We are very pleased to announce that a new version of LLBMC is available for download at http://llbmc.org. LLBMC is a high-precision static analyzer based on LLVM implementing a technique called "Bounded Model Checking". LLBMC can detect errors such as: - Illegal memory accesses (e.g., buffer overflows) - Integer overflows - Division by zero...

LLBMC http://llbmc.org uses bounded model checking technique to find errors in LLVM IR.Model checking is essentially search, and since LLBMC is bounded, the search for errors is usuallyincomplete, hence the approach may not verify the entire program, however, it may be goodenough to find interesting erro...

Hello, all, My name is Scott Santucci and I'm a software developer kicking around various wild ideas. (I wish I had something more interesting to say about myself than that, but nothing comes to mind; my day job is in SQL and Java, nothing to do with LLVM.) I am wondering whether anyone has tried using LLVM to apply formal verification to program code. I'm thinking about trying to

Hi, We are developing a bounded model checker for C/C++ programs (http://baldur.iti.kit.edu/llbmc/) that operates on LLVM's intermediate representation. While checking a C++ program that uses STL containers we noticed that llvm-gcc and clang handle pointer differences in disagreeing ways. Consider the following C function: int f(int *p, int *q) { return q - p; } Here's the LL...

What is the best level to use for backend development? We do not need to generate machine code, but rather an intermediate representation that will give us the control flow graph. Is this the llvm IR? If so, how do I read into memory a file that was generated by clang++ -emit-llvm <source file>. Thanks, Sitvanit Sitvanit Ruah Formal Verification Group IBM Haifa Research Laboratory Tel:

...operations in our LLVM-based bounded model checker [1]. For this it is important if the trunc was on a signed or unsigned integer, so we need nsw and nuw flags for this. Would you accept a patch that adds these flags to LLVM (and possibly clang)? Regards, Florian [1] http://baldur.iti.uka.de/llbmc/
