  70         to get the list of dynamic relocations for a local symbol.
  71         (elf32_arm_check_relocs): Always create ifunc sections.  Set isym
  72         at the same time as setting h.  Use elf32_arm_allocate_local_sym_info
  73         to allocate local symbol information.  Treat R_ARM_REL32 and
  74         R_ARM_REL32_NOI as call relocations in shared libraries and

  81         removed.  Update after the changes to elf32_arm_link_hash_entry.
  82         (allocate_dynrelocs_for_symbol): Decide whether STT_GNU_IFUNC PLT
  83         entries should live in .plt or .iplt.  Check whether the .igot.plt
  84         and .got entries can be combined.  Use elf32_arm_allocate_plt_entry
  85         to allocate .plt and .(i)got.plt entries.  Detect which .got
  86         entries will need R_ARM_IRELATIVE relocations and use
  87         elf32_arm_allocate_irelocs to allocate them.  Likewise other
  88         non-.got dynamic relocations.

  97         STT_GNU_IFUNC symbols at an .iplt entry if non-call relocations
  98         resolve to it.
  99         (elf32_arm_output_plt_map_1): New function, split out from
