I think the answer is "yes" for both questions, thanks for your reports! A year ago when I bothered about regtesting with -fcompare-debug I've creat= ed a few issues unrelated to modulo scheduler and Jakub fixed most of them. Short summary is available at https://gcc.gnu.org/pipermail/gcc-patches/2020-March/542389.html, there I've also investigated everything on modulo sched side, but small patch2.txt was never committed. Given now we are in stage1 and have three PRs (I'll check PR100533 and PR100523, they should be same), now it's time to push that.=
