* bfd/bfd-in.h (bfd_elf32_arm_set_target_relocs): Update prototype.
* bfd/bfd-in2.h: Regenerate. * bfd/elf32-arm.c (elf32_arm_link_hash_table): New field, 'use_blx'. (elf32_arm_link_hash_table_create): Initialise fix_v4bx, use_blx. (bfd_elf32_arm_set_target_relocs): Handle use_blx. (elf32_arm_final_link_relocate): Use Thumb BLX for R_ARM_THM_PC22 relocations if requested to. (allocate_dynrelocs): Don't count size of omitted Thumb stubs based on use_blx rather than symbian_p. (elf32_arm_finish_dynamic_symbol): Don't output Thumb PLT stubs if use_blx is in effect. (elf32_arm_symbian_link_hash_table_create): Enable use_blx by default for SymbianOS. * ld/ld.texinfo: Document --use-blx. * ld/emultempl/armelf.em (use_blx): New variable. (arm_elf_create_output_section_statements): Communicate value of use_blx to bfd. (PARSE_AND_LIST_PROLOGUE): Add OPTION_USE_BLX. (PARSE_AND_LIST_OPTIONS): Add --use-blx option. (PARSE_AND_LIST_ARGS_CASES): Add OPTION_USE_BLX case.
