* arm.cc (Arm_input_section::Arm_input_section): For a SHT_ARM_EXIDX section, always keeps the input sections. (Arm_input_section::set_exidx_section_link): New method. (Arm_exidx_input_section::Arm_exidx_input_section): Initialize has_errors_ to false. (Arm_exidx_input_section::has_errors, Arm_exidx_input_section::set_has_errors): New methods. (Arm_exidx_input_section::has_errors_): New data member. (Arm_relobj::get_exidx_shndx_list): New method. (Arm_output_section::append_text_sections_to_list): Do not skip section without SHF_EXECINSTR. (Arm_output_section::fix_exidx_coverage): Skip input sections with errors. (Arm_relobj::make_exidx_input_section): Add new parameter for text section header. Make error messages more verbose. Check for a non-executable section linked to an EXIDX section. (Arm_relobj::do_read_symbols): Remove error checking, which has been moved to Arm_relobj::make_exidx_input_section. Add an assertion to check that there is no deferred EXIDX section if we exit early. Instead of not making an EXIDX section in case of an error, make one and set the has_errors flag of it. (Target_arm::do_finalize_sections): Fix up links of EXIDX sections in a relocatable link. (Target_arm::do_relax): Look for the EXIDX output section instead of assuming that it is called .ARM.exidx. (Target_arm::fix_exidx_coverage): Add a new parameter for input section list. Do not check for SHF_EXECINSTR section flags but skip any input section with errors. * output.cc (Output_section::Output_section): Initialize always_keeps_input_sections_ to false. (Output_section::add_input_section): Check for always_keeps_input_sections_. * output.h (Output_section::always_keeps_input_sections, Output_section::set_always_keeps_input_sections): New methods. (Output_section::always_keeps_input_sections): New data member.
