Fix placement of forced local symbols in the dynamic symbol table.
Gold was not placing forced-local symbols (e.g., hidden visibility) at the front of the dynamic symbol table, or including them in the count of local symbols recorded in the .dynsym section's sh_info field. gold/ * layout.cc (Layout::finalize): Track count of forced-local symbols in .dynsym. (Layout::create_symtab_sections): Add local_dynamic_count parameter; use that instead of sh_info value. (Layout::create_dynamic_symtab): Add pforced_local_dynamic_count parameter; pass it to Symtab::set_dynsym_indexes(). Include forced locals in sh_info value. Pass index of first real global to Dynobj::create_gnu_hash_table() and Dynobj::create_elf_hash_table(). * layout.h (Layout::create_symtab_sections): Add local_dynamic_count parameter. (Layout::create_dynamic_symtab): Add pforced_local_dynamic_count parameter. * symtab.cc (Symbol_table::set_dynsym_indexes): Add pforced_local_count parameter. Process forced-local symbols first and return the count. (Symbol_table::finalize): Update comments. * symtab.h (Symbol_table::set_dynsym_indexes): Add pforced_local_count parameter. (Symbol_table::first_dynamic_global_index_): Update comment. (Symbol_table::dynamic_count_): Update comment. * testsuite/Makefile.am (ifuncmod1.sh): New test case. * testsuite/Makefile.in: Regenerate. * testsuite/ifuncmod1.sh: New shell script.
