similar to: [LLVMdev] Simulating instruction cache misses

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 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 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);

Hello Alexandra, I have the same problem what you tell here related to the loop condition(s). You have wrote this article 3 years ago and I just want to know how do you resolve this problem. I am also thinking to keep all BBs representing a condition in a separate vector as it is done with the body's BBs (sure they will not be kept in body's list). Could you please tell your solution?

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

Hi, I'd like to ask you what's the best way of generating instruction identifiers which are consistent across independent invocations of the LLVM program. One way would be to use a counter and iterate over all the functions, then all the BBs. But are there any guarantees on the ordering of the functions and BBs in the iteration? In extremis, I can sort the functions after name, but what

I have a module having the blockaddress instruction. When I link it into another module and delete the original, blockaddress disappears and is replaced by inttoptr (i32 1 to i8*). Please compile and run the attached program to see the demo of this problem. Right after linking modules, blockaddress still exists: @switch.bbs = internal global [3 x i8*] [i8* blockaddress(@my_func,

Hi, Why isn't 'R CMD check --force-multiarch' installing the package for all the architectures that are going to be checked? For some packages, it only installs for the default arch ('i386'). Then testing the package for 'x64' fails. For example, Output of R CMD check --force-multiarch fabia_1.5.0.tar.gz: ----------------------------------------------------------- *

Hello! Yesterday I upgraded from 1.0beta3 to 1.0beta4. I've major problems now with my inbox (quite large, 900MB) and another large folder. Thunderbird 1.5 connects and disconnects. I tried to delete the indexes of dovecot and thunderbird without any sucess. Finally I downgraded to 1.0beta3 and it works well again (Beta3 was running for a timeframe from when it came out and now without

Hi, I am simulating an event that has 15 possible outcomes and I have a vector 'pout' that gives me the probability of each outcome - different outcomes have different probabilities. Does anyone know a simple way of simulating the outcome of my event? If my event had only two possible outcomes (0/1) I would pick a uniform random number between 0 and 1 and use it to choose between the two

Hi I have a pair of 1950's running as a failover pair of front ends for a Fibre array and a SCSI array. i am currently just running on the SCSI array and the fibre is not in production yet. I am seeing load on the active node sit at around 8 and throughput to the SCSI array is around 25MB/s - I would imagine i should see better figures that this and less machine load. Can anyone give
