 int subit(float a, float b, float *fp) {
-  // CHECKFAST: define {{.*}}@subit(float noundef %a, float noundef %b{{.*}}
+  // CHECKPRECISE: define {{.*}}@subit(float noundef %a, float noundef %b{{.*}}
   *fp = __arithmetic_fence(a - b);

The RUN at line 16 with -DFAST would generate a warning: "#pragma float_control is not supported on this target". That's why I separated that check from the others.
