Thanks a lot for replying Chris, I m trying to randomize the blocks in a program.I generate a random number( between the current "InsertPos" and the last block), and then iterate through the list of basicblocks , picking up block with position equal to that of the random number and place it into the current InsertPos and increment InsertPos. Running it like this:

Hi, I have been trying to randomize blocks in a program and modified "BasicBlockPlacement.cpp" for the purpose but getting segmentation fault.I am not able to determine the problem.Can anyone please decrypt these error messages or suggest what might be the possible cause of failure? -----------------------------------------------------------------------------------------------------

Ms Brukman, Thanks for your reply.Just clarifying my question.I actually wanted to randomize the static layout of function code in the executable file.Sorry for writing in confusing manner.

How would you "randomize the order of calls made to functions when a program is run" without changing the semantics of the

LLVM does not need to construct a CFG, because the CFG is an explicit integral part of the program representation. Every BasicBlock ends

This has been listed as an "open project" for a long time [1], but someone already implemented it, saving us the time and effort. Thanks for the link! [1]

Hello, I have been trying to compile spec benchmark with llvm.I am trying the 2 methods suggested but have not succeeded yet . 1) Setting the flags -Wl,-native-cbe or -Wl,-native flags to llvm-gcc. This results in successful compilation with llvm BUT it doesn't create .bc files (?)which I need for my experimentation.Any other significant modification/addition missing ?? 2) Using llvm-test :

By randomization of functions I mean the manner in whch they are called , so that has to do with address.I wish to randomize the order of calls made to functions when a program is run.

Thanks a lot Chris. Regarding basic block size I wish to calculate both: - The number of bytecode bytes - The number of machine code bytes for some target?

Tanu, You've seen ? :- http://www.st.cs.uni-sb.de/~lindig/src/quest/ Don't know whether it is applicable to what you are trying to achieve but I thought I should point it out in case it is useful to you and you have not seen it.

Thanks !! But if i generate a .bc file like this and then run my pass over it like this : opt -load /home/llvm-cvs/llvm/Debug/lib/LLVMHello.so -hello <helloprog.bc> class_prog.bc Will the new .bc file (class_prog.bc) be also without optimizations ?opt also does some optimizations.Can I control them ?

I am currently playing around with llvm using Visual C++ Express (beta). It works flawlessly. It takes a while to get started but once you do, everything is perfect. Make sure to get the latest CVS sources, the 1.4 release doesn't play nice with Visual Studio. Once you do, extract the file I attach to this email into the llvm\win32 folder. Then add llvm/win32\tools folder to a list of
