Hello everyone

I'm intending to port Qt to SK8855 processor whose tool chain is ARC GCC (http://www.arc.com/software/linux/). The command is "./configure -embedded arm". I meet a build break which is something like "bad instruction: swpb". It seems that there is no swpb instruction in the instruction set of the MCU.

My question is whether it is possible to port Qt to ARC processors. What can I do if the process doesn't support swpb?

Thanks,
Jim King
