My problem was that the constructor for DenseMap has an undocumented constraint. explicit DenseMap(unsigned NumInitBuckets = 0) { init(NumInitBuckets); } if given an explicit argument, requires that the argument be a power of 2. It's checked by an assert in init(), but for some reason my code didn't trip the assertion. Is there a special way I must make to enable asserts? Thanks,

Reading the LLVM Programmer's Manual, the description of DenseSet mentions: *Note that DenseSet has the same requirements for the value type that DenseMap <http://llvm.org/docs/ProgrammersManual.html#dss_densemap> has.* But when I read about DenseMap, I don't really see any requirements for the values, just a warning about space. On the other hand, the *keys* have special

Try breaking the critical edges (-break-crit-edges). This way, a new block will be created between BB13 and BB11 (call this BB11.break) and BB15 and BB12 (call this BB12.break). The predecessors of the dominance frontier will, thus, be BB11.break, BB12.break, and BB14. When we enter through a block with a call to malloc(), we will end up in one of the blocks in the dominance frontier (kind of).

Am I missing a Package? I'm not sure why is won't read the functions.

Hi, I am trying to find out the scale efficiency and optimal scale of banks by stochastic frontier analysis given the panel data of bank. I am free to choose any model of stochastic frontier analysis. The only approach I know to work with R is to estimate a translog production function by sfa or other related function in frontier package, and then use the Ray 1998 formula to find the scale

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:

Hi Henrique, I have tried using -mergereturn and inserting a free into the predecessors of dominance frontier of malloc block and it caused double free. It is possible for multiple free's to be inserted on the path from malloc to an exit. For example, in the following CFG: BB10 (malloc) / \ BB11 BB12 ... / \ / \

In the literature (see below for a reference), when a dominance frontier is computed, it is computed from a CFG that contains a dummy entry node and dummy exit node. Further, those dummy nodes are potential members of the (post-)dominance frontier for a given basic block. In LLVM, I could not figure out a way to determine if the dummy entry node is a member of the post-dominance frontier of

I need to estimate maximum tree crown radius and am looking for a package to prepare stochastic frontier models in R. I have not found any package references on Nabble R help, google, or R help. Any tips on a package for this? With regards, Aaron Trowbridge Researcher BV Research Centre Smithers B.C. -- View this message in context:

Is there a reason this is better than the modified algorithm created by Ferrante? It looks like yours has as bad a worst case time bound in reality. That is, the algorithm runs in O(sum of the size of all the dominance frontiers). http://www.cs.rice.edu/~keith/Embed/dom.pdf See figure 5. It will only touch nodes actually in the dominance frontier. This is what GCC uses. There are actually real

I just finished upgrading our LLVM to 2.4 and I immediately ran into a problem with dominance frontier calculation: llvm/lib/VMCore/PassManager.cpp:714: void llvm::PMDataManager::verifyDomInfo(llvm::Pass&, llvm::Function&): Assertion `0 && "Invalid dominator info"' failed. Strangely enough, the Pass running when the assert triggers is Dominance Frontier

Dear all, The below has been tested quite thoroughly by now, including performance-testing by the way of using a modified compiler that triggers the below while compiling at least an old part of LLVM ["Function.cpp"] and sorting a symbol table with >7000 global variables. Unfortunately, the optimization I have been working on for which I _thought_ I needed the ability to sort a

Thanks! I will try that and see whether it works.

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.

Could anyone help me with some little problem? When I plot the frontier I get the following message: *"Error in dimnames(x) <- dn : length of 'dimnames' [1] not equal to array extent"*(see below for detail). How could I solve this.
