elfcpp/ChangeLog * arm.h: New enums for EABI object attribute tags and values. gold/ChangeLog * arm.cc (attributes.h): New include. (Arm_relobj::Arm_relobj): Initialize attributes_section_data_. (Arm_relobj::~Arm_relobj): Delete object pointed by attributes_section_data_. (Arm_relobj::attributes_section_data): New method definition. (Arm_relobj::attributes_section_data_): New data member declaration. (Arm_dynobj::Arm_dynobj): Initialize attributes_section_data_. (Arm_dynobj::~Arm_dynobj): Delete object pointed by attributes_section_data_. (Arm_dynobj::attributes_section_data): New method definition. (Arm_dynobj::attributes_section_data_): New data member declaration. (Target_arm::Target_arm): Initialize attributes_section_data_. Change initialization value of may_use_blx_ to false. (Target_arm::using_thumb2, Target_arm::using_thumb_only, Target_arm::may_use_arm_nop, Target_arm::may_use_thumb2_nop): Use object attributes to compute results instead of hard-coding. (Target_arm::do_attribute_arg_type, Target_arm::do_attributes_order, Target_arm::get_secondary_compatible_arch, Target_arm::set_secondary_compatible_arch Target_arm::tag_cpu_arch_combine, Target_arm::aeabi_enum_name, Target_arm::tag_cpu_name_value, Target_arm::merge_object_attributes): New method declarations. (Target_arm::get_aeabi_object_attribute): New method definition. (Target_arm::attributes_section_data_): New data member declaration. (read_arm_attributes_section): New template definition. (Arm_relobj::do_read_symbols): Read attributes section if it exists. (Arm_dynobj::do_read_symbols): Ditto. (Target_arm::do_finalize_sections): Merge attributes sections from input. Check for BLX use after attributes section merging. Fix __exidx_start and __exidx_end visibility. Create an .ARM.attributes section if necessary. (Target_arm::get_secondary_compatible_arch, Target_arm::set_secondary_compatible_arch, Target_arm::tag_cpu_arch_combine, Target_arm::aeabi_enum_name, Target_arm::tag_cpu_name_value, Target_arm::merge_object_attributes, Target_arm::do_attribute_arg_type, Target_arm::do_attributes_order): New method definitions.
