[PATCH] D103275: Update musttail verification to check all swiftasync->swiftasync tail calls.

[Arnold Schwaighofer via Phabricator via llvm-commits]

aschwaighofer added a comment.

I guess that the 'in tail position' restriction cannot really be used by frontends because it has to predict that `otherStuff()` cannot be optimized away. So it would not buy us much other than a loss of clarity ...

   if (cond) {
     swifttailcc();
     otherStuff();
     ret;
  }
