    hello there, i'm new to llvm and f18, i have installed f18 and it can generate IR by -llvm-emit option(which means it can generate ast either).
But unlike clang, it can't use -ast-dump to translate code to ast.
I also tried -q , -qq, -Hq, -Mq options, which are unknow argument.
By the way, i have found a article about flang names 
"How The Flang Frontend Works",
(https://llvm-hpc4-workshop.github.io/slides/Osmialowski.pdf) 
and i wonder whether f18 still has flang1 and flang2? 
Thank you very much for answering this question!
