* bfd-in2.h: Regenerate.
* elf32-arm.c (elf32_arm_howto_table_2): Rename existing definition
to elf32_arm_howto_table_3 and replace with a single R_ARM_IRELATIVE
entry.
(elf32_arm_howto_from_type): Update accordingly.
(elf32_arm_reloc_map): Map BFD_RELOC_ARM_IRELATIVE to R_ARM_IRELATIVE.
(elf32_arm_reloc_name_lookup): Handle elf32_arm_howto_table_3.
(arm_plt_info): New structure, split out from elf32_arm_link_hash_entry
with an extra noncall_refcount field.
(arm_local_iplt_info): New structure.
(elf_arm_obj_tdata): Add local_iplt.
(elf32_arm_local_iplt): New accessor macro.
(elf32_arm_link_hash_entry): Replace plt_thumb_refcount,
plt_maybe_thumb_refcount and plt_got_offset with an arm_plt_info.
Change tls_type to a bitfield and add is_iplt.
(elf32_arm_link_hash_newfunc): Update accordingly.
(elf32_arm_allocate_local_sym_info): New function.
(elf32_arm_create_local_iplt): Likewise.
(elf32_arm_get_plt_info): Likewise.
(elf32_arm_plt_needs_thumb_stub_p): Likewise.
(elf32_arm_get_local_dynreloc_list): Likewise.
(create_ifunc_sections): Likewise.
(elf32_arm_copy_indirect_symbol): Update after the changes to
elf32_arm_link_hash_entry. Assert the is_iplt has not yet been set.
(arm_type_of_stub): Add an st_type argument. Use elf32_arm_get_plt_info
to get PLT information. Assert that all STT_GNU_IFUNC references
are turned into PLT references.
(arm_build_one_stub): Pass the symbol type to
elf32_arm_final_link_relocate.
(elf32_arm_size_stubs): Pass the symbol type to arm_type_of_stub.
(elf32_arm_allocate_irelocs): New function.
(elf32_arm_add_dynreloc): In static objects, use .rel.iplt for
all R_ARM_IRELATIVE.
(elf32_arm_allocate_plt_entry): New function.
(elf32_arm_populate_plt_entry): Likewise.
(elf32_arm_final_link_relocate): Add an st_type parameter.
Set srelgot to null for static objects. Use separate variables
to record which st_value and st_type should be used when generating
a dynamic relocation. Use elf32_arm_get_plt_info to find the
symbol's PLT information, setting has_iplt_entry, splt,
plt_offset and gotplt_offset accordingly. Check whether
STT_GNU_IFUNC symbols should resolve to an .iplt entry, and change
the relocation target accordingly. Broaden assert to include
.iplts. Don't set sreloc for static relocations. Assert that
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
R_ARM_REL32_NOI as call relocations in shared libraries 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
elf32_arm_plt_needs_thumb_stub_p.
(elf32_arm_output_plt_map): Call it.
(elf32_arm_output_arch_local_syms): Add mapping symbols for
local .iplt entries.
(elf32_arm_swap_symbol_in): Handle Thumb STT_GNU_IFUNC symbols.
(elf32_arm_swap_symbol_out): Likewise.
(elf32_arm_add_symbol_hook): New function.
(elf_backend_add_symbol_hook): Define for all targets.
opcodes/
* arm-dis.c (get_sym_code_type): Treat STT_GNU_IFUNCs as code.
gas/
* config/tc-arm.c (md_pcrel_from_section): Use S_FORCE_RELOC to
determine whether a relocation is needed.
(md_apply_fix, arm_apply_sym_value): Likewise.
