Strang code in elf_merge_symbol

[H . J . Lu]

In elf_merge_symbol, there is

  if (! newdyn
      && (newdef 
          || (bfd_is_com_section (sec)
              && (h->root.type == bfd_link_hash_defweak
                  || h->type == STT_FUNC)))
      && olddyn
      && olddef
      && (h->elf_link_hash_flags & ELF_LINK_HASH_DEF_DYNAMIC) != 0
      && (bind != STB_WEAK
          || h->root.type == bfd_link_hash_defweak))
    {

I don't understand

             (bfd_is_com_section (sec)
              && (h->root.type == bfd_link_hash_defweak
                  || h->type == STT_FUNC))

If the symbol is in the common section, can it be STT_FUNC?
