If those "optimized out"s are an obstacle we should report them to the
GCC developers. I debugged Emacs with -Og, found an instance of
"optimized out", turned it into a small test case, and filed a bug

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78685
Please feel free to add to it, or to report more bugs in this area.
