--- Comment #3 from Marc Glisse <glisse at gcc dot gnu.org> ---
I wonder if it would take more than replacing:
inc = integer_one_node;
with something like:
inc = VECTOR_TYPE_P (argtype)
? build_one_cst (argtype)
: integer_one_node;
(or even unconditionally build_one_cst)
to support increment/decrement for vectors. We already support v=v+1, so it
wouldn't be a large extension.
