This should be main motivation for replacing built-ins. But this approach IMHO should only be used for `obvious' cases only. I mean: + - / * and friends. Think that this shouldn't apply for shuffles, broadcasts. But we have to define border between `obvious' and rest intrinsics.
On the over hand, updated in such a way intrinsic may actually generate different instruction then intended (e.g. FMA case). For ICC this is generally OK to generate different instructions, only semantics should be obeyed. -- Thanks, K
