Why would that be desirable? Seems to me the current situation is
clearly preferable.
To enable loop transforms in -O3.
Note that loop optimization

Thanks for the reply. On the other hand, it seems that PPL and Cloog
are auto-detected by configure; shouldn't that be enough to dynamically
modify what -O3 does (or perhaps enable -O4)? On a related point,

the prerequisites
