AMD today went public with details on the "AMD Next-Gen Fortran Compiler" as a new Fortran compiler they are working on based on LLVM's Flang.

The AMD Next-Gen Fortran Compiler is a new open-source Fortran compiler focused on OpenMP offloading to AMD GPUs with a direct interface to ROCm and HIP.

This downstream of Flang is focused on AMD GPU offloading and interacting with the ROCm compute stack. This downstream is open-source and tested across various Linux distributions while using the ROCm driver.

This is akin to AMD's [1]AOMP compiler efforts as their LLVM downstream focused on providing the latest OpenMP offload support to AMD GPUs... But at least for now this "next-gen" compiler is being developed via a separate codebase from AOMP.

This also isn't to be confused with AMD's CPU compiler efforts... Over in [2]AOCC land for the AMD Optimizing C/C++ Compiler they have already been shipping a Flang version for Fortran support catered to the AMD Zen-based processors. But with this Next-Gen Fortran Compiler it's on the GPU front. Yes, AMD's multiple downstreams of LLVM for different product families can get a bit confusing and overlapping in some areas.

AMD today published [3]this ROCm blog post outlining their Next-Gen Fortran Compiler. For now at least the GitHub repository being worked on for this new Fortran compiler is under [4]AMD's InfinityHub CI tree .
