* arm.cc (Arm_exidx_cantunwind::do_print_to_mapfile): New method. (Arm_relobj::do_relocate_sections): Add new parameter for output file to match the parent. (Target_arm::scan_reloc_section_for_stubs): Use would-be final values of local symbols instead of input values. Update code to track changes in gold::relocate_section. * object.cc (Sized_relobj::compute_final_local_value): New methods. (Sized_relobj::compute_final_local_value_internal): New methods. (Sized_relobj::do_finalize_local_symbols): Move code from loop body into private version of Sized_relobj::compute_final_local_value. Call the inline method. * object.h (Symbol_value::Symbol_value): Define destructor. Free merged symbol value if there is one. (Symbol_value::has_output_value): New method defintiion. (Sized_relobj::Compute_final_local_value_status): New enum type. (Sized_relobj::compute_final_local_value): New methods. (Sized_relobj::compute_final_local_value_internal): New methods. * Makefile.am (check_SCRIPTS): Add arm_branch_out_of_range.sh and arm_cortex_a8.sh. (thumb_bl_out_of_range_local, arm_cortex_a8_b_cond, arm_cortex_a8_bl, arm_cortex_a8_blx, arm_cortex_a8_local, arm_corte_a8_local_reloc): New tests. * Makefile.in: Regenerate. * testsuite/arm_bl_out_of_range.s: Update test. * testsuite/thumb_bl_out_of_range.s: Ditto. * testsuite/thumb_blx_out_of_range.s: Ditto. * testsuite/arm_branch_out_of_range.sh: New file. * testsuite/arm_cortex_a8.sh: Ditto. * testsuite/arm_cortex_a8_b.s: Ditto. * testsuite/arm_cortex_a8_b_cond.s: Ditto. * testsuite/arm_cortex_a8_b_local.s: Ditto. * testsuite/arm_cortex_a8_bl.s: Ditto. * testsuite/arm_cortex_a8_blx.s: Ditto. * testsuite/arm_cortex_a8_local.s: Ditto. * testsuite/arm_cortex_a8_local_reloc.s: Ditto. * testsuite/thumb_bl_out_of_range_local.s: Ditto.
