[LLVMdev] LLVM instrumentation
...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.

[LLVMdev] SFI and Artificial Diversity
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

[LLVMdev] BNF for IL/IR interpreter
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

[LLVMdev] LLVM instrumentation
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,

[LLVMdev] Code-generation: lang=>JSON, JSON=>lang and merging into lang
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.

CFLAndersAliasAnalysis print implementation
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
