I guess you mean madd and mul (not mulu).
These instructions are MIPS32 instructions and are most likely not recognized
by your toolchain.
Try use the compiler option "-mips32" to verify it.
So for now I'm afraid you need to hardcode these by hand. We are very close to
release a MIPS32 compiler, so we don't need these hacks in the future.
