Myers <ncm-nospam@cantrip.org> PR libstdc++/11378 * include/std/std_fstream.h (xsputn): Declare only. * include/bits/fstream.tcc (xsputn): Define, optimize for the always_noconv() case: when __n is sufficiently large flush the buffer and issue a direct write, if possible combining the two with writev in __basic_file<>::xsputn_2. * config/io/basic_file_stdio.h (__basic_file<>::xsputn_2): New, declare. * config/io/basic_file_stdio.cc (__basic_file<>::xsputn_2): Define. * acinclude.m4 (GLIBCXX_CHECK_WRITE): New macro, checking for the availability of writev in <sys/uio.h>. * configure.in: Call here. * acconfig.h: Add undef for the corresponding symbol. * aclocal.m4: Regenerate. * configure: Regenerate. * config.h.in: Regenerate. * testsuite/27_io/basic_filebuf/setbuf/char/3.cc: Tweak. * include/std/std_fstream.h (sync): Constify a variable.
