[Flang-dev] [llvm-dev] flang in llvm.org source tree

That’s the flang that’s presently in use by anyone who says they are using flang.  ;)

But there is also https://github.com/flang-compiler/f18 which is a newer flang.

Since you asked when flang would be added to llvm.org, Dave was trying to point out that the older of the two probably would never land there, since there is a newer one in development.

The older one likely has recent commits, too, because that’s the one that can be more readily used at the moment.

Now I'm really confused as the 'flang' compiler here has lots of recent commits from the Portland Group...

Seems like this should also go to flang-dev so I'm adding it.

"flang" is basically a legacy project.  "f18" is the new ground-up build
of a Fortran LLVM project.  f18 is the thing that has the most
likelihood of becoming an "official" LLVM project.

However, it's probably going to be a while before we get there.  For one
thing, I haven't seen any posts on flang-dev that talk about making
changes to f18, proposing designs, etc.  The development seems
completely opaque right now, which is unfortunate.

I would like to see f18 become "official" sooner rather than later, both
to open up development and to get better code sharing across projects.
