This is better than current behavior, but this is not what I want. 15-byte function does not need to be aligned to 16 bytes on a machine with 128-byte L1I cachelines. It needs to be aligned to 128 bytes if there are less than 15 bytes remaining; if there are MORE than 15 bytes remaining, why align at all? It's a waste of space.
So that sounds like you'd want to modify the max_skip value based on the size of the function - which would be a fairly minor change. We could call that -falign-functions-max-skip-size or something like that.
