會自我學習的程序編譯器

剛剛在Slashdot上看到一個新聞，IBM今天發佈全球首個開源的Machine Leaning Compiler,叫Milepost GCC, 官方網是http://www.milepost.eu/

這個程序編譯器的最大特點可以自我學習，在編譯代碼時可以對程序進行分析，並找到最適合的優化方法編譯程序。試驗表明，用這個編譯器編譯程序的運行效率可以提高18%.

開源之後的項目還會繼續研究這個領域，不斷的提高編譯器的分析能力。

Milepost官網上的介紹 寫道

The overall objective of this project is to develop compiler technology that can automatically learn how to best optimise programs for re-configurable heterogeneous embedded processors. If successful we will be able to dramatically reduce the time to market of re-configurable systems. Rather than developing a specialised compiler by hand for each configuration, our project will produce optimising compilers automatically. Current handcrafted approaches to compiler development are no longer sustainable. With each generation of re-configurable architecture, the compiler development time increases and the performance improvement achieved decreases. As high performance embedded systems move from application specific ASICs to programmable heterogeneous processors, this problem is becoming critical.

This project explores an emerging alternative approach where we use machine-learning techniques, developed in the artificial intelligence arena, to learn how to generate compilers automatically. Such an approach, if successful, will have a dramatic impact on re-configurable systems. This means that for a fixed amount of design time. We can evaluate many more configurations leading to better and more cost-effective performance. If successful, this will enable Europe to increase its dominance in this critical emerging market.

 
感覺特好玩，還是頭次聽說有這樣的編譯器。做一下記錄，留着有空時試一試看。
