Thanks  Kryzstof, I will look at it. Is there any class that I should look at it ? What about Dataflow.h ? Since I am kind of new, I want to know which classes can help me quicker.    =========================================== Phone : 82-42-860-1838 Fax : 82-42-860-6790 Cell Phone: 82-10-7599-1981 =========================================== --- On Sat, 11/3/12, Krzysztof Parzyszek

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 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 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, I commited several patches today that implement a framework that enables data-flow optimizations on the post-RA (post-SSA) representation. I thought I'd say a few words about what it is. The code is currently under lib/Target/Hexagon, but there intent for it from the beginning was to be target-independent. The motivation for it came from our (Hexagon) experience with customer

Hi, if you change unlink to ::unlink on that line, does it help? Ciao, Duncan.

You should be running the "patch -p0 < unistd.txt" in the root LLVM source directory for the trunk version. If you're still getting "Hunk #1 FAILED at 51." errors, you're not doing
