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.

i386-aout, pcrel_offset is false. Some other targets do not

|

|
|
However, Ian wrote the following, regarding removing the line below,
|
|
which explains why it is still enabled: --djm
|
|
|
|
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 reloc addend when producing
|
|
relocateable output for COFF. 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).
|
|
|
|
So everything works fine when not producing relocateable output. When
|
|
we are producing relocateable output, logically we should do exactly
|
|
what we do when not producing relocateable output. Therefore, your
|
|
patch is correct. In 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).
|
|
|
|
When I wanted to make coff-i386 produce relocateable output, 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
