不变代码外提(Loop Invariant Code Motion)是一种重要的循环优化,其目标就是自动的发掘不变的代码,并把这部分计算提到外面,于是不用在循环里重复计算。有的同学可能会问,写代码的时候,直接手动把循环里面的重复计算都提出来不就行了吗?其实这样也不是不可以,但是所有时候都手动这样操作,一方面可能会造成编程的负担...
循环不变式外提(Loop Invariant Code Motion) 张键盘 爱好广泛,十八般武艺,略懂略懂。 来自专栏 · 编译原理和编译优化 5 人赞同了该文章 在编译优化中,主要的优化可以说都是跟循环有关,因为循环的执行次数比较多,如果减少一条冗余语句,因为执行的次数够多,那么效果也会很好。下面我们就来讲这个优化。
循环优化中的一个重要方法是循环不变代码外提（Loop Invariant Code Motion），其目标是自动发现循环中的不变代码，并将其移出循环，从而避免重复计算。尽管手动提取循环内的重复计算代码是一种可行的方法，但在所有情况下都这样做可能会增加编程负担并影响代码可读性，同时也可能导致创建额外的变量。编译器...
However, in the context of deep learning applications, the traditional loop invariant code motion algorithm has severe limitations. Firstly, it's difficult to determine the extra-benefit of moving certain invariant code out of loops. Secondly, it's difficult to detect l...

Code motion based optimizations are used quite often in electronic design automation (EDA) tools to improve the quality of synthesis results. Ensuring the correctness of such transformation is necessary for reliability of EDA tools. A value propagation (VP) based equivalence checking method of finite...
Finding these objects and moving them out of loops requires sophisticated interprocedural analysis, a task that is difficult for traditional dataflow analyses such as loop-invariant code motion to accomplish. Our work targets data structures that are loop-invariant, and presents a static type and ...
6.1. Pendulum Motion on a Circle in the Phase Plane A pendulum with velocity proportional linear friction, as well as a nonlinear restoring sine-type force shall be described by the following state equations: 𝑥˙1𝑥˙2=𝑥2=−sin(𝑥1)−𝑥2+𝑢,x˙1=x2x˙2=−sin(x1)−x...
