I consulted with a MIPS expert about this.  It seems that the .cpload
directive is only supported by the MIPS32 instruction set, not the
MIPS16.  Really what should happen is that you get an error message
saying "unrecognised opcode" or some such.  What actually happens when
you run into this problem ?
