Linaro cross toolchain 32 bit or 64 bit?

Question

I am developing a kernel on my PC (running Linux Mint 64 bit) and want to transfer that code later onto a Raspberry Pi 3B+ running Raspbian 32 bit. Now I am confused. Do I need my IDE to pick my gcc-linaro-arm-linux-gnueabihf-raspbian-x64 in the 64 bit version because I am developing on 64 bit or do I need it to pick the gcc-linaro-arm-linux-gnueabihf-raspbian because the target is a 32 bit Raspbian?

Answer 1

After doing some research myself, I can say that the toolchain/compiler needs to fit the address system of the development platform (in my case a 64 bit PC). Nevertheless, the kernel compiles for the 32 bit target platform (in my case a 32 bit Raspbian running Raspberry Pi)...
