I think it can be generic, like this:
/* Check for the end of the table: */
if (reloc != table && reloc == next_table)
break;
if (reloc != table &&
reloc_offset(reloc) == reloc_offset(table) +
rodata_table_size)
break;
What do you think?
I'm not sure, this patch is hard to review because it uses
insn->table_size which doesn't get set until the next patch.
Maybe this patch should come after patches 7 & 8, or maybe they should
be squashed?
OK, I will squash the changes into patch #7.
I remembered Ard already solved a similar problem when he prototyped x86
jump table annotation. Can you pull this patch into your series:
https://lore.kernel.org/20241011170847.334429-12-ardb+git@xxxxxxxxxx
Actually, I think I'm going to merge patches 2-5 from Ard's series as
they're a nice cleanup. Let me do that and then you can base your next
version off tip/objtool/core once it gets updated with Ard's and Peter's
patches.
Still talking to myself here, I think we'll only merge the above patch,
since we don't know what the generic annotations are going to look like
yet.
