2003-11-24 Paolo Carlini <pcarlini@suse.de> * config/locale/gnu/codecvt_members.cc (codecvt::do_in): Rewrite, using both mbsnrtowcs and mbrtowc in a loop: the former is very fast, but stops if encounters a NUL. (codecvt::do_out): Tweak. * testsuite/performance/wchar_t_in.cc: New. 2003-11-24 Paolo Carlini <pcarlini@suse.de> * include/bits/locale_facets.h (__numpunct_cache<>::_M_cache): Set _M_allocated at the beginning in order to avoid memory leaks; simplify a bit.
