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 >

Hello All, Thanks for the reply.I can generate the reports by compiling Spec through llvm, but that couldn't resolve my problem. I m trying to determine execution time for the bytecode and native files , which are obtained as a result of running my pass over the original bytecode .I am running these experiments on spec benchmark. In SPEC we have command line tools such as runspec where

Hello , I am compiling SPEC 2000 benchmarks with llvm .Got stuck with calculating "execution time" of all the .bc and native files. The log for nightly test itself gives execution times but I am passing the bytecode files to my pass which gives another bytecode file.I have to calculate execution time of such bytecode and native files as well.If i simply do this: time lli

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 ?

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?

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 !! 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

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 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, 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)

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
