--- Comment #2 from Rich Lowe <richlowe at richlowe dot net> --- I'm not certain -Og exactly matches what I wanted, though it's close. I was hoping to maintain the existing -O<N> I was specifying, but have those problematic optimizations disabled en-masse. Does -Og allow for that? (such that I would pass -O3 -Og, and get in effect -O3 -fno-ipa-cp -fno-ipa-icf etc.)
