The Radeon GCN compiler back-end was merged months ago for GCC 9 as the work being done by CodeSourcery / Mentor Graphics under contract for AMD. That code is already being used within the company's CodeBench Lite AMD software and with time is expected to become useful in its own right within GCC.

This firmware update/change was needed since the existing signed firmware files weren't working correctly on newer Pascal graphics cards.
