similar to: How to debug passes

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

> opt -load lib­dum­my­pass.so -dum­my­pass hel­lo.ll Looks like you are loading a shared library different from "LLVMHello.so". did you change the name of the compilation unit from "Hello.cpp" into "dummypass.cpp"? (As asked previously by Andrzej) did you register the dummy pass? > RegisterPass<DummyPass> X("dummypass",

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?

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®

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

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

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

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, 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.

For those of us not familiar with clang internals, it would be helpful if you could describe the parts of clang that you're considering sharing and explain what existing code they would replace in flang (if any) and what benefits we gain by sharing them. In particular, these were mentioned previously: DiagnosticsEngine, SourceManager, SourceLocation, FileManager, VFS Thanks, Tim 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

Hi Paula, This error is fine. The buildbot has tested the worker version. 0.8.x apparently does not have that method. The error gets handled gracefully on the server side. At least it seems so so far. That should not prevent your bot from connecting.
