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...
计算循环不变式 如果A=B + C,B和C的定义点都在循环外,那么A也就是不变式.也不是所有的循环不变式都可以移动出去,这个必须要domain所有的循环出口.对于循环不变式,满足一定的条件,那么我们是可以做code motion,提出循环外面的。 loop规约化 对于,正常的while do格式,我们要统一做个转换,变成do-while格式。为什么...
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...
Loop invariant code motion optimization pass completely breaks my shader. Output SPIR-V is valid, but when ran it actually crashes driver. What we're doing is optimize SPIR-V with spvtools::Optimizer, then pass it to spirv-cross and gene...
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...

t is a generalizR(Iz of standard loop-invariance code motion, but based on loop quasi-invariance analysis. Loop quasiinvariance is similar to standard loop-invariance but allows for a finite number of iterations before computations in a loop become invariant. n this paper we define the notion ...

Loop invariant code motion moves instructions that are loop invariant, i.e. instructions that always yields the same result in each iteration of the loop, outside of the loop. This decreases the amount of work that needs to be done in the loop, and consequentially, increases performance. ...
