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

...rectly, 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.

Hi, I tried passing the array directly using and changing the getorInsertFunction accordingly but this didn't work. It fails with Assertion `(i >= FTy->getNumParams() || FTy->getParamType(i) == Args[i]->getType()) && "Calling a function with a bad signature!"' failed. hookFunc = M.getOrInsertFunction("hook", Type::getVoidTy(M.getContext()),

Hi all, I am new to LLVM, and I am learning how to use LLVM for profiling. I need to pass an array to an external method, and insert a call instruction to the method in the code. After reading a few source files, I've tried using GetElementPtrInst to pass an array, but it fails at llvm::GetElementPtrInst::hasAllZeroIndices() const + 0 std::vector<Value*> Args(1);

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, 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 \

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,

Hi, I am trying to analyze the instruction cache miss rate in different basic blocks, and would like to know if there is any way to do this in LLVM. I am using the objdump file to find the size of various basic blocks and their starting address. Now, when a basic block is encountered in a BB iterator, I want to map it to one of the BBs I've collected from the dump, and use the starting
