Compile application for Ariane

[AnouarNechi]

Hello
the new toolchain is a little bit confusing sorry.
If I want to compile c code to run with on Ariane core knowing that I might use floaiting point in the code. which option should I use to build the toolchain. is this ok:
./configure --prefix=/opt/riscv --with-arch=rv32imc --with-cmodel=medlow --enable-multilib make
or I should use:
./configure --prefix=/opt/riscv --with-arch=rv64g --with-cmodel=medlow --enable-multilib

Thank you

You should look at the riscv-manual. There is a section that describes what those extensions mean. For ariane you probably want rv64gc.
