+ //===- Debug.h - An easy way to add debug output to your code ---*- C++ -*-===//
+ //
+ // 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.
+ //

+ // isCurrentDebugType - Return true if the specified string is the debug type
+ // specified on the command line, or if none was specified on the command line
+ // with the -debug-only=X option.

+ bool isCurrentDebugType(const char *Type);
+ 
+ // DEBUG macro - This macro should be used by passes to emit debug information.
+ // In the '-debug' option is specified on the commandline, and if this is a
+ // debug build, then the code specified as the option to the macro will be
+ // executed.  Otherwise it will not be.  Example:
+ //
+ // DEBUG(cerr << "Bitset contains: " << Bitset << "\n");
