similar to: LLVM and Pthreads

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

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

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

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);

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

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. Thank you,Iulia -------------- next part -------------- An HTML attachment was scrubbed... URL:

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

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®

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

Hi all, I would want to know if from the runOnFunction method of a Function pass, other functions in IR, except for the one received as parameter, can be obtained as well, from a call instruction, as follows: Function F = dyn_cast<Function>(callInst); Or do I need a Module pass to work in IR with multiple functions from input source code? If so, it is accepted to have O(n^3) complexity in a

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

Hello, I am building LLVM with ninja on Linux environment and I continue to have the error below. I am thinking that the cause might be my PC not having sufficient RAM memory. In this sense, I extended my swap memory with a swap file (90GB), but it didn't solved the problem. Should I add more physical RAM memory to my PC, or is there any software based solution I can try first? Thank you and

Is there any support for x86_64 pthreads for mini-OS ? Does the current newlib contains a functional implementation of pthreads ? -- Karim Allah Ahmed.

Try llvmgcc pthread.c -o pthread.ll -pthread You have to link in the pthreads library, and I believe -pthread is all you need on a redhat 9 box.

I have done some reading and gather than wine-pthread was dropped somewhere around 1.1.19. Problem I have is that I have an application (newsleecher) which effectively never starts up (gave it 10 minutes at one point, used 100% cpu the whole time) with strait wine command on the older wine version, I think 1.0.something, came with ubuntu 8.04 in one of the unsupported repositories. It starts up
