What is the Strict Aliasing Rule and Why do we care?

(OR Type Punning, Undefined Behavior and Alignment, Oh My!)

What is strict aliasing? First we will describe what is aliasing and then we can learn what being strict about it means.

In C and C++ aliasing has to do with what expression types we are allowed to access stored values through. In both C and C++ the standard specifies which expression types are allowed to alias which types. The compiler and optimizer are allowed to assume we follow the aliasing rules strictly, hence the term strict aliasing rule. If we attempt to access a value using a type not allowed it is classified as undefined behavior(UB). Once we have undefined behavior all bets are off, the results of our program are no longer reliable.

Unfortunately with strict aliasing violations, we will often obtain the results we expect, leaving the possibility the a future version of a compiler with a new optimization will break code we th

#前言 由于大家都懂的, 国内使用go get的时候, 经常会各种失败, 如果有vpn的话, 打开vpn, 问题就解决了, 但vpn其实挺不灵活的.

相对来说shadowsock则灵活得多.

#解决方案 shadowsock + Privoxy

思路就是, 使用shadowsock建立一个本地sock5代理, 但因为go get 需要http代理, 所以需要使用privoxy把sock5代理转为http代理.
