About:
Flang is the Fortran frontend for the LLVM compiler infrastructure. It parses and semantically analyzes Fortran code, converting it into an intermediate representation that can be optimized and compiled to machine code. This enables modern Fortran applications to leverage the powerful optimization and code generation capabilities of the LLVM backend.
Key Features:
  • Full Fortran 2018 standard compliance
  • Integration with LLVM optimization and code generation pipeline
  • Support for OpenMP and OpenACC directives
  • Modern C++ codebase with extensible architecture
Use Cases:
  • Compiling high-performance scientific computing applications
  • Migrating legacy Fortran codebases to modern toolchains
  • Developing mixed-language applications with C/C++ and Fortran
Alternatives:
  • gfortran – GNU Fortran compiler with broader platform support but different optimization pipeline
  • ifort – Intel Fortran compiler with vendor-specific optimizations for Intel hardware
