+ //===-- Debug.cpp - An easy way to add debug output to your code ----------===//
+ //
+ // This file implements a handle way of adding debugging information to your
+ // code, without it being enabled all of the time, and without having to add
+ // command line options to enable it.
+ //
+ // In particular, just wrap your code with the DEBUG() macro, and it will be
+ // enabled automatically if you specify '-debug' on the command-line.
+ // Alternatively, you can also use the SET_DEBUG_TYPE("foo") macro to specify
+ // that your debug code belongs to class "foo".  Then, on the command line, you
+ // can specify '-debug-only=foo' to enable JUST the debug information for the
+ // foo class.
+ //
+ // When compiling in release mode, the -debug-* options and all code in DEBUG()
+ // statements disappears, so it does not effect the runtime of the code.
+ //

+       DebugFlag |= !Val.empty();
+       CurrentDebugType = Val;
+     }
+   } DebugOnlyOptLoc;

+   DebugOnly("debug-only", cl::desc("Enable a specific type of debug output"),
