My patch deprecates it in all cases currently. It will be a good warning for people that it will go away in the future (even if we don't yet agree on when exactly). > I have only seen use of this outside of just testing and inside > Samsung and Huawei but for the most part both of them have not done > any maintenance to support ILP32.

I agree there is no point in fixing any of this. It's never going to work without somebody doing a full port and active maintenance. There are lots of uses of unsigned long in libatomic - and all of those are incorrect in ILP32. And the assembler would need argument checks etc... Thinking it will work fine if it builds without errors is insanity. Cheers, Wilco
