Hi Tim, My mistake not including the llvm-dev, excuse me. affinityElement.__bits[0] worked fine for me, thank you. I am new in using the API for Constants and I am facing the error "incomplete type is not allowed" on the last last of below code: Type * ET = IntegerType::getInt64Ty(I.getContext()); unsigned long size = cpuAffinityVector.size(); ArrayType * AT = ArrayType::get(ET,size);

Hello, Could someone please tell me why LLVM and clang downloaded from here: svn co http://llvm.org/svn/llvm-project/llvm/trunk llvmsvn co http://llvm.org/svn/llvm-project/cfe/trunk clang and generated using cmake: cmake -G "Visual Studio 15 2017" ../llvm does not compile in Visual Studio? I am using Batch Build in Visual Studio and I have selected only ALL_BUILD project to build as

Thank you. So the ABI in llvm will be "gnu" for all Linux distributions?

Iulia, You need to check the contents of the hello.ll (or hello.bc) file rather than the input *.c file - ultimately that's what opt consumes. Try compiling without any optimisations: clang -O0 -emit-llvm -S hello.c -c -o hello.ll -Andrzej On 18/09/2019 11:34, iulia_s24 wrote: > Hi, > > Actually I copy-pasted step 5 from the article in which I found the > solution, in the text

Can you also please tell me how can I find out the ABI (application binary interface)?

Hello all, I would like to obtain a constant that is initialized with a value of type cpu_set_t, a type which is defined by Pthreads. The problem is that a variable of this type cannot be cast to an int value, even in C source code. I tried get methods from Constant or ConstantInt classes, but with no result. How can I obtain such constant object in IR? Thank you, Iulia -------------- next

Hi, Could you please confirm the following steps for debugging a pass? 1. copy your pass into llvm/lib/Transforms/Hello/Hello.cpp 2. name you pass Hello 3. insert debug messages like:     errs() << "Vis­iting func­tion " << F.get­Name(); 4. get LLVM bitcode:    clang -O3 -emit-llvm hello.c -c -o hello.bc5. disassemble the bitcode:     llvm-dis hel­lo.bc 6. run the pass on

I want to cross-compile using clang and I have to specify the following triple: <arch><sub>-<vendor>-<sys>-<abi>I know that sub-architectures ("sub" in the triple) for x86_64 Intel Xeon processors could be v2 for ivy bridge or v3 for haswell or v4 etc. Could you please answer: which version of sub-architecture is considered sandy bridge for Intel® Xeon®

Hi, I know LLVM provides thread-level automatic parallel support using OpenMP (see  http://blog.llvm.org/2015/05/openmp-support_22.html), but it is not clear for me which of the following is correct? 1. Clang inserts in the source code OpenMP compiler directives, so, it auto-parallelizes the serial source code provided as input or2. Clang can compile manually written parallel source code that uses

Hello, 1. Can you please tell me how can I find the type of my Intel Xeon?I see in LLVM code that Intel Xeon processors can be of type "core2", "penryn", "westmere", "skylake". 2. I also see that "skylake" can be a type and a subtype as well.How can I find out the subtype of my architecture? Looking forward for you answer. Thank you.Iulia On

Hello, Could someone please answer the following question: Does LLVM support code generation for Intel Processors? Which Intel processors are supported? I am interested especially in Intel Xeon Processor, but you can give me information about the others as well.

Hi all, I want to find memory dependency between CallInst instruction and other. So i used the following code: * AliasAnalysis &AA=getAnalysis<AliasAnalysis>();* * if(isa<StoreInst>(inst1)){* * ** **if(isa<CallInst>(inst2))**{* * CallInst *call_inst2= dyn_cast<CallInst>(inst2); * * if(AA.getModRefInfo(inst1,call_inst2)==mod)**{* *

1. If we run a few passes in a sequence ..is the bytecode file transformed after each pass in sequence i.e if we have a) opt -pass1 -pass2 -pass3 < in.bc > out.bc b)opt -pass1 -pass2 < in.bc > tmp.bc opt -pass3 < tmp.bc > out.bc are the above two equivalent ? what I basically want is to run my pass on an optimised bytecode , so should i optimize it and get a new bytecode

Hi all， Im trying to instrument this hello function right before the instruction that call the "puts" function(the source code is as follow). Now I can compile the pass without errors, but when run the pass with opt tool, it broke down. The diagnose is something like Referencing function in another module! %CallCheck = call i32 @fib() Broken module found, compilation aborted! Does

Hi all, Sorry for the inconvenient about the previous post. The files were not attached. So I put them here again. I am a newbie in LLVM and I am trying to replace the function like: old function || new function ============================== ========= int haha(int a) { int haha(int a, char* ID) { ===> }

Hi all, I wrote a function pass. In the pass, it ran through all the instruction that call to functions. When arriving at the exact function that I m interested in, it would insert a self-made function. Now I've finished the pass, the compilation is successful. The pass can find the function I like and can insert the CallInst to call my check function. BUT, when running the

Hello, I hope you are all doing well and thanks in advance. I need to program a transformation of a set of llvm bitcode to have some various techniques woven in. In particular, I need to resolve a given computed target address to one of several in the same way that the function of a dynamic library is resolved, but I need this resolution to happen in the binary target of my choice where I tell
