gcc/testsuite/ChangeLog:
* gcc.dg/vect/bb-slp-subgroups-3.c: Add !vect128.
/* Because we disable the cost model, targets with variable-length
vectors can end up vectorizing the store to a[0..7] on its own.
With the cost model we do something sensible. */
-/* { dg-final { scan-tree-dump-times "optimized: basic block" 2 "slp2" { target { ! amdgcn-*-* } xfail vect_variable_length } } } */
+/* { dg-final { scan-tree-dump-times "optimized: basic block" 2 "slp2" { target { ! amdgcn-*-* } xfail { vect_variable_length && { ! vect128 } } } } } */
/* amdgcn can do this in one vector. */
/* { dg-final { scan-tree-dump-times "optimized: basic block" 1 "slp2" { target amdgcn-*-* } } } */
