Package Details

• Package Name/Version: llvm-flang/12.0.1
• Website: https://releases.llvm.org/11.0.0/tools/flang/docs/index.html
• Source code: https://github.com/llvm/llvm-project/tree/main/flang

Description Of The Library / Tool

Flang is a ground-up implementation of a Fortran front end written in modern C++. It started off as the f18 project (https://github.com/flang-compiler/f18) with an aim to replace the previous flang project (https://github.com/flang-compiler/flang) and address its various deficiencies. F18 was subsequently accepted into the LLVM project and rechristened as Flang.

Relates to the work done in the following:

• [request] libclang/9.0.0 #683
• llvm 10.0.0 #1450
• Add recipe for the LLVM core libraries #3375

And may serve the interests of the following:

• An alternative to gfortran, which appears to presently have a broken recipe
• [OpenBLAS] conanfile.py assumes gfortran compiler #1867
• [request] lapack/3.9.0 #4509

Flang is not yet able to generate LLVM IR for the source code and thus is unable to compile a running binary.

It's useless for now in a production environment. It just calls gfortran.
