@llvm/pr-subscribers-flang-fir-hlfir @llvm/pr-subscribers-flang-codegen Author: Alexis Perry-Holby (AlexisPerry) ChangesThis PR adds -mtune as a valid flang flag and passes the information through to LLVM IR as an attribute on all functions. No specific architecture optimizations are added at this time.
