Thanks Joshua and Michael, Just to to clarify, I'm experimenting with the Interpreter class and observing the instructions that are executed by it. Just for becoming more confident with LLVM in general I'd like for each instruction to access to the various parts of it. In this instance I would like to access to the %Name that is shown in the textual representation. When I call

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 =

Hi Tim, Thank you for the quick response! so you'd probably check you're looking at a BranchInst and check BI->getSuccessor(0)->getName() (& 1 if it's conditional) I initially was printing out the result from getName() (I.getParent()->getName()) and it printed out nothing sadly. when parsing the instructions in SelectionDAGBuilder but it was only visiting instructions in

Hello, I’m trying to insert an instruction if a specific label name/string is encountered and would appreciate some guidance on where I should start. Basically when parsing going through this .ll file: ; Function Attrs: noinline nounwind optnone uwtable define i32 @main(i32, i8**) #0 { %3 = alloca i32, align 4 %4 = alloca i32, align 4 %5 = alloca i8**, align 8 %6 = alloca i32, align

The code you've pasted there is inconsistent in variable names. Your created an instruction called 'op1' but your print uses 'v1'. What should be an '->' is just a '-'. You also have a variable in your print called 'op' but that's not declared in your code. Also the result of dyn_cast should always be checked for null before using the result.

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)){ ...

Hello, I'm a newbie in LLVM. Now I'm trying to implement a pass that does some simple form of dynamic dataflow analysis. In my dataflow analysis I want to know if a specific variable is "dependent" on another one. "Dependent" means the following: if we have three variables in a program - a, b and c and in some places of this program we have the following

Hello, I want to display the variable names in stringref iterator. But it is not displayed using following code. for (set<StringRef>::iterator sit = L.begin(); sit != L.end(); sit++) { errs() << *sit << " "; } How to do this? Please help.. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Tobi, it looks like this code is the problem: for (std::vector<Value *>::iterator PI = Pointers.begin(), PE = Pointers.end(); ;) { Value *V = *PI; if (V->getName().size() == 0) OS << "\"" << *V << "\""; else OS << "\"" << V->getName() <<

Hi all， Im trying to instrument this hello function right before the instruction that call the "puts" function(the source code is as follow). Now I can compile the pass without errors, but when run the pass with opt tool, it broke down. The diagnose is something like Referencing function in another module! %CallCheck = call i32 @fib() Broken module found, compilation aborted! Does

Hi, I got upset.. What does “Broken module found, compilation aborted!” mean really?? what‘s “broken module“?? -- 祝好！ 甄凯 ------------------------------------------------------------------------------------------------------ 2012-04-09 ------------------------------------------------------------------------------------------------------ Name: 甄凯(ZhenKai)

Hi, I don't think the code you pasted can be the correct code, where does FibF come from? Anyway, the problem is that you're calling the FibF from Module A, however you defined it for Module B. You need to insert the FibF function into the Module that you're running. To do this override "virtual bool doInitialization(Module &M);" and insert FibF into M. Joey 2012/4/9

My friends, I ran a function pass on a .bc file, intending to insert a CallInst to my self-made check function. The compilation is successful. BUT after I ran that pass on the .bc file, the size of the file didn't get any bigger!! Does this mean my instrumentation work failed?? BTW the opt command I use is "opt -load ../../../Debug+Asserts/lib/Hello.so -hello <hello.bc> -o

i am using llvm , i did this if ( AllocaInst *allocInst = dyn_cast<AllocaInst>(&*bbit)){ PointerType *p = allocInst->getType(); if ( p->getElementType()->isPointerTy()){ StringRef name = allocInst->getName();
