GNU --
While the LLVM Clang compiler has been working on ARMv8.1 support since earlier this year, the developers focusing on GCC have been working on it still but the first bits have been committed to trunk this morning.

ARMv8.1 brings minor changes to the instruction set as well as to the exception model and memory translation. ARMv8 code continues to work on ARMv8.1 hardware. ARMv8.1-A adds two Adv.SIMD instructions, VQRDMLAH, and VQRDMLSH instructions, among other changes.

Hitting GCC trunk a short time ago was support for ARMv8.1, multi-lib support for ARMv8.1, patterns for the new instructions, and the new tests.
