Hi, I am trying to optimize some benchmarks using LLVM and run them on gem5 simulator (build for ARM). I am using Sourcery Codebench cross-compiler for ARM on my x-86 machine. My steps up till now have been using the following commands. 1. clang -static -emit-llvm -march=armv7-a -mfloat-abi=soft -target arm-elf a.cpp -c -integrated-as \

Thanks Renato and Giang. I was able to run a simple HelloWorld program on gem5 (in SE mode) by using -target -arm-none-linux-gnueabi as the option during cross compilation. I am trying to cross compile some Computer Vision algorithms, which use OpenCV libraries, and I tried using the same command line options - clang++ *-emit-llvm -static -c -Wall -g -O0 -mfpu=vfp -mfloat-abi=soft

Hi Silky, If I got correctly, you seem to be trying to run a bare-metal image on your model, but you compile with linux-gnueabi GCC. I don't know if that will make a difference, but I'd try to use none-eabi GCC toolchain and set the -target armv7a-none-eabi just in case.

Though it may be little older, it will work I think. You can look at the code to see how we do the instrumentation.

Oh, OK. I didn't check the code. I think it only contains your flow tracking analysis code, isn't it. Our 'Giri' project was completely separate from it. Should we merge it with this or keep it as a separate project? -Swarup. ________________________________________ From: John Criswell [criswell at illinois.edu] Sent: Tuesday, January 22, 2013 12:12 PM To: Sahoo, Swarup Kumar Cc:

Hi John and Silky, I can see a copy of 'giri' slicing project branch here http://llvm.org/viewvc/llvm-project/giri/. Though it may be little older, it will work I think. You can look at the code to see how we do the instrumentation. Thanks, Swarup. ________________________________________ From: John Criswell [criswell at illinois.edu] Sent: Tuesday, January 22, 2013 10:29 AM To:

Hi, I am new to LLVM, and would like to write a dynamic profiler, say which prints out the load address of all the load instructions encountered in a program. >From what I could pick up, edge-profiler.cpp increments a counter dynamically which is somehow dumped onto llvmprof.out by profile.pl Could anyone explain me how this works? Can I instrument the code to dump out the load addresses or

Hi, @Alastair: Thanks a bunch for explaining this so well. I was able to write a simple profiler, and run it. I need to profile the code for branches (branch mis predicts simulation), load/store instructions (for cache hits/miss rate), and a couple of other things and therefore, would need to instrument the code. However, I would like to know if writing the output to a file would increase the

Hi Alastair, Thank you so much for the information on the tools. Actually, I need to analyze which sections of code are prone to misses and mis predicts, and would have to eventually instrument the code. I was able to instrument and call an external function, but faced an issue while passing an argument to the function. I am following EdgeProfiling.cpp but couldn't figure out the problem.

Hi Silky, Sorry for the slow reply. You probably already fixed this, but just in case I'll reply anyway.

There is code that does this for older versions of LLVM. I believe it is in the giri project in the LLVM SVN repository. I can look into more details when I get back from vacation. Swarup may also be able to provide information on the giri code. -- John T. ________________________________________ From: llvmdev-bounces at cs.uiuc.edu [llvmdev-bounces at cs.uiuc.edu] on behalf of Silky Arora

dear Sir, i am running red hat 6.2 on one machine and windows 95 on another but i am unable to see the linux machine in my windows pcs network neighborhood.to check my samba server i tried the tests given in DIAGNOSIS.txt.I am able to run tests 1 to 4 without error but in test 5 which says ::: "test 5 : run the command "nmblookup -B ACLIENT '*'" You Should Get The

Me again.... After getting regular playlist streaming working, I'm not trying to complete the project and implement the live streaming. Unfortunately, due to the sad, lacking documentation for icecast and ices (especially what the xml tags in the configuration files actually DO and how they can be used), I've run into another snag that only you guys can help me out with. Here it goes.

Hi, I am working on Instruction prefetching, and wish to pre-fetch (insert intrinsic prefetch instruction) basic blocks based long before the branch operation is seen. I was thinking if there is any way of extracting the values used in the compare instruction, and going to there definition to speculate on the taken branch. I would like to know if I can extract the values from the instruction,

Silky, feel free to add your error messages to that bug to make sure it's taken into account when fixed. cheers, --renato -------------- next part

Dear Sir, when i give the command "nmblookup -d 2 '*'" IP addresses of not all PCs in the network are shown only some of them are shown.And so if i try to access the Linux machine from the computer which is not shown its not accessing Linux Machine moreover it is not even showing it in the network neighbourhood of that machine but when i telnet from Windows Machine to
