IQmath_fpu32.lib compatibility cannot be determined

hi: TI 的工程师你好？

我这边硬件平台是 TMSF28069     加载 的 iqmath_fpu32.lib  打开 fpu32        --opt_level off          --opt_for_speed  2    --fp_mode  strict

使用中 有几点疑问，麻烦解答一下，谢谢

1：在编译时 MATH_TYPE = FLOAT_MATH 选择浮点时没有问题， 但是在选择 MATH_TYPE = IQ_MATH 定点时就会有如下这样的 warning ，不知是怎么引起的该怎么消除，    

2：在出现上面警告时发现 计算上面的 函数的 结果是对的， 但是 计算的时间是有明显的差异的

以_IQsin为例   执行_IQsin 1万次   在MATH_TYPE = FLOAT_MATH 时需要 9.06-1.326 = 7.734ms    在MATH_TYPE = IQ_MATH 时需要 7.160-1.326 = 5.834ms

请问这时我的 IQmath_fpu32.lib  使用的是否有问题

3：在上面的情况下我发现    做 float*float   的时间 几乎 和 long*long的时间  所以 我想请问 在浮点计算时 TI 是否也提供了 对这样 的 _IQsin 等 复杂函数的运算库， 具体要怎么做？  在  motoware 里 的 2806xRevB_FastSpinROMSymbols_fpu32.lib 是干什么用的 添加进工程后，  在工程的.cmd  文件里要修改吗？

    ERIC:

    这个是编译器兼容性问题，不会影响实际效果，可以直接忽略。
