The experimental results show that, automatic compiler tuning can get better performance than the manual tuning in the training cases and in the new cases, they get close performance.

实验数据表明，基于机器学习的编译自动调优技术对已知实例能得到比手工调优更好的性能，而对未知实例的预测能力也能达到跟手工调优接近的水平。

From that, the protocol buffer compiler creates a class that implements automatic encoding and parsing of the protocol buffer data with an efficient binary format.

protocol buffer编译器据此创建一个实现自动编码的类并且以一种高效的二进制格式来分析protocol buffer数据。

For automatic vectorization or scalarization, the compiler USES versions of the MASS functions contained in the compiler library libxlopt.a.

对于自动化的标量或者向量，汇编器会使用汇编器库libxlopt . a中包含的mass函数的版本。
