That looks like it does a preorder depth first traversal (I think). I'm looking for postorder. Is there a trivial transform between the two? (I don't know one.) Am I wrong about the preorder/postorder? If not, anything lurking for postorder traversal?

The reverse postorder iterator does what you want. It's defined in ADT/PostOrderIterator.h, and is used like this: ReversePostOrderTraversal<Function*> RPOT(&F); for (ReversePostOrderTraversal<Function*>::rpo_iterator RI = RPOT.begin(), RE = RPOT.end(); RI != RE; ++RI) <work here...

...latively confident this could be optimized more. - Seemingly significant reduction in memory reduction, still working on a robust benchmark. Suggestions for the best way to do that are welcome. - Support for applying functions with an inorder traversal (as in `stats::dendrapply`) as well as using a postorder traversal. This implementation was tested manually as well as running all the unit tests in `dendextend`, which comprises a lot of applications of `dendrapply`. The postorder traversal would be a significant new functionality to dendrapply, as it would allow for functions that use the child nod...

I'm looking for a way to traverse machine basic blocks in a specific order. Basically I want all blocks that are predecessors to the current block to be traversed before the current block. I've looked at MachineDominatorTree but this doesn't traverse them in quite the way I want them to. Anyone know of a way to do this? Thanks, Micah -------------- next part -------------- An HTML

Check out "llvm/ADT/DepthFirstIterator.h", it lets you iterate

For nefarious reasons I won't go into (this is for a quick hack that will be thrown away in a week or two), I'd like my Asm printer to get MBBs in a depth first order. Is there an existing pass or function that will let me do this easily? Thanks, Dan

Dear useRs, I am working on a project involving the clustering of a large dataset. I need to extract specific sub-clusters from the parent dendrogram for further analysis. The data is too large for the use of convenient tools such as identify.clust (it selects the specific group of interest on a graph), so alternatively I have saved the plot as a large image file so that it can be printed or

Hi, I found the -postdomfrontier pass in *llvm*.org/docs/Passes.html, but 'opt' does not accept it. I could not find the relevant codes in PostDominance.cpp in SVN trunk, but I found some relevant codes here http://opensource.apple.com/source/clang/clang-137/src/lib/Analysis/PostDominators.cpp. I am wondering why this pass is removed and what should I do if I want the post

Hi, I read your post in LLVM forum. I want to use getAnalysisUsage(AnalysisUsage &AU) to get MachineLoopInfo. I have used this on my passes before but, this time I am trying to get this information in ScheduleDAGRRList scheduler class. There is no runonmachinefunction function. Do you know how I can implement this? Regards, Fateme I will appreciate it you can help me with this problem.

Hello LLVM, Can you suggest a good way to use the loops and induction variable passes to map loop exiting BasicBlocks to InductionVariables. That is, can we use these tools to identify the loop condition.

Hello, I am currently studying Computer Science at TU Eindhoven. I am doing a course that involves programming assignments on parts of LLVM such as lowering, scheduling and optimization. For this year's Google Summer of Code I plan to submit a proposal to implement a clang-based diff tool [1]. I think it really pays off to have decent developer tools available, as they can save tons of time.
