* target-reloc.h (relocate_section): Check the symbol table index
for -1U before setting the local symbol index.
(scan_relocatable_relocs): If copying the relocation, record that
the local symbol is required.
* object.h (Symbol_value::is_output_symtab_index_set): New
function.
(Symbol_value::may_be_discarded_from_output_symtab): New
function.
(Symbol_value::has_output_symtab_entry): New function.
(Symbol_value::needs_output_symtab_entry): Remove.
(Symbol_value::output_symtab_index): Make sure the symbol index is
set.
(Symbol_value::set_output_symtab_index): Make sure the symbol
index is not set. Make sure the new index is valid.
(Symbol_value::set_must_have_output_symtab_entry): New function.
(Symbol_value::has_output_dynsym_entry): New function.
(Symbol_value::set_output_dynsym_index): Make sure the new index
is valid.
(Sized_relobj::set_must_have_output_symtab_entry): New function.
* object.cc (Sized_relobj::do_count_local_symbols): Only discard a
local symbol if permitted.
(Sized_relobj::do_finalize_local_symbols): Call
is_output_symtab_index_set rather than needs_output_symtab_entry.
(Sized_relobj::write_local_symbols): Call has_output_symtab_entry
rather than needs_output_symtab_entry. Call
has_output_dynsym_entry rather than needs_output_dynsym_entry.
* arm.cc (Arm_relobj::update_output_local_symbol_count): Call
is_output_symtab_index_set rather than needs_output_symtab_entry.
* testsuite/discard_locals_relocatable_test.c: New file.
* testsuite/discard_locals_test.sh: Test -r.
* testsuite/Makefile.am (check_DATA): Add
discard_locals_relocatable_test1.syms,
discard_local_relocatable_test2.syms.
(MOSTLYCLEANFILES): Likewise. Also add
discard_locals_relocatable_test1.lout and
discard_locals_relocatable_test2.out.
(discard_locals_relocatable_test1.syms): New target.
(discard_locals_relocatable_test.o): New target.
(discard_locals_relocatable_test1.out): New target.
(discard_locals_relocatable_test2.syms): New target.
(discard_locals_relocatable_test2.out): New target.
(various): Add missing ../ld-new dependencies.
* testsuite/Makefile.in: Rebuild.
