Hi all, Can anybody tell me how to generate a mov instruction in llvm. I found out there is a MemMove Inst but I dont think that is what I want. I want to bypass a load instruction. So i need to generate a mov instruction which will help me remove the redundant load. Thanks -- Abhinav Karhu MS Computer Science Georgia Institute of Technology

Hey All, I am running into a problem with running the program using LLVM JIT. I get the following error. lli: error loading program 'Hel.bc': Bitcode stream should be a multiple of 4 bytes in length. Hel.bc is the bytecode for my simple HelloWorld program. Please give me some insight into this. Thanks -- Abhinav Karhu MS Computer Science Georgia Institute of Technology

I have compiled the program using the following option. llvm-gcc --emit-llvm Hello.c -o Hel.bc I have used llvm in the past but this sort of problem is new for me. I dont know how to go about it. Thanks for the reply. -- Abhinav Karhu MS Computer Science Georgia Institute of Technology

Hey all, I am trying to see if we can gather alias analysis information during profiling, similar to block profiling or edge profiling info which can be gathered. Is there some way that can be achieved? A pointer on this topic would be much appreciated. Thanks -- Abhinav Karhu MS Computer Science Georgia Institute of Technology

Hey all, I want to run the profile.pl file in the utils folder but I am having trouble running the script because the profile_rt.so file is not generated properly. So in order to generate that I am running make in the /runtime/libprofile. when I do that I get the following message. llvm[0]: Linking Release Lodable Module profile_rt.so llvm[0]: Compiling BasicBlockTracing.c for Release build

Hey all, I am getting this weird error which suddenly popped up today. Whenever I am trying to execute a piece of code using lli I get this following error. Error loading program 'sample.bc': Invalid bytecode signature: 464C457F (Vers=0, Pos=4) I dont know what to do..Please reply to this question. Please... -- Abhinav Karhu MS Computer Science Georgia Institute of Technology

Hey all, I compiled the code using both the -c and -S options. I can get the human readable IR but I still cannot run it using lli. The output of the IR looks like this. Can some of the information tell me about why the program is not running. ; ModuleID = 'Hel.c' target datalayout = "e-p:32:32" target endian = little target pointersize = 32 target triple =

Hi owen, Can you please elaborate as to what should I do? Find all the instruction which have r2 in it and replace all of them with r1 and then remove the load instruction?

Hi all, I am facing new problem with lli now. I am having a sample code in which I am doing malloc for two variables. If I compile the code with normal gcc the program runs without any warning of any sorts. If I compile the program to convert it into a bytecode file and then run it through lli it segfaults and the program aborts. This is the stack trace after execution. lli((anonymous
