similar to: LLVM IR from static/dynamic libraries

Hi, Is decompilation possible in general to the SSA form for binaries? I assume one has to make certain assumptions about code in general to get tools like these to work. For example if code like with dlsym or jit heap allocated functions can be incorporated at runtime it would seem that in general it is quite difficult to ascertain the boundaries of a basic block and insert the correct phi

Hi, I am newbie for LLVM. I need some help, I want to disassemble ARM binaries and perform some operation on LLVM IR and again back to generate ARM binary from modified ARM LLVM IR. How I can proceed for the same. Any tool or document will be highly appreciated. Thanks and Regards, Deep -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi Herbie, thanks for you answer and explanation. > > Also, if any of the functions are external, you are completely stuck (unless you put everything together with lld). I am indeed having a problem regarding external function. I my program is just one file everything work and I can access all the functions. However, if it has multiple files I have a lot of unresolved pointers to

Thanks for your response. In your experience, was it worth the conversion hassle and code expansion to have the code in a platform-independent SSA form and be able to apply LLVM-based analysis tools? Or is it better to convert to another IR (such as BAP[1]) and work in that form? Bob [1] Binary Analysis Platform, http://bap.ece.cmu.edu/ --- On Thu, 6/10/10, Nathan Jeffords <blunted2night at

Hi guys, I am compiling some programs with clang which use a couple of libraries. When I compile with the command - "clang -O2 -I. -o hello -ldl -llttng-ust hello.c tp.c", it goes successful. My aim is to get the bitcode for these programs but if I try to generate the bitcode with -emit-llvm option, it produces linking issues as follows : (also at - http://pastebin.com/zkmL2SAH)

This might be a very beginner question, but I'm looking for an example for something that I have never done. Suppose that I wanted to express actions with respect to lifted semantics of CPU instructions to an intermediate representation, BAP IL or LLVM IR. How might I go about providing a Backus Naur Form specification and then dynamically interpreting those lifted instructions by also

Thank you so much for the reply, Tim ! I have some follow up questions (in the inline replies), it would be great if you can answer those.

This may be a dumb question, but here goes So I''m running on Puppet 3.1.1 on RHEL5, and i''ve been using Hiera since 2.5/2.6 ish and it''s been great!! I was reading up on Automatic Parameter Lookups and would love to use it for my modules. But I can''t seem to ever get Hiera/Puppet to load the value i''ve set in my yaml files. I feel like I must be

I want to transform elf binary to llvm IR, and do some instrumentation based on llvm. Is there any tool which can do the transformation?

Hi I was wondering if there is any way we can run whole program analysis on more than just one compilation unit. I would like to include the dynamically loaded libraries into the call graph too. Is there a way to do that? Thanks and Regards Rohit -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi guys, I am following this[1] tutorial to install clang. However, I have made a small change in the configure command, and I am running it with '--enable-optimized' option to avoid the debug build. I am getting the errors (given at the end) related to *undeclared identifiers '__NR_*'*. Can someone please provide some input about how to tackle this issue? On my other machine, I

Dear All, I am following a flow to generate object files(.o) from input (.s assembly) files. The input .s is given to AsmParser, which creates MCInst after matching instruction opcode. These MCInst are converted to MCStream and then finally emitting to an object file using Target Code Emitter. I am considering whether hazard recognition can be done on the list of MCInst, which I get after

Hi, I am curious to know about LLVM IR as platform independent feature. I have compiler some C and C++ applications that compiled on Linux 64bit machine, now I want to generate bit code file on Windows 64bit machine. 1) Will this execute without any issues? 2) Do I pass any option for making it operating system portable? 3) Can I generate bit code file also on Linux machine and then run on
