--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Note for gcc.dg/vect/vect-gather-4.c with -mgather and gather support in the
ISA on x86_64 I get two 'vectorizing stmts using SLP', for f1 and f2 only.

Does that match GCN?

We unfortunately cannot handle masked gathers as "emulated".

And we don't have good dejagnu target selectors for this either.
