--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
It's because we do
if (slp_node
&& !(!single_defuse_cycle
&& !lane_reduc_code_p
&& reduction_type != FOLD_LEFT_REDUCTION))
for (i = 0; i < (int) op.num_ops; i++)
if (!vect_maybe_update_slp_op_vectype (slp_op[i], vectype_op[i]))
{
if (dump_enabled_p ())
dump_printf_loc (MSG_MISSED_OPTIMIZATION, vect_location,
"incompatible vector types for invariants\n");
return false;
}
for the invariant lower precision op of the reduction. Arguably that's
not efficient. We're detecting a widen_sum from
n.0_1 = n;
_2 = (int) n.0_1;
m_lsm.19_13 = m;
<bb 3> [local count: 1073741824]:
# iter.6_8 = PHI <0(2), iter.6_9(5)>
# m_lsm.19_12 = PHI <m_lsm.19_13(2), _5(5)>
# ivtmp_7 = PHI <2(2), ivtmp_18(5)>
_4 = _2 + m_lsm.19_12;
which is where we could fix this. I have a patch for the reduction code
for now.

tree-optimization/108950 - widen-sum reduction ICE
When we end up with a widen-sum with an invariant smaller operand
the reduction code uses a wrong vector type for it, causing
IL checking ICEs. The following fixes that and the inefficiency
of using a widen-sum with a widenend invariant operand as well
by actually performing the check the following comment wants.
PR tree-optimization/108950
* tree-vect-patterns.cc (vect_recog_widen_sum_pattern):
Check oprnd0 is defined in the loop.
* tree-vect-loop.cc (vectorizable_reduction): Record all
operands vector types, compute that of invariants and
properly update their SLP nodes.
* gcc.dg/vect/pr108950.c: New testcase.
