I have been studying ld.so and also Xorg as that has a loader function.
Its not clear to me that they handle just the same set of relocs.
The R_IA64_ defines in elf.h have two bit fields for the ia64 and
these are used in ld.so but that info seems not to be used in Xorg.
And bfd uses an enum so such structuring of the values isn't
possible.
I notice some comments about a standalone version of the loader
code. That should be very helpful if it works.
You said something about the heap having to do with the dlopen version
not working but I noticed some things that made me think that
dynamic linking, ie letting the lisp code access vars by name
was an issue. Can you provide more detail?
Any suggestions would be helpful.
