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 a new member in the group, have been doing some experiments with LLVM IR. I am facing issue with de-compiling the following instruction once it is read, %var2 = call i8 @myfuncCall (i2 %var1) In after I parse the file (lets say using parseIRFiles ). I can see the instructions,( the function call instruction ), How can I get the %var2 from the instruction/callInstruction ? going

I tried debugging it and the issue seems to be in the implementation of MachineInstrIterator.h and the way it interacts with GraphWriter.h functions. I found this by replacing the ( template <> struct GraphTraits<MCDFGraph<MachineFunction*> >) with a similar MCDFGraph based template of CFG similar to the one in MachineFunction.h (similarly replacing the DOTGraphTraits with the

Hi, I am a newbie in LLVM. I am very impressed with this forum and appreciate your help and time. I am trying to include llvm IR parser in my codebase, the way I wanna do is generate llvm's shared object (.so) file and use it in my project. So far I haven't been able to generate correct .so's. When I build a debug build with gmake (have llvm and clang in my sandbox), I get the

Edwin, thank you for your effort, but I'm not sure I understand. Are you describing a graph traversal problem? Is the data model stored in a predecessor/successor fashion, which requires you to 'walk' the graph in order to visit all nodes? (and what happens when you have disjointed DFGs?). inline comments follow... Török Edwin wrote: > On 2009-09-06 17:30, Ioannis Nousias

Hi, I am trying to generate the DFG of machine functions. Initially, I added a pass to generate the DFG of LLVM IR functions. This was based on the mail thread - http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-September/025582.html. This pass worked fine and I was able to generate DFG of LLVM IR functions. Later, I ported the DFG pass code for machine functions. I ported the InstIterator.h

Hello, I'm going to need something like a DFG of a loop. I've been studying the ScalarEvolution analysis and it performs many of the functions I need (it's something like a DFG, going recursively backwards), but I need something that indicates me when a instruction has to be before another, or can be switched. As I said in a previously message, my idea is to match the instructions

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

Dear professor John Criswell I would like to implement a new instruction scheduling algorithm so that I need the Data flow graph(DFG) is input of the algorithm.

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, I want to know few things: 1) is LLVM IR (obtained from -emit-llvm option) an in-memory CFG? Say, I have hello.c and I generate bit-code using: clang -O3 -emit-llvm hello.c -c -o hello.bc Next, I redirect this bit code to opt: opt -load ../../Release+Asserts/lib/Hello.so -hello < hello.bc > /dev/null I have attached a example.tar.gz with one simple iterator.cpp and output from

Hi Venu, FWIW, I have a pass that does copy propagation after RA [1] (currently only within a basic block) that should be enabled some time in the not-too-distant future. It has been reviewed and accepted, but I'm currently working on getting a slight change to the MachineOperand representation [2] that should make the copy propagation change much simpler. I believe this change to

Hi, I am interested in bringing LLVM IR parser to my project. how can I do it ? What .so/.a to build and copy to my project and what are the header files I must copy over to my project area. Also how can I build the .so/.a which I need. Appreciate your guidance on this. Thank you in advance. regards tarique -------------- next part -------------- An HTML attachment was scrubbed... URL:
