flang project was going to port PGI's frontend to use llvm as it middle/backend. A part of the port was to update PGI bits to include modern Fortran. The flang developers have decided to write an entirely new, from scratch, frontend. My conclusion is our 15+ year-old decisions and the addition of newer features (both modern Fortran and legacy) have complicated parts of the compiler to an almost unmanageable state. You can probably appreciate this better than most of us. -- Steve
