similar to: [LLVMdev] Error while compiling .cpp

Thanks a lot for replying. I would check my system gcc configuration. I got very useful replies from dev list regarding my earlier question but yet not able to determine block size. That I want in total size of a block in a function in bytes and not just the number of instructions.LLVM Tool gives most of the information e.g function bytes etc....but not individual block. Thanks Tanu Chris

Thanks for the reply. I wish to compile without optimizations ( the option being turned off ) but still generate bytecode file. Options -S , -c removes optimizations but I also need .bc file to experiment and use further. How should I do it?

Passing "-Wa,-disable-opt -Wl,-disable-opt" will disable *all* cleanup and optimizations

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 ?

Hello, I am trying to rum my pass (.cpp file) and I am getting the following error. ---------------------------------------------------------------------------------------------------------------- g++: /usr/lib/gcc/i386-redhat-linux/3.4.2/../../../crti.o: No such file or directory g++: /usr/lib/gcc/i386-redhat-linux/3.4.2/crtbeginS.o: No such file or directory g++:

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:

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.

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? -----------------------------------------------------------------------------------------------------

Thanks a lot for replying...but I am not doing any deleting or removing node ...I am trying to insert a "new" entry node in an existing list. In another reply I understood (also mentioned on the site) that no other block can branch to the entry block. How do I achieve this ? Is it feasible?Let me know if there is any example. Thanks again, Tanu Chris Lattner <sabre at

Can you explain a little bit more about what you mean by "randomize" functions or global variables? What aspect of them do you want to randomize? Their address? Their value? Something else? Reid.

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

Thanks for replying, Yes, I think too that the bytecode file is corrupted. This is the file : -------------------------------------------------------------------------------------------------------------------------

I would try that ..Thanks Another thing that I want to do is to randomize functions within a program (or file ), whatever is easier to do in llvm .Also please tell me how can I randomize global variables ?

Thanks for the reply :-) I am actually looking for ways to determine "size" of code segment when the program is in native code. Any suggestions to do that ?

Thanks for the reply, Actually I m aiming towards determining two values: - number of basic blocks in a program For this I have used Statistic facility provided in llvm and increasing the counter for each basic block for each function.but for some reason , I m getting different number everytime !! Is Statistic is the right way to do it ? - Average basic block size in a program ( in bytes)
