tree-optimization/116647 - wrong classified double reduction
The following avoids classifying a double reduction that's not
actually a reduction in the outer loop (because its value isn't
used outside of the outer loop). This avoids us ICEing on the
unexpected stmt/SLP node arrangement.
PR tree-optimization/116647
* tree-vect-loop.cc (vect_is_simple_reduction): Add missing
check to double reduction detection.
* gcc.dg/torture/pr116647.c: New testcase.
* gcc.dg/vect/no-scevccp-pr86725-2.c: Adjust expected pattern.
* gcc.dg/vect/no-scevccp-pr86725-4.c: Likewise.
