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

 206         (allocate_dynrelocs_for_symbol): Decide whether STT_GNU_IFUNC PLT
 207         entries should live in .plt or .iplt.  Check whether the .igot.plt

 209         to allocate .plt and .(i)got.plt entries.  Detect which .got
 210         entries will need R_ARM_IRELATIVE relocations and use
 211         elf32_arm_allocate_irelocs to allocate them.  Likewise other
 212         non-.got dynamic relocations.

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