-  // FIXME: For now we want to demote any errors to warnings, when they have
-  // been raised for asking the wrong question of scalable vectors, such as
-  // asking for the fixed number of elements. This may happen because code that
-  // is not yet ported to work for scalable vectors uses the wrong interfaces,
-  // whereas the behaviour is actually correct. Emitting a warning helps bring
-  // up scalable vector support in an incremental way. When scalable vector
-  // support is stable enough, all uses of wrong interfaces should be considered
-  // as errors, but until then, we can live with a warning being emitted by the
-  // compiler. This way, Clang can be used to compile code with scalable vectors
-  // and identify possible issues.
