similar to: [LLVMdev] Fwd: bytecode file

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:

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

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 :

OOps.. I overlooked :-) Thanks Tanu Misha Brukman <brukman at uiuc.edu> wrote: On Wed, Mar 09, 2005 at 12:18:33PM -0800, Tanu Sharma wrote: > This is exactly what i m trying : > > opt -load /home/tsharma/ankur/llvm/Debug/lib/LLVMHello.so -hello /dev/null Well, you're not saving the output of your pass, it's going to /dev/null.

I have trouble using the llvm tools.Some of the errors are : $ llvm-dis prog.bc $ llvm-dis: Invalid Top Level Block Length! Type:1, Size:456 (Vers=0, Pos=12) ------------------------------------- $ extract -o=outprog prog.bc $ extract: bytecode didn't read correctly. Where am I doing wrong ?I wish to get human readable form of my bytecode file.The tool giving similar error. Thanks Tanu

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

Type:1, Size:456 (Vers=0, Pos=12) Can you explain how you generated this bytecode file? It looks corrupted or something. Also, can you send the actual bytecode file itself? Thanks! -Chris >

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 ?

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

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 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

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?

Compile it with llvm to a native .o or .exe file, then run 'size' on it? E.g.: llvm-gcc x.c -o a.out -Wl,-native size ./a.out -Chris > Chris Lattner <sabre
