Thanks for all this work. So I've checked a few random archs and trust your tests above to confirm they're correct ;-) I'd just like to get your confirmation regarding statx() support in 4.14 and 4.19, and likely adjust _start_c() according to the last few tests. Also please do prepend to the list the patch that adds the optimize("-Os") to fix _start, and we should be good. Thanks! Willy
