similar to: [LLVMdev] simple question:basic blocks avg size

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)

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?

Hello, I have been trying to randomize the basic blocks of a program in memory and disk , keeping the control flow intact. Is there any easy way provided in llvm to achieve that? any other suggestions? Thanks Tanu __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

The entry block, by definition, is the first basic

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 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?

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 !! 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 ?

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

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

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

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 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 ?

I have a doubt. This is an excerpt of the raw report I get after running Spec benchmarks through llvm-test.I am trying to calculate the program execution time.Does the output result in bold corresponds to "lli time" in Makefile.spec ? I am not interested in llc, jit or cbe.I simply need the normal bytecode and native code execution times after running my pass over them.I have modified

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 : -------------------------------------------------------------------------------------------------------------------------

Hello, I have been trying to compile the SPEC benchmark but have failed even after several attempts.The first error I get while trying to run is : -------------------------------------------------------------------- Error loading program '../00000002/gzip_base.x86_linux.bc': Can't open file: ../00000002/gzip_base.x86_linux.bc
