Semantic checks for OpenMP constructs are in progress. I believe checks and creation of symbols for reduction-based clauses will be happening soon.<br>
<br>
In case you are not aware, the llvm/flang project currently has only the parser and semantic checks enabled. For codegen, it uses an external compiler. By default, the external compiler is gfortran. But you can also set it to other compilers like AOCC using
an environment variable (F18_FC). AOCC is based on the Classic Flang project (<a href="https://github.com/flang-compiler/flang" id="LPlnk">https://github.com/flang-compiler/flang</a>) and not llvm/flang.<br>
