From 2f3a07a981edfbc325f19ea252003e9da59dbcf5 Mon Sep 17 00:00:00 2001 From: Tin Huynh Date: Fri, 4 Aug 2017 17:50:09 -0700 Subject: Flang: Add support for flang Fortran compiler flang is a Fortran compiler built on top of clang [1]. Because flang shares a lot of commonalities with clang, the flang module piggybacks off the clang module and overrides certain options. Add flang to Fortran compiler auto find list. Update flang preprocessor macros to differentiate from PGI. Add Flang-FindBinUtils.
