-Subject: [PATCH] tree-optimization/115395 - wrong-code with SLP reduction in
- epilog
-
-When we continue a non-SLP reduction from the main loop in the
-epilog with a SLP reduction we currently fail to handle an
-adjustment by the initial value because that's not a thing with SLP.
-As long as we have the possibility to mix SLP and non-SLP we have
-to handle it though.
-
-	PR tree-optimization/115395
-	* tree-vect-loop.cc (vect_create_epilog_for_reduction):
-	Handle STMT_VINFO_REDUC_EPILOGUE_ADJUSTMENT also for SLP
-	reductions of group_size one.
-
-	* gcc.dg/vect/pr115395.c: New testcase.
