I'm not sure what you mean by "move gcc", and what is this "completely
different architecture"? The best answers depend on what you mean.

Have you created your own CPU with its own instruction set? Then you
want to "port" GCC (and binutils for the assembler and linker) to your
architecture. That's quite a lot of work. You could start by reading
https://gcc.gnu.org/onlinedocs/gccint/Back-End.html and
https://wiki.osdev.org/Porting_GCC_to_your_OS
