-// This file implements a handy 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 LLVM_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 without assertions, the -debug-* options and all code in 
-// LLVM_DEBUG() statements disappears, so it does not affect the runtime of the 
-// code.
