* arm.cc (Target_arm::can_check_for_functions_pointers): Return true. (Target_arm::section_may_have_icf_unsafe_pointers): New method definition. (Target_arm::Scan::local_reloc_may_be_function_pointer, Target_arm::Scan::global_reloc_may_be_function_pointer): Implement target hook to detect function points. (Target_arm::Scan::possible_function_pointer_reloc): New method. * icf.h (Icf::check_section_for_function_pointers): Change type of parameter SECTION_NAME to const reference to std::string. Use target hook to determine if section may have unsafe pointers. * target.h (Target::section_may_have_icf_unsafe_pointers): New method definition.
