GCC support for cortex-a55

Question

Can someone please let me know which version of GCC onwards has the support for cortex-a55 as the mtune/mcpu option?

Below is the link mentioning the support has been added, however am unable to correlate which is the exact GNU version this support had been added first. Link for the commit below:-

Try to map to a version like this for eg:- gcc-linaro-aarch64-linux-gnu-4.9-2014.06-02_linux

Thanks in advance.

GCC 8.1 is the first release that added support for it. It's in the release notes https://gcc.gnu.org/gcc-8/changes.html#aarch64
