Hello, guys. I am trying to construct higher-level 'for' from the low-level LLVM bitcode(ver 1.9). It's partly successful thanks to David A. Greene's advice suggested to use Control Dependence Graph(CDG). I could find which BB contributes to form which loop with CDG. For example, for this simple function: ----------------------------------------------------------- void bsloop(int n, int pM, Params* ps) { int i, sim; for (sim=0; sim < pM; sim++) { for (i = 0; i < n; i++) {...

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 from the LLVM - Dev mailing list archive at Nabble.com.

Hello, I tried to install package ?TailRank? using the command install.packages (RankTail) and library (TailRank) but I got the following errors. So, how can I install TaiRank in Rstudio to have se beta-binomial distribution, CDF and inverse CDG of beta-binomal?

...ot. > > George Hi, I had the same issue implementing a pass that build PDGs for an exam two months ago. As an alternative to the (post)-dominance frontier method I used the algorithm described in [1], section 9.5 "Program Dependence Graph" where you can find a method to build the CDG using only the post-dominator tree.

Yes and no. There's isn't a control dependence pass in LLVM per se, but I believe that is primarily because control dependence is very easy to compute with the existing analysis passes in LLVM. With PostDominanceFrontier, it was extremely simple (I think it was calling two methods i...

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.

Hello All, I am interested in Control Dependence Graph building using the CFG and Dominance Frontier provided by corresponding passes.

I have a little niggling situation that I would like to resolve programmatically. I use Git as my SCM and I have release branches which are sometimes patched. I find myself sometimes entering the working directory tree forgetting that I was last on a release branch and not on the master. What I would like to do is to have a script run every time that I enter a directory, check for .git, and if
