Thanks @pawosm01



================
Comment at: llvm/test/Transforms/InstCombine/pow-4.ll:140
+; CHECK-NEXT:    [[TMP1:%.*]] = call fast double @llvm.pow.f64(double [[X:%.*]], double 1.650000e+01)
+; CHECK-NEXT:    ret double [[TMP1]]
 ;
----------------
I guess we need to decide whether we want to retain this variety of cases somehow? I assume we can perform this as powi(x, 16) * sqrt(x) ?
