	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.
void	llvm::setCurrentDebugType (const char *Type)
	setCurrentDebugType - Set the current debug type, as if the -debug-only=X option were specified.
void	llvm::setCurrentDebugTypes (const char **Types, unsigned Count)
	setCurrentDebugTypes - Set the current debug type, as if the -debug-only=X,Y,Z option were specified.
raw_ostream &	llvm::dbgs ()
	dbgs() - This returns a reference to a raw_ostream for debugging messages.

Variables
bool	llvm::DebugFlag = false
	This boolean is set to true if the '-debug' command line option is specified.
bool	llvm::EnableDebugBuffering = false

DEBUG_WITH_TYPE

#define DEBUG_WITH_TYPE	(		TYPE,
			X
	)

Value:

  do { if (::llvm::DebugFlag && ::llvm::isCurrentDebugType(TYPE)) { X; } \
  } while (false)

DEBUG_WITH_TYPE 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_WITH_TYPE("bitset", dbgs() << "Bitset contains: " << Bitset << "\n");

This will emit the debug information if -debug is present, and -debug-only is not specified, or is specified as "bitset".
