Has someone written an SYSVABI architecture specification for
your architecture?
I feel uncomfortable with the linux-kernel headers being the
authoritative place for the ELF abi definitions.
Especially since the linux kernel does not deal with relocations,
and the kernel headers could diverge from the real world and no one
would notice..
I know at least at one point the linux standards base was taking
up the work on collecting up some of these definitions. I would
be happy if there was anything outside of the linux kernel that
people could refer too.
