================
Comment at: test/Transforms/SLPVectorizer/X86/arith-add-ssat.ll:68
+; SLM-NEXT:    [[TMP3:%.*]] = call <8 x i64> @llvm.sadd.sat.v8i64(<8 x i64> [[TMP1]], <8 x i64> [[TMP2]])
+; SLM-NEXT:    store <8 x i64> [[TMP3]], <8 x i64>* bitcast ([8 x i64]* @c64 to <8 x i64>*), align 8
 ; SLM-NEXT:    ret void
----------------
This change is surprising, given how slow v2i64 ADD/SUB are on SLM
