Looking around, I came across this
<https://www.linaro.org/blog/comparing-llvm-flang-with-other-fortran-compilers/>,
from just a few months ago. Seems there is “Classic Flang” and “LLVM
Flang”: the latter is an all-new compiler, but its performance is not
there yet.

Also looks like Gfortran is roughly as good as “Classic Flang”, if not
better than it in some places.

Which Flang will VSI be using?
