I believe the overloaded forms for LUTI have been removed a few days ago as per https://github.com/ARM-software/acle/pull/278/files#diff-516526d4a18101dc85300bc2033d0f86dc46c505b7510a7694baabea851aedfaR11241-R11245, unless I've misread the latest change to the ACLE (I believe things in square brackets represent the overloaded forms?)
