Hi Billa, I am not sure if compressed instruction support can be disabled, but it appears to me that --with-arch= should be rv32gc or rv64gc for multilib. It is implemented in the gcc/config.gcc file. Florian mentioned that there is no glibc without compressed instruction support. Perhaps, gcc port might also have any constraints with regard to that.
