we only generate dynamic R_ARM_RELATIVE relocations for R_ARM_ABS32
and R_ARM_ABS32_NOI. Generate R_ARM_IRELATIVE relocations instead
of R_ARM_RELATIVE relocations if the target is an STT_GNU_IFUNC
symbol. Pass the symbol type to arm_type_of_stub. Conditionally
resolve GOT references to the .igot.plt entry.
(elf32_arm_relocate_section): Update the call to
elf32_arm_final_link_relocate.
(elf32_arm_gc_sweep_hook): Use elf32_arm_get_plt_info to get PLT
information. Treat R_ARM_REL32 and R_ARM_REL32_NOI as call
relocations in shared libraries and relocatable executables.
Count non-call PLT references. Use elf32_arm_get_local_dynreloc_list
to get the list of dynamic relocations for a local symbol.
(elf32_arm_check_relocs): Always create ifunc sections. Set isym
at the same time as setting h. Use elf32_arm_allocate_local_sym_info
to allocate local symbol information. Treat R_ARM_REL32 and

relocatable executables. Record PLT information for local
STT_GNU_IFUNC functions as well as global functions. Count
non-call PLT references. Use elf32_arm_get_local_dynreloc_list
to get the list of dynamic relocations for a local symbol.
(elf32_arm_adjust_dynamic_symbol): Handle STT_GNU_IFUNC symbols.
Don't remove STT_GNU_IFUNC PLTs unless all references have been
removed. Update after the changes to elf32_arm_link_hash_entry.
(allocate_dynrelocs_for_symbol): Decide whether STT_GNU_IFUNC PLT
entries should live in .plt or .iplt. Check whether the .igot.plt
and .got entries can be combined. Use elf32_arm_allocate_plt_entry
to allocate .plt and .(i)got.plt entries. Detect which .got
entries will need R_ARM_IRELATIVE relocations and use
elf32_arm_allocate_irelocs to allocate them. Likewise other
non-.got dynamic relocations.
(elf32_arm_size_dynamic_sections): Allocate .iplt, .igot.plt
and dynamic relocations for local STT_GNU_IFUNC symbols.
Check whether the .igot.plt and .got entries can be combined.
Detect which .got entries will need R_ARM_IRELATIVE relocations
and use elf32_arm_allocate_irelocs to allocate them. Use stashed
section pointers intead of strcmp checks. Handle iplt and igotplt.
(elf32_arm_finish_dynamic_symbol): Use elf32_arm_populate_plt_entry
to fill in .plt, .got.plt and .rel(a).plt entries. Point
STT_GNU_IFUNC symbols at an .iplt entry if non-call relocations
resolve to it.
(elf32_arm_output_plt_map_1): New function, split out from
elf32_arm_output_plt_map. Handle .iplt entries. Use
