In particular, Collector was confusing to implementors. Several thought that this compile-time class was the place to implement their runtime GC heap. Of course, it doesn't even exist at runtime. Specifically, the renames are: Collector -> GCStrategy CollectorMetadata -> GCFunctionInfo CollectorModuleMetadata -> GCModuleInfo CollectorRegistry -> GCRegistry Function::getCollector -> getGC (setGC, hasGC, clearGC) Several accessors and nested types have also been renamed to be consistent. These changes should be obvious. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54899 91177308-0d34-0410-b5e6-96231b3b80d8

// 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.
