You can do inlining even when flag_unit_at_a_time is off. And one can enable unit-at-a-time without enabling any optimizations. The unit-at- a-time is not meant to select optimization passes, though it may

After looking at the Livermore for a while, we found the issue that was causing LTO to produce a different result. Consider the code below [1]. setup() doesn't touch bar/baz, main() doesn't reference foo. LTO finds, correctly, that it can remove the setup(), but the result is different. The code is clearly wrong, but the compiler has no right to fix user's stupidity, even at that

Andy and I briefly discussed this the other day, we have not yet got chance to list a detailed pass order for the pre- and post- IPO scalar optimizations. This is wish-list in our mind: pre-IPO: based on the ordering he propose, get rid of the inlining (or just inline tiny func), get rid of all loop xforms... post-IPO: get rid of inlining, or maybe we still need it, only
