Regarding for the indirect symbol case you pointed out,
I saw the following code in elfNN_aarch64_check_relocs ()
if (r_symndx < symtab_hdr->sh_info)
/* A local symbol. */
h = sym_hashes[r_symndx - symtab_hdr->sh_info];
while (h->root.type == bfd_link_hash_indirect
|| h->root.type == bfd_link_hash_warning)
h = (struct elf_link_hash_entry *) h->root.u.i.link;
This is done before the check happens.
Does this mean, h is already been processed to points to final symbol?
Yes. :-) [I should have looked further back in the code when I was reviewing the patch].
Not at all! It is a good point. I didn't consider the case you mentioned when I wrote the patch.
It happens that it is properly handled.
