+# Shared settings for the AArch64 bare metal ports, the counterpart of
+# arm-none-eabi.cmake beside it. The two differ by more than the tool prefix:
+# AArch64 has no -marm or -mthumb to choose between, no -mfloat-abi, and
+# aarch64-none-elf-gcc rejects -mlong-calls outright, so that flag cannot simply
+# be carried across.
+#
+# The tools are named without a path, so an aarch64-none-elf toolchain must be
+# on PATH. Override CMAKE_C_COMPILER and friends on the command line to use one
+# that is not.
