LLVM friends, I'm currently trying to make LoopVectorizationLegality class in Transform/Vectorize/LoopVectorize.cpp more modular and eventually move it to Analysis directory tree. It uses several file scope helper functions that do not really belong to LoopVectorize. Let me start from getPointerOperand(). Within LLVM, there are five other similar functions defined. I think it's time to

Dear All I'm trying to create storeInst using StoreInst *SI = new StoreInst(val, AI, BB); AI is an alloca instruction previously created, BB is the basicBlock I want to put instructionsi in. Val is the value to store. I've created val from a genericValue like this: Value* val = ConstantInt::get(getGlobalContext(), Result.IntVal); Result is the genericValue However I keep getting

What LoopVectorize.cpp has are the following. Each function may have to have a separate consolidation discussion. I'm bringing up getpointerOperand() since I actually found multiple instances defined/used. DependenceAnalysis.cpp has isLoadOrStore(). LoopAccessAnalysis.cpp has getAddressSpaceOperand(). I'm sure there are others that might be worth discussing within this thread or a follow

Hello all, I would like to create a new StoreInst into a basic block. I found that I could use methods like ConstantInt::get() to provide the Value* for the first argument of the constructor of the StoreInst, but I don't know how to provide the second one. For example, if I would to do x = 1, I would like to create the "Value" object of "x" for the second argument. I

Hi, I am trying to figure out the best way to add some extra metadata to the store and load llvm-ir instructions: The metadata content is a 'Value*' expression representing a side channel, containing dependency information that is used to help the Scoped Alias Analysis. Optimizations that don't know about this side channel can safely drop it, where the only effect would be on the

hi, i am writing a simple LLVM pass to analyze the Store instruction. my pass derives from InstVisitor class, and the method to handle Store instruction is like this: void MyPass::visitStoreInst(StoreInst &I) { ... } It is pretty simple to handle Store. however, in on test i got an instruction like below: store i8 %tmp5, i8* inttoptr (i32 301959828 to i8*) the second operand is

Hello everybody, my problem is, that I want to get an array of pointers to all local variables in a function. This array will be used for transfering these Variables to another execution engine. I've code which generates this array, and a pointer to the target field of the array. name = variables.fname + "_pointerArray"; Instruction* pointerArray = new

Hi, I am trying to write a simple interpreter. I am trying to generate LLVM IR for assignment operation. The code for the generation part looks like this llvm::Value* codeGenSymTab(llvm::LLVMContext& context) { > printf("\n CodeGen SymTab \n"); > Value *num = ConstantInt::get(Type::getInt64Ty(context), aTable.value, > true); > Value *alloc = new

I have a loop fully unrolled and got the following store instruction. store i32 %add.3, i32* getelementptr inbounds ([20 x [20 x i32]]* @c, i32 0, i32 0, i32 0), align 4 I want to know exactly which element of the array that is going to be stored, which help me to transform the high level language to hardware. Take the instruction above as an example, I know the data is stored into c[0][0]. It

Hi all, I am wondering the semantics of alignment in a StoreInst. For example, in the following code: %A = bitcast i8* %buffer to i32* store i32 %x, i32* %A, align 4 We have an "align 4" in the StoreInst. Does this mean 1) the address 'A' should be aligned to 4 bytes? 2) the lower 2 bits of 'A' should be always 0? Thanks Hongbin -------------- next part

Hi, I’m writing a loop-free LLVM pass, my thought is to track if the value inside the loop is changed, so I look up the Instruction StoreInst first and try to get its value in a set. I checked getValueOperand(), getValueName() in the API document but unfortunately they failed the compilation. if (isa<StoreInst>(I)){ Value* v = I.getOperand(0); Instruction* op1 =

I'm trying to create and insert a anonymous function that will make a assignment on a GlobalVariable, based on a existing StoreInst. Once I find this StoreInst(which provides me with 2 Value* objects for me to use) I need to pass it to my anonymous function so it can carry out the assignment. I can not get the correct types, at runtime I get a bad signature error. So basically the function is

It means the compiler will assume those facts when reasoning about
