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 scr...

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" "2018-04-15" ... $ c3d1: POSIXct, format: "2018-04-15" "2018-05-31" ... Here's what you sh...

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.

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 ?

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 func...

Hi, I am new to LLVM and am trying to identify all the member functions of a class. Currently, I am converting the source code into the IR using a llvm frontend. I have written a module-pass which will take in the IR thus generated and iterate over the various types (classes/structs) defined in the source. For every such type, I will iterate over the sub-types (types of its members). I was

Sir ,how can I get the variable %2 in instruction %2 = sub nsw i32 1, %y If I am using getName() function then it outputs the null string. How can I get the original name?

Hi, The help file for gantt.chart states that dates must be in POSIXct format, and the example shows how to do that. There's no reason that I can see that you can't use a data frame as input to gantt.chart, but you need to be very careful that your data frame matches the correct format. I bet also that your character fields were imported as factors, because you didn't specify not to.
