After relocation, when error happends, it is hard to track ELR and LR with asm file objdumped from elf file.
So subtract the gd->reloc_off the reflect the compliation address.

It is useful to show the relocated address, the kind of local mods I too have had for a while. But here you dropped the hw register values altogether, instead of displaying both, which I guess I am not the only one to not be happy about.
Yes I agree that we should have both. Do you think you could do a patch?
Hi,
Peng did reply with a patch[1], I was bugged by the formatting but no follow-up ensued, so unclear whether it felt annoying on anybody's side. Anyways sure, if the thread stalls for a few more days, I'll make sure to send a patch.
