* elf32-arm.c (INTERWORK_FLAG): Check BFD_LINKER_CREATED. (elf32_arm_write_section): Declare early. (elf32_arm_size_stubs): Skip non-stub sections in the stub BFD. (arm_allocate_glue_section_space): Exclude empty sections. (ARM_GLUE_SECTION_FLAGS): Add SEC_LINKER_CREATED. (bfd_elf32_arm_add_glue_sections_to_bfd): Do not skip the stub BFD. (elf32_arm_output_glue_section, elf32_arm_final_link): New. (elf32_arm_merge_eabi_attributes): Skip the stub BFD. (elf32_arm_size_dynamic_sections): Allocate interworking sections here. (bfd_elf32_bfd_final_link): Define. ld/ * emultempl/armelf.em (bfd_for_interwork, arm_elf_after_open) (arm_elf_set_bfd_for_interworking): Delete. (arm_elf_before_allocation): Do not set the interworking BFD. Move allocation inside not-dynamic block. (arm_elf_create_output_section_statements): Create glue sections and set the interworking BFD here. (LDEMUL_AFTER_OPEN): Delete. ld/testsuite/ * ld-arm/farcall-mix.d, ld-arm/farcall-mix2.d, ld-arm/farcall-group-size2.d, ld-arm/farcall-group.d, ld-arm/farcall-mixed-lib.d: Update for linker changes.
