|
|
|
|
old value of the symbol. Unfortunately it handles common
|
|
|
|
symbols in a non-standard way (it doesn't subtract the old
|
|
|
|
value) but that's a different story (we can't change it
|
|
|
|
without losing backward compatibility with old object files)
|
|
|
|
(coff-i386 does subtract the old value, to be compatible with
|
|
|
|
existing coff-i386 targets, like SCO).
|
|
|
|
|
2003-06-25 06:40:27 +00:00
|
|
|
So everything works fine when not producing relocatable
|
|
|
|
output. When we are producing relocatable output, logically
|
2002-07-31 16:23:29 +00:00
|
|
|
we should do exactly what we do when not producing
|
2003-06-25 06:40:27 +00:00
|
|
|
relocatable output. Therefore, your patch is correct. In
|
2002-07-31 16:23:29 +00:00
|
|
|
fact, it should probably always just set reloc_entry->addend
|
|
|
|
to 0 for all cases, since it is, in fact, going to add the
|
|
|
|
value into the object file. This won't hurt the COFF code,
|
|
|
|
which doesn't use the addend; I'm not sure what it will do
|
|
|
|
to other formats (the thing to check for would be whether
|
|
|
|
any formats both use the addend and set partial_inplace).
|
|
|
|
|
2003-06-25 06:40:27 +00:00
|
|
|
When I wanted to make coff-i386 produce relocatable output,
|
2002-07-31 16:23:29 +00:00
|
|
|
I ran into the problem that you are running into: I wanted
|
|
|
|
to remove that line. Rather than risk it, I made the
|
|
|
|
coff-i386 relocs use a special function; it's coff_i386_reloc
|
|
|
|
in coff-i386.c. The function specifically adds the addend
|
|
|
|
field into the object file, knowing that bfd_perform_relocation
|
|
|
|
is not going to. If you remove that line, then coff-i386.c
|
|
|
|
will wind up adding the addend field in twice. It's trivial
|
|
|
|
to fix; it just needs to be done.
|
|
|
|
|
|
|
|
The problem with removing the line is just that it may break
|
|
|
|
some working code. With BFD it's hard to be sure of anything.
|
|
|
|
The right way to deal with this is simply to build and test at
|
|
|
|
least all the supported COFF targets. It should be
|
|
|
|
straightforward if time and disk space consuming. For each
|
|
|
|
target:
|
|
|
|
1) build the linker
|
|
|
|
2) generate some executable, and link it using -r (I would
|
|
|
|
probably use paranoia.o and link against newlib/libc.a,
|
|
|
|
which for all the supported targets would be available in
|
|
|
|
/usr/cygnus/progressive/H-host/target/lib/libc.a).
|
|
|
|
3) make the change to reloc.c
|
|
|
|
4) rebuild the linker
|
|
|
|
5) repeat step 2
|
|
|
|
6) if the resulting object files are the same, you have at
|
|
|
|
least made it no worse
|
|
|
|
7) if they are different you have to figure out which
|
|
|
|
version is right. */

Touches most files in bfd/, so likely will be blamed for everything..
o bfd_read and bfd_write lose an unnecessary param and become
bfd_bread and bfd_bwrite.
o bfd_*alloc now all take a bfd_size_type arg, and will error if
size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files
or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and
bfd_byte * as appropriate, which removes a swag of casts from the
source.
o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
aout-encap.c.
o Zillions of formatting and -Wconversion fixes.
