================
Comment at: llvm/include/llvm/IR/PatternMatch.h:616-620
+/// For vectors, this includes constants with undefined elements.
+inline cstfp_pred_ty<is_finite> m_Finite() {
+  return cstfp_pred_ty<is_finite>();
+}
+inline apf_pred_ty<is_finite> m_Finite(const APFloat *&V) { return V; }

Correct. m_Finite() does, m_Finite(const APFloat *&) does not. This is the pre-existing problem I mentioned which has now been copied across from the integer matchers to the fp ones.
