of 2009-12-30. (Version_script_info::Version_script_info): Initialize globs_, default_version_, default_is_global_, and exact_. Don't initialize globals_ or locals_. (Version_script_info::build_lookup_tables): Build local symbols first. (Version_script_info::unquote): New function. (Version_script_info::add_exact_match): New function. (Version_script_info::build_expression_list_lookup): Remove lookup parameter. Add is_global parameter. Change all callers. Handle wildcard pattern specially. Unquote pattern. Call add_exact_match.

(Version_script_info::check_unmatched_names): Call unquote. * script.h (class Version_script_info): Change get_symbol_version to be non-inline and add is_global parameter; change all callers. Rewrite symbol_is_local. Update declarations. Define struct Version_tree_match, Exact, Globs. Don't define struct Lookup. Remove globals_ and locals_ members. Add exact_, globs_, default_version_, is_global_. (Version_script_info::Glob): Remove pattern, add expression and is_global. Update constructor. Change all callers. * dynobj.cc (Versions::finalize): Mark the version symbol as the default version. (Versions::symbol_section_contents): If a symbol is undefined, or defined in a dynamic object, set the version index to VER_NDX_LOCAL. * symtab.cc (Symbol_table::add_from_relobj): Don't call symbol_is_local.
