[cfe-dev] why does clang re-evaluate the target info for each input file?

The subject line says it all, I suppose.  It seems to me that the target
would be a per-invocation constant.  Is state modified that needs to be

  for (unsigned i = 0, e = InputFilenames.size(); i != e; ++i) {
    const std::string &InFile = InputFilenames[i];
    <if not a serialized file> {
      Target = TargetInfo::CreateTargetInfo(&triples[0],

If we want to optimize for the serialized case, perhaps we could allocate
the target information lazily?
