By searching for information about clang，I find the option of loop analysis caps is “WidenLoops”. But I can not find the “WidenLoops” in the source code of clang.
If you know the location of the “WidenLoops” in the source code of clang, can you tell me?
Thank you very much!
Is it the "ShouldWidenLoop" (static analyzer) option you are looking for?

It has been renamed from "WidenLoops" in
https://github.com/llvm/llvm-project/commit/549f9cd46f912a1b9e49fa88e348496fe9299382
Alternatively, there is a "WidenIV":
