2004-05-03 Paolo Carlini <pcarlini@suse.de> Optimize locale::_M_impl->_M_names for the most common cases: !_M_names[0] means unnamed; !_M_names[1] means all the categories the same name (_M_names[0] && _M_names[1] means that the full set of _M_names must be processed, the general case). * include/bits/locale_classes.h (locale::_Impl::_M_check_same_name): Tweak, saving work when !_M_names[1]. (locale::locale(const locale&, _Facet*): Simplify: now just setting _M_names[0] = 0 means unnamed. * src/locale.cc (locale::operator==): Deal first with the common, easy cases, otherwise fall back to locale::name(). (locale::name()): Tweak, if !_M_names[0] just return "*". (locale::_Impl::_Impl(const _Impl&, size_t): Tweak, early stop copying __imp._M_names if !__imp._M_names[0] or !__imp._M_names[1]. * src/locale_init.cc (locale::_Impl::_Impl(size_t)): Tweak. * src/localename.cc (locale::_Impl::_Impl(const char*, size_t): Simplify when !std::strchr, just updating _M_names[0]; clean up. (locale::_Impl::_M_replace_categories): When !_M_names[1] prepare for the general case (full set of names), then do the usual work; clean up. * src/locale.cc (locale::name()): Reserve space in __ret. * src/locale_init.cc (locale::global(const locale&)): Save the name in a temporary. * src/localename.cc (locale::locale(const char*)): Reserve space in __str.
