Is compiler language support common to all compiler ports

  arm-none-eabi-gcc, c++, libstdc++

I’m using GNU Arm Embedded Toolchain 10-2020-q4-major (arm-none-eabi-* 10.2.1) and I would like to take advantage of modern c++ features.

So I’m trying to find out which c++ features (language core features as well as libstdc++ features) are available with this particular toolchain. I read through this matrix https://gcc.gnu.org/projects/cxx-status.html, and they don’t seem to distinguish between different compiler ports.

How could I find if I could use C++17 or C++20 features for example ?

Hugo
