With the [1]newly-released LLVM 20.1 compiler stack among the many changes throughout the massive codebase is [2]renaming the "flang-new" compiler just to "flang" . This new Flang compiler front-end has matured quite well over the years to providing robust and reliable Fortran language support within the confines of the LLVM toolchain.

In marking the LLVM 20 stable release and the milestone of flang-new renamed to flang, the LLVM Project blog has put out a blog post outlining all of the accomplishments for this modern Flang Fortran compiler.

Thanks to the work of NVIDIA, Arm, the US National Laboratories, and others, this modern Flang compiler has evolved very well into being a viable and full-featured open-source Fortran compiler.

Those interested in all of the fine details around this new "Flang" compiler in LLVM 20+ can read all about it on the [3]LLVM.org blog .
