 213         at the same time as setting h.  Use elf32_arm_allocate_local_sym_info
 214         to allocate local symbol information.  Treat R_ARM_REL32 and

 221         Don't remove STT_GNU_IFUNC PLTs unless all references have been
 222         removed.  Update after the changes to elf32_arm_link_hash_entry.
 223         (allocate_dynrelocs_for_symbol): Decide whether STT_GNU_IFUNC PLT
 224         entries should live in .plt or .iplt.  Check whether the .igot.plt
 225         and .got entries can be combined.  Use elf32_arm_allocate_plt_entry
 226         to allocate .plt and .(i)got.plt entries.  Detect which .got
 227         entries will need R_ARM_IRELATIVE relocations and use
 228         elf32_arm_allocate_irelocs to allocate them.  Likewise other
 229         non-.got dynamic relocations.

 238         STT_GNU_IFUNC symbols at an .iplt entry if non-call relocations
 239         resolve to it.
 240         (elf32_arm_output_plt_map_1): New function, split out from
 241         elf32_arm_output_plt_map.  Handle .iplt entries.  Use
