[Morello] Insufficient R_MORELLO_JUMP_SLOT documentation #69

[amilendra]

Fix the specification for R_MORELLO_JUMP_SLOT to use the same format as R_MORELLO_RELATIVE.

If you haven't got the necessary permission, now that this has been approved, let me know if you'd like me to merge this PR?

[amilendra]

Yes please merge it for me. I don't seem to have the necessary permissions.

Hm, while this is the right thing for the ABI to do, it's not what Morello LLVM has implemented to date. There is https://git.morello-project.org/morello/llvm-project/-/merge_requests/296 to switch to this, but that's been stalled for just under a year. If that MR is going to be revived soon then I guess things are ok, but otherwise I'm not sure about the wisdom of merging ABI documentation that differs from what Morello LLVM implements (and presumably Morello binutils too, though that's not relevant to CheriBSD)?

@amilendra what do you want to do about https://git.morello-project.org/morello/llvm-project/-/merge_requests/296 is this something that you can pursue or hand over to someone that can?

[amilendra]

I put it down last year with the expectation that Linaro would take over. If there is permission from management I can restart work on it. I think @simonwallis2 will get back to me regarding that.
