Contributions summary:Tarun primarily contributed to the Flang compiler project by implementing features and addressing issues related to the Fortran language front-end and lower. The commits focused on lowering intrinsic functions, particularly the atan (y,x) form of the atan intrinsic, and incorporating support for command-line options like `-frecord-command-line`, `-nostdlib`, and `-nodefaultlibs`. The user also corrected test code and enhanced driver capabilities by adding support for options such as `-Qunused-arguments`, `-Xlinker` and `-fdiagnostics-color`.
