--- Comment #7 from Johannes M Dieterich <jmd@freebsd.org> ---
As the maintainer of devel/flang I agree with Steve here. flang is a) not y=
et
ready to replace gfortran (for the reasons Steve discussed) and b) only
available for amd64. Personally, I hope this will change eventually and I h=
ope
we (as in FreeBSD) can help upstream by filing bug reports and vetting the
compiler.

I assume that you, Steve, filed these 100 internal compiler errors with fla=
ng
upstream so that we can track progress?

Alternatively, could we get the Fortran test suite into the ports tree? I
wouldn't mind having that myself to check flang updates.

I see as a more viable alternative to get BLAS and LAPACK to Fortran-free
implementations and am working on making blis and flame viable. Reference
source-code implementations for BLAS/LAPACK are anyways a bad idea to use in
production. That'll still leave a bunch of Fortran ports but at least it wo=
uld
be a start.
