[PATCH] D82663: [CodeGen] Have CodeGen for fixed-point unsigned with padding emit signed operations.

[Bevin Hansson via Phabricator via cfe-commits]

ebevhan added a comment.

Well, it's not so much as adding the bit, but adding the information that the bit exists. That means either new intrinsics for all of the operations, or adding flags to the existing ones. That's a fair bit of added complexity. Also, <signed operation> + <clamp to zero> would do virtually the exact same thing as the new unsigned-with-padding operations, so the utility of adding all of it is a bit questionable.
