poudriere log for a patched port
There are 2 issues with this patch: 1. The correct way to do this is using the port option FLANG, see math/R how this is done there. Please resubmit the patch doing this 2. Some people might disagree with this, not sure. This adds a certain level of complexity. Also, for this all ports that depend on lapack should probably be rebuilt and retested.

necessary changes for switching to flang
A less-destructive switch to flang (OPTION).

proper handling of non-supported archs
The patch no longer applies. I'm afraid it needs to be updated. There is no reason to refresh the patch yet. The thing that is now called "flang" is a completely different project than the one from back then in 2018. At the moment, the new Flang isn't able to compile anything, so it is impossible to switch to it. Once the new Flang matures, it will be included in the devel/llvmXX port (I presume), and then we will be able to make a switch. devel/flang expired today. (In reply to Rene Ladan from comment #8) Hopefully, at some point the devel/llvmXY port will eventually provide a new flang suitable to be hooked into USES=fortran (In reply to Gleb Popov from comment #9) LFortran seems very interesting: see <https://lfortran.org/>. Looking at other repos they use GCC 11 (or 12) with gfortran, is that still troublesome? I’d like to add at least one alternative in Mk/Uses/fortran.mk, maybe LFortran or flang-new, but they are not yet ready. Does openblas now require FLANG as openblas fails to build in poudriere on a system with the FLANG option disabled for LLVM.
