[lld][ELF] Addends adjustment for relocatable object
...y we setup it using
constant offset from the .got section. Also it might be defined by a
linker script. And in rare but possible case it comes from .reginfo /
.MIPS.options sections.
Got example, GNU bfd linker has the following code to adjust
_gp-relative relocation addends:
rel->r_addend += _bfd_get_gp_value (input_bfd);
rel->r_addend -= _bfd_get_gp_value (output_bfd);
But I think we can escape to implement the same adjustments in LLD if
we do not support non-zero gp-value in the .reginfo / .MIPS.options
sections in input object files. We can get such files if somebody
produce a relocatable object...

[lld][ELF] Addends adjustment for relocatable object
You are right. LLD does not have this problem. Initially I bumped into
the MIPS specific bug related to GP relative relocations calculation.
I tried to make reproduction script as general as possible and
mistakenly make it too general. So now with your help I realized that
the problem solely affects MIPS.
