Registering a MachineFunctionPass
I had INITIALIZE_PASS_BEGIN and INITIALIZE_PASS_END macros. I replaced them with INITIALIZE_PASS but I get the same error. If I understand correctly, I need to modify Passes.h, InitializePasses.h, and Codegen.cpp files to register my pass, right? Another question is: Is it necessary to have the createNoopInserterPass function?

Guidelines for pass initialization?
Does anyone know what the guidelines are supposed to be for properly
initializing a pass? Looking around, we seem to have three styles of
pass registration in use.
INITIALIZE_PASS(...)
INITIALIZE_PASS_BEGIN(...)
INITIALIZE_PASS_DEPENDENCY(...)
...
INITIALIZE_PASS_END(...)
static RegisterPass<FooPass> X(...);
(This is the one encouraged in the docs, but seemingly the least widely
used in tree?)
As far as I can tell, these often appear to work interchangeably. (At
least for passes with only "well known" dependencies.) Can anyone
expose a set...

About LLVM Pass dependency
Hello
I am working on pass which has dependency on multiple passes. Say
D1,D2,D3
I used
INITIALIZE_PASS_BEGIN
INITIALIZE_PASS_DEPENDENCY(D1)
INITIALIZE_PASS_DEPENDENCY(D2)
INITIALIZE_PASS_DEPENDENCY(D3)
INITIALIZE_PASS_END.
While running it through opt tool it, I had to specify this D1,D2,D3 pass
names
to get this pass executed before my pass.
Is there way, to let llvm pass manager to know execute all dependencies
without
having to specify explicitly.?
I suspect i am doing something wrong in my code, May be.
Than...

[LLVMdev] Infinite loop when adding a new analysis pass
...icm", "Loop Invariant Code Motion", false, false)

// add this dependency
INITIALIZE_AG_DEPENDENCY(AliasAnalysis)
INITIALIZE_PASS_END(LICM, "licm", "Loop Invariant Code Motion", false, false)
Howerver, I got an infinite loop when trying
opt -O3 t.bc -o out.bc
Where t.bc is created using clang from
int main() { return 0; }
What am I missing ?

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 also give a pretty name...

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
