Already did.
clang++ -ccc-gcc-name arm-none-linux-gnueabi-g++ -ccc-host-triple
thumbv7m-none-gnueabi testReference.cpp -c -mcpu=cortex-m3
fatal error: error in backend: CPU: 'cortex-m3' does not support ARM
mode execution!

...t is using the wrong ISA.
I can't understand why, but it uses armv5te instead of thumb2.

Try -ccc-gcc-name arm-none-linux-gnueabi-g++ -ccc-host-triple
thumbv7m-none-linux-gnueabi
Sometimes it's better than sysroot, as it finds it
