// The abstract base class GCMetadataPrinter supports writing GC metadata tables
// as assembly code. This is a separate class from GCStrategy in order to allow
// users of the LLVM JIT to avoid linking with the AsmWriter.
//
// Subclasses of GCMetadataPrinter must be registered using the
// GCMetadataPrinterRegistry. This is separate from the GCStrategy itself
// because these subclasses are logically plugins for the AsmWriter.
