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. } Here's the documentation page: http://llvm.org/docs/doxygen/html/classllvm_1_1DominatorTree.html And here's my runtime exception: dyld: lazy symbol binding failed: Symbol not found: __ZN4llvm17DominatorTreeBaseINS_10BasicBlockEE11getRootNodeEv Referenced from:...

Hi George, > When I compile llvm in release mode, the problem goes away! I don't understand? probably the function defined in the header is inlined into every function that calls it when optimization is turned on, but not when optimization is turned off. Ciao, Duncan.

Hello, Bug is already fixed by Chris (see: http://llvm.org/bugs/show_bug.cgi?id=4915) . I added getRootNode() == NULL condition to my patch. It's not a great solution, but it is enough for now I think. New patch attached. -Jakub -------------- next part -------------- A non-text attachment was scrubbed...

...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.

Here is an updated patch for shrink wrapping with: - spills/restores done with stack slot stores/loads - stack adjustment removed - refactoring (but still in need of more) - spill/restore insertion code unified with spill/restore placement code Documentation available here<http://wiki.github.com/jdmdj/llvm-work/shrink-wrapping-work> illustrates shrink wrapping with loops and discusses a

Hi, It looks like PDT.getRootNode() returns NULL for: define fastcc void @c974001__lengthy_calculation. 1736(%struct.FRAME.c974001* nocapture %CHAIN.185) noreturn { entry: br label %bb bb: br label %bb } Isn't it a bug in PostDominatorTree? Please note that this crashes: opt -postdomtree -debug dom_crash.bc I thin...

Many published analyses which build on post-dominance assume a canonical single-dominator-tree form induced by unifying all exits (and often adding a virtual edge from START to END). In contrast, it seems that the current LLVM post-dominator analysis only operates in a mode in which it generates a forest of post-dominator trees, with one rooted at each exit node. The problem this can cause is
