+
+The '``llvm.vector.reduce.fmaximum.*``' intrinsics do a floating-point
+``MAX`` reduction of a vector, returning the result as a scalar. The return type
+matches the element-type of the vector input.
+
+This instruction has the same comparison semantics as the '``llvm.maximum.*``'
+intrinsic. That is, this intrinsic propagates NaNs and +0.0 is considered
+greater than -0.0. If any element of the vector is a NaN, the result is NaN.
+
+If the intrinsic call has the ``nnan`` fast-math flag, then the operation can
