--- Comment #4 from Matthias Kretz (Vir) <mkretz at gcc dot gnu.org> --- The use of the builtins is not the point of this PR. The point is the conversion to the matching GNU vector type. If it helps I can change the test case to use a user-defined function rather than a builtin. The problem is the same.
