thus isolating the "iffy hueristic" from the rest of the relocation code.
* In the "iffy hueristic", use _GOT_END_, not _DYNAMIC.
* Include the addend in Alpha R(RELATIVE) relocations.
old PLT format, and one that works with the new.
XXX We currently always use _rtld_bind_start_old() in
_rtld_setup_alpha_pltgot(). We need to add code to peek
into one of the PLT entries to see which format it's in
and pick the correct binding routine.
relocs for local symbols as section-relative REL32 relocs with values based
at 0, whereas previously BFD generated those relocs with values based at the
start address of the section.
This code adjusts all STT_SECTION REL32 relocs which have values less than
the start of the section by adding in the base address of the section. This
may limit section sizes to 2GB, but that shouldn't be a problem for now.
XXX: Needs to be followed-up with binutils list to get closure on which
interpretation is correct (the new ABI or the old one), I just haven't
yet had the time to chase that.
was ambiguous in the case of a weak symbol that was not defined. This caused
RTLD_NOW to fail badly with shared libraries linked against the new crtbegin.o.
* Apply DT_PLTRELSZ to (one of) pltrel or pltrela *after* we've finished
parsing the headers, so we know which one.
* Fix sparc64 bogons. (It works now!)
testing and archival for now. I don't expect anyone to work with it
since the binutils and gas changes are still pending. But you got to
crawl before you walk.
try to check _rtld_objself when doing R_TYPE(RELATIVE) relocs, as the
Alpha ld.elf_so contains them!
I'm not sure the logic for the RELATIVE fix is quite right; it happens to
Work on alpha, but do we actually need to make sure we aren't relocating
ld.elf_so there?
XXX: I am working on making use of RTLD_RELOCATE_SELF on alpha, which may
make this hack of a fix moot.
I've not followed the trend in this file by trying to wrench the MD
code into individual functions. Rather I,ve replaced several functions
wholesale. Anyway, this whole file needs to be re-done.
not pointing to the PLT in _rtld_relocate_plt_object(). I'm not quite
sure why the i386 added the extra relocations, but it removed the `return
0' needed for other arches.
THIS DOES NOT YET FIX BUILDING LD.ELF_SO ON ALPHA. There are some other
binutils 2.9.1 related issues, but this does return build ability to
2.8.1 based as and ld. Will do more investigation later.
