     * Generic 32-bit unary operation.  Provide an "instr" line that
     * specifies an instruction that performs "result = op a0".
     * This could be a MIPS instruction or a function call.
     *
     * for: int-to-float, float-to-int
     *
     * On entry:
     *     a0 = target dalvik register address
     *     a1 = src dalvik register address
     *
     * IMPORTANT: you may specify "chkzero" or "preinstr" but not both.
