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?

hey, There is tool that calculates execution count and total number of blocks , is there anything available to detemine size of basic blocks in a program in bytes?

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 ? Thanks Tanu Chris Lattner <sabre at nondot.org> wrote: On Mon, 25 Apr 2005,

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

This is exactly what i m trying : opt -load /home/tsharma/ankur/llvm/Debug/lib/LLVMHello.so -hello <helloprog.bc> /dev/null Tanu Chris Lattner <sabre at nondot.org> wrote: On Wed, 9 Mar 2005, Tanu Sharma wrote: > I wrote a pass which randomizes basic blocks and insert new block.But > when i run another pass over it which simply lists all basic blocks I > don't get

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

The entry block, by definition, is the first basic

Thanks for replying . I came across another problem while trying it. The following compilation is not working: ( with the native option) llvmgcc x.c -o a.out -Wl,-native I get this error: gccld: a.out.s: Can't destroy file: ut.s How can I fix that ?

This bug has been fixed in CVS, please update your

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 ?

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 a lot for replying. I have another query. If branching to the entry block is not legal in llvm how should I be able to create a new entry block for any existing list? I created a new block and inserted it into the present basic block list , but I get this error: opt: BasicBlock.cpp:83: virtual llvm::BasicBlock::~BasicBlock(): Assertion `getParent() == 0 && "BasicBlock

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.
