   3 // This tests that types are propagated from symbols to their aliases. Our
   4 // behavior is a bit different than gas. If the type of a symbol changes,
   5 // gas will update the type of the aliases only if those aliases were declare
   6 // at a point in the file where the aliased symbol was already define.
   7
   8 // The lines marked with GAS illustrate this difference.
