+The summary is parsed into a bitcode output, along with the Module
 IR, via the "``llvm-as``" tool. Tools that parse the Module IR for the purposes
 of optimization (e.g. "``clang -x ir``" and "``opt``"), will ignore the
 summary entries (just as they currently ignore summary entries in a bitcode
 input file).
