* Provide dbgs(), a circular-buffering debug output stream. By default itDavid Greene2009-12-231-1/+55
| | | | | | | | | simply passes output to errs(). If -debug-buffer-size=N is set N > 0, dbgs() buffers its output until program termination and dumps the last N characters sent to it. This is handy when debugging very large inputs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92002 91177308-0d34-0410-b5e6-96231b3b80d8
* Add circular_raw_ostream, which buffers its output in a circular queueDavid Greene2009-12-231-0/+47
| | | | | | | | | and outputs it when explicitly flushed. The intent is to use it in situations such as debug output logging where a signal handler can take care of flushing the buffer at program termination. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92001 91177308-0d34-0410-b5e6-96231b3b80d8
