> 	* elf32-arm.h (ARM_PLT_ENTRY_SIZE): Rename PLT_ENTRY_SIZE.
> 	(THUMB_PLT_ENTRY_SIZE): New macro.
> 	(PLT_ENTRY_SIZE): Return the appropriate *_PLT_ENTRY_SIZE.
> 	(elf32_arm_plt0_entry): Rename PLT_ENTRY_SIZE to
> 	(elf32_arm_plt_entry): Likewise.
> 	(elf_backend_plt_header_size): Likewise.
> 	(elf32_thumb_plt0_entry): New global.
> 	(elf32_arm_finish_dynamic_sections): Use it.  Put Thumb entries
> 	into .plt.thumb.
> 	(elf32_thumb_plt_entry): New global.
> 	(elf32_arm_finish_dynamic_symbol): Use it.  Use .thumb.plt for
> 	Thumb entries.  Set the bottom bit of the corresponding GOT entry
> 	for a Thumb PLT entry.
> 	(struct elf32_arm_plt_entry_info): New structure.
> 	(struct elf32_arm_link_hash_entry, plt_info): New member of this

> 	(elf32_arm_check_relocs, case R_ARM_THM_PC22 case): New case.
> 	Determine if relocation needs a PLT entry.  Set first_rel_type if

> 	(elf32_arm_adjust_dynamic_symbol): Create PLT entries for Thumb
> 	functions as well.
> 	(elf32_arm_size_dynamic_sections): Handle .plt.thumb like .plt.
> 	(elf32_arm_create_dynamic_sections): New function.  Create the
