Does gcc-arm-none-eabi-6-2017-q2-update-win32 support Cortex-A53 ?

Hello guys!

    We are planning to choose a CPU with Cortex-A53. Our project of C language now working on Cortex®-M7, currently we using "gcc-arm-none-eabi-6-2017-q2-update-win32" to build our C project.

    From my searching, Cortex-A53 is released in 2011, and GCC 4.8 series tool chain has support this:https://gcc.gnu.org/gcc-4.8/changes.html.

    And in the "gcc-arm-none-eabi-6-2017-q2-update-win32" Downloading page(6-2017-q2-update), It shows Features:All GCC 6 features.

    Is that mean:  Cortex-A53 is supported in this tool chain?

    

    Can you guys tell me the answer, thanks a lot!
