// Instead of a single "NOT" check for this run, we would really want to check
// for all of the driver arguments that we _do_ expect, and then use an
// --implicit-check-not to check that -lc++ doesn't occur.
// However, --implicit-check-not has a bug where it fails to flag the
// unexpected text when it occurs after text matched by a CHECK-DAG; see
// https://bugs.llvm.org/show_bug.cgi?id=45629
// For this reason, we use a single "NOT" check for the time being here.
// The same consideration applies to the Linux and Windows cases below.
