代码中提示 fp_mode=relaxed to enableTMU hardware support for FP division

TI工程师您好，有个疑问，代码中以感叹号形式提示如下内容是什么原因，请指教：fp_mode=relaxed to enableTMU hardware support for FP division？

Susan Yang：关于 fp_mode 您可以参考下

Relaxed mode prioritizes speed over strict correctness. In relaxed mode, the compiler may perform speed optimizations at the expense of reducing the precision of some calculations, typically a tiny amount. For instance, (X/3) is not precisely equivalent to (X*(1.0/3)), but in relaxed mode, the compiler is allowed to make this transformation anyway, as multiplication is much faster than division.

在Relaxed 模式下优先考虑速度而不是严格的正确性，编译器可以执行速度优化，但代价是降低某些计算的精度，不过通常都是很小的量。
