Some time ago, SBLionel mentioned in this Discourse group:.
Now with the move to LLVM, there is still no compile-time detection,
but a fairly robust run-time detection.
I would be thrilled to have runtime detection. Does it work?
Is there a downloadable package or binary for LLVM Fortran?
So far I can only find information for compiler developers. I
know that Fortran for LLVM is not complete yet, but my
program is pretty simple (if large) and I could probably
adapt it anyway.
