PickVidsC++Now 2018: Matt Godbolt “What Else Has My Compiler Done For Me Lately?”
推荐理由
Both are great presentations going into details on some of the crazy optimizations compilers will do.
说明
这是2018年由CppNow发布的一部演讲，主题归在Compilers, interpreters & program analysis。它讲的是compiler optimizations这一支里的具体问题，而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成：Matt Godbolt, creator of Compiler Explorer, tours surprising optimizations modern compilers perform, such as turning loops into closed-form sums and using popcount instructions. He explores what the compiler does behind the scenes.这些读者给出的理由，核心是：HN recommends it as a detailed, entertaining look at the crazy optimizations compilers do.讲法不绑某一条新闻，过几年仍然可以当材料看。从2018年到2020年，有3位不同的读者在3个不同月份把它推荐出来，其中明确叫别人去看的有1次。适合一次性看完。讲者把一个判断讲透，演示是在给这个判断配例子。如果已经会了基本定义，就把注意力放在它怎么把compiler optimizations变成能跟着复述的例子。
