Provide dbgs(), a circular-buffering debug output stream. By default it 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
