Re: Manually set sret parameter

Thank you so much for the help! It seems like the TREE_ADDRESSABLE bit is indeed what we have been looking for. In regards to your questions: Sadly, most of this is barely documented if at all. The rust compiler documentation is... not good. I only know about this because somebody mentioned this
