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

Hi, Does anyone know any tool that can help generate a control/data flow graph (CDFG) for LLVM IR programs? The opt -view-cfg and related commands can visualize a program as a control flow graph. But how can I embody data flow information into that graph? Your help will be greatly appreciated! Thanks, Wenhao Jia -------------- next part -------------- An HTML attachment was scrubbed... URL:

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:

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 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 Rask, I installed the GG ls, as you suggested, and some other directory commands (rm, dir, ..) as well, into amitcp:samba/bin. BIN: is assigned to this. My path looks here first before amitcp:bin. I still get no action for mput *, with recurs on, and mask *. Also, lcd prints nothing as well. Can you suggest anything else? Am I missing something else, perhaps? Cheers, Chris. On 15 Dec 97

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

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...

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"

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, 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!

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 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

Hi Amiga Samba users, I have an interesting problem using Samba (1.9.16) on the Amiga. Everthing works fine for PC reads from the Amiga to the PC or dag-and-dropped onto Unix shares (which also using Samba). However, in the other direction (i.e. at PC GUI drag a Unix file from Unix share and drop it onto an Amiga share) this copy results in a file that my httpd on the Amiga can't read (in the

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

Hi, Yiping! I am not sure of the answer to your question, but I am forwarding it to the LLVMdev list where I am sure someone will be able to answer you. Please send development questions directly to LLVMdev and you will get a response quicker, as it is read by many LLVM developers. ----- Forwarded message from Yiping Fan <fanyp at cs.ucla.edu> ----- Date: Mon, 31 Oct 2005 17:20:24 -0800
