similar to: [LLVMdev] Segmentation fault 'cause of accessing function arguments

Hi all, I am experimenting to run a pass inherited from CallGraphSCCPass. In the pass, I iterate all functions in a SCC. In each iteration, I access all arguments of a function in the following way: Function::arg_iterator PI = fun->arg_begin(), PE = fun->arg_end(); ... I have no trouble with building. However, I am troubled with "segmentation fault" when I run the pass

Quick question. How important are these? Are the errors recoverable and not a big deal, or are they actually a problem? I see a few of these randomly over the course of the day.

Hi everyone, I am wondering what is the right way to register an alias analysis pass. My alias analysis pass is implemented in a dynamic load module. As I can see, a general way to register a pass looks like: llvm::RegisterPass<Analyzer> X("rci", "RCI Pass"); However, registering a type-based analysis uses: INITIALIZE_AG_PASS(...) I think, registering an

I've landed the patch in r324449. Before we merge this into two different Clang release branches and almost immediately release one of them, I would really like someone to confirm that this patch works well with the Linux kernel. David, if you're up for that, it would be great. Alternatively, Guenter or someone else here can help. On Tue, Feb 6, 2018 at 5:59 PM Chandler Carruth

Windows98, Emacs20.7, ESS5.1.18 I recently constructing a data.frame "belle" that now does not spew its contents when I type the name on the command line (see errors below). It will only do so if I specify columns. Incidently, plot(belle) displays the pairs plot of all variables. > belle Error in as.data.frame.default(x[[i]], optional = TRUE) : can't coerce array into a

I am running R 1.2.3 with ESS5.1.18 with Windows 98. I am trying to use lsoda in the odesolve apckage and am having problems. Question: The return value of the function of the system of ode's has to be a list that includes first, the ode's and second, "a vector (possibly with a `names' attribute) of global values that are required at each point in `times'." I

Hi, I am working on a pass to convert lib calls to intrinsic calls as discussed here: http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-January/058507.html In my first attempt I created a FunctionPass that uses CallInst::setCalledFunction to replace the callee with the appropriate intrinsic (using Intrinsic::getDeclaration). After the pass runs I get an assertion from CallGraphSCCPass:

(windows 98, R 1.2.3, ESS 5.1.18, nlme 3.1 from CRAN) Dear R users, I am trying to follow Pinheiro and Bates book ("Mixed-Effects Models in S and S-PLUS"). I downloaded the nlme package from CRAN, and unzipped all the data and help files. Unfortunately, I cannot generate the figures in the book. For instance, their appears to be no plot.design or intervals plotting functions. Have these

I have been trying to write my own user defined function in Rpart.I imitated the anova splitting rule which is given as an example.In the work I am doing ,I am calculating the concentration index(ci) ,which is in between -1 and +1.So my deviance is given by abs(ci)*(1-abs(ci)).Now when I run rpart incorporating this user defined function i get the following error message: Error in

Hi, I am writing a CallGraphSCCPass that uses LoopInfo which is a FunctionPass. However, doing so results in the following error. **** Unable to schedule 'Natural Loop Information' required by '......' **** Google led me to this page, where Devang Patel suggests implementing the addLowerLevelRequiredPasses in CGPassManager in a manner similar to MPPassManager.

Hi, I'm working on the iterated register coalescing graph coloring allocator and try to test it with all backends available currently in LLVM. Initial tests with most of the backends are successful. It turned out that my allocator triggers a specific assertion in the RegScavenger and only for the ARM target. It looks like the LR register is used for frame pointer related things, but it is

Sorry to resurrect an old thread, but I finally got around to testing this approach (round tripping through bitcode in memory) and it works beautifully - and isn't that much slower than cloning. I have noticed however that the copy process isn't thread-safe. The problem is that in Function, there is lazy initialization code for arguments: void CheckLazyArguments() const { if

If I run: opt -globals-aa -die -inline -debug-pass=Details foo.ll -S then I will get this pass structure: Target Library Information Target Transform Information Target Pass Configuration Assumption Cache Tracker Profile summary info ModulePass Manager CallGraph Construction Globals Alias Analysis FunctionPass Manager BasicBlockPass Manager Dead Instruction

I added a new column using a migration. Once I updated the new.html.erb, edit.html.erb, show.html.erb, and the index.html.erb I brought up my web pages. There was a field to update show. I tried the update and the it was successful but the update did not show up in any of the other pages. What did I miss? I am using 2.3.3 of ror.

I''m having a problem but don''t know what is causing it so I don''t know exactly where to post, please bear with me. I''m trying to set up https access however whenever I go to https://url_for_site the root route renders but the url is rewritten to http://url_for_site. The ssl request shows in the apache logs but obviously no further ssl requests show up.

So I got very mixed results. With the CallGraphSCCPass, both `addRequired<DominatorTreeWrapperPass>` and `addRequired<MemoryDependenceAnalysis>` fail at runtime. The LLVM core has just two CallGraphSCCPasses and neither uses neither analyses, so it's hard to find a valid example. I transformed the pass into a ModulePass, using scc_iterator as shown in CGPassManager to process

Hi, I'm trying to use CallGraphSCCPass, but I keep getting a bus error. I can reproduce the problem quite easily using the lib/Transforms/Hello example. I simply mix in these changes: #include "llvm/CallGraphSCCPass.h" ... struct Hello : public CallGraphSCCPass { static char ID; // Pass identification, replacement for typeid Hello() : CallGraphSCCPass(&ID) {}

Hi all: I've included below a brief description of coroutine related optimization passes and some questions/thoughts related to them. Looking forward to your feedback, comments and questions. Thank you! Roadmap: ======== 1) Get agreement on coroutine representation and overall direction. .. repeat 1) until happy http://lists.llvm.org/pipermail/llvm-dev/2016-June/100838.html (Initial)
