I am looping through all instructions in a Function and depending on what I found I may or may not insert code. Despite the fact that I'm only actually inserting *before* instruction I have a infinite loop when I do something like below. For awhile it was simple enough to just increment i enough times but now I need something better. for(inst_iterator i = inst_begin(F); i != inst_end(F); ++i)

Hi. Thanks. I changed the code but the problem exists. This is my new code which is again very simple: ... bool runOnFunction(Function &F) override { vector<Instruction *> dels; dels.clear(); for (inst_iterator It = inst_begin(&F), Ie = inst_end(&F); It != Ie;) { Instruction *I = &*(It++); if (auto* op = dyn_cast<BinaryOperator>(I)) { IRBuilder<NoFolder>

hi how can i write IRinstruction on a file.txt? when i use  {for(inst_iterator I = inst_begin(F), E = inst_end(F); I != E; ++I,count++)  IRcodefile << std::basic_ostream(*I) <<"\n" } i get  error. is there any way that i can write it on file? -------------- next part -------------- An HTML attachment was scrubbed...

Hi, i want to get the address in memory of an instruction pointer and use it as a key in my tables. i iterate over the instructions in LLVM IR like this: for (Module::iterator fi = Mod->begin(), fi_end = Mod->end(); fi != fi_end; ++fi) { for (inst_iterator I = inst_begin(fi), E = inst_end(fi); I != E; ++I) { Instruction *ii = dyn_cast<Instruction>(&*I);

Hello, I think there's a rather subtle problem with the inst_iterator. It declares its iterator category as std::bidirectional_iterator_tag but C++ standard requirements for forward iterator (which are included in requirements for bidirection iterator), say that the type of expression *r; should be T&, where 'r' is the iterator and T is its value type. The inst_iterator,

LLVM is built in Release mode. The version is 6.0.0. I think that a similar code worked on verison 3.9.0. It is probably a null pointer dereference occurring in eraseFromParent(). I checked and reconfirmed that the instruction had no uses. Perhaps I should rebuild LLVM. Thanks. On Wed, Aug 8, 2018 at 9:03 PM, mayuyu.io <admin at mayuyu.io> wrote: > Hmmmm that’s strange.

I did a simple test just now, but I alse failed. I delete several ordered instructions from end to begin, but after deleting the first instruction(the last instruction of F), the program crashed. My test code is below (F is a function only containing several sequential instructions): for (inst_iterator inst == --inst_end(F); inst != inst_begin(F); --inst) { Instruction * i = &*inst;

Hi everyone, I am trying to write a pass, that finds some instructions and replaces them with my intrinsics, but I am having problem understanding, how this should be done. Let's say I have this instruction: %tmp14 = load i32* getelementptr ([32 x i32]* @gpregs, i32 0, i64 28) and i need to read the load's operands and replace it by let's say: %tmp14 = call i32

Hi, I want to extract all instruction of the form "alloca %struct.S", where $struct.S is defined as a struct %struct.S = type { i32, i32 } I'm using the following loop: for(inst_iterator i = inst_begin(F), e = inst_end(F); i!= e; i++) { AllocaInst* ai; if( (ai = dyn_cast<AllocaInst>(&*i))){ if(ai->getOperand(0)->getType()->getTypeID() ==

Hello all, I am a LLVM newer who want to obtain the use-def chain for all instruction of a sample code, for this purpose i use the following code. ///////////////sample code:///////////////////////// #include <stdlib.h> #include <stdio.h> #include <time.h> #define ARRAY_SIZE 5 int main() { int x, y, holder; int k,z,f,i; z=0; f=0; k=0; for(x = 0; x < ARRAY_SIZE;
