 160         .iplts.  Don't set sreloc for static relocations.  Assert that
 161         we only generate dynamic R_ARM_RELATIVE relocations for R_ARM_ABS32
 162         and R_ARM_ABS32_NOI.  Generate R_ARM_IRELATIVE relocations instead

 174         at the same time as setting h.  Use elf32_arm_allocate_local_sym_info
 175         to allocate local symbol information.  Treat R_ARM_REL32 and
 176         R_ARM_REL32_NOI as call relocations in shared libraries and
 177         relocatable executables.  Record PLT information for local
 178         STT_GNU_IFUNC functions as well as global functions.   Count
 179         non-call PLT references.  Use elf32_arm_get_local_dynreloc_list
 180         to get the list of dynamic relocations for a local symbol.

 182         Don't remove STT_GNU_IFUNC PLTs unless all references have been
 183         removed.  Update after the changes to elf32_arm_link_hash_entry.
 184         (allocate_dynrelocs_for_symbol): Decide whether STT_GNU_IFUNC PLT
 185         entries should live in .plt or .iplt.  Check whether the .igot.plt
 186         and .got entries can be combined.  Use elf32_arm_allocate_plt_entry
 187         to allocate .plt and .(i)got.plt entries.  Detect which .got
 188         entries will need R_ARM_IRELATIVE relocations and use
 189         elf32_arm_allocate_irelocs to allocate them.  Likewise other
 190         non-.got dynamic relocations.
 191         (elf32_arm_size_dynamic_sections): Allocate .iplt, .igot.plt

 198         to fill in .plt, .got.plt and .rel(a).plt entries.  Point
 199         STT_GNU_IFUNC symbols at an .iplt entry if non-call relocations
 200         resolve to it.
 201         (elf32_arm_output_plt_map_1): New function, split out from
 202         elf32_arm_output_plt_map.  Handle .iplt entries.  Use
