The behaviour seems to be different when RTLD_NOW is not specified,
at least on my 32-bit linux box.
That shouldn't be a lot of work. The same relocation is already
implemented for Darwin/x86_64. [...]
Can I interpret this as: "I am willing to implement this for
Linux/x86_64"? ;-) I am not sure if I found the correct place in
Linker.c
you've mentioned.
I guess I could find some time to play around with it on the weekend.
I don't have an x86_64-linux box available right now, but I might
either try some virtualisation software or just do a rough sketch and
leave you to do the debugging ;-).
R_X86_64_GOTPCREL for ELF is equivalent to X86_64_RELOC_GOT for Mach-
O. I would activate the "SymbolExtra" mechanism for x86_64-ELF; that
is a hack for putting extra per-symbol things right next to the .o
file image (and thus within range); SymbolExtras are already used on
powerpc-darwin, x86_64-darwin and powerpc-linux. I'll have a closer
look at what exactly needs to be done when I have time.
Cheers,
Wolfgang
