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

zb l 17 days ago

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!

The easiest way is to invoke the compiler with the specific -mcpu=cortex-A53 argument from the command line:

$ arm-none-eabi-gcc -mcpu=cortex-A53
arm-none-eabi-gcc: fatal error: no input files
compilation terminated.
$

If the Cortex-A53 isn't support, than GCC should about an error message like this (Here tried with none-existent Cortex-A89 as an example):

$ arm-none-eabi-gcc -mcpu=cortex-A89
arm-none-eabi-gcc: error: unrecognized -mcpu target: cortex-a89
