  95         at the same time as setting h.  Use elf32_arm_allocate_local_sym_info
  96         to allocate local symbol information.  Treat R_ARM_REL32 and
  97         R_ARM_REL32_NOI as call relocations in shared libraries and
  98         relocatable executables.  Record PLT information for local
  99         STT_GNU_IFUNC functions as well as global functions.   Count
 100         non-call PLT references.  Use elf32_arm_get_local_dynreloc_list

 105         (allocate_dynrelocs_for_symbol): Decide whether STT_GNU_IFUNC PLT
 106         entries should live in .plt or .iplt.  Check whether the .igot.plt
 107         and .got entries can be combined.  Use elf32_arm_allocate_plt_entry
 108         to allocate .plt and .(i)got.plt entries.  Detect which .got
 109         entries will need R_ARM_IRELATIVE relocations and use
 110         elf32_arm_allocate_irelocs to allocate them.  Likewise other

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