PR 11108
* symtab.h (class Symbol): Remove fields is_target_special_ and has_plt_offset_. Add field is_defined_in_discarded_section_. (Symbol::is_defined_in_discarded_section): New function. (Symbol::set_is_defined_in_discarded_section): New function. (Symbol::has_plt_offset): Rewrite. (Symbol::set_plt_offset): Verify that new offset is not -1U. * symtab.cc (Symbol::init_fields): Initialize plt_offset_ to -1U. Don't initialize is_target_special_ or has_plt_offset_. Initialize is_defined_in_discarded_section_. (Symbol_table::add_from_relobj): If appropriate, set is_defined_in_discarded_section. * resolve.cc (Symbol::override_base_with_special): Don't test is_target_special_. Change has_plt_offset_ to has_plt_offset(). * target-reloc.h (relocate_section): Do special handling for symbols defined in discarded sections for global symbols as well as local symbols.
