Flang should be able to compile most of CPU2017 if not all of them.

We are using Dragonegg in our academic research, because we are using SPEC CPU2006 for benchmarking. CPU2006 has many FP benchmarks written in Fortran, and this is still the case in CPU2017. Half of the FP benchmarks in CPU2017 have Fortran code. We are not particularly interested in Fortran, but I assume that this benchmark selection reflects the fact that a lot of important scientific programs are written in Fortran. We will be happy to use Flang as soon as it is ready and capable of compiling CPU2017. Our life will be much easier with a native Fortran front end.
