Welcome to Flang's documentation
Flang is LLVM's Fortran frontend that can be found here. It is often referred to as "LLVM Flang" to differentiate itself from "Classic Flang" - these are two separate and independent Fortran compilers. LLVM Flang is under active development. While it is capable of generating executables for a number of examples, some functionality is still missing. See GettingInvolved for tips on how to get in touch with us and to learn more about the current status.
