Fort vs Other Open Source Compilers |
/comparison/ |
Pro's of Flang vs Fort:
- Much more complete Fortran support (though less than that of GNU Fortran)
Pro's of Fort vs Flang:
- Fort, just like Clang, is designed to be easily understandable; it has virtually no learning curve for developers familiar with LLVM or Clang
- Fort implements its own compilation pipeline (rather than piggy-backing on Clang) which reduces complexity of the project and allows for faster builds
- Fort compiles against LLVM components and produces LLVM IR in memory, which allows catching many of potential IR issues at compile time
- Fort follows LLVM release lifecycle from get-go
- Fort supports all LLVM targets
- Flang emits LLVM IR as text, which is error-prone and often forces to check output only at runtime
- Fort uses LLVM diagnostics
- Tooling API
Note: it was recently announced that Nvidia is undertaking some form of a rewrite of Flang. Stay tuned for updates to the comparison.
Pro's of GNU Fortran vs fort:
- Much more complete Fortran support
- GNU Fortran (and GCC in general) supports more targets
Pro's of fort vs GNU Fortran:
- Fort ASTs and design are intended to be easily understandable
- Fort is designed as an API, which allows it to be used as a foundation for other tools
- BSD-style license (can be embedded in other products)
- Clear and concise diagnostics
