But we are sorting the table exactly as gas only for easier comparison of the generated o files, aren't we?

// There may be more ways to sort the table while respecting the ABI rule;
// we always sort the same way gnu as does, for compatibility.

Still not particularly clear. We *have* to sort it in a way that
causes bfd ld to match the same hi and lo relocations as would be
matched had the .s been assembled by gas.

Still not there. Which relocation gets matched to another is part of

of the semantics of the assembly file. We have to match gas or
document that we are incompatible.

Copied the sentence from the generic sortRelocs().

That is a very different case. That is about ELF, not mips-ELF.

On ELF, the order is not important, and we just need to make sure it
is deterministic. On mips-ELF it is part of the semantics of the .o.

But it cant introduce a wrong result if another relocation is 1 byte
away, no? We just know that that is not possible? If so please add a
comment about that.

Yes, Mips instructions length is fixed and at least 2 bytes (2 for micromips and mips16, 4 for mips32 and mips64), so there will always be 2 or 4 bytes offset between 2 instructions.
