[LLVMdev] loadable passes with dependencies?
I still have the addRequired:
virtual void getAnalysisUsage(AnalysisUsage &AU) const {
AU.addRequired<DominatorTree>();
}
The other line
DominatorTree *dt = &getAnalysis<DominatorTree>();
Is for later use when I try to use PromoteMemToReg

[LLVMdev] loadable passes with dependencies?
Just shows me what I expect
void getAnalysisUsage(AnalysisUsage &AU) const {
DominatorTree *dt = &getAnalysis<DominatorTree>();
So I'm only using it for DominatorTree(so I can use PromoteMemToReg).
Thanks

Awesome, that let me get far enough to trip:
Assertion failed: (ResultPass && "Unable to find requested analysis
info"), function getAnalysisID
Is there something else I forgot?

Something's different here, earlier in the thread you said you had:
void getAnalysisUsage(AnalysisUsage &AU) const {
AU.addRequired<DominatorTree>();
}
Now you have:
void getAnalysisUsage(AnalysisUsage &AU) const {
DominatorTree *dt = &getAnalysis<DominatorTree>();
I'm sort of confused, why did this change happen? I think the

[LLVMdev] Using Function Passes from Module Passes
Dear All,
I'm having some problems using a function pass from a Module pass. My
code is as follows:
DominatorTree & domTree;
...
Function &F = *I; // I is an interator from using Module::begin()
...
domTree = getAnalysis<DominatorTree>(F);
When I compile this code, I get the following error:

[LLVMdev] DominatorTrees, DominanceFrontiers, interfaces and cloning
...transform that, given a function F, will produce a new
function G such that the basic blocks of G are (copies of) a subset of
the basic blocks of F, and such that control flow is connected as you
would expect. Given DominatorTree and DominanceFrontier of F, I would
also like to efficiently compute DominatorTrees and DominanceFrontiers
of G. I understand how to do this mathematically, but I'm having some
problems with the llvm codebase.
I have two questions:
(1) Is there any way to clone a DominatorTree or DominanceFrontier
object, so that I can modify the cloned copy? It looks like Pass

[LLVMdev] Runtime exception in DominatorTree.getRootNode()
Thanks for your reply, John.
I am using opt to run my pass. Should opt by default link in the library?
Would you please give me some idea on fixing it? Thanks!

My pass is just:

[LLVMdev] Basic doubt related to Module::iterator
Hi,
Yeah I found that it is running LLVM's functions. The functions that are
running are:
main
llvm.dbg.func.start
llvm.dbg.stoppoint
scanf
llvm.dbg.region.end
But I dont want all the functions to be called as I am using Dominator
Trees and whenever I the statement
DominatorTree &DT = getAnalysis<DominatorTree>(F);
is encountered by functions other than main, it gives error.

[LLVMdev] 2.9 segfault when requesting for both LoopInfo and DominatorTree analyses.
When migrating my project to 2.9, I've encountered a strange segfault
where if a ModulePass's getAnalysisUsage adds LoopInfo and
DominatorTree, then llvm::PMTopLevelManager::findAnalysisUsage will
segfault. What's odd is that if I rearrange this (add required for
DominatorTree before LoopInfo), it does not segfault. I realize that
LoopInfo requires and preserves DominatorTree, but this

Odd. I would think that opt would have that pass linked in statically.
I'm not sure why it's not working. Does anyone else have an idea?

Hi Surinder,
Did you remember to #include "llvm/Analysis/Dominators.h"?
Best,

[LLVMdev] Runtime exception in DominatorTree.getRootNode()
Hi all,
I am trying to traverse a dominator tree and have encountered a weird
runtime exception:
Here's my simple code:
virtual bool runOnFunction(Function &F) {
DominatorTree& DT = getAnalysis<DominatorTree>();
* DomTreeNode* rootNode = DT.getRootNode();*
return false.
}

[LLVMdev] Pass Incompatibility
I have a transformation where I'd like to use both DominatorTree (for ExtractCodeRegion), and DemoteRegisterToMemory (i.e., reg2mem). The transformation is phased, so all occurrences of getAnalysis<DominatorTree>(Function) happen before any occurrence of getAnalysisID<FunctionPass>(&DemoteRegisterToMemoryID, Function).
If I register these two passes with DominatorTree first, I

[LLVMdev] getAnalysis*() called on an analysis that was not " "'required' by pass!
Hello,
I'd appreciate it if anyone can tell me what the error message means and
point out what I am doing wrong.
Thank you.
I am trying to use the result of the DominatorTree analysis in my ModulePass
class as explained in the section "Writing an LLVM Pass".
http://llvm.org/docs/WritingAnLLVMPass.html#interaction
I called the method "addRequired<DominatorTree>()"
