 108         at the same time as setting h.  Use elf32_arm_allocate_local_sym_info
 109         to allocate local symbol information.  Treat R_ARM_REL32 and
 110         R_ARM_REL32_NOI as call relocations in shared libraries and
 111         relocatable executables.  Record PLT information for local
 112         STT_GNU_IFUNC functions as well as global functions.   Count
 113         non-call PLT references.  Use elf32_arm_get_local_dynreloc_list

 118         (allocate_dynrelocs_for_symbol): Decide whether STT_GNU_IFUNC PLT
 119         entries should live in .plt or .iplt.  Check whether the .igot.plt
 120         and .got entries can be combined.  Use elf32_arm_allocate_plt_entry
 121         to allocate .plt and .(i)got.plt entries.  Detect which .got
 122         entries will need R_ARM_IRELATIVE relocations and use
 123         elf32_arm_allocate_irelocs to allocate them.  Likewise other
 124         non-.got dynamic relocations.

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