Hello everyone, Can you please tell me if it is possible in LLVM to cast a `Value*` to an `Instruction*/LoadInst*` if for example `isa<LoadInst>(MyValue)` is true? In my particular piece of code: Value* V1 = icmpInstrArray[i]->getOperand(0); Value* V2 = icmpInstrArray[i]->getOperand(1); if (isa<LoadInst>(V1) || isa<LoadInst>(V2)){ ...

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

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

Hi all, I am newbie for llvm. I just create a global variable, there are some statements in my pass like: LoadInst* int64_64 = new LoadInst(pthreadPID, "", false, OptAplusOne); int64_64->setAlignment(8); int64_64->dump(); LoadInst* int32_65 = new LoadInst(gvar_int32_myFlag, "", false, OptAplusOne); int32_65->setAlignment(4);

Hi Matthijs, Yes, I've turned off the link-time optimizations (otherwise it just propagates my constant vectors and immediate prints the result). :-) Here's essentially what I try to generate: void add(float z[4], float x[4], float y[4]) { z[0] = x[0] + y[0]; z[1] = x[1] + y[1]; z[2] = x[2] + y[2]; z[3] = x[3] + y[3]; } And here's part of the output from the online

Hi all, I have %5 = load i32, i32* %3, align 4 LoadInst and I would like to get reference to the destination ( in this case %5 ). How can I do that?

llvm does not automatically vectorize your scalar code (as least for now). You have to write gcc generic vector code or use vector builtins.

Hello, I have a problem of generating a load instruction. The LLVM bytecode is: ------------------------ entry: ... %2 = call i32 (...)* @atoi(i8*%1) nounwind /*<- Insertpos*/ ... -- bb1: .. %5 = icmp sgt i32 %2, %i.0 ... ----------------- Now I have pb: pointer to the Value object of *%2* of bb1. Here, I want to generate a load instruction and I did it as: new LoadInst(pb,

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 would like to get the '5'. I would like to know where the loaded value is stored. I don't know which method I should use of the LoadInst class. Hope this clarifies Thanks On Wed, Dec 12, 2018, 20:37 Doerfert, Johannes Rudolf <jdoerfert at anl.gov wrote: > The LoadInst is %5.

Hi all, How can I create an llvm::GetElementPtrInst in which the pointer and the index are in registers previously loaded with llvm::LoadInst ? I mean, the generated instruction will be like this: %1 = getelementptr i8* %myreg1, i32 %myreg2 here, %myreg1 and %myreg2 are previously created by load instructions (llvm::LoadInst). Please, let me know if there is an example of something similar.

Now I have an address that present in a unsigned long address like the following format: Value* addr = CONST(0xc0008000) But I do not know how to read the data from the above addr varaible. I tried the following three kind of code: 1. Code: Value* addr = CONST(0xc0008000); Value* data = new LoadInst(addr, "", false, bb); Error: Segmentation fault 2. Code(

My pass is looking at StoreInsts acting on global variable that happen to be function pointers. From these StoreInsts I would like to get useful information(the function used if a direct assignment, function pointer used, etc) from the getValueOperand() method. Looking through several examples I see that this can return several things like: GlobalVariable, Function, LoadInst or BitCastInst

Folks, I have a LLVM instruction like the following %0 = load i32** %pp, align 8 I have a LoadInst &inst handle to this instruction. In addition, i could access the pointer being loaded from using the inst.getPointerOperand... However, is there a way to access the handle to the value being loaded? Essentially, i wanted to access the %0 in the statement listed. The end goal is

Hi, guys. I'm a newbie to LLVM and have a very simple question. Which instructions should I use (in terms of IRBuilder calls) to allocate an array of bytes in stack (alloca?), then to work with it (from a given offset) as with integer (bitcast?). I mean something like that: unsigned char var[8]; unsigned int offset = 3; int val = *(int*)(&var+offset); /* read */ *(int*)(&var+offset)
