215 We start by subtracting the address of the section containing
216 the location.
218 If pcrel_offset is set, we must further subtract the position
219 of the location within the section. Some targets arrange for
220 the addend to be the negative of the position of the location
221 within the section; for example, i386-aout does this. For

273 However, Ian wrote the following, regarding removing the line
274 below, which explains why it is still enabled: --djm
276 If you put a patch like that into BFD you need to check all
277 the COFF linkers. I am fairly certain that patch will break
278 coff-i386 (e.g., SCO); see coff_i386_reloc in coff-i386.c
279 where I worked around the problem in a different way. There
280 may very well be a reason that the code works as it does.
282 Hmmm. The first obvious point is that bfd_perform_relocation
283 should not have any tests that depend upon the flavour. It's
284 seem like entirely the wrong place for such a thing. The
285 second obvious point is that the current code ignores the
286 reloc addend when producing relocatable output for COFF.
287 That's peculiar. In fact, I really have no idea what the
288 point of the line you want to remove is.
290 A typical COFF reloc subtracts the old value of the symbol
291 and adds in the new value to the location in the object file
292 (if it's a pc relative reloc it adds the difference between
293 the symbol value and the location). When relocating we need
294 to preserve that property.
296 BFD handles this by setting the addend to the negative of the
297 old value of the symbol. Unfortunately it handles common
298 symbols in a non-standard way (it doesn't subtract the old
299 value) but that's a different story (we can't change it
300 without losing backward compatibility with old object files)
301 (coff-i386 does subtract the old value, to be compatible with
302 existing coff-i386 targets, like SCO).
304 So everything works fine when not producing relocatable
305 output. When we are producing relocatable output, logically
306 we should do exactly what we do when not producing
307 relocatable output. Therefore, your patch is correct. In
308 fact, it should probably always just set reloc_entry->addend
309 to 0 for all cases, since it is, in fact, going to add the
310 value into the object file. This won't hurt the COFF code,
311 which doesn't use the addend; I'm not sure what it will do
312 to other formats (the thing to check for would be whether
313 any formats both use the addend and set partial_inplace).
315 When I wanted to make coff-i386 produce relocatable output,
316 I ran into the problem that you are running into: I wanted
317 to remove that line. Rather than risk it, I made the
318 coff-i386 relocs use a special function; it's coff_i386_reloc
319 in coff-i386.c. The function specifically adds the addend
320 field into the object file, knowing that bfd_perform_relocation
321 is not going to. If you remove that line, then coff-i386.c
322 will wind up adding the addend field in twice. It's trivial
323 to fix; it just needs to be done.
325 The problem with removing the line is just that it may break
326 some working code. With BFD it's hard to be sure of anything.
327 The right way to deal with this is simply to build and test at
328 least all the supported COFF targets. It should be
329 straightforward if time and disk space consuming. For each
330 target:
331 1) build the linker
332 2) generate some executable, and link it using -r (I would
333 probably use paranoia.o and link against newlib/libc.a,
334 which for all the supported targets would be available in
335 /usr/cygnus/progressive/H-host/target/lib/libc.a).
336 3) make the change to reloc.c
337 4) rebuild the linker
338 5) repeat step 2
339 6) if the resulting object files are the same, you have at
340 least made it no worse
341 7) if they are different you have to figure out which
342 version is right. */
