Thank you @RosieSumpter, this patch looks good to me and I think all of the comments have been addressed.



================
Comment at: llvm/test/Transforms/LoopVectorize/AArch64/strict-fadd.ll:854
+; CHECK-UNORDERED: [[FADD4]] = fadd nnan float [[LOAD4]], [[VEC_PHI4]]
+; CHECK-UNORDERED-NOT: call fast float @llvm.vector.reduce.fadd
+; CHECK-UNORDERED: middle.block:
----------------
Should `fast` here be replaced with `nnan`?
