    Hi there, i'm trying to use **getAnalysis()** method to get some information about domtree or loops, and i tried to write a pass following the llvm15 document, it's works by use “ **AM.getResult<HelloAnalysis>(F)**; ”，inside the template is an analysis pass which returns a std::string.

In my opinion, DomTree and LoopInfo are also **analysis** passes, so they should work too. when i try to use "auto &DT = **getAnalysis<DominatorTree>()**;", or "**LoopInfo &LI = getAnalysis<LoopInfoWrapperPass>().getLoopInfo()**;", which worked fine in a pass i written some month ago by runOnModule(by set getAnalysisUsage,and include the head of these modules). but when i use it in my pass written by new pass manager, the compiler complain like below:
"HelloWorldUse.cpp:62:16: **error: ‘getAnalysis’ was not declared in this scope**
     auto &DT = getAnalysis<DominatorTree>();"
and
"**error: expected primary-expression before ‘>’ token**
     auto &DT = getAnalysis<DominatorTree>();"
now i am so confused to the new pass manager and how to use getAnalysis() to use other pass's data or method in a **FunctionPass**
. By the way, i also want to know how to get a FunctionPass's data or method in another FunctionPass.
any answer or link will be appreciated, thank you for help!
