elf32_arm_create_dynamic_sections was used to set plt_header_size and plt_entry_size. This necessitated a hack for using_thumb_only() as the output file attributes used by that function are not set until lang_check calls bfd_merge_private_bfd_data. Now the earliest use of plt_header_size and plt_entry_size is in elf32_arm_late_size_sections, called from bfd_elf_size_dynamic_sections. So this patch moves the initialisation of these variables to elf32_arm_late_size_sections. Initialising them there is after lang_check runs, and also guarantees they are initialised for all later uses too. The patch also moves initialisation of htab->stub_bfd earlier, and calls to add_glue_sections_to_bfd and get_bfd_for_interworking from ld/armelf.em to bfd/elf32-arm.c. I removed an abort in elf32_arm_create_dynamic_sections too. It really doesn't improve confidence that much to check that a function you have just called to create dynamic sections has done its job. PR 16017 bfd/ * elf32-arm.c (elf32_arm_plt_needs_thumb_stub_p): Formatting. (elf32_arm_create_dynamic_sections): Remove abort. Move initialisation of plt_header_size and plt_entry_size to.. (elf32_arm_late_size_sections): ..here. (bfd_elf32_arm_add_glue_sections_to_bfd), (bfd_elf32_arm_get_bfd_for_interworking): Make static. (bfd_elf32_arm_set_target_params): Add stub_bfd param. Remove output_bfd param. Make params const. Init globals->stub_bfd. Set flags and EI_CLASS for stub_bfd. Call add_glue_sections_to_bfd and get_bfd_for_interworking. * elf32-arm.h (bfd_elf32_arm_add_glue_sections_to_bfd), (bfd_elf32_arm_get_bfd_for_interworking): Delete declarations.

Pass stub bfd to set_target_params.
