Duncan P. N. Exon Smith a59d3e5af8 DebugInfo: Remove MDString-based type references ... Eliminate DITypeIdentifierMap and make DITypeRef a thin wrapper around DIType*. It is no longer legal to refer to a DICompositeType by its 'identifier:', and DIBuilder no longer retains all types with an 'identifier:' automatically. Aside from the bitcode upgrade, this is mainly removing logic to resolve an MDString-based reference to an actualy DIType. The commits leading up to this have made the implicit type map in DICompileUnit's 'retainedTypes:' field superfluous. This does not remove DITypeRef, DIScopeRef, DINodeRef, and DITypeRefArray, or stop using them in DI-related metadata. Although as of this commit they aren't serving a useful purpose, there are patchces under review to reuse them for CodeView support. The tests in LLVM were updated with deref-typerefs.sh, which is attached to the thread "[RFC] Lazy-loading of debug info metadata": http://lists.llvm.org/pipermail/llvm-dev/2016-April/098318.html llvm-svn: 267296		2016-04-23 21:08:00 +00:00
