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.
