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
2003-06-25 06:40:27 +00:00
reloc addend when producing relocatable 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).
2003-06-25 06:40:27 +00:00
So everything works fine when not producing relocatable
output. When we are producing relocatable output, logically
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
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,
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. */

Fallout from recent bfd_reloc_outofrange changes Commit ec93045b and cd21f5da introduced a large number of tic4x and tic54x regressions, due to the new checks being wrong for targets with octets_per_byte != 1. To fix that I introduced a new bfd_get_section_limit_octets and performed the check on octets rather than byte adresses, reducing the number of bfd_octets_per_byte calls. bfd_octets_per_byte is rather expensive.. I then wondered why the same bfd_reloc_outofrange check added to bfd_perform_relocation wasn't also added to bfd_install_relocation. The two functions are virtually identical and ought to remain that way. However, adding the same check to bfd_install_relocation resulted in ld-elf "FAIL Link eh-group.o to eh-group" on many ELF targets, including x64_64-linux. The reason being that eh-group.o has NONE relocs at the end of a section, and most targets give NONE relocs a non-zero size. So if we are to keep the new outofrange check it appears that NONE relocs must have a zero size. * bfd-in.h (bfd_get_section_limit_octets): New define, extracted from..
