Let CallGraphSCCPass Use Function-Level Analysis
Hi Mikhail,
As Brian noted, stuff like this works better in the new pass manager.
Even in the old pass manager I thought it should work though.
Did you initialize the pass, via
`INITIALIZE_PASS_DEPENDENCY(PostDominatorTreeWrapperPass)`?
Did you require it, via
` AU.addRequired<PostDominatorTreeWrapperPass>();`?
Btw. May I ask what you are planning to do?
Cheers,
Johannes

Error: Verify if there is a pass dependency cycle
Hi,
You need to initialize your pass with:
INITIALIZE_PASS_BEGIN(YourPass, "your-pass", "Your Pass",
/*cfgonly=*/false, /*analysis=*/false)
INITIALIZE_PASS_DEPENDENCY(PostDominatorTreeWrapperPass)
INITIALIZE_PASS_END(YourPass, "your-pass", "Your Pass", /*cfgonly=*/false,
/*analysis=*/false)
So as to both register your pass, and have PostDominatorTreeWrapperPass
(which is the Analysis pass in charge of creating the PostDominatorTree)
initialized before your pass.
It als...

Error: Verify if there is a pass dependency cycle
Hi everyone,
I write a new FunctionPass which wants to use pass PostDominatorTree, so I
implement the next function:
void getAnalysisUsage(AnalysisUsage &AU) const {
AU.addRequired<PostDominatorTree>();
AU.setPreservesAll();
}
Then I get PDT through the next statement:
PostDominatorTree *PDT = &getAnalysis<PostDominatorTree>();
My code can be successfully

Let CallGraphSCCPass Use Function-Level Analysis
Dear all,
I would like to use the PostDominatorTree in ArgPromotion. I did not find an example of how to use function level analysis inside CallGraphSCCPass. I tried to follow an example of how to use function-level pass in a module pass, but I hit "llvm_unreachable" in PMDataManager::addLowerLevelRequiredPass.
What would be a proper way to make PostDominatorTree available in
