similar to: [LLVMdev] Control Data Flow Graph (CDFG)

Hi John, My project is somewhat inbetween, but closer to the latter. If you are doing something related to synthesis, have you checked xPilot from UCLA? Search "llvm" in this paper <http://www.icims.csl.uiuc.edu/~dchen/xpilot-TechCon2005.pdf> Anyway, thanks for the information! :-) Wenhao On Tue, Mar 3, 2009 at 6:30 AM, <llvmdev-request at cs.uiuc.edu> wrote: > >

Unless someone else responds with "I've already done that" then you need to implement a pass. It's probably something you want to customize to your needs anyway. -Andy On Jun 30, 2011, at 11:50 PM, janarbek wrote: > Hi Andrew, > Thanks for the response.

Hi Andrew, Thanks for the response. That helps a lot. So that means I have to implement a pass, right ? Sorry for dumb question. I just started LLVM today.   =========================================== Phone : 82-42-860-1838 Fax : 82-42-860-6790 Cell Phone: 82-10-7599-1981 =========================================== --- On Thu, 6/30/11, Andrew Trick <atrick at apple.com> wrote:

Hi All, I am reposting my question again since i think my question was not clear enough. I am wondering is it possible to generate Control Data Flow Graph from C using LLVM? or is it possible to get web-like structure of C code using llvm / Thanks in advance, Any comment suggestion would be appreciated.

Hi All, I am wondering if there is anyone who is working on generating Control/Data Flow Graph generation from C code ?  Can anyone point me where I should look in order to generate CDFG ? I am planning to develop one for myself. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, Does anyone know if there is any existing code I can use to do a loop-carried dependence analysis for LLVM IR programs? I searched the mailing-list archive and it seems like someone planned to implement a loop dependence analysis pass in March. I'm just wondering if this project is ongoing/finished or if there is other projects that may have the code I'm interested in. Thanks!

Hi, Your attempt didn't work because you didn't do what I suggested, which was make sure that your data frame matched the example given in the help for gantt.chart. Here's what you have: > str(cdfg) 'data.frame': 3 obs. of 3 variables: $ c1d1: Factor w/ 3 levels "task 1","task 3",..: 1 3 2 $ c2d1: POSIXct, format: "2018-04-01"

Hi All, I am new to LLVM. I want to generate a Dataflow graph or Control Dataflow graph from C code using LLVM. I have no idea how to do it in LLVM. I tried to use analysis and transform passes such as "-dot-cfg" but it doesn't give what I want. I want to generate a node for each operation in C code.  Thanks in advance.JM. -------------- next part -------------- An HTML attachment

We have built a tool which will take in a CDFG (in a particular format) and do some design automation based on it. The effort is to extend this tool to take an input from in the form of a systemC (extension of C++) code. The IR was used to generate the CDFG of the source code. But the requirement is to generate the CDFG of only a specific function and hence I am looking to iterate over the member

Hi Sarah Thank you very much for your pointers. Is there a way to specify the date string as POSIXct when reading in? I have tried the following (very inelegant way) and still have no luck. --- Begin Code --- # 1st read in the spreadsheet with stringsAsFactors set to FALSE > abc <- read.csv("gntr1.csv", header=TRUE, stringsAsFactors=FALSE) > abc code tasks.labels

Hello, I used optim to find the MLE estimates of some parameters. See the code below. It works for data1(x). but It did not work for data2 and the error says" L-BFGS-B needs finite values of 'fn' ". data2: c(x, 32) that is, if I added the number 32 at the end of data1. The error appears "non-finite function value" etc. Any comments or suggestions? Thanks!

Hi everyone, I'm adding loop profiling to LLVM built-in profiler. I'm just wondering in a class that's not a pass, such as ProfileInfoLoader, how can I get information produced by passes such as LoopInfo and DominatorTree? In other words, ProfileInfoLoader is not a pass, so it can't call AnalysisUsage::addRequired and AnalysisUsage::getAnalysisUsage directly. Then how can it know

It looks like this problem only exists on nested loops, ideas?

Is it not a good idea to try and extract loops that have multiple exits?

Has anyone seen this error before? I'm trying to load a pass that apparently isn't registered, it's just the "Hello World" sample , so I don't see the problem. Error: me at here:~/llvm/llvm_core/llvm-2.9$ opt -load Release/lib/LLVMHello.so -hello <cdfg.c> /dev/null Error opening 'Release/lib/LLVMHello.so': Release/lib/LLVMHello.so: undefined symbol:

Hi, is there a way to dump control flow graph dot file only for a specific function name? -dot-cfg option for opt command seems to dump cfg dot files for all functions. -ananth  -------------- next part -------------- An HTML attachment was scrubbed...
