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!

[ARM/Thumb] Make a function in arm while in Thumb triple

I tried the attributes which is used in GCC but it doesn't work.
Here is what I tried:
