// 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.
