-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_install_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
-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).
-
-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 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).
-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_install_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. */
