Author: dim Date: Wed Dec 11 07:34:34 2013 New Revision: 259214 URL: http://svnweb.freebsd.org/changeset/base/259214 Log: MFC r259100: Pull in r196658 from upstream clang trunk: CodeGen: Don't emit linkage on thunks that aren't emitted because they're vararg. This can happen when we're trying to emit a thunk with available_externally linkage with optimization enabled but bail because it doesn't make sense for vararg functions. [LLVM] PR18098. This should fix clang "Broken module found, compilation aborted" errors when building the qt4-based dvbcut port.
