[PATCH] D36800: Add rewrite by-reference parameter pass

[Tobias Grosser via Phabricator via llvm-commits]

It's certainly not too late. Until now it seemed to me like a very specific optimization for gfortran. I did not see any such examples before. If we can generalize this, we can certainly try to upstream this. Could you share some of the examples you are seeing?
