[LLVMdev] The most efficient way to compile to LLVM IR?
Hi all, I am trying to compile my toy language to LLVM back end. (I am new to LLVM, so my questions may sound naive) I am looking at some tutorials about LLVM, most are about how to use LLVM IRBuilder, however, I find the API provided by IRBuilder is quite imperative and verbose, and the API changes so fast that most of the tutorials are out of dated. So I am wondering what's

Create an Add Instruction in LLVM IR
I want to create an add instruction that takes two constant operands at the LLVM IR level. I use the IRBuilder class, but nothing happens. Here is part of the runOnFunction() method of my function pass: ... LLVMContext &Context = F.getContext(); IRBuilder<> builder(&Instruction); Value *Lef = ConstantInt::get(Type::getInt32Ty(Context), 4); Value *Rig =

[LLVMdev] Representing -ffast-math at the IR level
Thanks for the updates! Minor comments: + if (!Accuracy) + // If it's not a floating point number then it must be 'fast'. + return HUGE_VALF; Can we add an assert instead of a comment? It's just as documenting and will catch any goofs. + // If it's not a floating point number then it must be 'fast'. + return !isa<ConstantFP>(MD->getOperand(0));

computing a subset using a loop
Dear all, I have a data frame with different variables and I want to build different subsets out of this data frame using some conditions and I want to use a loop because there will be a lot of subsets and this would be saving a lot of time. I try to give you an overview about my data frame. I have a data frame named "Baumdaten" and it has one column named "transectID" with

How to insert instructions before each function calls?
So one way might look like this: IRBuilder<> Builder(&*BB); // BB = Function::iterator OR IRBuilder<> Builder(CallInst->getParent()); Builder.SetInsertPoint(CallInst); InstructionClass *YourNewInstruction = builder.CreateInstructionClass(.....); // InstructionClass = type of instruction you are inserting -Ryan On Sat, Sep 3, 2016 at 6:04 PM, Ryan Taylor <ryta1203 at

Creating/Deleting a new instruction from LLVM IR
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

Difference between “uses” and “user”
Hi everyone, Instruction and Value classes have "Uses" and "User". What is the difference between them? I think that "Uses" gives all the instructions/values that a particular Value depends on and "User" gives all the instructions/values that depend on that particular value. Is that right?

LLVM IR intrinsics placeholder for strings [was Re: Back end with special loop instructions (using LLVM IR intrinsics)]
Hello. I come back to this thread. But I want to ask a slightly different question. Is there a way to have LLVM IR language intrinsics that are given at construction time a string that is written at assembly generation time as it is? (so, basically having placeholders of strings in LLVM that remain untouched until the end, including code generation time.) More exactly, I would

Fwd: I cannot change value of global variable in LLVM IR using IRBuilder
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",

[LLVMdev] Adding function call in LLVM IR using IRBuilder causes assertion error
Hi, I'm trying to add function calls in the LLVM IR using the IRBuilder class. I've read both tutorials about functions but I still get assertion errors. I allocate memory for all function arguments and pass them as explained in the tutorial. My code is (this function is supposed to add a call to f in bb at pos): void addCallSite(Function *f, BasicBlock *bb, BasicBlock::iterator pos)

[LLVMdev] Representing -ffast-math at the IR level
Here's a revised patch, plus patches showing how fpmath metadata could be turned on in clang and dragonegg (it seemed safest for the moment to condition on -ffast-math rather than on one of the flags implied by -ffast-math). Major changes: - The FPMathOperator class can no longer be used to change math settings, only to read them. Currently it can be queried for accuracy info. I split the

Fwd: [musl] strptime() question
There is incompatibility between R strptime and musl libc.

Fwd: I cannot change value of global variable in LLVM IR using IRBuilder
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.
