Hi I have question that is why don't use clang ? I think 4k is use gcc 4.2 continue and 24k and 74k to change to clang because of FreeBSD other arch move it. I want use MIPS16 instruction because it make small binary. Current build is almost 4Mbyte. If use MIPS16 instruction we get more space at 4M flash. But gcc 4.2 and binutil not correctsupport . I hope clang support correct MIPS16 instruction.
