similar to: [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! opt -load ../../../Debug+Asserts/lib/LLVMHello.dylib -hello < hello.bc > /dev/null My pass is just: #include "llvm/IR/Function.h" #include "llvm/Pass.h" #include "llvm/Support/raw_ostream.h" #include

Thanks! 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? -- John T. > > opt -load

Hi Weibo, I thought would be more efficient discussing here (I just saw that every info was replicated on both emails you were sending to me). I just run your example here on my working machine, and I didn't have any issues with the namespace. Just tell me one thing: which line (and flags) are you using when configuring and make your build llvm directory? Oh, and one more thing: what is on

Hi Guys, I am using the Postdom pass and I would like to get the root of the tree. However, everytime I try to get the root, I get a segfault. I don't know why the environment can't find DominatorTreeBase. Below is the code that generates the Segfault. In my .h file I include Dominators.h PDT.getRootNode(); //PDT is a reference to a PostDominatorTree dyld: lazy symbol binding

I have a dataframe such like the following: ID TIME DV 1 0 0.880146038 1 1 0.88669051 1 3 0.610784702 1 5 0.756046666 2 0 0.456263368 2 1 0.369991537 2 3 0.508798346 2 5 0.441037014 3 0 0.854905349 3 1 0.960457553 3 3 0.609434409 3 5 0.655006334 . . . . . . I would like to generate another column with the normalized values of DV. for each ID, normalize to the value at TIME 0. I was able to

Hi there, I'm currently writing an analysis (for now) pass for LLVM that kind of need some information from the CallGraph of the program. This info would be extremely easy to get if I could build the DominatorTree information about the CallGraph. I even checked out and saw the declarations of GraphTraits templates for CallGraph and CallGraphNode, which might indicate that all algorithms that

Hello, I'm trying to improve SimpleInliner to use information given by __builtin_expect instruction (It would be better to not to inline if a call instruction is unlikely to be executed). The problem here is that it is not possible to compute control dependency relationship between the annotated branch instruction and callsites using PostDominatorTree, because PostDominatorTree is a function

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

That is what I don't understand. This symbol is defined in Dominators.h, which I include in my file. I don't understand why I am getting this error. Here is my opt command, "opt -load LLVMMyDomPass.dylib -mdp < test.bc > test.d.bc" George On Tue, Aug 21, 2012 at 3:25 AM, Duncan Sands <baldrick at free.fr> wrote: > Hi George, > > ... > > dyld: lazy

I am creating a new pass (function pass) called Dfl from the Hello example and notes on "Writing an LLVM Pass". When I compile the program I get inncomplete type error (llvm/include/llvm/Pass.h:188: error: incomplete type 'llvm::DominatorTree' used in nested name specifier). The code is given below. Surinder struct Dfl : public FunctionPass { raw_ostream *Out; static

Hi, I am running into the same issue with a module pass, that calls LoopInfo.(does not call DominatorTree) I am using RegisterPass, since it is a dynamically loaded module(as per lib/Transforms/Hello) It does seem possible from the discussion, to use LoopInfo inside a ModulePass. I am wondering what the fix to this problem was. Also, the code works in 2.7.(I did not try 2.8) Thanks, Arushi

Hi all, I am implementing a new pass for LLVM which extends Call Graph SCCPass. I need DominatorTree Information when I get to individual function. I have added AU.addrequired<DominatorTree>() and AU.addRequired<DominanceFrontier>() in getAnalysisUsage() function. But, when I get to the pass, Pass Manager gives following runtime error Unable to schedule 'Dominator Tree

Hi Fellows, I am writing a pass that requires the DominatorTree pass. In the runOnFunction of my own pass, I call llvm::SplitBlock to split a block (%for.end) at it's first insert point. Then, when I dump my dominator tree immediately after, I can see the newly split %for.end.split, but its DFSNumIn and DFSNumOut are not properly updated in llvm::SplitBlock (i.e., still the initialized

I suggest you build LLVM with assertions enabled - then you should get a helpful error message rather than a segfault. I think you are not allowed to

Hi Andrew, Thanks a lot. But the function "DT->dominate(A,B)" decides the dominance relationship through comparing the DFS numbers, right? At least, in my example, when I check whether the newly split node (i.e., % *for.end.split*) DOMINATES the original node (I.e., %for.end), the answer is true, which is obviously wrong.

Hi folks, For the past month I’ve been working on improving the DominatorTree and PostDominatorTree in LLVM. The RFC that explains the motivations and plans can be found here: http://lists.llvm.org/pipermail/llvm-dev/2017-June/114045.html . Here’s a short summary of what changed upstream since posting it: - We switched from the Simple Lengauer-Tarjan algorithm for computing dominators

OT!!!!! I'm trying to learn to use audio cleanup tools from clickrepair.net. they're written in Java and distributed as .jar files. I'm having trouble running them, due, I'm sure, largely to my ignorance. I have icedtea installed, but it just errors out when I try to use it to run any of the jar files: Fatal: Read Error: Could not read or parse the JNLP file. You can try to
