It'd be nice if its framework can be re-used for target-specific passes, doing quirky sign- or zero-extend- related optimizations (those that are not just sign- or zero-extend removal). Perhaps most of those opportunities can be implemented as target hooks in this pass. Definitely not asking for a change, just imagining future improvements. Also, I haven't followed the thread and its branches, just offering a word encouragement. brgds, H-P
