From 85749766dff084e433f05b23f9b93c28704ab014 Mon Sep 17 00:00:00 2001 From: Tin Huynh Date: Wed, 7 Jul 2021 18:20:36 -0700 Subject: LLVMFlang: Add support for LLVM Flang LLVM Flang (https://github.com/llvm/llvm-project/tree/main/flang) is an LLVM Fortran compiler that shares the same name as Flang (also known as Classic Flang). Classic Flang is in active development and is already identified by CMake as Flang. As such, LLVM Flang will be identified as `LLVMFlang`.
