An analysis pass which caches information about the entire Module.
Records both the function level information used by GCRoots and a cache of the 'active' gc strategy objects for the current Module.
Definition at line 155 of file GCMetadata.h.
| typedef std::vector<std::unique_ptr<GCFunctionInfo> > llvm::GCModuleInfo::FuncInfoVec |
List of per function info objects.
In theory, Each of these may be associated with a different GC.

begin/end - Iterators for used strategies.
Definition at line 197 of file GCMetadata.h.
Referenced by llvm::AsmPrinter::doFinalization().
| void GCModuleInfo::clear | ( | ) |
clear - Resets the pass.
Any pass, which uses GCModuleInfo, should call it in doFinalization().

get - Look up function metadata.
This is currently assumed have the side effect of initializing the associated GCStrategy. That will soon change.

| GCStrategy * GCModuleInfo::getGCStrategy | ( | const StringRef | Name | ) |
Lookup the GCStrategy object associated with the given gc name.
Objects are owned internally; No caller should attempt to delete the returned objects.
