Hmm... I haven't tried the lno-branch compiler. Lord knows, there
enough versions of GCC on my system already (12 at last count). I *am*
looking forward to vectorization.
According to the GCC docs, -ftree-loop-optimize is enabled at -O
tree-loop-optimize is new to the lno branch.
It's actually just turning on analysis.
higher. I'm not familiar with -fscalar-evolutions.
You don't need it, as the passes that require it (linear loop
transforms, vectorization) already turn it on automatically.
