 228         to get the list of dynamic relocations for a local symbol.
 229         (elf32_arm_check_relocs): Always create ifunc sections.  Set isym
 230         at the same time as setting h.  Use elf32_arm_allocate_local_sym_info
 231         to allocate local symbol information.  Treat R_ARM_REL32 and
 232         R_ARM_REL32_NOI as call relocations in shared libraries and
 233         relocatable executables.  Record PLT information for local
 234         STT_GNU_IFUNC functions as well as global functions.   Count
 235         non-call PLT references.  Use elf32_arm_get_local_dynreloc_list
 236         to get the list of dynamic relocations for a local symbol.

 238         Don't remove STT_GNU_IFUNC PLTs unless all references have been
 239         removed.  Update after the changes to elf32_arm_link_hash_entry.
 240         (allocate_dynrelocs_for_symbol): Decide whether STT_GNU_IFUNC PLT
 241         entries should live in .plt or .iplt.  Check whether the .igot.plt
 242         and .got entries can be combined.  Use elf32_arm_allocate_plt_entry
 243         to allocate .plt and .(i)got.plt entries.  Detect which .got
 244         entries will need R_ARM_IRELATIVE relocations and use
 245         elf32_arm_allocate_irelocs to allocate them.  Likewise other
 246         non-.got dynamic relocations.
 247         (elf32_arm_size_dynamic_sections): Allocate .iplt, .igot.plt
 248         and dynamic relocations for local STT_GNU_IFUNC symbols.

 250         Detect which .got entries will need R_ARM_IRELATIVE relocations
 251         and use elf32_arm_allocate_irelocs to allocate them.  Use stashed
 252         section pointers intead of strcmp checks.  Handle iplt and igotplt.

 254         to fill in .plt, .got.plt and .rel(a).plt entries.  Point
 255         STT_GNU_IFUNC symbols at an .iplt entry if non-call relocations
 256         resolve to it.
 257         (elf32_arm_output_plt_map_1): New function, split out from
 258         elf32_arm_output_plt_map.  Handle .iplt entries.  Use
 259         elf32_arm_plt_needs_thumb_stub_p.
