+Subject: [PATCH] Darwin, aarch64 : Initial support for the self-host driver.
+
+At present, there is no special action needed for aarch64-darwin
+this just pulls in generic Darwin code.
+
+Signed-off-by: Iain Sandoe <iain@sandoe.co.uk>
+
+gcc/ChangeLog:
+
+	* config.host: Add support for aarch64-*-darwin.
+	* config/aarch64/host-aarch64-darwin.c: New file.
+	* config/aarch64/x-darwin: New file.
