The compilers we build using the Rllvm approach may not cover all cases or out-perform the compiler package
That's okay! Users can choose which approach to use for each problem.
This is not a competition. The goal is to make code go faster, and fast enough to allow qualitatively new explorations.
Ideally, single approach to make things easier for user, but this can use different implementations - some more general, some faster by exploiting specifics.
