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, 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

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, I have read the steps of code generation from here: The LLVM Target-Independent Code Generator — LLVM 3.8 documentation |   | |   | |   |   |   |   |   | | The LLVM Target-Independent Code Generator — LLVM 3...Instruction Selection Instruction Selection is the process of translating LLVM code presented to thecode generator into target-specific machine instructions. | | | | View on llvm.org

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);

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

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

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, I know clang supports -pthread option (here). Does this mean I can call pthread routines inside llvm code and which pthread library is used, the one for Linux OS or the one for Windows?

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®

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

Hi, some custom CPU models are reported from virConnectGetDomainCapabilities as usable='yes' on a physical machine while as usable='no' inside a VM running on the same machine. That's not completely surprising. But what surprises me is that those models are still reported from virConnectCompareCPU as supported (VIR_CPU_COMPARE_SUPERSET) in the nested environment and VMs can

Hello, I have a pre-production Intel Skylake server using dual 8176 processors (28 core @2.1Ghz) I have loaded from the DVD distribution CentOS 7.3 and RHEL 7.4 with no problems. When I try and load CentOS 6.9 the boot process hangs just as the Anaconda graphics is started for CentOS configuration. If I use a secondary graphics card then the process completes with no problems and CentOS boots

I upgraded from 7.3 to 7.4 over the weekend.? Everything went well except that I can't login because the screen is black with a cursor. If reboot boot the 7.3 kernel 3.10.0-514.26.2.el7.x86_64 kernel everything works just fine, so my guess is that there's a kernel issue with the hardware, specifically the Skylake processor. Has anyone else run into this problem and if so can how I
