Daniel Dunbar 84e383fc42 Don't allow formatted_ostream to be unbuffered, even if its underlying buffer ... is. - The problem is that formatted_ostream forces its underlying buffer to be unbuffered, so if some client happens to wrap a formatted_ostream around something, but still use the underlying stream, then we can end up writing on a fully unbuffered output (which was never intended to be unbuffered). - This makes clang (and presumably llvm-gcc) -emit-llvm -S a mere 10x faster. llvm-svn: 82434		2009-09-21 03:56:00 +00:00
