--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
Interesting the only effect could be different GC allocation pattern because
the non-splice variant may end up re-allocating the target vector multiple
times.  But this alone should never change code generation.

So - can you share a preprocessed file where code generation changes with
this revision?
