* formatted_raw_ostream both is-a raw_ostream and has-a raw_ostream. ThisDan Gohman2009-07-161-3/+24
| | | | | | | | | | | | | | | | means that two separate raw_ostreams are doing buffering before data is sent to the underlying stream. Besides the inefficiency of redundant buffering, the second level of buffering doesn't recieve flush() requests. Fix this by having formatted_raw_ostream set the underlying raw_ostream to be unbuffered. This eliminates inefficiency due to redundant buffering, and it makes the flush() disconnect harmless. This fixes PR4559. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75883 91177308-0d34-0410-b5e6-96231b3b80d8
