Selecting an ABI mode has wider reaching implications that are likely to come back to haunt me when I start to integrate with other binaries so I prefer not to ressort to it. It is also not addressing my needs if this is only handling zero-extension. As I am mostly using the high end of the aarch64 virtual space, what I need is sign-extension.
