similar to: [LLVMdev] new at LLVM

Hi, I’d like to propose adding a new example directory (llvm/examples/IRTransforms) as a new home for example code used by various tutorials. After talking to a few people at the Developers meeting, it became clear to me that it would be valuable to have the code examples for various tutorials in-tree to keep them from bit-rotting and make it very easy to build them. I’d suggest adding new IR

Hi Dan, Thank you for your advice on the build/install.

What is the preferred method for compiler (frontend) developers to optimize and generate target machine code from IR? At one point I found a tutorial that recommended simply dumping the IR to a file and spawning llc to do the job. Up until now I have "manually" created a TargetMachine, PassManager, etc. to generate my object code. The initial version of my code was cribbed from llc for

I’m new to llvm so I’m hoping someone can shed some light on this. I am trying to use the Kaleidoscope tutorial and cannot get past the 3rd part. All the llvm includes are not in their expected places. Eg… “llvm/IR/Verifier.h” is actually in “llvm/include/llvm/IR”. I am running mac osx 10.9. Here’s what I’ve tried: 1. checkout the svn of llvm, clang & compiler rt 2. created a “build”

Hi Dan, Thank you for you response. As you suspect, I am struggling with the building of LLVM/Clang. I thought building LLVM/Clang was required in order to build the tutorial and eventually modify for testing/learning. From what you are saying, it sounds like I am mistaken? In reference to what you mentioned about installing/building and —prefix and my misuse of my build directory: I am

Hello; I wanted to insert two new terminator instructions in LLVM IR. I modified the necessary files (as mentioned in the tutorial in LLVM site and some more to meet the new structure of LLVM, (e.g no Lexer.l now, we have LLLexer.cpp. Again in the tutorial, files like LLVMBitCodes.h, include/llvm-c/core.h that need to be modified are not mentioned) But I am getting the error while building

Hi, I want to add an integer field to all C++ classes in LLVM. Where do I look at in the LLVM source to make the necessary changes? As of now, what I understand is that I need to make changes in Type.cpp (llvm/lib/IR/Type.cpp) where I insert an integer field in the ArrayRef passed to StructType::setBody?

Hi, I was trying to create a new *Store* instruction and inserting it to LLVM IR (.ll) file. I found the following constructor in LLVM Manual: StoreInst::StoreInst <http://llvm.org/docs/doxygen/html/classllvm_1_1StoreInst.html#aa2a72f9a51b317f5b4ab8695adf59025> (Value <http://llvm.org/docs/doxygen/html/classllvm_1_1Value.html> * Val, Value

I am generating LLVM IR code and I would like to convert this IR code to native code using the LLVM C++ API. This would be very similar to what's done in the Kaleidoscope tutorial, but instead of relying on JIT compilation, I'd like to emit native code -- the same native code that's produced by llc, for instance. I'm sure this is possible, but I wasn't able to find the

Dear all, I'm using a Virtual Machine with Ubuntu 18.04 at VIrtualBox and I'm trying to build the LLVM project from https://github.com/llvm/llvm-project.git. This VM has 6 cores (from an intel core i-7 8th gen), 11GB of RAM and 300GB of storage (from a 1TB HDD) at a laptop, this is the model: MSI GS63 Stealth 8RE. Then, I'm doing exactly that this tutorial says to build LLVM:

I'm writing a compiler (originally targeting x86 asm, but now) targeting the LLVM IR. I am seeking some tutorial style information focused on: 1) Hand writing LLVM IR and/or compiler generated TEXT LLVM IR text source modules by my compiler 2) Purely static compilation and linking of modules written in LLVM IR (or compiler generated, clearly) 3) In sum, I'm only interested in using

Hi Everyone, I'm quite new to LLVM and I want to update value of global variable in LLVM IR. I created new global variable in ModulePass: bool runOnModule(llvm::Module &M) { IRBuilder<> Builder(M.getContext()); Instruction *I = &*inst_begin(M.getFunction("main")); Builder.SetInsertPoint(I); M.getOrInsertGlobal("globalKey",

Hi! I'm new to LLVM but I've read tons of articles, I want to implement my own compiler and I came across a big problem. I have several questions, that I cannot answer myself: 1) If I'm writing custom compiler do I have to "hardcode" passes that it uses (like in Kaleidoscope example: http://llvm.org/docs/tutorial/LangImpl4.html) or I have to generate LLVM IR and then use the

Hi all, I am trying to compile a high-level imperative OOP-like language to the LLVM IR. Do we have any "generic" way of translating a non-SSA form to the LLVM IR's SSA? There are lots of LLVM front-ends now. Do they do such translation individually? or there is some common non-SSA IR that we can translate to, and can be converted to the LLVM IR automatically? I did not find such

I don't think it's the same problem as you described. By printing I meant calling printf function and passing my global variable as one of the arguments. My code: Instruction* InstructionVisitor::incrementGlobalKey(Instruction* I) { IRBuilder<> Builder(I->getContext()); Builder.SetInsertPoint(I->getNextNode()); GlobalVariable* key =

Dear LLVM user and developer, We get a chance to give a tutorial on LLVM and MCLinker. The tutorial will be co-located with CGO 2013 on Feb. 24 (Sunday morning) in Shenzhen, China. If you are also interesting in these topics, welcome to join the tutorial! Here is a website of the tutorial: http://code.google.com/p/mclinker/ We're also looking for additional presenters to share a
