* arm.cc (Target_arm::Target_arm): Move method definition outside of
class definition. Add code to handle --target1-rel, --target1-abs
and --target2= options.
(Target_arm::get_reloc_reloc_type): Change method to be non-static
and const.
(Target_arm::target1_is_rel_, Target_arm::target2_reloc_): New data
member declaration.
(Target_arm::Scan::local, Target_arm::Scan::global,
Target_arm::Relocate::relocate,
Target_arm::Relocatable_size_for_reloc::get_size_for_reloc): Adjust
call to Target_arm::get_real_reloc_type.
(Target_arm::get_real_reloc_type): Use command line options to
determine real types of R_ARM_TARGET1 and R_ARM_TARGET2.
* options.h (--target1-rel, --target1-abs, --target2): New ARM-only
options.
2016-08-31 Alan Modra <amodra@gmail.com>
* powerpc.cc (class Stub_control): Delete stub14_group_size_
