================ Comment at: llvm/test/CodeGen/PowerPC/LowerCheckedFPArith.ll:36 +; CHECK-NEXT: %2 = fdiv fast float %0, %1 +; CHECK-NEXT: %3 = fcmp une float %2, %2 +; CHECK-NEXT: br i1 %3, label %swdiv_HWDIV, label %swdiv_MERGE ---------------- A "fast" fdiv never produces NaN, per LangRef. Using fcmp like this is fragile at best. (Maybe you want "fdiv arcp"?)
