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

Dear all, while trying to build llvm with shared libraries using GCC (tested both in Ubuntu 14.04 and Ubuntu 16.04) as in cmake -G Ninja -DBUILD_SHARED_LIBS=ON I run into the following link error lib/Transforms/IPO/CMakeFiles/LLVMipo.dir/PartialInlining.cpp.o: In function `llvm::ForwardDominanceFrontierBase<llvm::BasicBlock>::ForwardDominanceFrontierBase()':

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 Guys, I saw in the API that DominanceFrontier has been deprecated. Is this for real? I have read the computational issues but shouldn't that be left to the users of llvm? My concern is I am writing a Control Dependence module that uses Dominance-Frontier information. Getting rid of Dominance Frontiers will put me in a tight spot.

Joshua, David much appreciate your quick help! What I am actually doing is statically tracing values. If one of the traced values is part of a condition (e.g. in an if statement) all instructions in the then and else part are also traced. The automatic tracing of instructions however needs to stop when I hit the first instruction after the if statement (same for switch). Dominators seem to be a

Hi, I found that LLVM 3.1 says Dominance frontier is deprecated. Can anyone please tell me, if there is any replacement for Dominance frontier & Postdominance frontier in LLVM? What are the options if we need to use them? Thanks, Swarup. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Yes and no. There's isn't a control dependence pass in LLVM

Hello, I have a 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

Thank you John. Actually the opt tool (from LLVM 3.2 version) can generate the needed graphs (with pass "-domfrontier"). But I just want to surely know is there some pass or builder which can be integrated somehow so it will be possible directly to generate CDG? -- View this message in context: http://llvm.1065342.n5.nabble.com/Control-Dependence-Graph-builder-tp56687p56689.html Sent
