...remember correctly, pintool does not work on ARM (or quite bad). My goal with the instrumentation is, once I have the information (time + call), to choose (during a second compilation) if some of my passes are applicable or not.

Actually I figured out that it is: opt -cfl-anders-aa *.ll But now I noticed that I need the graph that it computes, and it doesn't seem to emit that.

I read a lot of white papers, but is there not any open source implementation of SFI or artificial diversity? I google around, but I can't find anywhere anything regarding what I could openly download. In the same respect, I would also like to make an innovation proposal to create such an endeavor if there is not one already. -------------- next part -------------- An HTML attachment was

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

Hi everyone, I would like to instrument my code in order to know the number of times a function is called and its execution time. After some research, I find several leads in llvm/lib/ProfilData/ and llvm/lib/Transform/Instrumentation/ but nothing conclusive. Does anyone know if this is already possible with LLVM or has a good suggestion for the beginning? I saw the -fprofile-instr-generate,

...g/doxygen/classllvm_1_1Instruction.html Alternatively, you can use the dump() operation to dump the instructions out. Unfortunately I don't know how to address your second question. That's stretching my knowledge in LLVM.

Possibly protobuf or capn proto would be much more clean alternatives to json. I was working with interpreting instruction semantics a while back, and you shouldn't have to write a parser to get the data structure back into coherent form, you can get what you want automatically and have the structure isolated into a common schema.

Thank you so much! What about discovering the instruction pointer value? Also, does anybody know how to embed an artifact as a resource in a binary? I'd like to have two text sections, and have one copied in from another binary.

Is there a particular way to run a specific alias analysis that is already implemented on a .ll file produced by clang -S -emit-llvm?

Hello all, I'm having trouble getting this analysis to print out it's graph of aliases. I am processing an example C file into llvm ir, like this: int main(void) { int x=1, y=2, z=3; int *p; int **p1, **p2; if (x==z) { //0x100000f40 p=&x; p1=&p; x*=2; *p1+=z; } } clang -S -emit-llvm example.c -o example.ll Then, I am trying to run the Andersen alias

Hello, I want to know if LLVM support static taint analysis now ? and how to implement static taint analysis code in term of LLVM pass or something else ? can anyone help me?Thank you very much! zhaoqian -------------- next part -------------- An HTML attachment was scrubbed...
